CHARLES J. SEYMOUR, OF BROOKLINE, MASSACHUSETTS.

ELEVATOR AND CONVEYER.

SPECIFICATION forming part of Letters Patent No. 423,821, dated March 18, 1890.

Application filed July 27, 1889.

I. To all whom it may concern.-

Be it known that 1, CHARLES J. SEYMOUR, of Brookline, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Elevators and Conveyors, of which the following is a specification.

My invention relates to that class of machines or devices commonly known as elevators and conveyers, being contrivances for raising coal, grain, 860., out of a vessel or other receptacle, conveying it to a particular point, and depositing it in another receptacle.

My invention consists of a conveyer comprising an endless line or chain of pans or the like properly supported and moved and constructed and arranged to be separated at given points, the retreating and returning lines being connected again and adjusted at such separated points, so "as to discharge the coal, grain, or other substanceinto a chute at said points.

My invention also consists of an elevatorhead of novel construction adapted to such elevator-legs, in which the buckets and pans discharge their contents into a chute located between the ascending and descending lines of such buckets and pans. Y

My invention will first be described in connection with the accompanying drawings, forming a part of this specification, and then pointed out in the appended claims.

Of the drawings, Figure 1 is a vertical sectional view designed to show the form and construction of my improved elevator-head, as also the manner in which my improvements are operated to take coal, grain, &c., from one receptacle, elevate it, and convey it to and discharge it into another receptacle. Fig. 2 is a transverse section designed more particularly to illustrate the improved conveying and discharging feature of the device. Fig. 3 is a diagram of a feature of the invention hereinafter more particularly referred to. Fig. 4 is a detail view of the elevator-head on an enlarged scale. Fig. 5 is a detail view show ing the construction of the pans. Figs. 6, 7, and S are detail views showingthe mannerin which the chain of pans maybe parted at any desired points.

The same letters designate the same parts Serial No. 318,909. (No model.)

or features, as the case may be,whereverthey occur.

In the drawings, a designates a receptacle for the transportation or storage of coal, grain, &c'., and Z) another receptacle to which such coal, grain, 850., may be transferred.

0 is an elevator leg or frame at one end of the receptacle a, and d is an endless line or chain of buckets and pans constructed and arranged to travel to and fro the entire length of the receptacle a and receive material therefrom, and then to travel up, over, and down the elevator-leg c, discharging such material at the top of the elevator-leg into a chute e, by which it may be conducted to an endless line f of pans or similar receptacles. This last-mentioned endless line or chain of pans is supported and travels upon suitable tracks 9, and is moved by and around sprocketwheels h h h 7L3, or similar devices, as will be readily understood by reference to Fig. 2 of the drawings.

In order to be able to discharge the contents of the pans of the line f at various points, as is in practice desirable, I have so constructed and arranged said line as that it may be taken apart at given points and the separated ends of the upper lines connected with the like ends of the lower line, passing such shortened endless line over sprocketwheels 71. h or other suitable guides and forming a discharging-point for the pans at the outward extremity of the outward travel of the upper line between the wheels h 72. as indicated at 'i, Fig. 2.

When it is desired to cease discharging the contents of the pans at the point i and discharge the coal, grain, or the like taken from the chute a into the chute j at the point It, the line f passing around the sprocket-wheels h h will be severed at the point where they pass around the last-mentioned wheel by the removal of an axle m between two pans, and the upper and lower lines connected by the replacement of an axle in each, so as to form a continuous upper and lower line from the chute e to the point j, where the upper and lower lines will be disconnected and reunited, so as to travel around the sprocket-wheels h and h as shown.

In Figs. 5, G, 7, and 8 I have shown a construetion whereby the axles on may be removed and the line of pans separated at any point.

To provide for the travel of the endless chain of pans around any of the sprocket wheels on the line, Iconstruct the upper track 9 with hinged or pivoted sections k, which will permit of removing aportion of said track out of the way of the travel of the pans around the sprocket-wheels. Said hinged section of the track I have shown in Fig. 3 as constructed so as to be swung sidewise or outwardly, though said sections 7;. may be made removable, so. as to be taken entirely out, the only thing necessarybeing to get the upper track out of the way, so that the severed upper and lower lines which have been readjusted around the sprocket-wheels may travel therearound unobstructed. By this means the coal or other material in the pans can be discharged at any point of the conveyer-line where a sprocket-wheel or other guide is placed to guide or carry the line of pans around from theupper to the lower track. Said sprocket or guide wheels may be placed at any point or points along the conveyerline, and power may be applied to any one or more of said wheels in order to operate the chain of pans.

Any suitable means may be provided for tightening and loosening the endless line of pans running over the sprocket-wheels.

In order toprovide for the discharge of the buckets and pans carried up the elevator-leg into a chute arranged between the ascending and descending lines of said leg, I have provided an elevator-head of novel construction on the top of said leg, as shown in Fig.1, where the buckets and pans are kept to the line of the circle described by the circumfen ence of a wheel 1 until they are reversed to discharge their load, when they are guided outwardly away from the ascending line on the leg or frame and around the chute c placed bet-ween the two lines, passing inwardly under said chute as near as may be desirable to the ascending line, when they descend on a line parallel or substantially parallel to said ascending line.

Ihe guiding of the line of buckets and pans on the elevator-deg is accomplished by means of the guides or tracks S. (See Fig. 4-.) In this way an efficient contrivance is provided whereby the buckets and pans may be made to discharge their contents between the as eending and descending lines and the elevator-leg so constructed as to occupya minimum amount of space.

It is obvious that changes may be made in the form and arrangement of parts comprising my invention without departing from the nature or spirit thereof.

.llavin g thus explained the nature of my invention and described a way of constructing and using the same, I declare that what I claim is- 1. A conveyor consisting of an endless line of pans, wheels for guiding and driving and tracks for supporting and guidin said endless line of pans, said tracks being made removable at intervals and said line of pans be ing constructed to be severed at said intervals and adjusted to travel around said wheels, as set forth.

9. A conveyor consisting of an endless line of pans, sprocket-wheels arranged at intervals along said line and adapted to engage the same, and chutes arranged at intervals corresponding to intervals at which the sprocket-wheels are arranged, said line of pans being constructed to be severed and united at intervals corresponding to the intervals at which the chutes are arranged, whereby the contents of the pans maybe discharged at different points, as set forth.

3. An elevator-leg adapted to guide ascending and descending lines of buckets, a guidewheel on the upper end of the said elevatorleg, and a chute arranged beneath said guidewheel, the guides for said lines constructed to guide the buckets over the said guide-wheel and chute and to discharge their contents in the latter, then outwardly from the ascending line, and then around the side of the chute and inwardly and downwardly beneath the same, as set forth.

l. An elevatorleg adapted to guide ascendin g and descending lines of buckets and pans, a guidc-whecl on the upper end of said elevatordeg, around which the lines of buckets and pans are adapted to travel, a chute arranged beneath said guide-wheel, and guides or tracks arranged to guide the line of buckets and pans around and beneath said chute and dump their contents in the latter, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 18th day of July, A. D. 1955!.

CHARLES .l. SEYMOUR.
