' rnnssnn-srnnn JoUnnAL-Box.

To all whom it may concern I Be it knownthat L'ALVIN G. fMcCoRn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented 'certain'new and useful Improvements in Pressed-Steel Journal- Boxes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as'will enable others skilled in the art to which it 'appertains to make and use the same.

Particularly, my invention'has for its obj'ect' to provide an improved all pressed steel journal box in which the box proper may be stamped or'pressed from a single piece of sheet steel, and to such ends, generally stated, the invention consists of the novel construction and combination of parts hereinafter described and defined the claims. The invention involves two main novel features and'certain other important minor features.

The first of the said main. novel features consists in forming the cellar and top ofthe box from a single piece of sheet steel, by providing integral extensions from thesideforming portions of the sheet and bending these, one over the other, and overlapping the same to form the top or roof of the box. This construction not only reduces the number of parts of the boxbut provides a very strong top in which the overlapped inner and outer top forming plates will be held together by the weight or pressure on the top of the box, and thereby very greatly reducing the necessity of welding or otherwise connecting the said top plates. 7

The second principal novel feature consists in forming the pressed steel cellar of the box with an integral inwardly-pressed corrugation or rib that constitutes the inside dust guard wall. This dust guardwall may be produced as a part of'the operationrequired to press the sheet into the form of a cellar, and hence, reduces the cost, eliminates the necessity for welding and provides an oiltight joint whichwill prevent leakage of oil 'fIOITL'thB cellar into the dust guard seat.

In the accompanying drawings which illustrate the invention, like characters indicatelike parts throughout the several views.

First note the construction illustrated in Flgs. 1 to 6, inclusive' From the blank stamped as shown in Fig. 1, the cellaror body 1 of the box is pressed into the form shown in Figs. 2 to 6, inclusive. Here it may be noted that the bending'lines, of the blank, Fig. 1, are indicated by dottedlines marked y, yfiyflg and y. l The side forming portions of the box are between the

bending llnes

2 and 3 The plate 2 is bent ion line and constitutes the inner top formng plate, and it is bent on the line 2 3 to form a depending flange 2 that engages against the inner upper surface of one side of the cellar. By bending on the inner line y, the outer top forming plate 3 is extended over the entire top of the box and is brought down against and overlapped with the said inner top plate 2; and by bending on the 'lines l depending flanges are provided which overlap with the outer upper surfaces of the sides of the box. The cellar 1 is provided with depressed bosses 4: that flatten the bottom" thereof for engagement with the lower archbar, and in approximately the same transverse vertical plane, the sideforming portions of the cellar are provided with inwardly-pressed bosses or bulges 5 that afiord center brassestops. On a proper transverse line between the bosses t and the inner end of the box, the blank is formed with a deeply pressed rib or corrugation 6 that extends across the bottom and well up the side-forming portions of the sheet, and which, when the cellar is pressed into shape, has a segmental form, as best shown in Fig. 6, and constitutes the inside dust guard wall of the box. By bending the narrow portions I of the blank, 1, on the lines g g upon themselves, and thence downward against the sides of the box, ,asbe'st shown'in Fig. 3, the box is provided with outwardly pro ecting lugs 7, that are perforated at8, so as to pass the archbar bolts. At its transversely central outer end portion, the outer top I forming plate 3 has an integral upwardly pressed hollow lid hinge lug 9 that may be located in an upwardly bulged portion on a the said plate, but in any event, properly positioned in respect to the integral: inside dust guard wall 6,'softhat the dust guard '(not shown) will be properly positioned between the same and the inner end flange 12 of the cellar. The depending flanges onthe top forming

plates

2 and 3, which overlap the sides and inner end of thecellar, would usually be connected by spot-welding, and if lugs desired,said

plates

2 and 3 may also be spotwelded. Approximately in line with the arch bolt lugs 7 the top plate 3 is formed with one or more raised corrugations 13 which, increase thestrength of said plate and afford a suitable top arch bar seat.

Theconstruction illustrated in Figs. 7 to 11, inclusive, is very much like that llustrated in Figs. 1 to 6, inclusive, but differs therefrom in that both of the top-forming

plates

2 and 3 are directly united to the cellar forming portion of the blank, and the reduced portion 1 1, which forms the top arch bar seat or seating yoke, is projected entirely from one side of the outer topforming plate 3. In forming the boxfrom the blank 7, the outer plate 3 is folded on top of the inner plate 2, as noted ,in the description of the formation of the box from the blank 1, and thereafter, the arch bar seating yoke 14: is bent on the lines marked m M, to thereby cause the said yoke to project and serve as. arch bar lugs, and which are provided with suitable bolt holes 15. Otherwise than noted, the box shown in Figs. 8 to 11, may be assumed to be identical with that shown in Figs. 2 to 6,

inclusive, although the lid hinge lug 9 which is pressed from the other top-forming plate 3, as illustrated,'diflers from the lug 9 in the particulars not necessary for the purposes of this case to consider.

What I claim is:

1. A pressed sheet metal journal box having integral extensions from two of its wallforming portions, overlapped with each gther to form one of the other Walls of the 2. A'pressed sheet metal journal box having integral'extensions from its side-forming V portions,* overlapped with each other and forming the top of the box.

A journal box constructed'from a single piece of sheet metal having extensions from its side wall-forming portions, overlapped with each other and each spanning the box and together forming the top of the box, the outer of said overlapped top forming extensions having an upwardly depressed lid hinge lug, at the outer end of the box, and having a dust guard opening at the inner end of the box, said inner of said top-forming extensions having depressions aflording outer wedge stops, and the sides of said box having nwardly bulged portions constituting center wedge stops.
