Description

Oct. 8, 1929. J. J. HENNESSY LOCOIOTIVE DRIVING BOX Patented Oct. 8, 1929 UNITED STATES JAMES J. HENNESSY, OF NEW YORK, N. Y.
LOCOMOTIVE DRIVING BOX Application filed September 1, 1922 Serial No. 585,778.
My invention relates to railroad rolling stock and comprises an improved journal box construction especially adapted for use in locomotive driving boxes.
The objects of my invention are to provide an improved bearing for locomotive journals adapted to receive the end thrusts produced by the reciprocating piston and to provide an improved lubricating system for the journal.
In the accompanying drawings which illustrate a selected embodiment of tion,-
Figure 1 is a transverse section through a locomotive driving box and journal embodying my invention.
Figure 2 is a longitudinal section taken on line 2-2 of Figure 1, with some of the parts omitted to more clearly illustrate the construction.
Figure 3 ure 1.
Figure 4c is a section on line ure 1.
One of the incidental objects of my invenmy invenis a section on line 33 of Fig- H of Figtion is to adapt the construction for application to driving boxes now in use and such a box is indicated at 1, consisting of a frame provided with flanges 2 to engage the locomotive pedestals, and recessed on its underface to receive an upper journal bearing brass 3, the depending edges 4 of which rest'upon the upwardly extending edges 5 of a lower j ournal bearing brass 6,'the latter being supported in the box by a lubricant reservoir 7. Reservoir 7 is retained in the box by bolts 8 and bolts 9.
The middle portion of brass 6 is formed with a depression 10 extending longitudinally of the journal 11 and adapted to function as a waste container. Brass 6 is also provided with vertical passages 12, the lower ends of which open into reservoir 7 and the upper ends of which open into annular recesses 13 formed in the upper brass 3 and aligned with the passages in the lower brass.
An endless flexible member 14, here shown as a chain, is positioned in each of the aligned recesses 18 and passages 12, and, when the locomotive is traveling, is rotated by the j ournal so as to continually deliver a fresh supply of lubricant from reservoir 7 to the journal. Slots 15 and holes 16 in brass 6 serve to drain surplus lubricant back to the reservoir.
The two halves of the brass are provided with suitable dowels or interengaging lugs to maintain their relative position, or, if desired, the brass may be formed from one piece. In either construction the journal opening is located eccentrically of the brass so that standard boxes may be used without special machining for the application of my invention.
In my construction the journal is surrounded by the brass and as a result of the increased bearing area, the journal is backed up at front and rear so as to better resist the lateral thrust of the connecting rod. This desirable feature is obtained without preventing the removal and replacement of one or both brasses when worn. 2
I claim:
1. In combination with a locomotive driving box and load carrying journal therefor, a pair oi? complementary arcuate brasses surrounding the journal and each engaged by the sides of the box to resist lateral thrusts on the journal by the wheel-operating connection rod, a lubricantreservoir bolow said brasses, each of said brasses extending from front to rear of the journal and being provided with passages for a lubricant conductor extending from said reservoir to the top of said journal.
2. In a locomotive driving boX, a lubricant reservoir, upper and lower semi-circular brasses lining the box and laterally supported thereby, the upper brass having a circumferential recess on its inner periphery and the lower brass having formed therein vertical. passages and a waste receiving pocket be tween said passages, and an endless chain extending through said recess and passages and beneath said pocket into said reservoir.
In a locomotive driving box, upper and lower brasses lining the box and laterally supported thereby, a lubricant reservoir below the lower brass, iassages in the sides of said lower brass spaced from each other longitudinally of the journal, corresponding re CGSSQ 0 1 the inner periphery of the upper brass, and lubricant feeding elements operating in said passages and recesses, there being a Waste receiving pocket in the upper face of said lower brass.
5 In testimony whereof I hereunto affix my signature this 24th day of August, 1922.
