BRAlDlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 399,623, dated March 12, 1889.

Application filed August 27, 1888. $erial No. 283,860- (No model.)

T0 whom it may concern.-

Be it known that I, \VILHELM MUNDT, of Brooklyn, in the-county of Kings and State of New York, have invented. certain new and useful Improvements in Braiding-llachines, of which the following is a specification.

This invention relates to improvements in that class of machines known as braidingmachines, and which are used for making braids, covering molds with braided fabric, for making tubular laces, and other similar purposes.

The object of my invention is to provide a machine of this kind in which there is as little lost motion as possible, and all the spools begin to turn and travel at precisely the same time with the same speed.

In the accompai'iying drawings, Figure l is a side View of my improved braiding-mac]line. Fig. 2 is a plan view of the gearing for retating and conveying the spindles. Fig. 3 is a detail enlarged vertical. longitudinal sectional view of the series of gear-wheels, sleeves, and spindle-moving wheel. Fig. i is a plan view of thesame, parts being broken out.

Similar letters of reference indicate corresponding parts.

The spools A, on which the threads for making the braids are wound, are each mounted on a spindle, B, provided with a iiat part, 0, which can travel in the crossed serpentine slots 1) in the top plates, E, of the machine, in the usual manner. Below the flattened part '7 each spindle is provided with a pivot or pin, F, which can enter notches E in the rims of a series of wheels, F, mounted on the upper ends of sleeves G, provided on their lower ends with cog-wheels ll, engaged with each. other, said sleeves G being mounted on pins .T, secured in the top plate, E, and bottom plate, K. The rims of the wheels F are rabbeted, so as to overlap or ii'iterlock, as shown in Figs. 3 and i, thus permitting parts of one wheel, F, to project over parts of the other, as is necessary for conveying the spindle 1-3 from one wheel to the other. ll eretofore the wheels also overlapped each other, one wheel being placed above the other. The pin or pivot F on the lower end of the spindle B was not held securely and was very apt to wabble,

thus preventing running the machine at high speed. In my improved machine the tops of the notched wheels are in the same plane, which possible, as the rims of the wheels are rabbeted, and thus said pins or pivot-s are held securely and cannot wabble, and are not subjected to any undue friction 01' pressurcs.

The several cog-wheels H are engaged with each other and arranged in a circle, as shown in Fig. 2. lleretofore only one of said circle of cog-wheels was engaged with the drivinggear, and motion was transmitted from one cog-wheel to the other around the entire circle. It is evident that with this construction there was more or less lost motion, and when the machine was started some spools rotated some time before other spools began to rotate, causing the braid produced to be imperfect. I overcome this difficulty by applying the driving-gear at different points of the circle of cog-wheels H.

In the accompanying drawings the driving gear is applied at four points of the circle; but, if desired, it may be applied at more points or less, according to the size of the circle of cog-wheels.

In Figs. 1 and 2, )l is the driving-wheel, which, by suitable gearing,is driven from the drivingshaft. Said wheel M is engaged with a wheel, M, on the same shaft with the wheel M engaged with the wheel N on the same shaft with the beveled gear N engaging the beveled pinion O on one end of the shaft 0, on the opposite end of which shaft is mounted the beveled pinion O engaging the beveled pinion l, fixed on the shaft P, which is at right angles to the shaft 0. Said shaft P carries the beveled pinions P and P of which the former engages the beveled cog-wheel Q on the same shaft with the cog-wheel Q, engaging one of the cog-wheels H. The beveled pinion l engages the beveled pinion R on one end of the shaft R, carrying at its opposite end the beveled pinion R engaged with the beveled cog-wheel S on the same shaft with the cog-wheel S, engaged with one of the wheels H. The beveled pinion P is also engaged with the beveled pinion T 011 one end of the shaft T, carrying on its opposite end the beveled pinion T engaged with the cogwheel V on the same shaftwith the cog-wheel V, engaged with one of the cog-wheels 15L Like cog-wheels are also provided in the opposite end of the shaft P. The circle of cogwheels H is thus driven from four difierent points, and there is hardly any perceptible lost motion in said train of cog-wheels H, and thus the braid produced is very perfect and uniform. The braid-winding mechanism of the usual construction is driven from one of the cog-wheels H.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of plates having crossed serpentine guide-slots, spool-spindles movable in said guide-slots, wheels for conveying the spindles, a series of engaged cog-wheels dis.

posed in a circle for operating the wheels that convey thespindles, vertical shafts disposed at different points within the circuit of engaged cog wheels, actuating gears on said shafts engaging certain of said cog-wheels, beveled gears on said shafts, a diam etrical shaft provided with beveled pinions at its opposite ends for engaging two of said beveled wheels and with a beveled pinion near its center, a main actuating radial shaft, as 0, provided with a pinion, O, at its outer end, which meshes with the transmitting mechanism of the driving-shaft, and with a pinion, as 0 at its inner end, which meshes with the central pinion of said diainetrical shaft, and an auxiliary actuating radial shaft, as T, provided with a beveled pinion, T, at its inner end, which also meshes with said central pinion of the diametrical shaft, and with a beveled pinion, as T at its outer end, which meshes with one of the beveled gears on one of said vertical shafts, substantially as described.

2. The combination of plates having crossed serpentine guide-slots, spool-spindles movable in said guide-slots, wheels for conveying the spindles, a series of engaged cog-wheels disposed in a circle for operating the wheels that convey the spindles, vertical shafts disposed at different points within the circuit of engaged cog -wheels, actuating gears on said shafts engaging certain of said cog-wheels, beveled gears on said shafts, a diametrical shaft provided with beveled pinions at its opposite ends for engaging two of said beveled wheels and with beveled pinions near its center, a main actuating radial shaft, as 0', provided with a pinion, O, at its outer end, which meshes with the transmitting mechanism.of the driving-shaft, and with a pinion, as 0 at its inner end, which meshes with one of the central pinions of said diametrical shaft, an auxiliary actuating radial shaft, as T, provided with a beveled pinion, T, at its inner end, which also meshes with said central pinion of the diametrical shaft, and with a beveled pinion, as T at its outer end, which meshes with one of the beveled gears on one of said vertical shafts, and a short shaft, as R, provided at its inner end with a second pinion, R, which meshes with the other central beveled pinion, and at its outer end with a beveled pinion, R which meshes with the beveled gear on another of said vertical shafts, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
