POLICE SIGNALING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 447,059, dated February 24, 1891. Application filed July 28, 1887- Serial No. 245,499. (No model.)

To all whom it may concern:

Be it known that I, BERNICE J. NOYES, of Boston, county of Suffolk, and State of Massachusetts, have invented an Improvement in Police Signaling Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention has for its object to construct a signal-box especially adapted for police-signaling purposes which maybe cheaply made and capable of transmitting; certain fixed or determinate signalsas a box-number, for instance-and certain special signalsas a wagon-call, for instanceand certain variable signals, as numbers by which the officers are known.

In the present embodiment of my invention one or more circuit-changing devices or pens are adapted to be rotated in the arc of a circle by means of a suitable motor, movement of which is effected. by an actuating-pull, and a permanent signal-controlling device, consisting of a series of studs or projections, lies in the path of movement of the circuit-changin g devices or pens to co-operate therewith in effecting the changes in the circuit.

The box is herein shown as adapted to transmit the boxnumber, either alone or in conjunction with a special signal or with a variable signal-as the officers number, for instance. The permanent controlling device which co-operates with the circuit-changing devices in sending the box-nu mber is preferably located upon the, rear side of the faceplate of the box, and the face-plate is provided with an opening in the arc of a circle described by the rotating circuitchanging devices or pens, into which opening the special signalcontrolling device is placed. The special signal-controlling device consists of certain proj ections on the rear side of the door of the box, so that when the door is closed the controlling device will enter the opening sufiiciently to co-operate with the rotating circuit-changing devices, the box at such time being operated by an outside key. Then the box-door is open, any variable circuit-controlling device maybe placed in the opening in the face-plate to co-operate with the said circuit-changing devices and effect the transmission of said variable signal in conjunction with the boxnumber.

The variable signal-controlling device is herein shown as a curved plate having upon one side of it a series of studs or projections,

and it is designed that such controlling devices shall be used to effect the transmission of a number by which the officer is known,1t being, as herein represented, his individual number.

Should the box be employed in cities having but a few officers, I will employ but one row or series of studs or projections upon the plate; but if there are quite a number of officers I will employ two concentric rows or se-' ries of studs or projections, followed by the other, which will co-operate with the other series of studs or projections, and so, also, if many boxes are desiredsay more than ten or less than one hundred-the studs or prosignal-box embodying this invention,the door of the box being open; Fig. 2, a diagram of the receiving apparatus at the receiving-station; Fig. 3, a rear side view of the face-plate of the box removed; Figs. 4 to 7, inclusive, enlarged details of the circuit controlling and changing devices to be described. Fig. 8 is a sectional detail of a portion of the box-door and face-plate, the former being closed. Fig. 9 is a top View, and Fig. 10 aside view, of the signaling-train shownin Fig. 3.

The transmitting apparatus inclosed within the box A (see Fig. 1) is supported on the rear side of the face-plate A, (see Fig. 10,) fitted into the box or case A. The transmitting apparatus consists of one or more circuit-changing devices, two, as a I), being herein shown. These circuit-changing devices are substantially alike, each consisting of a signalingkey having an upwardly-turned end, as a b, and having circuit-closing contacts 2 3, like unto an ordinary telegraphing-key, although in lieu of this particular form of signaling-key circuit-closing contact-pens, as shown in Fig. 7, may be employed. These keys CL 1) are secured, respectively, to blocks a 17 fixed to the extremities of arms a N, radiating from a shaft 0, such arms being herein shown, for purposes to be hereinafter described, as radiating at an angle of substantially ninety degrees. A counterbalancing-weight c is fixed to anotherarm radiating from the shaft 0 at a point.

between the arms (6 b to counterbalance the weight of the signal-keys a b. This shaftc has its bearings in the face-plate A and the back plate 0, which 'is secured to the rear side of the face-plate A by suitable posts.

The shaft 0 is driven by a motor mechanism of any ordinary construction now commonl y employed in signal-boxes, such motors being wound up by depressing a suitable pull, as (Z, or other winding-arm and operating when said pull is released or duringits return movement. Such form of motor being old. a detailed description of the same is deemed unnecessary.

The circuit of the box, as'represented in Figs. 3 and 10, is as follows: Starting at the plate 30, it extends by wire 31 to a contactpen 32, hearing on the wheel a, secured to the shaft 0, thence along the shaft and by wire to the signaling-key a, circuit-closing contacts 2 3, wire 34, to the signaling-key b, circuit-closing contacts 2 3, wire 35, along the shaft to the wheel e also on said shaft, but insulated from the wheel 6, contact-pen 6, bearing thereon, and thence by wire 36 to the plate 37. Thus it will be seen that the circuit in the box is'normally closed.

A controlling device is herein shown, which co-operates with one of the circuit-changing devices or signaling-keys to effect the transmission of a fixed or determinate signal-as the box-number, for instancesuch controlling device consisting of a series of studs or projections 6, (see Fig. 10 and dotted lines, Fig. 1,) projectinginwardly from the rearside of the face-plate A of the box and arranged in the arc of a circle about the shaft 0 as a center and at such distance therefrom as to lie in the path of movement of one of the sig naling-keysas a, for instance; but, if desired, I may employ two concentric rowsof studsor projections, one of which will co-op erate with the signal-key a and the other of which will co-operate with the signal-key b, it being understood and shown that the signal-key b is arranged on an arm which is shorter than the arm on which the signal-key a is arranged, and thereby describing an are of a circle of lesser diameter. As this plate A is always fixed in position at each and every time the shaft 0 is revolved,tlie signaling-keys will pass over the studs or projections 6, the inturned ends 61/17 striking said projections and moving the keys to open the circuit-closing contacts. These studs 6 occupy butasma l portion of the circle described by said signaling-keys. By placing the two series of rows concentric and arranging the signaling-keys on arms rotating in different arcs one of the signaling-keys-as a, for instancewill pass over one row of studs, and thereafter the other signaling-key, as Z), will pass over the other row of studs, and said studs protrude sufficiently to lift the circuitclosing pens to separate the circuit-closing contacts 2 3 successively as the shaft revolves, thereby sending a continuous signal. At another portion of the circle described by the signaling-key an opening is formed in the face-plate A of the box, into which opening a special-circuit-controlling device may be placed, it finding access to and cooperating with one of the signaling-keysas a, for in stance. This special-circnit-controlling device herein constitutes a special-signal or wagon call, and consists of ashort curved bar or block, as g, (see Figs. 1 and 8,) fixed to the inside of the door D of the box, so that when the door is closed the said bar g will enter within the openingf, so as to be struck by one of the signaling-keysas a, for instancealthough said bar g may be arranged to cooperate with the signaling-key b, or two bars may be employed, if desired, arranged concentrically like unto the rows of studs, and cooperating successively with the signalingkeys.

WVith the box-door closed the motor mechanism will be operated by means of an outside key, which turns a crank-arm and pulls down the bar (1', and when the box is so operated the signaling-key a will first pass over the bar g and open the circuit during a long interval of time. It will then pass over one of the series or rows of studs or projections, and thereafterthe signaling-key b will pass over the other series or row of studs, thus following the dash with a box-number.

By opening the box-door, and thereby removing the bar 9 and operating the pull, the box-number only may be transmitted, unless other means, new to be described, are placed in the opening f to co-operate with the signaling key or keys. \Vhen the box-door is opened, the opening f may receive another form of circuit-controlling device, which is herein designed for each officer to carry with him, said circuit-controlling device consisting of a plate 2', (see Figs. 6, '7, and 10,) having on it a series, of studs or projections i, indicating his individual number, and this plate 71 is so shaped as to fit the opening-f and to bring the studs or projections upon its rear side into proper position to be struck by the signaling-keys as they revolve. These plates IOC ITO

'L' are detachable from the mechanism, in order that they may be carried about, put in op erative position, and removed by the officer. The studs or projections t", which are to indicate the officers number, constitute the characteristic contact devices which are carried by the detachable plate 2'.

Suitable locking devices are provided for the plate i, herein shown as two spring-controlled jaws n n, pivoted to the rear side of the face-plate A and acted upon by the spring n the ends of said jaws passing out through the small openings in the face-plate A to engage and hold the plate 2' when placed in position in the opening.

\Vhen the officer opens the box to transmit his patrol-signal,he places his individual key i in the openingf and then operates the pull and the signal will be transmitted, as heretofore described, it being understood, that this plate at such time takes the place of the controlling device g.

At the receiving-station a receiving-relayr is included in the main line, the armature r of which controls alocal circuit r containing a local battery r and a register 1- The armature 7* also carries a pivoted lever riwhich, when the armature is retracted, entersbetween the teeth of a rotating wheel 0", and is thereby lifted. The armature r has at its under side a hook a, which engages and trips the drop 0- which closes thelocal circuit 4" including the battery 7* and the relay r the armature of which relay is included in the local circuit r normally bearing against the contact-point 8,

but when attracted striking the contact-point 2), thereby cutting the branch wire into the circuit with the register. The bell S or other suitable alarm apparatus is included in the branch wire. By this arrangement the signals, including the dash, will include the bell in the receiving-circuit, and, as herein shown, the dash coming first and the box-number following, the bell will be included and the number tapped out audibly. It is obvious, however, that in connection with the transmitting apparatus herein shown any other suitable receiving apparatus may be employed instead of the particular arrangement and construc tion herein shown-as, for instance, the register alone may be employed, which will be included directly in the main line, if desired. 7
