SPECIFICATION forming part of Letters Patent No. 529,692, dated November 27, 1894.

y Application filed January 22, 1892. Serial No. 418,908. (No model.)

State of New York, have'invented a certain.y

new and useful Improvement in Valves, vof which the following is a specification. y

My invention relatesA to improvements in valves and particularly the disks and spindles thereof, and the object of the improvement is to so form the disk and spindle that` the disk can be readily put on, secured, and removed from the spindle, and also that the disk when on the spindle may have a universal rocking motion so that it will compensate for irregularities in the valveseat. n

My invention consists, therefore, in the first place, in a Luniversal compensating valvedisk, and in the second place in the details of the construction, as hereinafter explained.

Referring'now to the drawings which accompany the specification to aid the description, Figuregl is a part section, part elevation of a valve with'my spindle and disk. The position of the spindle-flange in the disk fis represented by rectangular dotted lines.

Fig. 2 is a perspective view of the disk, Without the spindle. Fig. 3 is a perspective'vieyv of the key or feather, which locks thespindle in the disk. Fig.y 4 is an elevation of the Fig. 5 is a section of the disk on the line y--y of Fig. 2. Fig. 6 is a section ofv the disk on the sameline as Fig. 5, but also showing a section of the key in place in the,disk. Fig. 7 is a section of the disk on the line -x of Fig. 2 but showing the spindle, rocking-washerand key. Fig. 8 is an elevation of the disk as seen from behind.

Fig. l shows my spindle and disk applied to a globe valve, but they can be used in a variety of valves. A is the valve body havl ing the inlet port, o, and outlet port, af. b. b.

is the seat which may be of any suitable kind and construction as is common in valves, and this seat will preferably be placed eccentrically as respects the valve spindle C, for thereby the valve disk will touch the seat b,

b, on a different circle each time it is lowered,

because said disk turns freely upon the spindle as will be hereinafter explained, and therefore moves a little each time it is raised 'and 6.

from the seat.

passes the spindle,'C. Said spindle C has on its lower `end the circular flange, c, preferably formed integral with the spindle, C, and

serving to interlock the said spindle with the d`is'k,D, in the mannerhereinafter explained. Said disk, D, is constructed inthe following manner, namely: It has a ycircular flat bearing-plate, d, of somewhat greater diameter than :thediameter ofthe seatfb. b. and the under face, e, of said plate d is made plane and true, and also hard and indexical. -I therefore prefer to use'a quite hardmetal for the plate d. On the side of the said plate, d, opposite to the bearing face, e, is lformed a boss, f. Said boss f and plate, d, are readily cast integral, and said boss, j", hasa'mortise or chanreadily admit the flange, c, of the spindle, C,

and through the boss, as shown in Figs. 2, 5, Instead of casting the plate d and boss fintegral, said parts cl and f may be formed separately, and then the boss f,'may be readily'mortised, chambered and slotted as hereinafter described, and united to the plate d by rivets or bolts, but'the two parts-can be B is the bonnet with stuffing box, through which in the ordinary manner neig. g.which is of a width and height to cast integral, andthe mortise, chamber and' l slot be afterwardiea'sily formed ,in a manner well known to thoseskilled in the art. Immediately above the mortise'g. g. and opening tise g. g.and high enough to permit the flange, y c, to pass clear up into the chamber, but said chamber, h, is evidently shorter in the direction of 'the length'of m'ortise g. g. than is said mortise g. g..' so that near the front end of the said mort-isc g. g. are formed shoulders '1o. separating the front part of the mortise from the chamber; and if said mortise g. g. extends through and through the boss'f, there will be similar shoulders l. l. separating the rear part of said mortise from the chamber, h. over the middle part of the chamber, h, a long slot, fm, is cut through the lmetal of the boss, f, up to the top thereof. Said slot, m, is narrower than the chamber, h, and of a width to easily admit the spindle, C, but prevent the flange, c, from passing up through,

IOO

and saidslot, m, extends from near the rear face of the boss, f, forward and clear through the front face of the same, and at its front part said slot, m, is cut down through to the mortise g. g. Now it is evident from the foregoing description that the flange, c, can be slipped under the shoulders 7c. 7a. and slid back until said flange comes under the chamber, h, the spindle C, at the same time sliding back through the slot, m. Then the flange, c, can be lifted up into the chamber, h, leaving a clear channel beneath for the passage of the4 key, N. Said keyN is a lat strip of metal of thickness and width such that it can pass easily through the mortise g. g. under the flange c, and of a length equal to the diameter of the plate, d. The front end of the key N, is fashioned into a broader head, fn, with shoulders o. o. to prevent the key N, from passing clear through the mortise g. g. and near the rear end of said key is a threaded hole, p, to receive a threaded stop pin, q, which will bear against the back face of the boss, f, and prevent withdrawing the key. See Fig. 6. At about the middle length ot' the key, N, and so as to be directly under-the flange, c, there is fashioned in the said key, N, a depression fr, which in shape is a seg ment of a hollow sphere. Said depression o, is intended to receive the rocking washer, s, which is formed as a solid spherical segment coinciding with the surface of the depression 9*, and with dat upper face, and of a size to tit the depression r, in the key, N. Said washer s, is of such thickness that when it is in the depression in the key, N, the upper surface of the washer will be Hush with the upper surface of the key. By means of a flat key, N, without the depression r, and wash er s, I can lock the spindle C, in the disk D, and by reason of the loose lit of the spindle C, and flange, c, in theboss,f, the disk D will have a universal rocking motion, but I prefer to use the .rocking washer, s, in the manner described. Now the flange, c, being in the boss, f, as hereinbefore described, the key, N, with the washer s, is slid through the mortise, g. g. from front to rear, until stopped by the shoulders, o. o. Then said Washer, s, is directly under the ilange, c. Now the stop screw q, is threaded into the hole, p, in the key, N, so that the said key cannot be withdrawn, and the spindle and disk will be inseparably connected together for the spindle can only be taken out of the disk by lowering the ange, c, down into the mortise, g. g. and below the shoulders, k. k, but the key, N, does not permit the flange c, to be so lowered; also by reason of the easy t of the spindle, C, and flange, c, in the boss,

f, the disk, D, can rock universally on the spindle, C, and the washer s, will turn inthe depression, fr, as the disk rocks, so as to always give a good true bearing for the flange, c. Thus there is formed a universal joint, like a ball and socket joint, so that the disk, D, can compensate for irregularities in the form of the seat, b. b. Evidently in place ot' the boss, f, on the disk, D, said disk may be tnade somewhat thicker, and the boss be dispensed with. Then the said mortise, g. g. cham ber, h, and slot, m, will be formed in the disk; also it is evident that I can cause the screw, q, to entera threaded hole, in the plate, (l, so as to fix the key N, and then I can dispense with the head, a, and also when I thus engage the stop screw into the plate, d, I can out the slot, m, through to the rear face of the boss,f, all these changes being obvious and not varying the essential nature of the improvement.

Now, having described my improvement, I claim as my invention- 1. A valve disk having a mortise to admit the end of the spindle, an upper chamL er opening into said mortise and of less diameter in one direction than said mortise, and a slot from said chamber up through the substance ot' said disk, substantially as described.

2. The oombinationot a flanged spindle, a disk, a mortise in said disk adapted to admit said flange, an upper chamber communicating with said mortise but of less-Ar'dimensions in one direction and adapted to receive and retain said flange, and a key adapted to tit said mortise below said flange, substantially as described.

3. The combination with a disk and a hanged spindle adapted to a movable fit therein, of a key adapted to lit in the disk below the spindle and provided with a depression and a rocking washer adapted to fit in said depression beneath said spindle, substantially as described.

4. The combination with a flanged valve spindle, of a disk provided with a mortise g, chamber 7L communicating therewith, shoulders 7.: at one side of said chamber, slot m leading up from said chamber, recessed key N and rocking washer S, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 9th day of October,

CHARLES S. BAVIER.
