SIGNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 533,014, dated January 22,1895.

Application and May 27. 1892. Serial Ne.434,635. (N model.)

T0 at whom it may concern: 1

Be it known that LBERNIOE J. NoYEs, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in 5 Signal-Boxes, of which the following description, in connection 1 with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

Prior to this invention signal boxes have to been provided with local alarms which are sounded when the latch, or knob of the door of the box is turned, or when a glass fitted in the front of the box is broken, to render aocessible the pull or hook by means of which the signal transmitter is operated. The person pulling in the alarm is sometimes deceived by the local alarm, presuming that when sounding, the fire alarm or signal is being transmitted, although such boxes have been plainly marked.

This invention has for its object to provide a signal box containing any suitable alarm, or signal transmitting apparatus, with a local alarm operating mechanism adapted to be automatically let off, or operated when the door of the box is opened or a glass fitted in the front of the box is broken, and to simultaneously let off, or operate the signal transmitter, so that whenever said local alarm is '0 sounded the transmitter will be automatically operated, and the signal transmitted, without requiring the person at the box to pull the hook after opening the door, or after said local alarm has sounded, or during the time it is sounding.

This invention may be carried out in many different ways, but as herein shown the signal transmitting apparatus, and also the local alarm operating mechanism, bot-h comprise 40 normally wound motors, which when released, operate to perform their respective duties, yet said motors may be normally unwound, and the operating parts so connected together that when the local alarm is operated, the

4 5 signaltransmitting apparatus will also be operated.

Figure 1, shows in front elevation, a signal transmitting apparatus and local alarm operating mechanism, and intermediate connection between them, whereby the signal transmitter and local alarm operating'mechanism,

are both set in operation by the act of opening the door, said parts being removed from their inclosing box or case; Fig. 2, a detail of I the let off orreleasing device; Fig. 3, a front elevation of the signal box with the door opened, and Fig. 4t,"a front elevation of the box with the door closed; Fig. 5, a detail to be referred. to.

The signal transmitting apparatus herein shown consists of a suitable frame, a toothed driving wheel a, mounted on the winding shaft 0., journaled in said frame and carrying a pawl a which engages a'ratchet wheel disecured to said shaft. I, p

The wheel a, engages a pinion'w, ona shaft carrying a toothed wheel a which latter en gages a pinion a, secured to a shaft carrying an escape wheel M, with which co-operates the pallet a The signal Wheel a is secured to the shaft carrying'the toothed wheel of, and suitable contact pens 0. are provided which engage Said signal wheel.

The wheel a carries a stop pin a which 7 5 enters a notch in a locking lever 0. pivoted to the frame at a and carrying a pin a, which enters a recess between the ends of flanges a a", on the wheel a, when the train is at rest, and which bears upon one or the other flange when the train is in motion, to thereby keep the locking lever in elevated position while the signal wheel a", is making several revolutions. I

A hook or pull b, is provided, which is adapted to lift one end of the locking lever (1 to release the train.

This form of signal transmitting apparatus is well known, but in lieu of it, any other well known form may be employed.

The local alarm mechanism comprises a gong 0, adapted to be struck bythe hammers c, on the pallet 0 of the normally wound train, consisting of the toothed driving wheel 0 mounted on the winding shaft 0 and con- 5 nected therewith by the pawl and ratchet in the usual manner, a pinion c engaged by said toothed wheel 0 a toothed wheel 0 securedto the shaft carrying said pinion, and the pinion c engaged by said toothed wheel, and secured to a shaft carrying an escape wheel 0 with which said pallet 0*,00-0pe12tt68.

A projection c, is secured to the pallet c which is engaged by one arm of a bell crank lever 0 see Fig. 2, pivoted at 0 the other arm of said lever normally bearing against a plate of glass e fitted in the door 0 or it may be against the door 0 itself, the glass plate not being employed.

A rock shaft d, is mounted in suitable bearings, having at one end a short arm d, Fig. 5, which terminates justbeneath the end of the locking lever 0, and has at its other end a short arm (1 which is connected by a link 01 with one arm of the bell crank lever 0 The short arm 01, is made of suitable length so that when raised to lift the locking lever, the latter slips off, or is disengaged, and on the end of said arm a small block (1" is hinged which permits the arm to pass beneath the locking lever, thereby resuming its normal position.

The operation is as follows:'VVhen the door 0 is opened, or when the glass plate 0 is broken, the bell crank lever 0 is released, letting off the local alarm train, which causes the pallet 0 to move the hammers, and strike the gong, and at the same time that said bell crank lever 0 is released, the shaft d is rocked moving the locking lever a, and releasing the signaling train, so that it will be seen that whenever the glass is broken or the door opened and the local alarm operated the signal will be transmitted. The door 0 is not provided with a lock, but simply with a latch, which is operated by the handle e, that said door may be opened without the aid of a key, and hence the box resembles what is commonly known as a keyless box. The glass plate is inserted in the door for the reason that many people can readily understand that to send an alarm they must break the glass, but as above implied said glass plate may be omitted.

Instead of employing the particular construction shown of intermediate mechanism connecting the two trains, any other form may be employed, and furthermore instead of connecting the releasing or operating lever of the signalingtrain,with the releasingoroperatinglever 0 or with the local alarm it may be operated independently by breaking the glass or opening the door. The box is also provided with a door 0 by which access may be had thereto, and a slide bolt 0 is arranged on the inner door 0 which when moved in one direction passes beneath a pin moving in aslot 0 and secured to the link d so that the trains may be held at rest while the doors 0 and 0 are opened for inspection, and on the inner door 0 a similar slide bolt 0 is arranged which when moved in one direction passes beneath the lever 0 to hold the trains while the door c ,'is being opened for inspection, but in lieu of these particular locking devices any other equivalent forms may be employed.

I claim- 1. A signal box provided with a door, asignal transmitting apparatus, and a local alarm mechanism in said box the operating levers of both of which are automatically moved to operate their respective apparatus and mechanism by opening of said door, substantially as described.

2. In a signal box, a signal transmitting apparatus, and a local alarm mechanism, the operating levers of both of which are simultaneously and automatically moved by the breaking or removal of a removable front plate, substantially as described.

3. In a signal box, a signal transmitting mechanism, and a local alarm mechanism, combined with a keyless door for controlling the operating lovers of said mechanisms, and a locking device to positively lock said mechanisms when the said door is open for purposes of test, 850., substantially as described.

4. In a signal box. a signal transmitting mechanism, and a local alarm mechanism, and two inner doors 0 and 0 and locking devices thereon for said mechanisms combined with two outer doors a, 0 the latter being keyless, and controlling the operating levers of said mechanisms, substantially as described. t

5. In a signal box, a signal transmitting apparatus, and a local alarm operating mechanism, the operating lever of which is controlled by a removable front plate, and connections between said local alarm operating mechanism and the signaling train, whereby the latter is operated by the forme'r,substantially as described.

6. In a signal box, a signal transmitting mechanism, and a normally wound local alarm mechanism, the releasing lever of which is held by a removable front plate, and interposed connections between said mechanisms, whereby the signal transmitting mechanism is operated by the local alarm mechanism, substantially as described.

7. In a signal box, a signal transmitting mechanism,and anormally wound local alarm mechanism, the releasing lever of which is held by a removable front plate, the rock shaft d and arms (1, (Z and link d connecting the arm 61 with the local alarm mechanism, substantially as described.

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