which are used for the purpose of c To all whom may n Be it known that ll Jmrns citizen of the United r 1dr Hannibal, in the coon of Marion and of Missouri, have inve v. d new and useful improvements in FCHCS-blfiifiPS, of which the following is specification, I

This invention relates to fence cloinps lsiupin and noldi Wire fence fabric 1 v the pur pose of sti cliing tlr one to hold it in tight condition While being riled upon or otherwise connected with the fence posts.

The invention has its object to produce a simple and improved clamp which may be readily cpplieduto fence fabric and which will be so onstructed that exerted on the clay proper direction. will to to increase the grip thereof on the 'Wii' fabric.

A further object of the invention is to produce clemping device of simple and improved construction includ'ng a pair of jaws that ar seperebly conner togcthcr said jaws being detecliebly connected with. a gle device with which the draft is connected in such a fashion as to draw the clamps tightly in the direction of each other to engage 1e fabric ti're ebetween,

A further object of lDfV$l ion simplify and improve construction and arrangement of the detailed parts of the de-v With these and other ends in View Wliicri will readily appear-it's the nature of the in- -vention is better onderstood the same consists in nnnovsd coim suction novel errengemenl and combir w will be liereinefter fu ly described ticulsrly pointed out v. l claims.

in the accompany drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details tiorein exhibited, but that changes, alterations end modifies.- tions Within the scope of the cieims may be resorted to when desired In the drawings,-

Figure 1 is a perspective view sliowi" improved clcinp arranged position for op eration.

Fig. 2 is e plan iew,

Fig. is e sectional View on line Tile clamping Fig. 4E a, norizontel sectional YlGW' taken on the line .---r in 3a is View in side elevation of one oi the clamping jaws and the clamping bar can tied thereby.

Qorresponding parts in the several fi ures are denoted b'v like characters or retlerence. ms wh ch nave been n being of noproniina-tely rectanguizir shape are provided at one end thereof with in'terengeging' hinge lugs 16 for the passage e pintle or pivot member 17 whereby the jaws are pivoteily conn ecter'itogetlier. The jaws are provided in their opposed faces with rectangular recesses 1.8 of proper dimensions to receive it clampber 19. said bar consisting preferably of e piece of by ...ncli cnntling' or? proper length, it being understood that the length oi" the clamping bars shall be about equal to the Width of the fence nmterial in connection with which the device is to be used, and preferably of a length soinewl'iet exceeding the Width of the fence nmteriel. The clamps fng; bars may be secured in the recesses-of tlic ective jaws means of screws or by stoning members of any description, The

wing bars are also provided on theirop- ;so; ices with interengaging strips 21 of steel or other suitable niaterinb said strips beingprefercbly slightly inset in the face or the clamping bars and secured by screws or other fastening means the purpose of said strigs being to crimp the Wire fabric engeged tberebv so tint said fabric will be socurelv gripped by the clamping device.

on is provided At its outer corner, dist-sot from the hinge lo 16, with a pair of proj ction: 21 the nter .isces of which are provided will pin opivot member 2% com which 1s inserted be- The toggle links reception of ried by e toggle link tween the pro ections are pivotelly connected with head block 26, Wliicb letter carries a clevis 27 whereby it may be connected with a source of power,

' wire fabric that is to be stretched, the lugs v 16 being inserted through an opening in the fabric, after which, the pintle or pivot member is replaced. By moving ,thejaWs in the direction of each other above the axis of the pivot member 17, the clamping bars will engage opposite sides of the fabric which will e crimped and held securely therebetween by the action of the strips 21. The toggle links are now connected with the jaws by inserting the pins 24: in the recesses 23, after which by pulling on the head block 26, "the jaws will become tightened on the fabric, and the latter will be placed under tensile strain. It is obvious that power of any kind or description may be used for exerting the desired pull or tension on the head block;

the clevis member may be connected with the end of a rope or cable leading to a windlass operated manually or by animals, or animal power may be applied directly to the clevis. Lever or other power may also be employed when deemed desirable or expedient.

As will be seen from the foregoing description, the improved fence clamping device is extremely simple in its construction, and it is capable of being produced at a very moderate expense, the clamping jaws being made, as Well as the head block, preferably of cast iron, while the clamping bars are nothing more than pieces of ordinary scantling having metallic strips mounted on the Owing to its structure as herein described, the clamping jaws may be very quickly disengaged and adjusted adjacent to opposite faces of the wire fabric that is to be stretched, and the general construction of the device is of such a nature as to render it thoroughly effective for the purposes for which it is provided.

Having thus described the invention, what I is claimed as new, is

1. In a fence clamp, a pair of jaws of substantially rectangular form. having interengaging hinge lugs and a pivot member engaging the same, said jaws being provided at the outer corners of the free ends thereof ,with pairs of projections having recesses in their-outer faces, a toggle device including a head block, and links pivotally connected therewith, said links extending between the projections and having transverse pins engaging the recesses in said projections, and a clevis member connected with the head block, said clamping jaws being provided with recesses in the faces thereof and with clamping bars secured in said recesses.

2. In a fence clamp, a pair of jaws of substantiallyrectangular form having interengaging hinge lugs and a pivot member 811-- gaging the same, said jaws being provided at the outer corners of the free ends thereof clamping bars having crimping strips inset in the faces thereof and extending longitudinally thereof.

In testimony whereof I afiix my signature;

JAMES HASGALL.
