PULLING DEVICE.

Application filed October 24, 1917. Serial No, 198,353.

To all whom it may concern:

Be it known that I, GEoReE W. KAISER,

a citizen of the United States, residing at Deming, in the county of Luna and State of New Mexico, have invented certain new and useful Improvements in Pulling D vices, of which the following is a specification, reference being had to the accompanying drawings. 7

This invention relates to an improved device for pulling motor vehicles out of mud holes, or sandy places in the road where the vehicle has become stalled.

It is a primary object of my invention to provide a very simple and effective device for the above purpose which can be easily and-quickly applied to the ordinary motor vehicle or removed from its operative po sition when not in use and conveniently packed away ina relatively small space.

It is a more particular object of the invention to provide a vehicle pulling device embodying a frame adapted to be removably mounted upon the vehicle frame and having a drum shaft mounted therein a drum on said shaft to which one end of a cable is attached, said shaft being mounted at one of its ends for vertical movement in the frame, an extension of the motor shaft having'a worm thereon, a worm gear on the drum shaft, and means to coast with the drum shaft and raise or lower the same to en age said gear with the worm or disen- It is a further general object of my inven tion to provide a vehicle pulling device which consists of very few simply and duraw bly constructed parts and which may therefore be produced at relatively small manufacturing cost.

With the above and other objects'in view the invention consists in the improved construction, combination and arrangement of the several parts'as will be hereinafter more fully described and subsequently pointed out in the appended claims.

In the accompanying drawing wherein I have illustrated one practical embodiment of the invention and wherein similar reference characters designate corresponding parts throughout the several views:

Figure 1 is a side elevation of my improved pulling device showing the same in its applied position; and 1 Fig. 2 is a front elevation thereof.

Referring in detail to the drawing 5 e Specification of Letters Patent.

ignates the front vertical bar of aframe, 6 a horizontal supporting bar connected to the lower end of said verticalbar, and 7 the top bar of the frame which is connected to the upper end of the vertical bar f5 and extends at right angles to the bar 6. To the end of this bar 7, the downwardly extending bar 8 V is'secured. V

9 designates the starting shaft which is suitably coupled at. its rear end to the motor shaft and is mounted at its forward end in a bearing 10 on the frame bar 5. A worm 11 is fixed upon the shaft 9. I

In a bearing 12 on the frame bar 8 one end of the drum shaft 13 is journale'd, said shaft having a fleXiblejoint or knuckle 14 therein. This shaft at its other end is mounted forvertical movement in a yoke 15 fixed upon the frame bar 6. 16 designates the drum suitably fixed on the shaft 13 and r to which one end of the pull'cable 17 is at- Upon the drum shaft 13 the worm gear 18 is fixed. The arms of the yoke '15 are slotted and constitute guides for the wedge bar 19 to one end of which a rod or other suitable operating connection 20 is attached,

said rod extending rearwardly to a point ad j acent the drivers seat. The upper inclined edge of the wedge bar 19 coacts with'the bearing for the shaft 13 which is vertically movable in the yoke 15. -One of the lower arms 6 of the frame has its upper face grooved, as shown at 6 which groove is in close position or registration with the guide slots of the arms of the yoke 15, so that the lower edge of'the wedge bar 19' may engage in the groove, to insure guiding the bar 19, when moved in one direction or the other'b'y the operating connection 20. v From the above description, the operation of the device willbe apparent. When the vehicle becomes stalledin amud hole 'or' sandy place in the road, the supporting frame is mounted in operative position by securing the upper end thereof upon the vehicle frame or body by means of the bolts or other suitable fastening elements, it being understood that the shaft 9 is engaged in the bearing 10 on said frame. The cable 17 is then unwound from the drum 16 and suitably secured to a tree stump or other convenient stationary object. The operator now shifts the wedge bar'19 through the medium of the rod 20 so that the movable end of the shaft 13 is forced p a d y in e yoke 15 and the worm gear 18 operatively engaged with the worm 11 on the shaft 9. The motor is then started so that the shaft 13 is rotated and the cable 17 is wound upon the drum 16. As the cable is wound up, it will be wmanifest that the vehicle will be pulled forwardly. After the wheels of the vehicle have in this manner been removed from the mud or sand, the device may be detached-by simply removing the bolts 21, and compactly stored away in the vehicle body. It will thus be seen that I have devised a very simple and effective means for quickly removing a stalled vehicle from the mud or sand. Thus the loss of time and manual labor incident to the attachment of traction devices to the vehicle wheels will be obviated. As the device consists of but few elements which are of simple and durable construction, it will be appreciated that the device is not liable to get out of order and that it may also be produced at relatively small manufacturing cost.

While I have herein shown and described the referred construction and arrangement of the several elements employed, it is to be understood that the same are susceptible of considerable modification and I therefore reserve the, privilege of adopting all such legitimate changes as may be fairly embodied within the spirit and scope of the in vention as claimed.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent is 1. In an automobile extricating device, the combination with the motor driven shaft of the automobile, of a rectangular frame, comprising U-shaped side parts and top bar connecting the upper portions of the side parts, means to secure the upper arms of the U-shaped parts to the frame of the automobile, a starter shaft mounted in a bearing of one of the side parts and coupled axially'to the motor driven shaft, and provided with a worm, a stub shaft mounted in a bearing of one ofthe side parts and provided with a socket, a shaft having one end engaging said socket, extending at right angles to and below the starter shaft, a U-shaped yoke on the lower arm of one of the U-shaped parts, and in which the other end of the last mentioned shaft has a vertical slidable bearing, a drum on the last mentioned shaft, a worm gear 011 the last mentioned shaft, the upper face of the arm of one of the side parts having a groove, the side arms of the yoke hav ing slots, a sliding wedge engaging the groove and the slots and cooperating under the vertically sliding end of the last mentioned shaft, whereby, when the wedge is moved in one direction, the last mentioned shaft may be tilted in its socket, to move the worm gear in mesh with the worm, to impart motion to the drum for winding a cable thereon.

2. In an automobile extricating device, the combination with a rectangular frame mounted upon the frame of the automobile, said frame comprisingsidewise spaced U- shaped side parts, the upper arms of which being fixed to the frame of the automobile, a top bar connecting the upper portions of the side parts, of a starter shaft mounted in a bearing of one of the side parts and having one end coupled to the motor driven shaft of the automobile, a worm on the starter shaft, a shaft arranged below and at right angles to the starter shaft and having one end provided with a fulcruming socket connection with one of the U-shaped side parts, a member on the lower arm of the other side part and provided with guides, the lower arm carrying the member having its upper face grooved in close registered position with the guides, a bearing vertically slidable in said member and receiving the other end of said last mentioned shaft, a wedge operable in the groove and the guide and having an inclined edge camming under the sliding'bearing whereby, when the wedge is moved in one direction, the sliding hearing is raised vertically, so that one end of the last mentioned shaft may tilt upwardly in a direction from its fulcruming socket, so that the worm gear is moved in mesh with the worm, to wind a cable on said drum.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.

enonen w. KAISER.
