Abstract

ABSTRACT OF THE DISCLOSURE
A movable picture poster supported by a take-up roller and a supply roller. The drive mechanism of this picture poster unit is composed of means to vary speed, vary direction, to start and stop as well as means to control the time during which the picture poster is exposed for viewing.

Description

SUMMA~Y OF THE INVENTION
__ My invention relates to a device for the exhibiting of a continuous series of individual picture posters.
A picture frame is fitted with a pair of rollers on which a roll of pictures i6 mounted, with the rollers connected to a reversible drive shaft.
Means are supplied for varying direction as well as speed of the roller, together with a means for stopping or starting the rotation of the rolls, as well as means for controlling the time during which an indi~idual picture on the roll is exposed for viewing between the rolls. Means are provided to replace a roll of pictures.
A major advantage of my invention is that it provides a method of controlled view for one of a series of picture posters on a roll.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Turning now descriptively to the drawings, in which 6imi1ar reference characters denote similar elements throughout the several views, FIGS. 1-4 show the construction of the automatic poster picture frame 10 which is composed of a rectangular base board 70 -:
onto which the picture roll 16 is mounted on ~eed roller 11 ana take-up roller 15, Feed roller 11 i8 anchored by means of pedestal bearing bracket~ 12 along the top edge 64 -~
o~ the base board 70, with a beveled gear 13 fitted ` on one end of the axle 72 of horizontal hollow roller 11. A take-up roller 15 secured to the opposing bottom edge 66 of base board 70 by means of pedestal support bearing brackets 14, with beveled gear 17 fitted to the end of axle 73 of hollow roller 15.
Bevel gears 13 and 17 mate with bevel eears 28 and 23 respectively fixed to shaft 26 that is supported by bcarlng brackets 27, A gcar 30 fixed to shaft 26 . .

is engaged by a spur gear 32 of drive motor 31 for rotatably driving rollers 11 and 15 in either direction of feed. An idle roller 18 with end guide collars 19 which functions as guides for picture poster 16 i~
positioned below ad~acent to and parallel to roller 11 and is supported by meane of pedestal support bearing brackets 12. A second ~dle roller 20 with end collars 21 is mounted ad~acent and parallel to roller~ 15 and supported by pedestal support bearing brackets 14.
Mechanically operated coil spring ten~ion and clutch asæemblies 24 and 25 are connected respectively to bevel gears 22 and 23 so that axial movement of drive shaft 26 engages one of the two bevel gear~ 22 or 23 with the other bevel gear rotatine freely on shaft 26.
Four pedestal support bearing brackets 27 ~upport the drive shaft 26.
Picture poster 16 is wound about roller 11 and pa6~es over ldle roller 18 and past the ~iewing aperature 88 of the device to feed over idle roller 20 and take-up roller 15.
A punch hole 33 is located in the vertical edge of picture poster 16 for orientation of an individual plcture on po6ter 16 with the viewing aperature 28. A roller contact switch 34 is mounted " . .-~03635Z 5 on the base board 70 with the switch 34 roller poei-tioned so as to contact punch hole 33 as it rolls past switch 34, When punch hole 33 of the moving poster picture 16 becomes aligned with theroller contact swltch unit 34 to activate switch 34, a solenoid 35 is controlled by swltch 34 to ~top drive motor 31. Control buttons 42 are mounted on a panel 37 to control speed and direction of motion of drive motor 31 and to start and stop the motor 31. Alter- - ~ ;
nately a timer device 47 n~y be mounted on alternate control panel 45 to regulate the duration of stoppage of motor 31 for each individual picture or poster 16 ; when the device is in autom~tic drive.
The rollers 11 and 15 are each housed by hollow frame 48 which is fastened to the external edges of base 70.
FIGS. 5-12 show the construction of the drive mechanism 50 of the automatic picture poster unit 10. Sleeves 51 and 52 are connected to each end of drive shaft 26. Clutch assemblies 24 and 25 are connected to sleeves 51 and 52 and to bevel gears 23 and 28 respectivel~r. Picture rollers 11 snd 15 . j , are respectivel~T connected to bevel gears 13 and 17 which are in engagement with bevel gears 23 and 28 respectively. Each clutch brake asse~blies 53 and 54 , ~' ' , -:'~

consists of a tension flat spring 57 fitted wlth a friction lining 58 on the inside ~urface of spring 57, Anchor bolt 55 holds spring~ 57 in position, Each bevel gear 13 and 17 has a large diameter boss 59 on which the spring 57 is wound, The sleeve 51 fits onto the drive shaft 26 and is locked in position by screw 60, A compresslon spring 71 fits inside the recess of sleeve 51, and one end of a coil spring 72 fits into slot 62 of sleeve 51, The sleeve 51, with compression spring 71 and coil spring 72, fits into the housing of clutch assembly 24, and the other end 73 of the coil spring 72 is attached to the housing of clutch assembly 24, The housing of clutch assembly 24 : bears against bevel gear 23, as a clutch, Bevel gear 23 is driven by the coil spring 72 under constant tension, Since obvious changes m~y be made in the specific embodiment of the invention described herein, such modifications being within the spirit and scope of the invention claimed, it is indicated that all matter contained herein is intended as illustrative and not as limiting in scope,

Claims

The embodiments in which an exclusive property or privilege is claimed are defined as follows:

1. A picture poster viewing device for the viewing through an aperature of a single individual picture on a strip imprinted with a plurality of pictures comprising, a picture frame adaptable for mounting to a flat surface, said frame formed with an open viewing aperture, a strip of flexible sheeting upon which a plurality of pictures are imprinted, with the opposed ends of said strip mounted upon a pair of rollers, rotatably mounted in spaced parallel orientation, each located on an opposite side of the viewing aperature from the other, reversible motorized means to rotate both rollers so as to wind the strip upon one roller and unwind the strip upon the other roller, said motorized means rotatably linked to a drive shaft, with each roller fixed to an individual roller shaft, each roller shaft fitted with a first bevel gear, about the boss of which flat frictional spring means are externally wound to serve as a clutch brake, each said first bevel gear being individually meshed with a second bevel gear, each of said second bevel gears being joined to the drive shaft by an individual clutch assembly incorporating a coil spring joining the drive shaft to the clutch assembly in constant tension and a compression spring biasing the respective clutch assembly against each of the second bevel gears, with the frictional spring means about the boss of each of the first bevel gears being wound in an opposite direction from the frictional spring means wound about the other first bevel gear, so that in a given direction of rotation of the drive shaft, one of the first bevel gears is under braking torque causing the clutch assembly of the associated second beveled gear to slip with relation to the drive shaft, and retarding the motion of the roller associated with said first bevel gear.

2. The combination as recited in claim 1 in which the frictional spring means externally wound about each first bevel gear boss consists of a flat spring fitted with a frictional lining on the surface of the spring in contact with the boss of the said first bevel gear about which it is wound.
