Description
UNITED STATES PATENT OFFICE.
DAVID D. STELLE, OF NEW BRUNS\VICK, NEIV JERSEY.
ACOUSTIC APPARATUS.
Specification of Letters Patent No. 27,165, dated February 14, 1860.
To all whom it may concern:
Be it known that I, Davin D. STELLE, of New Brunswick, in the county of Middlesex and State of New Jersey, have invented a new and Improved Mode of Applying Acoustic Apparatus in Churches and other Buildings and Apartments; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l, is a vertical sectional view of the pulpit and floor of a church exhibiting the application of my invention. Fig. 2, is a plan of the same.
Similar letters of reference indicate corresponding parts in the two figures.
The drawing represents the tunnel shaped receiver a, a, which collects the sound of an elliptical form at its month, which fits to an opening in the top of the pulpit B; and gradually assuming a circular form toward the bottom where it terminates in a circular throat I), from which a pipe 0, runs under the floor A, to the point cl, where it is led upward through the floor to connect with a taper flexible tube 0, at the end of which is a suitable earpiece g, to be placed in the ear of the person requiring it, to conduct the sound thereto but instead of being elliptical the mouth of the said funnel shaped receiver may be of circular, square or other form and the pipe 0, may be above the floor.
The receiver may be made of tin plate or other sheet metal or of wood either with or without a lining of metal. Bars f, of wood or metal may be arranged across the mouth of the receiver to support a book, which must not be large enough to entirely cover the receiver. The receiver may be applied in the same manner to a reading desk or table in any private apartment, with the pipe 0, above the floor when not convenient to place it below.
In applying the apparatus in a church or public building the pipe c, may have many branches as may be desired, and such branch may have as many other branches as may be necessary, with flexible tube connections e, to convey the sound to as many persons as may require them.
The tube or tubes 6, are not necessarily flexible but only so for greater convenience.
\Vhat I claim as my invention and desire to secure by Letters Patent, is,
The combination with a pulpit or reading table, of the sound receiver (a, (4,) and conducting tube substantially as and for the purpose shown and described.
DAVID D. STELLE.
\Vitnesses CHARLES M. Hnorrns, Mien. HUGHES.
