Specication of Letters Patent.

Application led December 19, 1908. Serial No. 468,306.

To all .whom it may concern: j

Bc it known that I, EDGAR B. SYMoNs, residing at Milwaukee, inthe county of `Milwaukee and State of Wisconsin, have invented a certain new and useful Crushing-Machine, of which the following is a specification.

My invention relates to improvements in crushing machines' in which the crushing members rotate,`and are given in their rotation a mutually "reciprocative movement, thereby operating to crush stone or other material fed into the cavity between them.

The objects of my invention are, first, so.to improve t-he form of the opposing, crushing members so as to afford to material, during its travel from the mouth to the exit of the crushing cavity,- al continually increasing crushing area, thereby' allowing the material to spread during the process of its reduction; second, to provide for the utilization of centrifugal force in maintaining afeeding pressurewhich shall vary with the speed and working capacitybf the machine; third, to provide for changing the length of the crushing stroke, or reciprocative movement of the opposing crushing members, as maybe necessary or desirable to suit the various requirements or conditions of Work; fourth, to improve the method of taking up the wear of the crushing members, and also of adjusting their position relative to each other in order to change the size of the product; and fifth, to produce a comparatively" light, strong, durable and easily reparable crushing machine,- one especially efficient in `the production of sand, or in the reduction of stone or like material to .small particles.

Other minor objects appear in the description which follows.l

My invention consists of the rotative reciprocative crushing plates or members which form a cavity between them.

It-consists also in the means employed for supporting and rotating said plates; in the" manner ofV determining and maintaining the angleof their respective planes of rotation; in the centrally located feeding orifice in association with the outwardly converging Acrushing cavity and peripheral exit; and

also in the combinations of parts for effecting theobjects desired as .hereinafter specified and'definitely pointed out in the claims.

" In the following description reference is had to the accompanying drawings in which Figure 1 is a sectional plan of. my ma* chine with the feeding spout removed, and taken 'on the line M N of Fig. 2. Fig. 2 is a side elevation of my machine. Fig. 3 is an end elevation having a portion of the `outer casing'broken away to show the cir- `is adjustably secured by threaded attach- Patented J an. 2, 1912.

ment at B. The threaded ring portion of the cap 2, is divided'at C, (see Figs. 4 and 5) and may be clamped securely to the flange A, by means of the bolt 3, and the nut 4, thereby locking together parts 1, and 2, to form the outer rotative shell hereinafter alluded to, and referred to'in the claims. Said outer shell Iis supported by, and is rotative in bearings 5, and 6. The head-end,

yor disk-like portion of cap-2, is connected to said threaded ring portion by the arms 7, between which the openings 8 are provided to allow the escape of the crushed product.

9v is a belt-wheel keyed to shaft 1, for applying power to rotate said shell. Inside the hollow shaft l, is mounted the shaft 10, whichhas its bowl-shaped end.D,'seated i by ball and socket joint 11, in fiange A. The outer end of shaft 10, is carried by the bearing 12, which is supported by and made laterally adjustable in the box-frame 13. The lateral adjustment of bearing 12, is effected by means of screw-bolts 14, which connect it with 13. The collar 15,- is secured to shaft 10, to prevent the longitudinal movement thereof. The opposing, circular,v crushing plates 16, and 17, are removably secured respectively to the interior surface of cap '2, and the bowl-shaped end'D of shaft 10. The bolts. 18 and. the central screw 19 are employed to hold said crushing plates in position but any other means of attachment may be used as may be-/best suited to the form of-said plates, either of which may be made in a single piece, as shown, or divided into parts constituting dies. The circular crushing plates 16, and 17, present opposing dished or concave surfaces inclosing between them the crushing cavity 20,

into which thecentral feed opening 21 .nally adjustable in supports 24, and 25,

thereby allowing the hood 22, to be shifted to suit the 'different adjustments of cap 2. Set-screws 27, are employed to lock shafts 23, in any determined position. The crossbar 2S, secured to the hood 22, supports the feed-spout 29.

It is to be noted that thel crushing plaie 17, secured to the enlarged end of shaft 10 is so mounted within the outer rotative shell j which carries plate 16, that the two crushing plates tend to rotate in unison, or concordantly, when power is applied to the beltwheel 9; and that this tendency of the two crushing plates to rotate together is due to the frictional contact of the ball and socket surfaces in the bearing 11, and is further due, when the machine is in operation, to the connections formed between the two plates by stone or other material wedged between them. It is' further obvious that when the axes of the two crushing plates are disposed at a' given angle to each other, the planes in which said plates rotate are respectively disposed at a like and equal angle. By this respectively oblique disposition of said plates they are caused to approach nearer to each other at 30 than at 31; and, likewise, during their rotation, two opposing halves of said plates are constantly moving in a zone of mutual approach, while two opposing halves are moving in a zone of respective recession. This method of maintaining, during operation, areciprocating or crushing movement of said plates, whereby material carried with said plates in their rot-ation is forced into a diminishing cavity, and so crushed, is the conception of primary importance in my invention.

When in -the operation of my machine, power is applied to rotate the crushing members as described, stone, ore,'or other material may b ev fed into the'spout 29, whence it falls within the crushing cavity until caught between the approaching rotating crushing plates and socrushed. At the same time said material' is borne forward by said members in their rotation, whence it derives a centrifugal force which operates to carry it outwardly between said plates during their opening or divergent movement. That part of the material which has been suiiciently reduced in size to escape through the peripheral opening between said plates, flies outwardly and is caught bythe to the speed of my machine. This aifords an important advantage over other machines fed by the limited force of gravity which is often insufficient to force through wet or sticky material and'sojprevent clogging. Especially is clogging-likely to occur in other machines when fine crushing is attempted both because no provision is made for spreading the material over a crushing surfacewhich presents an increasing area as reduction progresses, and because no provision is made for shortening the crushing stroke to suit the final reduction of small particles near the eXit of the crushing cavity. ln inymachine the crushing plates may be brought close together for fine crushing by turning the cap 2, on its threaded support at B, when said cap 2, is locked in position by means described.

The crushing stroke, or reciprocating movement of the crushing members, may be shortened by turning the screw-bolts 14, to bring shaft 10, more nearly parallel to shaft 1. The angle between the respective planes of the rotative crushing members is thus reduced. These provisions for adjusting the relative position of the crushing plates, and for regulating their crushing movement to suit such adjustment in combination with the provision made for the stone to vspread from the center 'to the circumference of a circular crushing area while in the process of reduction, especially adapt my machine for performing the work of fine crushing; while by reversing the adjustments descril'wd a coarse product may be readily obtained. Ry the arrangement of the two shafts with the ball and socket bearing an oil passage between them is provided for.

It will be understood that my inventiony relates for the most part to a Crusher in which the shafts are mounted on a supporting frame in substantially a horizontal position. When in such a position the means for preventing the relative longitudinal movement of the vtwo shafts is operative and of great importance.v The particular means .which I have shown are to be taken in a 25 I conditions which make-the feed by gravity carry the material outwardly andthe whole which mustbe so constructed as to present a central cavity the two faces Of which are removed more widely than the faces at the discharge portion, it tends of course to wear the crushing surface. Hence thenecessity f of fastening the crishing disk surfaces so that their attaching portions are not subject to such wear. This may be done as illustrated by attaching one wearing surface at the center or Opposite the feed opening and by attaching the other from the back so that the attaching devices lie entirely away from the effective crushing surfaces themselves. Some of the features of my invention are Of course applicable to amachine in a vertical position. When the shafts are in a vhorizontal position the end thrust due to the weight of the inner shaft is avoided the feed is directed toward the center under operation of spouting the material into the machine -and taking it from `it is greatly facilitated.

Having thus described my invention what I claim as new and desire to secure by Letters Patentl is:
