CPIARLES A. TEAL, OE HOLYOKE, MASSACHUSETTS, ASSIGNOR THE I-IOLYOKE ENVELOPE COMPANY, OF SAME PLACE.
MACHINE FOR MAKING AND PRINTING ENVELOPES.
SPECIFICATION forming part of Letters Patent No. 524,288, dated August 7,1894.
Application filed July 13, 1893. Serial No. 480,357. (No model.) i
To all whom it may concern:
Be it known that I, CHARLES A. TEAL, a citizen of the United States, residing at Holyoke, in the'county of I-Iampden and State of Massachusetts, have invented new and useful Im provements in Machines for Making and Printing Envelopes, of which the following is a specification.
This invention relates to improvements in machines for making envelopes, the seams of which are at theside edges and which can be made from a continuous roll or web.
The machine which embodies the present improvements, in its operation feeds forward the paper to the action of a rotary printing mechanism, thence to rotary cutting rolls which cut out the properly shaped blank, and from which rolls the waste paper cuttings are discharged,thence to two sets of folding mechanism, the pasting or gumming devices being arranged in conjunction therewith; the printed, pasted, and folded envelopes are then carried into the drier apparatus and set off in bunches of twenty-five, or other suitable number.
The blank, from which the envelopes are formed, is cut in at one end and has the tongue or folding flap at its other, and the body of the blank has for half of its considerable length, which is twice that of the completed envelope, narrow sidewise extensions or wings which are at the opposite sides ofthe blank, extending half of the length thereof, and all as will be seen in Figures 27 and 33 to 36 of the drawings. The said side extensions are turned inwardly on the body of the gummed, aswell, preferably, as also the longitudinal marginal portions of the half of the blank farthest from the flap, the said latter half of the gummed blank-is folded over and pressed onto the half having said inturnd' and gummed wings, the tongue or seal flap being usually also gummed, but is, however, left unfolded.
An envelope, formed bya blank, folded and stuck as described, is furthermore advantageous for business correspondence, as better adapted to be typewritten upon than envelopes formed from the diamond shaped blanks.
Having given an indication of the kind of envelopes produced, it will be stated that the invention relates to improvements in the blank cutting rolls whereby it is assured that they will cut outtheblanks from the running .strip of the paper with great certainty, and
also crease or score the blanks on their proper folding lines, and all without liability of such rolls becoming smeared with ink from the already printed paper,and also to coacting devices by means of which the waste or cuttings are efficiently discharged from the machine.-
The invention further relates to the construction of the driving gears for the cutting.
rolls whereby they run'absolutely in unison there being no lost motion as the speed of the one is related to that of the other.
- The invention further relates to theconvey ers for carrying the cut-out blanks to the action of the devices which overturn the side extensions, and thence to the action of the gumming and folding devices; as well as to said overturning devices and to said gumming and folding devices coacting with which latter are means for the discharge and guidance of the envelopes into the drier chain.
The invention also relates to the arrange ment of the drier chain devices and in the.
form or construction of certain of the articulated members thereof whereby the gummed flaps of the envelopes may not be permitted to bend to contact one with the next.
The invention also relates toimprovements in the counting or bunching mechanism; and also to various minor features of improvement in different parts of the machine which experience has shown to be important and all as will be rendered apparent hereinafter. And'to these ends the invention consists in the various combinations of parts or devices,
and the construction or formation of certain of the parts all substantially as will hereinafter be fully described and set forth in Lh claims.

swinging from the point 59, at one side of the machine, so that they may, at pleasure, be bodily carried away from the printing cylinder; all of said distributing rolls, and the transmitting segment, 51, have intermeshing gears, receiving their motion by their mesh with the gear, 60, on the printing cylinder.
Thesupply roll in the ink fount moves only as the transmitting segment passes it, its motion being imparted by the connecting-rod,

supported on the bar, a, while the ink fount' is adj ustably mounted on the said support, I). All of these said inking devices are mounted to swing as aforementioned, on the vertical axis, as seen at 59, by being'supported at one side upon the arm, 70, which has the depend ing stud at its lower end which sets into the This block is adapted to slide for adjustment horizontally in the direction of the length of the machine in ways" therefor in another block, 74, .which is vertically movable on the framing of the machine. The adjusting screw, 7 5, ef-
- fects the vertical adjustment of the block, 74, ?5
relative to the frame, while the screw, 7 6, engaged with the block, 73, having the screw engagement with the block, 74, insures the horizontal adjustment, all whereby theinking rolls and auxiliary parts may be given their proper co-operative relations to the printing cylinder, whether larger or smaller,
as variously employed. When the support for the inking devices is so swung as to bring the rolls, 57, 57, to contact with the printing cylinder, B, said support is immovably held by the dog or latch, 77, which is pivoted on a supporting arm of the frame and adapted to be swung to endwise contact with a part of the'ink roll support, a. The equipment of the frame, I), which carries the segmental ink transmitter for its adjustment by a swing movement whereby the i proper contact between the inking face of the segment and the face of distributing roll, 53,
may be insured, is by means of passing the shank" of the headed screw, 78, loosely and vertically upwardly through the forward extension of the frame, 1), with a screw engagew ment up into the cross -bar, a the adjust- 5 ment insured by turning the screw 78 is held by turning the screw, 79, (which passes with a screw engagement through the said frame extension,) to firm endwise bearing against the under side of said bar, a

The printing cylinder is illustrated in sec- 7-c tion in Fig. 10 and in partial cross section in Fig. 9, and is formed with the annular depression, 86, with the undercut sides for the reception of the segmental type sections, 87. For the insertion of these type sections the printing cylinder has, at one end, the removable head, 88. It will be now manifest that by releasing the dog, 77, all of the above described inking devices may be bodily swung a quarter way round, more or less, and entirely free from the printing cylinder,the
gearing for these rolls being thrown out of mesh with the gear 60 of the printing cylinder.
I The printing devices just hereinbefore described constitute the subject matter of a separate application forpatent filed by me January 11, 1894, under Serial No. 496,460.
The blank cutting rolls, D and F, are journaled to run in peripheral contact the one with the other, and at exactly the same speed lines, shown in said Fig. 27, upon which the.
blank is folded in the making of the envelope, and to the end of assisting in'the discharge of the waste cuttings free from the rolls and out of the machine and also insuring the freeing of the cut blank from peripheral contact with the one or the other of the rolls whereby the blank may with cer-, tainty be carried straight forward to the folding devices for. the side extensions, m The development of the peripheral surface of the lower roll, F, is the same'as the form of the said illustrated blank, the curved depression, 90, across the face of this roll cor.- responding to the transverse part of the Waste paper, which divides one blank endwise from ICC IIO
its
the next, and d, 01, represent the cutting edges of the r0ll,F, while,f,f, represent the cutting edges of the upper roll, D, which are formed by the boundaries of the depressed portions of said roll; the cutting edges of the one roll match as the rolls rotate in unison, for shear actions,
as common in rotary rolls for cutting paper and other thin material. In practice the upper roll,
and a semi-cylindrical portion of the lower roll are equal to the width of the paper fed through the machine, and which is the same as the transverse dimension of the blank between the outer edges of the side extensions, 00 00 thereof; and, therefore, as plain, it does not become necessary to cut away the side portions from. the supply paper for half of the length of each blank. The rolls are also provided with the longitudinal and transverse,
4. szaes matching, narrow, scoring ribs and depressions, 92 and 93, so that as the blank is cut out it is also scored on the proper folding lines. The middle portions of one or both of the rolls are reduced or depressed, as at 94, Fig. 15*, so that the freshly printed paper from which the blank is being cut may not smear the roll over which it passes with ink, by reason of its having no pressure contact therewith. The prominent portions, 91, 91, of the upper roll correspond in form to the waste stock, the curved transverse part, 91, matching into the said crosswise depression 90, of the lower roll, while the prominent side parts, 91, 91, of the'upper roll fit down for the shearing action by matching surfaces of the cut away or shortened part of the lower roll. One of the rolls,-as shown, the upper,-has the rubber treads, 95, constituted by the rubber bands set into circular depressions therefor whereby an efficient frictional contact for the forward feed of the paper is insured. The said prominentparts, 91, 91, of the upper roll have at their forward extremities the short radial studs, 96, 96, which bear to impart a stretchingtension on the paper as the forward transverse shear cutting thereof is to take place,whereby such cutting action may be rendered positive and complete. The bearing ends of the said studs, being farther from the axis of the roll than-the normal plane of the forwardly traveling paper, bend the paper slightly, as indicated in Fig. 14, for the stated purpose. Furthermore, each of the prominent parallel portions, 91, 91, of the upper roll have at their rearward extremities the studs, 97, 97, the ends of which are serrated. As the two rolls rotate, the ends of the studs, 97, and the plate spring, 98, supported Within the cut away ends of the lower roll, come together, and the ends of the said studs being farther from the axis of the upper roll than the normal plane of the traveling paper have accelerated movements relative to the blank proper which is being cut out, so that the rear extremities of the side sections of the waste are drawn forwardly with a slightly accelerated movement away from the forwardend of the side extensions, :0 m insuring a more efficient and complete cutting and a better clearance of the waste.
The spring, 98, affords a yielding bearing for the underside of the paper, the studs having a slight slipping or wiping movement relative thereto, and the co-operative relations of these parts are indicated in Fig. 13.
The tendency of the cut out blank is to lie within the depression of the upper roll which is bounded by the shear cutting edges, f,f, while the cross part of the waste lies within the said depression, 90, under which is the follower or clearer, g, and thus as the rolls rotate the blank will move over the horizontal plate, 99, the rear edge of which is very near to the surfaces of the rolls at their throat. The upper roll, next to the cross protuberance, 91, has the rubber springs 41 set into depressions thereof, these'serving to clear the 7 radially projecting studs, 102, which revolve in unison with the rolls and on which are fitted for revolution, and also slight radial sliding movements, the blocks, 103, 103, in which the ends of the clearer are secured. Each of the blocks has the projection, 104, which in its movement past and in contact with the stationary cam, 105, forces the blocks and the clearer outward, so as to expel the cross portion of the waste from the depression, 90, just after such has been severed from the blank. The springs, 106, secured on the ends of the roll and bearing on the blocks, normally maintain them inwardly and the clearer in the base of the said depression, 90. vIt will be perceived that there is, close to the throat of the lower cutting roll, under the aforesaid plate, 99, an idler roll, 100. As the waste cuttings are downwardly directed, moving with the lower roll, the plate springs, 98, 98, which are on and at the ends of the said lower roll, moving in contact with the said idler cause the rotation thereof for hastening and rendering more positive the discharge of the wastestock down wardlyaway from the throat of the rolls.
The conveyers for carrying the cut out blank from the rolls through or'between and subject to the action of the stationary folders for the side extensions, consist of the two upper and lower pairs of longitudinally running endless bands, 110, 112, preferably of rubber, mounted on the wheels or pulleys, 113, 113, and 114:, 114, therefor, which have movements at their peripheries at the same rate of speed as the feed of the paper through the printing and cutting rolls as well also as afterward through pasting and folding rolls, H, J, K. The upper bands have between the upper and lower courses thereof the idler' rolls,11l, of increased diameter, by means of which they are borne upon for insuring the proper frictional contact. On the shaft carrying the rear upper wheels, 113, for the conveyer bands, are the winged wheels, '115 the wings or arms thereof having a greater radial extent than the rims of the said wheels,
113, and, therefore, the said arms have movements considerably faster than the travel of the blank, and serve to strike against and downwardly throw the forward end of the blank should it, perehance,-as sometimes occurs,-move upwardly around hugging the periphery of the upper roll. This provision has been found important and very useful to insure thecontinuous running of the ma chine properly and without clogging.
.Thestationary folders, h, h, f! the side extensions, 00 of the blank, are especially illustrated in Figs. and 21, and 27 to 30,
' inclusive, and are formed by opposite separated parallel and longitudinally ranging metallic castings or parts suitably horizontally supported; and the inner working surfaces of these folders merge from horizontal planes at the rear, as seen at 116, to downward and inward inclines, as seen at line 2929,-and the section thereof Fig. 29,further merging into vertical sides,see line 3030 and Fig. 30,and then to surfaces constituted by the inner faces of overhanging ledges,-see lines 3131, and 32-32, Fig. 28, and Figs. 31 and '32, and in connection with these various cross sectional views observe the indications of the positions of the side extensions which are being overturned. The blank, after passing through the folders, h, h, for overturning the side extensions, next passes through the rolls, H and J, receiving the paste on its upper side in longitudinal lines as indicated at 00 in Fig.
The upper roll has at its peripheral portions, near its ends, the raised gumming surfaces, 118, 118, with the reduced or recessed portions, 119, so that the lower roll may not receive any of the gum atj the places thereon which are left uncovered by the space between one blank and the next following;
The gum is contained in the gum-box, 't', which is shown above the folders, h, h, and to the rear of the roll, [-1, the gum supply wheels, 120, 120, running in the box while the gum transmitting disks, 122, 122, are mounted between and ,in peripheral contact with said rolls, 120 and H. The forward end of the blank runs forwardly over the horizontal plate, is, its extremity overlying the roll, K,
as indicated in dotted lines at as, when the grippers, 9, at each end of the roll, J, press upon the overturned gumined extensions, 00 of the blank atits opposite edges next behind the cross folding line, :10, so that the blank, instead of passing horizontally farther forward over the roll, K, is carried downwardly upon and with the forward face of the roll,J,th'e
gummed forward half which had been moved forwardly over roll, K, being new rearwardly withdrawn and pressed. upon the rear half of the blank, this operation being in a manner indicated in Fig. 22, as also in Fig. 34,-the
.fold of the envelope, that is at the middle transverse line of the blank. The roller, 150, is journaled on the arms, 150, of thebrackets which have pivotal supports and to which are applied the springs, 150, for causing the roll to have its yielding pressure against the periphery of the said rolls, J. It will be here observed that the grippers bear upon the marginal portions of the blank only a short distance across the gummed strip, 00 as indicated in Figs. 25 and 26; the grippers are operated so as to seize the blanks as they come up to the top of the roll, and the operation thereof and of their actuating means will be now described.
The roll, J, has ear-lugs, 125, at its ends with the longitudinal slots, 126, while each gripper consists of a block orbody,127, to lie across the peripheral surface of the roll, J, at its end, with the angularly extended ear-lugs, 128, 128, to project at each side of the lug,
125, the pin, 129, passing through the said ears and said slotted lug. The spring, 130, mounted on the end of the roll and bearing against the outer end of the gripper exerts the stress to maintain. the gripper in its inner disposition, the innerendof the slot, 126, then being next to the pin. Each gripper therefore, is adapted to havetwo movements,
a bodily sliding movement parallelwith the axis of the roll, and a swinging n1ovement against and away from the peripheral face of the roll. Each gripper is also provided with the outwardly extended lug, 132,encroaching over the path of which is the under cam surface, 133, of a stationary fixture, 134, see Figs.
20, 22, and 26. As the roll, J, assumes the position where the grippersiu their revolution apchain by the cam surfaces, K Fig. 2.3, on the ends of the adjacent roll, K,see Fig. 23,'
which, at the proper time contact with the portions of the grippers to force them outwardly.
It will be perceived, on reference to Fig. 26, that the body of the gripper is provided at its top with a projection, or shoulder, 7' somewhat outside of the lip, or part, 3' of the gripper which directly presses upon the envelope between the two thicknesses thereof, and it is too against this portion of the gripper that the v cam, K of the roll, K, seasonably impinges. In order that the forward end of the blank, on emerging from between the rolls, H and J, may be held from sagging down, and so that it may be directed over the horizontal plate, 141, (the rear edge of which, however, is downwardly inclined,) the roll, J, carries at its ends, within suitable recesses therein which open to the periphery, fingers, 140, which are pivotally mounted and substantially cam operated all so that at-the proper time the fingers are swung outwardly beyond the periphery of the roll holding the paper up until'it has run onto the said horizontal plate, and all as indicated in Fig. 20. The said fingers, 140, are carried on, and as parts of the studs or short shafts, 142-, set in the sockets therefor in the roll, each of said studs having the inwardly directed arm, 113, with the spring, 14st, secured thereto and to the roll. Upon the aforementioned fixtures, near the ends of the roll, are the cam or wiper projections, 145, to be so impinged upon by said arms, 143, as they revolve, as to swing the device for the action explained. Adjacent theforward lower portion of the roll, J, and under the pressure roll 150 are the vertical guides, 152, 153, for the envelopes, while below them are the prop erly driven rollers or feed wheels, 154, which positively run the envelopes down into the chain,-L, therebelow. The roll, K, just in advance of the folding roll, J, has thereon the gumming segment, 155, which receives gum from the roll, 156, running in the gum-box, 157, and-the relation and rotation of this roll to the feed of the folded envelope are such that just as the rear flap is about to pass down between the guides, 152, 153, the said segment comes to the contact therewith to gum it, the forward face of the .roll, J, serving as the support for holding the blank firmly to the gumming impact.
All of the several and various rolls described are run at corresponding rates of speed by suitable trains of gearing which are indicated in the drawings, but which will require no description, as embodying no novelty, except in so far as will be hereinafter particularly described, with respect to cer-. The power is trans-. mitted to the gearing through the main shaft, M, and the chain, L, is driven by the shaft, 178, through the gearing to shaft, 167, which carries the upper end of said chain, L. The envelopes, being carried upwardly and for-l wardly by the chain, are, as the chain breaks over the sprocket gear therefor on the shaft, 167, engaged by the two pairs of horizontally tain portions thereof.
mounted spiral conveyers, 168, 168, and car- 'ried to the double set of chains, N N. Each one of these chains, N, consists of a series of sections, Z, and each of these sections, as seen in Fig. 40, comprises a vertical bar, Z with the fingers, Z Z extending horizontally from its top andbottom, and the said bar is provided at its upper and lower ends with the perforated 1ugs,Z 1", arranged step-like, as shown, so that the inner lugs, Z of one chain section may match into the outer lugs, Z Z of the next section to'be held by the pintle, or rod,
Z. By having the lugs, Z Z of sufficient extentof projection beyond the lines of the fingers, Z and having the perforations through which the pintles, Z, pass at the desireddistances apart, the intervals between the fingers may be such as to easily accommodate bunches of twenty-five of the envelopes between every two of such chain members. These chains are mounted on suitable, axially vertical, sprocket shafts, 169, 170, therefor, so that the fingers of the inner or approached courses of the two sets, move in opposite pairs horizontally forward,-see Fig. 39,- they having a forward step-like movement after the chain, L, has moved through the distance of twenty-five of its fingers, and serve as bunchers for the envelopes. Each of the said spiral 'conveyers is formed, or secured upon,
mit, byits gears 179 and 180, the proper rotation to shaft, 17 1, for driving the upper spiral carrying shafts.
The upper and lower spiral carrying shafts have spur gears, 182, 182, 182, 182, thereon, those on the lower being driven by those on .the upper through the intermediate spur gears, 183.
The forward sprocket shaft, 167, for the chain, L, has thereon the bevel gear, 184, meshing with which is the bevel gear, 185, on the shaft, 186, on the rear of which shaft is the spur gear, 187, the same receiving its rotation by the idler gear, 188, between it and the adjacent gear, 183.
The rear vertical sprocket shafts of both of the chains, N, N, have bevel gears, 190, 190, thereon with which mesh the bevel gears, 192, 192, on the shaft, 193. This shaft has fixed thereon, the ratchet wheel, 194, and, loose thereon, the pawl-carrier, 195, with the springpressed pawl, .196, which takes into said ratchet wheel. The pawl carrier has the crank-like arm, 197, with which is connected the rod, 198, the rear end of which is subject to the action, for its reciprocatory movement, of the snail or involutc cam, 199, which is fixed on the shaft, 166, which forms the journal support. for the rear sprocket wheel, or
sheave, for the chain, L. The spring 200, exerts the tendency to hold the rear end of the rod, 198, to the edge of said cam. As shown the rear end of the rod is pivoted to the upper end of a lever, 202, which atits lower end is pivotally supported on the floor. The said snail cam, 199, is as one with the ratchet wheel, 165, and as seen in Fig. 2 the ratchet wheel has its step-by-step movement through means of the pawl, 164., on the reciprocatory pawl-carrying lever, 163, to an arm of which lever, is secured the end of the eccentric rod, 162, the eccentric being indicated by dotted lines at 160. Inasmuch as the ratchet wheel, 165, which is rotatable independently of the movements of the chain, or its rear end supporting sprocket wheel, has twenty-five teeth,
and the cam, 199, rotates as one therewith,
the members of the chain, N, N, will be moved forward one step, after twenty-five en-
