ROCK-CRUSHER.
SPECIFICATION forming part of Letters Patent. No. 393,440, lated November 27, 1888.
(No model.)
To all whom it may concern;-
Beit known that I, JOEL B. LOW, of the city and county of San Francisco, State of California,have invented an Improvement in Rock- Crushers; and I hereby declare the.- following to be a full, clear, and exact description of the same.
My invention relates to that class of rockcrushers in which the rock is' crushed between opposing jaws; and my invention consists in the constructions and combinations of devices which I shall hereinafter fully describe and claim.
The object of my invention is to provide a simple and effective rock-Crusher which can be easily operated and adjusted to crush the rock to any degree of I'ineness, and which can be readily cleaned in all its parts, making it especially adapted for the use of assayers and for any small work where samples are desired.
Referring to the accompanying drawings for a more complete explanation of myinvention, vFigure l is a vertical section of my rockcrusher, showing tliejaws in working position. Fig. 2 is a side elevation showing the jaws elevated out of the way, the hopper E being removed to permit the jaw B to be raised.
A is the frame ofthe machine, consisting of separated side pieces or standards and a base.
B is the stationary jaw, which is secured at its upper end between the sides or standards of the frame by a bolt, b, and its lower end is held to its place or seat by means of a remov' able pin or bolt, b.
C is the movingjaw, having a long stem or leg, c, extending upwardly between the separated sides of the main frame and provided with a head, c, which iits over the operatingeccentric d ofthe drive-shaft D. This eccentric is located in the central vertical plane of the space between the jaws, so that the lower edges of the two jaws would naturally come in contact. The lower end or working portion of the jaw C opposes the working-surface of the stationary jaw, forming between the two jaws a tapering space, into which the material is fed by means of a small removable hopper or chute, E, let into the side of the frame above the top of the stationary jaw. This space between the jaws is regulated to vary the fineness to which the material is crushed by the following means:
Ivoted to the back of the base ofthe moving jaw atf is an arm, F, the free end of which has a lug,f, to which is pivotcda link, G, the free end of which tits in a slotted or grooved bearing, H, on the inain frame, andis provided with a spring buffer or cushion, g, behind the fixed bearing H, and held or set up by a nut, g', on the end of the link. This is the takeup for the movingjaw, holding its base or operating portion away from the other jaw to permit the discharge of the material and to primarily adjust the space between the jaws.
Threaded through the fixed bearing H is an adjusting screw, I, the end of which bears against the end of the arm F in asmall socket made therein for the purpose. By setting up this screw the moving jaw is pressed closer to the stationary jaw, so as to increase the fineness of the crushing, and by turning the screw back the springbuffer g pulls the jaw outwardly to increase the space between the two jaws and provide for coarser crushing.
Near the top of one side of the frame are made extension lugs or hooks J, which serve the following purpose: By taking out the removable bolt or pin b, which holds the stationaryjaw Bin place,saidjaw may be grasped from behind and turned around on its bolt above, as a pivotal center, to an almost vertical position at the top of the frame, with its face turned outwardly; and in this position it is held by placing the bolt or pin b', which was removed from below, in the extension lugs or hooks J justin front of the jaw. Instead of these lugs for holding the bolt, it is obvious that I might make holes through the frame to receive the bolt, in order to hold thejaw in its elevated position. Now, by running back the adjusting-screw I, so as to free the arm F, the link G may be raised from the slotted or grooved bearing H, and the moving jaw Cmay be turned around on the eccentric d as a center to a position a little beyond the vertical, in which position it rests against the back of the other jaw with its own face outward. It will now be seen that when both jaws are turned to an elevated position their operating-faces are exposed and may be thoroughly cleaned, and the whole interior of the frame and mortar is clear, and may be cleaned out by sweeping Without the least inconvenience.
Having thus described my invention, what I IOO claim as new, and desire to secure by Letters Patent, ism
l. In a rock-Crusher, the frame, the moving jaw pivoted above, and a stationaryjaw opposing said moving jaw, in combination with the take-up for the base of the moving jaw, consisting of the pivoted arm having the lug f', the link connected therewith and having a buier or cushion on its end, a slotted or grooved bearing, into which said link drops, whereby it may be readily released when the moving janr is to be turned to an elevated position out of the way, and the screw bearing against the end of the arm, substantially as herein described.
2. In a roekcrnsher, and in combination with a frame, the stationaryjaw pivoted at its with a frame, a stationary jaw pivoted at its top in said frame, whereby it may be turned up to an elevated position, a removable pin or bolt for holding the jaw in a working position and in an elevated position, a moving jaw in the frame, and a driving-eccentric tted in the head oi' the moving jaw for operating it, and on which said jaw may be turned to an elevated position to rest against the other jaw,substan tially as and for the purpose herein described. 4. In a 1oekorusher, the frame having on one side the lugs or hooks J, in combination with the stationary jaw pivoted at its top in the frame and adapted to be turned up to an elevated position, as described, the removable bolt or pin passing through the frame behind the jaw to hold it in its working position, and adapted to be placed in the lugs or hooks Jin front ofsaid jaw to hold it in its elevated position, and the pivoted moving jaw adapted to be turned up to an velevated position and rest against the other jaw, substantially as and for the purpose herein described.
In witness whereof I have hereunto set my hand.
