ATTACHMENT FOR PRESSES.

Specification of Letters Patent.

Patented Aug. 28, 1917.

Application filed May 26, 1917. Serial No. 171,307.

T 0 all whom it may concern:

Be it known thatI, IVILLIAM S. Jonas, a citizen of the United States, and resident of Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Attachment for Presses, of which the following is a specification.

My invention relates to attachments for presses whereby the date line or the like may be quickly and easily changed.

More particularly it is my object to provide an attachment for presses comprising a multiple part bar, one of the parts of said bar having a member adapted to receive a slug carrying the date line or the like, the parts being so constructed and arranged that one of the parts may be readily and easily removed for changing the date line slug.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 shows a perspective view of my improved attachment for presses.

Fig. 2 shows a transverse, sectional view of the same, taken on the line 22 of Fig. 1.

Fig. 3 shows a top or plan view of the same installed on the press, and

4 shows a vertical, central, sectional view through said attachment.

Before describing my improved attachment, I will briefly describe the problem which I desire to solve by my invention. On large cylinder or rotary presses there are ordinarily used two forms or plates, each covering half of the press. The press or forms are provided with some means for holding the metal slug, on the outer face of which are formed characters indicating for -instance, the date and page of the sheet of newspaper or the like. In printing newspapers, it sometimes occurs that an edition is printed in which it is desired to quickly change the date line. With the ordinary equipment now in use. it is necessary to remove the entire form in order to change the date line. This involves the expenditure of considerable time, which is a very important item in a newspaper office. My device is so constructed and arranged that the date line can be changed Without removing the forms from the press, and can be quickly and easily done.

In the accompanying drawings I have used the reference numeral 10 to indicate generally the press bed of a large cylinder press. Mounted on the press bed are the forms 11 and 12, each arranged to cover substantially half the press circumference. Between the adjacent edges of the forms 11 and 12 I have mounted my improved attachment, comprising what might be called a multiple part bar. A portion 13 of the bar is fixed to the press bed between the adjacent edges of the forms by means of screws 14, shown in Fig. 1. Arranged in alinement with the bar member 13 is a movable member 15. The edge of the bar 13 adjacent to the movable member 15 is beveled from its outer surface at 16, downwardly and away from the movable member 15. The bar 13 is also provided with a tongue 17 projecting toward the member 15 and having its edge ad j acent to the member 15 beveled at 18 in a manner similar to that of the beveled edge 16.

Thebar 15 is provided at its end adjacent to the bar 13 with a beveled edge 19 adapted to engage the beveled edge 16, and with a slot or groove 20 adapted to snugly receive the tongue 17 and to fit the beveled edge thereof. The bar 15 is provided in its upper surface with an opening 21 to receive a tool for moving or handling the bar 15 when it is placed in position snugly received between two forms.

The bar 15 is provided at one side edge with a removable bar 22 mounted on the main body of the bar 15 by means of screws 23 or the like, and provided in its central portion adjacent to the bar 15 with a slot 24 extending through the member 22 and adapted to receive the slug 25 on which the date line or the like is formed. The ends of the slot 24 are inclined or beveled at 26, as shown in Fig. 4, to fit the beveled ends 27 of the slug.

It will be seen that the slug should be inserted into the slot 24 from below, and that on account of its beveled ends and the beveled ends of the slot 24, the slug will rest against the press bed and can be moved outwardly. One end of the movable bar 14 extends beyond the member 22 and is bifurcated andformed with spaced opposite arms 28.,

Mounted in the press bed is a screw 29 which extends upwardly through the slot or space between the arms 28 when the device is installed in position.

In the practical use of my improved attachment, the srrew 29 is loosened, the slug 25 is inserted into the slot 24: from below, the arms 28 are slipped under the head of the screw 29, and the bar is laid against the press bed and then slid longitudinally toward the bar 15 until it reaches its locked position, whereupon the screw 29 is screwed inwardly for locking the attachment in position for use.

In this connection it may be mentioned that the thickness of the arms 28, combined with the thickness of the head of the screw 29, is such that when the parts are installed the screw 29 will not project outwardly to be in the way.

lVhen it is desired to change the date line, the screw 29 is loosened, the bar 15 is slid longitudinally away from the bar 13, the end of the bar 15 adjacent to the end of the bar 13 is then raised and the bar 15 is slid longitudinally in the opposite direction. The date line slug may then be removed and another date line slug inserted in its place. The movable member 15 may then be locked in position for use.

The advantages of an attachment of this kind may be largely seen from the foregoing description. The device is of comparatively simple construction and may be quickly and easily operated for changing a date line or the like without removing the forms from the press.

It will be noted that the movable bar member 15 when installed in position, is thoroughly locked against movement in any direction.

Some changes may be made in the construction and arrangement of the various parts of my improved device without departing from the essential features and purposes of my invention, and it is my intention to cover by the patent to be issued upon my application, any modified forms of structure or use of mechanical equivalents which may be reasonably included within the scope of the claims of said patent.

I claim as my invention:

1. An attachment for presses comprising a bar member, a movable bar member, said bar members having ends adapted to interlock with each other, said movable bar mcmher having a slot extended through it, provided with beveled ends and having an end extending beyond said slot, formed with. spaced arms, and a screw designed to be mounted in a press bed and extended between said arms, having a head adapted to be above said arms.

2. In a device of the class described, a bar member having a projecting tongue, said tongue and the portions of the end of said bar member adjacent thereto being beveled, a movable bar member having one end provided with a groove, said end and part of said groove being beveled to fit the beveled end of said first bar and said tongue, said movable bar having formed therein a slot formed with beveled edges to lit the beveled edges of a slug, said movable bar member being formed with an end project ing beyond said slot, having spaced opposite arms, and a screw designed to be mounted in a press bed and to extend between said arms, said screw having a head adapted to engage the outer surfaces of said arms for holding said movable bar member against the press bed.
