PULLING DEVICE.

Specification of Letters Patent. 7

Patented June 19, 1917.

Application filed January 8, 1917; Serial No. 141,310;

To all whom it may concern:

Be it known that I, IVILLIAM J. PAUL, of the town of Grand-View, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Pulling Devices, of which the following is the specification.

The invention relates to improvements in pulling devices, particularly to an article used for drawing automobiles out of ruts or mires, and the object of the invention is to provide an inexpensive and durable appliance which can be readily set up for work and operated by one person and which will effect, when used, the easy pulling of the stalled automobile.

A further object of the invention is to construct the device so that it can be compactly folded up and stored as part of the regular kit of an automobile and further to arrange it so that when folded it will remain so.

WVith the above principal objects in view and certain minor objects, which will be more apparent as the description proceeds, the invention consists essentially in the arrangement and construction of parts here inafter more particularly described and later pointed out in the appended claims, reference being had to the accompanying drawing, in which Figure 1 represents a perspective view of the complete appliance in working position with parts broken awayto expose construction.

Fig. 2 represents a plan view of the article folded up.

Fig. 3 represents an enlarged detailed fragmentary sectional view of one of the yoke bars showing the manner in which the operating handle is detachably secured to the same.

Fig. at represents an enlarged detailed vertical sectional view through the folded yoke bars showing the manner in which the dog alns them.

Fig. 5 represents an enlarged detailed plan view of the end of one of the spindles with the collar and ring thereon.

In the drawing like characters of reference indicate corresponding parts in the seteral figures.

The main or frame part of the device is formed from a pair of yoke shaped bars 1 and 2 which bars have their ends formed into bearings 3, 4, 5 and 6 pivotally mounted ona cross shaft 7 and'are provided more or less centrallyof their length, one with a swiveled eye 8' and the other with an offset 9. The shaft 7 v is supplied atone end with a loop forming a hand grip 10 and carries a split key 11 at the other end which retains the yokes onthe shaft.

The yoke bar 2 is slightly smaller than that 1 and according to the construction it is possible to fold this frame with the yoke bar 2 within that 1 in which position, the eye enters the offset 9. 7

12 represents an operating lever having one end. plugged with a screw 13, which screw is adapted to screw into the central portion of a third smaller yoke bar l4c which has the ends thereof also formed into bearings 15 and 16 mounted on the shaft and within the bearings 5 and 6.

The arrangement of the yoke bar 14 is such that when the handle is unscrewed the said bar can be folded within the yoke bar 2 and' accordingly the device can be folded up to occupy a small space when not in use.

On the shaft and between the ends of the inner yoke bar 14; Imount a drum 17 which has the ends, thereof formed to present ratchet wheels 18 and 19.

On the drum I windacable 20 which carries a pulley 21 and has the end thereof looped back and tied as shown at 22 to the off-set 9.

23 and 24 represent a pair of spring pressed dogs operating on the teeth of the ratchet wheels and slidably mounted on a cross rod: 25 extending between the side arms of the yoke bar 14. l A tube 26 is mounted on the rod to space the dogs. Each dog is supplied with an upstanding spindle 27 which passes slidably through the cross portion of the yoke bar 14 and has the upper end thereof fitted with a ring 28.

On the spindles between the dogs and the yoke bar I mount compression springs 29 which operate to continuously press the dogs against the teeth of the wheels.

30 and 31 are similar collars freely mounted on the upper extremities of the spindles and each provided with a pair of opposing slots 32 and 33 which slots in the normal or engaged positions of the dogs are adapted to receive the rings. This lat ter construction allows me to release and hold the dogs released from the ratchet teeth by first catching the rings and pulling the spindles out to free the rings from the slots and then afterward turning the collars on the spindles so that the rings ride on the ends of the collars and cannot reenter the slots. The advantage of this will be later apparent.

A gravity dog 34: is pivotally attached at 35 to the bar 2 and has the free end thereof formed into a more or less T-shaped catch 36 adapted to normally play on the teeth of the ratchet wheel 18 and arranged to allow the drum to turn in a left hand direction and prevent the turning-of the drum in a right hand direction.

The T-head of the dog (see Fig. 2) extends outwardly over the yoke bar 2 and is fitted with a pair of spaced downwardly extending prong like extensions 37 and 38, the outer .one 37 of which is adapted in the folded position of the yoke bars to enter a slot 39 in the bar 1 and the inner one of which is arranged to pass between the yoke bars 2 and 14, these being spaced apart by a washer 410 appliedon the shaft 7 Joetween the bearings 6 and 15.

To the eye 8 I connect a chain, rope or such like 41. In order to better understand the invention I will now describe the manner inwhich it works assuming that it is utilized to pull a stalled automobile out of a rut.

The yokes are opened up from the folded position as shown in Fig. 2 to the open or working position, as shown in Fig. 1, and the chain or cable 41 is attached to any suitable part of the automobile while the pulley of the cable 20 is anchored in a location considerably in advance of the automobile such as by tying it to a stake. The operator then faces the automobile, catches the hand grip 10 in the left hand and the operating handle 12 in the right hand and then ratchets the operating lever forwardly and backwardly. This action causes the drum to be rotated as it is compelled to turn in the backward swinging of the handle by the action of the dogs 23 and 24; and is held locked against turning by the dog 34 in the forward swing of the handle. As the drum rotates the cable 20 will be wound thereon Copies of this patent may be used the handle is unscrewed and the yokes are folded, one inside the other, to occupy the position shown in Fig. 2.

In this form the appliance takes uplittle room and can be carried as part of the regular equipment. In the folded position it is to be noticed that the dog 34: locksin be tween the yokes, being held by the jamming of the prong like extensions 37 and 38 between the side arms of the yokes.

These extensions serve also to strengthen the dog when it is working as they will act as guides on the side arm of the yoke 2 to prevent any lateral thrust of the dog.

What I claim as my invention is 1. In a device of the class described a two part 'foldable frame, pivots for said parts, a pulling drum carried by said frame, ratchet wheels on said drum, a yoke bar carried by the frame pivots, pawls on said bar co-acting with said ratchets, and means for securing the frame parts and the yoke together.

2. In combination, a two part pivoted foldable frame having cables attached to the opposite ends thereof, a winding drum rotatably mounted in the frame and having one of the cables connected thereto, ratchet wheels at the ends of the drum, a yoke bar spannin the drum and pivotally attached to the rame, spring pressed dogs carried by the yoke bar and engaging the teeth of the ratchet wheels, an operating handle secured to the yoke bar, a dog carried by the frame and engaging one of the ratchet wheels to prevent retrograde turning of the drum and wedge means on one frame part for securing the frame parts and yoke together when in folded position.

Signed at Winnipeg, this 13th day of December, 1916.
