H. B. BAKER DRIVING BOX EQUIPMENT 2 Shets-Sheet 2 Filed May 2'7, 1941 Patented Aug. 10, v 1943 2,326,426 naivnve BOX EQUIPMENT Homer Burton Baker, Baltimore, Md, assignor to The Balmar Corporation, Baltimore, M1, a corporation of Maryland v 'Application'May 27,1941, SerialNo. 395,333 I ,7.Claims. (c1.1o-225) This invention relates to the adjusting mechanism customarily employed in locomotive driving boxes," and is particularly concerned with the provision of improved means for substantially eliminating galling' of the moving parts and thereby minimizing wear and increasing the useful life of the equipment. A typical mechanism ofIthis kind is disclosed, in the United States Patent to Roberts No.'1,777,578 to which reference may be had if so desired for avery complete description of the manner .in which these devices function;
The adjusting'mechanism is installed at a side of the driving box between the box and the face" of the adjacent pedestal jaw, which latter, of course, is a part of the locomotive frame. The box and the pedestal are generally constructed of steel, and since there is more or less constant relative motion between all of the parts there is a tendency toward gelling and excessive wear between adjacent steel surfaces.
The present invention has for its primary object the provision of means for eliminating or at cent steel surfaces. More specifically stated, it is the object of my invention to apply an antifriction facing to at least one of two adjacent steel surfaces such, for example, as, a facing of hard bronze or other suitable bearing metal.
In applying such facings certain difficulties have been encountered, to the overcoming of which the present invention is directed. For example, attempts have been made to apply a bronze facing either by directly casting the bronze or by flow-welding it against the surface of the steel. This procedure involves a consider able concentration of heat, and when used in applying the bronze either to the floating plate or to the compensating plate of the adjusting mechanism has resulted in warping of these plates so that excessive machining has been required to true-up the parts. In addition, it has been found that this procedure tends to develop least greatly reducing the wear between adja- V a porous structure in the bronze which is highly- It is the object of my invention to overcome these difiiculties, and I accomplish my purpose in the following manner, reference being had to tension [9 at the upper end of one of the wedge v theaccompanying drawings which illustrate preferred practice Figure 1 is a partial side elevation of'a locomoe tive driving box equipped with my improved adjusting mechanism; f Figure 2 is a section on an enlarged scale taken asindicated by the line 2-2 of Figure 1;
Figure 3 is an elevation of the pedestal face of the wedge; and I i g g Figure 4 is a section taken as indicated by the line 5-4 on Figure 3."
In the drawings, the locomotive ,frame' is shown at 5, and one of the pedestal jaws for the box 6, is illustrated at 1. The usual pedestal binder 8 fits across the bottom of the jaws.
The adjusting mechanism is installed between the box 6 and the jaw land consists of a floating plate 9 and a wedge or compensating plate In. The parts 6, l and Ill are usually constructed of steel and where two steel faces come together, as between the jaw l and the wedge Hi, there is a tendency for the parts to gall or out.
In applying my invention in practice I prefer to apply a bronze facing H to the pedestal side of the wedge or compensating plate 10.
This facing is composed of a plurality of parts,
preferably two, each of which is an individual longitudinally extending plate member Il'a and face of the wedge by means of welding applied 'at the margins, including the periphery I3 and the adjacent edges between the plates. In this way I completely avoid any large concentration of heat with its coincident development of undue porosity and eliminate the troublesome warping hereinb'efore mentioned. I also provide for the formation of a lubricant passage I5 which is drilled directlythrough the weld M between the adjacent edges of the plates Ila and lib. By forming a passage through the weld a continuous channel is provided for the lubri cant without the possibility of there being an opening from this channel tothe under face of the bronze facing between it and the steel of the wedge. This lubricant passage delivers into the Z-channel It on the pedestal face of the bronze. Lubricant is delivered through the connecting passages ll and I8 which are formed in an exfianges 20. Another passage 2| connects the passage H! with the hole'l5 through the weld.
While I have shown my bronze facing as being composed of two independent bronze plates marginally welded to the steel surface of the wedge,
'yet I wish it to be understood that the facing but if necessary or desirable it can be applied to V the floating plate as well as to the facespfthe ally welded the surface thereof andto "one" another, together with a lubricant passageiilormtd through the weld between adjacent plate edges.
