My invention support-s the ink in a sub, stantially inclosed and stationary receptacleconstantly stirs and mixes the ink for preventing separation and thickening of its coloring-matter, and feeds the ink positively and uniformly from the receptacle to the marker without permitting variation in the color or consistency of the ink or variation of the uniformity with which the ink is fed.

A represents the ink-receptacle, which is of any desirable form and construction suitable for use with the remaining parts of my invention and is preferably formed of sufficient size to contain a considerable quantity of the ink. As illustrated, the receptacle consists of a stationary body or lower section a, removably secured in any desired manner to a suitable supporting-frame B, and a cover or top section a, removably secured to the body or lower section a. As best seen at Figs. l, 2, 3, 4, and 7, one side of the body or lower section cr is secured to the frame B by a screw b, provided upon said frame and engaged with a slotted lug a2, projecting from said side of the body or lower section a, and a second side of the body or lower section a is secured to the frame B by a thumb-screw b', passed through a lug a3, projecting from the body or lower section aand having its lower end engaged with the frame B. As also best seen in Figs. l, 2, 3, 4, and 7, one side of the cover or top section c' is provided with ashoulder a4, which enters a corresponding perforation @5in the body or lower section a, and a second side of the cover is provided with a shoulder a6, removably engaged with a yielding shoulder a7, secured to the body or lower section a. The receptacle A is thus firmly held in operative position and is readily detached at will for cleaning or other purposes, and its cover is also firmly held in position and may be easily removed for permitting entrance to the receptacle.

C represents any suitable construction of marker to which the inl; is fed from the receptacle A, the marker here illustrated being shown as rotary and as mounted upon a shaft c. The marker forms no part of my present invention, and consequently it is unnecessary to further illustrate or describe the same.

D is a loosely-revoluble ink feeding or distributing roller having a flexible face engaging the face of the marker C for transmitting ink thereto. As preferably constructed the roller D is provided with a face of felt and is adjustably secured to a movable support E, provided with a bearing or barrel c, movably supported or pivoted upon a rod or other su pport El, which, if desired, may be secured to the frame B. A spindle d for the roller D is passed lengthwise therethrough and is provided at its upper end with a removable nut d', arranged above the upper face of the roller D. The lower end of the spindle d is passed through a slot c in the support E and is provided with a shoulder d2, movable in said slot, a shoulder d3, resting upon the top face of the support E, and an adjustable shoulder d4, bearing again st the lower face of said sup- Ort.

p F is an ink-feeding .roller provided with a substantially rigid face, to which the ink is fed by the ink-applier presently described, and, as clearly seen in the drawings, the face of this roller bears against the face of the loosely-revoluble roller D and revolves the same for feeding the ink from the roller F to the roller D and thence to the marker C.

The roller F is mounted upon a spindle f, j ournaled in a support E2, pivoted to a rod E3, carried by the support E, and said roller is alined with an opening A in.an upright wall of the cover or top section a' of the ink-receptacle, and a portion of its face projects beyond the upper end of a face A2 of the cover ortop sectionct, projecting downwardly within the receptacle A for conducting within the same any ink dripping from said portion of the roller F or the ink-applier presently described. A suitable adjuster or screw E4 is movable in the support E and bears against the support E2 for varying the position thereof and forcing the roller F against the roller D and varying its frictional engagement therewith. A spring is secured to the support E and bears against the support E2f0r forcing the support E2 against the adjuster E3.

The roller F is revolved by an actuator of any suitable form, size, and construction, here illustrated as a shaft f provided with a gear-wheel f2, to which motion is communicated by any suitable form of power-transmitting mechanism, not necessary to herein illustrate or describe. This actuator or shaft f is revolved in fixed bearings, and as the roller F is necessarily adjustably supported I connect the shaft f to the spindle f by a flexible connection F', consisting of a section f3 of a shaft having its opposite ends provided with projecting pins f4, engaged with slots f5 in heads provided upon the adjacent ends of the spindlefand the shaft f. It is evident, however, that other constructions of fiexible connections may be interposed between the spindle fand the shaft f.

It is extremely desirable to adjust the support E, carrying the ink-feeding rollers D F, and consequently I provide said support with a projecting arm EG, formed with a groove E7, andan engaging face E8, provided with an engaging shoulder E9. A suitable adjuster G is engaged with the arm Ei for varying its position, and consists, preferably, of a rod having one extremity mounted upon a pivot g, carried by any suitable support g', only a portion of which is here illustrated, and its other extremity movable within the groove E7 and provided with an adjustable shoulder c 2, movable lengthwise thereon and bearing against the face E8 and provided with sockets g3 for receiving vthe shoulder Ei'. A spring g4 is mounted on the adjuster G for forcing the arm EG of the support E against the shoulder g2 of the adjuster G and engaging the shoul- IOO IIO

der E9 with the socket g3, registered therewith. This is a particularly simple, practical, and effective mechanism for feeding the ink from the ink-applier to the marker C, and as but a single roller having a fiexible face is used the liability of` straining and separating the coloring-matter of the ink when in transit to the marker is reduced to a minimum. Moreover, 'as the face of the positively-driven roller iscomparatively rigid and frictionally engages the additional feeding or distributing roller, the speed with which the ink is fed by the distributing-roller is uniform, the Wear upon the distributing-roller is reduced to a minimum, and the frictional engagement of the positively-driven roller with the looselyrevoluble distributing-roller prevents the same from losing its normal circular form, which result Would take place were it engaged by a second roller having a yielding face. Theink-feedin g rollers and their supports are also so constructed as to be readily adjustable toward each other and toward the marker, and this great capability of adjustment is an additional feature of advantage of 'the described construction of ink-feeding rollers and supports therefor.

I-I represents the ink-applier, which is of any suitable form, size, and construction for feeding the ink from the receptacle A to the roller F. The preferable construction of inkapplier consists of a frame i1., formed with a groove or guideway h', and a feeding-strip h2, yieldingly supported in the groove or guide h and formed with a suitable feeding- Vface which, when in its operative position,

isalined with andcaused to project through the outlet-opening A for feeding the ink to the roller F or any other suitable ink-feedin g part. Suitable springs t'are supported by the frame 7i and are operated to force the feeding-piece h2 to its normal position relative to the frame h and permit the same to yield or move within the groove or guide 7L when the feeding-strip'is engaged with the roller F. The feeding-strip 77,2 is provided with a slot 7V* for receiving a pin h5, which is secured to the frame h and acts as a stop for said strip and as a guide therefor when the strip is forced backwardly against the action of the springs h3.

It will be evident to those skilled in the art that any other feeding part may be used instead of the roller F for receiving the ink fed from the receptacle A by the ink-applier H; that said ink-applier may,if d esired, be form ed with a comparatively rigid instead of a yielding feeding-faee,and that, providing the roller F or other part to which the ink is fed projects within the cover or top section a of the ink-receptacle A, it is unnecessary to project the feeding-face of the ink-applier through the opening A. It will also be evident that the roller F, to which the ink is applied, may be supported Within the upper `extremity of the receptacle A instead of at the outside thereof and that the ink-applier may then feed the ink to said roller and the roller feed the ink from the receptacle A.

The preferable form of ink-applier H is arranged normally, as best seen at Fig. 3, in the lower portion of the receptacle A and is movable upwardly into alinement with the opening A, and thereby continually agitates and mixes-the ink Within the receptacle, preventing separation and thickening of the coloringmatter of the ink. This ink-applier is supported by an arm H', which also acts as an agitator of the ink Within the receptacle A. As preferably constructed the arm H consists of a section H2, secured to a rock-shaft A3, journaled in the coveror top section a', and a rocking section H4, movable in a plane extending at an angle with the plane of movement of the former section and having one end suitably supported by the section I-land the other end secured to the ink-applier H. A spring H5 surrounds a portion of the rocking section H4, and as the `arm H is elevated an antifriction-roller H6 uponV the frame of the ink-applier H engages a face as, formed upon the interior of the cover or top section a, and the ink-applier H is caused to assume an upright position and its feeding-face is alined with and projected through the opening A.

The rock-shaft H3 projects beyond one of the upright walls of the cover or top section ct and a crank-arm I is fixed thereto for actua-ting the arm H. A rotary shaft t', suitably supported by the frame B, is connected to the crank-arm I for rocking the same, and when myimproved inker is used in connection with a machine for postmarking and stampcanceling mail-matter any of the shafts of said machine maybe used as the shaft z', providing it runs at al suitable speed for eifecting the desired number of oscillations of the crank-arm Iand the arm H for supporting and operating the ink-applier. As here illustrated, this shaftt' is provided with a gearwheelfi, to which power is transmitted by any desired mechanism, not necessary to herein illustrate or describe, and is also formed with a worm i2, meshing with a worm-Wheel i3, secured to a shaft 4. A bracket t5 is suitably secured to the frame B or other desirable support and is formed with journaled bearings for the shaft it, and said shaft is provided with a disk i6, eccentrically connected to one extremity of a link or pitman 7, having` its other end provided with a hand-piece 8, removably engaged in any desired manner with the crank-arm I for transmitting motion thereto. As the shaft t' rotates, the crankarm I is rocked oroscillated, and each revolution of the disk i6 oscillates the ink-applier from its normal position in the lower portion of the receptacle A into its operativeposition in alinement with the opening A for feeding Y the ink from the receptacle A to the roller E, and then returns said ink-applier to its normal position.

The shaft t' is suitably connected to the actuator or shaft f for the iuk-feedin g rollerF by IOO IIO

any suitable construction of power-transmitting mechanism, not necessary to herein illustrate or describe, so that said shafts are revolved con jointly.

At Fig. 12 I have shown a slightly-modified form of my ink-applier, in which the ink-feeding piece consists of a roller hw, j ournaled in a frame 71,11, secured to a movable section h1? of a supporting-arm.

The operation of my invention, which will be readily understood upon reference to the description and the accompanying drawings, is as follows: The ink-applier is continually oscillated from its normal to its operative position for feeding the ink, and the movement of said ink-applier and its supportingarm continually agitates and stirs the ink, preventing separation and thickening of its coloring-matter and maintaining the same at a uniform consistency,v and the ink-feeding rollers feed the ink from the ink-applier to the marker constantly and effectively Without straining or separating the coloring-inatter thereof, and consequently the impression produced by the marker is of uniform color and legibility.

The parts of myinvention are economically manufactured and assembled and are evidently durable in use, and the entrance of dust, dac., to the ink is practically prevented, as, with the exception of the small opening in its cover or top section, from which the ink is fed, the ink-containing receptacle is entirely closed. The ink-receptacle is also readily cleaned and refilled. The inking-rollers and the supports therefor are readily and practically adjustable, and owing to the peculiar construction of the foregoing parts and the ink-applier myinvention requires a minimum amount of attention, as the same is entirely automatic in its operation and feeds the ink with great uniformity and constancy Without liability of derangement of any of its parts. It is evident, however, that the detail construction and arrangement of the parts of my inker may be considerably varied Without departing from the spirit of my invention. Hence I do not herein specifically limit myself to such exactdetail construction and arrangement.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
