1. A wire bending device comprising: a frame; a first wire guide mounted on said frame; a movable second wire guide; programmable guide moving means mounted on said frame and operable to move said second wire guide relative to said first wire guide in a selected sequence of movements; wire feeding means operable to feed wire by said first and second wire guides; means for simultaneously operating said guide moving means and said wire feeding means; said programmable means including a single programming wheel rotatably mounted on said frame, a plurality of elements and means for selectively mounting said elements on said wheel at selected radial positions thereon to rotate with it, and an arm, having said movable guide thereon, movably mounted on said frame and resiliently urged against elements on said wheel so that motion of said arm is governed solely by said elements.

3. A wire bending device including: a frame; first and second wheels rotatably mounted on said frame, with their rims adjacent to each other to feed wire between them; means for holding a spool of wire on said frame, so that wire therefrom can feed between said wheels; a first guide mounted on said frame for directing wire that has passed between said wheels; an arm pivotally mounted on said frame; a second guide mounted on said arm to move relative to said first guide in accordance with movements of said arm; and means for engaging said arm to determine its position, said means for engaging said arm including a plurality of apertures in said first wheel for holding pins that can abut said arm, and Spring means for urging said arm against pins in said apertures.

4. A wire bending device including: a frame; first and second wheels rotatably mounted on said frame, with their rims adjacent to each other to feed wire between them; means for holding a spool of wire on said frame, so that wire therefrom can feed between said wheels; a first guide mounted on said frame for directing wire that has passed between said wheels; an arm pivotally mounted on said frame; a second guide mounted on said arm to move relative to said first guide in accordance with movements of said arm; and means for engaging said arm to determine its position, a handle on said second wheel for enabling manual rotation of said second wheel; and gear means mounted on said first and second wheels for positively rotating said first wheel when said handle is turned.

5. A wire bending device including: a frame; first and second wheels rotatably mounted on said frame, with their rims adjacent to each other to feed wire between them; means for holding a spool of wire on said frame, so that wire therefrom can feed between said wheels; a first guide mounted on said frame for directing wire that has passed between said wheels; an arm pivotally mounted on said frame; a second guide mounted on said arm to move relative to said first guide in accordance with movements of said arm; and means for engaging said arm to determine its position, said frame having a handle portion for holding in the hand to support the frame in a predetermined orientation wherein the axes of rotation of said wheels are substantially vertical; said first guide feeding wire in a substantially horizontal direction from said wheels; and said arm being mounted to pivot about a substantially vertical axis, so that said second guide thereon bends wire about a substantially vertical axis.
