Abstract
Abstract An apparatus for use in the manufacture of wire screening or mesh which determines the pitch thereof. The apparatus incorporates a means for drawing the completed wire screen or mesh through a welding apparatus. A plurality of flexible chain drives incorporates upwardly extending dogs which selectively engage the wire mesh and the transverse members thereof. The dogs are movable so as to adjust to a different pitch. The chain drives are advanced by means of a ratchet mechanism, the stroke thereof being variable. The stroke can be varied, for example, from two inches to about six inches.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
86 words
A fence or wire mesh handling apparatus which comprises: a supportive framework; an upper surface on said framework; a plurality of flexible drive members arranged in parallel fashion adjacent to said surface; a plurality of lugs carried on said flexible drive members and adapted to engage a fencing material; a motive means for advancing in unison said plurality of flexible drive members to draw such a fencing material on engagement with said lugs; and, means for adjusting the spacing of said lugs on said drive members.
Claim 2
Dependent Claim
86 words
A fence or wire mesh handling apparatus which comprises: a supportive framework; an upper surface on said framework; a plurality of flexible drive members arranged in parallel fashion adjacent to said surface; a plurality of lugs carried on said flexible drive members and adapted to engage a fencing material; a motive means for advancing in unison said plurality of flexible drive members to draw such a fencing material on engagement with said lugs; and, means for adjusting the spacing of said lugs on said drive members.
Claim 3
Dependent Claim
33 words
The invention of claim 1 wherein said motive means includes a unidirectional ratchet mechanism wherein the length of step of said ratchet mechanism is altered dependent on the pitch of the fencing material.
Claim 4
Dependent Claim
52 words
The invention of claim 2 wherein said motive means incorporates a gear having teeth therein; lock means for engaging the teeth of said gear to limit its rotation to a single direction; advancing means engaged with said gear for advancing said gear periodically, said advancing means having a predetermined length of advance.
Claim 5
Dependent Claim
62 words
The invention of claim 3 wherein said advancing means incorporates a bell crank mounted on a common axis with said gear and driven by an extensible member, said bell crank including a push rod which is connected therefrom to said gear for engaging the teeth thereof and forcing said gear to advance by a length of stroke determined by said advancing means.
Claim 6
Dependent Claim
23 words
The invention of claim 4 wherein said gear has teeth of a predetermIned spacing and further including means for altering the spacing thereof.
Claim 7
Dependent Claim
36 words
The invention of claim 3 wherein said gear incorporates teeth having a fixed spacing, and further including a means for attaching additional teeth to said gear at a spacing which is less than the original spacing.
Claim 8
Dependent Claim
22 words
The invention of claim 1 wherein said flexible drive members are endless loop members and extend above said surface and loop therebelow.
Claim 9
Dependent Claim
33 words
The invention of claim 1 wherein said drive members carry said lugs with regular spacing along the length thereof and lugs on adjacent drive members are evenly arranged with respect to one another.
Claim 10
Dependent Claim
39 words
The invention of claim 1 including first, second and third shaft members parallel to one another and wherein said flexible drive members are endless loops about said shafts, and one of said shafts is rotated by said motive means.
Claim 11
Dependent Claim
22 words
The invention of claim 9 wherein said first and second shafts engage and position said drive members to extend across said surface.
Claim 12
Dependent Claim
55 words
The invention of claim 10 wherein said third shaft is below the level of said surface at a location such that said flexible drive members engage said lugs with the fencing material between said first and second shafts and said lugs are withdrawn from engagement with the fencing material between said second and third shafts.
Claim 13
Dependent Claim
15 words
The invention of claim 11 wherein said third shaft is rotated by said motive means.
