A. W. BRUCE LOCOMOTIVE DRIVING BOX Filed Feb. 9, 1924 Patented Mar. 17, 1925,
7 UNITED STATES nooomo rrvn or new YORK, my.
DRI ING BOX.
Application filedFebruary 9, 1924. Serial No. 691,585,
To all whom it may concern:
Be it known that I, ALFRED W. Bnuon,
a citizen of th United States, and a resident of New York, in the county and State of New York, have invented a certain new and useful Improvement in Locomotive -Driving Boxes, of which improvement the following is a specification.
My invention relates to locomotive driving boxes, of the class or type having the usual top or crown, brass, and supplemental bearings inthe side walls below the crown tion.
brass, and its object is to provide improved means for securing the supplemental bear ings in place. The primary object of these auxiliary brasses is to prevent any tendency of the box lifting from the journal, due to excessive pressure of short main rods on two-cylinder engines, or to the efi'ect of main rod thrust on three-cylinder engines. In the preferred form of my invention, the auxiliary brasses are relatively narrow strips located below the centre plane of the journal, and which can be inserted in the .box after the axle is in place therein The improvement claimed is hereinafter fully set forth, In the accompanying drawings: Figure 1 is a front view, half in elevation and half in vertical section, ofa locomotive driving box embodying my invention;.'Fig. 2, a side view, half in elevation and half in vertical section, of the same; Fig. 3, a plan view, half in elevation and half in horizontal section. of the same; and, Fig.4, a vertical transverse section through a driving box illustrating a structural modifica- In the practice of-my invention, referring descriptively to the specific embodi-;
ment thereof which is herein exemplified,
I the driving box 1, is fitted, with a crown brass, 1 in the usual manner, and longitudinal grooves, 1, extend through the driving box, below the horizontal axial plane thereof. Supplemental bearings, 2, the inner faces of which are curved concentrically with the journal, are fitted 1n the upper part of said grooves. The supplemental bearings are held in place, and adjusted as they wear, by wedge bars, 6, the tops of which are upwardlyand mwardly inclined, and bear against corres ondingly inclined faces on the bottoms of t e supplemental bearings, Adjusting bolts, 4, pass through the wedge bars, 6, and the adjoining side walls of the driving box, the heads of said bolts bearing on the inner faces of the wedge bars, and their outer end portions being threaded and carrying nuts, 4, by tightening which the wedge bars are drawn in, thereby raising the supplemental bearings. The nuts, 4, are secured in place by wedge keys, 4". The usual lubricant containing cellar, 3, is supported in the driving box, beneath the journal.
In the structural modification shown in Fig 4,'the crown brass, 1, is reduced in width, and fits "on the top of the journal only, and the supplemental bearings, 29*, are increased in width, so as to fit both above and below the axial line of the journal, Wedge bars, 6", and adjusting bolts, 4, similar to those before described, act to similarly clamp the supplemental bearings in place.
The application of side supplemental bearings is of substantial advantage, in overcoming the tendency towards! lifting the box from the journal, due to excessive pressure of short main rods in two-cylinder engines, or the combined effort of main rod thrust in three-cylinder engines. It, therefore becomes desirable to provide facilities for efi'ectin the insertion, removal, and adjustment o the supplemental bearings, and my invention is of substantial advantage in the particulars of simplicity, strength,
accessibility from the under side of the driving box, facility of adjustment, and adaptability to standard existing equipment. I
I am aware that supplemental-bearings, fitted in a locomotive driving box, and adapted for adjustment against a crown brass, have been known prior to my invention, and do not therefore broadly claim said bearings and a wedge adjustment de vice therefor.
I claim as my invention and desire to se cure by Letters Patent:
1. The combination of a locomotive driving box; a crown brass therein; supplemental side bearings fitted therein, out of contactwith the crown brass; wedge. bars, having transversely inclined faces, on which said supplemental bearin rest; and trans versely extending adjusting bolts, bearing on the wedge bars, and acting to draw them ing box; a crown brass therein; supplemental bearings fitted in the side walls of the driving box, out of contact with the crown brass; horizontal wedge bars, located beneath said supplemental bearings, and supporting them on transversely inclined faces; bolts passing transversely through the wedge bars; and nuts on said bolts bearing on the driving box.
3. The combination of a locomotive driving box; a crown brass therein; supplemental bearings, located in grooves in the "driving box, below its horizontal axial plane, and out of contact with the crown brass, the bottoms of said supplemental bearings being transversely inclined; wedge bars seated in the driving'box grooves, beneath the supplemental bearings, and bearing against the inclined bottoms of the supplemental bearings; and means for drawing the wedge bars outwardly in the grooves of the driving box, against the inclined bottoms of the supplemental bearings.
