WILLIAM G. WOOD, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR OF ONE-HALF TO FRANK B. MCKEVITT, OF SACRAMENTO, CALIFORNIA.
STEAM-SI-IOVEL BUCKET.
To all whom it may concern Be it known that 1, WILLIAM G. Wool), a citizen of the United States, residing at San Francisco, in the county of San Fran cisco and State of California, have invented new and useful Improvements in Steam- Shovel Buckets, of which the following is a specification.
The object of the present invention is to provide means for positively expelling the contents of a bucket of a steam shovel, dredge or excavator therefrom having a door, which while under the control of the operator of the steam shovel, will operate automatically with the opening of the door of the bucket.
In the accompanying drawing, the figure is a broken side view of a steam shovel bucket equipped with my improved means. 7
gree desired by weights 10. Said ejector 8 1 is provided with transverse bars 12. To the swinging door 18 of the bucket is pivotally attached, as shown at 14, one end of a rod 16 of which the outer end is slotted, as shown at 17, to engage a pin 18 upon the beam 1.
Specification of Letters Patent.
Patented Dec. 10, 1918.
Application filed March 23, 1917. Serial N 0. 156,945.
To said rod is pivoted, as shown at 19, one end of a link 21 of which the other end is pivoted to a lever 22 fulcrumed upon the beam 1, to which lever 22 is pivotally attached one end of a link 23, the other end of which is attached to a rod 24 of a slide valve in a valve chest 26, said valve chest being connected with a pipe 27, for supplying steam to the cylinder 4.
It results from this construction that, when the door of the bucket is swung open, the ejector 8 is rocked downwardly upon its pivots, striking the top of the contents of the dipper and expelling said contents therefrom. v a
I claim:
1. In combination with a bucket of a steam shovel, dredge, or excavator, and having a door, an ejector for ejecting the material from the bucket, means, movable with the bucket, and automatically operated by the opening of the bucket door, for actuating said ejector, and means for energizing said movable means from a distance.
2. In combination with a bucket of a steam shovel, dredge, or excavator having and automatically operated by the opening of the bucket'door, for actuating said ejector, and means for energiz ng said movable means from a distance.
