SPECIFICATION forming part of Letters Patent No. 700,977, dated May 27, 1902.
Application filed April 10, 1901. Serial No. 55,175. (No model.)
T0 aZZ whom it may concern:
Be it known that I, ANDREAS OLSEN, a citizen of the United States, and a resident of Ephraim, in the county of Sanpete and State of Utah, have invented a new and useful Improvement in Supports for Pianos and other Musical Instruments, of which the following is a specification.
This invention relates to elastic supports for the legs or feet of pianos and other such musical instrumentsorgans, for example-'- as stand upon a fioor. Its object is to mellow and sweeten and generally to improve the tone of such instruments; and to this end it consists in a cushion composed of a mass of soft elastically-yielding material, as indiarubber, having a concave under surface and constituting the body of the cushion and a plate of metal imposed upon and affixed to the upper surface of said mass or body and forming a crown thereto. One of said elastic cushions is to be placed under each leg or foot of the instrument.
Figure l in the accompanying drawings is a side view of one of my said cushions with the lower part of the leg of a piano, the easter of which rests on said cushion; Figs. 2 and 3, vertical sections of two different examples of the cushion; Fig. 4, a plan.
a is the mass of soft vulcanized india-rubber forming the body and base of the elastic cushion. The mass may be of any form in its plan, but preferably circular, as shown in Fig. 4, and it may have its sides of any suit able profile; but its bottom is concave, as shown at 5 in Figs. 2 and 3.
b is the crown-plate, of metal, which may be termed a regulating-plate and which is embedded in or affixed to the upper surface.
of the mass Ct. This plate may be of different size and thickness to suit different weights of instruments. Its upper surface is preferably concave in order to so receive the caster c that the leg of the instrument and the cushion may be retained in proper relation to each other. In the examples Figs. 2 and 3 said plate Z) is represented as having a downwardly turned surrounding rim 6, which is indented into the rubber andserves to retain the plate in place thereon. The said plate may be socured to the rubber in the vulcanizing proc ess or by any suitable cement after the vulcanization of the rubber.
The elastic cushion having the body and base of moderately-soft vulcanized india-rubber has especial merit in its application to the piano, as it freely permits the quiver of the instrument resulting from the vibrations of the strings and produces a softness and mellowness of tone free from any symptom of harshness. The crown-plate Z) prevents the caster from indenting itself into the center of the rubber body. The concavity 5 of the bottom of the bottom or base gives it the character of a springy arch.
The rubber mass to is represented in Fig. 2 as loosely incased in a light metallic shell (Z, which may be of any ornamental character. In the example Fig. 3 this shell (I is omitted.
lVhat I claim as my invention is 1. A cushion for the leg or foot of a piano or other musical instrument consisting of a mass of soft elastically-yielding material havin g a concave under surface and a crown-plate of metal imposed on said mass, substantially as herein described.
2. A cushion for the support of the leg or foot of a piano or other musical instrument consisting of a mass of soft elastically-yielding material having a concave under surface and a crown-plate of metal having a concave upper surface imposed on said mass, substantially as herein described.
In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 19th day of March, 1901.
ANDREAS OLSEN.

H. I. LARSEN, J. M. HANSEN.
