To all whom it may concern:

Be it known that I, ADoLPH MANN, a citizen of the German Empire, residing at Barmen, in the Province of Rhenish Prussia. and Kingdom of Prussia, have invented certain new and useful Improvements in Braiding- Machines, of which the following is a specification.

This invention relates to improvements in braiding-machines of that class where the bobbins are enabled to run from disk to disk, as usual, and where they may also be kept on one disk only, on which they are carried round for a longer or shorter period, according to the design of the lace or product to be made. In the machines used hitherto for attaining similar results the regulation of the course 0 the bobbins is by the use of switches and like devices. In the present invention, however, said regulation is by means of a special and peculiar construction of the rivers, which also causes the advance of the bobbins. The curved slotted paths in the u per machine-plate are of usual shape, so t rat a bobbin may be directed to the right or left at any crossing-point of the two slotted paths-that is to say, so that it ma T be shifted farther on or kept on the same plate. The drivers are constructed in the form of hooks. They are set at right angles to each other that is to say, they change their position alternately. When the hooks of the one stand radially, those of the adjacent ones stand in the direction of the tangent to the respective central radius of the driver. The bobbin brou ht to the crossin place of the curve can then e taken up by t e adjacent driver and carried on to the next plate, when the hook parts of the drivers have been brought in their respective positions. By these posi tions of the hooks the longer or shorter stay of a bobbin on a plate is decided. It remains on the same plate as long as the hook is held up, when of course the adjacent one is held down, and it is carried over to the next plate as soon as the hook on the driver carrying the bobbin is dropped and that on the adjacent driver or plate is raised. If neither of the hooks of the adjacent plates or drivers are raised, the bobbin remains still on the crossing-point between two plates.

In order to be able to regulate the workin of the drivers and their hooks, as describer the regulating device, a peculiar jacquard mechanism, is so driven that its main s indle makes one complete revolution whi e the bobbin-drivers make threefourths of a revolution only. For the sake of securing a safe working of the machine and preventing the running against each other of two bobbins when their respective driver-hooks are raised and lowered, respectively, the bobbin-carriers may be provided with two downwardlyprojecting studs or feet each, and the size of the driver-heads in this case may be made so that they do not reach into the paths of each other. i

In the accompanying drawings I have shown so much of the improved machine as will be necessary for the understanding of the same and its working.

Figure 1 is a vertical section along line I I of Fig. 2. Fig. 2 is a view in lan of Fig. 1, partly in section along line I II of Fig. 1. Fig. 3 shows in a vertical section on line 111 III of Fig. 4 the construction of the gears and the device for raising and lowerin the hook-drivers of the same. Fig. 4 is a hork zontal section along line' IV 1V of F ig. 3. Fig. 5 shows part of the said machine in plan.

The same and similar parts are marked by the same numbers of reference.

By 1 is indicated the upper machine-plate.

2 is the lower plate, on which are fixed the pillars 3, carrying the disks 4, in proximity to the machine-plate 1. The inner and outer sections of this plate and the edges of the disks 4 form the curved path 5 of the bobbins. As stated above, this curve is so shaped that a bobbin located at a crossing-point may be carried round by the disk supporting it 91' it may be guided over to the next adjacent disk. On the pillars 3 are held movably the spunwheels 6, which are in gear with the similar wheels of the adjacent pillars right and left. They all have long bosses on which the drivers 7 are splined, so that they may be shifted u and down thereon, though turning only witi said wheels. The up-and-down movement of the drivers is caused by a ring or collar 8, placed in a circular roove of the hub of the driver, so that it can be raised and lowered by a forked bell-crank lever 10, having its fulcrum on a bolt 9, held in a bracket 9, fixed to the lower machine-plate 2. In order to cause this axial movement of the driver, the vertical arm of said lever is connected by a rod 11 to the bell-crank lever 12 of a jacquard mechanism herein described, the said rod being pivotally at tached at one end to the said arm and bent at the other end to enter the slot 12 in the lower end of the said bell-crank lever, thereby preventing binding. A spring 17, fixed by one end to the bracket 9 and pressing by its other end against the vertical arm of lever 10, has the tendency of keeping the driver 7 in its lowered position on the hub of the wheel 6. The said jacquard mechanism is on the whole of usual construction, and only those parts are described which had to be altered to answer the requirements of the present invention. The lifting wires 13 are indirectly connected at their lower ends by adjustable links 27 to the lovers 12. in their lower position they rest on the fixed bar 14, and they can be raised by the lifting blade 15, in which position they can be kept by the fixed blade 16, a transverse lifting wire 16 being attached to each wire 13 and arranged and adapted to rest on said part 16 when wire 13 is thus lifted, thereby preventing the descent of the latter. When the lifting wire 16 is pushed off the blade 16, the spring 17 and the weight of the driver will cause the latter to fall down into its lower position on the hub of the wheel 6. The inner end of each lifting blade 15 is mounted on a short rock-shaft 30 on a fixed part of the machine-frame and also pivotally connected near its middle to a block or arm 29, adjustable on an operating-arm 29, driven by an eccentric 28 on shaft 25. The action of said shaft, eccentric, and arm is to lift and lower the blade 15 at regular intervals. Simultaneously the jacquard-cylinder 24 is turned step by step by the intermittent pull of a long pawl or feeding-arm 31, the hooked end of which engages a ratchet-wheel 32, turning with said cylinder. This arm or awl is detachably fastened to the outer en of an arm 33 of rock-shaft 30. The drivers 7 have two hooked wings 7, (shown in Figs. 3 and 4,) and by these hooks they will engage the downwardly-projecting

studs

26 or 26 of the bobbin-carrier when they are raised as indicated in dotted lines in Fig. 3. Thus the bobbin will be carried by the respective driver-hook onto its disk, and it will be carried round by the same as long as the driver is held in the raised position. The hooks of two adjacent drivers are placed at right angles to each other, as will be best seen from Figs. 4 and 5. This is necessary because the jacquard mechanism cannot simultaneously push off and lift one wire 13 to lower the driver and place another wire 13 in position for raising the next driver. By arrangin the hooks of two drivers as above state sufficient interval will be provided for raising the second driver until the bobbin has come within its reach and may therefore be seized and carried safely around by said driver.

Gear-wheels 18 19 20 21 22, Fig. 2, oonstitute a connecting series from one of the gear-wheels 6 aforesaid to a gear-wheel 23, turning shaft 25, and are calculated to turn the latter shaft through an entire rotation while the wheels 6 and the wheels 7 of the braiding-machine are making three-fourths of a rotation.

The carriers 26, as will be seen from Figs. 1, 3, 4, and 5, are provided with two downwardly-projecting

studs

26 and 26 arranged right and left with respect to the center 26 of the bobbin-carrier, which is guided in the curved race, so that one of them will be within reach of the driver on the left of the bobbin and the other one within reach of the driver on the right of the bobbin when said drivers are raised, and since always only one of the drivers can be raised the running together of two bobbins or the directing of one into the race curve of the other one is avoided, and very uick working of the machine is made possib e. Besides this the new devices in question give almost absolute surety that the bobbins will be carried over from one disk to the other, and this especially so when the studs of-the bobbin-carrier are placed somewhat out of the middle and a little toward the front side of the foot-plate of the carrier.

hen in the new machine the adjacent drivers are raised and lowered alternately in regular succession, the bobbins make their course as is the case in an ordinary braiding machine, with the only difference that the bobbins always stop for an instant at the crossing. This stoppage is, however, so minute that it will not be observed when the machine is worked at the ordinary speed. As long as a driver is raised its correspondin bobbin will be carried round on the same disl until the driver is lowered, and when a driver is lowered without raising the one of the adjacent disk then the bobbin remains stationary at the crossing-point between two disks.
