PIANO ATTACHMENT;

Application filed December 13, 1924. Serial No. 755,743. i

To all whom it may concern:

Be it known that I, MONTFO-RD R. EULLER, a citizen of the United States, residing at Lima, in the county of Allen and State of Ohio, @have invented new and useful Improvements in Piano Attachments, of which the following is a specification.

This invention relates to piano attachments and proposes the construction of a resilient device attachable to the rear side of a piano or other massive piece of furniture, the object of which is to function as a buffer, warding the piano from contact with the walls of a room, and acting as a spacer for maintaining the position of the piano at any desired distance from said walls.

More specifically the object of the invention is to provide a resilient stop for the piano of such adaptability that it will automatically accommodate itself to changes in width of the spaces between the adjacent side and end of the piano and the respective side and end walls of the room, when the piano is pushed toward the corner of the room by movement either parallel with one of said walls or diagonally with respect to said corner.

Other objects of the invention will appear as the description of the preferred embodiment thereof proceeds.

In the drawings Figure 1 is a perspective view showing the rear corner of a piano with the device of my invention attached thereto.

Figure 2 is a plan view of the device.

Figure 3 is a front view in elevation.

Referring now in detail to the several figures, the attachment preferably comprises a strip of resilient material 1, such as metal having the ends 2 and 3 thereof flat and lying in the same plane, said ends being formed as lugs and provided with means such as the screws 4 for attaching the device to the rear side of the piano. The intermediate portion 5 of the resilient strip is preferably bent into arcuate form as shown in Figure 2 and surrounding the corner of the piano but spaced therefrom. In order to obtain the most resilient effect from the attachment, the arcuate portion is bent into a form which is three-fourths elliptic and so disposed with respect to the corner of the piano that it is unsupported throughout an angle greater than the exterior angle formed by the projection of the adjacent side and end of the piano.

The attachment is shown in Figure 2 in contact respectively with the side wall 6 and endwall 7 of a room, thus the arcuate portion preserves the distance of the piano from said walls by preventing creeping of the same toward said walls under the influence of repeated vibrations of the instrument, and the distance from said walls may be changed by pushing the piano either toward the side walls or end wall, or diagonally toward the corner of the room, the resilient portion of the attachment automatically changing its curvature to suit the altered conditions. On account of the unsupported nature of the resilient portion through an are greater than that subtending the exterior angle formed by producing the adjacent side and end of the piano, the stress upon the attachment at either of the points of contact with the walls of the room is distributed over the entire resilient portion, the latter changing its shape throughout in yielding to said stress. This prevents permanent bending, or breaking of the attachment under the exigencies of use and also permits of a compensated flexible pressure between the piano and the walls of the room regardless of the direction in which the piano is moved toward said walls.

To prevent marring of the base-board or walls it is preferable to line the outside of the resilient portion with felt or other suitable padding 8.

While it may be desirable in the case of pianos or other massive articles of furniture which are used in public places and he 1 quently moved about, to provide a pair of my improved attachments, one for each of the rear corners thereof, yet in the home it may be sufficient to provide but one, attaching it to that corner of the piano which stands adjacent the corner of the room. It is not necessary, however, for a piano to be set in a corner in order to obtain the benefits arising from the use of my improved device for if the piano is merely pushed in proximity to one of the walls of the room a greater resiliency of action and a more perfect distribution of the stresses incident to the pressure of the attachment against the wall is obtained than in any previously known construction.

Wherefore, it is my intention to cover by the appended claims, not only the specific form of the invention disclosed and described, but'any modified forms of the same WhlCh may be reasonably included Within the scope of said claims.

Having described my invention what I claim as new and desire .to secure by Letters Patent, is

1. An attachment for pianos comprising end lugs adapted to be secured to a side of the piano, and a resilient intermediate portion spaced from said piano and surrounding a corner thereof. '2. An attachment for pianos comprising end lugs lying in a common plane, and a resilient intermediate portion adapted to be spaced from said piano and to surround a corner thereof.

An attachment for pianos comprising end lugs adapted to be secured to one side of the piano, and a resilient intermediate both sides of the subtended exterior angle formed by producing the adjacent side and end of the piano.

4. An attachment for pianos comprising end lugs lying'in a common plane, and a resilient intermediate portion spaced from said company and having an unsupported arcuate part extending beyond both sides of the subtended exterior angle formed by producing the adjacent side and end of the piano. j 5. An attachment for pianos comprising end lugs adapted to be secured to a sideof the piano, a resilient intermediate portion spaced from said piano and surrounding a corner thereof and a strip of padding lining the exterior of said intermediate portion.

In testimony whereof I have hereunto set my hand.

MONTFORD R. EULLER.
