SIDNEY A. GRANT, OF SPRINGFIELD, MASSACHUSETTS, ASSIGNOR TO THE UNITED STATES ENVELOPE MACHINE COMPANY, OF SAME PLACE.

ENVELOPE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 432,749, dated July 22, 1890. Application filed October 20, 1888. Serial No. 288,638. (No model.)

To all whom it may concern.-

Be it known that I, SIDNEY A. GRANT, of Springfield, in the county of Ilampden and State of Massachusetts, have invented a new and useful Machine for Making Envelopes and the Like, of which the following is a specification, reference being had to the accon1- panying drawings,in which- Figure l is a plan of one form of machine embodying my'invention, the greater part of the endless drying-chain with which my machine is preferably provided being removed for greater clearncss. Fig. 2 is a front elevation with parts broken off. Fig. is a rear elevation with parts broken off. Fig at is a vertical section on line 4 4 of Fig. 1. Fig. 5 is a vertical section on line 5 5 of Fig. 1. Fig. 6 is a side elevation, partly in section. Fig. 7 is an elevation of the side opposite the side shown in Fig. (3. Fig. 8 is a sectional view of the creasing and gumming cylinders, and shows also a port-ion of the frame in which these cylinders are mounted. Fig. 9 is a section of one of the cylinders, showing it arranged to carry a type-plate. Fig. 10 is asection on line 10 10 of Fig.8.

My invention is an envelope-machine which simultaneously creases and gums (and, if desired, prints) the envelope-blanks, one object of my invention being to produce machines of this sort which may be attended to in practice by unskilledor youthful attendants.

The features of my invention will be pointed out and claimed hereinafter.

While I prefer to use a slight projection on one cylinder and a slight depression on the other, it will be clear that a slightridge forming a rectangular figure upon one cylinder and a slight groove forming a corresponding figure on the other cylinder will answer. I have tried both forms,but prefer the former, the only advantage of the latter being that the slight ridge forming the rectangular figure will make its own groove on aroll whose surface is sufiiciently yielding.

In the drawings, which show one form of machine embodying my invention, (beingthe best form now known to me,) the device by which the blank is creased is made up of cylinders A A, one of the cylinders being provided with a land a and the other cylinderbeing formed with a depression (0 adapted to receive the land, so that when the blank is pressed between the land and its corresponding depression creases are formed by the cornets of the end and side walls of the land on the blank. Cylinder A is also shown as provided with gummers a, which are formed to correspond to the margin which is to receive the gum, and are conveniently supplied with gum by the gum-distributer a taking gum from fountains a Foldingbed B receives the blank after it passes from between the cylinders A A, the blank being fed positively to the folding device, which may be of any suitable construction, but is preferably made up of the table B, folders I) b for the end flaps, and folder I) for the back flap. The folders I) Z) W are actuated to fold the creased blank, and in the preferred form of my machine the positive feed of the blank from. the gumming and creasing device to the folding device is ac complished not only by the creasing-cylinders,but also by the auxiliary disks a One important feature of my construction is the combination, with a device for folding the end and back flaps, of a presser-foot, which, in the preferred form of my machine, not only holds the blank on the folding-bed while the end flaps are being turned, but also presses the back flap after it has been folded firmly on the underlying end flaps. This presser-foot is marked B.

The envelope is moved positively out of the folding device by means of the reciprocating pusher B which engages an edge of the envelope and shoves it off the folding-bed.

I prefer to feed the completed envelope from the folding device to a drying-chain D, 0

the operation of which is hereinafter eX- plained, and from the drying-chain the cue velope is fed positively into a receiver R.

In the form of machine now shown, motion is communicated to cylinder A from main shaft F through gears ff, shaft f disk f rack f pinned thereto, guarded in boxf and meshing with pinion f on shaft The cylinders A A are each provided with a pinion f and these pinions mesh together, sothat the rotation of cylinder A rotates cylinder A, which is mounted on shaft f mounted in a bracket F, arms f of which are provided with eccentrics e e, (seeFig. 8,) so that when the bracket is rocked in one direction cylinder A is moved away from A, and when rocked in the other direction is moved toward cylinder A. The bracketis rocked by means of forked rod f pivoted to an ear f of bracket F and projecting toward shaft f, on which a cam f (see Fig. 4) is mounted. Forked rod f provided with roll f, co-operates with cam f to move cylinder A, away from cylinder A. The bracket F is moved in the other direction by a springf Cylinders A A are closed to engage the blank to crease and gum it, and when the blank is fed out of them are separated, so that the gummers do not come in contact with the companion roll, and they are held apart until it is time to feed another blank-that is, until the folding operation is sufficiently advanced to make it practicable to feed another blank, and for this purpose I employ the dog f which is controlled by a treadle f Dog f is pivoted to the frame of the machine and is moved out of the way of the bracket F by pressing down on the treadle f and is returned into position under the bracket F by a spring f (a portion of which is shown in Fig. 6,) the foot being then removed from the treadle f The rotation of cylinder A rotates the gum-rollers through gears f f' ,f and f. f is a doctor for the gum-roller. The cylinders A A arranged as shown in the drawings, have a function as feed-rolls, but the feed from the c linders to the folding device is accomplished mainly by the disks a above referred to, and from these disks the blank is guided to the folding device largely by the disks b cooperating with corresponding disks b the disks 5 being mounted on arm 5 loose on cross-rod Z). Disks b are mounted in the frame of the folding-bed B and are driven by gears 11 one of which meshes with a gear on one of the feed-rolls a which is driven by gears meshing with a gear on cylinder A. (See Fig. 4.) Rockerarm b is moved bylink b connecting the rocker-arm with rocker-1ever 1)", loose on shaft 1) and actuated by connecting-rod D and the cam Zon shaft f the rod b having a roll? to engage the caml against the force of a spring I), secured at one end to the frame of the machine and at the other end to connecting-rod b When the blank is fed into place on table B, the folder I) is moved to engage an end flap and turn the end flap on the main portion of the blank. Motion is communicated to the folderb through link Z9 connecting the folder I), which rocks on shaft 19 to an ear on the folder 11 as indicated in dotted linesin Fig. 4, and this car on 11 (see dotted lines in Fig. 4) is connected by rod Z9 to a cam on shaft f the connecting-rod being provided with a roll 3, engaging cam 4, and being moved in one direction against the force of spring Z) and being moved in the other direction by the spring I), as will be readily understood without further description by reference'to Fig. 4;. The movement of folder 1) thus combined with folder b folds the end flaps of the blank, the blank being held on the bed between the friction rolls b and rolls b and also by the presser-foot B, which descends to clamp the blank upon the table B by the rocking of shaft Z)", which is rocked by means of cam-rod 1), fast to rocker-arm 5, and a cam 00 (shown in the dotted lines in Fig. 6) on the face of gear f, the rock-shaft being rocked against the force of spring I), by which it is return ed to place at the proper time. Rocker-arm 5 is provided with a roller, (see dotted lines in Fig. (3,) which works with the cam 00. (See Figs. 6 and 5.) The back-flap turner b, by means of which the back flap is folded, is moved to fold the back flap by the pusher 12 mounted in rack I7 meshing with pinion W mounted on shaft Z1 which is provided with a pinion b meshing with rack 19 which is reciprocated by means of a cam on the face of rotary disk f mounted on shaft f As pusher b moves inwardly, it moves the back-flap turnerb' on its rock-shaft 1) against the force of springs with which that shaft is provided, the shaft being journaled in a recess in the folding-table B. The presserfoot B, which was lifted to allow the proper motion to flap-turner I), now descends, as above explained, and is afterward lifted by the rocking of shaft Z)" in the other direc-.

tion. Rocker-arm and the friction-disks b carried by it, are also lifted to allow pusher ISO 5 to move over the folding-bed and push the on rod Z7 and is rocked in the other direc- I tion by spring 12 with which cam-rod b is provided,) rides up the turner 19 which is rocked to bend the sealing-flap along the line of its crease over toward the body of the envelope as the envelope is pushed along under the turner Z7 and off of the folding-table by the continued forward movement of the pusher b \Vhen the drying-chain D is used, the envelope is pushed off the foldingtable into the chain, the members d of which open to receive the envelope and thenv close to carry it to the receiver R, the chainD being mounted on a roll d and a sprocket (1 as will be readily understood by all skilled in the art, the shaft of the sprocketbeing provided with ratchet (Z with which a springcontrolled pawl d mounted on arm (1 co-operates. Arm (1 is rocked by connections c G d and crankpin (1 rotating with shaft f When the envelope has been carried into position for removal from the chain, it is seized by fingers 1", working in the chain, the members dof which loosen their grip on the envelope, as will be readily understood by those skilled in the art. When the envelope has reached the said position, the fingers are actuated by the rockerarm 0", fast-to rocker shaft 0*, to pull the fingers downwardly against the force of spring T and thereby to pull the envelope from the chain into the receiver R. Rocker-shaft "r is rocked to accomplish this, and is provided with an arm r connected by red o to an arm 0' mounted on shaft 0 the arm 0' being adapted to engage the cam 1' on shaft f Receiver R is provided with a follower R, which is moved in the receiver R by means of a rocker-arm r mounted on shaft Wand actuated by cam 9*. The receiver R is also provided with a spring-controlled guard R and with stationary guard R Gear f of cylinder A meshes with gear a which meshes with a gear a on ink-roller T, on which the ink distributing rolls t rest. Ink is supplied toinkroll T by a roll t, which comes in contact at proper times with ink-roll 25 rotating in fountain T, the shaft of inkroll 75 being provided with a ratchet 25 which is engaged by a pawl 29*, mounted on arm '6 which is connected by alink if to an ear of the flap-turner b the movement .of which flapturner causes the arm i to move, and thereby to rotate the roller 15 in the ink-fountain. The roller t, which is intermediate the ink- .roller T, and the roller 25*, which rotates in the fountain, are reciprocated between the two rollers, and are accordingly mounted in a bracket 15 which is rocked on shaft i by an arm t", controlled by a cam 15 arm 25 being provided with a roll. In order to secure a thorough distribution of the ink on the inkrolls, it is desirable to reciprocate one or more of them endwise, and in the machine shown the shaft of roller T is provided with a grooved hub i in the groove of which is placed a finger t, which engages cam 9 on disk f hen it is desired to print the envelope, the cylinder A is provided with typesay an electro-typeA which is preferably mounted on a reciprocating carrier a so that the typeplate is in position to print when the block is in its lowest position. The reciprocating carrier a is mounted in the cylinder A, and is moved to move the type-plate into position to be inked by cams a on the shaft of the cylinder. The carrier at is moved against the force of springs c0 and when the cams a are in their inoperative position the carrier is returned into the position shown in Fig. 9 by the springs a. The shaft of cylinder A is journaled in the arms f of bracket F, the eccentrics, e of these arms fitting in bearings a, mounted in the frame of the machine. The bearings c0 and the bearin s a of the shaft of cylinder A are mounted in an opening a, and adjusting-screws a are provided for regulating the space between the two cylinders, as will be readily understood from reference to Fig. 8, this regulation being to fix the cylinders at any desired distance apart, and being wholly independent of the movement of the cylinders in relation to each other with stop-guides a, which prevent the insertion of a blank between cylinders A A, except at the proper time, the guides d being mounted on a leaf-spring a and projecting above the upper surface of the table in front .of the rolls, except when depressed by the cross-bar of bracket F striking pins (1 The operation of that form of my machine shown in the drawings is as follows: Starting with the rack f", bracket F, and stops (0 in their highest positions (see Figs. 2, i, and 6) motion is imparted to shaftf from main shaft F and to disk f rotating with shaft f and carrying rack ft As the rack descends, meshing with pinion f, it carries the disk 9, which is fast to the pinion, and the pawl 10, mounted on the disk, into the position shownin Fig. 7, and when the rack begins its upstroke the pawl 10 engages the' toothed disk 11, fast to shaft f thereby rotating cylinder A and compelling the rotation of cylinder A and parts connected therewith. The blank is presented by the attendant and properly gaged by the stops a, one of its flaps projecting between the cylinders A A but these cylinders are kept apart by the dogf until that dog is drawn away by the operator by means of treadle f when the bracket F is pulled down byits sprin g f therebybrin gingthe cylinders A A together and nipping the front flap of the blank between them and also depressing the stops (L18, the rolls A A being at this time stationary. The blank is carried through the cylinders and fed by them positively to the auxiliary feed-disks a, (which, together with the gum distributers, are driven simultaneously with the cylinders A A, as will readily be understood from what has been said above,) and the auxiliary disks a feed the blank to the disks b b, which guide and help feed the blank to the folding-table B. The feed begins when the rack f is in its lowest position and continues during the upstroke of the rack f so that the cylinders are intermittently rotated, thereby giving time to the attendant to put the blank in place to be seized by the cylinders A A. As the rack f begins its upstroke, the pusher 19 drawn back into the position shown in Fig. 5, and the end-flap turners h b are moved back out of the way of the blank which is being fed to the folding-table B. hen the pusher has completed its backstroke, the back-flap turner Z) is open thatis, thrown into the position shown in Fig. 5 by its springs. As the blank thus gummed and creased by the cylinders, and also printed, if desired, is fed forward on the foldingt-ablc, the arm bfl which carries the friction-disks b descends to bring the disks in place to co-operate with the under disks b and thereby guide the blank into place on the table B. When the blank has reached its proper position on the table, the feed ceases, because the rack f then begins its downstroke and the presser-foot B descends. As the presser-foot moves down, the end-flap turners b b move simultaneously to fold the end flaps of the blank, the end flaps being supported previous to folding by fingers projecting from the table. The presserfoot B holds the blank in place while the end flaps are being turned. WVhen the end flaps are folded and while the end-flap turners are yet on the blank, the presser-foot B rises sufficiently to allow the pusher 17 to turn up the back-flap turner b and fold the back flap over in place on the end flaps. The pusher b rides over the back-flap turner, lingering thereon, while the presser-foot B descends on the flap-turner b, and thereby presses the gummed flap firmly in place on the end flaps folded underneath. The arm b carrying the friction-disks 17 now begins to rise, and the end-flap and back-flap turners and the presser-foot move away from the folding-table nearly simultaneously, and the pusher, with its fingers 12 in grooves 13in table B, begins to push the envelope toward the drying-chain. The seal-flap turner 1) now rises, the seal-flap being carried over the sealfiap turner by the forward motion of the envelope until the turner finally brings the sealfiap into position. The seal-flap turner is formed with a passage (see Fig. 5) for the pusher to allow the pusher to move through it and push the envelope into the dryingchain.

As the pusher forces, the folded envelope into the drying-chain and before it is moved back, the rack f reaches its lowest position, thereby bringing the cylinder into position to feed another blank.

What I claim as my invention is 1. In an envelope-machine, the cylinders A A, in combination with folding mechanism, one cylinder having a land a and the othera depression a to make the four creases between the fiaps and the body of the envelope, substantially as and for the purpose set forth.

2. In combination with the cylinders A A, one having a land a and the other a depression a and actuating mechanism to intermittently rotate the cylinders, stop-guides c11 and means, substantially such as described, (for example, bracket F, pins a and springs a for varying the position of the stops, the stops when in one position preventing the insertion of the blank between the cylinders and when in the other allowing the insertion of the blank between the cylinders, all substantially as and for the purpose set forth.

3. In combination, creasing-cylindersA A, one having a land a and the other a depression a gummers a, and gum-distributer a the guinmers being mounted on creasing-cylinder A substantially as and for the purpose set forth.

4.

5. In combination, feed-table A reciprocating stops a, and creasing-cylinders A A, one of the cylinders having an intermittent motion toward and from the other cylinder, and mechanism for depressing the stops a, and folding mechanism, all arranged and operating substantially as and for the purpose set forth.
