This arm has a slight yielding movement against the force of a spring 6 which holds the arm 6 normally in place. The push rod J carries a hook J and is mounted to slide in the frame 11' carried on the base and the bearing 7' and is surrounded by a spring i one end of which engages with a portion of said frame, the other end being engaged by a pin j on the push rod so as to maintain the push rod in such a position as to allow the circuit breaker to remain normally closed. The end of the push rod is provided with insulating material and adapted to engage with the circuit breaker e and brca k the circuit when pushed.

The push rod is normally locked to prevent it from being operated and as shown it is released by means of the armature h operated by the electroma gnet H. The electromagnet at this station is in a shunt circuit which is temporarily operated in the manner below described. The armature h is pivoted at 7L1 and is slotted as indicated at 7L2, a catch it passing down through said slot and adapted to engage under the edge of said slot and hold up the armature from contact with the push rod J when the unlocking of the push rod is desired. Normally, however. the armature is free. The

catch ha is held in position to ride under the armature when the armature is in its highest posit on by means of a spring 71, The push rod J is also provided with a collar 7' which normally engages the end of the armature It so that when the armature is in its lowest position as indicated in Fig. 2 the push rod cannot be moved. iVhen. however, the armature has been attracted by the electroma gnet H it is caught in this upward position by the catch 71 as described and is there held so that the push rod may be moved to open the circuit breaker e (see Fig. 2). This act of moving the push rod forward, however, also releases the catch h from its engagement with the armature as a portion of the collar y strikes the catch so that the armature is in position to fall again upon the return of the push rodand relock the push red. I have indicated the operation of the armature as being controlled by gravity on the one hand and by the magnet on the other. but it is apparent that if the apparatus be laid horizontally the position of the armature may be controlled by a spring instead of gravity. The frame j in which the push rod J ismountecl and the other parts of this apparatus are mounted on an insulated base or otherwise insulated from the box containing the mechanism as indicated in Fig. 4. The apparatus as a whole at each station is inclosed in a box having a base K with a front K having an opening covered by a spring closed door K by opening which the watchman reaches the hook J to operate the push rod J. A partition K incloses the mechanism within the box and protects it from any tampering on the part of the watchman. This partition K has an opening K through which pro jects the fire alarm handle F and in front of this handle is an opening in the front K covered with a sheet of mica K which can easily be broken to turn the handle F 2 as below described.

The fire alarm apparatus is shown in the upper part of Fig. 2 and in Fig. 3. It is connected with the watchmans record so that each time the watchman makes a record at the central office from a given box he also makes a record at the fire station which may be and preferably is in a different location from the central ofiice. My system comprises therefore a record at two different offices, one for example, the central ofiice in the building and the other a fire office which may receive fire signals from any number of buildings; the record at the central o'flice shows whether the watchman is doing his duty as a guard and the record at the fire ofiice showing that he is going his rounds as a fire patrol.

L is a shaft supported in a frame comprising the plates M and M and the posts m, the plate M being attached to the back K of the box. The outer end of this shaft carries a crank F The shaft also carries a clock spring N, one end of which is attached to the shaft L and the other end to the post 11. on the plate M. gear Z free to turn thereon except as it is provided with a pawl Z which engages a ratchet Z fast on the shaft L. lVhen the shaft L is turned one way therefore it turns the gear Z, but when it is turned the other way the gear is stationary. The gear Z meshes with a pinion 72 on the shaft P, supported in the plates M M, so that when the gear Z rotates the shaft P will rotate with it. The speed of rotation of the shaft P is controlled by an escapement mechanism Q of any suitable construction operated by the gear 72 on the shaft P, the pendulum of this escapement being shown at q.

Mounted on the shaft L to turn therewith and insulated therefrom is a wheel B. This wheel comprises a hub carrying three disks 7', r and 1*. The disks 'r and 1' are cut away at r or otherwise arranged so that during a portion of the revolution electrical contacts .9, a, normally resting upon them and hence being in electrical connection with each other will become disconnected from each other. The third disk 7 is cut away for the same purpose and serves as a support for contact 8 which forms a ground connection. These. contacts are supported in a The shaft L also carries a block of; insulating material so as to be n ated V-from each other-and; tro th 0K K.

The disk o? is alsowcut varmy tor mostv of its periphery. v Contacts e0, 10 and wsupported the insulated block rest on the periphery of these disks.

This spring is not shown as it is imilar to the ordinary-re traction spring of an armature to an elec:- tronagnet, but it. is.- preferably somewhat Stronger in order ,ta ive the marker power e adeat th dia The armature is. moimt' with, the arm d as below described. The

eaipparatnsalso includes 'a recorder Z which Rafi-lathe firecircuit and which is operated as below described, simultaneously with the Y and records-the number of the station.

=A similar recorder :Z also in the fire circuit is, located atithe fire -station and makes a similar record there. I prefer to use for this purposes Morse recorder of ordinary type, vAll'these stations are alike so far as the recording mechanism is concerned =so that this'description will answer for the descripftio'n of all theboxes.

will now describe the operation of my system including the above described signal 12 E etc, is completed through the series of circuit breakers, one at each station, is, the wire E runs to the post and circuit breaker c and the circuit is completed through the contact point 6 connected normallyat the -point 6 with the post F, the wirejE and the neXt station, etc-., the connection. at the last stationbeing with the wire E. vThecircuit breaker cl of the watchmanswclock at the central station A is 0perated by means of the rotating dial Y forming part of the clock, one arm (1/ of which engages and lifts the circuit breakerrl of the central station and causes it to make eieotrica l contact with the arm d and throw in station '32 forms what may be tern-red a local shunt through the electrornagnet H,

which electromagn'et is also connected; with the point e and post f so that the circuit is closed through the wires E and E as before; This change of circuit throws the batteryon the electromagnet H energizing it and thereby lifting its armature h for the moment and unlocking the push rod J at this station, the armature when released dropping on the catch h so that it will not interfere with the operation of the rod. The

push rod J is then in condition to be operated. The watchman pushes it to the left 'atthe proper time, this action causing its engagement with the circuit breaker e and breaking the circuit at e and'hence releasing the armature carrying the marker Y and causing the recordingapparatus at the central station to make a puncture in the dial sheet as described above. The move-- ment of the push rod J also moves the lever L which. turns the wheel R approximately a}; of circumference, thus breaking the shunt connection through the contacts 25, and throwing the battery current through the fire alarm circuit. Upon the return of the nection with the shaft 1 By this means the contacts to and 10 are caused to wipe over the periphery of the wheel V, breaking the circuit as they pass the notches so that they cause the recorders Z and Z to make an appropriate record at the central and fire stations. The notches being differently arranged at each station the record from each station is distinctive. The movement of the push rod against the circuit breaker 6 also causes it to make contact with the arm a which functionally corresponds with the arm (Z of the clock throwing into circuit for the instant the local shunt E of box 38 which is connected with its electromagnet H, thus causing the energizing of the electromagnet H in the box 33, and freeing the push rod therein so that at the proper time the watchman may push the rod and cause the making of a record from box 33, this act also setting box 84 through shunt The record is made from box because in the pushing of the push rod J in that box the circuit at e in that box is broken for the instant and hence the current which had been passing from the battery B through the recording instrument A circuit breaker (Z, wire E circuit brez her 0 of box 32, wire E circuit breaker e of box 33, wire E circuit breaker c of box 3-1, and wire E and D being at the moment broken, causes the operation of the recording instrument at the central oflice. It will be seen that this operation may be repeated indefinitely according to the number of boxes in the system. Breaking the last circuit at c throws the current temporarily through E. IVhen the watch man has gone his rounds he can do no more until the dial has rotated far enough to bring the next arm '1 into contact with the circuit breaker (Z so that the same sequence of operations is gone through again by the watchman. The recording dial Y on the clock shows by the punctures in it the times at which the watchman has made his record and this record is confirmed by the recordersZ, Z This record he can only make by visiting the boxes in a definite order.

The opening in front of the box closed by the mica K is opposite the crank F and in case of fire the watchman breaks the mica K and turns the crank one complete revolution until it strikes the pin Z projecting from the inside of the wall K and then lets go. In this case not only are the shunt contacts t, t allowed to separate and break the shunt circuit but the fire circuit is broken as at r for a period representingsay q th'of the rotation of the wheel R during which time the contacts 1', 1' and r are electrically disconnected so that the recorders Z, Z indi' cate a long connected line thus During all this time and until the wheel R stops its rotation the wheel V is constantly rotated, in the form of my invention shown rotating nine times. During its first rotation it can make no record because of the breaking of the circuit while the fingers 8, s 8 are passing the portion 1' of the periphery of the wheel R. hen they again rest on the periphery of the wheel R the circuit is again closed to be broken only as the contacts '0, o, 12 pass over the notches in the i wheel V when the signal represented as follows from box 32 is sent is, viz: etc. Contacts 1 and e are provided connected -with the ground so that in case of any fault on either side of the fire circuit the line will be grounded and the apparatus will still be effective as a fire signal.

In order to make a register at each box of the number of times the box has been used and so have an additional check on the watchman I prefer to connect a counter of ordinary construction to the push rod J. Such a counter is shown at z and in this case it is operated from the lever L by means of the crank 2 which is connected to and operates the lever .2 pivoted to the plate 2 A connection 2 between this lever 2 and an arm on the counter 2 causes it to make a count with each movement of the lever L and push rod J against the force of the spring 2 I have shown two fire signals, one at the central ofiice of the building and one at the fire station. The one at the central office may be a bell or it may be omitted entirely, or the separate fire station may be omitted according to circumstances. For example, in a warehouse or department store system a fire station elsewhere is desirable, but when the property to be protected is a large yard which has its own fire protection the two stations may well be combined in one. The use of a fire and watchmans record at the same central station is very desirable as it enables the manager of the building or property to satisfy himself that the two systems are working satisfactorily. The paper dial on the clock may be divided into fractions of an hour so that a record on it tells the minute at which the record is made by the watchman and a similar mechanism may be used if desired by which to make a record at the fire station.

I do not mean to-limit myself to the precise construction of apparatus shown in the drawings and above described because it will occur to one skilled inthe art that modifications of the apparatus and circuits may be used to accomplish the desired result, and so far as I know I am the first tomake a. combined circuit by which stations can only breasts-ads a gis-n ta..- ans-a.
