CAR-WHEEL.
SPECIFICATION forming part of Letters Patent No. 365,546, dated June 28, 1887.
Application tiled April 5A, 1887.
To all whom, it may concern.-
Be it knowntnat I, SUSAN L. SrNcLArR,a citizen of the United States, residing at Allegheny, in the county of Allegheny and State ot Pennsylvania, have invented a new and In1- proved Car-Wheel, which will be readily understood from the following description, taken in connection with the accompanying drawings, wherein- Figure 1 represents a perspective view of y my car-wheel; Fig. 2, a transverse vertical section; Fig. 3, an enlarged sect-ional view of a portion ot' the rim or tread of the wheel, having therein a recess filled with cast steel or cast-iron; Fig. 4, an enlargedl section of the wheel-rim with the cast-metal filling removed.
Among the various appendages of a railroad-ear there are probably no parts of so much The multiplicity of forms and manner of making them indicate that the manufacture is attended with much uncertainty. In order to secure a de gree of hardness enabling them to withstand rough usage and wear incident to prolonged travel on railroads, the periphery or tread of the wheels have been chilled, and to do this without producing inY other portions of the wheel an unequal shrinkage and consequent strain is a difficulty not entirely overcome.
The means employed by my father, and set forth in Letters Patent ofthe United States No. 7 2,405, December 17, 1867 describes a method of producing car-wheels whereby the shrinkage and strain were in a great measure avoided. His invention consisted in the production of a car-wheel provided with a number of radial recesses77 in its periphery or tread, whereby a shrinkage or contraction thereofcould takev place without seriously affecting other parts of the wheel, and these recesses he proposed to iill with pieces of steel or other hard metal.
Letters Patent of the United States No. 315,080, April 7, 1S85,were also granted to me for a method of filling recesses formedin the tread of car-wheels.
vMy present invention consissof a car-wheel `as a new article of manufacture. The wheel A may be of any desirable size, shape, and Weight, molded and cast in any suitable man- Serial No. 233,814. (No model.)
and in the sides and bottom of each recess. d
are small pockets or cavities g, that may be of any desirable shape. The several recesses and cavities therein are filled by pouring molten steel or cast-iron therein after any manner known to the trade or art, whereby the segments of the periphery or tread b and flange c are united and given a complete unbroken contour `by a lling, h, made even and smooth by any suitable process to lit the wheel for use.
The wheel A may be of that sort having'its web formed of a single plate extending outward from its central hub to its rim; but I prefer to form the wheel Awith a web consisting of double walls c k, which may either be plaiuor corrugated or sinuous, as a means of bracing the rim of the wheel in connection with its central hub.
I claim- 1. As a new article of manufacture, a carwheel provided with a chilled or hardened periphery or tread having one or more transverse grooves or` recesses filled and closed with metal cast therein.
2. A car-wheel provided'with a chilled or hardened periphery or tread having one or more transverse grooves or recesses therein filled and closed with metal cast in the-same and' made to conform to the contour'of the tread.
3. A car-wheel provided with one or more transverse grooves or recesses in its rim or tread and pockets or cavities in said recesses.
r 4.' A car-wheel provided with a doublewalled web and one or more transverse grooves or recesses in its periphery or tread lled with metal cast in the same.
