SHAFT ADJUSTMENT.

Application filed July 5, 1923.

To all whom it may concern:

Be it known that 1, WILLIAM L. PAUL, a citizen of the United States, residing at Berkeley, in the county of Alameda and State of California, have invented certain new and useful Improvements in Shaft Adjustments, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to bearings for shafts or the like, and my object is to construct a device of such type having features of ad j ustment by the operation of which a shaft can be quickly alined.

Referring to the drawings in which similar numerals indicate identical parts Figure 1 is a side elevation of a shaft and bearing illustrating the application of my device. Figure 2 is an end vew in part section on the line 22 of Figure 1, and Figure 3 is a section on the line 33 of Figure 2.

Secured to a support 1 in any suitable manner is a pedestal bearing 2, the upr1ght part, in which a shaft 4 is journaled, has a flange 5 projecting from one side of the part 3 to give a more extended bearing surface, and from the opposite side of the part 3 1s a similar flange 6 in which is provided a series of equidistant notches 7. A sleeve 8 is mounted eccentrically on the shaft 4 and extends through a similar eccentric sleeve rotatably journaled in the orifice in the part 3, and with the parts stated forms the bearing for the shaft 4:. The eccentric has formed on one side of its periphery teeth 10 which are adapted to fit snugly 1n the notches 7, and on the opposite side is aseries of notches 11 in which engage teeth 12 formed on the eccentric 8.

To counteract end thrust of the shaft 4 a collar 13 is fastened on the shaft by a set screw 14 and contacts with the adjacent end of the eccentric 8. It is understood that a similar bearing, provided with like adjusting devices, supports the other end of the shaft, and that other means may be employed to resist the end thrust.

Assuming that the shaft 4 is out of alinement and the parts in position as shown in Figure 2, I loosen the set screw 14 so that the collar 13 may be moved away from eccentric 8 to permit disengagement of the teeth 12 thereon with the notches 11 of the eccentric 9; the eccentric 8 is now freely turnable to adjust the shaft a either lateral- Serial No. 649,471.

ly or vertically, but it is evident that no true vertical adjustment can be made without, at the same time, moving the shaft laterally and it is also noted no lateral adjustment by operation of the eccentric 8 alone can be effected without moving the shaft vertically.

To overcome the dual movement of the shaft f when the eccentric 8 alone is operated, the eccentric 9 is freed from its engagement with. the notches in the flange 6 of the part 3 until it is independently turn able. Now, as before stated, rotation of the eccentric 8 either to right or left when it is desired to aline the shaft 4 willresult in a vertical as well as a lateral movement and to overcome this dual movement the eccentric 9 is rotated simultaneously and in the same direction and at a speed sufficient to retain the movement of the shaft 4: in a line radial to its axis, and when the desired adjustment has been made the eccentrics can be again interlocked and the collar 13 be secured in place.

It will be apparent that by rotation of the eccentrics 8 and 9 they can be adjusted in varying positions relative to each other, and by their operation, irrespective of their relative position, the adjustment of the shaft 4 is accomplished in a more accurate manner, the line of adjustment being radial to the axis of the shaft, the fineness of adjustment depending upon the number of teeth and notches in the interlocking parts.

What I claim is 1. A shaft bearing, a shaft supported therein, sleeves on the shaft and in the bear- 111g, one sleeve within the other eccentric to 'each other and to the shaft and rotatable to adjust the shaft in varying directions radial to its axis, means on the sleeves integral therewith and interlocking to hold said sleeves from independent rotation, and means on the bearing integral therewith and interlocking with means on one of said sleeves to hold the latter from rotation after the shaft is adjusted.

2. A shaft bearing, a shaft supported therein, sleev on the shaft and in the hearing, one sleeve within the other eccentric to each other and to the shaft and independently and jointly rotatable to adjust the shaft in varying directions radial to its axis, means on one sleeve integral therewith and interlocking with means integral with the other sleeve to hold said sleeves from independent rotation, and similar means on one of said sleeves and on the bearing interlockin to retain said sleeves in position after the shaft is adjusted.

' 3. A shaft bearing, a shaft supported therein, sleeves on the shaft and in the hearing, one sleeve within the other andeceentric to each other and to the shaft and independently rotatable to adjust the shaft in varying directions radial to its axis, means integral with one sleeve interlocking with means integral with the other sleeve to hold said sleeves from independent rotation, similar means on one of said sleeves and on the bearing and integral therewith cooperating to retain said sleeves in position after the shaft is adjusted, and a collar on said shaft operating to prevent movement of said sleeves longitudinally of the shaft.

4. A shaft bearing, a shaft supported therein,'sleeves on the shaft and in the hearing, one sleeve Within the other eccentric to each other and to the shaft and independently and jointly rotatable to adjust the shaft in varying directions radial to its axis, a flange extending from one side of said bearing and having notches, a flange on the outer sleeve having teeth to engage with the notches on the bearing, teeth on the sleeve flange opposite the notches therein, a flange on the inner sleeve having teeth to engage with the notches in the flange of the outer sleeve, arcollar on the shaft, and a set screw operating to secure the collar on the shaft whereby the said sleeves are held from longitudinalmovement on the shaft.
