'This invention 4relates' changeable y ex ibito'r'sand particularly relates tojsign' itors for use upon vehrc'lestovfurmshvariable data as to the route of the vehicle', orother desiredV information.

. {'tisjan object or' the invention to mount a4 v exhibitor interiorly adjacent, 'to a ve hiclewindow or windshield, sov that thel ex? hibited' sign may be readily read' through the'gfl'ass."

. nbtherobject 'is topi-Ovide' an exhibitor fora sign, comprising av plurality'of characters, and to provide a simple and compact mechanism for independently changing each .of said., characters: f

A"furtherobject is 'to yprovide a changeable sign exhibitor, comprising a pluralityV of Webs, adapted to travel within a 'casing across a suitable sign opening, and mounted upon drums separately actuable, and arranged in coaxial sets. A Still another object vis topi-Ovide a mechanismof the described character with acommon means for restraining a plurality of drums Y coaxially mounted from accidental turning. i

A still further object is to provvide a sign exhibitor of the described character, having its parts disposed within a casing, and hav-` ing actuating members vfor the separate character-bearing webs projecting from said These and various other objects are fat?" tained by the construction hereinafter de scribed, and-illustrated in the accompanying i, hibitor with the supporting plate thereof,

partly broken away. y Fig. 2 is a section upon the line 2 7-2 of Fig. 1.

v Fig. 3 is a vertical sectional'view of the `same taken upon the line 3--3 of Fig. 1, and

disclosing the exhibitor in its position of use withrelation to a vehicle window.y

Fig. 4 is a perspective view of the drums Aor sleeves forming a mounting, in the im` proved sign, for a character bearing web. lIn rthese views, the reference character 1 designates the glass of a vehicle window or windshield, and 2, the frame thereof.l ,y

The casing `of,v the improved exhibitor comprises` a supporting plateB adapted to be attached to the frame 2 by screws or the like `3a and a coverv member 4, detachably connected to said plate', and carrying the plan view thereof, partly iny mech-:innerer 'the @gin-bitch said para and vcoverf l member are sheet-metal construction.: y l l s 'Said plate is formedwith a row of rec# .tangulartsightlopenings'or windows 5", with* which are registered webs 6, mounted within the'4 casingifor independent vertical' travel, each webv 'bearin'ga series of. suitable letters," numbers or otherbharacters,'whichllmay be',

variably 1 combined through"` v relative 'adjust-vv n ment ofthe webs to formselective'signs. n

,The Webs- 6 are' anp-taiY at `their upper" ends, to' ben secured to fand'wound `upon almed. drums or .sleeves 7, 'and thelower f vendscf said "webs arey similarlysecuredjto v anda'dapted to wind Vupon `ah'ned ,sleeves 7",

The sleeves 7 andf7'd are respectivelyloosely `mountedupon parallel shafts 8 and`8, oc-

cupying respectively the upper and lower portions of the cover member 4, and supportporting plate 3. I

Upon one endof'each sleeve 7 and 7,

`there is mounted fast a knurled actuatingk lwheel 10, and the upper andlower portions of the cover member are slotted as indicatedend thereof, a coiled springis compressed ed by suitable brackets 9 carried by the sup-l A f f between the brackets .9, mounting said'end,

and the sleeve 7 or 7?,.'adjacent to said f bracket. `The expansive effort of each i spring 1Q is transmitted through the entire series of sleeves" 7 or TfL carried by the shaft mounting saidV spring, frictionally restraining all of said sleevesfrom accidental'turn-V 'l f ing. e f

As a `preferred means' for `detachably mounting the cover member`4`oflthe casing`r` upon the supporting plate 3, the upper edge ofsaidv cover member is integrally formed ywith a'pluralityfof'spacedupturned tongues j 13, which are engageable in slits 14 in the upper portion of said plate. This forms in n Fig. 1 a -hingeconnectiom aboutlwhich the Y cover member may be swung upwardly, `so

as to allow ready access to the-mechanismf I i. vv

of the exhibitor. kIt willv be apparent `that the 'tongues 13l lmay be readily Vdisengaged t yfrom "the `slits l14 when said ymember -is swung to a substantially horizontal posi-l tion.V Normally the lower `portion of the *f cover member is bolted to thevplatei3), as is 'indicated at 15..

y' For illuminating `the` described sign, iampff .sockets 16 are mounted in thefend portions of the cover member, up'on the latter by means of brackets 17,"said sockets receiving i and Windows 5.y
