CHARLES J. SEYMOUR, OF BROOKLINE, MASSACHUSETTS.

ELEVATOR AND CONVEYER'.

SPECIFIGATIdN forming part of Letters Patent No. 404,660, dated June 4, 1889.

Application filed August 20, 1888. Serial No. 283,209. (No model.)

To all whom it may concern.-

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

My invention relates to elevators and conveyers generally, though, as hereinafter described and explained, it has'particular relation to means for unloading coal and the like from boats or vessels.

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

Of said drawings, Figure 1 is a vertical longitudinal section of a vessel, showing the construction and v arrangement of my improved conveyer and elevator in connection therewith and the manner of using the same. Fig. 2 is a crosssection on the line a: as of Fig. 1. Fig. 3 is a diagram illustrating the construction and operation of my improved means for opening and closing the bucket or pan supplying holes in the floor of the vessels hold.

The same letters and figures of reference designate the same parts and features wherever they occur.

In the drawings, a designates the frame of the vessel constructed with a trough or way running longitudinally over the keel beneath the floor of the hold.

I) designates an endless chain of buckets or pans arranged to run over the draft-wheels 2 and 3 and around the idle wheels or pulleys 4 and 5 and over the head 0 on the elevatorframe (Z. Tracing the chain of buckets and pans a from the pulley or wheel 5, they pass up 011 one side of the elevator-frame cl, around draft pulley or wheel 2, over head 0, down on the opposite side of the frame cl, around draft-wheel 3, through the lower part of the chamber, over the keel and beneath the floor, around wheel 4, and back just beneath the floor to and around idle-whee1 5 to the point of starting. The several wheels 2, 3, 4, and 5 are constructed as sprocket-wheels to engage the shafts or other parts or devices of the chain of buckets and pans and carry the same around, thewheels2 and 3 being positively driven, and hence herein called draftwheels, and the wheels 4 5 being idle or guide wheels and operated merely by the movement of the chain of buckets and pans.

The head 0 of the elevator-frame overhangs or projects out from the line of travel of the chain of buckets and pans, so that the coal or other material taken by or delivered to said buckets and pans may, as the latter pass around the overhanging portion of the head, be dumped into the chute 6, while the buckets and pans pass around under the overhangingportion of the head and down again close to the line of ascent, as shown in Fig.1. This construction enables me to economize room to the greatest possible extent in the operation of the chain of pans and buckets.

Itwill be understood, of course, that suitable tracks 25 are provided to guide and support the chain in its movements, the tracks around the overhanging portion of the head down the front of the elevator-frame and under the inwardly-traveling portion of the chain being doublethat is, one over-and one under the wheels on each side.

fdesignates holes or delivering-ports formed in the bottom of the vessel on a line over the line of horizontal travel of the buckets and pans, through which ports the coal or other material is delivered to said buckets and pans. Preferably but one of these ports f (thatnearest the elevator-frame d and capable of delivering coal) will be open'at a time.

With a substantially fiat floor in the hold or apartment where the coal or other article is stored (which construction is necessary to a maximum amount of storage-room) after all of the coal has been delivered to the buckets that gravity will carry down thereinto there will still remain a very considerable amount at the sides of the holes or ports f, and in order to cause this undelivered portion to run or slide into the buckets through the ports I form the floor in movable sections g, hinging the edges of said sections along the line next to the ports f to the frame of the boat or vessel, and leaving the outer portion of each section g so that it can be raised or swung upward, and thus cause the coal or other material thereon to run down into the adjacent port f.

' tioned figure.

In order that no coal on the hinged section g may fall down back of or behind the same as it is raised, and consequently swung inward from the side of the boat or vessel, I hinge a leaf or shelf 71 to the side of the boat above the free edge of the movable section g, with the free edge of the said leaf h resting on the upper surface of said section g, so that as the latter is raised the free edge of the leaf or shelf may be moved outward in eontact therewith, and so prevent the coal from falling behind or under the floor, all of which will be clearly understood by an inspection of Fig. 2, where the full lines represent the position of the parts before the floor is raised, and the dottedlines show such position afterward.

To keep the coal from running down under the floor at the ends of the sections 1, when the latter are raised, I construct partitions 1' between each two adjacent sections, which partitions may extend up to a line a little? higher than the plane to which the sections 9 are raised, as will also be understood by reference to Fig. 2, the ends of the sections g in the raising and lowering of said sections moving in close proximity to said partitions.

The sections g and leaves or shelves 71. may be operated by means of chains or cables j, attached thereto and passing over pulleys 7.1, or be otherwise suitably arranged.

To provide suitable covers or cut-offs to the ports or holes f, whereby the latter may be opened and closed, as may be desired, I pivot or hinge doors 7t at one of their ends, as at Z, to the frame of the vessel, so that said doors may be swung around under the floor and under ports f, and so close or cut off said ports, as shown by dotted lines in Fig. 3, or be swung outward, and so open said ports, as represented by full lines in the last-melt The doors k will at their free ends be guided and supported in their movements by suitable tracks or ways m, and may be operated by means of chains or cables 97. a, secured thereto and passing around pulleys. The swinging movement of the doors It may be limited by suitably-positioned stops q, as shown.

I am aware that sliding doors or cut-offs or covers have been employed in similar connections and for similar purposes on docks, &c., and hence I do not claim the same, broadly.

Either wheel or pulley 2 or 3 may be the driving-wheel, operated from any prime motor, and the other be driven from it by means of a chain or belt, as will be understood by an inspection of Fig. 1.

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

\Vhat I claim is- 1. The combination, with avessel provided with a trough or way beneath the floor and above the keel, of a vertically-arranged elevator-frame at the end of such trough or way, an endless chain of buckets and pans arranged insaid trough or way and on said elevator-frame, and wheels to move and guide said chain, whereby the coal or other contents of the vessel may be taken therefrom and carried directly to and up the elevatorframe to be discharged, as set forth.

The combination, with a vessel provided with a trough or way beneath. the floor and above the keel, of a vertically-arrangod elevator-frame at one end of such trough'or way, said elevator-frame being provided with an overhanging head 0, an endless chain of buckets and pans arranged in said trough or way and on said elevator-frame, and wheels or pulleys and tracks i to move and guide said chain of buckets and pans, as set forth.

3. The combination, with a vessel provided with delivering holes or ports in its floor, of movable sections 9 of the floor, hinged at points at or near said delivering holes or ports, and leaves or shelves 71 hinged to the side of the vessel, with their free edges in contact with said hinged sections of flooring, as set forth.

4c. The combination, with a vessel provided with delivering holes or ports in its Iloor, of movable sections g of the floor, hinged at points at or near said delivering holes or ports, leaves or shelves 7:, hinged at the side of the vessel, with their free edges in contact with said hinged sections of flooring, and partitions 21 between each two sections, as set forth.

5. The combination, with avessel provided with delivering holes or ports in its floor, of covers or cut-offs for said holes or ports, said covers or cut-offs being pivoted beneath the floor and provided with cables, whereby they may be swung around to close the ports or holes, or be moved in the opposite direction to open the same, tracks in beneath the free ends of the corners or cut-cits to support the same, and stops to limit the movementof the covers or cut-offs, as set forth.

In testimony whereof I have sign ed my name to this specification, in the presence of two subscribing witnesses, this 18th day of August, A. D. 1888.

CHARLES J: SEYMOUR.
