. This inventionrelates'toa front for a place of amusement particularly of the portable.

type carried bytraveling shows, exhibitions, or carnivals. I a I I p In the case of traveling shows, the'enclosure within which the exhibition is to be presented is customarily shielded from the'view of the public by'means of a front comprising a stationary canvas wall, or walls, upon which are painted suitable decorations or rep-- resentations calculated to appeal to the curiosity and imagination of the crowd, and having an entrance therethrough giving way to the enclosure. The vehicle by which the'show is transported from place to place not infrequently is specially designed for use as the entrance way over the floor of which the patrons pass to enter the show, the canvas walls extending outfroniopposite ends of the vehicle so as to flank the entrance.

The disadvantage of this type of front, however is that, regardless ofhow highly emblazoned, it has becomeso commonplace as'to attract little attention of itself and other means must be resorted to in order to arouse the interest of the crowd; and this is particularly true where the show forms'part of a carnival including a number of shows all having fronts more or less alike and each com peting against anotherfor patronage. The invention has for one of its objects to provide a front whichis'novel tO-a point approaching the spectacular so as to catch and hold the eyes of passersby. To this end,

the front of the present invention contemplates theemployment in place of the usual stationary canvaswalls, or in conjunction with such stationary walls, of a traveling curtain or panorama, suitably decorated, and having its ends connected together in the form of an endless belt wound over and driven between pairs of spindles. Inthe preferred form of the invention two such pano-' the Vehicle so as to flank the entrance carried by the vehicle, the spindles over which the curtains are drawn being continuously ro tated by a drive situated "belowthe floor of the vehicle. F or the purpose of insuringa positive driveof the curtains, 'the curtains are carried upon endless chains which engage suitable sprockets mounted on. the spindles.

l/Vhere'the spindles are arranged to rot-ate about vertical axes, which construction ordinarily will be foundmost practicable, each panoramic section includes a series ofjstiand:

ards located at spaced intervals intermediate the pair of spindles, and supporting tracks along which trolleys connected to the chains are adapted to'run, these trolleys servingto hold the chains against sagging or buckling and to maintain the longitudinal runs'of the curtainin a perfectly flat condition.

' 'At night, or when weather conditions make it desirable,the ends of the curtain can be on the lot,' a furth'er achievementof the in vention is the provision of a portable front of thez type just described which is readily Since an impor-' I disconnected and the curtains collapsed to out-of-the way position.

transportable and capable of quick and easy assembly and disassembly. Thus, the spin-,

dles, tracks, track-supporting standards,

curtains and chains may be quickly dismantled, the curtains rolled up on the spindlesand all the parts-loaded'into' the vehicle when the show prepares to change its location.

' In the accompanying drawings, I have illustrated a preferred embodimentof m invention. Figure 1 shows the front in elcvation, the'panoramic section on the left hand side ofthis figurebeing shown stripped of the curtain and borders, indicated in dotted lines, and disclosingthe parts lying behind the'curtain; Figure 2 is aplan of Figure 1, apart of the floor of the truck being broken awayto show the drive mechanism; Figure 3 is a vertical cross-section through the cur tain, illustrating the manner in which the curtainis supported upon theendless chains;

In the preferred embodiment of the invention about to be described the front consists of three major parts, namely: a truck 1 and two panoramic sections 2 and .3, as shown in Figures 1 and 2. The truck 1 is of the same general type as is commonly used by road shows for transporting its paraphernalia from place to place and serving in addition as the entrance to the enclosure behind the vehicle where the entertainment is being offered. A skeleton frame covered by canvas or other sheet material forms an arch 4 extending longitudinally of the truck under which arch the patrons pass to enter the enclosure. Folding out from theside of the vehicle towards the exterior of the front is a platform 5 to which a pair of collapsible steps 6 leads. Another pair of steps, not shown in the drawings, leads down from the truck, usually from one or both its ends, into the enclosure.

The two panoramic sections 2 and 3 are in every essential respect alike so that a description of one will suifice as a description of the other. It may be stated that these sec tions are arranged at opposite ends of the vehicle so as to flank the entrance. lVhile in the present embodiment the two sections are shown as extending in alinement, they might equally as well be arranged at an angle with respect to the entrance as may be determined by choice or by the particular conditions encountered at the place where a stand is made. Each panoramic section comprises a pair of spindles 8 and 9 located at opposite ends of the section around which the endless curtain travels. As best shown in Figures 5, 6, and 7 the drive spindle 8 is carried by a banner tower 10 comprising an elongated, openwork box structure adapted to be held in vertical position at the end of the truck by means of bolts engaging ears 11 projecting from the arch 4. The banner tower is open upon its side opposite that contacting the arch 4 and extending parallel to this open side is the spindle 8 journaled in bearings 12 fastened to frames 14 located at the two ends of the banner tower. The weight of spindle 8 is borne by a ball thrust-bearing 15 (Fig. 7 interposed between a collar 16 fixed upon the spindle and the lower bearing 12. Similarly at the top of the spindle a collar 17 clamped thereon is supported upon a ball bearing 18 whichin turn rests upon the upper spindle bearing 12. r

The spindle 8 extends below the bottom of the banner tower and has loosely mounted thereon a drive sheave 19, this sheave bearing against a ring 20 immediately below it which is keyed to the spindle 8. A clutch 21 is provided for operatively connecting the sheave to and disconnecting it from the spindle 8. This clutch comprises a pair of holes 22 lying upon opposite sides of and extending parallel to the axis of ring 20, these holes opening into a pair of companion recesses 23 formed in the hub of sheave 19. Pins 22a, fixed in the end face of a sleeve 24 loosely surrounding the spindle below ring 20, are adapted toslide within the holes 22 and normally project up into the recesses 28 to lock the ring to the sheave. The pins are with- .drawn from the recesses to disconnect the sheave from the spindle when the sleeve 24: is moved downwardly as by means of a handshifter 25 having a forked end embracing a circumferential groove on the sleeve 24. This clutch, as will later be explained, is designed primarily for use only when the curtain is being collapsed or the apparatus disassembled.

The two spindles 8 mounted in the banner towers located at opposite ends of the truck are driven by a cable 27 which extends between the sheaves 19 on the spindles. Supported upon a bench beneath the floor of the trucks is a motor 28, a drive wheel 29 operatively connected to the motor, and an idler pulley 30, an intermediate portion of the cable 27 being trained over the drive wheel so as to be frictionally driven thereby, and thence around the idler pulley as shown in Figure 2. A reduction gear box 31 is located between the motor 28 and drive wheel 29.

Keyed to the spindle 8 at appropriate distances from its upper and lower ends and partially housed within the banner tower 10 are a pair of sprockets 34 and 35, so that motion imparted to the spindle 8 by the sheave 19 will cause rotation of these sprockets. At the other end of the panorama sec tion is the spindle 9 extending vertically up from a flat weighted base plate 37 which anchors it in place, this spindle having rotatably mounted thereon a pair of sprockets 38 and 39, companion tothe sprockets 34 and 35 on spindle 8 and spaced a corresponding distance apart. An endless chain 40 extends between the two upper sprockets v34 and 38 mounted on the spindles 8 and 9 respective-:

order to overcome this'tendency the follow-- ingiprovision is made: Spaced at approximately regular intervals between theespindles 8 and 9 are a series of standards-43 asillustrated in Figure 3, these standards being detachably held in predetermined spaced relation by cross-bars 52. y The detachable cross-bars 52 may be of the vtype described in my Patent No. 1,674,734 of J une6,1928. These standards comprise two parts, an 11pper pipe section 44,;constituting the major length of the standard, and a short stub section 45 arranged to telescope within the lower end of the pipe section The stub section 45 extends vertically up from a flatibase' plate 46 and is provided with a plurality of transverse openings 47 spaced a short dis,- tance apart, eachadapted to receive a cotter pin48 which projects on both sides beyond the circumference of the sectioni The lower end of the pipe section 44 is enlarged and formedon diametrically oppositesides with corresponding right-triangular slots 49, the

edge of eachslot forming the hypotenuse of the triangle being stepped 'ornotched as shown inthe figure, sothat byinserting the cotter pin 48 through a suitably selected opening 47 and turning the base plate to bring the projectingends .of the cotter pin into engagement with an appropriate notch of the slot, a fairly nice vertical adjustment of the standard may be'attained to compensate for irregularities in the ground level on which the front is erected. l I s I Rigidly fastened to thepipe section 44 are an upper cross-arm 50 and alower cross-arm 51. The lower cross-arm 51 adjacent its ends and at equal' distancesfrom the pipe section 44 carries bearing blocks 53 each having a beveled under surface 54 and-also a flat upper surface provided with anoutwardly disposed lip 55 on the end of the block near.

est the standard 44. Uponthese blocks are supported I-beams 56'having welded upon their bottom faces-attaching elements 57 shouldered along their-outer edges whereby one shoulder may be inserted under thelip 55 and the other engaged by a clip 58 clamp ing over the outer end of block 53. As the clip is tightened upon the block as by means o'lja bolt, the tapered under surface 54 of the blockdraws the attaching element into firm seatingengagenient with the flat upperface s I r getheryoneof the two ends ofthe curtain,

of theblock,

The upper cross-arm 50 is similarly pro vided at its opposite ends with bearing blocks 53a engaging attaching elements 57a welded vtoI-beams 56a and having clips 58a for securing the rails to the bearingblocks, this structure being identical with that provided onthe lower cross-arm. 5l,exceptthat instead of the I- beam resting uponthe bearing blocks as in the case of the lower cross-arm, therI-beams are held suspended by'the bearing-"blocks so that the I-beams extend in salinementone above'the-other with their free sides disposed towardeach other, asshown in Figure-.3; I

series of standards 43' together make up upper and lower tracks 60 and 61respectively, occupying'positions a short distance above and below the straight runs ofrthe chains40 and 41., For maintaining the Ltr'acksections in registry, upon thezfiat under afaces offlthe Ibe'ams and overlapping their "ends' are fas- The I-beams 56 and by thef tened plates 63 having complementary tongue I and slot portions, asindicated-inFigure 4,

so that the tongue onthe endof oneI-beam will snugly fit within the slot on the contig'uous end of the. adjacent I-beam. .-On the banner tower -10 located above and" below the paths of the chains where they wind over the sprockets 34 and 35 onthe spindle 8 are permanently mounted arcuate sections of track 64 and 65; :and similarly supported upon cross-arms 62 (Fig. 1:) carriedby the and 39, arearcuate track sections66 and 67. These a'rcuate tracksections at their ends unite with the straight=-portions of' track leading'between the spindles8 and9whereby "spindle 9 above and below the sprockets 38 1 0 length of the tracks and corresponding trolr leys of the two tracks are connected for uni- The stays are detachably fastened tothe trolleys by means of upper'and lower stay cotter pins 69a and 69b. Tothese stays is attached the'panoramic curtain 71 by permanentfas teners fthe stayssserving as a backing to maintain thestraightruns of the curtain in flat condition, The curtain is preferably of one piece, (or a number of pieces sewed tor a r c i2o tary' movement by means of vertical stays 69.- I I As the trolleys are run together when the having a flap 7 3, as shown in Figure 9, adapted to overlap and button onto its other end after the curtain has been wound over the two spindles 8 and 9 in the process of setting up the front.

The point where the two ends of the curtain are united is so chosen that it corresponds to the place where the two chains are arranged to be disconnected. To simultaneously uncouple the upper and lower chains there is provided the following detaching device: Upon an ear projecting from' a stay 69 is pivotally attached an operating bar 76, and at equal distances upon opposite sides of its pivot are in turn pivoted rods 77 and 78. These rods are of equallength and connected at their extremities to coupling pins 79 and 80 which are slidable within guiding lugs 82 and 83 on the stay 69. Thepins 82 and 83 extend through and serve to unite two adjacent links 42 of each chain 40 and 41. When the operating bar 76 is swung about its pivot to the dotted line position shown in Figure 8, the couplingpins 79 and 80 are withdrawn from the links uncoupling both chains. T o latch the coupling pins in operative position, the lower end of the operating bar 76 is formed into, an arcuate seat 80 as shown in Figure 10, so as to normally embrace a side of the rod 78 when the operating bar 76 is in parallelism with the rod 78. The pivot connection of the rod 78 to the operating bar 76 is sufficiently loose, however, so that the rod 7 8 may be sprung outward to clear the sides of the arcuate seat when the detaching-device is operated. As shown in Figure 8 the disconnected links of each of the two uncoupled'chains are both supported upon separate trolleys. This is for permit ting the ends of the chains to be readily united by drawing the two trolleys together which action brings the corresponding ends of each chain in approximate registry and the coup-ling can be easily effected.

As will later be explained, when the curtain is to be collapsed, or the entire front dismantledas from time to time it must be either because of high winds or when moving to a new locationthe ends of the chains are disconnected in the manner just described and the trolleys are run along the tracks so as to bunch them together into a compact string, the sections of chains extending between adjacent trolleys being allowed to loop or fold loosely in a lateral direction. In order to maintain the trolleys from canting and binding on their tracks as otherwise might happen when the chains become slack, a spacing block 84 as shown in Figs. 8 and 11 is attached to each of the trolleys. The spacing blocks of the train of trolleys lie in alinement, and each block is provided at one end with a tapered nose 85 and at its other end with a corresponding tapered recess 86.

curtain is collapsed, the nose 85 on the end of one block fits into the recess 86 on the reverse end of the adjacent block as shown in Figure 11, so that the string of trolleys is maintained rigid which prevents their tipping and binding 011 the tracks.

In order to conceal the tracks and trolleys from view so as to lend an attractive appearance to the front, the outer run of the panoramic curtain, that is, the run of the curtain which is exposed to the view of the public, is overlapped at its upper and lower .marginal edges by borders 90 and 91, as shown in Figure 3. These borders are made of canvas fastened to flexible cables 92 extending along their rear or unexposed faces and disposed in slightly spaced relation thereto adjacent their edges. To afford intermediate support for the borders, upon the end of each of the standards 43 adjacent the outer run of the curtain-that is, that portion of the curtain being presented to public view-is clamped a vertical bar 93 and this bar at each end has formed side-byside thereon a pair of oppositely directed hooks 94. In setting up the front, the cable 92 may be snapped under these hooks and then drawn taut between suitable retaining means which holds the borders from sagging. The borders ordinarily extend only along the side of the front exposed to the view of the public and their arrangement and design will be largely a matter of choice. A central facing member 97 for uniting the two adjacent ends of the top borders 9O mounted above the arch.

In transporting the show from one locality to another, it is desirable that the curtain be rolled up in a compact manner. Therefore, before the panoramic section is completely dismantled the curtain is wound on a hollow drum 95 (Figs. 5 and 7). The drum 95 is carried upon a pair of spaced spools 96 which freely rotate on the spindle 8 with the lowermost spool which sustains the weight of the drum resting upon a ball bearing-98 seating against the hub of sprocket 35. A pair of pins 99 on the drum may be engaged at the beginning of the winding operation with the cotter pin holes in the ends of the stays 69 carried by the curtain, and a flange 100 of slightly less diameter than the sprocket 35 and located at the lower end of the drum provides a guide and supporting plate for the lower end of the stays 69 supporting the curtain during winding.

As has been previously pointed out, both panoramic sections are of identical construction and therefore require no separate description. The invention may be embodied in many different forms. For example the curtains may be constructed to travel in either vertical or horizontal paths, and in either event the path of travel of the curtain may be straight on the side presented to the down and collapsible construction described be employed. F urthermore, many of the,

features which are incorporated in the preferred embodimentdescribed above may-be? omitted without departing-from the invention, Especially is this true of the knockwhich may beemployed or dispensed with as desired.

When the front has been erected, it will be apparent that operation ofthe .motor 28 located under the floor of the truck 1,- will drive the cable 27 in the direction indicated by thev arrows in Fig. 2,; thus winding-of this cable over the sheaves 19, which will impart rota tion in opposite directions to the spindles 8.

idler sprockets 38 and 39 mounted on spindle 9, and the series of trolleys 72 supporting the intermediate sections of the chains will follow along the upper and lower tracks 66 and 67. The two curtains carried upon the outer runs of the chains of the two panoramic sections Wlll thllS travel in opposite'directions and toward the entrance way. The stationary borders and 9l skirting the upper and lower edges of the exposed face of the curtains constitute in effect a frame for the decorations continuously being brought into view by the moving curtain, Vhenever it is desired to stopthe movement of the curtain for any reason a' switch (not shown)- may be opened to cut off the current to the motor 28. p I

At night or because of unfavorable weather conditions, the curtains may be collapsed to protect them from injury. -When the curtain is collapsed it is desirable that equal portions of the curtain of each panoramic section shall lie upon opposite sides of the spindle 8. As. a preliminary step, therefore, the clutch 21 is operated by the hand-shifter 25 to disengage the spindle 8 from the drive sheave. This permits the curtain to be easily drawn along by hand until the disconnectible links of the chains lie at the point A (Fig. 2) just clearing the idler sprockets 38 and 39'on sprindle 9. The overlapped ends of the curtains are unbuttoned'to provide access to the detaching device which is operated in the manner previously described to uncouple the two disconnectible links of the upper and lower chains. The trolleys supporting the straight outer run of the chain AB may now be collapsed within the limits 13-0, the spacing blocks 84 preventing jamming of the trolleys on the tracks as they are bunched together and rolled along the tracks.

Thespindle 9 is next rotated in the opposite direction until the other ends of the upper and lower chains which were located at A are now located atE clear of the sprocke 's 38 and .9, thi reve s rota ion of spindle 9 transmitting, through the uncollapsed straight inner runs of the chains, reverse.

movement to the spindle 8 which feeds equal amounts ofthe' chains to the. collapsed. section 13-0. .The length of chain E.'F is now collapsed into the limits F-G. Due to slippage between the cable 27 and the sheaves 19, the disconnectible links of the chains:

of each panoramic section cannot be relied upon to lie at corresponding points in their endless paths whenzthe apparatus is stoppe I eventhough they originally mayhave occupied such position at the beginning of the drive,/so that if the disoonnectible links of one panoramic section upon stopping the curtain should occupy position A,.very prob-- ably the disconnectiblelinks on the other panoramicsection would occupy a different position. Consequently the primary'purpose of the clutches21 is to-free the spindles 8 fromtheir drives so as toallow each panoramic'section to be independently manipulated to bring the disconnectible links of each pair of chains to the proper points for uncoupling.

WVhen the device is to be moved to a new' location, the entire front must be dismantled.

The. upper and lower bordersare first removed by disconnecting the'ends of the cables and detaching their intermediate portions from the hooks 94, after which the borders may be rolled upinto compact bundles. The I curtain 71, to whichis permanently fastened I the stays 69,- is detached from the lower chain 41by removing the lower stay cotter'pins 69?). The canvas curtain with stays attached is wound onto drum while it is in perpendicularposition, this being done by first pulling:

outthe cotter pins 696 on the lower part of the curtain and as the chains are moved to advance the curtain toward the drum, the upper stay cotter pins, 69a, near the drum are pulled out. After the chains have; been; collapsed,

the clips 58 fastening theI-beam sections to the blocks 53 may be released; and the I-beam sections, together with the chains 40 and 41,

removed." TThe cross-bars 52 connecting the standards 43 and spindles 9 are next detached and these standards, together with the spindle 9, knocked down. Afterfolding up theplatform 5 and collapsible steps'6, the front will hwe been completely dis antled; and all the parts will beloa'dedronto the ve-' h'icle,'as shown in Figure 12, for transportation to'a newlocation, I
