CRUSHER.

SPECIFICATION forming part of Letters Patent No. 734,332, dated July 21, 1903.

Application tiled January 14,1902. Serial No. 89,680'. (No model.) I

To all whom it may concern,.-

Be it known that LTIMOTHY EDWARD HUR- LEY, a citizen of the United States, and a resident of Butte, in the county of Silverbow and State of Montana, have invented a new and Improved Crusher, of which the followingis a fnll,clear, and exact description.

This invention relates to improvements in machines for crushing rock and the like; and the object is to provide a crusher with its pitman-bearings of novel construction so arranged that friction will be reduced to a minimum. Other novel features will appear in the general description.

I will describe a Crusher embodying my invention and then point out the novel features in the appendedclaim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation ofa crusher embodying my invention. Fig. 2 isa section on the line :n c of Fig. 3 with a portion of an end plate of the pitnnanhead broken away. Fig. 3 is a section on the line y y of Fig. 1, and Fig. 4 shows an oil carrier or distributer employed.

Referring to the drawings, l designates the frame of the machine, in the forward portion of which is a fixed jaw-back 2 anda fixed jaw-plate 3, these parts *being of the usual construction. The swinging jaw 4has on its front face the usual swing jaw-plate 5, and this jaw 4 is mounted on a shaft 6, having bearingsin uprights 7, formed integrally withV the sides of the frame, andin plates 8, bolted.

to said. uprights 7. It will be noted by the dotted lines in Fig. l that vthe bearingportions in the uprights 7 at the top extend beyond a vertical line drawn through the centerv of the shaft. By this construction the main portion of the pressure or thrust will be borne by the said uprights, thus lessening the pos` sibility of loosening the ing the same.

The pitman 9 has toggle connection lOwith the swinging jaw and toggle connection 1l with the toggle-block 12, engaged by the adjusting-wedge' 13 in the usual manner. To

plates 8 or of breaktake the strain on the ends of the frame,.

bolts 14 are passed through the ends and the side portions of the frame 1, the walls of l these bearings being provided with recesses 16 to receive oil and an oil-ring or waste saturated in oil.

Arranged within the headof the pitlnan are bushings 17 18, which at their outer ends engage against removable plates or rings 19, and attached to the eccentric between the inner ends of the bushings is a collar 20, the purpose of which will be hereinafter described. This collar, it will be noted in Fig. 4, is provided with notches in its periphery. The b ushings 17 and 18-rnay be each made in sections, if desired, and they are held from rotation relatively to the head 2l of the pitman by means of feathers 22. Placed be- -tween the bushings and the eccentric 'are the friction-rollers 23 24, which at their outer ends engage against thexplates or rings 19, and they are prevented from movement toward each other by means of the collar. 20.

On the upper side of the head 2l ils-an oilcnp 25, and ducts26, 27, and 28 lead from this oil-cup through the head, the

ducts

26 and 28 extending, respectively, through the` A bushings 17 and 18, while the center duct 27 discharges into the space between the inner ends of the bushings a-nd over the collar 20. When the machine is in operation, the oil will flow through the

ducts

26 and 28, thoroughly lubricating the rollers, and the oil passing through the duct 27 will fall into the chamber between the bushings, and the oil in the chamber will be carried up andarcund and thoroughly distributed by means of the collar 20. Y

Having thus described my invention, I claim as-new and desire to secure by Letters Patent- In a c rusher, la frame, atixed jaw, a swinging jaw, an eccentric-shaft having bearingsin said frame, a pitman operated by the eccentric-shaft and connected with the swinging jaw, bushings arranged in the pitman-head andv surrounding the eccentric-shaft, removable plates on the sides of the head and engaging the outer ends ofthe bushings, the in-r IOO rames ner ends of the bushings, and duets at opposite sides of the central duct and extending through the said bushings to the rollers, sub- I5 stantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
