HAIRCLOTH-LOOIVI.

SPECIFICATION forming part of Letters Patent No. 795,252, dated. July 18, 1905.

Application filed July 2'7, 1904-.- Serial No. 218,322.

To all whmn it may concern:

Be it known that I, GEORGE S. COX, a citi- Zen of the United States, residing at Fitzwatertown, county of Montgomery, and State of Pennsylvania, have invented a new and useful Improvement in Haircloth-Looms, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to looms, and more particularly to that type of loom adapted to the manufacture of haircloth.

The object of the invention is to produce a loom adapted to the manufacture of cloth in which the weft consists of hair of two ormore different colorsas, for example, a cloth containing alternate picks of black and white hair or a cloth containing alternate series of picks of black and white hair, forming a cloth that is striped on the line of the weft, or a cloth in which designs are produced by using both black and white hair as the weft and manipulating the warp by a jacquard apparatus.

The invention consists of the means hereinafter described and claimed for weaving such multicolored cloth automatically.

In the drawings, Figure 1 is a side elevation of a loom embodying my invention. Fig. 2 is a section on line 2 2 of Fig. 1, showing parts in elevation. Fig. 3 is a detail plan. Fig. 4 is a section on line A 4: of Fig. 3. Fig. 5 is a detail view in side elevation of the mechanism for stopping the rotation of the take-up roller when the selector misses a hair.

The specific machine that I am about to describe is arranged for the weaving of cloth containing wefts of two different kinds or colors, although it will be understood that my invention is not limited to the utilization of any particular number of kinds or colors so long as provision is made for at least two kinds or colors.

(0 is the frame of the loom, having suitable bearings for the studs of the lay b, for the spindles of the warp-beam 0 and take-up roller (Z, for the shaft of ratchet-wheel e, and for the crank-shaft f.

g is a spurgear on the shaft of ratchetwheel 6.

h is a spur-gear on the spindle of the take-up roller d.

2' jlc Z are the chain of gears connecting gears g and h, whereby the take-up roller is operated.

To avoid confusion in the drawings, the usual well-known mechanism for operating the crank-shaft is not shown.

0 t are troughs or receptacles, one adapted to contain weft of one color (say black) and the other adapted to contain weft of a different color, (say white.)

at is the usual nipper, the well-known action of which is to grasp one end of a strand of hair that has been previously selected from a hair-trough by the selector .9 and pull it across the loom. This nipper acts in my machine to pull either a pick of black hair or a pick of white hair across the loom, dependent upon which kind of hair has been previously selected by the selector, and the kind of hair that has been selected by the selector in turn depends upon which of the two troughs is in working relation with the selector. I will therefore first describe the mechanism whereby the two troughs are alternately brought into working relation with the selector.

10 is a slide working in a bracket supported on the loom-frame. This slide carries the slide 11, to which the troughs 1- 23 are secured, one behind the other.

In the drawings, Fig. 1, the trough r is shown directly under the selector .9 and is therefore the trough which is in operative relation with the selector, whose specific construction and operation will be hereinafter described. When, however, the slide 10 is moved back (to the left, Fig. 1) a distance preferably equal to the distance between the median line of the troughs, the trough t is brought beneath the selector and therefore in operative relation therewith, and the trough r is moved out of operative relation with the selector.

- The following means are provided to actuate the slide 1O. 14; and 15 are gears ro tatin g i n bearings in the loom-frame. The gear 15 is connected by a connecting-rod 16 with the slide 10 and engages the gear 14, which I call the index-wheel, and which is of twice the diameter of the gear 15. hen the indexgear 14 is given a quarter-turn, the gear 15 is given a half-turn, drawing the slide 10 into position to move the trough 1' out of operative relation with the selector and the trough 6 into operative relation with the selector. hen

the index-wheel 14 is given another quarterturn, thereby giving the gear 15 another halfturn, the slide is returned to its original position and the trough 1' moved out of operative relation with the selector and the trough 1 into operative relation with the selector.

To give the index-gear 14 a quarter-turn, I provide said gear with four pins 17, arranged ninety degrees apart, said pins being adapted to be engaged in turn by the hooked end of I a lever 18, pivoted between its ends to one end of a lever 19. The other end of lever 19 is pivoted to the loom and between its end is provided with a boss 20. On the crankshaft f is a cam 21, which at each rotation of the crank-shaft engages the boss 20, thus lifting the levers 19 and 18.

Normally the lever 18 reciprocates idly, the hooked end of the lever not being in position to engage a pin. The lever is turned on its pivot to bring it into operative position only when it is desired to actuate the slide to v and change the weft. The lever is so turned on its pivot by lifting the flexible connection 24, which is attached to the upper end of the hooked lever. The other end of the flexible connection 24 extends over a roller 25 and is secured to the end of a lever 240, pivoted on the frame. The lever 240 is also connected by a wire 260 with one end of a draw-bar 26.

262 is a spring, one end of which is secured to the lever 240, while the other end is secured to the frame. This spring normally holds the lever 240 and draw-bar 26 in their normally inoperative positions. The draw-bar 26 is made in two sections, hinged together at 261. The other end 26 of the draw-bar 26 is notched and adapted to be engaged by the constantly-reciprocating knife 27 of the shedding motion. The knife 27 is attached to the ends of connecting-rods 28, which are pivoted to double-ended levers 29, secured to the shaft 50. 30 is a rod connected at one end to an arm 290 on one of the double-ended levers 29 and at the other end to one end of a lever 31, provided with a roller 32, engaging. the eamway of the cam-disk 33 on the cam-shaft, whereby the shaft 50 is oscillated. Normally, however, the knife 27 is ineffective to actuate the draw-bar 26, the notched end of the draw-bar being held above the path of travel of the knife 27 by means of one end of a pivoted lever 34, the other end of lever 34 having a boss 35, which rests on the patternchain 36. When one of the lugs 37 of the y the crank-shaft.

patternchain travels under the boss and lifts it and the corresponding end of the lever 34, the hooked end 26 of the draw-bar 26 drops. Then, as before described, the knife 27 actuates the d raw-bar 26, which through the medium of the connections 24 and 260, moves the constantlyreciprocating hooked lever 18 into position to turn the gears 14 and 15 and shift the slide 10.

Thepattern-chain extendsover the sprocketwheel 38, Which, together with the patterndruin 46 and ratchet-wheel 47, is secured to the shaft 39.

is a pawl-lever pivoted to an arm 450, secured to shaft 50. At each oscillation of the shaft 50 the pawl-lever 45 actuates the ratchet-wheel 47, thereby turning the pattern-drum and the pattern-chain.

I have described the mechanism for actuating and controlling the actuation of the slide 10, and thereby causing the weft to be changed whenever a lug on the pattern chain is brought under the lever 34. ll will now describe the mechanism for actuating the ratchet a, which, as before described, actuates the cloth-beam.

58 is a bracket secured to the lay.

56 is a lever pivoted at its lower end to the frame of the loom and connected at its upper end by a rod 57 with the bracket 54 is a pawl pivoted to the lever 56. At each forward stroke of the lay the pawl 54 turns the ratchet a distance of one tooth. The pawl 60, pivoted to the frame, acts as a holding-pawl.

It sometimes happens that the selector misses a hair, under which conditions it is de sirable to stop the rbtation of the take-up roller in order to prevent the warp feeding forward until after a pick. of hair is thrown. This is effected by lifting the holding-pawl 60 off the ratchet e, as without this pawl the tension of the take-up roller tends to return the ratchet-wheel after it is moved forward by the pawl 54. To raise pawl 60, the following mechanism is provided: Attached to the rear end of pawl 60 is a flexible connection 78, which extends around a roller 79 and thence up to the top of the loom, where it is attached to a lever 80, secured to a shaft 68, turning in bearings on the top of the loomframe. Pivoted to lever 80, near the point of attachment of the flexible connection 78, is a rod 81, to the lower end of which is pivoted a lever 82, having near its lower end a notch 83. Pivoted to the loom-frame is a lever 84, having a boss engaging a cam 86 on As the cam 86 rotates the lever 84 is raised and alug 85 on the free end of the lever is adapted to engage the notch 83 of lever 82, thereby raising lever 82, rod 81, and lever 80, the latter through the flexible connection 78 raising the pawl 60 out of contact with the ratchet wheel 0. Normally,

however, the notched lever 82, just before the Lil lever 84 rises, has been moved into the position shown in the drawings and is not in position to be engaged by the lug 85tl1at is, whenever the selector 8 selects a hair the hair as it is pulled across the loom by the nipper a engages and depresses the finger 87, secured to one arm of the bell-crank 88. The other arm of the bell-crank 88 has a bifurcated end engaging the lower end of the notched lever 82, and when the finger 87 is depressed the bell-crank moves the notched lever 82 into the position shown in dotted lines in Fig, 5 and out of the line of movement of the lug 85; but when the selector misses a hair there is nothing to move the notched lever 82 out of its vertical position, as shown in full lines in Fig. 5, which causes it to be engaged by the lever 84, with the result that the pawl is lifted from the ratchet and remains disengaged until the selector succeeds in picking up a hair. If the selector misses a hair, it is also necessary to stop the operation of the pattern-shaft. This is effected by raising out of action the pawllever 45. The pawl-lever 45 is raised by means of a stud 60, sliding in guides 61, which is raised by the free end of a lever 62, this lever being secured to the shaft 63, to which the lever 80 is also secured,as before described. hen by the operation of the mechanism before described the missing of a pick of hair by the selector dictates the raising of lever 80, the latter through shaft 63, lever 62, and stud 60 raises the pawl-lever 45 out of engagement with the ratchet-wheel 47, the said pawl-lever remaining disengaged until the selector succeeds in picking up a hair.

I have already described how when the lug on the pattern-chain moves under the lever 34 it dictates the shift of the slide carrying the hair-troughs in order to change the weft. It will also be understood that if the lug remained under the lever 34 and held up the lever 34 and then the selector missed a hair the resultant disengagement of the pawl-lever 45 from the ratchet-wheel 47, just described, would cause the pattern-chain to remain stationary, and the lug thereon, continuingto holdup the lever 34, would cause the slide 10 to shift back again. This is obviated by arranging the lugs on the chain out of alinement with the pins 460 on the pattern-drum, so that when the ratchet-wheel 47 is turned a distance of one tooth a line of pins 460 is brought immediately under the corresponding draw-bars, while the lug on the pattern-chain passes under and beyond the lever 34. The lug therefore merely lifts the lever 34 and does not hold it up, the latter function being effected by a weighted bell-crank lever 65, the unweighted arm having a book 66 at one end, which engages a notch 67 on the lever 34 when the latter is lifted by the pattern-chain lug. As before described, when the lever 34 is lifted the drawbar 26 drops and the knife 27 then actuates the draw-bar to operate the chain of mechanism for shifting the slide 10.

68 is a bracket secured to the draw-bar 26, said bracket having a hooked end 680.

650 is a pin on the hooked end of the bellcrank lever 65, said pin being in line of travel of the hooked end of the bracket.

During the last-described operation of the draw -bar just before it has completed its movement the hooked end of the bracket 68 strikes the pin 650, pulling the hooked arm of the bell-crank lever to the right, Fig. 4,

withdrawing the hook 66 from under the notched end of lever 34 and permitting the latter to drop.

The selector .9 is of a well-known construction. It consists of the part 90, vertically movable in guides 92 and carrying the fixed jaw, and the part 91, hinged to the part and carrying the movable jaw.

97 is a shaft to which are secured the cam and the crank-disk 98.

99 is a connecting-rod between the crankdisk 98 and the part 90, whereby the selector is reciprocated vertically.

93 is a lever pivoted between its ends to the bracket 94, one end of the lever engaging the part 91 and the other end the cam 95.

When the upper end of lever 93 is brought opposite the low point of the cam 95, the spring 96 at once moves the lever 93 so as to engage the part 91 of the selector and move it on its hinge to open the jaws. As the upper end of lever 93 rides up onto the high point of the cam 95 the lever 93 is retracted from the part 91 of the selector, permitting it to drop to close the jaws.

In an application filed by me December 31, 1903, Serial No. 187,266, I have shown and described a haircloth-loom embodying many of the features of construction herein set forth, some of which are claimed therein and are therefore not claimed in this application.

Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is

1. In a loom, in combination, a plurality of receptacles for hair, a selector, and mechanism to bring either of said receptacles and said selector into operative relation with each other, substantially as described.

2. In a loom, in combination, a plurality of receptacles for hair, a vertically-reciprocating selector, and mechanism to move either of said receptacles under and into operative relation with the selector, substantially as described.

3. In a loom, in combination, a slide, aplurality of hair-receptacles mounted thereon, a selector, and means to move said slide back and forth a distance sufficient to carry said receptacles successively into operative relation with said selector, substantially as described.
