REED-PLATE FOR ACooRDloNs.

SPECIFICATlON forming part of Letters Patent No. 437,906, dated October 7, 1890.

Application led May 28, 1890. Serial No. 353,442. (No model.)

To @ZZ whom t may concern:

Be it known that l, ERNEST FETES, of the city, county, and State of New York, a citizen of the United States, have invented certain new and useful Improvements in Reed-Plates for Acoordions, of which the following is a specication.

This invention relates to an improved reedplate for accordions, in which the reeds can be arranged in a more convenient manner, Whether they are sounded by suction or pressure, so as to vibrate to their full extent, and in which the treble-reeds can be re-enforced by employing for each reed two or more tongues, so as to strengthen the tone of the same; and the invention consists of a reed-plate for accordions which is provided at one side with raised and tapering cells that are cast integral with the plate, and of reeds which are alternately applied to the top or bottom of the cells at the tapering ends of the same, according as they are to be sounded by suction or pressure.

The invention consists, further, ot certain additional details of construction, which will be fully described hereinafter, and nally pointed out in the claims.

In the accompanying drawings,Figure l represents atop view of a reed-plate which is used for the leading reeds bywhich the melody is played. Fig. 2 is avertical transverse section on the line l l,Fig. l. Fig. 3 is aperspective view of a portion of the reed-plate, shown with the bottom upward. Fig. 4 is a perspective View of a reed-plate of the form used for bass-reeds.

Similar letters of reference indicate correspondin g parts.

A in the drawings represents my improved reed-plate for accordions. This reed-plate is provided with as many parallel openings and cells B as there are reeds to be arranged on the plate. The reeds C project at one side of the plate A and correspond in length and width to the size of the reeds. The cells B are cast integral with the reed-plate, and are made to taper from the end wall a, near one side of the plate, toward the the opposite side of the same. The reed-plate A is provided with holes l) near the tapered ends of the cells B, through which holes the fastening rivets or screws d are passed, by which the butt-ends ot the reeds are attached to the reed-plate. The reeds C are arranged iiush with the openings of the cells alternatelyat the base of one cell flush with the reed-plate and iush with the inclined edge of the adjacent cell, as shown clearly in Figs. l and 3, according as the reeds are to be sounded by suction or pressure in the usual manner. The vibrating ends of the reeds are all located in the highest parts of the cells close to the end walls of the same, and are vibrated when acted upon by the air-waves to their full extent, so as to produce a fuller and more sonorous sound than when mounted on the ordinary lead reedplates heretofore in use. Special care has to be taken that the end walls of the cells B do not extend at right angles from the reed-plate A, but at an angle such as is 'formed between the sides and base ot an isosceles triangle, while the center line of said triangle, which passes through the point or apex of the same, intersects the base of said triangle at right angles. The cells B are formed ot such a triangle, as shown clearly in Fig. 2. This peculiar triangular shape of the cell permits the full and unobstructed vibrations of the reeds,

so that they respond freely to the air-waves passing through the cells, whether the reeds are acted on by suction or pressure. By my improved arrangement ot cells the reed-plate can be so arranged thatthe reeds in the treble can be doubled and trebled by the arrangement of two or three reeds for each note in the treble, in the same manner as in a piano-forte. The treble notes are strengthend by using two or three strings for re-enforcing the sound. The arrangement is clearly shown in Fig. l, and is ot great importance, as it permits the increasing of the sound ot the treble-reeds, so as to make them correspond in volume with that of the bass-reeds. ln the reed-plates for the bass-reeds two rows of cells are used in which the end walls ot the cells abut at the middle portion to the reed-plate, while the cells taper in opposite directions toward the edges of the reed-plate, as shown clearly in Fig. 4.

The advantages of my improved reed-plate for accordions are, first, that by the same the more perfect vibration of the reeds is produced, and consequently a fuller and greater volume of sound is obtained; secondly, that IOO the reed-plates and reeds take'up less room in the accordion, as the cells project only at one side of the reed-plate, and, thirdly, they can be made much lighter in brass or other cast metal than the lead reed-plates heretofore in use.

Having thus described my invention,l claim as new and desire to secure by Letters Patent-i 1. A reed-plate for accordions provided with cells having tapering side Walls projecting at one side of the plate and end Walls extending at an angle less than a right angle from the reed-plate, said cells being cast integral with the plate, substantially as set forth.

2. A reed-plate for accordions formed of taperng cells projecting at one side of the plate, and of reeds that are attached alternately to the tapered ends of the cells at the base or top of the same, so as to vibrate freely to their full extent in the deeper ends of the cells, substantially as set forth.

A reed-plate formed of tapering cells projecting at one side of the same, the end Walls of the cells extending atan angle less than a right angle from the reed-plate, and of reeds which are attached alternately to the tapered ends of the cells at the base or top of the cells and adapted to swing freely by the free ends in the deeper ends of the cells, substantially as set forth. Y

In testimony that I claim the foregoing as my inventonl have signed my name in presence of two subscribing witnesses.
