MACHINE FOR GRINDING VALVES ON THEIR SEATS.
SPECIFICATION forming part of Letters Patent No. 347,130, dated August 10, 1886.
Application filed October 6, 1885. Serial No. 179,098. (No model.)
To all whom it may concern.-
Be it known that we, ELIJAH U. SOOVILLE and OLINToN OWEN, of Manlius, in the county of Onondaga,- in the State of New York, have invented new and useful Improvements in Machines for Grinding Valves on their Seats, of which the following, taken in connection with the accompanying drawings, is afull,
clear, and exact description.
The purpose of this invention is to accurately and expeditiously grind a number of valves 011 their respective seats, and more particularly to grind the curved valve on the correspondingly-curved face at the discharge end of the faucet for which we have obtained Let ters Patent of the United States No. 301,759, dated July 8, 1884. w
The invention consists, essentially, of a series of holders for the valve-seats or faucets, reciprocating valve-carriers arranged over the valve-seat holders, and pivoted connections between the valves and valve-carriers, whereby said valves are allowed to conform their positions to the contour of the valve-seats.
The invention also consists in the combination,with the valve-seat holders, reciprocating head,and valve-carryingarms pivoted thereon,
of a guide arranged tocarry the valve-carrying arms back and forth across the valve-seat holders laterally'from the movement of the reciprocating head, said movement causing the valve to be ground uniformly over the entire valve-seat; and it also consists in the com bination,with the reciprocating head and the valve-carriers connected therewith, a slide connected with said head, and the pitman connected with the slide, of a crank-pin connected with the crank adjustably in relation to its distance from the axis of the crank, by which arrangement the stroke of the valvecarrier can be varied according to the length of the valve-seats to be operated on; and the invention furthermore consists in novel devices for securing the valve-seats or faucets in proper position on the frame, all as hereinafter more fully described, and specifically set forth in the claims.
In the annexed drawings, Figure I is a plan view of our invention,with portions broken away to better illustrate certain details of the machine. Fig. II is-a side elevation of the same. Fig. III is a transverse section online a; m, Fig. I. Fig. IV is a face view of the adjustable crank; and Fig. V'is a transverse section on line y 3 Fig. IV.
Similar letters of reference indicate corresponding parts.
F represents the main supportingframe of the machine,which frame cousists,mainly,of a stout table or platform mounted on cast-iron legs, which are bolted to the floor. Horizontally across the' front of the frame F are extended three bars, I I I, which are secured at their ends to plates I, supported on rigid arms R, firmly bolted onto the frame and projecting therefrom. One of the bars I is in front of the other two bars and sufficiently distant therefrom to receive between them a series of valve-seats, which in this case are represented in the form of faucets f, having at the discharge ends segmental faces, on which correspondingly-curved valves 1) are to be ground. Said faucets are held in a row and adjustable in position with their segmental faces upward by means of set screws H H, extending through the bars I I, and bearing on the front and back of the fancets, and arms H, connected to the bar I, and having their free ends bifurcated to receive the trunnions formed on the sides of the fancets. The faucets are thus hung on the arms H. The set-screws H pressing on the front of the faucets retain the latter on the arms H, and the other set-screws H, bearing on the back of the faucets below the front set-screws, serve to adjust the faucets so as to carry the valveseats thereof in their requisite position to be ground, as hereinafterdescribed. The set-screws H H and arms II thus constitute the holders for the valve-seats, and will hereinafter be referred to under said designation.
A represents a reciprocating head or bar extended across the top of the frame F,parallel with the row of valve-seat holders, and is moved toward and from the same by the instrumentalities hereinafter described.
On the reciprocating head A are pivoted a series of valve-carrying arms, B B, which are flexible vertically and have their free ends extended over the valve-seat holders, and are provided thereat with a pivoted connection for the valves, which connection consists of a ICO socket or indentation in the under side of each arm 13 and a stud-pin projecting from the back of the valve 1) into the aforesaid socket. This pivoted connection between the valve and its carrier 'B allows said valve to rock and conform its position to the contour of the valveseat.
Across the series of valve-carrying arms B B is extended a bar, 0, which receives a reciprocating motion at right angles to that of the head A, as hereinafter explained, and is guided in its movement by a longitudinallygrooved guide-bar, E, secured to the frame F underneath the bar 0, in the groove of which guide-bar is mounted a slide, c,connected with the bar 0 by bolts 0, as shown in Figs. II and U I of the drawings. To the under side of the bar G are pivoted a series of guide-blocks, 'u, in which slide arms Z) Z), firmly clamped on the valve-carrying arms l3 B. The free ends of the said arms l3 13 are thus carried laterally back and forth by the reciprocating bar 0, and the valves 'v are moved both longitudinally and laterally over the valve-seat. Said movement of the valves causes the same to be ground uniformly over the entire valve-seat, and produces a perfectly-tight joint between them. A spring-bar, l), secured to the top of the frame F, and bearing with its free end on top of the bar (1, applies the requisite pressure to the valve-carrying arms B B.
The head A and bar (J receive thci r respective reciprocating movements by the following instrumentalities: Parallel with the barf) is the driving-shaft (I, mounted on pillow-blocks or suitable bearings secured to the top of the frame Fback of the head A. S and S designate, respectively, the driving-pulley and the loose pulley connected with the aforesaid shaft in the usual and well-known manner. Near the center of the frame F is a crank, L, secured to the driving-shaft (Z, and under this crank is a slide, N, mounted on a guide, 71, firmly attached to the top of the frame F at right angles to the head A, with which one end of the slide N is connected. A rigid arm, 3'', rising from the slide N has on its upper end a wrist-pin, a, and the pitmau 0, connected with said wristpin and with the crank-pin L, connects the slide N with the crank, so that the rotation of the latter imparts reciprocating movement to the head A through the medium of the slide N N. I11 order to admit of regulating the length of the stroke of the head A according to the length of the valve-seat to be ground, we secure the crank-pin L on the crank arm or disk L, adjnstably in relation to its distance from the axis of the crank, and this we accomplish by means of a block, 8, sliding in a diametrieal groove, 0', in the face of the crank-disk L, said groove being T-shaped in cross-section, and the block 8 formed correspondingly to retain it in the groove, as shown in Figs. 1V and Y of the drawings. The wristpin ll is provided with a serew-threaded shank, i, which passes through a correspondingly screw-threaded eye in the block .9 and bears on the face of the groove 1', and thereby holds the said block in its required position. By turning the wrist-pin L so as to loosen the block 3, the latter can be moved toward or from the axis of the crank to carry the wrist-pin to its required position in relation to said axis,whcre it can be retained by tightening the wrist-pin. On the side of the frame F is secured a trunnion or gudgcon, on which is pivoted a camwheel, K, and a gear-wheel, T, which latter meshes in a pinion, U, attached to the end of the driving-shaft (7. On an arm, n, or other suitable support, is pivoted a lever, M, one end of which engages the cam-groove of the wheel K, and the opposite end projects between two set screws, i? 13, working in lugs l 1, attached to the top of the bar 0. The revolution of the driving-shaft (Z causes the eamwheel K to impart oscillating motion to the lever M, and this in turn imparts reciprocating motion to the bar (J. The set-screws i i constitute an adjustable connection between the lever M and bar 0, allowing said bar to be shifted longitudinally on the said connection, so as to cause the arms 13 B to carry the valves in their requisite positions over the valves to be ground.
It will be observed that the described machine can be extended almost indefinitely to contain a great number of valve-seat holders arranged in a row with a corresponding nnm' ber of 'alve-carriers 13 1; over them; and they may be arranged at opposite sides of the frame F, and motion can be transmitted to the second set ot'valve-carriers from the same d riving-shaft, crank, and cam-wheel by a second and similar set of reciprocating heads, A, reciprocating bar (1, and lever M, and an extension of the slide N, as representedin Fig. l of the drawings.
