CLEVELAND O. YOUNG, OF CHICAGO, ILLINOIS.

S'IBJELFYI AND STATION INDICATOR...

To all whom it may concern:

Be it known that I, CLEVELAND O. YOUNG, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Street and Station Indicators, of which the following is a specification.

This invention relates to improvements in street and station indicators.

It has among others the following objects: to provide a street and station indicator that is electrically operated, wherein l. vreb is used, having street names fixed thereon; the web being mounted on rolls, and means provided for operating said rolls; to provide means for sounding an alarm when certain names appear having instructions in connection therewith.

One embodiment of the invention'is illustrated in the accompanying drawings, in which similar numerals refer to similar parts throughout the'various views. 7

In the draWings Figure l is a front elevation of the machine, showing a portion of the casing removed. Fig. 2 is an end elevation, having a portion of the casing removed. Fig. 3 is another end view of the invention, showing a portion of the casing removed. Fiat. l is a vertical section on line 4% of Fig. 1. Fig. 5 is a top plan view of the operating mechanism. Figs. 6, 7 and S are details of the machine. Figs. 9 and 10 are partial mechanical and diagrammatical views showing one of the means that may be employed for operating the indicator and electrical circuits employed therewith. Fig. 11 is a detail view of the mechanism for operating the shutters. Fig. 12 is an elevation of a portion of the web upon which the street names are fixed.

Referring specifically to the drawings, 15 indicates a casing of any suitable construction, for containing the mechanism.

16 and 17 are partitions between which the rolls 18, 19 and 20 extend and have bearings.

22 is a web of suitable material, which bears the street names. Roll 19 is provided with teeth or projections 23 that engage holes 2 1 near the edges of web 22.

Rollers 18 and 20 are provided with small gears 25 and 26 respectively. Gear 25 engages agear 27 which is rotatably mounted Specification of Letters Patent.

on a fixed stud 28, and small gear 26 engages gear 29 and is rotatably mounted on a fixed stud 30. A spiral spring 31 is provided having one'end secured to the fixed stud 28 and the other end to gear 27. Another spiral spring 32 is provided; being coiled opposlte to spring 31 and is secured to the fixed stud 30 and gear 29.

A worm gear 33 is'mounted on roller 19 and engages worm 3 that is fixed on shaft 35. The said shaft also carries a spur gear 36 and has a bearing in bracket 37. Spur gear 36 engages a gear 38 on either side of which ratchet teeth 39 and 4-0 are provided.

The said gear 38 is mounted on a shaft 41 having ends secured in members 42 and 43. Rotatably mounted on. shaft t1 are themembers 44c and 45 which are similar in construction and serve as pawls to engage the ratchet teeth 39 and &0. Only one member can engage the teeth at any time. Figs. 7 and 8 illustrate one of the members 4 1, and d6 indicates the engaging projection for the ratchet.

The coil springs 17 and as being oppositely wound, are provided as means for producing tension when the members 4A and 45 are actuated. They are secured to shaft 41 and members 44 and 45 respectively. Both members 44 and 45 are provided with pins 49 that are designed to engage the forked ends of a yoke member 50 that is pivotally connected to an armature 51; the latter being a portion of a solenoid 52.

A shifter 53 is provided with forked wedge shaped ends 54: and 55 respectively, for engaging or disengaging either of the members 44: or 45, by producing a horizontal movement of member 53 through the means provided; a screw 56 and crank 57.

The numerals 58 and 59 respectively indicate shutters that are provided to shut off the view during the operation of changing a street name. The shutters are pivotally mounted at each end and two of their relative ends are provided with extending pivot members, .60 and 61,- which are fitted with meshing spur gears 62 and 63. Pivot 60 is also provided with a tension spring 64: that is secured to the same at one end and to gear 62 at the other end. An arm 65 is also fixed to pivot 60 and from one end of said arm, a flexible cord 66 is continued around pulley 67 to a slidable member 68 having guides 69 and a lower projection '70. A slotted link '71 connects member 68 to arm 72, the latter being secured to the yoke 50 and the former having a pin extending through the slot. A guide arm '73 is provided to serve as a supporting guide for a latch 74 that is pivotally secured in bracket 75 and a spring '7 6 is provided to add ten sion to the latch '74.

trolley pole 88. I also provide a contact arm 89 of suitable material, that is connected to the trolley wire 90. From arm 89 extends arm 89 The object of arms 89 and 89 is to close the switches 86 and 87 respectively, when brought in contact; which operation will, in the former case complete the circuit from the storage battery through wire 91 to solenoid 52 and return through wire 91 Wire 93 extends from the storage battery to switch 87 and continues to solenoid '78, and returns through a return wire 93 A wire 95 connects storage battery to electric bell 83 and from bell 83 I extend a return line 96. The object of this is to produce an alarm after the solenoid '7 8 has attracted the armature and released it. The attraction of the armature produces a contact between projection 80 on armature 79 and wire 96 which sends a current through the bell and returns through wire 93 The bell will continue toring until the connection is broken between projection 80 and wire 96. The air cylinder 81 allows the armature '7 9 to be attracted easily and quickly; at the same time compressing spring 84: and retards its return to hold the connection between 80 and 96 for a specific length of time. The bell rings only when a street is indicated, with special instructions in connection therewith as shown in Fig. 12. Hence the two switches 86 and 87 are both used only when certain streets are indicated. The bell will not ring when street names appear as in Fig. 1.

The web 22 is wound on roll 18 and passes over roll 19 to roll 20 where the same is secured. Through the movement of roll 19, that is actuated by the gear 33 and worm 34:, the web is released from roll 18 and wound on roll 20 at proper times. In effecting this movement the spiral member 31 gradually tightens through the gear connections and spiral member 32 gradually reing up action of roll 9.0.

The worm 34c and gear 23 are actuated on the spring stroke or during the return of the member 4st. The act or" sending a current through the solenoid 52 attracts its armature which, being connected to the yoke 51, will operate the ratchet member 14: and turning movement of the latter will be effected and the spring 47 will be put under tension. When the circuit of the solenoid is broken the tension of the spring 4:7 will turn the gear 38, by reason of the engagement of the projection t6 on said member d4: with the teeth 39' on said gear, the turning movement of which gear transmits movement to the gear 36 which actuates the worm 34c and the gear 33 to move the web; and the spring stroke also returns the yoke 50 and armature 51 to their original positions. The arm 89 is so located that the movement formerly described will take place at a point between two street intersec tions and at which time, the intersecting street ahead of the path of motion, will appear on the web, and be magnified by the glass 77.. p i

I provide the shutter members 58 and 59 to obscure the web movement while a street name is being changed as described. The

leases its tension'which produces the windshutters are operated at the time of the tract-ion of armature 51.

Fig. 11 shows the position or" the shutter operating mechanism at the end of the solenoid stroke, the member 68 being locked and the shutters being closed. when the link 71 is moved to the left it carries with it the member 68 until the raised portion of the arm '73 causes the latch 7 1- to crowd between the lug 70 and the arm '73, the flexibility of the latter permitting this action, so that the latch 7% will permit the lug 70 to pass and engage the same as shown in 11, which closes the shutters and eX- tends the spring 6-1, the member 68 remaining locked until the solenoid releasesits armature, permitting the link 71 to move to the right to a distance equal to the length of the slot therein, thereby-shifting the arm 73 a suflicient distance to the right to withdraw its raised part from the latch '74, which latch '74 is then disengaged from the lug 70 by the spring '76, permitting the sliding member 68 to shift to the right and open the shutters, at or about the time the web is advanced by the pawl and spring mechanism described.

hen the end of a car line is reached pawl. 4 1- is thrown out of engagement by shifting the forked member 53 and member 45 is engaged. The indicator is then ready for a return trip and the web will be wound on roll 18 by a; reverse movement of worm 34: and gear 33. I The reverse movement is produced by the reverse action of member 45 in relation to rotating gear 88, although member 45 is actuated in the same manner that at is actuated.

What I claim as new is:
