Application filed January 28, 1916. Serial No. 74,918.

To all whom it may concern Be it known that We, WILLIAM E. DoosoN and ELMER E. POWELL, citizens of the United States, residin at Checotah, in the county of McIntosh, gtate of Oklahoma, have invented eertain new and useful Improvements in Automobile Attachments; and we'do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art. to which it appertains to make and use the same.

This invention relates to improvements in attachments for automobiles and particularly to devices for drawing automobiles out of sandy or muddy places, and to assist in drawing automobiles up steep inclines.

The principal object of the invention is to provide a novel and simple device of this character which can be readily applied to the ordinary automobile, and which will be effective for the purpose designed.

Another object is to provide a novel and efficient device of this character which, when attached to an automobile, forms a permanent part thereof and Which can be quickly and easily thrown into and out of operative position for actuation by the engine shaft, of the automobile.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In. the drawing: Figure 1 is a plan view of a portion of an automobile showing our invention applied thereto; Fig. 2 is a front elevation; Fig. 3 is a horizontal section through the device; Fig. 4 is a vertical scotion on the line 4-4 of Fig. 3; Fig. 5 is a vertical section on the line of Fig. 3; Fig. 6 is a sectional view showing the winding drum and shaft tilted to diseuguge the actuating g'ars; Fig, 7 is a vertical longitudinal sectional view through a modified form of the device; and Fig. 8 is a vertical section on the line t$-8 of Fig. 7.

Referring particularly to the accompany ing drawing, 10 represents a casing mounted on any suitable part of the automobile. but in close proximity to the engine shaft 11. On thcpugine shaft is mounted u worm gear 12, the same being adapted to rotate wlth the shaft. 'l lxtcnding longitudinally in the ca iug 10 is a shaft 13, and on this shaft, within the casing is a winding, drmn 1.4, on which is wound a cable 15. One end of the shaft 13 is mounted in a bearing block 13 loosely disposed in an opening in the adjacent end of the casing. Secured to one end of this drum is a pinion 16 which meshes with the pinion 17 mounted on a shaft 18 parallel with and adjacent one end of the drum and this pinion is rigidly connected to and rotatable with a second and larger pinion 19. The drum and pinion 16 areloosely mounted on the shaft 13, and rigidly mounted on the shaft 13 outwardly of the pinion 16, and meshing with the pinion 19 is a smaller pin.- ion 20. Thus the rotation of the shaft 13 communicates motion to the drum from the gear 20 to the gears 19 and 17 and back to the gear 16. This arrangement of gears produces a reduction in speed, while at the same time gzeatly increasing the driving power of the shaft 13 on the drum. In the other end of the casing 10 is an opening 21 in which is rotatably mounted ablock- 22 which receives the adjacent end of the shaft 13 eccentrically therethrough. On the lastnamed end of the shaft 13, and outwardly of the casing 10 is a spiral gear 23 which meshes with the before-mentioned wheel 12 carried by the engine shaft.

Mounted on the eccentrically disposed end of the shaft 13 inwardly of the casing and secured to the block 22 is an arm 24 the outer end of which is connected to a shifting lever (not shown) by a rod 25 and by means of which the arm may be moved to rotate the block 22 within the opening 21 for the purpose of shifting the position of the adjacent end of the shaft 13 and thus move its gear 24 toward and away from the gear 12.

In the operation of the device, one end of the cable 15 is drawn to a point in advance of the automobile and secured to a stake driven in the ground, or to a tree, post, or other fixed object. The gears 12 and 23 being engaged by movenu-ut of the arm 24, the engine is started which results in the winding of the cable on this drum 14 and the pulling. of the automobile out of the muddy or sandy place in the road or up a steep incline. As soon as the automobile is out of the undesirable place. the M11124 is shifted back again so as to more the shaft 13 and thus disengage the gears '33 and 12. The cnginc of the automobile is then run to drive the automobile. in the usual manner.

Referring mrticularly to Figs. 7 and 8 there is shown a casing 10', in which is mounted a shaft 13 carrying a drum 14, and on which is wound a cable 15. One end of the shaft 13' is eooentrically mounted in the block 22, said block being arranged in an opening Al in the casing and actuated by a lever 24-. All or these parts are identical in construction to the uorrosponding parts of the other form. 'lhv other end of the shaft 13 is mounted in a Mowing block 13" which is disposed in an polling inthc end of the casing. it wil! in Hullli that in this form of the device the gears Hi 17, 19

and 20 are omitted.

What is claimed is:

An attachment for an automohileooinpris ing a casing mounted on the frame of the automobile adjacent the engine shaft there of, a shaft rotatably mounted in the casing,

a drum rotatably mounted on the shaft pinion carried by the drum and rotatahle therewith, a pinion carried by the shaft and rotatable therewith and disposed adjacent the drum pinion, a pair of rigidly connected and simultaneously rotatable pimons mounted in the casing and each meshing with one of the before-mentioned inions, intergeared connections between the s aft and the engine shaft of the automobile, and an eeeentrieally mounted means for canting the drum shaft 30 to disengage the intergearedeonnections.

In testimony whereof, we aflix our signetures in the presence of two witnesses.
