UNITED STATES Patented July 19, 1904.

HARM C. ROSE, OF ROSEMONT, NEBRASKA.

TRANSMITTER.

SPECIFICATION forming part of Letters Patent No. 765,635, dated July 19, 1904.

Application filed .T 1115r 29, 1903.

T0 a/ZZ whom, it' may concern.-

Beit known that I, HARM C. ROSE, a citizen of the United States, residing at Rosemont, in the county of Webster and State of Nebraska, have invented new and useful Improvements in Transmitters, of which the following is a specification.

My invention relates to new and useful improvements in transmitters; and its object is to provide a contact adapted to be vibrated by sound-waves whereby a series of sounds of different volume may be accurately indicated to a deaf person, thereby producing sensations which can with practice be used to interpret the sounds producing the vibrations.

With the above and other objects in view the invention consists in providing a drum having diaphragms within it, from which project pins or other suitable contacts adapted to touch the skin of the person using the device, so that when the pins are vibrated correspond-v ing sensations are produced upon the skin.

The invention also consists in the further novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which- Figure l is a section through my improved transmitter, and Fig. 2 is an inner elevation thereof.

Referring to the figures, it will be seen that the device comprises a drum 7, divided, by means of partitions 8, into circular compartments 9. Within each of these compartments is arranged a diaphragm l0, and these diaphragms are of different sizes, and each has a pin 11 extending therefrom through an aperture l2, formed in the rear face of drum 7 Apertures 13 are formed in the front faces of the drum and in alinement with the diaphragms, and these apertures are of different sizes, according to the diaphragms adjacent thereto. The series of apertures 13 are inclosed by a frusto-conical flange 14.. By em- Serial No. 167,410. (No model.)

ploying the device herein described the diaphragms will not be vibrated unless the sound produced is sufficiently strong; otherwise only a portion of the diaphragms will be vibrated, and it will thus be seen that the volume of the sound produced will be indicated by the number of diaphragms vibrated.

In using this device the same is strapped or secured in any other suitable manner, preferably to the temple of the person using the same, and when a sound is produced adjacent the transmitter the diaphragms will be vibrated thereby and cause the needles to vibrate upon the skin. It will be obvious that the number and character of the vibrations will change according to the character of the sounds produced, and it will therefore be understood that with practice these differences in the vibrations can be distinguished and the sounds interpreted.

In the foregoing description I have shown the preferred form of my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus described the invention, what is claimed as new isl. A transmitter of the character described comprising a drum having inlets and outlets in opposite faces thereof, partitions interposed between the said faces and forming independent compartments, each having an inlet and an outlet, a diaphragm within each compartment and interposed between the inlet and outlet thereof, a contact secured in each diaphragm and projecting through the outlet, and a flange inclosing the inlets and projecting from the drum.

2. In a transmitter of the character described, the combination with a drum having compartments therein; of a diaphragm within each compartment, said diaphragms being of different diameters, and a contact extending from each diaphragm and projecting from the drum.

3. In a transmitter of the character described, the combination with a drum having compartments therein, and each compartment being provided With an inlet and an outlet; of a diaphragm Within each compartment, said diaphragms being of different diameters, vand a pin extending from each diaphragm through I0 the outlet adjacent thereto and a iange inclosing the notches.

In testimony whereof I afx my signature in presence of two Witnesses.

HARM C. ROSE. Witnesses:

JOHN C. ROSE, L. B. QUIGGLE.
