COMBINED WIRE STRETCI-IEB AND SPLICER.

Application filed February 27, 1923.

To aZZ whom it may concern:

Be it known that we, JOHN Eton-n and BRUCE hlonrn'rii MAoLnon, subjects of the King of Great Britain, and residents of the city of Lethbridge, in the Province of Alberta and Dominion of Canada, have inventcd certain new and useful Improvements in Combined Wire Stretchers and Splicers, of which the following is a specification.

This invention relates to improvements in combined wire stretchers and splicers and the objects of the invention are to provide a light, efficient and simply constructed tool of this character, in which the several parts will satisfactorily perform the various functions required of them.

With the foregoing and other objects in view, the invention consists essentially in the novel construction and arrangement of pants as described in the present specification and illustrated by the accompanying drawings that form part of the same.

Referring now to the drawings, in which like characters of reference indicate corresponding parts in each figure,

Figure 1 is a plan view embodying the invention and showing loose wires in position preparatory to splicing.

Figure 2 is a similar View showing the stretcher reversed.

Figure 3 is a detail of the swivel mounted clamp.

Figure 4 is a detail of the clamping member.

Figure 5 is a plan view of the stretcher.

showing wire stretched preparatory to splicmg.

Figure 6 is a similar view of the next position preparatory to splicing, in dotted lines.

Figure 7 is a plan view showing the final position of stretcher and taut wires for splicing.

In the drawings, in which an example of the invention is illustrated, A designates the device as a whole consisting of a main member 10 pointed at its lower end 11 to be stuck into the ground when, desired and suitably curved at its upper end to form the fixed arm 12.

14 is a swinging arm suitably curved in opposition to the arm 12 and pivotally mounted on the arm 12 at 13. This arm 14 is also adjustable by means of a series of holes 15 therein, one of which designed to register in turn with a hole 16 in the arm 12.

Serial No. 621,591.

18 is a hole in the arm 14 apart from the series 15 and is designed to register with a hole 19 in the main member 10 to receive therethro-ugh a securing pin 20 carried by the handle 10 and adapted when in use to hold the swinging arm 14 fixedly in position.

It will be noted that the semicircular formed swinging arm 14 is adapted to extend along and lie snugly against the arm 12, thereby ensuring strength as well as efliciency in operation.

Adjacent the outer ends of the arms 12 and 14 are the clamping members 22 and 23,

one of which is mounted on the rear side of g the arm and the other on the front of the arm. These clamps comprise a fixed portion 24, here shown as having a concaved face and a pivo-tally mounted cam-shaped member 25 provided with teeth 26 and a handle 27 and adapted in operation to engage with the portion 24 to grip therebetween the wire.

Pivotally mounted at 28 intermediate of the ends of the member 12, is a swivel member 29 on which in turn is mounted a clamp 30 of similar construction to the clamp 23.

31 and 32 are the wires.

33 is a spring for the clamp 22 connecting the arm of the clamp 22 with the swinging arm, whereby the clamp 22 is automatically held in closed position.

With regard to the hole in the swinging arm designed to register with the orifice or hole in the main member 10 and through which the pin is placed to hold the arm in position, this is for the purpose of stretchving loose wires and for holding the device in position for splicing the loose ends of stretched wires. All the other holes in the swinging arm are for the purpose of holding the stretcher at any point during the stretching of wire in what is known as the reverse pull or push of the handle 10 away from the operator. These holes in difierent places enable the operator to hold and fasten the stretcher at any point in the reverse stretch by simply dropping the bolt 17 into the hole which may be in proper place for purpose.

To splice loose wires, fasten both the wires 31 and 32 in the clamp 23, place one wire 81 in clamp 22 and the end of the wire 32 place on the opposite side of the arm 14 to that of the clamp 22. Give wire 32 a half turn around the wire 31 and place spike be' tween the wires and turn it four or five times and the splice is made, see "Figures 1, 2 and 7. v

To stretch wire, place the Wire 31 in the swivel clamp and tap clamp home securely with hammer or clippers, leaving the loose end of wire 31 long enough to extend across to clamp 22 when stretcher isin position. Then stretch movable arm 14 out to the left as far as it Will go and place wire 32 in clamp 22. The loose end of wire 32 must be long enough to reach clamp 23 when the handle of stretcher isvpushed over to the right as far as it will go.

With the spring on handle of clamp 22, it will grip the wire 32 automatically when inward movement of the stretcher is-begun. The finish .of this pull is illustrated in Figure 5. i

The handle is then drawn to the right and in this manner the wire is stretched. Then push the handle of stretcher to the left again un-til'itis back inits former position,

and repeat these stretches until wire is tight enough to suit. The handle of the stretcher is then drawn to such a position that the orifice therein registers with the orifice in the arm 14:,therebyholding the stretcher in position for splicing the loose ends.

The loose end of the wire 31 is then given a half turn over wire 32 beyond clamp 22 and the loose end of wire 32 is given a half turn over wire 31 to the right of clamp 30, see Figure 7, and then the spike or handle of the wire clippers is placed between the two wires and turned until the wires are securely spliced between the arms. Then open clamps and remove stretcher and thewiork is done.

As many changes could be made in the above construction and many apparently widely diflerent embodiments of our invention withinthe scope of the claims, con structed without departing from the spirit or scopethereof, it is intended that all matter containedin the accompanyingspecification and drawings shall be interpreted as illustrative and not in a limiting sense.

hat we claim as our invention is:

1. A tool of the character described, comprising in combination, a handle member having a rigid arm, a swinging arm carried by the rigid arm, and means for retaining the swinging arm in position, means for adjusting said arm including a series of orifices designed to register individually with an orifice in the rigid arm, and pivotal bolt means adapted to extendthrough said orifices, clamping means for said arms, spring actuated means for closing clamping means, and clamping means swivel mounted on the rigid arm.

2. In a tool of the character described, the combination with a stem, a rigid arm formed on the stem, a second arm swingingly mounted on the rigid arm, clamping means adj acentthe outer ends of said arms, and a clamping member pivotally mounted on the rigid arm intermediate of the swing ing arm, and the clamping .member at the outer end thereof.

8. In a tool of the character described, the combination with a rigid arm, and a swingingly mounted arm having clamping means thereon, of a clamping member pivotally mounted on the rigid arm, intermediate of the swinging arm,'and the clamping means thereon, a plurality of orifices in the swinging arm adapted to individually register with orifices in the rigid arm, and pin securing means through said orifices whereby the swingingly mounted arm is fixedly and adjustably retained in position.

In witness whereof we have hereuntoset our hands in the presence of two witnesses.
