To all whom it may concern: alarm box. Fig. 2 is an end View ofthe same. Be it known that I, LEONIDAS G.WOOLLEY, Fig. 3 represents aA perspective of the yoke a citizen of the United States, residing at Kenand the lever, showing them connected.

Upon the inner end of the oted spring-actuated yoke provided with inshaft of this armature are secured both the ternal shoulders upon opposite sides and pinion I and lug J, which revolves with the which regulate the turning of the armature, armature and which operates iu connection and a connecting-link extending upwardly with the pivoted yoke K for the purpose of 3o from the yoke and having its upper end pivmanipulating the armature.

When the yoke is defrom the yoke, combined with a lever, to pressed, the lug is released from the lower 45 which the upper end of the link is pivoted, shoulder and catches on the upper one. Then and a spring-actuated wheel having projecwhen the yoke rises the lug is released from tions upon its periphery, the lever and the the upper shoulder and again catches on the yoke being operated by the same spring, as lower one. This armature is caused to rewill be more fully described hereinafter. volve by means of the large wheel N, which 10o 5o In the accompanying drawings, Figurelis is secured to the springdrum O, provided a side elevation of a mechanism for a lirewith teeth upon its outer periphery, and

which drum each time the yoke is" manipulated causes the armature to make half a revolution. By manipulating the yoke either through the key M or in any other way the armature may be made to revolve so as to give any number of electrical impulses, so as to transmit the number of the box.

Upon the shaft P of the drum O, outside of the drum, is secured a ratchet Q, with which the pawl R engages for the purpose of preventing the spring from unwinding and with which ratchet also engages a second springactuated pawl S upon the lower end of the winding-lever T, and which lever is pivoted at its lower end upon the shaft P. After this lever T has been used in the usual manner to wind the spring in the drum O theleverT is turned up into the position shown in Fig. 2 and held out of the way by means of the catch U, lwhich engages with a pin on the side of the lever, as shown.

Pivoted to the outer upper corner of the yoke K is a rigid connecting-link V, which is pivoted at its upper end to the lever W, pivoted at its outer end to 011e of the upper corners of the frame B, and which lever has a V-shaped projection X upon its inner end to engage with the wheel Y, provided with projections upon its periphery to indicate the number of the box. Secured to the base at any suitable point is a spring` Z, which bears upon the outer lower corner of the yoke K, and thus causes the yoke to be forced upward, and the lever W has its projection X forced upwardly against the wheel Y through the rigid connecting-link V, which connects the yoke and theinnerend of the lever. Thus by a single spring I make the yoke and the lever W automatic in their action, and when the lever W is manipulated by the wheel Y the yoke K is operated at the same time, so as to allow the armature to make half-revolutions, and thus send impulses to headquarters, so as to give the number of the box being operated. The wheel Y is provided with projections upon its periphery, as shown, and which projections are arranged according` to the number of the box, and these projections passing over the projection X upon the'end of the lever W operate the yoke K and allow the armature to revolve. This wheel Y is operated by a spring A', having one end secured to the shaft C', upon which the wheel Y is placed, and to the opposite end of the shaft from the wheel is connected a train of gears B', which forms a step-by-step escapement for controlling' the speed at which the Wheel Y shall revolve in sending in the number of the box when an alarm is given.

Extending across the top of the frame B is the endwise-moving slide D', which has the spring E'connected to one end, so as to cause the slide to move outwardly whenever it is left free to move by the endwise movement of the slide F', which is manipulated by a key G', and which key causes the slide F' to move sufiiciently far endwise that its end H',

which catches over the end of the slide D', is withdrawn, as shown in Figs. l and 2, to allow the slide D' to be forced outwardly the full length of its movement by the spring E'. Secured to this slide D' and projecting up wardly is the post l', which moves with the slide, and from the top of which post projects the horizontal arm or catch J', which catches under the end of the vibrating arm K' of the escapement. As long as the slide F' is forced backwardly, as shown in Fig. l, this post l' and its arm J' are moved backward sufliciently far to prevent the vibrator K' from engaging therewith, and hence the spring A' will cause the wheel Y to make a full revolution and thus send the number of the box to headquarters the number of times the group of projections upon its surface are repeated. As here shown, there are five sets of these projections, and the number of the box is transmitted iive times to headquarters. After the wheel has revolved its full distance the projecting` pin L' comes in contact with the stationary stop M', projecting upwardly 'from the top of the frame B. Each time the box is operated the chief or some one in charge must open the box and through the thumb-wheel N', secured to the wheel Y, turn the wheel entirely around, ready to be operated again.

This invention difl'ers from the devices now in use only in having the wheel Y under the tension of the spring A', so that each time the box is operated the wheel revolves once, and the spring must then be wound up again before the wheel can be made to make another revolution.

As shown, the key G' has its operating part which engages with the slide F' bent so that after the slide F' has been forced backward into the position shown in Fig. l the key cannot be released until the chief or one who has the box in charge comes and opens the door, when the key is withdrawn on the opening of the door. Connected to thisslide F' is a spring O', (shown in Fig. 2,) which when the end of the slide D' is forced backward by the chief causes the slide F' to spring back into its normal position, with its end H' across the end of the slide D' for the purpose of preventing the escapement from operating and allowing the spring A to unwind and the wheel Y to revolve.

Besides doing away with the use of batteries or other constant source of electrical energy by using the magneto electric machine, a great saving in the cost of batteries or other eleetromotive power is effected and l am enabled to use much lighter conductingwire than can be used in connection with a battery. The batteries being of a low tension, a heavy conducting-wire is necessary, and this wire is liable to be broken down by sleet or ice or by violent winds, which is not the case where a steel wire of No. llt or No. 16 gage is used, which l find to be amply sufficient.
