ANNUNOIATOR.

SPECIFICATION forming part of Letters Patent No. 758,995, dated May 3, 1904.

Application filed May 16, 1903. Serial No. 157,433. (No model.)

To all whom it may concern:

Be it known that I, DAVID HENRY MAE- SHALL, a citizen of the United States, residing at Kansas (Jity, inthe county of Jackson and State of Missouri, have invented a new and useful Annunciator, of which the following is a specification.

My invention is an improvementin annunciators that should be particularly adapted for street-cars, the object being to provide a device of. this description by means of which the names of streets as approached will be shown at the front end of the street-car.

While my device is shown as applied to a street-car, it is obvious that it can be used on any car and that names of stations can be announced as well as streets.

My invention consists of the novel features, combination, and arrangement of parts described hereinafter, particularlypointed out in the claims, and shown in the accompanying drawings, in which- Figure 1 is a perspective View showing the practical application of my device. Fig. 2 is a sectional elevation looking from the rear of the frame carrying the rollers. Fig. 3 is a sectional end elevation, the circuits being shown in diagram. Fig. i is a vertical section taken transversely about the center of the frame. Fig. 5 is a detail view of the circuit-breaking disk and coacting parts. Fig.

7 6 is a perspective view of the parts coasting with the disk, the latter being omitted.

In the above-described figures a rectangu lar casing A is shown as secured above the door at the forward inner end of a car, the casing being provided with. a-front panel of glass A. In this casing is arranged a framework comprising metal end plates B, connected by rods B. Two horizontal shafts are journaled in these end plates, the oneabove the other and designated C and D, respectively. A strip of flexible material E, conopen frame comprising the metal plate G and i its su homin -rods G is carried by the end stub-shaft H is revolubly journaled at one end in the plate B and at the opposite end in the plate G, and on this shaft is rigidly secured a small gear-wheel H meshing with the gearwheel F, and a notched disk H This disk, which is of metal, is in advance of the gears, and the edges of the notch H are covered by any suitable insulating material.

J ournaled in bracket-s J is a sleeve J, having exteriorly formed thereon right and left hand worm-gears J and this sleeve slides on and rotates with a shaft J of the motor J the sleeve being moved along the-motor-shaft by a hand-lever J which is held in the desired position by a spring J The circuit-forming device comprises a rectangular frame K, having a transversely-arranged insulated sleeve adjacent one end, which sleeve fits over one of the rods Gr. This frame is arranged adjacent the disk H and from its upper end an arm K projects toward said disk. An arm K having the two parallelmembers K", is journaled on the sleeve K. At its inner end a roller K is carried between the ,two members and contacts with the disk H A short bar K connects the two members intermediate the roller and the sleeve,.and springs K are connected, respectively, to the end of the frame K and the bar K and said bar and arm K, these springs holding the roller in contact with the periphcry of the disk.

Where the device is applied to cars run by electric power, current is readily supplied to the motor; but where it is used on cable, steam, or horse cars a battery L is arranged at one end of the frame, and for convenience of illustration and description this form is shown.

A bar M is journaled on the rod (Jr above the frame K and is held in position by a setscrew M. At its inner end this bar is diagonally slotted, as shown in dotted lines in Fig. 5, and a copper strip 1W 2 is held in this slot, its lower end contacting with the shaft H.

Running from the battery are the wires L L the wire L being broken and the circuit through same completed by a push-button L located in easy reach of the motorman, gripman, or other party charged with operating the device. Both these wires lead from the battery to the motor. A Wire L runs from the battery, leading from the wire L intermediate the battery and push-button to the copper piece M and a wire L leads from the motor to the arm K The operation of my device is as follows: On pressing the button L a circuit is formed through the motors via wires L L and the rotation of the motor-shaft rotates sleeve J and one of the worm-gears J which one being immaterial, and rotates the gears D, F, and C, and the gear F rotates the gear H and shaft H, thus causing rotation of the disk H Rotation of the disk removes the insulated notched portion H from contact with the roller K and a circuit is established through wires L L, arm K, disk H shaft H, and copper strip M and the motor will continue to work until the disk has made one complete revolution, and the circuit is broken by the roller K again droppinginto the notch H and will I remain broken until the button is again pressed. Rotation of the gears C and D, which are fixed on their shafts, will rotate the shafts C and D and wind the material E from one to the other, the direction of such winding depending on the worm-gear that is in engagement with the gear-wheel D. When the car has reached a terminal and starts back, the hand-lever J 5 is shifted, bringing the oppositely-formed worm-gear into engagement with the disk D and the sheet E is wound in the opposite direction. a

A bell N is arranged in the circuit between the battery or other source of power and the motor and is sounded when the button is pressed. It is obvious that my device may be secured in either end of the car or transferred from one end to the other in case the car is not turned around, or push-buttons may be placed at each end and the mechanism operated from either end without changing its position.

Having thus fully described my invention, whatI claim as new, and desire to secure by Letters Patent, is

1. The combination with a casing, of shafts revolubly journaled in said casing, aflexible sheet adapted to wind from one of said shafts to the other, gearing connecting said shafts, a motor-shaft, a sleeve rotating with and sliding on said motor-shaft, and oppositely-formed worm-gears on said sleeve adapted to drive said gears.

2. A device of the kind described having a circuit comprising therein a revoluble disk having an insulated notched portion, an arm carrying a roller contacting with the periphery of said disk and adapted to rest in the notched portion, a motor in said circuit, a motor-shaft, means whereby rotation of the motor-shaft will actuate said disk, and means for temporarily forming a circuit through said motor independent of the arm and disk.

3. The combination with a casing, shafts revolubly mounted therein, gears carried by said shafts, a stub-shaft, an intermediate gear on said stub-shaft said gear meshing with the gears on the revoluble shafts, arevoluble stubshaft, a small gear on said shaft meshing with the intermediate gear, a disk rigidly secured on said shaft said gear having a notched insulated portion on its periphery, an arm having a roller at one end adapted to engage the periphery of the disk, a motor, a motor-shaft, a sleeve on said shaft having worm-gear formed thereon, said worm-gear meshing with the gear on one of the revoluble shafts, a metallic strip contacting with the revoluble stubshaft, a wire from a source of power to said motor, a wire from said source to the metallic strip, a wire from the motor to the rollercarrying arm, means for initially starting said motor, and a sheet of flexible material, adapted to be wound from one of the first-mentioned revoluble shafts to the other.

4. The combination with a suitable casing, of a frame therein, revoluble shafts journaled in said frame,asheet of flexible material adapted to wind from one shaft to the other, gears on said shafts, an intermediate gear meshing with the first-mentioned gears, a revoluble stub-shaft, a small gear thereon, meshing with the intermediate gear, a disk having an insulated notched portion on said stub-shaft, a motor adapted to drive said gearing, an arm having a roller engaging the disk and adapted to rest in the notched portion, a contactstrip contacting with the revoluble stub-shaft, a push-button, a wire leading from a source of electric power to said push-button, a wire from said button to the motor, a wire from said motor back to the source of power, a wire from said motor to the roller, carryingarm, and a wire from the source of power to the contacting strip.
