BRAIDING CARRIER.

Application filed April 10, 1926. Serial N0. 101,021.

My invention relates to braiding machine carriers having brake tensioning mechanism; and it consists in an improved construction comprising an axially movable bobbin-supporting pin in connection with a movable pin-retaining device the pin-releasing movement of which is adapted to simultaneously release the tensioning brake,

as fully set forth in connection with thev accompanying drawings and defined in the subjoined claims.

Fig. 1 is a face view of a carrier embodying my invention in preferred form; the pin-retaining device being shown in pinreleasing and brake-releasing position.

Fig. 2 is a cross-sectional view on the line 2 2 of Fig. l, the bobbin being removed.

The carrier shown is provided with a vertical bobbin-supporting standard 10, in which the bobbin wheel 11 is mounted between parallel standard members upon a horizontal supporting pin 12; the tensioning of the leaving` thread which passes through the fixed guide eye 13 of the standard, being controlled by a brake mechanism comprising a lever 14 pivoted to the standard at 15 and itself pivotally carrying a brake shoe 16 which is normally spring-pressed against the rim of the bobbin.

To provide for easily mounting or removing the bobbin 11, the pin 12 is so arranged as to be axially movable in the standard though normally held in proper bobbin-supporting position; a movable pin-retaining device 20 being adapted to automatically release the bobbin from the thread-tensioning brake when said device is moved so as to release the pin for freeing of the bobbin therefrom. As shown, the bobbin-pin l2 is insertable through an aperture 21 in the near member of the bifurcated standard 10, and after passing through the bobbin 11 is engaged in the spaced-apart standard member; so as to be supported by the standard at both of its ends but capable of being withdrawn by a reverse movement unless it is locked in bobbin-supporting position by said pin-retaining device 20. Thelatter is shown as swingable upon a pivotal connection 22 to the standard, so as to cover the inserted end of the bobbin pin 12 when the device is lowered to its fixed rest 23 on the standard; or to uncover it for ready withdrawal when t-he device is in raised position as illustrated.

The pivoted brake lever 14 is provided withan upward extension 14LL which is arranged to overhang the lowered pin-retaining device. 2O when the brake shoe 16 is in tensioning contact with the bobbin 11; so that when said device is raised to its pinreleasing .posit-ion against stop 25 on the standard, it engages said overhanging lever extension to swing the brake lever 14 into releasing position, and so retain it, as illustrated. l/Vhen the device 20 is thus raised both the bobbin and its supporting pin are released to permit of free engaging or disengaging axial movement of the pin; but when it is lowered the bobbin is automatically subjected to the tensioning action of the brake, and the` pin is at the same time positively retained in its bobbin-supporting position.

As shown the axially movable pin has one end non-rotatably inserted a proper distance into one o-f the standard members so as to be readily withdrawn when the retaining device is raised, but obviously this and other preferred construction specifically set forth may be modified within the invention as defined in the claims.

What I claim is 1. A braiding carrier comprising a bobbin-carrying standard, a bobbin pin horizontally mounted in said standard so as to be disengaged therefrom by axial movement in one direction only, a brake lever pivoted to said standard, and a pin-retaining device movable into position -to simultaneously release the bobbin pin and the brake.

2. A braiding carrier comprising a bifurcated standard, a transverse bobbin-carrying pin removably insertable through an aperture in one of the spread standard members into engagement with the other member, a brake lever pivoted to said standard, and a pin-retaining devicevpivotally movable into position f or simultaneously uncovering said aperture and engaging said lever to release the braking aotion thereof.

3. A braiding carrier comprising a bifuroated standard, a transverse bobbinoarrying pin removably insertable through an aperture in one of the spread standard members into engagement With the other member, a. brake lever pivoted to said stand-l ard, and having a portion thereof extending above said pin aperture, and a pivotally mounted pin-retaining device swingable into brake-retreating engagement with said lever extension. i

In testimony whereof `I aiix my signature.

HENRY JANSSEN.
