SPECIFICATION forming pari: of Letters Patent No. 362,998, dated May 17, 1887.

Application filed February 8, 1396. Serial No. 191,158. (No model.)

To all whom it may concern.-

Be it known that I, OLIVER B. REYNOLDS, a citizen of the United States, residing at Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Duplex Oscillating Printing-Machines, of which the following is a full, clear, and exact description, refer ence being had to the accompanying drawings, forming part of this specification, in which Figure 1 represents a side elevation of a printing-press embodying my improvements, and showing portions of the inking apparatus removed from the lcftliand side of the press.

My invention relates to a duplex printingpress designed to print separate sheets or to print from a web, either one or both, as desired; and my invention consists in the devices hereinafter described and specifically claimed.

To enable others skilled in the art to which my invention appertaius, I will now describe its construction and the manner in which I have carried it out.

In the said drawings, A represents themain frame, of any suitable form and construction and designed to sustain the working portions of my machine. A transverse shaft, 2, journalcd between the sides of the main frame, carries upon one end a suitable balance-wheel and driving-pulleys (not shown) and upon its opposite end a pinion, 8, which meshes with a spurgear, mounted upon a transverse shaft, 5, which carries on its end opposite the gear 4 a face-plate, 5, as shown in dotted lines in Fig. 1.

The spur-gear 4t and the face-plate 5 are provided with crank-pins 6, to which the inner ends of suitable comiccting-links, 7, are pivotally attached, the outer ends of said links being secured to both sides ofsuitable swinging frames, B B, which carry the typebeds and inking apparatus. The construction and operation of these swinging frames and their several connections will be hereinafter minutely described, in conjunction with certain other features with which they cooperate to produce the desired result.

The main frame of the machine is provided with any suitable means for attaching and se curing two stationary platens, which are located upon two sides of said frame, and in such position that they receive the full impact of the movable or oscillating typebeds, which alternately come in contact with the platens during the movement of the spur-gear 4. and faceplate 5 and the link-connection between these two features and the oscillating frames B. This manner of attaching the frames B directly to each othcr'is of importance, as the alteriiate movements of said frames are counterbalanced, thereby increasing the capacity of the press and diminishing the noise and vibration incident to all presses when in operation.

Upon the lower portions of both sides of the frame A are seen red brackets 6, to which are pivotally secured the lower ends of verticallyarranged arms 7, the upper ends of said arms being attached to a suitable frisket-frame, O, which consists, essentially,of a transverse rod, 8, having elongated slots 9 formed therein to receive and furnish the necessary means for adjusting laterally the fingers c, which hold the sheet during the time the impression is being made. These fingers c not onlyhave a lateral adj nstment, but are slotted at l0,whcrcby said fingers are capable of vertical adjustment, this compound adjustment being necessary to enable the press to print sheets of different size, as it permits the frisket-frame to be adjusted laterally and vertically to accommodate itself to the length and breadth of sheets to be 2 ceases printed, or to regulate the fingers to the different widths of paper when printing from a web.

Suitable short arms, 12, secured to the shaft 8, have attached to them guides 13, which are affected by the movements of the paper-carrying device, and which are designed to permit the frisket to come squarely against the paper at the proper moment, or after the paper-carrying device has engaged the lower or camshaped end,14:,of the guides. It will thus be manifest that during the downward movement of the paper-carrying device, which is actuated in a manner I shall hereinafter describe,it permits the frisket-frameto be drawn against the paper by the action of the springs 15, secured to the arms 7 and frame A, respectively. As soon as the impression has been made,the return movement of the papercarrying device, by again engaging the cam-' shaped portion 14 of the guides 13, forces said guide and frisket outward, the latter thereby releasing the paper and permitting the same to be deposited upon a table, as I shall hereinafter describe. To better define this portion of my improvements I will now describe the construction and operation of the paper-carrying device, and indicate a preferred mechanism for operating said device,ivhereby during its reciprocating movement it automatically causes the frisket to engage and release the paper at stated intervals.

Within suitable journals on the main frame A is mounted a transverse shaft, 16,upon which.

levers or walking-beams 17 on both inner sides of the frame A are centrally pivoted,as shown in Fig. 1. The outer ends of these beams 17 are provided with a series of holes, 18, to any one of which are attached the lower ends of suitable yielding rods,which connect the walking-beams 17 directly with the paper-carrying device, whereby the latter is positively operated by the alternate movements of the former in a manner and for a purpose to be herein-, after described. This connection between the papercarrying device and the walking-beams is of peculiar construction, it being divided into two parts, the lower portion, 0, having a head, a, with aseries of holes formed therein, while the upper portion, b, which is attached to the paper-carrying device,is provided at its lower end with a yoke, d, as shown in Fig. 1. The lower portion, a, of this connection passes through the yoke d, and carries upon its upper end a plate, 6, which furnishes a bearing for the upper end of a spring, f,coiled around the shank of the lower portion, a, of the connection, and between the plate 0 and lower face of the yoke f, thereby forming a yielding connection, which is-necessary, as the papercarrying device will come in contact with a stop, 19, on the oscillating type-bed a short time before the walking-beams 17 have made their full downward stroke, thereby relieving the paper-carrying device of the strain that would otherwise be brought upon it, as the adjustment between the lower portion of the flexible connection and the walking-beams 17 cannot always be made with that minuteness that is desirable and necessary to the successful operation of the press.

As before stated, the upper portion-of the connection between the walking-beams and paper-carrying device is attached directly to the latter, and is positively operated by the movements of the former. Therefore, to give a steady and uniform motion to the walking beams, I introduce between them and the driving mechanism a mechanism substantially as follows: 7 7

On the crank-pin G, projecting from the spu rgear 4, I attach an arm, 20, the upper end of which is brought nearer the center of motion of said gear, thereby causing said arm toltravel in a circle much smaller than the one the crank'pin 6 itself would travel in, thereby decreasing the movement of the walkingbeams with relation to the travel of the spurgear 1' and its crank-pin. A red, D, furnishes the necessary connection between the end of the arm 20 and one of the walking-beams, and during the rotation of the spur-gear oscillates the walking-beams and causes the paper-carrying devices to travel up and down their guides-tracks D and operates the frisketframe, for the purpose previously described.

The paper-carrying device is illustrated on an enlarged scale in Figs t, 5, and 6, and comprises two end pieces, 21, which furnish the necessary bearings for the working portions of the same. Suitable anti-friction rollers, 22 and 23, are mounted between the side pieces, 21 and engage, respectively. the front and rear faces of the guide-tracks D, and permit the paper-carrying devices to have a free movement up and down, they being guided by said tracks to operate, in their ascent or descent, the frisket, as before described.

A centrally-pivoted latchingdcver, 24, is mounted upon one of the side pieces, 21, and

is provided with projecting pins, 25 and 26,

main frame of the machine, and causes said latch to yield, as shownin dotted lines, Fig. 7, to permit the said pin 25 to pass beneath it. As soon as the latter object is ac complishcd the walking-beams 17 come at rest, thereby leaving the pin 25 immediately beneath the pivoted latch 27. It is now evident, as the walking-beams 17 begin their return (upward) motion, the pin 25 comes against the lower face, 27, of the pivoted latch, which has been returned to and held in its normal position by the spring 29 and stop-pin 30, and

this time causes the lever 24: to yield suffi ciently to escape the lower face of the latch 27. It will be observed this movement of the lever 21 not only permits the paper-carrying device to make its upward movement, or to return to its normal position, but it is designed to affect the position of the nippcrs 31 and 32, the former of which is pivoted and has on its inner face a cam, 33, having a notch, 32, with which the inner end, 21, of the latch 21L is designed to come into engagement. Thus it is evident, as the lever 24 is being forced from its normal position by the action of the latch 27, the end 21 of the 1evcr24c is brought against the cam 33 and forces the nippcr 31 outward until the notch 32 is engaged by the arm 24, when it will be found the lever 24 is held in a locked position and the nippers 31 and 32 are open, in which position they remain, passing upward to receive a fresh sheet of paper, or, if the operator is printing from a web, permitting the paper to pass between the nippcrs as the paper-carrying device is moving upward. In either case the nippers remain open until the pin 26 on the lever 2t comes in contact with stops St or 35 at the upper end of frame A and near the top of the guide-tracks D, as shown in Fig. 1.

If the operator wishes to print sheets, the stop is placed in the position shownin Fig. 1, and the paper-carrying device rides upon the curved upper end of the guide-tracks D, in which position the nippcrsrcadily take the projecting edge of the sheet at the same moment the stop 35 engages the pin 26 and forces the end 2i of the lever 24: from its engagement with notch 32, and enables the nippcr 31 to close upon the nippcr 32 with sufficient friction to hold the interposed edge of the sheet in position as it is being carried downward over the face of the platen, the closing of the nippcr 31 being accomplished by a rod, 36, pivoted to said nippcr and carrying a nut, 36, the said rod passing through a lug, 37, on the side of the paper-carrying device, and a spring, 38, coiled around said rod, between the lug 37- and nut 36, whercby,when the nip per 31 is released, the spring draws the same against the nippcr 32, as shown in Fig. 5, the pivoted lever 2% being also drawn to its normal position by the act-ion of a spring,39,and'

stop 40. In addition to the rollers 22 and 23, the paper-carrying device carries upon its sides small antifriction rollers 40, which are the rollers that operate against the face of the guides 13 to affect the position of the frisket.

The nippers 31 and 32 consist, cssentially,of a curved and flat plate, respectively, and extend entirely across the platen.

Should the operator desire to print from a web, the same mechanism is employed, none of the several features being modified except the stop 31, which must then be thrown downward, as shown in Fig. l, in which position it releases the lever 21 from engagement with the nippcr 31 and permits the nippers to take a new hold on the web and carry it downward to be acted upon by the combined action of the movable type-form and stationary platen. In printing either from the web or from individual sheets it is necessary to stop the pa percarrying device just prior to the moment the typeform comes against theplatcn. Therefore, in addition to the stops 19, some means must be adopted to limit the upward-and downwardmovement of the papercarrying device when printing from a web, and when it is desired to vary the size of sheet to be printed and to limit the downward movement only when individual sheets are being printed, it being evident the said papcr-carrying device must make its full upward stroke in this instance, as the said device should practically advance high-enough upon the curved portion of the guide-tracks D to readilytake hold of the edge of the sheet. Therefore, to meet these several requirements, I form the series ofholes in the ends ofthe walking-beams l7 and flexible connection, so that by chang ing the lower end of the said connection from one point to another I increase or diminish the length of travel of said carriage. Thus, for example, if a very small sheet is required I connect the lower hole in said connection with the hole near the pivoted center of the walkingbcam. This gives a shorter downward movement, and therefore less travel to the papercarriage,and by reason of the duplex construction of the press I am at liberty to make one paper-carriage make a short movement and yet permit the opposite onc, by mak ing the connection at the extreme end of the beam 17,to make its full movement,and thereby print a much larger sheet at the same time the small sheet or web is being printed. Thusl am enabled to construct a press which is capable of printing two jobs of different sizes (and colors, ifdesired) at the same time, the movements of one portion of the machine not conflicting with the opposite movements of the opposite portion,but, instead, serving as a counter-balance for the same and producing a compact substantial double acting press designed to print from two webs at one time two sepa rate sheets at one time, or to print alternately from a web at one side and sepa ate sheets at the opposite side, the paper in either case being automatically received and released.

I will now describe the inking-rollers and the mechanism for transferring the ink from the fountain to the rollers, these several features being duplicated on opposite sides of the machine, although I have shown the inking apparatus on but one side.

The movable typebeds H H are constructed with rearward extensions 71'. Upononeof each the inkingrollers ll are designed to pass during the oscillating movement of the swinging frames B. The inking-rollers 41 are attached to a pivoted frame, 42, (see Figs. 1, 2, and 3,) and are operated by suitable eonnectingrods, L, attached to saidpivoted frames on opposite sides, the lower ends of these rods L being loosely connected to the outer ends of levers or walking-beams M, pivoted at their centers to the main frame, as shown in Fig. 1, and operated to cause the inking rollers to pass over the face of the type-form and to come at rest on a large ink-roller, to be hereinafter described.

Upon the main drive-shaft 2 is secured a pinion, l, which meshes with a gear-wheel, m, on a transverse shaft, 01-, said shaft carrying on its opposite end a pinion, 0, which meshes with and communicates its motion to a gear-wheel,p, on a transverse shaft, r. A. crank-arm, s, on the shaft 1' has attached to its outer end the upper end of aconnecting-rod, N, whoselower end is attached to the walking-beam M at a point between the outer end of said beam and its center of motion. From this construction it is clearly manifest the rotation of the driveshaft and the pinions 3 and Z alternately oscillates the swinging frames B B, which carry the 'type-forms, and also operate the inking rollers to pass over the face of the type in one direction during each of the oscillating movements of said frames.

I will now describe apreferred form of mechanism for causing the rollers which take the ink from the fountain and the inking-rollers 41 to approach each other, whereby the latter rollers receive from the former at each oscillation of the press an amount of ink sufficient to supply the type for the ensuing impression,

, the several mechanisms employed to carry out the feature being arranged to travel a distance sufficient to cause the two series of rollers to meet at a point near the outer ends of the extensions h of the type-beds. Upon shafts 43, which furnish the necessary bearings for the pivoted ink-roller frame 42, is mounted asegmental gear, 44, which is designed to engage a pinion, 45, on a shaft, 46, running parallel with the said shaft 43. On the shaft 46 are rigidly mounted arms 47 47, which project outwardly and furnish the necessary means for sustaining a large roller, 48, which is mounted to revolve 011 a shaft, 49, having on one end apinion, 50, which meshes with the teeth on alarge stationary rack, 51, mounted on a boss, 52, projecting from an extension, 53, of the swinging frames 13, as shown in Figs. 1, 2, and 3.

The inner periphery of the roller 48 is provided with oppositely-arranged ratchets 53 an i 54, and the shaft 49 is provided with a sleeve, 55, having sockets 56 and 57, (see dotted lines, Fig. 2,) in which are mounted springactuated plungers 58 and 59, which are de signed to engage the ratchets 53 and 54 to rotate the roller 48. It will now be manifest the movement of the walking-beams M operates the pivoted ink-roller frame 42, and this frame, being rigid on the shaft 43,0perates the segment 44, which in turn rotates the pinion 45. The arms 47 47 being rigid on the shaft 46, it is evident said arms must describe the are of a circle, and iu making this movement they carry with them the roller 48. While this portion of the mechanism is making its movement, the inking-rollers 41 and frame 42 are also making a similar motion, and just before the press has made its full stroke it' oscillating movements of the press, its-next position will be at a point at or near the extreme outer end of the lower extension, h, of the type bed,where it again transfers the ink to the rollers 41. By this means a systematic and even amount of ink is distributed to the rollers 41, and the impressions will therefore be of a uniform appearance.

It has been found by actual experience that after repeated usethe ink will form ridges or creases on the face of the roller48 at thepoints where the rollers 41 come against the face of said roller 48. Therefore, to obviate this difficulty, and to keep the face of the roller 48 smooth and free from ridges or other irregularities, I impart to said roller during its movement a motion transverse to its rotation. This enables the roller 48 to present all portions of its face to the action of the rollers 41, and it necessarily gives more desirable effects in the production of uniform impressions than would occur if this transverse movement was not given to said roller. To accomplish this important result I construct the roller 48 with a projecting flanged hub, 60, upon which is placed a loose collar, 61, through which pass pins 62, that have attached to their outer portions the bifurcated ends of a lever, 64, pivoted to a lug, 65, projecting from the arm 47. The opposite end of thelever 64 passes through a slot, 66, in said arm, and carries on its extreme outer end a small anti-friction roller, 67, which is designed to ride upon the in clined face-of a fixed cam, 68, on one side of the extension 53 of the frames B during the rotation of the shaft 46. Thus it will be seen as the shaft 46 rotates and carries the arms 47 and roller 48 upward, the said roller 67, acting on the cam 68, operates the lever 64 and imparts to said roller 48 a sliding movement transverse to its rotation. As the lever 64 is forced from its position laterally, I introduce between said lever and ahook, 69, on the arm 47 a spring, 70,-whieh always keeps said roller against the face of the cam,

In addition to the features enu merated above, and to bring every possible portion of the face of the roller 48 to the action of rollers 41, I employ another mechanism, which is automatic in its movement and is designed to check the rotation of said roller in one of its movements. This mechanism is as follows: An arm, 71, extends vertically above the rack 51 and carries at its top an adjustable cam,

72, and the plunger 56 has projecting from its side and through a slot in the socket a pin, 73, which comes in contact with the cam 72 and temporarily releases said plunger 56 from its engagement with its ratchet 53 and stops the rotation of the roll 48. The rotation of the shaft 19 is so timed, however, that the pin fails to engage the cam on the forward movement of the roll 48 toward therollers 41; but after the said roll has moved a short distance on its return from the rollers ll (see dotted position, Fig. 3) the pin meets the rounded face of the cam 72 and withdraws the plunger from its ratchet. The rotation of the roller 48 will now cease, as the opposite pawl or plunger, 57, simply slips by its ratchet 54. Therefore when the pin 7 3 escapes by the cam 72 the position of the roll 48 will have been changed with relation to the shaft, and when brought to the action of the roller 41 again a new portion of said roll will be presented.

Bearing with slight friction against the periphery of the roller 4.8, and in front of the same, are the small rollers 74, mounted in arms 75, pivoted on bosses 76, projecting inwardly from the arms 47, and held together by springs 77, as shown in Figs. 2 and 3, these rollers serving to distribute the ink over the face of the roller 48.

The fountain 78, from whence the roller 48 receives its ink, is of ordinary construction, except that it has a roll, 79, mounted on a shaft, 80, from whence depends a slotted arm, 81, which is attached to the slotted end of a rod, 81, projecting from the main frame A and earryi ng an adj ustablestop, 82, the purpose of which will be hereinafter fully described. A suitable bracket, P, projecting from the swinging frame B, supports the ink fountain 7S, and also furnishes a bearing for a transverse shaft, 83, on which is mounted, on each end, two upwardlyextending arms, 84 and 85, the former of which is rigid on the shaft 83, while the latter is loosely mounted thereon, the two arms being connected by springs a and the arms 84 being connected to the fountain by springs l), as shown in Figs. 12 and 13. On the shaft 83 and outside of the arms St is attached a bell-crank lever, 86, the lower arm of which carries an adjustable weight, 0', which keeps said arm against a stop, d, projecting from the shaft 83, as shown in Fig. 13.

From this description of these parts it is manifest the oscillating motions of the swing ing frame B, which carries the ink-fountain and connections, causes said devices to move forward until the upper arm, 0, of the bellcrank lever 86 comes against the adjusted stop 82 on the rod St. The forward movement of the frame B and connections will now force the lower arm of said lever from its stop d.when the spring I) will draw the rollers g 9' against the roller 79. At the same time the pin j", which connects the arm 81 with the rod 8t,will travel the length of the slot in the red, when the rod, through the agency of a suitable pawl and ratchet, h, will rotate the roller 79 and present a new surface to the action of the rolls /g. On the return movement of the frame B the stop 82 is released from its ongagement with the arm 6, and the weight 0' permits the bell-crank lever 86 and rolls 9 and g to assume the position shown in Fig. 18', while a spring, is, draws the arm 81 to its normal position, as therein shown.

There are times when it will be desirable to keep the roll 9 against the face of the roller 48 a longer time than is ordinarily desired, as more ink may be needed at some times than at others. To accomplish this feature I secure to the arm 84 a latch, Z, which is adjusted against a stop-pin on the fountain 78. I am enabled, therefore, to so regulate the travel of the rolls g and g that the former roll may only touch the face of the roll 48, or may bear against the face of said roll a short period after it has commenced its travel toward the inking-rollers 41.

In conjunction with the adjustable stops 19 on the movable type-beds, which, as before stated, are designed to check the downward movement of the papercarriage, I employ suitable chases, I of a construction substantially as shown in Fig. 9, wherein the chase is illustrated as having a thin curved plate projecting from its lower end. The said plate is formed of finely-tempered spring metal, and

is bolted or otherwise secured to the chase. The lower end of the plate rests against the base of thetype-bed, and being curved necessaril y throws the upper portion of the chase outward when the chase is first inserted. Then the operator forces the upper end of said chase back to its seat against the type-bed, and locks it rigidly in this position by any suitable means, thereby insuring the firm bearing of the chase against thetypebcds. This manner of locking the chase is not shown, as any well-known mechanism maybe employed; but the construction of the chase is clearly set forth in the figure before mentioned.

The press as now described is a duplex press, and is adapted to print two different impressions during each of the oscillating movements of the press. Thus I am enabled to print separate sheets or print from webs. If the operator desires to printfrom a web, he must employ some means for holding the web so that it will feed regularly, and also adopt a suitable mechanism for severing the web after theimpression is made. These important features I have accomplished, and the mechanism to be hereinafter described are designed to be a portion of the press, although they may be removed to change the web to individual sheet-printin g.

In Fig. 1 I have illustrated apress, showing a web upon one side, while the opposite side is designed for separate sheets. Therefore on the side on which the web is located I have mounted the web-holding and paper-cutting devices, it being manifest I may remove these mechanisms and use both sides of thepress for ICC ITO

sheet-printing, or may attach to the side which is shown as adapted for sheet-printing webholding and paper-cutting mechanisms corresponding to those on the opposite side. To accomplish these several results I attach to the top of the frame A a double-inclined bracket or shelf, Q, upon which the webholding devices are secured and which may form the feeding-table for separate sheets when used for that purpose. Upon this bracket is removably secured a frame, R, in the top of which a shaft, r, carrying the ,web S, is mounted. The frame R has aprojecting arm, which furnishes the fulcrum for a suitable lever, T, the lower arm of which has adj ustably secured thereto the upper end of a rod, U, whose lower end is attached to the pin on which the end of one of thelinks 7 is attached. The upper end of the lever T is slotted and carries a weighted depending pawl, V, which is adjusted on the lever by means of a handscrew, 8, passing through lugs 16 t on the lever and upper portion of the pawl.

On one end of the shaft r is mounted a ratchet-wheel, a, and a pulley, to, over the face of which is passed a strap, or, having a weight attached thereto, to prevent a too rapid feed of the paper. In addition to the pulley w, the shaft r carries a pulley, y, that 1s engaged by a curved portion, T, on the lever T, and serves as a brake for determining the rotation of the web. From the arrangement of these parts it is manifest the movement of the frame 13 toward the platen carries with it the rod U, which, being attached tothe-lower arm of the lever T, forces the upper end of said lever T and adjustable pawl V downward, and until the curved portion T of said lever comes against the periphery of the pulley g1, and thereby stops the unwinding of the web, this movement occuringjust prior to the moment the impression is made. As the frame B moves away from the platen the rod U draws upon the lower end of the lever T,

, and raises the upper end of said lever away from its contact with the periphery of the pulley y. At the sametime the notched end of the pawl Vcomes in contact with the ratchetwheel a and imparts to the web S a rotary motion, thereby unwinding said web, the amount of feed being accomplished by the adjustment of the pawl V and suitable devices beneath the web, which take up the surplus slack, thus always permitting the web to be held with sufficient tension to keep the paper in condition to be successfully operated upon by the paper-carriage.

Beneath the web S, and mounted between the sides of the frame R, are suitable devices to regulate the tension of the web as it leaves the roll. These devices consist, essentially, of the small rollers a and c, the latter being mounted in a weighted lever, d, fulcrumed at b on the frame It. Other rollers, e and g, (the former is mounted in a weighted lever, h, and the latter in a small bracket projecting from the platen-frame,) constitute the tension device, the'web in its delivery from the roll passing under the roller a, thence over roller 0, and finally between the roller 6 and 0 g, after'which it passes over the face of the platen and between the nippers 31 and 32 of paper-carrying devices.

After the impression has been made, the web is drawn downward by the nippers taking hold the paper again at or near the top of the platen-frame, and is subjected to the action of a suitable cutting apparatus, which severs the web and deposits the sheets upon a table suitably placed beneath the cutting apparatus.

The cutting mechanism is illustrated on an enlarged scale in Figs. 10 and 11, and comprises a plate, A, which is bolted or otherwise secured to the inside of the main frame A, and is provided with a channel or guide, B, in which are adjusted vertically arms 0, that have attached to them a knife or cutter, D. Screws E, operated by a hand-wheel, F, and miter-gears G G, pass through lugs on the back of the arms 0 and adjust said arms to correo spond with the size of sheet to be severed. The arms 0 are also provided with grooves H, in which slides the reciprocating plate I, having a knife or cutter, I, secured thereon, the said plate having extending ends 43, that are perforated to receive the ends, of rods k, which project from lugs Z on the side of the arms 0. Between the lugs Z and ends 6 and around the rods 70" are placed springs m, which retract the knife or cutter 1 after the I 0 paper has been severed. The lower ends of the arms, 0 have fulcrumed therein a lever,

K, provided with arms a, which pass through openings 0 in the plate I, and the lower arm of said leverK has pivoted thereto a pawl, L, which is engaged and operated by a catch, M, on the swinging frame 13. This catch is made adjustable on the frame 13, to correspond with the adjustment of the arms O, and is designed to engage the pawl during the move- I 0 ment of the frame B. Thus, as the frame 13, which, as before described, carries the typeform, moves forward, it carries with it the catch M, which engages but rides past the notched end of the pawl L. On the return of the frame, 5 and after the impression has been made, the notched portion of the catch engages the notched end of the pawl and draws upon said pawl. This action operates the lever K and forces the plate I, carrying the cutter I, inward, I20 thereby severing a portion of the web. The continued outward movement of the frame causes the catch to disengage itself from the pawl, when the latter is returned to its normal position by the spring N and stop ,0, and 5 is in condition to be operated upon again during the succeeding movements of the frame.

I am thus enabled to automatically sever the web and to adjust the cutting apparatus to cor-- respond to the size of sheet to be printed. I 3
