To all wh0m it may concern:

Be it known citizen of the United States, residing at a bench, the removable back plate E, the Louis, 1'n the State 0 Missouri, have invented drift-p' for knocking the casting out of certain new and seful Improvements in Metal Molds for Making Brass Oastin s; and I do declare the following clear,

the mold, all'beingfeatures of the patent re ferred to above. Further it is readily seen that I have made several changesas follows: Have taken off the vertical side gate opening with its four branch openings into the mold-cavity, also taken off the sinker 19 on the top of the mold, discarded the clamp to be a fu and exact description of the invention, such as' will enable others skilled in the art to which it appertains to make and usethe same, reference being had to th e accompanfym rawings, and to the letters and figures 0 re shown 1n Fi 6, and made parts loose and erence marked thereon, WhlCh form a part of changeable t at were solid. Further, I have this specification.

y invention relates to improvements in brass castings or railroad car and engine journal bearings,- and the objects of my improvements are to perfect certain defective molds infuse and to a (1 new, desirable, and valuable features to facilitate the manipulation of the molds; to lessen the cost of the castings made in them, and to save coke or oil, labor, and metal and the useless waste and melting of the metal for the same in gates and sinkers and avoiding grinding. These herein specified and claimed lIIlPlOVOHlCIlt-S are on Patent- No. 726,523, dated April 28, 1903, the invention added the following new features, such as chambering out the to s of the twov moldseetions and inserting oose plugs or cores D D, made of iron, hard sand, or compose tion. These plugs or cores are provided with two gate-openin s into the internal cavit of the mold and orm the up er end surface of the mold-cavity and may e made in two parts or solid in one piece, and the molten metal ma be poured either in one or both of .these said ate-openings, thus allowing easy "escape for the as from the mold-cavity and roviding am e ate and sinker capacity to lpld up the slirin lrage of the casting and at t e hin ed together so as tkfwork-asgpecified,

In testimony whereof I affix in presence of two witnesses.

the mold; also the side of the level is provided with a hook-arm K, (see Fig. 7,) which passes by the motion of the lever over the cope side B of the mold and locks the two sections together. Thus the locking andthe o ening of the mold is done by the action of. t e one lever, which saves time in the manipulation of the mold. Thus I have shown features and their advanta es as separate from the old. i therefore (lo-not claim this construction broadly; but

What'i do claim as new, and desire to secure by Letters Patent, is
