UJUSTABLE SUPPORT FOR JOURNAL-BOXES.

SEEGIFGATIQN forming part of Letters Eatent No. 675,411, dated June 4, 1901. implication tiled January 2l, 1901. SerinlNo. 44,065. (No model.)

To all whom 'may concern:

Beit known that I, JAMES L. RECORD, a citizen of the United States, residing in the city ofMinneapolisounty of Henncpin,and State of Minnesota, have invented certain new and usefulImprovements in Adjustable Supports for Journal-Boxes, ot` which the following is a specification.

My invention relates to adjustable supports for the journal-boxes for shatting employed in buildings to operate machinery and i'or various purposes.

The object of the invention is to provide convenient means for the support of bridgetrees upon which the boxes are mounted and for the vertical and lateral adjustment of the bridge-trees and of the boxes upon them.

The improvements, generally stated, relate to sills attached to posts of a building, a bridge-tree supported on the sills by means of leveling-screws and adjustable both vertically and laterally relative to the sills and posts, and means tor adjusting the journalbox laterally ou the bridge-tree. Such improvements are illustrated in the accompanying drawings, in which- Figure 1 shows the posts, sills, bridge-tree, journal-box, and adjusting' devices in elevation. Fig. 2 is a plan view of the bridge-tree detached. Fig. 3 is a front elevation of the sills and leveling-screws detached from the other parts. Fig. -1 is a plan View of the same. Eig. 5 is an end view ofthe same. Fig. Gis a detail vieu7 of one ot' the leveling-screws, and Fig. 7 is a detail view of the nut used thereon.

In the drawings, 1 designates one of the metal posts of a building, which, as shown, is of I form in cross-section. Sills 2 ot1 angular shape extend from one post to the other and are supported at opposite sides of the posts on angle-plates and e, on which they are seated, and are also secured by angle-plates 5, that connect their upper surfaces to the posts. The sills when so attached are separate and provide an intermediate space to receive the leveling-screws. To prevent spreading at the middle, a plate G is riveted to the lower tlanges of the sills,and at both sides of the middle plaies are riveted to the upper iianges.

The leveling-aerei ys S operate through openings in the plates if. These openings are of angular form to provide sockets for the angular lower portions 9 of nuts 10, that have lateral shoulders 11 seating on the plates 7. The screws 8 operate in these nuts, which are suitably threaded, and the upper portions of the screws have angular portions 12 to adapt them to be turned by means of a wrench for the purpose ot' raising or lowering the bridgetree 13, which they support.

The bridge-tree is in lform o1` a channel-bar (a web having two downward flanges) a little longer than the distance between the posts and having notches 14 in its ends to receive the posts for guiding its movements. To adjust it lengthwise-that is, from one post toward the other-set screws 15 are passed through standards 16 von the bridgetree and arranged to bear against the posts. Thus either or both ends of the bridge-tree can be adjusted vertically by turning the leveling-screws which support it, and it can be adjusted longitudinally by the screws 15, and the ends are guided and prevented from lateral movement by the posts which engage in the slots.

A base-plate 17 for the journal-box is secured to the bridge-tree by bolts 18 and has upward projections 19, through which setscrews 2O pass and bear against the sides of the pillow or base 21 of the journal-box, and by turning the latter screws the bearing-box can be laterally adjusted.

By suitable adjustment of these devices the sha'fting can be kept in proper alinement when from unequal settling ot' the building or other cause there is occasion for adjustment of the journal-boxes.

Having described my invention, what I claim is` 1. The combination with posts, of a vertically and laterallyadj ustable bridge-tree slidable between and guided by the posts, ajournal-box mounted thereon, leveling-screws for supporting and raising and lowering the bridge-tree, means connected to the posts for supporting the leveling-screws, and screws mounted on the bridge tree and bearing against the posts for adjusting the bridgetree in lateral direction, substantially as set forth.

2. The combination with posts, of a vertically and laterally adjustable bridge-tree slid- 3. The combination With posts and sills secured thereto, of leveling-screws supported by the sills, a bridge-tree mounted upon said screws and vertically adjustable by means thereof, adjusting-screws mounted on the I5 bridge-tree for the lateral adjustment thereof'by engagement with said posts, a journalbox adjustably mounted on the bridge-tree, screws for its lateral adjustment thereon, and means for the support of such screws on the bridge-tree, substantially as set forth.

In testimony whereof I have hereunto set my hand this 12th day of January, 1901.

JAMES L. RECORD.
