Specification of Letters Patent. Patent d J 29 1920 Application filed October 16, 1918. Serial No. 258,367.

chanical means which control the movement of the sections of the band forming the pictu res.

iVith the above and other objects in, view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combina tion and arrangement of parts as herein fully described, illustrated and claimed.

, 1n the accompanying drawings, forming plan; 7

Fig. 4 is a diagrammatic view showing a modification of the apparatus having one exhibiting face; I

Fig. is a modified arrangement-for im parting to the band an increasing and decreasing velocity; s

Fig. 6 is a diagrammatic side elevation of the mechanism shown in Fig. 5.

Referring to the drawings, 10 is an open framework formed of suitable material, which has on its opposite faces a plurality of band supports. 11 disposed in a vertical row. Each support is rigidly secured to the frame with suflicient clearance between the from which the band is fed. A similar bearing 12 is provided on braces 14 of the frame to receive another roller 13 for similar purposes. A band 15 is threaded successively from a support on one face to thosupport on the other face until the other roll 13 is reached. lirconsequeiice, the illustrated band is zigzagged between the supports of the band onthe two faces of the frame.

Motion is imparted to the band 15 by endless belts 16 which may frictionally engage the band on the supports 11, or perforations may be provided in the band and teeth 17 on the belt. The belts are supported by rollers 18 which are mounted on tension arms 19 secured to the frame 10. The arms are so set that the belt portion nearer to the supports is drawn against said supports. The lower parts of, the belts are engaged by driving pulleys or sprockets 20 which are revolubly mounted-off center on plates 21,

the plates being coupled to driving shafts 22 with which therefore the members 20 are eccentric. To prevent the belt portion in proximity to the band from swaying to and from the band as the driving pulley moves in its eccentric path guiding rollers 23 are provided below the lowest band support The two driving shafts 22 are coupled. to a shaft 24 by bevel gears 25. driven from a suitable motor 26. ing conical pulleys 27 and 28 are mounted to revolve on one of the shafts 22, the two pulleys being united to revolve together. The pulleys have a clutch extension 29 with which a clutch member 30 maybe engaged and which is constrained to revolve with the shaft 22 whereby the pulleys are coupled to the shaft on which they are mounted. Each pulley is provided with a belt 31 which engages a corresponding cone pulley 32 and respectively, the two pulleys being mounted on independent shafts 34, the pulley 32 converging in a direction opposite to the pulley 27 and the pulley 33, to that of 28.

Each belt is engaged by a corresponding fork '35, the two forks being united by a sleeve 36 which has athreaded engagement with a screw 37 to which motion is imparted by a belt 38 engaging a suitable pulley 89 on the extension 29 of the pulleys 27 and 28. In consequence the two belts are shifted simultaneously on theconical pulleys and different speeds will be'imparted to the two shafts 34. These shafts carry pulleys 40 The shaft 24 is Converg which are coupled to the rolls 13 and whereby said rolls are driven at different speeds .aceording to the quantity of band wound thereon.

The other shaft 22 carries a worm 41 with which a worm gear 42 meshes. The gear 42 has a plurality of apertures 43 at the mar gin adapted to be engaged by removable pins 44. The arm 45 lies in the path of the pins, the arm being connected with a reversing mechanism 46 which controls the direction of rotation of the motor 26 and, therefore the movement of the bands in either direction. By varying the angular distance between the pins 44 different lengths of bands may be used in the machine. Suitable yielding means 47 are provided for retaining the arm 45 in displaced position until again moved by a pin.

In Fig. 4 the band is zigzagged over pulleys 48 located in the rear, and also over pulleys 49 positioned between the band supports and the pulleys 48. Said pulleys 49 are mounted in a suitable frame 50 which can be adjusted vertically and, therefore,

take up any amount of lag necessary to properly adjust the sections of a band on the supports 11. The band, if desired, may be made endless, as indicated in dotted line in said figure. Suitable guiding pulleys would have to be provided for the purpose.

\Vhen the picture formed by the sections of the band is to remain immovable for a comparatively long period of time, the movement of the band is accomplished by means of a rigid frame 51 having teeth for engaging the perforations in the band. The frame has also horizontal slots 52 at the top and bottom engaged by crank pins 5-3 to which motion is imparted from a driving shaft Springs 55 draw the frame toward the band against the resistance of which the crank pins work when they draw the frame away from the band to move it without displacing the band.

In cases where the eccentric driving pulleys 20 cannot be used, a varying velocity. can be imparted directly to the shafts 22, by which the bolts 16 are driven, in the following manner (see Figs. 5 and 6). On the driving shafts 22 a pulley 56 is provided. Motion is imparted to said pulley and therefore to the shaft 22 by a pulley 57 constrained to revolve with a plate 58 which carries a crank pin 59. An elongated slot 60 of a crank 61 is engaged by the pin 59. The crank is constrained to revolve with a shaft 62 which is driven by the motor. The bearing 63 for the shaft 62 may be adjusted so that the distance between the axes of the shaft 62 and the plate 58 may be adjusted and, therefore, the speed of the shaft 22' varied.

To render the inanimate signs more realistic, I provide a talking machine the disk carrier 64 of which is driven from the shaft 24 by suitable bevel gears 65. The sound box 66 has securing means 67 for pinching or clamping an inextensible flexible member 68 to the sound box, one end of which is con nected to the sleeve 36 of the shifter of the differential mechanism. The other end of the flexible member 68 is connected by a spring 69 to the arm support 70 of the phonograph, guiding pulleys 71 being provided for the flexible member to maintain the proper relation with the sound box. The sound box 66 is also connected by an inextensible flexible member 72 to an arm 73.

A cam 74 is )rovided on the shaft which extends from tie arm 45 to the reversing mechanism 46, said cam being positioned in proximity to the arm 73 over which the flexible member 72 passes. The engagement of said cam with the arm will raise or lower the sound box. To the arm support 70 two rigid arms 75 are secured which are adapted to be disposed to each side of the sound arm.

Each of the arms 75 carries an inclined plane 76. The inclined plane 76 near to the center of the disk is adapted to engage the needle of a sound box and raise it from the sound box as it is advanced by the flexible member 68. The return to the margin of the disk is accomplished by the spring 69 which has been tensioned by the flexible member 68. WVhen the sound box is returned by the spring 69 it is raised from the disk by the cam 74, and when it reaches the incline 76 it will be engaged by said incline; and as the movement is reversed, the cam 74 will slacken the flexible member 72. The movement of the sound box will be taken up by the flexible member 68, and the incline 76 will allow the needle to come into engagement with the disk on the carrier 64. The inclines 76 are adjustable on the arms so that the point of engagement of the needle with the disk and the disengagement of the needle from the disk may be controlled in accordance with the length of the band used.
