GRAPPLING YOKE FOR HANDLING AND CONVEYING- WIRE BALES AND THE LIKE. i

Application med May a, 1924. Serial No. 7151,799.

To all whom it may concern: I

Be it knownthat I, IsAAc A. RYAN, a cit1- zen of the United Statesof America, res1ding at Ironton, in the county of Lawrence and State of Ohio, have invented certain new and useful Improvements in Grappling Yokes for Handling and Conveying Wire Bales and the like, of which the following is a specification. V

This invention relates to certain new and useful improvements in grappling yokes especially designed for the handling and con veying of wire bales and the like for conveying the wire bale to a bath for treatment prior to the forming of the wire into 113.118, and is also capable for conveying rods or plates.

The primary object of the invention is to provide a grappling yoke preferably suspended from the chain of a crane wherein the yoke hooks or arms are pivotally supported upon a cross bar having keeper hooks manually releasable and adapted for cooperation with the arms for locking the same in bale or bar suspending position.

With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters designate corresponding parts throughout the same,

Figure 1 is a side elevational view of a grappling yoke constructed in accordance with the presentinvention, a bale of wire illustrated by dotted lines shown as supported thereby,

Figure 2 is a side elevational view of the grappling hook in its released position,

Figure 3 is a top plan view,

Figure 4: is an end elevational View,

Figure 5 is a vertical cross-sectional view taken on line VV of Fig. 1 showing the chain hook of the crane released from the bracket bar of the grapple and lowered into engagement with the conical block of the grapple to laterally displace the chain hook with respect to the suspending bracket bar,

Figure 6 is a vertical cross-sectional view taken on line VI-VI of Fig. 1,

Figure 7 is a horizontal sectional view taken on line VII-VII of'Fig. 1 showing of spacing blocks 4 is positioned between the bars 1 at points spaced from the ends of .the bars and have the ends of an inverted substantially V-shaped bracket rod 5 anchoredtherein that extends above the cross- .head as shown in Figs. 1,2 and 5. -A centrally positioned block 6 having a tapering head 7 is secured as at 8 between the spaced side bars 1 and is disposed directly beneath the apex of the b-racketrod 5. .The grappling yoke is adapted to be suspended by the hook 9 carried by the lower end of the chain 10 depending from a crane with the hook 9- engaging the bracket rod 5 for elevating and moving the grappling yoke. I

A pair of grappling arms are pivotally supported between the spaced side bars 1, each grappling arnrbeing of angle formatlon and embodying leg portions 11 and 12, a grappling arm being associated witheach end of the cross head and being pivotally supported upon the pin 13 extending between the lugs 14 that are carried by the brackets 15 which are secured as at 16 to the lower flanges 2 of the side bars, the upper cam-shaped end 11 of the leg portion 11 of each grappling arm extending above the side bars 1 when the leg portion 11 is vertically positioned as shown in Fig. 1. r

A. keep-er loop is pivotally supported upon the crossheadat each end thereof for cooperation with the longer edge of the upper endportions of the grappling arms to hold the lower leg portions 12 in elevatedclosed position as shown in Fig. 1, the keeper loops, as shown in Fig. 3.embodying side legs 17 connected by cross heads 18 having cam-shaped lower faces at their free ends while the other ends thereofenclose the upper ends 3? of the spacing blocks 3 and are pivotally connected thereto by the pins19,

are pivotally mounted.

6. In a grappling yoke for handling wire bales, a cross head, a pair of cooperating grappling arms pivotally depending from the cross head, manually releasable devices adapted for locking the grappling arms when manually moved into their operative position, said devices including keeper loops pivoted to the ends of the cross head, said grappling arms being of angle formation with one end thereof positioned for engagement by the keeper loops when in operative position, the cross head embodying spaced side bars, a spacing block at each end thereof and upwardly directed extensions on the spacing blocks upon which the keeper loops are pivotally mounted.

7. In a grappling yoke, a cross head, grappling means carried by said head, a crane hook engaging member carried by the cross head and projecting upwardly therefrom, and means carried by the cross head below the aforesaid member adapted for laterally displacing the crane hook when lowered relative to the said member to prevent engagement of the hook and member when the hook is again raised.
