TAKE-UP FOR BRAIDING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 447,107, dated February 24., 1891. Application filed June 28, 1884. Serial No. l36,209. (No model.)

To all whom it may concern.-

Be it known that 1, PER J OHAN ALFRED FORNANDER, a citizen of Sweden, and a resident of Brooklyn, in the county of Kingsand State of New York, have invented a new and useful Improvement in Take-Ups for Braiding-Machines, of which the following is a specification.

together, but arranged with the journals in a slot, one above the other, in order to make their weight insure contact between the contiguous surfaces. Another device consists in winding a cord back and forth over and between two parallel shafts geared together and provided at intervals with grooves in which the cord rests, so as to spread and stretch it.

My present invention comprises constructions whereby the position of the take-up is conveniently-adjusted with regard to the braiding-point. The velocity of the take-up, in proportion to the size or coarseness of the cord or band, is varied and adjusted. ferential velocity is obtained between the receiving and the delivering wheels of the takeup, so as to always keep the cord orband taut, and the fastening of exchangeable take-up wheels of various sizes upon their arbor is provided for, so as to gain bearing-surface in proportion to the diameters of the wheels, and consequently to the resistance, so as not to depend, as heretofore, for the bearing on the square fitting into a corresponding central hole in the wooden wheels, which in wheels of larger diameter very soon wearsufficiently to become loose.

In the accompanying drawings, Figure 1 represents a side elevation of my improved take-up in position as when in use. Fig. 2 is a top or plan View of the same, the parts of the braiding-machine being omitted. Fig. 3 is an edge view of the worm-wheel, showing its construction for applying thereto the ex- A dif- I grater.

ceive their motion from the wheel a in the usual manner. The shaft 0?, on which the Wheel a is secured, is arranged in a vertical position within the hollow post B, secured by its flange b upon the table A. Upon the upper end of the shaft a is secured the ordinary worm b, from which motion is communicated to the take-up by means of the worm-wheel O in a usual manner. The take-up is supported upon a double arm D, which, by ahollow hub d and a set-screw d in the casting of the said hub, is adjustable as to elevation, and by turning it, also laterally'working upon the aforesaid round post B.

E is the receiving-wheel and F the delivering-wheel of the take-up. rigidly secured together, preferably by turning them out of one piece of wood, and they are mounted to revolve upon the stud e, secured to the forward end of the arm D. The

These wheels are face of the wheel E is smooth, but the face of the wheel F is ruffled or hasa coarse surface,

so as to hug the cord or band with sufficient is covered by a band or covering f, which for finer tape may be a strip of rubber, and for coarse round cord may be a band of tin perforated and with the metal raised around the perforations in the manner of an ordinary The wheel F is larger in diameter than the wheel E. In the rear of the post 13 or huh (I the arm D has a projection 01 to which is secured, by a bolt g andsuitable bolt-holes, an arm or bar G, provided with several holes g, in which the stud c and bolt 9 are fastened. Upon the stud c revolves the aforesaid worm-wheel.

Vhen required to vary the speed by a different proportion between the Worm and the wheel 0, a wheel of a smaller or larger diameter than the latter may be applied upon the stud c, as by loosening the bolt 9 a little the bar G may be swung away from or to ward the worm b to bring a wheel of any size into gear, and by shifting the bar G so as to bring one or the other of the holes g upon the bolt 9 and securing the latter the proper elevation of the stud 0 may be obtained to always keep the worm-shaft a? in the proper position parallel with the tangent of the wheel 0. Upon the stud c is also fastened to revolve together with the worm-wheel O a wheel 11. This is made of wood and covered with a rough band It, similar to the band f upon the wheel F, and has a central hole just large enough to fit snugly upon the stud c, and the side of the wheel II is grooved at h diametrically across its entire surface, so that when put upon the stud c it may be secured to revolve, together with the aforesaid wheel 0, by moving it up against the diametrical rib c in such manner that the said rib will enter into the said groove h. In this position it is kept by a collar 1, fastened by a set-screw '11 upon the stud. By this construction it is evident that whatever be the size of the wheel H and consequent length of its radius it is held firmly in position, for whether the wheel is large or small the rib c enters the groove 7L throughout the entire diameter of the wheel H. l-Ieretofore I fastened the wheel H by a square hole through its center, ,which fitted upon square stud, which plan of course for wheels of larger diameters did not increase the strength in proportion to the resistance, in consequence whereof the center holes were always wearing out so as to become loose upon the stud. For braids or cords of coarse strands the Wheels H are made of proportionally larger sizes, and for those of finer strands are made smaller.

Referring to Figs. land 2, the strandsjone from each carrier-unite at the braidingvpoint J.

The cord or tape K, formed at the braiding-point, passes up over the small smooth-faced wheel E, thence down and underneath and around the take-up wheel H. Thence (deflected by the guide-pin it passes down underneath the coarse-faced wheel F, and thence over a suitable stationary board or guide-surface L down into a suitable receptacle M. To insure sufficient friction between the cord and the surface of the wheel F, a spring N is secured by a set-screw n to the arm D in such manner that the spring may be turned upon the set-screw to bear with its outer end more or less against the wheel F, after which the set-screw 'n is tightened up, so as to maintain the pressure constant. The wheels E and F being secured together and the pull of the cord being produced by the take-up wheels H, it is evident that the surface speed of the wheel F, on which the cord cannot slip, is greater than the surface speed of the wheel E. Consequently the cord is always kept taut by the rough wheel F, the smooth surface of the wheel E allowing the cord to slide to make up for the difference in ve ocity.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with the take-up-carrying arm D, the suppoi-tingstandard B,shaft a worm b, worm-wheel C, and take-up wheel H, of the bar G, having a series of bolt-holes adapted for carrying the stud c of the takeup wheel H, the said bar being adjustably secured upon the said arm D by the bolt 9 to support wheels 0 of different sizes in gear with the said worm, substantially as and for the purpose set forth.

2. The combination of the supportingstandard and arm, shaft (1 worm b, and the worm-wheel 0, provided across itsside with a web or rib c, with an exchangeable wheel H, having a cross-groove h to receive the said web, and means, substantially as described, for temporarily retaining the said web in the said groove, for the purpose set forth.

3. The combination of a take-up wheel H with a receiving-wheel E and a deliverywheel F, the said wheels E F revolving together and having respectively smaller and larger diameters and smooth and coarse surfaces, and with the shaft 66 worm b, and wheel C, means being provided to keep the cord in contact with the delivery-wheel F for the purpose of keeping the cord taut, substantially as specified.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two witnesses this 19th day of May, 188i.
