j I eeann v RICHARD P. SCHMIDT, OF OTTAWA, ILLINOIS f BARBED Winn srnrneme' nnvron Application filed February '14, 1931. Serial No. 515,815. I I

' This invention relatesto improvements in reeling and unreeling apparatus and more particularly to apparatus for stringing and jpurpose of establishing boundaries, enclosing fields, andthe like. Where barbed Wire is so used, it' is extremely dilhcult and in many instances dangerous to handle. This is true to the extent that oftentimes the wire fence is broken down and the wire left to deteriorate rather :than taking down the wire N and reeling it for future use. i

"the provision of simple and .efiicientapparatus by which wire, particularly barbed Wi re,-may be unreeled from a roll or the like and strung-to form a fence, and thereafter, when 1 occasion demands, be again reeled, Wherebythe fence maybe put up, taken down, and {moved from place to place as necessary; A furthercbject is to provide an improved wire stringing, apparatus by which wire may be unreeled and strung under tension to form a fence. A further ob-- ject is to provide a wire stringing apparatus in which the wire roll is braked against free spinning or turning to thus enable the wire 33 to be laid or strung under tension. A fur ther obgect is to provide a wire reellng device I by which wire extending in lengths may be coiled on a reel or spool for transporting or for subsequent restringing. 1% further obect sto provide an apparatus for reellng and stringing wire, which necessitates" only one. operator, vthereby"materially reducing time and labor costs in setting up and taking down fences. a a Other objects will be in part obviousand in. part hereinafter pointed out in connection with the following analysis of this invention, wherein is illustrated one of the variouspossible embodiments of the present invention, together withcertain modificationsin de-.

Fig. 3 is a side View of the spool structure. Fig. l is a further View of the spool. Fig. 5 is a detail in sectionof the wire roll adjusting means. i

Referring now to the drawings, I provide a wheeled carriage constituted by the Wheels 10, 11 and axle 12, the wheels being freely rotatable on the axle. A normally U-shaped' draft yoke, generally indicated at 13, has at the end of the

side pieces

14, 15, thereof, en larged hubs 16 through which axle 12'extends. Cotter pins 17 or equivalent restraining means are provided in suitable apertures in tie axle and function to hold the draft yoke in properly assembled relation therewith. One side piece 15 of the draft yoke is hinged as at 18. adj acent the cross piece there of, and upon removal of its associated cotter:

pin from the axle, the hinged section of the side piece 15 may be swung from its normal! positionaway from the axle (asshown'in dotted lines, Fig. 2) to thus permit the wheel 10 of the carriage structure tobe removed from the axle forpurposes tobe hereinafterv described,

The draft yoke 011 its cross piece carries a 8L hinge 26, one leaf "of which is fixed with the draft yoke and the other leaf being bolted or I otherwise secured to a combined pull andv I brake bar 27. The bar 27 may comprise two

strapirons

27a, 27b, spaced at their front ends for the receptionof a handle 30 which may be readily grasped by an operator. The other ends of the strap irons, which extend rearwardly, are spaced bya tool box 46 to the bottom of which the other leaf of the hinge 26 is secured andby a block 82, preferably of l wood, which extends beyond the ends of the straps and functions as a brake. shoe, aswill be hereinafter described more fully. The box 46 and the braking block 82am bolted or otherwise secured to the straps as at 33;

The spool or reel on which; the wire roll is mountable and from which it may be 1111- reeled is comprised of spaced sets of

cross arms

35, 36 secured at right angles to each other by hub plates 37. Two sets of toothed slots 38 are provided in each of the

cross arms

35, 36, the slots being spaced substantially equi-distantly from the center of the spool as defined by the junction of the cross arms. Extending transversely bet veen the sets of cross arms are a plurality of transverse elements having their end portions interiorly threaded for engagement with threaded studs or bolts 41 which extend through the toothed slots 38, the heads of the bolts being disposed exteriorly of the spool. In mounting a roll of wire which is to be strung on the spool, one set of

cross arms

35, 36 forming one side of the spool is removed by suitable inithr ading of bolts 1-1 to permit disconnection from the transverse bars 40, and the roll of wire, which is annular in conformation, is threaded. over the bars to rest on the under cross arms, or other side of the spool, which may be disposed he i zontally. Thereupon the cross arms previously removed are laid on the coil and connection made with bars -10 as by threading the bolts 41 lightly into said bars. lly reason of the toothed slots 38, the bars may there upon be adjusted into a position to securely engage the interior of the roll, and the bolts 41 tightened, whereby the wire roll securely mounted on the spool and prevented from turning or spinning ith respect thereto.

Vhen it is desired to mount the spool carrying the wire coil on the carriage, the cotter pin 17 adjacent the hinged section of side piece 15 is removed, and the side piece 15 of draft yoke 13 is swung away from the axle, permitting removal of wheel 10. The spool is then threaded on to the axle 12, it being understood that the axle extends through the hub plates ofthe spool. The wheel 10 is thereupon put back on axle 1,2, the si le piece 15 of the draft yoke swung inwardly over the axle 12 and cotter pin 17 is inserted whereupon the wheels 10, 11 are properly spaced by the spool, the spool being ticreupon properly mounted wita respect to the carriage for the operation of stringing.

Itwill be understood that during the operation of mounting the spool on the carriage, the pull and brake bar 27 is moved so that the brake shoe 32 is raised, as permitted by hinge 26. Upon lowering of the bar 27 into substantially horizontal position as shown in Fig. 1, the brake shoe 32 engages the wire coil, and the barbs of the wire are imbedded into the wood piece which consequently acts as a brake preventing the spool from free turning.

To string the wire, the free end of the wire coil is nailed or otherwise secured to a post, such as a corner post, and the operator pulls the carriage in the direction of the fence to be laid. As draft is so exerted, the end of the pull bar 27 carrying the brake 32 is J automatically toggled downwardly, the braking force exerted by the shoe of the wire coil being thus proportional and responsive to the draft force necessary to advance the carriage. This retardation of spinning of the wire roll thus permits the wire to be strung under tension. The operator, with suitable tools carried in the tool box 46, may, as the carriage is advanced, secure the tensioned wire to the post or posts forming a part of the fence structure.

By reference to Figs. 3 and 4:, it will be seen that the ends of the

cross arms

35, 36 forming the spool structure are extended to form handle portions which may be readily grasped by the operator in taking down fence wire and coiling it on the reel or spool. The reeling of lengths of wire, such as encountered when taking down a fence, may be effected by securing a free end of the wire to a transverse bar 40 of the spool, and thereafter, by grasping handles 50 of the spool, turning the same about axle 12 of the carriage. As the wire is reeled, the carriage may roll due to the free mounting of the wheels 1O, 11 on axle 12, and the carriage is thus advanced, without attention of the operator, as the length of wire is restrung on the spool. I

After a fence has been taken down and the wire reeled as hereinbefore described, the spool carrying the roll may be removed from the carriage and stored, or the rolls may be removed from the spools and tied for transport or storage, or for further restraining.

Thus the apparatus as above described has the advantage that it requires only one operator and further avoids the possibility of the operator being cut by the barbs of the wire. By reason of the hinged relation of the pull and brake bar 27 to the draft yoke 13, the brake shoe 32 carried by the brakebar is automatically adj ustcd to effect proper braking whereby to prevent the spool of wire from spinning, regardless of the size of the roll or coil of wire mounted on the spool. The brake shoe 32 may be readily removed when worn and a new shoe replaced. The design and structure of the apparatus is such that the wire, either in stringing or reeling, is maintained at all times at a sufficient height from the ground as to keep it free and clear of dirt, weeds, bushes, and the like.

lVithout further analysis the foregoing will so fully reveal the gist of this invention that others can by applying current knowledge readily adapt it for various applications withoutomitting certain features that, from the standpoint of the prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention, and therefore such adaptations should and are intended to be comprehended within the meaning and range of equivalency of the following claims.
