BRAIDING-MACI-IINE.

Specification of Letters Patent.

Patented Sept. 7, 1909.

Application filed. May 11, 1906. Serial No. 316,236.

To all whom it may concern: I

Be it known that I, R BERT C. RAHM, a citizen of the United States, and a resident of yomissing, in the county of Berks, State of Pennsylvania, have invented certain new and useful Improvements in Braiding-Machines, of which the following is a specification.

My invention relates to braiding machines adapted to produce figure effects, and my object is to provide sectional carrier courses embracing predetermined portions only of the main course and upon which certain of the carriers are traversed in cooperation with those upon the main course.

The invention is fully described in con-.

provements are shown applied to such a machine, the double-course being made up of communicating inner and outer series of race circles, a and b respectively, with switches 0 between them governing the movement of the carriers from one series to the other as fully described in said prior application.

My present improvements consist in providing for the reversal of desired carriers at different pointsin the main course, and for traversing such reversed carriers for desired periods in sectional courses embracing determined portions only of the main course, and in cooperation with other carriers traversing the main course. This main course is shown arranged to produce a plain alternating pairs f and g g, as in Fig. 1. In connection with each of these side track race-circles f and g, a switch it is provided to control the direction given to successive carriers, either to continue the latter in the main course or to divert them into the connecting side-track circle for reversal into the sectional course of which said side-track circle forms a part. In a complete machine providing for a maximum number of sectional courses, the total number of side-track race-circles (f and 9) will be equal to the number of directly connecting race-circles in the main course.

The operation of the controlling switches to govern the course traversed by the different carriers is automatically efi'ected by suitable jacquard mechanism. Several of the numerous sectional courses possible are indicated in the drawing by heavy serpentine lines which include the side track racecircles employed therefor. Thedouble main "the side-track race-circles may obviously be employed in connection with the ordinary single maincourse, as in Fig. 2. The variety of sectional courses attainable may be further increased by duplicating the side-track racecircles and switches, upon the inside as well as the outside of the main course as indicated in Fig. 2.

In applying the invention to a socalled hercules Vmachine, in which six-horn drivegears are employed in the main course, the side-track race-circles. (f and g) are adapted for five-horn and seven-horn drive gears respectively, instead of three-horn and the homes previously described; and in either type of machine the main course may be arranged for forming tubular braid with a capacity for changing to flat by using any elected side-track circles as terminals, thus permitting the flat braid to be made of any width provided within the full circle. Or multiple braids of disconnected narrow widths can be simultaneously produced by using different of the side-track circles as terminals for each of such narrow braids or strips; all of the carriers being in such case traversed in the sectional courses so formed instead of retaining some of them on the main course to unite the sections as previously described. These and other variations of the specific construction shown may obviously be made without departing from my invention.

lVhat I claim is 1. A braiding machine having two parallel communicating race-circle courses, and connected side-track race-circles each provided with a drive-gear having an odd number of carrier-en 'aging horns and with a controlling switc 1, whereby sectional carrier courses may be formed each employing two of said side-track race-circles as terminals, substantially as set forth.

2. A braiding'machine having two parallel communicating racecircle courses, conn'ected side-track race-circles arranged in pairs at diiferent points of the parallel courses and each provided with a drive-gear having an odd number of carrier-engaging horns, and a controlling switch, and carriers adapted to be traversed either in said parallel courses or in sectional courses having terminals formed by said side-track race-circles, substantially as set forth.

In testimony whereof, I aifix my signature, in the presence of two witnesses.
