BocKEmARM-sniir'r BEARING.

Specification of Letters Patent.

Patented Oct. 5. 1920.

Application filed August 25, 1919. Serial No. 519,548.

To of? whom it may concern Be it known that I, VViLLIAM W. Nintennoun, a citizen of the United States, residing at Spartanburg, in the county of Spartanburg and State of South Carolina, have invented new and useful Improvements in Roelrer-Arm-Shaft Bearings, of which the following is a specification.

In loom operation the rocker arm shaft oscillates and there is therefore a tendency for said shaft to wear unevenly or at one side thereof. with. the result that lost motion of the shaft is permitted in an up and down direction which is materially objectionalile because it gives rise to breakage of the threads in the battery of the loom.

The objeet of my present sole invention is the provision of an advantageous bearing that will preclude uneven wear of the rocker arm shaft, notwithstanding the oscillatory ehararter of the movements thereof.

The invention also contemplates the provision of a hearing having the capacity stated, and adapted to be adjusted in order to take up wear.

To the attainment of the foregoing. the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, hereby made a part hereof:

Figure 1 is an elevation showing the bear ing constituting the best practical embodiment of my invention of which I am rognizant, as properly arranged relative to a rocker arm shaft and the adjacent parts of a loom.

Fig. 2 is a vertical section of the same, with the shaft in elevation.

Fig. 3 is a section taken at right angles to Fig. 2. and in the plane indicated by the line 3-3 of said figure.

Fig. 4 is a section taken through the saddle block. and shaft in the plane indieated by the line 4-4 of Fig. 2.

Fig. is a face view of the boss and the plate by which the same is carried.

Fig. 6 is an end elevation of the saddle block.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

The loom frame portion 7 and the plate 9 equipped with the boss 10 and eonneeted at 8 to the frame portion, are of the ordinary well known construction, and the rocker Q arm shaft 11 is disposed in the boss 1 in the usual manner.

In the carrying out of my invention a saddle block 12 is made to straddle the shaft 11. The said block is equipped with three screws 18, which are relatively arranged shown, and are set against the shaft 11 so as to cause the saddle block to oseillate with the shaft. The said screws 18 are also for adjustment purposes to take up wear. and hence they may be properly denominated combined set and adjusting srrews. At i i the saddle block is provided with an ar-uate flange that overhan g s the boss and is spared therefrom and is provided at 13 w th retainers. In the spare afforded on the flange 13 and between the same and the opposed portion of the boss 10. I may employ antifriotion members 16 in the form of rollers or balls, or in lieu of said members I may oc upy the space with the sul'istai'iee well known on the marketas bakelite deleoto.

When my improvement is properly applied as illustrated. it will he observed that the weight of the shaft is transferred to the top of the bearing. and when wear takes pla e at the top of the hearing. such wear may be expeditiously and easily taken up hy an attendant by simply serewing the upper screws 17 downwardly and loosening to a (-orresnomling extent the lower screws 18. It will also he observed that the arrangement of the flange 13 above and in spaced relation to the hearing is materially advantageous. inasmuch as any dust or dirt that may find its way into the anti-fria-tion means employed will tend to gravitate away from such anti-friction means. and hence will not in any degree impair the usefulness thereof.

In addition to the praetieal advantages hereinbefore ascribed to my novel hearing, it will he noted that the hearing is susreptible of application to installations such as at present in use without entailing any change whatever in such installations and without the necessity of employing skilled labor or tools other than an ordinary wrench for the setting of the screws 18. From this it follows that the improvement may as readily be removed from a rocker arm shaft when oeoasion demands.

An important advantage that attends the adjustment of the saddle blo'rk relatively to the rocker arm shaft, lies in the fact that the said adjustment obviates any canting of the saddle block away from the frame portion 7. This is due to the fact that the vertical plane of the upper screw 17 is more remote u from the plane portion 7 than the vertical plane of the lower screws 18.

llaring described my invention, what I claim and desire to secure hy Letters-Patent, is:

i. lhe combination of a loom frame, a plate secured to said frame and having a boss, a rocker arm shaft journaled in said boss, a saddle block on the shaft beyond the boss and having an arch portion extending to the frame and disposed above and spaced from the boss, anti-friction means between the boss and said arch portion, lower screws in the saddle block and engaging the lower portion of the shaft at opposite sides of the vertical center thereof, and an upper screw engaging the central portion .of the shaft; the lower screws being nearer than the upper screw to the flange.

2. The combination of a loom frame, a plate secured to said frame and having a boss, a rocker arm shaft journaled in said boss, a saddle block arranged on the shaft beyond the boss and fixed to the shaft and having an arch portion extending to the frame and disposed above and spaced from the boss, and anti-friction means arranged between the boss and said arch portion and covered by the arrangement thereof relatively to the frame.

In testimony whereof T affix m nature.
