BRAlDlNG-VIACHINE.

SPECIFICATION forming part of Letters Patent No. 468,997, dated February 16, 1892.

Application filed October 7, 1891. Serial No. 408,007. (No model.)

To @ZZ whom, #may concern:

Be it known that I, WILHELM MUNDT, a citizen of the United States, and a resident of New York city, in the county of N ewYork, in the State of New York, have invented certain new and useful Improvements in Braidin g-Maohines, of which the following is a specication. n

This invention relates to improvements in that class of machines that are used for making braids, and are constructed with a series of notched wheels mounted on the same shafts with engaging cog-wheels or any other driv-l ing-gear, said notched wheels serving` to carry spool-holders in serpentine curves around ixed spool-holders for the purpose of producing the proper unlocking and binding of the threads forming the braid. Said notched wheels are usually made for a certain kind of braid, and only this certain kind of braid can be made on the machine.

The object of my invention is to provide a braiding-machine on which different kinds of braids can be made without requiring all the wheels of the entire train to be changed, all that is necessary being to make a change in the end wheels of the train.

My invention consists in a usual braidingmachine having notched wheels provided with additional notches, the end notched wheels being readily removable, so that they can be replaced by Wheels lwith dierent notches, ac-

cording to the kind of braid to be made.

The invention also consists in the construction and combination of parts and details,

which will be fully described hereinafter, and

' finally pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of the gearing of my improved braiding-machine, the top plate in which the guide-slots are formed being removed. Fig. 2 is a plan view of part of the base-plate, showing the slots for adjusting the end wheels. Fig. 3 is a plan view of` part of the gearing for making a certain kind of braid. Fig. Liis a plan view of part of the bottom plate of the machine, showing dierent end Wheels from the construction shown in Fig. l for the purpose of making different kinds of braid. Fig.

5 is a plan view of part of the gearing corresponding to Fig. 4. Fig. Gis also a plan view of part of the bottom plate of the machine, showing another arrangement of wheels for making still another kind of braid. Fig. 7 is a plan view of part of the gearing for the arrangement shown in Fig. 6. Fig. 8 is a plan view showing the adjustmentof the end wheels of the train of gearing. Fig. 9 is a plan view of the top plate, showing the detachable section for guiding the end wheels. Fig. lO is a plan view of said detachable section. Fig. 11 is an enlarged detail sectional view on the line 1l ll of Fig. l, showing the arrangement of the wheels.

Similar letters of reference indicate corresponding parts.

In the base-plate A the spindles B are fixed on a circular line in the manner as customary in braiding-machines, and on each spindle B a sleeve C is mounted. On the bottom of each sleeve C a cog-Wheel D is formed, and on top a notched wheel E. All the notched Wheels E, with the exception of the end wheels, are provided with eight notches, of which four are arranged quarter-circle from each other, and of these two diametrically-opposite notches a have an additional notch b at each side, so that four of the notches are separated a quadrant and six notches are separated from each other a distance corresponding to an arc of thirty degrees. I have shown nineteen notched wheels, where it is evident more or less may be used, as may be desired. The top plate F is provided with a series of adjacent openings F in the usual Way, below which openings the notched wheels E can rotate, and on the upper end of the fixed spindle B plates A3V(shown in dotted lines in Fig. 2) are held, which with the edges of the openings F guiding the movable spool-holder. The end Wheels E of the-train-gearing yare made integral with a sleeve C, at the bottom parts of which a cog-wheel D is formed, said sleeves C being mounted on the movable spindles H, which pass through the slots I- in the base plate and are locked in the desired position by means of the nuts J.

form the slots in the usual mannerfor wheel D must have forty-two.

As shown in Figs. l, 2, and 3, the machine v, is adjusted for .making so-called Hercules braid, and in this case the end wheels E have seven notches, forming seven wings between thenotches, and the gearing must be so arranged that the lower ends of the spool-holders pass into notches a in the wheels E, that areseparated from each other by segments corresponding to sixty degrees--thatis to say, the notches into which the spool-holders pass must be one-sixth of the circumference of the wheel from each other. For example, in Fig. 1, for the first wheel E the spool-holder would pass into the notches marked l, 2, 3, 5, 6, and 7 and the notches 4r and 8 would not be used, and every time that the wheel E makes a seventh of a revolution the first wheel E must make one-sixth of a revolution, so that the notches a a of the Wheels E and E will register to permit the lower end of the spoolholder to pass from the notch a inthe wheel E into a notch a or b of the iirst Wheel E. As the other wheels E are all geared alike, it will follow that the notches 1, 2, 3, 5, 6, and 7 of each Wheel E are used for this kind of braid.

In order to rotate the wheels E and E at the. proper speed, the proportion of the gearwheels D and D corresponding to the wheels E and E must be as six is to seven.l For example,.if the cog-wheel D has thirty-six teeththat is, six to each subdivision-then the cog- The cogwheels D remain permanently in the machine, but the cog-wheels D are replaced with lthe corresponding wheels E for the certain kind of braid to be made. According to the diameter of the wheels E D the spindles H must be shifted in the slots a greater or less distance from the first Wheel ED.

In the construction shown in Figs. 4t and 5 so-called binding-braid7 is to be made. In this arrangement the wheels E have five notches a, and only the four notches a of each wheel E are used, which notches are a quadrant from each other. The notches 2, 4, 6, and 8 only are thus used, and thenotches 3, 5, 1 and 7 are idle; or, in other words, the wheels E must take one-fifth of a revolution every time the wheels E make a quarter of a revolution, and for that purpose the proportion of the wheels E D to the wheels E D must be as 4 is to 5. As each wheel E D in the machine has thirty-six teeth, as previously mentioned, the wheels D now used must have forty-ve teeth, in contradistinction to the wheels D used in the arrangement shown in Figs. 1 to 3, which had only forty-two teeth. The spindles H must thus again be moved a greater distance from the fixed spindles of the end wheels ED.

Figs. 6, 7,- and Sshow the arrangement for making diamond braid. In this construction 4the second, fourth, sixth, and eighth notches a of each wheel E are used, and the wheel E must have six notches and must make one- `well-known manner.

sixth of a revolution. The'pro'portion of the wheels D to D and E to E must be as four is to six, and as the wheels D have thirty-six teeth it follows that the wheels D must each have fifty-four teeth. The wheels E are now of such a diameter that they are in contact with the end wheels E and also with each other, and the direction of movement of the spool-holders is not reversed at the end of the `train of gearing, as shown in Figs. 1 and 4,

but the spool-holders continue on, traveling in the same direction around the machine. Itis evident that for each change made in the size of the wheels E E and corresponding Wheels D D the spindles H must be shifted, and likewise that. part ofV the top platesF in which the wheels E E revolve must be adjusted accordingly. To permit of such an adjustment said top plate is provided with an opening M, in which the detachable plate N, provided with fastening-clips O,-

fits. .Every time the wheels E D E D are changed the detachable plate N must be removed to be replaced by another corresponding plate.

P P P P are cog-wheels engaging some of the wheels D and are driven by beveled gearing Q from the driving-shaft in the usual By thus merely interchanging or replacing the end wheels of the train of gearing the machine can be used for making different kinds `of braid without requiring any adjustment or change whatever of the remaining parts of the gearing and without requiring the detachment of lany parts of the frame. This change can be made in a very short time, and thus this machine can be used for the same purposes forv which formerly three distinct and separate machines were used.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A braiding-machine constructed with a row of engaging cog-Wheels, a corresponding row of notched wheels united with the cogwheels,said notched Wheels each having four notches separated a one-quarter circle from each other, and at two ot' said notches located diametrically opposite each other an additional notch arranged at each side of each of said two diametrically-opposite notches, substantially as set forth.
