CRIIVIPING MECHANISM FOR WIRE-FENCE MACHINES.

Specification of Letters Patent.

Patented Feb. 27, 1906.

Application filed August 17,1904. Renewed August 1'7, 1905. Serial No. 274,646.

To aZZ whom it may concern.-

Be it known that we, WASHINGTON M. DIL- LON and PETER FRANTZ, citizens of the United States, residing at Sterling, in the county of I/Vhiteside and State of Illinois, have invented certain new and useful Improvements in Crimping Mechanism for WVire-Fence Ma chines; and we do declare 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 characters of reference marked thereon, which form a part of this specification.

Our invention has reference to crimping mechanism for wire-fence machines, and is specially designed to assist in producing the style of fence shown and described in Letters Patent of the -United States No. 755,637, issued March 29, 1904, to W. M. Dillon.

In the present application our invention is shown as substituted for the crimping devices illustrated and set forth in Letters Patent of the United States No. 739,846, issued Sep tember 29, 1903, to P. Frantz; but by changes in the structure and arrangement of the parts the same can be adapted to be used in other machines which produce a square-mesh fence. In the following specification only those parts of the old machine will be referred to which are pertinent to the operation of the crimping mechanism.

In the drawings, Figure 1 is a plan view of a machine embodying our invention with some of the parts removed. Fig. 2 is a side elevation of the rear portion of the machine, showing parts of our invention in end view. Fig. 3 is a vertical section in the line 3 3 of Fig. 1. Fig. 4 shows parts of the operating mechanism of our invention in detail. Fig. 5 is an enlarged detail of parts thereof in plan view. Fig. 6 is a detail of one of the dies 18 in elevation. Fig. 7 is a plan view of our device in detail.

Similar characters refer to similar parts throughout the several views.

1. 1 represent the frame of the machine, united at each end by

cross-plates

2 and 3. J ournaled on the under side of the frame 1 is a main shaft 4, at one end of which the power is applied in any usual method to operate the machine. On the opposite end of the shaft 4 is a gear-pinion 5, actuating a gear-wheel 6 on the end of a rotaryshaft 7, supported beneath the frame 1, parallel with the shaft 4.

8 8 represent a series of strand-wires in their progress through the machine, and 9 9 transverse wires, having their ends coiled upon the strand-wires at regular intervals to form the fence. The wires 8 are suitably drawn through the machine with an inter mittent or step-by-step movement. I

Pivotally secured to the cross-plate 2, as at a, Fig. 3, is a pair of levers 10, provided at their free ends with rollers 11, which engage the faces of a pair of cam-wheels 12, fixed on the shaft 7, such levers being supported at their free ends by the earns 12. Having virtical movement in ways 13 on the inner faces of the frame is a cross-bar 14, such bar being supported on the levers by means of sli'de blocks 15 on the lower face of such bar. A channel 16 extends longitudinally of the bar 14, supported in such channel being a slide-bar 17, so as to be capable of reciprocating movement therein transversely of the machine. Fixed on the bar 14 is a series of dies 18, and. on the bar 17 is secured a series of dies 19, corresponding in number with the dies 18 and adapted to be brought simultaneously into proximity with said last-named dies upon the bar 17 being suitably operated. Fulcrumed in the channel 16 beneath the bar 17 is a bell-crank lever 20, having its upper arm secured to the slide-bar 17 by means of a link 21. Fixed on the shaft 7 is a cam 22, having a track 23, engaged by a follower 24, projecting from the lower arm of the lever 20. By this means each rotation of the shaft 7 operates to reciprocate the bar 17 and bring the dies 19 into proximity with the dies 18.

Transversely of the die 18 is a \I-shaped channel 25, and the die 19 is similarly provided with a channel 26. The dies 18 and 19 are so disposed upon the

bars

14 and 17, respectively, that the space between each pair thereof is just below one of the strand-wires 8, and in the crimping operation said wires are embraced between the several pairs of dies, the wires 9 being accommodated by the channels and. 26. IWhen in this position, the coils of each adj accnt pair of stay-wires are held from lateral movement by ribs 27 and 28 on the inner faces of the dies 18 and 19, respectively, the strand-wire being bent or crimped on one side of the coils by a jaw 29 on the die 18 and on the other side of the coils by a similar jaw 30 on the die 19. The strand-wire is further h eld while b eing crimped by vertical ribs 31 and 32 on the dies 18 and 19, respectively.

Secured at each side on the frame 1 is a pair of supports 33, in the upper ends of which is journaled a rock-shaft 34, fixed on which is a pair of levers 35, having the ends of their long arms loosely connected with the levers 10 by means of the vertical rods 36. Depending from the short ends of the levers 35 is a pair of racks 37, supporting at their lower ends a pair of transverse parallel bars 38, which are normally held a short distance above the wires 8, so as not to interfere with the passage thereof. J ournaled in the supports 33 is a rockshaft 39, fixed on which is a series of short arms 40, having at their outer ends claws 41. The arrangement of the arms 40 is such that each of the strand-wires 8 is adapted to be embraced by one of the claws 41 upon the proper operation of thereof. To the end of the shaft 39 is secured an arm 42, provided with a roller 43, engaging the face of a cam-wheel 44 on one end of the shaft 7.

To recapitulate, the operation of the crimping mechanism is as follows: In the progress of the wires 8 through the machine and after the wires 9 have been secured thereon each intermittent movement of the strand-wires operates to bring a series of stay-wires immediately above the crimping-bar in position to be engaged by the dies thereon. By the rotation of the cams 12 at the proper time the levers 10 and bar 14 are raised until each of the wires 8 occupies one of the spaces between one pair of dies 18 and 19. The upward movement of the levers 10 rocks the levers 35, resulting in the downward movement of the racks 37 and bars 38 until such bars rest upon the wires 8 on each side of the bar 14 and prevent the accidental movement of the wires from between the dies. While in this position the bar 17 is reciprocated, bringing the dies 1.9 into close proximity with the dies 18 and forming the crimps in the strand-wires. In the forming of the crimp there is a tendency to force that part of the strand-wire adjacent thereto out of line, which tendency is overcome by the use of the ribs 31 and 32 on the inner faces of the dies. The rock-shaft 39 and claws 41 constitute an auxiliary device which may be used or not, as desired, the purpose thereof being to overcome any danger of the stay-wires getting out of alinement, so as not to properly enter the

channels

25 and 26 in the dies. When such parts are used, as the wires 8 near the end of a movement, the shaft 39 rocks sufficiently to cause the claws 41 to engage the wires 8 and hold any stay-wires which may be in advance of the other stay-wires until such other wires come in line therewith. As the bar 14 is raised the claws are again elevated, so as not to interfere with the dies thereon. After the crimps have been formed in the wires the dies again separate through the return movement of the bar 17, and the bar 14 is lowered to permit the further passage of the wires.
