Application filed March 31, 1921. Serial No. 457,377.
To all whom it may concern:
Be it known that I, ABRAHAM NovIoK, a citizen of the United States, and a resident of the city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in a Machine for Making Window Envelopes, of which the following, together with the accompanying drawings, is a specification.
The present invention relates to a ma-- chine for making window envelopes, the latter being the type of envelope which provides an opening, usually covered by a transparent patch, in the face thereof, so as to reveal the address on the enclosure.
The invention resides in a novel combination'and arrangement of elements which are designed to facilitate, and render more secure, the application to the successive envelope blanks in process of manufacture, of the transparent patches or window coverings, all as more fully set forth in the following description, reference being had' to the accompanying drawings, in which-.-
Fig. 1 is a side elevation of a window envelope machine embodying the improvements, with a part of the frame broken away.
Fig. 2 is a front elevation of said machine. Fig. 3 is an enlarged sectional view of the patch applying mechanism, the section being taken on the line 3-3 of Fig. 5.
Fig. 4 is a view similar to Fig. 3, the section being taken on the line 44 of Fig. 5, and showing the patch applying mechaupp'er machine nism in a difi'erent position.
' Fig. 5 is a front elevation of the mechanism shown in Figs. 3 and 4.
Fig. 6 is a horizontal sectional view on the line 6-6 of Fig. 5.
Fig. 9 is a plan view of one of the envelope blanks, illustrating the application of moist gum thereto,. preparatory to the ap lication of a transparent patch.
ike reference characters refer to like parts in the diiferent figures. The fixed framework of the machine rovides vertical slideways 1, 1 for a b ank table or support 2, the latter adapted to sustain a pile orvstackof blanks 3 which may be of the shape and configuration .For. applyin ,ming and pic ing device 4, the machine proshown in Fig. 9, or any'other. desired shape. Said blanks are adapted to be removed, one by one, from the top of the stack 3, andin common with machines of /the same class, the machine of the resent invention provides suitable elevating mechanism, operated automatically, for procuring an upward feed for the table 2, in order to main tain the top of he stack 3 in position to be operated upon by the blank removing means, as hereinafter described. Said automatic elevating mechanism, of any well known type, is not specifically shown or described herein, since it forms no part of the present invention. I
' The successive topmost blanks of the stack 3 are operated upon by a suitably constructed gummingand picking device 4, the latter being carried by.a rod 5 which travels in brackets 6, and being actuated by a cam 7 on the main shaft a of the machine. Said cam 7 operates a push rod 8, the latter being connected to a lever 9011 a rock shaft 10 which provides a link connection 11 with the rod 5. The reciprocating gumming and picking device 4 presents a plurality of suitably disposed gumming dies on its under 'surface, so arranged as to contact with. theblank, along its edges, and around the cut-out window thereof, in the manner indicated by the shaded areas on Fig. 9. adhesive to the dies of gum vides a travelling gum roll 12, which, at one end of its movement, makes contact with and receives gum from a suitable gum transferring roller 13, the same being mounted in a gum box 14, of ordinary construction. The supports 15 of the travelling roller '12 move back and forth on horizontal rods 16, in order to bring the travelllng roller in contact with the dies on the bot-" tom of device 4, when the latteris in raised position; to this end, any suitable means may be employed for reciprocatm the su ports 15, as for instance, thell s 17, 1 connected to hell cranks 18, 18 and actuated from the main shaft by the typical cam and push rod arrangement which is shown in Fi 8.
The contact of the gummed surfaces of reciprocating picking device 4 with the topmost blank of the stack 3 causes the separation and elevation of said blank on the upward movement of device 4, the blank being rod 24 from an eccentric 25 on themainshaft a. The return movement of the arms 20 is such as to carry the ummed blank partly across the creasing p ate 26 of'the machine, as indicated in Fi 3 and 4, the advancing ed e. of said blan being squared and registers by contact with a pan of stop fingers 27, so disposed that the cut-out window portion'of the blank is superposed upon a ledge'or extension 28 which hes adjacent to the. rectangular aperture 29- of creasing plate- 26. t
A blank thus brought to rest upon the creasing plate 26, and rearwardly of the osition which it occupies when acted upon y theusual creasing plunger, is 1n readiness for the application of the transparent atch thereto; the window aperture of the lank, with its. margin of moist gum, is superposed uponthe firm support provided by extension 28, As herein 'shown, the transparent patch material is taken from a roll 30, and is fed by means of automatically operated feed rollers 31, 31, the latter being geared together for rotation in unison, by means of gears 31, one of which is shown inFig. 7. For operation of the rollers 31, 31, the machine provides a sprocket chain 32 connecting the sprocket 33 on the main shaft a withia sprocket 34 on a shaft 35. Gears 36 and 37 transmit rotation of shaftto the shaft of upper feed roller 31.
' The web of'patch material is projected by the feed rollers 31, 31 between suitable guide devices 38, 38, the latter directing the material to the cutting "mechanism which comprises stationary and movable knife edges 39 and 40'. The action of this mechanism is as follows :Patch material is projected downwardly and forwardly ,ast thecooperating knife ,ed es' so that it's ree-end covers the surface 9 pivoted hollow member 41, which-provides a plurality of suction openings 42. The latter, communicating with the interior of said member, are connected bya pass e 43 to a hollow trunnion shaft 44, by whic said member 41 is supported. The trunnion shaft 44 isconnected by means of a flexible tube 45, Fig. 7, to a vacuum ump 46, Fi 2, the latter being operated y any suita 1e cam and push rod arrangement from the main shaft 1, such as the arrangement shown in Fig. .8. Theoperation of pump 46 so tiined as to create a partial vacuum in the member 41 coincidentwith the arrival of the patch material in position "to be acted upon by the suction holes 42; thereupon, with the patch material held firmly in place by the vacuum,-
' gummed window opening. The knife edge .40 is actuated. by a cam 47 on shaft 35,
which works against a roller 48 that is carried by an arm 49 on a shaft 50. The arm 51, projecting downwardly from the shaft 50, is suitablyconnected to the .knife edge 40 to actuate the same when said shaft 50. is rocked, said arm being acted upon .by a spring 52 which maintains the roller 48 against the cam 47.
v pon the severance of the individual patch from the web of material as above described, the member 41, against which said patch is held7 by vacuum, is adapted to be rocked or swung about its hollow trunnion end of an arm 55 which is carried by a shaft 1 56. The shaft 56carries a suitable bell crank lever 57, one arm of which is connected by a spring 58 to the fixed framework,
With the patch thus applied, the blank is in condition for the usual creasing and folding operatidns, but before these operations are commenced, said blank must be moved outwardly on the creasing late 26 so as to bring its several lines ,of f0 d, indicated by dotted lines in Fig. 9, into registry with the edges of the rectangular opening while the other arm provides aisegmental 1 shaft 67 constitutes the rocking pivot of lever 23, and consequently insures the movement of stops 27 'for a part of the stroke of arms 20, 20, there being no movement of said stops 27 when the concentric portion of the cam 66 is in contact with roller 65.
In this way, the blank with the patch aplied thereto, as above described is carried ack the requisite distance so as to register correctly with the rectangular opening 29 of creasing late 26. Thereupon, as the arms 20 and hoo fingers 21 continue their outward movement, on the way to the seizure of the next blank, the creasing plunger 68 descends, and forces the patched blank lying on the creasing plate through the o ening 29 and against the bottom of the usua folding box 69. The plunger 68 is carried by rod 70 and is reciprocated in the usual manner by means of levers 71 and 72, the latter bein pivoted at 73 and operated by a push ro 74 which is driven from the main shaft by the typical cam arrangement shown in Fig. 8. In the folding box 69 the creased blank is seized by suction exerted throu h holes 7 5 in the bottom 69' thereof, these oles communicating with a vacuum chamber 76 that is connected b tubing 77 to an air pum 78. The usual si e flap folders '79, 79 an the seal and bottom flap folders 80, 81 function in the ordina we to turn down the upturned flaps o the lank, bein actuated by links and rods 82 and 82' that erive motion from the t ical cam arrangement shown in Fig. 8. e completed envelopes are discharged from the folding box by the downward movement of its bottom 69', swinging about the pivot 83. At this moment, the air suction in the chamber 76 is released, to permit the completed envelope to drop by gravity into one of the com artments of a chain drier 84, the latter de 'vering successive formed envelopes upon a platform 85 which, in the usual way, transfers them to the delivery table 86 of the machine.
I claim,
1. The combination with the .apertured creasing plate of an envelope machine, of means for conveying successive apertured blanks thereto, means for pressing a trans- 6 parent patch onto each blank, to cover the aperture therein, while said blank is resting on said creasing plate, and means for thereafter reversing the movement of each blank to register it with the aperture in said creasing plate.-
2. In an envelope machine, the combination with the usual apertured creasing late and creasing plunger, of a patch app y ing and pressing mechanism constituted in, part by an extension of said plate, means for first subjecting apertured blanks to the action of said patch applying. and pressing mechanism, .and means for thereafter reversing the movement of each blank to reg- .isterit with the aperture in said creasing plate and with said plun er.
3. In an envelope mac inc, the combination with the usual apertured creasing late and creasing plunger, of a patch app ying and ressing mechanism, and a reci rocating blan conveying means adapted y movement in one direction to subject each blank to the'action of said patch ap lying arid pressing mechanism, and adapted ment in the other direction to register each patched blankf with the aperture in said V creasing plate and with said plunger.
4. Ina machine for making window enby movevelo es, the combination with picking 90 mec anism for applying adhesive to the flaps and window margin of a blank, and creasing and folding mechanisms for said blank, of a patch applying mechanism .in
line with the movement of said blank from said picking mechanism to said creasin and folding mechanisms, said patch app ying mechanism being operable on said blank beyond said creasing and folding mechanisms.
