Sheet 1 of 2 J IO 8' INVENTOR FIG 2 CECIL A. CUMMINGS I l ROCK PUNCIIER This invention consists of a rectangular metal boxlike structure whose major parts are two spaced and parallel I-beams that extend the full length of the structure. A large disc is mounted on the underside of the lower flange of each I-beam by means of ways" so that the disc can be moved along the underside of the aforesaid boxlike structure. This is done by means of a horizontally disposed hydraulic cylinder of the double acting type. This is a cylinder having a piston from each end of which extends a piston rod to which is connected a cable that extends around a pulley that is located at eachend of the aforesaid structure and then attached to the previously mentioned disc. The disc rotatably supports structure that in turn supports a hydraulic cylinder on each side thereof. The piston rod of each cylinder has its lower end swingably secured to mechanism that supports a large hydraulic cylinder between two members of the last mentioned structure. The piston rod of the last mentioned hydraulic cylinder is supported by a cone-shaped boxlike support that has two pipes, end to end, extending outward from the apex of the support in order to provide support for the piston rod which has its lower end fitted with a replacable bit adapted to push rock or boulders through any rock crusher on which this invention is mounted. An electric hoist canbe mounted on one end of the aforesaid rectangular metal boxlike structure for use in handling large rocks or boulders. This invention is operated by controls located near the controls of the rock crusher whose operator will also operate this rock puncher.

It is the principal object of this invention to provide a rock puncher of the character described that will eliminate the jamming of a rock or stone crusher by dislodging the rocks or even boulders when they are caught in the jaws of the feeder of the crusher.

Another object of this invention is to provide, a rock puncher of the character described that can be mounted on the top of any rock or stone crusher and operated by the operator of the crusher. v

Still anotherobject of this invention is to provide a rock puncher of the character described which is activated by hydraulic'and/or electric mechanism that will hereinafter be described.

Other objects of this invention will appear from time to time in-the course of the reading of this specification and its appended claims.

The invention is illustrated in the three FIGS. of the accompanying drawings wherein:

FIG. 1 is a side view ofthis invention.

FIG. 2 is an enlarged viewof that portion of this invention that is enclosed within the arrowed ellipse and indicated by the number 2 in FIG. 3.

FIG. 3 is asectional view of this invention, taken substantially along line 3-3 of FIG. 1, and viewed in the direction indicated by the arrows.

FIG. 4 is a sectional view of this'invention, taken substantially along line 4-4 of FIG. 1, and viewed in the direction indicated by the arrows.

In the several views of this invention, like parts are indicated by like reference numbers.

The reference number 5 indicates this rock puncher in its entirety.

The puncher consists of a rectangular metal boxlike structure 6 containing two spaced and parallel I-beams 7. The flange 8 ofthe two aforesaid I-beams 7 is machined so that the disc 9, whose upper surface is also machined, can be slidably moved along the full length of the aforesaid boxlike structure 6, as will hereinafter be described. An inverted L-shaped way is welded to the underside ofa plurality of spaced inverted L-shaped gusset plates 11, which are in turn welded or otherwise secured to the upper surface of the aforesaid disc 9, thereby slidably securing the disc to the underside of the aforesaid I-beams 7 since there is a way 10 and its supporting gusset plates 11 on each side ofthe flange 8 of the two I-beams 7. The disc 9 and the yet to be described structure and mechanism which it supports are slidably moved along the underside of the -l-beams 7 and boxlike structure 6 by means of a 1 end of which extends a piston rod. A cable 13 extends from the outer ends of the aforesaid piston rods and around the pulleys 14. There is one pulley at each outer end of the aforesaid l-beams 7 secured to the already mentioned disc 9, thereby providing a means of moving the disc and structure attached thereto longitudinally along the underside of the aforesaid boxlike structure 6 of this invention. The two aforesaid piston rods and the connection of the ends of the cable 13 to the disc 9 are not shown in any of the views of the accompanying drawings for reasons of clarity. Details of construction of the cable and pulleys can be changed to suit the desires of the manufacturer of this rock puncher, if one so wishes. The aforesaid hydraulic cylinder 12 is secured to the underside of two spaced and parallel brackets 15 that are welded or otherwise secured to the upper flange of one of the aforesaid I- beams 7 as is clearly shown in FIGS. I and 3 of the accom:

panying drawings.

A turntable 16, that is the same diameterv as that of the aforesaid disc 9, is located directly under the disc which supports the turntable by means of a plurality of radially spaced U-shaped guides 17 which are welded to the periphery of the disc 9, as one'can readily see by looking at FIG. 2 of the drawings. A flat head bolt 18 passes vertically upward through the center of the aforesaid turntable 16 to which the bolt is welded or otherwise secured. The shank of the bolt passes through both the aforesaid disc 9'and the ball or roller bearing 19 on top of which is screwed nut 20. One end of the arm 21 is secured to the aforesaid bolt 18 while the other end of the same arm is swingably secured to the outer endof the piston of hydraulic cylinder 22, which is supported within the aforesaid boxlike structure 6 by any desired means. The activation of the piston within this lastmentioned hydraulic cylinder wall rotate the aforesaid turntable 16.

Looking now at FIGS. 1 and 3 of the accompanying drawings it will be seen that two spaced and parallel triangular shaped plates 23, each plate of whichhas a rounded apex, is welded or otherwise secured to the underside of the aforesaid turntable 16 for the support of the

hydraulic cylinders

25, 26, and30. Each of the aforesaid plates 23 is braced by two spaced and parallel triangular gusset plates 27, as one can see by looking at the already mentioned FIGS. 1 and 3 of the drawings. The top of the aforesaid

hydraulic cylinders

25 and 26 are hingedly secured to the triangular shaped plates 23 while the outer end of the piston rod of each cylinder is swingably-secured to the outer end of the U-shaped arm 28 that has its inner end secured to one end of pin 29 which is supported by the triangular shaped plate 23 through which the pin passes for-securement to the large hydraulic cylinder 30 that provides the punching power for this invention. It will be seen on looking at FIG. 3 of the accompanying drawings that there are actually two of the aforesaid U-shaped arms 28 and pins 29. One of the Ushaped arms 28 and pins 29 is located on each side of this invention: one of the arms 28 and pins 29 for the hydraulic cylinder 25 and the other of the arms 28 and pins 29 for the hydraulic cylinder 26.

Continuing to look at FIGS. land 3 of the drawings it will be seen that the lower end of the aforesaid large hydraulic cylinder 30 is fitted with a cone-shaped boxlike support 31 for j sleeve 37. The

aforesaid sleeves

35 and 37 provide additional stability and support-for the piston rod 32 as it moves up and down in the dis'lodging of the rocks or boulders when this invention is in operation. The lower end of the aforesaid piston rod 32 is provided with a replacable bit 38 of any desired design.

The way in which this invention of a rock puncher 5 is used will be fully understood by those experienced in the operation of rock crushers since this punch can be mounted on the feeding hopper of any rock crusher in a way that will not interfere with the rocks being fed into the hopper by a conveyor or any other desired means. The aforesaid bit 38 is always above the outside limits of the flail when the crusher is a swinging hammer crusher, and above the maximum limits of the jaws when the crusher is of a type that embodies jaws for the crushing of rocks and/or stones. The five

hydraulic cylinders

12,22, 25, 26 and operate this invention when activated by hydraulic fluid that is fedthrough tubes or pipes to the cylinders from any desired source. The hydraulic tubes or pipes and the controls are not shown in the accompanying drawings nor described in this specification since they are admittedly old in form and no claim is made for the same. The controls for the aforesaid hydraulic cylinders are located within reach ofthc controls of the rock crusher and are manipulated by the operator of the crusher.

The only part ofthis invention of mine that l have not previously mentioned is actually an accessory in the form of an electric hoist which is suitably mounted on a carrier 39 that is located at one end of the aforesaid boxlike structure 6. The supporting mechanism of the hoist can be similar to that illustrated in FIG. 2 of the accompanying drawing for the support of the large hydraulic cylinder 30. The aforesaid hoist can be operated by means of a solenoid switch that is also within reach of the operator of the rock crusher.

This invention is subject to any and all changes in details of construction and/or modifications in so long as the changes and/or modifications fall within the scope and intent of the appended claims. For example, roller or ball bearings can be placed between the lower surface of the disc 9 and the upper surface of the'aforesaid turntable 16 in order to permit less friction between these two parts as the turntable rotates in the operation of this invention. In fact, most, if not all, of the moving parts of this invention can be provided with roller or ball bearings for increased efficiency of this invention. The aforesaid hydraulic cylinder 30 canbe replaced by an airoperated cylinder as can any of the other cylinders in this invention and the invention will still fall within the scope and intent of the appended claims.
