WEB-WINDING MECEANISIVI.

Application inea Fetruary c, 192s. serial No. 617,219.

To all whom it may concern:

y Be it known that I, PHILO B. TINGLEY, a citizen of the United States, residing at New York, county of New York, State of New York, have invented a certain new and useful Improvement in Web-Winding Mechanism, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to data displaying devices of the double reel and web type, and has for its object to provide improved operating mechanism for the reels in devices of this character whereby said reels and the web wound thereon may be driven at a high rate of speed but may be quickly stopped at any desired point, which mechanism is so constructed and arranged as to be automatically operatively connected with the several reels alternatively in accordance 4with the direction of operation thereof, so that only that reel upon which the web is at any time being wound will be positively actuated, the other reel being freely rotatable by the web as it is drawn therefrom.

The foregoing and other objects of the invention, together with means whereby the same may he carried into effect, will best be understood from the following description of one form or embodiment thereof illustrated vin the accompanying drawings. It will be understood, however, that the particular construct-ion described and shown has been chosen ttor, illustrative purposes merely, and that the invention, as delined by the claims hereunto appended, may be otherwise `practised without departure from its spirit and scope. f-

In said drawingsf Fig. 1 is a plan view, looking substantially in the direction of the arrow A in Fig. 2, of the complete device, the top plate of the casing being partly broken away to show the interior mechanism.

Fig. 2 is a vertical section taken substantially on the line 2 2, Fig. 1, the crank disk and associated parts at the outside of the casing being indicated in dot and dash lines.

The invention is herein shown as embodied in a data-displaying device or changeable exhibitor comprising a casing 10 having a top plate 11 formed with a sight opening 12 through which may be observed the data inscribed upon a web or strip 13. The ends of said web are secured to reels or rollers 14 upon which said web is wound, rotation of said rollers in one direction or the other causing said web to travel in a corresponding direction past the sight opening| 12, so as to bring any portion thereof into a position to be read. The rollers 14 are secured to p`arallel shafts 15 suitably `iournalled in the side walls of the casing 10.

For operating the rollers 14 in the manner above indicated there is, in accordance with the present invention, provided a common actuator, herein shown as a gear or friction disk 16, which is located between and adapted for alternative operative engagement with cooperating gears or disks 17 carried by the ends of the rollers 14, respectively. The actuating disk 16 is journalled in ra movable support in the form of a swinging` arm 18 pivotally mounted -on a transverse rod 19 connecting the side walls of the 'casing 10` in such a manner as to render said disk 16 freely movable into engagement with either of the disks 17. The actuating disk 16 is at all times in close proximity to both of the disks 17, so thatl its range of movement is small, as indicated at B in Fig. 2, being just sufficient to .cause said actuating disk to clear one of the disks 17 when moved into driving engagement with the other. Engagement of the disk 16 with one or the other of the disks 17, when said disk 16 is rotated 90 in one direction or the other, is therefore insured.

The actuating vgear or disk 16 carries a coaxial spur pinion 20 which meshes with a spur gear 21 carriedby a shaft 22 suit- 95 -ment `with -the lower one.

of the casing and extending through said wall to the exterior of the casing. It will be seen that rotation of the shaft 22 and gear 21 will operate not only to rotate the pinion 2O and friction disk 16 in one direction or the other, but also to move said friction disk bodily in a direction 'depending upon the direction of rotation. For example, if the gear 21 be rotated in a clockwise direction, it will not only rotate the pinion 20 and disk `16 in a counter-clockwise direction but, due to the freely swinging. inountingof said Vdisk 16, will move the latter bodily toward the right into operative engagement with the upper friction disk 17 and out? of engage- The upper 1roller 1swill therefore be rotated in a clockwise direction to 'wind vup the web 13 and cause the saine to `move upwardly past the sight opening 12, said 'web being ydrawn from fthe lower roller 111 whose friction disk 17 is, at this time,'disengaged bythe actuating disk 16, so that said lower iroller' 'is freely rotatable by said web as it is drawn off. Similarly, if `the shaft l22 and gear 2l be yrotated in a counter-clockwise direction',` the friction disk 1G will be =moved finto Aengagement with the friction 'disk 17 -of the lower 'roller 111, and the latter roller rotated in 'a counter-clockwise direction to wind 5up 'the web 1S, cause the same to `travel downwardly Ypast `the sight opening 12, and be withdrawn from vthe upper roller iwh-ich is at lthis time free.

llhe shaft 22 carries at its outer 'end 'a pinion 2l-3 which meshes with )an internal gear 24 formed on a crank disk'25jou'rnailed on a stud 26 projecting from the casing 10, said 'crank ldisk having a vsuitable `operating handle 27. The mechanism described 'and comprising the internal gear 24, pinion 23, sgeai' "2l, and pinion `2O, provides a form vof speed accelerating gearing whereby the actuating disk 16 within the casing may be tlrivenat a relatively vhigh rate of speed and in 'either direction from the crank 'disk 25 outside the casing. The disk 16 is 1preferably larger ftlian the disks 17. thereby further accelerating ithe speed of rotation lof the rollers v11- and causing Jche web 13 to travel rapidly past the vsight opening 12. "Ili'e rollers 111- are made yas light as possible in -order to avoid the effect of inertia in startfing and stopping 'the vweb which may theretore be quickly started and Ic'aiused to travel at a rapid rateof speed, but which maybe instantly stopped at any desired point :by

arresting the movement of the crank 'disk 25. the effect of which is to cause the actuat- :ingdis'k 16 to move out 'of engagement with the disk 17 which it has been driving and into engagement with the other disk 17, so afsvto check the movement of the latter and the travel of the web 15. Thus, with the parts in the position shown in Fig. 2, if the shaft 22 be turned in a counter-clockwise direction to cause a downward travel of the web, it will be seen that the pinion will, during such operation, rotate in a clockwise direction, so that if the rotation of the gear 2l is abruptly stopped, said pinion 2O will tend to move toward vthe .right'upon the then stationary gear 21, thereby releasing the disk 16 from the lower disk 17, causing the `same to engage the upper disk 17 and check the rotation of the upper roller and consequently of the web drawn therefrom.

Having thus described my invention, I claim- 1. In a winding mechanism, in combination, a pair of rollers, friction disks carried by said rollers respectively, a single friction disk located between said first named disks in close proximity 'to'both and bodily movab'le into engagement with either, 'and means for yrotatingV and vsimultaneously bodily moving said last named disk in either direction;

In a winding mechanism, in -combination, a pair of rollers,'gea'rs`carried by said rollers respectively, a. gear located 'between saidiirst ynamed 4gears in close proximity to :both and freely movable into operative 7engagement `'with either and `rmeans for rotating and simultaneously bodily moving said last named gear in either direction.
