REGINALD cHAnLEs DUIGAN, or Mm ivrIA, VICTORIA, AUSTRALIA.
WIRE-STRAINER. I
To all whom it may concern: 7
Be it known that I, REGINALD CHARLES Doreen, a subject of the King of Great Britain, residing at Spring Plains,,Mia Mia, in the State of Victoria, Commonwealth of Australia, have invented certain new and useful Improvements in an Improved Wire- Strainer, of wlnch thefollowingis a specificatlon, reference belng had there nto the accompanying drawings, forming part This invention relates to an'improved wire strainer and refers more especially to van implement or device for straining'or tensioning' fencing wires though it will be understood that it is applicable to other purposes in which straining or tensioning a wire is necessary and that it may even be used as a hoist or the like for hauling or moving a load. I
The object of this invention is to provide a wire strainer of simple and inexpensive construction by which the operation of straining wires may be eifected while maintaining the same in a straight line and without bending or twisting the wires or damagin the same such as with serrated ri pers) while further the jointing of the two wires may be effected without sacrificing any of the advantage gained when releasing the strainer. I o i,
With the foregoing object outlined and with other objects in view,.which will appear as the description proceeds,v my invention consists in the novel features hereinafter described in detail, referencebeing'had, to the accompanying drawings in which I have shown two embodiments of the invention, and the said invention is fully disclosed in the following description andclaim.
Referring to the drawings.
Fig. 6 is a longitudinal section of a modified form of sliding piece showing slot covering extensions;
Fig. 7 is a view of the knot formed in the Specification of Letters Patent;
' t on-- gene when the straining is completed and the. implement removed.
. -I*ig. S is a plan of an alternative construc- In; constructing a strainer according to this invention Itake a 'piece' of .steel tube A about twelvet inches in length, having'a which forms a seat for: the pivoted handle oiylever C. At the extreme front end of this block B is provided a hook or nose piece I3 upon which the standing wire S is looped, the said hook ,being longitudinally slotted as at B forthe; accommodation of the strained .wir'e P, Thishook or nose piece, B. is'made slightly inclined. upward so that the loop of wire may be easily. released therefrom fwliei thestraining operation is completed.
Within the before describedslotted portion of the tube A is provided a pair ofgsliding pieces D and E thelfforward one of which formed I by the block B while the rear one E has ]a spring -E bearing againstthe vstop formed by the pin of thecentral ferrule A.
The sliding piece D is provided with a gripcurved recess D to afford a secure'grip for -;.the';wir'e. Similarly the sliding piece 'E has 'a gripper comprisingflaram E pivotedat r E? andbearing, against a shoulderjE which also has a slight curved recess E The disposition of the cam shaped grippers D and 1 vE upon. their pivot points I). and E relative'to the shoulders D and E respectively is such that the point of the cams are just prevented from passing by the shoulders D and E while the shape of the cams coincides with the recesses D and E so that a maximum leverage and gripping effect is obtained. These grippers D and E are connected to the pivoted lever or handle C upon opposite sides of the pivot point thereof by connecting rods D and E respectively so thatin operation while one is advancing Patented July 2, 1918. Application filed June 26, 1917 Serial Noi 176,951.
vDyhas a spring D bearing againstthe stop per whichcomprises a cam D (which is pref- .erably undercut) pivotedat D and bearng againsta shoulder-D wh ch has a slight pieces E and D toreci'p'ro'cate within the tubular base piece A, the two traveling always in opposite directions carrying "the wire forward on each forward movement and releasing the wire on the backward m ovement.
The handle, through the connecting rods,v gives a gripping tension to the cams when the 1 sliding p eces aregmov'ed forward and releases the cams when the pieces are moved rearward. In this way on each strfoke oii the handle a forward movement is ii'npa'rted tothe wire P by 'the one; gripper on one hi'ovement and by the other gripper on the other movement, the tension of the springsinaintainingthe grippers i'n co'ntact with the wlre.
lVhen the end of the strained wire P reaches the forward endof the implement it is inserted into the slot 13 of the nose piece B and passed 'throughthe loop'ofthe standing wire *8 The handle "C is then operated until sufficient tension has been placed on'the wire I when the two "wires P "and'S are joined together by twisting the wire P on tothe wires as shown in 7 andthe implement'may'b e removed by ie'leasing the grippers ;D and E on "the wire P and unhooking the-nose pi'ece' B from the-loop of thestanding-wir'e S. Thus no advantage gainedin the straining "opera tion is in anyway los't. Though-the implement herein described and illustrated is shown with the grippers slid'ingiwithin a tubular base piece or guideit will be understood th'at the said grippers andtheir supporting sliding 1)ieces=may be mounted u on aba-r'or' rod orapair of bars or=ro ds. In one such alternative construction Fig. 8 the base piece formed "of a rod "or bar or tribe A liavinga noserpiece or hook (such as B) atone end a'nd a p'ivotedhandle or lever (such as C) mounted adjacent thereto. Slidingpieces (such as D and E) carrying am shaped grippers (such as D and E are mounted externally on the said rod or bar oi-"tube Aivith springs "(such as D and E") wound around the said bar or rod or tube and bearing against suitable stops. The operation of an implement constructed in this manner is precisely the same as that previously K described.
From the foregoing, the construction and operation of my improved device willbe "readilvunderstood and while I have shown 'and'described the preferred embodiments of my invention, it "will be understood that va'riouscl'iai'i'ges and modifications may be niade-therein without departing from the "spiritot the invention or sacrificing any of the advantages of the same.
A wirestrainer comprising a tubular base piece slotted for a portion of its length and *provic'lediat its forward end with a fixed "block "ha-v'i parallel furcations spaced apartand-ektendiiig at right angles to the base piece for securing a wire loop to the "same, a handle pivotally connected to said block,slidingpieces located insaid tubular basepiece and each having an integral'jaw "provided with a shallow longitudinally curved groove, a movable jaw pivotally connected to each of theslidingpieces and having acurved surface adapted to'cooperate with one= of the curved grooves for gripping a second wire and moving the samethrough "the space between the furcations, hz'n'idles "integral with the movable =j'aws, links connecting the handles with the handle, a spring located inthe tubular base piece and having one end bearingagainst the fi-Xed block and its other end engaging one of the sliding pieces, and anotherspring-located in =the 'ba's'e piece" between the other sliding tpiece and' a fixed member in the'base piece. In 'testi'lno'ny whereof I havesigned my na meito"thisspecification inthe presence of tw o subscribingwitnesses.
