Application filed June 18, 1921. Serial No. 478,687.

To all whom it may concern:

Be it known that I, GAETANO Loronnsn, a citizen of the United States, residing at 554C lVest Putnam Avenue, in the town of Greenwich, county of Fairfield, and State of Connecticut, have invented a new and useful Automobile Attachment, of which the fol lowing is a specification.

This invention relates to a Windlass attachment for automobiles and has special reference to an attachment of this character adapted to be secured to the front part of the automobile frame and to be utilized for pulling the automobile out of difiiculties or for pulling another automobile out of its difficulties.

One important object of the invention is to improve the general construction of devices of this character.

A second important object of the invention is to provide an improved device of this character having a novel arrangement of reversible Windlass or drum.

A third important object of the invention is to provide novel means for simultaneous ly reversing the driving direction of a drum and the action'of pawls in their relation to said drum.

A fourth important object of the invention is-to provide a novel arrangement for moving a driven worm wheel into and out of engagement with a worm.

Y'Vith the above and other objects in view, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described,

illustrated in the accompanying drawings,

and specifically claimed.

In the aecompanyingdrawings, like characters'of reference indicate'like parts in the several views, and

Figure 1 is a plan view portion of the apparatus or mechanism forming this invention and showing its relation to the frame of themotor vehicle, the part of the apparatus disclosed being partly in section. Figure'2 is an elevation of the-apparatus used also partly in section.

Figure 3 is a detailed section on the line 3-'3'of Figure 2, the automobile frame being omitted.

Figure 4 is a detailed view of one of the end blocks or castings and its associated parts, the view being taken from the back of said castings.

Figure 5 is a detailed View on the line 5-5 of Figure 2, certain parts being omitted.

In the embodiment of the invention herein disclosed there is provided a pair of end castings 2 and 3 each of which has suitable bolt receiving openings 16 to enable it to be secured to the frame 1 of an automobile or the like; The casting 2 has a. recess or pocket 2 formed therein in which is seated a rocking member .2 pivotally mounted in the pocket by means of pin 25. This rocking member is provided with a boss 24 forming an end bearing for a shaft 22. The casting 3 is provided on its inner face with guideways 3' extending vertically of the casting and having slide 20 mounted there'- in, the slide being normally held raised by means of a spring 28 mounted on a pin 12 projecting upwardly from the bottom of the guideways. In this casting 20 is a pocket 2O similar to the pocket 2 and mounted in this pocketis a tiltingblock 20 the block being mountedon a pin 25 extendin through the pocket. On this block is a boss 21 forming'the other end bearing for the shaft 22.

At 5 is indicated the drive shaftof the automobile and slidable on this drive shaft is a worm i one end of which is threaded ri ht handed as indicated at 4 while the ot or end is threaded left handed as indicated at l. This worm is mounted to revolve with the shaft, being splined thereon by means of a spline 6. The arrangement of'the block 20 is such that when it is in an'elevated positiona worm wheel 23 keyed on the shaft 22 will be lifted clear of the worm but when depressed this worm wheel will engage said worm, the engagement being with one end or the other of the worm accordingly as the worm is positioned along shaft 5. It is to be here noted that the teeth of the worm wheel 23 are so arranged that they may mesh with either the right or left hand worms.

As the shaft 5 is always turned in one direetion by the motor'maehine it will be seen that this arrangement permits motion in either direction of the shaft 22. Onthis shaft 22 is fiXGCl'Zl drum 29 for the reception of a cable out-he like which -may either be led to a stationary object and there secured in order to draw the automobile towards such stationary object or may be secured to a movable object and draw the object toward the automobile.

In order to depress the slide 20 against the action of the spring 28, which normally holds it raised, a rock shaft 15 is journalled on the casting 3 and on one end of this rock shaft is a cam arm 15 which'bears against the top of the slide 20. -On the other end of the rock shaft is an arm 26 which serves as the operating arm for the rock shaft and which may have a suit-able link (not shown) connected thereto for operating the arm from thedrivers seat. With this arrangement motion of the rock arm 26 to the rear forces the slide downward and brings the wormgear into engagement with the worm.

Between the castings 2 and 3 extends a cross bar 14 on which. is provided a pair of bearin 13 having a shaft 10 journaled therein. Projecting forwardly from the shaft 10 is a rock arm 10 which is connected by a linl 8 with a shipper 7 engaging the ends of the worm 4: to move it along the "shaft 5. An arm 11 is also fixed on the shaft 1O and is adapted to be operated from the drivers seat by a link (not shown).

Projecting inwardly from the casting 3 -isa pin 17 whereon is mounted for vertical sliding movement a pawl plate 18 the lower end of this plate engaging around the shaft 22. On this plate are pivoted gravity pawls l9 and 31 which are respectively engagable with ratchet wheels 27 and 30 fixed on the shaft 22. Extending up from the shaft 10 is an arm 10 which is connected to a lift finger 9 extending through the plate 18 and arranged to selectively engage and lift one of the pawls so as to hold the selected pawl from engaging with its ratchet wheel.

t is to be noted that the arrangement of the pawls, ratchet wheels and worms is such that the worm is shifted in accordance with the pawl which is permitted to engage its ratchet so that unwinding of the cable from the drum accidentally is prevented even though the worm wheel be disengaged from the worm. Thus, the shaft 5 revolves in the direction of the arrow in Fig. 1. With the worm screw 4 engaged the worm w1ll be in the position shown in that figure and the shaft 22 will turn in the direction of the arrow on Fig. 5. Under these conditions the shaft and drum will be prevented from turning in the direction opposite to the arrow of Fig. 5 unless the pawl 31 be deliberately lifted. Obviously, movement of the worm screw 4 into worm wheel, engaging positionwill free the pawl 31 and permit engagement of the pawl 19 as well as reverse the movement of the shaft 22.

There has thus been provided a simple and eflicient device of the kind described and for the purposes specified.

It is obvious that minor changes may be made in the form and construction of the invention without departing from the material principles thereof. It is not therefore desired to confine the invention to the exact form herein shown. and described, but it is wished to include all such as properly come within the scope claimed.

Having thus described the invention, what is claimed as new, is
