Specification of Letters Patent. P tented Aug. 13, 1918.

Application filed April 20, 1910, Serial No. 556,526. Renewed January 28, 1918. Serial No. 214,254.

To all whom it may concern:

Be it known that I, HENRY A. WISE W001), a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Apparatus for hiking Printing Presses, of which the following is a specification.

This invention relates to an apparatus for inking printing presses.

The principal objects of the invention are to provide for applying ink to the printing press in such a way as to deliver the ink from the fountain in the form of a continuous film of the thickness required for application to the type, so that it will not be necessary to further spread the ink; also to provide for feeding the ink from the fountain mechanism for distributing the ink is provided, much more delicate effects will be secured than heretofore. Further objects of the invention will appear hereinafter.

and the latter of Reference is to be had to ing drawings, in which Figure 1 is a side elevation of a wellknown type of printing press showing how this invention can be applied thereto;

Fig. 2 is a similar View showing how the invention can be used without the usual ink distributingcylinders and rolls. I

Fig. 3 is a plan of the ink fountain.

, tributing rollers, the former of which moves,

continuously or intermittently as the case may be, at an extremely low rate of speed, which must be run at the glue and molasses,

- livering continuously to the ty velocity of the press. This, the invariable form of construction, renders the ductor roller a necessity and as this roller must contact at one time with a slow moving fountain roller and at another with a swiftly moving distributing roller and must repeat these alternative contacts many times a minute upon a fast running press, it will be ob vious that such a roller, which is made of must suffer rapid deterloration.

Furthermore, on newspaper presses, the printing cylinders of which make two hundred turns a minute, which correspond to the production of four hundred papers, itis not practicable to reciprocate the ductor oftener than once for every four revolutions of a printing cylinder, or for the printing of eight papers. This is a notorious defect, as an inking system should be supplied with ink once for each impression, as is done in the case of slow running machines, where the ductor roller can be used effectively without undue wear. It is obvious that if but a single supply of ink is delivered for the printing of eight papers, the first of the eight will receive more than the last, and therefore uniformity cannot exist. This accounts for the fact that the daily newspapers which are run at high speeds are so badly printed.

By this invention I succeed not only in dee an even, continu0us,'and delicately regu atable film of ink, which has neither beginning nor end,

- that press of one of its most troublesome and undurable elements. And in dispensing with the ductor roller I eliminate the last reciprocating element or link in the chain of devices which makes up the rotary press, an element which, because of its reciprocating character, has not only limited the quality of the output of fast presses, but has absolutely prevented the fast press from becom ing a very muchfaster machine,

The present invention also provides for avoiding the necessity of the successivereductions in thickness of the ink, as it is supplied from the fountain in a continuous film of substantially the proper thickness. This film is in the form of a substantially unbroken sheet or stream throughout the inking mechanism, and it is applied in that form to the type. For this purpose the roller is connected directly with the inking mechanism so that it may feed continuously thereto, and the intermittently operating ductor roller for transferring from the fountain to the inking mechanism can be dispensed with as has been stated. In addition to this, the roller is run at the surface speed of the press so that the film received from it will not be necessarily either thickened or thinned in its transfer to the press. The invention also involves the regulation of the thickness of the ink film or sheet as a whole, as it is delivered from the fountain and the variation of the thickness of the different parts thereof, so that the inking of each columncan be regulated separately if desired.

lVith this invention the fountain may be "set directly in contact with the type inking rollers themselves, or rather with the vibrator which is invariably used with said rollers. It can be used, however, with the usual distributing apparatus, and when so used it produces very much more delicate effects than those which can be obtained by the methods heretofore in use.

Referring to the drawings, I have shown the invention as applied to an ink fountain 10 having a fountain roller 11 driven by a gear 12 at the same surface speed as the plate cylinder of the press. In the fountain is a fountain blade 15 to regulate the supply of ink. This blade is in the usual position, but it is made in a number of sections, each being provided with a groove 16 at one edge and atenon at the other, so that the several sections are longitudinally guided by each other. They are also guided between the fountain cover 17 and guides 18 located above the same. Each of these blade sections has secured therein a rod 19. These are provided with set screws 20 for adjusting them individually, so as to regulate the supply of ink at any desired place in the length of the fountain roll They can be adjusted also by these screws to take up wear. for yieldingly pressing them. against the set screws to insure accurate adjustment. One of these ,blades generally is used for each column of printed matter.

The fountain blade as a whole is adjusted to regulate the thickness of the film of ink by moving a transverse wedge bar 23 by means of a hand screw 24 or the like. The wedge surfaces 25 on this bar engage wedge Adjustable springs 21 are provided blocks 26 on the plate 27 which supports the rods and set screws. The hand screw is tapped into the fountain cover as indicated. Springs 28 act against the plate'to keep-the wedges thereon in contact with the wedge bar and insure a nice adjustment. The fountain cover is shown as hinged at 29 so thatv it may be opened taking with it the hand screw, blade, etc. It is held in position by a screw 30 at each end.

. When applied as shown in Fig. 2, a continuous film of ink is delivered from the fountain in an unbroken sheet of uniform thickness to the vibrator 31, from which it is delivered under the same conditions to the type inking rollers 32. The invention can be used with the usual distributing apparatus, however, as shown in Fig. 1. In this case the continuous film is delivered on the vibratory composition roll 33 in an un broken sheet, and is taken from the roll 33 to the form rollers 3 1 in the usual way. I,

- ways in which the invention can be earned out I am aware that many modifications can be made therein by any person skilled in the art without departing from the scope of my invention as expressed in the claims.

Therefore I do not wish to be limited to all the details of construction shown and described, but what I do claim is 1. In an ink fountain, in combination, a fountain roll, a blade therefor formed of separate parts mounted upon a plate, separate means for independently adjusting the separate parts of said blade toward said roll, a separate spring to force each part of said blade away from said roll, additional means to adjust the supporting plate toward the roll, and additional springs to resist said adjustment.

2. In a printing press, the combination with a printing cylinder, of a fountain having a roll, means for driving'the roll at the same surface speed as the vprinting cylinder, means for forming a continuous film of ink upon the roll comprising a blade formed of a plurality of parts, means for adjusting the combination of an ink fountain having a roll therein, a cover pivotally mountedflon the fountain, a support adjustable along the cover toward. the roll, a blade carried by my hand in the presence of two subscribing I said support and consisting of a plurality of wltnesses.

arts, and means carried by said support for 7 H. A. WOOD. mdividnally adjusting the several parts of Witnesses: 5 the blade. 'MABEL M. GLASSEY,
