TELEPHONE CONSTRUCTION.
Application filed April 27, 1922. Serial No. 556,856.
My invention relates, to instruments for recording or reproducing sound waves and more particularly to such instruments as cmbody vibratory dia-phragms.
One object of my invention is to provide a mechanical connection between a vibratory diaphragm and a connecting link adapted to transmit vibratory. motion, thereto which shall be simple in design and construction and relatively inexpensive to manufacture.
A further .objectofimyi invention is to provide apparatus of the class described which shall be adapted for quantity production methods of manufacture, wherein slight improvements, though resulting in only a very small reduction in the total cost of the finished article, in the aggregate, involve very appreciable sums of money.
Another object of my invention is to construct a diaphragm of such material as will admit of the translation of sound waves into correspondingly modulated electrical energy, and vice versa, without impairing the quality, tone and quantity of the sound waves.
Heretofore, the various mechanical connectors designed for operatively associating the diaphragm and the vibratory link have, to a large extent, proved unsatisfactory, inasmuch as there is a tendency for such connectors to work loose during operation and hence to cause rattling.
A further disadvantage of certain prior-' art connectors is that they admit of the application of force by the vibratory link in one direction only. 11 the use of a metallic diaphragm, as hereinafter described, it was found desirable to apply force to the di aphrag'm in two directions.
A further disadvantage is that such connectors are relatively expensive by reason of the time and patience required in their construction and assembly in a telephone structure.
According to my invention, I provide a metallic connection between the diaphragm and the vibratory link embodying such design as to avoid the above-mentioned undesirable characteristics.
I have further discovered that, if the diaphragm is made of aluminum improved results are obtained over other forms of material heretofore employed.
With these and other objects in view, my invention further consists in the details of construction and arrangement hereinafter described and claimed and illustrated in the accompanying drawing, wherein Figure l is an exploded side elevational view of a connector embodying my inventlon;
Fig. 2 is a top plan view of the several elements embodied in the structure of Fig. 1;
Fig. 3 is a transverse sectional view of the assembled connector embodying my inven tion and associated with a vibratory diaphragm.
In the illustrated embodiment of my invention shown in the drawing, it will be observed that my connector 1 comprises a rivet member 2 of annular shape and is provided with a head portion 3 adapted to serve as one clinching head and a shank portion 4 adapted to be upset to provide a second clinching head 5, as hereinafter described. The rivet 2 is provided with a threaded perforation 6 disposed in the. axis thereof. The end of the shank portion may be slight- 1y countersunk to decrease the difficulty in forming the second clinching head 5. A washer 7 is adapted to embrace the shank 4 of the rivet 2 and serves as a bearin surface for the second clinching head 5. rod or vibratory link 8 is provided with a threaded portion 9 adapted to engage the threaded perforation 6 of the ri'vet 2.
A diaphragm 11 may be employed, which is provided with corrugations 12, arranged in concentric circles having radii (1,, (1 etc.. which are prime to one another, as disclosed in the patent to Phillips Thomas No. 1,522,- 758, dated Jan. 13, 1925, and assigned to the Westinghouse Electric & Manufacturing Company. The diaphragm 11 is preferably made of aluminum and is provided with a perforation 12 disposed at a point designed to serve as the center of vibration of the diaphragm. The perforation 13 is of such dimensions as to admit of the reception of the shank portion 4 of the connector 2 which extends beyond the lower side of the diaphragm 11, with the head 3 engaging the top side of the diaphragm.
In further assembling the parts of my invention, the washer 7 is disposed on the shank portion 4 of the diaphragm. The second clinching head 5 is now formed in any Well known manner, as by punching, thereby rigidly securing the rivet member 2 to the diaphragm 11. It will be observed that the washer 7 serves to provide a broad bearing surface between the second clinching head and the under surface of the diaphragm 11, which is a desirable construction. The rod or link 8 may now be sermred into the rivet member 2 and he securwl in position by means of a lock nut 14 which engages the end of the rod S and the top side of the rivet 2. Y
In orderto simplify the description of my invention, I have eliminated from the drawing the usual apparatus necessary to give the rod 8 a vibratory motion.
In addition to the several advantages mentioned in the/foregoing portions of the specification, it will be observed that my connector oilers still another advantage in the provision of an easily adjustable connection between the diaphragm and the actuating apparatus therefor. Qther advantages and applications of my invention will readily suggest themselves to those skilled in the art.
While I have shown only one embodiment of my invention. for the purpose of describing the same and illustrating its principles of operation, it is apparent that various modifications may be made lherein without departing from the spirit and scope of my invention. I desire. therefore, that only such limitations shall be imposed thereon as are sprcilically set 'iOl'tll in the appended claim or are demanded by the prior art.
I claim as my invention:
In con'ihination, a vibratory diaphragm for a souml-t-ranslating device and a member riveted thereto and provided with a threaded perforation.
In testimony 'whereof, I have hereunto subscribed my name this 18th day of April 1992.
ALEXANDER NYMAN.
