Specification of Letters Patent.

Patented Oct. 24, 1911.

Application filed November 11, 1908. Serial No. 462,130.

To all whom it may concern:

Be it known that I, GUSTAVE LIDsEEN, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Printing-Presses; and I dohereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The object of this invention is to afford a printing press of cheap and simple construction, in which the type are inked by means of a ribbon which is supplied with ink by an inking pad, thereby enabling the type to be very uniformly inked and permitting change in the color of the ink to be effected readily by the exchange of the pads and ribbons.

It is also an object of the invention to afford an exceedingly simple actuating means for operating the press, simultaneously actuating the inking pad and inking ribbon (as the case may be), and to afiord means for applying uniform and regulable pres- Fig. 1.

sure on the type in printing.

The invention consists in the matters hereinafter described and more fully pointed out and defined in the appended claims.

In the drawings: Figure l is a side elevation of a printing press embodying my invention. Fig. 2 is a viewin elevation ofthe.

opposite side of the press with the bed turned down. Fig. 3 is a central vertical section of the same. Fig. 4 is a reduced top plan view of the same. Fig. 5 is a perspective view partly broken away of the inking pad showing the same removed from the machine. Fig. 6 is a section on line 66 of Fig. 7 is an end elevation of the chase showing the same removed from the press. Fig. 8 is afragmentary front eleva tion thereof. Fig. 9 is an enlarged top plan view of a part of the inking mechanism and illustrating the ways for the inking rolls and the shaft. Fig. 10 is a section taken on line 1010 of Fig. 9. Fig. 11 is a section taken on line 11-11 of Fig. 9. Fig. 12 is an enlarged detail view of the latch for releasing the ribbon roll. Fig. 13 is a top plan view of the same. Fig. 14 is an enlarged section taken through the inking pad showing one of the push pins in elevation. Fig. 15 is a fragmentary detail illustrating a modification of the mechanism for applying pressure of the inking pad or ribbon on the type. Fig. 16 is a fragmentary top plan view of the same.

In the drawings said machine comprises a base A, having, as shown, an upwardly extending cast metal frame or standard integral therewith of suitable height and comprising side walls a, and connected at the top with the arched web a, and also connected by means of an integral fiat web a which inclines obliquely downward and rearwardly, as shown in Fig. 3, and is faced off to afford a plane surface to support the chase with the type therein.

Pivotally supported on a transverse shaft B,extending through said standard, is a movable bed or jaw B, also affording a flat face complemental with the flat face of the chase bed a and as shown, integrally connected at the lower edge of said bed or jaw B and projecting between the sides of the standard is a lever 72, through which the shaft B, extends. Side or cheek plates are integral with the jaws and extend outside the stand ard and are also apertured to receive said shaft. Adjustably secured on said bed or jaw B, by means of set screws 6 is a bed plate 5 upon which the paper rests in printprinting and as shown, clamping bars 5 one at each end of said plate, are provided and pivoted on a shaft 6 which extends through the lower ends of said clamping bars or fingers, and asshown, a lever Z), is secured on said shaft 5", and acts by gravity in part and a spring I) to actuate the clamping bars to hold the papers on the bed plate 72 andthe end of said lever I), engages on the base when the jaw is swung down to lift the clamping fingers from the printing face.

Journaled in a rearward extension A, of the press frame, is a horizontal shaft C. This, as shown, is operatively engaged by an actuating lever C, directed at right angles therewith and extending alongside of the press. Rigidly secured on said shaft, and fitting loosely in a suitable notch or space provided in the rear portion of the frame through which said shaft extends, is a toggle bar D, the lower end of which is pivotally connected with the upper end of a toggle bar D, which is pivotally engaged upon an eye bolt cl, threaded in the rear end of the lever 79, and as shown, is provided with jam nuts clcl so that upward movement of said lever C, swings the joint in said toggle levers inwardly, elevates the lever 12, and opens the press, while downward pressure on said lever tends to force said toggle bars D-D, into alinement to close the press and exert a printing pressure on the type.

Journaled upon the shaft C, is a yoke E, the arms a, of which, as shown in Fig. 4:, extend forwardly and then laterally to the sides of the press, and forwardly along the same, and as shown in Figs. 1, 2 and 4, said yoke arms are provided at their forward ends with an aperture extending longitudinally therethrough and through which extends a stem 6, provided at its outer end with a hook c and provided, as shown, with a spring 6 which presses against a suitable projection or head on the end of each arm and against a stop 6*, on the end of the stem and acts to draw said hooks inwardly. Integral with said yoke is a rearward extension 6, which is vertically slotted, as shown, and between the arms of which is connected a link a, the lower end of which is similarly connected in a slot in the rear end of the actuating bed lever I), so that when the toggle bars DD, are flexed in opening the press, the upward movement of the rear end of the lever b, necessitates (because of said link a the downward movement of the outer ends of said arms carrying the inking mechanism over the type thereby.

Extending upwardly upon each side of the press are ways F, which incline rearwardly, the angle, as shown, being approximately 45, although, of course, this may vary, and as shown, said ways at their lower end come in alinement approximately with the outer face of the chase G, and the type set therein, thus projecting beyond the fiat face of the bed for the chase, and are rounded over at. the angle, as shown.

The inking plate or frame, as shown in Figs. 3, 5, and 9, comprises a metallic plate H, having in each end thereof a central gudgeon h, on which is provided a roller h, to track on said ways, and as shown, the inking face of said plate affords a recess milled under at the ends to receive therein a pad comprising a metallic plate If, on which is laid a more or less resilient sheet 721*, of suitable material and over which is stretched a piece of fabric h", similar to type ribbon, adapted to contain ink. Said plate h ,sheet 72. and fabric are engaged together at the ends by means of metallic clamping bars 71?, which are engaged to the plate 7L2, by means of screws or other suitable means and lap over the sheet and fabric. This construction enables the inking pad to he slid out of the carrying frame aifored by the plate H, thus permitting colors of ink to be quickly changed by merely substituting one inking pad for another of different colored ink. A stop It, is provided on the lower edge of the inking frame to prevent the inking pad sliding therefrom during the movement of the inking frame. Said inking plate or frame is carried on the forward end of the yoke arms 6, by means of the hooks 6 which engage the gudgeons h, and as shown, said pad is conveniently provided at diago nally opposite corners with push pins it, the construction of which is clearly shown in Fig. 14:, and which extend through said plate H, and are engaged 011 the top by a spring 71. which acts to force the same outwardly, said pins serving the double purpose of affording a bearing on the ways while the pad is being actuated, and also of affording a bearing on the ends of the chase when inking pressure is applied to the type. Of course, the inking pad alone may he used if desired. Conveniently, however, type ribbon of considerable width is used. For this purpose, as shown, a metallic frame K, is removably engaged upon the back of the inking pad by means of set screws 76, which engage through slots in said frame and in the pad plate, and engaging at the corners of said frame, and projecting longitudinally of the travel of the pad, are brackets 76', notched on the upper side, as shown in dotted lines in Fig. 12, and pivotally engaged to each of said brackets by means of the pivot screw is a spring pressed latch plate is", the spring 70 of which is engaged on said screw and acts to force said latch plate into frictional bearing against the bracket. Said latch plate, as shown, is pro-v vided with a downwardly directed notch corresponding with the upwardly directed notch in the bracket, and is adapted to interfit over the pintle 70 for the ribbon roll and extending upwardly from said latch plate, is a short lever 70", whereby said latch plate may be lifted if first pushed away from the bracket is, to release therefrom the hook k, which, as shown, is integral with the latch plate, and projects slightly beneath the bracket, fitting in a suitable notch therein. As shown, four of said brackets and latch plates are provided to permit the inking ribbon rolls K'K to be journaled on the pad parallel the upper and lower sides thereof. A ratchet wheel 70 -70 is rigidly secured on the shaft or pintle 70 for each of said rollers, and adjacent one of said ways F, and adj ustably secured on said ways, are hooked detents adapted for adjustment to permit one to engage the ratchet 7& of one roll to rotate the same, thus winding the ribbon from the roll is", when the other detent is out of operative position and with reversal to enable the ratchet 73 to be engaged by its detent when the detent for the ratchet 72 is out of operative position, thus reversing the rotation. Numerous forms for said detents may be provided which would serve the purpose. said detents comprise a slotted plate 76 Conveniently, however,

and a slotted plate is, each of which is prothat purpose, and slidably engaging the adjacent ends of each of said plates and engaging also on the guide way by means of a screw 7: is a spring 76 which acts to hold said detents in adjusted position. Set

in said guide way also and extending through L shaped slots in each of said plates, are set screws is, which permit either of said detents to be thrown upwardly into position to engage the corresponding ratchet. As shown also, small guide rolls are provided in alinement with the engaging face of the pad, thus directing the.ribbon over the inking face of the pad and drawing true thereover.

The operation is as follows: hen the pad only is used, the inking rolls may, of course, be removed by releasing the latch 76*, and lifting out the rolls, thus exposing the surface of the pad for printing. The chase with the type therein having been dropped into thepress, as shown in Figs. 7 and 8, the V shaped projection on each end thereof drops into a suitable notch in the sides of the press and acts to position said chase accurately to bring the flat inner face thereof into positive bearing with the chase bed of the machine. l/Vhen upward movement of the lever C, occurs, the movable jaw of the press is thrown down as shown in Fig. 2, while the connecting link 6 in the rear end of the lever b, and the yoke E, forces the yoke arms downwardly carrying the inking pad over the face of the type, as shown in Fig. 2, and to central position, at which point bent levers M, pivotally engaged on the sides of the press engage the rollers on the gudgeons of the pad, and simultaneously engage beneath,the ends of the yoke arms. Further upward pressure of necessity serves to force said yoke arms down more firmly until the inner end of said bent levers engage in stops m, secured on the frame, in consequence, limiting the further downward movement of said arms, but before so engaging said stops, the inclined face of the outer arm of said lever acts to press the pad inwardly by engaging said rollers on the inclined face thereof, thereby forcing the pad upon the type. lVhen the movable jaw is swung downwardly, as shown in Fig. 2, the lever b at its lower end engages upon the bed, thus limiting its further downward. movement, and in consequence the clamping fingers are thrown upwardly to permit the insertion therebeneath of the paper or other material upon which it is desired to print. The weight of the lever 6 together with the weight of the fingers acts to instantly swing said fingers downwardly into engaging position when the jaw begins its upward movement, such upward movement of the jaw being occasioned by a corresponding downward swing of the lever C, which of necessity elevates the yoke arms, thus swinging the pad from between the chase and the paper about to be applied thereon. Of course, in printing in difi'erent colors, should it be desired to employ another colored ink it is only necessary to remove the pad and its ribbon therewith and substitute another in its stead, extra pads with ribbons being provided for additional colors, if desired. In inking, however, the machine may be very rapidly operated, inasmuch as the up ward movement of the lever G, causes the pad carrying the inking rolls thereon to swing downwardlypast the type faces, at which time the ends of the lever M, engage the hooked end of the yoke arms as before described, forcing the pad with its ribbon inwardly to ink the type, after which, with the downward movement of the lever C, the inking mechanism swings upwardly from between the chase and the printing pad. In either the upward or the downward movement of the pad along the ways, the respective rolls for the ribbon are actuated. If the detent on the plate K is thrown upwardly into position to engage the ratchet 70 as the pad is returning to the limits of its upward travel, the upper roll will operate to wind up the ribbon while the lower roll will unwind, the resistance to unwinding being increased by the insertion of any suitable spring resistance 70 inserted between one end of the roller and its bracket. If the detent on the plate 76 is thrown out of operative position and the detent on the plate 7e elevated, the feed of the ribbon occurs as the pad with the ribbon thereon moves downwardly, thus in either event, a positive feed of the ribbon is assured and means are provided for reversing the roll of the ribbon at any time it may be desired. Of course, other means may be employed for forcing the inking means upon the type, as

for instance, referring to Figs. 15 and 16,

the construction may be as before described with reference to the yoke arms 6, but, as shown, a strap of metal 0, is provided on each side of the machine and slotted to receive the yoke arm 6, therethrough, and said strap is also slotted at its rear end to receive the shaft C, therethrough. Said strap engages on the gudgeon H, of the inking pad, as before described, and at its rear end is provided with a. laterally directed projection or stop 0, positioned to be engaged by a cam 0, engaged on the shaft C, closely adjacent said straps, and which act as the lever approaches the upward limit of its upward swing to engage said stops 0, and draw the pads forcibly rearward to press the same upon the type.
