Description

UivrrE-D STATES' SIMON SMITH AND ISAAC S. COLLINS, OF MAUCH CHUNK,PENNSYLVANIA.
PATENT Grrrcn.
iMpRovEMENT IN LuBRlcA-roRs.
Specification forming part of Letters Patent No. S0,6 66, dated August 1, 1 876; application filed May 27, 1876.
, fied forni of the feeder; and Figs. 4, 5, Vand 6,
respectively, detail views of cap base., and sliding disk of the modified shape of feeder.
Similar letters of reference indicate corresponding parts. Y p The object of our invention is to furnish an improved horizontally-feeding oil-cup or lubricator for connecting-rods, cross-heads, guides,
eccentrics, and other vparts of steam-engines, which can be regulated to feed a greater or less quantity of oil when the engine is in moy tion, but which discontinues the oilsupply vwhen the engine is stopped.
y The lnbricator is not liable to get clogged by dirty oil, avoiding thereby the expense for repairing hot pins,
The invention consists of a horizontal cup of cylindrical shape, with tightly-seated glass heads. The feeding mechanism consists of ahorizontallyfreciprocatin g pin or disk, guided in suitable manner, and having recesses ,or grooves that take up the oil from supply perforations or grooves and convey it to the feedtube at each oscillation of the part of the engine to which the lubricator is attached.
In the drawing, A represents a feed-cup of cylindrical shape, that is applied in horizontal position to the part of the locomotive or other engine to be lubricated.
The cylinder Ais tightly closed at both ends by washers and screw-heads B, that are preferably made of glass,.with guard-pieces, to indicate readily and distinctly the quantity of oil at any time in the cup. The cup is filled by a feed-openin g, a, at the top, which is closed by a screw-plug, b.
The oil is fed by a feeding mechanism, C, at the bottom of the cup to the feed-tube D, to
and securing a reliable and economical feed of oil.
which the feeder C is screwed or otherwise attached. shape of a grooved cylindrical pin, d, that slides .in a horizontal guide-casing, c, as in Figs. l and 2, or in the shapeof a disk, d, that slides in a cylindrical casing, e, as shown in Fig. 3. A
When the feeder is in the shape ofa pin the longitudinal axis of cup and feeder -is placed in the direction of motion of the part to which the lubricator is applied, the pin being set into motion by the oscillations ofthe engine.
The diskshaped feeder maylbe applied in horizontal position Without reference to the direction of motion, it being operatedin the same manner by the oscillatory motions of the engine parts.
The motion of the sliding pin d is dened by a top`slot, f, and guide-pin j of set-screw f 2, and the oil fed to bottom recesses, slots, or annular grooves d of the pin d through bottom holes el, that are at a distance equal to the length of sliding motion of the pin. l
The disk-shaped feeder is supplied with oil through side holes of its casing, being vguided by a top pin, f, in a circular recess, f1, of its cap, and taking up the oil from acircular bottom groove and holes, c2, concentric to and at equal distance from the perforation of the feed-tube at the bottom recesses of the disk.
-The motion of the pin or disk in either direction conveys a small quantity of oil that hascbeen taken up by the recesses of the pin or disk to the feedtube, feeding quicker or slower, according to the speed of the engine. When the engine is stopped the pin is at rest in the sleeve, and discontinues entirely any supply of oil, as there is no possibility of leak-l ing,'as in vertically-oscillating feed-pins.
The amount of feed is regulated by the size of the recesses or grooves, and the clogging of the feedpin prevented by the sliding motion of the same, which tends to push any dust or other impurities of the oil to the outside of the sleeve, so as to exclude it from entering between the pin and sleeve.
The reliable feeding of the pin when the engine is in motion, together with the interruption of the feed when the engine is at rest, provides an economical lubricator, While the The feeder C is made either in the non-liability of the same to interruptions by dirty oil occasions less expense for repairs, and keeps up a regular and perfect action ot' the feed-cup. The feeding` deviee may be applied to any shape ot' cup, and utilizes nearly the entire quantity ot' the same, as the feed meehanisn'l may be arranged close to the bottom of the. cup.
Having thus described our invention, We elaim as new and desire to secure by Letters Patent-
