WIRE-FENCE MACHINE.

SPECIFICATION forming part of Letters Patent No. 362,439, dated May 3, 1887.

Application tiled March 8, 1886. Serial No. 194,4 1S. (No model.) I

To all whom it may concern:

Beit known that we, ANDREW J. FoRsYTHE and GEORGE W. FoEsYrHE, citizens of the United States, residing at Kokomo, 'in the county of Howard, State of Indiana, have invented certain new and useful Improvements in Wire'Fence Machines, of which the following is a specification, reference being had therein to the accompanying drawings. A,

This invention has relation to fence machines of thatclass which are constructed and adapted for thel purpose of twisting two or more wires forming the strands of the fence about pickets in order to secure them to the strands, and to do this at the place where the fence is intended to be and at the time that it is built; and the invention consists in certain features of construction hereinafter specified, and particularly pointed out in the claims.

Referring to the drawings, Figure lis aside elevation ofa machine' embodying our invention, aportion of the fence also being shown. Fig. 2 is a rear elevation, and Fig. 3 is afront elevation, ofthe machine. Figa is avertical section on thelinexxof Fig. 2. Fig. 5 is a rear elevation of the front plate of the frame-work of the machine. Fig. 6 is an illustration of a portion of afence, some of thestrands of which are provided with more coils in the twists-v Fig. 7 is a perspective thereof than others. of the cap-plate of the frame-work. Fig. 8 is a det-ail in perspective of the tension device, and Fig. 9 is a perspective of one of the twisters. Fig. l() is a similar view of a cam-lever employed in the machine.

Like letters indicate like parts in all the tigures of the drawings.

In thisclass of machines suitable pickets, or it may be ordinary laths, are secured between the strands of the fence, which usually consist each of two wires, by twisting said strands together between the pickets, the twisting being made in opposite directions between succeeding pickets, the object being to remove the coiling or twisting ofthe strands in front of the machine, which are produced as the work progresses.

As illustrated herein, the machine is adapted to twist five strands, each of the twisters consisting of agear-wheel the hub of whichis provided with apertures through which the wires are passed, and the series of such twisters are connected togetler by intermediate gears, one of which is ruiter-geared to a similar gear upon the driving-shaft of the machine, so that when said shaft is revolved all of the twisters are revolved, in order to secure the pickets in the strands, as above mentioned.

bearings A* for the-twistersmnd with other intermediate bearings, A, for the intermediate gears. The said plate is also provided with annular recesses A around two successive twister-bearings, At, and the bottomv of cach recess is perforated, as at A7, for a purpose hereinafter described. rIhe said plate A is also provided with an integral bracket, AS,

whichserves as a bearing for the power or driving shaft of t-he machine, and at its opposite edge it is recessed, as at A9, Fig. 5, for the more rigid attachment of an opposite drivingshaft bearing, 1*.

It will be seen from the description given that the plate A may be conveniently formed or cast in a single'piece vof iron, and that all of the bearings therein can in a like manner be finished by machine tools, and that the apertures through the spacing-lugs A may be conveniently drilled.

The back plate of the machine is upon its inner face substantially plain throughout, so that when placed upon the spacing-lugs and when the cap-piece 0,(see Fig. 7,) which may also be cast as a part of either the front or back plate, is arranged between them, suitable bolts, C', passing through both plates, serve to bind the frame-work firmlyinpperative position, with the twisters and intermediate gears properly supported for operation therein.

The rear face of the rear plate, D, is provided with integral picket-spacing` lugs D, which are plain or otherwise finished, so that their faces are in a true line with each other, whereby, when each succeeding picket to be secured in the strand is placed against the IOO , distance maybe determined and varied by inserting the bail in diilerent holes in the brackets E. The rear plate is also provided with similar bearings to that of thc front plate, and at points to register` therewith and opposite the recesses A" of the front plate the said rear plate, D, is provided with slots D?, and in said slots are supported cam-levers F, pivoted in lugs D", formed on the plate D.

A lever, G, pivoted as at G', near the bottom of the rear plate, D, and provided with a lift ing-pawl, G, serves the purpose of lift-ing and intermittingly moving the frame-work as the building of the fence progresses.

rlhe twisters consist of gears H, the hubs II of which arc adapted to tit the bearings A, and are provided with pairs of perforations H2 H, the former being wider apart and of larger diameter than the latter, in order to adapt the former to receive and twist coarser wires constituting the fence-strand, and the latter to receive and twist finer wires.

I represents the crank for turning the driving or power shaft I of the machine, upon which is mounted a bevel-gear, I, which meshes with a companion, I, mounted on an intermediate gear, J, of the series of twisters and other intermediate gears J. A remova ble bracket, I', serves as one ot' the bearings for the driving-shaft I, and is secured by bolts, I5, passing into the front plate, A, the base of the bracket entering the slot A" therein.

Now, it will be observed from the description heretofore given that when all et the twisters and intermediate gears are meshing with each other, and when the wires II, constituting the strands, are passing through the twisters, the turning ol' the crank I will give motion to the twisters so as to coil the strands K upon cach other between the pickets, as well as in a manner and to a certain extcntin front of the machine, as the work progresses. This ceiling or twisting is uncoiled at a subsequent operation by turning the crank in an opposite direction. Now, when it is desired to change the direction of the fence in regard to a vertical plane-that is', to ascend or descend a hill,the former case being illustrated in Fig. 6--it is preferable to change the inclination of the pickets of the fence with relation to a vertical line, and this we accomplish, as before stated, by increasing the number of coils between'the pickets in the lower strands only of the fence; and to change direction to descend the number of eoilsbetween the pickets in the upper strands are increased. To provide for a change of this character in the operation of the machine, we throw out of mesh, and therefore out of operation, at a desired time, either the upper or the lower twisters of the machine, as desired, and we do this by the following mechanism: The canrlevers F-as, for cxample, lthe upper pair, as shown in Figs. l and 4-are elevated, so that the twisters II, against which they bear, are forced to the front and into the recesses A, against the tension of a spring or springs, L, which arc bent to pass through the openings A7 in the bottoms of the recesses and to bear againstthc front face ofthe twister. In this manner the said twister is thrown out ot mesh with thc intermediate gear, J, so that thetwisters dcpending upon thc one thrown out ol' mesh for motion remain idle, while the remaining twisters in the series may be operatcdby the driving-shaft. As shown in Fig. l, the upper pair of twisters are thrown out of operation, so that the lower three twisters may be opel'- ated to give an additional number of coils to the strands passing therethrough. In a like manner the twister next below the drivingshaft may be thrown out ot' operation while the one next above may be in mesh, so that an increased number oi' coils may bc pnt between the pickets in the lower strands ot the fence, whereby the upper ends of the pickets shall. be separated farther from each other than their lower ends.

As usual in this class ot machines, tension devices are used in advance of the machine, to control the delivery of the wire vconstituting the strands from the spools from which they are taken. In this instance we employ as a tension device guidingblocks, M, secured to a post or posts, lll', and having a sliding clamp, M, secured in the blocks M by means of a bolt, M, and a hand-nut, M", for the purpose ol' drawing the block M snugly against the wire K, so as to maintain snllicient tension thereon.

The operation of the machine will be understood from the description already given, and it is apparent that it can be used in constructing l'enccs with five or any less number of strands, three being shown in Fig. 6.

le do not claim, broadly, the combination of a series of twisters with devices adapted to throw 011e or more of the twisters out of contact with the twister-operating mechanism.

Having thus fully described our invention and its operation, what we claim, and desire to secure by Letters Patent, is-

l. In a machine of the class described, a series of twisters and a lever arranged to remove and retain one of the twisters out of contact with the remaining twisting mechanism, plates for supporting the twisters and lever, and means for returning the removed twister into contact with an adjacent gear-substantially as specified.
