1'0 a/Z whom it may concern:

Be it known that we, CHARLES M. LAMB, residing at Monesson, inv the county of Westmoreland, State of Pennsylvania, and JAMES W. SNEDEKER, residing at Adrian, in the county of Lenawee, State of Michigan, citizens of the United States, have jointly inl vented certain new and useful Improvements in Eye-Forming Machines; and wedo declare Io the following to be a full, clear, and exact description of the invention, such as will enable .others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and

to the Iigures marked thereon, which form a part of 'this specification.

This invention relates to an eye-forming machine more especially adapted for turning an eye in the end of the horizontal wires of a 2o wire fence or of a single wire strand for the purpose of enabling said wires to be attached to a terminal support or to be joined together end to end when additional length is desired. The object of the invention is to provide 2 5 simple and efticientmeans for forming an eye upon the ends of the horizontal wires in fences and other structures or of single wire strands to be used for any purpose whatsoever by so twisting the crossed strands upon and about 3o each other as to prevent the twisted union or connection so formed from untwisting when the eye is subjected to great strains, such as results from Stringing a` section of fence or a single wire at high tension between fixed points. The above object is attained by the mechanism illustrated in the accompanying drawings, in which- Figure l is a plan view of our improved 4o machine. Fig. 2 is a side elevation, the supporting-standard being removed. Fig. 3 is a plan view of the machine, showing the position of the traveling head at the end of the twist and illustrating Yone of the twisted strands wrapped around the other strand, which is straight at that point. Fig. 4 is a perspective view showing the machine as at work upon the horizontal wires of a bundle of wire fencing. Fig. 5 is an enlarged vertical scction through the uppervend of the standard, showing the gear-wheels mounted thereon, the crank for operating said gearwheels, and the rotary bracket which su pports the slideway upon which the head is adapted to slide, parts being broken away. Fig. 6 is an. inverted plan of the movable carrier in which said head is pivoted and the arm which Shifts said head and is mounted upon the pivot-pin thereof. Fig; 7 is a 'transverse section through said head and carrier, the arm,

and the slideway in which the carrier is adapted to traveh- Referring to the characters of reference, l designates a vertical standard having journaled in the upper end thereof a shaft 2, carrying at one end a crank 3 and at the other end, which'projects through said standard, a pinion 4. Said pinion meshes with a gear-wheel 5, journaled upon a shaft 6, that extends into the standard l and is secured therein against rotation by set-screw 7, thatjirmly locks said shaft in place. Also j ournaled upon shaft 6 is a block 8, which is irmly attached to the gearwheel 5 and rotates therewith. Secured to the block 8 by thebolts 9 is a bracket l0, carrying at its outer end the horizontal slideway ll, having raised sides providedwith undercut edges 12, (see Fig. 7,) which receive the projecting beveled margins 13 13a of the slidable carrier lei, which is adaptedto reciprocate on said slideway.`v Mounted upon the Acarrier is a triangular head l5, in which is fixed a pin 16, that is journaled in said carrier and passes therethrough, its lower end havingr iixed thereon a reeiprocatory arm 17. In the projection endof said arm is a pin 18, on which is journaled an antifriction-roller 19, adapted to travel in a channel 20, extending longitudinally of the bed-plate 21Nof said slideway. The outer end of said channel is deliected sharply to one side, as shown at 22,'

for purposes hereinafter stated.

The shaft 6, which projects through the block 8 and upon which said block and the gear-wheel 5 are journaled, is provided at its outer end with a hook 23. The ends of the sel lateral wires 24, which project from the bundle of wire fencing 25, (illustrated in Fig. 4,) are formed in a loop 26, the free end 27 of the looped portion lying across the strand that leads to the bundle. In forming the eye the loop is placed upon the hook 23 of the shaft v, with the strand 24 lying in the channel 28,

formed in the upper face of the triangular head 15, along` one margin thereof, and the crossed end 27 lying in the undercut channel 29, formed in the opposite edge of said triangular head, which position of partsv is illustrated in Fig. 1. By means of the crank 3 the slideway ll is then rotated about a center of which the shaft 6 is the axis. The head 15 being in horizontal alinement with the axis of rotation causes the strands of wire which are held in the channels therein to twist together, as shown in Fig. 3. As said strands are twisted together said head is gradually forced rearwardly on the slideway 11, the carrier 14, upon which said head is pivoted, trav.- eling straight along said slideway, with the antifriction-roller 19 of said arm 17 traveling in the channel 2O in the bed of said slideway. During the initial twisting of said strands the head- 15 is revolved with its geometric center in line with the axis of rotation, so that the twisting of said strands are equal, as shown at 30. As the carrier slides rearwardly in the operation of twisting the strands the antifriction-roller 19 upon the rearwardlyprojecting arm 17 encounters the deflected portion 22 of the channel of the slideway and swings said arm to one side, thereby turning the head 15, so as to bring the channel 28 in line with the shaft 6 and cause the channel 29 to stand at a tangent thereto, whereby the strand 24 is left straight, as at 31, and the strand 27 is wrapped one or more times around the strand 24, as shown at 32, until the end thereof slips from the overhanging channel29 in the rotary head, whereby the strand 27 becomes firmly wrapped around the strand 24 in the manner to prevent a possible unwinding thereof by any strain that may be placed upon the eye formed of the loop 26 through the twisting of said strands.

After the formation of the eye above described the head 15 is moved forward upon the slideway to the initial position (shown in Fig. 1) and the operation repeated.

The direction of rotation of the head is such as to always confine the strand 24in the channel 28 therein, while the overhanging edge of the channel` 29 prevents 'the escape of the strand 27 therefrom. As the head is moved forward after the forming of an eye the antifriction-roller passinginto the straight portion of the channel 20 swings said head to the normal position, as will be understood.

It will now be apparent that by means of this improved machine an eye may be quickly formed in the projecting ends of the horizontal wires of a section of fence 0r in the ends of wires to be used for other purposes in a manner to so unite the crossed strands as to prevent them from nntwisting through any tensile strain which may be applied thereto, enabling the wires to be quickly and permanently attached to a terminal post or other object or to another similar wire when two or more are to be joined end to end.

The standard 1 is supported upon a platform 33, mounted upon suitable casters 34, so as to render it transportable, said platform also carrying a seat 35 for the operator. This arrangement renders the machine portable and enables it to be moved from bundle to bundle of fencing in the operation of turning an eye on the ends of the horizontal wires thereof or from place to place for any purpose desired.

I n order to provide su fcient friction to prevent the head from sliding too freely upon the slideway, the beveled margin or strip 13:L of the carrier 14 is pivoted at one end to the carrier by the pin 36, while the other end is forced away from its companion part 13 by the coiled spring 37, which is interposed between them and whose tension is normally exerted to force the pivoted margin or strip outwardly, as shown by dotted lines in Fig. 6. This action of the spring causes the beveled margin of the carrier to bind in the slideway, thereby resisting the tendency of the wire. strands to force the head outwardly as they are twisted together, whereby the wires are more 'closely twisted together and a more satisfactory result is obtained.

Having thus fully set forth our invention,

what we claim as new, and desire to secure by Letters Patent, is-
