Claims.

This invention relates to car dumping app-aratus for transferring coal or other friable ma.- terial from one car to another or toa suitable receptacle.

One of the prime objects of the invention is to provide a car dumping mechanism for dumping or transferring material from one car into another and in such manner that the material is not dropped or broken, but is gently rolled and discharged in a steady controlled stream so that an absolute minimum of fines and slack is produced.

Another object is to provide an intermediate material receiving means into which the material is dumped and which is actuated in proper sequence to smoothly and gently deposit the load in a transfer car or receptacle provided for receiving it.

A further object is to provide a car dumper construction of such character that the dumping operation occasions a minimum movement of the load, and consequently minimum amount of breakage.

V A still further object is toprovide simple and practical means for transferring coal or other friable material from one car to another or toi a suitable receptacle which is composed of few parts, all of substantial construction, and which is economical to assemble and operate.

With the above and other objects in View,

the present invention consists in the combination and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportion, and minor details of construction, without departing from the spirit, or sacrificing any of the advantages of the invention.

In the drawings- Fig. l is an end view of our improved car dumper mechanism, the solid lines showing the loaded car in position on the cradle, and the hopper in position on the transfer car, the broken lines showing the position of the loaded car and transfer hopper when discharging into said hop per.

ing the hopper in position for discharging into the transfer car.

Fig. 4 is a. fragmentary sectional view showing the hopper in discharging position in the transfer car.

Fig. 5 is an enlarged fragmentary view illustrating one end of the hopper and one of the conveyers, the hopper being shown in section.

Fig. 6 is a fragmentary detail of the pivoted hopper, the broken lines showing the gates on the one side swung down to permit discharge of the load.

In the handling of coal on other friable material it is essential that the coal or material be controlled during the dumping operation so that it does not fall an appreciable distance, and so that large chunks do not gather momentum and crash into the coal stream or receiving receptacle and thus cause considerable breakage. To eliminate the forming of fines and slack, which command a lower price than does the unbroken material, it is necessary that the discharging or moving material flow and roll in a steady stream, and that the mechanism be so designed and operated that the coal does not drop, but that it gently fiows and rolls from one receptacle or depository into another, and we have, therefore, designed simple, practical, and economical means for controlling the discharging and moving material so that it fiows and rolls as above described, and with a, minimum of movement and breakage.

Referring now more particularly to the drawings in which we have shown one embodiment of our invention, the numeral 8 indicates the fabricated structure or tower of a car dumper of conventional design; this includes a cradle 9 provided with tracks ill adapted to accommodate a conventional car I I in which the material to be transferred is loaded. A side wall l2 forms a part of the cradle, and the car I! is shifted against said wall prior to the elevation and dumping thereof. Spaced apart clamps l3 are pivotally mounted on the cradle 9, and a curtain M is secured thereto and forms a closure for the open top of the car to confine the coal as the car is tilted, a lip section [5 being formed on one edge of the curtain, all as shown and described in an application filed by Ernest W. Taylor under date of May 8, 1933, Serial No. 669,823, and when the car is tilted, this lip section swings outward- 1y (see Fig. 3 of the drawings) to permit the dis charge of the coal, metering and confining the stream so that an even, controlled, and steady fiow is assured.

the coal from the tilted car and then swung down and into the transfer car for depositingthe load therein.

The hopper I8 is formed as clearly shown in Figs. 3, 4, and 6 of the drawings, being substan:

tially V-shaped in cross section, and having an angled lip 20 on the inner edge thereof, gates 2| being provided on the lower end to'permitjithe, discharge of the load when the hopper is lowered to position in the transfer car, and an additional gate 22 is provided onthe inner-edge'to assistin this discharging operation when, the hopper is swung upwardly, and as shownin Fig, 6.

Sheaves 23 are mountedon .bracesw24-which are secured to the outer edge of the hopper to accommodate the rope systemzused for controlling the swinging thereof, and in a manner to be presently described.

A deflector plate 25 forms a part of the superstructure and guides the discharging material into. the hopper as the car is beingtilted, and

a machinery house 26 is provided on the frame,

together with anoperator's house 21 so thatthe operator may be properly located to control the sequence of operation. 1

The equipment is. designed to accommodate and handle either one large capacity car. or two small capacity cars simultaneously, and in order to accommodate the two small capacity cars, the hopper is of greater length than the transfer car,

and we, therefore, provide a conveyer 28at'eachend of the hopper so that as the material is being discharged from the car, these conveyers can be driven, thus conveying the coal from the-end sections to the hoppered center sections 29 of the hopper, and which are provided with the gates 2| and'22 as above described; deflector plates 30 are also provided in each end of the hopper for deflecting the material onto the conveyers. V The mechanism for shifting, clamping, and tilting the car, together with the cable arrangement for raising, etc.'are of conventional design, and it is not deemed necessary to show or to describe them in detail, as this invention is directed to the means for transferring thematerial from the loaded car into the transfer car. The hopper is controlled by rneans ofthe; cables 3|, anchored to the hangers 32, thence leading down and around the sheave 23, thence up and around the sheave 33, thence down and around the sheave 34, and up and over the-sheave 35, and being wound on a winding drum 36 as usual, thence the cable leadsback and over the sheave 31, and counterweights (not shown) are connected thereto.

Inpractice the loaded car is onto the cradle and clamped in position; it is then'carried upwardly in the dumper, and rate. certain predetermined point is tilted, the hopper l8'being swung upwardly and into position to receive the contents-of the car; when thecar is sufliciently tilted, the curtain lip I5" begins to swing down,

and the coal begins to roll and flow in'a steady stream into the hopper, theh'opper then begins to swing downwardly as it fills, until the entire content of the car is deposited in said hopper, and where two small capacity cars are simultaneously handled, the conveyers 21 are operated to carry the coal from the end sections to the hoppered center section.

The empty car now is swung back and is lowered, while the loaded hopper is swung down and into the transfer car, the gates 2| are then swung open so that'the coal flows into the transfer can the hopper is then again swung upwardly so that the coal remains deposited in the transfencar-there has been a minimum movement of the coal, no drops or crushing, and the entire operation has. been smooth and easy.

, It will, of course, be understood that the shape of the hopper and transfer car can be varied as desired, and that any other suitable receptacle :maybe substituted for the transfer car.

Frornthe foregoing description it will be obvious that we have perfected a very simple, practical, substantial and economical material handling apparatus for handling coal and. other friable materials.
