SEECIFIGATION forming part of Letters Patent No. 686,123, dated November 5, 1901.

Original application filed August 1900, Serial No. 26.907. Divided and this application filed November 12, 1900- Serial No. 36,308- (No model.) 7

To all whom it may concern:

Be it known that I, GEORGE \V. PACKER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illi- 5 nois, have invented certain new and useful Improvements in Conveyors, of which the following is a specification, the same being a division of my application, Serial No. 26,907, filed August 15, 1900.

The object of this invention is to construct a conveyer and its correlative parts so as to enable the material or articles carried by the conveyer to be deposited at any point in the length of the trough or receiver without any i 5 trouble or inconvenience and without interfering with the travel and operation of the conveyer-belt and its flights and to improve the construction of the trough or receiver in which the conveyer travels.

The invention consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawings illustrating the invention the conveyer and its cooperating parts are shown in connection with other appliances for use in handling, cleaning, and distributing castings, and such showing is merely for the purpose of properly illustrating the con struction and operation of the conveyor and 0 its applied and coacting devices.

In the drawings, Figure l is a top or plan view showing in dotted lines the main tumbler or separating-cylinder for operation with castings and the packing used in annealing 5 castings, the elevators for the castings and the packing and the endless carrier constituting the essence of the present invention, and showing also the chutes or droppingspouts for depositing the castings in the in- 0 ner tumblers or tumbling-barrels, the figure being a broken one. Fig. 2 is a side elevation showing the floors of a building with the main tumbler or separatingcylinder, the packing-conveyer apron or belt, and the final 5 tumblers or tumbling-barrels on one floor,

the elevator from the main tumbler or separating-cylinder to the conveyer of the present invention on the second floor for handling the castings, the elevator for the packing from the lower floor to the upper floor of the castings from the packing.

with the conveyer in the present invention for operating 011 the packing, and showing also the hoppers and spouts for the fine par ticlesand (lust of the packing and for the coarse packing and the annealing-pot made up in sections with the fluid-pressure cylinder for handling the pots, the figure being a broken one; Fig. 3, a sectional elevation of the three floors, showing the elevator and delivery-spout for the packingin elevation and 6c the conveyer of the present invention in cross-section for use with the packing and showing also the hopper receiving the packing; Fig. 4, a detail in section of the connection for the packing-discharge spouts with their hopper; Fig. 5, a detail, being a plan view of a portion of the trough or receiver in which the conveyer operates or travels; and Fig. 6, a detail, beinga bottom View showing two sections ordivisions of the trough or receiver in which the conveyer operates or travels.

, The arrangement in which the construction of conveyer and its applied or coacting parts or devices operate is one employing a delivcry hopper or spout A, having an opening or passage or, which is in communication with the receiving end of a main tumbler or separating-cylinder B, having, as shown, encircling lugs or rings b around its body, which travel on rollers 79, mounted on a frame B,

.so that the main tumbler or separating-cylinder can be revolved to produce a separation The separated castings discharge at the delivery end of-the main tumbler or separating-cylinder onto an endless elevator or conveyer C, provided with straight cleats, buckets, or flights c and operating in a suitable frame or support C, which endless conveyer carries castings up for dischargeinto a delivery trough or spout D, havinga downward and outward inclined bottom and a side board or piece d to prevent the castings from falling over the edge of the trough or spout and insure the 5 delivery of the castings to an endless conveyer E, for which purpose the delivery end of the trough or spout D is located above and extends over a trough frame or support F, within which or between the side pieces of which is located a trough or receiver F for the operation or travel of the endless conveyer E, and, as shown, the trough frame or support has its side pieces mounted on uprights or standards f, extending up from the floor or support immediately beneath the endless conveyer, as shown in Figs. 1 and 2. The endless conveyer E runs in a trough or receiver F and, as shown, is in the form of a cable-rope or round belt having thereon disk or button flights or buckets e at regular intervals apart, by means of which the castings or other articles or material deposited in the trough or receiver are carried along to be removed or discharged, as hereinafter described..

The cable-rope or belt of the endless conveyer E runs over pulleys or carrying-wheels E, one at each end of the conveyer. Each wheel E is mounted on a shaft E supported in suitable journal-boxes on standards or posts E The two wheels are of corresponding construction. Each wheel has an outer rim connected with its center or hub by spokes or arms, and the rim is divided into sections by openings e, into which openings the disks or buttons e successively enter as the wheel is rotated to drive or move the conveyer.

The arrangement shown provides for the removal or discharge of the castings or other articles or material to be deposited into a delivery chute or spout G, each having a cover g, so that by raising the cover of a chute or spout the castings or other articles or material can be delivered or depositedthereinto, and in the case of castings the delivery chutes or spouts are each located over a tumbling barrel or cylinder H, mounted on a common shaft H, each having at one end a drivingpulley H and mounted in suitable standards or uprights 1-1 and each tumbling barrel or cylinder has around its circumference a ring" or band h, which contacts with a friction driving roller or pulley h on the driving-shaft 7L2 for rotating the barrel or cylinder for the final operation of cleaning the castings.-

The packing separated from the castings by the action of the main tumbler or separatingcylinder drops onto an endless conveyer I,

mounted upon cylinders or driving-rollers on.

shafts I, supported in journal boxes or bearings on the frame of the main tumbler or separating-cylinder. The loose packing deposited on the conveyer I is transmitted from the delivery end of the conveyer onto the upper face of an endless traveling belt or conveyer J, having on each side retaining-boards j, and from the traveling belt or conveyer J the loose packing is delivered into position to be caught or received by the buckets k of an elevator-conveyer K, running between the side pieces of the support or frame K, by which buckets the loose packing is carried to a point for discharge into a delivery spout or trough L, having a downward and inward inclination, as shown in Figs. 2 and 3, with its delivery end in position to discharge the loose packing onto a perforated plate 1, which acts as a sieve by which the fine material and dust is sifted into a hopper L and carried by a discharge-spout L to the pointfor its deposit. The sieve or perforated plate I is located between the sides or walls of an outer frame or support M in the bottom of an inner trough or receiver N. The outer frame or support M carries the trough or receiver N and is supported on posts or uprights 'm and crosspieees m, and extending out from the crosspieces m are posts or uprights m having cross-pieces m which carry the side pieces of an upper frame or support M, in which the conveyer operates or travels on its return movement. The trough or receiverN is made up of sections, each section consisting of a fixed division at and a dropping or hinged division n, and, as shown, each section is provided with ears 91 which when the sections are together interlock and receive a pivot pin or rod 02 which permits the drop-sections n to fall or swing downward on the pivot, as shown by the dotted lines of one section in Fig. 2. The free end of the free section has attached thereto a cord n running over a pulley n and having on its end a weight n, which permits the pivoted or drop section 7% to fall down on its free end, leaving an'opening in the trough or receiver and furnishing a spout for discharging the packing or other articles or material which is being carried by the conveyer. The spout is returned and held in normal position by the cord and weight to form a continuous receiver or trough, except when one section is dropped, and the dropping of each section is permitted by an opening in the sides of the outer frame or support in line with the drop-section.

An endless conveyer 0, having thereon disks or button-flights 0,'similar to the conveyer E, runs in the trough or receiver N and moves the packing or other article or material delivered from the spout L in the trough or receiver N, and in such movement as the packing or other article or material, if of a nature to be sifted and separated, passes over the perforated plate or sieve Z the fine dust and particles will be sifted out and pass into the hopper L and the coarse packing or other article or material will be carried over the perforated plate or sieve to pass through the trough or receiver N until a drop-section n of such receiver-or trough is reached, when the packing or other article or material will be discharged at the opening formed by the drop-section. A cable-rope or belt for the endless conveyer 0 runs over a pulley or wheel 0' at each end. The pulleys or wheels 0 each have a similar construction to the pulleys or wheels E, eachvhaving openings 0' in its rim for the disk or button-flights corresponding to the openings 6 of the rim of the pulleys or wheels E, which openings are arranged for the disks or button-flights to-enter thereinto with the revolving of the wheels and the travel of the endless conveyer.

A hopper P is located beneath each dropsection a of the trough or receiver N, into which hopper when a drop-section is down, as shown by the dotted lines in Fig. 2, for one of the divisions of a section the packing or other article or material will be deposited and from the hopper whatever is deposited therein is discharged through a tube or pipe P, at-

tached at its upper end to the hopper-discharge by a pin or pivot 13 and having in its lower end a valve or shut-off on the end of a stem 19, moved by a handle or lever 19, to open and close the valve, so that when opened the contents of the hopper and the discharge tube or pipe can be withdrawn, as shown, for one of the tubes or pipes in Fig. 2. The pivot of the discharge tube or pipe for each hopper permits the lower end of such tube or pipe to be swung in a straight line, thereby enabling the contents of the hopper to be discharged in a series of receptacles for the contents arranged in line with the path of swingof the discharge end of the hopper tube or pipe.

The drawings show annealing-pots Q and grappler or lifting-tongs R for raising and discharging the sections of the annealing-pots, a fluid-pressure cylinder S for operating the grappler or lifting-tongs, which cylinder is traveled back and forth on a track T, and the fluid-pressure cylinder receives pressure from a pipe U, connecting with a compressed-air reservoir or other source of fluid-pressure spout. The drawings also show an I-beam V and an end of a main frame V, forming a part of an overhead-traveling crane. None of these devices Q, R, S, T, U, and V form a part of the present invention, and therefore are not herein fully described, as the invention pertains solely to the construction and operation of the conveyer and its correlating and cooperating devices and appliances, and the parts shown in the drawings and herein described are merely for the purpose of illustrating a construction and arrangement of an apparatus in connection with which the con veyer will operate.

Although the trough or receiver F is shown without drop-divisions of a section, it is to be understood that such trough or receiver can be formed with drop-divisions in the same manner and operated on the same principle as the drop-divisions for the conveyer trough or receiver N. The conveyer trough or receiver has each drop-division of its section attached at the forward or delivery end, so as to drop at the rear or receiving end, and this manner-of pivoting not only produces a discharge-opening for the packing, but also furnishes a guide or support for contacting the conveyor buttons or flights to have such buttons or flights successively ride up the incline of the dropped division and be guided thereby into a trough or receiver. This is necessary, for if the trough or receiver divisions were dropped reversely a square edge would be furnished,against which the buttons or flights would strike and produce injurious effects. The lowering of the movable or drop division of a section forms a discharge-spout down which the contents of the trough or re ceiver will slide to be deposited upon the floor or into a hopper or other place of deposit for final disposition. The attaching of the discharge-division pivotally at its forward end leaves the other division of each section in a level plane for maintaining the conveyer in its line of travel without interfering with such travel.

It will be understood that while the invention is shown and described in connection with other devices specially pertaining to the handling of annealed castings, the conveyer and its correlating devices are intended for use and can be used in other places and for other purposes where a discharge of the articles or material being operated upon by the conveyeris desired to be at diiferent points between the receiving and delivery ends of the conveyer trough or receiver.

I claim- 1. In an endless conveyer, the combination of a receiver or trough having a drop-division, dropping in the direction of its receiving end and forming when dropped a discharge-opening in the receiver or trough, an inclined guide for the endless conveyer, and an endless conveyer operating in the receiver or trough to move the material therein from its point of reception for discharge at the opening formed by the dropped division, substantially as described. 2. In an endless conveyer, the combination of a receiver or trough for the carrying of material, having at the point of reception for the material a perforated plate or sieve and having in its length a drop-division, dropping in the direction of its receiving end and an endless conveyer operating in the receiver or trough to move the material therein from the point of reception to first pass over the per forated plate or sieve and separate dust and fine particles from the material, and to then discharge the material at the opening formed by the dropped division, substantially as described.

3. In an endless conveyer, the combination of a receiver or trough for the carrying of material, having at the point of reception for the material a perforated plate or sieve and having throughout its length drop-divisions,each dropping in the direction of its receiving end, an endless conveyer operating in the receiver or trough to move the material therein from its point of reception to first pass over the perforated plate or sieve and separate dust and fine particles from the material, and to then discharge the material at an opening formed by a dropped division, a hopper for the fine particles and dust, and a series of hoppers, one for each drop-division, receiving the material thereinto from the opening formed by the dropped division, substantially as described.

4. In an endless conveyer, the combination of a receiver or trough consisting of a series of fixed and drop divisions, each drop-division pivoted at its forward or delivery end to the fixed division and dropping in the direction of its receiving end to form when dropped an incline for guiding and directing the buttons or flights of the conveyer and a discharge-spout for the trough or receiver, substantially as described.

5. In an endless conveyer, the combination of a receiver or trough consisting of sections, each section having a fixed division and a drop-division, the two divisions united one to the other at their abutting ends by ears and a pivoting-pin, permitting the drop-section to fall in the direction of its receiving end and furnish an opening in the receiver or trough for the discharge of material carried forward in the receiver or trough, substantiallyas described.

6. In an endless con veyer, the combination of a receiver or trough consisting of sections, each section having a fixed division and a drop division, the two divisions united at their abutting ends one to the other by ears and a pivot or pin permitting the drop-section to fall in the direction of its receiving end and furnish an opening in the receiver or trough for the discharge of material carried forward in the receiver or trough, a cord or rope attached to the free end of each drop-division, and a Weighton the cord operating to raise the drop-division into its closed position, substantiall y as described.
