Specification of Letters Patent.

Patented Nov. 24, 1914.

Original application med 11a 7, 1912, Serial No. 695,653. Divided and this application filed July 20,

1912. Serial 120,710,815.

To all whom it, may concern:

Be it known that we, WILLIAM H. BAN- zn'rr andEnMoNn KENNY, citizens of the United States, and residing, respectively,

' at Bergenfield, in the county of Bergen and .State of New Jersey, and at New York, borough of Richmond, in the county of Richmond and State ofNew York', have in- Number 695653.

A further feature of our improvements and an inherent part of the integral problem of consecutively producing envelop blanks from a continuous web is the mechanism for receiving the completed blanks and for de livering them in systematic order. Said delivery further includes the separation of those blanks into two classes accordingto their character as determined by the respective profiles of the two'cutting devices on the cutter roll.

Our improvements comprise arts. and combinations of parts illustrate in their preferred embodiment in the drawings accompanying this specificatlon where1n-- Figure 1 is a side, sectional elevation on line 1, 1, Fig. 2, of the upper part ofour improved machine. Fig. 2 is a. plan. v ew thereof. Fig. 3 is a side, sectional elevation on line 3, 3, Fig. 4, of the lower part .of my improved machine 'Fig. 4 is a. plan View of Iwhatis shown in Fi 3 and with those parts above line '4, 4-of mg. .5 removed. 5 isanend elevation corresponding wit Fig. 3Iand looking in. the direction of arrow A. Fig. 6'is a-diagrammatic layout of the paper web, illustrating-the several steps of transforming that webiiito envelop blanks. usual- 7sido -:framea-5,

in suitable bearings the several shafts, and to said frames are attached other parts of our improved mechanism. The continuous web ofpapcr 7 is preferably of a width to be used without edge trimming whereby the edges of the pveb form portions of the edges of the envelop flaps, see Fig. 6. Said web is led into the machine between rolls 8, 9

fixed to shafts 10, 11, respectively, and thence between feed roll 34 fixed to shaft 340 and rolls 29, 30 fixed to shafts 31, 32 respectively. Shaft340may be mounted in fixed to engagement with roll 34 bv means of spring 36 supported in bracket 37 and pressing against yoke 35.

The path of the web is preferably in a straight line frompthe time of its engagement by feed rolls 8, 9 until said web passes over 'and preferably downwardly around roll 34 whereits direction of travel is changed to a direction normal to its pre- 'vious direction. Below rolls 29. 30 and 34 are small feed rolls 38, 39 by which the web is delivered to the cutting mechanism to be hereinafter described.

For driving the various shafts and rolls thus far described we provide main sh ft 40 having pulley 41 fixed to the outboar end thereof. Fig. 2. Main gear 42 fixed to said shaft between pulley 41 and frame 6 drives gear 43 fixed'to shaft 15. Gear 43, through intermedia-tegear 45 onstud 47 in frame 6, drives gear 46 fixed to shaft 11 and gear 146 slightly smaller tha gear 46 and also fixed to shaft 11 drives g ar 48 fixed to shaftlO. By th'is'means feed rolls 8, 9 are driven at a surface speed slightly'less than that offeed rolls 29, 30 and 34 whereby web 7is advanced under tension. Returning now to main gear 42, said geacadrives'gear 49 fixed to shaft 20. Gear 49 through intermediate gear 51 on stud. 52 in framet, drives gear 53 fixed to shaft 340; saidintermediote 51 ahodrivee b gears 56, '57'driving respectively" gears 58',

' For urging .roll 39' to engagement with roll 38, shaft 62 may be hung vin 'bracketsras .66 pivoted on shaft 67 and springs as 68 employed, all according to -w'ell-k'nown construction. Q

The rotary cutting mechanism of ourimroved machine comprises a pair of rolls 71, the; former; having cutting blades '73., 7 4 thereon for coaction with the hardened surface-'ofroll 72. Said cutter roll- 71 is ofsuch a diameter and has its cutting members so disposed; as to produce two complete diamond shaped blanks at each revolution, and I hardened roll 72 is conveniently made of one 25 hfalf' the 'dia ete'r of roll- 71, thereby making two revolutlons .for each single revolution of roll 71.: Rolls 71-, 72zare'fixed to shafts 75,; 76,-,respectively,-' and said shafts have, "fifXGdJitO; their outboard ends coacting gears 178, grespe ctively, gear 77 being drivenintermediate gear 5 1thereabove. Roll sh aft76 has' bearings in opposite brackets "69,=- .pivotally' mounted on shaft 7 9. Said bracketsmay be adjusted to move cutter roll 35 7 2 toward or-away from roll 71 by meansjof sorews'as' fio andpusjh'pins as 81. Said push pins jas.- 81 have their rearward ends sup ported .in brackets as 83 fixedv to the side 'fr'ames'as 6 and may be'urged to their work 40 'by'springsu'as e82," thetension of said springs b ing ad usted bymeans of screw sleeves as 84, according to'well-known practice.

Directly below; cutter rolls 71, 72'are delivery rolls' 86,- 87 similar in all respects of mounting and ope at ion' to rolls 38, 39 abovesaid: cutter rolls. Roll shaft 85 has bearings in brackets 88 pivotally mounted bn' sha i 9 For directing the leading'end ofthe. blanksjrom the cutting rolls to engagethe right hand side, Fig. 5, are another nair ,of similar rolls 94, 95 for-engagement with i the right side of the-blank. Saidtwo pairsof opposite e'dge rolls are actuated at a speed slightly faster than the speed of the previous feed rolls and the cutting rolls. The object ofthis increase of speed is to separate each blank as severed from the leading end ofthe web, whereby space between consecument with-feed rolls 86, 87 we employ one orti ve blanks is provided a; facilitate the .op;

eration of the blank delivery mechanism,

which will presently be described.

Feedrolls 86, 87, 92, 93 and 91, 95 iraffetuated as follows One member of each pair is spring urged to""coaction withthelother member of its respective pair, as already described in connection with rolls 38, 3S The shafts of rolls- 86, 87 are geared together by gears 96, 97, and the shafts-of the succeeding pairs of rolls are similarly gear d together. Shaft 98 of rolls 86 has-fixed to its outboardend gear 99 which is driven from gear 77 on cutter shaft through in termediate 100-on stud 101 in frame-6.- For increasing the speed of feed rolls 92, 93 and 94, 95., a pair of coaxial intermediate gears 102, 103,-relatively fixed, are mounted on stud-104 in frame 6. Said. gear 102 is of.

equalsi'ze with andlisdriven by intermediate 100, while gear 103 is of slightly large!" sizeand drives intermediate gear 105Ywhich drivesgear 1.06 fixed to'shaftv107 of roll 92 on the one hand, and, on the other hand, through intermediate gears 108,109, supported-on studs in frame 6, drives gear 110 fixed, to shaft 111 of roll 94. v I

.The blank handling mechanism comprises two oppositely disposed receiving troughs, 1'12, 113 and a vibrating member-114therebetween. Said troughs eachcomprise a bot-fi tour as ,115 and. side '116 for trough 113. Said bottom is inclined downwardly toward said side wall to conform to the shape of the blank to be received thereby. Said trough members may he conveniently supported from'fixed parts of the machineas base 117 and side frame 6 by means of brackets as 118 and studs as 119, respectively; The receiving portions of said "troughs, opposite walls as 116, may be p blade 120. Said walls as- 116 and blade 120 have fixed theretoxedge guides 124, 122, respectively, for. guiding the edges of the downwardly .moving blanks. Each. trough as 113 is provided with a movable angular rovi ded with guide abutmentas 121 having frictional means as 1 spring held bolt 123 in engagement with slot 125. of bottom for partiallyresisting the movement of said abutment lengthwise in said trough as the blanks are delivered against the face 126 of said abutment. Vi brating member 114 comprises a plurality of upstanding arms 127 fixed to rocksl 1aft 128 pivoted in brackets 129, 130 fixed .to' side frames 5, 6, respectively. Said" arms 127 terminate. upwardly in thin flattened blades 131 which in the central position of their stroke lie in the plane of the descending envelop blanks, and said fingers are oscillated back and forth from one side to' the other of that plane. Saidoscillation is accom- 'plished as follows: Crank arm 1-32 is fixed to the outboard end of cutter shaft75 and oscillating arm 1331s fixed to the mm end of shaft 128. One end of connecting rod 134 is pivoted at 135 to crank arm 132 and the other end of said connecting rod is pivoted at 135 to rock arm 133. Said rock arm may be slotted at 137 to provide adjustment,

for the stroke of rock arm 133 and vibrating member 114. Bottoms 115 and 145 of trou hs 113, 112, respectively, terminate inwar ly in fingers 139, 138, respectively, and which fingers meet in the plane of the descending blanks. Spaces are thus provided for the operation of blades 131.

The operation of our improved machine is as follows: Main pulley 41 having been started in rotation in the direction of its arrow and the leading end of a web of paper being delivered to thebit of rolls 8, 9, said web is advanced forwardly over roll 34 and downwardly between said roll and its coacting rolls 29, 30; thence downwardly between feed rolls 38, 39 and between cutter rolls '71, 72. The partly severed blank is then guided by blades 90, 91 into the grip of edge rolls 86, 87, said rolls running at the same surface speed as the web. From thence the severed leading end of the web is delivered to feed rolls 92, 93 on the one hand near one edge of the web and lower down to rolls 94, 95 near the other edge of the web. Said rolls, being rotated at a speed somewhat faster than the speed of the .web, advance the now severed blank as 141, Fig. 6. at a speed greater than its previous speed, thereby separating said blank slightly 'from the succeeding leading end of the web from which another blank is about to be severed. Said blank 141., when first engaged by feed rolls 92, 93 and 94, 95 is still in the grip on one side, of rolls 86. 87, but the tension between opposing members of the pairs of the high speed rolls is greater than that between the opposing members of rolls 86, 87, whereby said blank is drawn from between said rolls 86, 87 as it is advanced dcr-mvardly by the high speed rolls. The opposite longitudinal edges of said blank pass between the adjoining members of guides 122 and 124 of the blank handling mechanism and are thereby assisted to keep their downward direction in the plane of the web. The leading end of the blank now impinges against the inreaching portions as 138, 139 of the trough bottoms and fingers 131 vibrating from their full lined position of Fig. 3 to theirdotted position in the same figure will engage the right hand face of the blank, delivering said blank against the upstanding face 143 of angular abutment 142. Said blades 131 then oscillatg to the right and deliver the next succeeding blank against the upstanding face 126 of'angular abutment 121. As said blanks accumulate against said upstanding faces, said angular a utments are slowly crowded outwardly in their respective troughs by the impact of said blades 131.

We claim:

1. A machine for making diamond shaped blanks including in combination means for continuously advancing 'a web of material, means for severing said web into diamond shaped blanks having their leading ends inclined transversely to said web, oppositely disposed receptacles for receiving said blanks having transversely inclined bottoms respectively corresponding with the inclination of the leading end of the blank, and means for delivering said blanks alternately to said receptacles respectively in approximate parallelism with said web.

2. A machine for making diamond shaped blanks including in combination means for continuously advancilig a web of material, means for severing said web into diamond shaped blanks, oppositely disposed receptacles for receiving said blanks on edge, said receptacles having transversely inclined bottoms respectively corresponding with the inclination of the leading end of the blank, and means for advancing one series of alternate blanks fiatwise in a direction approximately normal to its previous path of travel and for delivering said blanks on edge to one of said receptacles and for advancing the other series of alternate blanks in the opposite direction and for delivering said opposite series of blanks on edge to the other of said receptacles.
