Abstract
A device is disclosed for forming closable spring snaps from wire. The device is in the form of a hand tool and includes an elongated solid body having a plurality of pins fixed to and protruding outwardly from the body, in conjunction with a bore through the body and a groove cut into the side of the body. The pins, bore and groove are used in various combinations to form an eyelet at one end of a length of wire, to form an open latch loop at an opposite end of the length of wire, and to bend the length of wire intermediate the ends thereof with the wire bent back toward itself whereby the open latch loop is engageable with the one end of the wire inwardly of the eyelet to form a closable spring snap.
Claims22
A device for forming closable spring snaps from wire, comprising:
- a unitary elongated body having a longitudinal axis;
- means on said body for forming an eyelet at one end of a length of wire and for forming an open latch loop at an opposite end of the length of wire;
- and
- means on said body for properly positioning and facilitating bending said length of wire intermediate the ends thereof with the wire bent back toward itself whereby said open latch loop is engageable with said one end of the wire inwardly of said eyelet to form a closable spring snap, including means on one side of said body for positioning and holding said open latch loop and means on said one side of the body protruding outwardly therefrom and longitudinally axially spaced from said means for positioning and holding said open latch loop and about which the length of wire is bent back onto itself to properly position the loop engageable with the wire inwardly of said eyelet.
A device for forming closable spring snaps from wire, comprising:
- an elongated body having a longitudinal axis;
- a pair of spaced members fixed to and protruding outwardly of said body for forming a closed loop at one end of a length of wire with a free end portion of the wire extending away from the closed loop and for forming an open latch loop at an opposite end of the length of wire, one member providing an abutment stop for the wire and the other member providing a rounded surface about which the wire is bent to form the closed loop and the open latch loop;
- means on said body for twisting said free end portion of the wire about the length of wire inwardly of said closed loop to completely form an eyelet at said one end of the length of wire;
- and
- means on said body for properly positioning and facilitating bending said length of wire intermediate the ends thereof with the wire bent back toward itself whereby said open latch loop is engageable with said one end of the wire inwardly of said eyelet to form a closable spring snap, including means on one side of said body for positioning and holding said open latch loop and means on said one side of the body protruding outwardly therefrom and longitudinally axially spaced from said means for positioning and holding said open latch loop and about which the length of wire is bent back onto itself to properly position the loop engageable with the wire inwardly of said eyelet.
A device for forming closable spring snaps from wire, comprising:
- an elongated body having a longitudinal axis;
- a pair of spaced pin-like members fixed to and protruding outwardly of said body for forming a closed loop at one end of a length of wire with a free end portion of the wire extending away from the closed loop and for forming an open latch loop at an opposite end of the length of wire, one pin-like member providing an abutment stop for the wire and the other pin-like member providing a rounded surface about which the wire is bent to form the closed loop and the open latch loop;
- means for receiving and positioning the length of wire after said closed loop is formed, and a third pin-like member fixed to and protruding outwardly of said body for engaging said free end portion of the wire while so received and positioned and twisting the free end portion about the length of wire inwardly of said closed loop in response to rotation of the closed loop to completely form an eyelet at said one end of the length of wire;
- and
- means on one side of said body for holding said open latch loop after so formed, and a fourth pin-like member fixed to and protruding outwardly of said body on said one side thereof and longitudinally axially spaced from said means for holding said open latch loop for bending said length of wire thereabout while the open latch loop is so held until the wire is bent back toward itself so that said open latch loop is engageable with said one end of the wire inwardly of said eyelet to form a closable spring snap.
