Original application filed April 13,1927, Serial No. 183,318,

Divided and 1 1; application 1115a This is a division of original application filed by me April 13,1927, Serial No. 183,318. 7 This invention'relates to improvements in printing and stamping machines, andhas 5 particular reference to such devicesxwhich are adapted for endorsing, cancelling, or otherwise printing upon bank checks, tickets, letters, and similar articles.

The subject matter of this invention is dis- 7 10 closed in my co-pending-l application "for Printing and stamping machines, filed April 13, 1927, Serial No.*183,318 but is not claimed therein,'the present application being a division of the said application Serial'N0.'183,318.

In the above identified co-pendingapplication, the invention hasbeen embodied 1n a machine which is power-driven and'capable of expeditiously operating upon a quantity of successively fed paper sheets on like articles as theyare passed through a'printing couple. This printing couple comprises an impression roller and a printing roller rotating in opposition to each other, andthe prmcipal object of this inventioniis to provide a.

novelinking'mechanism for supplying ink to the printing roller. A supply of ink is main- 7 tainedin an ink well which is mounted on a pair of swinging armsandprovided with an ink roller and a wiping r0ller.- The arms which support the'ink well are eccentrically pivoted to another' pair. of arms, which in turn are pivoted to the mainframe 'orbase ily understood from the following 'descrip tion in connection with the accompanying drawings, wherein one form of the invention has been shown by way of illustration, and wherein V 1 Fig. 1 is a top plan view of the improved printing machine; and

T The invention has been shown as embodied in amachine for endorsingbank checks,and in" the followin description, when bank checks are spe'ci ed in connection with the operation of thedevice, it is to be understood that their equivalents may be operated upon in the same way. Thedevice comprises a substantially fiat base PlELtGA rhGIG' shown as C9 of rectangular outline and preferably having a plurality of cushion feet whereby to be supported upon a desk, table, or the like 'without likelihood of damaging thesurfacethereof.

Securedto the base plate A intermediate its ends is a supporting-bracket A having a pair of upwardly extending spaced arms A and A said arms being'disposed adjacent the-opposite side edges of the base plate. Adjacent their'upper ends, the arms A and (a A are provided withbearing bosses having axially alined openings in which are secured stationary mounting shaftspthe inner ends of which are spaced from each other to rotat ably supporta novel printing roller B of the "is printing couple.

rotation above the printing roller B, and power is supplied by an electric motor C to xrotate the said printingiand impression rollers through suitable gearingl and clutch mechanism, not shown, and successive rotations of the printingroller are controlled by j the tripping mechanism D as it is acted upon bythe'successively fed checks.

An impression roller B? is journaled for go ends of the arms F as well as the ink well F are normally urged upwardly toward the printing roller B. Rotatable within the ink well F and partially below the surface of the ink is a roller F which has surface contact with a distributing roller F, of felt or similar material, said distributing roller in turn having surface contact with the printing roller B. The distributing roller F is provided at its ends with trunnions F which are received in downwardly inclined slots F ,in the upper ends of the swinging arms F and said arms F are provided adjacent their lower ends With projections F adapted to abut againstadjusting screws F to limit the movements ofsaid arms toward the roller B. A wiping roller F is also rotatably associated with the ink roller F it having trunnions F received in slots F in the end walls of the ink well F and said wiping roller engages the surface of the ink roller to relieve the same of superfluous ink before it rolls against the intermediate distributing roller F Thus a uniform amount of ink will at all times be applied to the die as the printing roller rotates, and there will be no feeding or distributing of ink when the printing roller is not rotating. To compensate for wear of the various parts, the adjusting screws F may be turned either in or out to determine the desired limit for the roller F Integral with the base A and forwardly of the ink well, is a slotted lug F" in which is pivoted at F a latch F said latch having a hook portion F adj acentits upper end for engagement with the upper edge of the ink well F A compression spring F normally forces said hook portion F toward the ink well, and when it is desired to temporarily discontinue the ink supply, (for example, when the roller F has become saturated), the ink well is pressed downwardly about the pins F to the position indicated by dotted lines in Fig. 5, in which position the latch holds it. In this condition, the printing roller B will continue tobe inked by the distributing roller F due' to the action of the springs F on the arms F indirectly through the ink well arms F From the foregoing it will be clear that a novel inking mechanism has been provided for printing machines of this character, whereby the printing roller will be supplied with ink uniformly during the operation of the machine; The construction is'extremely simple, capable of being economically produced, and the parts are easily accessible for inspection, adjustment or cleaning when necessary. Obviously the invention is susceptible of modification in the details'of consignature hereto.

struction, and arrangement of parts, and the right is herein reserved to make such changes as fall within the scope of the appended claims without departing from the spirit of the invention.

Having thus described my invention, what I claim is:

1. In a printing machine of the class described, the combination with a printing couple, of inking means including an ink well, an ink roller associated therewith, an ink distributing roller mutually engaging said ink roller and the printing member of the printing couple, swinging arms supporting the distributing roller for movement toward and away from the printing element, and an eccentric pivotal connection between said arms and the ink well.

2. In a printing machine of the class'described, the combination with a printing couple, of inking means including an ink well, an ink roller associated therewith, an ink distributing roller mutually engaging said ink roller and the printing member of the printing couple, swinging arms supporting the distributing roller for movement toward and away from the printing element, and an eccentric pivotal connection between said arms and the ink well.

3. In a printing machine of the class described, the combination with a printing couple, of inking means including an ink well, an ink roller associated therewith, an ink distributing roller mutually engaging said ink roller and the printing member-of the and the ink well, a latch for engaging'the ink well to hold the ink roller, and means acting through the ink well support for maintaining the distributing roller in operative position with reference to the printing couple when the latch isin engagement with the ink well.

In testimony whereof, I have afiiXed my RAYMOND F. JAHN.
