AUTOMATIC BUCKET.

Specification of Letters Patent.

Patented'uly 31, 1908.

Application filed September 14,1905. Serial No. 2787501.

useful Automatic Bucket, of which the following is a specification'. 1

This invention relates to automatic buckets used in the unloading of coal or other material from barges or similar'l purposes, and has for its object to provide simple and effective means for electrically operating the bucket when enga ing and discharging the material being hanred, l

The invention is illustrated in the accompanying drawings, in which- Figure 1 is an end elevation of the bucket in a closed position. Fig. 2 is a side view thereof. Fig. 3 is a side view of the bucket open, showing a portion of the operating de- .v1ce;v and Fi 4-is a side view of a portion of the electrica l -opera'ting device in the act of closing the bucket.-

In the accompanying drawings the same numerals of reference refer to like parts in each of theviews; and in practice we provide an ordinary .coal-bucket 5 with a cross-bar 6, which is formed to act as an armature and on which the two halves of the bucket 7 and 8 are pivotally. mounted. Connected with this cross-.beam or armature are two guideposts 9 and 10, in which is slidably mounted an electroma et 11, adapted to en age the armature 6 w en magnetized, as will e readily understood. In two standards 12 and 13 on the to of the electromagnet is mounted an axle 1 on which is secured a grooved pnlley 15, around which the-lifting rope or chain 16 is wound, and two ropes or chains 17 and 18, secured to the bucket-head 19, are wound upon this axle as the electromagnet is raised and unwound therefrom as it isv lowered, it being understoodl that the lifting rope or chain 16 is Wound upon the grooved ulle when the electromagnet is in a lowere posltion and unwound therefrom as the magnet is raised, so that the rope 16 is being unwound as the ropes 17 and 18 are being wound upon the axle, and vice versa. On the head 19 of the bucketa plate 20 is secured in which the guide-posts 9 and 10 are slidably mounted.

' In operation the bucket being open, as

shown in Fi 3, is lowered to contact with the coal or ot er material to be handled, and when in engagement with the coal the .wei ht of the bucket being vreleased from the pul ey 15 by continuing to lower the rope'or chain 16- the electroma et will by reason of its own weight be owered on the armature forming part of the cross-beam 6 and Abeing magnetized by an electric current when comingin contact with the armature will engage the same and adhere to it, so that when a am raising the ma et the 'cross-beam wil be raised and the buckets will be closed, this operation being partl shown in Fig. 4. the bucket is close it will be held in that po sition asv long as the magnet is magnetizedt but when the bucket is at the required point by breaking the circuit the magnet will be demagnetized, lthereby releasing lthe armaf ture, and the bucket will open, as shown in Fig. 3, and the contents thereof will be discharged, as will be readily understood.

It will thus be seen that we have provided simple and efiicient means for electrically operating the bucket.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is`

4 1. An automatic ,bucket and an electromagnet mounted thereon adapted to act as a grapple and trip to close and open the bucket.

2. An automatic bucket having an armature mounted on a cross-beam thereof and an ture, for the purpose set forth.

3. An automatic bucket provided with a cross-beam having Van armature mounted thereon, guides on said cross-beam, an electromagnet mounted in saidfguides adapted to contact with said armature, and a grooved pulley and axle mounted on said magnet, a rope or chain in engagement with said pulley adapted to lift the entire bucket, and a second ro e or chain, in engagement with the head o the bucket and with said axle, as and for' the purpose set forth.

4. An automatic bucket provided with a cross-beam having an armature formed When -v IOO thereon, guides on said cross-beam, an elecpulley and axle mounted on said magnet, a names to this specification in the presence of roipe or chain in engagement with said pulley two subscribing witnesses. a

a ted to lift the entire bucket, and ropes FRANK O. CLUKIES. or c ains 1n engagement with the head of the 5 bucket and with said axle, said last-named' ARTHUR M' HAZELL' roles being Wound upon the axle when said Witnesses: pu ley is in a raised position. FRANCIS A. SILLES,

In testimony whereof We have signed our CHARLES H. HAIG.
