` Specification of Letters Patent.

Application filed August 17, 1920. `Serial No. 404,134.

Be it knownthatl, HARRY A. MAYBERRY, a citizen of the United States, and. a resident of McLeansboro, in the county of Hamilton and State of Illinois, have invented anew and usefulv Car-Sign Exhibitor, of which tion. y

My invention relates to street or railway car sign exhibitors and has as its all important object the provision of a sign eX- hibiting apparatus which will lindicate tothe passengers of a car, the street that is .being approached.

Further, the invention Aprovides an autothe following is a specical matic street indicator for street or railway cars whichwill successively indicate thevarions streets approached by the carat a sufficient distance in advance of the streets to give the vpassengers time to signal that they desire to leave the` car at the next stop. l lThe invention also provides an electrif callyoperated automatic street indicator` of this character including a motor and a novel c ircuit` maker and breaker for operating the motor at predetermined 'times.

. With the preceding and other objects and advantages in vmind. the invention consists in the novel combination of elements, constructions and arrangement of parts, operations land specific features which will be hereinafter enlarged upon, claimed and illustratedfin A,the accompanying drawings,

wherein y i.

Figure 1 isa fragmentary view, partly 1n elevation and partly in vertical cross section -of a car equipped with vthe invention;

Fig, 2 is an, enlarged view of an exhibitorremoved from the carparts being broken away;

Fig. 3 is an enlarged fragmentary vertical sectional view ofy the circuit maker and breaker embodied Ain the invention;

Fig. 4 is a fragmentary front elevation of the trolley pole and shoe and one of a plurality of ycontacts arranged at predeter-l mined intervals for engagement by the' shoe; and

Fig.'5 is adiagrammatic view of the electric circuit embodied -in the invention.

Referring to the drawings in detail wherein like characters of reference designate corresponding parts throughout f the several views, thenumeral 5 vdesignates a street car ofv usual construction embodying a trolley pole 6 to theupper end of which an outratentea May 31', 1921.

standing electric contact or shoe' 7 is at` tached.

'The trolley or feedwire and connected with this feed wire 8 at predetermined intervals,

is designated at 8 such as betweenv two l street crossings or stations and i'ntersect-` -1 lng the feed wire 8, is a branch conductor 9 from which depends a contact 10 to be engaged by the shoe 7 upon advance of the car. erably at the forward lend thereof within sight ofthe passengers is a casin 11 provided with a sight opening. l2. l

v orizon tally disposed shafts 13 and 14 are jour-v Arranged within the car 5 and prefnal'ed in the casing 11, each of which car- `v ries a roller 15, and passing aroundvthese rollers 15 is an endless sheetor belt 16, hav ing the numbers or names ofthe streets con#r secutively arranged thereon in the order in which they are approached. i

Supportedon a 'suitable bracket 17 ar.- ranged at the upper end of the casing ll'is an electric motor 18 in circuit with thecar lighting system indicated in its entirety at shaft 20eXtendsv fromthe motor 18` 19. v'A and has one end journaled in one of the sidev walls of the casing 11, and fiXed to the shaft l i 20 adjacent its opposite end are clutch elements 21 and 22. A relatively longsleeve 23 is slidably mounted on the shaft 20 and fixed to oneend of the sleeve is a clutch element 24 to be engagedwith the clutch elei ment 21 andv fixed for rotation with ther clutch element 24 is a drive pulley 25 about which a drive belt 26 is engaged, the latter passing around a drive pulley 27 lixedto one end of the shaft 13 whereby the lower roller 15 is driven in one direction to move the endless sheet or belt 16 in onedirection kto successively exhibit the signs.

A clutch element 28 is fixed to the opposite end of the sleeve 23 and is adapted for engagement with the clutch element 21 when the pulley 25 is allowed to be idle on the shaft 20. This clutch element 28 carries a drive pinion 29 meshing 30 carried by a clutch element 81 slidable on a shaft 32 arranged below the shaft 20 and having one end journaled in a bracket 38 depending from the upper wall of the casing 11 and its opposite end journaled in a partition wall 34 of the casing 11.

The sleeve 23 carries a depending arm 35 adjacent its inner end which is rigid with the clutch elementl, the latter being engaged with a clutch element 36 on the shaft with a gear 32 when the pulley 25 is idle, at which time the gear 30 is in mesh with al pinion 37 fixed to the shaft 14. Slidably mounted in one of the side walls of the casing 11 at its upper end is asleeve 38 provided with an operating knob 39.V This sleeve 3S overlies one end of the shaft and has its inner end enlarged and connected to the clutch element 24 by a yoke 40.

It will be manifest that upon moving the sleeve 38 outwardly the sleeve 23 will be moved' to disengage the clutch elements 21 and 29 and the clutch element 24 engaged I cally secured to both contacts.

with the clutch element 22 to drive the pulley 25 to drive the shaft 13 in one direction and that upon moving the sleeve 38 inwardly, driving connection will be established between the clutch elements 21 and 29 to drive the shaft 14 reversely through the pinions and gears above mentioned.

ln order to operate the motor 18 at predetermined intervals l provide a circuit kmaker and breaker which includes a disk l41 fixed to rotate with the shaft 32 and is provided with a laterally disposed circumferential flange 42. An l -shaped trip 43 is pivoted to the disk 42 at its peripheral edge and one leg thereof normally rests upon the flange 42. A spring 44 engages the trip 43 at its pivot and normally holds the same at a slight tangent with respect tothe disk.

Secured to the bracket 33 is an outstanding plate 45 from which a relatively long electric contact 46 dlepends. A movable contact 47 is pivoted to the plate 45 and is normally urged toward the contact 4G by a contractile spring 48 having its ends Conductors 49 in circuit with the lighting circuit indicated at 19 are electrically connected with the contacts 45 and 47 while conductors 50 in circuit with the lighting system 19 are electriconnected with an electro-magnet 51 supportedon a. bracket 52 secured to one of the side walls of the casing 11. rlhe upper end of the bracket 52 is beveled, and fulcrumed on vthis end is an armature 53 normally reta-ined in aV horizontal position and in the path of one leg of the L-shaped bracket 43 by a coil spring 54 having one end secured to the armature and its opposite end secured to the bracket.

Assuming the parts are in the positions shown in` Fig. 3 and that the shoe 7'carried by the trolley pole 6 engages one of the contacts 10, a circuit will be completed through the coil or magnet 51 attracting the armature 53 to dispose the forward end of the same out of the path of the trip 43, the contact 47 acting under the influence of the spring 48 is then engaged with the staf tionary contact 46 completing the circuit through the motor 18 to drive either the shaft 13 or 14 depending upon the relative position of the clutches above set forth.

When the disk 42 has made one complete revolution the sign sheet will have been advanced sufliciently to dispose one of the signs'in the sight opening 12 and at this time the trip 43 will engage the end of the movable contact 47 and move the same away from the stationary contact 46 to break the circuit to the motor'and as the armature 53 has been returned to its normal position through the medium of the spring 54, the parts will be held in their normal position ready for the next operation.

it is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resortedV to without departing from the spirit of the invention or the scope of the subjoined claims.
