Tb aZZwiom it mag/concern." f I t.
Be it 'known that we, CHARLE?? STONE and IVILLIAM SPENCER, citizens ofthe United States,y residing atk Lewiston, in'ithe county of Androscoggin" 'and' State." of
Maine, have invented certain new and' useful Improvements in Shuttles; and lwe do declare the following to be a full, clearand exact description ofthe invention, such as will enable others skilledin the art to Which it appertains to make and use thesame;V
vOur inventionvrelates to improvements ,inA
shuttles and' more particularly those now employed inthe weaving of rayon orarti-.
ficial silk.I
At the present time,quantity weaving of this artificial. silk on automatic looms is impossible because the filling shells off, that is, it'formsY wads and becomes'matted and does not feed evenly from ,thev bobbin. In attempting to overcome this objection, flannel, sheepl skin and different kinds ofy fur havebeen placed upon the sides and bottom` and while being effective to a'limited degree, the arrangement prevents dofling out an Iempty bobbin and replacing it with a full one on an automatic machine. Therefore,
with the resultv that imperfect cloth isproduced, and even though imperfect, quantity v Y f the bristles 7 are arranged 1n different planes being supplemented by the accompanying` drawing.
Figure l is a plan view of a shuttle provided with our improved tensioning device;
Figure 2 is a side elevation thereof; Figure 3 is a sectional view taken substantially on the line 8-3 of Fig. 2; and
Figure 4 is a sectional view/,taken substantially onthe line 4-4 of Fig. 3. In the accompanying drawing, we have illustrated a conventional form of shuttle comprising a body 1 having the usual bob- 'bin-receiving;chamber 2 at oneend of which vis mounted `va spring' bracket 3Y for'fs'npporting thebobbin or spindlefupon vwhich the fiiling is wound. This bobbin ma-y.,l be Areadily removed from the chamber y2 and when in theposition shown' inFig. 1,the*
@filling o r' thread carried thereby may be unwoundand threaded through the'usual eyelets' or 'way's' to the weavinggmachinery. -""While other means maygv'bfe employed for vmounting the-set of tensioning deviceszwith- "inthe bobbin chamber 2,1 we preferably em- 'ploy 'l the "structurel shown. This preferred type consists 4iin providingvthe `opposed walls f of the "shuttle Withfsockets or recesses 6 arranged foblique to the longitudinal center v'of the shuttle` for mounting tufts or Vbristles --7 whose outer end portions 8 :bear .lightly "upon the-filling or thread carriedvv by fthe bobbin '4. Due to the oblique arrangement of the openings inwhich the, base portions of the bristles are fixed, the outer end portions of thetufts 7 will be inclined Substantially in 'the direction in which the thread travels while being unwound in consequence of which the resistance to the unwinding of the thread will be negligible,
yet the pressure will positively prevent shelling or wadding. Y
By reference to Fig. 4, it will be `noted that so that they engage, opposite faces of the bobbin or filling carried thereon. In actual practice,`wev have found that the greater I tensionshould be exerted lupon the lower face vofthe filling, in consequence of which we provide two longitudinal rows of these tufts of. bristles which are preferablyrf'although not necessarily arranged in staggered or zig-Zad relation.
We have condiicted extensive'experiments in different arrangements of these tufts of,k
of the filling or thread is absolutely eliminated and hence the emptied bobbins may be readily replaced with full ones as is usual inthe automatic looms. We are aware of certain prior patents which embody elements designed to exert tension upon a filling carried by a bobbin but find that none of these devices will operate to effectively prevent v'shelling or wadding of this new fibre rayon or artificial silk.
Excellent results have been obtained from the details disclosed and they are therefore preferably followed, but within the scope of the invention as claimed, other structures may well be used to advantage. It is obvious that these tufts of bristles may be mounted within thc bobbin ch amber in many other ways.
We claim:
l. A shuttle including a bobbin chamber having opposed side walls5 a filling receiving bobbin in said chamber, a single row of longitudinally spaced tufts of bristles extending obliquely into the chamber' in the direction of discharge of filling, said tufts being arranged near the upper edge of one wall `to yieldably contact with filling, and a pair of parallel rows of longitudinally spaced tufts of bristles extending in the same direction as the first named tufts and arranged adjacent the lower edge of the other side wall for yieldable pressure upon a portion of the filling to one side of a ver- Vthe first named means to yieldably exert additional and greater Ipressure upon a portion of the filling circumferentially spaced from the portion thereof engaged by the first named means.
3. A structure as specified in claim 2; said means comprising longitudinal rows of bristles projecting inwardly from the shuttle bobbin.
. 4. A structure as specified in claim 2; said means comprising rows of longitudinally spaced tufts of bristles extending obliquely into the chamber in the direction of discharge of filling, said rows extending substantially the entire length of the bobbin.
In testimony whereof we have hereunto affixed our signatures.
CHARLES M. STONE. WILLIAM H. SPENCER.
