.i Beit known ,that LJAS. A. Bam, ,of

Canto-Ii, 4fn the countyofiNorfolk and'State.`

of Massachusetts, have invented certainnevv andluseful Improvements Braiding and` Plaitlng Machines, of` Which the following" isla full, clear, and exact description, referi ence ybeing: ,had to .the annexeddrayvings,

making .part `of specification, Which- `@Figure` lis an isometric view ofthe machine. Fig. u2 an end view" lof `one ofthe bobbins,` `the f parts immediately connected therewithbeing.seenin elevation. -`Fig. 3 is a plan yef .the 1parts connected with the -drawingoff .motign` Fig. ,a a of the main body `of the lmachinethe bobbins y and plate, by which the lmotions"ofthe bobbins are governed, the guide plateybeing operated by `the bobbins themselves, by the use .of which the ,great friction which `has heretoforeuoperatedgso injuriously` in machines ,of

this character is `measurably avoided, ,and

themachinetselflis greatly simplified..` n i Mylinvention also consists incertamimprovernents ,in the details of the machine which will ;bemere @fully described and claimed hereafter.

To. enable others skilled in the art to make and use my invention :I lwill proceed lto de-l scribe the method Which I have adopted of carrying i it out, setting forth first: the 'genferal featuresI of-themachinerfthen the individual improvements ,which I liaveadded theretouand lastly 4 the combined operation of` `all "the parts. n

A is the lower plate, B the uprightposts, and C the upper plate `of theanachine, D

the exterior, and D the interior guide plates are the shafts which support the roses or bobb'in carriers; these carriers consist each of two parallel plates F and G, secured to the shaft E a short distance from each other,the former being of larger diameter than the latter and having upon its periphery notches a, ofa suflicient depth toaccommodate the shafts of the bobbin holders.

`Upon every alternate carrier the larger plate F is placed upmost, and 'upon the others it is beneath as seen in Fig. l, and they .are so arranged that the peripheries of contact lor* very nearly `so` `Withl fthe periph-1 eries `of the "smaller plates ofthe `ladjvacent carrier. The shafts fE are allgeared' tofirst `In over K extreme ends. i n y n The bobbin holders Aa-re constructed `as; follows: N, FigQQlis the shaft or spindle to which the plates `b and o areattached; these plates lit-one above `andthe other, be-

the .plates `Fr and ,Grof the bobb-in` ,carf rier, and thus .assist in .retaining the bob#` bin holders Vin `place.` l

[d isa concave disk or platettted l to the Vstem of ythe bobbin holder passes through a hole in its center. 'fj y f .are Het ispn'e's thepnd'sf 0f lwhCh are secured tothe plate CZ as seen in Fig. 6 and through `Whichjthe end of the shaftN passes, the screW gfgserving vto; ,confineA the "diskjd tothestemN. f u' "h are the sidenstrlapsl of `the which are made in one piece [and `are Securedto the disks d and thus connectedwith the stem ll\lthrough the mediumfofthe i Springs f, as seenln Fie-f1s'thsestrars. are bent around each otherl at their y extremities Sofas tOfOrm :feriiaor Srfnaedeslk, i threush whhthe thleedfwmthe bebbn passes, and thus `a `uniform and unvharying tension isput upon it.` y z 1s` a stretcher or box which `servresftogkeep each other `and the forceps closed. .i Thislpeculiar construction of the bobbin @holder enables it to bend o-verto oneside ,andthe othervas itis ,carried around by` theroses, the spring connection between the stem and the `sidestraps ofithe bobbin holder allowing the latter Ato yield `as" thetensionjuponthe forceps varies; andthnsA thethreadisnot gether by the cogwheels one orniorefof n, them beingdrivenby a'band lfrolnfa around pulleys upon their the sides of the bobbin holder apart ,from

needlessly unwound or injuriously loosened the one -justfdescribed bya vibrating.' bar.

represented by the line n` in Fig. 5. This barisipivoted at-the point 0 to the frame .of the machine, and is connected with theUeX-4 terior plate at p, and with the interior plateI` at g; by this means the two plates arecausedj to move simultaneously and in contrary directions. The operation of these fplates and the motion of the bobbins may be illustrated by the diagram Fig. 5in which the red lines represent lone position of theplates and the black linesthe other. lThe path of the bobbins -may bevrepresentedby the broken blue Y lines commencing with the plates in the position represented in black lines,` the bobbinsbleing retained upon the roses by the plates b @,Fig 2, and the stem N projecting below ,theplates D Dr by which they are guided,v in theirvv paths, and kept closely pressed upon the yperipheries of the carriers. Starting Withthebobbins in 'the position represented in` Fig. l, three of them are at l the points 7' Fig. 5 proceeding inthe direction of the arrows at these points, and three of4 them atl .the points sproceeding in the contraryfdirection. At these points the bobbins being vcarried by the roses in circular arcs, strike against the movable plates at the points r and s and throw them into the position represented in red lines. The bobbins continue until they arrive at 1 s, when theirstems N again move the plates into the position indicated ,in red, and thus the progreses of thebobbins and the vibration of the p latesncontinues. e

Pis a reel which may be used to carry a cord whereit is desired to introduce such intojth'ecenter of the braid. Thecord from this reel passes beneath the platel AV up through the tube R Aand the braid is formed around it by the strands from the bobbins. Sis a disk upon the-top of tube Rv, the object of which is as follows. As the bobbins` passin toward the'center of the machine the strands'jare. liable to become so loose as to produce an luneven braid; to remedy this n is the objectof the-disk S, which is made of such dimensionsand placed at such a distance above. the bobbins that they shall pass beneathit, and thus the strands are distended over the ends of the disk, and prevented Yfrom becoming injuriously loose.

This contrivance in conjunction with the springA inthe ,bottom`4 A`of 1the bobbin" holder which allows the latter to yield as it passes the exterior of the. curve, greatly conduces `to the regularity and' evenness of the product of my machine.

tom of the tube T whence it is conducted oft' over: suitableI` rollers and, drawn off by an appropriate contrivance at U and delivered to the reel W. f

Y is afrod which ismade to. bear against the finished braid as it comes --from the 'drawingoff 'wheel U, and regulates its delivery `to the reel. As these however are old devices, and form no part of my present inf vention they n eed not be particularly described. 1

Z is a flat springwhich carries a rollerover which' the Vfinished braid is `drawn as it passes out of the machinebylwhich means a constant yielding tension is ,put upon the braid, one half ot' the strands being alternately tightened and loosened, 'as the bobbins revolve. through opposite portions of vtheir paths, and a'much morev even.

braid is produced than where a uniform tension has been placed upon all'the strandsas they leave the ,bobbins l What I claim as my invention 'and 'desire to secure by Letters'latent isl 1 l. The above describedmovable guides D, D, constructed and operating in the manner and for the purpose substantial-ly as described.

" '2. I claim the methodherein-described of constructing the bobbin holders, the'. parts I which carry and guide the thread-being connected with the stem by means lof springs f, which enablesthe bobbins to yieldwvithout Thr-braiding is accomplished at the botpermitting the strand tof render too freely.;I ""f" 3. And I also claim in combination with the above method of constructing the bobbin holders, the herein described method ot drawing -oif the iinished1braid over the .spring plateZ. p

et. Iy claim the disk, S operating in the `manner substantially as described and :for ,the purpose set forth.
