SPECFICATION forming part oi' Letters Patent No. 326,521, dated September 15, 1885.

(No model.)

To all wiz/0m it may concern:

Be it known that I, JAMES POWELL, a citizen of the United States, residing at Oincin nati, in the county of Hamilton and State of Ohio, haveinvented certain new and useful lmprovenients in Lubrieators, of which the fol` lowing is a specification, reference being had therein to the accompanying drawings.

This invention relates to those lubricators which employ an axial rod, stem, or plug for operating the valve or cut-off that regulates the discharge ot` oil; and my improvement consists in utilizing the upper or outer end ot' the valve-stem as a guide for a reciprocating stopper, which latter, when depressed, permits the cup or reservoir to be tilled. Said stopper plays within a slotted 01 perforated cage or cylinder, and is maintained in its elevated or closed position by a spring that is preferablylocated within said cage and coiled around the valve-stem, the ascent of the stopper being arrested by the th u nib-piece or other lateral projection of said stem. Furthermore, this cage and a spindle thereof act as a tie or binder that unites the two heads ofthe cup, and said spindle or prolongation is usually pro vided with a valve'seat, dischargechannel, and one ormore ports that allow the oil to i'low into said channel when the. valve is opened. The abovedescribed devices are so arranged as to enable the ready depression of the stopper by pressure applied externally of the same, after which act t-he oil can be conveniently poured into the open end of the cage and tlow through the slot-s or openings of the same into the cup or reservoir, as hereinafter more fully described.

In the annexed drawings, Figure l is a side elevation of my improved lubricator. Fig. 2 is an axial section thereof, the discharge-valve being closed, and the reciprocating stopper being shown in its normal or elevated position. Fig. 3 is an axial section of the upper part of the lubricator, said stopper being depressed. Fig. 4 is a transverse sect-ion of the cage, the valve-stem, stopper, and spring being removed therefrom. Fig. 5 is a plan ot' the under side of said stopper.

The oil cup or reservoir A, which is usually of glass, has a lower head, B, and an upper head, C, which latter is provided with an oritice, c, to receive a cage, D, that is generally of a cylindrical form,and is furnished with one or more slots, perforations, or other openings or passages, d, communicating with the interior of said reservoir. The upper end of the cage is open and has an enlargement or collar, E, that rests upon the head O, said enlargement being preferably made in the shape of a nut to facilitate the clamping of the heads B C to the cup; but the lower end of the cage is closed by a head, d', from which projects a spindle, F, having an internal thread, f, an external thread, G, one or more lateral ports, H, and a discharge-channel, I.

Engaging with the thread f' is the screwj of a stem or rod, J, the latter having at its lower end a valve, K, and at top a thumbpiece, L, or other suitable device, wherewith said stem can be conveniently manipulated.

Adapted to reciprocate within the cage D is astopper, M, provided at its outer end with an elongation er neck, N, the latter having an axial bore, n, to admit the valve-stein J. The top ot' this neck terminates with a bead or colla-r, n', that affords a convenient bearing for the ringer when the stopper is toV be def pressed. n

Interposed between the stopper M and the head d of the cage is a coiled spring, O, whose stress elevates said stopper and keeps its col.- lar n/ in Contact either with the thumb-piece L or other stop of the valve-stem. The upper coil of this spring iits within an annular groove, m, on the under side of the stopper, which latter is notched on its edge at m to permit a free escape of air while the reservoir is being iilled.

If desired, the above-described devices may be used in connection with a lubricator having a sight-chamber, in which event the external thread, G, of the spindle F would be engaged with the internal thread, p, of the lower section, P, and the latter would be furnished with a channeled shank, R r, for attachment to the journal-bearing. Furthermore, this lower section should have an external screw, S, to engage with an internal thread, b, of the lower head, B, in order that the sight-chamber T may be securely clamped between said section and head.

It is evident that when the lubricator is properly ttted together the stress of spring O will force the stopper M up so far as the stop IOO L will permit, as seen in Fig. 2, thereby closing the mouthof cage D and preventing dust or other obstructions entering the oil-cup A.

As soon, however, as it is desired to charge 5 said cup with oil or other lubricant, the stopper M is shifted by simply pressing the end of the linger against the colla-r n', and when the stopper has been forced down as far as may be necessary it reaches a position somewhat below the upper ends of the slots or perforations d, as seen in Fig. 3. The oil can now be freely poured into the upper open end of cage D, and being unable to descend directly, on account of the obstruction aiorded by the stopper, it is deflected laterally and runs through the slots or openings d into the reservoir A, the air in the latter escaping at the groove m. As soon as the reservoir is filled, the finger is removed from the collar n', and the spring O immediately restores the stopper to its normal orvclosed position, 4the extended bearing of the neck N on the valvestem J causing said stopper to travel in a correct path and preventing it binding within the cage D d. After charging the reservoir the stem J can be turned so as to raise the valve K a greater or less distance from its seat at the upper end of the channel I, thereby regulating the discharge of oil.

From this description it will be apparent that the stem J serves the twofold purpose of operating the discharge-valve and acting as a guide for coniining the reciprocating stopper to a proper path.

I claim as my invention- I 1. The combination, in an oil-cup, of aA continuous or uninterrupted rod or stem for controlling the discharge of lubricant with a spring-actuated stopper adapted to recipro- 40 cate along the upper portion of said stem and uncover one or more inlets, the lower portion l ld rod-stem being screwed into a suitable l and its upper end being passed comthrough said stopper, thereby serving id guide for the latter, and permitting the stem to be removed without detaching the stopper, substantially as described.

2. The combination, in an oil-cup, of a continuous or uninterrupted rod or stem for controlling the discharge of lubricant with a 5o spring-actuated stopper adapted to reciprocate along the upper portion of said stem and uncover one or more inlets, and an inclosing cage or cylinder, the lower portion of said stem being screwed into a. suitable bearing, and its upper end being passed completely through said stopper, thereby serving as a rigid guide for the latter, and permitting the stem to be removed Without detaching the stopper, substantially as described. l

3. The combination, with an oil-cup having a rod or stem controlling the discharge of lubricant, of a spring-actuated stopper adapted to reciprocate along said rod and within a cage-or cylinder and uncovers one or more inlets of said -cage when properly shifted, said cage being provided with the valve-seat and outlet and serving as a tie that clamps the heads to said cup, substantially as herein described.

4. An improved lubricator consisting of the oil-cup A, having a head, B, screw-threaded at b, and a head, C, having an orifice, c, the cage D, having one or more passages, d, head d, and spindle F, which latter is provided with interior thread, f, inlet H, dischargechannel I, and a seat for the valve K of stem J, said stem being furnished with a. screw, j, that is adapted to engage with the thread f of the spindle, and having a suitable stop, as L, for the reciprocating stopper M, which stop- 8C per is bored at n to admit the stem J, a spring,

O, being interposed between said stopper'and the head d of the cage, for the purpose speciied.

In testimony whereof I aix my signature `in presence of two witnesses. A l
