CBUSHING-MACHINE.

Specification of Letters Patent.

Patented Aug. 5,1913.

Original application filed January 26, 1910, Serial No. 540,119. Divided and this application filed April 1,

To all whom it ma concern:

. Be it known t at I, EDGAR B. SYMONS, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a certain new and useful'lmprovement in Crushing- Machines, of which the following is a specification. My invention, which is a divisional application based on the subject matter divided 540,119 filed January 26, 1910, has for one 1 object to provide new and improved means for fastening a crushing disk to a disk crusher as illustrated diagrammatically in one form in the accompanying drawmg,

- "Lilfifiarts are. indicated by like letters -.throughout the several figures. 25 v The spherical crusher head A, which is mounted on the shaft A carries the dish shaped crushing member A which is held against the backing A by the holding screw A which screw is provided with the conical head A in engagement with the conically apertured collar A rigidly held in central position in the disk A The collar A is provided about its periph- 'ery adjacent its upper side with'the flange A; This flange overlies a flange A, which projects inwardly from the crushing disk A on its inner side thus' forming a halved joint between the disk and the collar. The pressure may thus be exerted upon the collar to draw the disk against this seat without exerting any separating force upon the disk and any flowing of the metal of the disk which would'tend to constrict t-he'size of the aperture in which the collar is located will merely exert a pressure force upon the collar and exert no tendency toward throwing it out as would he the case if the engaging surfaces were inclined. Moreover the fact that the plane between "th llar A and plate A is normal to the 'lini of pressure between them prevents the possibility of any wedging action which would tend to distort the plane or collar by forcing one into the other. The screw A is in engagement with the screw thread A on the inside of the pocket A in the crusher head. The

pocket A is provided with the lugs B which project into the holes B in the base of the pocket A and compress the spiral springs B to force the plate outwardly. The plate B is provided with the teeth 13* in opposition to the teeth 13 on the end of the screw A and has the lug B projecting upwardly beyond said teeth. The screw A is provided with the centrally disposed polygonal pocket C in which is located the squared end C of the screw C which is screw-threaded in the center of the screw A and is in opposition at its lower end to the lug B.

It will be evident that, while I have shown in my drawing an operative device, still many changes might be made both in size, shape and arrangement of parts without departing materially from the spirit of my invention. I have illustrated my whole means as applied to a disk crusher having a disk shaped crushing disk and it will at once be evident that, while this device is primarily intended for use in such connection where the ordinary lock, nuts, bolts,

be used for a large number of situations and I wish therefore my drawings to be regarded in a sense diagrammatic.

The use andoperation of my invention are as follows: It will be understood that the crushing disk will preferably be made of some tough or ductile material such as manganese steel which flows readily when great pressures are brought to bear upon it and this fiowage will under ordinary circumstances have a tendency to constrict the material about any centrally disposed holding means and lock it imposition and I provide, therefore, a centrally disposed washer of some other material which is designed to take up and resist such flowing and locking tendency. Any such material as is suited for a crushing disk will, it is at once evident,' be unsuited for machining. It is thereforenecessary to provide a soft metal backing which may be poured between the disk and the head to form a foundation for the crushing disk at all points. In [assembling my device the inner screw located within the main holding screw is first screwed in. The locked diskis placed in the pocket in such manner that the lugs thereon extend into the holes projecting therefrom and rest against the spiral spr1ngs. The d1sk 1s then put in place and the holding screw mserted through it and screwed into the pocket n 5 the crushing head. The inner screw Wlll rest against the lug project-mg upwardly from the locking plate and hold 1t. away from the end of the screw so as to keep the teeth out of register one with the other. When the holding screw has been tightened down into position in such manner that the conical head is pressed tightly agalnst the conical surface in the washer the central screw is then screwed out sutiiciently to enable the teeth on the locking disk to engage the teeth on the end of the screw thus holding the screw firmly in posltlon and preventing its working out and releasing the disk.

I have stated that the flow of the metal in the crushing disk will have a tendency to constrict the central hole and this is likely to occur when the crushing forces are distributed pretty well over the surface of the disk, but if it happens that the crushing is localized about the periphery of the disk, there is a possibility that the extension which there takes place will be taken up by the metal and notpermitted to reach the central hole, but if this occurs, there will be a tendency for the disk to flatten out and great pressure will then be exerted, tending to raise the center of the disk, and this pressure will under some circumstances be so great as in itself to cause a washer cent-rally disposed on the disk to grip the holding bolt. In view of the fact that this collar may be machined and made smooth and even, this tendency toward gripping ofthe holding bolt is of course materially minimized.
