IMPROVEMENT 1N BRAlniNe-MAc-HIN'ES. I

The Schedule rolex-red to in these Letters Patent and making of thesnme.

.To whom it may concern l iu Machines for Making Braid; and do hereby deciare the following to be a full and correct description thereof, reference being had to the accompanying drawing making part of this' specification, and to the letters and numbers of reference marked there- J on, similar letters and numbers being used in all the figures to denote the same parts.

The fabric produced by the braiding-machine with these improvements is substantially a union oi' two or more braids, of the'same or diiie'rent colors or maf terials, vjoined, together by interlocking their edges vwhile in the process of making, and is accomplished mainly by making the run or groove that guides the spoolcarriers oi' a peculiar form, and by the construction and position of the driving-wheels and the horns on them, whereby the force .that drives the carriers is applied in the proper direction.

Description of the Drawing.

Figure l is a view of the top plate, showing the shape of the run; also, by dotted lines, the position of the drivers and the horns on them. 1

Figure 2 is a top view of the gearing.

Figure 3 shows a longitudinal section, taken vertically through the centers of the gear-wheels a b c d g;

Figure 4 shows the position oi' the strands of the braid as they are interlocked.

General Description. .A is the top plate, having the run'S, as it is called,

. a vrooveof nearly uniform width, cut through it.

The parts of the plate inclosed by the run are called quoits,and they are held in their places by being screwed to the tops of the studs o o, which are fastened to the lower plate B by passing through it, and having nuts screwed on their ends.'

These studs al hold -the driving-wheels a b c. d g,

l which 'are free to turn on the studs, and are furnished with teeth to -gear together and drive 'one another.

- a e'e" d" 9" are projections on the upper sides of the i driving-wheels, called horns.;

These horns are made of dierent heights;l those on the wheels a and g are high enough' to pass over the horns on the wheels b'and d nextj to them, that they may not hit'in passing each otherkand drive the 'carriers from one part of the run to another. These horns are' m'adc'in; pairs, so as to form recesses between ythem toy receive the studs or lower ends of ,e. The oarners are indicated by the ljf 3.456,7-8in iig, 1. -Thedrivingfwheels being put in motion in the direction lindicated by the. arrows, each carrier in the end circles of the run will be driven around thatjcircleJby its lower end, which projects downbetween the horns on the wheel under that circle. (See g.- 3.)

When a carrier, after passing around the endj'circle, .v comes to the crossing in the run, the width :of that part of the carrier in the run' keeps it in such afposi-A tion that it enters the next circle or oval of the run, y

the horns on the next drivingwheel taking it from. the first one and driving it forward. ff

Now, the run between the two outside circlesis composed o f two circles or ovals, overlapping:each` other in the middle; this brings the crossingsof the ,A

ovale in such a position that a carrier, having'entered the oval, cannot leave it at the middle crossing to en;

ter the next oval, but mustcontinue in the same'iintil it. gets back to the outside circle it started from, Asu

that two carriers starting, one from eaehof. the'outside circles,l at th s ame time, will'pass around each. A other in the middle. (see 4 and 5 in iig. 1,) wherethe' 'ovals overlap each other, and this interlockstheirthreads; and, as each carrierin the outer circle' in its tur'n passes around anotheriu the middle, it 'follows that the two braids are interloched by each strand in its turn. (See iig. 4.)'

When the spool-carriers le'avethecuter circle of the -run theyenter the horns e and e -on wheels b and'd, -whichdrive them forward until they come to the crossing ofthe run where the ovals overlapeach other. Here they arel taken by the horns e" e" ou the center wheel c, which drive theui around the ends of the ovals, the lower ends of the carriers passing inside of the hornsv e and c, betweleu them and the centers of the wheels on which they are, (see fig. 3,) .until they come to the other crossing, where they are again taken between the horns c' and s' on the wheels b and d, and carried to the outer circles -from which. they started. This keeps each set of strands by itself, :excepting at the edges where they are interlooked, and it will be Aseen that any number of sets like the outer circles beorementioned may be joined in the same .way by having the overlapping circlesor ovals placed between them, as above described, and thus fonn abraid of'- strips of ilii'erent colors or materials, either dat o r "circular, as may be desired. ,The dotted lines gto the right hand of rig. 1 show how this extending of the ovals can he made. l

The biaidis drawn up with fcedrolls placed above l. K the spools, in the manner usual in this class of maehines, and not necessary to be" particularly described here, nor have we deemed it. essential to describe more patticularly the upper partof the spool-carriers, with their-tensions, Src., as any of the lusual modes;

What weclaim es our invention iis-'- 1. A ru'u orrlguidng-grooye for the ispool-cau'rierxa,l formed of two circles or ovale overlapping each other so as to foim a circular space between them, substantially as herein shown and described, and for the purposepecified.- Y f '2.'
