This invention relates to an apparatus for winding upon and unwinding from reels a flexible connection or belt which is adapted to be used for displaying advertising, for displaying pictures mounted thereon, or for bringing progressively into view any other matter Which can be inscribed upon, carried by, or make up a belt or other flexible connection.

Among the objects of the invention are to provide an improved automatic means for keeping the matter to be displayel continuously in motion so that all portions thereof Will be progressively displayed in an advan- 15 tageous manner at the desired rate of speed.

' An important-feature of the invention oonsists Vin an improved mechanism for causing the power of the motor to be shifted from the operation of one reel to that of the other reel, so that one reel Will be stopped and the other reel automatically put into motion at the proper times.

Other objects are to improve apparatus of the class to Which the invention pertains with respect to simplicity and durability and positiveness in operation.

Still other objects and advantages may hereinafter appear. Y

Referring to the accompanyingdravvings Which illustrate the invention,

Referring in detail to the drawings, the main' elements of the apparatus are the ilexibleconnection or. displaying belt 9 Winding upon: z'tndfunWindingV from the spaced apart z"reels lQand' 151 VWhich are respectivelymounted upon vertical shafts12 and 13k and move 59 the displaying section of said belt through the exhibition case or compartment 14. vThe operating means Will now be described in detail. The motor 17 operates the primary driving shaft 1 8 upon which is secured a Worm 19 that is in mesh With a relatively 55 large Worm gear Wheel 20. Said Wheel 2O is secured to a main transmission shaft 21 Which in turn has a pinion vgear 22 secured to it, the latter gear being in mesh With gear teeth 23 formed on a continuously rotating clutch 5.0 member 24. On one side of said clutch member 24 is a cooperating clutch member 25, and on the other side thereof is a'cooperating 4clutch member 26. To the cooperating clutch member 25 is secured 'asecondary transmity65 ting shaft 27, and to the other cooperating clutch member 26 is secured a transmitting shaft 28. Said shafts 27 and 28 aline with each other and have their adjacent ends in close proximity, thus providing a supportive and bearing for the hub portion 30 ofthe middle clutch member 24.

In order to operate the clutch elements Which have just been described, a clutch operating frame is provided,said frame consisting of the upright arms 31 and 32 Which are respectively pivotallysecured at their lower ends to the supporting feet orV lugs 33 and 34. The upper ends of saidupright arms 31 and 32 are pivotallyV connected to the ends of a 8o cross arm 35 having nearl its center an up- Wardly extending yoke 36 whereby said cross arm 35 is shiftedvback and forthv by means of Y a crank 37 Which Vforms apart of a shaft 38 operated by means described later.- Thes movements of arms 31 arecontrolled by 'a guide or bracket B (see Figs. 4 and 5) Which is supported from standard S by means of arms T. Y l

The upright clutchshifting arm 31 is pro- 90 vided with a yoke y31a which embraces a groovedv hub 25a With :which ythe f shift'able clutch element 25 is provided, and the upright arm'32 is provided with `a yoke'32EL Which cooperateswith a grooved hub 26a with which 95 the clutch element 26 is provided. Thel central, continuously rotatable clutch element 24 is provided with holes Y39 Which are bored l therethrough as well shoWn-inF-igure 4,A and themeveble @sich elemeetseed 26 er@ te? Vmally to hold the clutchin the neutral position shown in Fig. 4 wherein said springs 27c and 28c are extended to the limit of their re-r` siliency. l l

Returning now to the shaft 38 which carries the clutch operating crank arm 37, said Vshaft 38 has fixed thereto a cam plate 45,*said cam plate having at one side Vof said shaft a segmental portion 46, and at its other sidel an operating arm 47 which is actu-ated by a lever 48 pivoted between itsends to a supporting pivot 49 so asto operate in a vertical plane. The lower end of said leverv 48 is positioned with a part 48a thereof between a pair of yoke arms 50, and when said yoke is reciprocated, as will presently be described, said lever is caused to oscillate in such a manner that the upper end thereof sweeps back and forth across the free end of the operating arm 47 of cam plate 45.V To said lever 48 is secured an overthrow spring 55the straight upper end portion55a of said spring extending within a yoke or guide 56 carried by cam plate in order to afford a lost motion operative relation between said spring and cam plate.` Cam plate 45 is provided at one side Vwith a stop shoulder 45suwhich cooperates with a stop 8(7), and at'the otherV side with a l stop shoulder 45t which cooperates Vwith a sto 81. Y n

5am plate 45 is provided at one side of its operatingarm 47 with acamusur-face 47 and at the other side of said arm with a cam surface'47b,.andrthe rounded upper end o f the Yoperatinglever- 48 sweeps across irstrone and then Vthe other of these c am surfaces in oplerating said cam plate. The coiled lower portion of spring lV isseated upon and secured Yto a stud. 551 which is carriedr by lever i v 48 a short distanceabove its supporting pivot .49, This arrangement of YVsaidspring, cam plate andlever causesa reverse throw to Vbe given to saidcam plate whenever the adjathe end of the al'soengages sprocket wheel 65' on shaft 28.

-The upright shaft12of reel 10 has fixed to it a bevel gear 12 which is driven by a bevel gear 12b Vfixed to shaft 28, and the other reel shaft 13 has fixed to ita bevel gear 13a which is driven by fabevel gear-13b fixed to shaft 27.

" Y, The exhibitionicase 14 may be shaped and supported in any suitable manner in order to Y display to advantage the pictures or other matter carried by the sheet or connection 9.

In the drawingssaid case 14 is shown sup-V ported by the top cross piece 7 O of a frame having end pieees or uprights 71 anda base member 72. Said case-14 is. secured to the lower side of top piece by means of a spacing member 73 thus providing room for the top bearings 74 and 75 of reel shafts 12 ano portion of which is located a lamp 77 adapted to illuminate the exposed portion of the connection9.

In operation, the motor is started-and kept running thus rotating continuously primary shaft 18 carryingI worm 19 which meshes with worm gear wheel 2O fixed to main transmission shaft 21, said main transmission shaft 21, Vby means of its gear 22 rotates contin- `aously the middle clutch member 24. Assuming said clutch member 24 to be engaged by the pins 40 of the left hand shiftable clutch member 25 as seen in Fig. 4, the operation of the motor will cause continuous rotation of the shaft 27, the latter shaft by means of gears 13b and 13L will rotate upright shaft 13 ofl reel 11 thus unwinding the sheet 9 from reel 10'and winding it upon 'reel 11.

The rotation of reel 1() thus 'caused will also rotate reel shaft 12, its gear12a, gear v1 2b and shaft 28. Shaft 28 through sprocket wheels k65, 61a and sprocket chain 64 will rotate screw shaft 61. Such rotation of screw shaft 61 will move theymember 50i mounted thereon, say toward the left as seen in Figs. 1 and 6. Continuous left hand movement of member 50V together with the lower end ofA lever 48 will cause the upper end of said lever 48 to move toward the end of the cam plate arm 47 untily said arm reaches the left hand dotted position of 6 wherein .the shoulder 45s ofthe cam plateA is brought into approximate engagement with thevstop 80 at which time 'the upper;L

end of lever 48 will free itself fromk the end of arm47 and the spring55 will thereupon give a sudden right hand overthrow movenient to the cam plate thus bringing-its right hand shoulder 45t into contact with the stop` 81. When this occurs said cam plate will by meansof the shaft. 38 to whichit is fixed,

and the crank arm 37 carried by said shaft, (seeFig. 4) actuate the cross bar 35jof the clutch 4shifting frame thus withdrawing the f;

.pm740 of clutch member 25 from the central clutch member24'a'ndat the same time mov-` engagementi withV the central clutchA member 24; 'i i ing the pins40 of the clutch memberf26 Linto plate 41:5 takes place the traveling member 50 begins to move in the reverse direction along said screw shaft 6l.

The various gears are of such arrange 6l will cause the traveling head 50 to actuate the cam plate 45, operate the clutch and stop the rotation of one reel and start the rotation of the other when the proper time comes for doing so, that is to say, after the entire matter to be displayed has been run across the display casing.
