I Specifio'ationof Lttersl atent. July 19 Original application fired January 4, ieias na in). a osaaflnivmea and this application fiIedCA To all whom it may concern:

Be itknown that l, HOWARD M. BARBER, a citizen of the United States, and resident of Stonington, in the "county of New London and State ofConnecticut, have invented anew and nsefulQImpiroWmnt inysheete Handl ng Machines, ing is a specification My invention relates to improvements in signature stitching and folding mechanisms whereby accurate fold ng of the signature along its stitched line is insured by means,

for adjusting. the parts while mechae nisms arefoperatin'g. V

My invention more particularly includes a rotary sheet carrier such, for instance as the cylinder forming partof a folding mechanism, grippers on the" carrier, {means for operating thegrippers' at their taking and releasing points, a st tcher mechanlsm,

its'table, a sheet stop forfthe stitcher table,

acam on the rotary sheet carrier arranged tooperate', the 'sheet stop, to permit the stitched signature to [be taken by the gripperson the rotary carrier attheproperitime,

and means. for adj Listing the position of they sheet stop with rs'pectytoithejtakingfpoi it ofsaid grippers whereby the grippers will be caused to close onto the signature at varying distances from the, head of the signature inthe rotary movement ofthe, carrier toaccurately ustfthe fold lineto bring it along the stitched line ofthesignature, the Whole. being accomplished while the machine; is. in

operation; it being understood that i the stitcher mechanismfis adjusted together with a the sheet stop to maintain; the predetermined distance between the sheet stop and the stitched line.

A practical embodiment of my invention is represented in the accompanying drawings in which- Figure 1 represents in end elevation so much of a sheet handling machine as will give a clear understanding of my invention, the female folding cylinder. being removed.

Fig. 2 is a section taken in the plane of the line Ill-II of Fig. 1, a portion of the female folding cylinder being shown.

Fig. 3 is a detail section at the sheet stop.

The stitcher table is denoted by 'l, the stitcher mechanismgenerally, by 2, andits driving shaft; by 8, which stitcher maybe 1 of any well known or approved construction adapted to stitch a signature While the move ment of the signature is arrested on the stitchertable. 'The signature may be fed onto'the stitchertable by the endless tape carriers 4:, 5. i

Ihe sheet stop for the stitcher table comprises a plural ty of fingers .6 fixed to a cross the cross shaft '10 supported in the side-- framesll, l2 ofthe machine.- The free ends s. ofthese. stop fingers 6, whenthestop is lowered, are located in the. circumferentialj l grooves13 .of the rotary sheetcarrier 1-1, which, in the present instance, is one member of a 'pairof ,coacting {folding cylinders,

the folding cylindersa This rotary carrier 14; is mounted on {a suitablecross shaft 18,

and it carries a set oftnmbler actuated grip-1 perslf), thetumbler 2001: which grippers is engaged by its actuating pin 21 at the taking point for the grippers and by the .actu: i

ating pin22 at the. releasing pointfor the grippers, this mechanism being known and, approved form.

'tion of the foldingblade15 and folding jaws 16, is not shownherein, butiitis understood. that it may be of any Well known or approved construction operative to cause the signature to be folded off from the carrier 14 onto the carrier 17. The rotary carrier 14 is provided with a peripheral cam 23 arranged in position to engage a stud or roller 24 carried by a two- armed lever 25, 26, fixed of well i t v s5 The mechanism forcOhtrolling the opera-e i to the cross bar 7 of the sheet stop, at the proper time to raise the sheet stop to permit the stitched signature to be transferred from the stitcher table 1 to the grippers 19. 'A rod 27 is attached at one end to the arm 26,

and slidably engages a stud 28. A spring 29 interposed between this stud 28and a collar 30, tends to yieldingly hold thestop in its operative position with the fingers 6 in the.

circumferential grooves .13 of the carrier 14. The means which I provide for adjusting the'fold line'with respect to the stitched line anism, 7

This shaft 35 is provided with a] suitable hand wheel38, and'by turning this hand wheel, the auxiliary frame is moved longitudinallyof the'table 1. The sheet stop is moved with the auxiliary frame of "the accomplished by providing upright shafts 39 whichhave a bevelgear engagement 40, 4:1,with the shaft 35, and a bevel gear eni gagement 4:2, 43, with the longitudinally arranged shafts 44 mounted adjacent :to the carriers 43 in fixed bearings 45 and at their other'ends having a screw threaded engage- 'ment with-studs46 at the 'free'endsfof the de ending "arm-s 8,9.
