0. GOODLEY LACE FABRIC Filed Nov. 26, 1934 INVENTOR 'uuliuili ll'zi-l ATTORNEY Patented Dec. 17, 1935 PATENT OFFICE LACE FABRIC Charles Gocdley, Kingston, N. Y., assignor to United States Lace Curtain Mills, Kingston, N. Y., a corporation of New York Application November 26, 1934, Serial No. 754,777

3 Claims.

The object of the present invention is to provide a new lace fabric produced on a Nottingham curtain machine and usually comprising a warp, spool threads and bobbin tie threads, either single or double, and the novel ground of the fabric being produced by dropped ties of the single or double spool threads which are thrown in either direction between two pillars or pillared singly or both together in such manner as to form a long or short cross, a diamond, a hexagon, or other fancy type of net which can be put in at will on any section of the fabric.

. It has long been known in the art to employ spool threads for clothing effects by moving spool threads from one pillar to the leftand back again to the right one or more gaits and also to manipulate the spool threads to produce open work effects by pillaring the spool threads at desired points. My invention is differentiated by the primary fact that in my lace fabric, spool threads not only pillar in the ordinary way, but pillar along with both the spool and warp thread on the immediate left when desired, and float and tie in to form a fancy ground with or without beam threads.

The invention will be described with reference to the accompanying drawing, in which:-

Fig. 1 diagrammatically illustrates the arrangement of warp and spool threads in a simple form of the lace fabric.

Fig. 2 is a diagrammatic view showing the arrangement of warp and spool threads in a more complex pattern than that illustrated in the preceding figure. 1 r

Fig; 3 is a front elevation of structural members employed in the manufacture of lace fabric showing interceptors, interceptor guides and bobbins with their carriages. r

Fig. 4 is a sectional side elevation of the elements shown in Fig. 3, the bobbin carriage being in front motion and an interceptor shown withdrawn.

Fig. 5 is a schematic view showing threads in the formation of a diamond net.

Referring to Figs. 3 and 4, it will be noted that in the manufacture of my new lace fabric, a Nottingham lace machine is employed, the means embodying a spool bar I, a warp bar 2 and, if desired, a beam bar 3. A jacquard controlled interceptor 4 is provided for each spool thread a. At 5 I have shown one of the bobbins in its carriage 6, the bobbin thread being shown at c.

In the drawing, the warp thread is indicated at b.

In the operation of the machine to form my lace fabric, the warp bar moves one gait to the left on the first or back motion and one gait to the right on the second or front motion. The spool bar I. executes the following movement:

On the back motion it moves-one full gait to the left, pauses while the interceptors make their selection, and then moves another gait to the left. On the front motion the spool bar moves one gait to the right, pauses for selection by the interceptors, then moves an additional gait to the right. The selection by the interceptors, which are in action each motion, is effected by means of either two jacquards or one jacquard operating at double speed.

The formation of ordinary work in the lace, as, for example, for the clothing effect, Fig. 2, may be efiected by employing the interceptors in a known and usual manner, i. e., by holding the interceptors out of action on both motions. In. the

formation of open work, ordinary pillaringof the spool threads is secured by moving the interceptors into the threads every alternate motion, that is tosay, when the carriages are in the back comb bar 8. The thick or double pillaring shown at lllx, Fig. 2, is secured by moving interceptor A into the threads. On No. 1 motion when carriages are at back, withdrawing it on No. 2 motion when carriages are at front. Interceptor B works in an opposite manner, i. e., it is withdrawn when on No. 1 motion and released on No. 2 motion.

-It is the floating of spool threads preliminary to Motion number Interceptor A Interceptor B Withdrawn.

Released.

Released do Withdrawn. Reledased Released.

The above movements of the interceptors are repeated throughout the machine where an equally sided diamond net is desired. The number of motions on which the interceptors are released simultaneously as in 3, 4, 5, 6, 7, 8, 11, 12, 13, 14, 15, 16 determines the length of the diamond from N to 0. It will therefore be noted that each spool thread between the points N and P Fig. 5, has been floated, i. e., held against pillaring or'tie, by the action of the interceptors. 5 In other words, between the points N and P, Fig. 5, the interceptors have held the spool threads from being tied during the path of action of the bobbins; and at the point P spool thread 'a has been tied to its own pillar, and spool thread a 10 has been tied to the pillar at the left of its own pillar. Between the points P and both spool threads have been floated until they reach the point of tie at O on the pillar normally that for spool thread a 15 In Fig. 1, I have shown successive vertical rows of diamond figures 9 formed exactly in the manner specified with respect to the diamond of Fig. 5, but the number of motions of the interceptors have been reduced in accordance with the re- 30 duced length of the diamond between N and 0 (refer to Fig. The intermediate rows of hexagon Figures are formed by pillaring the spool threads a and a from the point 0 a distance equivalent to the desired length of the vertical bar forming a part of the hexagon in each case. This double pillaring is effected, as explained above.

Referring to the cross formation at Him, (see Fig. 2), this is effected by pillaring the spool threads a, a from the final tie below the cloth ing 1 for a length equivalent to the desired upper part of the cross, thence throwing the said spool threads in opposite directions between two pillars a desired number of times to form the transa verse bar of the cross figure, and thence ,pillaring the two threads to form the lower longitudinal part of the cross. When the auxiliary or beam bar 3 .is employed, it may be actuated by a suitable cam to throw beam threads according .to

q; usual practice for strengthening the fabric, as,

for example, by producing a square ground. This will be understood by those skilled in the art and does not require illustration in the drawing.

Having described my invention, what I claim and desire to secure by Letters Patent, is as follows: 5

1. A lace fabric made upon a curtain lace machine with a single jaquard and two bars, one spool and one warp bar, the fabric comprising a series of pillars, each formed of a warp thread,

a spool thread employed as a filling, and a bobbin 10 thread, the spool threads being traversed and tied by bobbin threads to the warp, the same spool thread also being pillared, singly and doubly, at spaced points of the fabric and the same spool thread also being floated to form dropped ties at predetermined points.

2. A lace fabric made upon a curtain lace machine with a single jaquard and two bars, one spool and. one warp bar, the fabric comprising a series of pillars, each formed of a warp thread, a '20 spool thread employed as a filling, and a bobbin thread, the spool thread being traversed to form clothing at areas of the fabric, the same spool thread being pillared in the usual manner, and the spool thread being doubly pillared, and the spool thread being floated from points of tie to lower predetermined points on adjacent pillars.

3. A lace fabric made upon a curtain lace machine with a single jaquard and two bars, one spool and one warp bar, the fabric comprising a series of pillars, each formed of a warp thread,

a spool thread employed as a filling, and a bobbin thread, the spool thread being traversed to form clothing at areas of the fabric, the spool thread being pillared in the usual manner and the spool thread being doubly pillared, the spool thread at each doublepillar being tied thereto by the bobbin thread and carried to the warp thread on the immediate left of its normal warp thread.
