Patented Nov. 11 1930 PATENT OFFICE Loo'MIs KELLY, or SALEM, VIRGINIA MATERiAL-HANDLING APPARATUS Application filed May 4,

I My invention relates to material handling apparatus and more particularlyto appara tus for receiving and conveying away cinders and the like discharged from locomotives.

In apparatus of this. character, the locomotive is usually run over a pit and the cinders and ashesare discharged into a container or bucketdisposed below the locomotive, water being sprayed on to the cinders as they are coliected in the container. The water employed forthis purpose frequentlydischarges into the pit and the principal object of my invention isto provide means for conductingthis excess Water from the pit;

:, Another object of vtheinvention is to provide means for permitting the water em- .ployed for spraying the. cinders to be used over and over again. It

A primary feature of the invention resides in constructing a container or bucket, adapted to be lowered into a pit, to receive material I such as cinders and ashes, and to be thereafter elevated to discharge the material outside of the pit, with means for automatically 2, ;bailing excess water collected in the pit.

A further feature of the invention resides in providing an ash hoist or the like having a pit with a container adapted to be lowered into the pit to receive ashes from the loco- :89. motive and to be thereafter elevated to distainer; the containerhaving means for auto matically bailing excess water collected in the pit, meansbeingemployed for receiving said water from the containerto return it to the reservoir. Other and more specific features residing in advantageous .forms and construction'and relation of parts will hereinafter appear and be pointed out in the claims.

In the drawings, 1 indicates a pit and 2 designates a Wheeled container or bucket, the

latter being adapted to receive material such as oinders, ashes andthe like from a locomotive diagrammatically shown at 3, and to,be thereafter elevated to discharge the material outside of the pit. Any suitable hoist mechanism and hoist frame may be employed for raising and lowering the container 2. In the present instance, the frame consists of a plurality of inclined structural members 4 and 5 which are respectively rigidlyconnected to substantially vertical members 6. Attached to the outersides of the inclined members 5, adjacent their upper ends, are auxiliary structural members 7, the latter being respectively connected by braces or struts 8 to the upper portion of the vertical members 6. Connected to the auxiliary members 7, adjacent their points of attachment to the inclined members 5, are curved arms or members 9 1 alinement with the members 5 and, in

effect, constituting continuations thereof.

The mechanism for raising andlowering the container 2 is diagrammatically represented by the drum39, sheaves tOand the cooperating hoist chain 41, the latter beingattached to the bail. 42 of the container. This bail is preferably pivotallyconnected to arms 43 which are rigid with the container.

The container is provided adjacent three of its corners with pairs of wheels 10, 11 and 12, wheelslO and 11 cooperating with trackways 13 disposed in the pit 1,.the latter thereof. This attachment consists of a pan serving to guide the container substantially horizontally. Upon operating the hoist device, the container is moved along the tracks 13 until wheels 11 and 12 engage with the inclined members 5 on which they are adapted to ride. The wheels 11 are fashioned with outwardly extending auxiliary tread portions 14- adapted to cooperate with the auxiliary inclined members 7 which are disposed outwardly of members 5.

As the container moves upwardly the wheels 12 pass from the inclined members?) and roll along the curved arms 9 and the auxiliary tread portions 1 1 of wheels 11 coact xvith members 7, thereby causing the bucket to tilt and discharge any material contained therein. As shown, the discharged load may be advantageously deposited in a railway car diagrammatically illustrated at 15. r V

A hopper 16 is preferably employed for receiving the Cinders, ashes and the like from the locomotive to guide or conduct them into the container or bucket 2. Adjacent the upper peripheral edge ofthe hopper is a coil 17 hav- 'ng a plurality of openings 18 for permitting water to be sprayed on the cinders as they are deposited in the container. After the container has been filled, it is operated in the manner heretofore described to discharge the einders outside of the pit.

A water reservoir or storage tank 19 is secured by any suitable means such as straps 20, to one of the members 5, blocks being preferably interposed between'the member 5 and the storage tank for spacing the. latter outwardly therefrom. The reservoir is connected to the coil 17 by pipes or conduits 22 provided with a valve 23 for regulating the flow of water. Pipes may be conveniently connected to a valved supply pipe 24: for replenishing the water in the reservoir.

In devices of this character employing water to quench the cinders and ashes considerable trouble has been experienced in disposing of the excess'water which flows into the pit. Expensive installations involving drain pipes have been employed for conducting thiswater away but, due to the fine particles of cinder and'the like, the pipes quickly become clogged. Other devices, such as pumps, steam jets, etc., have also been used to dispose of this excess water but without success. To overcome these dilficulties the bucket or container 2 is provided with 1 an attachment permitting excess water to be bailed from the pit and discharged outside or compartment 25 which is rigidly secured on the underside or bottom of the container as by welding. One side of the pan adjacent its upper edge is formed with a plurality of openings 26 for permitting the excess water collected in the pit to enter the compartment. it will, of course, be appreciated that should level of the Water be below the openings in the pan or compartment'25, as indicated by the line A-A'in Figure 1, when the container is in the pit, water will not enter the compartment but, on the other hand, if water is above the level of the openings in the container it will readily flow therein.

Communicating with the side of the pan, opposite openings 26, is an upwardly extending discharge pipe or conduit 27, the upper portion of the conduit being secured to the container by a strap 28. It will be seen that since the car is maintained in the same relative position when being moved along the trackways 13 and the member 5 as when it is receiving cinders, the water contained in the compartment 25 is prevented from discharging therefrom. When the bucket is tilted to discharge its load into the car 15, the water in the compartment 25 is also discharged.

The water, instead of flowing intothe car,

is deposited into a receiving hopper 29, the

hopper being supported by rods 37 and is so positioned and proportioned that the water will discharge thereinto irrespective of the tilted position assumed by the container. The outer rod37 is provided with sleeves 38 for preventing movement of the hopper 29 longitudinally thereof. -A pipe or conduit 30 connects the hopper 29 with the storage tank or reservoir 19, thus enabling thewater to be used over and over again. As some of the water is carried away by the cinders or ashes the supply of water in the reservoir may be replenished by properly operating valves 24 and 23. An overflow pipe 31 may be advantageously connected to the upper end of the storage tank for discharging back into the pit water in excess of the capacity of the tank; An elongated member 32 is preferably employed for preventing fine particles of cinders from clogging openings 26 of the pan 25 and thus also preventing clogging of other parts of the water system. The member 32 is fashioned with slots 33 registering with the openings 26, the slots 33 communicating with a passage 34. A screen or any suitably perforated member 35 is secured by bolts or clips 36 to the member 32 to prevent particles of cinders from entering the passage, 34, the bolts 36 also serving to connect the member 32 to the bottom of the pan as clearly shown in Figures 5 and 6.

The method herein disclosed for disposing ofthe excess water in the pit is particularly advantageous as the one operation of hoisting the container enables simultaneous disposal of the cinders and water.

Another advantageous feature of this c0nstruction resides in the fact that the bottom of the container is usually submerged in the water in'the pit, thus effectively preventing the hot ashes from warping it and its cent parts.
