This invention aims to provide a loom attachment which is so constructed that a leno weave, open mesh laundry bag may be formed by the vertical and lateral movement it of a single harness with respect to a stationary harness.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the 1 invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

The numeral 1 marks a loom frame on which a stationary harness 2 is suspended at 42. On one side of the stationary harness 2 is located a movable harness 3, the comb appearing at 4. In order to provide for an up and down movement of the harness 3, the said harness is carried by flexible straps 5 rove over pulleys 6 on the frame 1 and connected to a counter-weight 7 located on the opposite side of the harness 2 from the harness 3. The lower edge of the counterweight 7 is united by connections 8 with the forward ends of levers 9, and the lower edge of the harness 3 is connected by flexible straps 10 to the forward ends of levers 11, the levers 9 and 11 being fulcrumed at 12, intermediate their ends, on the frame 1. A main shaft 14 is journaled on the frame 1 and is rotated by any suitable means 15, the shaft having eccentrics 16 and 17, the eccentrics 16 cooperating with the rear ends of the levers 11, and the eccentrics 17 cooperating with the rear ends of the levers 9. A bracket 18 forms part of the frame 1, and thereon a countershaft 19 is journaled, the shafts 14 and 19 being connected by beveled gears 20. A wheel 21 is secured to the shaft 19 and has a lateral cam track 22 in which moves a projection 23 on a lever 24 fulcrumed intermediate its ends on the bracket 18, the upper end of the lever 24 moving in a guide 29 on the frame 1. A lever 25 is fulcrumed intermediate its ends on the frame 1, a rigid longitudinally-adjustable link 26 being pivotally connected to the upper end of the lever 25,

and being pivotally and adjustably connected to the upper end of the lever 24. 25 is provided at its lower end with an eye 27, receiving loosely, a loop-shaped connection 28 on one end of the movable harness 3, the construction being such that the harness moves up and down on the lever 25, the lever The lever 10 and 8, the counter-weight 7, and the straps 5. The horizontal or sidewise components in the movement of the harness 3 are derived, by way of the shaft 14, from a train of elements including the beveled gears 20, the counter-shaft 19, the wheel 21, its cam track 22, the projection 23, the lever-24, the link 26, the lever 25, the eye 27, and the connection 28 on the end of the harness 3. I

The stationary harness 2 has bars 30. Between two adjoining bars 30 is located a depending needle 31 having an eye 32, and between one of the aforesaid bars and the next adjoining bar is located an upstanding needle 33 having an eye 34. The movable harness 3 hasbars 35. Between two adjoining bars 35 is located-a depending needle 36 having an eye 37, and between one of the aforesaid bars and the next adjoining bar is located an upstanding needle 38 having an eye 39.

The complete fabric is of the tubular form used in the making of open mesh laundry bag, and for convenience, the bag may be said to consist of a top layer and a bottom layer, a portion of one layer being shown in Figure 10 and comprising warp threads cl and 0 and woof threads 6. The warp threads 03 and c are crossed, as at f, between the woof threads 2. The warp threads of the bottom layer are marked by the letters a and 1), whereas: the letters 0 and d designate'the warp threads of the upper layer. a

The threads (Z and 0 pass between two dents of the comb 4. I The thread cl extends between two adjacent bars 35 of the movable harness 3 and through the eye 34 of the stationary harness 2. The thread 0 extendsthrough the eye 36 of the movable harness 3 and between twoadjacent bars 30 of the stationary harness 2. The threads a and 7 pass between two dents of the comb 4. The thread a extends between two adjacent bars 35 of the movable harness 3 and through the eye 32 of the stationary harness 2. The thread I) extends through'the eye 37 of themovable harness 3 and between two adjacent bars 30 of the stationary harness 2. 2

Referring to Figure 4, the movable harness Y and under the thread (1. In Figure 5, the

movable harness has been moved up and to carried up and to the left.

down and to the left. On the third pick, the

woof thread 6 is carried over the warp threads a, b, and 0, and under the thread d. V r

In Figure 7, the movable harness has been On the fourth pick, the woof thread 6 is carried under the warp threads 03, a, and b, and under the thread 66; At the proper times, considered relatively to the various picks, the threads 0d and 0-?) are crossed on each other at f, to' form the leno-weave. I

Owing to the provision of the mechanism depicted in Figures 1, 2, 3, and13, of the drawings, a single harness, to wit, the harness 3, moving with respect to the fixed harness 2, will effect the completion of a lenowoven tubular bag,the mechanism being simplified greatly.

For convenience, the levers 9, which move the harness 3 up, may be denominated the first levers, the levers 11, which move the harness down, being designated as the sec 7 ond levers, the lever 25 of Figure 1 being the third lever, and the lever 24 being the fourth lever.

WV hat is claimed is 1. In a loom of the class described, a frame,

approximate parallelism to the shaft, the

harness being slidable onrthe third lever, a

link connecting the third and fourth levers, a cam wheel operatively connected with the fourth lever and disposed in approximate parallelism to the shaft, and means for connecting the cam wheel operatively with the shaft.

2. In a two-harness leno-weave loom for making mesh bags, the combination of a 7 frame, a comb mounted upon the frame, two

harnesses having oppositely projecting needles, one harness being stationary on the frame, the other harness being movable'and being located between the comb and the fixed harness, means for mounting the movable harness for up and down movement and for lateral movement with respect to the comb and'the stationary harness, and mechanism for moving the movable harness as aforesaid, to effect a leno-weave.
