MICROPHONE DESK-STAND.
Specification of Letters Patent. Patented Sept. 21, 1909.
Application filed November 26,- 1906. Serial No. 345,059.
My invention relates to microphone deskstands of the character adapted to hold a 'telephone set, andl by the weight of the set to control the contacts in the circuit thereof for cutting the set into and out of voperative connection.
Theobject of my invention is to provide a stand which shall be sim-ple in its operation, economic in its construction, and durable and efficient as an article of`commercial use: My invention further relates to the details of construction whereby a positive movement is imparted to the switch-springs by the movement .of the supporting device, all of which will be hereinafter described and claimed, and which is illustrated in the accompanying drawing forming a part of this specification, and in which;
Figure l is an elevation partly l1n sect-ion of my device with the parts 1n the positlon upon the support; Fig. 2 is a perspective drawing of the lever-supporting mechanisn'n and Fig. 3 is a detail showing the means forV preventing the vertical operating rod from turning. I I
In carrying out ,my invention I provide the pressed metal base a through the circular opening in the top of which extends the metallic tubular portion b upon which is threaded the metallic ring c in such manner that the rin c rests upon the upper face of the pressed ase port-ion a.
Immediately below'the base portion and encircling the threaded portion of the stem b is placed a collar d, below which comes the apparatus mounting-plate c, the whole'being held in firm positionagainst the collar c by f which threads upon the lower end of the tube Z). Secured .to this apparatus mounting plate e are the terminalblocks, condenser and other devices, differing with theform of circuit with which the set is tobe used, and the lever supporting plate g shown in Fig. 2, which has mounted thereon the. contact-springs l1, and z which control the circuit of the telephone set.
The lever supporting plate g is provided] with the downwardly extending lugs j between which the two parallel .lever portions Z, placed a short distance apart, are pivoted at and have the spring-operating link m pivoted thereto at an intermediate point, this link having carried upon its lower endthe insulating roller n. y
The lever pieces Z have the pino, extended between their free ends, which is engaged by i the link p for operating the lever. This link`1` is secured at its upper end tothe supporting shaft gwhich'extends out at the top of the .i
stand and terminates invan enlarged portion o into-a slot of which the extending portion s is secured to carry the Y portions in which the set is supported.
The partition t is secured within the-tube p to form a guide for the lower end of the vertical supporting shaft 'g and also to form a seat for the spring u which by its pressure -upon the sleeve o keeps the shaft in its uppermost position when the telephone set is not supported thereon. p
` In order to prevent the shaft from turning the slotted washer w is placed aboutI the `shaft g in such manner that the flat-tened portion m shown in Fig. 3 rests against the face of the notch y, this washer being secured*^ l' to the top or cap-piece e by screws or in any other suitable manner.
It will be seen that by this construction I multiply the pressure effect of the weight of the telephone Set by the ratio of the lever arms of the lever l and thereby secure a very posit-ive movement to the contact spring z' whlch may by this arrangement be made comparatively heavy and stiff.
It will be understood that I have here shown and 4described 'my invention with relation to certain details, but that I do not wish to be unduly limited thereto, it being possible to carry out my purpose by the use of many` variations from thesedetailswit-hout departing from the spirit ,or scope of my invention. v 4 v What I claim as new and desire to secure by Letters Patent is.:
'1. A microphone desk stand having a vertically reciprocating rod, a telephone set directly supported by said rod in combination with switch-springs in the base of the stand, and mechanism' for imparting a. pressure upon such springs in excess of the pressure upon the reciprocating support and a link connecting 4said rod and' said mechanism, substantially as described.
2. A microphone desk stand having a vertically reciprocating set-'supporting rod, in combination with a link carried upon the lower end of said rod, switch-springs mounted in the base of the Stand, and'means to impart a pressure upon such springs in excess of the pressure upon the reciprocating support, substantially as described.
3. A microphone desk stand having a vertically reciprocating set-supporting rod, nin combination with switch-springs mounted in the base of the stand, a pair of links, one connected with the lower end of the reciprocating supporting rod and the other with the switch-springs, and lever-mechanism between such links, whereby pressure is imparted upon .the springs in excess of the pressure upon the reclprocating support, substantially as described. i
4. A microphone desk stand, having a vertically reciprocating .set-supporting'rod, in combmation with switch-springs in the base of the stand, a link' carried upon the lower end of the reciprocating rod, a pivoted lever having its free end connected with the lower end of said link, and a link connecting the switch-spring with an intermediate point on and a second said lever, substantially pose set forth. v
5. A'micr'ophonedesk stand having a vertically geciprocating set-supporting rod, in combination -with switch-springs in the base of the stand, a link pivoted upon the lower end of the supporting-rod, a pair of leverstrips engaged by the lower end of said link, link mounted between said lever-strips and enga ing the switch-springs, substantially as. an for lthe purpose set as and for the purv forth.
6. A microphone desk stand having a vertically reciprocating'set-supporting rod, in combination with switch-sprm'gs adapted to be actuated Aby the movement of sald supportingy rod, link and lever mechanism con- -co1nprising a hollow base,
necting the supporting rod and the springs,
whereby pressure 1s imparted to said springs in excess of the pressure upon the reciproeating supporting rod, substantially as described. i
7. A microphone desk stand having a vertically reciprocating set-supporting rod, switch springs in the base of the stand, a pivoted member for transmittingjthe motion of the supporting rod to the switch-springs, a link between said pivoted-member and the rod and'a second link between the pivoted member and the switch springs and a support for said pvotedmember detachably secured within the base of the. stand, substantially as described.
8. A microphone desk stand having a cylindrical set-supporting rod with a notch formed therein, in combination with a washer having a flattened portion engaging said notch to prevent' the supporting roc from turning, and having a slot extending from the periphery flattened portion, whereby the washer may be readily assembled to its engaging position, substantially as described. y
9. The combination with a microphone telephone set, of a supporting stand therefor a tubular standard supported by the base, a set supportinn rod extended within said tubular standard and adapted to be depressed by the weight of the microphone set, a slotted washer within the hollow portion of said standard, a portion of said slot engaging a flattened portion-of said rod to prevent the rod from rotating, and switch springs in the base adapted to be actuated by the depressionof said rod, substantially as described.
