DUMPING-VEHICLE OR SIMILAR APPARATUS.

SPECIFICATION forming part of Letters Patent N0. 789,756, dated May 16, 1905.

Application filed January 10, 1905. Serial No. 240,439.

To all whom, it nuty CON/06777,:

Be it known that I, ALEXANDER Ross PIPER, a citizen of the United States, residing at Brooklyn, Kings county, State of New York, have invented certain new and useful Improvements in Dumping-Vehicles or Similar Apparatus, of which the following is a specification.

The present invention relates to improvements in dumping-vehicles and similar apparatus employed for transporting material, and is particularly applicable to dumpingcars.

The object of the invention is to provide such an apparatus which is especially adapted for use with material that tends to cling to the sides of the receptacle in which it is transported and which cannot be satisfactorily handled in apparatus heretofore proposed.

In particular the invention is intended for use in handling the refuse collected in cities which includes material of all character and which it has heretofore been impossible to expeditiously unload from the vehicles in. which it is transported without the aid of hand implements.

In the accompanying drawings, Figure 1 is an end elevation of a car constructed in accordance with the present invention. Fig. 2 is a side elevation of one-half of the car. Fig. 3 is a transverse sectional view showing phedcar tilted or in position to discharge its Referring to the drawings, it will be seen that the car is mounted on suitable trucks 1, which may be of any desired form and support a main underframe consisting of longitudinally-extending I-beams 2, connected by suitable straps or plates 3, said beams 2 being suitably mounted on the trucks 1 and extending throughout the length of the car. On said underframe is mounted a rocking frame including a plurality of transverselyextending beams 3 said frame being mounted to rock about an axis extending longitudinally of the underframe and being connected to a plurality of shafts 4, mounted in suitable bearings on the underframe. Each of said beams 3 is composed of two metal bars connected by plates 5 6, and in each of said beams near opposite ends thereof are formed slots 7.

' On plates 6 of the beams 3 of the aforesaid rocking frame rest supporting-rollers 8, mounted in suitable bearings carried by a receptacle or body 9. Said bodyis preferably composed entirely of metal and is provided at its sides with outwardly-swinging doors 10 and has its top closed by hinged lids or covers 11. The bearings for the aforesaid supporting-rollers 8 are carried by plates 12, suitably secured to parts of the framework of the body 9, such plates being arranged in pairs on opposite sides of the aforesaid beams 3 of the rocking frame and the members of each pair being connected by a suitable rod or pin 13, extending through the slot 7 in the beam 3. The body 9 is thus secured to the rocking frame so as to move therewith about the longitudinal axis of the shafts 4 and is also adapted to move laterally on the rocking frame in either direction, such lateral sliding movement being limited by the engagement of the pins 13 with the ends of the slots 7. Suitable means are provided for normally preventing such lateral. movement of the body on its rocking frame in either direction. As shown, such means comprise latches 14, pivotally connected to the body 9 and adapted to engage projections 15, extending from the beams 3 of the rocking frame. Such latches are arranged on opposite sides of the beams, and each is provided with a depending projection or trip-piece 16, which when the rocking frame has been turned the desired distance about itslongitudinal axis will contact with a bumper 17 ,secured to the underframe. Such contact of the toe 16 with the bumper 17 will release the latch 15 and permit the body to move or slide on the tilting frame in the direction in which such frame has been rocked.

Supplemental latches are provided for holding the swinging doors 10 in closed position when the body 9 is in non-dumping position. These latches in the embodiment of the invention illustrated each include a relatively long arm 18, the free end of which ex.- tends across and rests on the top of one of and at its end beneath the platform 27 of being constantly in contact with the underframe, the outer door-engaging ends of such latches on the side of the shaft 4 toward which the tilting frame is rocked will be automatically moved from the position where they will engage said doors, so that when the latches 14-are released and the body allowed to move laterally on the tilting frame such doors will offer no obstructionto the free escape of the contents of the body. It will be observed that the construction and arrangement of latches for holding the swinging doors closed is such that said latches are adapted to be automatically. moved about their pivots simultaneously with the rocking of the receptacle-that is, the instant the receptacle commences to rock the latches on the side toward which the load is to bedischarged commence to move toward inoperative-position. By this construction the ini tial momentum of the load due to rocking or tipping the body or. receptacle is not restricted inthe least by the door, and such load can commence to move laterally imme diately the rocking of the receptacle commences. In case the-load is of material whose parts have little cohesion such as gravel, stone ballast, &c.it is very important that the latch be operated immediately on the commencing of the rocking movement of the body, as otherwise the door will be either torn from its fastenings or the equilibrium of the car destroyed and it overturned. As shown in Fig. 3, each door 10 'underframe, said chains extending over suitable guide-wheels 22, mounted at the side of the tilting frame. As shown, the drums 22 are secured to the shaft 23, and on such shaft is loosely mounted a driving-gear 24, with which meshes a gear 25 on a shaft 26. The latter shaft extends throughout the length of the car-section, under whlch it is arranged,

said section is geared to a suitable pinion 28, carried by a shaft mounted in suitable bearin s on said platform.

twill be seen from the drawings that the aforesaid tilting mechanism is duplicated at eachside of the car, and while but one section of the car is shown in the drawings it will be understood that similar means are arranged at the platform end of the other section to operate the mechanism for tilting the receptacle of said section. It will therefore be necessary to describe but one set of operating means. On the same shaft with the pinion 28 are mounted. two ratchets 29 30, with which are adapted to engage spring-pressed pawls 31 32,0arried by an operating-lever 33. It will be seen that the ratchet 29 is of greater width than the ratchet 30, and in addition to the aforesaid pawl 31 a holding-pawl 34 is mounted on one-ofthe bearings of the shaft carrying'said ratchets and adapted to hold such ratchet and pinion 28 connected therewith against movement in a direction-opposite that in which it is turned by the hand-lever 33. The gear 24 is adapted to be connected with the shaft 23, onwhich it is mounted, by a clutch 35, the operating-rod36 for which extends to eachend of thecar and is provided with arms extending upwardly through the latforms 27.

To normal y prevent rocking of the tilting platform, levers 36 are fulcrumed on suitable uprights secured to the platformand underframe on.- opposite sides of the shafts 4.

Each of said levers 36 is adapted to extend beneath the bottom of the body 9 and is locked in position to prevent downward movement of such body, and therefore ofthe tilting frame on which the body is mounted, by a lever 37. The last said lever is normally locked in position to engage the lever 36 by means of a removable pin 38. -When the pins 38 at eitherside of the body are withdrawn, the lever 37 can be rocked into position to disengage the lever 36 and the latter will then offer no obstruction to the downward movement of the body 9 and its sup porting-frame, but will turn freely about its pivot.

The manner of operating the parts above described and some of the advantages possessed thereby may be briefly stated as follows: When the car is loaded and being moved, the parts occupy the positions shown in Fig. 1, where, it will be seen, the pins 13 occupy positions about midway of the slots 7, in which theyv are adapted to move, and the latches 14 are all engaging the pins 15 and holding the body 9 from sidewise movement the car toward which the load is to be discharged to its supporting-shaft. The lever 38 is then actuated to rotate saidshaft 23 and wind thechains 21, connected with the drums 22 thereof, upon such drums, thus drawing the side of the rocking frame over which said chains pass downwardly toward the underframe. During such downward movement, the free ends of the latch-arms 18 resting on the beams 2 of the underframe, the arms 19 of suchlatches are moved away from the doors 10, and thereafter the latches 14 are tripped by contact of their projections 16 with the bumpers 17. When the latter latches are released, the body 9 will move rapidly downward through a distance limited by the pins 13 coming in contact with the ends of the slots 7. To check such downward movement of the body, buffers 39 may be provided on the rocking frame, said buffers extending into the path of the plates 12, which support the rolls 8. It will be seen that the downward movement of the body will be suddenly checked by its contact with said buffers and theends of the slots 7, which will impart a jar or blow to the load that assists materially in discharging it from the receptacle or body 9. When the body is emptied, the previously-engaged gear 24 is disconnected by operating the clutch-rod 36, and the corresponding gear at the other side of the frame being connected the tilting frame and body will be returned to their normal horizontal position by actuating the other hand-lever, 33.

Preferably there are two of the bodies 9 on each car, Fig. 2, as aforesaid, illustrating but one-half or section of such a car, and each of said bodies is preferably divided into two compartments, as shown in the drawings.

In the foregoing description there is described and the drawings illustrate one embodiment of the present invention, which has been found very satisfactory for the purpose stated. It is evident, however, that the invention may be embodied in various other forms and that the embodiment thereof selected for illustration may be modified without departing from or sacrificing the advantages of the invention.
