THOMAS H. POLLOOK, OF RICHMOND, VIRGINIA.

IMPROVEMENT IN REED-ORGANS.

Specification forming part of Letters Patent No. 150,256, dated April 28, 1874; application filed September '27, 1873.

To all whom it may concern 1 Be it known that I, THOMAS H. PoLLocK, of Richmond, in the county of Henrico and State of Virginia, have invented a new and useful Improvement in ReedOrgans, of which the following is a specification:

. The invention will first be fully described, and then pointed out in. the claims.

A A represent the reeds, B the reed-board, and O O the valves. These valves I arrange directly above the reeds in an organ operated by suction from below, so that the wind will have the most direct and unobstructed flow to the reeds, and, particularly, so that the pas sage from the reeds to wind-receiver will be entirely unobstructed, and the full measure of the sound will be utilized. By arranging the valves above the reeds in this way, I am enabled to increase the space in the air-passage to the reeds, which proportionately increases the tones. G represents inclined reflectors in the air-passages E, which I use below the valves for directing the air upon the free ends of the reeds as much as possible, by which more powerful tones are produced. H represents a plate or bar under the levers I, at the stands I, arranged on pivots, so as to swing down and let the levers fall, to be out of action while the other series A is in action, which it is sometimes desirable to do. Means will be used with said bar to restore the levers again whenever required. In order to throw the other set of reeds A out of action while working the reeds governed by levers I, I have a sliding stop, I), to cut off the supply of air to them. In constructing the bellows, I form an air-receiver, K, immediately under the reedboard B by a hoop, L, suspended a suitable distance from it, and to this receiver I attach a suction device, consisting of the swinging board N and flexible inclosing material 0, and 011 the under side of the'suction I arrange the feeder 1 consisting of the board Q and flexible inclosing material R. A valve, S, closed by a light spring, T, opens from the suction into the feeder, and a similar valve, U, closed by a spring, V, opens from the feeder to the atmosphere. The spring X produces the suction by forcing the board N down. The object of this arrangement is to bring the wind-receiver as near to the reeds as possible, to receive the sound directly from the reeds, and as soon as possible, by which the full power of the reeds is obtained; and the object of the valves S and T and their springs, as I arrange them, is to dispense with the bagging leather valves heretofore used, which flap against the seats when the suction begins and make considerable noise, whereas the springs which I use always close the rigid valves against a little pressure of air, which prevents noise, and they keep the valves closed and prevent them from falling, as the leather valves do. A represents the pipes which I arrange in the wind-receiver to receive the tones from the reeds before they enter the reservoir, by which I obtain new and valuable results in respect of the modifications of tones by the influence of said pipes. B represents the tremolo-fan, which I arrange in the wind-receiver at the issues of said pipes, which gives additional merit to the tremolo attachment. 0 represents the explosive swell, which consists of valves on the windreceiver, either back or top, to he suddenly opened at any time, by anysuitable action, to produce explosive sound.

I designate this improved organ The Clarion,

Having thus described my invention, I claim as new and desire to secure by Letters Pat ent 1. The combination of support H and post I with valve-lever I, as and for the purpose described.

2. The combination, with wind-receiver K, of pipes A A placed within the receiver, as

and for the purpose set forth.

3. The combination with pipes A A within the receiver, as described, of tremolo B, arranged in front thereof, as and for the purpose specified.

4. The combination of the wind-receiver K, pipes A A and explosible stop G arranged substantially as and for the purpose set forth.
