LATE-N EWS-PRIN TING DEVICE.

Application filed September 3, 1921. Serial No. 498,375.

To all whom it may concern Be it known that I, EDWARD P. SHELDON,

a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Late-News-Printing Devices, fully described and represented in the following specification and the accompanying drawings, forming a part of the Same.

This invention relates to certain improvements in printing machines.

In printing newspapers or'the like it is frequently desirable to print what is generally termed in the art late news, this late news being printed on a web or sheet which has already been printed with certain matter forming the main body of the news, suitable space being left unprinted on the web to receive this late news. In printing this late news, only a comparatively small amount of matter is printed whether the columns run with or across the web and consequently the late news printer is in printing relation with the web but a short period of time, being in printing relation only when the sheet which is to receive the late news is being printed upon. Furthermore when a product of several successive sheets, only one of which is to carry late news, or when collecting, the late news printer must be out of printing re lation while the sheets or portions of the web not to be printed upon are passing the printer.

It is the especial object of the present invention to produce an attachment for printing machines for printing late news which shall be so constructed and arranged in a printing machine in relation to an impression member that the late news printer shall be held normally out of printing relation, and thrown into printing relation and held in such printing relation only when it is desired to print.

A further object of the invention is to provide such an attachment which shall be easy of access so as to make the placing of late news forms in position easy and quick, which shall be easily and quickly adjustable so as to print on any portion of the web or sheet where such printing may be desired, and which can be permanently thrown out of action when no late news is to be printed in a pfirticular product running through the ma- 0 me.

lVith these and other objects not specifically referred to ill view, the invention consists in certain novel parts and constructions, a preferred form of which is shown in the drawings, and which will be fully described in connection with such drawings, and the novel features then pointed out in the claims hereunto annexed.

In the drawings:

Figure 1 is a side elevation, partly broken away and partly in section, illustrating so much of the printing machine as is necessary for an understanding of the invention;

Figure 2 is an end view on a somewhat enlarged scale of the parts shown in Fig. 1; and

Figure 3 is a detail, partly sectional, plan view illustrating certain driving mechanism for actuating the late news printer.

Referring now to the drawings, 1 indicates the side frames of a printing machine which may be of any usual or suitable construction for supporting the parts hereinafter referred to, these side frames rising from a suitable base, not illustrated.

Mounted in these side frames is the impression member of a printing couple, the form member not being illustrated, this impression member in the particular instance shown being a cylinder 2 mounted on a shaft 3 journalled in the frames of the machine, this shaft being driven from a gear 4 fast to one end thereof and operated from any suitable moving part of the machine. The web W is shown as passing over this impression cylinder, the main portion indicated at 5 having been printed, with a space indicated at 6 left unprinted for the reception of the late news.

In accordance with the invention, a late news printer is provided for printing in the unprinted portions of the web. lVhile this late news printer may take various forms it will be of such character that an intermlttent printing relation between the late news printer will be established in an automatic manner so that only the blank space in the web will be printed. Furthermore this PI'lIlter. will be so constructed and arranged that printing relation can be established at any desired point on the cylinder, and a preferred construction for effecting this is illustrated.

As shown the late printer consists of a small cylinder 7 carrying the late news forms, illustrated at 8 This cylinder is mounted on a shaft 9 extending across the machine and journalled in the side frames before referred to. The shaft 9 is provided at each end with a gear 10 fast on the shaft, and this gear in turn is in mesh (see Figure 3) with one of a pair of gears 11, 12 secured together on a common hub 13 and loosely mounted upon a stud 15 eccentrically mounted in one of the side frames of the machine, this construction being duplicated at each side. The other gear 12 meshes with a gear 16 on a hub 17 on which hub is also carried a cam 18, this gear 16 and the cam 18 with the hub being loosely mounted on the shaft 9 before referred to. In the particular con- Y struction illustrated these gears are so proportioned as to give the cam one full turn to half a turn of the impression cylinder 2, so that in the particular construction shown the printer will print on each succeeding sheet.

The shaft 9 is mounted in journal boxes 19 which have a slight movement in the frames 1, these journals being seated on springs 20 suitably "secured in the frame so that the springs bear directly on the journal boxes and act to normally hold the printing cylinder out of printing relation with the impression cylinder 2, this arrangement being preferably adapted for securing the nonprinting relation of the late news printer and the impression cylinder.

To efi'ect printing relation of the parts automatically at the times desired there is 7 provided an abutment in the form of a roll 21 carried in brackets 22 in the side frames of the machine, this roll being fixedly journalled and lying in the path of the cams. When the low part of the cam is hearing on the roll the parts are held separatedin non-printing position through the medium When, however, the high part of the cam runs into contact with the roll the printer shaft is forced downwardly against the springs and the printing relation established between the printer and its cooperating impression cylinder, the cam, of

course, being formed to cause this printing contact to be maintained long enough to effect the printing desired. The frequency with which this relation is thus automatically established depends on the pro ortion of the gearin which determines t e frequency with w ich the high part of the cam comes in contact with its cooperating roll.

In the late printers construction of the best form and so that a small printing cylinder may be used for the late news pr nting, this cylinder and its inking mechamsm' will be so mounted in the machine that the printer can be moved across the impression cylinder and eflect ,a printingat any desired part of the web widthwise.

While various constructions may be employed for efi'ecting this, in the particular construction illustrated, there are provided a pair of rods 22, 23 extending across the machine and supported in the side frames 1 before referred to. These rods slidably support a pair of brackets 24, 25 in which are mounted the ink fountain 26, ductor 27 and distributing rolls 28, 29, 30, for inking the forms on the printing cylinder, and the printing cylinder itself is ,slidably mounted on the shaft 9 so as to be movable lengthwise thereon.v The inking rolls may be driven in any suitable'manner as from a gear 31 slidable on the shaft 9 which meshes with a gear 32 on a shaft 33 carried on the brackets 24, 25 before referred to, the ear 32 engaging with the gear 34 on the s aft of the inking roll 28.

While but one printer is shown and described, it will be understood that, particularly with wide cylinders, where it is desired to simultaneously print at a plurality of places across the web, any desired number of printers and inking mechanisms may be provided.

The shaft 9 carrying the printing cylinder may be driven in any suitable manner. In the particular construction illustrated, there is provided a gear 35 slidingly secured on the end of the shaft as by a key 36, this gear 35 meshing with the gear 4 on the impression cylinder shaft 3 before referred to. By slipping this gear 35 out of mesh with the gear 4, the printer may be permanently put out of action. In some circumstances it may be desirable to stop the printer without disconnecting these gears and this may be very simply accomplished by throwing the gears 11, 12 out of mesh with the gears 10 and 16 by which cam 8 is driven, the cam being thus silenced and the operation of the printer stopped. Various means may be employed for effecting the disengagement of these gears. In the particular construction illustrated the eccentric stud 15 before referred to is provided with an arm 37 in which is formed a slot 38 taking over a stud 39 suitably mounted in the frame, the arm being held in position on the stud by means of a lock nut 40. The arm 37 is extended beyond the grooved portion to form an operating handle 41 by which the arm may be rocked and through the eccentricity of the stud the gears disengaged.

With "the construction shown and 'deprinter has been provided, one which may scribed a very simple and efl'ective late news 7 be readily installed in an old as well as a i new machine, one which is quick and eas of access for securing late news forms in p ace, and one which may be-used on any part of a web.

various changes may be made in the specific members of the gearing out 0 tions for driving construction and arrangement of the parts without departing from the invention, and that suitable gearing may be employed to permit printing on any page or sheet of the web desired, and that the invention is not to be limited to the gears proportioned as described.
