WIRE-FENCE, FABRIC.

SPECIFICATION forming part of Letters Patent N0. 769,223, dated September 6, 1904. Application filed N ve bfi 15, 1902. Renewed November 9, 1903. Serial No. 180,396. (No model.)

To all whom it may concern,-

Be it known that I, THOMAS LITWILLER, a citizen of the United States, residing at Tre-= mont, in the county of Tazewell and State of Illinois, have invented certain new and useful Improvements in Wire-Fence Fabrics; and I do hereby declare that the following is a full, clear, and exact description ofthe invention, which which it appertains to make and use the same. This invention has reference to wire fenclng. The object ofthe invention is to providea wire fence formed of body-wires and selvagewires, and connected or intertwisted with the. body and selvage wires are wire stays that bear diagonally to the body of the fence and are intertwisted with the selvage and body wires ,where they intersect alternately -inopposite directions.

. The invention has for its further object a fence which is durable and cheap at first cost and that may be and is produced by a machine wherein the fabric is continuously drawn out and reeled without interruption during the feeding of and intertwisting the stay-wires with the longitudinal wires forming the body of the fabric.

'Figure 1, drawn to a small scale, shows a strip of fencing embodying my improvements as it appears when placed in the field. Fig.

2, drawn to a larger scale, shows more clearly the detail construction of the fence and is a section from Fig. 1 bounded by the dotted line shown in such figure.

The fence comprises what will be hereinafter known as the selvage-wires 1 and the body-wires 2, arranged at suitable inter- Vals apart from each other intermediate the selvage-wires to present a uniform or graduated mesh, as may be desired, and 3 indicates stays, preferably of wire, spaced at suitable intervals apart and'adapted, as shown, to be intertwisted with the selvage and body wires, which together comprise my improved fencmg.

Attention is called to the selvage-wires 1,

will enable others skilled in the art to end wires.

which I have shown as twisted cable-strands; but it is to be understood that the selvagewires may comprise each a single wire of suitable strength in proportion to the heft of the body-wires common in all fences.

In making the fence,-which iscontinu-ously fed from the machine, producing a finished productwithout interruption, which ordinarily occurs at intervals after placing each stay, the bobbins which; carry the wire comprising the stays are fed across the selvage and body wires obliquely or diagonally to the longitudinal bearing of these wires, and hence shows the stays bearing in diagonal lines, presenting a rectangular meshhaving horizontal top and bottom wires and sloping or slanting By this mode a seriesof carriages are provid ed. carrying bobbins, each containing a spool of wire which forms the stay, and

the carriages will follow each other at intervals apart, moving across the body and selvage wires, and successively cause their stay-wires to be intertwisted with coinciding body and selvage wires alternately in opposite d irections for example, follow the first complete staywire 3 to the left of Fig. 1, leading from the lower selvage-wire 7 It is intertwisted with the selvage 1 at a a portion of its length. It is then led diagonally to the adjacent bodywire 2 and intertwisted therewith, as at b, in

.a directionopposite to thatshown at a; The

wire 3 is then led diagonally to the next adjacent body wire 2 and continued to be so led until it coincides with the upper selvage-wire 1, with which it is intertwisted or wrapped around, when the wire is out shortly after the spool leaves the selvage, leaving the free end of the stay directed longitudinally, as at 4. The appearance of the stay-wires at the bottom ofthe fence will be the same as at the top or upper end, and the stay just referred to as itis brought coincident with each succeeding, body-wire is intertwisted therewith inopposite directions,,-as at a and br,that is,

the stay-wires are intertwistedwiththe bodywires in opposite directions byleading the RBI-sense) the finished-product, as shown in Fig. 1,

said stay-wires first over the body-wires and then under the same, as seen in the figures, which is accomplished by rotating the twisters of the carriages first in one direction and then in an opposite direction. By following each stay from left to right the intertwists appear in opposite directions, but follow a series of twists in a diagonal line from right to left, crossing a series of stays and body-wires, and the twists all appear similar.

Attention is now called to the body-wires which are slightly drawn out of horizontal line where the twist is made with the staywires occasioned by the peculiar manner in which the stays are carried. The twists slant in one direction, while that portion of the body-wires intermediate the twists, as at a, slant in an opposite direction. Attention is also called to the variations in the slant of the stays or that portion of each stay intermediate or connecting the body and selvage wires. The slant is greater where adjacent longitudinal wires are closest and less where they are farthest apart. However, the exact incline or diagonal position of the stays may be modified, as also the arrangement of the bodywires, and it may be convenientinstead of twisting both the body and stay wires where they are coincident to twist only the stay around the body-wires,or vice versa, or twist the stay andpartially twist the body-wire, all of which, it is believed, will come within the scope of the invention. The alternate stays, beginning with the second, have their twists with the selvage-wire just opposite to those of the first stay. This is occasioned by the fact that these stays are not introduced into the fence until after the preceding stay-wires and their carriages are coincident with the lowermost body-wire. A series of carriages .are employed and ushered into use in this manner until the carriage carrying the first-mentioned stay has passed the upper selvage-wire and caused to be twisted therewith its stay, when it assumes its position with the lowermost selvage and each step of the process carried out as hereinabove set forth. In this way adjacent stay-wires where theyare intertwisted with a body or selvage wire will be in opposite directions, not only vertically, but longitudinally. (See Fig. 2.)

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. A wire-fence fabric, composed of bodywires and selvage-strands, of stay-wires extending obliquely across the body-wires from selvage-strand to selvage-strand and at each succeeding point of intersection with the selvage-strands and body-wires twisted therewith alternately over and under, substantially as described.

2. In a wire-fence fabric, the combination of a series of body-wires, and stay-wires, extending obliquely across the body-wires from selvage to selvage the twist of adjacent stays with corresponding body-wires being alternately over and under and having the twists measured along the body-wires in the same direction, substantially as described.

3. In a wire-fence fabric, the combination of a series of body-wires and selvage-strands, stay-wires extending obliquely across the series of body-wires and twisted with adjacent body-wires alternately over and under, and adjacent stays twisted with corresponding body-wires alternately over and under and having the twists measured along the bodywires in the same direction, substantially as described.

4. In a wire-fence fabric, the combination of a series of body-wires and selvage-stramls, staywires extending obliquely across the body-wires from selvage to selvage and twisted with adjacent body and selvage wires, alternately over and under and having the twists of the stays and body-wires measured along the body-wires in the same direction, and short longitudinally-presented extensions of each stay where they are twisted with the selvage-strands, substantially as described.

5.
