JOURNALNBOX.

SPECIFICATION ferraille part of Letters Patent Nou 309,582, dated December 23, 1884.

Application tiled May QQ, 1884.

To all whom, it muy concern:

Be it known that I, JOHN E. Swnn'r, of Syracuse, in the county of Onondaga, in the i State ofNew York, have invented new and usethe following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

rlhis invention consists in a novel construction of a solid journal-box having bearings which `are easily adjusted to compensate for the wear thereof, and thus prevent pounding of the same without danger of prod ucing undue binding and friction thereon, and which, furthermore, are readily renewed at very little er pense.

The invention is fully illustrated in the annexed drawings, wherein Figure l is an end Fig. 2 is a longitudinal section thereof'. Figs. 3 and Ki are respectively a longitudinal and a transverse section of the solid box'. Figs. 5 and 6 represent, respectively, a side view and a transverse section of one of the cheek-pieces; and Figs. 7, 8, and 9 are plan, edge, and end views of the key or wedge which is employed be tween the thick edges of the check-pieces.

Similar letters of reference indicate cpi-re spending parts. i

A represents the solid box, in the form of a cylindrical shell having an eccentric circular bore.

B 'B denote cheek-pieces having segmental inner and outer faces, the latter of which corthe inner face is eccentric to the outer face. Said clieelepieces are applied to the interior or bore of the solid shell A, with the thick portion of the former on the thin portion of the said shell, so as to bring the inner. faces of the cheekpieces concentric with the exterior of the external shell, A, and thus maintain the shaft in line. The interior of the thick or bottom portion of the shell A is provided in its center with a longitudinal spline or feather, c, against which the thin edges of the cheekpieces B B abut, the latter being thus maintained uniformly distributed on opposite sides ofthe journal-box, which feature is very cssential, inasmuch as it serves to maintain the interior of the cheek-Pieces in concentricity (No model.)

with the shaft, and prevents either ofthe cheekpieces become worn by the friction of the shaft revolving thereon a sufficient number of the liners are removed from their aforesaid position and placed by the side of the wedge D, to cause the cheek-pieces to move toward the bottom ofthe box, and thereby take up the play and become properly sea-ted to prevent pounding ofthe bearings on the shaft. By proper care of the aforesaid adjustment all danger ofthe bearings of the cheek-pieccs becoming unduly bound or tightened on the shaft, so as to cause the parts to become heated by friction, is obviated. After all theli ners have been shifted, as aforesaid, strips of considerable width can be cut from the lower edges ofthe cheek-pieces, and other liners introduced at the sides of the spline, so as to get additionalwear out ofthe cheek-pieces.

E represents a lubricating ring employed to return the oil from the drppocket to the top of the shaft, the operation thereof being well understood and needs no detail description in this case.

lt will be observed that by the described construction and combination of parts l obtain a solid box, which cannot give way or getloose, and is devoid of j oints for the escape of the lubricant either at the bottom or sides.

Having described my invention, whatI claim as new, and desire to secure by Letters Patent, is-

l. A journal-box comprising a solid shell having a circular bore, and eccentric cheekpieces applied to the said bore, substantiallyv as described and shown.

2. A journal-box composed of an external solid cylindrical shell having an eccentric circular bore, and. internal cheek-pieces having segmental inner and outer faces eccentric in relation to each other, and placed with their thick portion on the thin portion of the aforesaid shell, substantially as shown and set forth,l

IOG

A journal-box comprising a solid shell having a central bore, a spline on the bottom portion of said bore, and eccentric cheek-pieces applied to the said bore, and sustained by their abutment on the spline, substantially as specified.

4. In a journal-box, the combination oi' a solid shell having a circular bore, eccentric cheek-pieces applied to said bore, a wedge or key inserted between the thick ,edges of the cheek-pieces, and liners removably interposed between the adjacent thin edges ofthe cheekpieces, substantially as described.

5. In a journal-box7 the combination of a solid shell having a'circular bore, eccentric cheek-pieces applied to said bore, a spline or feather secured to said shell between the thin edges of the cheek-pieces, and liners removably inserted between the aforesaid i'eather and adjacent edges of the cheek-pieces7 substantially as shown and set iorth.

G. In a journal-boxthe combination of a solid shell having a circular bore, eccentric .cheek-pieces applied to said bore, a spline in the bottom portion of the bore, liners interposed betwecn said spline and thin edges ofthe cheek-pieces, and a wedge inserted between the thick edges of the cheek-pieces, all constructed and combined substantially in the manner speciiied and shown.

In testimonywhereof Ihavehereunto signed my name and aiiix'ed my seal, in the presence of two attesting witnesses, at Syracuse, in the countyof Onondaga, in the State of New York, this 15th day of May, 188i. i
