MACHINERY FOR BREAKING COAL.-

Specification of Letters Patent No. 27,191, dated February 14, 1860.

To all whom it may concern:

Be it known that I, ISAAC P. LYKENS, of Pottsville, Schuylkill county, Pennsylvania, have invented certain new and useful Improvements in Apparatus for Breaking Coal; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.

My invention relates to that class of coal breakers in which spiked plates raised by suitable gearing and allowed to fall by their own weight, are used, in connection with stationary spikes, and my improvements consist, firstly, in reciprocating spiked plate and stationary spiked bars combined with chutes having movable doors, the whole be ing arranged and operating substantially as described hereafter so that the proper amount of coal may be submitted to the combined action of the upper and lower spikes; secondly, in so constructing and arranging both the upper and lower spikes and the bars to which they are attached that both can be readily adjusted to break coal of different sizes; thirdly, in certain springs described hereafter and so situated in respect to the upper and lower spikes and their bars as to prevent the latter from coming too close together and so as to ease the violence of any shock which the absence of the proper amount of coal on the lower spikes might cause.

In order to enable others to make and use my invention, I will now proceed to describe its construction and operation.

On reference to the accompanying drawing which forms a part of this specificationFigure 1, is a sectional elevation of my improved coal breaker. Fig. 2, a transverse sectional elevation on the line 1 2, Fig. 1. Fig. 3, a sectional plan on the line 3, 1, Fig. 1.

Similar letters refer to similar parts throughout the several views.

The framework of the machine consists of the four diagonal beams A, secured at the bottom to the frame B and connected together at the top by beams O O which are secured to beams D D, to which are framed the beams E, E. This framework is boarded at the sides and ends so as to form alarge box vertical on the opposite ends as seen in Fig. 1, and inclined outward toward the top on the opposite sides, as seen in Fig. 2.

In suitable boxes on the beams O C and D D, turns a shaft F, to which are secured the segmental cog wheels G G, the teeth of each of the latter gearing into the teeth of a vertical rod H. To the end of each rod is secured a plate I, and to the under side of the latter are connected a series of bars J, furnished with spikes e e. The spikes are bolted to the bars independently of each other, the upper ends of the spikes passing through oblong slots in the bars, and being furnished with nuts on loosening which the spikes may be adjusted nearer to or farther from each other at pleasure. The bars are also so secured to the plate I that they may be moved toward and from each other. Above this plate are inclined shields Z) Z) for a purpose described hereafter. On the opposite sides of the plate are slides 0 0 adapted to girders K which form a part of the general framework of the machine. Each rod H is also guided by a bracket h secured to the beam C so that the teeth of the bar may gear into those of the wheel G as the latter revolves. A beam L is secured to the girders K and a similar beam to the opposite girders K and on these beams are secured springs M so situated that when the bars H with their spiked plates I are down, each plate shall rest on two of the springs.

To the base A are secured a series of bars N, each bar being furnished with a number of spikes n n the bars and spikes being so constructed that the position of the latter on the former may be altered at pleasure and the bars themselves being so secured to the base that they can be adjusted on the same.

On each end of the frame is an opening m (Fig. 1) communicating with a chute Q down which the lumps of coal to be broken pass into the box. To each chute is hinged a door q connected by a rod S to one arm of the bell crank lever t which is hung to the frame and the short arm of which is operated by a slidin rod u the latter being actuated by a cam I one of which is secured to each end of the shaft F, so that as the latter makes one entire revolution,both doors 9 will be raised and lowered once.

The size of the pieces into which the coal has to be broken being first determined upon, the spikes upon the plate I as well as those upon the base B are adjusted by sliding the spikes themselves as well as the bars to such a position that the pieces of coal broken by the combined action of the upper and lower spikes will be of the desired size, the adjustment being such that the upper spikes shall coincide with the space between the lower spikes and vice-Versa. The teeth of the two cog wheels G G are cut away at such points that as they revolve, one of the bars H with its spiked plate shall be elevated while the other bar with its spiked plate is at its lowest position. The arms P P are so formed and their appliances for operating the doors g of the chutes so regulated, that when one of the spiked plates I is down the door 9 of the adjacent chute will be raised, and when the spiked plate is elevated the door will be lowered.

As seen in Fig. 1, the lumps of coal are at liberty to roll down the chute Q, on one side of the machine the door of that chute being lowered while the progress of the coal on the opposite chute has been arrested by the elevated door, so that by the time the elevated spiked plate I is about ready to drop there will be a mass of coal on the lower spikes ready to be submitted to the combined action of these spikes and the descending spikes, in the meantime the adjacent spiked plate is gradually raised and when it is clear of the opening as the door of the adjacent chute is lowered and the lumps of coal admitted to the boX directly under the spiked plate, so that the breaking of the lumps of coal is efi'ected first by one and then by the other set of falling spikes,

the broken pieces falling between the bars N N into any suitable receptacle or chute.

The springs M prevent the spiked plates from falling too low, and serve to ease the violence of any shock which the absence of the proper amount of coal on the lower spikes might cause.

The accumulation of coal on the top of the spiked plates is prevented by the inclined shield 19 down which such lumps as may escape from the partially obstructed chutes will roll down onto the lower spikes.

I wish it to be understood that I do not claim broadly the breaking of coal by means of spiked plates falling by their own Weight, nor the use of a spiked grating. But

I claim as my invention and desire to secure by Letters Patent 1. The reciprocating spiked plates I and the spiked bars N, in combination with the chutes Q, and their movable doors 9 the whole being arranged and operating sub stantially as herein set forth.

2. Attachin both the upper and lower spikes independently of each other to the bars in such a manner that the position of the said spikes may be altered at pleasure, the bars themselves being likewise so secured as to admit of ready adjustment in the manner and for the purpose specified.

3. I claim the springs M arranged in respect to the spiked plates I and the spiked bars N, as and for the purpose set forth.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

ISAAC P. LYKENS.
