' a citizen of the United States, residing at ,Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Cash Registers, of which I declare the following to be a full, clear, and exact description.

' registers and like machines.

This inventionrelates to ink ribbon feed ing mechanism adapted for use with cash The subject matter of this application constitutes a division of co-pending applik .c ation of the same inventor,. numbered 451.508, and filed March 11, 1921. The rincipal object of this invention is to provide means under control of the rib-' bon itself whereby the ribbon will be given an extra long feed at certain points in its movement.

. -.With these and incidental objects in view,

the invention consists of certain novel features of construction and combinations of parts, the essential elements of which are set forth in appended claims and' a preferred form of embodiment of which is hereinafter described with reference to the drawings whichaccompany and form'part of this specification.

Of said figures: Fig. 1 is a side mechanism. I

Fig. 2 is a detail side elevation of the cam and pitman for operating the ribbon feed.

Fig. 3 is a detail top plan view of the elevation. of the ribbon ratchet and pawls for feeding the ribbon.

Fig. 4 is a'detail side view of the feeding ratchet and its cooperating pawls.

General desm'z'ptz'on;

The printing mechanism disclosed com:v

prises two sets of printing wheels or elements 19 and 20 with which suitable-impression hammers 21 and'22cooperate to produce impressions on a detail strip 23 and a slip 24 through afribbon 25. The ribbon is sewed so as to make it a continuous ribbon and cooperates with both sets of printing elements. It was found that when the seam in the ribbon came opposite either type line ent invention contemplates so constructing the feeding mechanism that when the seam in the ribbon approaches either printing The presare supported by studs 29 projecting from a frame 30. This method ofmounting is convenient in that by removing the above mentioned plate the entire ribbon and ink roll may be removed from themachine.

A tension is maintained on the ribbon 25 by a roller31 on a rod 32 (Fig. 1) supported by parallel arms 33 (only one of which is shown), loose on a stud 34 mounted in the frame 30 and supported at its outer end by the above mentioned plate The roller is held against the ribbon by gravity.

Clutched tothe roller 27 by any suitable means (Figs. 3 and 4) is a ratchet 35. Loose on the stud 36 which supports the ink roller is an arm- 37 carrying a springpresseddriving pawl '38 engaging the ratcha stud on the frame and a flat-sided stud 45 on the link 39 holds thepin in engage- 'ment with a toe 46 of an arm 47 loose on a stud 34 thereby limiting the downward movement of the link 39.

The lever 42 is rocked firstcounter-clock- I wise and then clockwise (Fig. 1) by means of the following mechanism. Fast on the shaft 43 is an arm 49 (Figs. 1 and 2) to a which is pivoted one end of a pitman 50. This pitman at its otherend is slotted to surround a hub 59 of a cam 54 fast on a shaft 51, which receives one complete counter-clockwise revolution upon each operation of the machine. The pitman 50 carries an anti-friction.roller 52 cooperating with a cam groove 53 in the cam 54; The shape of the cam} groove 53 is such that the pitman rocking arm 49, shaft 43 and lever 42 counis moved first to the left and then towards the right back to home position, thereby its highest position, and when the lever ter-clockwise and then clockwise. Near the end of the counter-clockwise movement of said lever the pm 41 engages the end ot the slot 40 and moves the link 39 upward, there spring 44 lowers the link 39 and returns the arm 37 and pawl 38 to the position shown in Fig. 4. A spring-pressed retaining pawl 56 prevents clockwise or retrograde movement of the ratchet 35.

The ribbon has a transversely extending seam 57 (Fig. 1) and, as an impression through said seam would not be clear. a mechanism is provided for feeding the ribbon a greater distance as the seam approaches the printing lines so that it never stops at these lines.

Secured to the ribbon are two metal buttons 60 cooperating with a flange ($1 of an arm 62 rigid with the ar1n47. IVhen one of the buttons 60 engages the flange 61 during the movement of the ribbon, it rocks the arms 62 and 47 clockwise and disengages the toe 4.6 from the stud 45 thereby allowing the spring 44 to move the link 39 downward, whereby the end of the slot 40 is moved close to the pin 41. Downward movement of the link 39 also rocks the arm 37 a greater distance than previously described.

IVith the parts in the positions just mentioned, the pin 41 engages the upper end of the slot 40 during the first part of the counter-clockwise movement of the lever 42 and .moves the link 39 upward, whereupon the arm 37 is rocked counter-clockwise. As this movement of the link 39 and arm 37 is much greater than that previously described, it is clear that the ribbon is fed agreater distance than when the button 60 does not rock the arms 62 and 47 to disengage the toe 46 from the pin 45. During this movement of the ribbon the button (30 which caused the long feed is moved past the flange 61 on arm 62 so that the arm 47 by its own weight is rocked counter-clockwise after the pin has been moved to 42 is rocked clockwise to its normal position the spring 44 pulls the link 39 downward until the stud 45 again ei'igages the too 46 ion the arm 47. The lower edge of the toe .46 is'sh aped so that the upper surface of the stud 45 can cam the arm 47 clockwise to permit the link 39 to complete its upward movement in case the 'button leaves the flange 61 during the first part of the upward movement of the link 39. These two buttons are so positioned on the ribbon that the seam 57 is always ted past the printing lines and therefore no impression is ever taken on said seam.

IVhile the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the one form ot" the combination of an inking ribbon, a seam therein, type carriers, means for feeding said ribbon over said type carriers, and means under control of said ribbon and operable as the seam approaches said carriers for controlling said feeding means to feed said seam from one side of said type carriers to the other.
