2 Claims.

5 vide means whereby a press originally designed for printing paper having a specified number of columns may be readily changed for the printing of a paper of a different number of columns without resorting to the necessity of providing a new ink rail.

A further object of the invention is to provide means associated with the ink rail of printing mechanism whereby the inking mechanism may be made to conform to printing or impression mechanism of different widths or involving varied numbers of printed columns, which means may be readily applied to or removed from the inking rail without disturbing or resorting to any material change or alteration of the ink supply mechanism thereof.

With these objects in view, together with others which will appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts all as will be described more fully hereinafter, illustrat ed in the drawing and particularly pointed out in the claims:-

In the drawing: 7

Fig 1 is a fragmentary diagrammatic side elevation of a portion of a conventional newspaper printing machine and showing the application of the invention thereto,

Fig. 2 is an enlarged fragmentary sectional view taken through the ink rail constructed in accordance with the invention, and

Fig. 3 .is a fragmentary plan view of the ink rail.

Referring now to the drawing, and particularly to Fig. 1 thereof, the conventional newspaper printing machine includes an impression cylinder cylinder D, ink distributing rollers E, a first ink cylinder F, an ink pump G and an ink rail H. While the construction illustrated discloses a familiar type of newspaper printing machine, it will be understood that the specific arrangement of the roll train isnot essential to proper operation of the invention, as the invention may be carried out successfully in connection with other types of printing machines.

It will be understood that the ink rail H extends substantially the full width of the ink cylinder F, and carries tubes or ducts Ito deliver ink from the pump G to the throat J. These tubes correspond in number to the columns which the press is designed to print. In instances where it is desired to vary the numberof columns to be printed or to change the widththereof, it has heretofore been necessary to supplya new ink rail to correspond'to the changed widths or numbers of columns of the impression cylinder. As has been heretofore stated, it is the primary purpose of the present invention to dispense with the substitution of an entire new ink rail when conditions such as those mentioned occur.

In carrying out the invention the throat bar J is made separate from the ink rail, and bolts or other securing members K are used in securing the throat bar to the rail. This throat bar, it will be understood, is equipped with ink delivery ports L of a width corresponding to the column width of the paper to be printed, and ink is supplied to these ports by tubes M carried by the throat and detachably connected as by means of unions N to the supply tubes I of the ink rail.

From this construction, it is apparent that when it is desired to change the size or column arrangement of the newspaper, it is but necessary to detach the throat bar J and to substitute therefor a new bar corresponding to the rearranged column design. This change may be readily and expeditiously made without the neces-, sity of special skill or tools; the tubesM, of course, being connected in the manner described to the ink supply tubes carried by the ink rail H.

Having thus described my invention, I claimz 1. .In a printing machine, the combination with an ink cylinder, of an ink rail, ink conveying tubes nested in and supported by the ink rail, a throat bar detachably secured to the ink rail and having an arcuate surface conforming to and cooperating with the periphery of the ink cylinder, means supported by the throat bar for conveying ink to its arcuate surface and the periphery of the ink cylinder, said means being detachably A, a form cylinder B, form rollers C, a second 1nk secured to'the tubes.

2. In a printing machine, the combination with an ink cylinder, of an ink rail, ink conveying tubes supported by the ink rail, a throat bar detachably secured to the ink rail and having an arcuate surface conforming to and cooperating with the periphery of the ink cylinder, tubes extending through the throat bar for conveying ink to the arcuate surface of the throat bar and the periphery of the ink cylinder, and means for detachably securing the tubes of the throat bar to V
