PRINTERS FURNITURE.

Specification of Letters Patent.

Patented Aug. 26,1913.

To all whom it may concern:

Be it known that I, JOHN A. FnAsnn, a citizen of the United States, and resident of Benton Harbor, in the county of Berrien and State of Michigan, have invented certain new and useful Improvements in Printers Furniture, of which the following is a full, clear, and exact specification.

This invention relates to improvements in printers furniture, and particularly to fillers for use in filling up spaces in setting up and completing printers forms heretofore produced by casting, and in some instances from two pieces of sheet steel, the diaphragm being in one piece and the rim in another piece, the ends of the rim. being secured by a dove tailed joint, and the diaphragm being provided with lugs projecting through perforations in the sides of the rim. Cast fillers, when from soft metals, of which lead and its alloys are an example, are not :apable of successfully withstanding the repeated compressions or forces to which they are necessarily subjected, and when of cast iron are frequently broken owing to their brittleness, while on the other hand when a filler is made from two pieces of steel ointed together to form the rim and diaphragm, as above described, these compressions force the joints apart, and in some instances deflect or bend the rim out of shape owing to its weakness due to the perforations therein and its tendency to rust on and break off the lugs projecting from the diaphragm therethrough. Furthermore the dove tailed jointed ends of the rim involve a loss of metal and strength in the rim that it is desirable to avoid.

The object of my invention is printers furniture, and particularly a filler, composed of two pieces of sheet steel, each of which is provided with a diaphragm adapted to be conveniently and permanently secured one to the other by welding, soldering or riveting, and an otherwise jointless continuous rim integral with the diaphragm, whereby a filler of maximum strength, resistance to pressure, durability and economy of construction may be produced and in the absence of waste metal in the formation of a filler.

With these ends in View, my invention finds embodiment in certain features of novelt-y in the construction, combination and ar rangement of parts by which the said objects and certain other objects are hereinafter attained, all as fully described with reference to the accompanying drawings, and more particularly pointed out in the claims.

In said drawings :Figure 1 illustrates, in perspective, a filler embodying my invention. Fig. 2 is a top plan view thereof. lug. .3 1s a longitudinal sect-1011 on the line 8-8 of Fig. 2. Fig. 1 is a transverse section on the line 1 l of Fig. 2; and, Fig. 5 is a plan view of a blank from which the entire one half of a filler is formed.

Similar characters of reference indicate the sameparts in the several figures of the drawings.

In carrying out my invention I first form two blanks 6 from sheet steel, and by a bending and drm-ving process simultaneously turn up the side and end portions thereof, as respectively indicated by the dotted lines 77 and 8-S, whereby end flanges 99 and side flanges 10-10 are formed from each blank, as indicated in Figs. 1, 3 and 1-, so that when completed there results a diaphragm surrounded by and contiguous with a continuous rim extending at a right angle to the diaphragm. After so forming the two parts their respective diaphragms are then rigidly secured together either by soldering, riveting or welding, but preferably by electrically welding them at intervals, as indi: cated by dotted lines at 1111, or may be by one or more rivets 12.

By forming a filler or other printers furniture, as may be, in two parts from sheet steel, and then securing them together in the manner above described, it will be readily observed that the production of fillers and other printers furniture is made practical and possible from sheet steel as the best and most e'llicient material for successfully resisting the force of strain from every direction they may be subjected to without the possibility of the bending of the rim or separating the two parts, for when properly joined both lateral and compressive strains are uniformly distributed simultaneously throughout the filler in every direction, with the result that even a single rivet or spot weld is sufficient to hold the two parts as one when operatively in use.

\Vhile I have shown and described the embodiment of my invention in a printers filler specifically, it should be understood that my invention includes any and all other forms of printers furniture and devices capable of being formed of two pieces of sheet steel, the rim of which is continuous and integral with any base support therefor.

Having described my invention, what I claim and desire to secure by Letters Patent is 1. As a new article of manufacture printers furniture consisting of two pieces of sheet steel, each of which is provided with a continuous jointless rim integrally bent therefrom and means connecting said pieces together, substantially as described.

2. As a new article of manufacture print ers furniture consisting of two pieces of sheet steel each of which is provided with a continuous jointless rim respectively integral therewith, and oined together to form a diaphragm therefor, substantially as described.

3. As a new article of manufacture, printters furniture consisting of two pieces of JOHN A. FRASER.
