FEEDeCARRlIAGrE STENCIL-MACHINES.

Levine/i;

To ill w from t may concern 1 Be it known that l, Geenen minnen, e citizen oit the United States of i-linerice, residing et Belleville,jconnty of St. Clair, Stete oi' illinois, have invented e certain new and useful `Feed-Carriage tor Stencillnchines, et which the followingv is? such :i "lull, clear, and enact description es `will enable any one skilled in the nrt to 'which it epperteins tonielre end use the seine, erence being' hed to the accompanying drove ings, to 'innig part of this specification.

lily invention relates to e feed carriage stencil machines and is particularly adapted tor use in connection with machines ot the generati type shown ind described in niv latent lilo. 1,131,956 of Merch 16, 1915. lt may, however, be used `with various other tjvpes` oi stencil cuttingv nnichines.`

The object oi my invention is to producen siinple sind compnet device ot the class described which will be reliable in operation and which will iirijnly grip the stencil sheet" so es to prevent the possibility et the sheet slipping; during the operation oi the device.

et the reel; bnr 111i. The rack bar is actuated by ineens of it geur Wheel 17 operated by any sniteble mechanism which is not illustrated, es it forms no port of the present invention.

20 ere clamping lingers each of which is provided with n recess 21 preferably in the forni oi circuler apertures. These recesses 21 ore adapted to cooperate with conical bosses 22 formed in the horizontal iisnge of the angle plete 11 to cleinp the stencil sheet so ns to etlectively prevent its slipping during the operation et its device; e portion ot the materiel of the stencil sheet being` forced into the recesses 21 by the bosses 22. Esch oi the fingers 2G is provided with e literal projection 23 bearing on one end n compression spring 211, the opposite end ci which bears against a member 25 forming; e. coin-f bined stop bloclr and fastening pin. liestin@I on the upper feces of thebloclrs 25 is sn actuating; ber 26 provided with slots receive pivotpins 28 which also serve tesecnre the parts of the device together. rlhe bnr 26 is also provided on its rein' fece with projections 29 adopted to coine into contzict with the curved end of lingers 20 end thus reise Afingers out oii Contact with the horizontal `flange of plete l1 when the bnr 2G is moved toward the left hand end el the cerriegge. This movement of the bar 2G is secured by Ineens of lever 30 pivoted on one of the pins 28 preferablyY adjacent to the center of the earrings and provided with :i coin slot 81 engaging with :i coin 32 cnrried on the reer fece of the ber 26.

33 is e channel plete forming n housing tor inclosing' the ber 26 and springs This channel ber is seoured'in position bv nien-ns of the nieniber 25 and pivot pins 2S which ports intend through the seid ber the vertical flange et the plete 11 und the` zich bei' 2G shown in F 6 and T The operation oi roy device :is follows:

llllhen it is desired to insert e. stencil sheet in the machine the lever il() is moved tonf'eri'l the right thus causing' the ber 26 to more to rd the lett so that the projections will with the curved ends oi the lin- 20 and conse ell or" seid lingers to inove simultaneously on their pivoted springs 22 against the tension of the pins 24;. The sheet -is new inserted between the lingers 20 und ,the horizontal flange of plete 11, the vertical portions of the fingers iorrninp; e stop for the :trent edge of the sheet. The lever 80 is novv again nioved into the position shown in Fig. 4 positively moving the bar 26 toward the right hand end of the machine and allowing the springs 24 to operate on the clamping fingers. This causes the bosses V22 to force portions of the stencil sheet into the recesses 21 lthus effectively clamping the sheet so that it cannot slip during operation f of the machines. 1

f on said carriage and provided with a recess,

and a boss on said stencil supporting member for forcing the stencil into said recess.

2. In a device of the class described, the combination With a stencil supporting member, of a feed carriage movable relative thereto, a stencil gripping finger mounted on said carriage and provided with a recess, and an obtuse conical boss on said stencil supporting member for forcing the stencil sheet into said recess.

3.111 a device of the class described, the combination With a stencil supporting member, of a feed carriage movable relative thereto,a plurality of stencil gripping fingers mounted on saidV carriage and each provided with a recess, bosses for forcing the stencil sheet into the said recesses, and means for simultaneously actuating said fingers to release the lstencil sheet.

4. In a device of the class described, the combinationV with a stencil supporting member, of a feed carriage movable relative thereto, a plurality of' stencil gripping fingers pivotedly mounted on said carriage, springs for independently actuating said fingers to grip the stencil sheet, and mea-ns for simultaneously actuating said fingers to release the stencil sheet.

5. In a device of the class described, the combination with a stencil supporting member, of a feed carriage movable relative thereto, a plurality of stencil gripping fin- Y gers mounted on said carriage, springs for actuating said fingers to the stencil sheet, a longitudinally movable bar for simultaneously actuating said fingers to release the stencil sheet, and a channel bar inclosing said springs and actuating bar.

6. In a device of the class described, the combination With a stencil supporting meinber, of a feed carriage movable relative thereto, a plurality of stencil gripping iingers pivotally mounted on said carriage, springs for actuating said fingers to grip the stencil sheet, a longitudinally movable bar for simultaneously actuating said fingers to release the stencil sheet, and a channel bar inclosing said springs and finger actuating bar.

T. In a device of the class described, the combination ivith a stencil supporting plate, of an angle plate movable relative thereto, a feed rack carried by said angle plate` a plurality of stencil gripping fingers carried by said angle plate, a finger release bar carried by said angle plate but movable relatively thereto, a channel bar inclosing said release bar, and means for actuating said release bar.

S. In a device of the class described, the combination With a stencil supporting plate, of an angle plate movable relatively thereto, a feed rack carried by said angle plate, a plurality of stencil gripping fingers pivoted to said angle plate, springs tor actuating said fingers to grip the stencil sheet, a finger ,release bar carried bv said angle plate but movable relatively thereto, a channel bar housing said release bar, and means for actuating said release bar.

9. In a device of the class described, the

, combination with a stencil supporting plate provided with a flange, of an angle plate niovz blc relatively thereto, a feed rack carried by said angle plate and forming therewith a guide channel for said flange, a plurality of stencil gripping fingers pivoted to said angle plate, springs for actuating said fingers to the stencil sheet, a finger release bar, a channel har inclosing said spring and release bar, and means for actuating said release bar. w

In testimony whereof, I have hereunto set my hand and aiiixed my seal.
