SHAFT- BEARING.

SPEGIFICATION forming part of Letters To (1.71 1H1 0m it may concern.-

Be it known that I, ADoLPH HAENICHEN, a citizen of the United States, residing at corner Prospect street, in the city of of Broadway and Paterson, county of Passaic, and State of New Jersey, have invented certain new and useful Improvements in Shaft-Bearings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make andnse the same, reference being had to the accompanying drawings, on, which form a part of this specification.

.This invention relates to mountings for revoluble shafting, and it has reference particularly to mountings and described in my copending application for Jnited States Letters Patent, filed February 29, 1900, Serial No.3,083.

One object of the invention is to so mount a shaft of the nature above indicated that the production of friction will be reduced to the minimum and the hearing be as simple and durable as possible.

A further object of the invention is to no construct and arrange the bearings for a vertical shaft such as that shown-and described in my copendingapplication forUnited States Letters Patent for a spinning-machine, filed January 29, 1900, Serial No. 3,083, that the shaft may with facility be removed when occasion requires.

A still further object of the invention is to.

so construct a bearing designedto counteract the tendency of a'shaft toward longitudinal movement that the parts thereof may be selfnotwithst'anding uneven wear or the fact that the shaft is not disposed perfectly perpendicular with'reference tosaid bearing.- V

The invention consists in the improved mountings for revoluble shafting and in the combination and arrangement of the various parts-thereof, substantially as will be hereinafter pointed out and finally embodied in the clauses ofthe claim.

Referring to the accompanying drawings, Figure 1 is a view in side elevation of the end portion of a spinning-machine, showing Application filed March 21, 1900. Serial No. 9,497.

and to letters of reference marked therefor the'shafts of aspin cling-machine substantially like that shown Patent No. 664,946, dated January 1, 1901.

(No model.)

certain revoluble shafts and-the mountings therefor. Fig. 2 is an enlarged view, in side elevation, of a vertical shaft and its mountings, the latter being shown partly in section. Fig. 3 is a view in front elevation of the upper mounting for said vertical shaft; and Fig. 4 is a view of a portion of a horizontal shaft and one of its mountings, the latter being partly shown in section.

In the accompanying d rawings,(.l. designates the frame of a spinning-machine, while I) dening-machine and adapted to deliver thread ontobobbins which may be arranged in brackets c and are adapted to bedriven by rollers (I, mounted on horizontal shafts e, which are jonrnaled in the frame. f denotes a vertical 11mm ublc shaft carrying sheaves g, over which extend he s-.12.. that bear against the whirls i of said spindles, so as to rotate thelatter. j design-ates a system of gearing operatively connecting each shaft 6 with a worm is on said vertical shaft.

'l and m are the pedestals for supporting the vertical shaft f. Each of these pedestals consists of a plate n, having a pair of alined ver- 1 tical slots 0, adapted to receive the bolts for securing the pedestals to the end upright of the frame a. Since the slots extend vertically in each plate, the pedestal is rendered vertically adjustable when the bolts are loosened. 'lhe pedestal l, which constitutes the step-bearing for said shaft, has a socket 1'), adapted to receive the lower end of the shaft f, and in the top surface of said pedes tal is formed around the socket an annular channel q, inwhich are arranged antifriction-balls 1-. Upon the shaft f is secured a collar 5, said collar being rigidly secured in position by means of a feather-and-key arrangement t. Between said collar and the pedestal and washer u. lhis washer is of glass-hard steel. By virtue of this provision a bearing of the maximum durability is produced.

The'pedestal of constituting the bracket and having the slots 0 above described and the other part w being the upper socket or pedestal proper for the shaft. The two parts have pairs of projections m, which are penetrated by bolts y notes spindles rcvolubly mounted in said spin m is divided, one part 1; there for securing said parts together. The part to is provided with a socket z, the same as thesocket p of the lower pedestal, with the exception that it is somewhat larger. In this socket is arranged a cup-bushingor thimble 1, directly receiving the end of the shaft. This thimble is adaptedto be properly set by a screw 2, mounted in the top of the pedestal andadapted to bear against the top of the thimble. V

By arranging the pedestals so as to be vertically adjustable the shaft f may be removed without -entirely removing either pedestal from the frame and without appreciable longitudinal movement of the shaft. The sheaves do not have to be loosened, as they would have to be if the shaft were removed longitudinally, for the reason that they project into more or less confined openings in the upthe shaft Into each pedestal or plumber-block 4 for the shaft 3 is screwed an annular bushing 9, which is penetrated by the shaft 3, the adjacent interior edges of said bushing and the plumber-block being chamfered 'olf to form a ball-race. 10, in which are arranged about the shaft antifriction balls 11. Upon the shaft and between and close to the plumberblocks are secured collars 12. These collars are fixed adjustably by means of binding screws 13. The face 'of each pedestal or plumber-block adjacent the adjoining collar is provided with an an'nularball-race 14, in which is arranged another set of autifrictionballs 15. Against each set of these balls is adapted to bear a glass-hard steel washer 16, corresponding to the washer u, said washer being interposed between the pedestal and the collar and acting, when the collar is properly secured in place, to keep the balls in their groove. Each 'glasshard washer 16 serves the same function as does the corresponding washer u for the vertical shaft.-- v

The reason for providing the collars 12 and the bearings disposed between them and the plumber-blocks grows out of the fact that the worm-and-worm-wheel connection between the shaftsfand 3 tends to impart a longitudinal thrust to saidshaft 3, as indicated by.

the arrow in Fig. 4 Ofcourse it depends upon the direction-"in which the machine is working as to whether the shaft f will tend to be moved in the one or the other direction longitudinally.

dicated by the reference character 17 in the figure mentioned, having its fiat surface resting upon the balls 7', while the curved portion of its surface sits in a correspondinglyshaped recess 18, formed in the collar 8. The edges of the opening 19 in this washer may be rounded off, so that the shaft cannot possibly interfere with the action of said washer.

It will be observed that by virtue of this construction whatever the position with referalways self-adjusting, so as to work perfectly true. i

Since I usually secure the upper pedestal to a cross-bar 20 of the upright, which has strengthening-flanges 21, between which the part '0 of said pedestal is bolted, it is in order that the shaft f may be readily removed notwithstanding the fact that the up'per one of these flanges and the worm 8 coact to prevent dismounting the shaft that I divide the upper pedestal. Said pedestal being made in two parts, upon removing the bolts securing them the shaft f may be lifted till the Worm and worm-wheel clear each other, and then it canbe removed without interfering with any other parts.

Having thus fullydescribed my invention,

what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a frame, of a vertical shaft, pedestals disposed the one above the other, said lower pedestal being adjust ably secured to the frame and receiving the lower end of said shaft, a collar fixed on said shaft, a'hardened washer penetrated by said shaft, a ball-race in the lower pedestal and surrounding the shaft, balls arranged in said ball-race, said washer being interposed between the collar and the balls, and said upper pedestal comprising a socket portion and a bracket portion having projections, and bolts penetrating said projections to secure said socket and bracket portions toge her, saidsocket portion receiving the upper end of said shaft and said bracket portion being adjustably secured to the frame, snbstaa tially as described.
