ROCK-CRUSHER.

Specification of Letters Patent.

Patented Dec. 21, 1915.

Application filed August 18, 1910. Serial No. 577,841.

To all whom it may concern:

Be it known that we, CHARLES G. SIMoNDs and ALBERT E. SMITH, citizens of the United States, residing at Milwaukee, in the county of Milwaukee and State of WVisconsin, have invented a new and useful Rock-Crusher, of which the following is a specification.

The object of our invention is to provide a crusher in which the product is rapidly discharged being assisted in its exit by cen-. trifugal force; to provide an extremely simple and compact machine, and one in which means is provided for readily adjusting the crusher heads to and from each other to compensate for wear and to vary the size of the product.

WVe attain these objects by the mechanism illustrated in the accompanying drawings, in which three embodiments of the invention are shown, which drawings form a part of this specification.

Figure 1 is a vertical longitudinal section of the machine taken along the center line of the crusher shaft; Fig. 2 is a transverse section taken on the line 12 Fig. 1; Fig.

3 shows a transverse section taken on the line 34: Fig. 1 and looking in the direc-' tion of the arrow. Fig. 4B shows a vertical longitudinal section taken along the center line of the crusher shaft of a modified form of the device; Fig. 5 is a transverse section on the line 12 of Fig. 4. Fig. 6 is a central longitudinal and vertical section of a second modification of the device; and Fig.

17 is a transverse section taken on the line 12 of Fig. 6.

The same parts are given the same reference numerals throughout the different views of the drawings.

The machine frame as shown in Fig. 1 consists of two essential parts, a tube like part and a pedestal 51. These parts may be made separate and rigidly secured together or they may be made integral as shown. The tube or barrel 50 carries interiorly an eccentric sleeve 52 which is virtually a part of the frame during operation of the device. This sleeve 52 affords two internal bearings 53 for the shaft 54 which The material to be crushed is fed through the opening to the space between the crusherheads 55 and 58. In this tapering are revolving, centrifugal force will move the material away from the center, and when crushed fine enough to pass through the outlet between the crusher heads, the material will be thrown out and gathered by the trough or hood 61, which covers the opening between the flange 59 and the head 58 and leads to the spout 62, through which the'material is finally discharged.

The eccentric sleeve 52 may be adjusted in the barrel 50 so that its eccentricity will augment or decrease the resultant eccentricity of the crushing heads. This adjustment is for the purpose of giving the heads a greater relative movement when crushing spongy tough material, or a smallerrelative movement with attending greater force when crushing very hard material. The sleeve 52 is secured in its adjusted position by the bolt 63 which may be engagedin any one of the holes 6 in the flange 66 of the sleeve.

The head 58 is adjusted to or from the head 55 to compensate for wear or to materially change-the size of the product, by placing washers of different thickness on the bolts 68. These washers 67 may be U-shaped in order that they may be removed or replaced without entirely removing the head 58 or the bolts 68. In order to make the washers 67 more accessible the top half of the hood 61 is made removable.

It will be noted that'the horizontal component of the crushing strain which, in the machine shown in Fig. 1 is between one half and two thirds of the total amount, is taken on the vertical bearing between 55 and 59, the reacting surfaces of which have only the small relative movement due to the eccentricity of the heads. The vertical component of the crushing strain acts upward on the bearing 65 and. is partly counter balanced by the Weight of 58 and 59.

. The machine as shown in Figs. 4 and 5 does not differ inprinciple or mode of operation from the preceding form, nor does it differ very materially in construction. The

adjustable eccentric sleevelS is placed outside of the frame barrel or tube 11. This arrangement has the trifling disadvantage that as the sleeve 18 is adjusted, the'peripheries of the crusher member and flange 16 will be varied relatively to the hood 27. Also the crusher heads 15 and 19 must overhang the pedestal 10 more than in Fig.v 1 by the thickness of the flange 9.5 on the eccentric sleeve 18. Also'the bearing of the sleeve 18 is not so readily lubricated as in the form shown inl ig; 1. Otherwise the two ployed with the form of crusher heads shown in: Fig. 1. In this form the outer hollow forms are about the: same. I In Figs. 6 and 7 we show a modlfied form of frame and mounting wlth a radically dlf- .ferent form of crushing heads. The mounting shown in Fig. 6 may however be emshaft carries the driving pulley and if the form of heads shown in Fig. 1 were used the outer head would be directly driven.

I The hollow shaftBO has twointernal bearings 32 running on a stationary quill 38, and

one external bearing Bat journaled in the frame bearing The rear end of the, stationary quill-33 is supported in the frame bearing 36*and is prevented from turning.

in the frame by the bolt 37. The crusher shaft 38' has its bearing in the stationary quill, said bearings being parallel with but eccentric to the others. This form of frame, shafting and quill isin some respects preferable to the formshown in Fig. lfrom the fact that the outer sleeveh'a's' amuch larger bearing on the'ecc'entric stationary quill, and with the form .of heads of- Fig. 1 the outer and heavier head would be directly driven leaving'the smaller head-to follow.

The crusher'heads-shown in Figs. 6 and 7 consist of flanges or webs 39 and to, each carrying four inter-engaging lugs. These flanges are carried respectively'by the internal shaft 38 andexternal hollow shaft 30. The lugs (1 a a and a are carried by the internal shaft 38, the web 39, and the hub 41'. The lugs 6 6 b and 6 are carried by the outer shaft 30 and. the web 40. As

these shafts are parallel and eccentric the space between two adjacent lugs, as a and 72 will be at its minimum while the diametrically opposite space,between a and 6 will be at its maximum, and all the spaces around thej arcs between these two will vary.

between these limits. The spaces between the lugs-taper decreasingoutwardly, and centrifugal force will move the material until it is caught and crushed between the lugs to finally escape" to the collecting trough or chute 42 and be delivered thereby through the opening l3 in the base of the frame.
