KARL F. KIRKMAN, 013 DELRAY, FLORIDA, ASSIGNOR TO AUTOMATIC PRESS FEEDER COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

PRINTING-PRESS.

Application filed November 14., 1913.

To all whom it may concern Be itknown that I, KARL F. KIRKMAN, a citizen of the United States, residing at Delray, Palm Beach county, Florida, have in- .vented certain new and useful Improvements in Printing-Presses, of which the following is a specification.

My invention relates to printing presses, more particularly those of the. Gordon type and the object thereof is to provide a simple and eilicient inking ribbon mechanism movable over the type bed for the purpose of obtaining an imitation typewriter effect or appearance on the printed sheet.

My invention is capable of being embodied in an attachment which is applicable to the many presses now in use but which, however, may be formed as an integral part of new presses.

The various features of novelty and utility in my invention will be apparent from the description hereinafter given.

In the drawings Figure 1 is a side elevation of a Gordon type of printing press with my attachment applied thereto; Fig. 2 an enlarged side elevation of my attachment showing the type bed and back shaft in section; and Fig. 3 an end elevation of my attachment.

F or the purpose of a clear and definite description of my invention I have shown and will hereinafter describe the same as an attachment to a Gordon press of the conventional type, with the understanding that my invention is not to be limited to any particular type of press except as expressly required by the claims or to an attachment, for it may be built into the machine itself. I will now proceed to describe my invention as it is illustrated for convenience in the accompanying drawings.

As shown, the Gordon press illustrated comprises the usual side frames 1, side frame connecting racket 2, type bed 3, platen 4:, back shaft 5, inking disk 6, inking rolls 7, chase 8 and other parts which, not being directly concerned with my invention need not be referred to.

Describing my invention as embodied in an attachment for a press, such attachment comprises an irregular shaped main frame including vertical side pieces 9 and a cross piece 10 intermediate the length thereof, as shown in Fig. 3. These pieces or arms 9 near their upper ends are grooved at 9 to a semi-circular formation to receive the back Specification of Letters Patent.

shaft 5, such grooved portions having pads 9 for direct contact with the shaft in order to reduce the friction to a minimum. The object of this construction is more particularly to locate or line up the frame with re spect to the back shaft and type bed, and in order to hold the frame in place with relation to this shaft either permanently or temporarily, I employ a pair of vertical bolts 11 extending between projecting portions 12 and a main portion of the frame as clearly indicated in Fig. 2, the bolts lightly and tangentially bearing against the inner side of the back shaft. In practice I prefer to employ other means for securing the frame to the type bed and after this attachment has been obtained the bolts 11 may, if desired, be removed although as will be obvious they may be retained.

As shown more clearly in Fig. 2 the lower portion of the attachment frame has U- shaped openings 18 adapted to receive one of the usual laterally projecting ribs 3 of the type bed. Adjustable clamping screws 14 and 15 screwing into the attachment frame in opposite directions are adapted to bear against the top and bottom faces of said rib with the result that the frame is securely but detachably held to the type bed. These adjusting screws are locked in position by suitable means as the wing nuts 16.

The attachment frame is provided at its upper end with a supplemental frame consisting of two substantially parallel small rods 17 pivoted at their outer ends to the upper ends of the arms 9 and projecting inwardly and over the upper end of the type bed. The inner ends of these rods are bent inwardly toward each other in order to form trunnions for a small horizontal roller 18 supported between them and constituting a roller over which the inking ribbon A passes. This supplemental frame is supported toward its inner end upon the type bed and is adjustably held at a predetermined distance therefrom. The means for this purpose as herein shown consists of sleeves 19 slidable upon the rod 17 and having adjusting screws 20 whose lower ends are adapted to bear against the upper rib 3 of the type bed.

At the upper ends of the arms 9 of the main frame is mounted a roller or supply spool 21 for the inking ribbon A which passes horizontally to the type bed, over the roller 18 thence vertically just in front of the type and then partially around a roller 22 which is mounted between horizontal trunnions 23 adjustable in an extension of the main frame of the attachment. The ribbon then passes over and iswound upon a receiving roller or spool 24 mounted upon a shaft 25 which is journaled in the upper end of a spring-pressed frame which includes two parallel arms 26' secured to a rock shaft 27 having its bearings in the attachment frame. This rock shaft is spring-pressed by means of the spring 28 which is coiled around the shaft with one end fixed and the other selatter roller is positively actuated by the following driving connections which are simple and efficient for the object in view.

Fixed to the roller 22 is a pinion 30 which meshes with a driving gear 31 secured to a horizontal shaft 32 journaled to one side of the attachment frame. A curved rock arm 33 is loosely mounted on this shaft 32 and provided with a pivoted pawl 34 which is adapted to cooperate with a ratchet 35 secured to the shaft 32 with the result that when the arm 33 is rocked the ratchet drive will be operated and the shaft 32 rotated and the roller 22 thereby rotated by the gear wheel 31 and pinion 30. This rock arm 33 is movable against the tension of a spring 36 coiled around a rod 37 whose lower end is secured to the rock arm by a transverse pin 38. This spring bears at its lower end against the rock arm and at its upper end against a rib 39 on the main frame, through which rib the rod 37 passes and by whlch it is guided. This rock arm is positively actuated at every movement of the press by contact with a fixed part of the press.

In thepresent instance I attach to the usual side frame connecting bracket 2 a supplemental bracket 40 clamped thereto by means of the set screw 41. This bracket 40 has a laterally projecting rod portion 42 po-,

lower end or foot 33" of the rock arm. When the type bed and all its associated parts are rocked in the operation of the press this foot 33 will come into contact with the rod 42 with the result that'the arm 33 will be rocked with respect to the shaft 32 and its ratchet wheel. The pawl 34 will thereupon engage new teeth on the ratchet wheel and when the type bed moves in the other direction the spring 36 will rock the arm 33 in the opposite direction, thereby driving the ratchet wheel and in turn driving the roller 22. As a result the inking ribbon A will be fed a predetermined distance at each operation of the press, the ribbon unwinding from the reel or spool 21 and winding upon. the

receiving spool 24. When it is desired to rewind the ribbon back upon the spool 21 the pawl is raised from its engagement with the ratchet wheel and the projecting spring wire or rod 43 is sprung over the pin 38 so that it is held in its inoperative position. This wire or rod 43 serves not only this particular purpose but also affords additional weight to the pawl which is of the gravity type. The spool or reel 21 is now turned backward by the operator by means of the crank'44. It will be understood that the inking rollers 7 operate in the usual way, taking ink from the disks 6 and applying it to the ribbon A instead of the type direct.
