STEAM AoRr-STArvl P.
SPECIFICATION forming part of Letters I latent No. 608,423, dated Angust 2, 1898.
. y 4 Application filed May 3, 1897.v semina. 634,874'. (No maar To @ZZ whom, traag/,concern- Be .it known that` I, DAVID lOoLE, a citizen of the United States,l'residi1'xg at Chicago', in
the county of Oo'okand State of Illinois, have invented certain 4new'faiid useful Improvements in Steam Ore-Stamps',`of which the fol-- lowing is a specification.
The object of my invention is to provide the valve mechanism with efficient cushion-stops arranged outside the valve-chest.
A further object is to provide mechanism for adjusting the lateral 'position of the stamps, so as toV equalize the wear caused by the crushing of ore between the die and the shoe vWhichis attachedftotlie stems; and the invention consists in the features, combinations,l and details of construction hereinafter described and claimed. l
In the accompanying drawings, Figurel is a front elevation ofy a steam ore-'stamp constructed in accordance. with my improvements, part of the mortar being broken away, so as to show the shoe attached to the same and other parts; Fig. 2,`a'side elevation of the same with a portion of the mortar broken away; Fig. 3, a cross-sectional viewv of the cylinders and valve-chest, taken on line 3 3 y of Fig. 2, looking in the direction of the arrow; Fig. 4, a longitudinal sectional view of one of the cylinders and valve-chest, taken on the irregular line 4 4 of Fig. 3; Fig. 5, a
side elevation of the valve-chest, shown partly' in section, taken on line 5 of Fig. 3, looking in the direction of the arrow; Fig. 6 is asection taken through line 6y 6 of Fig. 3; Fig. '7, a side elevationpof the valve-rod, partly in section; Fig. 8, a plan view-of the under side of the controlling slide-valve, with the piston for moving the same shown in dotted outline; Fig. 9, a plan view ofthe top of the slidevalve', with the lpiston for moving the same shown in dotted outline Figi'10, a plan view of the top of the valve-plate, looking` at it from line 10 10 of Fig. V3; Fig. 11, a plan view of the ybottom side of the valve-plate, looking at it from line 11 11 ofFig. 8; Fig. 12, a plan view of the top of the cylinders to which the valve-'plate is attached, vlooking at itmfrom line 1212 of Fig. 3; Fig. 13, a cross-sectional view taken on line 13 13 of Fig. 8, Fig. 14, a cross-sectional view'taken on line 14 14 of Fig. 1, and Fig. 15 a front elevation of the guide-blockand other parts shown particuylarly in Fig.Y 14.
In constructing a steamstamp in accordance with my improvements I make a frame portion of the desired size,shape, and strength, adapted to hold and sustain the movable and other parts in operative position, and which comprises a base portion A, which contains the mortar B, four pillars or posts a, on which the cylinders O are mounted at the upper end thereof. The cylinders are provided with movable stamp-pistons O O2,having stem portions c' c2 projecting downwardly therefrom and carrying the shoes C? and O4, between which and the dies C5 the material is crushed or pulverized during the reciprocations of the pistons. The lower part of the cylinders is provided with stuffing-boxes cs and the upper part with a head D, which forms avalveplate on which the controlling-valve operates. To permit the admission and exhaust of the steam from both of such cylinders, I provide the valve-plate with a number of inlet and exhaust openings or parts,which connect with inlet and vexhaust passages in the cylinder, the operation of which is controlled largely E, which is moved back and forth upon its seat by means of a valve-rod F. This valverod has stem portions f, projecting out of each lside of the valve-casing, and which are provided with cushion-stops or buffers f f2, that are arranged to contact with stops f3 fLl on some ixed portion of the cylinder or valvecasing. In the drawings I have preferred to show them as fixed to the heads of the valvecasing. I
. In order to set the valve, and vthereby' control the operation of the pistons and other parts, or to move the valve from one position to another, I provide what I Aterm a starting-lever G and removably pivot it atg to a iixed portion of the valve-casing. This lever is provided with a bifurcation g', that vstraddles a portion of one of the cushion-stops, so that the slide-valve may be moved by manual force from one eXtreme to the other or to any point intermediate the same. This lever is used merely for the purpose of starting the mechanism and is then removed.
TOO
nection, thereby causing the said valve-rod, pistons, and controlling-valve to travel to their opposite limit of motion. This operation is such as to connect the various ports necessary to alternate the action .of the stamppistons. In this mechanism there is no provision made for exhausting the pressure from either end of the valve-pistons except through the same port used for admitting the high pressure and by Way of the regularexhaust operated by the controlling-valve itself. The movement of the valve-piston and valve is accomplished by the difference of the high and low pressures on opposite ends of the valve-rod caused by the expansion and consequent lowering of the pressure in the cyliuder in which one of the stamp-pistons is descending. f
To regulate the amount of travel of the valve-rod and its attached parts and overcome the shock incident to such movement, as well as to provide means for taking up the wear,
the cushion-stops or buffers above described` are provided, and attached to the steam-chest are the stops above described, which are held in position by means of studs P P. These studs are adjusted at equal distances from the steam-chest to receive the stops, which are held in place by means of nutson the ends Y of said studs. The ends of the valve stem or rod are threaded, so that the cushion-stops may be adjusted thereon' and regulate the travel of the valve, as well as compensate for the wear on the buiers. l
In the use of mills of this kind it is found that some point or points of the face of; the shoe or die, or both, wears faster than other portions, making it desirable and necessary to shift the position of a given point on the faces of such parts and to hold it in such po-v sition until the uneven Wear is compensated for. In order to accomplish this result, I provide the piston-stem with keyways or slides, as indicated at 1, 2, 3, 4, 5, and 6 in Fig-14. These keyways are of such length as to allow for the reciprocations of the stamp and for the lowering of the cylinder to compensate for the wear upon the shoes and dies. A
frame R is provided which carries the guidebloeks 7 and 8 and is provided with two pair ofbosses 9 and l0 and 11 and 12, between which is removably held the keys 13 and 14, which enter the desired slots or keyways in the stamp-stems, such keys being held in the same adj ustably by means of the set- screws 15 and 16. When it is ascertained that uueven wear is taking place on the shoe or die, or both, the key of the stem carrying such shoe or die may be withdrawn and the stem, with its shoe and die, rotated to a point that will tend to overcome this condition, the key reinserted, and the parts secured in position. The holding of the stem while the parts are operated in this manner will tend to equalize the wear and is a decided advantage over the rotation of the parts in a step-by-step automatic manner.
I claim- 1. In a steam ore-stamp, the combination of a cylinder, provided with a reciprocating piston, a reciprocating controlling-valve for admitting and exhausting steam into and out of the cylinder to operate the piston, aud provided with a valve-stem projecting outof the valve-casing at each end, a cushion buffer-collar on each end of the valve-rod, and stop mechanism arranged on a rigid portion of the machine between the valve-casing and the cushion -collars, substantially as described.
2. In a steam ore-stamp, the combination of a cylinder provided with a reciprocating stamp-piston provided with a plurality of lon` gitudinal slots or grooves arranged in alinement and parallel with the motions of the piston, a key removably secured to a rigid or immovable portion of the machine and adapted to enter one slot at a time, the whole so arranged that the lateral position of the stampstem with its top parts may be changed by shifting the same and engaging the key with another groove, substantially as described.
