UPDATE: In 2019 I posted a patent filed in September 28, 1946, for a “body attachment”. Yesterday, on an unrelated search, I discovered the names of the same parties, under a different lawyer, related to a patent filed a month earlier (August 12, 1946)  for a “body extension” for a jeep. The second patent is more detailed (seen at bottom) than the early one. Both were approved on the same date: June 5, 1951. See most of the body extensions produced over the years in this post. 

Filed August 12, 1946:

Attorney Roy Whittington assigned half this patent to William Isler and half, jointly, to Julius Negin and Ludwig Gaspar, the two who also filed the patent at bottom. The whys are likely lost to history.

PATENT DESCRIPTION: June 5, 1951 R. D. WHITTINGTON BODY EXTENSION FOR MOTOR VEHICLES Filed Aug. 12, 1946 A TTORNEY.

Patented June 5, 1951 BODY EXTENSION FOR MOTOR VEHICLES Roy D. Whittington, Belton, M0., assignor of onehalf to William Isler and one-half to Julius A. -Negin and Ludwig J. Gaspar, J r., jointly, all of Cleveland, Ohio Application August 12, 1946, Serial No. 690,019 3 Claims. (01. 296-28) The present invention relates to vehicle-construction, and particularly to commercial vehicles such as trucks and the like, and aims to provide a practical form of extension for the body portion of such vehicles.

The invention has special reference tothe commercial type of motor vehicles such as have been known generally as jeeps in the army service, and which has a body of limited proportions and some forms of which have .an endgate at the rear end of the body. 7

Accordingly an object of the invention is to provide an extension of the body structure of this type of vehiclein the form of an accessory unit which is adapted to be mounted in the manner of a replacement for the endgate of the .vehiclebody and to receive said engate as a supplemental attachment serving the endgate function for said accessory unit….

Patent filed September 28, 1946:

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. The only thing is that Newgren had double supports, while the patent only shows a single support underneath.

PATENT DESCRIPTION: ATTORNEY Patented June 5, 1951 BODY ATTACHMENT FOR JEEPS Julius A. Negin, East Cleveland, and Ludwig J.

Gaspar, Jr., Cleveland, Ohio, assignors of onehalf to William Isler, Cleveland, Ohio Application September 28, 1946, Serial No. 700,006

11 Claims. 1

This invention relates, as indicated, to body attachments for vehicles of the type known as Jeeps.

As is well known, this type of vehicle, which was developed and extensively used during World War II, is coming into general usage for commercial purposes, but its use for such purposes is somewhat limited on account of its body shape and dimensions.

Another factor which has inhibited the use of this type of vehicle for commercial purposes is the fact that the spare tire or spare wheel of the vehicle is conventionally carried at the side of and adjacent the rear end of the body of the vehicle, in which position, it is so remote from the plane defined by the wheels of the vehicle as to constitute a hazard, particularly when attempting to park the vehicle in city streets.

The present invention has as its primary object the provision of an attachment or extension for the body of a vehicle of this type, which attachment or extension materially increases the carrying capacity of the vehicle. Continue reading →

Harvey Rust submitted this patent for an adjustable scraper blade mount on April 1, 1949.

“This invention relates to scraper blades of the bulldozer type such as used in leveling or pushing snow, dirt and the like, and in particular a blade mounting for removably attaching a blade to the front of a Jeep or the like wherein the elevation of the blade is readily adjustable and in which the blade is hinged and resiliently held to provide tilting movement when the lower edge of the blade engages a fixed obstruction.”

C.W. Musser filed a patent for a “Gun Aiming Mechanism with associate trigger release mechanism and supporting mount” on February 24, 1953. This illustration with the gun on a jeep accompanied the patent.

“Fig. 1 is a side view of my gun aiming mechanism and associated trigger release mechanism with supporting mount shown in heavy solid line. For purposes of illustration the aiming and trigger release mechanisms are applied to a typical, large caliber recoilless rifle and its attached spotting rifle (both shown in light solid line), and the supporting mount is secured to a representative motor vehicle which takes the form of the jeep (also shown in light solid line). For simplicity of drawing the customary sighting system for the guns has not been shown.”

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?

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.”

This Liftmobile patent was filed by Schultz Kurt-Gunnar on January 16, 1960. This seems to be the only patent related to the jeep that he filed. I can find no evidence that this

According to the patent, “The present invention aims at providing an improved elevator-type motor truck or liftmobile, repowered, equipped and counterbalanced for faster transportation of the load under care, to more distant places, even off the road, where they may be urgently needed under adverse conditions, as after accidents, during strikes, rebellions, forest fires, etc.

More particularly, the present invention aims at adapting a motor vehicle or truck, for example, a commercially available vehicle such as a Jeep, by appropriate modification and reconstruction thereof to quickly pick up the load at a depot from the ground or from a lorrys platform, for instance, canned food and refreshments, packed in boxes, first-aid material, barbed wire spools, bundled on pallets, and various other auxiliary and protective articles, to expeditiously travel with the load at the usual convoy speed, about 25-30 m.p.h., even over rough ground and in roadless country, and to promptly deposit the load in dangerous places under fire from rebels, at dark, by dumping, i.e., without necessity of stopping the vehicle for purposes of unloading.”

Delmar Roos invented and Willys Overland patented this dual-driving-axle suspension on November 27, 1941.

According to the patent, “‘This invention relates to spring suspension for motor vehicles, and more particularly to vehicles of heavy duty or commercial type wherein the four rear wheels are mounted on tandem driving axles.

One of the principal objects of the invention is to provide means of mounting or connecting the axles to the chassis frame in such a manner so as to permit independentl vertical movement of the axles with respect to the frame without setting up undue strains in the connecting means, or materially restricting the vflexibility of the springs as the vehicle travels upon rough or uneven road surfaces or terrain.”

This “Frangible Frame All-Purpose-Farm Implement 2” was filed by Albert H. Stockmar on September 5, 1945.

According to the patent, “The principal object of the present invention is to provide a composite agricultural machine which is capable in a single operation of performing a plurality of related functions such as cutting sta ks. listing beds, leveling beds, planting seed and placing fertilizer.

Another important object of the invention is to provide a composite agricultural machine of the type described wherein the supporting frame is constructed substantially entirely of welded metal tubing which may be relatively inexpensively produced and which will require a minimum of maintenance attention in operation.”

Inventor David Stone filed a patent for a Power Take-Off Mechanism and Drive Therefor, with Willys Motors as the assignee, on August 08, 1950.

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??
