UNITED STATES PATENT OFFICE.
SIMON lEL BADGER, OF ERIE, PENNSYLVANIA, ASSIGNOR TO HIMSELF AND ROBERT FAULKNER, OF SAMEPLACE. V
IMPROVEM ENT INl SLIDE-'VALVE LUBRICATORS.
Specification forIriing part of Letters Patent No. 69,957, dated October 22, 1867.
To all whom it lmay concern:
Be it known that I, SIMON H. BADGER, of Erie, inthe county of Erie and State of Pennsylvania, have invented a new and Improved Self-Lubricator for Valves; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanyingdrawings', forming partofthis specification.
This invention relates toanew and improved self-lubricator designed for lubricating during the workingofthe engine the surfaces of steamvalves and valve-seats of locomotive and other slide-valves and the pistons working in the steam cylinders adjacent to the valves.
I n the accompanying sheet'of drawings, Fignre 1 is a vertical section of a steam-chest and slide-valve provided with my invention; Fig. 2, a longitudinal section of the same, taken in the line y y, Fig. 1; Fig. 3, a detached innerside or face view of the slide-valve provided with the invention.
Similar letters of reference indicate corresponding parts.
A represents the steam-chest ofthe cylinder of a steam-engine, and a is the exhaust, and b b the induction, ports.
B is the slide-valve, provided, as usual, with an exhaust-passage, a", in its under or inner side.
These parts, being of usual construction, do not require a special description.
The exterior of the valve B is provided with a cross-piece, O, in cach end of which there is a recess, c, aud these recesses communicate with tubes d d, which extend through the valve at each side of the exhaustpassage a* and communicate with oblong grooves e e, whichV serve as oil-receptacles (see Figs. 1 and 3) in the inner surface or face of the valve, which works over the valve-seat f, through which the ports a b b are made, as shown clearly inFig. 1.
D represents what may be termed a cap, which is a straight bar having a longitudinal groove, g, in its under side, to receive the crosspiece C ou the exterior. This cap is provided with a tubular stem, E, which passes through the top of the steam-chest, and a spring, F, is interposed between the cap and the top of the chest, to hold the cap steady and causeit to t snugly on the crosspiece (l. The stem E passes through a stuffing-box, G, in the top of the steam-chest, to prevent the leakage of steam therefromaround the stem.
On the top of the stem E there is screwed an oil-cup, H, having a stop-cock, I, at its lower end, by adjusting which the iiow ofoil into the stem may be regulated or cut oft' entirely, as desired.
The oil-cup H is provided with a tightly-tittin g cover,'h.
When the valve is in motion the oil passes from the yoil-cup through the stem E, the flow being greater or less as allowed by the stopcock I, and the oil passes into the recesses c c of the cross-piece C, as said recesses are alternately brought in line with the stem, the bil passing down through the tubes d d to the grooves e e and keeping the face of the valve and valve-seat in a perfectly lubricated state, as well as the interior of the cylinder.
The flow ot` oil from the oil chamber or cup H is insured by the partial vacuum produced under the motion of the valve and the advent of the steam intov the steam-cylinder and its escape or exhaust therefrom. The tightly-itting cover H, therefore, does not preclude the necessary iiow of oil, while it keeps the oilcup free from dirt, dust, and filth of all kinds, which would have a tendency to wear and abrade the working parts.
Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is
l. The combination of the cap D, tubular stem E, oil-cup H, cross-piece C, recesses c c, and passages d d, substantially as and for the purpose specified.
A2. The .grooves e ein the face of the valve communicatie g with the passages d d, substantially as shown and described, for the purpose specified.
3. The combination of the spring F, cap D, and top of the steam-chest with recesses c c Vand passages d d, substantially as described,
for the purpose specified.
The above specification of my invention signed by me this 24th day of June, 1867.
SIMON H. BADGER.
