IMPROVEMENT lN LUBRICATORS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be it known that I, CHARLES DunLnY AUSTIN, of No. 40 Mosley street, Newcastlc-on-Tyne, machinery and commission agent, a subject of the Queen of Great Britain, have invented or discovered new and useful Improvements inLubricators; and I, the said CHARLES DUDLEY. An'srnv, do hereby declare the nature. of the said invention, and in what manner the same is to be performed, to be particularly described and ascertainedju and by the following statement thereof, that is to say My invention relates to lubricators used for supplying oil to the frictional surfaccs'of, machinery, and consists in constructing such lubricators as hereinafter described and illustrated in the accompanying drawing, the several'figures of which represent, in vertical section, various lubricators constructed according to my invention.

In figure la is the oil-reservoir;

b is the openipg tbroughavhich the. said reservoir is filled; and j c is the stopper by which the said opening is closed;

dis the neck of the reservoir; and

c is the socket in which the said neck is fixed.

f is a stopper, through which passes a dischargetube, 9, on which is placed a tube, 71-, which is closed at its upper end, and is of such a size that it shall fit loosely on the discharge-tube 9 so as to leave a passage between the said tubes, up which the oil passes into the discharge-tube, through which it descends to the surface to be lubricated.

Figure 2 represents a modification of the above arrangement, in which modification the flow of oil is regulated by means of a sct-screw, c, which works in a female-screw in the cover of the luhricator.

The said screw is furnished with a milled head, i, and the lower end of the said screw bears upon the closed end of the outer tube It, so that, by turning the said milled head, the said closed end can be depressed and moved nearer to the upper edge of the dischargetube g, in order to regulate the flow of. oil.

Figure 3 represents another modification for the same purpose.

In this modification the upper end of the tube his closed by a plug, 72-, on the lower end of which is cut a screw, k (part of which is cut away longitudinally to allow of the passage of the oil,) which screw engages in a female-screw formed in the upper part of the discharge-tube g.

The upper end of the said plug has a square head, by means of which it can be turned so as to move the closed end of the tube It nearer to or further from the upper edge of the discharge-tube, and thus regulate the flow of oil.

space between the-tubes.

A square head, k is formed on or fixed tothe tube It, by means of which head the said tube can be turned SO as to effect the adjustment of the tubes c and it relatively to each other, as hereinbefore described with" reference to the preceding modification.

Figure 14 represents parts of the lubricator represented in fig. 4, so modified as'to render them applicable to railway-axle boxes, valves, and other like machinery.

In this modification the reservoir is' dispensed with and a screwed stem, is formed on the lower part of the discharge-tube c, which stem can be screwed into the oil-passage in the axle-box,

'ihc flow of 'oil is regulated by turning the outer tube It, as described with reference to fig. 14.

Although in the arrangement shown in the drawing the reservoir is dispensed with, still I wish it'to. be understood that a reservoir may be used with this arrangemcnt.

Figure 15 represents a lubricator constructed according to my invention for lubricating steam-cylinders.

q is a steam-tight vessel, tho-upper end of which has an opening, q, for the admission of oil, which opening is closed by a screwed plug, g.

q is a screwed stem, which is screwed into the'cov'er of the cylinder or the steannpipe leading'to the said cylinder.

r r r are; three tubes, which are arranged as follows: the tube r is screwed into the lower part of the vessel q, The tube 1* is screwed or otherwise fixed in the tube r, and passes through the tube r 'rvr are holes through which the-oil enters the tube a. Y

s is a spindle-valve, which works in a recess formed in the stem g and is pressed upward by a coiled spring, s. I

t is a spindle, on the upper part of which is formed a screw, t, which works in a female-screw formed in the plug Q2 t is a milled head, by turning which in one direction the spindle t'is made to depress the valve 8, and

- thereby open the lower ends of the pipes r and r.

By turning the said head in the re'versc direction the valve is allowed to rise, and thereby cut oii'- the The reservoirs may be constructed in any ordinary manner, or they may be made as shown in figs. 12 and 13.

In this arrangement the said reservoir consists of a ring or short metal cylinder, 3, or of a frame of a square or other-shape, the ends of which are closed by glass disks or pieces, 4 4, fixed in rebates in the said ring .or frame.

The discharge-tube die or may be cast in one piece with the said ringer frame.

lheisaid reservoir is'filled through a hole at 6, which is closedfby a screwed'plng, 7

Any of the arrangements for lubricating hereinbefore described may be fitted to the reservoirs above described.

Having now described the nature of my invention, and the manner in which the same is to be performed, 1 wish it to be understood that Ido not limit myself to the precise details hereinbefore described and illustrated, as the same may be varied without departing from the nature of my said invention; but

I claim as my said invention-- 1. The improved lubricator hereinbefore described, and illustrated in fig. 1 of the accompanying drawing,

that is to say, a lubricator in which a tube closed at,

its upper endis mounted on the discharge-tube,the outer tube being of such sizeas to leavea small space between it and the said discharge-tube, so that the oil shall ascend between the said outer tube and the said discharge-tube, and descend through the latter which the arrangement of tubes describedacts in coml bination with a flat valve worked by means ofa screwed spindle, as and for the purpose described.
