IMPROVEMENT IN LUBRICATORS.

Speciiication forming part of Letters Patent No. 213,589, dated March 25, 1879; application filed February l, 1879.

To all whom it may concern:

Be it known that I, CHARLES H. PARsHALL, of Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Lubricators; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in lubricators. Eeretofore,in lubricators wherein the oil is fed automatically by the superior gravity of v water of condensation, the oil is displaced and moved to the oileduction outlet of the lubricator by the superior weight or gravity of the condense water, the latter entering the oil-receptacle and displacing a corresponding quantity of oil, and causing the latter to be expelled from the oil-receptacle and fed to any desired point.

The object of my invention is to provide a lubricator of such construction that the oil may be fed by its superior gravity, due to a sufficient head of oil-supply to cause the oil to iow upwardly through a column of water to the point of discharge; and to this end my invention consists in the several details in construction and combinations of parts, as will hereinafter be described, and pointed out in the claims.

In the accompanying drawings, Figure l is a vertical section of my improved lubricator. Fig. 2 is a detached view of the steam -pipe and check-valve located therein, and Fig. 3 is a transverse view of the stem of the checkvalve.

A represents the steam -pipe to which the lnbricator is to be attached. B is the stem of the lubricator, and is provided with independent passages C and D. To the upper side of the stem B is secured an oilreservoir, E, which is preferably made of metal, although it may be constructed of any desired material. The upper end of the oil-reservoir E is furnished with an oilinduction opening, a, through which oil is supplied to the reservoir, said openin g a being closed by a screw-threaded stopper, b, after the reservoir has been filled.

Cups F F are cast solid with the reservoir E, and are located near opposite ends of the same, and receive the opposite ends of the glass indicating-tube G therein. H is a screwthreaded plug, provided with an interior chamber, c, and a passage, d, formed through the chambered portion of the same. Passage tl connects with a passage, e, communieating with the interior of the oil-reservoir. Packing-rin g or gasket f is fitted around the upper end of the tube Gr, and when the lower end of the screw-threaded plug H is turned down snugly upon the packing-ring a tight joint is formed between the glass tube and its supporting-cup, while afree passage is formed through the plug, establishing a direct communication between the oilreservoir and upper end of the glass tube G. The lower end of tube G extends through the bottom of supporting cup or flange F', and is retained in place by the screw-threaded plug I, the end of which rests upon a packing-ring, g, surrounding tube G. Plug I is provided with an i opening, h, which connects with apassage, z', leading to the interior and lower port-ion ot' the oil-reservoir. A waste-cock, K, is secured to the lower end of plug I, and connects with the inner chamber, j, of said plug by means of a passage, k, formed therein. By opening the waste-cock the oil and water in reservoirE may be drawn off when desired.

L is a steam-tube, the lower end of which is screwed int-o the stem B of the lubricator, and connects with the steam-passage C. The upper end of steam-tube L extends nearly to the top of the oil-reservoir, and is provided with a valve-chamber, k', which is furnished with a conical valve-seat, Z. Within valvechamber lo is located an upwardlyelosin g conical valve, M, having a stem, m, which projects through the opening m1 in the upper end of the valve chamber, and which serves to guide the valve to its seat. As the steam enters the passage C and ilows into the steamtube L the force of the steam, acting against the Vface of the conical valve, raises the latter snugly against its seat, thereby preventing the escape of steam into the oil-reservoir E.

The following provision is made to admit steam into the oil-reservoir for the purpose ot' forming condense-water to feed the oil to 111e point to be lubricated. The lower end of the screw-threaded stopper b is recessed at m2 for the reception of the upper end of the valvestem.

In Fig. 3 is illustrated the form of valvestem m in cross-section, it being triangular or of any equivalent form, so thatwhile the valve is guided steam is allowed to tiow past the stem into the oil-reservoir. hen it isdesired to admit steam to the oil-reservoir, by simply turning the screw-stopper b downward the valve is forced away from its seat, and steam rushes past the valve and through the steampassagcs on the sides of the valvestem into the oil-reservoir. rl`he amount of steam-open ing may be regulated with the greatest accuracy,so that any desired amount of steam may be supplied tothe oil'reservoir, the adjustment being effected by varying the height of the lower end of screw-stopper I.

N represents an oiltnbe. which extends upwardly into the oil-reservoir, the upper end of tube N heilig below the upper end ofthe steamsupply tube, whereby there is formed a condensing-chamber, N', above the top of the oilsupply tube. The lower end of thel oil-supply tube N is screwed into the stem B of the lubri cator, and communicates with an independent passage, a, formed therein.

O is an oil-regulating valve, which is ar ranged to fit the conical seat c formed in the passage u, and by means of which the quantity of oil fed from the oil-tube can be regulated.

To the under side of stem B is secured a glass or translucent cylinder, l', the upper end seating against a packing-ring, p. Surroundingthe glasscylinder l is an opelrwork shield, Q, the upper end of which is screw-threaded 'and constructed to be screwed into the screwthreaded nipple or socket q, formed on the stem B.

To the lower end of the shield Q is attached a cup-shaped nut, l, within which is received the lower end of the glass cylinder or tube l. Nut R is provided with a waste-cock, lt', for the purpose of draining the water from the glass cylinder when desired.

S is an inverted siphon-tubc, the upper end being secured to the stem B ofthe lubricator, and the lower end being upturned at .s to direct the llow of the oil upward. The glass cylinder P communicates with the oil-passage 1) in the stem B by the port s.

Having fully described the construction of my improved lubricator, I will now proceed to explain its operation.

The oil-reservoir is first lled with oil or any suitable lubricant. The stopper attached to the top of the oil-rcservoir is then screwed down a snicient distance to open the checkvalve in the upper end of the steam-inlet pipe and allow steam to tiow from the steam-pipe A, through the steam-passage t, into the steampipe in the oil-reservoir. As the steam issues from the upper end of the steam-pipe into the oil-reservoir the steam is condensed, and by reason of its superior gravity the condensewater settles to the bottom of the oil-reservoir, thereby displacing an equal quantity ot' the oil therein contained. This operation raises the oil in the reservoir, and causes it to enter and lill the oil-feedin g tube in the oil-reservoir.

Steam also enters the glass cylinder l through passage D and port s', and condcnses and lls said tube or cylinder with Water. By opening the oil-regulating valve oil descends from the oil-tube inthe reservoir,tlows through the oil-passage in the stem B, past the valve, and into the inverted siphontube in the glass cylinder.

As the column ot' oil is equal to the distance from the top of the oil-feeding tube in the oilreservoir to the lower end of the inverted tube in the glass cylinder, the weight ot' oil in said column is greater than the column of water in the glass cylinder,and hence the oil is expelled from the lower end of the Siphon-tube, and is tloated to the top of the glass cylinder, and passes into the steam-pipe through port s and passage l).

The amount ot' oil passing from the lubricator can be readily ascertained by inspecting the glass cylinder P, as drops of oil are continually ascending therein ontheir passage to the point to be lubricated. The quantity of oil in the oil-reservoir can be readily ascertained from the glass indicating-tube connected therewith, the oil standing at the same height therein that it does in the oil-reservoir.

From the foregoing it will be observed that my improvement is a radical departure from all other lubricators heretofore produced, in that the oil is fed to the point to be lubricated by the superior gravity ot' a column ot' oil over a column of condense-water, through whichthe oil is passed, and by means of which the extent of feed is readily ascertained.

It is evident that many slight changes in the construction and relative arrangement ot' parts may be devised for accomplishing the same result without departing from the spirit of my invention, and hence I do not limit myself to the exact construction shown and described; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A lubricator consisting, essentially, in the combination, with an oil-reservoir provided with a steam-pipe which conveys steam into the upper end of said reservoir and an oil-pipe, the inlet-opening of which is below the outlet ot' the steam-pipe, whereby a condensing-chamber is formed in the upper end of the oil-reservoir, of a translucent cylinder located below the oil-reservoir, and provided with an inverted Siphon-pipe, which connects with the oil-pipe in the oil-reservoir, whereby a column of oil is formed to overcome the gravity ofthe column ot' water in the glass cylinder, substan tiall y as set forth.

2. In a lubrieator, the combination, with an oil-reservoir provided with a steam-pipe which conveys steam into the upper end of said reservoir and an oil-pipe, the inlet-opening of which is below the outlet-opening of the steampipe, whereby a condensing-chamber is formed in the upper end of the oil-reservoir, a translucent cylinder located below the oil-reservoir, and provided with an inverted Siphon-pipe, of an oil-supply-regulating valve, arranged and adapted to govern the low of oil from the oilppe in the reservoir to the siphon deliveryof a translucent cylinder located below the oilreservoir, and provided with an inverted siphon-pipe and a valve for opening'or closing communication between the oil-pipe in the reservoir and the Siphon-pipe in the glass or translucent cylinder, substantially as set forth.

5. The combination, with the stem of a 1ubricator having` independent steam-passages therein, an oil-reservoir attached to the upper side of said stem, and a tube for supplying steam to the upper end of saidreservoir, of a glass cylinder connected with the'lower side of the stem and an oil-passage provided with a valve, said passage extending from the upper portion of the oil-reservoir to the lower portion of said glass cylinder, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 20th day of January, 1879. 4
