When this figure, 1 designates the framing of the makey 28 is moved from its normal position, it chine, and 2 indicates the segment'in which causes the cam-like projection 27 to be forced into the recess 26 in the plate 20, thereby causing said plate to be forced against the tension of its spring 21 to move the plate 20, the yoke 23, and imprint-roller-carrying arm 25 in a vertical direction for purposes which will hereinafter more fully appear. This imprint-roller-carrying arm may be constructed of a single piece; but I prefer to construct it of a plurality of sections, as clearly indicated in Figs. 5 and 6 of the drawings. In these figures it will be observed that the arm proper, 25, terminates at a hinged joint 31, at which point a link 32 is pivotally connected to the arm proper, 25. The rod 33, which constitutes the pivot that unites the arm proper, 25, to the link 32, is provided with a finger-piece or button 34 and is rigidly secured to the link 32, as indicated, by the pins 35. The link 32 in turn is pivoted or hinged tea carryingpiece 36, as indicated at 37. This carryingpiece 36 is provided with a slotted portion 38, into the slot of which extends a pin 39, that projects from an arm 40, secured to the arm proper, 25. The carrying-piece 36 has loosely pivoted thereto an imprint-roller 41, which may be readily removed by a withdrawal of the screw-pivot 42. This imprint-roller 41 is provided with a peripheral imprint-surface 43, which is of the same character throughout its extent. In Fig. 5 it will be observed that this peripheral printing-surface is adapted to print a solid line, whereas the roller shown in Fig. 7 of the drawings is adapted to print a series of dots. It is obvious that any suitable printing-surface, such as a series of stars and the like, may be provided upon the imprint-roller. When the operator desires to change the character of the imprint-roller, it is merely necessary to remove the pivotal screw 42 and substitute an imprint-roller having the desired imprint-surface. Pivoted to the carrier 36, adjacent to the imprintroller, is an inking-roller 44. The periphery of this inking-roller is adapted to contact with the periphery of the imprint-roller in order to ink the imprint-surface thereof and to rotate the imprint-roller by frictional contact. Thus I prefer to form the inking-roller with a groove 45, that is adapted to receive the printingsurface of the imprint-roller and at the same time permits the other peripheral surfaces of the inking-roller to contact with the general periphery of the imprint-roller, as indicated in Figs. 2 and 6 of the drawings.

The pivot 33, which unites the arm 25 and the link 32, is provided with a locking device for maintaining the carrier 36 in the position to which it is moved by the hand-operated button 34. In the present instance these locking means consist of a disk 46, that is provided with notches 47. A s iring-prcssed pawl 48 is pivoted to the arm 40, and the nose 49 of this pawl is adapted to be forced into either of the notches 47 in the disk to maintain the carrier and the imprint-roller carried thereby in either of the positions represented in full and in dotted lines in Fig. 5 of the drawings for purposes which will hereinafter more clearly appear.

A bracket 50 is secured to the framing of the machine, and it is on this bracket that the pivot 29 of the key 28 is supported. This pivot 29 likewise constitutes the pivot for a second key 51, which, like the key 28, is provided with a finger-piece 52 at its outer end. The inner end of the key 51 is connected to a link 53, which in turn is connected to a bellcrank lever 54, that is pivoted to the bracket 50, as indicated at 55. The opposite end of this bell-crank lever is connected to a short link 56, that in turn is united to an arm 57, that projects from the pivot 24 of the arm 25. It will thus be seen that the portion 58 constitutes in a sense a rock-shaft that is provided with two arms one the arm 25 and the other the arm 57. By moving the key 51 from the full-line to the dotted-line position indicated in Fig. 3 of the drawings the socalled rock-shaft 58 will be turned on its axis, and the imprint-roller 41 will be conveyed to the printing position above the typebar guide 13, as indicated in dotted lines in Fig. 3 of the drawings. When the key is re leased, the parts will be restored to their normal or full-line position by a spring 58 which spring is connected at one end to a pin projecting from the bracket 50 and at the other end to the arm 25. When the imprint-roller is set in the manner indicated in full lines in Fig. 5 and the key 51 is moved to the dottedline position indicated in Fig. 3 of the drawings, the imprint-roller will be brought to such position that the imprint-surface thereof will rule a straight line on the paper by moving the carriage and platen along the machine. If it is desired to rule or to cause an ornamental line to be imprinted in a direction parallel to the sides of the paper, it is merely necessary to turn the button 34, thereby causing the imprint-roller to be moved to the dotted-line position indicated in Fig. 5 of the drawings, and a movement of the key 51 will cause the imprint-roller to be brought to the printing position. A rotation of the platen around its axis at this time will cause an imprint to be made parallel to the sides of the paper.

From an examination of Figs. 2, 3, and 8 of the drawings it will be observed that the key 28 is provided with a right-angled projection or lug 59. This lug 59 extends into the path of the key 51, so that a movement of the key 28 from the full-line to the dotted-line position in Fig. 3 will cause the key 51 to be moved with it. This movement of the key 28 brings about a vertical downward movement of the plate 20 by reason of the cam 27 on said key contacting with the apertured portion 26 of said plate 20. This movement of the plate 20 will cause the arm 25 and the parts carried thereby to be lowered, so that the imprintroller will assume a different position when it is forced to the dotted-line position indicated in Fig. 3. This movement of the plate 20, which constitutes a support for the imprint-roller, is for the purpose of providing double-line ruling or double ornamental lines. Thus, for instance, for double underscoring it is merely necessary to first move the key 51, when the imprint-roller will be conveyed to the printing position, and the carriage may be moved longitudinally to cause a line or imprint to be made. After this line is completed the key 28 is moved to shift .the printing position of the imprint-roller and to simultaneously convey the imprint-roller to the printing position by reason of the lug 59 on the key 28 contacting with the key 51, thereby causing the key 51 to move with the key 28. Thus the shifting operation to vary the imprint position of the roller and the movement of the roller from the normal to the printing position is accomplished by a single movement of the key 28.

Fixed upon an arm 60, which may constitute a portion of the yoke 23, is a segmental inking-pad 61. The are of this segmental pad is drawn from the pivotal center of the arm 25, so that the inking-roller 44 will contact with the pad 61 in the movement of the former with the imprint-roller to and from the printing position. This contact with the segmental pad causes the inking-pad to be rotated during its movement toward the printing position, and the rotary motion thus imparted to the inking pad is transmitted to the imprint-roller, so that its entire printing-surface will be inked during its movement to and from the printing position, so that when it attains the printing position the entire printing-surface will be inked. It will be seen that the contact of the peripheral printing-surface of the imprint-roller upon the paper will cause the same to be rotatedto bring a newly-inked surface into contact with the paper as the paper progresses and that this rotary movement thus imparted to the imprint-roller will cause the inking-roller 44 to be rotated, thus automatically and constantly inking the imprint-surface of the roller 41.

From the foregoing it will be observed that the inking-roller 44 partakes of the bodily movement of the imprint-roller to or from operative or printing position and likewise imparts a rotary movement to theimprint-roller. In the act of printing the imprint-roller imparts a rotary movement to the in king-roller.

I prefer to have the imprint-roller operate directly upon the paper and to automatically ink the imprint-surface of said roller, for the reason that a clearer line or imprint may be made and inks of different colors from those used on the machine may be employed. Nevertheless it is obvious that the so-called imprint-roller may be arranged tocontac't with.

the ribbon l4 and that the lines or other characters imprinted upon the surface of the paper may be accomplished through the contact of the imprint-roller with the ribbon.

It will be observed that by my invention I have provided a simple and efficient device derstood that various changes may be made in the construction without departing from the spirit of my invention.
