UNITED STATES ALBERT B. KENNEDY, OI BOGKPOR'I', IN DIANAJ INKING ROLLER FOB TYPEWBI'IEB BIBBONS.

Application filed February 21, 1824. Serial No. 684,881.

My invention aims to provide-an improved device for re-inking typewriter and equivalent ribbons preferably without removing therin from the machines in which they are use In the accom anying drawings illustrating a preferred embodiment particularlyadapted for typewriter usez Figure 1 is a perspective view showing my im roved inking roller being applied to the rib on of a typewriter; V

Figure 2 is a top plan view ofthe-device;

Figure 3 isa section taken on the line 3-3 of Fig. 2; and

Figure 4 is an elevation of an inking element.

Referring to the illustrative embodiment of my invention, I have shown'my inking roller or wheel as comprising a disk 1 of absorbent material, preferably though not necessarily, built up of several thicknesses of felt or other suitable material, stitched loosely or otherwise conveniently secured to-' gether, (see Fig. 4), to produce a laminated wheel, which I have found in practice, gives good results.

These felt ceive, hold and give off the ink that is to be applied by the device, are suitably mounted to be brought into rolling contact with the ribbon that is to be inked.

In the embodiment of my invention here shown, said disks are mounted upon a hollow hub 2 upon which are also mounted two embracing disks or holders 3 adapted to be clamped together in suitable contact with the opposite sides of the disk roller, herein, by a clamping nut 4 threaded upon the hollow shaft and acting against a suitable abutment or shoulder, 5 upon said hub at the opposite side of said-roller.

This provides a self containedwheel with a hollow hub which may be journalled upon a pin or shaft 6 carried 'by-the' handle 7 which may convenientl'ybe held in one hand of the operator while manipulating the ribbon winding device by the other hand to draw the ribbon past and in contact with the roller for the purpose of re-inking the ribbon. As shown in Fig.1, the re-inking device may conveniently be applied to the ribbon at the point where it travels over and upon the customary ribbon guide upon the typewriter machine, but obviously any other suitable support for the traveling ribdisks which are intended to re bon may. be providedto suit the convenience .of the operator.'

Theinking roller of whatever material composedand'of whatever construction, is provided with one or more contained ink reservoirs herein provided by formin cesses or pockets 8 in the-respective dis s of which the roller is composed. As best shown in Fig.- 3, these ink receiving pockets or reservoirs are in re ister from one side to the otherof the in ing roller, but this is not essential since they maybe otherwise arranged to suit the preference of the maker or user.

However arranged and however formed in the inking roller, it will be observed that the roller together with the pockets or reservoirs is a self contained unit mounted to turn loosely upon the supportin shaft 6. Hence, there is no'likelihood of i which is supplied to the reservoir or reservoirs leak-' ing out to and upon the pin and back upon the handle to so1l.the handof the operator while using it. 1 The ink reservoirs as shown will ordinarily contain ink sufiicient for several re-inking operations and the ink may be brought to the surface of the roller either during the process of a single inking operation or following a considerable period of disuse by tightenmg the outer embracing or clamping disks 3 by turning the adjusting nut 4 u on the threaded hub'of the inking wheel. ile I have found lateral compressing of the inking wheel a convenient means of forcing ink from the contained reservoirs to the surface of the wheel or roller, obviously any other means for so expelling the ink may be employed if found more convenient.

My invention is not limited to the articular illustrated embodiment herein disclosed.

What I claim and desire to secure by Letters Patent is:

1. A re-inking device for typewriter ribbons and the like, comprising an inking roller of absorbent material, a self-contained ink reservoir formed therein, and clamping plates providing a closure for the reservoir and laterally adapted to expel ink therefrom.

2. A re-inking device for typewriter ribbons, comprising a roller of a sorbent material havmg a self-contained ink reservoir formed therein, a hollow hub for said roller, a pair of relatively adjustable clampin disks for the roller mounted on the hub an closing the reservoiri1 and a handle having a ing the disks and I. the self-contained ink shaft extending t rough the hub.

3. A re-inking device for typewriter ribbons and the like, comprising an inking roller of absorbent material having a plurality of ink reservoirs therein, a hollow hub on which said disk is mounted, and a pair of clamping disks for said roller mounted for relative adjustment on. said hub, said disks forming closures for said ink reservoirs and adapted to squeeze ink from the absorbent material to the periphery of the roller.

4. An inking dev ce comprising the roller 1 of absorbent material carried upon the hub 22, clamping disks 3 on opposite sides of the roller, stop shoulder 5 on the hub at one side of the roller, the adjusting nut 4 on the hub at the other side of the roller for adjustreservoirs 8 formed in the roller.

5. A reinking device. for typewriter ribbons and the like comprising a soft absorbent roller disk, a tubular hub carrying the disk, washer-like plates on opposite sides of the absorbent disk, an abutment on the hub for one of the plates, a nut on the other end of the hub abutting the other plate for s ueezing the disk between the plates, there y to regulate the flow of ink to the periphery thereof, a shaft projecting through the hub and a handle to which the shaft is secured substantially at right angles.

In testimony whereof, I have signed my name to this specification.

ALBERT H. KENNEDY.
