I will now describe the interior mechanism which is contained within the casing 1.

3 indicates a base plate which is located within the casing 1 and from which extends u wardly standard plates 4;, 5 and 6. The p ates 4t. 5 and 6 are connected together in proximity to their upper ends by tie bolts 7 and 8.

9 and 10 are shafts journalled in plates 4 and 5 and located vertically one above the other.

11 and 12 are flanged spools which. are secured to the shafts 9 and 10 and on which is wound a fabric band 13 which is adapted to be fed by mechanism, which I will hereinafter describe from one spool to the other.

Upon the band 13 is inscribed the names of the streets such as indicated at 14, the names oi the streets being spaced apart so that the street name appears opposite the exhibiting orifice 2 at each movement of the band 13.

In order that suflicient tension may be exerted on the band 13 I provide pressure rollers 15 mounted on spindles 16 journalled in arms 17 and 18 the upper arms being swung upon one of the bolts 8 and the lower arms on bolt 8 as indicated in Fig. i. The rollers bear upon the upper surface of. the band as it. is wound on and off the spools 11 and 12.

19 and 19* are rollers carried between the plates 4 and 5 and around which the band 13 passes so that it extends vertically at the inside of the exhibiting orifice 2.

53 is a gear securedto the short shaft 1-5. 33* is a stub shaft carried hythe plate 33" is a pinion tormed integral with the gear 30 and meshingwith the 28 is a pinion also mounted on the 56 is a level which is hingedl i'nounted at the lever 56 is provided with a :torlc 53 one 59 isa standai d in which the short shaft 45isjournalled, the opposite end being journalled in the plate 35 is afstub shaft carriedh the standard 37* and "formed intra rral and mounted uptnnthe sliailt 35" the gear 37* meshing with the pinion 28 and the pinion 37 meshing with the gear 53. By this means the shaft 45 is driven in the direction of arrow (see Fig. 2) carrying the finger 51 oil with the high end ol the semicircular face of the cam 52.

The lever 56 is sprinp held in its normal position by a spiral spring GOeXtending between the standard 59 and the lever 56.

The arm 39 is provided with an inwardly extending tongue 61 The tongue 61 extends between the semi-circular flange 50 and the plate 5. it The flange 50 is provided with an edge groove 50 into which the end. of the tongue 61 extends. *VVhen the short shaft 45 is rotated in the direction of arrow the finger 51 is carried. off the end of the cam 52 so as to strike the tongue 61 thereby forcing thesleeve 457 longitudinally and swing ing the lever 56 on its hinged center 57 against the pressure of the spring 60 toward the plate 5. The tongue 61 is heldin the groove 5O during: half a revolution of the shaft 45 and by further rotation of the flange 50 allows the arm 39 to swing outm :d on its hinge 40, as the tongue 61 passes out of engagement with the grooved portion 50*oit the flange 50,01 in other words, such operation carries the semi-circular flange 50 out oi engagement with the inwardly extending portion or tonjrue 61 of the arm 39. Such arm 39 being then swung outward by means of the tension spring 44.

ltwill of course be understood that the opposite direction.

In order'that there may be alternately a direct drive between the sprocket gears 20 and 21, and the hafts sand 10 I have provided toothed wheels 62 and 63 which are mounted upon the shafts 9 and 10 and are connected to be integralwiththe spools 11 and 12.

64: and 65 are arms each provided with a perforation 65 .66 is a hook preferably tornied' or wire which is bent concentrically with the corresponding wheel 62 or 63, one cnd oi the wire being" bent inward radially of the wheel at 67 toengagethe teeth of such wheel the opposite end being bent'at right angles 68 so asto pass through the perttn'ations65 and through an orifice 69 lifllljlefl 111 each gear 20 and 21 the extreme I end of the wire being bent radially and then inward to pass through a perforation 65 forming a crank end.

It will be noted on referring to Fig. 8 that the end of the portion 68 being bent into crank as the sprocket wheel 21 is rotated in a forward direction the lower hook thrown into engagement with the tooth wheel 63 and the upper hook 65 out of en gagenieni; with the tooth wheel 62 thereby forming a driving connection for rotating the band 13 in a downward direction or direction indicated by arrow in Fig. 3. When the sprocket wheel 21 is rotated in the opposite direction the upper hook 65 is thrown into engagement with the toothed wheel 62 thus rotating the spool 20 and allowing the spool 21 to idle or run free.

71 is a starting motor, the main shaft 72 of which is provided with an arm 73 having an out turned portion 741.

75 is a vibrator provided with the usual coils 76 and armature 77. 78 is a curved arm which is secured at one end of the armature 77 and provided at its opposite or free end with an insulated latching piece 79.

80 is a shaft which is journalled in a bracket 81 and upon which is mounted. a wheel 82. The wheel 82 is spring held from rotation by a tension spring 82 (see Fig. 3).

83 is a catch the upper face of which is curved so as to radially slip by the insulated piece 79 in its upward movement and engage behind such catch piece.

8 1 is a contact finger also carried by the wheel 82. 85 is an arm extending radially from the shaft 80 and bearing upon the spring support 86 in its normal position.

87 and 88 are the terminals of the motor 71. 89 is a wire leading from the terminal 88. 90 is a battery. 91 is a wire leading from the terminal 87 to one terminal of the battery 90.

92 is a push button switch provided with stationary contacts 93 and 94 and a bridging contact 95. 96 is a wire leading to the other terminal of the battery 90 to the switch contact 94. The wire 89 leading from the terminal 88 extends to the other stationary contact of the push button switch.

The band 13 opposite each street name is provided with a metallic contact piece such as indicated at 97., and 98 is an insulating block carried by the plate 1.

99 and 100 are'contacts carried by the block 98 and spaced apart, such contacts being bridged by the contact piece 97 as it passes thereover during the revolution of the band 13.

101 is a battery. 102 is a wire leading from one terminal of the battery 101 to the contact 99. '103 is a wire leading from the other contact 100 to one terminal of the vibrator 75. p

104 is a wire leading from the other terminal of the vibrator'to the opposite terminal of the battery 101. 105 is a pin extending upwardly from the base plate 3 and. on which is swung an arm 106 provided with a metal contact 107. The opposite end of the arm 106 is provided with a fork 108 into which extends a pin 109 such pin being formed integral with the wire l2.-

110 and 111 are opposing contacts between which the contact piece 107 is designed to swing to form a bridging connection between the contacts 110 and 111.

112 is a wire extending from the contact 110 and tapped into the wire 103 at its opposite end. 113 is a wire extending from the contact 111 and tapped into the wire 102 at its opposite end.

Having described the principal parts embodied in my invention I will now briefly describe the operation of the same.

As the car is travelling towards the next street intersection of the route the conductor presses the button 92 closing the circuit of the battery 90 by bridging the contacts 93 and 94:. By'this means the motor 71 is ener gized revolving in the direction of arrow, carrying the out turned portion 7 1 of the arm 73 rapidly against the spring supported arm 85.

By this means the spring support of the arm 85 is momentarily depressed by the downward pressure upon the arm 85. Since the arm 85 is released by reason of the out turned portion 7 1 of the arm 73 passing downward beyond such arm the arm 85 is thrown upward rotating the shaft 80 and the wheel 82. By this operation the catch piece 83 is carried upward in the direction of arrow so as to'spring past and beneath the insulating latching piece 79.

By this movement the'contact finger 84 is carried between the stationary contacts 8 1 and 84. The contacts'84 and 84 form the terminal of the main motor circuit. such circuit being formed by the wire 113 leading i from the contact 84c to one of the terminals of the motor 23, a wire 114 leading from the contact plate 84eto the battery 115 and a wire 116 leading from the opposite terminal of the battery to the other terminal of the motor 23.

When this circuit is complete the motor.

sleeve 36 is feather keyed upon the shat-"n33 As each contact 97 comes into bridging posi tion with the contacts 99 and 100 the circuit of the vibrator 75 is closedfthrough the wire 103 leading to one terminal of the vibrator,

-wire 104; leading from one terminal of the battery 101 and wire 102 to the other ter* minal 99.

As the vibrator operates the insulated con tact 7 9 is moved out of engagementwith the latching contact 83 the spring 82* pulling thewheel back to its normal position carrying the contact 84 out of engagement with the stationary contacts 8% andv 841 thereby breaking the main motor circuit and stopping the movement of the band 13. This operation is repeated at every street inter section. I I

As the finger 51 travels up the camway 52 the tongue 61 engagesthe groove 50* of the flange 50 controlling the movement of the arm Assoon asthe tongue 61 passes out of the groove 50 the arm 39 is carried. by a quick movement away from the plate 5 and the pinion 34* into engagement with the gear 32. I

As soon as the finger 51 passes over the endo'f the camway 52 it strikes the upwardly extending finger 61 so. as to carry the arm 39 inward towards the plate 5' and the pinion 3 1into the reversing position, simultaiicously with this movement the wire 42 is pulled by the arm 39 swinging the arm 106 so as to carry the contact 107 between the contacts 110 and 111 to momentarily close the vibrator circuit thereby. raising the insulated latch piece TQtreeing'the latching finger 83 so as to break the main motor circuit. WVhen the band 13 arrives at the opposite end of its movement the arm 39 is again released and carried out by the spring 4 1. I i i I This movement swings the contact 107 in the opposite direction swinging the contacts 110 and 111 to again close the vibrator circuit and breakthe main motor circuit.

From this description it will be seen that I have devised a street indicator which may be readily controlled by means of a push button operated by the conductor so thatit will indicate the streetsotE a route successivelyand in which the band carrying themdicatin street names will return to its normal position automatically atthe end or the routes. 1 I
