Specification of Letters Patent.

Patented Feb. 29, 191 6.

To all whom it may concern Be it known that I, WILLIAM J. COLE- BOURN, a citizen of the United States, residing at Louisville, in the county of J efferson and State of Kentucky, have invented cerq tain new and useful Improvements in Dumping-Wagons, of which the following is a specification, reference being had therein to the accompanying drawing.

- This invention relates to dumping wagons. The best known type of dumping wagons has downwardly swinging bottom doors closed.

. which they carry.

The principal 0b ect of mv invention is to provide a winding drum of this character with a pawl and ratchet actuating mechanism in which the pawl will be automaticallv moved out of engagement with the ratchet wheel at the end of the winding operation, and will be moved into operative engagement with said wheel when the operu thereof out of engagement with the ratchet ato-r grasps the operating device.

Another obiect of the invention is to p o- '1 vide a yielding detent pawl to hold the the same as applied to one side of the goose-f neck 5 of the body 6 of a dumping wagon with said wheel.

drum against rotation in a reverse direction when the operating pawl has been moved out of engagement therewith, and to pro-ji vide such detent with a tripping lever which may be locked against movement in a direc-gs;

ment of the drum 9 1n a reverse direction. drawing the figure is a perspective view of the forward end of; a dumping wa on showing the application, of a door actuating mechanism showing one;

{i this pawl'is formed with a nose 23 for ention to trip the detent.

In the ac zompanying embodiment of my invention.

bodiment of my invention and have shown which is provided with downwardly swinging bottom doors 7-7; these doors being connected by means of chains 8-8 or other carried by a shaft 10 that is journaled in a frame 5 between the sides of the gooseneck 5.

Winding movement is imparted to the drum 9 preferably by an operating lever 11 which is loose on the shaft 10 adjacent one end thereof. Fixed on the shaft 10 adjacent the lever 11 is a ratchet wheel 12 and a pawl 13- is pivoted intermediate its ends to the lever 11 and has its tail portion weighted, as at 14-, to cause the nose 15 of said pawl to be normally held out of engagement with said ratchet wheel 12. The pawl 13 is preferably moved into operative engagement with the ratchet by the act of the operator in grasping the hand grip on the operating lever 11. To this end a bell crank handle 16 is fulcrumed at its angle, as at 17, adjacent the hand grip of the operating lever. The lateral arm of the handle 16 and the tail of the pawl 13 are pivotally connected by a rod 18. It will thus be observed that when the operator grasps the operating lever 11 he presses the handle 16 in a direction toward the lever and as a result the nose 15 of the pawl is engaged with the ratchet 12. It is also to be noted that upon the release of the handle 16 by the operator the weighted end 14: of the pawl will lift the nose 15 12 and simultaneously return the handle 16 to its initial position.

I Attached to the side of the goose-neck 5 in advance of the ratchet 12 is a plate 19, the rear end of the plate being formed with a laterally extending bearing 20. A suitable detent is provided to prevent the moveand. in the present instance, this detent is in the form of a'pawl :21 which is disposed "within and pivoted intermediate its ends, 'as at 22, to the bearing 20. The rear end of 'gagement with the teeth of the ratchet 12 and the forward end of said pawl is enlarged as at 24:. to form a weighted end to yieldablv hold the nose 23 in engagement hen the nose 23 is in engagement with the ratchet wheel, the wheel, because of the tendency of the drum ,1 suitable: flexibleoonneotionst with; adrum 9mm unwind causes a direct longitudinal pressure upon the detent, and as a result, the beveled end of the nose is wedged between adjacent teeth of the ratchet. This wedging action tends to prevent the pawl from being easily disengaged from the ratchet. Therefore in order to overcome thisv objection, the nose is formed with a break joint as indicated by the numeral 23 this joint permitting the pawl to break before becoming disengaged from the ratchet.

In order to trip the pawl 21 to release the drum 9 and the dumping doors 7 a suitable tripping device is provided and is here shown as a foot lever 25 which is pivotally mounted adjacent its rear end upon a bolt 26, carried by a bracket 27 which extends from the plate 19. The rear or short arm of this lever is disposed under the weighted end 24 of the detent 21 and is correspondingly curved to receive said end 24. The opposite or forward end of this lever eX- tends through a suitable guide 28 which is attached to the side of the goose-neck 5 and terminates in advance of said guide in a laterallv evtending foot piece 29.

' A. suitable locking device is provided to support the weight of the longer end of the lever 25 and to consequently prevent the accidental displacement of the detent 21. This locking device comprises a latch 30 which is pivotally connected at one end. as at 31, to the side of the goose-neck 5. This latch includes a laterally extending hand piece 32 which is arranged to be disposed under the longer arm of the foot lever 25 and to co operate therewith to prevent downward movement of the lever.

In passing over rough roads there is a tendency of the detent 21 to become accidentally disengaged from the ratchet wheel 12. and in order to positively lock this detent against such movement. a locking lever 33 is fulcrumed upon the bolt 26, and this lever is formed with a stop shoulder 34, which is adapted, when the lever is moved rearwardly, to engage over the tail 24 of the detent 21. In this position of the locking lever 33. the shoulder also prevents the tripping device from performing its function of releasing the detent 21.

In operation when it is desired to dump the wagon. the stop shoulder 34 of the lever 33 is first disengaged from the tail 24 of the detent 21 by swinging said lever forwardly, and the locking detent 30 is swung upon its pivot 31 from its engagement with the foot lever 25 by the finger piece 32. The operator then depresses the foot lever 25, and as a result, the shorter arm thereof elevates the tail or weighted end 24 of the detent 21, thereby breaking the joint 23 of said detent and disengaging the nose 23 thereof from the ratchet wheel 12. This permits the drum 9 toreadily revolve and consequently unwind the chains 8. "When it isdesired to close the doors 7 the detent 30 is returned to its locking position with respect to the foot lever 25. The operating leverll is oscillated and, as a result, the ncse 15 of the pawl 13 will alternately engage and ride over the teeth of the ratchet wheel 12, thereby rewinding the drum 9. At the same time the nose 23 of the detent 21 will slide over the teeth of the ratchet 12 and will serve to lock said wheel against reverse rotation when the operating lever 11 is swung rear-v wardly. After the doors 7 have been closed the lever 33 is'moved rearwardly and, as a result, the detent 21 will be securely locked in engagement with the ratchet wheel 12.

While I have shown and described one embodiment of my invention it will be understood that this has been chosen for the purposes of illustration only and that I do not desire to be limited to the details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

Having thus fully described my inven tion, what I claim as new and desire to secure by Letters Patent, is
