GEORGE N. EINSELE, OF CHICAGO, ILLINOIS, ASSIGNOR TO REUBEN W. NEWTON AND HARRISON F. JONES, OF CHICAGO, ILLINOIS.
SIGHT-FEE Specification of Letters Patent.
Fon weno/irons..
Application filed March 17. 1905. Serial No. 250,672.
.Tu colt whom t may concern,.- l
Be it known that I, GEORGE N. EINSELE, a citizen of the United States of America, and a resident of Chicago, Cook county, Illinois, have invented a certain new and useful Improvement in Sight-Feeds for Lubricators, of which the following is a specification.
My invention relates to sight-feeds for lu# bricators and it relates more particularly to sight-feeds employed on locomotive-boilers and `in similar situations, inasmuch as the ordinary glass-tube sight-feeds employed in suchcases are subjected to harsher usage and are consequently more liable to be broken.
My invention contemplates a sight-feed adapted to be used as a substitute for the ordinary glass tube. Instead of being more or less frangible, however, as is the case with the ordinary glass tube, my, improved sight-feed is constructed almost wholly of metal orat least is so thoroughly reinforced with metal that all danger of its being broken is precluded or greatly reduced.
Preferably it consists of a hollow body provided at front and rear with glass walls of such size and thickness as not to be readily broken, and the top o'f the said body is provided with a boss adapted to engage the upper fitting of the lubricator, while the bottom of the body is provided with a similar boss adapted to engage the lower litting, and
with this construction the ends of the said top and bottom bosses are adapted to4 simulate the upper and lower ends of an ordinary lass tube. Inthis way .my improved sighteed is, as previously stated, of a substantially non-breakable character, but at the same time adapted to be used as a substitute for the ordinary glass tube, and it will be understood, of course, that the combination of` glass and metal reinforcing means may be varied or changed in various ways, so that the sight-feed Vas a whole will be capable of use as a substitute for the ordinary lass tube without departing from the spirit o my invention.
The nature and advantages of my invention will, however, hereinafter more fully appear. Y
In the accompanying drawings, Figure'l is anenlarged front elevation of the said sightfeed, showing its connection with the side of the lubricator. Fig. 2 is an enlarged perspective of my improved sight-feed. Fig. 3 is an enlarged vertical section of the sightfeed shown in Fig?. Fig. 4 is a section on the line 5 5 in Fig. 3. Fig. 5 is a plan of the sight-feed shown in Fig. 2.
As shown, the lubricatoi has an upper fitting C and a lower fitting D, the same coinmunicating laterally with the body of the luv bricator in the usual and well-known manner. lower ends secured to said fittings by means `of the usual adjusting or clamping devices and is applied to the said fittings in the same manner that the ordinary glass tube would be employed and adjustedinto place-at least as far asthe method of attaching the upper and lower ends of the feed is concerned. Referring to Figs. 2 to 5, inclusive, it will be seen that the said sight-feed comprises a hollow body e, having its opposite ends provided with threaded portions e', adapted to receive the threaded clamping rings or caps e2. It
`will also be seen that the said body is provided at opposite ends with the shoulders e3, these shoulders being adapted to serve as seats for the circular or disk-like glass walls e4. When the parts are assembled, the clamping rings or caps e2 screw upon the said body and bear upon the said glass members, so as to clamp the latter tightly a ainst the said. shoulders or seats. The top oig'said body is formed .with an internally-threaded socket e5, adapted to receive the threaded lower end portion of the boss or cylindrical member e, it being The sight-feed E has its upper andobserved that the upper end of said boss or cylindrical member is preferably provided with internal notches e7, adapted to receive a tool for screwing theboss or cylindrical inember into place inthe top of the said body. The lower boss or cylindrical member esis preferably made integral with the. said body and may be provided internally with a small notch or recess e, adapting it for easy insertion in the fitting D, providinvn the Ilubricator is of that type in which the tlower fitting is provided with an upwardly-promoting nozzle, from which the globules o' oil are allowed to escape and rise upwardlythrough the water in the sight-feed. Thus constructed it TOO will be seen that the said sight-feed is hollow from top to bottom, its middle portion, howeverbeing slightly enlarged to provide the chamberv between the two transparent members e4. Consequently the oil can rise through the water in the sight-feed, and as the globules pass through the chamber el they can be observed readily through one of the windows or glass walls e4, it being understood that the sight-feed will be so placed that the globules will be illuminated, either by daylight or by artificial light, as soon as they enter the chamber el". r
The method of adjusting the sight-feed into place is as follows: rIhe boss or cylindrical member e6 is unscrewed from the body. The lower end ofl the boss or cylindrical member e8 is then inserted in place in the lower fitting D. Mter this the detachable or'upper boss or cylindrical member e6 is then dropped downwardly through the upper iitting C, the cap or nut c having been iirst removed l'or this purpose. A tool canthen be appliei to the upper end of the said upper bossor cylindrical member for the purpose of screwing'it into its socket in the top of the body e. In this way and as previously stated. the upper and lower ends of the said bosses or cylindrical members are adapted to simulate the upper and lower ends of the ordinary glass tube. Consequently the sightfeed can be placed in any lubricator which is adapted to receive the ordinary glass tube or transparent sight-feed. In other words, my improved sight-feed necessitates no change whatever in the construction of the lubricator, as it is adapted to be sold and used as a substitute for theV ordinary glass tube, and at the same time, as previously stated, the sight -feed is of a non-breakable or practically non-breakable character, inasmuch as it is composed almost wholly of metal, there being only enough exposed glass to permit the globules of oil to be observed as they pass upwardly through the water.
What I claim as my inventionisl. A sight-feed for lubricators, comprising a hollow body a plurality of oppositely-arranged transparent walls, and upper and lower attaching portions, said portions being adapted to simulate the upper and lower ends of the ordinary glass tube, whereby the said sight-feed is adapted to be employed asa substitute for the said glass tube the said sight-feed having an inlet-passage at its lower end and an outlet-passage at its upper end. i
2. A sight-feed for lubricators, comprising upper and lower metal attaching portions, an intermediate portion and transparent means permitting the globules of oilfto be observed, said upper and lower portions being adapted to simulate the upper and lower ends of the ordinary glass tube, whereby the said sightfeed is adapted for use as a substitute for the' said glass tube, the said sight-feed having an inlet-passage at its lower end and an outletpassage at its upperend. l
3. A sight-feed for lubricators, comprising upper and lower metal attaching portions, an intermediate portion and transparent means for viewing the globules of oil as they pass upwardly through the sight-feed, said attaching portions being adapted for establishing the desired connection between the sightfeed and the structure of the lubricator the said sight-feed having an inlet-passage at its lover end and an outlet-passage at its upper en 4. A sight-feed for lubricators, comprising a hollow body, front and rear with detachable transparent walls, and vertically-extending metal attaching portions, said attaching nection between the sight-feed and the structure of the lubricator the said sight-feed having an inlet-passage at its lower end and an outlet-passage at its upper end.
5. A sight-feed for lubricators, comprising a hollow body, oppositely-arranged detachportions being adapted for establishing condinary glass tube, whereby the said sightfeed is adapted' for use as a substitute for the said ordinary or usual sight-feed the said sight-feed having an inlet-passage at its lower end and an outlet-passage at its upper end.
6. A sight-feed for lubricators, comprising l a metal body, front and rear detachable glass walls through which the globules of oil may be observed, a downwardly-extending integral attaching portion, and an upwardly-extending detachable attaching portion, said attaching portions being of metal and adapted to simulate the upper and lower end portions of the ordinary glass tube, whereby the lOO sight-feed is adapted tobeused as'a sub- -v stltute for the 'sald ordinary or usual sightfeed-'the said sight-feed having an inlet-passage at its lower end and an outlet-passage at its, upper end.
