AUTOMOBILE DRAFT ATTACHIMENT.

No. 90.3,4a.

Specification of Letters Patent.

Patented Nov. 17, 1908.

Application filed Kai-ch 10, 1908. Serial No. 420,231.

mechanically propelled road machines, that e the same become stalled either because of machine when stalled from any of the causes muddy or soft roads or by the wheels dropping'into a depression in the road. When the engine is started, the drive wheels turn and byfailure of sufiicient traction between them and the road the machine remains unmoved.

This invention provides means whereby a aforesaid, may be enabled to move itself by a positive pullin force independent of or in conjunction wit the traction between the drive Wheels and the surface.

The attachment consists of a drum fitted to oneor both drive wheels, a rope or cable having one end attached to said drum and adapted to wind thereon, and anchoring means applied to the opposite end of said rope or cable for securing the same so that as the rope or cable is wound upon the drum the machine is moved in the direction of the anchored end of said rope or cable.

For a full understanding of the invention and the merits thereof and also to acquire a knowledgeof the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings.

While theinvention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which:

Figure 1 is a side 'view showing the application of the invention to an automobile the latter being indicated in dotted lines and the rear' drive wheel in full lines, Fig. 2 is a detail view of the central portion of the drive wheel showing the attachment in position, the drum being in section. Fig. 3 is a horizontal section of the parts shown in .Fig. 2. Fig. 4 is a detail pers ective view of the ring. Fig. 5 is a detai perspective view of the drum.

Corresponding and like parts are referred to in the following description and indicated inall the views of the drawings by the same reference characters. w

The drum 1 is flanged at opposite ends and is tapered preferably and arranged with the larger end adjacent to the drive wheel so as to prevent the rope or cable from interfering with the tire of the wheel. The drum may be of any construction and is preferably of metal so as to be light and strong and enable thespace being utilized for storing purposes. The drum is. adapted to be detachably connected to the drive wheel so that when not required for immediate service it may be conveniently carried in the boot or other place set aside upon the machine for storing tools and adjunctive parts. Arope or cable 2 is attached at one end to the drum 1 and its opposite end is provided with a pin 3 which is adapted to be driven into the road to anchor the rope or cable when it is requiredto bring the appliance into active operation. A second pin 4 is connected by a short rope or cable 5 to the upper end of the pin 3 and serves as a stay therefor. A rope or cable maybe of any lengthzand of any make and when the outer end is anchored or made fast'at some distance from the-machine and the engine is started to impart motion to the drive wheel,

the drum 1 is rotated and winding the rope or cable 2 thereon imparts positive motion to the machine and pulls the same out of a depression or other place in which the machine may become stalled.

A ring 6 is secured to each drive wheel of the machine and is preferably left in place, although this is not essential. Clips 7 cmbrace spokes of the drive wheel and serve to connect the ring 6 thereto. The drum 1 1s adapted to'be secured to the ring 6 by any means, such as hooks 8 and a clamp 9, the hooks 8 being adapted to engage over the outer edge of the ring, whereas the clamp 9 is movable and secured in place by means of a bolt or like fastening 10. The clamp 9 is approximately of U-form so as to embrace the ring 6 and the adjacent flange of the drum 1 and is adjustably connected with said flange by means of headed studs 11 passed through openings 12 formed in a member of the clamp 9. -The ring 6 is formed with a crimp 13 for the passage of the bolt 10, said bolt-operating in anopening formed in the closed end of the clamp 9. 4

When the bolt or fastening 10 is loosened,

the rum may be either fitted to a ring 6 or removed therefrom, and when in place the I hooks 8 and the clamp 9 engage over the outer edge of the ring 6 and when the bolt 10 is tightened after placing the drum in position, the parts are made secure and the attachment adapted to operate in the, manner set forth.

Havingthus described the invention, what is claimed as new is:

1. In combination, a rin secured to the drive wheel of an automo ile or like machine, a drum provided with 'hooks to engage with said ring, a clamp acting in obnjunction with said hooks to secure the drum to the ring, and a rope or cable coiiperating with the drum and a apted to wind thereon, to positively move the machine when stalled.

and a rope or cab cocaine 2. In combination, a ring, means for securing said ring to the drive wheel of an automobile or like machine, a drum rovided with hooks toengage with said ring, a clamp acting in conjunction with the hooks to secure the drum to the ring, said ring having a crimp to rovide a space between it and the adjacent end of the drum, a fastoning passed through the space formed by said crimp and ada ted to secure the clamp, Ye cooperating with the drum to positively move the machine when stalled.

In testimony whereofil affix my signature in presence of two witnesses.
