IMPROVEMENT IN PIANO-FORTE CASES.

Specification forming part of Letters Patent No. [65,699, dated July 20, 1875; application filed April 17, 1875.

To all whom it play concern Be it known that I, HARRISON J. BAKER, of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Pianoflase, of which the following is a specification:

My invention consists of a hinged orpivoted cover for the key-board for square pianos, which is contrived to be opened independently of the top cover of the case, which. instead of coming forward to the front of the case, terminates back of the key-board and at the music-rest, so as to allow the key-board cover to be raised without raising it, and so as to expose the key-board cover and other front portions of the top of the piano to View, to relieve it of the bOX-lllG character and render it more ornamental, the keyboard cover being susceptible of ornamentation in a simple way.

Figure l is a plan view of my improved piano. Fig. 2 is a transverse section of the case, taken on the line no 00 of Fig. 1, showing the case closed and Fig. 3 is a similar section, showing the case open.

Similar letters of reference indicate correspondin g parts.

A A is the top of the case, which only extends frontward as far as the music-rest l3, and is jointed at B, so as to permit the front portion to be raised. C is the independent key-board cover, which I propose to employ for opening and closing the piano more easily than it can-be with the old construction, in which the heavy front piece is hinged to the hinged portion of the top, making a heavy lift necessary for opening and closing it, and re quiring care to avoid noise and damage; or 1 may use a flexible sliding or folding cover.

' The music-rack may swing down under the part A of the case-cover, or it may slide in and out.

JShis improvement, as before stated, is to be applied only to square or square grand pianos, and does not in any way refer to concert or parlor grand or upright pianos.

Having thus described my invention, I claim as new and desire to secure by Letters Patent As an improvement in square piano-forte cases, the hinged lid A and key-cover (J, said parts being constructed, combined, and arranged substantially as described and shown, for the purpose specified.

HARRISON J. BAKER.
