PRINTING-PRESS ATTACHMENT.

Application filed April 10,

To all whom it may concern:

Be it known that T, HENRY BULLrs, a citizen of the United States, and resident of li lilwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Printing- Press Attachments; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention consists in what is herein particularly set forth with reference to the accompanying drawings and pointed out in the claims of this specification as a forcefeed inking attachment for printing-presses; its objectbeing to economize printers-ink, insure an even distribution of the same upon inking-disks of said presses direct from the cans in which said ink is furnished to the trade, and to save time in changing from one to another color of ink.

Figure 1 of the drawings represents a side elevation of ink feeding and distributing mechanism in accordance with my invention partly broken away; Fig. 2, a rear elevation of the same partly in section on the plane indicated by line 2-2 in Figs. 1 and 3; Fig. 8, a horizontal section indicated by line 33 in Figs. 2'and l; Fig. t, a side elevation of a fragment of said mechanism, and Fig. 5, a partly sectional elevation indicated by line 5-5 in Fig. a.

Referring by numerals to the drawings, 6 indicates one of a pair of side brackets attachable to the frame of a printing-press, and rigidly secured in connection with the inner side of said bracket are arms 7 of a support that is shown as being a cylindrical shell 8 open at the rear to permit the placing therein of a can of printers-ink. The can 9 is one inwhichthe ink ..is .,.f i rnished from the manufacturer, and it is set in shell centered on the upper end of a screw-spindle 11 that extends up through an aperture in the bottom of said shell. The plate and spindle together constitute a jack, and a hand-wheel 12 is rigid on the lower end of said spindle to facilitate manual vertical adjustment of the ack. The can-cover 9 is centrally punctured to have slip-fit upon a spout 13 that rises from the center of a preferably conical cap 14:, and this cap set in the can to occupy the sectional area of the same over the contents thereof, the spout being screw-threaded in the top of the shell 8 to discharge upon a disk 15 that Specification of Letters Patent.

turns on a shouldered central boss 16 with which said top of the shell is provided. However the can-top may be omitted without impairing the action of the mechanism herein specified, and it is preferable to employ a packing-disk 1st between the cap 14L and can-contents.

Vithin the shell 8, upon the bottom thereof, is a worm-wheel 17 that is also a nut engaged by the screw-spindle 11 of the aforesaid jack, and engaging said wheel is a worm 18 fast on a spindle 19 for which said shell is provided with a bearing-lug 20. AS a result of an adjustment of the jack in one direction there is a sufficient frictional bind between the. bottom of the can 9 and the j ack-plate 10 to prevent turning of the jackspindle 11 with the worm-wheel 17 that binds in the worm 18 when said spindle is manually operated. Loose on the spindle is the lower fulcrum-end of a lever 21 having a lateral arm 22 provided with a vertically disposed lug 23 in which a stop-screw 2a is adjustable in opposition to the aforesaid shell. Attached to the bearing-lug 20 is one end of a spring 25 and the other end of this spring opposes the lever-arm 22. In pivotal connection with the lever 21 is a pawl 26 that engages a ratchet-wheel 27 fast on the worm-spindle 19, and a spring 28 in connection with said lever opposes lift of the pawl. The lever extends up in the path of a pin 29 depending from the rotary inking disk 30 of the printing-press, and thus provision is had for operating said lever to effect an intermittent elevation of the can 9, whereby there is a force-feed of ink hrough the spout 13 of the cap 1% that is stationary within said can.

To provide for taking up lost motion be tween the worm-wheel 17 and. worm 18, after primary vertical adjustment of the jack aforesaid, a hand-wheel 31 is made fast on the worm-spindle 19, the stop-screw 2 being adjusted to determine the workingthrow of the lever 21.

Loose on a screw 32 depending from the bottom of the shell 8, is a dog 33, also loose on the screw-spindle 11 in the path of the hand-wheel 12, said dog serving to catch the arm 22 of the lever 21 and prevent return of said lever to normal position when the bottom of the ink-can 9 is fed up to the cap 14, whereby the can-lifting mechanism is automatically stopped.

The brackets aforesaid are provided with bearings for a shaft 34: to which guide-bars for spring-controlled shanks of bearings for the ournals of an ink-distributing roller 35 are rigidly secured. One guide-bar 3G, journal-bearing 37, shank 38 and spring 39 are shown, and said bar is provided with an arm 40 attached to a pitman 11 that is utilized in connection with a suitable moving part of the press to effect a reciprocation of the distributing roller 35 upon the disks 15 and aforesaid. It is preferred that each journal of said roller carry an anti-friction wheel stl having travel on the upper trackeclge of the adjacent bracket (3.

Fast on the shaft 3% is a cam 12 opposing a wiper-arm 43 of a lever 1 1 that is fulcrumed 011 the shell 8 and carries a springcontrolled slipping-pawl 15 engageable with a depending ratchet-flange 15 of the disk 15, and a spring 16 connects said lever with an arm 7 of said shell. By means of the mechanism ust described intermittent rotary motion is imparted to the disk 15 to facilitate distribution of ink fed thereto through the spout 13 aforesaid.

From the foregoing it will be understood that the ink is automatically fed at intervals direct from the can 9 to the disk 15, in such quantity as may be determined by the adjustment of the stop-screw 24, and the distributing roller not only spreads said ink on the disk 15 but also carries it onto the main distributing disk 30 of the press where it has further distribution.
