AUTO-CONVEYER.

Specification of Letters Patent.

Patented Nov. 2, 1920.

Application led. September 20, 1919. Serial No. 325,184,

To all whom fait may concern.'

Be it known that i, EARTHEN H. CAM- rinLD, a citizen of the United States, residing at Florence, in the county of Fremont and State of Colorado, have invented a new and useful Auto-Conveyen of which the following is a specification.

lThis invention relates to an auto conveyer, that is a device adapted to be used for conveying or pulling automobiles such as pleasure cars, trucks or tractors or motor driven vehicles from mud, sand, ditches or any place where a machine loses the tractive power of or use of one or both rear wheels, the device being intended to pull the machine at any angle desired by placing the conveyer in the angle at which the car is to be pulled.

A further object of the invention is to provide a device for the purposes stated which is provided with means for securing one end thereof to an automobile wheel or the like and for anchoring the opposite end against movement so that upon the wheel being driven, the conveyer will coil around the wheel, thus pulling the machine from where it may be lodged.

A still further object of the invention is to provide a device of the class specified which may be made in different lengths or in sections to be used for short or long pulls or can be employed as a mud or anti-skid chain or tow rope without injury thereto, while also permitting renewal of worn parts and repair at small cost, as well as insuring that the conveyer will not become displaced from the tire of the wheel and which will be of simple construction, economical to produce, strong and durable and which will he prevented from slipping on the ground surface.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed without departing from the spirit of the invention.

Referring to the drawing Figure 1 is a side elevation showing the improved. conveyer as in use and connected to the automobile Fig. 2 is a plan view thereof detached from the wheel.

Fig. 3 is an enlarged fragmentary side elevation of a portion of the device.

Fig. 4L is an enlarged transverse section taken on the line l-t of Fig. 2.

Fig. 5 is an enlarged sectional view of one of the hangers taken on the plane of the section line 5*.5 of F ig. 2, and

Fig. 6 is a transverse sectional view taken on the line 6-6 of Fig. 5.

Referring to the drawings in detail, my improved conveyer is shown as including spaced parallel side members 10 preferably of good iiaX rope picked especially for the purpose, though it is to be understood that the essential characteristic of these side members is that they are flexible and strong. These side members are provided at spaced points equidistantly along the lengths thereof with pairs of apertures 11 located in opposed relation and receiving therein casings 12.

These casings are designed to receive hangers 13 arranged in pairs at opposite ends of webs 14 comprising tread sections extending transversely between the side members in spaced relation as specified. These hangers are preferably of metal and riveted or otherwise fastened to the webs 14; as shown at 15, the hangers being provided with elongated flattened inner end portions for this purpose and having their outer ends apertured for receiving locking pins 16 transversely therethrough. These pins are located outwardly of the side members and extend in the same direction as said side members, so that the apertures 1.7 receiving them are horizontally positioned.

The webs 1li are preferably made up of heavy canvas and each web consists of five plies or thicknesses the bottom of which is studded with steel lugs as shown at 18 so as to prevent 'the webs or tread sections from slipping. The locking pins 16 are reduced in diameter intermediately of their lengths as shown at 19 and mounted in the ends of the hangers 18 are spring catches 2O which engage the reduced portions and prevent displacement of the pins from the apertures of the hangers.

The side members 10 are of twisted rope so as to give the proper strength and flexibility and have secured thereto near one end of the straps which are located in so 'i 'tened about a wheel in the manner shown in F ig. l of the drawings, when a vehicle becomes stuck in a bog or the like so as to render one or both of the rear or drive wheels ineffective for traction purposes and `the opposite end isconnected to anY anchor- -ing` member or stake 25 preferably of metal so that it can be readily driven into the ground.

rllhis connection is effected through the medium of a swivel joint or universal link 26, the saine being connected to the side members by bending or tl'irning a piece of rope forming the side members, upon itself or bringing said ends near the staketogether and fastening as specified. The stake Yis further provided with a handgrip 27 by which it may be readily withdrawn after use. ln the use of the device, the stake is driven into the ground yat the forward end oi' the conveyer and the straps are attached to the wheel at the other end so as to form a member of a substantially semi-circular cross section or'channel shaped for the wheel whereby te render it impossible Jfor the wheel to slip either way. rfhe drive wheels are-then operated and as the webs or tread sections are held from slipping, a direct pull will be provided so that when the wheels start to revolve, the conveyer will coil about the wheel and cause the machine to be conveyed or pulled from the place where it is lodged. ln this manner, an effective device for the purpose stated is provided and onewhich can be readily applied for use and removed after use. Y

Having thus described the invention, what is claimed is l. A device of the class described comprising spaced side members of rope having reinforced openings therethrough arranged iu spaced pairs, webs between said sidemeinbers in parallel relation and comprising a plurality of plies, one of which is studded, hangers at the ends of the webs engaging the openings, detachable retaining means on the hangers outwardly oi the side members, spaced securing straps Vcarried by the side members near one end, and a stake swiveled to the other end.

2. The combination with an auto conveyer including spaced side members having openings therethrough and webs between Vsaid side members and having hangers extending through said openings, said hangers having openings therethrough; of pins disposed through said openings and spring latches engaging said pins to retain the same in position. r

In testimony that I claim the foregoing as my own, l have hereto ailixed my'signature in the presence of two witnesses.
