PATENT MATTHEW J. DOLPHIN, ,OF BROOKLYN, NEW YORK.

INKINGY DEVICE.

SPECIFICATION forming part of Letters Patent No. 449,110, dated March 31, 1891. Application filed November 9, 1889i Serial l lo. 329,721. (No model.)

To all whom it may concern:

Be it known that I, MATTHEW J. DOLPHIN,

of Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Inking Devices, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description. I My invention relates to an improved inker, and has for its object the production of a simple and effective device which rapidly, continuously, and evenly feeds ink to the'marker of a marking-machine; and to this end it consists, essentially, in a suitable ink reservoir or holder,a feeding-surface connected to said reservoir or holder, a regulator for governing the flow of the ink from the holder or reservoir, an inking-roller, and an intermediate roller for feeding the ink .from the feedingsurface of the inking reservoir or holder to said inking-roller.

It also consists in auxiliary spreading-rollers for aiding the even distribution of the ink upon the inking-roller; and it furthermore consists in the detail, construction, and arrangement of the parts, all as hereinafter more particularly described, and pointed out in the claims.

In specifying this invention reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views.

Figure 1 is a top plan view of my improved inker. Fig. 2 is an elevation of the parts as illustrated in Fig. 1. Fig. 3 is a horizontal sectional view taken on line as as, Fig. 2, particularl y illustrating the relative arran gem ent of the rollers of my improved inker. Fig. 4 is a sectional view taken on line y y, Fig. 3. Fig. 5 is an elevation of the detached inkfeeding regulator. Fig. 6 is a top plan view of the regulator illustrated in Fig. 5. Fig. 7 is an inverted plan view of the filling-piece or cover of the ink-containing reservoir. Figs. 8 and 9 are respectively top and inverted plan views of the detached extremity of a support for my inker, illustrating particularly the fine adjusting device therefor. Fig. 10 is an elevation of an evening-roller for effecting the even distribution of the ink, and Fig. 11 is a detail elevation illustrating an additional evening-roller.

The table or other support A for the inking device may consist of the supporting-table for a marking-machine of the usualor any special construction. Mounted upon this table is the bracket B, which preferably carries the several parts of my inventionnamely, the feeding or ink-containing roller 0, the inking or spreading roller G, the intermediary roller F, and the eveners H and J.

Supported in suitable proximity to my inker is the marker a, which may be of any suitable form, size, or construction, but is here illustrated as the one described and claimed in the patent of August Bertram, No. 408,401, issued August 6, 1889. This marking-roller is mounted upon the shaft a, and consists of the continuously-revolving portion or drum a and the printing portion or marker a normally at rest until a clutch a is operated by the advancing letter to connect said marker to drum a The marker then makes a com plete revolution, whereupon the clutch disengages the same from the drum, and the rotation of the marker ceases until the clutch is again operated by another letter.

The ink-containing roller 0 is of substantially the same construction as that illustrated and described in my pending application, Serial No. 823,946, filed September 14:, 1889, and possesses the additional features of advantage-namely, that the same may be readily removed from the remaining portion of the inker without stopping the operation of the marking-machine or soiling the hands of the operator, and that the feed of the ink is more readily and positively controlled. This roller 0, as best illustrated in Fig. 4, is mounted on a bracket 0, hinged at c to the bracket B, and is provided with an ink-containing reservoir or receptacle, which preferably consists of a cavity or recess 0', formed within said roller by constructing the same of tubular shape. Passing from the interior to the outside of said roller 0 are a suitable number of openings or passages 0 through which the ink is fed to an outside feeding-surface C The preferable manner of rendering this roller 0 readily removable from the remaining portion of the inker consists in rotating the same frictionally and mounting it upon a spindle C formed or provided on the bracket B.

This spindle is engaged bya socket 0 formed in an upwardly-extending hub 0 rigidly secured to the base C of the inking-roller. As will be presently described, the ink is fed to the cavity G and the flow thereof is governed by a regulatorD of suitable form and construction. The preferable form of regulator consists of a sleeve provided with openings (Z, registering with the openings 0 of the roller (I. As best illustrated, these openings are formed at one side thereof with the grooves (1 leading therefrom.

hen the sleeve D is inserted to its normal position within the roller (J, no flow of theink is allowed, since these parts are so formed that the openings 0 and (l are out of alignment with each other. However, by turning the sleeve D within the roller 0, as will be presently set forth, the grooves 61', and finally the openings (Z, maybe registered with the openings 0' These grooves are a feature of great advantage, since when in operation the ink-containing roller is revolved with considerable rapidity, and the centrifugal force generated causes the ink to flow with a greater force than desired when the openings 0 and (Z are registered with each other, even though, as illustrated, these openings are few in numher and of comparatively small size. However, by adjusting or partially rotating the sleeve D the flow may be regulated to a nicety, as desired, since as the sleeve is adjusted the grooves d are registered with the openings 0 and as these grooves grow gradually larger in area a consequent increasing llow of the ink is produced until the desired feed is produced. This feature is of particular advantage, since it enables my inker to be used with dilferent kinds of ink, as must necessarily be the case when the same is desired for use upon different printing or markin g machines.

Provided at the upper part of the sleeve D is the disk or plate D, preferably formed integral therewith and provided with the openin g D into which the ink is readily inserted without withdrawing said sleeve from the roller G. Above said disk is the filling-piece or cover E, which is secured to said disk by means of suitable lugs or pins e, secured to said disk and engaging openings 6' in the cover E. As best seen in Fig. 2, the said filling-piece is provided with the outwardly-projecting pin 0 which engages a right-angular slot or cut-out c in the said roller C, securely retaining the parts together and allowing the adjusting movement of the sleeve D within the roller 0 to be readily determined by the position of said pin within the slot. It will be noted that one extremity of the slot or guide 0 extends horizontally and the other extremity extends vertically to the edge of the sleeve G to admit the entrance of the pin e Rig-idly secured to the disk D is a projecting pin 1), passing through an opening in the filling-piece E, and provided at the top with a nut D screwing thereupon and firmly securing said filling-piece in its desired position upon the pin e.

In order to best cover the opening D I provide on the under side of the filling-piece E the rubber packing D which tits over the opening D Diametrically opposite to said piece D is a like piece D, which brings about the even bearing of the filling-piece E d prevents cramping of the parts.

Contacting with the feeding-surface of the roller C is the intermediary roller F, which is preferably provided with a face of gelatine or other suitable yielding substance, and is revolved continuously by means of suitable gearing or otherpower-transmitting m echanism F, connecting the shaft of said roller to the shaft a of the marking-roller a.

The ink-containing roller 0 is preferably revolved by friction with the roller F, and this can be increased at will by loosening the screw a, forcing together said rollers, and then tightening the screw. Contacting with the roller F, and also with the marker at at each revolution thereof, is the ink-distributing roller G, which thus feeds the ink to the marker. This roller is provided with a face of. felt or other suitable yielding material, and is movable toward the auxiliary roller F in order to increase the friction between said rollers and render positive thedriving of the roller G by the roller F.

As best seen in Fig. 4, the pivotal pin G of the roller G is provided with its lower extremity screw-threaded and engaging a sliding piece g, working in a slot b in the under side of the bracket B. This block g is provided with the upwardly-extending portion 9, of less width than the base of the sliding piece g, and guided in the slot Z). \Vhen the pivotal pin G is screwed clown- Ward, the face f, formed upon said block, is drawn against the face I) of the bracket B, and the friction of the parts holds said block and pin in their adjusted position. In order to facilitate the revolution of the roller G, it is advisable to interpose a washer between the same and the bracket B, as, while it is necessary that the said roller should be held in its adjusted position, it is also necessary that it should revolve with great case, so that but little wear will be occasioned. This arrangement of the i nk-con taining roller, inking or distributing roller, and auxiliary roller brings about a very even distribution of the ink, which is an essential point, and has heretofore been but imperfectly produced. This even distribution is further aided by an evener H, which preferably consists of a roller journaled in a bracked II, mounted upon the spring I, which is secured to a post 1, provided upon the bracket B. The evening-roller H thus bears against the distributingsurface of the ink-containing roller with a constant pressure and evenly spreads the ink thereupon before it is taken or wiped oif by the roller F.

IIO

In some cases it frequently becomes advisable to use an additional evening-roller, and

' this I prefer to mount so as to operate upon the intermediary roller F. This second evening-roller J is preferably movable up and down the periphery of the roller F, and this desirable result I obtain by loosely mounting the said roller upon its pivotal pinj, forming a cam-face J upon the lower extremity thereof, and engaging the same with a pin or lug j, provided upon its supporting-post.

The ink-distributing roller is preferably revolved by friction, and it will be seen that upon its operation the said evening-roller J is moved up and down, according to the engagement of the elevation or depression of its uneven surface with the pin 3'.

In order to render my inker effective, it is necessary that the same be adjustable toward and away from the marker D, and this is preferably produced by pivoting said bracket by a pin B, which engages a slot 15 in the bracket. In order to produce the best results, itis necessary, however, to effect a fine adjustment of the bracket, and accordingly, as i n myprevious application, I provide therein a slot B which engages a pin B", projecting from the frame A. Guided in the bracket B and entering the slot B is a screw E the extremity of which bears against the npwardly-projectinglug or pin B. When desired to adjust the bracket B upon the table A, the screwor bolt B is loosened and the screw B is then operated to adjust the same to the desired position, whereupon the bolt B is screwed downward, retaining the bracket in its desired adjusted position.

The operation of myinventionwillbe readily perceived from the foregoing. and it will be readily understood that the feeding of the ink is positive, and that the same is distributed very evenly upon the die or marker D, thus rendering the impression of stamp thereof clear and effective. It will, however, be understood that considerable change may be made in the relative construction and arrangement of the parts of my invention without departing from the spirit thereof. Hence I do not limit myself to its precise described form and construction.
