IMPRVEMENT IIN JOU RNAL-BOXES.

l The chedulereferred to in these Letters Patent and making part of the same l, ELIzADExTna Muneer, of New York, county of New York, State of New York, have invented Iniprovementsin J carnal-Boxes, of which the following `Desomptton of the Acoompanymg Drawmg. Iligure "l is a a sectional elevation of my improved Figure 2, a perspective view ot` a detachable carrier for holding the bearing.

Figure 3, a section ou the line 1 2, iig. 2. Figures 4 andv 5, views showing n'xodiications.

"General Description. The box A consists of ahollow metal cylinder-,in he upper edge of which are recesses for the reception of the bent ends of curved springs a, ,which extend `downward within and nearly, to the ottom of the box, bearing against the latter `onl y at ieirends.

Against the upper bent ends of the springs bears the iiauge c of a cap,fl, which screws onto the upper end of thebox, and` contines the springs iu their places. A detachable cylindrical frame, B, consisting (in the present instance) of a slotted tube, with a flange, a, at the lower end, tits within the box, and is of such a diameter that, when introduced from below, it will tend t-o compressor flatten the springs a, and will be retained bythe saidspriugs' iu the central position shown in figs. 1 and 2. l r v Upon the frame B is a springcatch, c, adaptedto a recess, i, in the box A, and which retains the frame iu its position vertically, and in the box slides a pin, j; which, when pressed inward, will force 4the catch out of the recess so that the box may be withdrawn.

The packing, which may be of the prepared material for which Letters Patent of the United `States were granted to'me ou the. 12th day of July, 1870, is folded to a tubular form and introduced into the frame or carrier B,Aand the latter is secured in the box A, as shown in iig, 1. l

The springs a will prevent any excessive vibration of the shaft, yet when any strain is brought upon the latter tending to defect it, will yield suiiciently to` prevent the straining or bending of the shaft and the unequal wear of the bearing.

The carrier is especially serviceable when it is necessary to replace the bearing without disturbing the shaft or the box. This is accomplished bysliding the carrier down upon the spindle, removing the defective bearing, wrapping another round the spindle, passing the holder up over it, and then sliding both np'iuto the box.

Should it 'be necessary to 'remove one or more of the springs a., the cap dlrnay be uuscrewed and the spring or springs withdrawn without disturbing the box or bearing.

Corrugated elastic rh gs, a2, tig. 5, or a tube of rub.-

ber,or other elastic material, may be substituted forV the springs a, and insomeinstauces the holderB may be dis )ensed with, andthe bearing an may rest directly against the springs or elastic material, as shown [in fi|r 4 V aIn this case thcbearing :t should be expanded at the lower end to form afiange, and the box should b e provided with -a detachable ring or cap, I, for clampfing the said iiange, thereby preventing the bearing from being displaced orturniug inthe box.

It will be apparent that `my invention maybe Vas eciently employed with sliding shaftsas with those which revolve. g l Y Claims.

l. The mnnhination olf the box A, its bearing x, and au elastic medium arranged between the bearing and the box, snbstantiallygas described.

2. The'ombination, with the box A, of a detacha ble` carrier B, for Yholding the bearing, as speoied.

3. The ring or cap c, securing the flanged bearing `to, the box, as set forth.

In testimony whereof I have signed my name tothis specification in the presence of two subscribing witnesses.

E. D. MURFEY.
