UNITED STAT S I GEORGE W. HEY, OF SYRACUSE, NEW YORK.

CIRCUIT-CLOSER.

SPECIFICATION forming part of Letters Patent No. 520,427. dated y 2 1894- Application filed March 11, 1 8 93.

To aZZ whom/it may concern:

Be it known that I, GEORGE W. HEY, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Circuit-Closers, of WhlCh the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My present invention relates to improvements in electric circuit closers, and has for its object the production of a simple and practlcal device, which is economically manufactured, is durable and effective in use, and is easily and practically operated by an electric circuit or other apparatus connected to move one of the terminals of the circuit closer to and fro, and to hold the same in its operative position; and to this end it consists, essent1a1ly,in a movable terminal, a second terminal movable toward the former terminal, and means for forcing the movable terminal from its operative position for releasing said movable terminal when in its inoperative position and for holding the second terminal in operative position.

The invention furthermore consists in the detail construction and arrangement of the parts, all as hereinafter more particularly described and pointed out in the claims.

In describing this invention, reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all thevlews.

Figure 1 is an elevation, partly in section, showing my improved circuit closer applied to a selective automatic circuit-closing mechanism, which forms no part of this present application. Fig. 2 is an elevation of parts of the mechanism shown at Fig. 1 illustrat ing particularly my present invention enlarged and in its inoperative position. Fig. 3 is a horizontal sectional view, taken on line 3-3-, Fig. 1, additionally illustrating my improved circuit-closer, and the mechanism to which it is applied. Fig. 4 is a rear elevation of the parts as shown at Fig. 2. Fig. 5

is a detached rear elevation of the separate terminals of my circuit closer, the weighted lever carrying one of the terminals, and the connection detachably connected to said le- Serial No. 465.4:86- (No model.)

ver, the parts being shown as in their normal position with a lost motion between said weighted lever and connection. Fig. 6 is a simil'arelevation of the parts as shown at Fig. 5, the connection being shown as in en gagement with the engaging projection of the weighted lever, and Figs. 7 and 8 are similar elevations, the weighted lever being shown in its inoperative position at Fig. 7 and the terminals as in contact at Fig. 8.

I have shown the circuit closer as forming part of a selective or automatic signal operating circuit closer, but it will be readily understood that the same, although particularly adapted for use as a part of said circuit closer, may be separated therefrom and may The terminals 0 D are carried by any suitable supports, the support for the terminal 0 consisting of a lever c and that for the terminal D of the armature lever b of the magnet B, which is provided with an upturned terminal carrying arm I). The lever c is preferably hinged at one end upon a pin c, and is provided at its'other end with a Weight or enlargement c and the terminal O- is arranged between the two extremities of said lever and is formed with a beveled face. The armature lever b is hinged at its lower end upon a pin b is provided between its two extremities with an armature B, and at its upper end with an insulated arm -b to which the lower end of the terminal arm bis suitably secured. The pivotal pin c-- for the lever c is carried by any suitable support as an arm e provided on a supporting frame E, and the pin -b is mounted lna similar support as a lug e'- upon said frame. The terminal D- is directly beneath the lever c, and is normally separated from the terminal -O', and, as the magnet B is energized, the armature lever .b is rocked toward said magnet and the terminal -D is forced toward the terminal (J to its operative position. As the circuit A is broken by the action of the switch A or other suitable means the magnet --B loses its magnetism, and the armature lever b is retracted by a suitable spring or other retractive mechanism E connected to return the lever -b and the terminal D carried thereby to their normal inoperative positions.

F is a connection or link for preventing contact of the terminals C-'D as the magnet B is energized and the terminal D- forced to its operative position. To effect this result the connection F rocks the lever c upwardly to its position shown at Fig. 7, and releases said lever so as to permit the same to fall downwardly by gravity and permit the engagement of the terminals OD, providing the termina D- remains in its operative position. The weight of the support or lever c, and particularly the Weight of its enlarged end 0 is the means for bringing said support to its normal position, but it is evident that a suitable spring or other similar device may be used for this purpose. This connection F is preferably hinged at -fto the armature lever b-, and is provided with a shoulder for engaging a tooth or projection c upon the pivoted end of the lever -c. The shoulder fof the connection F and the engaging projection -c of the lever -care preferably so arranged and constructed that, as best seen at Fig. 5, there is a slight lost motion between said parts for enabling the connection --F to elevate the lever c by a well defined impact againstits tooth c Consequently the force of the blow given to the lever -c rocks the same upwardly with great rapidity and the projection c swings forwardly from engagement with the shoulder -f' of the connection -F and an inclined face -f extending downwardly and inwardly from said tooth rides upon the hub of the lever c, as clearly shown at Fig. 7. The connection -F is, therefore, detachably engaged with the lever c, and the lever 'c, after being forced to its elevated position, is free to assume its normal depressed position, and, if the terminal D remains in its operative position, the terminal C is engaged thereby. The practical engagement of the terminals is facilitated by the weighted end of the lever c, which rocks the terminal -O firmly against the terminal --D. Suitable stops OC regulate the upward and downward movement of the lever c, and consequently as the armature lever b is rocked toward and away from the magnet B- by the passage of current pulsations over the circuit A, and by the retracting mechanism -E- the lever -c is continually forced upward and permitted to fall downward. On the contrary, if the armature B of the armature lever -b remains in engagement with the magnet B., the terminal D remains in its operative position, and the terminal C is engaged therewith upon the descent of the lever c.

As is clearly illustratedin the drawings the support for the terminal 0 is integral therewith, and the support for the terminal D is separable and insulated therefrom, but it is evident that both terminals may be formed separable from their supports and insulated therefronnand that both terminals may be formed integral with their supports, providing said supports are insulated from each other.

The terminals C-D are connected to the circuit -A by the respective wires A A and, when in contact, a magnet A connected to the wire A is energized by the current from the battery a-. As the 'circuit from the terminal O is through the hinge pin c' of thelever c'- carrying said terminal I connect said lever and pin bya coiled electric conductor ---O, which acts also as a springbfor returning the lever -c to its normal position.

The magnet A is shown as provided with an-armature gcarried by a lever G, which is connected by a link g' to one end of a lever G-, and is proyided with a terminal -g connected atits inner end to a circuit wire g The opposite end of the lever G is engaged with astop dog g and with a feeding dog gfor the ratchet wheel or disk G for forcing said dogs out of operative position. The

feeding dog g is shown as supported on the armature lever b, and said lever is provided with a stop dog g. The ratchet wheel --G is provided with a lug which engages a pivoted terminal g' connected by its pivotal pin g and the frame -A to a second circuit wire -g-. It will be understood, however, that the ratchet wheel G its feeding and stop dogs, the arma ture lever -G, the lever -G' connected thereto, and the circuit wire -g g form no part of my present invention and consequently it is unnecessary to further illustrate or describe said parts.

It will be readily understood from the foregoing description and upon reference to the drawings that my improved circuit-closer is longer duration than the passage of the current pulsation, which merely brings to its operative position the terminal normally out of operative position and immediately retracts said terminal to its normal position before its engagement by the remaining terminal.

In the present example of my invention I have shown one of its most simple and economlcally manufactured constructions, and 1t will be readily noted that the same consists of a m nimum number of parts, which are economically manufactured, are readily assembled, and are effective and durable in operation. It is evident, however, that considerable change may be made in the detail construction and arrangement of the parts, and consequently I do not herein limit myself to the exact detail construction and arrangement of said parts.
