ADJUSTABLE MICROPHONE STAND Filed Feb. 23, 1932 INVENTOR ROBERT ESCHUETZ BY q ATTORNEY not as desirable as one wherein the microphone is in the front centeror directly above the artists- Patented Aug DJIJ sLE.'MI WQNES ANW. Q
I I Fa schuetzipflachson as a signorto Radio Corporation ofhmerica, a corporat ion-of Delaware 'invention relates to a new. and improved microphone stand'andmore particularly to stands of thetype'used-inradio'broadcasting.
An object of this invehtion is to simplify and f5 improve microphone stands for radio broadcasting ' system of suspending the microphoneanditsasf sociated amplifier in such manner that an artists lo -or speakers vision past the microphone is not obscured, thus enabling him to more conveniently read his music or notes. i
In radio broadcasting, when an artist plays 'able to see conveniently the music or continuity sheets while playing. Similarly, when a speaker; is seated at a table usingnotes for his speech, 'heshould be able to look past the-microphone? to these, notes.
was massive and resultedin blocking the vision 1:. music or notes Were generally placed to one side ofthe microphone. This position is awkward and music or notes. p
By means of the improved stand of. my invenso ftion I am able to obtain thisdesired position. This invention utilizes theprinciple that when two Weights are placed diametrically "opposite each other, the weights will be balanced if a correctglength is chosen for locating each particu- 35. lar weight upon an upright supporting post. For
example, in the: embodiment of this invention as will be seen from the drawing, the condenser microphone is placed at one endof a rather long radius arm. The associated amplifier, which is heavier, is placed at acompar-atively short radius in diametrical opposition to it. Thus, suitable selection of these lengths permits the separation y of microphone from the stand by any reasonable distance.

'Ihe" gener l structur'e of this-"mproved micro phone stand is best shown in Fig. 1 wherein the standard orbase'member I supports an upright v o I i post 2 which is arranged to be adjustable in height Another object of this invention is to providea V screw 4 is provided for clamping the telescoping by means of a shorter telescoping post 3. A set post 3 when a desired height is obtained. This set screw 4 is threaded in the adjustable and rotatingbushing 5, and although the heightis fixed when 'clampedfthe slot; I 9 allows for rotationior the arm. A T-shaped fitting 6 is fastened to the end of the telescoping upright post 3 and a short hollow tubular metallic member I is inserted in this fitting. At the other end of the member 1 there is fastened the microphone amplifier '8. A f set screw 9 is provided to fasten the microphone amplifier to the member I or to alter the length between the T fitting 6 and microphone amplifier, should an adjustment of length to properly bal ance the rmcrop-hone be required. The midroi phone I0 is adjustably mounted on fittings l land I8 which are retained in position by a rigid me-E tallic tube l,2 which is likewise inserted in the The metallic tube It is shown and described as rigidalthough it may in other n'nodifications be of flexible metallic tubing.
1 Fig. 2 shows the microphone amplifier 8 mounted on the short tube 1. When the correct adjustment of the length between the T fitting 6 and the, amplifier 8 is determined, it is secured by clampingthe microphoneS on the tube 1 by means of a set screw 9. Connectiontd the microphone is made by a single low capacity lead which is held in the exact center of the tubes 1 and [2 by successive layers of cotton braiding M, or any. other good insulating material. The metallic members i and I2 form the other conductor which is at ground potential.
Figs. 3 and 4 show in more detail'the microphone. it) together with its associated adjustable F fittings II and I8. Theset screw l5 controls the rotatable adjustment of the microphone; the extent of rotation being controlled by a slot l'l in, fitting II, which allows for 180 degrees of rotation of the microphone II]. A fitting I8 is fastened tothe end of the tube l2 and a pivot screw lfljoins the fittings H'to l8 in a manner to rotate the microphone [0 through more than degrees with the pivot screw 19 as a center. The microphone I0 is locked in its final position by the combined nut "and handle-16.
' In the operation of this improved adjustable 180 degrees it can be placed on either the left It will be noted as the microphone aznm Li's mounted on a post which is rotatable through or right hand side of the piano or table.
Although this invention hasabeen described as embodied in a particular form and arrangement of parts, it should be understood that -i t "is capable of embodiment in other and different forms and not limited to those shown, except as such limitations are clearly imposed by the rappended claims.
What I claim is: -1-. An adjustable microphone and amplifier stand comprising a microphone and an .ampli fier, :a base member, an adjustable upright tealescoping post and a hollow metallic supporting arm mounted on said'post at a point where the microphone and amplifier are substantially balanced.
2. An adjustable microphone and amplifier stand for use in a broadcasting studio, comprising a base member, an adjustable upright supporting post, said post having inner and outer itelescoping'tubes, a bushing at the %top of the outer tube retaining a set screw for clamping the inner tube when the desired height is obtained, a r-shaped fitting at the top of said inner tube, .a long hollow :arm secured to one side of the horizontal portion of said T fitting and a microphone secured to the other end of said arm, a short hollow arm secured to the other end of the horizontal portion of said T fitting, a microphone amplifier secured to the other end of said short arm, a single conductor located centrally within said long and short arms to electrically 0 connect the microphone and amplifier together.
