3 Claims. (Cl. 30-124) This invention relates to a holding device, more particularly to a wire holding and adjustable tensioning device, and is a continuation-in-part of L. G. Spencer US. application Serial No. 604,865, filed August 20, 1956.
Present methods, involved in the attaching of wires to fixed terminals of a piece of apparatus, are awkward since the operator must hold the wires, mechanically attached to a terminal with a predetermined tensional force, as well as the solder, with one hand, leaving the other hand to hold the soldering iron.
An object of this invention is to provide a wire holding device worn upon a finger of an operators hand leaving the operators hands unconstrained.
Another object of this invention is to provide a wire holding device with the foregoing characteristic having means to adjust the tension of wires which are mechanically attached to terminals of a piece of apparatus.
A further object of this invention is to provide a wire holding device with the foregoing characteristics having means to release the wires from the holding device.
Another object of this invention is to provide a wire holding device with the foregoing characteristics having means to adjust the length of the wire between the wire holding device and the terminals of a piece of apparatus.
A still further object of this invention is to provide a wire holding device with the foregoing characteristics having means to sever a predetermined length of the wire extending from the terminals of a piece of apparatus in which the wire is attached.
These and other objects are obtained by providing a finger ring having a mounting means projecting therefrom on which is superposed a pair of plate-like jaws arranged to grip an elongated object between their cooperating edge faces, one of the jaws being fixed to the mounting means and the other jaw being pivoted to provide eccentric co-action between the co-operating faces, the pivoted jaw being spring-tensioned a predetermined amount to urge it into the gripping position with the stationary jaw.
A better understanding of the invention may be obtained by referring to the following description, taken in conjunction with the accompanying drawings in which like numbers refer to like parts, in which:
Fig. 1 is a perspective view showing the use of the invention;
Fig. 2 is an enlarged perspective view of the wire holding device in which the invention is represented;
Figs. 3 and 4 are views showing in elevation the gripping jaws, forming part of the invention, in the gripping and released positions respectively;
Fig. 5 is a sectional view taken at 5--5 in the direction of the arrows Fig. 4; and
Fig. 6 is a view of the jaws employed in the invention.
Referring to the drawings, there is illustrated a finger ring 1 adapted to mount on the finger 2 of a person, the ring 1 being formed of any suitable material and having an end 3 overlapping the end 4 which allows the 2 ring to fit any size of finger by reducing or enlarging the circumference of the ring by the application of pressure thereto.
Projecting from the ring 1 is the gripping means, mounted on the bracket 5, comprising a stationary grooved jaw 6 secured to bracket 5 and having a rear ing insertion and removal of the wires, and a movable undercut jaw 8 pivoted by pin 9 on bracket 5, tensioned into gripping engagement with jaw 6 by spring 10, one extremity of this spring being attached to bracket 5 by stationary pin 11 and the other extremity to jaw 8 by pin 12, and having a lug 13 with a cutting edge 13 at its outer extremity. The curvatures of the co-operating edge faces 14 and 15 by jaws 6 and 8, respectively are circular in configuration having a center of curvature at C and radius R, Fig. 4. Jaw 8 however is pivoted eccentrically by pin 9, the pivot point thereat being spaced a predetermined distance apart from the center of curvature C of the circular edge face 15. The distances from the pivot point at pin 9 to a succession of points on edge face 15 increase in a clockwise direction and decrease in a counter-clockwise direction. Therefore as jaw 8 is rotated in a clockwise or counter-clockwise direction, the spacing between the edge faces 14 and 15 increases or decreases respectively. Any other method of performing this function may be used.
Associated with the gripping means are the wires 16, 17, contained on the supply reels 18, 19, respectively, for attachment to the terminals 20, 21 respectively, mounted on a piece of apparatus 22. A soldering material 23 is held in one hand of the operator while a soldering iron 24 is held in the other hand.
In the operation of the device, the movable undercut jaw 8, of the jaws 6 and 8 which are shown in the clamped position in Fig. 3, is rotated by hand clockwise so that the edge faces 14, 15 of the jaws 6 and 8 are spaced apart as shown in Fig. 4. The wires 16, 17 are then inserted in this separation and the movable grooved jaw 8 allowed to return, by virtue of spring 10, to the position where the wires 16 and 17 are gripped by the jaws 6 and 8 as shown in Fig. 3.
The operator by slightly twisting his hand, on which the holding device is mounted, and drawing that hand towards himself a predetermined amount, causes the jaw 8 to ride on the wires 16, 17 so that the jaw 8 rotates clockwise sufiiciently to allow the lengths of the wires 16, 17, between the ring 1 and the terminals 20, 21, to be adjusted. By holding the hand, on which the holding device is mounted, so that the wires 16, 17 are just taut, they will remain gripped by jaws 6, 8 by virtue of the action of spring 10 in order that the soldering operation may be carried out.
Upon the completion of the soldering operation, the operator suddenly draws his hand, on which the device is mounted, towards himself maintaining the wires 16, 17 in contact with jaw 8 causing jaw 8 to rotate clockwise since wires 16, 17 ride thereon, allowing the cutting edge 13' to sever wires 16, 17.
What is claimed is:
1. A wire holding device comprising in combination: a finger ring; mounting means projecting therefrom; a pair of oppositely disposed plate-like jaws, their cooperating edge faces being circular in configuration, spaced apart so as to grip an object between the cooperating edge faces, one of the jaws being fixed on the mounting means and having its edge face grooved, the other jaw being undercut, pivoted on the mounting means so that its axis of rotation is eccentric to the center of curvature of its co-operation edge face to provide eccentric co-action between the co-operating edge faces when the pivoted jaw is rotated in a clockwise or counter- 3 I 4 a clockwise direction; resilient means attached to the of the pivoted jaw, having a cutting edge projecting pivoted jaw and to the mounting means and arranged to against the co-operating face of the stationary jaw when urge the co-operating edge face of the pivoted jaw into the pivoted jaw is rotated in a clockwise direction. gripping-relation with the coroperatingnedge face hot the fixed jaw. h M d d th 1 1 5 References Cited in the file of this patent 2. wire 0' ing cvice in accor ance wi .c aim in which the diameterof the'said ring is adjustable.
