Abstract
Abstract Opposed dies having diverging intercalated or interlocking fingers extending from their faces are arranged for movement toward and away from each other under the influence of pneumatic pistons. A broomed end of a strand having a clamp secured a predetermined distance from the end is positioned vertically between the dies so that as the dies move toward each other the broomed ends of the wires are bundled together into pseudo strand form by the intercalated fingers and then held by the dies while an end fitting is slipped over the end of the strand. The dies are then opened and the fitting is slid down over the strand to rest upon the face of the clamp in predetermined alignment for securing to the strand.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
204 words
An apparatus for applying fittings to broomed ends of wire strand comprising: a. slotted positioning means; b. stationary support means on opposite sides of said slotted positioning means; c. first and second cooperating opposed die means respectively mounted upon said stationary support means for relative movement toward and away from each other adjacent the slotted positioning means; d. said die means when brought into substantially abutting position delineating between them a die cavity at least a portion of which conforms substantially to the outside normal croSs-sectional dimensions of a wire strand upon which a fitting is to be mounted; e. at least two diverging fingers extending at an angle from each said die means; f. the fingers extending from said first die means overlapping the fingers extending from said second die means in an intercalated relationship, the distance between the outer ends of said fingers of each die means being at least equal to the widest brooming of the broomed end of said strand, said fingers of each die means being positioned to extend past the opposing die means when said die means are brought into abutting position; and g. prime mover means to move said die means towards and away from each other.
Claim 2
Independent Claim
204 words
An apparatus for applying fittings to broomed ends of wire strand comprising: a. slotted positioning means; b. stationary support means on opposite sides of said slotted positioning means; c. first and second cooperating opposed die means respectively mounted upon said stationary support means for relative movement toward and away from each other adjacent the slotted positioning means; d. said die means when brought into substantially abutting position delineating between them a die cavity at least a portion of which conforms substantially to the outside normal croSs-sectional dimensions of a wire strand upon which a fitting is to be mounted; e. at least two diverging fingers extending at an angle from each said die means; f. the fingers extending from said first die means overlapping the fingers extending from said second die means in an intercalated relationship, the distance between the outer ends of said fingers of each die means being at least equal to the widest brooming of the broomed end of said strand, said fingers of each die means being positioned to extend past the opposing die means when said die means are brought into abutting position; and g. prime mover means to move said die means towards and away from each other.
Claim 3
Dependent Claim
26 words
An apparatus according to claim 1 additionally comprising clamp means adjacent said slotted positioning means to secure said strand during the movement of said die means.
Claim 4
Dependent Claim
35 words
The apparatus of claim 1 wherein said slotted positioning means has an upper surface at least a portion of which is substantially level and said cavity delineated by said die means is substantially vertically oriented.
Claim 5
Dependent Claim
24 words
The apparatus of claim 3 additionally comprising clamp means under said slotted positioning means to secure said strand during movement of said die means.
