merit. shown there is a spring motor, but I do not desire to be limited to this type.

G represents the contact piece which is adapted to cooperate with the disks on the rotary contact member and it conveniently made in the form of an arm having a widened portion g with a square extending through it.

H is a stationary shaft mounted in the casing parallel with the shaft Q and passsquare opening in the contact piece. The member G is therefore capableof being slid along the shaft H and may also be oscillated upon the same. I have found that the combination of the sou-are hole and round shaft permits the movable contact piece to slide very freely along the shaft and to be free from binding when itgrasped for the purpose of movbe member G has a handle which projects outwardly through a: eloiigated slot I in the casing. The upper wall of the slot is notched indicated at is, tl notches corresponding in number and in location to the of the rotary contact member. The inner end of the contact piece is provided with av heavy counterweight G so that the inner end of the contact piece always hangs down as far it can go. Upon the inner end of the contact piece is a yieldable contact finger L which is adapted to engage ivith the projections on each of the contact disks when the handle is moved into the notch corresponding to that disk. in Fig. 4 the movable contact piece is shown in its idle position, corresponding to the position which it occupies in Fig. while in it shown in a position opposite one of the disks on the rotary member. l has been In this latter position the handle broua it to rest within the notch corrcspm'ulhole g lifted by the counterweight until ing to he disl-I opposite which the movable contact piece lies; the contact linger L being in position to be engaged by the bias or projections (7.

tends constantly to actuate the rotary con tact member. In order to restrain the ro- "ary contact member when no signal is to be given or alarm sounded, I provide the shaft C with a radially projecting arm M which is adapted to be engaged by a movable abutment and thus hold the shaft against further rotation. In the arrange ment shown the abutment takes the form of an uprightbar 0 hinged at its lower end to a ho izontally slid-able bar 0. A bracket 0 on the horizontal bar limits the swinging; movement'of the upright bar in one direction. A spring 0, secured, at one end to the lower end of the member 0 and at its other end to a part of the casing, tends to hold the slidable bar in the position wherein the member 0 is clear of the end of the stop member MI The spring also serves to hold the member (l against the bracket 0' and thus hold the member 0 upright. The opposite end of the member O is bent up at a for engagen'ient with the lower cud of a lever l which is pivotally supported. on the :asing as at 7) at a point between its ends. The upper end of the lever P pr0- jects above the stationary shaft H. On one side of thc moyablc contact piece is fixed a wedge block (i which. when the Contact piece is moved into its idle position, enters behind the upper end of the lever l", as indicated in Figs. 2 and 4-. and swings the lever sullicicntly to cause the member 0 to be brought into the path of movement of the stop arm on the rotary member. jsl hen the movable contact piece is shifted into one of ills working; positions, the wedge member passes from behind the lever l and the spring 0 returns the parts to the positions indicated in Fig. (3; the member 0 being now clear of the path of movement of the stop arm. it may happen that the movable contact piece is brought into its idle position just a her the stop has come intoealine ment with the upper end'o'f the al'ultment niemliier. injury to the parts is prevented, when this occurs, by reason of the tart that; the spring; 0 permits the member to yield as indicatod in Fig. 7. thus permitting the As soon as the stop arm clears the abut mcnl' member, the spring returns the latter to the position indicated in 5 so that. after the rotary member has ((illll-Dlflltll almostanother revolution, l'liu slop arm strikes upon the upper end of tho abutment member as indicated in Fig. 4

In Fig. I have. Show one arrangement c-f circuit cannecuinns which may be emplnyed. There is a 1003i. circuit for the magnets S and T and aisl.) a Meal circuitwhiuh directly controls the main signaling circuit. This permits the use (if :i small and a heavy current far actuating or nonof iiie pnszsibiiiiy that snmaiiiingg will burn out. Tn prevent dang-gar ii'vm this snnrce X- cnrrent through the controlling apparatus deenergi" d, ihe disk coniinnes in ililil'l nniii .forms part trolling the actual signal devices. Referring to Fig. 10, V represents a conventional bell which I have shown as an example of any signal or alarm which it may be desired to employ. Current for operating the signal is talren from wires V and V these wires leading from a lighting circuit, a power circuit or some other suitable or convenient source. 'W isa relay for closing the circuit through the signal device. X is a battery or other suitable source of current for energizing the coil 10 of the relay. One terminal of the battery is connected to one terminal of the relay and the opposite terminal of the battery is connected by wire 1 to the switchU. From the switch U a con ductor including a resistance N extends to the rod or shaft H. The other terminal of the relay coil is connected to the motor F by means of a wire 2, the motor and the shaft. C being in electrical connection with each other so that no further conductors are required to complete the circuit from .the motor to the rotary contact member. It will be seen that whenever the movable contact piece G is shifted so as to bring its contact finger into operative relation to one of the contact disks, a circuit will be established from the battery through wire 1, through the switch U, through the resistance N,

shaft H contact iece G the rotar contact a P 5 Ii "member, the motor, wire 2, the coil w of the relay and back to the battery. Conse-' quently the relay is'energized and the signal set in operation. As the rotary contact member revolves, the circuit is interrupted and completed and again interrupted, successively, as one projection after another wipes past the finger on the member G. Therefore, as long as the controller remains in operation the relay will be energized and dc'onergized so as to operate the signal through a series of cycles each of which of a predetermined code" the whole code being represented by the differ nt cycles which may be obtained throughout the Whole series of contact disks. For signals of a general character the same relay and signal device or devices are employed. The elcctroma miets S and '1 are arranged in series with each other and with a. battery Y in a circuit controlled by a suitabl v swi ch Z. The switch Z, as heretofore explained, may be actuated manually or b means of a suitable program clock. actuating circuit for the magnets S and T is simple and can easily be traced, so I. shall not describe the wiring 'in detail. The local signaling circuit is the same for general signals as the one heretoLore described except that from switch U a branch 3 leads to the contact piece Q. \Vhen the member G is in its idle position the local signaling circuitis the same as heretofore des'cribed except that from switch U the current passcs to The wire 3, to contact piece Q, and thence to the rotary contact member. Consequently as the rotary contact member revolves the.circult is made and broken as one tooth of the disk D after the other comes into engagement with the contact finger g. It may sometimes happen that the general signal is to be given at the time the other controlling devices are in operation. As I have hcretofore explained, it is desirable that the general signal shall prevail regardless of the other controlling mechanism. The purpose of the resistance N is now clear. If the contact piece G is in a working position at the time the controlling mechanism for the general signal is brought into play, two par allel circuits exist between the switch U and the rotary contact member. The resistance of the branch which contains the contact piece Q is negligible while the branch which includes the contact piece G contains the re sistance N. This resistance is not great enough to interfere with the operation or the relay in the ordinary use of the men'iber G but-it is sutlicient. to reduce the current which passes through the member G when both of the movable contact pieces are in working positions so that control of the relay is taken away from the member G.

While I have illustrated and described only a single preferred form of my invention, and one combining all of the various novel features ofmy invention, I do not desire to be limited to a device embodying all such features in combination with each other or the particular structural details thus illustrated and described; but intend to cover all forms and arrangements which fall within the terms employed in the definitions of my invention constituting the appended claims.
