PETER GEORGE OLSON, OF ST. PAUL, MINNESOTA.
' LUBRICATOR-GUARD.
To all whom it may concern.
Be it known that I, Pnrnn GEORGE OLSON, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Lubricator-Guard, of which the following is a s )ecification.
his invention relates to lub'ricator guards. The objects of the invention are, in a ready, practical, thoroughly feasible and effective manner, to minimize the ex ansion and contraction of the nuts holding t .e sealing gaskets of the sight tubes of a lubricat-or in place, whereby leakage will be prevented; to protect the tubes from direct contact with currents of eold'air, thereby to reduce danger of breakage, due to sudden changes in tem pcratur; to prevent the flying of glass in case of the bursting of a tube, thus to elimipate a source of danger of serious injury to the engineer or fireman that is always present in a locomotive engine cab; to permit ready inspection of the tubes when desired; to facilitate the removal and attachment of the guard relatively to the lubricator; and generally to improve and increase the efii ciency and utility of such articles.
With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists, generally stated, in a lubricator guard arranged to house a )lurality of lubricator sight tubes, and rovided' with means to permit ready attac uncnt to and detachment from the lubricator, and also to hold it positively in osition against danger of working loose rom the vibrations resulting from the running of the engine.
The invention consists further in the various novel details a construction ot a guard for lubricators, as will be hereinafter fully described and claimed.
In the accompanying drawings, forming a part of this specification, and in which like characters of reference indicate corresponding parts, Figure 1 is a view in side elevation of a four tube lubricator, showing'the guard of the present invention assembled therewith, andpartly broken away. Fig. 2 is a to plan view, the lubricator being indicated by dotted lines and the guard shown in full lines. Fig. 3 is a view similar to Fig. 2, but showing the guard assembled with a three-tube lubri cator. 1
i As shown in Figs. 1 and2, the lubricator Specification of Letters Patent. 1 Application filed April 23, 1908. Serial No. 428,837.
I embodies four sight tubes, 1, 2, 3 and 4, o
which the tubes 1 and 2 are for the cylinders, the tube 3 for the pump, and the tubc4 for the main oil reservoir 5, the latter, as usual, being the longer. As the remaining portions of the lubricator, with the exception of a cer tain part hereinafter described, have nothing to do with the present invention, further description thereof is omitted.
The guard comprises a plurality of sections, in this instance three, designated, respect1vely,,6, 7 and 8, which are pivotally connected by hinges 9, and are of a contour to conform to the general outline of the group of sight tubes and lie close thereto, thereby to permit inspection thereof, for which purpose each of the sections is providedwith a plurality of longitudinal slots 10, the sections 2 being provided with two series of slot-s in order to permit inspection of the tubes 3 and 4, the series that is opposite the tube 4 being the longer. lVhile it will generally be preferred to provide the guard sections with the inspection slots, if desired, orifices may be employed, or the sections may be made imperforate, as, owing to the facility with which the guard may be removed, and which will hereinafter be more fully discussed, the provision of sightopenings or slots is not imperative, althougi of advantage.
The ends of the section 7, as shown in Fig. 2, are curved inward toward each other, but not on the same arcs, as the curve at one end is relatively short and that at the other end relatively long. The same is true of the end sections, the curve of the section 6 being longer than that of the section 8. The obj ect of this arrangement is to adapt the guard for use in connection with a group of either four sight tubes, as shown in Figs. 1 and '2, or with a group of three, as shown in Fig. 3,
otherwise the sight openings 10 in the secprojected in opposite directions and disposed to engage with the exterior of the juxtaposed sections, whereby to exert a pressure that will operate normally to cause the end sections to close inward towards or upon the center section, and thus hold the guard assembled with the lubricator tubes. The tension of these springs will be suflicient to hold the guard in place against danger of accidental detachment, as from the vibrations of the engine when running, as above pointed out, but will not operate to present objectionable resistance to flexing or yielding when the guard is to be removed.
The upper and lower edges of the sections are beaded and reinforced by wires 14 '(one only being shown), and the beads are arranged on the inner sides of the sections and thus are in proper position to engage with the grooves 15 of the gasket locking nut-s 16 of the sight tubes. This arrangement not only operates to secure an e'fiicient coaction between the guard and the lubricator, but
also positively shields the gasket locking nuts against the direct action of cold air, or highly heated air, thus to reduce expansion and contraction of the nuts to a minimum and thereby prevent leakage of the tubes. Furthermore, the guard serves, especially when imperforate, to shield the tubes from being subjected to the action of sudden currents of cold air, thus not" only to minimize the danger of breakage to the minimum, but also further to prevent expansion and contraction.
In addition to the above, it will be seen that in the event of the breakage of one of the :sight tubes, or of more than one, the glass will be prevented from flying around the cab, and thereby danger of in ury to the engineer or fireman resulting from such an accident,
and that frequently ensues will be obviated.
It is designed that the guard of the present invention shall be made in standard sizes so that itmay readily be applied to the lubricators employed on the engines of any railway system.
I claim 1. A lubricator guard comprising a plu rality of flexibly connected members or sections, and means for holding the members or i sections in operative position relatively with rality of hingedly connected suing-pressed sections, the upper and lower e ges of which are provided with means for interlocking with the object with which they cooperate.
7. A lubricator guard comprising a plurality of hingedly connected s )ring- )ressed sections the upper and lower. edges oi which are beaded.
rality of hingedly connected s )ring- )ressed sections the upper and lower edges oi which are provided with inwardly projecting beads.-
9. A lubricator guard comprising a plurality of flexibly connected spring )ressed members, the terminals of the guard bein curved on different arcs, and the upper and lower edges of the guard being provided with inwardly-projecting beads.
10. A lubricator guard comprising an intermediate and two terminal sections, the upper and lower edges of all the sections being beaded, and the ends of the intermediate section being curved on different arcs, and the terminal sections being similarly curved.
In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
