HOWARD FORREST GOBSUOH, OF COLUMBUS, OHIO.
STONE-ORUSHER.
To all whom it may concern:
Be it known that I, HOWARD F. a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a new and useful Stone-Crusher, of which the following is a specification.
This invention relates to an improvement in rock crushing machines, in which a plurality of movable jaws are employed.
The primary object of said invention is to provide a machine of this character in which the strain will be taken from the supporting frame, therefore, allowing said frame to be made lighter, which is of great importance in crushing devices of the portable type. j
A further object of said invention is to provide a plurality of movable jaws, said jaws being actuated simultaneously, one of said jaws swinging on'a pivot, the other jaw being bodily movable, having motion imparted to it at its upper and lower ends.
With the foregoing and other objects in view which will appear as the nature of the invention is better understood, the same consists in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention. I
In the accompanying drawings: Figure l is a top plan view of the machine; Fig. 2 is a longitudinal section on the line 11 of Fig. 1; Fig. 3 is a side elevation with the truck and fly wheels removed; Fig. 4 is a transverse section on the line 22 of Fig. 1; Fig. 5 is a transverse section on the line 33 of Fig. 1; Fig. 6 is a detail View showing the mechanism for returning the bodily movable jaw; Fig. 7 is a View similar to Fig. 2, the jaws being in their closed position; Fig. 8 is a section taken on the line 8-8 of Fig. 7; and Fig. 9 is a detail perspective view showing a portion of the mechanism illustrated in Fig. 6.
The machine is positioned on a truck which is mounted on wheels 10 and 11 at its rear end, and the wheel 12 at its forward end, said wheels being arranged to support longitudinally disposed beams 13 and 14. To the beams 13 and 14 are secured side plates 15 and 16 by means of bolts 17. A
GORSUCH,
Specification of Letters Patent.
Application filed April 5, 1911.
Patented Sept. 5, 1911. Serial No. 619,147.
Arranged on the shaft 18 is a pitman 28 which is actuated by the cam 29 as the shaft rotates. This pitman extends rearwardly of the machine and may be connected at any of the points 30, 31, 32 to a lever 34, which lever is pivotally supported at the point 35 by the transversely extending shaft 36, the lever and pitman being disposed at the center of the shaft 18. The lever 34 is provided with the re-curved end portion 37 and to this extension is secured a plurality of links 38, 38 and 39. The links 38 and 38 are pivotally supported at the points 38 of the lever 34, the re-curved end portion of said lever throwing said point 38 in advance of the same, the link 39 being pivotally supported at the extreme end of said recurved portion, this pivot point being slightly to the rear of the transverse shaft 36 when the lever 34 is in a vertical position. The links 38 and 38 are secured to the base portion of the jaw 23 and are capable when the shaft is rotated, of imparting a direct thrust to the lower portion of the jaw.
The link 39 extends between the links 38 and 38 and is pivotally connected to the end portion of a cam lever 40 which is illustrated in detail in Figs. 6 and 9. This lever or link 40 consists of the body portion 41, the
bifurcated end portion 42.which receives the end portion of the link 39 and extensions 43, which extensions are provided with trunnions 44, said trunnions connectin the member 41 with drive rods 45, said drlve rods 45 extending rearwardly of the machine, their other ends being secured to trunnions 46 which extend from the upper portion of the jaw 21. The member 41 is formed adjacent its upper end with a cam face 46 which terminates adjacent its lower end in the beveled face 47, the beveled face 47 contacting with a transversely extending rib 48 formed on the rear face of the jaw 23, said rib being rounded to reduce friction. A. plurality of trunnions 49 extend from the end portions of said rib, said trunnions extending within the elongated slots 50 of the links 51, which links are pivotally supported at points adjacent the upper end of the member 41.
In operation, as the shaft 18 draws the lever 34 to the position shown in Fig. 7 which is slightly forward of the position shown in Fig. 2, said lever will swing on its pivot 36 and by the peculiar curvature of the end portion 37, the links 38 and 38 will be given a forward thrust, particular attention being called to the fact that this is a direct thrust, the bearing 26 facilitating this movement. As the link 34 is driven forward, the member 40 will be forced upward through the medium of the link 39, its cam face on said upward movement contacting with the transverse rib 48 of the aw 23, thus forcing said jaw to the position shown in Fig. 2. This same upward movement carries the recurved end portion of the lever 40 back, thus exerting a pull on the connecting rods 45, this movement swinging the jaw 21 on its pivot and drawing the same toward the aw 23 effectually crushing the rock which is placed within said jaws. It will be noted that by this peculiar action, strain is taken entirely off of the side plates, the jaws and their toggle connections taking all of the force of the crushing action. It will also be noted that the lower portion of the jaw 23 will advance with much greater force than the upper portion, said lower portion traveling in practically a line parallel with the supporting beams, while the upper portion travels in an arc, the peculiar movement of the cam member 41 insuring this arcuate movement. When the shaft has revolved to the position shown in Fig. 2, the jaw 21 will be returned to its normal position through the rearward movement of the connecting rods 45. It will be seen that when the lever 34 assumes the position shown in Fig. 2, the links 38 and 38 will draw the lower end of the jaw 23 forward, its upper end beingbrought to the position shown in Fig. 2 by the links 51 which exert a forward pull on the trunnions 49. Thus, it will be seen that the crushing action is secured without placing undue strain upon the frame or side plates.
What is claimed is 1. In a stone crusher, a pivoted jaw member, a bodily movable jaw member, means for imparting a straight thrust to the lower portion of said second member, means for moving the upperportion of said member in a curved path, andmeans for swinging the first mentioned member on its pivot.
