LOOP-CUTTING MECHANISM FOR PlLE-FABRIC LOOMS.
SPECIFICATION forming part of Letters Patent No. 758,968,da.ted May 3, 1904.
Application filed July 15, 1903. Serial No. 165,624. (No model.)
To 1 if W 007L067"! to the take-up roll 3, provided with pins 3' in Be it known that I, GEORGE F. HUTCHINS, the usual way.
acitizen of the United States, residing at At the front of the plate 1 is a Stationary 5 Worcester, in the county of Worcester and metal plate or bar A, which extendstrans- State of Massachusetts, have invented certain versely across the loom and is secured to the new and useful Improvements in Loop-Out loom-frame. (Not shown.) Ahand-bar 5 is ting Mechanism for Pile-Fabric Looms, of secured in this instance to the plate 4 by screws which the following is a specification. 5. .Along the inner edge of the plate 4 is in 55 My invention relates to loop-cutting mechthis instance a recessed or angular grooved IO anism for pile-fabric looms, and more parportion 4.
ticularly to improvements in the mechanism The loop-cutting mechanism embodyingmy' for cutting the loops in that class of carpetimprovements consists of a series of cutters. looms in which the needles or wires over which There is a cutter for each row of loops in the 60 the loops are formed extend in the direction fabric. In this instance I have shown the 5 of the length of the fabric and the loops also cutters or knife-blades as removably supportextendin the direction of the length of the ed in holders 6; but the cutters may be-made fabric, a part. of the holders 6 and not detachable The object of my invention is to improve therefrom, as is customary, if preferred. The 5 upon the construction of the mechanism for cutter or knife-blade holder 6 is preferably cutting the loops as now ordinarily made in made of sheet metal cut into the desired the class of looms referred to; and my invenshape and bent along its middle portion and tion consists in certain novel features of conthe two parts brought together and shaped structionof myimprovements, as will be hereto' form a rounded or needle-shaped end 6 7 inafter fully described. y to extend into the loops 2 of the fabric 2.
5 Referring to the drawings, Figure 1 is a The other enlarged end of the cutter-holder plan view of a loop-cutting mechanism em- 6has a straight edge 6" thereon to bear against bodying my improvements and showing a secthe edge of the plate t and also in this instance tion of looped fabric with some of the loops a lug or projection 6 thereon to extend over 75 cut. Fig. 2 corresponds to Fig. 1, but shows and rest upon the grooved or recessed portion 3 a modified construction of the loop-cutting 4 on the plate 4. (See Fig. The knifemechanism. Fig. 3 is a section on line 3 3, blade holder 6 intermediate the rounded .end Fig. 1, looking in the direction of arrow at, 6 and the enlarged end has in this instance same figure.

In the accompanyingdrawings, 1 isaportion are free to move sidewise to adapt their poof a supporting-plate attached 'to the loomsition to therow of loops on the fabric into frame (not shown) and upon which the woven which the rounded or needle-shaped end 6 of fabric 2 is supported and over which it passes the cutter-holder extends.
and by resting on the plate 1 without being attached to said plate.
In Fig. 2 is shown a modifiedeonstruction of myloop-cutting mechanism. In said figure is shown a spiral spring on the plate 1, which extends over the ends of the cutter or knifeblade holder 6. The spirals of the spring 8 are so arranged that the enlarged end of each holder 6 extends bet-ween two adjoining partial spiral convolutions of the spring.
The spring 8 may be employed as a supplemental attachment to yieldingly hold the enlarged ends of the cutters or knife holders 6 in their proper upright position.
In Fig. 8, in addition to the parts above described, are shown two longitudinal pile wires or blades 8 and 9, over which the loops 2 on the fabric are formed. Said pile-wires 8 and 9 in this instance extend in two different planes at their attached ends and are secured to the upright blades 10, attached to the guide-strips supported in this instance on the transverse bar 12 and passing loosely at their lower ends through transverse bar 18. The lay sword 14 carries thelay 15,havingthe reed 16 thereon. The Warp-threads 17 pass through the reed to form the woven fabric and the loops thereon in the ordinary Way. The position of the longitudinal pile-wires relative to the other parts of the mechanism shown and described is clearly shown in Fig. 8.
It will be understood that the details of construction' of my improvements may be varied, if desired.
Instead of having the blades 7 made separate and removable from the holder 6, as shown in the drawings, a knife or cutting edge maybe formed directly on the inclined portion of the holder 6, in which case the holder will act as a cutter or blade, and the shape thereof Will correspond with the shape shown in Fig. 4.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
'1. In loop-cutting mechanism for pile fabrics, the combination with a stationary transverse plate, bar, or red, of a series of cutter or knifeblade holders, having one end reduced to extend into the loops on the fabric, and the other end bearing against said transverse plate and cutter or knife-blades supported by said holders, said holders being free to bodily move laterally or sidewise.
2. In a loop-cutting mechanism for pile fabrics, the combination with a stationary transverse plate, bar or red, of a series of cutter or knife-blade holders, having one end adapted to extend into the loops on the fabric, and the other end bearing against said transverse plate, and cutter or knife-blades, supported by said holders, said holders being free to bodily move laterally or sidewise.
3. In a loop-cutting mechanism for pile fabrics, the combination with a transverse stationary plate, bar, or rod, of a series of cutter or knife-blade holders havingone end reduced to extend into the loops on the fabric, and the other end bearing against said transverse plate, bar, or rod, and cutters or blades detaehably supported on said holders, said holders and cutters or blades carried thereby being free to bodily move laterally or sidewise, substantially as shown and described.
4. In apilc-fabric loom,the combination with longitudinal pile-wires extending in the direction of the length of the warp-threads, and over which the loops are formed, of knifeblade holders extending in the direction of the length of the warp-threads, with one end extending into the loops on the fabric, and the other end bearing against a stationary transverse plate, bar, or red, and said transverse plate, bar. or rod, said knife-blade holders being free to move bodily sidewise or laterally, substantially as shown and described.
5. In a pile-fabric loom, the combination with longitudinal pile wires or blades extending in the direction of the length of the warp-threads, and over which the loops on the fabric are formed, of cutters or blades extending in the direction of the length of the warp-threads, and adapted to cut the loops on the fabric, said cutters or blades being free to bodily move laterally or sidewise and a stationary transverse plate, bar, or rod, against which said cutters or blades bear, substantially as shown and described.
6. In a loop-cutting mechanism for pile fabrics, the combination of a supporting-frame and a series of cutters or blades adapted to engage and cut the pile-loops of the fabricto be treated, said cutters or blades being free to bodily move laterally or sidewise of said frame to adapt their position to the rows of loops on the fabric.
7. In a loop-cutting mechanism for pile fabrics,the combination with a supporting-frame, and a spiral spring, of a series of cutters or bladesadapted to engage and cut the pileloops of the fabric to be treated, each cutter or blade extending between two adjoining spiral convolutions of the spring, and yieldingly held to bodily movelaterally orsidewise of said frame, to adapt their position to the rows of loops on the fabric, substantially as shown and described.
