MACHINE FOR MAKING AND PRINTING ENVELOPES.

SPECIFICATION forming part of Letters Patent No. 463,981, dated November 24, 1891.

Application filed March 18, 1891. Serial No. 385,543. (No model.)

T all whom it may concern:

Be it known that I, JAMES BALL, a citizen of the United States, residing at Holyoke, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Machines for Making and Printing Envelopes, of which the following` is a specification.

This invention in machines for making and printing envelopes particularly relates to improvements in the gumming mechanism for the glimmer-pickers, in the ink-distributing devices for the type, and in the bed on which the printed and gu mined envelope-blanks are to be folded and from which they are to be discharged.

The improvements in thev gumming meehanism are to the end of securing one which due to the improvementsin theink-distributing devices, the latter are rendered unusually advantageous for their efcient action; and to the ends as above indicated the invention consists in the construction and combination or arrangement of parts, all substantially as will hereinafter more fully appear, and be setforth in the claims.

Reference is to be had to the accompanying drawings, in Which such illustrations of the present invention are given as, in connection with the following particular description, will readily disclose to persons skilled in the art the composition and operation of the mechanism of the present invention.

Figure l is a sectional elevation, taken from front to rear and about centrally, of a machine for making and printing envelopes. Fig. 2 is a horizontal section and plan view of the same. Fig. 3 is a front elevation of enough ot` the machine to include and illustrate theimprovements in the gumming mechanism. Fig. Ltis a view in perspective on a larger scale,

Y illustrating some of the mechanism eoacting with the movable folding bottom. Fig. 5 is a perspective view, also on a large scale, in illustration of parts of the inking mechanism.

Similar characters of reference indicate corresponding parts in all the views.

The envelope machine Will not be described, except as to the particular features of the present invention, f urther'than to state that the blanks are supported and automatically elevated into the right relation to the gummer-pickers B on and'by the table A. The blanks are then taken upon the conveyor C and carried to the action of the printing machinery, the type bed being indicated at D and the platen at E, both being movable to and from each other by suitable mechanism, as is common or desirable. The blanks are successively farther rearwardly conveyed, after being printed, to the creasing-box F, being forced therethrough by the plunger G onto the novel folder-bed H, and then the iiaps are folded down by the folder Wings, (slightly indicated in dotted lines in Fig. 1 at Cn) after which the bed is tilted to permit of the envelopes falling or being discharged into the drier-ehain.

The novelty in the gumming mechanism consists, primarily and essentially,in the combination, With the gummer-picker having the usual reciprocatory movement, of a gum-box having a gum bearing or supplying surface or member located at one side of the line of the pickers movement, and a pair of rolls and a suitable carrier therefor for moving said rolls, so that both thereof Will roll over the face of the picker-gummer, the one roll in advance of the other, and one of said'rolls Will be periodically movedto a bearing With f the said gum bearing and supplying surface or member. Said gumming contrivance,hw

with their axes at right angles to their movement of traverse from the one gum-box to the other, said rolls being mounted with the upper portions of their peripheries in the same horizontal plane and coincident with the face of the gummer when the latter is in its uppermost position, on suitable bearing-supports l), which are mounted and guided on the runner-rods o,which latter are horizontally ranged at the front and to the rear of the glimmer. The traversing motion of the said rolls is insured at each time that the guminers B B dwell momentarily in their uppermost position by having the link or connecting rods e e each attached by its one end to one of the roll-supports l), each of said connecting-rods by its other end being connected to an arm g on the rock-shaft K. The rockshaft receives its rocking movement through means of connections and parts intervening between same and the cam 7L on the shaft I, (which shaft is suitably geared to the driving-shaft J,) which parts and 'connections consist in the intermediate rock-shaft t', having the two radial arms j and j', the radial arms 7c on the rock-shaft K, the link Zbetween arm 7" and arm k, and the tlirust-rod n, receiving a reciprocatory motion in a usual manner from the cam h, and having by its upper end a connection with the said arm j.

ln the running of the machine, while the picker-gummers B are rising, the pair of guinming-rollers ff are at either the one side or the other of the gummers resting by the one of said :rolls f which is then farthest from the guminers on the roll d of the gumbox, which is off at such side of the guin- As is well known under the ordinary modes of gumming, as the blank raised by the gummer-picker is detached therefrom the surface of the gummer from which the blank has been forcibly strippedis left lumpy or liubbly, for as the blank is detached it draws a portion of the gum, which is not taken up by the blank, but remains on the gummer down from the face of the glimmer to remain as an uneven surface onto which the next coating of gum is usually applied by the freshly-supplied roller. Now it will be seen that under the present improvements the one of the rolls f which next rst passes over the face of the elevated glimmer is the one which had last run over said face and imparted the gum thereupon, and therefore the said roll (running in advance of the one of the rolls f which had last rested on the gum-box roll and which is plentifully supplied with gum) smooths down the gum on the face of the gummer, so that the other and fully-gummed roll following closely behind spreads its gum upon a smooth and even gummer-face, so that consequently the flaps of the envelope will be correspondingly evenly and completely gummed.

Iam aware that it has been proposedin the' gumming of the gummer to pass a single roll from one gum-box with gum thereon past and upon the gummer, and thence to the other gum-box to receive gum for supplying the gummer on the return movement of the roll over the face of the gummer. This method of gumming is devoid of the advantage arising from the smoothing-down roll, which is alternately constituted by the one or the other of said pairs of rolls when the pair is used as set forth under this invention. Another feature of practical advantage arising out of the saidimproved mechanism consists in the fact that each one of the rolls f contacts with but one of the gumbox rolls cl. In practice where a single roll has a shuttle motion between the opposite gum-boxes, the effect, unless great care and intelligence was observed in adjusting the parts regulating the gum delivery, was that the reciprocating roll will receive an overplus of gum from one roll and would infact deposit gum onto the roll into the other box, which latter instead of becoming depletedwould in fact become excessively tilled with gum at the expense of the opposite gum-box and also of the satisfactory gumming action upon the `pickerguinmer. Any such undesirable action is of course rendered impossible under the mode of procedure consequent upon the present provision and arrangement of the parts.

Describing now the improvements in the ink distributing devices for the printing mechanism ot' the machine, L represents an endless apron, which is mounted horizontally upon the two shafts or rolls l0 10, which are ranged in parallelismbehind the printingbed `D with their axes extending from front to rear of the machine, as will be understood on reference to Fig. 2, and so that as one of said rolls l0 is turned the said endless apron L will be moved to present dilferent portions thereof back of and in line with the said type-bed.

M represents an ink well or supplylocated at one side of the machine, which is of an ordinary construction and is arranged above and in relation to the ink-carrying roll l2, so as to impart to said roll suitable portions of ink from time to time, as is demanded. The said roll l2 is supported and guided for a horizontal movement on horizont-al runnerrods 13 13, and a back-and-forth movement is imparted to the said roll l2, so that it may, receiving ink from the ink-supply M, convey ink to and upon the endless apron and then return to its position under the ink-supply.

Such back-and-forth movement of the roll 12 is secured through the connecting-rods lll 14, which are united with the radial arms l5 l5 upon the rock-shaft K. p represents a distributing-roll, and q represents an ink-roll for the type-bed, and the said rolls p and q are united to move in unison, the one p across the upper surface of the endless apron onto the receiving-roller r, which receiving-roller is just in advance of the forward edge of the said endless apron and has a position under the roll q when said roll is in its normal posi- IIO tion, and the said roll q. (as the roll p moves as just above described) moves forward upon and across the face ofthe type. The face of the type, when the type-bed is in its lowermost position, is in a plane which is coincident with the under surface of the said inking-roll q. The ink-receiving roll r has its arbor r extended to the side ofthe machine,

as shown in Fig. 2, and is there provided with to a pulley upon which to belt for the rotation of said roll from any shaft or rotatable part of the machine. The endless apron L is given a step-by-step movement by means of the pallet 19, which is pivotally mounted on the I5 radial arm 20, that is loosely supported on the axial stud 22 of one of the rolls 10 with the ratchet-wheel 23, which is fixed upon the end of the said roll 10. A reciprocatory movement is imparted to the pallet-carrier 2O by I zo the connection therewith of oneend of a connecting-rod 24, which by'its other end has an engagement with a radial arm 1'5 on rockshaft K. The concurrent movements of the rolls p and q from rear to the front of the z 5 machine and return is secured through means of the connection with the arbor of the one or the other of said rolls, or with the rigid tie-pieces which unite them, of the link 26, which by its other end is pivoted to an arm 3o 27, affixed to and radially extended from the pivoted on the frame and swung by the cam 33 in one direction, said arm 32 being swung in the other by the retracting-spring 34. The said rollers p and q are supported and horizontally guided upon the runner-rods 35, sub- 4o stantially as shown in the drawings, Figs. l

and 2.

Vhile the operation of the mechanism above described is undoubtedly apparent without further description or explanation, it will be Y briefly mentioned, however, that the roll l2 conveys ink from the ink well or supply M to and upon the endless apron L, above one of the rolls l0. The said endless apron has a stepby-step movement, so that the inked portion 5o thereof has a suitable traverse and is brought in the line of the run of the distributingroller p, which, in addition to effectinga complete and even distribution and spreading of the ink upon the endless apron, also conveys 5 5 portions of the ink therefrom to and upon the receiving-roll i, and the roller q periodically carries the ink to and inks the type.

The endless apron L described is in itself a novelty of much utility, especially in a ma- 6o chine substantially such as the present one,

and the said endless apron consists of a belt 37, of canvas or other textile material, or, in fact, any suitable flexible material, and a comparatively thick layer ,e of the ordinary printers roll composition, which is placed evenly and uniformly upon the said belt 37, having an engagement therewith by the permeation of the interstices ofthe said belt material.` This endless apron is very tough and elastic, unusually durable, and permits of the advantageous'employment of an ink-receiving apron, where otherwise inconvenient expedients would necessarily have to be resorted to to accomplish the results here attained. v

The bottom H, on whichthe gummed, printed, and creased envelopes are foldedconsists of a long slab having an upper plane surface which is horizontally about coincident with lthe upper surface of the main table m of the machine, and said surface has alength which is a number of times as long as the length or width of lthe envelope to be folded thereon, the said slab being transversely supported upon the carrier N. The said carrier N is provided with a dovetailed way 40, in which the said slab H is free to move, and the movement of the said slab transversely of the machine is to be imparted so that at each envelope-forming operation of the machine a fresh surface on which to fold may be presented by any suitable mechanism, a form of m'echwhich is mounted upon table :cadjacent thev said slab for rotation with its axis horizontally. The said friction-drum 52 has 'on one side thereof a ratchet 53, having double-facedteeth, substantially as shown in Fig. 4.

54 represents a lever intermediately pivoted, as at 55, carrying upon its upper arm the pivotally-hung double-toothed pallet t, which is provided with the extended and weighted arm 5G. The tendency of the Weight upon the pallet is to maintain the same,k

whether the lever-arm carrying same is tilted forward or back, so that when once swung to present one of the pallet-points 60 into engagement with one set of faces of the doublefaced ratchet-wheel 53 continuously in such engagement, the opposite pallet-point being then of course swung out of engagement with the other set of faces of the said peculiarlyformed ratchet-wheel, the lever 54 receives its swinging motion through the connection with the lower end of the same of a radial arm 62, atlixed on the before-mentioned rockshaft K. Y

lVithv particular reference to the perspective view, Fig. 4, it will be apparent that at each swinging movement of the lever 54 the ratchet 53 and drum 52 will be partially. rotated in the direction of the arow 7, and said drum having its axis immovable and cord 50 being under tension around the drum will insure the movement of the slab in the direction of the arrow 8, and this direction of feed IOC IIO

ot' the slab II will be continued under the running of the machine until the pallet t is reversed, so as to insure the working of the ratchet-wheel by the engagement of the other pallet-point. The reversal of the run of the slab, after it has been brought to present a portion thereol:` which is near its end to the folding position of the machine, is to be automatically effected, various eontrivances for which purpose may be employed, and they are within the range of knowledge of skilled mechanics; but-I have here illustrated one iorm of means forinsuring the reverse movement of the slab, which will be now described. At each side of the axis of the Ydrum and ratchet 52 53 are provided levers u u, which by their bottoms are pivote-d upon lugs G4: that are formed on or secured to the top of the table of the machine. Said levers are provided with limiting toe-pieces 65, so that each may be normally under the tension of the spring 66, which is applied thereto, held in the inclined position substantially as shown. Each of said levers u is provided with an eyeformed member 67, through which the portions of the said cords 50 which are extended from either side of the drum 52 loosely pass. The said levers u are formed at their extremities with extensions (SS, which extend across the plane of swinging movement of the double-pointed pallet t. The cord 50 at its portions that are suitably near the ends of the slab H has the dogsorbuttons 69. (See Figs. 2 and 4.) Now, noting Fig. ft, it will be seen that after the slab has been moved a short distance beyond the position in which it is shown, in the direction of the arrow 8, the right-hand dog orbutton 69 on the cord will come to an engagement with the member (57 of the level' u, which is at the right of the drum and ratchet. The said lever fu, will consequently be swung against the spring 66, insuring the tilting of the pallet, so that the same works by its other tooth, securing, withouty any change in the swinging movement of the pallet-carrying lever 54C, a reversed rotation of the drum and ratchet-wheel, and consequently a reversed rectilinear movement of the slab ll. At the completion of each envelope-foldingoperation the carrier N, and with it the said slab H, is swung downwardly, so that the slab occupies a position more or less nearly like the one indicated by H in Fig. l, and this swinging motion ofthe said carrier N and slab downwardly and also the return movement are secured through the thrust-rod o, which has a suitable engagement with the cam 70 on the rotary shaft I.
