March 17, 1936. c. RECKEWEG PRINTING FURNITURE Filed Sept. 9, 1955 CHARLES EfC/(fWfG Patented Mar. 17, 1936 UNITED STATES FATE 1' The present invention relates to printing furniture particularly adapted for use in looking up type arranged in any suitable manner in a chase, for use on cylinder and vertical presses.

5 In the printing industry to-day, the majority of type is set by machine and cast into oblong slugs or type bars. After the casting operation has been completed, the slugs, as they are termed, are automatically trimmed on the edges. During the trimming operation, if the knives become dull or are dull, the edges of the slugs are rough and uneven, then too the edges of the slugs are not always trimmed true, consequently when a number of these slugs are set up in forms, an 15 uneven surface appears. Due to the irregular surfaces or edges, the furniture as used to-day in the trade will not hold the type on its feet when locked up in the chase. Stripping has been resorted to in an endeavor to prevent work-ups 20 which consume a great deal of time of the pressman, and to some extent the stripping assists in holding the type on its feet, but even with the stripping there is the uncertainty of registering. Stripping the form as applied to the trade is the placing of a narrow strip of paper or cardboard about a quarter of an inch high around the form and between the present day furniture.

Actual experiments conducted by me in the trade have proven, that the only possible way that type can be securely held on its feet and work-ups eliminated, as well as eliminating the time required to strip a type form, is the form of furniture herewith illustrated, described and claimed.

One of the primary objects of my invention is the provision of novel printing furniture that will impinge type forms at their lowermost por-' tions, thereby keeping the type on its feet.

Another object of my invention is the provision of novel printing furniture that when locked in a chase with type forms, will securely hold the type on its feet, and on the bed of the press.

A further object of my invention is the pro-vi- 45 sion of novel printing furniture that eliminates work-ups.

A still further object of my invention is the provision of novel printing furniture that eliminates stripping the forms.

A still further object of my invention is the provision of novel printing furniture that assists in eliminating slurring and wrinkling during the printing operation.

A still further object of my invention is the provision of novel printing furniture that assists in disposing of air trapped between the paper ically described, claimed and illustrated in the accompanying drawing, in which drawing:

Figure 1 is a perspective View of my novel printing furniture. Figure 2 is an end elevational view of same. Figure 3 is a perspective View of a chase, a type form in the chase surrounded by my novel furniture and locked therein.

Figure 4.- is a transverse sectional view taken on line 4-4 of Figure 3.

The numeral 5 represents a chase of the type 'used in the printing trade. Within the inner confines of the chase 5 is a type form 6, which as illustrated in Figure 3 of the drawing is sur-- rounded by pieces of my novel furniture 1. The ftuniture l as illustrated per se in Figures 1 and 2 of the drawing may be of any suitable length, width and thickness, and in the present showing I have illustrated the furniture as chase high. The furniture is provided with a rabbet 8 on each longitudinal edge and it is cut to a depth of approximately one-half of the total height of the furniture. If furniture is used thicker than chase high, the portion of the furniture represented by the numeral It} remains the same height. The width of the rabbet 8 as illustrated by the numeral 9 is of a width known in the trade as three point, or approximately five-sixteenths of an inch. By this construction, the lower portion of the furniture at H] is wider than the upper portion l I.

In Figures 3 and 4 of the drawing it can be seen, that due to the furniture having a rabbet 8 on both longitudinal edges, one of the edges l impinge the type form, the upper portion of the furniture being of a reduced width due to the rabbet 8, the portion 9 of the furniture forms a space or channel way I2 around the type form. During the printing operation, accumulated air and static pressure passes into these channel ways, thereby assisting in eliminating slurring and wrinkling of paper being printed.

Interposed between the inner side edge of the chase and my novel furniture 1 are quoins l3 and I4, each of which comprise two members l5, I6, I! and I8. The members l5, l6, l1 and I8 are each provided with a rib l9 and a groove 20, the rib of each member engaging the groove of each member. The quoins l3 and i4 clamp the sides of the forms and hold them against transverse movement.

If desired, a bar 2| may be inserted at one end of the chase and quoins- 22 and 23, identical in structure to quoins l3 and I4 may be interposed between the bar 2| and the furniture I. The quoins 22 and 23 in conjunction with the furniture, clamp the opposite ends of the form and hold it against transverse movement.

As illustrated in the transverse sectional view Figure 4 of the drawing, it can be seen that the side wall l0 of the furniture being restricted as to highth, the restricted portion grips the type form at its lowermost portion, thereby holding the form rigid, and thus preventing the type from working up, and further this restricted highth of the. side wall eliminates the stripping of the form prior to the lock-up in the chase.

While the principles of the invention will always be adhered to, the invention is susceptible to certain changes and modifications and. I do not wish to limit myself to the exact structure and changes may be made without departing from the spirit or scope of the invention.

What I claim is:

1. Furniture for printing comprising a bar, a rabbet in each longitudinal side wall of said bar, the lower portion of said bar being of a greater width than the upper portion.

2. Printing furniture comprising a bar, a rabbet in each longitudinal side wall of said bar, the lower portion of said bar being of greater width than the upper portion, said rabbet providing an offset in each longitudinal side wall of said bar.

3. Printing furniture comprising a bar, a rabbet in each longitudinal side wall of said bar, the lower portion of said bar being of a greater width than the upper portion, the lower edges of the side walls of the lower portion of said bar being uniplanar with the bottom face of said bar.

4. In combination, a chase, type forms surrounded by furniture in the chase, said furniture provided with a rabbet in each longitudinal side wall, the lower portion of said furniture being of a greater width than the upper portion and a channel way around said type forms.

5. In combination, a chase, type forms surrounded by furniture in the chase, said furniture provided with a rabbet in each longitudinal side wall, the lower portion of said furniture being of a greater width than the upper portion, the inner side walls of the lower portion of said furniture impinging the lower portions of said type forms and a channel way around said type forms.

6. In combination, a chase, type forms surrounded by furniture in the chase, said furniture provided with a rabbet in each longitudinal side wall, the lower portion of said furniture being of a greater width than the upper portion, the inner side walls of the lower portion of said furniture impinging the lower portions of said type forms, a channel way around said type forms, said type forms and furniture locked in said chase by quoins.

7. In combination, a chase, type forms surrounded by printing furniture, said furniture provided with a rabbet in each longitudinal side wall, the lower portion of said furniture being of a greater width than the upper portion, the inner side walls of the lower portion of said furniture impinging the lower portions of said type forms,

the lower edges of the side walls of the lower por- 1 tions of said furniture being uniplanar with the bottom faces of said furniture, a channel way around said type forms, said forms-and furniture locked in said chase by quoins.
