Application filed September 30, 1920. Serial No. 413,773.

To all whom it may concern Be it known that I, WILLIAM HENRY LINDENFIELD, a citizen of the United States, and a resident of Lexington, in the county of Henderson and State of Tennessee, have invented certain new and useful Improvements in Oil-Cups, of which the following is a specification.

My invention is an improvement in oil cups, and has for its object to provide mechanism in connection with oil cups of the Hancock inspirator type for preventing ac: cidental displacement of cover and feed valve, due to jars from the machinery upon which the cup is used.

A further object of the invention is to provide mechanism in connection with the valve stem, for locking said stem to permit the feed to be regulated.

In the drawings:

Figure 1 is a side view of the improved cup, 4

Fig. 2 is a vertical section,

Fig. 3 is a topplan view of the cup,

Fig. 4 is a bottom plan View of the cover,

Fig. 1? is a detail section showing the feed stem, 7

Fig. 6 is a top plan view of the cover,

Fig. 7 is a bottom plan view of the cover,

Fig. 8 is a side view of the valve stem of the embodiment shown in Figs. 5 to 7, the top being in section,

Fig. 9 is a top plan view oi: the top.

In the embodiment of the invention shown in Figs. 1 to 1, the cup comprises a body 1 which is reamed or flared at its upper end, 7

as indicated at 6, the flaring portion of the bore being in an inward extension of the nipple, the said nipple being extended above the bottom of the cup body. This flaring portion 6 is a valve seat with which 005* erates with the tapered portion of a needle I valve 7, the said valve having threaded engagainent with a nut 8 supported by the top 14- oi the cup. This needle valve has a cup shaped extension 9 at its top, and the extension has a pair of oppositely extending cars 10, the body of the cup-shaped extension being coaxial with the valve.

The cover of the oil cup consists of a central portion 11 and radial extensions 12, the said extensions extending in opposite directions and being designed to cover are shapedopenings 13 in the top 14: of the cup. These openings are oppositely arranged and the extensions 12 are, as before stated, shaped to cover and close the openings.

The cover ll has a central nipple 15 extending on both sides of the cover, andthe nipple is of greater diameter than the threaded portion of the valve 7 which it encircles,an inwardlyextending rib 16being provided. for engaging the valve to center the same. A coil spring 17 is arranged between the cupshaped extension 9 of the valve stem and the rib 16, and this spring acts normally to press the valve upwardly.

The cup shaped extension 9 has cars 10 for convenience in turning the same and by turning the valve, it will be evident that the extent of the opening through the passage 5 may be varie In order to prevent accidental displacement of thecover 11, I provide in the under face of the cover at points'directly opposite to each other'rounded lugs 18 in the form of balls which are embedded and held in openings inthe cover 11, and these balls are adapted to engage recesses 19 in the central portion of the top of the cup. The action ofthespring 17 normally holds the balls in engagementwith the recesses 19, but by lifting up on thecover or by merely turning the cover the balls may be released thus acting to turn or force the. cover outwardly toward the extension. The cover is also provided on one of the extensions 12 with a depending lug 20, and this lug is adapted to engage a notch or recess 21 in the' top of the oil cup when the balls 18 are in engagement with-the recess 19.

In Figs. '2 and 1, there is shown mechanism for preventing accidental displacement of the feed stem, and to lock said stem in adjusted position.

the slot extending from about the lower end of the extension 9 to below the threaded portion of the stem, and above the rib 16 before mentioned.

V This mechanism comprises a slot 7 a 1n the needle valve stem,

Looking pins 8 and 8 are arranged in this slot, the pin 8 being below the rib 16, while the pin 8 is above the said rib. The pin 8 is adapted to engage notches 9 in the lower end of the cover nipple 15, and the pin 8 is adapted to engage notches 9 in the upper face of the rib 16. 7

Each series of notches 9 -rand 9 is four in 7 number, and the pins 8 and 8 are held in in the slot 7*.

In Figs. 5 to 9 there is shown a construc tion wherein the cup 21 is "similar to the cup 1 of Fig. 1,;having the are shaped openings' 22 in its top for permitting theinser- :tion of lubricant, and at each side of the 7 central opening for the :valve 23 there is provided the recesses 24 corresponding to the recesses 19 of Figs. 1 to 1. These recesses are adapted to be engaged by balls 25 held inthecover 26, which is similar to i the cover 11,- having similar radial extensions for closingthe openings 22. A lug 27 is secured to the under face of one of the extensions'at the center thereof, and this lug'is adaptedto engage a notch 28 in the upper edge of the body of the cup at the center of one of the openings 22. I

The cup shaped top 28 of the valve corresponds to the cup shaped extension, or

squared on both sides, and is inthe present instance, not rigid with the valve, but is mounted to slide thereon up and down. The

, valve stemhas a head 29 which isfprovided with oppositely extending cars 30, and these cars 30 extend below the head 29 as wellas above, and provide means for engaging radial notches 31 in the cup shaped member 28. With this arrangement, the valve stem is "locked against displacement, the spring '(not shown) corresponding to the spring 17 holding the cup shaped member 28 in-engagement with the ears 30 as well as holding the cover 26 in locked po sition on the cup. V

In either construction, the top or cover of the oil cup is held from accidental displacement by the balls "and the recesses, as well as by the lugs and the notches. In the construction ofFigs. 5 to 9, the valve stem is also looked against accidental release, itbeing necessary to depress the cup shaped member 28 @bcforeflthe valve stem can be turned. The depression, however, may be brought about by the turning of the stem, additional force being necessary to overcome the resistance of the spring.

An oil cup having in the top thereof oppositely arranged openings for permitting the insertion of lubricant, and a cover mounted to rotate in the cup and having radial extensions fitting over-the openings for closin the same and releasable lockin b 7 V b means between the cup and the cover released by forcible turning of the cover, a valve in connection with the cup for controlling the flow therefrom, said valve passing through the top of the cup and through the cover, a cup shaped member in connection with the outer end of thevalve,ra spring arranged between the said cup shaped member and the cover and normally pressing the cover to its seat, the valve having a head engaging outside of the cup shaped member,

and releasable locking mechanism between the member and the head. 1 v
