IiVHVROVEilENTV IN WHEELS AND PULLEVS.
Specification forming part of Leiters Patent No. 122,456, dated January '2, 1872.
ing part of this specification, and in which- Figure l represents an inner face view of a railroad car-wheel constructed in accordance with my improvement, and Fig. 2 a transverse section ofthe same as'` fitted to its axle. Fig. 3 shows av transverse section of a pulley (in part) similarly constructed. Fig. et is a sectional view, on a larger scale, of the outer portion of the wheel represented in Figs. l and 2. y Similar letters of reference indicate corresponding parts throughout the several figures of the drawing.
My invention consists in a novel construction of wheels and pulleys by forming them or their bodies and rims in two main parts out of y elastic sheet-metal plates, struck up in suitable dies or otherwise made to form dish-shaped elastic disks, the one smaller than the other,
and so that on arranging them with their hollow sides face to face, the smaller dish-shaped disk, which constitutes the one side ofthe wheel or pulley, is caused, by a hanged construction of it, to rest concentrically lwithin and against the other or larger disk that is constructed to constitute both the" opposite side or face of the wheel or pulley and tread or rhn thereof; also, in case of a railroadcar or other like wheel, the flange thereof. And in this connection the invention further consists in such a constructionml ofthe dish-shaped disks as that the smaller disk is made selfcentering within the larger one by causing its iiange to rest upon a beveled or curved surface formed within the larger one. Wheels or pulleys constructed according to this invention may be made cheap and combine lightness with strength, and when made of steel possess a large and almost universal'elasticity.
Referring in the iirst instance to Figs. l, 2, and 4c of the accompanying drawing, A represeuts the one side or face, B the rim or tread, and G the iiange of a railroad car-wheel, all
i formed in one piece out of a sheet or plate of steel cut and pressed or struck up in a Vdie to form a hollow or dish-shaped steel disk of the shape shown in the drawing, and which may 4be done by means of a machine or press coustructed and operating substantially as described .iu Letters Patent of the United States issued to me December 1,1868. D is a smaller hollow or dish-shaped steel disk, struck up or y formed in a similar manner, and made with a flange, a, which, when said disk is iitted to its 1place within the larger disk, rests upon or against a beveled or curved surface, b, formed at the junction of the side yA with the rim B of the larger disk. This bearing of the smaller disk (which constitutes the other side ofthe car-wheel on the largerone serves to secure a concentric arrangement of the former disk within the latter. Between these dish-shaped elastic disks, at their center, may be arranged a castiron or other suitable hub, E, formed'with shoulders for the disks to rest against and projectin g at its reduced ends through the disks. The hub and elastic disks thus arranged may be secured together by bolts c, and the whole fitted to the axle F in any suitable manner. A railroad car-wheel, the body, tread, and iiange of which are all made up of but two pieces of sheet-metal disks of dish-shaped form, arranged'one within the other, as represented and described, combines not only lightness with strength and cheapness of construction, but secures an elasticity to it in various directions-as, for instance, in direction ofthe axis of the wheel, transversely thereto, and in a twisting direction crosswise of the axle. rlhis universal elasticity relieves the axle of strain on the wheel passing over irregularities in the rail-surface, and more especially as occurring at the joints of the rail sections and secures an easy Vrunning action generally to the car. By the bearing of the flan ge t of the smaller disk on the bevel b formed in the larger one the smaller disk readily returns or adjusts itself to its concentric arrangement within the larger one on any displacement of it therefrom by the tipping or skewing of the axle. For carriage and other wheels 1n which no outer iiange C is required the same is omitted in shaping or stamping the larger disk. Fig. represents a sheet-metal pulley, constructed substantially as described, of two hollow or dish-shaped elastic disks,`which are arranged one Within the other, and made the one to support the other, as hereinbetore specified With reference to the car-Wheels shown in Figs. l and 2.
It is an essential feature in this invention,
'in order to secure an independent elasticity to 2. The hollow sheet-metal elastic disk l),
formed with a ange, a, in combination with the reversely-arranged larger elastic disk of similar character, but constructed to form both the 011e side of the body and 'rim or tread of the Wheel or pulley, and formed with a beveling or curved seat, b, for the liange a of the smallery disk to bear against in the tit of the one disk Within the other, essentially as specilied.
3. A Wheel or pulley composed of steel plate or other elastic sheet metal, the parts of which, though mutually sustaining, are bound together only at or near the hub or center, and allowed to preserve, independently of each other, their natural elasticity in other parts, substantially as herein described.
