SPECIFICATION forming part of Letters Patent No. 277,763, dated May 15, ieee.

Application filed September 20, 1881.

To all whom it may concern:

Be it known that I, ROBERT MOGULLY, a citizen of the United States, residing at the city and county of Philadelphia, in the State ot' Pennsylvania, have invented certain new and useful Improvements in Ore Crushers and Pulverizers, ot'which the following is a specification, reference being had to the accompanying drawings, wherein- Figure lis a transverse vertical section of a pulverizer and crusher embodying my improvements.

Fig. 14c is an enlarged broken elevation of the same, partly in section. Figs. 15 andzlf are diagrams illustrating the preferable mode of setting the crushing and pulverizingjaws to obtain the best working results.

lVIy invention has for its object to provide an ore Crusher or pulverizer of extreme durability and great effectiveness, and so constructed that it will crush and pulverize an increased quantity of ore in a given time with less expenditure of power than can be accomplished with such class of machines as here tofore constructed.

My invention accordingly consists of the novel construction, combination, and arrangement of parts hereinafter described and claimed.

Referring to the accompanying drawings,

(No modeh) A A represent the housings or frames of my improved crusher and pulverizer, having' feet a n, through which pass screws or bolts a a, by means of which said housings or frames are rigidly secured to suitable foundations or otherwise, as desired. Said frames are connected together by transverse bolts a2 a2, which pass through tubes or nuts a` a inside of or between the lugs on the frames for the purpose of adjustment of the said frames. The latter have inclining sides a3 a3, as shown. They are also formed with bearings aA1 n.4 for the cam or eccentric shaft B, and with dovetail slots a5 a5, into which pass and have movement therein the frames C C. The latter form bearings for rods or shafts l), upon which are mounted the friction-rollers b li.

D Drepresent the crushing or workingjaws, secured by screws or keys d d in supports or holders E E. longitudinal slots e e, through which pass the friction-rollers b b', so that said supports will rest and partially move on said rollers. e e' are slots, elongated vertically, formed in one ot' the ends of said supports, and through which pass the cams or eccentrics B B', formed on shaft B, whereby when the latter is rotated the jaws D D are reciprocated longitudinally. Thejaws D D' are formed with Haring corrugated faces d d and straight, smooth, and partially-corrugated'faces al d', or the latter faces may be smooth and dat throughout their entire surface. The faces d d heilig' the crushing-faces and d d the pulverizing-faces, the Haring of the faces d l provides for a hopper, F, as shown, and, if desired, an extended hopper may be attached thereto.

Between theinclined sides alia-of the frames an d jaw holders orsupportsFl Eare placed antifriction rollers (I G." The rollers (l are sustained in a frame and roll, during the movement rof thej aws, against the adjacent surfaces of th e incline ctand ofjaw-holder E. The rollers G. rest against the surface of jaw-holder E and upon a series ot' double-inclining plates, H, secured to the frame A', as shown. The object whereof is as follows: As thejaw D' is reciplocated longitudinally the rollers Gr' move up and down the incline H, and thereby cause said jaw to be reciprocated transversely or to and from the jaw D. This transverse move- The latter are formed with' ment of jaw D allows said jaws to separate slightly, so that the ore will gradually drop or structed or provided with mechanism that the tendency of the same will be to keep said jaw away from or out of contact with jaw D, or hold said jaw D in close contact with its rollers Gr. For this purpose a spring, h, is secured to the housing A in any suitable manner.

I is a bracket secured to jaw-holder E', and

is formed with a bifurcated end, z', embracing spring h, and is provided with a roller, d', so arranged as to bear against said spring h, as shown in Figs. l and 2. The result whereof is that the elastic force of spring h is exerted against roller t'to cause jaw D to hug its rollers G and keep it out of contact with jaw D. Such contact ofthejaws will be effected only under the infiuence of the rollers moving up the inclines H. l

To take up th'e wear of the jaws I provide the following means: The frames C C are formedy with lugs c, having threaded openings c for the reception of ad j Listing-screws c2, suitably secured to transverse bars c3, bolted at cu1 to the housings. If desired, said screws may be provided with handles or winches c5. On turning the latter the screws c2 operate in lugs c to raise or lower the frames G C and with them the jaw-holders E E. If lowered, the inclining sides ofthe housings cause the jaws to come together, and'thus the wear of the same is compensated for. y

In Figs. 4., 5, 6, and 7 I have shown modifications of mechanism for effecting the transverse reciprocation of the jaw or jaws, wherein therinclines II are dispensed with; and the peripheries of the friction-rollers Gr' are partially formed with sides or arcs of larger circles, as shown at g g, which meet and form an apex,g, as shown in Figs. 4 and 5. In Fig. 4 such rollers are represented as being supported in a frame, and each roller moving independently. In Fig. 5 said rollers are each provided with a rigid arm, g2, which connects with a bar, G2, common to all said arms. Such connection of the rollers causes all of them to move simultaneously in whatever direction they are designed to travel. `In Fig. 6 the rollers have part of their peripheries formed with a surface of larger diameter, as shown at g3, and the bar G3 is connected to an eccentric, g4, on driving-shaft B, so that said rollers will be positively actuated during each reciprocatio-n ot the jaws.

yIn Figs. 8 and 9 I have shown toggle-levers K K, which may be substituted for the antifriction rollers just described, to effect said transverse reciprocation of thejaws. In Fig. 9 the levers K are shown provided with antifriction-roller bearin gs 7c It'.

The above-described forms of roller` mechanism and their modifications all'accomplish the same result-viz., the lateral movement of the jaws. Such movement may be increased or diminished, so as to obtain a quick or slow feed, as desired. For instance, the length of the inclines H may be such that the rollers will pass up and down the same twice during each full lon gitudiual reciproeation of the jaws. Hence the latter will laterally recede or open from each other and approach or close together twice during each of such longitudinal reciproeatlons. The result whereof is that the ore pulverized in the mill falls out thereof during each opening of the jaws, and when the jaws open laterally twice during each longitudinal movement ofthe same a quickfeed is obtained. Such number of openings and closings of the jaws is produced when the moditlcations shown in Figs. 7to 9 are employed, with like `results-viz., a quick feed; but it' the inclines H be made of such length that the roller will, during each full longitudinal movement of thejaws, travel only from the base to the apex, and then back again, then only one opening and closing ofthe jaws takes place, and in this case a slower feed is provided for. The simultaneous reciprocation ot' the jaws in different directions results in an angular pressure falling upon the ore to be crushed. Consequently such ore is more readily crushed and pulverized, and with less wear and tear of the working-faces ot' the jaws.

In Fig. l() I have shown a slight modification of construction of my invention, wherein the eccentric-shaft B is supported in bearings vfcation, wherein one of the housings A is so formed that it subserves the double purpose ot a housing for the mill and a jaw-holder, the jaw D being secured directly thereto, as shown, the interposed rollers Gr Gr being dispensed with. Said housing is in other respects coiistructed substantially as above described, the jaw D only reciprocating. In such construction only one eccentric on shaft B is used and only one set of anti-friction rollers G or toggles K is employed. Such construction I deem the preferable one where i tance beyond said vertical sides of the j aw-holdalso been moved transversely to close together.

ers. The middle parts, b5, of said shafts or rods do not rotate, and on them are placed, in any suitable manner, loose collars b, between which and surroundingeach rod or shaft is a spiral spring, L. Between the collars b6 and the jaw-holders are placed friction-rollers l, sustained in frames l. .y Said frames and rollers are held in position by means of lugs m, cast on said jaw-holders, and upon which said frames Z rest and move. The rollers Z are held in close contact with the jaw-holders by the elastic force of springs L, thereby tending to keep said jaws apart. When said jaws are reciprocated the movement of the rollers Z lessens the friction of such reciprocation. In all other respects the construction is substantially as heretofore described. y

. In setting thejaws for working I deem it a preferable plan to so arrangefthem that when their straight or vertical surfaces are pulverizing the ore they will be taking their feed ou their upper flaring surfaces, and when crushing between theirflaring parts the ore previously pulverized will then be eifectingits exit from between the straight surfaces of thejaws. Such arrangementis shown inFigs. 15 and 16. In the former the jaws are represented as having completed one-half oftheir longitudinal reciprocation, the rollers G being at the apex of the inclines H. Consequently said jaws have In such position theircorrugationsregister with each other, as shown, and they then take their feed. During such movement there has been only a slight crushing action performed by the upper flaring surfaces of the jaws, but their straightor lower surfaces have more orless completely pulverized any ore that may have been in positionbetween them. When thejaws haveV completed their return longitudinal reciprocation the rollers G are then at the bases of the inclines H. Consequently thejaws have also moved transversely to open from each other, and in such position their corrugations do not coincide with each other, as shown in Fig. 16. During such movement their flaring surfaces are then crushing the ore placed or fed between them, while ore previously pulverized by their straight lower surfaces finds its exit therefrom, and the more or less finely divided ore above then finds its way down to the said straight portions of thejaws, to be pulverized during the succeeding movements ot' the jaws, as above described. y

Such arrangement and operation of thejaws as I have stated I consider the most available to effect the best workingresults; but they may be varied as desired. signed tol use the -mill for crushing purposes only, the jaws are set the desired distance apart by manipulating the cranks c5.

I have stated that the foregoing-described machine may be used for crushing purposes only. So, too,`it` desired, it may be employed only for pulverizing, in which case the various In case it is departs of the machine will be made lighter in construction.

` It will be noticed that the slots in the frames E E tit the rollers b', but the shafts upon which the rollers are placed have their bearings inthe frames C O', as shown in Fig. 12. Hence when adjustment is made to take up the wear of the jaws the screws c a of frame A are loosened, thereby permitting the frames C C' to descend and push frame A farther apart from frame A. The more the frame A so moves the greater will be the descent of frames C C. As the latter so move the jaws automatically come together by reason of their resting upon the inclined rollers G G.

In an organized machine for crushing and pulverizing ore, a jaw, a supporting-frame therefor, and a movable jaw, in combination with a driven shaft and mechanism interposed between said shaft and jaw and between the latter and its supporting-frame, substantially as shown and described, whereby said jaw is positively actuated so as to have a simultaneous longitudinal and transverse movement with respect to the length ot' the machine, as
