A To al?, :hom it may concern,.-

Be it known that I, Jenn L. WILLIAMS, a

.citizen of the United States, residing, in thecity and county, of Philadelphia, State 'of Peimsylvania, have invented a new `and useful Self-Adj ust able Journ al, Crank, and Axle- Bearing, o`f which the following is a specification.

My invention consists of a novel construction of sell-adjustable journalor crank bearing in which the shaft will not bind or stick in case the bearing becomes heated and expands, and is especially adapted 'for use with shafts which revolve at a high rate ol speed.

lt further consists in the interposition between the movable parts of the 4box of a bearing of a Wedge-shaped sliding key adapted to lic upon the obliquefaoe or the movable part of said bearing and provided with a suitable spring whereby the sliding key is constantly forced forward asthe journal or axle Wears away the contiguous face of the bearing, thus causing the boxes to always have substantially the same relation to the shaft mounted therein.

It irther consists in the employment of a' 'fibrous Washer between the heads ot the bolts and the adjacent portions of the cap, said cap being suitably recessed, so that a lush joint is Jformed.

lt further consists in means 'for preventing forth.

Figure 1 represents a sectional elevation of an adjustable bearing embodying my inventionA Fig. 2 represents e sectional elevation of another embodiment 'thereof in which two wedge-shaped sliding keys are employed. Fig. represents a plan view of one of the springs in detached position. Fig. 4 represents side elevation of Fig. i

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates a connecting-rod to which the. pillow-block 2 is suitabl; secured, tlie same being integral therewith, ill desired.

3 designates upwardly-extending sides, through which ypass the bolts 4, provided with suitable nuts.

6 designa-tes a cap which is provided with recesses 7, within which are contained the -librous washers 8, between which and the heads ot the bolts 4 are metal washers 9.

i l i l l l l .the inclined facerll or the movable bearing 10 and 1s .provided with a flange 13, whereby said key is retained in place. 14 designates a chamber or recess extending into said key 12, in which is inserted the spring 15, one end of said spring engaging one end of said recess and the other end of said spring engaging the inner wall o1" the side rlhe spring 15 always tends to move the sliding keiT 12 fon wardly or to the right, as seen in Fig. 1, so

that as the bearingP material of the bones Wears away the said boxes will always have the same relation to the shaft, owing to the spring 15 forcing the key 12 forwardly, and thus-moving the movable bearing 10 downwardly 'against said shaft.

16 designates a lug or projection extending from the connecting-rod`1, which prevents any improper movement of the lower box 2.

In' the embodiment seen -in Fig. 3, 1.6 designates a connectingaod provided with a lu 17,.'vhich engages the pillow-block 1S an prevents improper movement thereof, said block 18 being provided with the upwardlyextending sides 19, tlirougl'i which pass the bolts or 'rods S20, provided 1with suitable nuts 21 and by means of which the cap 22, pillowblock 1S, and the connecting-rod are secured together.

23 designates a recess in the cap which is metal Washer 25, said recess being;- of such depth that the metal washer is llush withthe surface of the cap when they parts are in assembled position.

2G designates the upper movable bearing, which is provided with a suitable flange 27, whereby it is retained in position.

28 designates a sliding key which is Wedgeshaped and provided with a flange 29, which l the inclined face othe Wedge 28. `This key is in placed a fibrous washer 24 and a` IOO and said sides, nuts for said bolts, and resiliently-actuated means interposed between said cap and said bearing for automatically takin up the Wear of said bearings.

5. n a journal-bearing, a fixed bearingblock having sides extending therefrom, a'eap yieldingly secured to said sides, a bearingblock movable between said sides, keys interposed between said movable bearing-block and said cap=and each having an. inclined face coasting with the inclined face of another key, springs adapted to automatically advance said keys in o posite directions, a spring secured on the p ane face of each key, t ere being teeth on the contiguous face of said cap -and said movable bearing-block with which said springs enga e to prevent any rearward movement of sai keys.

6. In a device of the character described, a bearing-block having sides extending there from, a bearing-block movable between said sides, a cap yieldingly secured to said sides,

keys, each having an inclinediace coacting' with the inclined face of another key and interposed between saidca and said movable bearing-block, and provi ed With a recess on its plane face, springs for advancing said keys in opposite directions, =a s ring secured in each of said recesses, there eing a plurality oi armsof diierent. lengths extending from said last-mention@` springs and teeth on said cap and movable ybearing-block conti uousv said 'recesses with which one or more o saidv arms engage to prevent rearward movement of said keys.

7. In a device ofthe character desir/filled, a

connecting-rod, a fixed bearing-block havy ing integral extending sides connected there-A with, means for preventing the im roper movement ofsaid iixed bearing-bloei with respect to said rod, a cap yieldin ly secured to said sides, a movable bearing-b ock guided between said sides and having flanges which prevent improper lateral movement ot said movable block, kes interposed between said movable bearinglock and said cap, each having an inclined face coasting with the inclined face of another key and springs adapted to automatically advance said keys in opposite direct.
