VALVE-G EAR FOR SLIDE-VALVES.
SPECIFICATION forming part of Letters Patent No. 626,261, dated June 6, 1899.
Application filed December 24,1898. Serial No. 700,210. (No model.)
To aZZ whom it may concern.-
Be it known that I, SYDNEY WILLIAM WIL- KINSON, a subject of the Queen of Great Britain and Ireland, residing at Crookes Place, city of Sheffield, county of York, England, have invented an Improvement in Valve-Gear for Slide-Valves, of which the following is a specification.
The object of this invention is to simplify the valve-gear of slide-valves of steam-engines and especially the valve-motion of threecylinder engines for vehicles, launches, and the like.
The invention is illustrated in the annexed sheets of drawings.
Figure 1 is part of the steam-chest with the slide-valve and means for regulating and re versing; Fig. 2, a plan of same with portions removed to show the parts underneath; Fig. 3, an end view of steam-chest and valve with the end plate removed to show interior.
In the application of my invention to the slide-valves of a three-cylinder engine, for example, in which steam is admitted to the back of the pistons only, the front or lower end of the cylinder being open, the steamchest A is situated above the cylinders O, and
to which the piston-rods are connected in the usual manner.
The steam-ports D and the exhaust-ports E communicate with the upper end of the cylinders and are operated by the slide-valve V, which is chambered at J, its sides V being carried upward and connected at the top by a cross-bar K. It slides between the two guide-plates R.
lVithin the sides of the valve is fitted a slideblock L, which is carried by and encircles a cam M, upon which it is held by means of screws L passing through it and entering a grooved path P, made in the periphery of the cam, or into a ring fitted into such path.
The cam is preferably made in halves for convenience of construction, and centrally through the cam I make an oblique slot m to receive a correspondingly-shaped adjusting plate or key N, which is firmly sccu red upon a sliding spindle H by screws 72.
Through the steam-chest A is passed a tu bular revolving shaft F, supported in bearings G at each end,and longitudinally through the center hole of this shaft is passed the spindle H, which carries the inclined adjusting-keys N.
Through the valve-shaf t F and its collars F extending from F to F, a slot is cut to permit the lateral movement of the inclined key N, which can be traversed to the right or left, as desired, by moving the spindle H within the tubular shaft F.
The movement of the key N from the position shown in Fig. 1 toward the position indicated in dotted lines will raise or alter the position of the cam M and also the travel of the valve, thus enabling the cut-off to be adjusted to any desired amount, or by moving it past the center position the revolutions of the crank-shaft can be at once reversed.
The central part of the oblique slot through the cam is enlarged to an oblong rectangular form at Q to permit the passage of two short bar-shaped pieces, (marked F in Figs. 2 and 3,) which form part of the shaft F, between the collars F This part of the opening is made of sufficient length to permit the re quired adjusting movement of the cam.
The above-described arrangement of the valve, slide-block, cam, and inclined key is repeated for each cylinder; but the three sets of valves are all operated by one shaft F and spindle H, whichare made long enough for the purpose.
The end plateT of the stea1n-chest A is made with a chamber S to receive and in close the end of the spindle H when it is moved to the end of its travel. The opposite end plate (not shown) is made with a gland or stuffing-box, through which the end of the shaft F projects, and is rotated at the same speed as the crank-shaft by means of an intermediate vertical shaft and bevel-wheels fixed upon both the crank-shaft and the valveshaft. The said end plate can be removed to enable the shaft F, spindle H, and the cam and slide-block to be drawn out for inspection or repairs. The spindle II also projects from the end of the shaft F and is arranged to be moved to and fro, as before described, either by a hand-lever or other connection, or it may be connected with the governors and regulated bythem automatically,
to a slide-valve of a'steam-engine, and for starting, stopping, reversing, and regulating the cut-off consisting of a tubular slotted shaft F, an inclined key N, held within the slot, and secured to a sliding central spindle H, a cam M, through which the key N, can 20 move, and a slide-block L, encircling the cam M, and engaging with the valve as hereinbefore described and set forth.
2. As part of an arrangement of mechanism for operating the slide-valve of a steamengine, a cam M, having a central oblique opening m, the throw of the cam being varied by means of an inclined plate N, fitting into the said oblique opening, and secured to a spindle I-I, capable of being moved longitudinally, ashereinbefore described and set forth.
In witness whereof I have hereunto set my hand in presence of two witnesses.
SYDNEY WILLIAM WILKINSON.
