WIRE-FENCE LOOM.

Specification of Letters Patent.

Patented Dec. 14, 1909.

Application filed January 30, 1909. Serial No. 475,224.

To all whom it may concern:

Be it known that I, VERNON Hoxrn, a citizen of the United States, and a resident of Adrian, in the county of Lenawee and State of Michigan, have invented a certain new and useful Tire-Fence Loom; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to looms of the class particularly adapted for the weaving of wire fencing in which the stay wires are held between companion sets of warp wires which are alternately crossed or spread in reverse directions as successive stay wires are fed therebetween, whereby to securely bind the stay wires in spaced relation thereto as is hereinafter more fully described.

The object of my invention is the provision of an improved machine of this class, which is simple and easy of operation, and which is provided with simple and highly elficient means for alternately spreading the companion sets of warp wires in reverse directions. as the stay members are fed therebetween, whereby to enhance the practicability and commercial value of the machine.

The operation, construction and arrangement of the parts of the invention are fully described in the following specification, and a preferred embodiment thereof is illus trated in the accompanying drawings, in which,

Figure 1 is a plan of the machine with portions broken away. Fig. 2 is a side elevation thereof. Figs. 3 and 4 are side elevations of a set of warp wire spreading arms in different positions of their rocking move ments. Figs. 5 and 6 are front and end views, respectively, of one of said arms, and Fig. 7 shows details of the clutch mechanism.

Referring to the drawings, 1 designates the weaving table of the loom from the forward end of which extend the side sills 2, 2, in approximately the plane of the table top.

Mounted in suitable bearings 3 at the rear end of the table, transversely thereof is a rock shaft 4, which carries two sets of warp wire spreading arms 5 and an arm 6, which latter connects with suitable actuating mechanism hereinafter described through the medium of a rod 7. The sets of arms 5 er:- tend from the shaft 4 at approximately right angles to each other, or preferably so, as shown, and have their outer ends laterally angled or curved in planes transverse to the shaft 4 and in converging relation, as shown at 8. The portions 8 are provided with eyes 9 which are also disposed in planes transverse to the shaft 4 and through which the warp wires of the fabric being woven are threaded. The eyes 9 vertically broaden from their inner ends outwardly with their opposing upper and lower walls at substantially right angles to each other if the arms are intended to have a quarter rocking movement as in the present case, or so relatively disposed that a wire threaded therethrough will make contact with the upper or outer wall of the eye when the arm is in horizontal position, and with the lower or inner wall of the eye when the arm is in vertical position, as shown. To enable the wires which are threaded through the eyes of the separate sets of arms to pass each other as they are moved in opposite directions by a rocking of the shaft 4 first in one direction and then in the other, the arms of one set preferably alternate with the arms of the other set, as shown in Fig. 1.

The rod 7, which communicates movement to the shaft 4 has its inner end attached to a crank-arm 10 carried by a shaft 11, which is mounted in pedestal bearings 12 beneath the table 1, and carries a spur-gear 13 in mesh with a smaller gear 14 on the shaft 15. The shaft 15 is mounted in pedestal bearings 16 in parallelism with the shaft 11 and carries a loose spur-gear 17 in mesh with a smaller spur-gear 18 on the drive-shaft 19, which is mounted in suitable bearings 20 and carries a belt pulley 21. Feathered to the shaft 15 at one side of the gear 17 is a clutch of the single revolution type, which is adapted to be moved into clutch engagement with the hub of said gear by a depression of the foot treadle 28, which is connected by a trip cord or wire 24 to the trip member of the clutch. lVhile any suitable form of single revolution clutch may be used, a simple form is shown in Fig. 7, in which 22 designates the clutch collar, which is feathered to the shaft 15 and is normally influenced to move into clutch engagement with the hub of the gear 17 by the weighted bell-crank lever 22; 22 being the bolt or trip member which works within a cam-groove 22 in the collar, and 22 a bellcrank lever connecting the trip-member 22 with the trip-cord 2a. The gears 13 and 14: are proportioned two to one so that a half revolution is imparted to the crank-arm 10 at each revolution of the shaft, 15, and the connection between the crank arm and rockshaft 4L is such that a quarter revolution is imparted to it at each half revolution of said crank arm. As the shaft 11 is successively actuated the shaft 4: is rocked first in one direction and then another, to alternately lower and raise the arms 5 to effect a successive spreading of the wires in opposite directions.

A reel or drum 25 on which the fabric is wound as it is woven is mounted transversely of the forward end of the machine and has its shaft ends journaled in suitable bearings 26 which are secured to the sills 2 near the forward ends thereof. Mounted on the shaft with the drum 25 and at one end thereof is a spur-gear 27 which meshes with a companion gear 27 carried by shaft 28. This shaft 28 is mounted in bearings 29 secured to the sills 2, and is driven from a shaft 30 through the medium of the sprocket wheels 31 and 32 on said shafts and the sprocket chain 33, which is shown as working under an idler-sprocket 34L, the shaft of which is mounted in a suitable bearing ,35. The shaft 30 carries a ratchet-wheel 36 with which a dog 37 coacts, said dog being carried by an arm 38, which is loosely mounted on the shaft 30 at the side of the ratchet-wheel and is connected by a rod 39 to a crank-arm 40 on the shaft 15, thus causing a predetermined movement to be communicated to the shaft 30 at each revolution of the crank arm 40. The movement of the drum is so proportioned relative to that of the shaft 15 as to move the fabric being woven a distance equal to the space between the stays at each revolution of the shaft 15, which movements of the fabric take place simultaneously with the spreading of the arms 5. A free back turning of the drum 25 is prevented by the provision of a friction-clutch on the shaft 28, which comprises a disk 41 carried by such shaft and an embracing friction band 42, which is prevented from turning by being attached to one of the sills 2.

as designates an idler roll which is carried by the sills 2 immediately in advance of the table 1 and is intended to hold the fabric to the surface of the table.

In practice the warp wires a are preferably crimped (though not so shown) before being fed to the loom, and the woof or stay Wires 1) are fed by hand between the alternately spread warp wires a short distance in advance of the cradle which is formed by the shaft 4 andarms 5. When a woof or stay wire has been fed between the diverging sets of warp wires and forced home by hand or in any other suitable manner the operator depresses the treadle 23 with his foot thus throwing the clutch 22 in engagement with the hub of the gear 17 and causing a single revolution to be imparted to the shaft 1.5 from the drive shaft 19. As the shaft 15 revolves, a half revolution is communicated to the shaft 11 and crank arm 10 and a consequent quarter revolution is imparted to the rock shaft l which effects a rocking of the arms 5 to cross the alternate warp wires (1. at the rear of the woof wire to secure it in position in the fabric. During the reversing of the positions of the sets of warp wires the fabric is drawn forward a distance equal to the space between the woof wires due to a partial revolution being communicated to the drum 25 from the crank-arm 40 and the shaft 15 through the medium of the rod 39, ratchet wheel and dog 36 and 57, shaft 30, sprocket-wheels 31 and 32, chain 33, shaft 28 and meshing gears 27 and 27. The operator now feeds another woof wire between the spread warp wires, depresses the treadle 23, and the reversing of the positions of the sets of warp wires to the rear of the woof wire and the feeding of the fabric forward is repeated as before.

It is apparent that the arms 5 form a simple and eflicient cradle for crossing the alter nate warp wires at the rear of a warp wire and spreading them to facilitate the insertion of another woof wire.

I wish it to be understood that my invention is not limited to any specific arrangement or construction of the parts except in so far as such limitations are specified in the claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is 2- 1. In a loom, a rocking warp wire spreading cradle having two relatively angled sets of arms, each of which arms has its outer end angled in the direction of the other set and provided with a warp wire receiving eye the inner and outer walls of which diverge from each other in the direction of movement of the wires therethrough, and mechanism for rocking the cradle to reverse the positions of the sets of wires threaded through the cradle arms.

2. In a loom, a wire spreading cradle, a continuously revolving member, a shaft, a single revolution clutch movable to impart a single revolution to said shaft from said member, a second shaft, means for communicating a partial revolution thereto from a revolution of said first shaft, means connecting said second shaft and cradle for rocking the cradle when the second shaft and the cradle is actuated, a fabric winding reel, and

means for imparting a predetermined movement to the reel at each revolution of said first shaft.

3. In a loom, the combination of a rocking Warp Wire spreading cradle, a drum on which the fabric Winds, a continuously driven shaft, a second shaft, means operative to communicate a single revolution to the second shaft from said continuously driven shaft, a crank carried by said second shaft, a ratchet mechanism intermittently actuated by a revolution of said crank, means actuated by said ratchet mechanism for imparting intermittent movements to said drum, a third shaft, means for c0mmunicating a partial revolution thereto from a revolution of said second shaft, a crank carried by said third shaft, a crank carried by said cradle, and a pitman connecting said two cranks for imparting a rocking movement to said cradle when said third shaft has movement imparted thereto.

In testimony whereof I have hereunto signed my name to this specification in the presence of two subscribing Witnesses.

VERNON HOXIE.
