. Whatmaybe calleda casing is represented at 2: and :in i the form :shown :this is: round although itsmay-be of any othershape. Preferably it'has a. bottom wall 4: and'a peripheral side wall 6', as shown in Fig; 2.

2 A-pair of. spaced armmembers 8tare provided and :these extend: forwardly from; the casing.

t Then-between these: arms. 8 there is. disposed a pair" ofrco-operating rolls Ill and 12; The roll lll lias trunnions l 4' rotatable ,in'the arms 8-while trunnions IS :on r0111 l2 are disposed in longitudie nal sl'ots,..such.as l8, provided inthewarms.

The 'said slots I8' have downwardly depending portions 1 2ll- (see Fig. 2i) t and there. :is. provided whatmay becalled a roll release member 22. This has side members 24 .and'a transverse member 26 and the trunnions 16 of roll l2 are rotat- 50 able-inithe-side members 24.

Imthisway; by m'oving the member 22 forward and back the trunnions 1B of roll I2 are moved along the slots l8 of arms 8.

The parts are so arranged that when the mem- 55 ber 22 is in its rear position the roll i2 is brought ing:description of the preferred form thereof, ref- 7 into engagementwith roll IEI and, of course, when the: member-v 22 is forward, the rolls are out of contact. In thedrawing, the member 22isshownin a forward position whereby the rollsv l0 and l2i-are out of contact; 7 l' A spring having end partsMextending through thereanends of members 24. and held by a re tainer .469may be provided-to urge the member 22z iearwardly; Thus, when; the member 22 is elevatedfrom the. position shown in. Fig. 2 so thatthe trunnions .I 6 are out of slots 29; the said trunnions, may slide rearwardly in slots I8; of arms 8-sothat the rolls l0 and 12 are normally held in yielding contact.

A U-shaped bracketmember 34 is preferably associated with the casing and a rod 361s guided for sliding. movements therein. The. rear end of rod 36' may, extend through an opening in the rear part of wall 6 of the casing and a coil spring 3821s preferably provided on the rod so as to; abut .20 the wall of? the case-and-urge the member 34 forwardly.-

A resilient pad member is disposed Within the casing and-it has a part associated with part 3.4; Thus, it will be seen, the spring 38 causes 5 the pad to yieldingly bear againstthe rear roll Ink or other material, which it is desired to apply to the ribbon, is applied to the ink absorbing member 30 and of course the ink'is fed 30 onto roll lll thereby. If desired, an upper wall part such as M! shown in Fig. 4 may be provided in association with the casing and this is to prevent inkfrom flowing outrthe. casing in the event it ,is desired to use the device. while disposed on its side.

Acover such as 25 is provided for fitting 'on thecasing-and, as shown in Fig. 5, this preferably has aguide member 32,. Thus, in operation, as shown in Fig. 2;a ribbon Rmay be led forwardly through 40 the guide 32 and over roll Iii. As stated, by moving member 22 forwardly the roll I2 is moved away from; i 0,250 that the ribbon R may go therebetween. Then by releasing member 22, roll I2 is caused to bear on-the-ribbon and as the ribbon R is drawnthrough the' rolls they are rotated.

Accordingitothe preferredform of the invention; part Zii-of member 22 is formed to facilitate handling thereof and the, arms 24 are so ar-" ranged that in the event that roll it! has been suppliedwithztan 'excessamount of ink and! it; is not desired to have the roll apply ink to the ribbon, the forward end of member 22 may be the trunnions M of roll H] to retard or stop rotation thereof.

The ink absorbing member indicated by 30 may extend around the casing as indicated in Fig. 1 or it may be of some other form. It preferably consists of felt or the like, and, as stated, it has a portion carried in carrier member 34 and in contact with roll IE].

While we have described the invention in great detail and with respect to a preferred form thereof, it is not desired to be limited thereto since many changes and modifications may be made therein without departing from the spirit and scope of the invention.

What it is desired to claim and secure by Letters Patent of the United States is:

1. A device for applying ink or the like to a typewriter ribbon or the like comprising in combination, a casing in the form of a receptacle having spaced arms extending forwardly therefrom each provided with a longitudinally-extending slot and a communicating transverse slot at the outer end thereof, an inner roll journalled in said arms for rotation therebetween, an inking pad disposed in said casing having a part for contacting with said inner roll, a roll-release member having a pair of side arms disposed adjacent the first-named arms, an outer roll between the arms of the said release member having trunnions rotatable therein and disposed in and movable relative to said slots, and spring means associated with said casing and said arms of the release member urging the latter inwardly towards the casing, all adapted and arranged whereby the release member may be moved against the action of the spring means from an inner position where the rolls are in engagement to an outer position by sliding the trunnions of the outer roll along the longitudinal slots of the spaced arms and into the transverse slots thereof so that the release member is held against inward movement with the rolls in separated relation against the action of the spring means.

2. A device for applying ink or the like to a typewriter ribbon or the like comprising in combination, a casing in the form of a receptacle, spaced arms extending forwardly of the casing having longitudinally extending substantially straight slots terminating in transverse slots at the outer ends thereof, an inner roll having trunnions rotatable in said arms, a release member having arms adjacent said spaced arms provided with trunnion engaging portions, an outer roll at a side of the inner roll remote from the casing rotatable between the arms of the release member having trunnions therein which are disposed in and for movement along the slots of the spaced arms, and spring means associated with said casing and release member urging the latter inwardly towards the former, all adapted and arranged whereby the release member may be moved outwardly from the casing against the action of the spring means to move the trunnions of the outer roll along the longitudinal slots of the spaced arms-and into the transverse slots to separate the rolls by a substantially straight line movement and hold the said rolls in separated relation or the arms of the release member when the rolls are engaged may be oscillated on the trunnions of the outer roll so that the engaging portions thereof bear on the trunnions of the inner roll to retard rotation thereof.
