CRUSHING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 348,757, dated September 7,1886.

Serial No.173,535. (No model.)

To all whom it may concern.-

Be it known that I, Ronnn'r MoGULLY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Crushing-lilachines, ofwhich the followingis a specification, reference being had therein to the accompanying drawings, wherein Figure 1 is a vertical central section of a crushing-machine with eccentrieally-gyrating shaft, showing my improvements. Fig. 2 is a plan of part of the top section or plate of the machine, showing bearing or boxes for the ball-fulcrum of the gyrating shaft and a crossseetion of the bolts for sustaining and vertically adjusting said boxes. Fig. 3 is a plan of part of the gear-wheel for imparting to the crushenhead shaft its eccentrieallygyrating motion, showing the fan-blades on its upper side for preventing entrance of dust to the bearings of said wheel and the eccentric formed thereon. Fig. 4 is a vertical section on a line at right angles to the line of the section shown in Fig. 1, showing more particularly the construction of the chutes; and Fig. 5 is a section through line 1 1, Fig. 1.

My inventionhas relation to stone or other crushing machines, wherein is employed an eccentricallygyrating crusher-head; and it has for its objects to so construct the parts of the machine that it is run or operated with less power than formerly required; that the adjustment of the ernshenhead and shaft for varying the fineness of the crushing and for taking up the wear of the crushing-faces is made from the top of the machine; that the eccen' tric driving-gear for the lower end of the crushenhead shaft is oiled from the top of the machine; that dust or debris is effectual] y excluded from the eccentric driving-gear hearing; that there is less frictional contact between the sleeve on the lower end of the gyrating shaft and the eccentric bore of the driving-wheel, and that the crushed material is conveyed quickly from the machine without tending to lodge upon or clog up any portion of the chuteways.

My invention accordingly consists of the combination, construction, and arrangement of parts, as hereinafter described and claimed, having reference particularly to an eccentricall y-gyratin g shaft and crusher-head freely suspended from or wholly supported by the top of the machine by means of bolts or other suit-able devices having adjusting -nuts or mechanism for raising or lowering the shaft and crusher-head, to adjust the latter for altering the fineness of the crushing and for taking up the wear of the crushingi'aces of the machine; to a tubular gyrating crusher head shaft having near its lower end lateral orifices or ducts leading to adjacent parts of the eccentric and its driving-gear and bearing of the latter, for effecting the oiling of said parts from the top of the machine, the hearing or box for the drivinggear having a valved outlet-duct for surplus oil, and also a draiirontlet; to a driving-gear having an eccentric bore, and upon its upper side a series of angular projections or blades surrounding said bore, for blowing or fanning away any dust or debris tending to gain access to the eccentric bore of the driving-gear; to a sleeve forthelower end of the gyrating shaft, which sleeve on its outside tapers in reverse directions from its horizontal middle to its ends; and, finally, to a two-way chute the top or meeting edges of which form a sharp ridge for preventing deposition of crushed material thereon, and avoid choking or clogging up the chuteways.

In the drawings, A represents the frame or housing of the machine, of preferably a circnlar or cylindrical configuration, and is composed of top plate or section, B, having feedopenings I), of crushingchamber 0, having crushing-faces c, of chute or exit-chamber D, and bottom plate, E.

F represents the gyrat-in g shaft; G, the crusher-head secured thereto; H, the driving-wheel having eccentric bore It, and in gear with a wheel, I, upon a suitable power'shaft, t.

The top plate or section, B, is provided with the usual or any suitable vertical central opening, 1), in which are located the boxes or bearings If for the ball-fulcrum f of shaft F. The boxes If are supported upon the heads is of bolts K, placed, preferably, in vertical slots or recesses b in the sides of opening I), as more plainly shown in Fig. 2. The bolts K pass upwardly through holesl in a plate or cross-bar, L, and are provided with nuts or other suitable devices, for impingement against plat-e L, to afford supports for the boxes ICO b and in turn for the shaft F and the crusherhead G; The shaft and crusher-head have no other supports, as the lower end of the shaft does not rest upon a set or tramming screw, as has heretofore been the case, but merely enters the eccentric bore of the driving-wheel H. (See Fig. 1.) As shaft F is freely suspended or wholly supported from the top of the machine by its ball-fulcrum f, the shaft and crusher-head are easily gyrated and an economy in the amount of power required for operating the machine is effected.

To raise or lower the shaft F and the crusher-head G, or to adjust the latter for varying the fineness of the crushing, or for taking up the wear of the crushing-faces of the machine, the nuts 7; are Simply turned or adjusted in the proper direction to slide the boxes If up and down in opening I), and the shaft and crusher-head following therewith, the desired adjustment of the crusher-head is made.

The bolts K and their adjusting mechanism and cross-bar L serve the double purpose of freely or wholly supporting the shaft and crusher-head and for altering the adjustment of the latter from the top of the machine.

The shaft F is preferably made hollow, or

- has a bore, j", which extends downwardly to lateral openings or dncts,f located below the top edge of the hub of the driving-gear H, as shown more plainly in Fig. 1.

The oil is poured into the top of the shaft through an opening, Z, in plate or crossbar L, which opening is closed by a screw or removable plug, Z'-. Plate L is preferably made large enough to completely cover or form a cap for opening Z), to exclude dust therefrom and keep the bearing-surfaces of the ball-fulcrum intact. The latter, as well as the driving-wheel, are oiled from the top of the machine, and, if preferred, at the same time. The driving-gear H has an elongated hub, 71', which, if desired, may be formed separately from the wheel, as shown. The hub h has its bearing in a box, 0, formed on plate E, and is held in position to support wheel H by means of an outside flange, h, resting upon the top edge, 0, of box 0. Surrounding the edge e is an annular flange, 0

forming a corresponding]y-sh'aped gutter, 0*,

adjacent to the hub-flange 71 and from this gutter a duct, 0 leads down through the walls of box a to its lower edge and through its cap or cover e and is furnished with a stopcock, 0. If desired, the cap may have removable or screw plug 6 for a purpose hereinafter to be described. The wheel H or its hub h has an eccentric bore, 71., for the recep tion of the lower end of shaft F, and by means of which the eccentricallygyrating motion is imparted to said shaft. The lower end of the latter is preferably provided with a suitable sleeve, M, held in place by a washer-plate, m, and screw on on the bottom of the shaft. Sleeve M may be made or configured in any desired way, or, in other words, it maybe a straight cylindrical sleeve, as heretofore employed. I prefer, however, to use a sleeve the outside of which is tapered transversely from its middle toward its ends, as shown in Fig. 1, the degree or inclination of the taper being the same or about that of the inclination given to the shaft F by the eccentric bore of the driving-gear. Only a portion of the top and lower tapered parts of the sleeve M are at any one time in contact with the eccentric bore h of hub J1 during the rotation of the latter or during the gyration of the shaft F, and the amount of frictional contact between sleeve M and eccentric bore h is thereby materially reduced without affecting the effectiveness of the machine.

The hearing or contacting faces of the shaft F, sleeve M, and wheel H are oiled from the tubular shaft F, and this is accomplished in substantially the following manner: \Vhen the lubricant is poured into shaft F, the cock 0 is opened. The oil escaping from lateral shaftducts f falls upon the sleeve M and works its way downwardly between sleeve M and eccen-. trio-bore h to fill the spaces above and below said sleeve, and thence works upwardly between hub 7t and box 0 until it reaches the top edge, 6, between which and the flange 7: it works out and overflows into gutter e, and finally passes out through duct 0. As soon as the oil escapes from cock e", or before this occurs, the filling operation is stopped. The cock 0 is closed when the oil ceases to drip therefrom, and a supply of oil is then contained in box a for thorough lubrication of the sleeve and eccentric and driving wheel bearings during the operation of the machine. Any accumulations of thickened or gummy oil in box 0 may from time to time be drained away by unscrewing or removing plug 6 To facilitate the upward passage of oil between box 0 and hub h the latter, preferably, is formed with outside vertical recesses, h", (see more plainly Fig. 5,) of which any suitable number may be used.

The top of the hub of wheel H is closed by a cap or collar, N, which is preferably loose upon shaft F and rests loosely upon the top of the hub. This cap is made large enough in diameter to extend over a series of angular or other shaped wings or projections 01, formed on the upper side of the wheel H surrounding the hub eye or opening 71. As the wheel H revolves its wings or projections a fan the air about the upper part of the hub of said wheel, and as the cap N rests upon said hub and extends over the wings a it tends to direct the air-currents produced bythe latter in an outwardly direction or away from the wheel-hub. These currents blowing or directed outwardly from the hub of wheel H fan or blow from it any dust tending to gain access to the bore of the hub. Oonsequentl y its inner workin g-surfaces are kept free from foreign dirt or grit.

The chute chamber or section D is provided with two ways or chutes, d (1, arranged on opposite sides of the machine. The upper or meeting edges, d, of the chutes form a trans verse sharp ridge, (2 of the same inclination as thatof the chutes, to prevent the lodgment of crushed material thereon and provide for quick exit of the material from the machine without tending to clog on the chuteways.

From the ridge d and chuteways projects upwardly an annular flange, p, which is surrounded by a like flange, 1), depending from a sleeve, P, which may be secured in the usual or any suitable manner, as shown, to shaft F, to receive the crushing-faces G of the crusherhead G. I, however, prefer to cast sleeve P on said shaft. These annular flanges pp tend to prevent dirt or dust passing into the chamber D beneath its chutes, as the crushed material falls upon the chutes outside of said flanges.

The crusher'faces G may be constructed as desired, and are preferably connected to sleeve 1 by molten lead or metal keys p in the usual manner.

' To firmly support the crusher-head G upon sleeve I, the latter is preferably formed near its bottom with a shoulder, 11, upon which the 1 crusher-head G rests.

The casting of the sleeve 1? upon the shaft F, in addition to the use of the molteirmeial connection for the crushing faces G and sleeve P. ad mitsof securinga crusher-head, the parts of which are firmly secured to the shaft and to each other without fitting orfinishing. The chamber (1 is formed near its bottom with a like shoulder, c, to support its crushingfaces c, and to prevent the latter moving or rising in said chamber they are formed near their upper ends with outside projecting flanges, 0 which fit into correspondingly-shaped adjacent recesses c in chamber 0."

If desired, two flanges may be formed on the faces 0 and two recesses made in chamber 0, as indicated by dotted lines as, Fig. 1, to more effectually maintain said crushing-faces in place.

By the employment of the flanges c and recess c the advantage of obtaining the full thickness of the crushingfaces at their top parts is obtained, and they are therefore not liable to break off. Said flanges and recess also prevent the upward crushing strains or pressure against the faces 0 falling upon the joint between chamber 0 and its top plate, B, and hence all tendency to loosening the bolts connecting said parts is avoided. The various sections of the frame of the machine are suitably flanged, bolted, as shown, or they may otherwise be secured together, as desired.

In the drawings I have shown two bolts, K, for the boxes Ir of shaft F, and these bolts 10- eated between the boxes and the sides of the opening Z) in top section, B; but I do not limit myself thereto, as other means shown and described in an application of even date here with, Serial No. 173,536, may be substituted for said bolts.
