ROLL-PAPER-PRINTING ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 778,813, dated December 27, 1904.

Application filed March 14,1904- Serial No. 197,995.

1'!) no whom it nan/y concern:

Be it known that I, FRANK L. TAYLOR, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Roll-Paper-Printing Attachments, of which the following is a specification.

My invention relates to improvements in printing attachments for roll-paper holders whereby an advertisement or other matter may be printed on the strip as it is pulled from the roll. Its object is to provide a compact simple adjustable device of this character and which may be readily made to print or not, as desired.

It consists of the parts and the construction and combination of parts, as hereinafter more fully described, having reference to the accompanying drawings, in which- Figure 1 is a side view of my device with the casing in section. Fig. 2 is a plan view of same with casing in section.

A represents a suitable frame or rack carrying the paper-roll 2 and having the usual knife 3, by which the strip is severed after a desired length has been drawn off.

My attachment comprises a pair of separated angular arms A, between which the respective printing, inking, and distributing rollers 5 6 7 are supported. These arms have one portion pivotally hung upon a cross-rod 8, journaled in the clamps 9, by which the device is secured to the top bar of the frame A. Their other portion is bent upwardly to include an angle, preferably less than ninety degrees. The arms are slotted at their angles, as at 10, to receive the journal-pins of the printing-roller 5. The upwardly-projecting portions of the arms are each provided with an inwardly-projecting part 11 in the same plane with the rest of the arm. The two arms are rigidly connected above the rollers by the bar 12. The projections 11 are longitudinally slotted, as at 13, to aiford adjustable bearings for the journal-pins of the inking-roller 6, which is arranged to bear always against the distributing-roller 7. The latter is in the path of the printingsurface 14 on roller 5, so that at each revolution of the latter a suitable distribution of ink on the typeface will result. The inkingroller is made always to bear against the distributing-roller by means of the set-screws 15 and the springpressed followers 16. By tightening or loosening screws 15 the tension between the rollers is varied, and the amount of ink delivered to the printing-roller is regulated. The slots 10 lie substantially in a radial plane to the paperroll when the printingroller is in Working position to allow the latter more readily to accommodate itself to the paper-roll. By employing supporting means for the several rollers, as shownto wit, the rigid one-piece angular armsthe Whole apparatus is confined within a very small compass and there is nothing to project beyond the printingroller, and the latter may not even extend beyond the paper-roll. A spring 17, surrounding rod 8 and having its central portion engaging the top bar of frame A and its ends embracing the arms, acts upon the arms to press the printing-roller normally against the paper-roll to give the required impression as the paper is drawn forth. In case a blank strip of indefinite length is to be drawn off the roll the printing attachment may be temporarily thrown out of service by lifting up on the arms to allow the pins 18, carried by the clamps 9, to be slipped under the arms and support them against gravity and the force of spring 17. By withdrawing the pins 18 the printing-roller is allowed to contact with the paper-roll and print the sheet as it is unwound.

The various parts may be inclosed in a suitable triangular casing, as 19, open on one side to allow it to slip readily over the arms and rollers and having a downwardly-projecting lip or portion 20 adjacent to one edge to engage behind rod 8 and intermediate of the coiled parts of spring 17 Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A paper-printingattachmentcomprising clamps to attach it to a rack, spring-pressed arms pivotally connected with said clamps each of said arms bent intermediate of its ends and having a projecting part reentering the angle included by the bend of the arm, a printingroller, inking-roller and distributing-roller journaled in said arms, and means by Which the arms are supported against the tension of their spring to retain the said printing-roller out of engagement with the paper-roll.

2. A roll-paper-printing attachment comprising clamps to attach it to a rack, springactuated arms pivotally connected with said clamps, said arms bent intermediate 01 their ends and each having a projecting portion reentering the angle included by the bend of its respective arm, printing, inking and distributing rollers supported by said arms, said inking-roll mounted in said reentering por tion of the arms, and means by which the arms are supported against the tension of their spring-actuating means to retain the printingrollcr out of engagement with the paper-roll, said supporting means including stops carried by the clamps.

3. A roll-paper-printing attachment comprising clamp members, arms pivotally connected therewith, said arms each being bent intermediate of their ends and having a projecting part reenter-ing the angle included by so bending the arm, a printing-roller journaled in said arms proximate to the angles thereof, an inking-roller supported on said reentrant portions of said arms and a distributing-roller associated with said inking-roller.

i. A roll-paper-printing attachment comprising clamp members, spring-pressed arms pivotally connected therewith, said arms each being bent intermediate of their ends and having a projecting part reenter-ing the angle included by so bending the arm, a printing roller journaled in said arms proximate to the angles thereof, an inking-roller supported on said reentrant portions of said arms and a distributing-roller associated with said inking-roller,

and means carried by the clamps to hold the arms against the force of their springs.

5. A roll-paper-printing attachment comprising the combination with a paper-roll and rack therefor, of clamp members engaging said rack, a rod connecting said clamp members, arms pivoted to said rod, a printing-roller journaled intermediate of the ends of said arms, springs engaging the rack and arms to press the printing-roller normally against the paper-roll, said arms being bent intermediate of their ends and each having a projecting portion reentering the angle included by the bend of its respective arm, an inking-roller yieldingly mounted in said projecting portions,and adistributing-roller carried between the free end of the arms and contacting with the printing-roll.

6. A roll-paper-printing attachment com-' prising the combination with a paper-roll and rack therefor, of clamp members engaging said rack, a rod connecting said clamp members, arms pivoted to said rod, said arms being bent intermediate of their ends and each having a portion projecting into the angle included by the bend of its respective arm, a printingroller journaled in the angular portions of said arms, springs engaging the rack and arms to press the printing-roller normally against the paper-roll, means connecting the arms, inking and distributing rollers carried respectively by the reentering portion and one of the main parts of the bent arms, and a removable casing for said rollers and arms, said casing having a downwardly-projecting part to engage behind the connecting clamp-rod.

In testimony whereof I have hereui'ito set my hand in presence of two subscribing witnesses.

FRANK L. TAYLOR.
