ORGAN PIPE. APPLICATION FILED JUNE 23. ms.

and, fpw/k I TTORNEY UNITED STATES CHARLES S. IIOSH, OF NEW YORK, N. Y.

ORGAN-PIPE.

Application filed June 23, 1916.

To all whom it may concern Be it known that I, CHARLES S. LosH, being a citizen of the United States, and resident of New York city, in the county of Kings and State of New York, have invented certain new and useful Improvements in Organ-Pipes, of which the following is a specification. 7

My invention relates to organ pipes and the object of my invention is to provide a pipe of this character with a device that will operate to produce a musical note having a reed quality of tone.

Referring to the drawings which form a part of this specification.

Figure 1 is a view of a portion of an organ pipe made of wood with my device made as an integral part of the pipe.

Fig. 2 is a cross sectional view of a portion of the same pipe taken on a line through the middle of the device.

Fig. 3 is a view illustrating a form in which the device is removable from the pipe and may be independently manufactured.

Fig. 4 is a view disclosing a form in which the membrane of the device may be placed under tension or adjusted to obtain more perfect operation.

Fig. 5 is a vertical sectional view through the middle of the pipe shown in Fig. 41.

In all the drawings similar reference characters indicate similar elements.

A indicates an organ pipe which is here shown as made of wood but which may be made of any suitable material.

B indicates a flexible membrane which may be made of mica, celluloid, paper or any other suitable material, but preferably of a material that is affected as little as possible by heat or moisture and provided with a smooth hard surface.

In its simplest form my invention comprises the pipe having a number of small perforations in one of its walls as illustrated in Fig. 1. at wa-c, etc., and the membrane 13 held to the pipe by glue as indicated by the darkened area A, the edge or border of the membrane only being held so that the pulsations of the air in the pipe will cause the membrane to vibrate and strike the surface of the pipe and thereby cause a sound resembling the vibration of a reed when the Specification of Letters Patent.

Patented May 3, 1921.

Serial No. 105,416.

organ pipe is set in action by vibrating the an therein.

The construction shown in Fig. 3 is made as an lndependent article and is shown as made in circular form but may be square or rectangular if preferred. A hole E is cut in the side of the pipe A and the plate C is held to the pipe by the rods D-D, which are rotatable on their axis and are provided with upturned ends cZ0Z respectively which engage the imier edges of the hole E as shown; nuts ee being used to clamp the plate to the pipe. The plate C s provided with perforations aaa, etc, instead of making them in the side of the pipe proper, the membrane B being mounted on the plate as shown.

In Figs. 4 and 5 is illustrated a form similar to that shown in F ig. 1, with the exception that the membrane is secured to the pipe at its upper end and not along its sides in order that the membrane B may be placed under tension. A cross piece F is cemented to the membrane at its lower end and provided with vertically extending slots ;f through which screws ff pass and enter the pipe A so that the membrane may be held in its adjusted position. This feature has been found to be of value.

A plurality of these membranes may be mounted on a pipe if a greater degree of reed effect is-desired than one will give and although I have not shown a pipe so fitted, a plurality of membranes may be used without departing from the scope and spirit of the appended claims. In fact, a better effect may be had with many small membranes than with one membrane of larger area.

Having thus described my invention I claim as new,

1. An organ pipe having perforations in one of its sides and a membrane overlying said perforations and adapted to be vibrated by the pulsations of air within said pipe against the perforated surface of the pipe.

2. An organ pipe having an opening in one of its sides, a perforated plate covering said opening and a membrane overlying said perforations and adapted to be vibrated by pulsations of air set upin said pipe against said perforated plate.

3. An organ pipe having one if its sides provided With a number of small perforations and a membrane overlying said perforations and in close proximity to the sur- 5 face of the pipe and held thereto in such manner as to vibrate in contact therewith When the pipe is sounded.

Signed at New York city, borough of Brooklyn, in the county of Kings and State of New York this 14th day of June, A. D. 10 1916.
