Abstract
Abstract There is provided a coil upending and transporting apparatus which includes a main frame having means for allowing the frame to be suspended from a suspension means, and a sub-frame pivoted to the main frame at a horizontal axis located below the suspension means. Power means such as hydraulic cylinders are provided for positively pivoting the sub-frame with respect to the main frame about the axis. The sub-frame includes support means for engagement under a coil whose axis is vertical, and an elongate holding mandrel disposed so as to be parallel with the axis of a coil at one end of which the support means is engaged. Control means are also provided for moving the holding mandrel selectively (1) in the direction of its elongation, and (2) perpendicular to both its own elongation direction and the direction of said horizontal axis.

Claim 1
Independent Claim
182 words
A coil upending and transporting apparatus comprising: a main frame having means for allowing the frame to be suspended from a suspension device, a sub-frame pivoted to said main frame at a horizontal axis located below said means, power means for positively pivoting the sub-frame with respect to the main frame about said axis, the sub-frame including: (a) support means for engagement under a coil whose axis is vertical, (b) an elongate holding mandrel disposed so as to be parallel with the axis of a coil at one end of which the support means is engaged, and (c) control means for moving said holding mandrel selectively (1) in the direction of its elongation, and (2) perpendicular to both its own elongation direction and the direction of said horizontal axis, the horizontal axis at which the sub-frame is pivoted to the main frame being substantially aligned with the centre of gravity of the sub-frame when carrying a coil of average weight and size, thereby reducing the work required of the power means to positively pivot the sub-frame and coil about said horizontal axis.
Claim 2
Dependent Claim
182 words
A coil upending and transporting apparatus comprising: a main frame having means for allowing the frame to be suspended from a suspension device, a sub-frame pivoted to said main frame at a horizontal axis located below said means, power means for positively pivoting the sub-frame with respect to the main frame about said axis, the sub-frame including: (a) support means for engagement under a coil whose axis is vertical, (b) an elongate holding mandrel disposed so as to be parallel with the axis of a coil at one end of which the support means is engaged, and (c) control means for moving said holding mandrel selectively (1) in the direction of its elongation, and (2) perpendicular to both its own elongation direction and the direction of said horizontal axis, the horizontal axis at which the sub-frame is pivoted to the main frame being substantially aligned with the centre of gravity of the sub-frame when carrying a coil of average weight and size, thereby reducing the work required of the power means to positively pivot the sub-frame and coil about said horizontal axis.
Claim 3
Dependent Claim
30 words
The apparatus claimed in claim 1, in which the support means includes two spaced-apart parallel tines thus defining a fork arrangement adapted to engage one end of a cylindrical coil.
Claim 4
Dependent Claim
40 words
The apparatus claimed in claim 1 or claim 2, in which the said main frame includes two vertical spaced-apart members joined by an upper linking member, the linking member having a central opening for engagement by an overhead supporting device.
Claim 5
Dependent Claim
77 words
The apparatus claimed in claim 1 or claim 2, in which said holding mandrel is supported on the end of a first member which is in telescoping engagement with a second member, the holding mandrel being perpendicular to the first and second members, said control means including first screw means for moving the second member toward and away from said support means, and second screw means for telescoping the first member with respect to the first member.
