RIM FOR GRAND PIANOS.

Specification of Letters Patent.

Application filed March 30, 1910.

Patented Nov. 25, 1913.

Serial No. 552,450.

To all whom it may concern Be it known that I, JULIAN T. MAYER, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Rim for Grand Pianos, of which the following is a specification.

This invention relates to the rim of a grand piano which forms the outer curved frame or body. In practice this grand rim is made of a number of veneers and bent to the proper sinuous form which is required by the shape of the frame of a grand piano. This is a very expensive operation and requires a great deal of room in the factory, and only material having a uniform grain throughout its length can be used.

The principal objects of this invention are to provide a construction in which the rim can be made in such a way that the parts thereof can be manipulated in a comparatively small space in the factory and in which the same piece will not have to be subjected to such a great degree of bending in opposite directions as has been the case heretofore; to provide a construction in which shorter pieces of wood can be employed thus reducing the expense of the material; and to provide a construction in which the rim will be ornamented by vertical lines upon its face.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings in which,

Figure 1 is a plan of the rim of a grand piano constructed in accordance with this invention, and Fig. 2 is a fragmentary elevation of a portion of the same.

When constructed according to this invention, the rim of the piano instead of being made in a single piece as heretofore, is formed of a plurality of pieces a, I), c, and d. These pieces are formed with rabbeted joints at their ends, each piece having an outer flange e forming part of the joint and overlapping a similar inner flange f on the next piece. These flanges are of substantially half the thickness of the rim at that point. Each joint also has an overlapping outer edge e by means of which the rabbeted joints can be made very strong and at the same time a handsome vertical line is caused to appear at the end of this overlapping edge giving an appearance of fine finish and strong construction to the piano body. In this way it will be seen that by dividing up the rim as has been stated, the instrument is given a richer and more attractive appearance in spite of the fact that the construction is materially cheapened, both in the cost of material and labor.

It will be understood that the parts are glued together at the rabbeted joints and that these joints can be located in various different positions. W'hen located in the places indicated in Fig. 1, two of the members of the rim, a and d, are perfectly flat and all the curve comes in the other two which are divided at a place between two curves, leaving the piece I) with a comparatively short double curve. In this way this piece can readily be manipulated to produce this curve, Without requiring any great amount of room for the heating and bending and only comparatively short pieces having the best uniform grain have to be selected, and in fact the pieces a and cl need not be especially suitable for bending at all.

WVhile I have illustrated and described only one preferred embodiment of the invention, I am aware that changes can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claim. There fore, I do not wish to be limited to all the details of construction, nor to the location being of greater thickness than the distance i my hand, in the presence of tWO subscribfrom the outer surface of the inner overing Witnesses. lapping portion to the outside of the piece from Which it projects so as to project be- JULIAN MAYER 5 yond the surface of the next piece to form Witnesses:

a vertical line at the end thereof. BELINDA HELEN POTTER,

In testimony whereof I have hereunto set THOMAS MGGONKEY.
