The invention relates to oil cu'psof the gravity feed type and has for its object to provide within the cup an auxiliary cup having filtering means in the lower end 1'5 thereof and spring means for normally forcing said auxiliary cup upwardly for maintaining the upper marginal edge of the auxiliary cup in close engagement with a single washer interposed between the'cap. and

the oil cup casing, thereby utilizing a sin gle washer for forming a seal between the cap, cup casing and auxiliary cup.

A further object is to provide the lower flanged base of the cup with an upwardly 1 extending stem extending through the cap and having threaded on its upper end a nut, which nutforms sole means for forcing the cap downwardly into close: engagement with the washer. V

A. further object is to fiare the upper end of the auxiliary cup so that its upper marginal edge will engage the washer when the auxiliary cup is forced upwardly by the spring.

A further object is to provide a coiled spring beneaththe auxiliary cup, and form- .ing means whereby upon removal of thecap, said auxiliary cup will be forced upwardly to a position above the main cup where it 3 can be easily grasped for removal.

A furtherobject is to provide the lower end of the auxiliary cup with a perforated disc or screening means a filtering material on said disc for screening or filtering finer particles from the lubricant, an expansible ring above the filtering material and a per forated disc supported in the ring for screeni in the coarser particles from the lubricant. JWith the above and. other objects in View 4 the invention resides in'theecombination and arrangement of parts as hereinafter set forth shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention maybe made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing:

Cups

.can easily regulate the discharge of in washer is utilized'as a sealing means betweer Figure 1 is a view in elevation of the oil CUP 1928. Serial No. 278,213.

downwardly from the base 1 is an extension 5 adapted to be threaded intoa bearing opening or the like for discharging lubricant through the lubricant passage 6; Extending upwardly from the base 1 is an integral axially disposed tubular member 7, in which is threaded at 8 the needle valve stem 9. the valve end 10 of which-cooperates with the valve seat 11 .forregulating the amoun'; of lubricant allowed to enter the passage 6 Lubricant enters the tubular member 7 7 through the port 12 adjacent the base 1, therefore it will be seen that the "1 o? cant by rotating the finger engaging member 13. The finger engaging member is helf in adjusted position by means of a spring arm 14 carried by the tubular member 7 and frictionally engaging the periphery of the member 13. i

Disposed within the casing 4 in space l re lation thereto is an auxiliary casing 16. the upper end'of which is preferably fia'ed as at 1? tea position where it is relatively close to the upper end of the main casing l so it will engage the under side of the single annular washer 18, which is interposed be tween thei upper end of the casing 4: and the cap 19, therefore it will be seen that a single the casing t, the auxiliary cup16 and the 5 cap 19. By this construction the number of parts are reduced to a minimum and it is only necessary to use the single washer 18.

Rotatably "mounted on the upperend of tabular member 7 and an the cap 1951a a closure 20, which normally closes a filling opening 21 in the cap, and threaded on the tubular member 7 is a nut 21, which when tightened forces the cap 19 downwardly into close engagement with he washer 18 for forming a leak proof connection, however it will be noted when disassembling the device, it will only be necessary to remove the needle valve and the nut, and at which time the auxiliary cup 16 will be forced upwardly by the coiled spring 22 interposed between the bottom of the cup and the base 1, and said cup will be forced upwardly to a position where it can be easily grasped for removal purposes.

The bottom of the auxiliary cup 16 is provided with a perforated disc 23, on which is disposed a filtering material 2%, preferably felt, and which filtering material is held in place by an expansible ring 25, which ring also supports a perforated disc 26. The disc 26 forms means for screening from the oil relatively large foreign matter, and the filtering material2l filters finer particles from the oil. It will be noted that as the oil passes through the filter in the auxiliary cup 16, it will be screened, and the oil will assume a level in the main casing l, which is formed from transparent material, there fore it will be seen that the level of the oil in the cup may be easily ascertained, par ticularly as the auxiliary cup 16 is in spaced relation to the main casing 4, thereby allowing-the lubricant to rise between the cup 16 and casing 4. The upper end of the auxiliary casing 16 is provided with an air port 27 whereby air may pass to and from the interior of the auxiliary cup 16 for allowing the lubricant to assume a level by gravity without air binding.

Extending upwardly from the perforated bottom 28 is a sleeve 28 which surrounds the tubular member 7 and terminates adjacent the upper end of auxiliary cup 16 and forms means for accurately guiding the auxiliary cup 16 under the influence of the expansion spring 22, as well as under the influence of the cap 19 when forced downwardly to closed position.

From the above it will be seen that an oil cup is provided of the gravity feed type, wherein an auxiliary cup is used having filtering means for the oil before it enters the main cup, a single washer is used as a sealing means between the auxiliary cup and the main cup and the cap and upon removal of the cap spring means is provided which will force the auxiliary cup upwardly to a position where it can be easily grasped for removal purposes for cleaning and the like, and said auxiliary filtering cup being placed in theoil cup in spaced relation theretoso that the height of oil in the cup may be o ved- The invention having been set forth, what is claimed as new and useful is:

1. A combined oil cup and filter comprising a main casing, a filter cup within the main casing in spaced relation thereto and discharging into the main casing, an annular washer carried by the upper end of the main casing, a flared flange carried by the upper end of the filter cup and engaging said washer, spring means for forcing the filter cup into engagement with the washer, a cap carried by the main casing, and means for forcing said cap into engagement with said washer.

2. A combined oil cup and filter comprising a main casing, a filter cup in the main casing in spaced relation thereto, an axially disposed extension carried by the main casing and extending upwardly through the filter cup, a valve in said extension controlling the fiow from the main casing to a dis charge port, a coiled spring surrounding the extension and interposed between the main casing and the filter cup, .a cap carried by the upper end of the main casing, a single washer interposed between said cap and the upper ends of said casing and the filter cup, a nut threaded on the extension, said nut cooperating with the cap whereby it is forced downwardly into engagement with the washer.

8. A combined oil cup and filter comprising a main casing, a filter cup in the main casing in spaced relation thereto, straining means carried by the filter cup and through which oil passes to the main casing, an extension carried by the main casing and extending axially through the filter cup and on which the filter cup is axially mounted, a coiled spring surrounding the extension and interposed between the main casing and filter cup and normally forcing the same upwardly, a cap carried by the main casing, a single washer interposed between the cap and the upper ends of the main casing and the filter cup, and a nut threaded on the extension and cooperating with the cap for forcing the same downwardly into engagement with the main casing, said coiled spring forming means for maintaining the upper end of the filter cup in engagement with the washer.

4. A combined oil cup and filter comprising a main casing, a filter cup within the main casing in spaced relation thereto and discharging into the main casing through perforations in the bottom of the filter cup, there being a peripheral oil chamber between the wall of the filter cup and the wall of the main casing, a filter element supported by the perforated bottom of the filter cup, a perforated metallic screen on the upper side of the filter member, an annular washer carried by the upper end of the main casing, a flared flange carried by
