SPECIFICATION forming part of Letters Patent o. 568,904, dated October 6, 1896.

Application led July 1, 1895. Serial No. 554,556. (No model.) Y

To all whom it 11m/y concern:

Be it known that I, HARRY J. HEIMBERGER, a citizen of the United States, residing at Co'- lumbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Printing-Machines, of which the following is a specication.

My invention relates to the improvement of printing-machines; and the objects of my invention are to provide a power printingmachine of improved construction and arrangement of parts which will be particularly adapted for the printing of cards, small circulars, and similar work,which is ordinarily accomplished by hand-fed presses g to provide means for automatically feeding the paper into position for receiving the impression, and to provide in conjunction therewith improved means for cutting the paper into desirable lengths; to Aprovide improved guides for the paper, and to produce other improvements the details of construction and operation of which willbe more fully pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanying drawings, in which- Figure lis a side elevation of myimproved printing-machine. Fig. 2isaplan View. Fig; Irl is a central longitudinal section taken on line .r a: of Fig. 1L. Fig. ai is adetail planview of one ofthe paper-guides. Fig. 5 is an end elevation of the machine. Fig.- 6 is a vertical section taken on line y y of Fig. l; and Fig. 7 is a detail view of the type-chase, showing the same in position forinking the type.

Similar letters referto simi lar parts th rou ghout the several views.

In carrying out my invention I employ a suitable base, preferably of the oblong form shown at a.. a" represents a standard which rises, as shown in the drawings, from the base a, near the center of the length of the latter and on one side of the center of the width thereof. This standard has its upper end portion extending substantially at right angles with its vertical body, and the upper arm portion of said standard has fulcrumed thereto, as indicated at CL2, the central portion of a walking-beam c3, the latter extending in the direction of the length of the base a.. From the upper side of the rear portion of the base o extends upward a bearingstandard 0.4, and journaled in a boxing at the head of said standard a4 is a power-shaft b, said power-shaft carrying on one of its ends a belt-wheel t and on its remaining end a larger driving-disk b2.

b3 represents a connecting-arm, the upper end of whichis jointedly connected with the rear end of the walking-beam d3 at a point above the disk b2, and the lower end of which is secured on a pin b4, which projects 'eccentrically from the face of the disk b2. The pin b4 also has secured thereto one end of a crank-arm b5.

c represents awalking-beam of less length than the beam d3, said beam c being fulcrumed at a point in its forward half, as indicated at c, to the outer end of the upper arm of the standard a As indicated in the drawings, the forward portion of the beam c is bent out of alinenient with its remaining portion, said outwardly-projecting beam portion being parallel with the line of extension oi` the rear portion thereof. The rear end of the beam c is by means of a connecting-bar c2 jointedly connected with the outer arm of the arm b5, as indicated at c3. This outer arm of said arm is provided, as indicated in the drawings, with a number of pivot-pin openings c4, thus admitting of the connection of the bar c2 being made with said arm at dit'- ferent points.

Supported on the forward end portion of the base a is a vertical housing or casing d, the sides of which are open, as indicated. The vertical sides of the casing or frame cl are provided with oppositely-located central vertical slots or m'ortises d',which form guides for opposite end portions of a transverse pin cl2, which project therethrough.

d3 represents atype-holding chase which is substantially of the cup shape shown and from opposite ends of the back of which project cam-plates d4. As indicated in the drawings, each of these cam-plates d? is substantiallyof an acorn shape and has its outer end portion on opposite sides of the center of its width provided with inwardly-extending and inwardly-curved recesses d5. Each of the cam-plates d4 thus formed has its inner portion at a point adjacent to the back of the chase d3 mounted centrally on the pin d2, which extends through said casing or frame cl.

ICO

Z9 represents two horizontal pins which are arranged one above the other and which eX- tend between the end plates of the casing d, said pins being adapted, as shown, to pass loosely through the guide-recesses d5 of the cams d4 when the type are in the inking position hereinafter described.

Against the under surface of the upper side of the casing (l I provide a suitable pliable pad or facing d6, and in the base t beneath said casing d I provide a pad C17, the upper surface of which is flush with said base ct.

As indicated at d8, the under side of each of the vertical end platesv of the casing cl is slightly cut away or recessed to form, as hereinafter shown, guideways for a paper strip.

To the walking-beam CL3, at a point over the casing d, is pivoted the upper end of a connecting-bar e, the lower end thereof having, as shown at e', a pivotal connection with the upper end of a vertical plunger-rod e2, said plunger-rod extending downwardly through a keeper or guide e3 on the upper end of a standard e4, which rises from the base ca The lower end of this plunger e2 is secured to the upper horizontal arm of a yoke e5, the downwardly-extending parallel arms e6 of the latter embracing, as shown, 'the forward and rea-r sides of the casing d. The lower ends of these yoke-arms e6 are, as indicated at e7, connected with the outwardlyprojecting ends of the cam-supporting pins d2.

f represents a stationary knife-bar which, as shown in the drawings, is secured to the forward end of the base ct and has its upper beveled and sharpened edge project-ing in front of the forward guide-opening d8 of the casing d.

'lo the extreme forward end of the walkingbeam a3 is pivoted at f' the upper end of a knife-operating bar or arm This bar f2, which extends downward, is inclined slightly outward and has its lower end pivoted at a point f3 to one end of a knife-bladef4, the remaining end of said knifeblade being pivot-ally connected atf5 to the outer face of one end of the knife-bar The lower edge of the bladef4 is sharpened and adapted, when moved upward and downward on its pivotpoints, to shear against the sharpened upper edge of t-he fixed barf. The knife parts thus formed are loosely embraced by a forwardlyprojecting keeper-rod f6.

From each of the vertical end plates of the casing d, adjoining the upperend of thelatter, project oppositely-located hracket-arms g, in the outer ends of each pair of which are journaled the end spindles of a roller g', and these rollers` g' carry, as shown in the drawings, an endless ink-belt g2, the lower line of the latter passing through the upper end portion of the casing d in contact with or adjacent to the under side of the pad d, Rising' from the base-plate a, at a point in front of the driving-disk b2, are two oppositely-located standards h. Each of these standards is provided with a horizontal foot portion h', through which is adapted to pass a bolt h2, said bolt passing downward through a block h4, which is formed with the under side of the foot, and which is adapted to slide in a transverse Way h3, formed in the base ct, said base being also provided with a transverse slotted opening h5 beneath said block through which the bolts h2 are adapted to project, as shown in Fig. l of the drawings. These bolts are adapted to receive nuts h6 in the usual manner. standards h are adapted to be detachably journaled the spindle ends t7 of a roller h, on which is adapted to be mounted a roll of paper hf. The upper ends of the standards h above the paper roll are connected by a transverse shaft hw, and on the center of said shaft is loosely mounted the upper end of a tension-arm h, the latter curving downwardly and having a transverse foot portion k12, which is adapted to bear againstthe surface of the paper roll hg. The foot of the tension-arm is caused to exert the desired degree of pressure against the paper-roll surface through the influence of a spring hls, which has one end secured to and which is coiled upon the shaft IL10, and which has its remaining end bearing on the upper side of the` arm hu.

From the upper side of the base Ct, ata point adjacent to the rear -side of the casing d, I provide two upwardly-projecting oppositelylocated standards z', in which are journaled the end portions of a transverse shaft This shaft 2 carries between said standards a coniparatively large feed-roll t3. The shaft i2 also carries adjacent to one end of said feed-roll a ratchet-wheel 114, and pivoted on said shaft on the outer side of said ratchet-wheel is one end of a forward ly-extending arm t5, the outer end of the latter being jointedly connected with the forward end of the walking-beam c by a connecting-bar i6. To the inner side of the arm i5 is pivoted a pawl't'?, which is adapted to engage with the teeth of the ratchet. i4, as

In the loo IIO

shown more clearly in Fig. l of the drawings.

The opposite end portion of the shaft 712 projects beyond the bracket in whichit bears and carries, as indicated at is, a gear-wheel, the latter engaging with the teeth of a gearwheel j, the upper portion of which projects upward through a slotted openingj in th`e base ct. The gear-wheel j is mounted on a transverse shaft jz, which is journaled in bracketsj' which depend from the under side of the base tt. This shaft l7'2 also carries a transverse roll ji the upper side of which projects through the base d and is normally in frictional contact with the roll t3.

In front of the paper roll is journaled in suitable short brackets, which rise from the base-plate a, a small feed-roll lo, and on opposite sides of the roll t3 I support on saidbase-plate adjustable paper-guides k'. In

con structing each of these paper-guides I provide a transverse mortise k2 in the base a, and into this mortise are inserted two guideblocks 7a3, the latter being provided with anged upper sides,as indicated at 7t'4,adapted to span the mortise k2. These guide-blocks have their upper sides provided with inturned flanges h5, from which rise lugs k6, each of the latter having a threaded opening therethrough. The lugs lo are adjust-ably connected by means of a horizontal adjustingscrew k7, having a suitable thumb-piece ks on its outer end. This adj Listing-screw is provided for one half of its length with a righthand screw-thread and in its remaining half with a left-hand screw-thread, as indicated more clearly in Figs. 2, 3, and 4 of the drawings. The under side of each of the blocks k2 has secured thereto by means of a screw kf a washer or cross-piece lam of greater width than the width of the slotted opening k2.

Supported on the base ct at one side of the casing d are two oppositely-located vertical standards m, the upper end portion of each of which terminates in two or more radiallyarranged arms my'. These arms m of the two standards m, being oppositely located, form bearings, as shown, for the end spindles of ink-distributing rollers m2, the latter being in frict-ional contact with a large ink-rollermi, mounted upon a shaft w14, which is journaled in the standards m. This shaft 'm4 also carries on the outer side of the arms m a ratchetwheel m5.

n represents a lever-bar, one end of which is fulcrumed on the shaft m4 and the remaining and slotted end of which receives a pin W, which projects from the arm f2 at a point near the lower end thereof. The lever-bar n has pivoted thereto a pawl 0, the free end of which is adapted to engage with the teeth of the ratchet m5. The lower portions of the standards m are provided with 'oppositelylocated arms p, between which is journaled an ink-roll p', one end of which carries a gearwheel p2. Beneath the ink-rollp is supported On the base a an ink reservoir or box p3, within which is journaled an iuk-rollerp4, said inkroller carrying on the outer end of its shaft a pinion-wheel which gears with the wheel p2. As indicated, the peripheries of the rolls p4 and p are in frictional contact. It will be observed that the endless inking-belt gZ is, while passing over one of the rolls g', in frictional contact. with the large in king-roll m3.

The operation of my im proved printingmachine is substantially as follows: The type q are set and secured in the chase d3, the printing-faces of said type projecting beyond said chase. The end of the papel' roll iscarried downward beneath the roll k, threaded through the rear guide k', between the blocks k and beneath the flanges k thereof, and then carried between the rolls jd and t3. From these rolls said paper strip is passed between the guide-blocks of the forward guide k' and thence through the oppositely-located openings d8 of the printing-case d, from which said strip leads out over the fixed knife-bar f and keeper f6. Through the medium of a suitable engine-belt motion is imparted to the wheel b', which through its shaft b imparts a rotary motion to the driving-disk b2. The rotation of this disk results, as is evident,

vfrom the connections therewith heretofore described ot' the bars-b3 and c2, in an alternate rocking action of the walking-beams d3 and c. As the walking-beam bar 'i6 executes its lupstroke it is evident that the engagement of the pawl 7 with the ratchet i4 will result in said ratchet being turned in the direction indicated by the arrow adjacent thereto a suflcient distance tol allow said pawl to drop into engagement with the next succeeding tooth of the ratchet. This movement of said ratchet results in a corresponding rotation of the feed-roll t3, and through the engagement of the gear-wheels j and fis motion isimparted to the roll ji. In this manner the paper strip which leads from the roll b9 is fed forward through the casing d a distance equal to the width or length of the card or other paper to be produced. While thepaper-feeding rolls thus described are at rest during the downward movement of the bar '126 the forward end of the walking-beam a3 descends and through its descent the connections of the knife-operating bar f2, lever-bar fn, and engagement of lthe pawl o with the ratchet 'm5 a partial rotation of the large inking-roll In3 is attained. Through the frictional contact of the ink-rolls m3, p', and p4'and the gear connection of the wheels p2and p5 rotary motion is imparted to said rolls p' and p4 and the ink, which is taken up by the roll p4 from the reservoir p3, in which it travels, is conveyed to the roll p and thence to the larger roll m3, where it is equally distributed from the frictional contact with the rolls m2. As indi- IOO IOS

cated, the gears p2 and p5 are preferably of i dilferent sizes to impart increased distribution ot' ink. The frictional contact of the continuous inking-belt g2 with the surface of the roll m3 results in not only supplying said belt g2 with ink, but in imparting a traveling motion to said belt over its rollers g. In addition to the operation above described the downward movement of the forward portion of the walking beam (t3 results in a downward movement ofthe plunger c2 and in a consequent downward movement of the arms e5 of the chase-operating yoke e5. When the yoke is in its elevated position, it is evident that, owing to the connection of the pins d2 with the cams d4, the chase will be supported horizontally in the upper portion of the casing d, with the type-faces in contact with the inking-belt g2, and that the lower guide-pins dg will be disengaged from one of the cam-recesses d5, while the upper guidepinv (Z9 will be at the inner ends of the remaining cam-*recesses d5. The downward movement oi' the yoke hereinbefore described must however result, through the engagement of said upper pin d'9 with the recesses of the camplates, in turning the chase to the half-inverted position indicated in Fig. 6 of the drawings, in the engagement of the lower IIO IIS

pins d with the remaining recesses of the cam-plates d4, and, finally, in a complete inversion of said chase. In this position it is evident that the faces of the type which have been inked by Contact with the belt g2 will be pressed into contact with the paper strip, which is temporarily at rest beneath the chase on the pad di. A further result of the downward action ofthe forward end of the walking-beam c3 is the downward shearing movement of the knife-blade f4 against the side of the knife-bar f, with the result that that portion of the paper strip on which a previous impression has been made and which, by means of the feeding mechanism hereinbefore described has been fed through the forward guide-opening d8, is cut off and dropped from the machine. The succeeding upward movement of the forward portion of the beam CL3 must, as will readily be seen, return the typechase to its upper or inking position, lift the knife-blade f4, and raise the pawl o into engagement with another tooth of the ratchet m5, thus placing said parts again in position for operation on the downstroke of said walking-beam.

From the operation described it will be seen that the feeding of the paper from the roll and inking of the inking-rolls and type is accomplished simultaneously and that the printing and cutting operations are alternate therewith.

Owing to the use of the spring-actuated tension-arm hn the paper on the roll hs is held against too rapid removal. In case it is desired to vary the width of paper used, it is evident that by turning the right and left hand threaded screws k7 of the guides 7c one of the guide-blocks may be rigidly connected with the base-plate by turning upward one of the screws le" until its washer 71:10 is clamped firmly against the under side of the bed-plate, after which the remaining guide-block may be forced toward or from the other, as may be desired, resulting in the formation of a space between said blocks equal to the width of the paper to be passed therethrough. By varying' the point of connection of the bar c2 with the outer arm of the arm h5 it is evident that the extent of rotation of the feedrolls will be varied and that the lengths into which the printed paper strip is cut may thus be regulated.

From the manner hereinbefore described of securing the paper-roll standards on the base a it is evident that by loosening the bolts h2 the block extensions h4 of said standard-feet may be moved inward oroutward in the guideway h3, thus providing for the support of paper rolls of varying widths.

From the construction and operation which I have described it will be seen that simple, reliable, and effective means are provided not only for producing rapid and regular printed impressions, but for automatically feeding the paper through the printing-case and cutting the same into desired lengths.

It is evident that a printing-machine such as herein shown and described will be of great utility in the printing of cards, small circulars, the., which ordinarilyT are produced on handfed machines or presses.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a printing-machine the combination with a base a, having a mortise 7a2 therein, a paper-roll-carrying reel mounted on said base, a spring-actuated tension-arm pivotally connected with the roll-supporting frame and adapted to bear against the roll, coacting feed-rolls journaled in front of said paper roll between which the paper strip from said paper roll is adapted to pass and means for imparting an intermittent rotary motion to said feed-rolls, of guide-blocks k3 movably supported in said base-mortise k2 between said paper and feed rolls, an adj Listing-screw k7 connecting said guide-blocks, said screw having a right-hand threaded engagement with one of said blocks and a left-hand threaded engagement withthe other, means for producing a temporary rigid connection of one of said' guide-blocks with the base, and a printing mechanism in line with the feed-rolls, substantially as and for the purpose specified.
