This invention is described herein particularly 1 vertical.

Conveying Means, Serial No. 699,476, filed September 26, 1946, adapted to convey up-ended coils from vertical storage stacks thereof to apparatus wherein the coils are to be mounted horizontally, being employed for turning the coils from vertical to horizontal position.

Referring now to the drawings, there is shown at l a carrier adapted to be positioned to receive a coil 0 carried on a sling F from a hoist-line implement (not shown) with the axis of the coil Sling F and the hoist-line implement are particularly described in our said copending application. For the purposes of this disclosure, it is to be noted that the sling comprises a coilsupporting platform 3 having a spindle 5 extending through the eye of the coil and provided with an undercut, grappling-hook-engaging knob 6.

The carrier I is pivotally mounted for vertical swinging movement in a supporting framework comprising a pair of vertical standards I and 9 joined by angle members II.

The carrier comprises a generally U-shaped frame (note Fig. 7) made up of spaced side plates I3 and I5, 2. bottom plate I1, and a bottom angle member 18. This frame is pivotally mounted in the upper ends of the standards for rotation about a horizontal axis by means of trunnions l9 and 2| fixed to and extending laterally outward from the side plates adjacent their free forward edges. The frame is adapted to be swung through an arc of from a position wherein bottom plate I! is vertical (Figs. l-3) to a position wherein plate I! is horizontal with side plates l3 and 15 extending upward therefrom (Figs. 4-6). These positions are determined by a pair of limiting stops 23 and 25 on the frame cooperable with the standard 9.

Carrier I is preferably power-driven between the aforesaid positions, although it will be understood that it may be swung manually. As illustrated in Figs. 1 and 2, a platform 21 is carried by standard I and an additional standard 29. A reversible motor 3| and a speed reducer 33 are mounted on this platform, a belt drive 35 connecting the motor shaft and the input shaft of the speed reducer. The output shaft of the speed reducer is connected through a speed-reducing gear train 31 to a gear 39 fixed on trunnion I9 for rotating the carrier. Suitable controls and limit switches (not shown, being well known) are provided for motor 3| so that it may rotate carrier in either direction and stop when either of stops 23 or 25 engages standard 9, as will be readily understood. The carrier I has means mounted thereon for carrying a coil on its side when in the Fig. position and for carrying the coil vertically up-ended when in the Fig. 1 position.

The means for carrying a coil on its side comprises an adjustable coil cradle 4| mounted within the carrier in such manner as to receive the coil when the carrier is turned to the Fig. 5 position and which may be adjusted for centering coils of difierent diameters for a purpose to be described. Cradle GI is carried on a shallow V-shaped base plate member 43 fixed within the carrier with its apex 45 abutting bottom plate I! and angle I8 and its side margins secured to side plates I3 and I5 as by welding 41.

The cradle comprises two adjustable sets of curved fingers 5| and 53 which may be adjusted from a lowermost position on the base plate 43 wherein they carry a coil of largest diameter to be handled to raised positions for carrying coils of smaller diameters. Fingers 5| are secured as by welding at one end to a pin 55 pivotally retained on one wing of member 43 by clips 57. Pin 55 extends longitudinally of the cradle and fingers extend transversely therefrom across the apex of member 43, being spaced longitudinally on the pin. A longitudinal bar 59 .is welded to the upper side of fingers 5! at their free ends. Fingers 53 are secured as by welding at one end to a pin 5| pivotally retained on the other wing of member 43 by clips 53. Pin GI extends longitudinally of the cradle and fingers 53 are spaced longitudinally and extend transversely in intermeshing relation with fingers 5|. A longitudinal bar is welded to the upper side of fingers 53 at their free ends. The coil is carried by the bars 59 and 65 cradled therebetween.

Adjustment of the fingers 5i and 53 is effected by means of a camrning bar 61 pivoted at 69 on member 23. This bar extends longitudinally under the fingers and is formed with an ear II at one end extending outward across the end .of the cradle. A screw-threaded link I3 is pivoted to the ear. This link is adapted to be moved in one direction or the other to pivot the bar 5'! by an operating rod 15 threaded in the link I and journalled in a pivoted bearing 11 carried by the bottom plate I! of the carrier I. A hand crank I9 is fixed on the outer end of rod I5. It will be clear that when the crank and rod are turned to move link 13 to the right, as viewed in Fig. 8, bar 5? is pivoted counterclockwise to cam fingers 5I and 53 to elevate bars 59 and 6.5 to the position illustrated in full lines in Fig. 8.

The above cradle construction is such that bars 59 and 65 may be raised or lowered to carry coils of different diameters with the axis of a coil approximately intersecting the horizon tal pivotal axis of the carrier I as defined by trunnions I9 and ill. The purpose of this adjustment is to enable a coil to be positioned with its center of gravity approximately on the horizontal pivotal axis of the carrier so as to reduce to a minimum the torque required to rotate the carrier. The arrangement is also such that coils of different diameters may all be turned to horizontal position with their axes at approximately the same height above the floor for convenience in handling.

The carrier I is also provided with means for carrying a coil on end which is retractable after the coil has been turned to horizontalposition to permit removal of the coil sling F. This means comprises two L-shaped supporting brackets .81, the arms .83 of which provide supporting means for carrying a coil on end when the carrier is in the position of Fig. 1. The other arms of the brackets form levers for pivoting arms 83 in such a way that they are laterally retractable from coil-carrying position to a retracted position to clear the end of the coil so that the sling may be withdrawn.

Each arm 85 is formed with an enlarged head 8'! at its free end, the head having upper and lower apertures 89 and 9|, respectively, ofiset laterally outward from the plane of the bracket. The brackets are identical except that the head of one bracket is reversed with respect to the other so that the heads extend laterally outward. One arm 85 extends from the lower end 93 of the cradle M under the cradle in the space 95 between member 33 and the bottom plate I1 and angle I8 on one side of the carrier. The other arm 85 is similarly disposed in space 95 at the other side of the carrier. The arms 85 are pivoted on axes parallel to the planes of the bracket but offset outward therefrom on pivot pins 91. These pins may extend either through apertures 89 or through apertures 3| in the heads 81. As illustrated herein, pins 91 extend through apertures 9 I. These pins are removably mounted in the carrier, extending through aligned apertures provided in web plates 99 and the bottom plate ll of the carrier. Web plates 99 are welded at their ends to the side plates I3 and I5 of the carrier and to the member 43 adjacent the upper end of the cradle. The pins 97 may be withdrawn from heads 87, apertures iBI being provided in member 33 for access to the pins, and brackets 81 repositioned with pins 9.! extending through apertures 89 .to lower arms 8.3 relative to the cradle to carry wider coils with the center of gravity of the coil approximately on the horizontal pivotal axis of the carrier.

The brackets .BI are swingable .laterally outward on the axes of pins .91 from the solid-line position of Figs. 4 and .5 wherein arms 83 extend upward from the end .93 of the cradle in parallelism and spaced apart a distance less than the width -of the platform 3., to the dotted-line position of these figures wherein arms 83 are spaced apart a greater distance than the width of the platform 3 so that the sling may be withdrawn from the coil. The first of these positions constitutes the position of arms v83 for carrying the coil on end, and the second .is the retracted position for clearing the end of the coil. The brackets are adapted to be retained in the first position by means of latch blocks I83 pivoted at JD] on carrier I and engageable with the sides of 55 arms85. These blocks are biased by over-centering tension springs I 85 to a position against plate I! wherein they engage arms 85 to maintain coilsupporting arms 83 in the Fig. 2 position. They may be swung away from base plates l1 against the side plates I3 and I5 to permit the brackets to be swung laterally outward. In this latter position the springs i923 are over-centered to bias the blocks to said position. It will be understood that when latch blocks I83 are in the Fig. 2 position, the brackets are gravity-biased into engagement therewith. Arms 85 abut base plate I! and slide thereon in the course of their swinging movement. The weight of the brackets is thus borne by the bottom plate I? and angle member lustrated in Fig. 4 by the arcs A. This permits arms 83 to be swung to clear the platform 3.

Operation is as follows:

The motor 3| is energized to rotate the carrier I to the position of Figs. 1-3 wherein the cradle 4| is vertical and coil-supporting arms 83 extend horizontally outward and forward from the lower end 93 of the cradle in position to carry a sling F and a coil thereon by the lower end thereof. Arms 83 are retained in this position by swinging latch blocks I03 to engage the levers 85. The cradle 4| is adjusted by turning crank 79 to position bars 59 and 65 at the proper elevation above plate member 43 so that the coil to be turned will ultimately rest on its side in the cradle with its axis approximately intersecting the horizontal pivotal axis of the carrier I. Brackets 8I are pivoted with pins 91 extending through the appropriate apertures 89 or 9| according to the width of the coil to be handled so that the center of gravity of the coil will be approximately in said pivotal axis.

The sling F with coil C thereon is deposited on the arms 83 by a hoist-line implement (not shown) such as disclosed in our aforesaid copending application with platform 3 of the sling resting on the arms. After the implement has been disengaged from the knob 6 of the sling, motor 3| is energized to rotate the carrier I through 90 to the position of Figs. 4-6 wherein the cradle 4| is horizontal and arms 83 extend upward from the forward end thereof. Latch blocks I03 are swung on their pivots out of abutting relation to arms 85, and the brackets are then manually swung laterally outward to the dotted-line position of Figs. 4 and 5. In this position, supporting arms 83 are clearof the platform 3 of the sling, and the sling may be pulled out of the coil.

Thus, the turning apparatus of this invention is adapted to receive a coil on end, turn it to a horizontal position resting on its side, and also to permit retraction of the support for the end of the coil to clear said end for removal of a coil supporting sling or for any other desired purpose. It will be understood that the turning apparatus is also adapted for reversal of this procedure, i. e., to receive a coil horizontally with the arms 83 retracted so that a sling may be inserted in the coil, then to have arms 83 moved to coil-carrying position, and the carrier I turned to bring the coil to vertical position, resting on end on arms 83, whereupon it may be hoisted above the turning apparatus by means of the sling. The apparatus is adjustable to accommodate coils of different diameters and widths in proper balance by reason of the provision for adjustability of cradle 4| in accordance with the coil diameter and the provision for adjustability of brackets 8| in accordance with coil width to position the center of gravity of the coil approximately in the pivotal axis of the carrier I.

In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

As many changes could be made in the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
