To all whom it may concern Be it known that l, lim'ssi-zs G. LEE, citizen of the lnited Staten, residing at Brooklyn, New York, have inventedcertain new and h lt ill Improvements in inking-Ribbon Mechanism for .-.(l(lres 1ing'-Machines, of which the following is a specification.

My present invention is a division of that disclosed in application for Letters Patent of the United States; filed by me .etugusat lo, 100%, No. 313044, and consists in the features and combination.of parts relating; to the ribbon movement as hereinafter described and particularly pointed out in the claims.

In, the accompanying drawings:Figure l is a front view of a machine embodying my invention; l i is a plan view; Figs. 3, 'i l3. 7 and 8 are views of (lGitlllH; Figs. 9, 10, 11 and 12 are views ,ot' further details.

I. hate shown my invention a; applied to a machine for printing addresses or the like from printing plates which are taken one by one from a hopper A. at the right of Fig. .l, and moved by a conveyor chain B to a point beneath an impression pad 8, which is operated vertically through an arm (3 from suitable operating connections. The paper or material upon which the impressions are made is fed into place ben ath the impression pad 8 in any suitable manner not accensary to describe herein hut disclosed in said application above referred 'o.

For making the imprenions, I employ 21 ribbon L extending over the path traversed by the priming plate and beneath the iniprcssion pad 8. This ribbon is attached at one end to a. ribbon reel to, Fire. 1, 2 and T, loosely mounted on a. sleeve M, which, in turn, is looaely mounted on'a pin aupportcd in the frame. This loose sleeve ll driven from the shaft B through a suitable h ll; and belt wheels I), 7), on the shaft B and the sleeve M, respectively. Driving, connection is made between the reel and the sleeve lll: by means of a friction spring l5 carried by the reel. and hearing upon tl.e loose sleeve. The ribbon extends i'rom this reel around a gni-zle pulley Y. and thence to a ribbon spool X fixed to a shatt- U, vith which is associated rib on reversing mechanism. This ribbon reversing mechanism also controls the movement and the teed of the ribbon, which is about one-eighth of an inch for each impression. This mechanism com-' prises an arm N mounted to swing about the axis of the ribbon spool shaft U, and connected by a lint: 0 with a portion of the yoke (5, so that movement is imparted to the disk arm N at each action of the yoke, and, consequently, once for each impression. This dish aria carries two pawls P and Q, pivoted thereto at n. and it has also pivoted at this point a pawl controlling arm The paWls l and Q are ada 'itctl to engage a ratchet wheel T, whi l1 fastened to the shaft U, and the direct. of rotation of the ratchet wheel T, with its ahat't ll, and consequently, the ribbon spool X. will do ventl upon which of the two pawls P and .over the roller 1", will, under this extra tension, impart movement to the said roller and its car vino lever Y against the tension 01. the spring Z. This lever will therefore swing laterally, and its arin Y will be thrown down to deprens a reversing stop C, removing the same reve rag lever B, which now alto, a to roving about the axis of the .hat't ll 1 arrestral by a stop S, said swinging movement being due to a spring l) hereinafter described. in this a tion of the reversing lever 5, its arm 3 carrying a pin #7 will *aune the shiftingof the pawl controlling arm ll. because of the engagement oi" the pin with the tor-lied end of the said controlling lever, and this controlling lever will therefore throw the engaged pawl out ol engagement with toothed wheel '7? and throw the diaengagctl pawl into action, no that the movement of the shaft ll will now he reve sod from that which it formerly had, to unwind the spool and allow the ribbon to unwind step by step tlwretrorn. about one-eighth of an inch at each action. 'lhe movement of the lever S is due to a torsional spring 1) connected to is in engagement witlrthe toothed wheel T.

therewith at one end surrounding the shaft,

and connected with a friction wheel E on the said shaft U. This wheel E is driven from the shaft U by a friction spring 6 within it, and a friction leather 0. As shown in Fi 's. 10 and 12. the wheel la has an Overhanging flange which receives the friction This wheel has also a stop pin 6 which,

when one revolution has been given to the wheel E and to the torsion spring, will strike against a stop pin a on the hub of the arm S, so that the torsion spring will be wound up sulficiently in this one revolution to have the required power for throwing the arm S when the stop pin C" is moved therefrom, and the torsional action willtakc place whether the shaft U is moved in one direction or the other. in order to place the main shaft U under a eel-tantamount of resistance, I provide friction washers V, V on each sideof the bearing 16 in which the shaft U is journaled, and I employ a tension spring VT to place-a pressure on these washers so that they will grip the bearing and hold the shaft firmly against movement, e20 ceptwhen the friction is overcome by the action of the driving pawl P or Q; carried by the lever ll.

Reverting to the action of the ribbon reel 15 in cmmection with the ribbon movement and reversing mechanism just described, it should be observed that tl 3 shaft l3 rotates one-half of a revolution for each impression, and therefore drives the. sleeve M upon which the ribbon reel is loosely mounted once for every impression. The friction spring 15- causes the ribbon "eel to rotate suliiciently to take up any s [ck when the ribbon is moving from right to left, at which time the ribbon spool X is be ing rotated step by step to unwind the ribbox so that it may pass therefrom and be.

wound on the reel 15, the action of each movement of the ribbon being about oneeighth of an inch, as above stated. When the ribbon is moved from left to right, the ribbon reel. 15 is rotated by the pull of the ribbon, dueto the feed mechanism, in an opposite, direction to the movement of the sleeve M, the friction connection between the sleeve and the ribbon reel serving merely to keep the proper tension on the ribbon,

and the operation is repeated. From the above it will be understood that the reversing actions take place immediately after the predetermined or substantially entire amount of ribbon has been wound on the spool, then unwinding begins, and when the ribbon has been fully unwound, the spool continues to rotate in the same direction to give an opposite rewind to the ribbon, and this movement is continued until the spool is again filled, when another reversing action takes place.

I claim as my invention 1. In combination, an impression member, an inking ribbon movement, including a ribbon spool at one end of the ribbon, with means for operating the same, a ribbon reel at the other end of said ribbon, connections moving in one direction only tending to 0perate the ribbon reel in one direction, including a rotary one direction friction member which, when the ribbon is to be wound on the reel, will drive the reel and which,

when the ribbon spool winds the ribbon, will tend to rotate the reel and thus place a, ten sion on the ribbon, substantially as described.

2. In combination, an impression member, a ribbon reel, a ribbon spool, driving means for the ribbon spool, reversing devices for changing the direction of movement of the ribbon spool, and a one-direction friction driving member for the ribbon reel to wind the ribbon thereon when it unwinds from. the spool and to permit the reel to reverse its movement by the pull of the ribbon when the spool winds the ribbon.

3. In cmnbination an impression member, a ribbon spool, connections for driving the ribbon spool, a reversing member for said connections, a driver for said reversing member to move the same for reversing the said connections, a detent for said reversing,
