Be Ait known that I, TALo'r C. DEXTER; a i citizen of the United States, and resident of Pearl River, in vthe 4county of-lloekland and State of New York, have invented certain new and useful .lmlnorements' in Pamphlet- Feeding Devices for Stapling-Machines, of which the following is a specification. The present invention relatestoen appa* ratus by which signatures or-bunches of sheets, either `with `or without covers;lareV fed to suitable Etapling machinery and-aufV torlnatically ,positioned tofreceivel the1'r' mined points, to form books Gr.pamf'ihlete.;

My improved machine comprises minuit-f able feed table, preferably in theiform of ati angular saddle upon whiclrtlmI sueesivc; signatures or bunches of sheetiswoaiibefoiil renient'ly placed hy an opertor'in posiitionl to befautomatieally carried forward 'by a st i by step *feeding operation to receiie the hi ding staples, either at one'operitti af' in the case of small pamphlets. or Vin Spc` sive operations as in the case of larger pan.

the feed fingers gripping the signature against the strip. This operation of the feed fingers and feed strip is accomplished through the oscillating bell crank 7G 'mounted upon the plate T0, the first movcmentof the bell crank upon the pivot causing the rocking of the shaft 50 which carries the feed fingers 55, and the final increment of the bell crank by its cngag1 ment with one of the limiting stops 80 causin;r the reciprocation of the plate ((L feed strip G5 und shaft 50 carrying feed fingers tures are. fed in a step b v step manner through the machine, the feed fingers enga the 'signatures.successivelyr as they slibnorward upon the feedtable, and the operator placing a new signature in Lstartmg lposition as each signature is fed for- 5 war By the -trip clutch arrangement between the stapling mr chine proper and the shaft 136, the clutch is disengaged so as to retain the stapling machine at rest so long as there is no amplilet lin lace to be stapled, ,this being accomplis ed by tripping finger 161 resting by avlty in'- yertlcal position and intermittent yprevent- `1ng"the movement .of .the feeler 165,*wbich through .the trip mechanism connect' said feeler with the clutch actuating bloc 189, prevents ehsweiamwal pf he bleek .from the ath lof the clutch hook, so that the clutc is held in disengaged position..b When a signature on bunch o sheets reaches stapling osition, the trippingA finger 161 willbe move out of the path o ,thev feeler 165 so that the spring 197 will bepermtted tol withdraw the cam block 189 out of the path of the clutch hook, with the'result that the clutch will be engaged and the staplin ma chine will be operated to the signature or bunch of s eets resting in position.

In this latter case', my machine can be conveniently used by imparting feeding strokes of such len h .thateach amphlet will remain` in stap ing-*position uring two feeding strokes, so that it will receive two staples in its leading end and two staples in .its following end. l My invention provides an4v automatic machine by which amphlets and the like are completei bcun ation wit out the necessity of any. manipulation after the placing of the bunch of folded sheets or signatures in starting position upon the tab e in Vreach of the feed fingers. l

the combination of a feed table, a recipro- 'catory rock shaft -journaled adjacent to said table, means for impartin reciprocating and rocking motions to sai rock shaft, a
