This invention relates to supports and more particularly to supports for microphones and the like and has as its principal object the provision of an apparatus for this purpose which as a unitary assembly includes meansto adjustably mount the microphone and an illuminating. It is, of course, common practice to illuminate the face of a speaker or singer when the speaker or singer is using a microphone to amplify or broadcast his voice particularly when such person is located within a theater, auditorium, ball room or other public place, but heretofore such illumination has been accomplished by the use of spot lights positioned among the foot lights of the stage or at other points remote from the person.
This is objectionable in that the positions of the microphone and the person and the direction of the light beams must be predeterminedly correlated for smoothness of performance and in that an attendant is required for control and manipulation of the light sources. Moreover, considerable time is required to accomplish the arrangement and in places where considerable smoke or dust is in the atmosphere the long beams are objectionable as they are particularly noticeable and overindicate the presence of impurities in the atmosphere.
Also, such as illuminating arrangement casts objectionable shadows of the microphone and sometimes a portion of its support on the person and of the person on the background of the stage. Because of unavoidable diffusion the long beams also illuminate persons or objects to the side or the rear of the performer which may not be desirable. It is, accordingly, the primary object of my invention to provide an arrangement for supporting the microphone and illuminating the performer, in which the objectionable aspects of the conventional methods are obviated.
Another object of my invention is to provide an arrangement for the purpose described which may alternatively be used to illuminate a manuscript placed in front of the speaker or singer and to illuminate the face of the speaker or singer. A further object of my invention is to provide an assembly for the purpose described which is pleasing in appearance, practical and rugged in operation, and which may be economically manufactured and assembled.
These and other objects and advantages of my invention will become apparent from a considerr ation of the drawing and the following detailed specification wherein is disclosed specifically a preferred embodiment of my invention.
A microphone is a device that converts mechanical energy waves or sound into electrical energy waves. Speaking into a microphone excites moves a diaphragm that is coupled to a device that creates an electrical current proportional to the sound waves produced. Microphones are a part of everyday life. They are used in telephones, transmitters for commercial radio and television broadcast, amateur radio, baby monitors, tape recorders, motion pictures , and public address systems.
There are many different types of microphones—the design depending upon the application. Sound recording, radio and television, and motion picture studios use ribbon or condenser type microphones because of their high quality reproduction of sound.
The element in this mic is dated June I didn’t research the Astatic mics much so I can’t tell you the periods in time that the different models were used.
I discovered a couple of Astatic D Microphones. See more old Mics. Introduced in , the Astatic model D was popular for its high frequency response which resulted in very intelligible audio. Its high output voltage was characteristic of crystal elements and its high impedance allowed for direct grid input. The case thickness was reduced in April and smaller tags were then used and the ring holes eliminated.
In , an eagle and shield was added to the rear cover to commemorate the US Bicentennial. Other variations appeared from time to time until , when production ceased, 68 years after the first D was offered. The D is often used by CB radio hobbyists and vintage amateur radio enthusiasts as part of their operating activities. At a hamfest or flea market the seller wants to dispose of items in the most expedient way possible.
To say that it worked the last time they used it is a good use of plausibility deniability for the seller but bad for you the buyer. Ignorance is bliss… and this blissful strategy could make a fast sale. Doubtful you will get any more than this. Really, no kidding. So I have plans for both of these D microphones.

I just got my Grandparent’s old Silvertone wire recorder up and running. After going through all of the grief of recapping a cramped chassis, fabricating a new bracket for a modern phono cartridge, and resurfacing the three rubber idler wheels, I’d like to see all features completely functioning again.
That means getting the microphone to work.

The Astatic Corporation is a commercial audio products manufacturer founded in Youngstown, Ohio in In , two amateur radio operators, Creed M. Woodworth, W8AHW began experimenting with different types of microphones for their “ham” stations.

Semple demonstrated some crystal pick-ups that Brush was working with, leading Chorpening and Woodworth to found The Astatic Microphone Laboratory, Inc.
Semple was brought into the company as general manager to manufacture and market the company’s model D Crystal Microphone as well as other crystal microphones, crystal phonograph pickups and recording heads.

As early as , Fessenden had been experimenting with mechanical transmitters – high frequency alternators – as a source of a pure continuous wave carrier for voice transmissions. In Dec. By inserting a water-cooled carbon microphone into the antenna feed, Fessenden could voice modulate the alternator’s output. The system was demonstrated on December 21, Fessenden then decided to test broadcast a short voice and music program on Christmas Eve.
The broadcast consisted of violin music played by Fessenden and recitation of Bible passages. Though the program was a test, it was picked up by some shipboard radio operators around Cape Cod, Massachusetts. Fessenden repeated the broadcast program on New Year’s Eve, At the time, very little was mentioned of Fessenden’s two pioneer broadcasts and they were almost forgotten.

Like the condenser microphone, this is also a type of pressure microphone, and responds to sound pressure. Shown at left is a section view of a dynamic microphone. These microphones are known for their durability; they are less fragile than condenser microphones, and are able to take in much louder noises before they begin distorting the sound.
