LOOM FOR WEAVING DOUBLE-FILE FABRICS.
Application filed September 5, 1923, Serial No./661,056, and in France February 27,1923.
The present invention relates to devices for making figured Jacquard velvet 1n one or more colours in double pile velvet ribbon looms weaving severalpieces at once and Q also in double pile velvet fabric looms.
The accom an in drawin shows an em- P y ,2: a: bodiment of a loom mechanism according to Fig. 6 is a plan View thereof from above.
Fig. 7 is a plan view of the lower hole board through which the threads from the bobbins pass. v 1
Fig. 8 is a perspective view showingthe members which connect the two sides ofthe framework and the tension weights for: the threads as they pass from: the bobbins to the pile feeding device.
C I"eeZ.'-The creel carrying the set of b0? bins consists of a wooden bar 1 on which are fixed spindles 2 to receive bobbins 3. Fig. 5 shows an embodiment of a set comprising two spindles .wit h their bobbins, an empty spindle and a small, spindle for holding the spring which acts upon the next adjacent bobbin for a' purpose to be later set forth. I g The number ofbobbins may vary both in the length and in the breadth of the creel, according to'the dimensions of the fabric to be manufactured.
At the base of each spindle there is-a helical spring 4, the. lower branch 4 of which bears against the c'oils'of the spring on the next succeeding spindle, while-the upper ''branch 4" bears a ainst the next ad'acent bobbin or against the next adjacent spindle itself when it carries no bobbin.
'The threads from the bobbins which are 'maintained under tension by the'springs 4:
are directed towardsthe lower part of the bar 1 where they traverse guides formed in a lower hole board 5 which is fixed in an inclined position at the end of said bar. On leaving the guide board, the threads pass through the eyes of tension weights 6 (see Fig. 8) and are then directed towards the pile feeding device.
A transverse member 7 which'conne'cts. the two sides of the framework, prevents the tension weights from being-carried forward with the threads.
Pile fee/Zing choice-The pile'feeding device consists of two cast-iron supports 8, 8, each secured by means of a bolt 9-to a cross piece lO'at the rear of theloom. The ends of'the upper fixed member of a gripping device 12 are also fixed by bolts. 11 to the upper part of the supports 8. A rubber band 13 isfittted in a groove extending throughout the length of the lower edge of the upper member 12 of the gripping device.
'Below the fixed upper member 12, of the gripping device there is a movable member 14. V The members 12 andla act like a vice to hold the threads. The ends of the movable member 14 extend into grooves formed on the inner faces of the supports-Savhich thus serve'as guides for said member. On the upper edge'ofthe movable member 1-1 there is a wooden covering 15 secured by screws.
A band of cloth l6, coated with pulverised glass or emery, is glued to the covering 15 to ensure theadhesion of the threads when upper member 12 and the lower member 14: e
of the gripping device. are brought together- At one of the upper corners andextending V the full length,,of the wooden covering 15 is a recess into which .is fixed a roundiron or brass rod 17 projecting slightly above the levelof the upper edge of said covering, in
I order to prevent the pile threads resting on the clamp band '16 from being frayeddriring the upwardmovement of the movable member'll of the gripping device. '7
On the driving shaft18 aremountedtwo cams 19, 19 secured by set screws. "These cams act on levers 20, fixed on a shaft-21 to which is imparted an oscillatory movement in order to reciprocate rods 22, 22, mounted at the end of the levers 20-.
At the upper end of each of the rods 22 is mounted a connecting member 23, of, which members 23 the upper ends have screwjthreaded connection with the lower regulation of pressure exerted by the member'l l against the rubber band 13 'of the fixed member 12.
l The driving shaft 18 at one end outside part of the member 14, thus providing for the frame also carries a sprocket wheel 24 which transmits its movement of chain to another sprocket wheel secured to one end of a shaft which actuates a presser bar On tn. shaft 26 are fixed two 4'1. S arms 2? the ends of which su abort the bar 28. By this arrangement. the shaft 26 is rotated and trasmits its rotation to the bar 28.
Made of ccz ioa. hen the pile thread reaches the extrehe poin travei,
the cam 19, by means of the lever 20 and of the rod 22, forces the member 21g inst the r be: band 13 of the member 1 The clamped, the presser in the direction shown '1), bears on the pile by the arrow w o when is stretched and consequently tension weights to rise. The

front of the batten, then i t then descends, pass .i to (i f. ascends through the m nt 32 see to be cm l q y the kin-re The p le threads hanging down below the under of the -ric, which are cut by the knife, cannot unravel during the weaving because they are clanpcd at the angles of the opening 31 by the tension of the fabric, and the loom consequently is capable of weaving designs of great length.
This mechanism, moreover, has the advantage of eliminating the recoil of the piece, which recoil is usually produced by the batten and consequently makes it possible to obtain a better out.
Having thus described the nature of the said invention and the bestmeans I know of carrying the same into practical effect, 1 claim i 1. in a loom for weaving double pile fabric c ibo'dying a creel from which the warp threads to form the fabric are drawn and heddles, means for gripping the threads at the end of each movement thereof to the lied- 1 said gripping means comprising .a lire-d member and a movable member tetween which the threads pass to the leddles, and a rotatable cam for moving said movable member toward said fixed member.
2. in a loom for weaving double .pi'le fabric embodying a creel from which the warp threads to form the fabric are drawn and h ,ddles, means for gripping the threads at the end of each movement thereof to the heddles, said gripping means comprising a pair of relatively movable members between which the threads pass on their way to' the heddles, one of said gripping members-being provided on its working face with a fabric covering raving hard particles embedded therein, a rotatable shaft, and cams carried by said shaft for actuating said gripping means. y
A gripping means according to claim 2, wherein a bar ofs ubstantially round cross section is secured to one 'cornerof the working face of the fixed gripping member.
l. In a loom for weaving double pile fabric embodying .a creel from whichthe. warp threads to form the fabric are drawn and heddles, means forygripping the ti'ireads vat the end of each movement thereof to the heddles, said ripping means comprising .a pair of relatively movable niembersbetween which thre ass on th'eir way to the heddles, 'e V able shaft, cams carried by 'd sha for actuating said gripping .n'ieans,1and a presser bar "associated with i said gripping means for applying tension to the ithrear. s when clamped between said gripping men'ibers, said ;PISS6F bar being actuated from said rotatable shaft in timed relation towthe movement of the gripping members. V
in testimony whereof I have signed my name to this specification.
