UNITED STATES PATENT OFFICE.,

DELOS H. BUMPUS, OF EDENBURG, PENNSYLVANIA.

LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 233,323, dated October 19, 1880. Application tiled April 7, 1880. (No model.)

To all whom it may concern:

Be it known that 1, DELos H. BUMPUs, of Edenburg, in the county of Clarion and State of Pennsylvania, have invented certain new and useful Improvements in Oil-Cups or Lubricators; and I do herebyT declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, wlch form a part of this specification.

Figure lis a vertical section of an improved oil-cup, taken through 3 3 of Fig. 3, exhibiting the oil-discharge shell at its highest position and in communication with the oil-reservoir, part of the lever for operating being shown on the left-hand side. Fig. 2 is a vertical section ot' the same device, exhibiting theIoil-shell at its lowest position in communication with the lower discharge-bore, (which may connect with an engine or pump,) with the lever for operating the same shown in part on the right-hand side. Fig. 3 is a cross-section taken through lines l and 2 of Figs. l and 2, showing the lever in full in one position and in dotted lines in another position. Fig. 4 is an elevation ot' the stem and the perforations for receiving and discharging the lubricants, also the screw-thread for operating the oil-shell. It also shows, in section, the oilshell with its chamber in communication with the steam-escape pipe.

The object of my invention is to provide a lubricating-oil cup superior in mode ot' operating to those now used.

My invention consists of a reservoir, A, secured to a stem, B, solid in the center at C, and hollow at each end at D and D', which hollow ends are provided with perforations d and d. The upper part, D, has also a steamescape pipe, E, which extends upward beyond the mouth of the reservoir A.

On the center O of the stem B is the recessed screw-thread F, extending about halt'- way around it, `for the reception of the lug J, which forms part of the handle Ifor operating the shell.

Surrounding the stem B is an oil-shell, G,

for receiving and discharging the oil. Itis provided with stung-boxes g and g' on each end, which are provided with screw-caps h and p made steam-tight by asbestus or other suitable packing, (shown at i.) The shell G is movable on the stem B by means ot' the handle I, and the end J ot1 the handle I, engaging in the screw-thread F, causes the shell to rise or fall on the stem B, and thus communication from the chamber G' can at will be secured with the upper or lower part, D or D', ot the stem B. Ihe shell Gis thrown upward in position, as shown in'Fig. 1, to charge the chamber G' 5 but before arriving at the oil-ports d the confined steam, it'any, in G' escapes through the steam-escape pipe E, which is lower than the perforations el', and by the time the shell has reached its extreme height the steam has all escaped, and then the oilruns from the reservoir A through the ports cl into the chamber G'. The handle I is then thrown to its second position, the lug J traverses the screwthread F, and the shell G is forced down to the second position, as shown in Fig. 2. The ports d and steam-pipe E are thus closed and the ports d' opened, and the lubricant enters the lower bore, D', through the perforations d' and flows out into the engine or pump. With my improved oilcup or lubricator there is no inconvenience or trouble or loss of time in mode of operation. A simple turn of the lever in one direction throws the shell up for receiving the lubricant, and a turn in the opposite direction throws said chamber down for depositing or discharging the lubricant. 8 5

The operation ot' my device is almost instantaneous, and there is no splashing ot' oil, as all the confined steam escapes from the steamescape pipe E, and does not throw out the oil from the reservoir A.

What I claim as new, and desire to secure by Letters Patent, is-

1. An oil-cup or lubricator consisting, essentially, of a movable oil-chamber, which may at will be placed in communication with ports from an oil-reservoir, or with ports to the machine to be lubricated, substantially as shown and described.

2. An oil-cup or lubricator consisting of a suitable reservoir connected by suitable ports IOO to a movable oil-chamber, which, by a single with the movable shell G, substantially as 1o motion of a handle, will close one set of ports shown and described. and open another, substantially as shown and In testimony that I claim the foregoing as my own I aix my signature iu presence ot' described. 5 3. In an oillubrioator, the steam-escapes E, two witnesses.
