FRIEDRICH MITNZ, F STUTTGART, GERMANY.
sr'rrinme srrrmnn To all whom it may concern.
Be it known that I, FRIEDRICH MiiNz, re-
siding at Stuttgar t, Blumenstrasse 27, Germany, have invented certain new and useful Improvements in Spinning Spindles (for which I have filed an application in Germany Feb. 12, 1919-), of which the following is a specification.
The present invention relates to spindles with ball bearings and guishing-feature of the invention is spinning a distinthat only a single ball bearing is used between the spindle and the tubular body thereof, the
bearing pulley. that the being surrounded by the driving Another feature of the invention is bottom end of the spindle is pointed and rests in an open cone-shaped cavity or seat formed in the upper end of a swinging support or prop normally held vertical by laterally disposed support being such that springs, the length of the is deflected no gap or play'is produced be neath the.seat and the bearing end of the spindle. An advantage rangement is that the gained by this arbottom end of the spindle may deflect freely in all directions without giving rise to jamming of the supporting bearing, and besides smooth running of the spindle is obtained because the swinging support keeps the spindle securely propped up no matter what position it might swing into.
Instead of lubricating the spindle with grease a circulatingoil lubrication may be provided.
Provision is made for acirculating oil lubrication accord ing to the invention by arranging the swinging support and its springs inside a p erforated threaded cylindrical shell or barrel, which, by means of its thread and a threaded ring can be precisely set with re spindle, and over spect to the end of the .which an outside shell is pushed which serves as an oil reservoir.
By'this-arrangement the oil is caused to, enter through theholes of the first mentioned to Wash around the end of the shell and spindle so that it permanently immersed in and the step bearing are oil. The spindle i tapers from the position where its ball bearing is situated down to its bottom end and the rapid rotation of the conical spindle gives rise to a sucking action which causes the oil at the bott om end of the spindle to when the spindle Renewed March 3, 1922.

climb up to point of maximum diameter of the spindle, i. e.,* up to the ball bearing, which is thus copiously lubricated. From the ball bearing the oil creeps along the inneiwalls of the spindle body and back into the shell. Any particles of oil that might pass up beyond the ball bearingmay be caught up and returned to the ball hearing by some suitable device such as an annular cup formed around the spindle by a ring-shaped exten sion, so that no oil is lost and a permanent lubrication is secured. The same effect may also be obtained when the swinging support is suspended instead of being stood up on end. The suspended arrangement comes into consideration when the space at the support and a circulating oil lubrication and Fig. 4 represents the third constructional form with a circulating oil lubrication and a hanging swinging support.
Referring to Fig. 1 a ball race is ground into the tempered spindle b at the height of the driving pulley c of the whirl of. The balls is are kept in position by an outer ball bearing ring m which is held in turn by a ring n, in the upper end of the tubular body of the spindle. The lower end e of the Spindle b which tapers down to a point is borne in a conical bearing cup f held up by a swinging support or prop g. The prop is kept in its middle position by lateral springs 71. arranged in opposed openings in the barrel and its lower pointed endis seated in a cup formed in a threaded bushlng z, mounted in the lower end of the splndle body. By means of the threaded bushing 71 the swinging support 9 can be raised or lowered in the proper position .With respect to the end 6 of the spindle. The socket receiving the spindle is of sufficient depth to retain the said spindle therein at all times. Hence no gap can be formed being winding, thereby securing smooth and uniform running. "lhe threaded bushing is preferably made in the form of a Staufler lubricator.
As shown in Fig. 3 the swinging prop g and its springs h are arranged in a perforated threaded sleeve or barrel 0 which is closed at the bottom and whose position relative to the end of the spindle e may be precisely adjusted by means of the thread 1/ and the threaded ring g.- 1" is an outside shell or oil reservoir which is slipped over the sleeve 0 and provided with a thread or any fastening or sealing means which en-v ables the reservoir to be easily detached. f is the step bearing, 8 the body of the spindle and 7c the ball bearing. The spindle body 3 is provided with a ring-shaped extension t that forms a small annular cup to in which any particles of oil are caught up that might rise above the ball bearing.
In the modification shewn in Fig. 4 the swingin support 9 is suspended, the upper part 0 the suspension member being formed in the shape of a ball surface that is seated in the upper part of the sleeve 0. This sleeve 0 is also arranged to be adjusted with respect to the end e of the spindle by means of the thread p and the threaded rin g.
It will be obvious that many changes and modifications can be made without departing from the scope and. spirit of the invention.
I claim:
1. In a spinning device, in combination with a stationary tubular body, a ball bearing mounted in the upper end thereof, a defiectable spindle arranged through the body and contacting with the bearing approximately medially of its height, a supporting prop having a bearing cup in its upper end for receiving the lower end of the spindle, a threaded perforated barrel supporting the prop and adjustably connected to the lower end of the body so as to support the prop with respect to the body and the spindle, laterally disposed springs within the barrel for normally holding the prop in a vertical position, and an oil reservoir associated with the perforated barrel.
2. The combination with a spinning device of an oil reservoir, a threaded perforated barrel arranged in the said oil reser voir, a support in the said barrel, lateral springs holding the said support, a bearing cup in the said support, a defiectable vertical spindle with its bottom end resting in the said bearing cup, a driving pulley attached to the said spindle, a ball bearing arranged approximately mid-height the spindle and surrounded by the driving pulley, a hollow body arranged around the said spindle and provided with a thread into which the thread of the said perforated barrel is screwed, whereby the position of the bearing cup relative to the bottom end of the spindle may be adjusted, and a ringshaped extension on the hollow body reaching up beyond the ball'bearing so as to form an annular oil cup.
In testimony whereof I afiix my signature.
