GRAIN-CONVEYER.

SPECIFICATION forming pm of Letters Patent No. 286,764, dated october 1e, 1883.

Application filed August 2S, 1283. (No model.)

To all 1,071,011?, t may concern: I

Be it known that I, FRANK BIERCE, of Chicago, in the county of Cook and State of Illinois, have invented certain new and usefulV Improvements in Grain Conveyers or Transferrers; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the artto which it appertains to make and use the same, reference being .had to the accompanying drawings, and to the letters of be -ioaded My present invention relates to anovel construction of the transfer-car employed in this operation, whereby a more speedy action vis insured, space and material economized, and a more satisfactory and eflicacious result realized. Y

rIhe advantages of my invention are hereinafter set forth in detail, and the particular features of novelty pointed out in the claims.

In the drawings, Figure 1, Sheet l, represents a perspective view of my improved car, a portion being broken away to` show the internal disposition of parts. Fig. 2, Sheet l, represents a similar `view of a modied form of the same, and shows the position of the weighing device. Fig. 3, Sheet 2, is a crosssectional view of the'two box-cars on separate tracks with an intermediate transfer-car containing my improvements. Fig/1, Sheet 3, is a like view, showing modications in the construction of the transfer-car. Fig. 5 is an end view of the transfer-car, and Fig. 6 a crosssection showing a modification. Figs. 7 .and

8 are detail views of the grain-elevator. Fig. 9 shows another means of transferring grain, in which the grain is first elevated from the car to be emptied intoabin or receptacle,then

weighed, and again elevatedto be elnptied into a removable spout or trough, from which it is conveyed to the car or vessel to be loaded.

The body of the transfer-car is constructed in the main like that of the ordinary box freight-car, which it exceeds in height to a greater or less extent, dependent upon the size and arrangement of the elevating devices within. Preferably near the end of the car is situated a subjacent box, A, extending as near the track as safety will permit. This box contains the elevator-housing, and directly above it the car is provided with a gate, vBfor the admission of the delivery-chute C from the car to be unloaded. The gate, box, and elevator may, if desired, be situated at some other point in the length of the transfer-car, as illustrated in Fig. 2. Ihe steamimotor D, for operating lthe elevator, is situated at the end of the car, as shown. A belt from the fly-wheel of the motor drives the upper line of shafting,which imparts motion to elevator, to which the wheel F is attached. At the lower end of the elevator is placedthe idler G, supported in suitable bearings. Both wheels are provided with projecting blades or sprockets H, which are so spaced as to bear successively during their revolution upon the upper surface of the disks or blocks I, fixed upon the rope or chain K. A series of these wheels and idlers is mounted upon the upper and lower shafts, respectively,'each being Vfurnished with a separate rope and elevating disks or blocks, and having a common feed. Notable advantages accrue from the use of this series. upon the working parts is more evenly dis tributed, the breakage of one of the ropes does not interfere with the continued operation of the` others, and the upper receiving-spout, M,

in the forni of a chute.

The strain IOO To the bottom of the bin is attached a rope, l?, depending from an overhead pulley, Q, and operated by a winch, B, as shown in Fig. 4, or by other suitable means.

To the side of the car is attached the runway XV, by which the bin O is guided upon being elevated, assuming at different points the positions shown in dotted lines in the drawings. The hinged roof-secti on S is drawn up out of the way of the bin in its last position, where it discharges its contents by means of chute T into the car X. The weighing device L, preferably a Fairbanks scale, may be placed beneath the bin, as illustrated in Fig. 2.

In Fig. l the bin O is provided with an inclined bottom, resting upon strong frame-work for support. The lower left-hand side of the bin is provided with a gate, Z, which is opened to discharge the contents when the bin is elevated. The roof-piece S is pivoted, before remarked, so as to swing out of the track of the rising bin. In the form shown in Fig. (i the bin is of such a form as to accommodate itself very nearly to the shape of the roof when discharging its contents.

The discharge-valve is provided with asprin catch, V, which is automatically tripped by a projecting pin when the bin has reached its upper position. The three modications shown, while differing in detail, have these generic features in common: first, they are vertically adjustable in the car, so that after being completely filled they may be raised and discharged at once; secondly, they rest, while being filled, upon the bottom of the car, from which circumstance the height of the elevator, and consequently of the caritself, is materially lessened; thirdly, the walls or roof of the car are hinged, so as to permit the upwardly-moving and adjustable bin to assume the best possible position for discharging its contents.

A represents the car from which (in Fig. 9) the'grain or material is to be taken, and A2 the car which it is desired to load.

CL is the transfer apparatus,provided at one side, within, with elevator B2.

Cl is a chute extending from the top of the elevator ont to or through the side of the apparatus. A part of this chute adjacent to the elevator acts as a trap or valve, and is adapted to be raised, thus forming a passage through to the bin below, its position when up being shown in dotted lines. A valve, 5, is located in the spout, through which the grain passes to be elevated after having been directed to the bin and weighed. This operation is as follows: The grain is rst elevated from the car, and, by opening the trap or valve in chute C2, the said grain or material is directed to the bin below,where it is weighed and again elevated, 6o the said valve being closed. It is thus directed by the chute to the receiving car or vessel.

Having thus described my invention, what I claim is- Y 1. In a car for the transfer of grain,wei ghi ng mechanism, in combination with a verticallyadjustable bin, substantially as described.

2. In a car for the transfer of grain, weighing mechanism, in combination with a bin and means foiuraising and tilting it, substantially 7o as described.A

3. In a car for the transfer, or transfer and weighing, of grain, the combination ofthe bin with the hinged car-sections S, for permitting it to assume the proper position for discharge.

4. The combination of the bin O, rope l?, and pulley Q with the guideway XV and chute T, substantially as described.

5. In a car for the transfer, or transfer and weighing, o f grain, the combination of the ele- 8o vating device, the chute M, the adjustable bin O, and the discharge-chute T, substantially as described.

(i. In a transfer, or transfer and weighing, car, the combination ofthe upper chute, M, a 8 5 series of elevating devices feeding along its length,with an elevating-bin, substantially as described.

' 7. The combination` in a transfer-car, of the elevating device with a transfer bin provided with a valved spout at its lower end, and a valved or movable trough or chute for conveying the grain from the hopper or elevating device to the car to be loaded, or to other vessel, substantially as herein described.

In testimony that I claim Athe foregoing as my own I affix my signature in presence of two witnesses.
