IMPROVEMENT 1N ,umriss-moulure.

Be it known that I, JAMES WALDIELoiIpswich, in the county of Essex, invented certain Improvements *in Machinery for WeavingfStriped Hose, Snc., clear, and exact description,.reference being had'to the accompanying drawings, tion,in;which l' u Figure 1 is a perspective view of :ny-improvements applied to a machine for weaving striped hose.

Figure 2 i`sa transver'severtical sectionv through the'centre of the same. I r

Figure 3 is a perspective view of the notched Hengel-wheel, with-its weighted arms Vor levers, the wheel being revolvedlbyfthe drivers, so as to cause the arms or levers to engagent therequired'times with the several threadcarrying guide-hars.

undState of Massachusetts, have o f which the following. is a full,

"making part of' this specifica.-

her in' which I have carried it out.'

` In the said drawings, A is th'e framework, in the top of which is formed a grooved way, a, for the table B to slide,therein. Rising from each end of thistable is e. standard, b, to which is` secured the cord, which passes 'over guide-pulleys, and around the slur-wheel, which is operated by a treadle under the machine, for pro- To enable others .skilled in theart to understand land use my invention, will proceed to describe the man? ducingthe alternate forwards-nd back inotion required. T h'e above-mentioned cord,guide-pulleys, slur-wheel,

`.and treaidlc, forming no part of my invention, and belngof common construction, are not represented Vin. the

1 The tops of these standards b are providedrwith o'pen slots, lwhich rests e. ber, C, the enclsof which are Arounded or bevelled o, nsshown at 5, tig. 1, in order th44 t they may ride up over the -rounded surface, 6, of

'stops D, placed: one at each-'end of the top of 'the framework. To opposite sidesof thesliding bar C, at 7,.are

stops forl preventing the lever ordriverfrom turning the ratche secured the bent. arms E, to the lower portions, c, of each of'which `ispivoted, at`8,` the lever or driver F, which isrpushed forward by the sliding bar C, so as to engage with the teeth or notchesd formed inthe periphery of a wheel, Gr,- which serves as a ratcliet,`and is placed underneath or 'forms the under siderof acum-wheel, H, which iits loosely-upon a short stationary shaft or stud,'I,-.iproceeding up from the table B.

The sliding bar C sprovided with tivo pins, e, which regulate the throw of the sliding ber -C,and serve as t-wheel G more than the distance between two teetlnoiI Each driver, F, is providedwitha spring at itsiback, to insure its engaging with the ratchet.

The top of the short studI is cut uway'for the reception of a slotted bar, K, which rests upon the cam- .wheel H, in a. direction transversely with the machine, a pn,f, passing through the stud and slot 'g,\`to allow it .pieces l m n,

to be slid hack and forth, in manner and for a purpose now to he explained.

On suitable ways, L, M, and N, in front, and that, O, at the back of the machine, rest the several bars, L M N O', to which thc thread-guides: h 1I j lc, carrying the -diierent-coloreed yarns,lure attached, all of the thread-guides on the same bnr carrying the same colored yarn, diiferent from that carried by the guides on each of the other respectivevbars. l inn are forked pieces, secured to and projecting vertically up from the 'several bars L M N O.

One end of the slotted bar K is provided with'c. projeotion ,'p, which is .madejto engage with the forked and thus cause the several bars L M N O! to move backend forth o'u theirwa'ys, L M N O, and curry the guides h j 7c, only one bar, L M N"O audits seriesfof guides, (carrying the desired color to be 'woven,)being operated at'a time.- The manner inl which the slotted bar K. is thrown into connection with either of the forked pieces'h z'jrlc, -to move the bar and guides carrying the color required, will now be described.

To the end of the vslotted bar K (opposite that bearing the projection?) is secured one endof a spring, r,

' the other end of which is fastened tothe pin f, passing through the slot g. From the under side of the slotted har projectsa pin, s, Vwhich bears againstthe'periphery o r exterior edge of the cam or eccentric, H.

Y As the driver or drivers engage with and turn the ratchet G, the cnm-wheel is simultaneously revolved 2 sass? thereby, and the slotted bor K, through the connections above described, is madef't'omove `in the direct'ionof 'the arrow 5 bythe recoil ef the spi-ingr, so ns to engage with either of the forked, pieces lm n, on the' guidebars LIM N', (at the front of the maehine,-) su ciently long* to weave the desired'numbcr of courses, of the color required, whilothe bar K is pressed forward in' tho dir'cctionof the arrow, so as to engage with the forked pieces, (not shown in the-'drawings,)'but attached to the bar .0, slidingvit, and carrying therewith the thread-guides k, by the 'periphery of the cam H, pressingl theV pin 's in'this direction against tho' resistance of thesprng r. -4 I y The periphery of' the cam is-provided with notches t; the distance between which is such, that, as the coni; revolves, the sliding bar,will continue its connection with any particular guide-bar suicien'tly long to allow i its Abeing slid back andi'orth to weave the desired number of courses of that color of yarn.

i By the above-described construction, I ain enabled, bythe employment of one driver, to weave any number of even courses of three or four eoloi's. The cam-wheel-may be cut so as to be adapted. for making any number of courses or colors'desired. In iig. 3 is shown a fiatcireular disk, P, the outerperiphery of, which is provided with n, number of teeth, u, corresponding to the number of courses, and serves a similar oiiice tothat of the ratchet-wheel G, while its upper surface is provided with four anges, e wx y, which extend partially around' the circumference of a circle ofthe diameter required, the portions'of the circumference between' 9 and 10, and 11 and 12, being smooth, and Hush with the upper surface of the disk; Theseflanges o w x y are provided with notches, e, the flanges so constructed serving to take the place of'V the 'cam-wheel H. This disk Plits over-'a stud, Q, corresponding to that marked I in iig., 1,' and is revolved by a single 4driver or a'pair of drivers, alter- ,nately engaging within `its ratchet-teeth, u. R R are four levers,lcorre'sponding to the number of Ranges o zo a: y, and, consequently,to*that of 'tho colors' to be woven. lThese levers R are of unequal .lcngth,aan'd are pivoted at one end4 to the stud Q, while their othercnds are provided with projections, 13, vwhich fall at stated times into a `notch in an arm rising from orforming a part of the guide-bar to be moved.

The under sides of these levers are also provided with other projections, 14, which, as the circular disk P is yrevolvgd under them, hear oil-the Bauges uw z y, and drop at the required times into the notches z, thusl causing, the projections 14, through the forlred'pioces attached thereto, to engage with the guide-bars, only one of'which is operated at once. The'distanee between 'the notches z is'such as to insure the projection at the end of its lever being engaged just long'enoug'hl'to 'make a singiefcourse or any odd' number of courses,'of.the color.

required, after which another leverfis made to engage with-another sbar, to produce any. number of odd oreven.

coursesof any other color, both'dr'ivers F being employed. When the cem-wheel H, with its ratchet, G, is used in connection with a single driver, F, any number .of even eourses'of three or four colors may beweren, evenv courses of two colors only lx'avmg been previously made by the'use oi'a single driver. It is evident, that by increasingthc number of-langes of the flat circular wheel-ordisk P, and the numberof levers'R,-a'greate1' number of guide-bars may be operated, so as to weave-tive; six, or morecolers, and -othcr goods. besidcslhosc may be woven, without departing from the spiiit ofl my invention. i

Whena new coloris to bewove'n, no one of tho levers engages with a guide-bar while the slide, is. going back inv its groovedway a, for the purpose of taking the new color, which operation isi'ftcehnically termed al drawback. v i

' l G'Zazms. What I claim as. my invention, and `desire to'secure-by Letters Patent, is 'f A- ratchet-wheel, G, vwith'aI single cam'or ceceutrie,'-H, operated by a single'driver, I", for weaving any even number of courses `othrce orlfour colors, substantially as set forth- I also claim a ratchet-wheel o'rdisk, I, provided with three or more flanges, constructed as described, in

combination with `n. corres ondin f number of. levers, R It 4und o eratcd `b itwo' drivers, F for weavi'nfr edd or P s P y a a evencourses of'three or more colors, substantiallyas and for tho purpose specified.,
