To all whom it may concern: 7 7
Be it known that I, ANKER PETERSEN, a
citizen of the United States of America, and
resident of Winthrop, in the county of Suf- Massachusetts, have infolk and State of vented new and useful Improvements in Braiding Dies, of which the following is a specification.
The present invention concerns braiding machines of that type employed in the manufacture of braided cord or thread and relates more particularly to means for ensuring uniformity of tension .inthe strands;
of the finished braid.
I The principal object ofthe present invention is to provide an improved form of braiding die or condenser, comprising means for retarding or holding back any slack portion or bight of a. strand or strands as they are intertwined at the braiding point,'thus to ensure substantially uniformtension in each strand of the finished braid as the latter is drawn off by the take-up device,but so constructed and arranged as to permit the passage of knots or slubs, without putting undue strain upon the strands, and to pro vide means whereby the die or condenser may be heated if desired for imparting a set to the strands comprisingthe braid and for giving a finished appearance to the latter.
In the accompanying drawings a '.pre-
invention is illus trated and in such drawings a Fig. 1 is a fragmentary side elevation of a braiding machine such as is shown in the patent. to Petersen, No. 1,413,773 dated April 25, 1922, device of the present invention being shown as 7 applied thereto;
Fig. 2 is a fragmentary horizontal cross section on the line 2-42 of Fig. 1' and indicating the position of the braiding die forming the subject-matter of the present application;
Fig. 3 is a vertical diametral cross section' to large scale showing theimproved braidin die ig. 4 is a transverse cross section on ,thel
line l4ofFig.3;
Fig. 5 is'a perspective view of the braid compressing blade constituting an essential.
feature of the improved die;
. Fig. 6 is a employed for F ig 5;
; braiding frame 7 is wheel 9 which of well known type and leaf spring of bow form is perspective view ofv 'a' spring actuating theblade shown in sectionthrough the braiding die tolarger scale showing the formof the inner edge of the blade; and r 7 Fig. 8 is a fragmentary diametraljcross section illustrating the lower part of the die onan enlarged scale and indicatingthe position ofthe braiding point and of the braid as it passes through the die.
Referring to the drawings the numeral 1 indicates the circular frame of the machine supported upon legs 2 and having the circular disk-like support 3 constituting a track along which the braiding carriers 4: (Fig.
2) of the inner series may travel." The numeral 5 indicates the support for'the outer series of braiding carriers 6. I An upper provided which bridges the ma- Fig.7 is a fragmentary, transverse cross i chine and hasa bracketS inwhich the upper end of the braiding die may beclamped, This upper frame also supports 'the take-up may bedriven in any suitable manner and which may be provided with a countingmechanism 10 if desired. v
Referring more 8, the improved die is shown as comprising a substantially cylindrical elongate member l1v having an. axial-bore or ,passage; 12 through which the braid may travel, A radial slot l3'extends outwardly from one, side of this passage to the exterior of the member 11. This slot is somewhat narrower at its inner portion and has a movable'blade 14 fitting within such narrow portion; This blade is of substantiallythe. same length asthe member 11 and is grooved "at itsinner edge to provide an arcuate surface'15 constituting aportion o'fthef side wall-of the passage 12. The upper end ofthe blade 14 is preferably made som ewhat widerthan the, l A
r mainder as indicated at;16 (FigSfl n of the "blade'is' chamwhile the lowerend fered on at 17 to facilitate the movement oftlie blade as will hereinafterfbe described, Preferably also the lower end of ,the, channel;

*lower end or braiding point;
tively, bearingagainst the inner walls of a pair of caps 24, 25 fitting snugly over the and lower ends respectively of the to retain the spring 20 within the slot'and indirectly to prevent escape of the blade l l' from the slot. The cap 24: is provided at its end with an opening 26 for the passage of the braid, this opening aligning with the passage 12 in 11. The lowercap is "provided with a beveled end surface 27 and has an opening 28 in its end aligning with the passage 12 in strands fail to bear their due proportion of which the finished braid may By the, employment of' the present device each strand as it arrives at the braiding point is retarded in its movement by reason of 14: against the braid, this pressure serving to hold back any strand which may be slack, so that as the several strands emerge from the braiding die in the'finished braid they all have substantially the same tension. If the strands were alwaysperfectly smooth p and free from knots or slubs, it might be possible to secure the desired result by passingthe braid as it any strain to leaves the brading point through a re stricted channel or passage having immovable side walls but as knots or slubs are he 'quently incorporated in the stands such an arrangement would quickly result inthe the braid or of individual the movable blade has been provided with the spring for resiliently It is desirable however, that su'ch blade besubjected to considerable pressure in order to secure the desired' results and to permit of such ressure while at the same time to allow the blade to' move outwardly under the impact of a ;knot or slub, it is preferred to causethe spring to bear upon the blade at a single pointso thatfthe blade is free to rock aboutthispoint as a fulcrum as the knot or slub traversesthe' passage 12 and it "is further preferred to arrange the fill- 'crum point nearer to that end, of the .die
from which the bra-ll emerges-than to the VJith such .22, 23 respec- 11. The beveled the pressure of the blade the die at an arrangement the entering slub or knot acts wltha long leverage'to swing the blade outwardly, thus avoiding any sudden strain. upon the individual strandand permitting the knot or slub gradually to be compressed as, the braid traverses the passage 12 so that by the time 'it reaches the fulcrum. point there is little -danger of subjecting the strand to sufficlent strain to cause its breakage;
In Fig. 1 a heating coil 30 is shown as surrounding the cylindrical member '11, this heating coil comprising a plurality of turns of insulated electric wire mounted between the heads 31 and 32. These heads are preferably positioned by engagement with the. inner ends of the caps 24, 25 respectively. Lead wires extend from the coil and may be connected with suitable source of electrical energy. the use of a heating coil at this point the strands forming the braid may be given a permanent setso that they tend to retain their relative positions in the braid, thus manner is of particular advantage when one or more .of the strands forming the braid are caused topass through a sizing bath or other conditioning medium prior to incorporation in the braid, as in this case the heated die may be caused'to produce a glossy finish upon the braid adding very materially to its appearance and its desirability as a sewing thread. hile an electric heating coil is herein disclosed it is evident that a steam coil or 'in fact any other desired heating means might be employed for the purpose.
