COMBINED HAND AND AUTOMATIC ROLL PRINTING DEVVIQE.

SPECIFICATION formingpart of Letters Patent N 0. 747,325, dated December 15, 1903. Application filed March 15, 1901. Renewed September 14, 1903. $erial No. 173,175. (No model-) To all whom it may concern:

Be it known that I, CHARLES P. KING, acitizen of the United States, residing at Cincinnati, Hamilton county, State of Ohio, have invented a certain new and useful Combined Hand and Automatic Roll Printing Device; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, attention being called to the accompanying drawings, with the reference-numerals marked thereon, which form also a part of this specification.

This invention relates to printing devices of the kind where a printing-roller, together with an inking-roller, is mounted in aframe, the printing being done while the former is in contact with the paper and while one moves past the other, which movement rotates the printing-roller by reason of frictional contact between the two. The rotation of the printing-roller causes also rotation of the inkingroller, whereby this latter supplies ink to the former.

The features of the invention relate to a construction which permits this printing device to be used in two ways,one being by hand, when a hold is taken of the frame supporting the roller and the device ismoved over the paper, the printing-roller being rotated by its frictional contact with the paper while so moving over it.- The other way is a use in connection with paper in roll form, the de-' vice being then attached close to the paperroll and in a manner to maintain contact with the paper as the roll is reduced, the printing being done automatically whenever the paper-roll rotates in consequence of paper being drawn off therefrom.

In the following specification, and particularly pointed outin the claims at the end thereof, is found a full description of the invention, together with its manner of use, parts, and construction, which latter is also illustrated in the accompanying drawings, in which Figure 1 showsin aside view my device used in connection with a roll of paper, which may be wrapping-paper, and receives printed matteradvertisements, for instanc ewhenever from which they project at right angles.

paper is drawn off from the roll. Fig. 2in a similar view shows my device detached and ready for use by hand. Fig.3 is'a top view of Fig. 1 with the dust-proof cover removed, and Fig. 4 shows a front view of the intermediate or supporting member of the device.

The numeral 10'indicates a roll of suitable paper, which may be wrapping-paper, and is supported in the usual manner between the uprights 11 of a suitable frame, of which 12 is the base and 13 the top. A knife or tearing-blade 14 is yieldingly connected to this latter byarms 15 and serves"as a means to separate from the roll such paper as has been drawn ofi therefrom.

16 is the printing-roller, provided on its face with type matter of any suitable kind and mounted for rotation bet ween the arms 17 of a frame 18. This latter is supported in a manner to be presently explained, the support being such that the printing-roller is constantly held in contact with the paper and follows the same as the roll diminishes in diameter. It is caused to rotate by reason of this contact whenever the roll rotates in consequence of paper being drawn oif therefrom and which rotation with the face of the roller in contact with the paper causes this latter drawing off or unwinding of the paper from the roll. 19 is the roller which supplies the ink to the printing-roller, it being mounted between arms 21, forming parts of frame 18, The journals 22 of this roller occupy slots 23 in said arms, and they have attached to them springs 24, c0nnected with their other ends in a manner to hold the inking-roller in contact with the printing-roller. These springs may be coil-springs or rubber bands,as shown.

The inking-roller may receive its supply in any manner. It may be simply covered with a pad 25, which is kept saturated with ink. From frame 18 there projects a handle-shaped shank 26, which when in a position as shown in Fig. 2 may be taken hold of for moving the roller over the paper, the whole thus serving as a hand printing device. The printingroller is thus caused to rotate by reason of its contact with the paper while being moved thereover. This shank is provided with means permitting its ready attachment to the free end of a spring 27, secured to the frame supporting the paper-roll, and which free end hasa tendency to approach the former, so that the printing-roller is caused to lie against the paper and maintain contact therewith. In this particular connection the device serves now as a roll-printing device and operates in the manner before explained.

Spring 27 is so shaped as to form a loop between two parallel branches, the ends of which branches are formed into coils each wound around a boss 28, projecting laterally one from each side of a bracket 29, which is attached to the frame supporting the paperrolll This attachment may be of any kind, permanent or so as to permit detachment, in which latter case a screw-clamp 31 is provided in connection therewith, whereby bracket 29 is attached to top 13 of the paper-supporting frame.

The winding of the above-mentioned coils of the spring around bosses 28 and the connection thereto of their outer ends may be readily seen in the drawings and is such that the free end of the spring has a constant tendency to approach the paper-roll. The attachment of the printing device to the spring is by handle 26 of the former and is at two points thereof. At one point it is by a hook 32, which engages the lowermost or extreme outer part of the free end of the spring, hooking into the loop formed thereat. At the other point it is by a projection 33, which rests loosely in a notch 34 of a brace 35. This brace must be capable to move with and follow the spring, for which purpose it is accordingly formed or connected. The connection at this latter pointthat is, by projection 33-is merely a support, the object being to hold the printing-roller with sufficient pressure against the paper to obtain a good impression, which the mere support by hook 32 would not accomplish. The entire support and connection of the printing device is positive only as far as its enforced contact with and movement toward the paper is concerned; but otherwise it is sufliciently loose and free, by reason of the limited support at two points only located in a central line, to permit the roller to vibrateor Wabble in a longitudinal direction, so as to adjust itself to any inequalities in the thickness of the paper-roll.

In order to hold the free end of the spring positively in a central position and against any lateral movement, I provide swinging braces 36, engaging spring 27 laterally and confining it between them to its central position. These braces are pivotally connected to bearings 37, formed at the outer ends of bosses 28, which are preferably turned off thereat. As will be seen, while these braces are unable to yield laterally, and therefore hold the spring to its central position, they are free to move with this latter to or from the paper, thus preventing interference with the function of the spring to hold the printing device in contact with the paper-roll.

Where it is desired to use the device for printing by hand, as shown in Fig. 2, it is only necessary to lift it off from spring 27.

38 is simply a cover to keep the dust ofi of the ink-roller and is omitted in Fig. 3.

Having described my invention, I claim as new- 1. In a printing device, the combination of a printing-roller, an inking-roller, a frame on which both are mounted, a spring adapted to be attached to the supporting-frame of a paper-roll and having a free end with a normal tendency to approach this paper, a brace 35 on this spring having a central notch, a shank projecting from the frame of the printing device, a projection 33 thereon adapted to occupy the notch in brace 35 and a hook 32 adapted to engage the free end of the spring.

2. In a printing device, the combination of a printing-roller, an inking-roller, a frame on which both are mounted, a bracket adapted to be attached to the supporting-frame of a paper-roll and having bosses 28 projecting laterally in opposite directions, a spring 27 shaped to form a loop at its free end and having its other ends each connected to one of the bosses mentioned, the connection being such that said free end has a normal tendency to approach the paper-roll, swinging braces 36 one on each side of the spring to confine the movement 0! the latter in a manner to hold it centrally in position and a shank projecting from the frame of the printing device and adapted to be detaehably connected to the free end of the spring.

3. In a printing device, the combination of a printing-roller, an inking-roller, a frame on which both are mounted, a spring adapted to be attached to the supporting-frame of a paper-roll, and having a free end with a normal tendency to approach this paper, means whereby the frame of the printing device is connected to the free end of the spring, and swinging braces engaging the free end of the spring at each side to prevent displacement of the same laterally and confine it centrally in position.

In testimony whereof I hereunto set my hand in the presence of two witnesses.

CHARLES P. KING.
