JOURNAL-Box.

SPECIFICATION forming part of Letters Patent 1\To.392,206l dated November 6, 1888.

Application filed Tune 19, 1888.

To a/ZZ whom, it may concern.-

Be it known that I, JOE E. JoHNsoN, a citizen of the United States, residing at Waldo, in the county of Columbia and State of Arkansas, have invented new and useful Improvements in Journal-Boxes, of which the following is a speciiication.

My invention relates to `improvements in journal-boxes,having for its object to provide asiniple and eieetive means to adjust the bearing to compensate for Wear; and it consists in a certain novel construction and arrangement, fully set forth hereinafter in connection with the accompanying drawings, wherein- Figurel is a longitudinal sectional View of a journalbox embodying my improvements. Fig. 2 is a transverse sectional viewthcreof through one of the adjusting-blocks. Fig. 3 is a detail perspective view of one of the adjusting-blocks.

Referring to the drawings, this box is adapted to be employed in all kinds of machinery,either heavy or light, the object being to provide means whereby the wear may be taken up as it becomes apparent, the means being adapted' to be nicely adj usted to take up all play without binding thespindle.

I am aware that it is not new to insert small wedges or blocks under the cap-plate of the box,and as the bearing wears reduce the thickness of the said block and thus permit the capplatc to be lowered, but it will be seen that much difliculty `is experienced in this manner of adjustment to reduce the thickness of the blocks exactly enough to properly adj ust the bearing, and, further, much time is occupied in adjusting a bearing in this manner.

A designates the pillow-block oi' the improved box having the lower half of the bearing therein, and B designates the cap-plate, which is arranged above the pillow-block and is provided with the upper hall of the bearing. The pillow-block and cap-plate are provided,respectively, with registering apertures a b, the apertures a being tapped, as shown in the drawings.

The bolts O C are screwed at theirlower ends into the tapped apertures in the pillow-block, and are provided with rigid (and preferably integral) collars D D, to fit in sockets or de- Serial No. 277,530. (No model.)

pressions E E around the upper ends of the tapped apertures.

F F represent adj usting-blocks having apertures f f therein, which register with the apertures a in the pillow-block and 'receive the upper ends of the bolts C C,and the said blocks fit in transverse channels or grooves G G in the upper side of the pillow-block and bear on the upper sides ol' the collars D.

The apertures b in the cap-plate receive the upper ends of the bolts, and the set-nuts H, which are screwed on the extremities of the bolts, bear on the upper side ofthe cap-plate and hold the latter firmly pressed on the adjusting-blocks. The upper ends of the bolts are squared to receive a wrench or a key to enable thelower ends ofthe bolts to be screwed into the tapped apertures in the pillow-block.

The manner of connecting the parts of this journal-box will now bereadily seen. The bolt's are screwed in the apertures in the pillowblock. The adj listing-blocks are arranged on the bolts above the collars, and after the spindie has been arranged in the bearing the capplate is arranged on the upper ends of the bolts and allowed to bear on the upper sides of the adjusting-blocks. The bolts are now screwed up or down in the pillow-block until the capplate bears properlyon the upper side of the spindle, after which the sctnuts are engaged on the upper ends of the bolts and screwed down, so as to tightly clamp the cap-plate against the adjusting-blocks. As the bearing becomes worn, the cap-plate may be lowered by first disengaging the setnuts and then screwing the bolts down into the pillow-block.

It will be seen that the adj usting-blocks are vemployed to distribute the pressure of the collars on the under side of the cap-plate and thus support the cap-plate evenly. The adjustingblocks are also employed to prevent a longitudinal movement of the cap-plate, as might be the result if the portions of the bolts between the pillow-block and the cap-plate were unsupported. sides of the said blocks iit snugly in the channels or grooves of the pillow-block and their upper sides are in contact with the lower side of the cap-plate. These adj usting-blocks may be formed integral with the cap-plate, if pre- It will be seen that the lower 9 ferred; but I consider it advantageous to have them separate.

The adjusting device described is simple and e'ective, it consisting simply of verticallyadjustable bolts having rigid collars which support the capplate in any desired position, and the bearing is adjusted without removing any of the parts thereof with the exception of the clamping-nuts. Fn1ther,these Setnuts are not liable to jar loose, as the elasticity of the metal collars and adj ustingblocks forms a lock which holds the said nuts firmly in position.

It will be observed that the adj nsting device is entirely independent of the construction of the bearing, and by making the described apertures and channels or grooves it may be applied to any bearing now in use. Therefore I do not wish to limit myself to the peculiar construction of bearing herein shown.

Having .thus described my invention, I claim- 1. In ajournal-box, the bolts C, arranged at their lower ends in the pillow-block on opposite sides of the bearings and having rigid collars D thereon, in combination with the capplate mounted on the bolts and supported by the said collars, and the set-nuts engaging the upper ends of the bolts and bearing on the capplate, substantially as specified.

2. In a journal-box, the bolts arranged in tapped apertures in the pillow-block and having rigid collars, and the adj usting-hlocks arranged on the bolts and bearing on the said collars, in combination with the cap-plate l bearing on the adjusting-blocks and the setl nuts engaging the upper extremities of the bolts, substantially as specified.

3. In ajournal-box, the combination of the pillow-block A, having the tapped apertures a, the depressions or sockets E at the upper ends of the said apertures, andthe transverse channels or grooves G, communicating with the said depressions or sockets, the bolts mounted in the tapped apertures and each having a squared upper end and a rigid co1- lar arranged at an intermediate point and adapted to tit in the said depressions or sockets in the pillow-block, the adj ustingblocks having apertures receiving the. bolts and bearing on the said collars thereon, said adjustingblocks being adapted to tit snugly in the chan nels or grooves G,the cap-plate having smooth apertures b, registering with the apertures ain the pillow-block and receiving the upper ends of the said bolts,and the set-nnts engaging the upper projecting ends of the bolts and bearing on the upper side of the cap-plate to clamp the latter firmly against the adjnsting-blocks,snb stantially as and for the purpose hereinbefore specified.

In testimony that l claim the foregoing as my own Ihave hereto affixed my signature in presence of two witnesses.
