TELEGRAPH OR-TELEPHONE CALL MECHANISM.

SFECIFICATION forming part of Letters Patent N o. 665, 134, dated January 1, 1901. Application filed March 21, 1900. Serial No. 9,571. \No model.)

To aLZ whom if; may ooncera:

, Be it known that I, EDGAR E. SALISBURY, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented new Improvements in 'lelegraph or Telephone Call Mechanism, of which the following is a full, clear, and exact description.

This invention relates to improvements in telegraph and telephone call devices; and one object is to provide a simple mechanism for releasing the break-wheel upon an upward movement of the receiver-s11pportingarm and also for locking the said arm in its upper position and releasing it after the rotation of the break-wheel; and a still further object is to provide a simple means for winding and releasing the call mechanism without removing the receiver or disturbing the supporting- 2o arm therefor.

I will describe a telegraph and telephone call mechanism embodying my invention and then point out the novel features in the ap-' pended claims.

Reference is to be had to the accompanying drawings, forming a part of'this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is an elevation showing the re- 0 leasing mechanism and the supporting-arm connections. Fig. 2 shows the device for releasing the break-wheel independently of the supporting-arm. Fig. 3 is a view similar to Fig. 1, but showing the parts in a diiferent 5 position; and Fig. 4 is a, sectional view.

Referring to the drawings, 1 designates a casing of any suitable material and in which is arranged the frame 2, supporting the operating parts, which comprise the ordinary o spring-motor for rotating the break-wheel 3, which coacts with a contact-plate 4, with which one of the linewires is connected, while the other line-wire is designed to be connectedito the call mechanism, which is in electrical connection with the break-wheel 3, in the usual manner. Oppositely arranged on the break-wheel are two outwardly-extended stop-lugs 8 9, designed to be engaged by a lug 10 on a locking-lever l1, pivoted to 5 0 one of the frame-plates, as clearly shown in Fig. 1. This locking-lever is moved downward to engage with either one of the lugs 8 or 9 that may be within the path of the lug 10 by means of a spring 12. The locking-lever 11 has a curved portion 13, which will engage over the end of the arbor 21, and extended outward from the end of this curved portion is a finger 15 for a purpose to be hereinafter described. A pin 16, attached to the hub 14, is designed to engage with the lockiug-lever 6o 11 to move it out of its connection with the pin or lug 8 or 9, when the arm 7 is moved upwardly by a spring 17, connected at one end to said arm and at the other end to a plate of the frame.

As a means for preventing the arm 7 from being moved downward before the breakwheel shall have made its necessary rotation I employ a locking device for said arm, here shown as an angle-lever having a hook portion 18 adapted to engage with a pin extended inward from the arm. This locking device has a downwardly-extended member 19, designed to be engaged by a pin 20, attached to the arbor 21. When the pin 20 is reposing against the member 19, the spring movement would have completed the break-wheel revolution, and the arm-7 should be in its upward position. This engagement of the pin 20 with the lever i9operates to draw the hook 8o portion 18 inward sufficient to relieve the arm 7, so that when the receiver is replaced on the hook said arm will be drawn down to its normal position by the weight of the receiver. Also attached to the arbor 21 is a pin 22, designed to engage with the finger 15 when the device is to be wound and released without removing the receiver from the receiver-supporting arm.

On the innerend of the arbor 21 is a toothed 0 wheel 23, designed to be engaged by a pawl 24, pivotally connected to a lever 25, to which one end of a spring 26 is attached, the free end of said spring being secured to the frame. The pawl 24 is held yieldingly by means of a 5 spring 27. a

In operation, assuming that the lug 10 of the locking-lever is in engagement with one of the pins 8 or 9 and the receiver is holding the arm 7 in its downward position, with the arbor 21 wound sufficiently to cause the break-wheel to make one-half revolution,

upon removing the receiver the said arm '7 will be drawn upward by the spring 17, so

that the pin 16 by engaging the lever ll will move the lug out of engagement with the pin on the break-wheel, thus allowing the breakwheel to be rotated by its spring. After the arm 7 shall have been moved to its uppermost position the hook l8 will swing underneath the pin on said arm, preventing its downward movement until the break-wheel shall have rotated, and during this movement the arbor 21 also rotates, causing the pin 20 to engage with the part 19 of the locking-lever, moving the hook out of engagement with the pin, so that the arm 7 will be again moved downward to its normal position with the receiver supported thereon.

Should it be desired to signal without removing the receiver from the supporting-arm, the lever 25 is to be moved downward, so that the pawl 24, engaging with a tooth of the wheel 23, will rotate the arbor, causing the pin 22 to engage with the finger 15, and lifting the locking-lever 11 out of its locking engagement with the break-Wheel, so that it may be rotated by the spring action of the spring movement.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In a telephone and telegraph call mechanism, a break -wheel, a locking device for said call mechanism and break-wheel, a receiver-supporting arm, a hook-lever for locking said arm in its upper position, means carried by said arm for releasing the break-wheellocking lever, and means for releasing said locking-lever while the receiver-supporting arm is in its lower position and supporting the receiver, substantially as specified.

2. In a telegraph and call mechanism, a break-wheel, a locking-lever for said call mechanism and break-wheel, a receiver-supporting arm, means carried by said arm for releasing the break-wheel-locking lever, a locking device for said arm when in its upward position, said locking device being adapted to hold the arm until after the call mechanism has completed its full action, and means for releasing said locking device from the arm after the break-wheel shall have made its proper movement, substantially as specified.

3. A telegraph and telephone call mechanism, comprising a breakwvheel, pins extended from said break-wheel, abreak-wheel-locking lever, having a lug adapted to engage with either one of said pins, a receiver-snpporting arm, a pin carried by said arm for engaging with the break-wheeHocking lever, to release the break-wheel upon an upward movement of the arm, a main arbor, a toothed wheel on said main arbor, and a yieldingly-held lever carrying a pawl for engaging with said toothed wheel to rotate the main arbor, substantially as specified.

i A telegraph and telephone call mechanism, comprising a break-wheel, a receiversupporting arm, an angle locking-lever having a hook adapted to engage with a pin carried by said supporting-arm, a spring adapted to quickly raise the arm to its locked position upon a removal of the receiver, and a pin carried by the main arbor for engaging with an extended member of the angle locking-lever to release the supporting-arm upon a completion of the break-Wheel movement, as set forth.

5. In a telegraph and telephone call mechanism, a break-wheel, a main arbor, a locking-lever for the break-wheel, a toothed wheel on the inner end of said main arbor, a spring yielding lever, a stn'ingpressed pawl carried by said lever and adapted for engaging and operating the toothed wheel, a pin carried by the arbor for releasing the locking-lever from the break-wheel, and a receiver-supporting arm mounted to turn on the arbor, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDGAR E. SALISBURY.
