CRIMPING MECHANISM. FOR WIRE-FENCE MACHINES.

Specification of Beissued Letters Patent. Beissued May 28, 1907.

To all whom it may concernl:

Be it known that 1, JOHN A. COOKER, of Joliet, Will count Illinois, have invented a new and useful improvement in Crimpi Mechanism for Wire-Fence Machines, (5 which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figurel is a side elevation of that ortion of awire-fencemachine which embo ies my improvement. Fig. 2.is a section on the line 11-11 of Fig. 1. F i 3 is a section on the irregular line IIIII of 4; and is a view, partly broken away, showjn the lower portion of the crimping roll or m and the actuatin mecham'sm for the'crim ing-bars, one-ha of the view being in si e elevation and the other-half in vertical section.

My invention has relation to means for formin crimps or corrugations in the longitudinaFwires of wire fencing or woven-wire fabric, and is designed to provide means of novel and effective character for actuating ing members or bars, which will operate wit less friction and with less wear and tear than the means which have commonly been employed heretofore.

My invention is a plicable to various forms of woven-wire mac es, being independent which are employed for forming the fabric.

In the accompanying drawings the numerals 2 and 3 designate the guide-rolls of a wirefence machine of any suitable character in which the fabric (indicated by the dotted 5 designates a combined pull out and crimping drum, over whichthe formed fabric 4 passes on its way to the win s 001 ordrlim 6.. The drum 5 is providedmt aplurality ,of longitudinally-movable crimdping-ba'rs 7,-

which are seated between fixe bars 8, secured in the peripheral portion of'the drum and projecting t erefrom. The bar's7 are formed with a series of notches 9 to receive the I longitudinal wires or strands of the fabric .4,

the fixed bars 8- are formed-with correspondingenotches 10. The bars '7,project at one end yond the endof the drum 5 and'areengaged in recesses 1 I of a rotary member or ring 12, which is arranged to revolveupon substantially as described.

fixed base V The base 13 is preferably rovided with a hub portion 14, around w ich the ring 12 is mounted with a series of intersed antifriction rollers 15. The upper ace of the base 13 aroundthe hub portion 14 is an inclined plane, while the axis of the drum '5 is perpendicular to the base-line of the machine. The drum 5 is revolved in any suitable manner, as by the caring l6 and 17, from a driven shaft 18, and by reason of the engagement with the ring 12 of the movable crimping-bar 7 said ring .is rotated with the drum, its plane of rotation being inclined as described. The series of antifriction-rollers 15 have a similar inclination, as shown in Fig. 4. By reason of this inclination the up er surface of the ring is about one-half inc closer to the drum at one side than it is' at the o posite side, and as the ring is revolved tile movable crim ing-bars 7 are dur i one-half of a revolution gradually raised or ifted, thereby grip ing and crimping the strand-wires of the fai fric 4 and also stretching the wire between the different sets of bars.

During the other half-revolution the crimp- 1 -bars move downwardly by gravity or by 0t er suitable positive means (not shown), and successively release the Wires. v

The ends of the bars 7 which engage the recesses 11 are provided with suflicient play or clearance tlgrein to permit them to move as the drum'rotates to maintain the perpendicular osition of the bars,

-I pre erably mount the ring 12 upon ballbearings 19.

The advantages of my invention consist in the simplicity of the construction and arrangement and in the fact that its operation takes place with very little friction or wear and tear of the parts.

Various changes may bemade in the details of construction and arrangement by those skilled in the art without departing from the spirit and scope of my invention,

since WhatIclaim is k v 1. In a wire-crimping device, a rotatable drum, a lo 'tudinally-movable crimpingbar mounte therein, and a rotary member 'is inclined to the axis of the drum;

2. A wire gripping and crimping device,

aging the bar and rotating in a plane' comprising a rotary drum, a plurality of endwise-movable crimping-bars carried thereby, and a rotary member jonrnaled to rotate in a plane inclined to the axis of the drum and engaging the crimping-bars substantially as described.

3 In a wire grippin and crimping device, a rotary drum havin iced in its periphery a pluralit of notched ars arranged in pairs, a series 0 longitudinally-movablebars having corresponding notches and arranged one between each pair of the fixed bars, and an actuating device for the movablev bars consisting of a rotary member in which the lower ends of the bars are seated, and which is journaled to rotate in a plane inclined to the axis of the drum; substantially as described.

4. In a wire gripping and crimping device, the combination with a drum havi a plurality of endwise-movable crimpingars, of

a rotary member journaled to rotate in a plane inclined to the axis of the drum and engaging the said bars; substantially as described.

5. In a wire gripping and crimping device, the combination with'a drum having a pinrality of endwise movable gripping and crimping bars, of a fixed base having an upper surface inclined to the axis of the drum, and a ring journaled upon said base to rotate in a plane parallel Wltll such surface, said ring havin recesses which engage the end portions 0 said bars; substantially as described.

In testimony whereof I have hereunto set my hand this first day of March, 1907.
