HARTEnQoF wAoxEeAn, ILLINOISi- The invention relates to fence making machinery and has reference more particularly to improvements in mechanism for forming versely and longitudinally of the fabric which are substantially equal, but under conditions in actual use, the fabric. will. be stretched so that the longitudinal axes in crease in length and the: transverse axesicorwire fence is therefore unsuited for use under conditions where severe strain will he placed uponit. The present invention contemplates a novel form ofwire fence picket which, when fabricate'd into fencing will form a fabric'of triangular mesh. This type of mesh consists of diagonal portions joined by substantial horizontal portions, whereby longitudinal strain placed upon the fabricwill be taken up by horizontal portions, and thus tendency to elongate in directions parallel: to

these portions will be materially reduced. To this end an object of the present invention is to provide ways and means of forming a wire fence picket of the novel type described, and of performing similar wire bending operations. i t

A still further object of the invention is to provide novel fence making machinery which will be simple in construction and positive and reliable in operation. v v

Referring to the drawings, particularly 'to L Figure 3, the present mechanism is shown as including a plurality ofv base members 10 supportinga plurality. of vise members 11 byuneans of securing bolts 12. ,The vise g0 respondingly reduce in length. This type ofmembers areadapted to hold in rigid posi-i tion a spiral member designated inits entirety by 14. Located within the spiralisi j an arbor 15, which is adapted to have rotation within the spiral and for-this purpose has its right hand end, asviewed in Figure 1, located in slot 16. rovided in the: driving shaft QAny suita leofpower may I be associated with the driving shaft toim+ r1 part rotary movement thereto.

Associated with these spiral threads is a of which will be presently described;

, A continuous length of wire 23 is fed to t the arbor (15, the wire beingi first passed through a seriesofstraightening:rolls. 24, located on a base 25.: In the operationof the mechanism as rotations are;imparte d tothe shaft. 17, the -,-wire strand: 23; is fed: to

is provided with a cam race 27. A cross shaft 28 mounted in bearings 29 is provided I with an upstanding arm 30 having a pin 31 adapted toride within the cam race 27. The arm 32 located on thezother end of thecross shaft 28 is provided at its upper end with '1 a pin'33, whichhas connection with the leverf 344, the leveriin' turn being pivotally secured at 35 to arm 36." The arm 36 is rotatably mounted on pin 37 which pin is securedto base 38 formed integrally with one of the vise members 11. On the outer end of arm 36 is located a depending pin 10 adapted to have contacting engagement with the wire strand 23 immediately prior to the feeding 'of'the same to the arbor 15. As

previously stated thelocationof the feed of thewi're strand to the arbor'is changed once an every revolution of the arbor, which is accomplishedby the depending pin 4O through'oscillating movements imparted to p the arm 36. The timing of these movements and-thus the variations in the location of the feed of thewirestrand tothe arbor is con- 'trolledby the specific formation given to the 'cam race27. i

"It is to be noted that the width of the f *arbor 15 determines the length'ofc the horizontal portions formed in the wire picket,

3 wirepic'ket by reason of the thickness of the arbor.wAl'so, as' :will be more fully exwhile a certain thickness is: imparted to the plained,-the diagonal portions of the picket whlch'serve 'to' connect thehorizontal por tions'is'accomplished by the variation in the location of the point at which the wire strand is fed to the arbor. 7

In order to more fully understand the novel features of the present invention, attention -is'"directed to Figures 7 and 8 of the drawings, which showthe-characteristic shape of the Wire picket formed by the present "mechanism. -The horizontal -portions6 are' connected' by bends 7 to diagonal portions 8 which serveto form a triangular shaped mesh when thevarious pickets are interlinked" wlth thelr adjacent pickets. ,Bythe mecha nism-de'scribed, the portions 6 maybe formed horizontally,as shown in Figure I 8,or may have a slight displacement from the horizon-V tal' as more particularly shown in Figure 7. In the operation of the device, reference or I 69;

being had to Figures 4, 5 and 6, the arborv 15 is shown in avertical position and adapted to have rotation in a direction as indicated 1' by marrow; The pin 40, although, having contacting 'engagementwith the wire strand '1 "23 is at-this particular position of the arbor locatediinf its extreme left hand position. Wlth the parts inthis position, it will be noted that one of the bends 7-between the horizontal and diagonal portions is just being completed. Referring more particularly p to Figure 5, it will be seen that the arbor 15 has been rotated 90 from its position 1n Figure 41 and is now located in a substantlally horizontal position. Also, the pin is stlll 7 located in its extreme left hand position, but 7 it will be seen that by reasonof the rotation of the arbor 15, the spiral member remaining stationary, the wire picket has moved a distance on the arbor equal. to one quarteri of the pitch of the spiral member 21, namely from 7 point a to point I). It. is during the next 90 movement of the arbor that movementis imparted to the pin 40,; which thus locates the'pin adjacent the right hand end of the spiral 21 at point 0. This effects a material change in. the position at which the wire v strand 23 is fed'to the arbor 15 and thus causes 7 the formation on the wire picket of the diag- "onal portion 8. The magnitude of this diagonal portion is determinedjby the change in location of the feed of the wire strand 23 to V V the arbor 15, causedby movement oi the pin 40in addition to the movementof the picket itself upon the arbor due torotation of the arbor which will equal. substantially one or the distancefrom point'b'todg I i quarter of the pitchof' the spiral member,

' Upon'continued rotation of the arbor15, the bend 7 being formed in -thei picketas shown in Figure 6, will have move'd. from the point-c to point e during which movement of thearbor the pin 40-is retracted so that the combined efi'ect of the movement of the movement imparted to. the 'pin 40 will form onthe'picketthe-horizontalportion Duriing the-next movement of the arbor another of the bends 7: inzth'e picket is formed 7 whereupon theiparts'will assume the same position as disclosed in Figure 4 and the series of operations will be again repeated. It is to be noted that the horizontalportionsfi of ment of the pin the picket-is also being caused to move in a: left hand 1 direction r upon I the arbor 15 by reason of thezengagement of the bends 7 which have been formed 'iwith the tion: in the timing of themovement imparted picket on the arb0r15 -and the rearward the picket are formed as thepin :40 isbei'ng retracted, but in combination with this 'movethreads of the spiralmember'21. By a varia to'thefpin 40, the, portions 6 on the; picket may be given a slight angular displacement from the true horizontahwhich' will result Figure 7. I

Although in the formation of a picket asidisclosed in the operation of the 'mechanism J has been describedlin connection with figures showing only-skeleton-parts of the. machine,

the operationof the complete device asshown in Figure 1 issimilar exceptthat the spiral member employed presents spiral openings 22 within which is located the .vari'ous bends thus pin is caused by the contour of the f cam race 27. Thepdisk 26 and arbor 15'are both associated with shaft 17 which results in a complete cycle of movement being imparted to arm 36 during every revolution of the arbor. There is formed upon the arbor then for every revolution a horizontal por tion 6, a bend 7 and a diagonal portion 8. It was previously stated that for a slight displacement of the horizontal portion it was only necessary to vary the timing in the movements imparted to the arm"36. This can accordingly be accomplished by replacing the disk 26 by a similar disk having a cam race of a slightly different contour It is to be understoodthat I do not wish to be limited by the exact embodiment of the device shown, which is merely by way of illustration. and not limitation, as various and other forms of the device will of course be apparent to those skilled in the art without departing from the spirit of the invention or the scope of the claims.
