INKER FOR TYPEWRITERr-RIBBONS- Application filed December 27, 1920. ,Serial No. 433,318.

To all whom it may concern:

Be it known that I, WILLIAM R. ORMES, of Waltham, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Inkers for Typewriter Ribbons, of which the following is a specification.

My invention is designed to serve as a desk or ofiice appliance for the reinking or remoistening of typewriter ribbons. The ink on ribbons dries in time and they are often thrown away 'when in fact the fabric has considerable life provided it can be remoistened or reinked. Usually under these conditions the ribbon is thrown away, whereas all that is necessary to revive it is to apply to it some proper liquid. Heretofore as far as I know machines useful for reviving ribbons have not been adapted for ordinary ofiice use. They have been quite large and complicated and particularly adapted for use in factories where the ribbon is manufactured.

My invention will be understood by reference to the drawings, in which Figure-1 is a side elevation of a machine embodying my invention;

Fig. 2 a plan thereof;

Fig. 3 an end elevation showing the support for one of the reels;

Figs. 4 and 5 sections on lines 4-4 and 55 of Fig. 2; and

Fig. 6 a perspective view of the moistening tank.

A is a table which may be of wood or other suitable material on which is mounted a base plate B havin projecting upwardly therefrom a rib C. Ihis rib is shaped at each end as shown at D, E, to form bearings for studs (1, e on which the reels are mounted, it being understood that the reels herein referred toare reels of ordinar character used in typewriting machines. n the stud d is mounted a crank/arm F with a suitable crank handle, bearirigs F being provided therefor in any suitable manner. The end of thestud d is threaded to receive a nut' d by which a reel is clamped onto the stud against the washer (i so that it may be rotated by the crank. At the other end of the device the means for holding a reel upon the stud 6 comprises a rod G mounted to slide lengthwise and free to turn in the rib C and a bearing 0 its outer end being bent laterally as atg and provided-with a perforation Specification of Letters Patent.

1 to fit over the end of the'stud e. The other end of the rod G carries a head g. Against this head presses one end of a leaf spring G the other end of which is riveted at Gr to the rib C. By pressing the rod G inwardly by means of the head 9 and against the force of the spring-Gr the arm 9 is pushed off from the stud e to enable the reel to be put in place on the stud, and when the head 9 is again released the spring G forces it toward the position shown in Fig. 2 so that the perforation g being guided by hand onto the stud e rests against the reel and not only holds the reel in place, but applies friction' to it so that it will not run on the stud and render the ribbon slack.

On the rib C is mounted a cradle H for the tank J which contains the moistening liquid. In practice I prefer to make my base plate B of two thicknesses of metal which are riveted or otherwise attached together and are shaped and bent as indicated in Fig. 5 so that the rib C is of double thickness, while the ends or edges of the. plate are bent' outward to form the bed plate B, the upper edge eing bent outward and otherwise suitably shaped to form the cradle H. This cradle has an end piece h and side pieces b so that it may be easily slid into place and removed.

The tank is of rectangular shape, its cover J being slotted as at 7' so that a wick may be placed in the tank with its end pfiqecting through the slot to engage the roll and the tank partially filled wlth a liquid which shall moisten the wick and so carry moisture to the moistening roll L'. Thisroll is carried in uprights Z projecting from the top of the tank, and in order to facllitate the removal and replacing of the roll, as may be deslrable when filling the tank, I prefer that these up-- rights Z shall be so made that the roll maybe sprung into or out of place. On each side of the roll and on top of the tank I mount guide fingers m preferably curved in cross section as shown and projecting from a base M, so that the whole device may be struck out of a single strip of material whi h is attached as 'a unit to the top of the ta This whole construction. facilitates economical manufacture, for with the exception of; the studs, rod, crank bearings, etc., it may be died out from sheet metal at very little expense." In using my device, the rod 1s first ressed ins hat the arm-y wlthdm'wn from the stud e and on that stud a reel wound with dead ribbon, for example of ordinary typewriter form, is placed. The rod G is then released and the arm 9 guided back on the stud 6 so that it presses the reel against the opposing wall of the part E of the rib C. A portion of the ribbon is then drawn off from the reel N, passed under the nearest guide finger m, over the roll L, under the other finger m and onto an empty reel H which has been put upon the stud d, the nut (1* being first removed. The nut is then screwed home against the reel N so that this reel will turn with the crank, and the free endof the ribbon is then attached thereto. The turning of the crank draws the ribbon over the roll L which is kept moist by the wick K from which it absorbs either a reviving liquid or fresh ink as the case may be. The reel filled with the moistened ribbon may then be removed and inserted in the typewriter in the usual way where it will be found ready for use if the process has been properly and sufficiently carried out. If thought best the ribbon may be run through the machine more than once.

It will be seen that this device is of great simplicity and may be made at comparatively little expense because its size, shape and referred method of making are such that its main portion may be stamped out of ordinary sheet metal, and moreover when finlshed 1t is of such size, say SIX or seven inches long, that-it takes up but little room a mois-' Other ways of embodying my invention will occur to those skilled in the art as I do not mean to limit myself tothe precise construction shown.

What I claim as my invention is 1. A device of the kind described comprising a base having reel supports mounted thereon, a tank support mounted between said reel supports, a tank detachably mounted in said tank support, a roll, a roll mounted on said tank, and guides mounted on said tank'one on each side of said roll, one of said reel supports carrying a crankarm and the other having means adapted to apply tension to a reel mounted thereon.

2. In a device of the kind described, a reel support comprising a plate, a stud mounted in said plate, a slidable rod mounted in said plate and having a perforated arm at one end, the perforation of said arm being adapted'to slide over .said stud and hold a' reel against said plate, and a spring arm one end of which is attached to said support and the other adapted to engage said rod whereby said arm will be maintained in frictional contact with said reel;

3. In a device of the kind described, two reel supports having a cradle located between them, a tank detachably located in said cradle, a roll mounted on said tank, guides located one on each side of said roll, and means located in said tank whereby said roll may be moistened.

4. A device of the kind described comprising -two reel supports, a crank shaft mounted in one of said supports, a frictioncontrolled rod mounted in'the other support to carry a reel, and amoistening device located between said reel supports and comprising a moistening roll and 'means for moistening it, and guides to hold a ribbon in contact with said roll.
