Serial No. 681,098.
in the usual or any suitable manner above which 1s mounted a hopper 2 into which various products adapted to be crushed are disposed. This main frame is of elongated type and secured in one end thereof by means of the bolts 3 is a stationary grinding block 4l, the effective face of which has removably secured thereto a metallic face plate 5 and adjustably mounted on the base of the frame l is an elongated plate 6, the one end of which has the upwardly extending flange 7 formed thereon, the purpose of which will be hereinafter and more particularly described.
rAn additional grinding block 8 is provided, the bottom face of which has a substantially semi-circular groove 9 formed therein, which receives the upwardly extending flange portion 7 of the plate 6, said latter flange forming a substantial fulcrum pomt upon which said grinding block 8 may oscillate. This block 8 is disposed in the frame 1 adjacent the effective face of the grinding block 4 so that a slight space remains therebetween into which products from the hopper 2 may be disposed and the effective face of the oscillating grinding block 8 is grooved as shown at 10, the groove therein flaring outwardly and tapering toward the lower edge of the block so as to form a substantial fiat face at that point. An additional metallic face plate 11 is removably secured to the effective grooved face of the block 8, said plate 11 being designed coincident to the outline of the front face of said block, and in order to prevent undue wear on the side faces of the frame and block 8, the wear plates 12 are mounted on the inner faces of the side walls of said frame.
By so oscillatingly mounting the block 8 upon the flange or fulcrum point 7, it will to a conveyer or the like (not shown) through the medium of the chute 13 formed in the base of the frame l.
A cross bar 14 secured to the upper edges of the sides of the frame 1, a slight distance in the rear of the block 8 has secured thereto, one. end of a coil spring 15, the opposite end of said spring being engaged with a stem or stud 16 carried in the upper face of said block 8, whereby said block 8 may be normally held in its ineffective posit-ion. Any preferred means for intermittently forcing said block 8 to its effective position may be provided, but I have shown a particular means which comprises an air hammer 17, which is suspended from the central portion of said cross bar 4 by means of a bolt 18 which engages a ring or band 19 encircling the forward portion of said hammer. This bolt 18 which extends through the cross bar has its free end engaged by a nut, whereby the hammer proper may be adjusted vertically of the main frame, and the forward end of the hammer has slidably mounted therein a tappet 2O which is adapted to contact with the upper central portion of the rear face of said grinding block 8. Extending into the rear end of the hammer 17, is a pipe 21, the outer end of which is engaged with a union 22, said union in turn connecting with an additional pipe which extends to any source of power, and a bolt 23 has oneend thereof also engaged with said union 22, the opposite end of which extends through an opening in the rear wall of the main frame 1. A nut 24 is engaged with the bolt 23 and is adapted to contact with the inner face of the rear wall of said main frame to limit the movement of said hammer with respect to the main frame, which will at the same time permit the adjustment of said hammer longitudinally of said frame. Thus as air or any other means of power is introduced in the hammer proper 17, the tappet 20 will be forced forwardly to correspondingly force the grinding block 8 toward the grinding block 4, thereby crushing and grinding the products therebetween and upon the release of the force upon the tappet 20, the spring 15 will withdraw the block 8 in its position, simultaneously drawing the tappet 20 to its initial position.
The bolt 18 from which the hammer 17 is suspended, is, as stated, adjustably mounted in the cross bar 14, thereby permitting the forward or effective end of the hammer 17 to be adjusted vertically to act upon the grinding block 8 accordingly and, as stated, said hammer is adjustable longitudinally of the frame in view of the adjustability of the plate 6 carryingthe fulcrum point for the grinding block 8. This adjustability of the block 8 is accomplished by providing a bolt 25 which is in engagement with the rear end of the plate 6 and extends through a threaded openingv26 in the rear wall of the frame 1. The head of the bolt 25 which projects beyond the rear wall permits of ready operation of the bolt whereby it will be seen that the plate may be adjusted longitudinally of the frame and correspondingly dispose the fulcrum point 7 nearer to or farther from the stationary block 4.
In practice, products, either ore or grain, are placed in the hopper 2 and allowed to pass to the space between the grinding blocks 4 and 8, which space is increased or decreased, accordingly, as the operator sees fit through the medium of the adjusting bolt 25. The means of power is then set in eperation which will supply intermittent force to the tappet 20, thereby giving an intermittent oscillation to the block 8, it being understood that the spring 15 causes the return of said block to its initial position after being forced forwardly. The backward and forward movement of the upper portion of the block 8 and the up and down movement given to the lower portion thereof through A the particular fulcruming of the same will thoroughly crush and grind the products disposed between the two blocks. been stated that the hammer is adjustable vertically, but this adjustment is quite slight in View of the fact that the main idea of the invention is to strike the grinding block at the upper central portion thereof so that the blows act as a lever in crushing all products below the plane of the hammer and through this particular construction, it will be seen that a great saving of power is had over the ordinary lever construction which strikes in the center of the block and has no fulcrum point. As the products are ground the same pass to the chute 13 from where they may be conveyed to any desired place whatsoever.
This device may be either used for crushing ore or grain, it being understood that, of course, certain changes will be necessary as regards the grinding blocks in the use of this device for the two different purposes, and it will also be understood that while I have particularly shown an air hammer, that any desired form or intermittent power means may be provided for oscillating the grinding blocks.
From the foregoing it will be seen that I have provided a simple, inexpensive and efficient means for carrying out the objects of the invention and while I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the principles of the invention.
Having thus described this invention, what is claimed is 1. In a crushing machine, a movable jaw comprising a body, the effective face of It has which is grooved vertically, said groove flaring outwardly and tapering toward the` 2. In a machine of the class described, aI
movable crushing jaw comprising a body, the effective face of which is provided with a vertical groove, said groove flaring outwardly and tapering toward its lower end to form a substantial flat face on the body at that point, said body being also provided with a transverse channel in the bottom thereof adapted to receive a fulcruin point.
3. In a crushing machine, a frame, a stationary jaw mounted therewithin, a movable jaw, the effective face of which is grooved vertically, said groove fia-ring outwardly and tapering toward its lower end to form a substantial flat face at that point, means to oscillatingly mount said movable aw in the frame, and means for the actuation of said movable aw within the frame.
4l. In a crushing machine, a suitable frame, a stationary jaw mounted therewithin, a
plate adjustably mounted in the base of said frame a movable 'aw nrovided with a channel 1n the bottom thereof to receive an extension of said alate therein said movable I I u l )aw having the effective face thereof grooved vertically, said groove flared and tapered outwardly toward its lower end to form a substantial flat face for the body at that point, and means to oscillate said movable jaw on its fulcrum point.
In testimony whereof I hereunto affix my v signature in the presence of two witnesses.
