Application filed November 26, 1912. Serial No. 733,596.

To all whom it may concern:

Be it known that I, \ViLLnur H. Banzn'l'r, a citizen of the United States, and a resident of Bergenfield, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Machines for Making 'indow-Emelop Blanks, of

whichthe following is a specification.

I parent window in the face thereo The, object of my improvements is to provide means for rapidly and accurately furnishing envelop blanks embodying those features particularly characteristic of envelops of the character specified. I

With these ends in view I preferably employ mechanism illustrated in the drawings accompanying this specification wherein- Figure 1 is a diagrammatic sectional ele ration of my improved machine. Fig. 2 is a plan view of a window envelop blank as produced in said machine. F1g.3 1s a diagrannnatic elevation illustrating the arrangement of gearing and some of the cam mechanism. Fig. 4 is an elevation, to an enlarged scale, of a detail of my machine.

Mounted on supports as 2, and resting against rail 3 is a pile of ordlnary envelop blanks 4. In front of and near the loweredge of said pile, transfer cylinder 5 is fixed to shaft 6. Above said cylinder 5, take-off finger 7 is oscillatably mounted at 8. Said finger 7 may be provided at its lower end with some suitable, well known means for engaging the front blank of the pile and, as finger 7 is oscillated to the right, Fig. 1, for delivering that blank to the grip of clips, as 10, on cylinder 5. I have illustrated suction means for engaging said front blank. Finger 7 is of tubular construction and is provided near its lower end with ports 9. Air may be exhausted at suitable times through hollow shaft 8 by some suitable exhaust means. For oscillating finger 7 I provide arm 41 fixed t0 shaft 8 and having at its lower end roll 42 for engagement with cam 43 fixed to shaft 6. Clips, as 10, are fixed to shaft 44, as is arm 45, having roll 146 for engagement with fixed cam 147. Said cam 147 may be held in fixed position relatively to cylinder 5 by some convenient well known means not shown.

To the right of cylinder 5 and coacting therewith is rotary blank-bed or platen cylinder 11 on shaft 12. Said cylinder is provided with clips as 13, for gripping the blank. Said cylinder may also be provided with one member 14 of a pair of cutting dies. The other member .16, of said pair of cutting dies may be mounted for reciprocation toward and from said die 14, on the lower end of slide 17 above cylinder 11. Said slide 17 may be conveniently mounted in guides 18, fixed to the frame of the machine not shown. Said dies 14, 16 are efficient for cutting the window 0 enings as 20 in the blanks as 40, Fig. 2. aid clips, as 13, are fixed to shaft 46, as is arm 47 having roll 48 for engagement with fixed cam 49.

For removing the severed window blank from the envelop blank I provide die 16 with spear 50 which, as dies 14, 16 coact, pierces the Window blank portion of the en velop blank in coaction with the window blank supportin edges of pocket 83 in die 14 of'rotary hea 11, and when that window blank portion. is severed from the envelop blank, conveys it upwardly as die 16 recedes, where it may be removed from said spear by means of stripper 51' mounted for reciprocation lengthwise slide 17. Said stripper is provided with pin 52 for coaction with fixed arm 53 of one of guides 18.

Above cylinder 11 rotary gummer 19 is fixed to shaft 21 and adjacent to the upper portion of -the path of travel of said gummer is gum delivery mechanism 22.

To the'right of cylinder 11 is the mechanis'm for delivering consecutively to the gummed faces of the blanks respectively, patches of transparent paper. This mechanismv comprises shaft 23 for holding a roll, as 36, of transparent paper in a continuous strip, upper and

lower feed rolls

24, 25, fixed cutter 26, below the path of said strip and oscillating cutter 27, above the path 0 said strip, forcoaction with lower cutter 26. Rotary patch-bed or delivery cylinder 28 fixed to shaft 39, is providedwith grippers as 29, and which grippers may be mounted for retraction below the periphery of said cylinder. 28. Said 'ppers, as 29, are fixed to shaft 54. in the es endof arm 55 and which arm is fixed to shaft 30 in cylinder 28. Also fixed to shaft 54 is arm 56 having roll '57 for engagement with fixed cam 58.

clips, as 29 to their inoperative positions, spring 59 being weaker than spring to, whereby said clips, as roll 57 passes around cam 58, will be first moved. outwardly and p then downwardly into coaction wit the periphery of cylinder 28 for gripping the leading end ot a patch portion 33.

For feeding web 32, rolls 2t, 25,-are geared together by

gears

61,62, and coaxially fired with roll 25 is ratchet 63. Said ratchet may be rotated intermittently from cam 64 by the usual mechanism therefor, particularly illustrated Fig. l. 'ldoroscillating upper knife 2'? lemploy cam 65, fined to shaft 39 for rotation with cylinder 28. .Said knife is fined to the outer end of arm 66, freely pivoted on shaft '87 ot-roll 2d, and said arm 66 is operatively connected with cam 65 by the usual ineans. Below cylinders it and 28 are enacting delivery rolls 3?, 38 respectively.

To enable die lb to coast with die it it is necessary that the rotary movement oi cylinder ll be intermittent and that said cylinder have a period otrest in the position shown in Fig. l. 1 therefore provide intermittent driving means comprising in its preferred embodiment the well known rotating arm 70 having roll ll for successive engageroent with slots as l3 in dislr'l'2. Arm id is lined to shaft 7% and which shalt may be considered the main shaft of the machine and may be rotated at uniform constant speed from some source of power not shown. Slotted disk 2 is fined to shalt '?5 as is near in driving gear 'llfined to shaft '6. 'Disk K2 is illustrated as having four slots 73 and gear 76 is four times the diameter of gear 7?, whereby tor each revolution ct shaft 74,

' shaft rotates one quarter of a revolution and shaft ti rotates one complete revolution. Gear 78 also lined to ti drives gear 79. fined to l2 and gear l9 drives gear 219 fixed to shaft 21. ,Gear 219 drives gear 80 oft guer 22. Gear 7'9 also drives gear 81 bred to shaft 39 and gear 81 through inter mediate gear 82 drives gear 92 of discharge roll 38. Gear 92 drives gear 8t oi the other discharge roll 3?.

59 For actuating slide'l? l crank 85 to shalt 'Z't'and by means or? 'pitman 86 connect that crank with arm 8? fined to rock shaft 88. Ann 89 is also fixed to said rock shaft b8 and has its bilnrcate outer end in engagement with ime we in slide it".

"lhe operation of my improved machine is as follows: .d. quantity ct envelop blanks.

ll of suitable profile having been placed upon the supporting rods as 2 and against bar 3, main shaft 74 is started in rotation at uniform speed in anti-clockwise direction. As illustrated in Fig. 1., finger 7 has previously been oscillated to its dotted position where it engages the lower end of the foremost blank and has then been swung to-its rice-tea roll-line position into a channel provided therefor in the periphery of cylinder 5 and has delivered the lowermost end of that blank into the grip of clips as 10 ofcylinder 5, just at the end of that cylinders last prior rotation. Therefore, now, immediately upon the commencement of the rotation of shaft 74 from the position shown in Fig. 3 cylinder 5 will commence its rotation in anti-clockwise direction and carry the envelop blank downwardly and then upwardly to engagement with cylinder 11 whereupon grippers as 13 of that cylinder grip the leading end of the blank. Grippers l0 thereupon release their hold and the blank is carried around upwardly on cylinder 11 until that cylinder presents its die it in the position shown in Fig. 1. At this time roll 71 of arm '70 will be just leaving that slot 73 indicated by position 73 of Fig. 3. At this time crank 85 will be moving upwardly, thereby. causing, through the connections described slide 1? to move downwardly, presenting" die 16 to engagement with die 14% whereby window opening as 20 will be cut in the blank. Then as crank 85 moves downwardly about shalt It slide 1'? will be withdrawn up,

wardly. During the coaction oi? dies 16 and id spear 50 will pierce the window blank portion of the envelop blank and as said die 16 is retracted upwardly will carry that window'blanlr away from the envelop blank.

'lhereupon pin 52 will engage arm 53, whereby stripper 51 will push the window blank of? from engagement with spear 50. Said window blank will then fall from the machine or may be conveyed away by some convenient known means not shown. Arm 70 then continues its rotation and upon roll 71 engaging the next succeeding; slot of disk 72, cylinder ll will begin another rotation in clockwise direction. presenting the window margin of the blank to gummer 19 rotating" in anti-clockwise direction in suitable time therewith. Said glimmer thereupon deposits gum 3i ardund the border of the window opening 26.

During' that rotation of cylinder 11 just previous to the one in which it coacts with the gurnmer. web 32 of transparent paper from roll 36 has beencadvaneed by feed rolls 2%., 25 by means of the mechanism pro vided therefor, over lower knife 26 in position to be gripped by clips as 29 of delivery cylinder 28. Clips 29 then grip the forward end of said web to cylinder 28 and shortly thereafter knife 2'? descends and severs window patch portion 33. Said patch portion 33 is then ready for delivery against the gummed margin of the window in the envelop blank on cylinder 11 and as that blank passes downwardly to the right, said patch will pass downwardly to the left and be delivered against said gummed window margin. As said patched blank passes beltd lllltl I

tween cylinders

11 and 28 the patch is firmly squeezed ontothe blank, the clips of the respective cylinders release their hold and the patched blank is delivered to the. grip of

rolls

37, 38 by which it is discharged from the machine.
