A prototype part drawing/flanging tool is provided that are arranged in a draw die set-up and a flange die set-up. The draw die set-up includes a binder ring, a pad; a flange forming ring, and a punch. The flange die set-up includes the flanging ring, the pad, and the punch. The draw die set draws a blank and the flange die set forms a flange on the blank in two separate operations using the same die parts in the two operations. A method is disclosed for making a formed and flanged part that begins by drawing a blank held by a pad, a flanging ring and a binder ring against a punch in a press to form a drawn blank. The drawn blank is then laser trimmed to form a trimmed/drawn blank. The trimmed/drawn blank is then clamped between the pad and the punch while the flange forming ring forms a flange into a flange forming groove.

An improved chair for supporting intersecting wires forming a wire mesh at a pre-selected elevated position above a bearing surface during formation of a concrete slab is constructed having a base member shaped to rest on the bearing surface, a compressible support structure having a lower section affixed to the base member, a middle section and an upper section affixed to a setting shaped to support the wire mess at the elevated position. The chair is constructed having an improved compressible, generally bell-shape support structure having two pairs of opposing arched-shaped openings in the middle section forming two intersecting arches, each arch having a pair of opposing flexible legs that bow outward when a pre-determined load is applied to the upper section. The support structure further having a strengthening plate affixed on an interior surface of the upper section of the support structure formed by the intersecting arches, the chair being constructed from a blend of high density and low density crystalline polymer.

Chair for supporting wire mesh

Reinforcing wire mesh support

A chair for supporting, positioning and retaining a concrete reinforcing bar in place at predetermined height in the pouring and construction of concrete slabs or beams at a jobsite wherein the concrete reinforcing bar remains as an integral, strengthening element of the construction. The chair includes a cap with a recessed or slotted upper face for retaining and supporting the concrete reinforcing bar, and a base; the cap (which supports the concrete reinforcing bar) being supported above the base via a stem. Caps and bases of standard size can be supplied to a jobsite, and chairs of varying height readily constructed therefrom at the jobsite by cutting stems of desired length from a concrete reinforcing rod, based on the requirements of slab thickness, or beam depth.

Chairs of adjustable height for use in concrete constructions

A peripherally continuous frame is provided for receiving the open mouth of a bag therethrough with the free edge portions of the bag mouth folded outwardly and back over the outer surfaces of the frame. Peripherally spaced portions of the frame each have one end portion of an elongated arm member pivotally anchored thereto for oscillation about an axis transverse to the arm member and the corresponding frame portion and generally paralleling the medial plane of the frame. The free end portion of each arm member includes an elongated longitudinally extending clamp portion thereof which is generally U-shaped in transverse cross section, opens laterally outwardly of the arm member and includes open opposite ends. The clamp portions are swingable into and out of positions with an adjacent frame portion embracingly received therein and extending longitudinally therealong, whereby when the free edge portion of a bag is folded outwardly and back over the adjacent frame portions they may be releasably clamped to the frame portions by the U-shaped free end portions of the arm members. The frame includes an elongated outwardly projecting handle supported from one marginal portion thereof.

Bag mouth holder

A hinge for mounting a door to a door jamb in hinged relationship in a construction wherein the door and door jamb are formed from a longitudinally grooved frame wherein the elements forming the hinge can be fitted within the accommodating longitudinal grooves of said frame to provide the hinged relationship. Both of the hinge elements and frame are cut from longer lengths of extrudate metal stock. The hinge segments are of corresponding cross-section, each including tubular portions which can be fitted together in tandem and pivotally attached or pinned one segment to another, and key portions constituting male members capable of mating with accommodating female slots located in the frame to provide the hinged relationship between the door and door jamb.
