INK-RIBBON MECHANISM.

SPECIFICATION forming part of Letters Patent No. 655,985, dated August 14, 1900. Application filed September 11, 1899. Serial No. 730,063\ (No model.)

erence being had to the accompanying drawings.

My invention relates to mechanism whereby an ink-ribbon may be detachably secured and automatically shifted in cooperative relation with a printing-press of ordinary construction.

My invention comprises simple and efficient ribbon-shifting mechanism and means whereby a signal may be automatically given by said mechanism when it becomes necessary to reverse thedirection of traverse of the ribbon.

My invention also comprehends certain adj unctive devices arranged to facilitate the insertion and removal of the ink-ribbon with respect to said shifting mechanism, as hereinafter described.

In the accompanying drawings, Figure 1 is a sectional view of a printing-press, showing a convenient embodiment of myinvention applied thereto. Fig. 2 is' an enlarged sectional view of certain parts shown in Fig. 1. Fig. 3 is a longitudinal sectional view of one of the feed-rollers, showing an automatic sig naling device in connection therewith. Figs. 4. and 5 show details of construction of the feed rollers, &c. Fig. 6 is a fragmentary sectional view showing the arrangement of the parts for manual operation of the inkribbon rollers. Fig. 7 is a view of the socket end of the roller shown in Fig. 6. Fig. Sis a sectional elevation of the auxiliary ribbon roller or spindle.

Referring to Fig. 1, A is the main frame of an ordinary printing press, in which is mounted the driving-shaft B, provided with the band-wheel b and pinion b, the latter gearing with the cam-wheel O and serving to rotate it. The eccentric stud 0 upon said wheel 0 is operativelyconnected by the link 0 with the stud 6 upon the bed E to rock said bed upon e in the frame A. The chase E, containing the form of type E is secured upon the bed E, and the platen D is given the proper movement by the rock-arm D,

whose roller d is engaged in the cam-groove c of said wheel 0.

The to-and-fro motion of the bed E, imparted to itby the link 0'', &c., is transformed into oscillatory motion of the roller-frame F,

concentric with said stud c, said frame F being pivot-ally connected at f with the rollerarm G, whose opposite extremity is pivoted at 9 upon the fixed frame A. The ordinary inking-disk H is mounted upon the bracket h, secured upon the bed E and intermittently rotated by the pawl-lever I, pivoted at h on said bracket, said lever being rocked by the engagement of its roller 1 with the upper face of the frame'F.

The above-described members of an ordinary printing press form no part of but serve to actuate and cooperate with my improved mechanism, comprising the ribbonfeed rollers J and K, arranged upon the bed E, respectively above and below the chase E, to shift the ribbon L across the face of the type E said rollers being respectively rotated in alternation step by step by the pawl-levers j and 7a, which are respectively connected by the links J K with the ordinary disk-lever I, above described. It is to be understood, however, that my-d'evice may be actuated by suitable connection with any other movable member of the press. The parts are so arranged that the desired oscillatory movement is imparted from said lever I to both of the pawl-levers j and 76, so that the ink-ribbon L may be wound upon either of said rollers, while the other rotates idly, the respective pawling devices being alternately engaged and disengaged, according to the desired direction of traverse of the ribbon L. I shall only describe in detail the roller J and the parts connected therewith, it being understood, however, that the de vices connected with the roller K are substantially counterpart thereto and correspondingly lettered on the drawings.

Referring to Figs. 3, 4., and 5, the ribbonfeed roller J is mounted in the brackets e and e for rotation upon the-fixed cone-bear ings J and J The pawl-leverjis fixed upon the pawl-disk j, which is loosely mounted upon the shankj of the bearing J 3 and carries the pawl j*, in position to engage the ratcliet-wheelj, which is also loosely mounted upon said shank. The lugj on the wheel J is adapted for engagement in the slot j of the bearing-platef on the roller J. The bearingstudj at the opposite extremity of said roller J is mounted to telescope therein, but is normally maintained in its extended position by means of the springj being so arranged that the stud j may be thrust inward to release the roller J from its bearings for removal. As shown in Fig. 2, said rollers J and K are provided with hook-pins j 10 to positively engage the ends of the ink-ribbon L, which is extended from the roller J to the roller K over the face of the type E in the chase E and depends over the guide-rod E upon which are secured adjustable spring-clips e which serve to guide and prevent its lateral displacement.

The arrangement of the parts above described is suchthat both of the pawl-levers jand k are operated by the lever I, &c., at each stroke of the bed E, and it being necessary to render one or the other of the pawls 7' and k inoperative in accordance with the direction of the traverse of the ribbon L both of said pawls 7' k are arranged to be manually rotated upon their respective axes on the pawl-disks to the disengaged position indicated atj in Fig. 2. In order that the operator may be warned when it is necessary to reverse the position of said pawls, I find it convenient to provide a signaling device, which is automatically operated," as follows: The roller J is conveniently made of wood or other non-conducting material, bored at J to receive the wiring connections for the switch J The bearing memherj being arranged to telescope within the metal sleeve 7' inclosing the springj, said sleeve is electriean electric circuit is established between the bearings J and J and whenever the ribbon Lis wound upon the roller the push-piece thrusts the spring 7' away from said bushing and the circuit is broken. The brackets e and 6 being both secured upon the metallic bed E the bearing J is insulated from its bracket 6 as indicated atj, in order to conveniently establish an exterior circuit from the bearing J to the bearing J Said circuit comprises the wiring connections at n, the bell or other signal M, the battery N, and the switch 0.

Although I have diagrammatically shown the electric connections as applied only to the roller J, it is to be understood that both of the rollers J and K may be in electrical connection with the bell M, so that when the ink-ribbon L has traversed the face of the type E in either direction to the limit of its length the unwinding of said ribbon from one or the other of said rollers permits the respective switch J or K to project, as indicated at J in Fig. 2, and thus the signal is operated automatically whenever it is necessary to reverse the pawlsj It is of course necessary to change the ribbon whenever a different color of ink is desired, and even if the press is operated continuously with a singlecolor of ink it is necessary at intervals to renew the ribbon in connection with the rollers J and K, so that although said rollers are provided with means to permit of their removal from the press, as above described, I find it convenient to provide means to conveniently wind-and unwind an ink-ribbon with respect to said rollers without removing them, as follows: As shown in Fig. 6, the bearing memberj of the roller J is adapted to be rotatively engaged by the cranlehandle J the squared extremity of which is arranged to be entered in the similarlyshaped socket J in said member j through the bearing J 7 in the bracket 6 In this form of my invention said bracket may be convenientlyinsulated, as indicated atj. Said handle J may be inserted and withdrawn at the will of the operator without disturbin g the normal relation of the ribbon-feed rollers and the parts connected therewith.

As a temporary support for the roll of ribbon I provide an auxiliary roller or spindle P, which, as shown in Fig. 8, may be detachably mounted in the bearings 9 secured upon the bracket 7t of the press. Said spindle P is provided with a crank-handle I and is retained in proper position in the press by the engagement of its grooved collar 17 with the bearing 1), the latter being open at the top to facilitate the insertion and removal of the spindle. The spring P is fixed at its extremity p in the recess 19 in the spindle P intermediate of its length, and the free extremity p of said spring is pointed for engagement with the ink-ribbon which is to be wound thereon. Although said spring P suliices to prevent accidental displacement of the ink-ribbon, it is so proportioned as to permit of the removal of the roll of ribbon from said spindle in the direct-ion of the arrow upon Fig. 8.

It being desired to remove or replace the ribbon with respect to the rollers J and K, an empty spindle P is inserted in the bearings p p, and the ribbon L in the press having been wound upon one of said rollers J or K to the limit of its length its extremity is detached from the hook-pinsj or 70 and engaged with the point f of the spring P of the spindle I and the latter rotated until said ribbon is wound upon said spindle P and unwound from the said feed-roller to the limit of its length, whereupon its extremity being detached from the hook-pins of the feed-roller and being completely wound upon said spindle the latter is lifted from the bearing 9 and withdrawn from the bearing 19.

The ribbon which is to replace the inkribbon withdrawn as aforesaid being similarly mounted upon a spindle P, said spindle is inserted in the bearing 19 and its collar 10 engaged with the bearing 19, and the free extremity of said ribbon being engaged with one of the feed-rollers the handle J is inserted in the latter, as shown in Fig-6 and above described,and said ribbon is wound upon said roller by manual rotation of said handle, while the spindle P idly rotates in the bearings 19 p. The inner extremity of the rolled ribbon thus unwound from the spindle P being extended over the type-form E in the normal position shown in Fig. 2 and engaged upon the other of said feed-rollers, the automatic operation of the parts above described may be resumed.

It is to be understood that themechanism hereinbefore described may be applied to any ordinary form of printing-press, and therefore I do not desire to limit myself to the precise construction andarrangement of the parts which I have illustrated, as it is obvious that various modifications may be made therein without departing from the spirit of my invention in accordance with the construction of the press in which said mechanism is to be embodied.
