To all whom it may concern:

Be it known that I, ABRAHAM NOVICK, a citizen of the United States, and a resident of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Machines for Making Lined Envelopes, of which the following is a specification.

This invention relates to envelope machines angl particularly to that class thereof which is adapted for assembling and folding together an envelope blank and a lining therefor. The object of my improvements is to provide a machine of the class specified which is simple in construction and speedy and accurate in operation. To these ends my improvements comprise features which are illustrated in their preferred embodiment in the drawings accompanying this specification, wherein Figure 1 is a side elevation of so much of an envelope machine as is needed to suitably showmy improvements, the view being taken looking in the direction of arrow 1 of Fig. 3. Fig. 2 is a front elevation looking in the direction of arrow 2 of Figs. 1 and 3. Fig. 3 is a plan view corresponding with the elevations of Figs. 1 and 2, those parts above line AA of Fig. 1 being broken away to more clearly show the mechanism below. All the figures of the drawings are to one scale.

The envelope blanks E are supported in a pile on an elevating device comprising a vertical slide 3 having rack 4 engaged by gear 5 fixed to shaft 6. Said shaft has also fixed thereto worm gear 7 which is driven by worm 8 fixed to shaft 9 turning in bearing 10. To the left hand end of said shaft 9 is fixed ratchetll and which ratchet is intermittently rotated by a pawl not shown. For governing the operation of said pawl, to elevate from time to time the pile of blanks E,

' an oscillating finger 12 pivoted at 13 in upstanding bracket 14 is provided.

The operation of said finger 12 will be more clearly understood in connection with the description herein of the construction and operation of the elevating. and governing mechanism for the lining blanks L, which mechanism is more fully shown and is of the same general character as that provided for the envelope blanks. It will also beunderstood that both of said mechanisms are similar to the showing of United States Patent 1,063,140 issued to- Ferdinand L. May 27, 1913.

Referring now to the elevating mechanism for said lining blanks L, vertical slide 15 has rack 16 thereof in engagement with pinion 17 fixed to the right hand endof shaft 18,

Schmidt,

Fig. 1. The left hand end of said shaftis provided with hand-wheel 19 for hand manipulation. Between gear 17 and hand-wheel 19 ratchet 20 is fixed to shaft 18. Oscillating arm 21 loosely mounted on said shaft carries pawl 22, and detent pawl 23 is pivotally mounted to a fixed part of the structure 111. Pivoted for oscillation in car 24 of arm 21 is arm 25, one end of which carries pin 26 for engagementwith one end of arm 21 and the other end 25 of which is adapted to engage pin 27 of said arm 21. Oscillatingmovement is imparted to arm 25 from cam 28 on shaft 29 through roll 32 on arm 84: fixed to rock shaft 31, and thence through arm 30 fixed to that same rock shaft through link 33 to rock arm 34, fixed to shaft 35. Also fixed to said shaft is arm 36 connected by linkBZ to end 25 of arm'25'. Also fixed't'o shaft 35 is feeler finger 38 for intermittent engagement with the top of the pile of blanks L. The amount of oscillation of the several arms 30, 34:, 25 and 21 is governed by the height of said pile of blanks. When the top of said pile is sufficiently lowered by the successive removal of the blanks, arm 21 is oscillated a sufiicient distance to cause pawl 22 to engage the next successive tooth on ratchet 20, whereby the pile of blanks is slightly elevated. When it is desired to lower slide 15 to replenish the stock of blanks L eccentric lever 39 is turned downwardly, Fig. 2, to free pawls 22, 23 from engagement with ratchet 20,thereby permitting slide 15 to descend. Cam shaft 29 may be driven by means of sprocket'107 fixed thereon and chain 108, from a shaft below not shown. I

The envelope blanks from pile Eare removed one at a time from the top of said pile by the usual vertically reciprocating

pickers

41, 41, and said pickers are caused to adhere to and deposit gum on the uppermost blank by the application of gum to their lower faces by means of reciprocating gum roll 42. Said gum roll, in itstravel to the right, Fig. 2, engages roll 4:3 in gum box Said roll 43 is r tated by means of suitable gearing from pulley 45 driven by belt at from some convenient source of; power on the machine. Said

pickers

41, 41 are reciprocated vertically by lever 47 from a suitable cam on shaft 29 not shown. Gum roll 42 is mounted for free rotation in carriage 48' slidably mounted on

rods

49, 49. Said carriage is caused to traverse said rods by means of

levers

50, 50 connected thereto by

links

51, 51.

Levers

50, 50 are fixed to shaft 52 and one of said levers has outstanding arm 53 which, by means of rod 54, is oscillated from a suitable cam not shown.

After gummed

pickers

41, 41 lift the top blank of the pile to a position just below stripping plate 55, Fig. 2, a reciprocating

carrier comprising slides

56, 56, having hooked ends as 57, reciprocates horizontally to below that top blank. The pickers then ascend a sufiicient distance further to cause the stripping plate to strip the blank from said pickers, and which blank then falls onto said slides and is carried forward thereby from its initial position to position E Fig. 3, ready to receive the lining blank.

To insure the passage of the bottom flap of the envelope blank onto table 90 without catching, bridge 91 having a downwardly inclined receiving edge 92 is provided. Said bridge is mounted to swing horizontally on pivot 93 and is actuated at suitable times from within pocket 95 in table 90 through rod 94 from a cam not shown. To hold the traveling envelope blank down onto

slides

56, 56,

overhead rails

101, 101 are provided. For causing the envelope blank to be properly located at the lining blank receiving station, position E stop

fingers

64, 64. are provided. Said fingers are fixed to shaft 65 which is rocked at suitable times through rod 66 from a cam, not shown, on shaft 29.

To prevent the envelope blank from retracting from position E detent fingers 102, 102 p are provided.

It will be observed that that picker 41 which gums the bottom flap of the envelope blank, is provided with inreaching opposite ears 41*, whereby two inwardly reaching patches of gum are provided onto which to seat the opposite bottom corners of the lining blank. Also if desired the gum on the seal flap of the envelope blank may extend inwardly sufficiently to underlay the V shaped end of the lining blank.

Slides

56, 56 are actuated from a suitable cam, not shown, through rod 58 pivotally connected at 59 to arm 60 fixed to rock shaft 61. Also fixed to said shaft are

upstanding arms

62, 62 connected by

links

63, 68 to said slides respectively.

For delivering the lining blanks one at a time into positionover and onto the successive envelope blanks at position E said lining blanks are picked up from their pile L, at one side of the path of travel of the envelope blanks, and moved transversely to the direction of travel of the envelope blank.

lining blanks and to rise therefrom with the topmost blank.

Said carriage 67 is caused to traverse horizontally on rail 68 by means of lever 71, fixed to rock shaft 72, and which lever is connected to said carriage by link 73. Also fixed to rock shaft 72 is arm 74 carrying roll 75 for engagement with cam 76 fixed to shaft 29, for rocking arm 71. For causing

slides

69, 69 and rail 68 to reciprocate vertically,

rock arms

77, 77 fixed to rock shaft 78 are connected by

links

79, 79 and

ears

80, 80, to said rail 68, and said shaft 78 is rocked at suitable times from cam 81 through roll 82 on arm 83 fixed to said shaft. v

For exhausting the air from suction pickers 70, at suitable times, pump 85 is provided. Said pump may be operated through piston rod 86 from some suitable source of power. not shown. For admitting air to said pump and to thereby cut off the suction from the pickers valve 96 is provided. Said valve may be operated at suitable times by cam 97 acting against valve lever 98. Said cam is rotated from some convenient means, not shown. Flexible pipe 87 leads fromthe upper end of pump 85 to the head of carriage 67, from where

flexible pipes

88, 88 lead to the several pneumatic pickers 70, respectively. Those pickers 70 which lift the pointed end of the lining blank are preferably each provided with a presser-foot 89, for pressing that pointed end onto the envelope blank, when delivered thereover. When carriage 67 is moved to the right from its position of Fig. 2 to a position over the pile of lining blanks, rail 68 is lowered to cause the pickers to contact with the top lining blank of the pile. The air isthen exhausted from the pickers and those pickers rise, thereby lifting the top blank. Carriage 67 then moves to the left, Fig. 2, and the pickers descend and deliver the lining blank in position on the envelope blank as shown in dotted lines in Fig. 3, with those corners of the lining blank adjacent the bottom flap of the envelope in contact with the inreaching gummed portions deposited by gummer ears 41 41 and presser feet 89, 89 press the other end of the lining blank down onto the envelope blank. Pump valve 96 is then opened, thereby admitting air to the pneumatic system and neutralizing the suction in said pickers. Those pickers then ascend, leaving the lining blank in possession of the envelope blank.

The assembled blanks are now ready to be transported to position E over folding box 99. This is accomplished by a second set of

hooks

100, 100 on

slides

56,56 respec tively. As said slides reciprocate tothe right in Fig. 1, stop

fingers

64, 64 are de-, pressed to permit the assembled blanks to proceed on their iournev to the folding box. Also, to assist the leading end of the assembled blanks to pass over the farther edge of the folding box without catching, fingers 109, Fig. 3, having downwardly inclined leading ends, Fig. 1, are projected partially across the folding box. These fingers are carried and operated by lever 110, which is in turn actuated from a cam, not shown, on shaft 29. lVhen said assembled blanks are delivered over said folding box 99 they encounter hooks 103, 103, whereby they are properly located relatively to their direction of travel. Fingers 109. then retract from over the folding box and plunger 104 descends, pushing the assembled blanks into the folding box, whereby the several flaps of the blanks are folded up. The continued downward movement of said plunger delivers the blanks to folding bed 105 where t-he usi al folding wings, as 106, foldthe several flaps, as well known in the art.

Plunger 104 and folding wings, as 106, are

actuated in proper time by means not shown but of well known character.
