To all whom it may concern:

Be it known that I, FRANK P. M. \izn,ojf

4 Newark, in the county of Essex and State of NewJersey, have invented certain new.-

and useful Improvements in Signs for Railway-Cars, '&c. whereof the following a specification, reference being had' to the aceompanying drawings.

My invention relates to that class of signs in which an elongated flexible curtain eontaming a serles of names marked thereon, is mounted upon a pair of rollers,, by whose "rotation, in either direction, the curtain may bewound upon one roller, and unwound from the other, and the names may be suecessively displayed at a region intermediate between said rollers.

\Vhile the mostobvious application thereof is for use uponrailway'cars, in order to give notice of the approach of the respective stations or streets, and while I am about to describe an embodiment 'of the invention anism; to protect the curtain itself from deterioration by dust, moisture and'the like, whileailordingieasy access to the actuating and con rolling meehanismyandto provide means whereby the curtain, its casing and its actuating mechanism maybe interchange-- ably mounted within a suitable inc-losing receptacle, adapted to be readily applied to the required portion of a car structure In the accompanying drawings, Figure T, represents a to or'plau view of the int-losing receptacle, an Fig.'II, a rear view thereof,-

thescale of these fi ures beim 'one-half that; of the succeeding ures. g. III, represents a vertical longitudmalsection through the device and its rece )tacle on the line I] I,

III, of Fig. I'. Fig.1 is a transverse vertical section on the line IV-'IV of Figs. I and III, the direction ofview beingnd'if noted by thearrow at the section line; Fig.

- V is a transverse vertical section on the line V V ofF igQ III, the direction of: view beline'; Fig. VI, is a partial sectionalview,

showing the upper edge of one of the end plates of the casing. Figs. VII, and VIII,

relate to modified forms of' the actuating mechanism, the same being represented-1n each instance 'in vertical section, and upon a line corresponding to that of the section V IV, IV, in relation to the general structure.

I .will first describe the external inclosing receptacle adapted to contain the casing proper, which latter it will be understood is of an elongated rectangular form, adapted as will be hereinafter stated, to slide longitudinally within said receptacle.

The "receptacle is constructed of sheet metal, and comprises an elongated box 1, whose, front face and ends are of substantially rectangular form, its top, bottom and back being extended rearwardly in a double incline, as shown in the' plan 'viewiof Fig. I,

so as to'leave a clear space or chamber in the rear of the' casing proper, which is indicated by the dotted lines at 20, in Fig. I, The

front face of the receptacle is extended in a flange 3, IM'QJQCtllIg beyond the top and bottom andends, and affording a convenient- 7 means for securing the receptacle within an opening in a panel or wall of the car. A, rectangular opening 11, (sec dotted lines in- Fig. II),is formed in the front of the receptacle, opposite to that portion of the curtain which-is between the rollers,-in order to display the name upon said curtain, An

aperture 2, in the-top of the receptacle above the rearwardly extending chamber permits the insertion of an electric lightbul-b, or the employmei'it ofa lamp with chimney (conventionally indicated by. the dotted circle at 4), whereby the sign nay be. illuminated from the rear.

- one end of tlie casing is formed by means of a door 5, ghingedto the front at (3,a see- 'ond'door 7, being hinged to' the door 5, at

8, and closing against the strip 9, to which it may be detachably secured by screws or 4 otherwise. A slot 10, is forinedixr' the door- 7, to re,ceive the shaft-of the actuating crank (35, which will be hereafter described. A

portion 'of'the' rear wall adjacent, to saiddoor 7, is; also formed-bymeans of adoor 12, hinged to thetop, at 13, and having VThe casing proper 20, which" comprises the housing-for-t-he actuating and control spring retainin-gplips 14, mounted upon the V 'bottom'of the receptacle, whereby the dooir .12, is retained in closed position. 5 ing indicated by the arrow a't,the section tion' the gl ss through the plates'21,

The top and bottom plates, 23, and 24, respective y, are of li hter metal and arefsecured to horizonta flanges 25, upon said plates. A pair ing vertical flanges or ribs 26, (see Figs. near each vertical lates 21-, and 22, and form grooves to 'hol in posiplates 27, and 28', which con- .stitute' respectively the.

the casing 20. Inwardly and 30, are arranged near to each longi-j tudinal edge of the top and'bott'om plates 22, and 23,-anda-port1onof the edges beyond .said ribs is bent at main surface of the 'plate, so as to form inwardly extending flanges 31, and 32, at a geof the end short distance from said ribs 29, and 30,.

thus providing grooves whichlreceive the upper and lowerv edges of the glass plates 27, and 28. Packing strips 33, of felt are in-' serted in the'several grooves so as to emrendering the casing practically dust-proof and weather tight. C The flexible curtain 34, is mounted upon a pair of horizontal rollers 35, and36, whose journals 37, and 38,'r espect1vely protrude The shaft 37, of the upper roller 35, carries at one ,end a bevel gear 39, rigidly secured thereto, said gear engaging with. a corresponding bevel gear 40. The shaft- 38," of the lower roller 36, is similarly provided with a bevel gear 41, engaging with the corresponding bevel gear 42. The upper bevel gear 40, is provided with a rigidly attached and downwardly projecting sleeve, or hub 46, whose lower end is formed into a series of teeth 48, having inclined backs, so as to constitute one member of a clutch. Said clutchdxub is-journalcd in a brncket'4-7, extending laterally from the plate 22, the por what larger diameter than the journal portion, so as to resist upward thrust. The lower bevel gear 42,, is provided with a rigidly attached and upwardly extending sleeve or hub 49, whose upper end is formed into a series of teeth 50, with inclined backs, said teeth facing in a direction opposite to i thoseof the other clutch-hub. The gear' protection or moisture, is rectangular and ed'to slide longitudinally into the 1 1, through theopening which is gr'ovidedwith the folding doors- 5, and 7.

The'length and inclinationof the-slot 5.9,

i j 5 is 50- related to the'de th. of the clu'tcli teeth andthe inclination o the backs thereof, as

to act- .in correspondencewith the disengaglng movement 'of the teeth and to prolong the axialf iirection of saidmovernnt after a '10' d sen" agement has taken place, and -un til' comp ete' engagement-of the other set of teethfihas been efiected. Thus, assuming that the parts-'are in the positi'oh'shownfin Fi III, (that is to say, that the lower clutedi 1.5 member 54',' is in full'engagement with the clutcfh-liub 49,.while the upper clutch-monk her 55, is completely disengaged from the upper clutch-hub 46; if now the shaft 45, be, rotated from left to right, the teeth of the lower clutch-member will rideup on the x backs of the teeth 50,2of the'lower clutchhub,'and simultaneously with this action. the 'pin 60, -willf' ride u the wall -of the slot -59. i'The longitudina I movement-of the shaft- 45,,thusj occasioned, will bring the teeth upon f the upper cl-utch+member 55, into contact with the teeth 48, upon the upper-clutch member 46, butsaid I. teeth would not,fbythis movement alone, be thrown entirely home into the teeth oftheu p'er clutch-hub, since the-disengagement of the lower one occurs before-they have-reached Tsuch ex-,

- treme position. The slot 59, however, is prolonged to such an-extent that the continued 85;: ovement of theshaft-r'i, from left to right causes'the pin 60,-tor-ide upward to the fulllength voflthe slot, and the additional axial movement f thus effected, throws the teeth of. the upper clutch-member 55, home into the teeth 48, of the uppercluteh-hub. \Vhen the pin-60,*hasreached the upper extremity e slot59, it-rests within the pocket at 'glown the slot under the efieet of gravity. It will thus'be seen that rotativemovemerit of the hand-crank 65, in one direction will transmit movement from one clutchmember tothe operative gearing of one sign roller, and that rotation of said crank in Qthe opposite direction will firsteauseilisengementof. theclutch-member, whicli-ihas theretofore been operative, and will acause that the driving gearing of the-other sign roller will then be actuated. In'eitheij case, however, the-roller, which forthe time being is idle, would, if not-controlled, tend to run free, and hence might, by over-running, bring about a loose conditio'n of the flexible sign. To rev'ent this, I en'iploy a braking device, preierably arranged atthe opposite end of the casing from the driving system, said braking device comprising a pair of elastic strips 70, and 71', having curved surfaces 72, 73, 74. and 75, at their respective ends,

engagement offthe other clutch member, so"

which surfaces are adapted to einln'arehubs 76, and 77, rigidly mounted upon the protrudingends of the roller shafts 37, and 3S. Eaid strips 70, and. T1, are-preferably made of oak wood, which hassufljcient elasticity for the. purpose, and affords :the desired frictional contact. .In order to adjustxthe hubs, I provide a screw bolt and nut 78, \vherby they may be drawn together with the desired degree of pressure.

It will be noted that the actuating system for the rollers, and also thebraking devices therefor, are. mounted externally to the casing proper, so that they are readily accessiing,'etc. This feature I find to be very desirable in this class of devices, as there is no necessity for, -opening the 'incl'osure of the sign, the life of which is greatly prolonged by complete and efficient protection, especially as against dust.

1 of the actuating mechanism, the only difference, however, consisting in the substitution of an ordinary spur gear 80, for the bevel gear 56, just described, and the actuavertical counter-shaft 82, and provided with a crank handle 83, which, in this instance with, and the co sliding shaf unter-shaft for driving the 5,":1re omitted. In this inclutch' inembersfifi, and 97, is similar to that "-ju'st'described, but the vertical shaft 98, 4 (which corresponds-to the shaft 45, before descrihed),f-is directly. attached to the crank end thereof. part-sin this apparatus is that shown in'Fig. VIII, where by reason of gravity, the shaft r98,-and"i ts handle 99,al\vays tend to maintain thelower clutch-member 97, in contact pressure of said braking strips upon the In F ig. VII, I have shown a'inodification tionofsaid'gear- 80, by .means of afcorr'esponding spur. gear 81, mounted upon the fication of the.= device, in whichthe slotted hub 57, and pin intended to coiiperate therehandle -99,'which is arranged at the lower The normal position-of the .ble'for purposes of adjustment, repair, oilit-will be noted, extends verticallydown be- Ylow'the casing, instead of horizontally to' the rearthereof.

Disengagementof the '15 nat'ural tendency o'werclu tch-memberhaving occurred, I the on the part of the operator, is to prolong-the upward movement, and
