PETTIS A. REID, WALTER v. REID, AND JAMES KELLEY, OF RIcIIMoND, INDIANA; SAID WALTER V. REID AND sAID JAMES KELLEY AssIGNORs TO SAID PETTIS A. REID.

To all whom it may concern:

Be it known that we, PETTIS A. REID, WVALTER V. REID, and JAMEs KELLEY, citizens of the United States, residing at Richmond, in the county of lVayne and State of Indiana, have invented certain new and use ful Improvements in Tire-Fabric Machines,'of which the following is a specification.

In our application Serial No. 262,966, filed May 29, 1905, (which became Patent No. 1,160,089, granted Nov. 9, 1915) we show a series of loopers and twisters operating in sequence on account of the progressive loop drawing involved in the operation of that machine.

In this application we show and claim two such series for making two widths of fencing'simultaneously, and on account of the sequential'operation the two series are arranged to draw in surplus material for the loops from opposite ends of the staywire.

In making a single width of fencing, it is preferable for the sake of uniformity of appearance to have all the twisters rotating in the same direction, and-hence .the whole series work sequentially from one marginal twister toward the other marginal twister, so as to have the coils alike across the width of fencing. But when making a double width of fencing (for division into separate widths) the arrangement shown and described herein may be utilized without disadvantage, since the appearance of the coils of each width will be similar. Also, if symmetry and uniformity of appearance may be sacrificed for speed, the same arrangement may be utilized in making a single width ,of fencing.

Referring to the accompanying drawings, which form a part of this specification Figure l is a diagrammatic face view of a double series of loopers and twisters such as disclosed in our saidapplicationSerial N0. 262,966,the respective groups or series working sequentially and both during the same time; 7

Specification of Letters Patent.

Patented June 22, 1920.

Application filed February 15, 1910. Serial No. 543,990.

Fig. 3 is a face view of the four middle loopers and twisters of the double series of Fig. 1, shown beginning action at the center of the stay wire; and

Fig. & is a cross-section of Fig. 2, showing only the principal parts associated with one looper and twister.

Except for the arrangement of loopers and twisters in two series operating in the manner stated, the mechanism illustrated in the drawings is the same as shown and described in our said application Serial Number 262,966, to which reference may therefore be made for a detailed descrip tlon, and in this specification a brief indication of the principal elements will suffice. The individual loopers and twisters of the respective series of the whole comple- Inent or so-called double series are indicated by the consecutive numbers 1, 2, 3, 4, etc., lndicating the sequence of operation of each series, and also indicating the correspondng twisters of the two series which work in pairs since both series are in operation at the same time.

a denotes the twister'spindles; b the twister-heads; c bevel pinions on the spindles; and d the drive-wheels having segmental gears for'engaging said pinions and also having cams for operating levers e which control slip-collars 7 which in turn control the retractable looping pins g in the twister-heads.

. h denotes the feed-rolls for the stay-wire; i the separable guide-tubes which conduct the stay wire across the series of strands that are threaded through the spindles; the lifters or positors for displacing the stay wire from the guides; and '70 the beat ers or presser-feet which, when the stay wire is brought within their reach, move it to within the operation of the tools of the twister-heads and hold it there. These beaters or presser-feet are formed to straddle the strands, as explained in our said application Serial No. 262,966, and thus also serve as line wire guides.

m denotes a stay wire cutter beside the marginal twister (No. 4) at the feed-roll side of the series. This cutter may sever the stay either just before or just after the operation of said marginal twister. Inthe former case the marginal twister would be a simple end twister as shown; in the latter case it would be a looper and twister.

a is a middle cutter which may or may not be used to sever the stay wire in two either before or after the operation ofthe twisters. If used before, the two middle or innermost twisters (No. 1) would be merely end twisters each rotatable in a reverse d1;

rection to the succeeding twisters' of the same series. If used after, or if not used at all, the saidmiddle twisters would be loope'rs and tw'isters as shown. p

The feed-rolls 7L feed a surplus of the stay wire beyond the marginal twister farthestffrom the feed-rolls, and in operation the looping tools of the one series of twisters take up the, material for the loops from such surplus, while the looping tools of the other series of twisters draw in the necessary material through the feed-rolls h, which allow the stay wire to' slip therethrough as stated in our said application Serial N0. 262,966.

A gripper 0 may be used beyond the marginal twister farthest from the feed-rolls, for tensioning the stay wire against the resistance of the looping tools, especially if the knife 11 be operated preliminary to the stay-applying operation. such gripper is not indispensable, since the stay wire may be suliiciently held by the presser-feet 7b.

Ifiinstead of the feed-rolls h, a presevered stay length should be fed to the twisters, as in ourformer Patent No. 721,605, dated Feb. 24, 1908, the wire being straight however, in such case the stay length 'so severedvwould of course have the necessary surplus at both ends, and the use of grippers 0 at both sides of the machine would be preferable; as in the Kelley & Reid stay-machine Patents Nos. 721,567 and 721,568, where a stay length was furnished with the required surplus at both ends and grippers for tensioning were employed at both sides.

It will be noticed that thetwo series of drivers d areidentical except for their opposite disposition, and the drivers of each series are set at successively different angles for operating the twistersin sequence in the same 'manner as in our said application Serial No. 262,966.
