CHARLES E. BONINE, OFJ PHILADELPHIA, PENNSYLVANIA, ASSIGNOR -TO THE ELECTRIQ SERVICE SUPPLIES COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORA TION OF NEW JERSEY,-

To all whom it may concern:

Be it known that I, GHA'RLEs E. Bonnie. of Philadelphia, in the county, of Phila delphia and State of Pennsylvania, have invented certain new and useful Improvements in Signs for'Railway-Cars, whereof the following is a specification, reference being had to the accompanying drawings.

My invention relates to new and useful improvements in signs, and more especially that class of signs which are used in connection with railway cars in order to give notice of the prospective stations or streets, although it is obvious from certain aspects of the invention, that the same may be used for other purposes.

The invention has more particular relation to the means for operating an elongated flexible curtain containing a series of names, which curtain may be wound upon one roll and unwound fromthe other, so that the names may be successively displayed.

An object of the invention is to provide a mechanism for operating the rollers on Which the flexible curtain is mounted, which means shall be positive in its action and durable in construction, and wherein either one or the other of the rollers is always. in operative connection with: the operating means. i

The invention consists in certain 'constructions and 'in' certain parts, improvements and combinations, hereinafter more fully specified.

In the drawings which showby way of illustration one embodiment of my inven tion, Figure I, is a partial front view, and a partial vertical sectional View of my improved device. Fig. II, is a sectional view on the line II, II, of Fig. I. Fig. III, is a sectional view on the line III, III, of Fig.

' I. Fig. IV, is a sectional view on the line heavy metal,'which has a flange 4, project- Speeification of Letters Patent.

SIGN FOR RAILWAY-CARS.

and a downwardly projecting portion 8, at

the front of the casing. The bottom piece 6, is provided with similar parts 9, and 10.

An angle piece 11, is secured to the top metal piece 5, of the casing, and spaced from the flange 7, so as to 'form--'a pocket or recess 'for a glass plate 12, forming the back of the casing. A similar angle piece 11, is attached to the bottom metal piece 6,

and forms a pocket for-theibottom (edge of the glass plate 12. Angle-pieces 11, are also attached to'the top and' bottom port-ions of the casing at points adjacent the front thereof, so asto form recesses or pockets for the front glass plate 13.

' The projecting members 8, and 10, extend at some distance from the bottom and top portions, so as'to partially close the front of the casing. These features form no part of the present invention and are, therefore, not claimed herein,

The flexible curtain or sign' 14, is attached at one end-to a roller '15, and at its other end to a roller 16. The rollers 15, and 16,

are journ'a led in the end plates-2, and 3. At

the right hand end of the casing, as viewed extends in a vertical direction, arid-has its I end of the shaft 21, has a collar 24, attached thereto in any suitable way. The hub 20, is locatedbetween the collar 24, and the bearing 22, which prevents endwise movement of the hub on the shaft 21. and holds the gear wheel 19, in mesh with the gear Wheel 18. The roller 16, carries a beveled gear wheel 25, which meshes with a beveled gear wheel 26, also loosely mounted on the shaft 21, and held in mesh with the gear wheel 25, by the bearing 23. The gear wheel 26, carries the hub 27. The shaft 21, may be turned by a hand crank 28.

The shaft 21,-is provided with a longit-udinal groove or recess 29, (see F1g. II), which extends from a point ad acent the hub 27, to a point adjacent the collar 24. Mounted within the groove or recess 29, 1s a pawl 30, which is pivoted at 31, to the shaft 21. The hub 20, of the gearwheel 19, is provided with a recess 32, which is formed with a radial shoulder 33, and a spiral shaped curved surface 34, extendlngfrom the bottom of the recess 32, to and ownedin with, the inner curved surface of the hdb The hub 27, (see Flg. VI has a similar recess 35, which has a radial shoulder 36, and a curved surface 37, simllar to the surface 34. The curved surface 37, how ever, is located on the opposite side of the recess from that of the curved surface 34.

The locking pawl 30, is so constructed that when the end 38, which cooperates with the hub 20, is housed within the recess or groove in the operating shaft 21,the opposite end 39, of the pawl 30, which cooperates with the hub 27 is thrown out of the recess or groove in the operating shaft to more or less extent. When the recess 35, is brought opposite the end 38, of the pawl 30, as shown in Fig. VI, said pawl may be moved outward into the recess, and the face of the pawl will engage the shoulder 36, on the hub 27 and if the shaft 21, is rotated in the direction of the arrow, Fig. VI, it will cause the hub27, and gear 26, to rotate therewith, and thus impart a rotary movement to the roller 16, through the gear 25. When the shaft 21, is rotating in the direction of the arrow in FigJVI, it is also rotating in the direction of the arrow, as shown in Fig. V, relative to the hub 20. This will cause the upper end 38, of the'pawl 30, to move away from the shoulder'33, and the inclined surface 34, will crowd the same back into the recess or groove in the main shaft 21, and said main shaft 21, will rotate freely within the hub 20.

Let us suppose the parts are in the position shown in Figs. V, and VI, and the operating shaft 21, is turned in the opposite direction. The end 39, of the pawl 30, will then be carried along the inclined surface 37, and said end gradually move into the recess or groove in the shaft 21. Inasmuch as the pawl 30, is made in one piece and pivoted at 31, the other end 38, of the pawl will be raised out of the groove or recess in the shaft 21, and will contact with the shoulder 33, formed in the hub 20, and positively lock the hub 20, to the shaft 21, so it will.

be rotated thereby, and through the gear 18, positively rotate the roller 15. Of course, as the roller 15, is rotated, the flexible curtain being wound thereon, will cause the roller 16, to be rotated by the unwinding of the curtain therefrom, and through the gear 25, the hub 27, will loosely rotate. on the shaft 21, and allow' the unwinding of the flexible curtain from the roll-er 16. It will readily be seen, therefore, that I have provided a mechanism whereinby the simple rotation of the operating shaft in one direction or theother, one roller or the other will be locked to the operating shaft, and

caused to rotate therewith.

The flanges 4, of the end plate 3, project sufficiently far to house the operating shaft 21, and a metal plate may be attached to the outer edges of the flanges 4, so as to completely inclose the operating mechanism. The end plates 2, and 3, as clearly shown in Fig. IV, may also be provided with projecting flanges on their inner faces to rcceive'the glass plates 12, and 13.

It is obvious that minor changes in the details of construction may be made, with out departing from the spirit of my inven tion, as set forth in the appended claims.

I claim 1. The combination of sign rollers and a flexible sign mounted thereon; of gears mounted on the shafts of said rollers; a driving shaft extending at right angles to the axes of said rollers, and driving gears carried by said driving shaft and engaging respectively the gears carried by the rollers; means for holding the driving shaft from endwise movement, means for rotating said shaft; a pawl extending longitudinally of the driving shaft and cotiperating with said driving gears, and means whereby said pawl is caused to engage one of the driving gears when said driving shaft is rotated in one direction and for causing said pawl to engage the other gear when said driving shaft is rotated in the opposite direction.
