Specification of Letters Patent.

Patented Aug. 21, 1906.

Application tiled May 7,1906. Serial No. 315.649.

To fir/ZZ whom, t muy concern:

Be it known that I, WILLIAM L. KArLon,

a citizen of the United States of America, re-

siding at Allegheny7 in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Bearings, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to bearings, and more particularly to pillow-blocks and means for adjusting the same, the primary object being to provide simple and effective means -for adjusting the pillow-block without disturbing the brasses or like packing of the shaft in the bearing or raising the shaft independently ofthe pillow-block.

The invention is specially adapted for millwork, and it is designed to save time, labor, and expense by avoiding the necessity of raising the shaft and repouring a bearing when the latter becomes unduly worn by continuous use.

The construction of the improved bearing will be fully described hereinafter in connection with the aecon'ipanying drawings, which form part of this specification, and its features oi novelty will be set forth in the appended claims.

In the drawings, Figure I is a view in perspective of a bearing embodying the invention. Fig. 2 is a side elevation of the saine with parts thereof indicated by dotted lines. Fig. 3 is a top plan view of the base or bottom casting with the adjusting devices in position thereon, but with the pillow-block removed. Fig. 4 is a side elevation of the bottom casting, parts being indicated by dotted lilies. Fig. 5 shows a side elevation and end views of one of the adj listing-wed res. Fig. 6 is a section on the line 6 6 of Fig. l with the adjusting-wedges removed. Fig. 7 is an end elevation of the hearing, and Fig. S is a section on the line 8 8 of Fig. 2.

The reference-numoral 1 designates the base or bottom casting of the bearing, having an integral projection 2 on its under side adapted to be embedded in a concrete foundation to anchor the bearing securely in lace. The end walls 3 extend upwardly Yrom thebase inward from the ends of the latter and are connected by side walls 4, each of which is formed with inwardly-inclined recesses 5 to accommodate driving-key blocks 6, which key the pillow-block 7 against endwise movement, Side movement of the pillow-block is prevented by the opposite side walls of the bottom casting. The upper surface of the base I is formed with` parallel vertical partitions 8, extending from one end wall of the casting to the other and, together with the side walls, forming a plurality of guideways 9 to receive llanges 10, depending from the under surface of the pillow-block and the wedge-shaped adj Listing-keys] 1j7 the specific construction of which will be described hereinafter. The lower section 12 of the bearing is formed integral with the pillow-block, and the removable upper half 13 of the bearing is secured thereon removably by bolts l-I and nuts 15, said bolts being inverted and applied io the lower section of the bearing through slots I 6. A suitable oil-box 1T is mounted above the upper halt of the bearing to supply lubricant to the shaft. The und er surfaces of the tlangcs 10 of the pillowbloek are beveled, as shown in Figs. 2, 4, and 6, the base of each alternate flange being in reverse direction to adapt them to Iit the oppositely-disposed wedge-shaped adjustingkeys, which` are disposed alternately in opposite directions to maintain the level position of the pillow-block. The bottom of each of the guidcways E) is also inclined or beveled to correspond to the beveled surfaces of the wedges.

Referring now particularly to Figs. 3 and 5, cach of the wedges I] provided at its smaller end with a screw extension 18, two of which extend. through openings in one of the end walls of the casting7 while the other two extend through similar openings in the opposite end wall, lock-nuts 19 being fitted upon the projecting ends ot said screw extensions, as shown. the adjusting-wedges is formed with a vertically-disposed dovetail groove 20, adapted to receive a correspondingly-shaped tongue 21, formed on the extremity of an adjustingscrew 22, said screws extending through suitable openings in the end walls of the casting and being provided with square heads 23 and lock-nuts 24. The pillow-block is held by screws 25 and nuts 26, said screws entering openings 27 in the partitimis Si'. When it is desired to adjust the pillow-block, the nuts 26 and keys 6 are irst loosened, and then by manipulating the screws 22 the wedges are adjusted longitudinallyr to raise the pillowblock to the position required to compensate for wear upon thc shaft-bearing. It will bc apparent that by means of the improved rlhe larger end of cach of IOO IIO

mechanism described. the pillow-block may le adjusted and maintained in a level tion, and hence that the repouring o" the bearing-packing when` worn is obviated.

l reserve the right to make all such minor changes or modifications as may fall within the purview of the following claims.

That l Claim, and desire to secure by Letters Patent, isi-- l. A shaft-bearing comprising a base having a plurality of vertical partitions providing guideways thereonl the bottoms oi which are inclined,` a pillow-block having depending flanges beveled on their under surfaces, oppositely-disposed adjusting-wedges in said guideways below the pillow-block, and means for adjusting said Wedges longitudinally.

2. In a shaft-bearing, the combination with a base-Casting, having a plurality of parallel vertical partitions dividing the base into guideways having inclined bottom surfaces, said surfaces being inclined alternately in opposite directions, the end walls of said base-casting being formed with openings, ot a plurality of adjusting-\vedges within said guide rays alternately disposed in opposite directions, and formed with screw extensions i projecting through the openings in the end walls of the base, and a pillow-block having alternate opposite/ly-inelined depending flanges.

3. The combination with a base-casting having parallel guideways inclined alterosinatal)T in opposite directions, the end walls o1c said casting being provided with o enings7 ot oppositcly-disposed adjusting-wedges within said guideways, formed with screw extensions at one end and with dovetail grooves at the opposite end, adjusting-screws formed with tongues to engage said dovetail grooves, and a pillow-block having depending ianges projecting into said guideways above the adjusting-wedges and having their under surfaces ii'iclined` to correspond to thc bevel of said wedges.

4. ln a shaft-bearing, the combination With a hase-casting having parallel guideways, the bottoms oi which are beveled alteriiately in opposite directions, of adjusting-wedges within said guideways arranged alternately in opposite directions and havingscrew eX- tensions and` dovetail grooves, lock-nuts arranged on said` screw extensions, adjustingscrews extending through the end walls of the casting and formed with tongues fitting the grooves of the adjListing-wedges, and a pillowblock having depending flangesJ the under surfaces of which are alternately beveled in opposite directions to adait thein to the inclined surfaces of said We( ges.

In testimony whereof' l alii); my signature in the presence of tvvo witnesses.
