SHEAVE.
SPECIFICATION forming part of Letters Patent No. 398,897, dated March 5, 1889.
Application filed December 6, 18881 Serial No. 292,812. (No model)y .To n/ZZ whom.y H lll/fig conf/'H1 s lie 1t; know'n that l, YY1 lylylmtii 5. hislNGEn, a citizen ot the l'nitcd States, residing at:
j in two parts, u. ohci which d' designates that l oil the supporting-trame or permanent por- Bellevue, ("ampbell county, Kentucky, have invented new and useful .lmpriiycinents in Sheaves or Carrying-Pnllcys, oi; which the ti'olthe spokes are cast lugs d, with beveled outer lowing is a specification.
My invention relates to carrying pulleys or sheaves-such, for example, as are employed in cable railways 'for supporting the traveling cable in the tunnel-way beneath the slot. These pulleys are subjected to yery great surface-wear from the action of the cable, and at the same time are lused in relatively large numbers, which circumstances necessitate the cheapest practicable construction and every aid to durability. In orderto meet' these conditions, and also to obtain the most perfect r0- tundity and proper balance, l construct the pulley by casting in two parts, these parts bej ing formed to interlock together without bolts 1 as they come from the mold, without lathework or other special fitting. parts is the permanent frame or supporting skeleton of the pulley, while the other is the replaceable section of the periphery, the two being1 divided upon planes transverse to the axis. The action of the interlocking deyices is aided by the pull of the cable, so as to hold the parts properly together. features are also added, which will be fully described hereinafter.
Mechanism embodying my invention is illustrated in the accompanying' drawings, in which Figure l is a i'aee or side view oi' the pulley complete, showing the permanent constituent One of these Certain minor l tion, and c? the detachableportion or annulus. The part o is cast with the usual hub, b, spokes c, and constit nies the supporting-frame of the pulley. Near the outer extremities ot faces, as shown in Figs. 2 and 5, and projecting out-ward concentrically at? equal angles apart. The detachable portion or annulus d2 is east with eorrespondin recesses, e, in its inner pe'ripheral wall, each tianked at one side by a beveled surface, c', the parts being so formed and proportioned that when placed together the lugs d pass through the recesses c, and by a partial rotation of the annulus the beveled faces of the lugs bea against and interlock with the beveled surfaces e.
The relative position oi' the parts and the contour surface of the composite pulley are clearly shown in Fig. 5, wherein it willbe seen that the wear oi' the cable is wholly taken upon the removable annulus a?, which can be re newed at will with trilling expense. It will be also understood that the pulley is so placed in relation to the movement of the cable that the pull ot the latter holds the annulus to its described position against the opposing` friction of the pulley in its journalbearings. l may however provide upon each portion a perforated lug, j, which register when the parts are in position, so that a pin may be driven, through both to retain the parts in position; but this is not absolutely essential.
The pulley is cast with a hollow center, and may run upon a stud, or be provided with a permanent axle-pivot, as desired.
The particular advantages of this construction are, iirst, the cheapness over pulleys sep` arable into three or more parts; second, the economy and other advantages ot dispensing' with bolts orV separate fastening devices, and, third, by preserving the continuous circular form of parts a much more truly-circular and evenly-balanced pulley can be produced in casting than where segmentalor other forms of parts are used, owing to t-he unequal shrinkage of the metal and the displacement of patterns in the mold. A furtherincidental advantagcis that a much lighter pulley een be produeed of d given strength, all tending not only to economy in eost of pulley, but durability and eeonomy of maintenance in use.
I claim as my invention, and desire to Secure by Letters Patent of the 'United Statesml. A Composite sheeve or carrying-pulley 'for cable railways and other uses, composed of two parte, to wit, n supporting frame or hub portion and n separa-ble annnlus containing' the heit-groove or Wem-ing portion entire, the parts being formed with corresponding in terlocking` lugs :ind recesses, whereby the Same t and are held together Without bolts or other sezpztretteA fastening's, Substantially als set forth.
f2. In a composite pulley havingthe Wearing portion of its rim detachable, e permanent or hub portion provided withv concentric ings `the part a', provided Withthe hub Z1, Spoke c,
and beveled lugs d., with lthe annnlns a?, profvided with recesses e, :und beveled interlocking` surfaces e', substantially as Set forth.
In testimony whereof l have hereunto set my hand in the presence of two snliserihng witnesses.-
