OF PHILADELPHIA, PENNSYLVANIA,

TRADING AS GEORGE S. COX AND BROTHER.

HAlRCLOTH-LOOM.

SPECIFICATION forming part of Letters Patent No. 795,255, dated July 18, 1905.

Original application filed December 31, 1903,

To all whom it may concern.-

Be it known that 1, GEORGE S. Cox, a citizen 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 drawing, which forms a part of this specification.

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

This application is a division of an application filed by me December 31, 1903, Serial No. 187,266.

The object of the invention set forth in that application was to produce a loom adapted to the manufacture of that variety of cloth shown, described, and claimed in Letters Patent to WValter S. Cox, No. 726,648, dated April 28, 1903, in which sections of linen or other flexible weft alternate with sections of horsehair or other stiff material and also adapted to the manufacture of that variety of cloth shown, described, and claimed in Letters Patent issued to me September 13, 1904:, No. 769,790, in which a pick of hair and a pick of yarn are contained in each shed of warp. In the said application I have shown and described a loom adapted to the manufacture of both of these fabrics and have laid claim broadly to means employed in common in the manufacture of both of said fabrics. I have also laid claim specifically to the mechanism for manufacturing the first-named variety of cloth. I have not claimed specifically the mechanism for manufacturing the secondnamed variety of cloth. The present application sets forth only the mechanism required. to produce the second-named variety of cloth, in which, as before stated, a pick of hair and a pick of yarn are combined in each shed of warp, and the claims are restricted to such mechanism.

In the drawing the figure represents a side elevation of the loom.

a is the frame of the loom, having suitable Serial No. 187,266. Divided and this application filed June 3, 1905. Serial No. 263,529.

bearings for the studs of the lay b, for the spindles of the warp-beams 0 and take-up roller (Z, for the shaft of ratchet-wheel and for the crank-shaft f.

g is a spur-gear on the shaft of ratchetwheel 9.

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

a 1' 75 Z are the chain of gears connecting the gears g and h, whereby the take-up roller is operated.

T o avoid confusion in the drawing, the usual Well-known mechanism for operating the lay is not shown.

t is the usual trough or receptacle containing the separate strands of horsehair.

1' is the yarn-carrier for the linen, cotton, or other yarn which it is designed to use in connection with the hair, as before stated, to form the weft of the compound cloth.

a 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 the trough by the selector 8 and pull it across the loom. This nipper acts in my machine to grasp simultaneously a pick of hair and a pick of yarn and pull them across the loom.

11 is a slide by which the hair-trough t is supported. The slide 11 has alimited movement to and fro on the slide 10, (which for the purpose of this invention may be stationary.

12 is a guide in the slide 10, through which extends the rod 13, to which is attached the thread-carrier r. The trough t is directly under the selector, so that at each reciprocation of the selector a pick of hair will be selected from the trough and presented to the nipper at the beginning of its throw. The outfeedeye of the yarn-carrier extends opposite the jaw of the selector, so that the yarn extending therethrough will be in position to be grasped by the nipper at the same time that the latter grasps the strand of hair picked by the selector. The trough is given the usual reciprocating motion by means of a connecting-rod m, pivoted at one end on the slide 11 and at the other end on the gear 0,

which is driven by the gear 7), the shafts of both gears turning in bearings in the slide 10. Fixed to the shaft of gear 3) is a ratchet-wheel Q, which is turned by a pawl /1., pivoted on the upper end of the lever 41. The lever w is pivoted between its ends on the shaft of gear 7), the lower end of lever '21 being connected by the link w with the lay Z). The lay thus im parts to the lever '21 a constantly-reciprocating motion, thus causing the pawl w. to turn the ratchet q tooth by tooth. This movement of the ratchetavheel imparts through gears 72 and 0 and connecting-rod m an alternate step-by-step advancing motion and a step-by-step receding motion to slide 11 and trough i thus bringing all sections of the trough immediately under the selector.

1 Will now describe the mechanism for actuating the ratchet (3, which, as above described, actuates the take-up roll.

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 rod 57 with the bracket 58.

55 is a pawl pivoted to the lever 56. This pawl is the operative pawl for the ratchet a, turning the latter at each forward stroke of the lay. During the operation of the pawl 55 the pawl 60, which is pivoted to the frame, acts as a holding-pawl;

It is necessary to cut off the yarn at about the time (preferably just before) the completion of the throw of a pick by the nipper n. To effect this, I provide a cutteror shears, one blade 61 of which is secured to the loomframe, While the other blade 62 is pivoted to blade 61 and connected, by means of a link 63, with the end of the bell-crank lever 64:. The other end of the bell-crank is connected by a link 65 with the lower end of a lever 66, pivoted between its ends to the frame, the upper end of the lever carrying the roller 67.

68 is a cam on the crank-shaft, having an abrupt descent from its highest to its lowest point, so that when the roller 67 overrides its highest point the spring 69, acting upon the lower end of the lever 66, is free to draw that end of the lever back rapidly, thus, through link 65, bell-crank 64:, and link 63, drawing down the cutting end of the blade 62 of the shears and severing the yarn. 1mmediately thereafter the cam 68 again acts upon the roller 67 to move the lever 66 to its illustrated position, thus again opening the blades of the shears.

Pivoted to the top of rod 13, to which the yarn-carrier is secured, is one end of a connecting-rod 70, the other endof which is connected to a lever 70, which is pivoted to a bracket 71.

73 is a bracket secured to lever 70 and, having the roller 7st, which contacts with the cam 75, secured to the gear 76, which is the usual gear for operating the selector a, as will be hereinafter described. The gear 76 is driven by gear 77, which is driven by means of connections from the crank-shaft, not shown, but well understood by those familiar with haircloth-looms. As cam '75 rotates it actuates lever 70 and rod 70, the rod 13, and yarn carrier 1*. The shape of the cam is such that it moves the yarn-carrier down just after the nipper starts to pull the yarn across the loom and holds it down until after the shears have sev ered the yarn, immediately thereafter imparting to the yarn-carrier a quick up-anddown movement and then during the return travel of the nip per moving the yarn-carrier u p to its in i.- tial position. The spring-70, secured to lever 70, accelerates these downward movements. The purpose of this peculiar movement is fully set forth in the said application and is of special importance in connection with the manufacture of that variety of cloth in which sections of linen or other flexible weft alternate with sections of horsehair or similar stiff material. It is desirable, however, in the manufacture of a cloth containing a pick of hair and apick of yarn in each shed of warp to retain this mechanism, as the final up-anddown movement of the yarn-carrier prevents the free end of the yarn from being entangled with the selector and insures it being thrown in the approximately vertical position necessary to enable the nipper to grasp it.

The selector 8 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 secured to and driven by the gear 76 before mentioned, 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.

9st is a lever pivoted between its ends to the bracket 93, one end of the lever engaging the part 91 and the other end the cam 95. hen the upper end of lever 94L is brought opposite the low point of the cam 95, the spring 96 at once moves the lever 94: 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 94: rides up onto the high point of the cam 95, the lever 91 is retracted from the part 91 of the selector, permitting it to drop to close the jaws.

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

1. In a loom, in combination, a source of hair-supply, a source of yarn-supply, a pickinserting device adapted to grasp a pick of weft and pull it across the loom, and means enabling the pick-inserting device to grasp simultaneously a pick of hair and an end of yarn and pull them across the loom, substantially as described.

2. In a loom, in combination, a hair-trough, a

selector adapted to successively select strands of hair from said trough, a source of yarnsupply, and mechanism adapted to cause said yarn and said strands of hair to be inserted together in successive sheds of Warp, substantially as described.

3. In aloom, in combination, ahairtrough,a selector adapted to pick a strand of hair from said trough, a yarn carrier, and a nipper adapted to grasp simultaneously the hair picked by the selector and the yarn carried by the yarn-carrier, and pull them across the loom, substantially as described.

Q. In aloom,in combination, ahair-trough, a vertically-reciprocated selector, a yarn-car- &

rier having an outfeed-eye alongside of the selector, and a nipper adapted to grasp simultaneously the pick of hair selected from the trough by the selector and the end of the yarn projecting from the yarn-carrier and pull them across the loom, substantially as described.

In testimony of Which invention I have hereunto set my hand, at Philadelphia, on this 30th day of May, 1905.

GEORGE S. COX.
