These rods are mounted et one end onrocls 29, md et uo icc the other end on a cross bar 30 resting lagainst a bracket 31 secured to the end ot' the frame. stops to be lifted above the sheet when desired, so that the sheet may be pulled out.

Mechanism constructed in. accordance with the invent-ion Will include means for dividing the sheet, so that it may be delivered in parts. In the particular construction shown, it comprises a slitter 32 mounted on an arm 38 carried on a shaft 34 extending across the machine. The slitlter is located over and'coperates with the abutment roll 2,

Constructions embodying the invention will include means for forwarding the sheet, said means acting on each side of the cut formed by the dividing means and coperating with the means which hold the original edges ot the sheet in forwarding the same. lll-'bile these means may be varied, and While the operating means may be varied, in the particular construction shown, a b aket' is provided which serves to support one. end ot a shaft 36 having a sprocket Wheel 37. The bracket 31 is provided With an extension 38 which serves, through a suitable stud. to support a coperating sprocket ivheel B'Q A flexible gripper carrying chain 40 runs (iv r the sprocket Wheels 37, 39, the Wheel 37 being the driving Wheel. The 'chain 40 (see Figs. 1, et, and 11) is provided With tivo blocks 41 each of which has a horizontal extension 42 which` serves as one jaw of a gripper mechanism. The corresponding jaw -13 of each gripper is carried on a rock-arm ,44. These arms 44 are pirated on studs Ll-vextending from the blocks 4l. The grippers are normally held closed by springs jl-(i and are opened to seize the sheets by cams i7 fixed inside the arms of the brackets 35. The arms 44 carry rolls 48 which contact With these cams. The grippers are opened. to' release the sheets by cams L19 secured to a chain guide 50, this chain guide being supported at one end by the bracket 3S and at. the other end by extensions 51. from the bracket 85. It Will be understood that the under run ot' the chain 40 is above thesheet path and that the gripper iau's in opening, therefore, cross the sheet path.

In order to prevent the jaws 43 from pressing upon and possibly tearing the sheet, means l.n'iay be provided for permitting the sheet te bend away from the grippers and tor lifting the sheet so`that its The-cutaway place iin this table filled- V66 by' a leaf the front end of which is.l

seizure by the. grippers. is insured. While these means may be varied, in the particular construction illustrated, the sheet, after leaving th\A abutment roll, is received on a table or platform (see Fig. 3) which is cnt away about midw r of' its forward edge.

This construction enables the formed by a tongue 54 flanked by recesses which are in the path ot the gripper jaws 43 as they swing downward. This leaf' is hinged at 5G to the table 52, and suitable Ameans is provided for rocking the leaf downunder side (see Figs. 4 and 5) tivo brackets 57 to support a short shaft 58. This shaft is provided with an arm 59 to which is secured an'arm 60 extending from a hub 61 loosely mounted on a cross-shaft G2. This hub G1 has extending from it an arm 63 to which is secured a spring rod construction 6st of ordinary type which is operated from a cam G5, suitably mounted in the machine. In the operation of this part of the mechanism (see Figs. 4, 7 and 8) as the sheet advances across the table 52 and as the ripper is opening, the eat 53 is rocked downvard. At the time the gripper is fully opened, the parts occupy the position shown in Fig. 4. Assoon as the grippers are beyond the edge ot the sheet, the leaf is lifted, as shown in Fig. 8, thus bringn'ng the edge of the sheet into position Where its seizure by the gripper is insured.

Certain novel features of constructionl claimed is not to be confined to thc particular construction herein shown and described,

as changes and variations may be made therein without depart-ing from the claimed invention.

What is claimed is 1. A sheet delivery mechanism including in combination means for advancing a sheet fiat. said means including,r devices for holding the original edges ot the sheet, means for dividing the sheet, and sheet forwarding means acting to positively seize the sheet and operating on the sheet on each side next the cut termed by the, dividing means.

2. A sheet delivery mechanism including in combination means for advancing a sheet flat, said means including grippers operating on'tlie original edges otthc sheet, a slitter forV dividing the sheet, and sheet forwarding grippers operating on the sheet'on cach side of the cut formed by the slitter.

3. A sheet delivery mechanism including in combination a pair of traveling flexible gripper carriers one on each side ot' the sheet path, gripper.; on the carriers, av slitting mechanism for dividing the sheet, and grippers operating on thel .sheet on each side ot the out formed by the. slitting mechanism.

-l. In a. sheet delivery mechanism, thc com ideeen? icinetion with e peil* et tteveiin tienibie Y gripper carriers one on each sie et' the sheet path, of actuating Wheels toi' the cer'- iiers rota-,ting on exes which are normal to the piane ci' the sheet path, e slitting mechenism, intemedate grippers operating en the sheet on eech side et the cut termed by the slitting mechanism, and gripper actuating devices,

5. In e sheet delivery mechensm, the combinaticn with sheet advancing means includq ing a. pair of propelling rolls and en :ibut ment mii cepereting therewith, cf e slitt/er operating on the abutment teli, a pair of tienibie gripper carriers one en each side 0i the sheet path, actuating Wheels for the certieis rotating on axes which ere normal to the piene o the sheet peth, grippers on the carriers, and intermediate grippere operating en the sheets en each side et the cut formed by the siittei.

t3. A. sheet delivery mechanism inciuding in ceinhinetien means foi' advancing the sheet fiat, seid ineens including e device for holding the originel edges et 'the sheet, means for dividing the sheet, and a gripper' mechanism lcceted over the sheet path, the
