W. S. MORGAN MEANS FOR GRINDING DREDGE BUCKETS AND THE LIKE Nov. 10, 1925- Filed Aug. 5, 1922 144 5. Morgan Patented Nov. 10, 1925.-
UNITED STATES PATENT OFFICE.
WALTER S. MORGAN, OF HIGH BRIDGE, NEW JERSEY, ASSIGNOR TO TAYLOR-WHAB TON IRON AND STEEL COMPANY, OF HIGH BRIDGE, NEW JERSEY, A CORPORA- TION OF NEW JERSEY.
MEANS FOR GRINDING DREIDGE BUCKETS AND THE LIKE.
Application filed August 3, 1922. Serial No. 579,404.
To all whom it may concern:
Be it known that I, VVAL'rn-n S. MORGAN,
a citizen of the United States, residing at High Bridge, in the county of I-Iunterdon and State of New Jersey, have invented certain new and useful Improvements in Means for Grinding Dredge Buckets and the like, of which the following is a specification.
This invention provides a method and means for the rapid and economical grinding of dredge buckets and the like. Dredge buckets are ponderous constructions, usually of unmachinal'wle steel, and have heretofore ofl'ered serious difficulties in grinding, their shape and weight, up to two tons, necessitating that they be ground one at a time. My invention makes it possible to grind them in multiples of two or more.
The nature, characteristic features and scope of the invention will more readily be understood from the following description taken in connection with the accompanying drawing, wherein,-
Figure 1 is a perspective view of apparatus for carrying out the method.
Fig. 2 is a front elevational view.
Fig. 3 is a top view; and
Fig. i is an end. view.
According to my invention I center the buckets so that they straddle one another or interlock, with similar eyes in coincidence and two of them overlapping. In the illustrated embodiment of the invention, use 35 is made of a pair of rotatable face plates 5 connected by adjustable spacing and work support plates 6. The face plates are peripherally supported on flanged rollers 7 arranged in pairs and driven by suitable means (not shown) in order to impart rotary movement to the face plates.
The buckets 8 are supported on the plates 6, so that their eyes 9 are in registry and two of them overlapping, and they are secured in such relation by V blocks 10, or other appropriate means adjustable with respect to the Work plates 6 to which they are clamped through the medium of T slots or the like. The grinding elements 11 are then brought into play in the usual manner to internally grind the eyes 9, the face plates being bored, as at 12, to permit the passage of the grinding elements. It will be evident to those skilled in the art that by my method of grinding dredge buckets,
in multiples of two or more, I not only effect a desirable economy, but obtain uniformity in grinding.
Having described my invention, I claim,-
1. In a means for grinding dredge buckets and the like, a rotatable work holder, means for supporting a plurality of dredge buckets therein with the eyes of one alined with the eyes of the others and concentric with the axis of the holder, said holder being formed for the passage of lapping tools through such alined eyes.
In an apparatus for grinding dredge buckets in multiples of two or more, a peripherally-supported holder having an axially-disposed opening for the passage of a grinding tool, and means for supporting the dredge buckets to cause their eyes to register in alignment with such axially-disposed opening.
In testimony whereof I afiix my signature.
WALTER S. MORGAN.
