JOHN H. ALLEN, OF BROOKLYN, NEW YORK.

JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 236,868, dated January 25, 1881.

Application led November 18, 1880.

To all whom t may concern Be it known that I, JOHN H. ALLEN, of Brooklyn, in the State of New York, have invented a new and Improved Journal-Box, of which the following is a specification.

Figure I is a sectional elevation and partly front view. Fig. II is partly a top view and one-half in section at center of shaft.

Similar letters of reference indicate corresponding parts.

This invention, which is more particularly intended for pillow-blocks cast upon the bedplate of the engine, consists in making the wedges on. each side, which act against the side cheeks, to extend the whole length of the cheeks or the wh ole length of the bearing, with straight surfaces at their inner side, nekt to the cheeks, and with cylindrical outer surfaces fitting into cylindrical surfaces ot' the pillowblock jaws, whereby the journal-boxes, together with the wedges, can turn in'the pillowblock, if, at any time, the shaft should come piece, n, are iitted square upon the bottom of (No model.)

the pillow-block and against the Linder side of the cap K;

The keys or wedges H H. are made cylindrical on their outside, and placed in contact with the inclined and cylindrical surfaces of the jaws G G, while their straight surfaces are placed in contact with the straight outer surfaces of the side pieces, w w. The wedges H H are moved by means of suitable screws J J passing through the capK, and by this means adjust the side pieces, w w. By this arrangement and construction of making the outside of the wedges H H inclined and concentric, fitting against corresponding surfaces in the jaws G G, an equal bearingis obtained against the side pieces, w fw, in their whole length, and consequently these side pieces or bea-rings, w fw, can be made to bear evenly against the whole length ot' the journal ot' the shaft, even if said shaft should be slightly out of line.

What I claim as my invention, and desire to secure by Letters Patent, is-

In combination with the side pieces or side beariu gs, w w, of a journal-box, the wedges H H, provided with concentric inclined outer surfaces tting against corresponding surfaces in the inside of the pillow-block jaws G G, arranged in the manner and for the purpose suhstantially as described.

JNO. H. ALLEN.
