To all who-m. 'it 'may coin-cm.:
Be it known that l, lowiN A. ALLEN, a citizen ol the Uniti-d Sintes', und a resident oi Galesburg, county of. Kinox, and #State oi illinois, have invented certair' new und usciul improvexnents in an indicator o1' Display Apparatus, of which the following is declared to be a full, clear, and enact description. I
The invention relates to indicator or Adisplay-apparatus and in particular t'o such apparatus having a long ribbon or tape having Iri'atter ln/arlied or printed' thereon, und the invention suelas to provide simple and effective means by which the ribbon or tape may he shifted in different positions'to display or expose the matter printed on the ribbon.
The invention is particularly applicable and is especially designed to be employed as an indicator for -s'treet or railroad cars and the indicator ribbon will bear j the names of the streets or stations passed by. the car.
The invention consists in the features el construction, combinations and erlangt-:ments of parts hereinafter set forth, illustrated in the accompanying drawings and more particularly pointed out in the appended claims. 4 Figure `1 is a sectional view of the end of a car with lny improved indicator applied thereto. Fig. 2 is an end view of the apparatus showing the operating is` a cross section through the apparatus. l Fig. 4 is a longitudinal section, certain parts being broken away. Fig. 5 is a diagrammatic view of the circuits andapparatus for automatically arresting the movement of the indicator ribbon. AThe apparatuspreferably' includes an inclosingbox` like Casiirgvl which may 'be constructed. of wood or light 'sheet metal, and is provided at its iront with' a glazed opening 2 through` which the streets, stations, or other matter upon the indicator ribbon are displayed.
. l The indicator ribbon or tape 3 is arranged within the box or casing and its ends are detachably connected to bobbins or winding rolls 4 mounted respectively in the upper and lower portions of the 'boli or casing 1. The bobbins or Winding rolls '4 are revolublyi mounted and the uppermost roll is preferably arranged to be removed from' the casing in ordcr'that the indicator tape or ribbonnlayhe removed. .For this purpose the the side of the' box. s ition by a spring 7 and .screw 8. By releasing the stud 5 at one end/of the roll (see Fig. 4) is journaled in a block 6 mounted to slide in the cut-away portion at Block 6 is yielding-ly held -in poscrew and removing the top of -thebox, the slide block VGinny be removed and the uppermost Winding roll or hobbin can be removed. Preferably, a pai-r ofdriving rolls 9 and l0 are associated with eafch of the winding rolls or bobbins 4. These pairs of drive rolls engage the ibbon or tape on opposite sides of the opening 2 int e box or casing 1, and these rollsalso serve to guide theribbon or tap' into 'a'position closelyadjacent the 'opening 2 relation therewith.
l oi the gears 11 and 14 to drive the fore,
The drive or guide rolls Quand 10 are journaled in the sides oi tho casing and a'rc prcierably covered with .rubber or other suitable yieldingr uniterial, so that they will maintain a iirin grip upon the tape. The outer 'ends of the shafts 9 upon which the drive rolls 9 are mounted, extend through one side oi the box or casingvv and are provid-ed with gears 11. hy which rnotion is positivelyl imparted to the drive roll 9 ot each pair, the roll 10 oi each pair being driven by friction.'
Stub shafts 12 are jgnirnalefl. in the end of the box or casing and the inner ends of these stub shafts are carried in bracket. 13 (see Fig. 4), 'lhc projecting ends oi the stub shaib on the outer side of the box are provided with gears 14, and inside the box. or casing the stub shafts are provided with friction drive wheels 15' which engage corresponding friction wheels 1G fixed to the ends of the Winding rolls or bobbins 4.
The main drive lshaft 17 is journaled at one end inthe side oi the box and carries a master gear 1.8 which is ariranged in the plane of the gears 11 and 14., .an arn'i 19 swiveled on the shaft 17, carries an idler or coupling gear 20 whiehis always held in mesh with the master gear 18, and which may be shifted to engage either pair tape or ribbon in op posite directions. The ann 19 extends-on both sides of the drive shaft 17 and carries on its-end opposite the gear 20, a weight 21 which serves to eounterbalance the lgear 20. The drive shaft 17 may be driven from anysuitalle source of power and when rotated inthe direetion of arrow shown in Fig. 1, will carry the idle or coupling gear 2O into engagement with the gears 11 and 14 with the upper portion of thecasing so that the drive rolls'9 and 10 will be positively driven to move the tape or ribbon upwardly Ypast the opening 2. Atnthe same time the winding roll or bobbin 4 at the upper end of the case will be driven through the gear 14 and friction gears 1,5 and 16 to take up the ribbon' or tape as it leaves the drive rolls 9 and 10. The speed at which the drive rolls 9 and 10 will move the ribbon will depend of course,
l upon the speed of the drive shaft 17, 'but the speed with which* the tape or ribbon is wound upon the bobbin 4 wuldordinarily, if positively driven-vary in accord ance with the size of the roll of tape on the bobbin, but these rolls are driven through the friction gears 15 and 16, which are so held by the spring 7 that they will slip to compensate for this difference in operation. The' winding rolls will therefore' not tend to pull the tape or ribbon from the grip of the drive rolls 9 and 10, but will merely serve to take up the slack as it les ves. the drive rolls. i
When the drive shaft 17 is'reversed, the arm 19 and idler or connecting gear 20 will be automatically shifted out ofY engagement with the upper set of gears 1l and 14' inte engagement with the lower setas indicated in dotted lines in Fig. 2. By this peculiar arrangement there the power-to. drive the ribbon' may beaoplied to upper portion of one end of o. car 22 and the drive shaft the movement thereof should be controlled' by the movement o the car so that the distance through which 4 the ribbon moves is proportionate lto the travel of the the drive shot'tV While the rolls :it the opposite end are fri-e to permit thc ribbon or tope to be unrollvd therebon nt proper tension.
of the different streets or stations which ore pssed on' the trip can be noted uporl the blank topo in tho imdb either und thereof for shifting it in opposite directions pos-t the opening 2 ond the coupling device will be auf" tornoticolly shifted from the drive and winding rollsat calor at theproprir places. Anrildieetor or. display one end ofthe ribbon tothe drive and winding rolls at v ribbon oil tope for regular use con then he prepared the other ond by the reversal of the drive shsft 17. from this blank, wbich'tivlin placed in the indicating In Fig. .l tho indicator box is shown arranged in`theapparatus will automatihaily announce the stations or streets as desired.4 Il to? any transmit; lscconies. nece ssry to adjust the tape-dr ribbon, this may he effected by shifting the connecting gear 20 to its inoperntive,
l? is positively geared to the axle 23 of the corso that 'its spoed will be' proportional to the speedo 'the eansnl the distance through which the ribbon is moved by the drive rolls t) and 1t) will be directly proportional to the distance to which the cor moves. f
Any suitable loz'm of gearing may be employedV betvveen the car axle `23.0.nd the drive shaft 17. In the form shown, :t sprocket Wheel 24 is mounted n the car axle and is connected to a. companion sprocket Wheel on a cross shaft 2o' Vhy a chin 27. A gear 28 on the cross' shalt :2d engitgos o. worm wheel 29 on a shaft' 30 which extends longitudinally beneath the car, An upright counter-shaft 31 is geared at its lower end to the shaft: 30 by the beveled gears 32and at its upper end to the shntt; 17 by the beveled gears 33. In a similar manner shaft, 30 may he wronged to drive another indicating device at the opposite und of the car. By the arrange ment'dcseribed, it will be seen that' the drive rolls 9 and l() will be positively driven to move the indicator or display ribbon et s speed proportional to the spoed und. distnnce through which the csr moves while the winding rolls Ll.- will be operated td take up the slack. M ore-4 over, fbe'direction of movement, of the ribbon will he automatically reversed when the direction of the travel of thel cari's reversed at the end of its route and at the same time the coupling device will he shifted automat- Means are preferably ribbon or tape from being detached from either of the rollers or bobbins. For this purpose, a. pair of Contact strips 36 and 37 tn'e associated with each of the Wind` other In` Fig. 8 the contacts 36 und 37 at the npper end of the box are shown 21s having been brought the upper winding roll or bobbin.
