JOHN SHERRY, OF ROCHESTER, NEW YORK, ASSIGN OR TO STERLING LUBRI- CATOR COMPANY, OF ROCHESTER, NEW YORK, A CORPORATION OF NEW YORK.

Specification of Letters Patent.

Patented Feb. 1.9, 1907.

Application filed May 31, 1906. Serial No. 319,418.

To all whom, it may concern,.-

Be it known that I, JoHN Summer, of

' Rochester, in the county-of Monroe-and'State of New York, have invented -a certain new .and useful Sight-Feedl for Lubricators, of

which the following is a ,specific-ation.

My invention has for its object the production of a sight-feed for lubricators which is particularly simple in construction and economical in manufacture; and to this end it .consists in the novel combinations and constructions herein-after set forth and claimed.

In describing this invention reference is had to the accompanying drawings, which like characters designate corresponding parts in all the views.

Figures l and 2 are respectively front and side elevations of one construction of my sight-feed and contiguous parts. F ig. 3 is a sectional view, partly in elevation, on line A A, Fig. 1.

My'sight-feed for lubricators comprises opposing 'sect-ions 1 and 2, spaced apart, a

transparent or glass shell 3, interposed between said sec-tions, clamping means for forcing one section toward the other and for holding the sections from movement relatively to each other, and means for prevent-l ing the transparent shell from receiving the strain of t-he clamp-ing means. p

As i-llustrated, t-he sections l and 2 are respectiVely, a base and a cap, and their oppos- `ing surfaces are Aformed with sockets 4 and annular bearing-faces 5 within the sockets.

The base 1 is formed with inlet and outlet openings 6 and 7, the inlet-opening'extending through the bottom of the socket 4 eccentric to the center thereof and communi- :ea-ting with a'source of supply, as a forcefeed lubricator, (not illustrated,) and the v outlet-opening extending through the center of the bottom of the socket 4 and communi- 4eating with a part to be supplied with 4lubri- (Not shown.) Said 'outlet-opening 7 is also provided with a suitable check-valve 8 for preventing the escape of steam in case the transparent shell 4is broken. A conduitQ, communicating with the inlet-opening V6, rises from the base, and its upper end terminates below the cap 2, is downturned, and is provided with an exit arranged over the outlet-o ening 7.

' The transparent shell 3 is of less diameter than the sockets 4, and its ends extend into the sockets 4 beyond the annular bearingfaces 5. Said shell 3 is of less length than thedistance between 'the end walls of the sockets 4.

The clamping means may be of any desirable form, size, and construction, and is here shown as consisting of members or screws 10, caocting with outwardly-projecting lugs 11, formed on the sections 1 and 2, said screws being movable in the lugs 11 relatively to the sections 1 and 2.

The means for preventing the transparent shell from receiving the strain of the clamping means comprises a metallic sleeve and packings 12. The sleeve is separable from and interposed between the sections v1 and 2, is independent of the clamping means 10, and encircles the shell 3, and its ends extend into the sockets 4, cooperate, respectively, with the annular bearing-faces 5, and are formed with beveled end faces. Said sleeve is formed with windows or openings .13, spaced apart, which divide the'sleeve into collars 14, located at the ends thereof, and lengthwise members 15, spaced apart and connecting the collars. The ,packings 12 are interposed between the beveled end faces of the sleeve and the annular bearing-faces 5, and are firmly forced against the inner upright faces of the sockets 4 and the periphery of the shell 3.

A sight-feed for lubricators constructed as described may be cheaply and economically manufactured and is particularly durable in use, since no fitting of the glass shell is necessary in order to make a tight point.

What I claim is- 1. A sightefeed for lubricators comprising opposing sections spaced apart, a transparent shell interposed between said sections, clamping means for forcing one section toward the other and for holding the sections from movement relatively to each other, and means interposed between said sections for preventing the transparent shell from receiving the strain of the clamping means., the second-mentioned means being separable from the opposing sections and independent 'of the clamping means, substantially as and for the purpose described.
