BUSHED MANGANESE+STEEL SHEAVE AND LIKE.
Application filed September 21, 1927. Serial No.- 220,958.
The inventionrelatesmore particularly to -the production of manganese steel gears, sprockets, sheaves, pulleys and the like. Manganese steel is substantially -non m achinable and heretofore it has been the practice to provide elements of the nature indicated With separately, formed or with integrally cast machinable bushings. Both expedients are objectionable, especially that.-which provides for anchoring the bushing in the act of casting. Under such. condition. the manganese steel must be excessively heavy in the hub and hence in the balance of the casting in order to prevent cracking when shrinking 5. around the soft steel orother machinable bushing.
It is the object of my invention to obviate the disadvantages of the old practice and more particularly to eliminate excessively heavy manganese steel sections in hushed castings of the character stated.
The nature of the invention consists in the provision of an integrally cast manganese steel gear, sheave or the like wheel element having a machinable bushing locked in the bore of the hub, in the act of casting, the bushing being divided longitudinally for the purpose and with the result of contracting asthe manganese steel shrinks around it in 80 the act of casting or inthe act of heat treatment. f
The preferred embodiment of the invention is illustrated in the accompanying drawing, wherein i Figure 1 is an end view of the improved bushed wheel.
Fig. 2 is a section on line 2- 2 'of Fig.- 1.
In the drawings, numeral 5 represents a solid or integrally cast gear, sheave, or the 40 like, having spokes terminating in a hub 6, whereof the bore is formed by a bushing 7 secured to place in the act of casting the main body. The wheel body or main casting'is constructed of manganese steel or other substantially non-machinable or i diflicultly machinable steel. The bushing is constructed of soft steel or other machinable metal and is further characterized by a longitudinaldivision which provides an endwise ranging gap or space 8, to permit the bushing to contract 111 response to shrinkage of the wheel casting and, hence, t5 afford a relief to shrinkage strains. The line of division is preferably on a bias in order to obtain the maximum of contraction,if necessary, by thus providmg for relative sliding movement of the overlapping ends.
The bushing is equipped withradial proections 9 which are surrounded by metal of the wheel casting and thus positively lock 59 the bushing to place. I
Having described my invention, I claim:
1. The method of eliminating excess metal and otherwise to insure uniformity of sound metal section'in wheel shapes of manganese steel or other substantially non-machinable metal, which consists in moulding the shape around a machinable bushing having spaced longitudinal wall sections whereby it is free to contract to relieve strains incidental to shrinkage of the manganese steel.
2. A wheel "shape of substantially non-machinable metal having a machinable 'center or bushing interlocked therewith in the act of casting, said bushing having a single longitudinal line of division to form an intervemng gap whereby it constitutes a relief to shrinkage of the non-machinable metal.
3. .A Wheel shape of substantiall non-machinable metal having a machina 1e center or bushing interlocked therewith in the act of casting, said bushing having a longitudinally ranging biased line of division whereby it constitutes a relief toshrinkage of the nonmachinable metal.
4. A Wheel shape of manganese steel hav-@ ing a one-piece machinable center incorpos. rated in the act of casting, said center consisting of a tube having spaced longitudinal Walls in overlapping and underlapping rela- 90 tion to-permit appreciable separation or conversely abutting relation without disturbing the bridging relation of the walls.-
In testimony whereof I aifix my signature.
