FC-170 Power Hoe Patent

I had this post all completed, then went to add some background information when I discovered that Craig had already added the first page of the patent to his post about the FC-170 Power Hoe. So, lots of heavy lifting in terms of content can be found here, while below you can view the whole patent. I think the illustrations are pretty neat.

1945 Patent for a Jeep Bulldozer Attachment

• CATEGORIES: Features • TAGS: This site contains affiliate links for which I may be compensated.

On October 11, 1945, George W. Mork patented the first bulldozer attachment for a jeep as part of his work with Caterpillar Global Mining company. I don’t recognize the design, so I don’t think this was ever produced commercially, but maybe Caterpillar used it??

Jeep-A-Loader

• CATEGORIES: CJ-2A, CJ-3A, Features, Unusual • TAGS: This site contains affiliate links for which I may be compensated.

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.

From June 2008:  A reader named Ed sent me some pics of a rare find he just purchased:  A front end loader for a jeep from a manufacturer called Jeep-a-Loader.   The serial number is 1001. The hydraulics system is powered by a Hy-lo hydraulic pump, which has been used to power other Willys devices.  You can see an example of a Hy-lo pump here and here.  Here are some pics below.

Stratton Hydro-Implement Lift Information

• CATEGORIES: Advertising & Brochures, Features • TAGS: This site contains affiliate links for which I may be compensated.

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.

Dual Wheel Adapters

• CATEGORIES: Features • TAGS: , This site contains affiliate links for which I may be compensated.

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 President of Northwestern Auto Parts Company (aka NAPCO).


Here is an example of them:

This December 1947 NAPCO ad promoted the hubs:

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.

This Photobucket page has some good close up photos of the Hickey adapters. Continue reading
