1'0 alt whmn it may concern Be it known that I, FERDINAND SToRnEUR, a subject of the King of'Belgium, residing at Buenos Aires, Argentina, have invented certain new and useful Improvements in fire- Stretchers for Fencing Purposes, substantially as hereinafter described and claimed. My invention pertains to wire stretchers; and it consists in the peculiar and advantalo geous fence-wire stretcher hereinafter described and particularly pointed out in the claim appended. f

In the accompanying drawings, Figure 1 is a perspective view of my improved wirestretcher in its operative position,.the same being shown with one of its frame -plates partly broken away.- Fig. 2 is a detail plan view, partly in section, illustrating one of the shafts of the stretcherin position to rotate and the other as secured against rotation; and Fig. 3 is a perspective view of one of the shafts of the stretcher removed from the frame thereof.

Similar letters of reference designate corresponding parts in all of the views of the draw- 2 5 ings, referring to which A is a post designed to be fixed at its lower end in the ground, and B is the main frame of my improved wire-stretcher. Said frame comprises a plate Ct, having circular apertures 1) adjacent to its ends, a'pla'te' c,'disp'osed at the opposite side of the. post with reference to the plate a and having angular apertures 61 arranged adjacent to its ends and in transverse alinement with the apertures b, and a 3: bolt 6, which extends through the plates and the post A and is threaded at one'end, as indicated by f, for the engagement of a nut g, which serves to secure it in position, and thereby hold the plates tight against the opposite sides of the post.

O C are the shafts of the stretcher. These shafts are mounted in the frame-plates a c at opposite sides of the postAand are similar in construction. For the latter reason a detailed description of the shaft'shown in Fig. 3 will suiflce to impart an exact understanding of both. Said shaft comprises a main portion h of circular form in cross-section, having an aperture i at an intermediate point of its length and also having an angular end j for the engagement of a crank, (not shown,) an integral flange .70 at the opposite end of said portion h, an integral angular portion Z, corresponding in shape to the angular apertures (Z of frame-plate c at the outer side of the 5 5 flange 70, an integral circular portion on at the outer end of the angular. portion Z, and a collar n, shrunk or otherwise secured on the end of said circular portion m. The shafts C O are mounted in the frame B in the manner shown in Fig. 1-2. e., with their circular portions h in the circular apertures b of frameplate aand their opposite end portions in the angular apertures dof the frame-plate c. The wires to be stretched and held under tension are secured in the apertures t' of the shafts and are designed to be wound on said shafts after the manner shown in Fig. 1.

In practice when it is desired to stretch and take up slack of one of the wires the shaft complementary to said wire is moved endwise by the interposition of a prying instrument between its flange 7c and the frame-plate 0, so as to withdraw its angular portion Z from the angular aperture (1 of the, plate and dispose its circular portion m in said aperture. The shaft is then rotated on its axis, through the medium of a crank applied to its angular end j, until the wire is sufficiently taut, after which the shaft is moved endwise in the direction opposite to that first mentioned to replace its angular portion Z in the aperture d of the frame-plate c and hold it against rotation WVith this done'a pin D is placed in an aperturep, provided in the portion m of the shaft, and the ends of said pin are bent in opposite directions, Fig. 1, when the shaft will be securely held against both endwise and axial movement, and casual loosening 'of the wire will be precluded. a o

It will be readily appreciated from the foregoing that my improved stretcher is adapted to connect two wires to a' common post in such manner that either wire may be rendered-taut and securedin such conditionindependent of 5 the other, also that either wire may be rendered loose or may be disconnected from the post without in any way affecting the other.

It will further be appreciated that when the wires at opposite sides of the post are placed I00 transverse aline1nent with the circular apertures, a transverse bolt extending through the plates and the post, and fixedly connecting the latter to the former, and transverse shafts disposed at opposite sides of the post; each of said shafts having a portion h of circular form in cross-section, journaled in a circular aperture of one plate, and an angular endj, disposed at outer side of said plate, and also having a flange 7c, arranged at the inner side of the other plate, an angular portion Z, at the outer side of the flange, disposed in the angular aperture of the latter plate, and an apertured, circular portion m, of less size than the angular portion Z, arranged at the outer end of said portion Z, collars secured on the outer ends of the portions or of the shafts, and pins relnovably secured in the apertures in said portion m.

In witness whereof I have hereunto set my hand in presence of two Witnesses.
