JESSEY F. HARRELL, OF INDIANAPOLIS, INDIANA.

PRINTING-INK DISTRIBUTER.

Application filed June 21, 1913.

To all "whom it may concern:

Be it known that I, JESSEY F. HARRELL, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Printing-Ink Distributer, of which the following is a specification, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon.

This invention relates to the type of print ing press commonly known as a jobbing press, such as the well known Gordon press in which type the printing ink is distributed on a disk and taken therefrom by the rollers that ink the type forms, the invention having reference more particularly to a press of the above mentioned character that is provided with an ink font for automatically supplying the ink to the rollers and more or less imperfectly distributed by the rollers on the disk.

The object of the invention is to provide an automatic ink distributer for printing presses of the above mentioned type that will be adapted to take the ink from the feed roll of the font and partially distribute the ink on the disk or plate to be further distributed as usual by the ink roller, a further object of the invention being to provide an improved ink distributer that shall be so constructed as to be adapted to be readily applied to the printing presses now in use, all to the end that the most perfect distribution of the printing ink may be obtained in an economical and efficient manner in order that superior printing may be produced.

A still further object of the invention is to provide an ink distributer of such construction as to be adapted to control the feeding of the ink so that the feeding may be momentarily discontinued when no printing impressions are being made during the movement of the press.

With the above mentioned and other objects in view, the invention consists in novel printing ink distributing appliances and in novel means for mounting the appliances on an ink font, and the invention consists further in the novel parts and in the combinations and arrangements of parts as hereinafter particularly described and claimed.

Referring to the drawings, Figure 1 is a perspective view of a job printing press provided with the improved ink distributer; Fig. 2, a fragmentary perspective view with Specification of Letters Patent.

Similar reference characters in the diflerent figures of the drawings indicate corresponding elements or features of construction herein referred to.

For the purpose of illustrating the invention and describing the construction and,

function thereof reference is had to a well known type of ob printing press which comprises a main frame 1, on which a shaft 2 is rotatably mounted and suitably driven by means of a gear wheel 3 fixed to the shaft, a disk 4 being secured also on the shaft.

The main frame supports the tilting platen 5, as will be understood, and a movable frame 6 is pivoted to the main frame and has the type bed 7 on which the type forms are placed. The movable frame has a pivot rod 8 to which rods 9 and 9' are connected, the rods being connected also with crank pins on the disk 4: and wheel 3 respectively, as will be understood, so that on rotation of the shaft 2 the movable frame is moved toward or from the main frame. The pivot rod 8 has an eccentric sleeve 10 thereon that is provided with a controlling arm 11 to which a rod 12 is connected, the rod being connected also to an arm 13 fixed on the shaft 1 1 which is provided with an operating arm 15, to which a rod 16 is connected, the shaft 14 being mounted in the main frame, and the hand lever 17 is mounted also on the main frame and connected to the rod 16, whereby the eccentric sleeve which is connected with the movable frame may be moved for changing the axis of the rod 8 for preventing the contact of the type form with the platen. A suitable inking plate or disk 18 is mounted on the movable frame and suitably rotated periodically, two concentrically arranged plates commonly being employed. Aroller frame 19 is mounted to rock on the pivot rod 8 and is provided with a wrist-pin 20 to which a rod 21 is connected, the rod being connected also to a pivot 22 supported by the main frame, for causing the roller frame to rock.

A suitable number of inking rollers 23, 24, and 25, are suitably mounted on the roller frame whereby they are guided over the inking plate and the type form. A suitable ink font 26 having ends 27 and 28 is suitably mounted on the movable frame rearward of the ink plate or disk and has a feed roll 29 therein, the roll having a journal shaft 30 on which is a ratchet-wheel 31 and also an arm 32 that is movable on the journal shaft and has a dog 33 thereon in contact with the ratchet-wheel. A rod 34 is connected to the arm 32 and also to a yoke 35 that is secured to the roller frame, whereby the feed roll is caused to move periodically for feeding the ink from the font.

The construction and mode of operation of the press being well known require no further description in detail.

In order to conveniently mount the improved ink distributer on the particular type of press and ink font described, a pair of standards 36 and 37 are provided which have toes 38 and 39 and heels 40 and 41, respectively adapted to fit upon the ends 27 and 28 of the font to which the toes are secured by means of screw- bolts 42 and 42 respectively, the heels being held in place by means of dowels 43 and 43 A rock-shaft 44 is mounted on the standards and has a rocker-arm 45 secured thereto. A pivot head 46 is secured to the rod 21 preferably by means of a set-screw 47 and is provided with a pivot 48 to which a rod 49 is connected, the rod being connected-also to the rocker arm 45. Two arms 50 and 51 are secured to the rock-shaft 44 and two frame bars 52 and 53 are pivotally connected at their ends to the ends of the arms respectively and carry a suitable distributing roller 54. Two guides 55 and 56 are formed on the arms 50 and 51 respectively adjacent to the rock-shaft. Two controlling bars 57 and 58 are pivotally connected to the frame bars 52 and 53 respectively and are provided with guide rods 59 and 60 that extend movably through the guides 55 and 56 respectively. Two coil springs 61 and 62 are placed on the guide rods and seated upon the bars 57 and 58 respectively and in contact with the guides 55 and 56 respectively. The guide rods 59 and 60 are provided with stop collars 63 and 64 adapted to have contact with the opposite or upper sides of the guides 55 and 56 for suspending the distributing roller and are moved away from the guides during compression of the springs. A frame bar 65 is connected to the bars 52 and 53 and preferably serves as a pivot for the bars 57 and '58, a link 66 being connected to the bar 65 and also to one arm 67 of a bell crank havillustrated in Fig. 5.

ing another arm 68, the bell crank being r0- tatably mounted on the rock-shaft 44. A pull-rod 69 is connected to the arm 68 and has a longitudinal slot 70 therein. A bracket 71 is suitably mounted on the back of the ink font 26 and preferably has a lip 72 that hooks over the top of the font, the bracket being otherwise secured to the font as may be preferred and it is provided with a pivot 73 on which a bell crank is mounted that comprises an arm 74 provided with a wrist-pin or pivot 75 that extends through the slot 70 and may be moved into contact with the end of the slot, the bell crank having another arm 76 to which a rod 77 is connected. A strap 78 having cars 79 is fixedly secured by means of a bolt 80, placed in the ears, to the eccentric sleeve 10, the strap being provided with a pivot 81 to which the rod 77 is connected. It should be understood, however, that the pivot 81 may be otherwise mounted on the eccentric sleeve 10 so as to be carried about the pivot rod 8 during the usual operation of the press as struction may fairly be made within the scope of the appended claims.

In practical use the rod 21 moves up and down about the pivot 22 while the movable frame 6 moves to and fro and carries the inking and distributing apparatus, so that the rocker arm 45 is caused to move to the different positions indicated in the various figures of the drawings. WVhen the inking rollers are in the posit-ion indicated in Figs. 2 and 3 the distributing roller 54 is taking ink from the feed roll 29, and as the inking rollers move forward over the distributing plate 18 the distributing roller 54 is moved behind them also on the plate and distributes thereon the ink it may have received. WVhile the inking rollers are passing over the type form the roller 54 distributes the ink and is carried off from the lower portion of the inking plate 18 during the time the ink plate is rotated, this position being ment occurs in advance of the movement of the inking rollers upward from the type form to the distributing plate. In case it is desired that an impression shall not be made by the type form the operator moves the lever 17 which prevents full forward movement of the bed of the press, as will be understood and at the same time the rod 77 is pulled down and moves the pin 75 to the end of the slot 7 O, and through the pull- The reverse move-- rod 69 moves the connections so that the distributing roller 54: is drawn forward slightly as shown in dotted lines in Fig. 3 to prevent contact thereof with the feed roll 29, so that no ink is taken up until normal operation of the press is resumed.
