ACCORDION.

Application filed June 17, 192?, Serial No. 199,489.

The invention relates toaccordions of the concert class having a piano keyboard, and the object of the invention is to provide means whereby the windchest and main portions of the accordion may be shortened without reducing the length of the keyboard, thus materially lessening the weight of the instrument, or conversely the keyboard may be lengthened without width of the'keys to be increased to facilitate fingering. The invention consists in certain novel features of construction and arrangements of 1 parts by which the above objects are attained to be hereinafter described and claimed.

The accompanying drawings form a part of this specification and show the invention as it has been carried out in practice. Figure 1 is a front elevation of the improved instrument.

. Figure 2 is a corresponding plan view with a portion of the grill removed.

Figure 3 is an end elevation of the keyboard and adjacent parts of the accordion.

Similar reference numerals indicate the same parts in all .the figures.

The main parts of the accordion, comprising the lower register keys or p1ns 5, the bellows 6 and upper windchest 7, w1th its series of reed-valves 8, the latter covered by an ornamental grille 9, a portion of which.

is shown as broken away iniFigure 2, may all be of the usual construction and proportions.

The ends 10 of the windchest 7 instead of being carried upward in line with such ends to-form the ends of the keyboard casing asusual, are flared outwardly as at 11 to extend the keyboard 12 beyond the length of the windchest 7, as clearly shown in Figures 1 and 2. v 7

This arrangement permits thewhite keys 13 to be wider than is possible in the usual form and the black keys 14 also to be correspondingly more widely spaced, 'while atfording ample room for the rods 15 which of the keys correspondingly 10 lengtheningthe body, thus permitting the join the keys to the reed-valves8 for operating the latter, thus permittingthe widening while maintaining the usual ran e.

1%16 advantages of the wide keys in fingering the instrument are apparent, and will be greatly appreciated by musicians.

e improvement requires no increase in the size of the main portions of the accordion and the slight additional weight due to the small increase in the size of the keyboard casing and wider keys is negligible. Conversely, the main body of an instrument equipped with the usual keyboard having keys of normal width, ma by this invention be reduced materially in size andweight and such instrument thus especially adopted for female and juvenile performers.

I claim 1. In an accordion having a windchest and reed valves, a keyboard having extensions, the keys of said extensions lying beyond the planes of the ends of said windchest, said extensions connected to said windchest and thereby providing room for the connection's from the extension keys to their reed valves.

2. In an accordion having a windchest and reed valves, a keyboard having extensions, means connecting the keys of the keyboard to the reed valves, said windchest flared outwardly at the ends to accommodate the extensions of the keyboard and provide room for the connections between the extension keys and their reed valves.

3. In an accordion having a windehest and redvalves, a keyboard having keys lying beyond the planes of the ends of said windchest, and means connecting said outlying portions of the keyboard to the windchest, and thereby providing room for the connections from said out-lying keys to their reed valves.

In testimony that I claim the invention above set forth, Iaffix my signature hereto.

ROBERTO PANCOTTI.
