STATION-INDIGATOR.
SPEOIFIGATION f01'ming part of Letters Patent N0. 250,490,da10ed December 6, 1881.
Application filed August 29, 1881. (N0 model.)
T0 all whom z't mag; concern Be il: known that I, JOHN H. BICKLEORD, of Salem, Essex county, State of Massachusetts, have invented an Improvemenb in Station-Indicators, 0f which the following deseription, in conneccion with the accompanying drawings, is a speoification.
My invention relates t0 station-indicators for raiIway-trains, and is shown embodied in that dass of apparatus in which the indicators in the difi'erent cars are included in an electric oircuit, and operated simultaneously by elentric impnlses.
The indicator proper, bearing the names 0f the stations along the route, is actuated by a mechanical motor controlled b v an electromagnet in such a manner that it moves one enbire space to display a new station-sign at; each complete backward and forward movement 0f the annamre of the said magnet, it makingno difference whether the cireuit be nor mally closed and operated by breaking and aga-in closing it t0 prodnee a movemenb 0f the armature and signal 01 normally opened and an electrie impulse a-pplied and then removed t0 produce the said movement; of the indicator. The armatnre 0f the electro-magnet is provided with a bell-hammer t0 strike a Dell, and thus calltheattention 0fthe passengers toohechange of station-sign. The indicating device proper eonsists of tw0 circular disks mounted upon and rotating with a shafb aetuated by the said motor, and adapted t0 receive upon their periphery stripsbearing tha names of the differenb stations, Which thus f0rn1 a cyliudrical drun1. 'lhe said station signs or strips are made (1etachable, so as to be readily replaced by others, as When the mute 0f the car is changed, and the shaft is made detaehable, so that one entire drum can be easily ren10ved and replaeed by another. lhe motor is shown as aetuated bya spring, and is wound by a backward movement of Ehe said drum, Which can readily be turnedback any desired number of steps to bring it to the starting-point 01 t0 enable one drum 110 be put in unison With the others. I have provided a switch by which the controlling-mfignet may be removed from tl1e eircuit, so that the apparatus at the rear of each ear may be cut out or ehe resistance of its magnet the terminals 0f the said two wires together to complete the circuit.
Figure l is a front view of a station-indicator apparatus construc'ced in acoordance With my invention; Fig. 2, an end elevation 0f the m0- tor and its controlling eleetro-magnet; Fig. 3, a detail 0f tl1e escapement 01 stop mechanisrn therefor; Fig. 4, a detail ofthe latches by which the station signs 01 strips are antaehed to the revolving disks; Figs. 5 and 6, top and side views, respectively, 0f the eircuit-connecting devices; and Fig. 7 a diagram illustrating the elect-ric circuit; and. switches.
'lbe indicating device proper consists of tw0 connected disks, a a, the fonner being provided with a series of studs,- 2, and be latter with a series 0f pins, 3, and spring-catches b, (see Fig. 4,) t0 engage and hold in plane the station-signs c, provided with slots4, t0 engage the said suds 2 and pins 3. In attaehing the said station-signs c to the drums a a, one end is plaoed beneath the head of the stud 2, the slot 4 embracing the shank 0f the said stud, and the other end is pressed down upon the pin 3, the eud 5 0f t;he latch b being beveled. and springing aside, and then slipping over and engaging the end of the strip c as shown in Fig. 4. The said disks a a am mounted on a shat't, (l, preferably squared, and eugaging a sockeo', e, upon the end of the arbor e, actuated by the mainspringf, and provided with a ratchet,f, engaging a pawl upon the gear g, loose upou the said shaft e, and meshing With Lhe train 0f wheel-work g g g the arbor of the last wheel of which carries the stop-wheel h, controlled by the arnnature z of the electro magnetj. The train is so-proportioned that a complete revolution of bhe stop-wheel h pern1its a movement of the shaft e just sufficient to move the disks a space equal to ehe width 0f one of'the station-strips 0, so that a new station-strip is displayed ap each rotation 0f the wheel h, the entire apparatus thus far descr-ibed being inclosed in a case, as shown in Fig. l, the front of which is therein shown as open, and is adapted When c1osed to conceal the entire apparatus, except 011e f the stationsrips, which is 111 place behind an open1'ng Which is thereinindicated in dotted lines. Tl1e front 0f the sz1id case will be hinged 1l1eret0 for the pu1pose 01' ob'uainiug re-ady access to theinelosed partsas for changing the stationstrips e when desired.
The armature z is mounted upon a lvver, 1. pivoted ab G, 2111d having: is movement limited by stop-pins 1 the said lever beiug provided ab its lower end with 13w0 pallets 01 lateral projections, 70 k, arranged as shown 111 Fig. 3, the latter being; slightly below tl1e former, and havinq its upper face terminated nearly vertically beneath the upper face 0f the f01n101".
The stop-wheel 71 is provided xyith an engaging projection, (shown as 21 pinh) that in its rotation c mes into engager-nenl: with he pal- 1e1; k if the ar1nature be attracted, 01 the pal- 4 1et k if itbe unattraoted, 2111(1 is released f101n the pal-le1: k in its movement that takes place when the arrnaure is attracted. By this arrangement a double, movvmen of the armature backward und 1orward from either position will release the pin h and perrnit; the wheel 71 t0 make a revolution and the disks a a t0 m0v'e sufficiently t0 bring a new sration-sign. c, into view, and the said disks will always 100 stopped in proper position 10 display a station-sign whatever the condition 01 the electric circu1't may be. A hell-111111111101, 1 ca1ried by the 211- rnature-lever i, strikes ablow 011 ehe hell l 111 the movement 0f the ar1naoure, by Which the pin h is released and the station-sign permi1zted t0 change.
Tbe springfof the motor is wound by turning the shaft: d, together with the indicator, in the backward direction, the said shaft bei11g provided Wi'h a sujtable 1nilled head, d, f0r that; purpose, 211111 the teeth 0f the ratchet f correspond in position with the statiou-signs c, so tha1; by turning the said shafl: tl1e distance 0f one tooth on tl1e ratcbe1; a new 0ne of the said signs will be brought in position behind the opening 0f the case and 1;he differeut; instruments may be set in unison, 01 so as 150 give 1;he san:1e indication tbrougbont the train, by merely turning the said shaf d back until the same sign appears through be opening in eaeh instrument, i1' being understood that each instrument is provided wirh the same number of signs beariug the Same names and zirranged in the same order.
The circuit-wire 9 from one pole of the battery enters ti1e binding-screw 10, which is 00nnected with the pivoted arm m of a switch, 011e 01" the buttons, m, of whicl1 is cunnected with one electrode ot' 1:11e magne1: j, and 1;he other button,w, 0f Which is cnn11ected wi111 ehe 0Lher electrode 0f the said magnet and with the binding-screw 12, from whieu the circuiu is continued 130 the binding-screw 10 0f tue next apparatus. By th1s arrangement, when the switch m is 011 th'e bu1:1un m the magnetj is included in the cireuit; butz when 011 13110 bu1tou m the ci1cu1t pass =s divectly by the saic1 switch 01' the binding-screw 10 to the binding-serew 12, and 1:11e magnetj 0f the instrument veases to operate. A remrnwire. 13, passes tl11ougrhout the train t0 the oth@r pole 0f the battery, Which 1nay be plamd in the baggage-car 01 in any convenient place. The wires 9 13 f10m the differen1: poles 0f the battery are eonnected from 0211 t0 car by a device shown in Figs. 5 and 6, 113 consistingz 0f11w0levers 01 j-aws, n n. pivoted together ab 15 and pressed toward one another bv a sprin;r 0. The s211d jaws consist of two mvtallie portions mounted upon insulatin9: ma-
