SUPPORT FOR TELEPHONE-RECEIVERS.

Application filed May '7',

ing the inconvenience, fatigue and annov-v ance incident to using one hand for holding the receiver to the ear.

The invention has for its ob ect to provide a support of the nature aforesaid whichmay be readily applied to telephones generally in use, it being understood that the appliance is provided in a form to meet the style and nature of instrument in use in any particular locality.

A further purpose of the invention is the provision of a support for the receiver of a telephone which admits of adjustment to adapt the receiver to the convenience of the person using the instrument, also to provide novel and peculiar connections whereby the usual receiver hook may be operated automatically to throw the instrument into and out of connection.

The invention consists of the novel fea tures, details of construction and combinations of parts which hereinafter will be more particularly set forth, illustrated in the accompanying drawings and pointed out in the appended claims.

Referring to the drawings forming a part of the specification: Figure 1 is a view in elevation of a telephone instrument of the desk type provided with a receiver support and operating means for the receiver embodying the invention, the full lines showing the receiver supported in operative posit-ion and the dotted lines illustrating the position of the receiver when lowered and the instrument cut out. Fig. 2 is a side view of the receiver showing the clip or attaching means for connecting the same to the supporting arm. Fig. 3 is a perspective view of the presser bar lever.

Corresponding and like parts are referred Specification of Letters Patent.

Patented Feb. 22, 1910.

1909. Serial No. 494,551.

to in the following description and indi cated in all the views of the drawings by the same reference characters.

The appliance comprises a support 1 for receiving the operating parts, said support being secured to the instrument in any manner according to the type or make of instrument. A clip 2 is provided at the lower end of the support 1 and serves as securing means for attaching said support to the stand 3 of the telephone instrument. A series of ratchet teeth at are pro vided along the upper portion of the support 1 and are adapted to cooperate with the receiver supporting arm 5 to hold the same in an adjusted position. An arm 6 is secured at 7 to the support 1 and is provided at its free end witn a cross head 8 to provide an extended bearing for the arm 5 when the latter is elevated into opera tive position. The inner end of the receiver supporting arm 5 terminates in a point which is adapted to engage with the teeth 4 so as to hold the arm in the required elevated position. A longitudinal slot 9 is formed in the inner end portion of the arm 5 and receives an expansion spring 10 which normally presses the pointed end of the arm 5 into engagement with the cooperating ratchet teeth 4 so as to prevent casual displacement of the inner end of the arm therefrom. A pin or headed stud 11 secured to the pivoted arm 6 is arranged to operate in the longitudinal slot 9 and serves to connect the receiver supporting arm 5 to the arm 6. The longitudinal slot 9 admits of the arm 5 having a limited longitudinal movement whereby its inner end may be engaged with or disengaged from the teeth 4. The spring 10 obtains a hearing at one end against the fastening l1 and at its opposite end upon the inner closed end of the slot 9, hence, the spring normally serves to press the arm 5 inward or toward the support 1.

The receiver 12 may be connected to the outer end of the arm 5 in any manner. As shown a clip or support 13 embraces the receiver 12 between its ends and is attached to the bent end 14 of the supporting arm 5. The clip or support 13 may be of any construction to firmly and securely hold the receiver but yet admit of the receiver being readily detached therefrom or placed in position. The clip 13 is also of such construction as to prevent its marring the receiver in any manner.

The hook for supporting the receiver is indicated at 15 and is of ordinary construction and operation. VJhen the hook is depressed the talking circuit is interrupted and the bell circuit established and vice versa. Inasmuch, as the receiver 12 is not suspended from the hook 15 in accordance with the present invention, it is necessary to provide equivalent means for operating the hook 15 whereby the talking circuit may be interrupted when the receiver is lowered and established when the receiver is elevated into operative position. For this purpose a presser bar 16 is provided and is arranged so that its lower end is in contact with the receiver hook 15. A lever 17 is pivoted to the support 1 at 18 and is of the bell crank type, its short arm 19 being pivoted to the upper end of the presser bar 16 and its long arm terminating in a lateral extension 20 which projects into the path of the arm 5 to be engaged thereby and when the receiver is lowered as indicated by the dotted lines in Fig. 1 thereby depressing the bar 16 and the receiver hook 15.

The invention may be readily adapted to difierent styles and makes of instruments, it being understood that in certain localities certain types of instruments predominate and the attachment may be constructed so as to be readily adapted to these instruments. The support 1 is provided with attaching means whereby it may be firmly and readily secured to the instrument, the cooperating part-s attached to the support 1 being relatively disposed for conjoint use with the parts of the instrument to which the appliance is fitted.

Vhen the arm 5 is moved from the dotted line position indicated in Fig. 1 to the operative position shown by full lines, the inner pointed end of said arm automatically engages with the ratchet teeth 4. As the arm 5 is elevated at its outer end, and the lever 17 is released and the receiver hook 15 being relieved of the weight of the receiver rises in the well known manner thereby throwing the talking circuit into operation. Nhen through using the instrument, the arm 5 is drawn outward a distance to disengage its inner end from the ratchet teeth so that the arm may be swung into a pendent position and coming in contact with the lateral extension 20 of the lever 17 operates the latter and depresses the bar 16 whereby the receiver hook 15 is lowered.

From the foregoing description, taken in connection with the accompanying drawing, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.

Having thus described the invention, what is claimed is 1. In means for supporting the receiver of a telephone, the combination of a support provided with a series of ratchet teeth, an arm projected from said support, an arm carrying the receiver and provided near its inner end with a longitudinal slot, a fastening extended into the slot of the receiver arm and carried by the arm extended from said support, and a spring located in said slot and normally pressing the receiver arm inward to hold its inner end in engagement with any one of the series of ratchet teeth.

2. In means for supporting the receiver of a telephone, the combination of a support provided with a series of ratchet teeth, an arm projected from the support, a receiver arm both pivotally and slidably connected to the arm extended from said support, and adapted to engage with any one of the series of ratchet teeth of said support, a spring cooperating with the receiver arm for normally pressing the same inward, a lever extended into the path of the receiver arm, and a presser bar adapted to be actuated by said lever for depressing the receiver hook.

In testimony whereof I affiX my signature in presence of two witnesses.

ROBERT ZINSMAYER.
