WINDING MECHANISM FOR DUIVIPING-WAGONS.

Specification of Letters Patent.

Patented J an. 14, 1913.

Application filed February 18, 1911. Serial No. 609,481.

To all wlwm it may concern Be it known that I, WILLIAM E. SHER- woon, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Winding Mechanism for Dumping-lNagons, of which the following is a specification.

This invention has for its object the production of a particularly simple and etlicient winding mechanism for closing the dumping doors or sections of dumping wagons, cars and other dumping apparatus; and the invention consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure l is a longitudinal sectional View of a dumping wagon embodying one form of my invention, the running gear being omitted, and the intermediate portion of the wagon boX being broken away. Fig. 2 is a sectional view through the winding drums and contiguous parts. Figs. 3 and l are sectional views, looking in opposite directions, on a plane extending between the ratchet wheels on the drums. Figs. 5 and 6 are detail views in elevation and plan, respectively, of the holding pawls and contiguous parts, one of the pawls being omitted in Fig. 5.

This winding or operating mechanism for dumping doors comprises, generally, two winding drums, actuating means for wind ing both drums together, and one drum independently of the other, means for holding the drums from retrograde movement, and means for releasing the holding means.

1 is the boX or hopper of the body of a dumping wagon provided with my invention, said body also including a neck 2 which supports the winding or operating mechanism to be described.

3 is one of two dumping doors or sections forming the bottom of the hopper or box 1; and 4 is one of two chains extending under the doors 3 respectively and winding on the drums presently described.

5 and 6, are respectively, winding drums usually coaXially arranged, the drum 6 being here shown as a sleeve rotatable on the drum 5 which is supported at its ends in bearings 7 supported by the opposite sides of the I neck 2 of the body of the wagon.

The operating means for winding the drums 5, 6 comprises toothed members mounted, respectively, on said drums 5, 6 and arranged contiguous to each other, and a driving or actuating element having means common to both of such toothed members, and operable to actuate one of such toothed members and the drum associated therewith after the chain 4: connected to the other of said drums has been wound up. The toothed members are here shown as ratchet wheels 8, 9 mounted respectively on the drums 5, 6; and the actuating element comprises a lever having a pawl for engaging the teeth of either of the ratchet Wheels 8, 9, and shiftable out of engagement with one of such ratchet wheels into engagement with the other. My winding apparatus is also provided with means whereby the motion of one of the drums 5 or 6 is transmitted to the other during the winding operation, in order that both drums may be wound together, such connection being preferably a lost-mo tion connection, in order that one of the drums will be initially rotated in advance of the other before the rotation of the drums, together as one body begins, and thus will close one door in advance of the other. Such lost-motion also permits additional rotation of-the drum whose actuation has been delayed, the additional rotation closing the other door. In the illustrated embodiment of my invention, such lost-motion connection is provided for by forming one of the ratchet wheels as 8 with a hub extended toward the other of such wheels and formed at its outer end with a shoulder or tooth 10; and by forming the other ratchet wheel 9 with an annular recess into which said shoulder 10 projects, and with an internal shoulder or tooth 11, the shoulders or teeth 10 and 11 projecting into each others path so that one will engage the other after one drum has made at most nearly, a complete revolution. After said shoulders 10 and 11 have engaged, both ratchet wheels 8, 9 and consequently the drums 5, 6 will rotate as a unit. However any other form of lost-motion connection may be used.

In the illustrated embodiment of my invention the operating element comprises an oscillating lever 12 extending between the ratchet wheels 8, 9 and mounted on the hub of the wheel 8, and a hand lever 13 pivoted between its ends at 14 to the lever 12 on a pivot arranged with its axis extending crosswise of the axis of the ratchet wheels 8, 9 and the drums 5, 6. The hand lever 13 carries a rigid pawl tooth 15 at its lower end for coacting with either of the ratchet.

wheels 8, 9 and is shiftable on its pivot 14 for carrying the pawl tooth 15 laterally out of engagement with either of the ratchet wheels 8, 9 into engagement with the other. The hand lever 13 is guided in its movement and held from tilting too far on its pivot, by suitable means 16 carried by the lever 12 near the pawl 15 of the hand lever 13.

In the illustrated embodiment of my invention the lever 12 is formed with a slotted bearing 17, Fig. 3, on the hub of the ratchet wheel 8, the slot 18 of such bearing extending lengthwise of the lever 12 and being of greater length than the diameter of the hub of the ratchet wheel 8 for permitting endwise or rectilinear movement of the lever 12 and parts associated therewith for the purpose of carrying the pawl tooth 1 5 out of engagement with the ratchet wheels 8 and 9 during the rearward movement of the lever 12. One of the levers 12, 13 of the operating element, here shown as the lever 13 is also formed with a rigid catch 19 cooperating with a shoulder 20 fixed to the neck 2 of the body of the wagon for holding the operating element with the pawl tooth 15 out of position to be engaged by the wheels 8, 9 during the unwinding of the drums 5, 6 when the load is being dumped.

The constructions whereby the rectilinear or endwise movement of the operating ele ment is effected for the purpose of releasing said element from the ratchet wheels 8, 9 and for permitting the pawl 15 to ratchet during backward movement of the levers 12, 13, form no part of this invention but form the subject-matter of my pending application Sr. No. 609,482, filed Feb. 18, 1911.

The drums 5, 6 are held from retrograde movement by pawls 21, 22 pivoted at 23 to the short arm of a lever 24 pivoted at 25 between its endsto the neck 2 of the wagon body, the longer arm of such lever being engaged by a catch or trip lever .26 pivoted at 27 and having a pedal 28 by means of which it is operated to release the lever 24. The catch 26 is also formed wit-h an arm 29 for engaging the longer arm of the lever 24 and raising the same during the tripping movement of the catch 26. The parts 21, 24 and p 26 are of substantially the same form as the corresponding parts described in my copending application previously referred to. As in this embodiment of my invention it is intended that the ratchet wheel 8 be first wound, and that after the chain on the drum 5 has been drawn taut the slack remaining in the chain connected to the drum 6 shall be drawn taut by shifting the lever 13 into engagement with the ratchet wheel 9 and winding such ratchet wheel 9 independently of such ratchet wheel 8, the holding pawl 21, which co-acts with the ratchet wheel 8, must be held while the pawl 22 is ratcheting. Consequently, the pawl 21 is held from pivotal movement during the ratcheting thereof over the teeth of the ratchet wheel 8 during the winding of such wheel 8, and the required yielding of such pawl 21 to ratchet is provided for by permitting the lever 24 to move slightly on its pivot 25, such pivotal movement of the lever 24 being usually due to the resilient intermediate portion of the long arm of said lever. The pivot 23 of the pawls 21 and 22 is normally arranged above a straight line passing through the pivot 25 and the point of engagement 30 of the pawls 21 and 22 and the ratchet wheels 8, 9, and is movable below such line during the releasing movement of the lever 24 from the catch 26, so that the pawls 21 and 22 are inefi'ective. The pawl 22 which coacts wit-h the last wound ratchet wheel, that is the ratchet wheel 9, is capable of pivotal ratcheting movement while the pawl 21 is holding the ratchet wheel 8, and in order that the pawl 22 may be returned to its operative position after ratcheting it is provided with a weighted tail 31.

In operation, after the doors 3 have been dropped by operating the pedal 28, they may again be raised to their closed position by moving the lever 12 and parts carried thereby endwisely outwardly disengaging the catch 19 from the shoulder 20, and, after such catch 19 has cleared the shoulder 20, permitting the lever to move in the opposite direction until the pawl tooth 15 engages the ratchet wheel 8. The levers 12 and 13 are then moved rearwardly, said levers moving endwisely as the pawl 15 ratchets over the teeth of the wheel 8 during such rearward movement. At the end of such rearward movement, the pawl drops into one of such teeth and the lever is then moved forwardly actuating the ratchet wheel 8 anddrum 5 secured thereto. By repeating the oscillating movement of the levers 12 and 13, the lost-motion between the drums or the ratchet wheels 8, 9 is taken up, at most at the end of one complete revolution of the ratchet wheel 8, whereupon both ratchet wheels 8, 9 will be actuated as a unit, owing to the engagement of the shoulders 10 and 11 thereof, until the dumping door 3 connected to the first actuated drum, that is the drum 5, has been closed and the door 3 operated by the drum 6 is nearly closed. lVhereupon the lever 13 is moved or shifted on its pivot 14 until the pawl tooth 15 thereof engages with the ratchet wheel 9 and the oscillations of the levers 12 and 13 are continued until the chain 4 winding on the drum 6 connected to the ratchet wheel 9 is drawn taut.
