Leners Patent No. 111,325, aaa January 31, 1871| IMPRoVI-z-MEn-r'IN cARrETs.

jThe Schedule referred to in these Letters Patent an making parl: of the same.

full, clear, and exact description thereof.

The drawing is a longitudinal'section, showing the collocation of the threads which forni the carpet, and also the pile-wires in place in the fabric. They are not intended to represent the threads as of the proper size, or as driven up in a finished carpet, but are intended to aid in'dening the character of the fabric and the preferred manner of making the same.

By tapestry carpet I mean a pile carpet in which the figure is formed by means of a parti-colored warp, or, A

in other words, a warp each of whose threads is printed or dyed of different colors, the colors and their relative positions being so adjusted that when the .warps are woven they shall produce the required figure without any aid fromla Jacquard or any of its substitutes'or that all the printed warps show at each pick, and, consequently, that comparatively few'warp-threads are used, arcfnot so thick. and elastic, feeling when tread upon, as Brussels or Wilton carpets, and consequently wear out sooner.

-By my invention I havc'remedied this defect,

and have, at the same time, madethe.carpetreversible, so that it may be turned when ,partialiyworm being, in this respect, like the ingrain, and this feature much increasing the duration of the carpet.

I make these carpets of a st'nfiing-warp, a linen or binding-warp, and of two printed or colorwarps, one for each face, andof weft threads, and I prefer. to mount the looin with vfive harnesses (or five leaves) or -frames of heddles. One frame contains and 'governs the warp marked c on the drawing, being' the upper clor-warp, or the warp forming the pattern and upper surface (as woven) of the carpet. f Y Another frame contains b, the lower color-warp, or

`warp forming thel pattern and lower surface (as woven).

of the-carpet. Thesewarps may be wound on -thc 'same or separate beams; I prefer the latter.

Another, or third framc,.contains and governs onehalf of thc linen warp, being that p rtion marked C 4in the drawing.

A fourth frame containsand governs the other half of the linen warp, marked (l in the drawing;l and A fifth frame containsandggoverns 'the stallingwa-rp, marked c in thedrawing, and with the warp's thus drawn through the heddles the fabric may be woven, as -follows First, the warp a, see iig. 1, is raised into the 11pper plane of the shed, warps c, ll, and e are held in the cent-ral plane, and b is lowered' into the lower plane of the shed, this -being the disposition of the warps shown at theright-hand end of iig. 1, and forming two se1ni-sl1eds.

Two pile-wires, j" and g, are now inserted and driven` up to the fell 'of the fabric by the reed.

Second, thev warps c, b, and e are all raised to the upper plane; c remains up and dis depressed into the lower plane,'and. a pick of weft-thread is then'shot, see right-hand end of Figure 2. Third, c remains up and 'l down, and a, b, and care lowered into the lowerplaue; another pick of weft-v thread is then shot, see right-hand of Figure 3. Ilolnf'thxsuch harnesses are moved as 'will bring all thc warps again into thelirst position, 'and pile-wires are again inserted.

Fifth, suoli4 harnesses are moved as will bring the warps into the planes as in the second position, save that warps c will be down and d up; then-a pick of weft-thread is thrown. Sixth, the warps are caused to assume the third position, except that c will be down and l up; then a pick of weft-thread is' thrown.

Seventh, the warps are again asin position first, and all the other positions repeat themselves till the vcarpet is woven'.

\Vlien the carpet is thusmade there will bea pat -tern and a pile on veach side thereof. The patterns may be-thc same or di'ereut. The wires are to he drawn, and' the pile may be cut by the aid of .a knife on the end of the pilc-wire,ias is well understood in cuttiigpi'lefabrics, or left uncut, as desired.

The same carpets may be woven with all the warps either up or down atV each pick, and one 'pile-wireonly placed at a time; or it may be woven with two shuttleraces and shuttles and two picks of weft-thread thrown at the Sametime, one above and onebelow the stuif-` ing-warp in'the central plane. I also intend at times to shoot additional picks of .weftvthread between the rows of loops, and I further intend, atV times, to add an additional frame-of harness.V or leaf of lieddles and divide the stufling-warp, so that each half thereof shall be governed by a different leaf of heddles, andwhen the loom is thus mounted vI intend to make one or more sheds of the stuffing-warp after the two pile-l wires are placed, and before the next two are placed;

same. ,-v

The carpetthus woven will be stronger and thicker than that of which it isa mocnncaton, and the stuffing-warp becomes, for the first time, something more the upper the other for the lower face of the finished fabric, cach forming a pile.

Second, alinen or binding-warp.

Third, a stuffing-warp.

Fourth, weft-threads. A

Fifth, a pile 0n both sides or faces, either cut or uncut, or` partially cut and partially uncut, although I have stated that the color-warps are one for the upper, the .other for the. lower face of the finished.

'I claim as of my' own inventionv l1. As an article of manufacture, a carpet made up of two parti-colored warps, a linen warp, a stuffing-warp, and weft-threads, when the same is so composed, substantially as specified, that the fabric has a pile either cut or uncut, or partially cut and partially uncut, upon both faces. v v

2. As au article of manufacture, a carpet presenting a pile either cut or uncut, or partially cut and par tially uncut, upon both sides thereof, when the same is composed, substantially as specified, ot'- two particoloretl warps, a linen warp, a stning-warp, and weftthreads, some of which latter are shot between sheds formed of the stung-warp, substantially as described.
