ToaZZ whom/ it may concern.-

Be it known that we, WILLIAM TERRY and FESTUS RAWNSLEY, both citizens of Great Britain, residing at Bradford, in; the county of York,Eng1and, have invented certain new and useful Improvements in Looms for-Weaving Pile Fabrics; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has reference to looms, which *we propose to adapt by a new form of apparatus for the purpose of weaving looped pile fabrics, such as hearth-rugadoor-mats, imitation-skin rugs,and other like fabrics.

In carrying out our invention we employ.

warp and weft of cotton or suitablematerial for forming the back of the fabric, while the pile of the fabric may be composed of a warp VVe' also mount a suitable number of' blades or of worsted or other suitable material.

other form of instruments upon a shaft situated behind the sley or going part of the loom but independent 'of it, such blades passing through the reed, a dent of which may be removed to permit this to be done. These blades are triangular in shape and are arranged at suitable distances apart upon the shaft which carries them, and upon the shed being formed the shuttle is sent across the loom, passing under the triangular-shaped blades and through the shed, after which the healds which operate the pile warp or one or more combs are made to move laterally by cams, spiral springs, or other contrivances, so as to carry a thread of the pile warp over or across the top of each blade, after which the shed is closed, carrying the warp down over the knife, forming a loop thereby, which is afterward secured into the fabric by the weft and the beating up of the sley in any wellknown manner.

In order that our invention may be better understood, we will now proceed to describe the same more fully, and for that purpose make reference to the accompanyingdrawings,illustrative thereof, wherein- Figure 1 is an end elevation, partly in section, of. a power-loom, having our improvements applied thereto. Fig. 2 is a cross-section thereof, and Fig. 3 is a front elevation of some of the parts shown in Fig. 2. Figs. 4

the pile of the'fabric is supplied by the bobii bins G, passing around drum G and under rod G carried by lever-arms G mounted on shaft2, one ateach side of the loom. The saidlever-arms are operated by the lever G also secured-on the shaft 2. oted to the lower end of the lever G and to 4,-projectingfrom the frame A. The lever G carris aroller 5, which is operated by a cam 6. mounted on the shaft R (Shown in heavy dotted lines and A rod G is pivthe upper end of a lever G pivoted on a pin H represents the breast-beam, and I the I taking-up roller. Behind the sley-board is a horizontal rod J, supported by brackets J,

bolted to the frame-work A, upon which rod J are mounted any suitable number of triangular-shaped plates or blades K, the forward points of which pass through or'between the dents of the reed L, the said plates being secured on rod J by a key or other means,.

washers of suitable thickness being employed to separate each blade and the whole series of blades being kept together and tightened up by nuts J (See Fig. 3.)

In front of the heald-shafts M is a horizontal bar N, to which is attached a small grate or comb 0, between the prongs or spaces of which each thread of the pile-forming warp enters, as shown clearly in front view, Figs. 3 and 4. The pile-forming warp, which is governed by heald M, is made to enter between the prongs of the said comb at every pick or every alternate pick or every third pick or otherwise, according as the pile is required to be fine or coarse, this being deter- ICC the other endis pivoted to the frame A. One thread-of warp also lies in the space between each two adjacent blades K, so that when the shed is opened the bar N, together with the comb O, are made to move endwise or laterally in the direction of the arrow P in Fig. 3, the effect of such endwise movement of the said comb being to cause each warp-thread to cross each blade, so as to pass onto the other side thereof, as shown in Fig. 4, and simultaneously with such lateral movement of the bar N the shuttle is sentacross the loom and the shed closed,in doing which the pile-form ing warp, which has been crossed over the blades, is formed into a loop over each blade,

as shownin 5,-the length of warp required to :form the loop being drawn off the spools or bobbins G by the oscillating vmovement'of :the lever-arms G so that when the free ends of thejbladesare raised, as shown in fullline in f Fig. 12, the pile-warp, which has just been; drawn =off-the spools by the lever-arms G is; in 'a slack condition, and therefore can be. drawn up by the upward movement of the,

blades, so as-tollengthen the loop. The crossing of the warp and :the introduction of the weft makes the loops secure in the fabric, as

will be-well understood by those conversant with weaving. It will bevu-nderstood-that by the beating up of thersley toward the breastbeam'at'he newly-formed loops will be :Carri-ed forward tothe'extreme poin'tofthetriangular bladesK and within reach of 'theooscillating stripping-brush Q which strips the loops from i the blades, which at this particular time are elevated, as shown ,in Fig. 2. The blades K, which are fixed upon the horizontal shaft J, are {elevated or caused to rise bymeanso'f the said shaf tJ beingmade to rock, which .isef

fected by means of lever-arm Rand-the connectin-g-rod sR: attached tolevers Rtand Rithe latter'of which :is-oscillatedbymeansofaboxcamlfl on theshaf t R. (Shown in light dot- 1tedlinesof Fig. 1.) 1A .roller 13 engages with blades to rise to variousheights, which is-de-. termined by the extent of movement made v1 y the arrangement of cams and levers. The

stripping-brushQ is made to reciprocate toand from .the points of the blades by means of :anothercam 14, fixed-on the shaft R, (see Fig. -1,) and levers and rods S, S, and S the latter of which works upon a fulcrum S and isconnected to the end of a lever-armS, carrying the brush it) and also a friction guide .or-zbowl a. In order to give the necessary ment of lever St The endwise or lateral movement is given to the bar'N and comb O by means of bell-crank lever T, (see Fig. 3,) operated by cam T, madeto revolve by hooked finger U, connected to lever U, Fig.2, which is operated .at every backward movement of the sley by finger U attached to sley,.-com- :ing into contact with the bowl on the up per end of .lever U, such 'movementdrawing down'the hooked finger U, which engages with a stud on cam .T' and rotates it a distance equal to the distance between the studs on said cam. The levers last mentioned are brought back in the opposite direction by means of the spiralrsp-ring U (See :Fig. 3.)

It will begseenthat at every revolution ;(or at every alternate or third revolution,;as previously determined) of the crank-shaft the pile-forming warp is passed over the blades and that loopsare formedand made secure by the weft, thelength of such loops beirrgdetermined bythe depth of the blades. When a longer loop is required than the depth of the blades :will allow, thesaid blades are made to ri-se after the-Warp :has crossed over them, which is effected by givingarocking motion to theshaft upon which they are mounted, as previously described. The loops thus made, if required, may be severed by means of a knife formed at the upper end of each blade, or the loops may be severed in any other convenient manner.

By the apparatus above described looped pile rugs, door-mats,-.imitaLi011-skin rugs, and other pile fabrics can beexpeditiously manufact-ured, andaseach loop is-interwovenwith the fabric it will be-fou-ndv-ery durable.

WVe claim as our invention-- 1. In a pile-fabric loom, the combination, with a shaft arranged :at the middle portion .of the warp, of a seriesof knives projecting from the said shaft in line with the warp and means for oscillating the shaft, whereby the free ends of the said knives are raised vertically and adapted to increasethelength of the'pile-loops, substantially as set forth.

2. In a pile-fabric loom, the combination, wit-h a series of vertically-oscillating knives arranged in line with the warp, of a vibrat- .ing comb arranged crosswise of the warp,

whereby the pile-threads are moved laterally over the knives, substantiallyas set forth.

3. In a pile-fabric loom, the combination,

IOO

with a series of vertically-oscillating knives arranged ,in line with the warp, of a reciprocating stripping-brush adapted to remove the jecting guide, and inclined planesadapted to 15 control the motion of the said guide, whereby the brush is adapted to remove the loops from the points of the knives, substantially as set forth. 1

In testimony whereof we affix our signatures 2c in presence of two Witnesses.
