PHASE-COM PLETING DEVICE.

SPECIFICATION forming part of Letters Patent No. 552,553, dated January 7, 1896.

Application filed March 28, 1893.

.To all whom it may concern,.-

Be it known that l, JAMEs T. SIBLEY, of Clinton, Huron county, Province of Ontario, Dominion of Canada, have invented a new and useful,Phase-CompletingDevice, of which the following is a speciiication.

Figure l of the drawings is a view of the device with the switch lifted out of contact and in position to be forced down by an impulse through the coils of the magnet; Fig. 2, a view of the same with the switch down and contacts closed and the switch locked in place, the dotted lines showing the position of the armature-lever when down and the full lines showing the lever and its pivoted arm when it has passed behind the bracket. Fig. 3 is a view of the same with pin on end of the pivoted arm l)s in position to force cut the arm d' and unlock the switch. Fig. 4 is a view of the pivoted hanger on the end of armaturelever and showing position of the spring for operating this hanger to throw its lower end to the right; Fig. 5, a view of the pivoted hanger on center; Fig. 6, a view of pivoted hanger forced to the other side and its spring ready to throw it back.

Viewing Fig. l, A is a frame, of wood or other suitable material, provided with the binding-posts o. a2 a3 ai. Upon this frame is suitably mounted the electromagnet B, provided with its armature-lever b/ and retractin g-spring b2. The dotted lines on Fig. 3 show the connections with the binding-posts and the line, so that an impulse through the coils of the electromagnet will operate its armature-lever and a break will allow it to be retracted by its spring. l

The switch C is pivoted at c'. lts normal position is drawn up by the tension of the spring c2, as shown in Fig. l. On the end of this switch is placed the contact c3, made of suitable conducting material and arranged to make contact with the plate ci when forced down. Attached to the spring is the bracket c5, and this bracket is provided on one side with the projection c6, and on the other side it is slightly rounded. The bracket c5 and projection c may be made in two pieces instead of solid, as shown in the figures. On the switch O is also placed a lug, as c7, to 3o-operate with Serial No. 467,937. (No morlel.)

a checking or locking device herein after fully explained.

Suitably pivoted to a part of the frame is the hanger D, provided with the arms d (Z2. The lower ends of its arms are forced to the right by the spring d3 and to the left by the downward movement of the armature-lever b.

On the end of this armature-lever is pivoted j the arm b3, which near its lower end is provided with a pin or projection b4. When the switch is down the arm d2 comes in contact with the lug or projection c7 and holds the switch in position until the arm is forced off of the projection by the passage of the pin h4 between the bracket c5 and the arm cl, the action of the pivoted arm b3 is controlled by the spring b5 secured to the armature-lever at one end with its other end resting on the top of the arm. The action of this spring on the arm h3 is illustrated in Figs. 4, 5 and 6. Vhen the arm is hanging plumb the spring rests upon the plane top surface of the arm, as shown in Fig. 5. Vhen it is out of plumb, with its lower end to the left of a plumb-line, the spring rests upon the upper left-hand corner of the arm, as shown in Figs. 3 and 4. Then it is thrown to the right of a plumb-line the spring rests upon the upper right-hand corner of the arm, as shown in Figs. l and 6. Viewing the position of the parts, as shown in Fig. l, it will be seen that an impulse through the coils of the magnet will force down the armaturelever and the switch until the contacts e'1 are closed, as shown in Fig. 2, which also shows in dotted lines the position of the armature-lever and the arm b3. At this point the hanger D has been forced out by its spring cl3 until the arm cl2 has passed above and over the lug cl, holding the contacts c3 c4 closely together. The circuit through the bindingposts a3 a4 is then closed and remains closed until it is opened by another impulse. In this closed position of the contacts the spring b5 is resting upon the upper right-hand corner of the arm o3, as shown in Fig. 6. Then the armature-lever is released and drawn back by its spring b2 the pin lrL passes up beyond the top of bracket c5, when the spring b5 throws the arm to the left in the position shown in full lines in Fig. 2, and ready when it descends IOO to enter the pin b4 behind the bracket and between it and the arm d1. When another impulse is given and the arm descends the position of the spring h5 is changed and rests upon the upper left-hand corner of the arm, as shown in. Figs. 3 and 4, and in descending actuates the arm d, disengaging the arm d2 from the projection c7. The switch is then thrown up by the spring c2. At the same time the action of the spring b5 on the arm b3 throws the pin h to the other side of the bracket, when it takes its position on the seat c(5 ready for another impulse to close the contacts c3 c4. rlhus with each impulse the current in that circuit is opened or closed.

The above description represents the action of the device when used upon an open magnet-circuit and its operation in response to impulses; but it will be seen that the same device may be used upon closed circuit by using the retracting-spring of the armaturelever to close the contacts and the impulse through the coils of the magnet to open them.

It will also be seen that the device may be operated by hand and without the use of the magnet B, and that it may also be operated in connection with any other device as well as a switch. For example, by connecting a semaphore or other device to the end of switchbar C it would be thrown to safety by one movement of the switch-bar in a forward or downward direction, and with the next forward movement of the actuating-arm D the locking devices would be released and allow the semaphore to be returned to danger.7

That I claim, and desire to secure by Let-l ters Patent, is-- l. In a phase-completing device provided with an actuating arm therefor, having a forward and a backward movement, and devices for impelling the arm a iixed distance to thereby complete the throw of the phase-completin g device, in combination with locking devices actuated by said arm in its forward movement whereby the phase-completing device is locked and retained in position while the arm is withdrawn to complete its backward movement, and releasing devices actuated by the next forward movement of said arm an in combination with locking devices actuated by said arm in its forward movement, whereby the phase-completing device is locked and retained in position,while the arm is withdrawn to complete its backward movement, and releasing devices actuated by thc next forward movement of said arm an equal distance to thereby throw out the locking devices, and allow the retractile spring to restore the phasecompleting device to starting point.

3. In a circuit changing device the coinbination with a switch as C provided with the bracket c5, of an armature leverprovided with a pivoted arm as h3, the spring b5, arranged in. connection therewith, to throw the arm h3 to one side or the other of the bracket as required.

4. In a phase-completing device provided with an actuating arm therefor having a forward and a backward movement and devices for impelling the arm to complete the throw of the phase-completing devi ce an equal distance with each forward movement, in ccmbination with automatic locking devices to hold and retain the phase-completing device at the end of its course while the impelling devices are withdrawn, and a guiding device, whereby the impelling devices are directed to actuate the phase completing device to the end of its course, and to unlock and release the same at the next forward movement.

Signed at New York, in the county of New York and State of New York, this 22d day of March, A. D4 i893.
