SUPPORTING MEANS non SPINDLES IN srinnine MACHINES AND THE LIKE.

This invention has reference to supporting means for the spindles of slubbing, roving, spinning, twisting and similar machines, and .it refers in particular to a novel construction of the supporting or journaling beam for the reception and journaling of a plurality of spindles of the kind mentioned, and among other objects and advantages the invention makes provision for a better lubrication of the spindles and to generally improve the j ournaling and mounting of the same. In the slubbing, roving, spinning and twisting machines, as heretoforeconstructed the journals of the spinning spindles which were commonskew wheels, were arranged inseparate'boxes or casings in such a manner that each spindle was provided with a journaling box of its own and which was securedto the supporting beam. It has already been suggested heretofore to mount all the different journaling and supporting members in a sheet metal boi; in

which the operating shaft with the supporting means for the worm wheels was arranged, and in which the rods for the raising of the ring bealnhad to be mounted by means of special additional bearing and retaining members. With these previous arrangements there was the inconvenience that the exactness of adjustment of the entire supporting means was interfered with, and on the other hand there was but very imperfect irro tection against the escape ofv oil and the entrance of impurities; nor was the lubrica- 'tion of the spindles and of the gear wheels satisfactory.

Vith a view of'overcoming these drawbacks the supporting beam in accordance with my invention constitutes a closed casing for a plurality of spinning spindles and provided with a continuous depression for the reception of the bottom journals of the several spindles and filled with oil, so as to provide for a very perfect lubrication and for an exact gearing of the spindles. Theboi: shaped beam is preferably constructed so as said bearings being arranged and adjusted in such a manner as toprevent the escape of oil from the casing to the outside. The means for the raising of the lifting rods ofthe ring beam passthrough the casing in such a manner as to'be out of contact with the lubricatporting ly operated by means ofworm wheels or to serve at the same time as a means of mountmg the bearings for the driving shaft, the 6 ing space. In accordance therewith the sup and ournalingbeam is so arranged Application filed December 8, 1923, Serial No. 679,479, and in Germany Ju1y,14, 1923.':

and constructed that the fastening means for the several parts do not project outwards through the bottom portion, while on the other hand the beam serves asa carrier in common to all hearings or journals or of other means which are directly supported or guided in the box-shaped beam without any additional supporting members.

An embodiment of the principles of my invention is shown by wayof example on the accompanying'drawing in which Figure 1 is a transverse sectional view through the boxshaped beam, and FigureQ' is a horizontal section through the same." I

y The supporting beam comprises a U-shaped I casting 1 theopcn side of which may be closed bya slide or by a glass plate 2 tightly secured thereto by screws or otherwise. I i

di ithin the housing 1 a plurality of spindles 3fis supported by lower ball bearings 4 and upper ball bearings 5. The bearings 5 are transversely held by springs 19 arranged in a casing which comprises a collar 7 atheight ofthe depression 8, so that the gear- Iingof the spindle isonly very little immersed into theoil, while when running the spindle aropels the oil upto the gearingof the worm wheel orthe like 10. T he'bearings 11 for the shaftlQ of the wheels 10 should be carefully adjusted, inorder to produce smooth running of the machine With this end in view the bearings are supported by screw threaded studs 13 by the intermediary ofv a groove 14, the bearing being forced against the stud by the drip-lubricator 15. It is of importance in" this connection that the holes 16 for the reception oft-he stud 13 in the casing 1 do not extend through the walls of the casing, as otherwisethere would be an impossibility of'tightening the casing against leakage of oil.

The so. called poker rods 17 on which the usual ring'rail is mounted Which carries a spinning ring for its spindle are guided in; laterallugs'lS of the wall of the housing]. so as to preclude any contact of the rods with the lubricant being within the lubricating channel. These ringrailsare well known to those familiar with the art and have thereof not been illustrated in the drawing. The invention has been described in its broad aspectsand a plurality o1 spaced lubricant cavities communicating therewith at their upper ends,

a'plurality of spindles supported in and by the said casing, actuating WOEIHS on the said spindles extending into thesaid lubricant channel and being adapted to lift lubricant therefrom upon lJeing rotated, aplurality of worm gears engaging with the spindle actuating Worins at a point supplied With lubricant from the said channel by and upon rotation of the said spindles and being aii'anged at sucha level as to be out of contact with the lubricant that may he on the said bottoinwall, a supporting and actuating shaft for the said wvoi'in ears ii men resilient beaiings'for the t 7 L h saidspindies an lower spindle hearings at the unctions of the said lubricant channei end the said lubricant cavities substantially as for the purpose described.
