.To all whom it may concern:

- Be it known-that we, RoBnn'r KIRKWOOD and JOHN W. KIMBE LING, citizens of the United States, residing at Moran, in the county of Clinton, State of Indiana, have invented a new and useful Fence-Machine,-

of which the following is a specification.

ThlS invention relates to fence stretching machines, and has for its principal object to provide a fence stretcher of very simple and economical construction by which a wire fence may be drawn as taut as d'esired, and

which may be readilyshifted from-place to place during or after the erection of the fence.

'A- further object of the invention is to provide a device of this type in which the fence may be adjusted for the pur oseof exerting I of the fence.v A still further object of the invention is to provide a very simple and effective form of ence clamp in which the, clamping force exerted is in proportion to the 'tensional strain exerted during the stretching operation. With these and other objects in view, as will more fully hereinafter appear, the invention consists inqcertain novel features of inafter fully describe construction and arran ement of parts,.hered, illustrated in the accompanying drawings,- and particularly pointed out in the appended claims, it being understood that various changes in the form,

propor tions,"'size and minor details of the structure may be madewithout departing from the s int or sacrificing any of the advantages o the invention. i

. In. theaccompanying draWings:Figure' 1 is a perspectiveview ofa fence stretchingmachine constructed in accordance with the invention. Fig. 2 is a sectional plan view through the fence clamps, the ;latter being shownin open position. Fig. 3 is a sectional plan view showing the gearing and chain winding mechanism.

Similar numerals of reference are em-- ployed to indicate corresponding parts throughout the several figures of the drawings. The clam includes a pair of angle bars I '10, one of w ich carries a series of books 1.1.

and .the other aseries of .eye 12, these forming a hingedjoint ofsuch nature as to permit ready couplin and uncoupling.

Pro'ectm om the angle. bars are two A sets 0 brae e'ts 13-that are arranged for the reception of hooks '14, these being arranged turned 'or the purpose of winding chain 18 and drawing the clamps 10 in the throug at the ends of chain sections 15 and connected thereto by suitable turn buckles 16'. It will be noted that the'brackets 13 are rigidly securedto the angle bars and project a considerable distance beyond the rear edges of said bars so that, they may beconveniently used as handles in the closing of the clampmembers on the fence; The adjacent ends of the chains 15 are connected by a rin 17 to which is, also, connected I a stretc g chain 18 the latter passing over a chain drum 19 which may be turned for the purpose of winding up the chain 18.

.At a short distance from the clamps is arranged a frame comprising a pair of parallel posts 20 connected together by upper and lower blocks 21 and arranged to rest on a suitable sill plate 22. These posts, which constitute the draft frame, are held from movement inthe direction of the clamp by spacing bars 25 .that rest at one end against 13 e fence post a, and at the 0 posite end against the posts or the spacer b ocks 21.

" The draft frame is provided with bearings I for the reception of a short transverse shaft 27 to which the winding drum 19 is secured. This shaft, also, carries a worm wheel 28 that is enga ed by a worm29, the latter being carried a worm shaft 30 that is j ournaled in suitab e brackets 31 that extend between and serve as additional connections for the posts 20. At the rear end. of the worm shaft is an .0 crating crank 32 which may be up the direction of the draft frame.

In operation, the-clamping bars, separated from each other, are placed on o pos1te sides of the fence to be stretched an their'hooks and e es are then connected together the fence. The brackets 18 are then grasped and used as'handles in the preliminary folding. of the angle bars'on the fence. The hooks 14 are then passed loosely through the brackets 13, and on turnin the crank 32, the chain 18 will be woun up. The first effect of themovement will be to 1 draw the clamping bars toward each other and firmly grip the fence between such bars,

and this clamping action increases inforce as the tensional strain exerted on the fence increases.

I Should the, upper ortion of the fence be stretched more tlght y than the lower por- .of the upper end of the draft frame and con-' clam s,

- there 'is'some mg extended-to formoperatinghandles in the preliminary clamping offthe'fence, a hook arexercising a cam-like action thereon to draw the clamping bars together, a central draft s are connected,

When the fence is under severe strain, danger. of lateral displacement of the draft frame, and to prevent this, stay chains or ropes 35 may be employed, these chains being connected to the opposite, sides nected to any suitable anchor, such for instance as (stakes embedded in the ground.

It Willlbe seen that the fence is firmly clamped between the angle bars, the fence being bent at two points so that it will, be firmlyl'ocked. I ..e claimg 1.
