RAILWAY-AXLE JOURNAL-BEARING.
fiPECIFICAIION forming part of Letters Patent No. 352,876, dated November 16, 1886.
Application filed August 21, 1886. Serial No. 211,520. (No model.)
To all whom it may concern:
Be it known that I, J AOOB KRITOH, of Cleve- -land, in the county of Guyahoga and State of Ohio, have invented a certain new and Improved Railway-Car Journal Box or Bearing, (technically known as brasses,) the nature of which consists ofa box having its journalbearing surface composed of a compound or amalgam of metals suitable for said purpose, and the back or top thereof formed of castiron or its eqnivalent,in contact therewith by the force of adhesion, the'said journal-bearing great pressure, strain, and thrust to which they are more or less subjected,they often crack or break to such a degree as to render them not only unfit for use, but also dangerous and resultant in serious accidents.
It is the purpose of this improvement to make the journaLbearings (or brasses) with a re-enforeed backing or top of cast-iron or its equivalent, to prevent. this destruction of the bearings and its results before mentioned.
Figure l is a perspective view of a railwaycar-axle journaL-bearing. Fig. 2'is a transverse section, and Fig. 3 is alongitudinal vertical section.
The drawings represent a special form of a journal-bearing. The improvement is, however, applicable to other forms of axle-bearings without departing from the nature of said invention.
In the drawings, A, Fig. 1, represents the journal-bearing as an entirety, B being the bearing-surface for the axle,and made of a compound or amalgam of metals suitable for the purpose designed, preferably composed of tin, one part, copper seven parts, and one-sixtyfourth part of phosphorus,which are combined by melting together,and form that part of the bearing indicated at 0 below the line D. The part above the line D or top EG is of cast-iron or its equivalent. At the end is a segmental shoulder, F. Above and back of the collar is a flange, G, Figs. 1 and 2. The sides at HH are shaped for adaptation to a certain construction of housing or pedestals of the cars, which sides may be changed according to the nature of the case. The purpose of shaping the sides H H and flange G as shown is for adapting and holding the bearing in the housing and in The segmental shoulder relation to the axle. F is to prevent the bearing of the collar, by the lateral force'of the axle, from cutting into the face B'of the journal-bearing.
The ordinary axle journal bearings -(or brasses) become cracked, broken, or split usually in the radii of its center and longitudinally, owing to the vertical and longitudinal strain and thrust of the train. At times the bearing spreads away from the journal in the line a a, Fig. 2, so that only about the upper part, ate 0, will be upon the axle-journal. In this way the bearing is either soon worn through, split, or cracked in two, and the journal cut thereby. This is especially the case in first using new bearings, which are so liable to become a hot box. In this condition the result is that the bearing will more readily spread from the journal, leaving only a portion of the bearing for the journal, which is soon cut through or broken. By re-enforcing the bearing (or brass) by a backing of cast-iron this spreading of the bearing is effectually prevented, as the re-enforcing metal E is of such rigid tenacious character as to resist the more pliable and yielding nature of the compound metal part '0 of the bearing.
The two physical conditions of the metallic parts 0 and E are such that while theformer is susceptible .of more or less pliable extension and abrasion in its relation to the axle-journal the cast-iron backing, conversely to this, resists tensile strain in all directions inits adhesion tothe section or part 0, also resistant to the crushing-weight.
When a new bearing is used on a worn axlejournal, it is advisable to line the face of the bearing with Babbitt metal I, Figs. 2 and 3, for
2. A jou rnal box or brass consisting of a brass 1 5 0r bronze base having a journal-receiving recess therein and a re-enforce backing of castiron upon the base, the Wholeofsaid i e-enforce being above the journal-recess of the base and cohesively connected thereto upon substan- 2o tially a straight line, as and for the purpose set forth.
In testimony whereof I affix my signature in presence of two witnesses.
