SPECIFICATION forming part of Letters Patent No. 567,469, dated September 8, 1896. i y

Application filed June l, 1896.- Serial No. 593,861. (No model.)

` T o all whom it ma'y/ concern:

Beit known that I, WALTER GnisooM, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Devices for Attaching Elevator-Buckets to Belts, of which the following is a specification.

One object of inyinvention is to provide for attaching elevator-bucketsto belts Without the use of the usual rivets or bolts, so that a bucket may be attached to any desired portion of the belt or readily shifted from one point on the belt to another, a f urther object being to provide for the use of the same fastenin gs upon belts and buckets of different widths. These objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in Whiohc Figure l is a'perspective View of an elevator-bucket and part of the elevator-belt, illustrating my improved bucket-fastening. Fig. 2 is a sectional plan view, and Fig. 3 is a detached elevation of one of the fastening devices.

A represents part of the elevator-belt, and B a bucket secured thereto. This bucket may be made in any convenient manner, as the construction of the bucket forms no particular part' of my invention, the latter relating to the means adopted for securing the bucket to the belt. y

The bucket shown inFigs. l and 2 consists of sheet metal bent into and secured in the proper form, the bucket having upon the top a stiftenin g or strengthening band composed of inner and outer U-shaped strips D D', the ends of which overlap on the sides of the bucket and are secured together and to said sides of the bucket by rivets a.

In the back of the bucket and in its strengthening-strip D are formed openings b for the reception of tonguesor fingers d, struck up from attaching-plates F, each of which has its outer portion bent rearward and inward, so as to form ahook f for embracing the edge of the belt A and clasping or confining the same. The openings h are so located in the bucket that when the attaching-plates F are applied to the bucket the distance between the loops or hooks of said attaching-plates Will preferably be just equal to or slightly less than the width of the belt, so that said hooks Will iit snugly to or Will slightly compress the belt laterally. Each hook is preferably recessed in the center, as shown in Fig. 3, so as to increase its hold or grip upon Vthe edges of the belt, the bucket can be very readily applied to or removed from the belt by simply bending or buckling the latter, so as to reduce its Width suffcienty to permit of the Withdrawal of said edges from the hooks in detaching the bucket, or so as to permit of the slipping of the edges of the belt into the hooks in attaching the bucket, the flattening out of the belt in the latter case causing the edges of the same to engage with the hooks and thus insuring the secure confinement of the bucket to the belt.

By providing the bucket with independent attaching devices at each edge the same devices may be used in connection with buckets and belts of different Widths, the openings b being so located on each bucket that when the attachingplates are confined to the bucket the hooked edges of said plates-Will bear such relation to each other as to properly receive the edges of a belt of the Width for which the particular bucket is intended.

In all cases the attaching devices are independent of the buckets, this feature of my invention being adopted Whether I use independent attaching-plates at each edge of the bucket or a single plate extending entirely across the bucket.

Having thus described my invention, I clainr and desire to secure by Letters .Patentv l. The combination of an elevator belt and bucket, with independent bucket-attaching plates secured to the bucket and each having a hook adapted to embrace the edge of the belt, substantially as specified.

2. The combination of an elevator belt and bucket, With a bucket-attaching device hav- IOO ing hooks adapted to clasp the edges of the belt, said hooks being recessed so as to form upper and lower prongs projecting inwardly from the edges of the belt, substantially as specified.

3. The combination of an elevator-belt and its buckets, with'b ueketattacliing plates hav-- ing hooks adapted to clasp the edges of the belt, and means for detachablyrconnecting the buckets to said plates, substantially'as specified.

4. The combination of the elevator belt and buckets, With attaching=plates havinghooks adapted to clasp the edges -of the belt,.vand tongues or fingers passing through openings .in the buckets and bent down Aon the .inside of. the same, substantially asspecified.

5. .The combination ofani elevator c up or bucket, with a pairof independent. platessecured thereto and each havin hook adapted to clasptheedges of the elevator-belt, sub- :stantially .as specified.

vthe upper edge ofthe bucket, andhooks adapted :to claspy the elevator-belt, substantially as speciiied.

In testimonywvhereof I :have signed my name to this-specification vin thepresence of `twosubscribing Witnesses.
