EUGENE R. ALDERMAN, OF HO'LYOKE, MASSACHUSETTS, ASSIGNOR T0 FARR ALPACA HOLDDOWN DEVICE FOR SPINNING FRAMES.
Application filed March 5, 1924. Serial No. 697,043.
To all whom it may concern:
Be it known that I, EUGENE R. ALBER- MAN, a citizen of the United States, residing at Holyoke, in the county of I-Iampden and State of Massachusetts, have invented new and useful Improvements in Holddown Devices for Spinning Frames, of which the following is a specification.
This invention relates to improvements in spinning frames but particularly to hold down devices for holding down the revolvable whorls of such frames to prevent a relative separating movement of the whorls and lifter rail.
Ordinarily, the whorls of spinning frames are rotatably carried by reciprocable spindles and are driven by bands or belts. The whorls carry the bobbins that are to receive the spun yarn and rest upon a lifter rail or plate. The spindles are usually fixed in a lower rail and pass through the lifter plate and whorls. In the dotting operation of the spinning frame the spindles are necessarily reciprocated up and down through the whorl and plate as explained in my Patent No. He. 15,604 of May 15, 1923. In one step of the dofling operation the full bobbins are held from a descending movement while the lifter plate is lowered to allow the whorls to be drawn downwardly therefrom to remove the bobbins from the whorls. Where the relative sizes of the whorl tube and bobbin opening are such as to cause the bobbin to stick to the whorl, the lowering of the plate does not of itself pull the whorl from within the bobbin. Accordingly, I provide a device carried by the plate that is adapted to engage a whorl should it stick within the bobbin and positively move the whorl downwardly with the plate.
Another step in the dotting operation concerned with my invention is when the spindles are raised through the lifter plate and whorl to elevate the cap to the cap-holding means. A sticking action of the whorl and spindle in this case will then tend to raise the whorl from the lifter plate but the device contemplated by my invention is so constructed and arranged as to engage the whorl to prevent it moving upwardly from the plate.
The embodiment of my invention will now be described in the form at present preferred, the same being illustrated in the accompanying drawings, in which:
Fig. 1 is a plan view of the lifter plate of a spmning frame showing a plurality of whorls having my holddown device associated therewith;
Fig. 2 is a cross sectional elevational View taken on the line 22 of Fig. 1; and
Fig. 3 is an isometric view at a smaller scale of my improved holddown device.
The device is applicable to all spinning frames but for the purposes of disclosure 1s shown as applied to the ordinary cap spinnmg frame. Such a frame usually includes a longitudinal lifter plate R that receives a plurality of sliding spindles S that support spinning caps (not shown). The spindles are usually fixed in a movable longitu dinal member located below the lifter plate that is moved up and down during the doifn g operation of the frame. This mechanism is not a part of the present invention but is referred to merely for the purpose of explaining that the spindles S are necessarily moved up and down through the rail R and whorls, which movement tends to move the whorls upwardly from the plate if there is a tendency for the spindle to stick within the whorls.
Whorls W for carrying and driving the bobbin fit loosely over the spindles S and may comprise the usual tubular bobbin carrying member T that is integral with a pulley P. A lower supporting flange 8 and an upper guiding flange g are integral with the pulley P, as shown. A supporting and lubricating washer w fits loosely over the spindle S and rests upon the rail R for supporting the said whorl while its interior is usually provided with lubricant retaining means for properly lubricating the running surfaces of the spindle whorl, etc. A driving belt or band B is in driving contact with adjacent whorls as shown in Fig. 1 and driven from a drum or other suitable source of power of the frame.
To prevent the whorls from a relative separating movement with respect to the lifter rail, I provide a hold down device 1 that preferably comprises a horizontal plate 2 having a downwardly extending flange 3 that is adapted to lie against a side edge of the rail R and which functions to locate the device with respect to the whorls lV. A screw 4 in threaded engagement with the plate fits loosely within an opening 5 of the flange 3 and secures the device in its correct relative position with respect to the whorls W. An upstanding web 7 integral with the plate 2 has oppositely extending horns or prong portions 8, the inner faces of which are preferably formed to a shape corre-' sponding to the contour of the pulley P, but, as will be seen in Fig. 1, are preferably not in contact therewith. The lower side of said prongs 8 are preferably spaced away from the upper face of the whorl flange s as best shown in Fig. 2.
In lieu of the means shown for securing the hold down device to the rail, it may be desirable to extend the flange 3 thereof to underlie the underside of the plate and toprovide a set screw therein that may engage the under face of the rail to hold the same in a rigid relation.
The hold down device is shown as being applied to the right hand side of the rail but it may be constructed to be applied to the left side or located at a point between the whorls and at the center of the rail.
The hold down device thus described has a portion that overlies a portion of the whorl and while normally it is not in contact therewith, yet the device is so constructed and arranged as to be engaged by the whorl and prevent or arrest any tendency of the same to move upwardly and away from the plate and its lubricating washer.
Having described my invention, it is obvious that many changes may be made in its construction or arrangement without departing from the scope of the invention.
l/Vhat I claim is:
1. The combination with a spinning frame having a lifter plate and whorls rotatable thereon, of a whorl holding down device comprising, a supporting base plate having angularly disposed sides for engaging adj acent sides of said plate, a portion extending from said plate that overlies a portion of adjacent whorls.
2. The combination with a spinning frame having a lifter plate and rotatable whorls thereabove of a whorl holding down device comprising, a base plate having angularly disposed sides adapted to overlie adjacent sides of the said rail, a web extending upwardly from said base plate intermediate adjacent whorls and portions extending from said web that extend in opposite directions therefrom to overlie a flange of said adjacent whorls.
3. The combination with a spinning frame including a lifter plate having adjacent hori- Zontal and vertical sides and rotatable whorls thereabove, of a whorl holding down device comprising, a base plate having adjacent horizontal and vertical sides adapted to overlie adjacent sides of said plate intermediate adjacent whorls, a web extending upwardly from the horizontal side of said plate disposed intermediate said adjacent whorls and portions extending from opposite sides of said web that overlie said adjacent whorls.
In testimony whereof I have ZL'lfiXGCl my signature.
EUGENE R. ALDERMAN.
