1956 Patent for Endless Track Vehicle

• CATEGORIES: Documents, Features • TAGS: .

This patent application used a jeep to demonstrated how the endless track system would work on a vehicle not designed specifically for tracks. The patent was filed January 13, 1955.

According to inventor Fritz Riemerschmid, “Numerous constructions of the track! laying or crawler type have heretofore been proposed, but in all of these known cases special-type vehicles are involved, the construction of which either prohibits or renders extremely difficult the use of the vehicle under normal road and travel conditions.

Accordingly it is one of the main objects of the present invention to provide a crawler-type tracklaying undercarriage for automotive vehicles which, while being particularly suitable for travel over snow-covered terrain, can be quickly and easily substituted for the standard wheels of the vehicle. It is another object of the invention to provide a construction of the type indicated in which, except for the removal of the said standard wheels from the vehicle, requires no structural changes to be made in a given vehicle. Thus, the invention renders it possible, whenever it may be desired, to provide an automotive vehicle of any given type with a tracklaying mechanism which takes the place of the standard wheels on which the said vehicle normally travels.”

The K And K Mower Patent

• CATEGORIES: Documents, Features • TAGS: .

In February of 1948 Allan Keyser filed a patent for a side mower. It appears this became the design for the K And K Manufacturing Company’s Mower as seen in the brochures at bottom. You can view other early mowing apparatuses here.

“This invention relates to a mower attachment for the presently popular small, four-wheel drive, automotive vehicles popularly known as jeeps, and has for its principal object the provision of means whereby a mower bar can be quickly and easily attached to, or detached from, the vehicle so that it will be easily visible and easily controlled by the driver of the vehicle.

Another object of the invention is to provide highly efficient means whereby the angle of attack of a mower bar may be adjusted to suit the desires of the user and the requirements of the particular crop being harvested.”

The 1954 Power Tower Patent

• CATEGORIES: Documents, Features • TAGS: .

This April 12, 1954, Power Tower patent filing by Wallace Johnson and Robert Fisher was said to be designed for other vehicles besides the jeep, but given it’s length, it’s hard to imagine it would work on anything that wasn’t flat like the top of the jeep.

Here’s a description:  The present invention relates to a power tower for use by workmen employed as painters, electrical fixture repairrnen, aircraft maintenance men, window washers, and a multitude of similar occupations wherein it is necessary toperform a task at some distance above the ground and thus ordinarily require the use of ladders or scaffolding of some type.

1950 Mechanical Bola Patent

• CATEGORIES: Artists/Drawings, Features • TAGS: .

A patent for a Mechanical Bola was patented on September 23, 1952, by B.D. Manning with the purpose of helping a single person rope and manage cattle. The drawing reminds me of the early modified Texas hunting jeeps like this one.

1950-09-20-mechanical-bola

“A peculiar trait of such cattle is their curiosity with respect to motor vehicles. They soon become accustomed to jeeps, for example, and will come up to examine one, particularly if the motor is running. One can drive right up to a bunch of cattle in a jeep, without any of them taking the trouble to move, so long as the driverstays in the car.

With the device of my invention attached to aj eep or other auto vehicle, it is a simple matter to capture a single animal without waste of time, or if it becomes necessary to inspect or treat a large number of cattle for Screw-Worm or other disease, this may be done expeditiously, for if the rest runoff at the casting of one animal curiosity brings them back shortly if the driver moves his vehicle about a bit.”

1959 Patent for a Portable Reeling Device

• CATEGORIES: Features • TAGS: .

The patent for this portable reeling device was filed on December 25, 1962. It isn’t just for a jeep, but a jeep-like vehicle is shown and referenced. I’ve never seen any evidence this was ever manufactured; anyone else?

 

1959-01-26-portable-wire-reeling-device-patent

From the patent, “Now with more particular reference to the drawing, FIGS. 1, 2, 3, and 4 show an embodiment of the invention with a jeep as the means to drive a power driven communication wire reel 16. The communication wire is retrieved and wound onto the communication wire reel 16 by activating outwardly an adjustable speed disk 31 with a clutch lever 20. The power to perform this function is derived from a power take-off 38 from the engine.

Persons familiar with jeeps of the military variety know that such jeeps have a transmission which connects the motor to two shafts which are connected in parallel. One of the shafts drives the ground engaging wheels of the vehicle while the other shaft is connected to a power take-off. This power take-01f may be used to drive a hydraulic system or other attachment. In this case, the power take-off 38 is connected to the shaft 37 and thence to a universal joint 36 and, from there, to the clutch for driving the reel. A pressure spring 35 is held in place and away from a spinning friction power disk 33 by means of a bearing 34 which is fixed to the friction power disk 33. The constant pressure which is exerted on the bearing 34 forces the friction power disk 33 outwardly and against the adjustable speed disk 31. By moving the clutch lever 20 to the left, a pivot 40 in a clutch lever support plate 22 will force lever lugs 39 to the right.”

1946 Patent For a Body Extension

• CATEGORIES: Features • TAGS: .

I can only guess that this design was used by Newgren, as I *think* it was the only firm that built a collapsable body extension. See many of the body extensions documented here. The only thing is that Newgren had double supports, while the patent only shows a single support underneath.

Jeep-A-Loader

• CATEGORIES: CJ-2A, CJ-3A, Features, Unusual • TAGS: .

UPDATE: This is the original patent for the Jeep-a-Loader! The application was first filed on February 07, 1955, by the Minneapolis Freeman Mfg, Co. (Out of Minneapolis??). I am guessing that the Jeep-A-Loader Corporation was a subsidiary or offshoot from the above parent company. The drawing shows that the Jeep-A-Loader was designed to fit over a CJ-3B (perhaps a CJ-5 as well), though the only one I’ve seen documented is fitted on a CJ-3A.

The filing date likely means this was manufactured around 1955, plus or minus a year. The patent was granted February 11, 1958.

Stratton Hydro-Implement Lift Information

• CATEGORIES: Advertising & Brochures, Features • TAGS: .

UPDATE: Nate’s hoping to gather some Stratton-related information. So, I’ll be using this post to gather that info. If anyone has any more insights into this lift, email me at d@ewillys.com or post it directly to Nate’s thread on the earlyCJ-5.com page.  Also, Clint Dixon and Barry Thomas have authored a five-part series of articles for the Dispatcher Magazine titled “The Making of the Farm Jeep”. The Fall of 2018 issue includes information on the Stratton Lift. 

As early as 1949 Stratton Equipment out of Cleveland, Ohio, was marketing hydraulic products. One example was their truck lift, a hydraulic lift used for placing cargo onto truck beds. The lift is pictured at the top of page 146 in the October 1949 issue of Popular Mechanics. This was just one of multiple patents filed over the period of three decades (1940s-1970s) by Alfred F. Foote, product designs both jeep-related and non-jeep-related.

1) On July 27, 1960, Alfred F. Foote filed a patent for the Stratton Lift with the Stratton Equipment Company as the assignee. Due to the lack of information related to Stratton lifts, it was unclear to most when this product hit the market. Given the patent date, the lift likely entered the market in late 1960 or later.

As part of his patent, Foote references both the Monroe and the Love designs. The patent for the lift was granted on Feb. 26, 1963.

Cutlas Manufacturing

• CATEGORIES: Features • TAGS: , .

UPDATE 2: Niels shared a photo of his rare Cutlas key that can be used to spin the screws of the Power-Lock Hub.

UPDATE: 1) Well, it seems I forgot to read through this and edit it (I murdered the title for example) 2) The ending of the post has changed, thanks to Paul spotting an ad in the 1976 issue of Four Wheeler Magazine.

cutlas-power-lock-brochure-lores

This is a Cutlas brochure for the company’s first hub, the Power-Lock.

In January of 1958, James Russell Lloyd, who up to that point had been president of the Free-Lock Company in Denver, filed a patent for a new type of hub on behalf of a company called the Cutlas Tool and Manufacturing Company out of Lyons, Illinois. At the time, Lloyd was still based in Denver (according to the patent filing), so what his relationship was with the Cutlas and Free-Lock companies at that time isn’t clear.

cutlass-power-lock-hub-patent

Patent was awarded in January of 1962.

Unlike the Free-Lock hubs, which relied on a rotating center piece to engage and disengage the hubs, the Cutlas hub had two rotating screws that had to be spun to engage and disengage the hubs.

In May of 1958, Lloyd copyrighted the term Power-Lock Free Wheeling Hub, a name which the hubs would be known as from then onward. Here are some photos:

Kelly Manufacturing Self Locking Hubs

• CATEGORIES: Features • TAGS: , .

In May of 1957, DA Ruben L. Beck filed a patent for a new hub design. Beck was a dreamer and like many dreamers, some saw him a genius while others thought him just plain crazy. Beck’s goal was to create a simple, but effective, four-wheel-drive hub.

kelly-hubs-da-ruben-beck-patent2 kelly-hubs-da-ruben-beck-patent1

Beck had already made an early impact in the jeep world, when he founded D.L. Beck Manfucaturing in Middleport, Ohio, a company that made hardtops (see Beck hardtop history here).

1954-beck-all-steel-cab-brochure1Beck sold his hardtop company to Hubert A. Kelly, in the 1950s but Beck and Kelly remained in contact. The date of the sale, thought once to be 1951, is less clear after this document hit eBay in 2014. It indicates Beck was still selling hardtops in 1954.

1954-beck-all-steel-cab-brochure3

No matter when the sale occurred, Hubert took control. It wasn’t long after the patent filing that Mike Kelly, Hubert Kelly’s descendent, remembered seeing the hubs for the first time. He thought that was about 1958. I asked that he review the patent and Mike sent me the following notes:

“The Kelly Self Locking Hub I knew a was little different than the one pictured in the patent drawing. The housing was larger in diameter and had reliefs milled along the outside to allow clearance for the mounting bolts. The internal parts looked very similar to what I remember. I’m pretty sure the final Kelly product was a Beck design. I don’t recall anyone else working on it.

The hubs were manufactured in Charleston West Virginia. We already had an large machine shop there on Broad St. So moving production from Ohio to West Virgina was only logical. I know the assembling the hubs could be “interesting” if you weren’t watching what you were doing. Putting the internal workings together with the ball bearings being under spring pressure woke up more than one man who wasn’t paying attention.”

Thor Products & White Automotive (Whitco)

• CATEGORIES: Features • TAGS: , .
colorado-map-products2

More information on some of these companies can be found here: http://www.ewillys.com/2019/07/08/selectro-husky-dualmatic-overview/


White Manufacturing Co. (also known as White Automotive and Whitco over time) was started in the late 1950s by Richard T, Bingman and partners. The company progressed at a modest level making, among other things, aluminum floral display stands. Eventually, White allied with Kaiser and began making tops. White filed for incorporation in 1959. One of the company’s earliest products was a white soft top for jeeps.

The next year, in 1960, Richard T. Bingham filed a patent for a pair of locking hubs. One set would automatically shift into gear when it sensed the axles were being powered (i.e., when the transfercase was shifted into four wheel drive). The second set of hubs added a dash-mounted button to allow for control of the hubs from the driver’s seat (assuming I have interpreted the patent correctly!).

The interesting thing is that Bingham never assigned the patents to the White Automotive Company. Instead, the patents and hubs ended up being used by Thor Products, which also operated out of Colorado Springs (though sometimes the address is Manitou Springs, a small town just west of Colorado Springs).

thor-automotive-logoThis suggests that Bingham had some time of relationship with Thor, but his exact connection to Thor isn’t known at this time (my guess is that it was a subsidiary or sister company of White).

The Huffman Hub Company of Albuquerque, NM

• CATEGORIES: Features • TAGS: , .

UPDATE: Dan shared pics of a set he just bought from Paul:

huffman-hub-company-hubs-lores

Post originally Published April 8, 2017:

hoffman-hub

In December of 1958, Floyd G. Huffman filed a patent for a new type of hub structure. His patent, designed to “provide a hub structure that can be simply and quickly manually operated to release the front wheels so that they will rotate freely on the axles without the necessity of having the gears etc. rotate simultaneously when the front wheel drive has been disengaged” was finally approved in April of 1961. Later that year, in October of 1961, he filed incorporation papers for the Huffman Hub Company. He was a one-man show and enjoyed his independence. One of the hub’s unique features was a weapon-like piece of steel that sat atop the hub (but not evident not he patent).

1958-huffman-hub-patent1 1958-huffman-hub-patent2

Between August 1964 and May of 1965, Huffman advertised in Four Wheel Magazine. Perhaps by the summer of 1965 he’d built up enough dealers (150 in eight states), that he didn’t see the point of advertising? That isn’t clear.

1965-01-fourwheeler-huffman-hub-ad

According to a 1967 article (that includes a photo of him that I was too cheap to pay for), when he needed money, he hit the road, obtaining hub orders in New Mexico, Arizona, Texas, California, Oregon, Idaho, Utah and Colorado. Then, he’d return to his home in Albuquerque and, with the help of his granddaugther, would machine, assemble and ship the hubs. He claimed he was making 100 hubs a month and he saw great potential in reaching 1000 hubs a month.

I could find no more information on Huffman and his hubs after 1967, but I suspect the financial realities of operating a one man show proved impractical and he shut down the business.

Dual Wheel Adapters

• CATEGORIES: Features • TAGS: , .

UPDATE: See more information on the Rapport, Flox Foy, and Welliver adapters here.

I’ve spent the past couple days working through the selective hub relationships between Free-Lock (Denver, CO), Dualmatic (Longmont, CO), Husky (Longmont, CO), White Manufacturing (Colorado Springs, CO), and Cutlas Tools & MFG (Vinton, IA). During that process, I ran across more information about dual wheel adapters for the jeep. I thought it might be worth listing the one’s that have been documented. Perhaps someone has more information??

1. Max Rappaport’s hubs: A patent on these hubs was filed in 1947 (awarded in 1953), making them the earliest known hubs. Max Rapportaport was the Presdient of Northwestern Auto Parts Company (aka NAPCO).


Here is an example of them:

This December 1947 NAPCO ad promoted the hubs:

1947-12-popular-science-dual-wheels-dually

This July 1948 Popular Mechanics ad might be advertising the same dual wheels, but rebranded as “Du All” Converters. The design looks very similar to the Rapport models:

1948-07-popular-mechanics-du-all-dual-wheel-adapters-ad

 

2. Welliver Jeep Dual Adapters No. 3000: These adapters were available by 1949 and sold by the Welliver Machine Shop. This April 1949 ad from Popular Mechanics provides a documented date.

Thanks to Stefano Oddo, we have this brochure regarding these adapters:

jeep-dual-adaptors-no-3000-welliver

3. Hickey Dual Adapters: Vic Hickey developed his higher compression head, giving jeeps a power upgrade option. Then, he designed a set of dual wheel adapters. The first documentation I could find on his adapters was this July 1952 article in Popular Science about his hubs.
