JOURNAL-BOX.

Specification of Letters Patent. Patented 17, 1918.

Original application filed November 8, 1913, Serial No. 779,941. Divided and this application filed March 16,

To all whom it may concern Be it known that I, CLAYTON MARK, a citizen of the United States, residing atLake Forest, Lake county, Illinois, have invented new and useful Improvements in Journal- Boxes, of which the following is a specification, reference being had to the accompanying drawings, in which Figure l is an elevation of a journal box embodying my invention; Fig. 2 is a plan thereof partly broken away on lines IIII of Fig. 5; Fig. 3 is a section on lines III-III of Fig. 2; Fig. 4. is a partial rear elevation; Fig. 5 is a section on lines V-V of Fig. 2, and Fig. 6 is a section on lines VIVI of Fig. 2.

My invention relates to journal boxes, and consists in a journal box comprised of two or more parts, in which the top is preferably made of cast metal and the bottom, or oil cellar, is preferably made of ressed or stamped metal, and in uniting tiese parts together by welding.

Various other features comprising my invention are hereinafter described and claimed, the method, however, being claimed in my pending application, Serial Number 7 7 9,941, filed November 8, 1913, of which the present application is a division.

Referring to the drawings, A indicates the top of the journal box, preferably comprised of cast metal, such as malleable iron or steel, because of its somewhat intricate shape, and having the usual hinge lug 2, and the. journal bearing side stops 3. B indicates the bottom part or oil cellar, and C the dust guard wall, both of which are preferably made of pressed steel. The oil cellar B is preferably made without the usual strengthened ribs, and with its top edges 4; unbroken, so that they bear directly against the underface of the top A.

Extending downwardly from the top A are flanges 5, which are adapted to enter inside of the top edges 4L of the oil cellar B and to fit closely thereagainst. When these parts 4 and 5 are thus interengaged they are secured or bonded together by welding. The uniting of the parts may be effected by continuously welding together the contacting faces of the flanges 5 and the top edges l into an integral structure.

Serial No. 14,659.

faces. In either event the result is that the top A and oil cellar B are made, in effect, If desired, the parts may also be welded along thelines c and (Z.

The dustguard wall C fits closely in the rear end of the oil cellar B and forms the inner wall of the dustguard chamber 9. The member C has inwardly-turned flanges 7 and 8 in its lower ortion, which bear against the bottom and sides respectively, and in its upper portion it has also outwardly-turned flanges 10, which bear against the sides of the oil cellar B. The member 0 may be welded to the top A and bottom B along the flanges 7, 8 and 10 where these flanges bear against the inner surfaces of the bottom I made much lighter without necessitating any sacrifice in strength, and with a slight increase in the thickness of the metal the boxes may be made without the usual strengthening ribs. It is, however, not necessary that the bottom of the box be made to withstand the strains to which the top is subjected, since normally the bottom acts merely as an oil cellar, practically all of the strains being transmitted through the top to the side frame, so that from considerations of lightness and cheapness the bottom may be made of much lighter metal than the top.

If desired, the connection between the top and the oil cellar may be made by butt welding the upper edges of the oil cellar against the under surface of the top, as is shown at c in Fig. 6, in which case the downwardly extending flanges will act as reinforcements for the parts.

The terms and expressions herein used are used as terms ofdescription and not of limitation, and I have no intention in the use of such terms and expressions to exclude any mechanical equivalent for the features shown and described, but recognize that various structural modifications are possible within the scope of the invention claimed.

What I claim is:

1. A journal box comprised of a cast metal top, a pressed metal oil cellar, the rear wall thereof forming the outer wall for a dustguard slot, and an inner dust-guard Wall, said Wall being contained in the pressed metal oil cellar and having flanges adapted to be secured to the oil cellar by Welding, said flanges having a bearing on the rear Wall of the oil cellar, and determining the position of the inner dust-guard wall with relation to the rear Wall of the oil cellar.

2. A journal box having its rear Wall forming the outer Wall of a dust-guardslot, and an inner dust-guard wall, said wall be- Gopies of this patent may be obtained for ing wholly contained in said box and having oppositely-directed flanges, one of the flanges determining the position of the inner wall with relation to the rear Wall of the box and another of the flanges serving as means for attaching the inner Wall to the box.
