Patented Apr. 17, 1917.

Application filed February 14, 1916. Serial No. 78,100.

To all whom it may concern:

Be it known that 1, JOHN H. WrLsoN, a citizen of the United States, residing at San Mateo, in the county of San Mateo, State of California, have invented a new and useful Hoisting-Bucket, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a scraper bucket for hoisting or elevating sand, rock, gravel, earth-or mud and its object is to produce a bucket which will be self closing and which can be opened either by hand or by having the bucket pass a suitable obstruction which will release the latch.

Another object of the invention is to provide a bucket which will not require the assistance of a man to load it, the bail being arranged with short chains which will prevent the bucket from turning over.

Other objects of the invention will appear as the description proceeds.

An embodiment of the invention is shown in the drawing in which the same reference numeral is applied to the same portion throughout, but I am aware that there may be many modifications thereof,

Figure 1 is an edge elevation of the complete bucket as it appears when loaded and being transported from one place to another,

Fig. 2 is a side elevation of the bucket looking from the right, Fig. 1,

Fig. 3 is a view illustrating the bucket in use gathering up a load,

Fig. 4 illustrates the position of the two parts of the bucket when the latch has been opened,

Fig. 5 is a side elevation of the bucket looking from the left, Fig. 1, and on a slightly smaller scale, and

Fig. 6 is a view in section of one of the bucket hinges on the line 66, Fig. 4.

The numeral 1 indicates the bucket bail which has a rod 2 to prevent the bail from collapsing and thus injuring the bucket. The bucket bottom 3 is shaped like a common form of scraper with two steel runners 4 and 5. The bail is connected to the top of the bucket with suitable hinge pins 6 and 7, reinforcing straps 8 and 9 being used to assist in connecting the bail and bucket.

Two chains 10 and 11 connect the bail with the corner of the bucket which cuts into the pile of material being attacked for the purpose of preventing the bucket from being overturned should a rock or be encountered.

The end of the bucket 12 which forms the bottom thereof when the bucket is loaded inclines at about 45 degrees from the vertical when the bucket is in use in order to insure the complete dumping of the bucket contents. A strap 13 having projecting arms 14 and 15 passes around the bottom and affords the means whereby the top is connected to the bottom of the bucket. A plate 16 and ring 17 are provided to enable the bucket to be conveniently pulled backward whenever necessary.

The bucket top comprises a cover 20 with sides 18, 19 and a bottom 21 shaped substantially like the other half of the bucket except that it is not provided with the cutting edge. The bucket top has a lever 23 pivoted thereon which lever has a curved a stump over top portion 24 to enable the lever".

to be operated by striking a fixed projection 25 along the path of the bucket.

Secured on the side of the bucket top is a plate 26 to which oppositely extending bars 27, 28 are pivoted, said bars passing under cleats 29, 30 and engaging notches in the ends of the arms 14, 15 to lock the two parts of the bucket together.

The cleats 29, 30 have projecting horns 31, 32 to which are secured springs 33, 34 to hold the two scraper parts together. Cables 35, 36 passing through rings 37, 38 connect the latches with the lever 23 so that when said lever is moved the latches will be opened. At the open end of the bucket the two parts of the bucket are connected together by means of hinge links 39, 40, two at each side.

In operation the bucket may be pulled forward by the cable 41 and returned by the cable 42 after its load has been dumped. The dumping may be accomplished by hand or by having the loaded bucket pass a fixed obstruction as may be desired, but as soon as the bucket has been dumped it will be automatically locked together again.

In order to protect the latches and also to provide handles U-shaped plates 43, 44 are provided on the sides of the bucket.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States, is as follows, modifications within the scope of the claims being expressly reserved:

1. In a hoisting bucket a scraper, rigid latch arms connected therewith, a cover formed to [it the scraper, and pivoted thereto, pivoted latches on the cover to cooperate with the latch arms, springs to hold the latches in engagement with the latch arms, a pivoted plate on the cover, and cables connecting said plate and latches for releasing the latches.

2. In a hoisting bucket a scraper, rigid latch arms connected therewith, a cover formed to fit the scraper, and pivoted thereto, pivoted latches on the cover to co- Copies of this patent may be obtained for operate with the latch arms, springs to hold the latches in engagement with the latch arms, a pivoted plate on. the cover, connec- 1.5 tions between the pivoted plate and latches whereby the latches may be operated and guards adjacent each latch to prevent the latches from being accidentally disengaged.

In testimony whereof I have hereunto set 20 7 my hand this 4th day of February, A. D. 1916.

JOHN'H. WILSON.
