NITED STATES PATENT OFFICE.
ALBERT DIGANFIELD, OF ARLINGTON, VERMONT.
CAR-WHEEL.
SPECIFICATION forming part of Letters Patent No. 250,496, dated December 6, 1881.
Application filed October 6, 1881. (Model.)
T 0 all whom it may concern:
Be it known that I, ALBERT D. OANFIELD, ofArlington, in the county of Bennington and State of Vermont, have invented a new and useful Improvement in Gar-Wheels, of which the following is a full, clear, and exact description.
Myinventlon relates to compound car-wheels, or that class of wheels which have steel treads with a filling of less expensive material; and it has for its object, to provide a practical and durable wheel of this character, of simplified construction, and one which shall be less expensive to make than those heretofore invented.
The invention consists in the details of construction and the combination and arrangement of the segmental sections and the wedgeshaped sections, and of the manner of securing them to each other and to the hub, all as hereinafter more fully described.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure l is a front elevation of my improved car-whe l. and Fig.2 is a horizontal sectional view of the same, taken on the line as w of Fig. 1.
A represents the tim or tread 6f the wheel, which is of wrought-steel.
B represents the hub, which is cast with the flange b; and G and D represent, respectively, the segmental and wedge shaped sections, which may be of wood or cast or wrought iron or any'other suitable material.
The inner periphery or wall of the rim A of the wheel is formed with the continuous grooves a a, and the outer edges of the segmental and wedge-shaped sections are formed with corresponding circumferential tongues, which are adapted to fit in said grooves in the rim, as shown in Fig. 2.
In building up the wheel the segmental sections are first put in place in the wheel, and then the wedge-shaped sections are driven radially between their edges until the tongues of the wedge-shaped sections enter the grooves in the rim. The hub Bis then put in place in the central opening of the filling of the wheel, and the annular plate E placed upon it and secured in place by the bolts or rivets d d, which pass through the segmental and wedgeshaped sections and the flange I) of the hub.
Between the segmental sections and the wedge-shaped sections (the edges of the sechave all the advantages of a solid steel wheel.v
Although I have shown, as many wedge shaped sections as there are segmental sections, it is obvious that a less number might be used and not depart from the spirit of my invention; and it is also obvious that the number of segmental or wedge-shaped sections might be increased or diminished from the number shown and not depart from my invention.
I am aware that it is not new to fill in between hub and rim with segmental blocks, key-pieces, and an elastic band, or simply to use wedge-shaped blocks; but
What I claim as new is- 1. The combination, with a flanged hub and annular plate E, of a rim having two grooves, a a, and the sections 0 D, having each two tongues fitting said grooves, as shown and described.
2. In combination with the hub and rim of the wheel, the sections 0 and D,-having the conical boltsff placed between them in such manner as to have a drawing action upon the sections, substantially as and for the purposes set forth.
ALBERT DOW OANFIELD.
