Rotary, and other, cutters designed to cut sheets o'l1 various materials, including,r metal, are well-known and constitute by themselves no part of nivpresent invention but the feeding and subdivision ot the initial sheets thereb)Y cut intopluralitiesof smaller sheets. or blanks, o'l required proiiortions and |erl;:1ii;'iilarity, hasI hitherto required nio-re manual skill, precision, rare, and time i on thepart ol the operators than is .induslriallv1 economical. The manual separation ol eich initial sheet `troni the pile o'l similar sheets in which it is reeeivcfgl by the operators. its suhseipient guidance to correct presentation to theA critters, the subsequent handling oi the resulting divisions in Order to insure their being; in turn fed and guided .in correct presi-mations to the saine, or other, cutters `i1o ell'eettheir" subdivision, into blanks ot required proportions and rectangularity, ivitlrleast possible Vaste of time and material, have hitherto required high degrees` ol'v tec-tile skill and intelligent ivatchlulness with whichiny invention disln other Worils,ln1y machine takes each initial .sheet separately troni theI pile, cuts it into the required subdivisions, and

delivers .the final prnduct, or blanks, 'of required proportions and reifftangularity, with unprecedented speed and without the inaterials being.` at any time, guided, or otherwise touched, by the operators. These results l believe to be attributable to my novel. devices and their combinations with each otlieri-ind with old devices as hereinafter deecribed it being understood that l do not. coifiline inf/S f to exactly the forms ind ari'ai'igen'ients illustrated in the drawinggs.y eruiivalents of which are to be also regarifled as wit-hin the purview of my invent-ion.

The conformation, I loca-tion andvdisposition' of said rests relatively to the platform, the pile, l2, of sheets, and the lifting device, are such that', (as

fshownf in Figs. -1, 2, and, moreparticularly,

in Fig. l2.) they are, when at' rest, in n-ormal position, inclined inwardly at' an angle sufficient to` project into the path, and'to ine sure yielding' contact thereby of the edge', of the sheet, during` its uplift, whereby they vlaterally guide it, as indicated by dottedl lines, in Fig 12,'and, after it has cleared them, are returned, usually by gravity, to

norniallyheld, by aid of gravity,'projecting into, and ina plane transverse of, the path- Wa'yof the sheets, and in which position' the Arests then underlie the suspended' sheet.

VVhen the sheet isatterward dropped, .in the saine vertical path through which it was lifted, by the" breaking of the exhaust, it

falls upon them, at which stage they act as restsor Ts disposed to support the thereon deposed sheet against displacement by gravity anrl with its .edge disposed directly inv thev path ot the advancing kicker 26. It will be noted thatas shown, particularly by Fig. 2, the tops of the rests h1 arefwhen supporting a sheet,on` a `level above that of the trucks or table 5S. flt will also be noted that, as shown Iriartieularly by Figs. 1 and yl, the rests (il are sparedeapart thus leaving between theln,helen'v their tops. an interA i space or pathway in which the kicker 2h is,

to an extent, recinfooatahle. -l't will also he noted that, as shown rmrticularly in Fiji. 'L the kicker or'driver 2G is normally ont ot contact Ywith the sheet supported on the Ts, is in alinenient with au edge of the sheet and with the said pathway, and thatthe con-e` struction is 4suchl that thelricker is slidably supported at all times out. ot contact with .the rests or Ts (il and their supporting .beyond its loca-tion prior to being struck.

It is obvious that a strokeof sach character coi'ild not with anyicertainty be delivered if the sheet were supported upon a therewith eoextensire, or' larger, surface or table with Whieh thekickei' must, or could, contact. in ot'lierwords, in order to effectively drive proper should vencounter the least possible Contact, friction or resista/nce other than that of the edge. of the sheet during its 'forward impulsion` or swing, andi conseqiieutly proyide means whereby itis slidably supported the sheet oft' of the rests or Ts to destina` tion, `have discovered that the kiq-ker.v Y

Anothorimportant cooperating element 'of'` my secondary feeding-device 'is the divider, 100, (FigsLl, tie-9) consisting of l a stationary bar, 100, of angular .cross-sew t1on,hav1ng its longitudinal angular apex upwardly presented in alinea-nent with the direction `of the cut made bythe central cut-` ter la." The divider is supported by the side frame members, 67 and 68, and serves to defleet and separate the halves of the sheet, as theyj 4 are advancing, from the delivery rollers, iand 6, of thevprimary cutting devices,\ to drop upon.V the receiving'ltable, 7G,

`lhe table, 76, is 'provided `with afguard?,A rail, V103, to arrest backward movement of Y the'thereto adjacent halt' of the initial I sheet while 'the-teeth, 78, are retrograding.

The operationof my machineis as l.iol-

having` been, `while ,onv one side ot the priy mary teeding device, manually loaded with L a pile, 112, of the initial sheets, c, is ,pushedy by theoperator into the position shown in 1` directly beneath the lifting ldevice 20.1" fThe shift lever, 98, is then swung, to actu?" ate the clutch to turn on the power, as hereinbetore described.- This causes the pneumatic suckers to descend to contact with the top sheet ot the pile and 'adhering thereto litt it tl'irough la vertical path, while, to an extent, guided, toward required position, by lateral contact oftl1e-fguiderests 61, which, though yielding, tend to shift an eccentric position oi the sheet without breaking the exhaust.,` The guide rests return to utheir normal position as soon aSthe sheet hasascended above them. It is thenA dropped in the said vertical path, by the breaking of the exhaust,r into correct, and substantially horizontal, position at rest upon the tops of the guide restspor Ts and exactly in the path of the driver 26,-which, being then sharply advanced, imparts a following-upy ystroke to the thereto adjacent edge of the The Iresulting .subdivi-f tion where they are more widely seperated by the divider bar, 100,and fall upon the vtable76, of the secondary feeding device.
