MACHINE FOR MAKING STAPLE-FENCING.

Specification of Letters Patent.

Patented Aug. 1, 1905.

Application filed October 21, 1904:. Serial No. 229,362.

To all whom it may concern.-

Be it known that I, SHERMAN S. WITHING- TON, a citizen of the United States, residing at Adrian, in the county of Len'awee, State of Michigan, have invented certain new and usevful Improvements in Machines for Making Staple-Fencing; and I do declare the following to be a full, clear, and exact des'cription 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 figures of reference'marked thereon, which form a part of this specification.

This invention relates to machines for making wire fencing of the type known as staplefencing,v wherein the crossed wires are united at their junction by tying-staples; and it consists inthe construction and arrangement of parts hereinafter fully set forth, and pointed out particularly in the claims.

The object ofthe invention is to produce a machine of the characterdescribed wherein the arrangement is such as to support and carry the reciprocatory cross -beam, upon which are mounted the movable parts of the dies between which the crossed strands of the fencing are joined by the tying-staples, so that said cross-beam may be actuated to bring the parts of the dies into working relation and to separate them without imparting undue shock or vibration to the machine, enabling the machine to be run at a higher rate of speed and increasing 1ts capacity in a corre-' sponding degree.

The above object is attained by the structure illustrated in the accompanying drawings, in

which- Figure 1 is an elevation of a machine embodying my invention. Fig. 2 is a vertical transverse section as on line- 2 2 of Fig. 1, showing in section the crimping-drums omitted from Fig. 1 and between which the fabric passes after leaving the dies in which the crossed strands are joined, also showing in section the roller or drum upon which the completed fabric is wound, also omitted from Fig. 3 is a vertical transverse section as on line 3 3 of Fig. 1. Fig. 4: is an enlarged detail in vertical section through the rocker-arm and its bearing-support, as on line 4L 4 of Fig. 3.

said main shaft is a pinion 4, which meshes with the gear-wheel 5 on the stub-shaft 6,

journaled in the frame at one end and sup ported at the other end by the bracket 7.

Also fixed to the shaft 6 is a pinion 8, which meshes with a large gear-wheel 9 upon the end of shaft 10, extending longitudinally of and journaled in the upper portion of the frame of the machine. By means of the train of gears just described, through the medium of which the shaft 10 is driven, the speed of said shaft is reduced and sufficient power furnished for the purposes required. Fixed to the shaft 10, near each endthereof, are the eccentrics 11, the straps 12 of which are connected with the short eccentric-rods 13, whose lower ends are pivotally attached at 15 to the opposite ends of the cross-head 16, adapted to reciprocate vertically in the frame and carrying the driving-plungers 17, adapted to enter the closed dies to drive the tying-staples around the crossed strands embraced between them, as will be well understood in the art.

The reciprocatory beam 18, which carries the movable dies 19, as shown in Fig. 2, is supported at its ends in the inclined ways 20 in the sides of the frame and is actuated through the medium of the toggle-levers 21,

which are pivoted at one end to the ends of lower ends and at their upper ends are pivoted,

as at 26, to one end of the rocker-arms 27 which are journaled upon the pins 28, supported in the frame and in the brackets 29,

the opposite ends of said arms carrying the antifriction-rollers 30. (More clearly shown in Fig. 3.) Fixed to the main shaft 10 adjacent the eccentrics 11 are the cam-disks 31, which are adapted to roll in contact with the antifrietion-roller 30 on the rocker-arms 27. The tendency of the beam 18 is to slide downwardly in the inclined ways 20, so that the weight of said ,beam is at all times carried on the rocker arms, whereby the antifriction rollers 30 are maintained in continuous contact with said cam disks. When the rotation of the shaft 10 brings the lower sides 32 of the cam-disks 31 into engagement with the antifriction-rollers of the rocker-arms, as shown by solid lines in Fig. 3, the togglelevers 21 would be in a position to allow the beam 18 to slide away from the fixed beam 33, to which the fixed dies 34 are attached, permitting freedom of movement of the fabric upwardly through the machine between said dies. As a further rotation of the shaft 10 causes the high sides 35 of said cams to ride onto the antifriction-rollers of the rockerarms, said arms are actuated to raise the connectin'g-rods 24 and operate the toggle-levers to close the dies or bring them together upon the crossed strands of the fabric, as shown by dotted lines in Fig. 3, in which position the dies remain while said cam-disks are traveling the distance of the concentric portions of their arcs, during which time the operation of driving the tying-staples is accomplished. When the high sides of said cam-disks pass from engagement with the antifriction-rollers of the rockerarms and the eccentric sides of said disks engage said rollers, the beam 18is allowed to again slide away from the beam 33 to open the dies and to permit the passage of the fabric upwardly therethrough, as before described. It will therefore be evident that the beam 18 is at all times carried by the rocker-arms, whose antifrietion-rollers travel in peripheral contact with the cam-disks 31, whereby the reciprocatory movement imparted to the beam 18 is made gradual with respect to the termination of movement in one direction and the inception of movement in the opposite direction, preventing all jerking and jarring incident to the sudden starting and sudden arresting of a heavy body and yet imparting a rapid movement to the beam between the terminals of its reciprocatory movement, thereby enabling the machine to be run at a comparatively high rate of speed. It will also be evident that through the medium of the toggle-levers a very high degree of leverage is attained at the moment the working faces of the dies are brought together, owing to the fact that said levers will then occupy nearly a straight line between their centersa position in which said parts are maintained during the time the cam-disks are traveling with their high sides in engagement 42, which in turn'meshes with the gear 43 on the shaft of the drum 41. The tying-staples 44 are shown upon the inclines 45 and are adapted to be fed into the dies by the notched feeding-wheels 46, as shown in Fig. 2, so as to be engaged by the plungers 17 and driven into the closed dies to unite the longitudinal and the transverse strands, the latter being shown at 47 in Fig. 2.

Having thus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent. is
