ADVERTISING DEVICE.

Specification of Letters Patent.

Application filed January 12,1906. Serial No. 295,712.

Patented July 3, 19046.

To all whom it may concern:

Be it known that I, JOHNV B. DANInLs, a citizen of the United States, residing at Newton Center, county of Middlesex, and State of Massachusetts, have invented an Improvement in Advertising Devices, of which the following description, in connection with the One embodiment of my invention will now l be described and then the particular features oi' the invention will be pointed out in the claims,`

In the drawings, Figure l is aront view of an apparatus embodying my invention. Fig. 2 is a side view thereof. Fig. 3 is a detail showing the way in which the web is wound up on the rolls. Fig. 4 is a top plan view of the gearing for driving the web. Fig. 5 is a detail of the driving means for one of the rolls; and Fig. 6 is a section on the line ai Fig. 5.

The web or apron on which the advertisements appear is designated by 3, and its ends are wound up onto two rolls 4 and 5, which are mounted in suitable bearings 6, carried by the supporting-frame 7. The web passes over direction- rolls 8 and 9, which are also driving-rolls, as will be presently described. The rolls 3 and 9 are driven from a vertical shaft 10, mounted in suitable' bearings 11, and said shaft carries at its upper end a bevelgear l2, which meshes with and is driven by a bevel-gear 13,011 a counter-shaft 14. The shaft 14 is driven by gearing which is constructed to give ita'n intermittent motion and also to reverse its direction of motion at predetermined intervals. To accomplish these results, I'have provided said shaft with two bevel-gears 15 and 16, which are loosely mounted thereon and either of which ma be clutched to said shaft by asliding clutcil member 17. The gears 15 and 16 are driven by a gear 24v slidably mounted on a drivingshaft 25, which shaft is continuously rotated in one direction by means of a suitable motor A26 of any suitable construction. As herein shown, the shaft of the .motor has a worm 27, which meshes with and drives a worm-gear 2S on a shaft 29, and fast to the ion 30, which meshes with and 31 on the driving-shaft 25. When the gear 24 is in mesh with the gears 15 and .16, the latter'gears rotate in opposite directions, as will be obvious, and the direction which the web or apron 3 travels depends on which gear, 15 or 16, is clutched to the shaft 14.

The gear 24 is alternately thrown into and out of mesh with the gears 15 and 16, thereby giving to the web 3 an intermittent motion. To accomplish this, I have provided the Ahub of the gear 24 with a groove 300, in which is shaft is a pinis acted upon by a suitable spring 32, that tends normally to disengage the gear 24 from the gears 1-5 and 16. Mounted on the drivl ing-shaft is a Worm 33, which meshes with a worm-gear 34; and rigid with said gear is a, cam member 35, which is adapted to engage one end of a .thrust member 36, connected to the lever 311. During each rotation of the worm-gear 34 the cam member 35 engages the thrust member 36 and throws the gear 24 into mesh with the gears 15 and 16, as will be obvious, and when this occurs the sha-ft 14 is rotated in one direction or. the other, dependent upon which gear, 15 or 16,'is connected thereto. When the cam passes out from spring 32 disengages the gear 24- omthe gears 15 and 16, thus disconnecting the metor from the counter-shaft and permitting the apron 3 to remain at rest. As soon as the gear 34 completes its revolution, however, and brings the cam 35 into engagement with the thrust member again; the countershaft will be again connected to the motor and the sheet 3 moved forwardly, as will be obvious. It will thus be seen that the sheet 3 has an intermittent movement, so that successive advertisements thereon may be brought into view. When the sheet has been entirely unrolled from one of the rolls ically shifted to reverse the direction of movement of the counter-shaft 14. This is accomplished by means of a worm 23, fast on the shaft 14,. which meshes with a worm-gear 22, carrying a pin 21, adapted to engage an arm 20, mounted on a rod19, and preferably having a resilient end 220. This rod is connected to the clutch-shifting lever 18, by which the clutch 17 is shifted.

The worm and gear 22 and 23 are so proreceived the forked end bf a lever 311which I drives a gear 8 under the end of the thrust member, the s iroo 4 5 onto the other, the clutch 17 is automat- IIO portioned that the gear 22 will make one revolution during the time that the sheet or web is wound from one roll completely onto the other, and when this is accom lished the pin 21 engages the arm 20, lthere y shifting the clutch 17 and reversing the direction of movement of the counter-shaft 14. It will l thus be seen that I have provided an automatic mechanism for intermittently moving the web 3 and for reversing said web when it has been completely wound from one roll onto the other.

In order to kee the web 3 taut as it is wound from one ro l4 or 5 onto .the other and to make it travel at a uniform speed, I preferably employ the rolls 8 and 9" as driving-.rolls and provide friction mechanism for driving the rolls 4 and 5. In this way the sheet 3 may be given a uniform m'otion regardless of the amount wound on either of the rolls 4 or 5. As herein shown, the rolls 8 and 9 are mounted on shafts 4()v andI 41, and each shaft has fast thereon a skew-gearY 42, meshing with a correspondin skew-gear 43, fast on the shaft 10. Loose y mounted on the shaft 41 is a sprocket-wheel 47, which is connected by a suitable sprocket-chain with a sprocketwheel 48, loose on the roll 4. The sprocketn wheel 47 carries a pawl 49, adapted to engage a ratchet 50', fast on the shaft 41, said pawl and ratchet being so arranged that as the roll 9' is rotated clockwise in Fig, 3, or in a direction to carry the sheet 3 upwardly, the sprocket-wheel 47 "'ll be driven', and consequently the sprocket-wheel' 4'8. The sprocket-wheel 4S has a frictional engagement .with the roll 4 suflioient to drive the latter to cause the sheet 3 to be wound u thereon; but when the sheet is nearly woun 51, fast with .the roll, by means of a spring 52. A

The sprocket f Wheel 470 is al'so connected to the shaft 40by a pawl-and-ratchet mechanism 53 54, which is disposed'oppositely to that on' the shaft 41, the pawl-andratchet mechanism 53 and 54 having such a construction that when the shaft 40 is rotated in a direction to draw the sheet downwardly the sprocketwheel 470 will be driven.' The sprocketwheel 470 is geared to a sprocketwh'eel 56 having a frictionalv connection with the rolly 5, similar to that between the sprocket-wheel 48 and the roll 4 and for a similar purpose'.

It will be '.fbvious that although both the shafts 4() and 4l are positively driven, yet when they are rotating in a dire'ction to feed the sheet or web upwardly the sprocket-wheel 47 will be driven, and consequently the roll 4 will be' rotated towind the sheet thereon; but the sprocket-wheel 470 will be held from roquently the sprocket-wheel 56 willv be held stationary. As the sheet or weh is drawn from the lower roll 4 the :stationary sprocketwheel 56 with its friction-surface acts as a brake to hold the sheet perfectly taut. When, however, the direction ofrotation of shaft 1() is reverse-d and the rolls 8 and?) are rotated in a direction to feed the sheet downwardly the sprocket-wheel 470 will be positively driven, and through the sprocket-Wheel 56 the roll 5 will `be rotated to wind the sheet thereon. 'During this time the sprocket-wheels 47 and 48 are'- held from rotation by means of ya su'itable stop-pawl 6l, and the sprocket-wheel 48 then acts as a brake to hold the sheet 3 taut. The sheet is held against these driving-rolls by suitable' presser-rolls 70, lwhich are vieldingly held against the sheet by means of suitable springs 71.

It will be seen form of driving means I haveernployed for the' sheet 3 said Asheet will always be kept taut without placing thereon sufficient strain tol tear or injure it.
