ARTHURSCHIMMEL, or EVANSVILLE, INDIANA. STREET-INDICATOR.

Specificationof Letters Patent.

Patented Oct. 16, 1996.

To all whom at may concern;

Be it known that I, ARTHUR SCHIMMEL, a citizen of the Evansville, in the county of Vanderburg, State of Indiana, have invented certain new and useful Improvements in Street-Indicators, of which the following is a specification, reference being nying drawings.

This inventionrelates to a street-indicator, Y

and particularly to an apparatus of that character embodying a web carried upon oppositely-disposed spools and wound from one to p the other thereof.

' spool and means The invention has for an object toprovide a novel and improved construction and arrangement of driving means for rotating one of the spools to draw the .web from the 0 posite spool, together with meansifor shifting this driving means to permit rewinding of the for effecting an intermittent release of the spools and Web carried thereby.

Other and of the invention will be hereinafter fully set forth and the novel features thereof defined by the appended claims. In the drawings, Figure 1 is a central crosssection through the indicator. Fig. 2 is an end view thereof looking from the right of Fig. 1. Fig. 3 is a vertical section on line 3 3, Fig. 1. Fig. 4 is a detail perspective of the casing opposite the sight-openin for the web, and Fig. 5 is a similar view of the means for lcolilinecting the web to the hub of the spool or ro I a Like numerals of reference indicate like parts in the several figures of the drawings.

The numeral 1 designates a supporting frame or casting of any desired character provided'at its upper and lower portion with elongated bearing-boxes 2, adapted to ,receive a journal or shaft 3, extending inward from each of the web-spools 4 and held in proper position by means of a collar 5 upon the innerend of the shaft 3. ried by the shaft consist of the central hub 6 provided with a slot or recess 7, extending longitudinally thereof and in which the metallicstrip 8, carried by the end of the web 9,

cured to the opposite ends of this hub are the' spool-heads 10, the outer one of which is held in position by the washer 11, seated upon a squared United States, residing at.

had therein to the accompa further objects and advantages- .30, adapted The spools car' ortion of the shaft 3, and a clamp-nut 12, t readed to the end of the shaft beyond said squared portion. The inner head is provided with apertures 13 therein, disposed at opposite points and adapted to engage points or projections 14,

carried by the gear 15, secured upon the shaft 3 of the lower spool, and the gear 16, secured upon the shaft 3 of the upper spool. The construction of each of the spools is similar, with the exception that the driving-gear 16 upon the upper-spool shaft 3 is provided with an inward projection or lug 17 to cooperate with a latch or holding-pawl 18, which is pivotally mounted at 19 and normally held in engagement with the lug 17 by a spring 20.

For the purpose of ermitting the intermittent movement of the apparatus an electromagnet 21 is disposed pawl and connected, by means of wires 22, with, a suitable switch 23 and battery or other source of power 24, so thatu' on the closing of the switch the magnet Wil be enabove the holding ergized and the pawl lifted to ermit a rotation of the gear 16, which t en again engages the pawl, as circuit is onlymomentarily made by the switch.

Any desired form of motor may be used for the purpose of driving. or rotating these spools; but for the purpose of illustration I have shown an electric motor 25, mounted upon the carriage 26, which isdis posed to slide or reciprocate within the ways 27, carried by the casting 1.. The shaft 28 of this motor extends through a slot 29 in the castingl and is provided withla, driving-pinion to be shiftedupward into engagement with the gear 16 or downward into contact with the intermediate pinion 31,

which is carried by the stub-shaft 32 and meshes with the gear-15 of the lower spool. This latter position of gearing is that -normally used to rotate the Web for the purpose of exhibiting the streets or stations named thereon. In order to prevent a slack in the --movement of the web, a friction-wheel 33 is secured to the stub-shaft 32 and adapted to contact Withfi. friction-brake 34, adjustably mounted in a lug 35 by means of a screw 36 asshown in Figs. 1 and 2.

The preferable construction ofmotor is a -t-'slow electric motorv to which current is carried by means of the wires 37 connected therewith and with any suitable source of ,power, as indicated at 38, which in the'case teases an eiectric-=-car may be -taken-in shunt from the motive power or fromJsto-rage-orw other batteries thereon. I p

The motor may be shiftedii j-Pways by any desired ccnnectio'n' efor since, by means of the lever .39, pivoted at t!) and provided ivith. crank member.-.41, .connected by a pivoted link-42 with the'carriage 26 of the motor. This lever is adaptedto be sena cured any. desired. position by'means of the 43 carried therebyand extending rethrough, so as to engage in any one of a s ies of apertures i li, cz-irri-ed by a portion 45 of the .castingsaid pins being under the ten- ;5 sion of the spring 46, passin beneath the jijheeper 47 on the lever. It wi lbe seen that latch 43 when withdrawn from the aperwill release and permit a movement of. the lever to shift the motor and its ear into to engagement with either'of the spool-driving. connections.

The parts so far described may be in'olosed inany desired construction of frame or casing--for instance, as shownat 48- the front thereof being provided with a suitably slated aperture 49, across'which the Web 9 irom the spoois extends, andfor the pur ose of guiding this web in its assage the ho der 5G is -provided and prefdrably formed of c sheet material, as shown at 'Fig. '4. This holderis mounted by means of lugs 51, comprisingflanges at opposite sides thereof, which engage the tracks or ways 52, carried by the inner face of the casing, and the edges 5 of'the hold-er over whichthe web passes are rounded by curving back a portion eof, as shown at 53, so as to prevent i'n Ury or cutting of the web. This -mountii1g also permits the holder to be readily slipped from 40 engagement with its retaining-ways and removed with the web and spools, upon which the same wound when it is desired to insertanother or different web in the indicatorfor instance, when the route of travel of 45 the car is. changed. It will also be'seen that these spools may be directly withdrawn from their driving-shaft by simply removing the-thumb-nuts fi'om the end thereof.

In; theopelation of the invention it will be 5o seen'that' the motor and its gear are shifted theintermediate position (shown in Fig. i) into engagement with the lower drivinggear, so as to impart a slow motion to the iower spool when circuit is successively com- 51 pleted to lift the'holding-pawl engagin the driviiig-gear of the upper spool, Whic at this time remains idle. When the route has w been completed and it is desired to reverse or rewind the web, the motor is shifted into enrent with the upper spool and the hold ing-pswl by its magnet out of the path of its lug, so that the Web may be rewound at a greater speed. The means'for mounting the. motor to reciprocate "or triavel in a 6:5 straight path causes this-gears todirectlv ap preach-each other in meshing andobviates the difficulties present in a swinging "struc ture, while it embodies the utmost simplicity carried thereby, a motorcarriage slidingly mounted intermediate of the spools, drivinggears carried by said spools, a motor 'upcn said carriage provided with a gear disposed to travel ina straight line relative to the axis of the spool-gears to drive either thereof, and means for shifting said carriage.
