envelops having a transparent patch applied i thereto, and is particularly applicable to from a roll of aper.

The object of this invention is to provide means which will apply a patch to a blank while said blank is at rest in combination With rotary means for advancing the yblank to the patch applying mechanism. Afurther object of this invention is to provide mechanism for cutting a blank from a roll of paper, advancingsaid blank to the patch applying means and applying the patch as above described.

To accomplish the aforesaid objects, I nd it best to stop the blank during the patch applying operation by the means shown in their preferred forms in the accompanying'drawings, which villustrate also all the mechanism required for the attainment of the objects stated.

, tating a blank, parallelogrammic in outline,

and the means for advancing the blank to the'patch applying mechanism and Fig. 12

is a partial vertlcal section and front viewv on. This type ofimachine combines the advantagesof simplicity, speed of operation and accuracy 1n carrying out the steps neces sary to make a complete envelop. Blanks of the shape shown in Figs. 3, 5 and 11 may be cut by revoluble cutters in the machine, (Figs. 3 and 11) from a roll of paperand then advanced to the patch applylng means, or suitable blanks already cut maybe fed to sald patch applying means by any of the feedlng devices well known in the art, and which devices are not shown in the drawlngs. f

The blank cut by the mechanism shown in Figs. 11 and 12 is of the form well known in the art, being substantially parallelogrammic in outline, thereby economizing in paper. The feeding mechanism comprises

feed rolls

26 and 27 on shafts 42 and 43' 'i respectively, mounted in

frames

1 and 2, said feed rolls coacting to advance the web of i paper 63, which is supplied from a suitably supported roll of paper not shown. Revoluble cylinder 28 on shaft 44 carries the four

cutters

67, 68, 69 and 70 for making the edge cuts in Web 63. Said cylinder 28alsov by suitable mechanism said chips being withdrawn by a suction pipe or other suitable mechanism not shown, or dropped into a receptacle provided therefor. The cutting mechanism shown in Figs. 11 and 12 differs from that shown in Figs. 3 and 4 only as regards the shape of the blank shaping and blank severing cutters and the-description given above will suflice for both.

Referring now particularly to Figs. 11 and 12, segmental cylindrical roll 32 0n shaft 51 coacts with roll 33 on shaft 52 .for advancing the cut blank. Short cylindrical segmental -blank advancing roll 34 on shaft 53 is placed as close as is permissible to

conical rolls

40 and 41 on

shafts

55 and 56 reand 41 is preferably in the plane of advance of the blank, said plane being preferably horizontal, the axes of said rolls therefore converging so that shaft 55 carrying roll. 40 must be terminated at some point preceding the intersection of the axes of said rolls, the shape of which is preferably that of frustra of cones. Stand 62 placed in advance of theA intersection of the axes of said conical rolls supports

shafts

55 and 56 placed-diagonally of the machine and inclined downwardly and upwardly respectively. Supports 64 and 84 are also provided near the extremities of

shafts

55 and 56.

Short segmental blank forwarding roll 36 on shaft 58 coacts with revoluble roll 37, both of said rolls being placed as close as is permissible to

conical rolls

40 and 41 without interfering therewith, said rolls 36 and 37 coacting to gri blank 65 when the conical rolls release t eir hold, to advance the blank without interfering with the rotation of the blank. Segmental roll 38 co-acts with revoluble roll 39 for advancing the blank to the patch applying means and is sovgeared and of such diameter as to increase the' speed of travel of the blank to allow time for the stopping of. said blank later for the further operation thereon as hereinafter described. Said roll 38 acts in the same manner and has the same function in Fig. 11 and in Fig. 3, and the description givenapplies to both gures.

The operating mechanism of the parallelogrammic blank cutting machine is as follows: pulley 3, obtaining power from a source not shown is mounted on shaft 42 as is gear 4, which drives gear 5 on shaft 46.

Cutter carrying cylinders

28 and 30, chip gripper roll 60 and se

ental rolls

32 and 34 together with the ro s coacting therewith, are driven by gear 5, through the train of gears, 6, '7, 8,19, 10, 11, 12, 13 and 14, t0-

i shaft 57 supported in frames 81- and 82, and

gear 15 on the same shaft through the train of

gears

15, 155, 154, 152, 151 and 310 acting together with' suitable gears not shown.

The conical rolls 40 and 41 are used 'to turn the blank 65 from the skewed in which it is cut from the web 63 1nto the proper position for easy further operation thereon, such as patch applying, folding and gumming. In connection with the cutting mechanismdescrihed above, the atcli applyosition ing means shown in Figs. 1 an 2 or Figs.l 7 vand 8 maybe used, as shown in Figs. 3

and 4.

Referring to Figs. 1 and 2, forwardin vrolls 135 and 136 take hold of the blan after it has been severed from the web and properly speeded up, or after it has. been fed to said forwarding rolls by a' suitable feeding device not shown.

interfering with the patch applying operation. Gum is supplied to gumming ledge 137 by 'gum roller 130 revolving in gum box 129.

is positioned directly under belts 94 to support the blank during the application of the patch. Oscillatory'alining stops 127 on Said rolls 135 and 136 are mounted on

shafts

209 and 210 Plate 95 is supported on rods 126 mounted in the side frames 8l and 82 andv shaft 223 are timed to engage the leading corners of the blank to stop andlproperly aline v said blank, after which oscillatory presser feet 87 mounted on shaft 205 come down on and hold the blank stationary on the belts 94, until the patch has been applied and the blank is ready to be advanced again. The hopper 139, holding a pile of cut patches 131, and comprising plate 96 having attached thereto rods 97 with toes 138 at the lower end of said rods to support the pile of patches, is'supported by a bar 98 bent at right angles and having 'a dovetail shaped portion to fit a dovetail slot in frame 82, said ar 98 and the hopper 139 attached thereto being given a reciprocating vertical motion l as hereinafter set forth. Se lental roll 89 on shaft 218 coacting with rol .90 on shaft217,

is timed to grip the leading ilap of the blank.

when said blank is released bypresser feet `87. Roll 90 carries belts 94 and with segment 89 advances the blank for further operation-thereon, such as the gumming of the `bottom seam. Strips of gum are preferably placed on the under side of the side flaps by gumming ledges 106 on roll 91 mounted on shaft 220, said ledges 106 receiving the gum from gum roller 122 on shaft 222, said gum roller rotating in gum box 128. Dlsks as 93 on same roll 91 coacts with roll 92 on shaft 221 forl advancing the blank continuously to suitable mechanism for completing the envelop, as for instance folding devices, shown conventionally in Flg. 1.

For the hopper 139 land the pile of cut 'patches 131 may be substituted the roll of paper 140 and suitable means for feeding 'and applying a strip of said roll. (Flgs.

and 8). Rolls 141 and 142 on

shafts

143 and 144 respectively, intermittently feed the paper over guide 147 having an upwardly inclined cutting edge 148 and supported to the side frames by rod 149, said paper passing under blade 150, which is supported in a manner similar to hopper 139 by a bar similar to bar 98, as 298. Edge 148 and the edge of blade 150 are positioned in the same vertical plane so that a downward movement of blade 150 shears ofl" a strip of paper and carries said cut strip down to the blank, which is positioned with the gummed window under blade 150, whereby said strip is pasted over said window.

The actuating means for the blank advancing and patch applying mechanism is as follows: Segmental advancing roll and speeding up gear 154, which is driven from another part of the machinel through gears 151, and 152 (Fig. 3) and gear 155 (Fig.

10) in turn drives forwarding roll gear 109. Through the latter rotation is transmitted to the'gear 110 of the coacting roll on shaft 210. Gumming roll 85 is driven through

gears

111, 113 and 112, while

rolls

89, 90 91 and 92 are driven by the train of

gears

114, 115, 116, 117, 118, 119, 120 and 121. The oscillatory motion of presser feet 87 is obtained through cam 103 on intermediate shaft 214, said cam rocking shaft 20'5 through l roller 104 and link 105. Stops 127 on hub 88 and operating in slots 99 of plate 95 are given their oscillatory movement by cam 125 on shaft 218 through roller 124 and link 123 attached to shaft 223. The reciprocating motion of hopper 139 and of knife blade 150,v

is obtained through

rollers

101 and 132 at the end of

bars

98 and 298 respectively, said rollers being operated by cam 102 on shaft 215. The intermittent motion of rollers 141 and 142 is given by ratchet wheel 145 onv shaft 143 through pawl 146 operated by forked lever 157 having a roller 133 actuated by cam 156 on shaft 216.

It'is evident that the shape of .the blank suitable mechanism and speeded uivby segment 38 is. passed on to the forwar ng rolls 135 and 136 which advance said blank to gumming roll 85, where a strip of gum is eration of my improved machine applied around,- the window of the blank,

and the blank passed on tothe belts 94. Said `belts carry the blank forward to engagement withalining stops 127, which are timed to oscillate downwardly to en age the leading flap ofthe blank. The lts 94 cause the blank to tend to move forward, the blank thereby adjusting itself until stops 127 engage the leading corners -of the blank, when'l the blank can no4 longer slip and .is therefore properly alined. The blank is held at rest on to the belts in its alined position by the oscillatory presser feet 87,- which come down on the blank and hold said blank stationary justl as

stops

1,27 movel away from the blank corners. Said blank is held stationary while hopper 139 or blade 150 come down over the gummed opening with the pile of patches 131 or the cut strip of paper respectively. In the case of the pile of patches 131, the last patch will adhere to `the gummed surface, -and on the upward movement of the hopper, will be drawn'out from toes 138 of rods 97 and separated from the remainder of said pile. Presser. feet .87 are now raised, allowing the blank to be continuously forwarded by segmental roll 89, I

which is timed to grip the blank just as said presser feet let go. Said blank may now be continuously advanced tothe bottom seam gummer 91 and to any vother mechanism for further operating thereon.
