BARBER WEE FEEDING MECHANISM Fi led April 12, 1930 2. Sheets-Sheet 2 INVENTOR E ATTORNEYS Patented Jan. 31, 1933 7 SONS COMPANY, OE-WESTEELY, RI-IODE ISLAND, A CORPORATION OF. DELAWARE WEB FEEDING MECHANISM Application filed April 12,

' My inventioncomprises certain improvements in web feeding mechanism whereby webs'of heavy or light stock can be successfully fed by providing the web feed rolls with removable web margin engaging rings which may be retained on the rolls when heavy material, such as;magazine stock, is to be fed and which may be removed when light or weak material,'such as newspaper stock, is to be fed.

My invention further comprises a change speed drive for the said web feed rolls, which drive includes a change gear mechanism for driving the feed rolls at oneangular speed when the rings are retained and at a greater angular speed when the rings are removed, whereby the web whether it be of heavy stock or of light stock may be fed at a predeten.

. mined speed by said rolls.

My invention more particularly comprises a gear train drive including two coaxial driving gears of different diameters and a shiftable intermediate gear arranged to be brought into mesh with either one of said driving gears. V

V A practical embodiment ofmy invention is represented in the accompanying drawings, in which v Fig. 1 represents a diagrammatic end elevation, showing the web feed rolls with their web margin engaging rings retained, and the shiftable intermediate gear in mesh with the driving gear for feeding the web of heavy stock; a

Fig. 2 represents a detail side view of the same;

Fig. 3 represents a diagrammatic end elevation showing the web feed rolls with their web margin engaging rings removed and the shiftable intermediate gear in mesh with the other driving gear, for feeding aweb of light stock;

of the web feed rolls With the web margin engaging ringiremoved therefrom Fig. 7 represents a side view of one of the web margin engaging rings. w I In the web feeding mechanism illustrated in the accompanying drawings I have shown four webfeed rolls 1, 2, 3,4. 1 In Figs. 1', 2 and 4 the web feed rolls areprovid'ed with web margin engaging rings 5 "removably mounted thereon. These rings are shown as split, for facilitating their mounting on and removal from the web feed rolls. The rings are also shown as having overlappin'gaends and as being removably secured on theweb feed roll by means of screws 6. "T hesejre movable web margin engaging rings 5 may HOWARD n1: BARBER, or PAwoA'ruoK, oo-nniio'rroutr, assls non ,TO, 0. B, corrTRE L a;

be of any predetermined thickness, to-cause the roll to properly feed a web of heavy stock. In Fig. 1, I have shown aheavy web 7 as passing around the web feed rolls in engagement with the removableweb margin engagin g rings on said rolls, while inFig. 3, I have shown a thin web 8 as being passed around these web feed rolls with the Web margin engagingrings removed from said rolls.-

The drivefor the web feed rolls isherein shown as a gear train in which two coaxial driving gears 9 and 10 are shown as mounted on a shaft 11 which carries a gear '12 driven, in the'present instance, from a'p'inion 13. An intermediate gear 14 is shiftable to two differentpositions' in two planes, to bring it into* mesh with either the driving gear 9 by the web feed rolls; In Fig. 1 the shiftable intermediate gearl is shown in one posi tion Where it meshes with the driving gear 9while in Fig. 3 it is shown inanother position where it meshes with the drivinggear 10. In both of these positions the shiftable intermediate gear' 14 meshes withithe wide faced gear 15, which gear 15 is at alltimes connected wit-h the web feed rolls through the train of gears 16, 17, 18, 19, 20 and 21.'.

Fromthe above description it willbe seen that by simply shifting the position "of the intermediate gear 14 to bring-it into engagement with either the driving-gear 9 or the driving gear ofthe gear train, the web feed rolls may be driven at a predetermined suro face speedwith or without their web margin engaging rings so that the web whether it be of heavy material orlightmateria1 is driven at said predetermined speed, thereby permitting the feeding of webs of heavy or light stock in the same web feeding mechanism.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not intend to limit myself to the particular embodiment herein shown and described, but
