UNITED STATES PATENT OEEIOEr GEORGE W. WAITT, OE PHILADELPHIA, PENNSYLVANIA.
IMPRrOVEMENT IN CASTERS.
Specification forming part of Leiters Patent No. 145,769, dated December 23,1873; application filed April 28, 1873.
To all whom it may concern:
Be it known that I, GEORGE W. VVAITT, of Philadelphia city and county, and State of Pennsylvania, have invented certain new and useful Improvements in Casters; and I do hereby decla-re the following to be a full and exact description of the same, reference being had to the accompanying drawings forming part of this specication, in which- Figures l and 3 are sectional elevations of my invention. Fig. 2 is a top view of the channeled disk and convex roller-plate. Fig. 4 is a sectional elevation of the conical rollerplate.
Similar letters of reference in the accompa- Dying drawings denote the same parts.
This invention consists in the employment, in a caster, of conical friction-bearings held in an inclined position by a web provided with slots, said friction-rollers having an orbital and at the same time a motion of revolution on their axes, and also moving on conical surfaces on the two main portions of the caster.
In the accompanying drawings,A is the circular head, which bears the arms B, between which the wheel C is mounted. In Fig. l, this khead is represented as having a groove, F,
running aroimd its upper side, parallel with its periphery, and within the groove, and rising from the head a cone, D, from the top of which springs the vertical axis E. Resting upon this cone, and having its lower edge within the groove F, is a roller-plate, G, provided with four, more or less, radial slots, in which are placed conical friction-rollers H, which rest on the cone D, and are held in place by the plate G. I is the cap, of equal diameter with the head A, and having a top conical inside, which rests on the rollers H. Through the center of the cap I passes the axis E. The socket J,V which receives the furniture-leg, iits over a shoulder on the top of the cap I. By this arrangement the head A is allowed to rotate freely on its vertical axis, as the rollers H support the weight of the furniture.
In Fig. 3, the head A is wholly concave, the roller-plate extending downward within the same. The cone D projects from the cap I downward, and the axis .E extends from the lower end of the cone. In this arrangement there is no socket, the pintle K, springing from the top of the cap, takin g its place.
I claim as my invention- The grooved head A,provided with the cone D and conical cap I, in combination with the' slotted web G and inclined conical rollers H, as and for the purpose set forth.
