T 00% whom it may concern.-

Be it known that I, GEORGE M. WoLooTr, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Lubricators, of which the following is a specification, reference being had therein to the accompanying drawings- This invention relates to improvements in lubricators and more especially to hydrostatic lubricators especially adapted for use upon locomotives and other high pressure engines; and the objects of the invention are to provide a lubricator of this class which is simple in construction, efficient in its operation, and not liable to get out of order or become clogged, and if such a contingency does happen, may be readily taken apart for cleaning or repair.

It is also an object of the invention to provide the same with a series of sight feeds of the bullseye type which are not liable to be broken by the steam pressure and to arrange these sight feeds in a position where they are exposed to the light on all sides and where the engineer may conveniently look directly through all of them at once and determine their operation at a glance, the arrangement also being such that they are not affected by the heat from the boiler which tends to cloud the glasses.

A further object of the invention is to provide a device having the several advantages of the peculiar construction, arrangement and combination of parts all as hereinafter more fully described and shown in the accompanying drawing, in which Figure 1 is a side elevation of a device embodying the invention; Fig. 2 a central vertical section through the same; Fig. 3 a horizontal section on the lines 00-51; of Figs. 1 and 2; Fig. 4 is a detail showing in section one of the sight feeds and the connected casing of the next one below.

As shown in the drawings 1 is a suitable cylindrical body forming an oil and water chamber and 2 is a steam dome forming a condensing chamber separated from the oil chamber by a horizontal wall 3.

1 is a screw-threaded stud upon the back of the body for supporting the lubricator adjacent to the boiler front or in any other convenient position, and 5 is a steam supply pipe opening into the top of the steam dome to supply steam thereto.

A passage 6 shown in dotted lines in Fig. 2 is formed in the dividing wall 3, which passage is controlled by a needle valve 7, and a tube or pipe 8 leads from said passage downward to near the bottom of the oil chamber or reservoir to conduct the water of condensation from the upper into the bottom of said lower chamber.

Cast integral with the forward side of the body is a series of cylindrical shaped casings 9 arranged one above the other in a vertical row with their lengths extending transversely of the body in a horizontal position, and each of these casings is connected to the one below by a connecting neck portion 10 and the series is connected to the body and spaced therefrom by arms 1 1 formed integral with the body and the neck portions. Each of these cylindrical casings is bored inward from each end forming shoulders 12 against which are seated the inner ends of the solid cylindrical glasses 13 with thin copper rings 14 interposed between and the outer ends of the bores are of greater diameter than they are adjacent to the shoulders and are internally screw-threaded to receive the bushings 15 which are screwed in against a suitable packing 16 with a soft metal ring 17 interposed between the packing and the end of the bushing. Each bushing is formed with a hexagonal head by means of which it is turned in and is provided with an inwardly projecting shoulder 18 to engage a shoulder formed by a reduced outer end 19 on the glass which projects outward in the opening in the bushing, the edge of which opening is rounded off so as not to obstruct the view through the glasses.

The neck portions 10 connecting the cylindrical casings of the bullseye sight feeds, are bored vertically through from end to end of the series and the outer ends of this bore 20 are closed by screw plugs 21 and the communication through this bore between the easings is closed off by screw plugs 22 in the neck portions midway between the casings or sights. Leading from the bore 20 in the neck portions directly above each plug and inward through each of the arms 11 is a small oil inlet passage 23 into the inner ends of which passages within the reservoir are secured tubes 24 extending upwardly in the body or reservoir to near the upper end or wall 3, and screwed into internally screwthreaded bosses projecting outward from the neck portions, and extending across said bore into the ends of said oil passages are the nee- IIO a continuation of said passage formed in an inwardly projecting rib 28 on the side of the body and across the upper end of said body through a portion of said. passage formed in a bridge bar 29 to a discharge arm 30 screwed into a socket provided therefor at the back side of the body, which. arm is connected by a tallow pipe (not shown) in the usual manner with the righthand cylinder of the locomotive. The next nipple or that of the middle sight feed of the series discharges upward. and through a passage 31 extending inward through the arm 11, upward through a rib in the body similar to the rib 28 and thence across the upper end of the body through a bridge bar 32 near the opposite side of the body to that near which the other bridge bar extends, to a discharge arm similar to the arm 30, which arm is connected to the left cylinder of the locomotive in the same manner as the other arm. The nipple of the upper sight feed discharges into a passage 33 extending inward through the arm 11 and across the body through the bridge bar 32 to its discharge arm 30 which is connected to the air pump.

In each neck portion 10 is formed a duct or assage 34 opening into the interior of each bullseye at one side of its nipple and extending downward and outward through the side of the neck where it is closed by a valve stem 35 having a square head by means of which it may be turned in or out and open the passage to permit the contents of the bullseye to be blown out to clean the same.

Pressure equalizing tubes 36 are rovided within the'condensing chamber anc extend vertically upward therein with their upper open ends near the top of said chamber, their lower ends being secured within holes 37 in the dividing wall between said chamber and the reservoir, which holes open into the oil assages 27, 31 and 33 as indicated in dotted ines in Figs. 2 and 3. These tubes are thus inclosed within the chamber and connect the upper part of the condensing chamber with the oil discharge passages in the most direct manner to conduct live steam thereto and effectually equalize the pressure. By arranging the sight feeds in a vertical row, they may all be placed at the forward side of the lubricator body where they are protected from the heat of the boiler and by arranging them in horizontally extending casings supported. at adistance from the body, they are in a position where the engineer and fireman has an unobstructed view of them and being exposed to the light at both ends their operation may be seen without difficulty.

Having thus fully described my invention what I claim is 1. In a hydrostatic lubricator, the combination with a reservoir forming the body of the lubricator, of means at the rear side of the reservoir for supporting the lubricator, and a series of sight feeds arranged in a vertical row and supported at the forward side of the reservoir and communicating with the interior thereof to receive oil therefrom.
