Description

Dec; 1937- J. J. SCHREIBER 2,101,271
SUBSTATI ON TELEPHONE APPARATUS Filed March 20, 1957 INVENTOR By LJJ. SCHRE/BER ATTORNEY Patented Dec. 7, 1937 UNITED sTArss PATENT QFFICE SUBSTATION TELEPHONE APPARATUS York Application March 20, 1937, Serial No. 131,979 In Belgium June 17, 1936 5 Claims.
This invention relates to telephone subsets and, more particularly, to attachments or adaptor boxes therefor.
The object of the invention is to provide an attachment which comprises a locking pushbutton, key, or the like, and is readily attachable and detachable from a standard subset in such a way that the locking key can be unlocked by the depression of the switchhook.
This object is attained by providing a flexible transmission cable connection between the subset and the locking device in the adaptor box.
Such a device is of value for adapting ordinary subsets for special purposes such as for connection to two lines with provision for holding on one line while calling on the other line.
An adaptor box according to the invention and its connection to a desk-set will be described below with reference to the accompanying drawins;
Fig. 1 of which shows the desk-set and box in side elevation with the covers partly cut away to expose the novel mechanism; a
Fig. 2 shows the method of mounting the end of the flexible connection in the desk-set on a larger scale.
The adaptor box 2 carries a push-button 3 on a vertical stem 4 journaled in a stirrup 1 within the box. The stem 4 carries a locking member 5 of inverted cone shape, and a compression spring 6 between the lower arm of stirrup 1 and the bottom of locking member 5. The stirrup 1 also carries a pivoted two armed locking lever B, 9, which is biased by a spring [6 so as to tend to rotate in a clockwise direction.
The stirrup l is mounted on a vertical support H in which is fixed one end of the outer flexible tube [2 of a Bowden wire transmission cable. This tube 12 is led out through the side of the box. Through the tube passes the transmission wire it carrying at the end inside the box 2 a plunger ill, impinging on the bottom end of the lower arm 9 of the locking lever.
When such an attachement comprising the box 2 with the Bowden wire connection is to be attached to a desk-set l, a bracket 15 is fixed to the base of the desk-set, which is perforated for the passage of the cable l2, l3. The end of the flexible tube I2 is fixed in the bracket 55 which is so positioned that a plunger l4 attached to the end of the transmission wire I3 can be operated by the switchhook assembly.
In the position shown, the microtelephone or telephone handset is off the switchhook, and the button 3 is locked in depressed position by the locking lever 8, 9. If, now, the switchhook is depressed, the plunger I4 is forced downwards causing the wire 53 to force the plunger NJ in the box 2 to the right. This movement of plunger l0 rotates locking lever B, 9 anti-clockwise against spring it so that the lever arm 8 releases the member 5 and the stem 4 and the button 3 are raised to normal position by spring 6.
If now the switchhook is raised, the spring l6 biasing locking lever B, 9 in the box 2, takes control, turns the lever 8, 9 into locking position and forces plunger l0 and wire Hi to the left so that plunger Hi again rises to the position shown in the drawing. When the button 3 is depressed,
lever arm 9 engages the member 5 and locks the J1 support having a, plunger member operable upon removal or replacement of the telephone instrument on the support, comprising spring-controlled means, and a motion-transmission wire engaged at one end by said spring means for attachment to and movement with the plunger member.
3. An attachment for a, telephone instrument support having a plunger member operable upon removal or replacement of the telephone instrument on the support, comprising means for looking the plunger in position upon removal of the instrument, said means comprising a flexible cable attached at one end to said member, spring-controlled means at the other end of said cable, and a manually operable member associated with said spring-controlled means.
4. An attachment for a telephone instrument support having a plunger member operable upon removal or replacement of the telephone instrument, comprising means for locking the plunger in position upon removal of the instrument, said means comprising a motion-transmission wire for attachment at one end to said plunger, and spring-controlled means at the other end of said wire.
5. An attachment for a telephone instrument support having a plunger member operable upon removal or replacement of the telephone instrument, comprising a casing, a bracket within said casing; a lever, a push-button and spring means on said bracket, and a motion-transmission wire having one end within said casing engaging the lever and another end outside of said casing for attachment to the plunger member of said instrument support. 7
