STONE BREAKING AND CRUSHING MACHINE.
SPECIFICATION forming part of Letters Patent Ne. 251,038, aerea December 2o, 1881.
Application tiled August 1G, 1881. (No model.)
To all whom tt may concern:
Beit known that I, RYERsoN D. Gn'rnsa citizen of the United States, residing at Oliicago, in the county of Cook and State of Illinois, have invented anew and useful Improvenient inStone Breaking and Crushing Machines, of which the flllowing is a specification.
My invention relates especially to the stone breaking and crushing machine patented by I. NV. Gates June 28, 1881, No. 243,545; but it may be used in connection with all other similar machines having a shaft with a crushinge particles of stone, dust, ber provided with head above the gearing, and an oil step bearing-box below said crushing-head; and the object ofmy invention is to trap and confine small or dirt within a chama sponge, cotton, or other analogous soft arresting material, whereby the passage of such dust or dirt down upon the gearing and into the oil vstep beating-box is effectually prevented, and thus` undue wear from friction upon the shalt andthe gearing and bearing is avoided.
In the accompanying drawings, Figure l -shows a portion of a stone-breaking machine similar to the aforesaid I?. W. Gatess patented machine, and with my improvement applied thereto. The view is a verticallongitudinal section through the center of the machine. Fig. 2 shows a detail horizontal section in the line :r x of Fig. l, and Fig. 3 is a detail vertical section of a modied form of construction of my machine. Y
A represents the fraine of a stone-breaker; B, the concave or hopper; C, a gyrating shaft; E, the Crusher-head; E', the diaphragm or chute of the frame, this latter being, as usual, formed with a tubular ange, e, on its upper side, as shown.
F is the loose dust-guard collar or ring, f1tted loosely around the shaft C, and surmounting the tubular flange c in a manner to move back and forth on said flange, while the shaft gyrates and revolves within the bore of the collar or ring.
G is the oil step bearing-box. H is the adjustable screw thereof 5 I, an eccentric bearing for the lower end of the shaft C; J, a bevelgear Wheel attached fast to the eccentric bearing I; and K. is a bevelgear on the drivingshaft of theinachine.
L is a circular collar, ot tapering form, fitted loosely around the shalt C and resting loosely upon the bevel-wheel J. This collar is provided with a passage, s, over which a cover may be placed, and through the passage oil is snpplied from an oil-can to the oil step-box. The collar L may be termed a hoo-l, as it also serves as a dust-guard.
M and N are guard-flanges, for preventing the waste of oil; and mv are channels or passages for the circulation of oil through the step bearing-box G.
O is the ball on the upper end of the shaft C, and Pis the adjustable bearing for said ball. This bearing, as usual, may be made of chilled metal, forming segments ot' a cylinder externally and of a hollow sphere internally.
The machine thus far described and shown my invention.
'dust-guard collar or ring F to a very great extent prevents the passage downward of tine particles of broken stone and dust; but owing to the bore of said collar or ring requiring to be made a full one thirty-second part ot' an inch larger in diameter than that part of the shaft which it encircles, in order to have it gyrate with the shaft without binding, the dust will sift down through the tubular flange e upon the gearing, and into the oil step bearingboX, and form, with the oil, a gritty mass, which soon Wears out the gearing and bearing. To obviate this difficulty l provide a chamber, Q, of tubular form, on the under side ot' the diaphragm or chute E', as shown in the drawings. This chamber has an annular passage, q, in its bottom, and it is fully open at its top, and the diameter of this chamber is about the same as that of the one formed by the tubular flange e. The annular passa-ge q is of a diameter greater than the lower end of the shaft C, in order that said shaft, which passes through this passage, may have freedom to gyrate.
Upon the bottom of the chamber Q an annular loose ring or collar, R, is placed, and through this ring or collar the lower' and smaller end l of the shaft C passes, as shown. The ring or is well known, and of itself forms no part of With-the machine as above described the.
IOO
collar R is to serve a similar purpose as the ring or collar F, and its bore requires to be of larger diameter than that part of the shaft which it encircles, for reasons above stated with respect to the collar or ring F.
S is an opening, with a suitable cover or plug for closing it, in one side of the chamber Q. The chamber Q is provided with bolting-iianges t b, and by means of these iianges and bolts c it is firmly fastened to the under side ot" the diaphragm or chute E', and thus applied itl forms, with the tubular liange e, a cylindrical chamber or trap, d, between the loose collars or rings F and It.
Through the opening Ssponge, cottoinwaste, or other soft trapping material is placed in the chamber d, and this material g serves as a means for arresting the dust which may filter down upon it between the shaft C and the collar or ring F, while the collar or ring R serves for preventing the passage downward of any loose dirt or stone-d ust which may possibly sit't down through the soft porous sponge, cottonwaste, cotton cloth, or other material which may be in use. terial becomes dirty it can be removed through the opening S, and new or clean material supplied in its place.
In Fig. 3 ot' the drawings I have shown a plan whereby the chamber Q can be cast upon the diaphragm or chute il', and also have shown that the collar or ring R may be dispensed with. In this construction. as well asin theplan shown by Fig. l, should the collar or ring R not be used the sponge or other trapping material, g, is sustained upon the bottom of the chamber. I however prefer to use both collars or rings, inasmuch as the sponge might have atendency to work down when the collar or ring It is not Vhen the sponge or other niaused. I would also state that with myinvention the use oi' the hood L may be dispensed with.
1t is found to be a very important matter to provide a means for keeping dust and dirt out of the journal-bearing and gearing below the Crusher-head. In factthe successful operation of stone breaking and crushing machines depends in a very great degree upon the same, and I believe my invention accomplishes that object.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. The combination of the chamber Q, for containingsuitable material for arresting stone and ore dust, with the diaphragm' E ofthe frame, and with shaft C, stone-Crusher above the chamber, and a step-bearing below the chamber, substantially as and for the purpose described.
2. The chamber Q, provided with an opening in its side, and an annular opening, q, in its bottom,in combination with the diaphragm E', having tubular extension e, frame A, shaft C, loose colar or ring F, crusher above the chamber, and oilstep-box below it, substantially as yand for the purpose described.
3. The combination ot' the collar or ring R, trapping-chamber Q, collar or ring F, diaphragm or chute E', having tubular extension e, shaft U, with its erusher-head above the chamber, and the lower journal-bearing and gearing, substantially as and for the purpose described.
