UNITED STATES PATENT OFFI E.

FRANK C. WATKINS, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE UNITED STATES KROTOPHONE CQMPANY,

OF NEW YORK, N. Y.

TELEPHONE-HOOK.

SPECIFICATION forming part of LettersPatent No. 357,053, dated February 1, 1887.

Application filed May 13, [886. Serial No. 202,112. (No model.)

To all whom it may concern:

Be it known that I, FRANK O. WATKINS, a citizen of the United States, residing at Philadelphia,in the county of Philadelphia and State 5 of Pennsylvania,- have invented certain new and useful Improvements in TelephoneHooks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

referencebeing had to the accompanying drawings, and to the letters and figures of reference marked thereon,which form a part of this specification.

My invention relates to improvements in telephone-hooks; and it consists in certain novel features, hereinafter described and claimed.

In the drawings, Figure 1 is an elevation, and Fig. 2 is a cross-sectional view, of my devlce.

Referring to the drawings by letter, A represents the ordinary box containing the callgenerator; B,the receiver, and G the telephonehook.

G is a bar pivoted at or near one end upon the box A. The free end of this bar engages a fiat spring, E, upon the end of a raised metallic plate, D, secured to the box. The generator or eal1-wire is connected to the plate D, and the line-wire conneotswith the plate D.

E F are two flat metallic springs,which are secured to the box at a distance below the bar 0, and within the circle described by its long arm as it swings downward in. the operation of the device.

Wires G H run from the springs E F, respectively, and form part of the transmitter and line circuits.

The hook O is pivotally supported between two ears or lugs secured to the outside .of the box, and has an extension, 0, which is inserted through a passage, 0 in the side of the box, and the bar 0 rests upon this extension.

In operation, the'telephone not being in use, the receiver is hung upon the hook O, and its weight will hold the bar 0 in the position shown in the drawings. When it is desired to use the telephone, a current is sent from the generator through the plate D, the bar 0 and the hook O, and the plate D to the line wire over which it passes to the call-bell or signal at the other end. The call being answered, the receiver is taken from the hook, when the extended portion of the hook will fall and allow the bar 0 to drop and engage the springs E F, when the telephone will be ready for use, as will be readilynnderstood.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

In combination with the telephone-box, the hook-bar pivotally supported upon the outside of the box and supporting the receiver upon its outer or hooked end its other or free end extending through a slot in the side of the box, the bar 0, pivoted at one end to the in-' side of the box and having its free end supported by the free end of the hook-bar, and the metal springs arranged above and below the bar 0, substantially as set forth.

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

FRANK O. WVATKINS.
