CRUSHER.

Specification of Letters Patent.

Application filed October 10, 1912.

Patented Feb. 24, 1914. Serial No. 725,018.

To all whom it may concern Be it known that I, OLIVER J. MoUssET'rE,

I a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Crushers, of which the following is a specification.

This invention relates to crushers or pulverizers, and has for its object the provision of a comparatively simple and thoroughly eflicient machine which may be used for grinding ores or similar material and will be especially adapted for reclaiming brass or other metal from the refuse of refineries, foundries, smelters, and the like.

- The invention has for one object the provision of a crusher so constructed that the finely ground material may be fed from between the crushing members as it is pulverized and deposited in a suitable receptacle.

The invention also seeks to provide a crusher so constructed that the material being treated will be continuously acted upon by the crushing members and the collection of the unground material between the active crushing members in such quantity as to arrest the action of the machine will be prevented.

The invention also seeks to provide a crusher of the rotary drum type which may be easily operated, and also seeks to improve, generally, the construction and operation of crushing machines to the end that the efliciency and durability of the same may be increased.

The several stated objects of my invention, and other incidental objects which will ap pear as the description of the invention proneeds, are attained in an apparatus of the type illustrated in the accompanying drawings, and the 'lIlVGIltlOll res1des 1n certam novel features which will be hereinafter full disclosed. and particularly pointed out in the claims following the detailed description.

In the'drawings: Figure 1 is an elevation of a crusher embodying my present improvements; Figs. 21s a /plan view of the same; Fig.- 3 is a vertical longitudinalsection; Fig.

4 is a transverse vertical section; Fig. 5 is an enlarged sectional view through the outlet controlling rings and the screen showing the parts separated and in their proper relative positions; Fig. 6 is a detail perspective view of a portion of one of the outlet controlling rmgs.

In carrying out my invention, I employ a supporting frame or base 1 which is pref erablyconstructed of. a single integral casting) comprising corner posts, a transverse we 2 connecting the posts at the. ends of the frame, and a longitudinal brace or connectlng bar or Web 3 extending between the said webs. Upon the upper ends of the posts are provided journal boxes 4 whiohreceive. and support the parallel shafts 5 extending longitudinallyof the frame at the opposite sides thereof. Upon these shafts, adjacent the ends of the frame, are flanged rollers or wheels 6 through which motion is imparted to the drum. Between the rollers or wheels 6, at one end of the supporting frame and the adjacent side of the housing 7, sprocket wheels 8 'are fittedrigidly upon the said tion, and, as there are no unnecessary parts;

the cost of installation and maintenance is minimized. It will also be noted that the described arrangement brings the sprocket chain and the wheels upon which it is trained below the drum so that the employment of a casing or housing for the driving gearin is rendered unnecessary.

The ousing 7 fits around the central longitudinal brace 3 of the supporting frame and projects upwardly therefrom to extend around the drum 13. Rings 14 of leather or heavy cloth are secured to the sides of, the housing and fit closel to the drum to prevent escape of dust. hese rings may be secured in any desired manner, preferably by clamping rings and bolts, as shown in Fig. 3.

fixed head or closure 19, as shown. The terpast the same when-t e drum is in use Wlll receptacle A receptacle is placed below the brace 3 and is fitted closely to the lower end of the housing so that the leakage of the finely ground'matter between the housing and the cannot joccur. The drum issupported upon and driven by the rollers 6 and consists of the inner tapered or substantially conical sections 16 having the driving rings 17 formed at their outer smaller ends to bear directly upon the rollers 6 so that, when the said rollers rotate, the rotary motion will be imparted directl to the driving rings and the drum there y rotated about its own axis. As the shafts are connected by the s rocket chain and wheels above described,

both shafts will be positively rotated and, consequently, the rollers on both shafts will .beactuated and slipping of the drum upon some of the rollers, with the consequent frictional wearin away of the contacting surfaces, isavoi ed.

Secured rigidlyto the outer ends of the drum sections. 16 are terminal members 18 .whicha're of similar tapered or conical formation and one of which is provided with a minal member 18 at the opposite end of the drum has-rigidly secured thereto atubular tenal ma member 20 which is preferably in the form of a spout, as shown in Fig.3, so that mabe readily fed into the drum through t e said spout or feed "member, as

will -be readily understood. This feed or inlet member or spout is closed by a cover or lid 21 which is pivoted to the upper end i of a supporting armor standard 22 rising said log or cam and, consequently fromthe base the said lidor cover is formed a ra 'al proj'ection or cam 23 whieh abears against a spring presser plate secured upon the arm 22. The projection or cam 23 is so i sposed that when the cover 21 is swung npwardl against the end of the inlet member-120 the orce of the spring plate 24 will be directed downwardly agains't the the cover will beheld firmly against the mlet of the drum so as to close the same and prevent the escape of material therethrou h. If the lid or cover be swun d'ownwar y against .the pressure of the said plate 24, the plate will yield to the upward outward movement of the'lu and will thenbear uponthe underside 0 the said lug or cam so that the premature closing'of the lid-or cover will be prevented. .It will thus be seenthat I have provided an exceedingly. simple device by which the lid or cover may be held in either o'fits; positions s0:that premature closing bf the same will be rev'ented and leakage also be prevented andthe use of packin and expensive locking devices is rendere ame 1. .'Upon the ivot of the reason that, while the spring presser plate will hold the lid or cover in the position in which it may be set, the plate will yield readily to manual force exerted upon the lid to shift the same.

The inner ends of the main section 16 of the drum do not abut, but are spaced from each other to accommodate a pair of rings or disks 2;) which aid in the crushing of the material and also control the discharge of the crushed material. These rings or disks are provided on their opposed inner faces with spacing lugs 26 which, by being placed in contact, holdthe disks or lugs slightly separated and thereby provide an intermediate passage 27 through which the ground material may escape. The lugs, furthermore, constitute additional breaking members which will be brought against the particles passing into the space between the disks by'the rotation ofthe drum with such force as to further disintegrate the same. The inner faces of the disks are inclined or beveled so that the space 27 flares toward the outer edges of the disks and, consequently, the particles passing beyond the lugs 26 at the inner edges of the disks'may readily pass from between the same. At the outer edges of the disks are provided additional spacing lugs 27 and these lugs 27 not only aid in holding the disks. in their spaced relation, but,also reinforce the disks by providing enlargements through which the securing bolts 28 may be passed to secure the disks in position. In the outer faces of the disks or rings are formed a plurality of radial grooves 29, the outer ends of which are flared, as indicated at 30, and these grooves constitute outlets for the material, as" will be readily understood. A screen 31 is arranged concentrically around the drum, and this screen is preferably constructed of a sheet metal plate having small perforations or openings 32 terial. The screen is held in spaced relation to the drum and the outer peripheries of the disks or rings 25 by a series of brackets 33 having their inner ends fitted upon the bolts 28 and secured by the said bolts against the annular radial flanges 34 formed on the main sections of the drum, the outer ends of the said brackets 33 being extended axially with respect to the drum and fitted in the grooved collars 35 which also fit over the edges of the screen. Set-screws 36 are mounted in the outer sides of these/collars and engage the screen so as to pass through the edges of 'the same and bear upon the ends of the brackets whereby the screen and the brackets will be securely clamped within the collars and the screen thereby supported upon the drum. It will also be noted that the bolts 28 secure the brackets to the drum and the innermost sections of the drum, as well as the rings interposed between. the said sections, together. a

' The screen extends close to the upper por tion of the housing 7 which is imperforate and is preferably cylindrical in form, while the lower portion of the housing is shaped to provide converging walls serving as guards to deflect the material escaping through the screen into the receptacle 15 placed below. the housing. The housing is provided with a man-hole 37, and a portion of the screen, indicated at 38, is made to serve as a door by being cut out of the main portion of the cylindrical body of the screen and hinged thereto so that if it be necessary to clean 'or repair the' itcreen or the drum,

the drum and screen may be rotated so that the door 38 will be made to register with the man-hole 37 and, access then may be had to the interior of the drum, as will be readily understood.

Crushing rollers 39 are mounted loosely within the drum and these crushing rollers may be of the usual conical form. The rollers. rest loosely within the drum upon the bottom portion thereof and have a somewhat greater taper than the main sections of the drum so that the inner opposed ends of the rollers will flare upwardly with respect to each other. These larger ends of the rollers are preferably corrugated or otherwise roughened,as indicated at 40, so that'as the rollers rotate the material cau ht between the same will be thoroughly bro on up and reduced. The said inner ends of the rollers are constructed with central concave recesses 41 which receive the eyes 42 on the inner ends of eye-bolts 43 passing through the central bores of the rollers and of a diameter to substantially fill the said bore, but, at the same time, permit free rotation of the rollers. Nuts 44 mounted on the outer ends of the bolts serve to retain the bolts in position within the rollers, and a link- 45 is fitted through the eyes 42 of the bolts and extendsbetween the same so that the rollers will be effectually coupled and held in their proper relative positions with ofthe said spout so as to close the same, as previously stated. The power of the prime motor isthen transmitted to theshafts 5 by shiftir the driving belt onto the fast pulley, an' thesaid shafts-will then conse- -be rotated. The rotation of th? saidis afts being imparted directly to the Yes rollersfor supporting wheels 6, the drum will immediately be set in motion through the frictional engagement between the said rollers and the driving rings 17 on the drum. The material fed into the drum will tend to accumulate in the lowest point of the same and will, consequently, be caught between the two crushing rollers, between the rollers and the sides of the breaker rings or disks, and also between the bottom of the drum and the rollers so that the weight of the rollers will be exerted to.

will carry the same around so that they will be again deposited upon the body of ma terial in the drum, the result being that only small particles will be permitted to escape to the screen and any particles which are too large to pass through the screen will be subjected to a rolling disintegrating action through the rotation of the lugs 27 at the outer ed es of the disks and will also return to t e interior of the drum to he again treated. The finely ground material escaping between the rollers and the bottom of the drum will enter the radial grooves on the outer faces of the disks and will escape through the same readily and rapidly to the screen. It will also be noted that the screen is rigidly connected with the drum and consequently rotates with it so that the particles of matter too large to pass through the screen will be carried around and dumped upon the upper portions of the rings or disks 25 where they will enter the space between the disks and settle upon the lugs 26. tending to pass between the said lugs and consequently bein brought into position to be broken up by the lugs and the rollers.

My improved crushing machine is composed of very few parts and will be found highly eflicient in use and its many advantages are believed to be evident from the foregoing description without further detail mention of the same.
