SPECIFICATION forming part of Letters Patent No. 388,058, dated August 21, 1888.

Application iled January 3, 1F88.

To @ZZ whom, z' may concern:

Beit known that l, MARQUIS L. MANN, a citizen of the United States, and a resident ol' Brooklyn, in the county of Ki ng and State of IXew York, have invented certain new and useful Improvementsin Station-Indicators, of which the following is a specification.

My invention relates to station or street indicators for railroad-cars or other vehieles,and especially that class thereof in which an apron containing the naines of the stations is alten nately wound on and off either of two rollers for successively bringing said names into view.

The novel features of my invention are here inafter fully described, and illustrated in the accompanying drawings, in whieh- Figure l represents a vertical longitudinal section looking at the face ofthe apron. Fig. 2 represents a Vertical erosssection on the line .fr fr, Fig. l. Fig. f3 represents a like section on the line g/ o, Fig. l. Figs. 4 and 5 represent detail views of parts.

Similar letters indicate similar parts.

The letterA indicates a hex or case of wood or other suitable material, in which are secured standards, forming hearings for the shafts of two rollers, C, carrying the apron D. The face of this apron is marked with the naines of the stations, streets, or other places to he indicated, and the case A is provided with a sightopening, a, Fig. 2, through which said naines are exposed in succession as the apron is wound on and off either of the rollers.

For the purpose of producing the required motions of the apronrollers C, each of the roller-shafts is provided with a fixed spurwheel, F, and a loose cog-wheel, G, which latter is provided on one side with a spur, b, for the spur-wheel, and thus transmitting thereto the power from a driving-wheel, H, the latter being also a cog-wheel and gearing with both said loose or transmitting wheels. In practice one of the transniittiiig-wheels, G, is set to eugage the proper spnr-\vheel, F, and the other to clear or disengnge the corresponding wheel, as shown in Fig. l, these positions thereof heing reversed when it is desired to change the direction of the apron-rollers and apron. To shift the transmittiiig-wheels G, I elnploya lever, I, and a side rod, J, having a forked end to engage said lever, the latter having its fnlerum in a bracket, c, secured to one of the Serial No. 959.631. (No nimh-l.)

standards l, and its ends heilig constructed to engage the hnhs ol' the transmitting wheels. The slidevrod .l extends outward through one end ofthe case A, and may he provided with a latch to hold it in position.

The drivingwheel .it is fixed on its shaft, and on said shaft are also fixed two ratchet- Wheels, l, (see Fig. 4,) the teeth of which project in opposite directions, and which are inclosed in a circular case, L, having suitable openings to admit to said wheels spi ingpawls N, which serve to ini part motion thereto, said pawls N being pivoted to a swinging arm or lever, O, at points opposite to the ratchet- Wheels l, respectively, so that either of the pawls may engage one of said wheels. The pawlarin O is hung on said shaft ofthe driving-wheel H, and an operating-cord, d, is connected to one end thereof, while its other end is provided with a weight, c.

"When the pawl-arin O is in the position shown in Fig. 2, a pulling of the cord d has the effect of swinging said arrn in the direction indieated by the arrow, and by this means one of the pawls N is made to engage the proper ratchet-Wheel and turn the snine,together with the driving-wheel l-l, in one direction, while when the pawi-arin is in the position shown loy dotted lines in said figure the other pawl is made to engage its ratchet-wheel, and the motion ofthe parts is reversed, so that, according to the position of said arm, the motion of the apron-rollers is in one or the other direction. Vhen either of the pawls N is in operation, the other pawl simply rides upon the hack of the case L without affecting the parts.

For the pn rpose of changing the position of the pawl-arni O, i employ a reversing-lever, l?, (see Fig. 3,) to which is secured a fork, Q, engaging a stud, i, of said arm in such a inanner that by swinging said lever to the position shown, respectively, by full lines and dotted lines in Fig. 3 the desired adjnstmentof the pawl-arin may be effected. Stops R are se cured to one end of the case A.,to regulate the position of the reversing-lever, and the latter is perforated to receive a holt, m, for holding it in either position. The fork Q has a shank, j", which is fitted in an oscillating guide, g, to slide therein when the reversing-lever is being set.

in order to announce the shifting of the IOO apron D, I employ an alarm-bell, S, the harnmer-lever T of which is arranged in the path of a lever, U, to one end of which is connected a spring, h, and to the other end an operatingcord, 7c, which in practice is united to the other eord,d,in such a manner that the bell is sounded as often as the shifting mechanism is actuated.

In order to permit the apron-rollers to be turned independently of the shifting mechanism, one end of both roller-shafts may be squared, as shown in Fig. l, to receive a suitable key or Wrench.

A brake, V, may also be used to retard the motion of the apron-rollers.

Vhat I claim as new, and desire to secure by Letters Patent, is`- l. In a station-indicator, the combination, with an apron and apron-rollers, ofthe fixed spur- Wheels F and loose eogwheels G, both mounted on the shafts of said rollers, each of said loose wheels having a spur to engage the proper spur-Wheel, the shifting-lever l, engaging the loose cog-Wheels, the slide-rod J, engaging the shiftinglever, the driving-shaft H, gearing with both loose wheels, and a means for imparting an intermittent motion to the driving-Wheel, the Whole adapted to operate substantially as herein described.

2. In a station-indicator, the combination, with an apron and apron-rollers, of the driving-wheel H, arranged to impart motion to said rollers, the two ratchet-wheels K, having reversed teeth, the pawlarm O, carrying pavvls for engaging said ratchet-Wheels, respectively, the ease L, inelosing the ratchet- Wheels and having openings to receive said pawls, and a means for imparting a vibrating motion to said arm, t-he Whole adapted to operate substantially as herein described.

3. In a station -indieat0r, the combination, with an apron and apron-rollers, of the drivingwheel H, the ratchet-Wheels K, having reversed teeth, the paWl-arm O, and paWls for` engaging the ratchet-Wheels, respectively, the Whole inclosingcase L, the reversing-lever P, having a fork, Q, to engage the paWl-arm,and the stops R,for regulating the position of the reversing-lever, the Whole adapted to operate substantially as herein described.
