015 NEW YORK, N. Y., A CORPORATION OF NEW YORK BUCKET OR GRAPPLE Application filed July 27, 1932. Serial No. 625,099.

The subject-matter of the present invention relates generally to buckets or grapples, and the improvements are directed to novel and unique means for converting an orange peel bucket, or the like, into a grapple.

Primarily, the object of the invention resides in the provision of means, preferably in the form of flexible elements, which are extended over the top of the bowl of a bucket to serve as retaining means against which the blades of the bucket may push the load while closing.

Another object is to provide means Whereby a bucket of the orange peel type may be easily converted into a grapple for the purpose of handling logs or similar material of irregular dimensions.

till another object of the invention is to provide retaining means to prevent the material being handled from overriding the top of the bowl of a bucket when the closing action of the blades thereof elevates the material toward the top of said bowl.

With these obiects in view. together with others which will appear as the description proceeds, the invention resides in the novel formation, combination, and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawing, and particularly pointed out in the claims.

In said drawing:

Figure 1 is an elevation of an orange peel bucket equipped with the invention.

Fig. 2 is a plan view of the bowl of a bucket, certain portions above the usual blade arms being removed to clearly expose the invention.

Fig. 3 is a sectional detail, slightlv enlarged, and taken on the line 33 of 1.

Fig. 4 is a similar view taken on the line 4- of Fig. 3.

Fig. 5 is a sectional view, slightly enlarged, as viewed on the line 5-5 of Fig. 2.

Fig. 6 is a view like unto Fig. 4, but showing a slightly modified form of fastening means.

Fig. 7 represents a sectional detail showing a modified method of attaching the 5.0 chains to a blade arm.

Referring now more in detail to the accompanying drawing, wherein like characters of reference denote similar parts throughout the several views, let 5 indicate generally the bowl of a bucket which includes a plurality of blades 6. In the present disclosure four blades have been depicted, but it will be understood that this number may be varied as desired.

Those skilled in the art to which this invention appertains will at once recognize the other essential parts of a bucket of the type shown, wherein it will be observed that each blade 6 is provided with a blade arm 7, each arm having its inner extremity pivoted to a 65 cross head 8 positioned below the sheave 9. The head 10 carries the usual guide sheave 11 from which extend certain cables for the operation of the bucket. This arrangement is old and well-known in the art. Depending 7 0 rods 12 are pivotally borne by said head 10 and have their other ends pivotally connected to said blade arms 7 as indicated at 13. The above arrangement permits the raising and lowering of the bucket and the open- #5 ing and closing of the blades when material is to be handled. At this time it is pointed out that each blade arm 7 is riveted or otherwise secured to its companion blade 6, (see Fig. 1), so that these elements form substantially a one-piece structure, and, of course, operate in unison during the opening and closing of the blades.

As pointed out hereinbefore, it is proposed to provide a hood or net embodying a plu- 8'5 rality of flexible elements, in the form of chains, or the like, said elements unitedly forming retaining means which extends over the top of the bowl of the bucket to prevent the material being handled from creeping over the peripheral edges of said bowl. In the present embodiment of the invention a plurality of chains are provided for each blade. said chains preferably being loosely connected with both ends fastened to the'95 periphery of the blade and being of suitable length to permit of their attachment to the top of a blade arm. Upon inspection of Fig.

2 it will be observed that the chains asso ciated with each blade are independent of the .00

chains connected with a companion blade so that no interference is experienced, and since the blade and blade arms are riveted together to form one piece, said chains retain their normal lengths when the bucket opens and closes.

In the drawing the numerals lt, 15 and 16 designate the chains associated with each blade 6, said chains being arranged in spaced relation and having their ends fastened to the periphery of the particular blade with their medial portions suitably secured to an adjacent blade arm 7, as clearly shown in Figs. 1 and 2. The preferred method of attaching the ends of each chain to the upper edge 6a. of the "blade comprises eyebolts 17 having their shank portions passed through suitable apertures in said edge to receive nuts 18, (see Fig. 5), while the means for securing the medial portions of the chains to the blade arms includes U-bolts 19 carrying nuts 20 and 21 as shown in 3 and a. If desired, hook bolts 22 and nuts 23, (see Fig. 6) may be substituted in lieu of the U-bolts, and as shown in Fig. 7 a flat plate 24 may be suitably secured to the tops of the blade arms 7, the extremities of said plates being bent downwardly for connection to the ends of the chain.

It will, of course, be understood that invention is susceptible of attachment to different types of buckets wherein the lower portions of the blades are in the nature of prongs, or the like.

While the present is a disclosure of the preferred embodiment of the invention. it is to be understood that the invention is not limited thereto, as various changes in the minor details of construction, proportion and arrangement of parts may be resorted to without departing from the spirit of the invention as defined in the appended claims.

I claim:

1. In a bucket of the kind including a plurality of blades and arms connected therewith, a plurality of flexible elements extending from the upper edges of said blades to said arms to form retaining means over the bucket.

2. A bucket having blades and arms connected thereto, and means connected to the upper edges of said blades and extended to said arms to form retaining means over the bucket.

3. A bucket having blades and arms connected thereto, a plurality of chains con nected to the upper edges of the blades and extended over said arms to form retaining means when the blades are in open and closed positions.

4. In a bucket of the kind including a plurality of blades and arms connected thereto, a plurality of flexible elements, each element having its ends connected to the upper edge of a blade and having its intermediate portion connected to an adjacent arm, said elements forming retaining means across the top of the bucket.

HERMAN J. BRENDLIN.
