To all whom. it ntay concern.-

Be it known that I, JEREMIAH CAMP ELL, a citizen of the United States, and a resident of Newton, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement for Breaking or Sizing and Distributing Goal or Similar Substances, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

It is desirable oftentimes to reduce the size of pieces of coal and other substance which are being transferred from a barge or pile, for instance, to the bunker of a vessel or other location; and my invention in part consists in providing a hopper for the reception and the distribution of such coal, as I will hereinafter term the material, with means whereby the size of the larger lumps or pieces of coal may be broken to any desired degree, and which comprises a reciprocating ram or plunger arranged above the outlet tothe hopper and moved vertically toward and from it.

The drawings also show means for simultaneously delivering coal from the hopper in two directions or to two chutes, which is also of my invention, but which forms the subjectmatter of another application.

I will now describe the invention in connection with the drawings forming a part of this specification, wherein Figure 1 is a view in plan of the hopper. Fig. 2 is a view in end elevation thereof. Fig. 3 is a view in side elevation. Fig. 4 is aview principally in verticalcentral section. -Fig. 5 is a detail View, enlarged, in vertical section at a right angle to that shown in Fig. 4:, to illustrate the connection between the hopper and one of the chutes. Figs. 6 and 7 are enlarged detail views of the ram or plunger.

Referring to the drawings, A is the hopper. It has the inclined walls a a a and the perpendicular wall (0 by which the contents of the hopper are caused to be delivered to the outlet a. The sides of the hopper above the outlet form a bed or support for the coal in opposition to the action of the ram and which may be correspondingly strong and heavy.

B is the ram orplunger. It preferably consists of a shank b, forming at one end a vertical slide 6, which is contained and slides in a guideway b on the vertical plate a and which also has a downward-extending pointed extension 5 arranged substantially cen trally with respect to the hopper-outlet a. The ram or plunger also has a threaded hole [1 extending into its shank, into which the threaded end of a piston rod 5 extends. A cylinder 6", attached to the hopper-plate a ,is located over the ram and contains a piston 6 from which the piston-rod extends. The ports of the cylinder are not shown, and any suitable power may be used for reciprocating the piston in the cylinder, and thus reciprocating the ram or plunger toward and from the hopper-outlet. The shape of the working end of the ram or plunger is such as to split the lumps of coal, which lodge at the outlet, into smaller pieces, and the plunger also serves to help in the feeding of the coal by preventing clogging at the entrance of the outlet, even where lumps are small enough to pass it. The plunger or ram may be reciprocated at any speed desired, and it works in the direction in which the coal is moving.

To permit the coal to be delivered from the hopper into two distributingchutes C 0, there is secured to the lower end of the hopper at the outlet a hollow casting D having a single inlet (Z of the size of the outlet to the hopper, from which extend two branches (Z' (Z of the size of the inlet and which end in the outlets (Z (Z Upon'each of these outlets is mounted, in a manner to be turned upon it, a short tubular coupling 6Z5, which preferably is curved longitudinally and which is somewhat larger in diameter than the outlet and is mounted upon the outlet by means of a ring or collar d riveted to the casting at the end of the outlet, a collar (V, which rests upon the said first-named collar and to which the coupling is riveted, and an angle-plate (Z which is riveted to the casting above the couplingcollar. (See Fig. 5.) This provides means for permitting the coupling to turn upon the casting. The chute C is enlarged upon one side at its upper end, where it has a ring 0 to reinforce its upper end. It is attached to the coupling by means of the studs ends of the studs.

connects the chute with the coupling by a pivotal connection, which permits the chute to be swung upon the coupling to vary the position of its outlet. By making the coupling curved, as described, and longer upon one side than the other and by enlarging the chute as indicated it becomes possible to provide the chute with a relatively long range of movement with respect to a short coupling without opening the joint between them. (See Fig. 4:.) It will be understood that each chute may not only be tipped with respect to its coupling, as above indicated, but by turning the coupling upon the casting the direction of the tipping movement may be universal. It will be seen that the legs (Z (Z of the casting are disposed with respect to the inlet d so that the coal passing through the inletis equally divided into two streams, one of which extends through one leg and the chute C and the other through the other leg and the chute C. The operation of the device is as follows: The coal is fed in any desired way to the hopper. The ram or plunger is vertically reciprocated at any desired speed and operates in conjunction with the bed surrounding the outlet to the hopper to break the coal into pieces which will readily pass through the outlet and to also push the coal, whether broken to that size or not, through the outlet. The coal is then divided into two streams and caused to be delivered at the same time into two bunkers or other receptacles, with which the adjustable chutes C C may be connected.

While I have shown the invention as applied to a hopper adapted to simultaneously feed or deliver coal in two directions or by two chutes, I do not confine myself to its use with two chutes, as a third or even a fourth chute may be employed by providing the casting D with one or more additional branches corresponding to the branches d (Z and chutes attached thereto.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1. In a machine for breaking and distributing coal, a hopper the walls of which form a continuous closure with a restricted outlet, a guideway on a wall of said hopper substantially in alinement with said outlet, a reciprocating ram or plunger within said hopper, and arranged to be guided by said guideway to coact with the walls of the hopper to crush the material within the same.

2. In a machine for breaking and distributing coal, a hopper the walls of which form a continuous closure with a restricted outlet, a vertical support within the hopper and at one side of the outlet providing a vertical guideway and means for supporting a cylinder, a slide mounted in said guideway, a cylinder fastened to said support, a ram or plunger mounted upon said slide to coact with the walls of the hopper to crush the material within the same, and a piston in the cylinder connected by the piston-rod with said ram or plunger.

3. In a machine for breaking and distributing coal, a hopper the walls of which form a continuous closure with a restricted outlet, and a plunger or ram having a pointed working end within said hopper and having a reciprocating movement toward and away from said outlet to crush the coal against the walls of the hopper.

4:, In a machine for breaking and distributing coal, a hopper having a restricted outlet and a vertical guideway located within said hopper and at one side of and above said outlet, a slide mounted in said guideway, a ram mounted on said slide over said outlet and means whereby said ram is reciprocated toward and from said outlet as set forth.
