" OF SAME PLACE.
IMPROVEMENT IN TREMOLOS FOR REED-ORGANS, &c.
Specification forming part of Letters Patent No. 117,788, dated August 8, 1871. i
To all whom it may concern:
Be it known that I, JOHN R. LOMAS, of New Haven, in the county of New Haven and State of Connecticut, have invented a new and 1m proved Tremolo for Organs and Melodeons; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure 1 represents a front view of my improved tremolo for organs, &c. Fig. 2 is an end View of the same.
Similar letters of reference indicate corresponding parts.
This invention consists in the use of a rotary prism applied to organs or melodeons in such way that the sound-waves can strike it at diiierent angles, to be reflected in different directions and thus produce the desired tremulous effect.
A in the drawing represents a body having the form of a triangular prism. If preferred, however, a quadrangular or rhombic prism may be used. It is made of thin wood or other light material, and preferably hollow, so that it can be revolved with little power. Its ends have projectin g pins a a, which are hung in a stationary frame, B. One of the pins (0 is provided with a crank or cam, b,whereby it is connected with the shaft C of the wind-wheel, which,when revolved, will impart rotary motion to the prism. The wind-wheel is arranged and moved-in the ordinary or suitable manner. When the sound-waves strike the revolvin prism at different angles they are reflected with greater or lesser force according to the differences of angles, 011 the same principle on which the waves of light are reflected, and thus produce the desired tremulous effect. The prism is to be placed in a position where the sound-waves can strike it direct after they leave the reeds.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The rotary prism A, applied to an organ or nielodeon as a tremolo attachment, as specified.
JOHN It. LOMAS. Witnesses H. LYNDE HARRISON, D. R. WRIGHT.
