' LUBEICATING SYSTEM.

for lubricating shafts and particularly those vertically disposed andyincluding a foot-step bearing, as for instance the side-head spindle of wood, yEvorking machines in whichy latter connection the invention isl herein 15 illustrated although by no meansl limited to such application. By reason of the fact that the invention is capable of embodiment in varied constructional forms and in different relations the accompanying drawing and detailed `description based thereon are to be taken in an illustrative and not in an unnecessarily limiting sense.

In the' drawing-Figure 1 is a vertical section through shaft bearings illustrating the invention; and Figs. v2 and 3 are horizontal sections on thelines 2-2 and 3 3 `re' spectively.

In the embodiment chosen for purposes of illustration the machine frame 11 has fulcrumed in its lower portion at 12 a lever 13 the opposite end of the lever arm having threaded engagement at 14 with I a screw spindle 15 loosely traversing the bracket 16 rigidly attached to the machine frame. The

screw spindle is encircled by the spring 17' disposed between the lever 13 and the bracket 16 and bearing downwardly upon one and upwardly upon the other. A nut 18 enagagesthe spindleabove the bracket and is frictionally held by the spring detent 1 9. By the lever 13 between its fulcrum 12 and its connection at 14 with the screw spindle is supported an oil well casing or box 20l provided with a sight gage 21 and a T-connection 22 through which latter the oil may be drained fromd the casing when desired. A cover for the 'casing is represented at 23 which is removable for the purpose of replenishing the oil well within the casing.

An inner wall 20a forming the false bottomof the oil well has a central recess 24 within which is seated the stud 25 on the lower l face of a foot step block 26 having an upper flat face, the block being retainedbetween the side wallsof an upper larger recess 27.

AppIication led September 20, 1915. Serial No. 51,539.

The recess 27 and the block 26 are shown as of substantially circular cross section with the exception that on one side the block and recess are provided with coperating projecting port-ions 26EL and 27i in order to bring about a relative engagement to prevent rotpation of the block while permitting the same to rock freely Within the recesses' 2l and 27. The supporting wall 20a and the foot-step block 26 have central bores 28 and 29 respectively which are `in register with each other in order to afford a channel through said wall and block for the oil.

Seated at its lower end upon4 block 26 is the vertical shaft or spindle 30 having a short distance above its lower end an annu! lar recess 31 for the reception of a sectional washer 32 which may be of the same metal as the foot-step block 26 and preferably brass. This washer 32 is contained within the lower end of a threaded sleeve 33 and bears upwardly against a flange 33a of said p sleeve. The sleeve 33 is screw threaded within the upper portion of the oil well vcasing and serves to confine they shaft to a limited vertical movement by means of the engagement of thewasher 32 within the annular recess 31.

It will be observed that the position of the shaft is vertically adjustable by means of the screw spindle 15 acting upon the free end of the lever 13- and that vertical vibrationof the shaft is absorbed by the spring 17 acting upon the lever 13 and the bracket 16 of the machine frame. c

-Within the machine frame is mounted above the oil wellcasing a box 34 providing a journal bearing forthe shaft, the babbitted portion 35 ofthe bearing having on one side a longitudinal groove 36 closed below and upon the opposite side a longitudinal` groove 37 open below 'at a point above the oil well. Communication is established between the grooves 36 and 37 at the upper end of the journal bearing by an annular groove 38, it being noted in passing that the groove 37 has a cross sectional area substantially twice that of the groove 36 for a purpose which will hereafter be made apparent. The lower end of the shaft is provided with a bore 39 which coincides with the axis of thepshaft at the lower terminus thereof and thence extends upwardly at an angle 'tothe axis of the shaft and at'lO has a port opening to the shaft perlphery at a lao journal box.

the bores 28 and 29 and as the shaft rotates the oil willbe fed upwardly by centrifugal action through the bore 33 and its outlet 40 into the groove 36 and alsoI to the groove 37 as the port registers alternately with said grooves. The oil introduced to the groove 40 is forced by the incoming oilupwardly to the annular groove 38 and thence passes through the groove 37 whence it flows downwardly through the open lower end of the groove 37 and discharges into the oil well.

Above the journal bearingl 34 and beyond the vdrive pulley 41 is arranged another journalbearing 42 the babbitted portion 43 of which has at one side a. longitudinal groove 44 for the accommodation of the lubricating member 45 here represented as a. wick the outer cud of which dips within a body of oil 46 the oil being conveyed upon the rotation of the shaft by said wick from `the oil well and serving to lubricate the upper portion of the-shaft.

The alinementof the shaft and its journal box is provided forby means of a plurality of screws, herein shown as three in number, engaging the machine frame and journal bearings, certain of the screws arranged to force the journal bea-ringin one direction and certain others to force it -in the opposite direction whereby the same may be adjusted and firmly positioned. These screws arcadvantageously arranged in line longitudinally of the shaft and referring to the upper bearing 42 the screws 47 are threaded inthe machine frame and bear inwardly against the journal box 42 while the intermediate screw 48 is threaded in the journal box and bears upon the frame. In the lower journal bearing 34 the conditions are reversed without change ofv function, the upper and lower screws 49 having threaded engagement with the journal box while the screw 50 has lthreaded engagement with the machine frame and bears inwardly upon the I claim:
