.Application filed. Bccember 22, 1910. Serial 1'30. 598,720.

struction of a signaling-device adapted to be manually setand released, and when released to transmit its signal independently of the manually operated actuatmg-means,

whereby the transmission of the signal is then entirely'out of the control of the op erator; also to construct a signaling-device, whereby the signalingcircuit contacts are closed only a short but predetermined period of time, long enough, however, to cause the operation of a certain recording-instrument or other si'gnalreceiving device which may be employed to receive the signal, but not long enough to operate other signal-receiving instruments which may be used in conjunction therewith and adapted to respond to other signaling-devices; also to provide the signaling-device with means for temporarily trapping the. key, while the signalingdevice is being set. Such a signaling-device is of particular importance in signal-systerns, such as shown in my application for l Letters Patent #555,602 filed April 15,

1910, Where two sets of signaling-devices are employed; one adapted to close the circuit for short periods of time and the other for longer periods of time, the closures of the circuit for the different periods of time being employed as a means of differentiation. Such a signaling-device is also adapted for 1 other uses.

The signaling-device embodying my invention comprises circuit-closing members,

an operatingdevice therefor, an actuatingspring for said operating-device, a winding or actuating-member for said spring adapted to be operated by a key or otherwise, manually,'and means for arresting the operating-device while the actuating-member is being operated to wind the spring and for releasing said operating-device when said. actuating-member has been moved forward a sufficient distance to properly wind the spring, and for arresting" the actuatingmember when the operating-device is released, to thereby hold said actuating-member while the operating-device is operating the circuit-closing members and thus prevent any manipulation thereof which might interferewiththe proper transmission of the signal. The signaling-device also includes means for subsequently releasing said actuating-member and permitting the return of the parts to normal.

The signaling-device also comprises means for temporarily trapping the keywhile it is being turned to set the signaling-device in condition to transmit its signal and to release the signaling-device thus set, permitting its withdrawal however, only, when the signaling-device has. been set and released, thus insuring the proper transmission of'the signal whenever the key is inserted and turned.

the actuating-member being arrested by the locking-device and the operating-device be ing moved by the actiiating-spring to operate the circuit-closing members.

0/. represents a suitable shell or case containing the operating-parts and the supportmove said pawl toward the ratchet-wheel.-

' The ratchetwheel b has a deep notch 6, out i in its edge, which is formedwith straight side walls, and the pawl (Z normally occupies a position with its lug d at said notch, but held out of the deep portion thereof by a lug If, as shown in Fig. 2 which projects forward from the plate It on the escapewheel. At the beginning of the forward movement of the ratchet-wheel said pawl is lifted by the inclined side of-the deep notch of'the ratchet-wheel engaging the lug (Z and its cross-piece (Z is raised and held-in the path of movement of the lug h on the operating-device, to thereby arrest forward movement of said operating device, and said pawl will be held in such engaging position by the ratchet-wheel, while the latter revolves,even when bottoming in the interdental spaces, and until the deep notch b is again brought into position beneath the lug 03 During this time saidpawl also acts to prevent backward rotation of the ratchetwheel by engaging the ratchet-teeth thereof.

In Fig. 4, the ratchet-wheel is represented as partly turned, the pawl is elevated, the crosspiece d thereon is engaged by the lug h, and the operating-device is arrested. When the ratchet-wheel has been turned a complete revolution or. thereabout and theactuatingspring has been wound, it is then necessary to disengage the lug h from the pawl to permit the operating-device to be revolved by the actuating-spring, independently, and to accomplish this result, at this particular time only, the deep notch b in the ratchet wheel arrives in position beneath the lug (Z on the pawl, and said pawl being no longer held in elevated position by the ratchetwheel, is moved by the pressure of the lug it upon the cross-piece d far enough to permit the high to pass over the cross-piece. The lug it being thus disengaged, the operating-device will be revolved by the spring in the same direction as the actuatingmember was turned to wind theactuating-spring. As the pawl is moved to disengage the lug h, its lug d enters the square part of the notch 6 far enough to positively lock the ratchet-wheel, see Fig. 5, and in such position acts to hold the actuating-member at rest while the operating-device revolves independently thereof. Vhen the pawl thus enters the square part of the notch?) and looks the ratchet-wheel, it will be prevented from being removed therefrom while the opcrating-device is revolving by the inner edge of the ring j, on said. operat-ingdevice, which moves over the crosspiece during such time. This ring f", however, has a notch 7 also on the inside, which arrives in position above the cross-piece as the operatingdevice resumes its normal position to allow the pawl to be again lifted. Just before the 0peratingdevice comes to rest the lug 7L2 on the plate h and extending forward from it, will engage the cross-piece (Z and lift and hold the pawl above the squared left hand side of the deep notch 5 thus again releasing the ratchet-wheel for another operation.

It will thus be seen that while the actuatingmember is being operated to wind the actuating-spring, theoperating-device is locked, and while theoperating-device is moving to operate the circuit-closing members, the actn ating-member is locked, and for simplicity of construction the s ame-locking-device is employed for accomplishing both results, said locking-device being first moved by the i actuating-member to lock the operating-device, and then temporarily held in locking position, and then released to release the operating-device, and upon release of the oper ating-device is then moved by the operatingdevice "to lock the actuating-member, and finally is moved to release said actuatingmember. Thus the actuating-member and operating-device alternately controlthe operation of each other, each operating. to prevent the operation of the other during its own operation, but leaving the other free to operate at the end of its own operation.

To arrest forward movement of the operating-device at the end of its complete revolution the forwardly extended lug 71 on the plate 72/, is arranged to travel in the path of movement of the lug 6 on the actuatingmember, and to engage said lug b, at such time; and, as at this time the part to which the inner end of the actuating-spring is attached is in engagement with the part to which the outer end of said spring is attached, said spring cannot further cause relative operation of either part.

In Fig. 2, wherein the parts are represented in their normal positions, it will'be observed that the lug 71- on the operatingdevice is in engagement with the lug 6 on the actuating-member, but is disposed at the back side of said lugbi so that the actuating-member is free to be moved forward by the key. As the key is turned and the lug b ratchet-wheel, the operating-device will follow until arrested by the lug h engaging the cross-piece 0Z It will also be observed that just before said ratchet-wheel has been turned a complete. revolution said lug b will be brought to the opposite side is moved forward with the by a forward movement of the actuating.

ating-device into position to release said .opcrating-device and lock the actuating-memher when said actuating-member has been.

moved forward a predetermined distance, substantially as described.
