Specification of Letters Patent.

To all whom it may concern.-

Be it known that I, JOHN B. ADAMS, Jr., a citizen of the United States, residing at Malden, in the county of Ulster and State of New York, have invented certain new and useful Improvements in Wire-Stretchers, of which the following is a specification.

My invention pertains to improvements in what may be termed wire-stretching devices. Its object is to provide for effectively stressing or stretching the wire, as in stringing or stretching it in osition; among other purposes, as for wireences. It is also adapted as a wire-cutter as well as a staple-puller.

Said invention consists of certain structural features, substantially as hereinafter fully disclosed, and sp ecifically pointed out by the claims.

In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure 1 is a perspective view showing said invention as applied for use as a stretcher. Fig. 2 is a like view with the stressinglever in its initial position, as when performing the stressing or stretching operation. Fig. 8 is a view showing the applicatlon of the device as a staple-puller. Fig. 4is a view suggesting the use of the device as a wire-cut-v ter. Fig. 5 is a disassembled view of the stressing or stretching lever.

In carrying out my invention I provide what maybe styled a dog 1, having practically the outline of the letter s, with one terminal pointed or formin a claw 1, effective for being readily embedd ed in a post-for instance, in securing a purchase therefor for disclosing the present use thereof. Said dog has its opposite terminal reversely curved outward, and to the same is pivoted by a pivot-bolt 2 the right-angled or outturned end portion of a manually-actuated lever 2. Said dog has its latter reversely-curved terminal equipped with a correspondingly curved blade 3, with its cutting or effective edge conforming to the concavity of the curvature thereof and that of said terminal. The lever 2 is equipped at .its angle also with a curved blade 4, which has its convexed cuttin edge presented toward and cooperating wit 1 the concaved cutting edge of the blade 3 for effectiveness as a wire-cutter, the use of which is illustrated herein. Said dog has also an outstanding projection or lug 1 presented toward and occupying a plane parallel with the lever 2, said projectlon or lug having two or more apertures 1, into either of which is adapted to be placed or adjusted a pin 5, primarily for formin a stop for limiting the inward movement 0 said lever in effecting the required wire stressing or stretching operation. Also it is noted that by means of the adjustability of the position of the stop or pin 5 any variation in the thickness or cross-section of the post may be compensated in effecting the requisite wire stressing or stretchin operation by the action or movement of the lever 2, which is controlled by the engagement of the latter with said stop or pin.

he lever 2 is also equipped with a clasp 6, effective to grip or engage the wire and comprising, preferably, a spring-metal piece 6?, with its freeend deflected outward and having its base portion screwed or secured to said lever.

It is obvious that with the dog applied to the post, as indicated, and the wire rippe by the clasp 6 by suitably actuatlng the lever 2 the stretching or stressing operation may be readily effected, the latter being controlled or limited in its movement by the sto 5.

, s suggested by Fig. 3, the device may be used for the removal of staples from a post or other part In Fi 4 the contrivance is shown as employed or severing wire.

I claim- 1. A device of the character described, comprising an S-shaped dog eflective to be engaged with a bearing and a manually-actuated lever having a right-angled. terminal pivoted to one terminal of said dog and equipped with a clasp said lever being adapt ed for movement toward said dog, and means for limiting its movement in that direction.

2. A device of the character described, comprising an S-shaped dog efiective for engagement with a bearing and havin intermediately of its terminals an outstan ing lug provided with a lateral stop, and a manuallyactuated lever having a right-angled terminal pivoted to one terminal of said dog and equip ed with a wire-engaging clasp.

3. device of the character described,

comprising an S-shaped dog equipped with a curved blade and a manuallyeactuated lever having a right-angled terminal and armed at its angle with a curved blade and having its right-angled terminalipivoted to one terminal of said dog, said blades having their convexed and concaved cutting edges respectively, efleetive to form a cutter as said lever I movable toward the dog and controlled in I0 is actuated. that direction by said step.

4. A device of the character described, a- In testimony whereof I have signed my comprising an S-shaped dog having intername to this specification in the presence of medlately of its terminals an outstanding lug two subscribing witnesses.

provided With an adjustable lateral stop, and I JOHN B. ADAMS, JR. a lever having a right-angled terminal pivot- Witnesses: ed to one terminal of said dog and equipped GEORGE ADAMs,

with a wire-securing clasp, said lever being JOHN WATERS.
