ADJUSTABLE-TELEPHONE SUPPORT AND SWITCH.
SPECFICA-'JION forming part of Letters Patent No. 286,518, dated October 9, 1883.v
Application filed March 14, 1883. (No model.) 'Y
Tok all whom t may concern:
Be it known that I, GEORGE A. WILKINs, of Philadelphia, in the State of Pennsylvania, have invented ainew and useful Improve` ment in Adjustable Telephone Supports and Switches, of which the following is a specification,
My invention consists in an improved apparatus and means for operating a switch in closing and breaking the circuit of the electric current of an open-current battery of a telephone by the adjusting movements of an adjustable telephone-support, whereby the circuit is automatically closed when the telephone is brought into position for use, and is in like manner broken when the use is suspended 5 and in the manner of constructing an adjustable telephonesupport adapted to the attachment, operation, and convenient use of a switch or switchesfor'said purpose; and in a convenient manner of attaching to a telephone-support both the receiving and transmitting apparatus; and in the special devices by which said apparatus is adjusted and retained in convenient positions. v
Figure 1 shows my adjustable telephone-support, with the telephone apparatus attached thereto not in use, the circuit being open. It is composed of a fixed hollow standard, A, which supports laterally the other portions of the apparatus, and of a movable standard, B, which stands on its own foot and is adapted to rotate thereon, held upright by standard A, and carryingtwo arms, C and D, as shown. An annular tablet (of which Fig. 4 shows a plan) is fixed at the top of the hollow standard, and by means of slot-s and adjustable stops therein, and a pin, Z, lined in said standard B, regulates and limits the rotation of the standard B. The standard B is cylindrical in form below said table, where held by the standard A, to adapt it to be rotated in its support but above said table it is square or otherwise angular, to adapt it to be iirmly graspedl by the arm O, which is tted on it so as as to slide upon it longitudinally and rotate it, as described. It may be hollow,to act as a conduit for the electrical wire.
Fig. 2 shows a longitudinal section of A,'and shows my said switch andthe means by which it is operated. These are the switch s, which is ametal pin-plate or bolt xcd into the standv ard B near its foot, and the spring fw, set and adapted to turn` said standard in the required direction to open the switch. The electrical wire with which connection is to be made is placed at the opening o, Figs. 2 and 3, within reach of said switch as it is rotated, the other connection being through the standard B. A moderate pressure on the arm C turns said standard against the action of saidspring, the switch is brought in contact with said electrical wire, and the circuit is closed. This position is retained byholding the ear of the operator against the receiver, or bythe hand,onthe removal of which the spring operates to return the standard to its first position and to throw the switch out of circuit. A stop in the table t may be used to keep the circuit closed when desired. The arm C, Fig. l,which is square, (or otherwise angular in its transverse section, carries the receiving-telephone, and an arm, D,
which is cylindrical and movable on it longitudinally, carries the'transmitter. The latter may be swung on its said carrying-arm into any desired angular position relative to the vertical plane, and into any desired position relative to the receiver, on either side thereof, by swinging its said carrying-arm on the swiveljoint k, and by sliding said arm on the arm O.' XVhennot in use, the arm D is directly under and in line with the arm O, and both arms, with all their attach ments, are carried away from the operator to their first position by the action of the spring w.
Fig. 5 is a transverse section of the holder It, by which the receiver is attached to itscarrying-arm O. It is made in two parts, one of which, w, ts and slides upon the arm C, but is cylindrical in form on its outside. The other part, yfdts around a portion of .falikea jacket, and turns thereon. These movements of said holder and its parts regulate the position of the receiver on its carrying-arm.
Fig. 3 is a plan of the base of standard A in section, showing the switch s out of circuit. A similar device for operating aswitch for the same purpose might be applied at joint k, Fig. 1, or on holder h.. l
Fig. 6 shows the arm C constructed in ytwo parts, which shut together like a telescope, for
' rence-and to provide a complete and compact f 286,5is
the purpose of regulating its length. It may be so made as to double back by means of the foldingjointf, Fig. 1.
Fig. 7 shows my said apparatus held by brackets m a,xed in a wall or like support,in lieu of the fixed hollow standard, and shows the manner of adapting the table t and spring w for use in such position. The switch s may then be conveniently placed at the table t. It shows also aportable Writing-table,P, attached to the movable standard B, so that it'can be adjusted to a standing or sitting position of the operator and folded against the wall. The purposeslof my invention are to guard against unintentionally leaving the electric circuit closed-an accident of frequent occ-urapparatus for receiving and transmitting telephonic communications, which may be used on any desk or table in ordinary and constant use, 1 Without materially encumbering it or incommoding the operator, and which will enablel him to attend to his telephone without leaving f his usual position.
I am aware that a telephone support is inuse having an arm carrying the receiver andi another the transmitter, both attached to the: same standard. I do not claim,broadly7 the use;` of two arms for such purpose on one support.
Ivcl aim as my invention- 1.. In telephonie apparatus, the rotating.
standard B and the arms C and D of a telephone-support, and the spring w, in combination, as described, with a transmitter and a receiver, and with a switch which is operated by. 3 5 the adjusting movement of said Vstandard and arms, as described, all for the purpose and in Vthe manner described.
f 2. In combination with the arm of a telcphone-support and a receiver, the receiver- 4c holder h, having the part fitted to said arm and movable longitudinally thereon, and the part `g/,tted around and movable circumferentially on said part x, as shown and described, for the purpose set forth. 45
3. In combination, as described, the stand ard B, switch s, and arm Gin a telephone-support,with a receiver andthe Wires thereof, for the purpose set forth. l
4. In combinationwitharotating standard of 5o a telephonesupport and the receiving apparatus, a switch and a spring, operating as described, the tablet, and pin Z, as described and shownand for the purpose set forth. l In Witness whereof I have signed my name to 5 5 this specification in the presence of two witnesses.
