AUTOMATIC QARL-AYNNUNCIATYOR.

To all whmn it may concern;

Beit known that L DAVI D HENRY MAR- srIAIJL, a citizen of'the United States,'resid ing at KansasCity, in'the county of J ackso'n and State bf Missouri, have inventeda new and useful Automatic Car Annun'ciat'or, of which the following is a specification:

My invention relatesto certain new and useful improvements in car annunciators, and has for its object to providean'annum ciator that will indicate the street or'station as approachedautomatically.

Another objectof my invention is to provide'an annunciator that is especially adapt ed to be used on cars operated by electricity.

A further object of the invention is to pro vide an alarm'in connection with the anm'mciator, so that the passengers will be notified when the name of a streetappears in the annunciator. l

I/Vith these objects in view my invention consists of the novel features of construction and "combination of parts, hereinafter' 'described, and pointed out in the claims.

In the drawings forming a part of the specification, Figure '1 is a sectional view through a car, showing the annunc'iator 'in lace. Fig. 2 is a front view ofthe annunciator with the front removed. Fig. 3 isa side view of the annunciator with 'one side removed; Fig. 4 is a front view of the guide way carrying the block. Fig.5 is a sectional view taken on the line 5 5 of Fig. 4. Fig. 6 is a transverse section of the guideway, showing the supporting-frame partly broken away. Fig. 7 is a detail view of my improved trolley and its connections, and Fig; 8 isa detail view of the trolley.

Referring to the drawings,'A indicates the boX inc-losing the annunciator, whichis provided'with the ordinary sight-opening A, arranged in the front and being protected by a pane of glass A -Secured in the casings are the uprights B and B, connected together by the bars B and the bolts B Mountedin the uprights B and B are the shafts C and C, provided with rollers O and C carrying the belt C, which passes over the bars B? and having the names of the streets'o'r stations printed thereon. The ends of the shafts eX- tend through the uprights B and are provided with gear-wheels C and C meshing with a large gear-wheel D, journaled on the shaft D, secured in the uprights B. The

outer face of the wheel D is provided with outwardly-projecting lugs D for the purpose hereinafter described: Extending out-from tl1e"uprights"B" are bolts E, carrying the frame j E, which is provided with the guidew'ay F, slida'bly mounted on the-upperand lower bars'oftheframe'E. The guideway F consists of a flat plate'F, having its ends F bent'in'the form' ofa tube fitting over the bars of theframe E; as shown in Fig. 5. The sides F adjacent the ends F are cut inwardly at and are bent upwardly at F and inwardly at F plate is provided with an" outwardly-projecting wrist-pin F carrying the shifting lever F so thatt'he plate F can'beadjusted to either end ofthe frame E desired. Sliding in the guideway Fis 'a block G, havingan arm G extending therefrom and outwardlyextendi ng shoulders'G providedwith' grooves G fitting over the inwardly projecting sides F of' the plate F. The block'G'is provided with an opening G in 'which *is mounted a pivoted pawl G adaptedtoengage'the lugs D of the gearwheel'D on its upward stroke and revolve the'said wheels.

Securedto the bolts B is a bracket II, carrying a double"solenoid magnet I, having a double cor'eor armature I" cooperating there with, to which is pivotally connected a rod I the other end of which ispivotally connected to the arm G of'the block G. The magnet I and armature I are provided with contact-plates "I which are connected by wires I to the battery J and bell K, so that when the armatures are drawn up the circuit bell willring, notifying'the passengers that a street or station is near. This current for exciting the solenoidmay be derived from any means desired;'but I preferably employ a contact 'shoe L, carried by the trolley-wire M, having a horizontal portion L, adapted to engage the contact-piece N, carried by the fork N of the trolley-pole N. Connected to the co'ntact-piece N is a conductor 0, which passes down the trolley-pole N through the solenoid and is'grounded through the wheel and track. I

A contact-shoe L'is placed'on the trolley M, near each of the streets or stations that are printed on the belt 0". As the car comes along the contact-piece N comes in contact will be'compl'eted through the'plates and the v The operation of the device is as follows:

with the shoe L, and the current is carried down through the conductor and through the solenoid I to the ground. The solenoid, being excited by the current, pulls upon the armatures I, which raise the rod 1 and with it the block G, carrying the pawl G whichblock G on its upward stroke, will revolve the gear-wheel D in an opposite direction.

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

1. The combination in a carannunciator, of rollers carrying a belt, gear-wheels for operating said rollers, a gear-wheel provided with lugs and meshing with the gear-wheels, a guideway slidably mounted on a frame, a block sliding in said guideway, a pawl carried by said block, and means for operating the said block, for the purpose described.

2. The combination in a car-annunciator of a casing having shafts mounted therein, carryingrollers, a belt mounted on said rollers, gear-wheels carried by said shafts, a gearwheel provided with lugs and meshing with said gear-wheels, a frame arranged adjacent said gear-wheel, a plate slidably mounted on said frame, a vertically-reciprocating block mounted on said plate provided with a pawl and a lever connected to said plate, for the purpose described.

3. The combination in a car-annunciator, of rollers carrying a belt, gear-wheels carried by said rollers a gear-wheel meshing with said gear-wheels, a frame arranged to one side of said gear-wheel, a plate slidably mounted on said frame, a block slidably mounted on said plate, carrying a pivoted pawl adapted to engage lugs arranged on said gear-wheel, means for operating said block together with means for shifting said plate, for the purpose described.

4. The combination with a casing provided with a sight-opening,'ofa frame arranged in said casing, rollers arranged in said frame above and below said sight-opening carrying a belt, gear-wheels arranged on the end of said rollers, outside the frame, a gearwheel provided with outwardly-projecting lugs mounted on said frame meshing with said gear-wheels, a frame arranged to one side of said gear-wheel, a plate slidably ranged in said casing above said frame connected to said block, for the purpose described.
