GEORGE' W. RAWSON, 0F CAMBRIDGEPORT, ASSIGNOR TO HIMSELF ANI) MICHAEL HIIITINGER. OF SOMERVILLE, -MASSAGHUSETTS Letters Patent No. 95,836, dated October 12, 1869.
IMPRUVEMENT IN STONE-CRUSHING- MACHINES.
The Schedule referred to in these Letters Patent and making part of the same.
To all persons to whom these presents may come:
Be it known that I, GEORGE W. RAWSON, of Gambridgeport, of the county of Middlessex, and State4 of Massachusetts, have made a new and useful invention, having reference to Machines for Crushing Stone; and I do hereby declare the saine to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure l is a top view Figure 2, a longitudinal section; and
Figure 3, a side elevation of' my improved stonecrusher.
Figure 4 is a transverse section, taken through its crushing-month or between the jaws thereof.
The machine, like that of Eli W. Blake, as described in his patent, No. 20,542, has a movable and a stationary jaw, the movable jaw being provided with mechanism for operating it. To this much I make no claim.
I have arranged therewith a surplus-receiver, and other mechanical devices, as hereinafter explained.
'lhe surplus-receiver is to receive the material to be crushed to feed it 'to the crushing-mouth, and to catch or retain, and reconvey to the month any surplus which may be forced upwardfout of the said month by the movable jaw while in operation. The said receiver, also, by its arrangement with the mouth or jaw-chamber, and the stationary and lateral jawplates, serves as a cap to the said plates, and a means of holding them in position when resting on the feet or projections which support them.
In the drawings- A denotes the frame of the machine;
B, its stationary jaw-plate; and
G, the movable jaw-plate.
D is the mouth or space between the said plates it'being provided on its sides by two lateral. stationary jaw-plates, E E. l
Each ofthe aforesaid jaw-plates is to be madepot iron, with its active face cast against a chill-plate.
,Thel stationary plates B E'E rest on ears, shelves, or studs, a a a, projecting from, or making part of the frame A, and, after being arranged within such frame, in manner as represented, such plates, B E E, are to be capped by the surplus-receiver F.
This receiver, formed as represented, is to be bolted or otherwise fastened on the top of the frame, so as to partially surround the top of the crushing-mondi or the entrance thereof.
The surplus-receiver is open at its rear endto enable the' movable jaw to be moved between the side plates E E, both toward and away from the stationary jaw-plate B. v
The latter plate rests against an abutment, Gr, comprising part of the frame A.
vBy interposing one or more thin plates or wedges of metal between the jaw-plate B, and the abutment G, we can vary the distance of the jaw-plate from the movable plate C, so as to vary the width of the crushing-mouth or narrow space between the jawplates when the plate C is at the extreme of its advance toward the plate B.
The said plate C is sustained by a carrier, H, which, at its lower part, is pivoted to the frame A, and at its upper part is hinged to a pitinan, I.
At its rear end the said pitman encompasses an eccentric, K, carried by a driving-shaft, L, on which is fixed a driving-wheel, M, and a ily-wheel, N.
Furthermore, the plate C rests on feet or brackets, et a', extended from the carrier H, and snch plate is further held in place by means of two edge-keys, b b, which go through corresponding holes, c e, 1nade through the carrier.
Each of such keys is furnished with a screw, (I, and a nut, e, arranged with it and the carrier, in manner as represented. By setting up the nuts, the keys will be drawn into their holes, and forceddown upon the upperinclined surface of the plate C, so as, with the brackets a a, to act to rmly hold the plate to the carrier.
By revolving the driving-shaft areciprocating vibratory motion will be imparted to the carrier and its jaw-plate C, whereby stones, when 'between the said jaw-plate and theplate B, will be crushed by them.
Each of the said last-mentioned jaw-plates has teeth or corrugations projecting from its linner face, e e, but the lateral jaw-plates or mouth-plates EE are without any teeth.
As the jaws and the lateral boundaries ot'the crnshing-rnouth are liable, while in use, to become worn, l
they are so constructed las-to be readily removable from the frame, in order that, when injured, or too much worn, others may bel substituted for them.
The surplus-receiver F, by catching any stone which may be forced upward ont of the 4mouth D, and by holding a large amount of stone, and feeding it into the mouth as fast as it will receive it, saves much labor and attention, which would otherwise have to be bestowed on the machine inthe way of feeding it with stone, and returning to it such as may be ejected from the mouth in an upward direction.
Inits operation on stones when wit-hin its mouth, the machine vill crush them, and, after they may have been broken to the right size, they will be discharged from between the two jaws,B (l, in a manner well understood by those who use the Blake stone-crushing machine. 4
Machines of this kind are useful for crushing ores, as well as for reducing stone to be employed in making or repairing roads.
I make no claim to a hopper as ordinarily applied them in position when they are resting on the studs to a grinding-mill. or projections a a, by which they are supported.
What I claim as my invention in the stone-crush- 2. Also, the arrangement of the Wedge -keys b b, ing machine, as hereinbefore described, is as follows; and their screws d d, and nuts e e, with the jaw C, that is to sayand its carrier H, applied together as set forth.
l. The arrangement of the surplus-receiver F, with GEO. W. RAWSON. the stationary and lateral jaw-plates B E E, as de- Witnesses: 4 scribed, Viz, so as to extend over, and serve as a R. H. EDDY,
l cap to such plates, and a means of aiding in holding S. N. PIPER..
