WALLACE S. WARNOCK, OF CHICAGO, ILLINOIS.

PRINTERS FILLER-BLOCK.

To all whom it may concern:

Be it known that I, WVALLACE S. WVAR- 'NOCK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Printers Filler- Blocks, of which the following is a full, clear, concise, and exact description, reference being had to the accompanylng drawings, forming a part of this specification.

My invention relates to printers furniture and more particularly to rinters filler blocks that are used in comp eting and setting up printers forms by occupying spaces therei I will explain my invention fully by reference to the accompanying drawing, showing the referred embodiment thereof, in which Figure 1 is a perspective View showing one size of a filler made in accordance with the invention. Fig. 2 is a sectional View on line 2 2 of Fig. 1. Fig. 3 is a sectional view on line 3 3 of Fig. 1. Fig. 4 is a plan view showing an initially constructed blank that is adapted to be formed into the product shown in Fig. 1. Fig. 5 indicates the blank shown in Fig. 4 after the second step in the construction of the roduct has been taken. Fig. 6 is a sectional view on line 6 6 of Fig. 5. Fig. 7 is a sectional view on line 7 7 of Fig. 5.

Like parts are indicated by similar characters of reference throughout the different figures.

As hitherto stated, Figs. 4 and 5 indicate the first and second steps that are taken to produce the product illustrated in Fig. 1, the third ste resulting in substantially the product il ustrated in Fig. 1, a final 1press operation being employed to finish t e joints between the sides of the filler, as will appear.

In practicing my invention I form the blanks shown in Fig. 1 out of a sheet or strip of metal, preferably sheet steel, the contour of the blank being clearly indicated in Fig. 4, the dotted lines in Fig. 4 indicating aproximately the lines along which the metal 18 folded in subsequent operations. After the result of the first stamping operation indicated in Fig. 4 has been secured, the resulting blank is subjected to a second stamping 0 eration, whereby the blank is folded into t e shape shown in Fig. 5 and in full lines in Figs. 6 and 7. The blank is then subject to a third stamping operation, whereby it is folded into the shape shown in Figs.

1, 2 and 3. As a result of these three stamping operations, a structure is produced which comprises a diaphragm a and side walls I) and c integrally formed with the diaphragm, each wall of the filler projecting from the diaphragm first in one direction and then by being returned upon itself, in the other direction, the walls being integrally continued out of the metal forming the diaphragm.

The diaphragm acts as an effective brace to substantially maintain the walls of the filler in their proper relative positions with respect to each other, the diaphragm resisting compressive action upon the filler and distending action also, so that the filler is neither liable to collapse or buckle. To this end, the diaphragm lies in a plane between and parallel to the planes of the top and bottom of the filler, while the adjacent portions of each folded wall lie close together in order that the diaphragm may act as a compression member between the outer folded portions of the walls. The outer marginal portions of each side of the filler lie in a common vertical plane so that the filler may be properly engaged and clamped in place. The stamping operation is .such that the diaphragm and the portions of the walls of the filler immediately rising or projecting therefrom constitute a cup or dish whose bottom and walls are free of dividing cuts, as will be most apparent by reference to Fig. 5, where one of the corners is shown in section at d. All of the corner portions are similar to the corner portion (Z, the sides of the dish mentioned being integrally continuous with respect to each other as well as with the diaphragm. The dish construction mentioned is formed in the second stamping operation, whereafter, in the third stamping operation, the sides of the filler shown as projecting at right angles to the sides of the dish in Figs. 5, 6 and 7, are bent downwardly as indicated by the dotted lines in Figs. 6 and 7 and as shown in Figs. 1, 2 and 3.

In Fig. 4 the lines f indicate the lines along which andat which the sides of the filler are bent downwardly.

In order absolutely to fix the meeting edges of the sides of the printers filler block with respect to each other, I desirably provide some of the sides with tongues g and the remaining sides with grooves h adapted to receive said tongues, these tongues being located at the meeting edges of the sides of the are of a size snugly to be received within the recesses h, and by reason of the slightly increased length of the tongues over the thickness of the metal, these tongues may be upset or compressed by the fourth and last stamping operation, whereby they are expanded into forcible and very firm engagement with the metal of the filler at h.

If desired, the corner portions of the filler may be put through a finishing process to remove any slight projections that the tongues might still afford. The outer edges of each side of the filler lie in a common vertical plane, so that the sides of the filler may be snugly engaged by other furniture or parts in a printers form. Thus the sides of the filler block are jointed together at the corner portions of the filler block, thereby to insure the maintenance of the meeting edges of the side portions of the filler in fixed re ative positions. The retaining joints are provided in the outside portions of the walls and are not needed elsewhere because the corner portions of the inner parts of the side Walls are integrally formed. By this latter construction the rigidity of the filler is very materially increased.

It will be seen that I have produced a filler comprising a frame formed of strip or sheet metal having jointed meeting edges and a diaphragm inclosed by the frame and integrally formed therewith. I/Vhile I prefer the use of the oints at gand h, I do not wish to be limited to the employment thereof in the product of my invention.

It will be seen that an important advantage gained by my construction resides in the fold in' each side of the filler, whereby the strength of the sides of the filler is greatly enhanced, particularly if the inner portions of the folded sides are continuously integral.

I use the term printers filler block in the sense of a block which is rectangular in plan view and each of whose sides is vertical and is adapted to be clampingly engaged in a printers form to fill spaces within the form.

While I have herein shown and particu larly described the preferred embodiment of my invention, I do not wish to be limited to the precise construction shown, as modifications may readily be made in the embodiment of the invention shown without departing from the spirit of my invention, but,

Having thus described my invention, I

These tongues 2. A printer's filler block including a frame having sides formed of sheet or strip metal folded on lines extending longitudinally of said sides, and a diaphragm uniting inner parts of said sides, said sides and diaphragm being integrally formed out of the same piece of metal. T

3. A printers filler block including a frame having sides formed of sheet or strip metal folded on lines extending longitudinally of said sides, and a diaphragm uniting inner parts of said sides, the outer parts of said sides having jointed meeting edges.

5. A printers filler block including aframe having sides formed of sheet or strip metal folded on lines extending longitudinally of I said sides, adjacent corner portions of inner parts of said sides of the frame being integral.

6. A printers filler block including a frame having sides formed of sheet or strip metal folded on lines extending longitudinally of said sides, and a diaphragm in union with the inner parts of said sides, said diaphragm lying in a plane between the top and bottom of the filler.

7. A printers filler block including a frame having sides formed of sheet or strip metal folded on lines extending longitudinally of said sides, and a diaphragm in union with the inner parts of said sides and integrally formed out of the same piece of'metal therewith, said diaphragm lying in a plane between the top and bottom of the filler.

In witness whereof, I hereunto subscribe my name this 27th day of November A. D. 1907.
