FRONT-ROLL STAND FGR SPINNING-FRAMES.
LWESPEB L Application filed Apri1'29, 1921.
To all whom it may concern:
Be it known that we, Don CARLOS LEONARD and ARCHIE PERRY GREEK, citizens of the United States, and residents of Greenville, in the county of Greenville and State of South Carolina, have invented certain new and useful Improvements in Front-Roll Stands for Spinning-Frames, of which the following is a specification.
Our invention relates to stands for front feed roller .of spinning and roving frames of cotton mills, and a purpose of our invention is the provision of a stand having a bearing which is adjustable to support the front feed roller in proper position to secure the proper tensioning of theyarn, and which is removably associated with the stand to permit substitution of a new bearing when it becomes unduly worn.
A difficulty heretofore entertained in all spinning and roving mechanisms has been the uneven drawing of the cotton yarn due to the improper adjustment of the front feed rollers which is caused by the bearingssupporting these rollers becoming worn due to the rapid speed with which they rotate. As the roller stands are now con structed it is necessary to discard the entire stand when the front roller bearing becomes worn. Our invention permits of the adjustment of the front roller bearing so as to absorb the wear of the bearing, and todetach the hearing from the stand when it becomes unduly worn so that a new bearing can be substituted. The mounting of the bearing upon the stand is such as to permit of both lateral and vertical adjustments which is necessary in order that the front feed roller be properly adjusted with respect to the other rollers.
We will describe one form of stand embodying our invention, and will then point out the novel features thereof in claims.
In the accompanying drawings:
Figure 1 is a view showing in side elevation one form of stand embodying our invention.
Fig. '2 is a top plan view of the stand shown inFig. 1. r
Fig. 3 is a perspective view of the stand shown in Fig. 1 with the front roller bearinn removed.
eferrin specifically to the drawings, in Which .simiar re erence characters refer to I Specification of Letters Patent.

Serial No. 465,437.
similar parts, our invention in its present embodiment comprises a base 15 upstanding from whlch 1 a' pedestal 16, and formed at the upper end of the pedestal is a'ledge 17 slotted to receive an adjusting screw 18 which extends into a bearing casting 19 for the reception of the intermediate and rear feed rollers as indicated in dash lines in Fig. 1. The lower end of the ledge is provided with an upstanding lip 20 which is adapted to coact with the front roller bearing 21 for supporting the front feed roller as indicated in dash lines. The bearing 21 is provided with a depending exten sion 22 slotted as indicated at 22 to receive an adjusting screw 23. The extension 22 is held against a flat face 16 of the pedestal 16 by means of the screw 23, the latter threadedly engaging the pedestal in the manner shown, and provided with a washer 23 for permitting rotation of the screw whenwithin the slot. At the lower end of the flat face 16, the pedestal 16 is provided with a projection 24: in which is threadedly fitted a set screw 25 carrying a ,nut 26 for locking the set screw in adjusted position. The upper end of the set screw 25 is adapted to engage the lowerend of the extension 22, it being particularly noted that the lower end of the extension 22 is rounded for a purpose which will be hereinafter described.
The bearing casting 19 and the ledge 17 together with the adjusting means for the casting are all parts of a standard form of stand andtherefore form no part of the present invention. The front roller bearing 21 in the stands heretofore used is cast integral with the pedestal 16 so that it is incapable of adjustment and obviously cannot be removed from the stand.
In the operation of our invention the bearing 21 is capable of being adjusted vertically by virtue of the screw 23 engaging the pedestal and extending through the slot 22 of the extension 22. Horizontal adjustment or more strictly speaking the lateral adjustment of the bearing about the screw 23 as an axis can be effected by loosening the screw 23, turning the bearing in one direction or the other, and then moving the screw 25 so as to firmly engage the rounded end of vand it is to be particularly noted that irrespective of this lateral adjustment the screw 25 will properly contact with the extension 22 by virtue of its rounded end. The screw 25 also cooperates with the screw 23 in retaining the bearing in vertically adjusted position, and by virtue of these two adjust-,
over the rollers. When the beariflg 21 becomes so worn that the adjusting means cannot maintain the bearing in proper position to support the roller, the bearing is removed and a new one substituted thus eliminating the discarding of the stand as a whole.
Althoughwe have herein shown and described only one form of stand embodying our invention, it is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention or the spirit and scope of the appended claims.
What we claim is:
1. A stand for spinning or roving frames comprising, a pedestal, a projection formed on the pedestal, a front roller bearing formed independently of the other bearings, a slotted extension formed on the bearing, a screw extending through said slot and threadedly engaging the pedestal at a point above said projection to permit of effecting a horizontal adjustment of the bearing, and a second screw adjustably fitted within said projection and engageable with said extension to effect a' vertical adjusting of the bearing.
2. A stand for spinning or-roving' frames comprising a pedestal having a flat face, a projection formed on the pedestal at the lower-end of the fiat face, a screw extending through said projection, a front roller bearing contacting with the flat face, a slotted extension formed on the bearing, ascrew threadedly engaging the pedestal and extending through said slot, the lower end or said extension being rounded and adapted to be engaged by the first screw, for the purpose described.
3. A stand for spinning or roving frames comprising a pedestal, a front roller bearing movable on the pedestal independently of the other bearings, means for adjusting the bearing horizontally and separate means for adjusting the bearing vertically.
4. A stand for spinning or roving frames comprising a pedestal, a front roller bearing movable on the pedestal independently of the other bearings, means for adjusting the bearing vertically, and separate means for adjusting the bearing horizontally and irrespective of its vertical adjustment.
5. A stand for spinning or roving frames comprising apedestal, a front roller bearing 7 movable on the pedestal independently of the other bearings, means for adjusting the bearing horizontally, and separate means for adjusting the bearing vertically, said means cooperating with each other to permit of the adjustment of the'loearing about the transverse axis.
