EDWARD J. MCGUIRE, OF LUMBERTON, NORTH CAROLINA.

LUBRICATOR.

Specification of Letters Patent.

Patented Nov. 17, 1908.

Application filed April 11, 1908. Serial No. 426,515.

To all whom it may concern:

Be it known that I, EDWARD J. MCGUIRE, a citizen of the United States, residing at Lumberton, in the county of Robeson and State of North Carolina, have invented new and useful Improvements in Lubricators, of which the following is a specification.

This invention relates to improvements in oiling devices of that class known as sightfeed and by which the supply of the lubricant can be accurately regulated and wherein the parts are adjustable and readily operative to cut oif the oil or to supply the required quantity of oil, according as the engine or other part or mechanism to be lubricated may require.

The object of the present invention is to simplify oiling devices and render them efi'ective in their operation as well as to combine in one device oil filtering and feeding means of an efficient character, the several parts of the oiling device orlubricator being readily associated or separated for convenience in manufacture and application and cleaning and repair purposes.

The invention consists in the construction and arrangement of the parts which will be more fully hereinafter specified.

In the drawing: Figure 1 is a transverse vertical section of an oiling device or lubricator embodying the features of the invention. Fig. 2 is a top plan view of the same. Fig. 3 is a horizontal section on the line -33, Fi 1.

gimilar characters of reference are employed to indicate corresponding parts in the several views.

The numeral 1 designates an oil cup of any suitable construction, but preferably comprising a transparent body or cylinder 2 with an upper closing cap or head 3 fitted thereover and a lower or base cap 4. Suitable packing means will be interposed be tween the terminals of the body or cylinder 2 and the caps for a purpose which will be readily understood. Rising from the center of the base cap 4 and preferably formed therewith is a feed tube 5 having a lower extension or outlet nozzle 6 depending from the center of the cap 4.: and an upper screwthreaded extremity 7 over which the cap'3 is fitted, the said cap 3 being held down in place on the body or cylinder 2 by a clamping member having an inner extremity 8 resting on the top of the said cap and engaging the screw-threaded extremity 7, and also provided with an outwardly projecting handle 9 by means of which the said clamping member may be operated. Over the inner extremity 8 of the clamping member a nut 10 is applied to the screw-threaded extremity 7 of the feed tube and serves as a set device or element to prevent loosening of the parts.

The feed tube 5 has a bore 11 extending centrally therethrough and formed with an upper screw threaded portion 12 and a lower constricted continuation 13 projecting through the nozzle 6. The upper extremity of the constricted continuation 13 of the bore is adapted to be engaged by a needle valve 1% continuous with a rod or stem 15 which gradually increases in diameter to a maximum diametrically enlarged portion 16 which is screw-threaded to engage the screwthreads 12 in the upper part of the bore 11. The stem or rod 15 continues above the upper terminal of the feed tube 5 and has an adjusting lever 17 movably connected thereto and adapted to engage notches or peripheral seats 18 formed in the cap 3, as clearly shown by Fig. 2. By turning the rod or stem 15 through the medium of the lever 17, the needle valve 14 may be raised or lowered to control the feed of the oil through the nozzle 6. The feed tube 5 is also provided with a plurality of feed openings 19 communicating with the upper portion of the feed cup and the bore 11 and through which the oil passes from the cup into the bore of the feed tube. The nozzle 6 is externally screw-threaded as at 20 and thereover is applied the upper end of a combined sighting and securing member 21 having a lower externally screw-threaded tubular component 22 which is shouldered for convenience in applying the oiling device or lubricator to an engine or mechanical element adapted to be lubricated, and with which it is desired that the lubricator perform its function. The member 21 adjacent to the lower outlet terminal of the nozzle 6 has a glass cylinder 23 fitted therein and exposed by opposite openings 24 so that the oil dripping from the nozzle downwardly to the component 22 may be readily seen from the exterior of the lubricator and serve as means for guiding an operator in determining the amount of oil fed to the engine or mechanical element lubricated.

An oil supply tube 25 is formed continuous with or as a part of the feed tube 5 and terminates adjacent to the bottom of the cup, the upper extremity 26 of this supply tube being laterally deflected and projected upwardly through and extended above the cap 3, the clamping member 8 serving as a cover means for the upper inlet end of this supply tube and having a handle 9 broad enough to perform the function of a closing device. WVhile the clamping device is effective in holding the cap 3 down in place when engaged by the nut 10, it will be understood that this function is secondary to the more important service as a closing means for the upper inlet extremity of the supply tube 25. Suitably brazed on or otherwise secured to and surrounding the feed and supply tubes 5 and 25 below the lowermost feed opening 19 is a canopy or defiector 27 which is of less diameter than the interior of the cup, but has sufficient outward extent to serve the purpose for which it has been devised. A tight joint is formed between the canopy or deflector 27 and the feed tube and supply tube, and said defiector is imperforate and has an upper downwardly inclined surface 28.

In preparing the oiling device or lubricator for service a quantity of water is disposed therein and extends up over the canopy or deflector 27. A. supply of oil is then introduced through the tube 25 and owing to its lightness as compared with the water, passes upward or filters through the latter and is sustained on the surface of column of water, the oil being delivered within the cup near the base of the latter and being freed of impurities or sediment such as grit in fine particles when passing upwardly through the column of water. If the oil is not fully freed from sediment or grit when passing upwardly through the column of water, such sediment or grit will gravitate from the oil onto the upper inclined surface 28 of the canopy or deflector 27 and from the latter will gradually work downward into the column of water and be deposited against the base cap 4. The cup may be cleaned or relieved of sediment as well as the column of water through the medium of a drain cock 29 secured to the cap 4 as shown by Fig. 1. The oil after it has been cleansed or filtered passes through the openings 19 into the bore 11 of the feed tube 5 and from the said bore is fed through the nozzle 6 in accordance with the adjustment of the needle valve 14.

The oil in filtering upwardly through the column of water is forced to pass around and over the periphery of the canopy or deflector 27 in view of the fact that there are no openings in the said canopy or deflector, and hence the oil will become more thoroughly filtered or cleansed.

The improved oiling device or lubricator will be found especially advantageous in its operation, and such changes as to proportions, dimensions and minor details may be adopted as fairly fall within the scope of the invention and to adapt the lubricator for application to different mechanisms.

Having thus fully described the invention, what is claimed as new, is:

1. In a lubricator, an oil feeding tube extending downwardly therethrough and also provided with a filtering column of liquid in its lower portion, a deflector surrounding the feeding tube and submerged in the said column of liquid, and means for supplying oil to the cup below the deflector.
