MUSICAL-INSTRUMENT INSULATOR.

SPECIFI SATION forming part of Letters Patent No. 228,962, dated June 15, 1880.

Application filed March 13, 1880. (No model.)

To all whom i may concern Be it knov n that I, CHARLES S..WEIR, of

Madeira, Ha: iilton county, Ohio, have invented certain nw and useful Improvements in Musical-Instrument Insulators, of which the following is a specification.

This is an improvement on Letters Patent No. 150,112, issued April 21, 1874, to O. Vigneron, and my invention consists in constructing the insulator therein described without slots or such other intervals.

In the annexed drawings, Figure 1 is aperspective view of one form of my insulator. Fig. 2 is a partially-sectionized elevation of another form of the device, and Fig. 3 is an axial section of a modification of the same.

Referring to Figs. 1 and 2, A represents a solid glass block of any desired shape, and B is a shallow pit or recess in the upper end of the same, which pit is designed to receive the caster of a piano or organ or other similar instrument, as indicated by dotted lines G in Figs. 2 and 3. As represented in Fig. 1, this block is a perfect cylinder; but it may be ornamented with vertical flutes or moldings, or with one or more circumferential grooves, G, as seen in Fig. 2 or the insulator may take the shape of a glass shell, D, with a base or bead, E, and be filled with any suitable cementor composition, F, as represented in Fig. 3. This composition, however, n1 nst be of such a nature as to render said shell practically solid, or it will not be able to resist the required pressure; or the device may have a conical or pyramidal or other form, as the exact shape and proportions of the insulator constitute no part of my invention; but whichever construction is adopted care must be taken to make the block sufficiently strong and solid to sustain the pressure imparted by one leg of a piano or organ or other heavy musical instrument. Furthermore, the block must be free from slots or grooves of any kind, as such defects would produce false vibrations, and thereby impair the clear tone of the piano.

Of these insulators, one is to be placed under each corner of the instrument, with the caster G seated in the pit B, care being taken to have this pit so shallow as to prevent the leg of the piano resting upon the block A, as such contact of the leg and block would defeat the object of my invention. This elevation of the piano-leg above the insulator is indicated by the dotted lines If in Figs. 2 and 3.

I am aware that it is not new to make a slotted piano-insulator of glass and provide the upper end of the same with a deep pit or cavity, in order that the leg of the instrument may rest on the top of the insulator, as such a construction is seen in the patent of Vigneron previously alluded to. the art, my claim is not designed to be construed broadly, but is expressly limited to a glass insulator free from slots and having at its upper end a shallow pit, within which rests the caster, and thereby prevents the leg of the instrument coming in contact with the solid insulator.

I claim as my invention A musical-instrument insulator consisting of a solid glass block, A, having a shallow recess or pit, B, at its upper end, constructed and adapted to receive the caster of a piano or organ, and to prevent the leg of the instrument coming in contact with said insulator, as herein described and illustrated.

In testimony of which invention I hereunto set my hand.

CHARLES S. WEIR.
