f IMPROVEMENT l-N JOURNAL-BQXES.

. The Schedule referredv to in these Patent part of the same.

To all lwhom. 'it may concern:-

Beit knownrthat I, JOHN SCHIEDER, of the city, county, and State of New York, have inventeda new and useful Improvement in Journal-Boxes; and I do hereby declare the following to be a fu'll, clear, and exact description thereof, which will enable -those skilled in the art to make aud use the same, reference being had to'the accompanying drawing forming part v.Figure 1 represents a transverse section of this invention, the line a; 2:, ig.- 3, indicating the plane of section. Y

Figure 2 is an end view of the same. A Figure .3 is a longitudinal central section o f the' same, the plane of section being indicated by the line 'yr/a 1 Figure 4 is arv sectional fronti-'ieu' of the`box when' applied to a hanger.

Similar letters indicate corrcspomling parts.

This invention consists in a journal-box which contains two adjnstableshells filled with bearingsurfaces composed of alternate layers of Indiaa'ubber cloth and of sheet metal, sheet-copper being used by'preference, in such a manner that a bearing-surface is obrenewed, and which can be easily adjusted by means of set-screws 4acting on the shells. f

The ends or heads of the box are removable, so that easy access-cau be had to the shells, and to each of said heads is secured a latch, which serves to sup portthe shaft in case the lower shelleshould be re- The journal-box, when used in connectiou'with a hanger, is secured thereto by means of a swivel-arm, which swings on a pivot secured in the hanger, and

screws with right-and-let-hand screw-threads, in such a manner that the journal-box can accommodate itself to the shaft passing through it, and that the nuts on the screws with the right-and-left-hand threads are not liable to work loose spontaneously.

In the drawing- A designates a journal-box, each half of 'which is provided with a shell, B.

These shells are exposed to the action of' set-screws a b c, bearing thereon from three sides, so that the same can be readily adjusted to the correct position after thevbox is secured in its place.

Said shells are fitted with bearing surfaces zZ, coinposed of alternate layers of India-rubber c-lothl and sheet metal, sheet-copper being used by preference, and these layers are united by rivets e passing through them, as shown in g. 3.

By these means bearing 'surfaces are obtained which are self-lubricating, which are very durable, and whi'ci` work with comparatively little friction.

' 'It' either' of said bearingsu'rfaces should wear off,

it can be readily brought in the required position by means of the set-screws a b c, and if the same should wear out it can beeasilyremoved and replacediby a new one. Y

In order to enable the workmen to effect this purpose, the heads f f of the box A are made removable,

being `s'ecuredin vposition by screws g.

To the outei:` surfaces of the lower heads f are secured the latches Tg'which, when the journal-box is in operation, are turned down to thevpositio'n shown in fig. 2; 'but if the bearing surfaces in the lower shells have to .be removed, one of the lower heads is nnscrewed and .taken off, and the latch on the opposite -head is turned up and secured in position, so as to support the shaft` while the shell is taken out.

For the purpose of securing the latches in this lastnandpositiomI have provided them with screws fi, which cau'be screwed into holes j, (see g. 2.)

If my boi; is to be used on a'hanger, C, I provide the vsame with an arm, It, which is attached tol the hanger by means of a screw, l, so that the box can accommodate itself to the shaft passing through it.

In the'a'rin k are two segmental slots,'m, (see tig.`

4,) and` through these slots pass screws `ln, with nuts o, and right-hand threads on one andleft-hand threads on the opposite ends.

'If the boi: should swing Aou its pivot Z, therefore, and if either ofthe screws n `should turn,.having. a tendency to unscrewthe nut on one of its ends, the nut on the opposite, end will screw up, and the box would become tight, or at least prevented from getting loose spontaneously.

What I claim as new, and-desire to secure by Lett-ers Patent, is'- 4 1. A journal-box, containing two shells, provided with bearing-surfaces made of alternate layers ofIndiarubber cloth and sheet'metal, (sheet-copper being used vby preference',) said shells being adj usted by means of set-screws so that the bearing-surfaces can be brought in the required position, as herein shown and'described.

.2. The supporting-latches at the heads of the journal-box, provided with `removable shells, substantially as set forth.

3. rIhe swivel-arm, securedto a hanger by-screws with right -and-left-hand threads, substantially as .l

herein shown and described.
