PRINTING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 489,981, dated January 17, 1893. Application filed June 22, 1891. Serial No. 397.132. (N model.)
To all whom it may concern: Be it known that I, ALFRED C. NORTH, a citizen of the United States, residing at Benton. Harbor, in the county of Berrien and State of Michigan, have invented a new and useful Improvement in Printing-Machines, of which the following is a specification.
My invention relates to improvements in oscillating printing presses generally; though more particularly to an improvement in a printing machine in which an oscillating press designed to print upon a continuous web of paper, forms a part of the machine which is also provided with mechanism for severing the web, after it has been printed, into sheets of desired size.
In the drawings-Figure 1 is a side view of a machine embodyingmyimprovements; Fig. 2, an enlarged sectional View taken 011 line 2 of Fig. 1, and showing the printing press in side elevation; Fig. 3, a top-plan view of the platen,its pivotal supporting lever, and adja cent guide for the web; Fig. 4, a broken sectional plan View taken on line 4-4 of Fig.2, and viewed in the direction of the arrows; Figs. 5 and 6 sections taken respectively on lines 5 and 6 of Fig. 2, and viewed in the direction of the arrows; Fig. 7, a section taken on line 7 of Fig. 2,'and showing two 0 inking tables; Fig. 8, a broken view illustrating in elevation the gear connection between the printing-press and driving'shaft of the machine; Fig. 9, a bottom plan view of an inking table; Fig. 10, a broken View in eievation of cam mechanism for giving an oscillatory motion to the inking table; Fig. 11, a section taken on line 11 of Fig. 1, enlarged, and showing the feed mechanism for the web in side elevation; Fig. 12, a sec- 40 tion taken on line 12 of Fig. 1, enlarged, and showing the cutting mechanism for severing the web into sheets; Fig. 13, a broken view showing the web feeding mechanism in front elevation; Fig. 14, abroken perspective view of the guide for the web; Fig. 15, an enlarged broken perspective View of the inking-table, and the operating mechanism therefor to effect proper distribution of the ink; Fig. 1G, a bottom perspective view of one part of the inking-table; Fig. 17, a side View of the inking-table detached from the machine; Fig.
18, a bottom perspective View of the rotating and Fig. 19, a side elevation of the inkingtable bearing.
My principal objects are, first, so to secure the printing press upon the frame as to render it adjustable longitudinally and crosswise thereof; second, to provide for the employment of two or more of the printing presses upon the sa1neframe,geared toa common drive shaft, and adjustable with relation to each other upon the frame, to co-operate in printing upon the web; third, to provideasupport for the platen, hinged to the frame of the press in a manner which permits it to be easily displaced to give access to the bed of the press; fourth, to render the inking-rollercarriers so adjustable that their throw may be regulated to diminish or increase the distance .of travel of the rollers; fifth, to provide an adjustable system of gears between the drive shaft of the machine and the press, whereby the speed of the latter may be increased or diminished with relation to the other parts-7 5 of the machine and two or more colors or two or more forms be printed at one time; sixth, to provide an inking table of an improved construction, having a vibrating and a rotat-' ing platform to facilitate the distribution of the ink; and, lastly, to provide a printing machine of the class named, which shall be of a comparatively simple, cheap and durable construction, adapting it to general use in a printing office.
A is the frame of the machine, provided with the supports A A suit-ably braced, as shown. At the top of the frame are two horizontally extending and parallel side-rails A A affording a track upon which the various features of the machine are adj ustably mounted, as hereinafter described.
B is a drive-shaft extending longitudinally of the frame, having its bearings in brackets in the sides of the supports A A and pro- 5 vided at one end with a friction disk B.
On the end of the frame A is a cross-shaft B carrying at one end a power pulley B and at its opposite end-portion a longitudinally adjustable friction pulley B. The shaft B Ioo is journaled in a movable frame between which and the main frame is suitable shipping mechanism operative at will to throw the friction pulley B into and out of engagement with the disk 13, and thereby produce or stop rotation of the shaft B.
O is the frame of the printing-press which is mounted on a sliding support 0. The frame 0 comprises a base formed of two parallel bars t, firmly bolted together, provided with corresponding rigid uprights s at their rear ends, and corresponding rigid brackets 'r at their forward ends, each bracket being formed with a downward inclined arm r,carrying an upward extending arm 0*, as shown.
On opposite sides of the base-barf at the forward ends of the latter are vertically slotted adjusting plates 1, held against the base-bars by set-screws q, and resting upon the support 0 at the rail A. Resting across the bars 25 is a loose clamping plate t, affording a bearing for a clamp-screw 25 which passes down between the bars 15 into a threaded opening in the support 0'.
Extending at its ends against the undersides of the rails A A, is a loose clamping plate to, affording a bearing for a clampsorew to which passes upward through the plate 10 and between the rails A A into a threaded opening in the support O. The support 0 may he slid along the rails A A and secured in adjusted position by tightening the screw w which causes the rails to become firmly clamped between the support G and plate w; and the frame 0 may be adjusted by sliding it longitudinally upon the support 0, in a direction crosswise of the machine, and when adjusted it may be fastened rigidly in position by tightening the screw 23 which causes the bars 25 to become firmly clamped between the support 0 and plate 15.
Journaled in the brackets 4" is a shaft 1) carrying a speed altering gear, comprising a series of three cog-wheels p 12 19 of varying diameters; and on the shaft B are three adjustable cogwheels, 0 0 0 of varying diameters, which maybe tightened and loosened on their shaft by means of set screws and slid respectively into and out of mesh with the respective cog-Wheels p 19 19 Thus, for example, the wheels 0 and 19 may be of equal diameters whereby when they are caused to engage, the shaft 1) will be rotated at the same speed as the drive-shaft B. The central wheel 0 is of smaller and the wheel 19 of larger diameter than the wheels 0 p whereby when they, instead of the central gears, are caused to engage, the shaft 19 will rotate more slowly than the shaft 13. The wheel 0 is of still smaller and the wheel 1) of still larger diameter than the central wheels, and when they, instead of the others, are brought into mesh, the rotation of the shaft 1) will be correspondingly slower than that of the shaft B. In practice the relative sizes of the cog-wheels should be such that engagement of the wheels 0 19 will cause the shafts B and p to rotate with equal velocity, engagement of the wheels 0', 19 will cause the shaft 19 to rotate with half the velocity of the shaft B, and engagement of the wheels 0 ,19 will cause the shaft 13 to rotate with one-third the velocity of the shaft 13.
When a changing of the gearing, as described, between the shafts B and'p necessitates the increasing or decreasing of the distance between those shafts, this may be effected by adjusting the frame of the press higher or lower in the slots q of the supporting piates q. vAt opposite ends beyond its bearings the shaft 19 carries crank arms 19 extending in the same radial plane.
D is the bed of the press, on a rocking bed frame D havin arallel rearward extendin arms at at the ends of which it is pivoted upon a shaft m extending between the uprights s, and parallel forward extending arms l. At the end of each arm Z the bed-frame is connected by a pitman 7a with the crank 19 on its respective side of the frame, whereby in the rotation of the shaft 19 the bed-frame is rocked on its pivot in the vertical plane. Extending downward and backward from the bed frame are rodsz' which in the oscillation of the bed-frame reciprocate through a guide t" on the frame 0. Coiled about the rodsi and confined between the-bed-frame and the stirrup end 1' of the guide are springs i which resist the lowering and assist the rise of the bed-frame, and their resisting power may be so regulated as to produce a counter balance for the bed-frame. The stirrup end i of the guide, has a series of bolt holes 1', whereby it may be shortened'and lengthened to increase or diminish the tension of the springs, to regulate them, as described, and secured by bolts, in adjusted position, to the sides of the guide.
E is the platen, which is carried by a vertically swinging lever E. The lever E is bifurcated at its rear end portion, and at the ends of the forks it is pivoted upon the shaftm on the support 3. At its forwardend the lever E is formed into a handle h, and when the lever is swung down to the position shown by full lines in Fig. 2, it rests near its handleportion upon a shaft g which extends between the arms 1' of the support or bracket frame r. On opposite sides of the lever E near the point of its contact with the shaft g are lugs h. Fulcrumed upon the shaft g at opposite sides of the lever E, is a bifurcated lever E having the end of its long and heavier arm formed into a handle, and the ends of its short arm formed into hooks to engage the lugs h, and lock the lever E down against the shaft g. The hooked ends of the lever E fit closely over the lugs h, and, while they may be readily disengaged by raising the le ver F at its long-arm, when in engagement with the lugs, they produce a lock which holds the lever E in place with great rigidity.
Upon the sides of the lever E are lugs 7L2 affording bearings for set screws h and the platen is provided at the center of its upper side with a threaded rod 7t which extends upward through an opening in the lever E. Above the lever E the rod 71. is providedwith a nut 7&5 between which and the lever is confined a stiff spring 71. which operates to holdthe platen up against the lower ends of the set screws 7L3. By means of the set screws ]L3 the platen may be adjusted with great accuracy.
To give access to the bed for the purpose of inserting or removing a form, the lever F is turned to disengage the lugs h, and the lever E is swung upward on its pivot to the position indicated by dotted lines in Fig. 2, where it is stopped from swinging farther by contact of a projection 71 on its end with a lug s on the upright s.
F F are adjustable web sustaining guides having longitudinally slotted arms f, through which they. are secured by thumb-screws f to opposite sides of the bracket-arm, W, and arms f which are adjusted to extend in a plane parallel with, and the thickness of the web below, the platen, at opposite sides of the latter.
The ink supplier which I prefer to provide in the form of inking table G is mounted upon a lever G, which is pivotally connected to a bearing Z secured to a bar Z extending between the arms Z of the frame D. The lever G and inking-table oscillate from right to left on the bearing 1.
Mounted between the bracket arms r is a plate 6 having flanged edges 6 e Midway between its edges the plate is provided with a stationary cam e pointing downward, and, just below the cam e with a pivotal pointed switch 6 having its pointed end upward and a wide end below the pivot. A spring a is connected at. one end to the center of the plate e below the switch, and at its opposite end, through the medium of the rod 6, pivotally to the switch near the point of the latter. The spring resists turning of the point of the switch from either side toward the center of the plate, and causes the point when turned from either direction past the center to spring to the adjacent side of the plate 6. The forward end of the lever G extends between the sides e e of the plate 6, and in its downward oscillation strikes the switch and turns it. In its upward oscillation the end of the lever G moves the switch, without turning it past its center whereby it springs back to its former position, and operates when the lever descends again to direct it across to the opposite side of the plate e. Thus in operation, as the bed-frame falls and rises the lever G descends along the side 6 for example, is directed by the switch across to the side e, turns the switch, ascends along the side e, then descends again along the side c, is directed across to the side 6 turns the switch and rises on the side e &c.
The inking table G, comprises a platform 6 firmly secured to the end of the lever G and a rotary disk a pivoted on the lever at e. The disk and platform fit together as shown to produce a substantially continuous table. On the underside of the disk a is a circular rack e Pivoted upon the sides of the bearing 6 on the lever G is a lever 6 having a long arm, which extends beyond the edge of the platform e and carrying a pawl e which engages the rack 6 The pawl e is pivoted loosely upon the end of the short arm of the lever 6 and rests at one end against a pin e carried by the latter, all as clearly shown in Figs. 15'and 17. On the plate 6 in the path of the long arm of the lever e is a projecting plate 6 against which, in the descent of the bed-frame, the lever strikes and is thereby turned upward on its. pivot. As the lever e strikes the plate e and swings upward, its pin e turns the pawl e causing the latter to engage a tooth of the rack e The engagernent of the pawl with the rack is in the nature of an impact, which drives the disk 6 around causing it to rotate upon its bearing and wipe across the pawl, until stopped by friction or the engagement with it of the inkrollers, as hereinafter described.
Extending downward from opposite sides of the bed-plate D are arms D and pivoted between their ends at (Z to the lower ends of the arms D are roller-carrying levers H. Below the pivotal connection d each lever H is bent, as shown in Fig. 2, and provided with a slot (1 in its end. On each side of the support 0 is a downward extending arm O affording at its lower end a bearing for a forward extending longitudinally slotted rod d The rods d are pivotally secured through their slots to the bearings by cap-screws (Z being adjustable thereon longitudinally to the extent of the length of their slots, and they are pivotally secured in adjusted position against longitudinal movement by tightening the cap-screws. At their opposite ends the rods (1 are pivotally and adj ustabl y connected with the levers II at the slots (1. The rods (1 by swinging upon the pivots at (F, thus afford shifting fulcrums for the levers H. The rollers H are mounted at their ends in bearings c on the ends of reciprocal rods 0, in a common manner, the rods 0' extending through guides on the levers H, and held down by springs 0 The rollers H travel 011 tracks 0 at the sides of the bed, and the tracks are provided at their ends with slots 0 through which they are secured to the bed by cap screws. The tracks may be raised and lowered to an extent limited by the length of the slots 0 whereby they may be adjusted to compensate for shrinkage of the rollers.
In operation, the rise of the bed frame rocks the arms D in a forward direction causing the levers H, owing to their pivotal engagement with the rods 01 to be oscillated forward on their pivots d, to swing the rollers across the inking table; while the descent of the bed frame causes the lovers H to be swung backward to carry the rollers across the form. By changing the adjustment of the rods 61 in the slots cl of the levers H, the throw of the levers H maybe regulated to anydesired degree; and by changing the adjustment of the rods (1 on the arms 0 the terminal points between which the rollers travel may be regulated. Thus the rollers may be caused to travel entirely or only part way across the inking table and the bed. As the distance through which the rollers are required to travel determines the speed at which the press maybe operated,this adj ustment,whereby the sweep of the rollers maybe limited, is particularly desirable, because it renders possible speeding of the press, much more highly than otherwise, on small job work, such as tags, the forms of which need be caused to occupy only the forward part of the bed. In the downward oscillations of the bed-frame, after the rollers haveleft the inking table, the forward end of the lever G strikes the switch e and is moved as described, causing the inking table to be oscillated alternately to the right and left, and thus facilitate the distribution of the ink.
In the construction, shown in Fig. 7, two adjacent lying oscillating inking tables G and divided inking rollers H are provided, for printingin two colors. The tables are'mounted upon the bed frame, and a plate 6, constructed as above described, is provided upon the bracket frame 7" for each lever G to move in. The operation of each table is the same as where only one table is employed, as described. The plates e are removable and replaceable, and so are the inking tables, whereby the single table and double table may be interchanged on the same press.
On the shaft B in Fig. 1 is shown a second set of gear wheels 0, 0, 0 to which a second press, constructed like the one described and mounted on the frame A in the same manner, may be geared.
1 is an adjustable intermittentfeed mechanism for the web Z, mounted upon a sliding support I, like the support 0 of the press, whereby it may be moved toward or away from the press on the frame A, and secured in adjusted position. The frame of the feed mechanism comprises two uprights I and I joined together by a cross piece I, and to the top of the upright I is pivoted an arm 1 Mouned in hearings on the upright I is a loose shaft 03 carrying a cog-wheelm. In bearings on the cross piece I is a loose shaft :0 carrying a pinion 00 which meshes with the cog wheel as, and a feed-roller m A loose shaft a, mounted in bearings on the arm 1 carries a friction roller 00 which is pressed against the roller 50 by a spring 00 interposed between the arm I and upright I beyond their pivotal connection. Also upon the shaft 00 are a removable and replaceable ratchet-wheel a which is tightened upon the shaft, and a spring pawl no which engages the teeth of the ratchet-wheel. The lever 05 is connected by a removable and replaceable link 00 with an eccentric I on the shaft B. The eccentric I may be adjusted along the shaft B, and is of special construction, described and claimed in a separate concurrent application for Letters-Patent. It may be adjusted to increase or diminish the throw of the link 00 and lever w in such a way that the degree of rotation transmitted by the pawl to the ratchet wheel and through the latter to the rollers 11: or, with each revolution of the shaft B, may be regulated with great precision. The degree of rotation of the rollers with each operation is regulated by the distance of throw of the lever 00*; hence, when the lever and ratchet-wheel are on the shaft :0 as shown, the web Z can only be caused, in each revolution of the shaft B, to travel adistanceless than one-half the circumference of the roller x WVhile this would be sufficient for small job work, larger work would make it necessary for the web to travel much farther with each operation than is possible with the adjustment described. For larger work the ratchet wheel and pawl-carrying lever may be removed from the shaft 00 and placed upon the shaft or, the lever being connected to the eccentric by a shorter link than the one shown. When thus adjusted the cog and pinion gearing between the ratchet-wheel and feed-rollers will cause the distance of travel of the web to be increased; and it may be regulated, as before stated, by the adjustment of the eccentric.
K is the web-severing mechanism mounted upon a sliding support K for purposes of adjustment toward or away from the other mechanisms. It comprises a stationary cutting blade 22 mounted upon uprights 17' b and a vertically oscillating cutter-blade b pivoted at one end to the blade I) and operated from an eccentric on the shaft B, as shown, which may be adjusted longitudinally on the shaft.
L is an adjustable guide for the web Z mounted upon the frame Ajust in advance of the printing press. It comprises two uprights a (0' provided at the top with a vertically disposed plate a having a guide opening a through it for the passage of the web, and a horizontal plate a upon which are adjustable guide piecesa for the edges of the web. The roll Z from which the web Z is drawn, may be mounted between standards on the end of the frame, as shown, or in any other suitable location. The web passes from the roll through the guide L, thence through the printing-press, between the web sustaining guides F F and platen, to the feed-mechanism I, where it is clamped between the intermittingly rotating feed-rollers 00 azhand thence to the severing mechanism K.
The machine is capable of adjustment for thepurpose of turning out printed sheets of any size within the capacity of the press or presses- The relative speeds of the ditferis indicated by broken dotted lines.
mar the work turned out. The adjustments are positive and all of the simplest nature, thereby contributing to the desirability of the machine.
In Fig. 1 a second press upon the frame A 7 Then two presses are employed the feed I and websevering mechanism K would be adjusted farther along toward the rear end of the frame.
The relative adjustments of the presses and cutting device, as for sheets of different sizes, are effected by sliding one or both the presses and the cutting device along the rails. This permits the web to travel in a straight line through the machine, and enables me to dispense with the adjustable guide rollers usually employed in printing presses to regulate the distance of travel of the web between op erating mechanisms.
The adjacent lying and horizontally vibrating inking tables and divided inking rollers adapt the press, as stated, to color work. If desired, three or more inking tables, like those described, and made proportionally narrower, may be provided and mounted in the bed-frame to operate as set forth; and inking rollers divided into sections corresponding in number with the inking tables, should also be provided.
The adjustability of the press and feed mechanism with relation to the driving shaft renders it possible to print with several forms in each press, in several colors, and in any size sheets within the capacity of the presses.
'While I have shown and described only three pairs of gears between the printingpress shaft and shaft B, the gears may be increased in number, for further change in the ratio of movement, the increase being accompanied with the necessary change of size and number of teeth, so that the press maybe caused to give one impression with each four or more rotations of the shaft B. As the feed and cutting mechanisms operate once with each rotation of the shaft B, as many forms as the shaft B rotates times the press-shaft,'
may be placed side by side in the press, in the direction of the length of the web. The intermittentfeed mechanism may be regulated to carry the web forward a desired distance with each operation; and as many adjacent lying inking tables may be provided for each press as desired, all as before stated. Thus the machine is adapted to turn out many kinds of color-work, which maybe increased by increasing the number of presses upon the frame, and, if desired, by having the presses run at different speeds, as provided.
As an illustration of one class of work which my improved machine mayperform when, for instance, two presses are provided on the frame: the first press, printing on tint-blocks, may be caused to give one impression with each third revolution of the drive shaft B, and print as many tints as there are inking tables provided; and the second press may be caused to give an impression with each revolution of the drive-shaft, and print three forms in different colors 011 the tinted surface, the feed being regulated to move the web onethird the distance across a press with each operation. WVhen more than one press is provided upon the frame and arranged, say, to print in different colors on the same fields in the web (as for chromo work), any mistake in the relative adj ustment of the forms in the different presses may be overcome by simply adjusting the press longitudinally or crosswise of the machine, as provided by the construction, and thus save a great deal of time, which would otherwise necessarily be taken to unlock and readjust the forms in their chases.
