Application May 3,1956, Serial No. 582,449

1 Claim. (Cl. 101-491),

This invention relates to an adjustable chase and'm-ore particularly to a chase for use in a printing press-for printing one or a very few lines of type slugs onsheets of paper-wherein it is desired to hold the paper in a stationary position and to locate the type l11-Vafi0US places on any particular sheet of paper or groups ofpaper.

In the printing of one or several lines of type on sheets of paper such as pre-printed cards, such as greeting, cards and the like, it is necessary to frequently change the type and it is also necessary to accurately position the type relative to the paper. In the past, locking the type up in a conventional printing press chase has required a great deal of time and moreover, it has been difficult to position the type within the case so that the type prints in the proper location. In many cases, the printed moves the paper so that the paper is in a proper position for printing and keeps the type stationary, changing the position of the paper as the job requires.

Thus, it is an object of this invention to provide a chase wherein the type may be moved into various positions within the case so that the paper upon which the printing is to take place may be held in a single position within the press and the type may be moved within the press for any particular run.

A further object of this invention is to provide a chase wherein the type slug is adjustable within the chase to various positions and moreover, wherein a releasable locking means is provided so that the type slug or several linotype slugs may be quickly inserted into the chase and may be quickly removed simply by pushing the slug into position or by pulling the slug out of position.

These and other objects of my invention will become apparent upon reading the following specification of which the drawings form a part:

Referring to the drawings in which:

Fig. 1 is a top view of an adjustable chase formed in accordance with this invention.

Fig. 2 is a cross-sectional view taken in the direction of arrows 2--2 of Fig. 1.

Fig. 3 is a top view of the slug carrying frame which fits within the chase.

Fig. 4 is a view of a slug of type in an enlargement for illustrative purposes.

The conventional printing press chase consists of a four-sided rectangular frame within which slugs of type are held by means of spacers which are locked into position by various locking means.

In this case, the conventional chase designated as is provided with a pair of guides 12 and 12a, with the guide 12a being positioned more or less against one of the shorter sides of the chase frame and the guide 12 being spaced from the opposite side of the chase frame. The guide 12 is supported by means of a transverse bar 13 within the chase frame with bolts 14 rigidly connected to the guide 12 but slidable through openings 15 in the transverse bar 13 and springs 16 which resiliently urge the guide 12 towards the center of the chase frame.

A third, slu'g' holding, frame '30' is arranged between.

The slug frame 30 holds a type slug 32 in position for printing with the type faces 33 of the type extending above the fiat frame planes as indicated in Fig. 2.

In order to releasably hold the type slug in position, a locking bar 35 is provided within the slug frame, spaced from the slug frame side 34, with the locking bar 35 being spring urged toward the side 34 by means of springs 36 surrounding bolt 37. Here again, the bolts 37 are rigidly connected to the locking bar 35 but pass through openings 38 in the side opposite the locking bar side of the slug frame. Fig. 3, illustrates this construction,

per se.

It can be seen that with this type of construction, and particularly with reference to Fig. 1, that the slug frame can be moved to the left or right and will be held in position by means of a fiat presser bar pressing the slug frame against the opposite side of the second frame. Likewise, the second frame can be moved upwards and downwards against the resistance of the spring biased guide 12 for positioning the type in an upward or downward position.

Moreover, the slug is normally considerably shorter than the length of the slug frame so that it also can be moved within the slug frame for adjustment where necessary, although normally, the slug is pushed tightly against the left side of the slug frame as indicated in Fig. 1.

In order to accurately position the type slug, indicia are provided on the guide 12a, which indicia 40 indicates the position of the second frame. For example, the top of the second frame can be used relative to the indicia. For the same purpose, indicia 41 are provided on the presser bar 22 so as to accurately locate the slug frame in its movement relative to the presser bar. Again, the extreme left side of the slug frame could be used as a point for measuring the location along the indicia 41.

It can be seen that this construction utilizes the ordinary chase frame found on the printing presses but by the insertion of the second and third slug frame and by means of the spring biased guide and presser bar, the interior frames can be moved so that the type slug can be adjusted upward and downward or left and right as seen in Fig. 1.

It is apparent, that the spring biasing means used for each of the frames could be modified in several ways such as, for example, by the provision of blocks of rubber or other types of resilient urging means such as a leaf spring or the like. It is important only that the resilient urging means be of sufi'icient strength to lock the frames into position normally and yet be yieldable enough so that the frames can be moved when sufiicient force is applied to slide them between their respective guides as shown.

This invention may be-further developed within the scope of the following claims and accordingly it is desired that the foregoing description be read as being merely illustrative of an operative embodiment of this invention and not in a strictly limiting sense.

Having fully described an operative embodiment of my invention, I now claim:

An adjustable chase for use in adjustably positioning a slug of type in various positions for printing, comprising a first rectangular shaped open frame having parallel spaced guides formed within the frame; spring means and a presser bar between one side of the frame and one guide for bearing it towards the other guide; a second rectangular shaped frame positioned within the first frame and fitting between the guides and being considerably narrower in dimension in the direction parallel to the guides for relative sliding movement within the first frame; and a third rectangular frame fitted within the second frame and being so dimensioned as to be freely slidable in the second frame in a direction transverse to the guides; spring means and a presser bar between one side of the second frame and the third frame for biasing the latter towards the other side of the second frame; and releaseable locking means in the third frame for holding a. type slug whereby said slug may be moved parallel to or normal to the guides and may be releasably secured in position within the third frame, said releasable locking means in the third frame comprising a spring means, and a presser bar between the slug and one side of the third frame for biasing the slug against the other side of the third frame.
