HENRY JANSSEN, 0F WYOMISSING, PENNSYLVANIA, ASSIGNOR T0 TEXTILE MACHINE WORKS, 013 WYOMISSING, PENNSYLVANIA, 11 CORPORATION OF PENNSYLVANIA.

. Jeannine-MACHINE.

To all whom it may concern:

Be it known that 1, Henry JANSSEN, a citizen of the United States, residing at Vvyomissing, in the county of. Berks and State of Pennsylvania, have invented certain new and useful Improvements in Braiding-lVIachines, of which the following is a specification.

My invention relates particularly to what are termed lace-braiding machines, in whlch the carrier-drive mechanism provides for engaging or disengaging the carrier-drive member of different race-circles as determined by a jacquard or pattern controlling mechanism.

Each of such carrier-drive members commonly has a clutch engagement with the corresponding drive gear, and a vertically guided clutch-operating bar there-for to which periodic movement is imparted as re quired to give desired intermittent move ment to the engaged carriers.

The main object of my invention is to provide convenient and economical actuating connections between the circularly arranged series of clutch-operating bars and the pattern mechanism; and to this end it consists in providing each of the former with a self-carried clutch lever pivoted to one side of the bar and having an oppositely extending fulcruming arm normally held in contact with the machine frame by the clutch-releasing spring; such lever being capable of ready rotary adjustment upon the rod so as to bring its pivotal swing into the plane of its operating connection to the pattern mechanism; and no connection of the lever to the machine frame being required. The invention is fully described in connection with the accompanying drawing and is specifically pointed out in the claims. Figure 1 is a vertical section of a single clutch-operated carrier drive mechanism.

Fig. 2 is a cross-sectional view on the line 2-2 of Fig. 1, showing the adjustably connected lever-pivoting arm.

Figs. 3 and 4: are opposite edge-wise views of the lever connection.

Fig. 5 is a diagrammatic view indicating a plurality of race-circle posts with adjacent clutch operating rods and pattern control connection to the latter.

Fig. 1 shows a single race-circle post 10 having mounted thereon a constantly rotated drive gear 11 and a carrier drive mem- Specifieatioii of Letters Patent. Patented D 23 1919. Applicationfiled"Obtober 3, 1919. Serial No.328;176.

ber 12 movable into or out of clutch engage ment with said drive gear 11; with a clutchbar 13 vertically guided in the machine frame and having the end portion thereof which depends below the bottom plate 1 1 of the machine provided with an operating connection 15 to a pattern control mecha nism; a spring 16 being arranged to normally raise the carrier-drive member 12 out of operative engagement with its drive gear 11. This general construction is known, and the stop washer 30 which serves to hold the disengaged member is shown in Rahm Patent No. 1,282,945 of October 29, 1918. The connections 15 to the several clutch bars 13 of different race-circles, exten'd in diiferent lines to the pattern mechanism as indicated in Fig. 5.

In my improved construction each of these connections 15 is secured to a clutch lever 16 which is carried by its clutch bar 13 independently of the machine frame. A pivot arm 17 of said lever is connected to the laterally extending arm 18 of a separately formed bar attachment 19, the hub of which latter is rigidly secured to the depending end of the bar by means of a setscrew 20; and a fulcruming arm 21 of said lever extends to the diametrally opposite side of the rod and has an end portion 22 arranged to bear against the bottom plate 14 of the machine. So that when thus connected to the clutch bar 13 said fulcruming end 22 of the lever will be normally pressed against said bottom plate 1 1 by the action of the spring 16, and when such pressure is increased by a pull upon the depending arm 23 of the lever exerted through its pattern connection 15, it will serve to pull down the clutch bar (as indicated by the dotted lines) and so engage the

clutch members

11 and 12. The slight swing of the lever required to effect such engagement, and the length of the slender connection 15, permit of the latter being loosely and adjustably connected to the lever arm 23 without jointing, as

shown.

and satisfactorily operative Without providing any frame connection for the lever.

What I claim is:

- 1. In a braiding machine comprising a bottom plate provided with a series of racecircle posts each having mounted thereon a driving gear and a clutch-engaged carrierdrive member; a series of clutch-operating bars vertically guided in said bottom plate,

each of said bars being provided with a spring adapted to normally raise the same, a lateral extension at its depending end, and

a lowering lever therefor pivoted to said lateral bar extension and having a fulcruming arm pressed against said bottom plate at the opposite side of said rod.

2. In a braiding machine comprising a bottom plate provided with a series of racecircle posts each having mounted thereon a driving gear and a clutch-engaged carrierdrive member; a series of clutch-operating bars vertically guided in said bottom plate, each of said bars being provided with a spring adapted to normally raise the same, a laterally extending ivot arm adjustably secured to its depending end, and a lowering lever pivoted to said arm and having a fulcruming arm pressed against said bottom plate at the opposite side of said bar.

In testimony whereof I aflix my signature.

HENRY J ANSSEN.
