BREAKING AND FEEDING APPARATUS.

srEeIrIcArreN forming part of Letters Patent at. 617,523, dated January 10, 1899.

Application filed June 9,1898. Serial No. 683,010. (No model.)

T0 at whom it may concern:

Beit known that 1, CHARLES M. DAY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Breaking and Feeding Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.

My invention is an improvement inbreaking and feeding apparatus for coal and substances of a similar nature; and it consists in the novel features hereinafter described, reference being had to the accompanying drawings, which illustrate one form in which I have contemplated embodying my invention, and said invention is fully disclosed in the following description and claims.

Referring to the said drawings, Figure 1 represents a vertical sectional view of the ap- Fig. 2 represents a top plan view of the same. Fig. 3 represents a horizontal transverse sectional View on the line 3 3 of Fig. 1, and Fig. 4 represents a similar view on Fig. 5 is a detail sectional view showing the discharge-aperture and the adjustable controlling-gate therefor.

A represents the shell or casing of the apparatus, which comprises the upper portion or hopper a, provided in this instance with the inclined portion a and the lower cylindrical portion a. The inclined portion may, however, be omitted and the hopper and lower cylindrical portion may be of uniform diameter. In the lower cylindrical portion a is the horizontal bottom plate a which is provided with a central bearing a and below the bottom plate and parallel therewith is the bear in g-plate a provided with a central step-bearing a.

B B represent the breaking-plates, forming an inside cylinder which is secured to the wallsof the casing A, said plates being pro.- vided with a series of breaking-webs of different vertical lengths, as shown in Figs. 1 and 2. The webs I) extend from the top of the breaking-plates nearly to the bottom of the same and are provided at the top withinwardlyprojecting portions b which catch and break I the larger particles. The br king-plates B are also provided intermediat {tlie long webs b with shorter webs b and b as shown in Figs. 1 and 2. Below these webs the cylinder is provided with'a series of horizontal breaking-lugs b 0 represents a vertical shaft mounted in the bearing a and step-bearing a and carrying at its-upper end the breaking-cone C. This cone is provided exteriorly with a series of breaking-webs c c 0 arranged correspondingly to the webs b b 19 the longest webs o being provided with outwardly-projecting portions o in the horizontal plane of the projections b (See Fig. 1.) The cone 0 is provided below the webs with breaking-lugs 0 which alternate withthe lugs 11 on the breaking-plates. The breaking-cone is also provided witha series of downwardly-extending agitating-fingers c D represents a movable bottom located above the bottom plate a of the lower cylindrical casing a and consisting in this instance of a horizontal plate or disk having a central hub secured to the shaft O,'so that the plate shall revolve therewith. This bottom, which has a veryslow movement, receives the material directly from the breaker and keeps it in slow motion around the casing, so as to bring all portions of it to the delivery-aperture and prevent the clogging of the machine, which would otherwise result. provided with a serrated or notched peripheral edge (Z," (see Fig. 3,) and its upper face is provided with a series of webs or 'ribs ct, ex: tending from the periphery toward the center, but not being disposed radially on the disk,

This plate or disk is the said webs being very low adjacent to the periphery'of the disk and increasing in height adjacent to the hub. These webs or ribs are so arranged as to have a tendency to convey the material on the disk or plate toward the periphery. The lower face of the disk or plate D is also provided with cleaning-ribs c C is provided with a worni'wheel C the teeth of which are engaged by a worm E on a driving-shaft E, which is mounted in suitable bearings e and provided with a driving-pulley e. The worm E is preferably incased in a trough (2 provided with a hinged cover 6 \Vhile I have found this to be a very advantageous arrangement for driving the shaft C, it is obvious that I may drive it in other ways if desired.

The part a of the casing A is provided at one side with a deli very-aperture (L7, the lower edge of which extends below the revolving plate or disk D, as shown in Fig. 5, and F represents a delivery chute or spout for conveying the material from the apparatus. The inner edge of this spout F extends within the serrations (Z on the periphery of the disk D, so that any material which is carried around in said serrated edge will fall vertically therefrom into the chute. The delivery of the material through the aperture a is controlled by means of an adjustable gate G, which is pivoted to the part a at g, at one side of the aperture a, said gate being provided with a horizontally-disposed portion or guard G adjacent to the upper edge of the aperture 607. In order to enable the gate G to be maintained in any desired position, I provide it with an adj usting-arm g, the outer end of which extends through a slot g in a stationary arm 9 which is preferably curved concentrically with the point of pivoting g. The said arm g is provided with a shoulder g, which engages the inner side of the arm g and the outer extremity of the arm is threaded and provided with a wing-nut or equivalent device for clamping the arm g to the arm to hold the gate in any position to which 'it may be adjusted. I

The operation of the apparatus is as follows: The material, which may be coal or other material of a similar nature, is placed in the hopper a and will be broken up by the breaking webs and lugs of the breakingplates and the breaking cone as it passes downward into the receptacle a. In the latter receptacle the broken material is kept in motion around the shaft 0 by the revolving bottom D. Portions of the broken material as it moves around within the receptacle ct will be caught by the edges of the adjustable gate G and deflected outwardly into the delivery chute or spout F, by which it is delivered to any desired point. By setting the gate G farther inward toward the shaft 0 a greater amount of material will be fed to the spout and by setting it nearer the wall of the receptacle a the amount allowed to pass to the spout will be decreased. It will thus be seen that the feed of the apparatus can be very accurately regulated by adjusting the swinging gate G in the manner hereinbefore described.

hat I claim, and desire to secure by Letters Patent, is-

1. In a breaking and feeding mechanism,
