GAR AXLE BOX. No, 337,949. Patented Mar. 16, 1886.

NITED STATES PATENT OFFICE.

THOMAS A. GRIFFIN, OF CHICAGO, ILLINOIS.

CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 337,949, dated March 16. 1886.

Application filed January 5, 1886. Serial No. 187,666. (No model.)

To aZZ whom it may concern:

Be it known that I, THOMAS A. GRIFFIN, of Chicago, in the county of Cool; and State of Illinois, have invented a new and useful Im provement in Oil-Boxes, of which the following is a full, clear, and exact description.

My invention is adapted specially to sliding box-lids, though it may be otherwise advantageously applied. The ordinary sliding lid is without projections on its inner surface, this construction being necessary to allow it to pass the upper edge of the journal-box. Asa consequence, much of the oil thrown against the lid while the journal is revolving will escape unless the joint between the lower edge of the lid and box is made tight by planing both the lid and its seat, and even then some oil will still escape.

To prevent this waste of oil is the object of my invention, which consists of a shield or apron, cast or otherwise conveniently applied, which serves to prevent the slopping of the lubricant, and returns the same to the fount or oil-box proper.

In the accompanying drawings, Figure 1 is a section of ajournal-box; and Fig. 2 is a perspective of alid ready for insertion, showing its construction more clearly.

A is alid having upon its inner face, near its lower edge, the recess B, large enough to contain the strip or apron C, so that when it is folded back into the recess nothing projects from the inner face of the lid, which can be readily inserted in position. The apron C is made ofsheet-iron, tin-plate, or other flexible metal. Its length is slightly less than the width of the opening in thejournal-box, and it is of any desirable widthsay one to one and onehalf inch-and itshould be thin enough to per- I init of bending. Its lower corners may be truncated, or the recess for the apron or shield may be made so large as to allow for the insertion of the fingers or tool used in bending it out.

To put the apron G into a cast lid, I insert it into the mold after the pattern is removed, burying all of it in the sand,except a portion of the upper edge,which is left projecting into the interior of the mold, so that the castiron,when poured.becomes firmly united with it. On removal from the mold the apron is folded back into the recess. After the partial insertion of the lid in the box, so that the apron O is past its upper edge,D, the apron is bent outwardl y from its recess,so as to project into the box. The apron need only be bent back into said recess when it is desired to entirely remove the lid, as it can be opened for ordinary purposes without doingso. NVhen the lid is entirely closed, the parts have the relative positions shown in Fig. 1, it being evident that the oil thrown against the boxlid must be returned again to the fount or oilbox proper.

My invention may be applied to hinged lids with advantage, for the apron O is lighter and less expensive than alip cast on the box would be.

I claim The flexible apron O, constructed substantially as and for the purpose described.

THOMAS A. GRIFFIN.
