BRAIDING CARRIER.

Application filed February 26, 1927. Serial No. 171,121.

vention consisting in the improved tensioning means hereinafter fully described in connection with the accompanying drawings and being clearly defined in the subjoined claims.

Fig. 1 is a sectional elevation of a braiding carrier embodying my invention in preferred form.

Fig. 2 is a cross-sectioned view on the line 2-2 of Fig. 1. i 7

Figs. 3 and 4 are separate views of the tensioning spring and its connected springcarrier slide.

The carrier indicated comprises a base portion adapted to traverse the race-way,

2 and having a rigid tubular bobbin standard 11 rising therefrom upon which is mounted the bobbin 12; the extension of a spring 15 located within the tubular standard, by determined tensioning of the passing thread,

serving to operate a bobbin-releasing pawl or device 16. This general construction is old as shown in Staub Patent No. 1,360,810 of Nov. 30, 1920, and my invention consists in the specific improvements hereinafter fully described.

My main object is to provide for advantageously guiding the extensible spring located in the hollow standard, to insure its free movement therein without interference due to possible accumulation of lint from the thread or air compression, and to enable convenient positioning in the hollow stand ard of the released thread-guide eye with which the passing thread is engaged to carry the spring.

46 of this slide bar being bifurcated, to receive the body of the spring with the upper end thereof secured at 15; and the top portion being formed with a guide-eye 20* through which the bobbin thread 21 passes to the exit no eye 22 on the standard. When this combined spring and slide plate is placed in the standard, the lower end 15 of the spring is fixed to the latter by a cross pin 15 and the downwardly extending bifurcated portion '20? of the slide naturally seats upon the carrier base 10 when the spring 15 is released from tension, so that the top guide-eye 20?" will be positioned for engagement therewith of the thread 21. VVhe-n thus engaged, as in normal operation, the pull upon the thread extends the spring until contact of the carrier guide-eye 20 with the pawl 16 releases the bobbin to furnish an additional supply as usual.

The standard 11, as shown, is preferably formed of sheet metal, bent up to a tubular form having a square cross-section; the fiatbar carrier slide 20 for the springbeing arranged diagonally therein so as to be loosely guided in its spring-extending movement without turning action, thereby insuring its uniform positioning and uniform contact with the pawl, while the fiat form of the slide provides ample room in the tubular standard for its freefand rapid movement practically without possible obstruction at any point by accumulation of lint or otherwise; and the positive positioning of its guide-eye 20 when the thread isbroken or removed by the seating of the bifurcated lower end of the slide upon the carrier base 10, greatly facilitates reengagement of the thread therewith.

Automatic stopping of the machine in case of accidental thread breakage and dropping of the carrier slide 20, may be effected in well known manner, not indicated. The preferred construction specifically set forth may be readily modified within the invention as defined in the claims.

What I claim is:

1. In a braiding carrier comprising a base having a tubular bobbin standard with a thread guide projection, and a fixedly mounted bobbin-engaging pawl; a thread tensioning device in said standard comprising a slide plate formed with a guide-eye top portion adapted to operate said pawl and a bifurcated lower portion; and a slide connected tensioning spring adapted to normally seat said slide upon said base.

2. In a braiding carrier comprising a base having a tubular bobbin standard with a ositively thread guide projection and a fixedly mounted bobbin-engaging pawl; a thread tensioning device in said standard comprising a slide plate formed with a guide-eye top por- I tion adapted to operate said pawl and a bifurcated lower portion, and a slide-connected tensioning spring adapted to normally seat said slide upon said base; said tubular standard having a substantially rectangular crosssect-ion, and said slide plate being guided diagonally thereof with its bifurcated lower portion spanning said spring.

In testimony whereof I aflix my signature.

MAX KRISSIEP.
