The first leg includes a guide recess adjacent a second end and adapted to guidingly engage the raised portion on the first side of the wall.
Abstract: A process for manufacturing an aneurysm clip (10) having a coil spring (22), a first arm (26) ending in a first clamping jaw, and a second arm (34) ending in a second clamping jaw (40). The method includes: (a) providing a cylindrical starting rod (1) of titanium or titanium alloy; (b) cold drawing the rod to reduce its diameter and increase its strength; (c) cutting the rod to form a single resilient member (12); (d) winding the member about a mandrel to form the coil spring while incorporating the deflection of the arms into the clamping force of the clip; (e) shaping the member into two end sections (16) forming the clamping jaws and two connecting sections (18) forming connecting elements for the jaws; (f) coining the two end sections of the member a temperature between 900 and 1000 degrees F.; and (g) bending the clamping jaws into a position assuring that the clamping jaws are parallel when clamped onto tissue (70).
Abstract: A hog ring fastener has a straight line base and legs each perpendicular to the base but offset at an angle to each other permitting the use of relatively inexpensive "C" points. A stick of the fasteners is generally channel shaped, with the legs and bases all angularly inclined to the longitudinal axis of the stick. The assembly of fasteners is made in a multiwire process by severing blanks and forming the legs at a bias to a line perpendicular to the wire direction. A tool and method for applying the fastener carries out two different deformation stages, one being a predeformation stage to incline the legs of the fastener inward to a preferred application position.
Abstract: An apparatus used for the paper clip making machine downstream of the cutting machine comprises, a set of conveyors including continuous belt continuous chains, transferring wheels for advancing the cut wires, pieces of magnet properly located on the conveyors for attracting and arraying the cut wire in a proper orientation, three annular members spaced apart and mounted for rotation on the same axis, each of the annular members having a plurality of forming die member on the rim thereof for receiving and engaging cut wires, three segmented ring members of different lengths provided along the circumferences of corresponding annular members, ramming means provided at two sides of the annular member assembly adapted to exert bending forces on cut wires in the direction parallel to the axis of the annular member, the die members intermittently rising from the rim of the annular member to cooperate with the ramming means to bend the cut wires about the segmented ring members.
Abstract: An apparatus for making paper clips which includes cutting predetermined lengths of wire by advancing a continuous wire at a predetermined speed to a cutting station. The cutting station includes knife means with the knife having a cutting blade edge for penetrating the wire. Delivery means to engage the wire are provided along the path downstream of the cutting station for advancing the wire into a receiving slot. The receiving slot is provided with a deflecting member at an acute angle to the path of the wire and a magnet. The cut wire is then lifted out of the slot by an elevator platform means, and the wire is engaged by a ramming plate associated with three spindles, each spindle adapted to pass through a respective die member and the die member having spiral bending edges for bending the cut wire about the respective spindles for forming the paper clip.
Abstract: Clips adapted to be subsequently employed in tying the necks of bags and the like are formed in a continuous ribbon of metallic material and adapted to be wound on a reel for subsequent use as ties. A continuous ribbon of flat material is bent alternately in opposite directions at spaced points along its length to form a continuous length of generally sinusoidal-shaped similar connected elements so that substantially all of the deformation of the material takes place when the approaching end of the ribbon is free and thus not subject to being stretched or compressed except so far as these deformations take place during the bending process.
Abstract: The specification discloses a kit for making a universal clip. The kit includes a base having a horizontal top surface and a vertical side surface. Mounting apertures are disposed in the base for receiving fasteners to mount the base on support structure. A metallic cylinder and a pin extend upwardly from the top surface of the base spaced apart at a predetermined distance. The base also includes two horizontal bores of different bore depths and an oblique bore extending through the top and side surfaces for use in forming a tip on the universal clip. The universal clip is formed from a metallic wire that is wrapped around the cylinder to form a spring loop and forced against the pin to crook the wire to form two arms. A tip is formed on the end of each arm by bending the ends of the wire using the two horizontal bores in the base.
