each side of said actuating members, a representing the middle arm and a a the outside arms. The several switch-arms are supported by means whereby they are insulate from each other and are attached to an ear of on a supporting-plate a. The actuating members a a each bear contacts at or near their upper ends which are adapted to engage contacts on the outside arms, and the middle arm bears a contact which is adapted to be engaged by a contact on one of the actuating members. This group of spring-acting arms, however, operate the local circuits, so that a detail description of the circuits is not necessary, and said group of switches is herein referred to as the telephone-switch.

Be it known that I, FRANK M. POTTER, J r., of Rome, county of Oneida, State of New York, have invented an Improvement in Telephone-Switch-Operating Mechanism, of which the following description, in connectionwith the accompanying drawings, is a specification, like characters on the drawings representing like parts.

I This invention relates to telephone-switchoperating mechanism, and has for its object to provide improved means for operating the switch automatically when the telephone-receiver, or it may be a combined receiver and transmitter, is removed from or replaced upon the pivoted hook, which is adapted to receive and support it.

One of the essential objects of my invention is to provide means for supporting the telephone-hook at either side of the switch-box, and to this end means are provided for supporting said hook at both sides of the box, to either one of which supports said hook may be connected.

Another object of my invention is to improve the construction of the switch-actuating mechanism.

Figure -1 shows in front elevation the operating mechanism of a group of telephoneswitches embodying this invention, the pivoted hook being depressed. Fig. 2 is a similar view showing the pivoted hook in its elevated position. Fig. 3 is a plan view of the parts shown in Fig. 1. Fig. 4 is a detail of the support for the telephone-switches and guide for the switch-operating arm. ig. 5 is a detail showing a modification of the angularly-formed end on the cross-bar. Fig. 6 shows a modified form of switch-actuating mechanism. Fig. 7 is a vertical section of diverging ends of the springacting arms and thereby operate the switches. The switch-operating arm b works in a slot a formed in an ear a on the supportingplate, and is guided by said slotted ear.

pin b extends radially from the rock-shaft 1), near one or both ends thereof, adapted to be engaged by an extension 0 on the pivoted hook c, which receives upon it the receiver, or combined receiver and transmitter, which elementis hereinafter referred to as the telephone, or in lieu of said pin the ends of the bar are bent at right angles, as shown in Fig. 5, in both instances, however, angularly formed ends being produced. The weight of the telephone depresses the pivoted hook and the extension 0 thereon en ages and lifts the end of the rock-shaft and t ereby turns said shaft on its axis in one directhe switch-actuating mechanism, taken on tion, and also lifts the radially-extended arm the dotted line 7 7, Fig. 6 Fig. 8 is a detail 1) free from the actuating members a aof the switches a. A sprmg d is connected with the rock-shaft for the purpose of turning it in the opposite direction, and said spring is made to encircle the shaft and is permitted to act when the telephone is removed from the book. At each side of the switch-box a support 6 is provided for the telephone-supporting hook, which, as shown in Fig. 1, consists of a pair of ears projecting from a base plate to which said hook is pivoted, and it will be understood that said hook is detachably connected to either one of said supports.

Referring to Figs. 1 to 4, a represents the group of switches, comprising a plurality of spring-acting arms, two of which, as a a, serve as the actuating members and have diverging ends, as shown. These spring-acting arms are arranged side by side, and the two actuating members a a are connected together at their lower ends, while the other arms are arranged one between and one at and making provision for pivoting the hook box and a telephone-supporting hook adapt- 5 c at both sides of the box said hook may be ed to be connectedwith either end of said arranged at either end of said shaft, as shown switch-actuating mechanism for operating it by dotted lines, Fig. 1, and hence may be loin the same direction, substantially as de- 5 cated at either side of the switch-box, and scribed.
