UNITED STATES PATENT OEEIcE.,

DANIEL SOHUYLER, OF BUFFALO, NEV YORK.

IMPROVEMENT lN ORGANS, SLC.

To all 'whom it may concern.-

Be it known that I, DANIEL SCHUYLER, of the city ot' Buffalo, county ot' Erie, and State ot' New York, have invented a new and useful Action for Organs and Reed-Instruments; and I do hereby declare that the following is a full and exact description of the construction and operation ofthe same, reference being had to the accompanyingdrawings, and letters ot' reterence marked thereon, making a part of this specification.

The nature of' my invention consists in so constructing the keys that the volume ot' any desired note or notes can be increased by the movement of the key or keys, they being so constructed that one or more can be pressed longitudinally back into the key-board, so as to cause one or more extra reeds to sound in connection with the front set ot' reeds. The eXtra reeds which the back movement ot' the keys causes to sound can be tuned so as to produce the tremolo.

It also consists in a new Iarrangement of valves, whereby the loss of air around the push-down7 pins during the sounding ot' the reed is prevented.

It further consists in having a. stop 7 for throwing the key or keys back in the keyboard when the usual downward pressure is applied to the keys.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

As keys are now constructed they can have only the downward movement, they having two slots for the keypins, the'slots being only ot' suficient length to allow suoli downward movement.

I construct my key with two elongated slots, I? P', (see drawing,) so that the key can be moved longitudinally back in the key-board.

In the ordinary method the key presses directly down on the push-down pin K, which opens the valve L, and as the push-down pin must work freely, more or less air escapes around the pin. To prevent this loss of air I place the valve J over the push-down pin and hole through which pin K passes to open the valve L. When the valve L is open the valve J is closed.

For the purpose of causing` the key to move back in the key-board when only the downward pressure is applied, I use a stop, consisting of a bar, a, running the length of the key-board under the front end of the keys,

with an arm, c, for each key, the arm standing at an angle of forty-five degrees (more or less) to the under side of the key, and when the bar is turned so as to bring the arm up against the end ot' the key, as shown in the drawing, the key, when pressed down,iscaused to slide back in the key-board, the stop to be operated by any ot' the usual methods of operating stops.

rlhe key A is supported by means of screw H and roller I, resting on valve J. It (the key) is pivoted at thc back end in a recess, O. When the key is pressed down it closes valve J, which forces down push-pin K and opens valve L, allowing the wind to take et'tect on reeds M M. rlhe key, when pressed down and back, opens valve L, also closes valve D and opens valve F, thus allowing reed IV to be sounded in connection with reeds M M.

By withdrawing the back ward pressure from the key, spring S closes valve F, forcing back push-pin E and valve D and key A, thus restoring the key to its original position in the key-board. The key is kept in position laterally by means ot' key-pins Z Z in slots I? P. Valve J is hinged at Y. Valve D is hinged at X. Valve L is hinged at It. Valve Fis hinged at T. Air-chambers N and O are connected by the aperture V. Arm c ot' bar ais lowered from or raised up to the end ot' the key A by turning the bar a, which turns on the pin b, and can be operated by any ot' the usual methods of shitting stops. A roller, d, can be used in the end otthe key to prevent any friction on the end ot' the key.

I claim- 1. The longitudinal action ot' the keys, they being so constructed that any one or more of them can be pressed back in the key-board at the pleasure ot' the pertor1ner,for the purpose substantially as set forth.

2. The use ot' a stop, as shown in the drawing, or any equivalent method of causing the keys to move back in the key-board when the usual downward pressure is applied to the key7 substantially as and for the purpose set forth.

3. The use ot' valves to prevent the loss ot' air around the push-down pins when arranged substantially as herein described.
