JAMES POWELL, OF CINCINNATI, OHIO.
LUBRioAToe.
SPECIFICATION forming part of Letters Patent No. 248,609,'dated October 25, 1881.
Application tiled September 2, 1878.
.To all whom it may concern Be it known that I, JAMES POWELL, of Oincinnati, Hamilton county, Ohio, have invented certain new and useful Improvements in Lubricators, of which the followiugis aspecitication.
This invention relates to those lubricators whose reservoirs are surmounted with a cup or bell-shaped receptacle, from which receptacle the oil or other lubricant iiows into the reservoir as soon as the screw-plug is elevated by rotating a hand-wheel or crank located above said oil-receptacle.
The irst part of my improvements comprises a novel construction ofthe lubricator, whereby, as the screw-plug is elevated from its seat to charge the reservoir with oil, the accumulated gases and steam are deiiected against the sides and inwardly-projecting rim of the cup, instead of being thrown out violently on the person ofthe engineer.
The second part of my improvements comprises a novelcombinatiou ot'devices, whereby I ain enabled to dispense withcliannels orgrooves or other oil-passages in the operating-stem ofthe screw-plug. rIhe oil-cup has a depending neck projecting into the reservoir, the lower portion ot' said neck being provided with a female thread, wherewith is engaged the male screw of the plug-stein, whose upper or exposed end carries a hand-wheel or other convenient rotating device. Situated between the screw and hand-wheel of this stem is a conical plug adapted to close against a suitable seat inthe cup or neck when the supply ot' oil is sluit ott', but as soon as it is desired to charge the reservoir said plug is elevated from its seat, and the lubricant then flows through lateral ports in the neck and tills said reservoir, as hereinafter more fully described.
In the annexed drawings, Figure I is an axial section of one forni of my lubricator, the plug being shown open and the discharge- Fig. 2 isa section of another form of the device, the screw-plug being disengaged from the reservoir. Fig. 3 is an enlarged sectional view, showing a key applied to the non-circular arbor ofthe disch argc-valve stem and Fig. 4 is an axial section ofthe upper portion of an old and well-known form ot' lubricator. Fig. 5 represents a modification of my invention. i v
The reservoir A, which may be of anysuitable size and shape, is furnished at its upper end.
with a cup or bell-shaped receptacle, B, which cup may be cast with said reservoir, as seen in Figs. l, 2, and 4, or it may be separate therefrom, as shown in Fig. 5, in which illustration said cup is represented as pro videdwith a male screw, bf' but, itn preferred, this cup may-,be connected to reservoir A with a female screw.
In the more complete form of my lubricator cup B has a marginal tlange or rim, b', as seen in Figs. 2 and 5, which rim is so shaped as to deflect steam and heated gases inwardly when the screw-plug is rst elevated from its seat, preparatory to charging reservoir A. This inward deiiection of such vapors may be assisted by imparting to the walls of said cup the shape shown in Fig. 5, or any eective approximation to this shape. Furthermore, the center of cup B is counterbored at b to serve as a seat for the screw-plug, said seat being located at the upper end of a depending neck, C, screw-threaded interorly at c, and pierced above the latter with one or more apertures or ports D.
Adapted to engage with thread c is the male screw E of stem F, whose conical plug` G seats in counterbore b when it is desired to close cornmunication between reservoir A and cup B.
H is the haiid-wheel or other rotating device of stem F.
I is the discharge-channel of reservoir A, and. J is the controlling-valve ot' this channel, said valve being furnished with a screw-threaded stem, K, whose outer end terminates with a square or other non-circular arbor, L, adapted to receive the key or socket-wrench M, as seen in Fig. 3. This arbor L is housed within the chamber or bore a of prolongation N of the stuffing-nox cap O, which prolongation may be cast in one piece with said cap, or it may be screwed to the same.
P is the packing around stem K.
The plug-stem F has a flange or collar,f, that tits into a recess, h, on the under side of handwheel H, which latter is pierced at R R to receive stumps S Sot said flange,as seen in Fig. 2. Furthermore, this wheel is recessed on its upper side at h to admit a disk, T, which is se IOC cured in position by a screw, U, tapped into the upper end of plugstem F. By this arrangement the hand-wheel and plug-stem are securely united together.
To charge my lubricator, valve J is closed, and stem F is rotated so as to elevate the plug G from its seat b, as seen in Fig. 1, after which act oil is poured into cup B and tlows through ports D into reservoir A, the plug being again screwed down onto its seat as soon as said reservoir is filled. Key M is now inserted in chamber n and applied to arbor L, so as to adjust the discharge-valve J in such a manner as to deliver the proper quantity of lubricant when the key is disengaged from said arbor. As
l this arbor is housed within chamber n, it is evident stem K cannot be rotated by any person except the custodian of the key, and consequently the flow of oil can be maintained with the utmost regularity and certainty.
If preferred,the arbor L may be omitted. and stem K may have a square or non-circular hole in it to receive a suitable shank of key, M, or the outer end of said stem may be slotted to admitaserew-driveror otherhandyimplement.
l am aware that a lubricator with an external or upwardly-projectin g neck, as seen in Fig. 4, is not new, and therefore my claim to the charging appliances of the device is expressly limited to the stem F, whose plug Gr is situated above the screw E, and is adapted to seat within the counterbore b ofthe internal depending neck C c D, as herein described.
I claim as my invention- 1. An improved lubricator consisting of the oil-cup B, having an internal depending neck,
