To a/ZZ whom t 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. Y

This invention relates to improvements in machines for making and imprinting envelopes, the object of the invention being to improve the construction of envelope-machines, whereby they are rendered of unusal practicability to the end of certain and rapid operation. Y

e As a preliminary to the detailed description to be hereinafter given, the nature of the invention may be more easily and clearly understood by briefiy setting forth the successive operation of the parts upon a blank to form the same into an envelope. The blanks are supplied, as usual, by a novel arrangement of pneumatic sucker or picker fingers. The blank is then conveyed rearwardly a suitable distance and is momentarily held stationary, the printing devices then acting to print the blank upon the underside thereof. The blank is then conveyed rearwardly still farther a suitable distance, and again held stationary foran instant, it then being subjected at the flaps thereof to the gumming action of the gummers, and the blank is-then further conveyed to the suitable position over the creasing-plunger, which also carries it downward onto the folding-bed. Theblank being then folded by the folding-wings is discharged into the drying-chain and inally disposed of in any usual or approved manner, and under the construction and arrangement of parts embodied in this machine at one and the same time different blanks are being printed, gum med, and folded; and, therefore, to the end of effecting the said operations in an advantageous manner, the invention consists in the constructions and combinations of instrumentalities and parts, all substantially as will hereinafter more fully appear and be particularly set forth in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification,

in which similar characters of reference indicate corresponding parts in all the views.

1n the drawings, Figure l is av sectional elevation as seen on a plane taken centrally from front to rear of the machine, and indieating, as far as it is possible so to do in a view of this scale, the positions of all the working parts constituting this invention, as well as other parts not particularly novel.

Fig. 2 is a plan view of the forward portion 6o of the machine, and Fig. 3 is a front elevation of the upper portion of the machine. These two figures are especially in illustraltion of the devices for picking up the blanks from the blank-supporting table and of the arrangement relatively thereto of the printing mechanism and ink-supplying devices therefor. 4 is a plan view of the portion ofthe maehineat the rear of that seen in Eig. 2 and under the creasing-frame,partieu- 7o lax-ly showing the folding mechanism. Fig. 5 is a vertical section taken on the line 5 5, Fig. 4. Fig. 6 is a vertical section of a construction and arrangement of parts taken on the line 6 6 of Figs. 4 and 5, and which will 75 be hereinafter referred to. Fig. '7 is an enlarged View of a folder-wing and a means for adjustably mounting the same, which will be hereinafter more fully described. lFig. 8 is an illustration in perspective of an appliance 8o for operating in conj unetion. with the platen, and actuated by the presence or non-presenee of a blank at the printing place in the machine for blanks. Fig. 9`is an enlarged perspective viewillustrative of a portion of and 5, which receive their prcperly-speeded rotary motions through suitable gearing.

c indicates the blank-elevating table, which is shown as supported on a yoke l0 and automatically'receives its gradual upward movement to maintain the top of the constantlyroo lowering pile d of blanks within`t-he reach of the pickers by means of mechanism which is but partially shown, and which will not be herein described, as constituting no part of the present invention. The supporting-yoke for the blank-elevating table is provided with a couple of vertical posts 12 l2, rigidly affixed thereto, which play through guidetubes 13 13, Afixed to the table A, and by this means the elevating mechanism yis steadily moved andguided. The pickers are of the suction class, and the same and the actuating mechanism therefor, together with the separating devices, are shown in Figs. l, 2, and 3 of the drawings, and will now be particularly described. Three picker-tubes 14 14 and 15 are provided, one for taking on and lifting at each end fiap of the blank and one for the rear flap. rl`he pair 14 14 for lifting the ends of the blank are carried in unison on the forward ends of radial arms 16 16 of t-he horizontal and suitably-mounted rock-shaft 17, which is rocked by means of the connectingrod 18, engaging the radial arm 19 of said rock-shaft, the lower end of said rod having an engagement with a cam 20 on shaft 5. As the shaft 5 vis geared down for a slower rotation than the -other cam-carrying shafts of the machine,the cam 2O has circumferenlially double sets of working-surfaces, whereby on one rotation of said shaft there will be two rising-and-t'alling movements imparted to the said end suction-pickers. The picker-tube 15 is independently mounted and moved, being carried on a support 22,-which is in the form of a radial arm adjustably fixed on a rod or bar 24, which is carried by a pair of arms 25, radially mounted on rocking journals 2U, that have suitable bearings in the brackets 27 27. One of said journals is provided with an arm 28, to which the connect-` ing-rod has an engagement, the other end of said rod having an engagement with acam 30 on shaft The suction is secured in said picker-tubes through vtheir connection with suitable suction-pumps by means of the liexible pipe-connections 32 had between t-he tubes and the pumps, respectively, therefor.

The two suction-pumps 33 33 for the pickers 14 14 are mounted on a frame 34, pivotally hung on one of the immovable supports of the machine and adapted to have a swinging movement under the action of the recip` rocating piston-rods 35 35 playing therein and which receive their motions from their connection with the radial arm 36 of a lever, another arm 38 of which lever is in engagement with and is moved by acam 37 on shaft 3. An easy movement of the pistons and not one liableto any crippling effect is insured by the lever 2li), intermediately pivoted on the end of the arm 36, and to the extremities of which lever the pump-piston ends are attached, each arm of said lever serving as a link between one of said arms 36 and the respective piston. The suction for the rear picker is secured therein by the connection therewith of one of the flexible conduits 32, which is alsoin communication with a pump 33a, (indicated by dotted lines in Fig. 1,) having` a piston playing therein and actuated by well-known means.

c c represent separator-plates adapted for a swinging movement in a horizont-al plane and at right angles to thethrow of the pickertnbes, and when the said tubes have drawn up the extremities of the blanks said separator-plates are adapted as toV suitable portions thereof to be swung under the said extremities and separate them from the remaining blanks of the pile. rllhe said separator-plates are carried on the upper ends of spindles 40 40, which have bearings vertically in tubular posts 42, affixed on the table A, the plane of movement of said plates being just above the proper level for the top of the blank pile. One of the spindles 40 has an arm 43 on its lower end, to which motion is imparted through the connecting-rod 44, the two-armed rock-shaft 45, thrust-rod 46, and cam or eccentric 47 on shaft 4. The swinging motion having` been imparted to one of the spindles, as described, the other is caused to swing in unison therewith through the medium of a connecting-rod 48, which is attached to an arm 49 at one side of one of the spindles and to an arm 50, which is projected from the opposite side of the other of the spindles. By this form of connection the separator-plates are caused to simultaneously move toward and away from each other in the same plane.

5,2 52 represent spring clips or fingers which bear on the edge portions of the blanks, as common in en velope-machin es. The end pickers are timed to operate in unison to raise the end portions of the blank before the rear flap-picker operates to raise that portion of the blank. There is but slight probability that either of the end pickers will raise portions of two blanks at once; but there is practically no possibility of both pickers raising the opposite end portions of two blanks atonce. Therefore, assuming that one end picker lifts the ends of two blanks, while the other end picker lifts the ends of one blank, one separator-plate is swung under the end liaps of two blanks, while the opposite plate is under the end flap of but a single blank. (See Fig. 3.) The rear Hap-suction picker then operating will only raise the rear portion of the one blank, for the right-hand separator,.lying over the second blank, holds such blank from being lifted by the rear picker, and the draft by the latter being centrally related as to both end flaps will only raise the rear half or other desired proportion-of the uppermost blank. The fact that while two or more blanks may at one end of the pile lie above the separatorplate thereat the uppermost blank by its other end is separated from the remainder of the pile, overcomes any suction which may exist between the top blank and the one next below, and therefore any liability of the rear roo IIO

Vard 53 and by the dotted lines z in Fig. 2.

The blank-carriage f has its reciprocating movements through a course from front to rear of the machine about equal in length to the distance between the middle of the pile CZ of blanks to the middle of the type-bed h. The blank having been brought to its position for printing is supported and confined on the forwardly-extended part of a suitable horizontal supporting part-such, for instance, as the creasing-frame 54, which constitutes the support and slideway for said blank-carriage f. In the printingoperation the type-bed moves upwardly and the platen g moves downwardly to meet same. The upward throw of the type-bed h is imparted throughthe working of cam and toggle mechanism, as common in printing-machines, and the movements of the platen are insured through the operation of mechanism which it is believed embodies some features of novelty to be now set forth.

55 represents a rock-shaft ranging across the machine and along under the arch-standard 53 and provided with a radial arm 56, to the extremity of which the thrust-rod 57, actuated by cam 5S on shaft 3, has a pin-andslot engagement, the spring 59 serving to usually maintain a pin 6i of the radial arm 56 at or near the bottom of the slot 60, which is in the upper end of the said thrust-rod 57, and except at such times as unusual resistance is present against the downward projection of the platen.

62 represents one lnemberof the platen-operating toggle and is rigidly affixed to the shaft 55, and 63 is the other toggle member, pivotally 'connected to an upper portion ofthe platen. The platen is constrained to its proper vertical movement by means of t-he Z-shaped link-arms 65, which are by their forward ends pivotally connected to the said platen in axial coincidence with the pivoting thereto of the toggle member 63, the rear extremities of said arms 65 being pivotally hung, as at 66, to a suitable fixed part of the machine. The downward thrust of the rod 57 causes the straightening of the toggle and the downward projection of the platen, the arms 65 at that time having a down wardly-swinging movement, and the spring 59 at such time serving to constitute, in substance, a medium for fixed relations between the thrust-rod 57, which has a positive movement, and the rocker-shaft arm 56. At the time the platen has been brought to impact against the blank and the type-bed thereunder further straightening of the toggle of course ceases, and whatever throw the thrust-rod 57 must have under the forcing action of its cam is provided for Without further forcing action on the platen'by the then yielding of the spring, the slotted portion of the thrust-rod moving downwardly over the pin on the arm 56.

. A device is provided to act on the rear of the blank when it is brought, to its position for being printed, and consists of a finger 70, formed on the rocking rod 72, which receives its rocking motion through the connection with the arm 7 3 thereof of the thrust-rod 74, which is given its reciprocatory motion by a cam not shown, but which is provided on shaft 4:, and acts in the same manner as does the cam 58 upon the rod 57 and as other of the cams shown act upon other of the thrust-rods. Immediately the blank is brought forward to its printing position the said last-described mechanism operates to press the linger upon the middle edge portion of the rear flap thereof, holding it' upon the frame-extension 5,4, said holdethereof continuing until after the printing-bed has separated from the platen.

Novel mechanism is provided for inking .the type on the-type-bed at the time the latter is in its lowerinost position, which I will now proceed to describe. The same may be briefly stated to consist of an ink fountain or supply, as at t', a roller j, for carrying ink from said supply to and upon the border portion of the disk 7c., means for rotating said disk, whereby said inked border portion may be carried into proximity to the border of another rotatable disk Z in the same horizontal plane, a roller m, for distributing the ink which is on the approached border of the disk Zr; and spreading it upon the border portion of the disk Z, and also effecting, after the disk Zhas been turned, the spreading of the ink from said border throughout the entire surface of said disk and also for conveying the ink onto a distributing-roll o, which is provided at the rear of the type-bed, and there is another IOC IIO

roller 71.mounted for a forwardly and rearwardly reciprocating movement and for taking ink from the said distributing-roll o and inking the type, and for also having acontact with still another distributing-roll p, whichis forward of the type-bed. The plane of the top surface of the disks'f; and Z and of the distributingrolls 0 and p is coincident with the top of the type-bed when thesaine is in its lowered position.

The individual instrumentali l ies comprised in the linking mechanism just outlined will be nowr described more in detail.

The ink-supply i consists of an ink-well 162, which is supported in a position somewhat above the top of the table A, and, in fact, above the top of the disks la and Z, and said ink-receptacle has a roller 163 therein, the lower peripheral portion of which extends through an aperture in the bottom of said receptacle, and with the borders of which apy ink-supply devices. The ink-carrying roller j is mounted on asuitable arbor, the extremi- -ties 64 of which slide on horizontal guidetion with the radial arms 67 67 of the rockshaft 68, there being on said rock-shaft a radial arm 69, to which one end of a connecting-rod 8O is attached, the other end thereof being connected to an intermediately-pivoted lever 82, which lever receives its reciprocatory movement by a cam 83 on one of the cam-carrying shafts.

The disks 7c and Z have toothed borders, as clearly shown in the drawings, which mesh as gear-wheels, the one 7c being positively driven by the pallet 84, which is carried on an arm 85, hung for its center of swinging movement upon the axial post 86 of disk 7c, and receives its swinging motion by means of the link 87, connected to said rod and to one of said radial arms 67, the other disk Z receiving its slow rotary motion from its mesh with the adjacent disk Zr.

The' roller m, which is mounted to travel at right angles to the roll j, is supported on a rod 88, the ends of which are movable along and guided by iixed horizontal rods 89, and the roll 'n is also mounted on an arbor-rod 90 therefor, the ends of which are also movable on and guided by the said rods 89 89. The arbor- rods 88 and 90 are tied together or form, in substance, one frame-like structure, whereby both of said rolls are moved in unison, and the reciprocatory motion thereof is imparted by means of the link 92, which is connected to the arbor-rod 90 by its one end and by its other to the end of the curved arm 94E, affixed to the rock-shaft 95, and which shaft receives its rocking motion from the connection with its arm 96 of the thrust-rod 97, the other end of which being in engagement with the cam 98 on shaft 5.

The roller m is adapted to run over the intermeshing portions of the disks 7c and Z, having an extent of traverse from a position upon the teeth at the rear of the disk Z and slightly back of the position shown in Fig. 2 therefor to and'upon the distributing-roller 0, and therefore ink which is upon the approached border of the disk Zt will, as the roller fm, runs over such border, distribute it upon the upper surface of the intermeshing teeth of the disk Z, and then as said toothed portion of disk Z, which has received the ink in that way, has been brought toward and into the central longitudinal line of the machine coincident with the middle of the blanks and printing-bed the said reciprocating roller will distribute the ink generally over the surface of the disk Z, besides conveying same to the distributing-roll o. The said distributingroller 0 and the one p are rotated continuously by means of the pulleys 99 and 100 on their arbors and suitably-driven belts. As the roller 'm runs forward, effecting a distribution of ink on the disk Z, and also conveying ink to the distributing-roll 0the rollfnl moves forwardly to ink the type and also to convey ink to said distributingroll o. The latter roll is not absolutely necessary in the inksupplying devices; but its use is preferred, as an improved inking effect is assured.

T he blank-carriage f, moving forward un- 'der the operation of a well-known form of carriage-operating mechanism, not necessary to be described, after the printing has been effected to take the next blank, and then on its return movement to convey same to the said position for printing, due to the peculiar construction and arrangement of hook-abutments thereof at the time of making its rearward traverse, serves to convey the first blank which has been printed another step rearwardly into a position whereby it may be gu mmedbythe picker B, and also dueto the peculiar arrangement of other abutment-hooks on said blank-carriage. The blank which has been previously gummed is then caused to be moved another step rearwardly to its proper position over the creasing-frame to be creased by the plunger C-that is, the carriage has on the parallel strip-like members ff thereof,which play in suitable ways in the said frame 54, as usual in envelope-machines, three sets of hooks fr, r2, and r3, which are arranged at intervals of separation correspondsv` ing to the distance between the middle of the blank pile and the middle of the printin g-bed, or between the middle of the latter and the line of the gummer-carrying rod q, or between said line and the center of the aperture 102 in the creasing-frame, and all of which mentioned distances are substantially the same, and the extent of movement of said carriage is substantially equal to any one of said distances. rlhe operation of the said blank-carrier lnay be perhaps as well understood if it is assumed that the machine is just being started up with the said carriage in its rearmost position ready to be projected forward, and so as said carriage is moved forwardly to its limit the forward hooks r thereof are carried just in advance of the forward edge of the separated orpartially separated blank, and then on the return of the carriage t0 its real-most limit the blank is carried to said position for receiving the imprint. On the next forward movement of the carriage the second set of abutment-hooks r2 thereof at the time the forward set fr is engaging another blank at the pile, is projected just in advance of said first and then printed blank, and then as the carriage moves rearwardly to bring the second blank to position for its imprint the first- IOO ITO

named blankfis conveyed to the position for its being gummed, and again as the carriage for the third time moves forward to engage a third blank at the pile the rear set of abutment-hooks r3 engage the said first-named and then gummed blank and convey the same to its proper position over the creasing-frame while the second blank is being brought to its position to be gummed, the third blank then coming to the position to be printed, and so it will be seen that during the regular running of the machine there will be three blanks on the carriage to be moved step by step between the successive operations respectively had thereon.

I have devised as a part of the present invention improved devices for preventing the impact between the platen and the type-bed on the failure from any cause of an envelopeblank to be brought to the printing position, and said device embodies electrical appliances which are controlled by the presence or non-presence of a blank at the printing position, and which electrical appliances 'in turn` control the extent of rock of the said rock-shaft 55. Upon said rock-shaft I affix a radial arm 110, which under normal conditions has a swinging motion adjacent to but not to be intercepted, by a hooked extremity of a lever intermediately pivoted, as at 113, in suitable bearings on the table A, the lower arm 111 of said lever carrying or of itself constituting the armature 115 for an electro-magnet s. I also provide on said rock-shaft 55 another radial arm 116, preferably of wood or other material, to constitute an insulator, and upon the extremity of said arm 116 is supported a feeler-tinger or rod 118. As said shaft 55 is rocked to downwardly project the platen the said feeler 11S is also downwardly carried, so that it will bear upon the blank over the carriage and said support 54, if the blank is present thereon, and over the printing-bed, or, if absent therefrom, the end of said feeler will bear upon the said carriage or on the said support 54C of the gum-box frame. From the said carriage f or part 54, whichever is to constitute the contact-piece, an electric conductor 120 runs to the said electro-magnet, and from the latter another electric conductor runs to a connection with the said feeler, and there is comprised in one of said electric conductors, as usual for electric circuits, afbattery or other form of generator 123. The said feeler 118, instead of being a sprin g-fiu ger, as it might be, is springsupported with relation to said insulated arm 116, so as to have a yielding upward movement with relation to its carrying-arm. Soit will be seen that each time the shaft 55 rocks and the feeler 118 is downwardly moved upon the blank, then properly thereunder, due to the said blank acting as an insulation between the feeler 11S, to which wire 122 is connected, and the contact part thereunder, to which wire 120 is connected, therewill be no actuation of the electrical devices; but on the failure of a blank to properly come under the platen, the said feeler moving down in advance of the platen on making a contact establishes a circuit, and the attraction by the electro-magnet of the armature swings the hooked extension thereof to intercept the radial arm 110 in its swing and prevents the platen from being carried to an impact with the type, and at this time the thrust-rod in making its complete downward stroke runs by its slotted portion over the pin of arm 56, the spring 59 at such time being elongated, as is plain.

In this machine I employ a bottom for the folding devices, which consists of a series of metallic sections t, hinged to eachother to form an endless band, and supporting-blocks u u', upon which said sectionformed band is mounted, said blocks being supported on shafts o and o. The shaft o is mounted in fixed bearings, while the shafto has bearings in a horizontal yoke-bar 125, (which for lpurposes of rigidity and even carrying of the mechanism may be duplicated,) and the said yoke-bar by its one end is pivotally mounted on or axially coincident with the shaft o and is given an intermittent swinging motion in a vertical plane through means of the cam 126 on shaft 3 and the rod 127. This endless band is disposed within an aperture of the table and has a step-by-step movement at the time the yoke-bar 125 and the forward supporting-block u are lowered, so that after each envelope-blank has been folded and discharged `and before a new blank is brought to the action of the folder another section t will be brought upon the upper side of the forward block u/ to form the fresh folding bottom. When the yoke-bar 125 is downwardly swung, the forward movement of the sectionformed band is given by the rotation of the carrying-blocks u u by means of the palletand-ratchet device shown on the shaft of said block u at the right hand of Fig. 1 and actuated from the cam 13() and the connections 131 between same and the said pallet, the rotation of the other block beingA consequent upon the movement of the sections so secured.

The mechanism constituting the folding bed just above mentioned is more fully and particularly set forth in my application for Letters Patent for improvements in envelope-machines, filed January 2l, 1890, Serial No. 337,570; but I have combined therewith and as a part thereof certain details of construction which are of much practical advantage, being especially to the end of insuring, after the forward carrying-support u has been turned and as it is raised to its position for properly presenting the top surface of the section t thereon as and 'for the folding bottom, the rigid and immovable maintenance of the said block and section thereon in such bed-forming position. The carrying-shaft o TOO IIO

MIO

is therefore extended laterally of the machine under the table A and provided with a block w thereon, which is of greater outward extent than and corresponds externally to the block u; but said block w has its corner portions abated and forms in the present instance an octagon. The said block w is disposed as to its upper portion in a slot 132, which is formed through the table, there being a ledge 133 overhanging said slot. As the shaft fu', with the block u thereon, is lowered with the endless band and is turned, the block w of course islowered and turned, and then as the said parts are upwardly moved one of the faces of the said block fw is carried hard against the said overhanging ledge 123, maintaining the shaft and the block u as a part thereof rigid and true.

It will be noticed that the plane at which the blank is folded is a little above the top of the table A, as indicated by the line 135 in Fig. 5, and into which plane the top surface of the endless band is proj ectedwhen moved to constitute the folding bottom, and it will be noticed that the front and rear Hap-folders E and F are hinged to base-pieces 136 136, which at their under sides are cut out, as shown at 137 in Figs. 5 and 6, so as to permit the rising and falling -motion of the endless band. Each section of the folding bed has a solid portion under the opening in the creasing-frame, the superficial area thereof being greater than that of the said opening, so that invariably there will be a flat base under every fold of the envelope.

Beneath the endless band a cleansing-roller Gr is mounted upon the yoke-bars 125 and adapted to bear upon the outer and under surface of whichever band-section t is next thereabove. This roll is mounted on an arbor or has gudgeons 140, which are springsupported on the said yoke bars 125 and capable of a yielding pressure downwardly under any inequality of the surface of the said band. Beneath the said roller G is a receptacle H for a cleansing liquid or solution, having an open top, and into which liquid the said roll will, by its lower peripheral portion, be entered at each depression of the endlessband mechanism. Said cleansing-roll is rotated for its wiping action upon the sections t, due to the frietional contact with and the traveling movement of the latter. The end flap-folders J (but one of which is positively shown in Fig. 4) are hinged to base-pieces 141, which are carried on the extremities of springarms 142, which arms by their-other extremities are bolted to the table. One or more screw-studs 145 are passed with a screw engagement vertically through each base-piece 141 and by their lower ends bear upon the table, and by properly turning said screwstuds the said base-pieces may be vertically adj Listed with the utmost nicety, whereby the end-llap-folding wings may most advantageously be operated in conjunction with the bottom formed by one of the sections of the said endless band.
