To all whom it may concern:

- Be it known that I,R0BERT W. Slims, a citizen of the United States, residin at San Francisco, in the-county of; San rancisco and State of California, have invented certain new and useful Improvements in SectionalLips for Dredge Buckets, of which the following is a. specification.

Dredge buckets of theendless, elevator type are usually rovided with a cutting lip of alloy steel, suc as manganese steel, which assumes the brunt of the digging, and must be replaced from time to time. 'The lip is .usually secured by a course of rivets,-and

when replacement is necessary, much time and labor is expended in'cutting the rivets in order to remove the worn lip and in riveting the new lip. y

he object of. myiinvention is to reduce this expense to a minimum by providinga j sectional lip whereof one element is or may be permanently secured to the bucket, and whereof the other element is in the form of a. tip, which maybe applied or removed with ease and facility.

The nature, characteristic .features and. sec of the invention will be more readily 'un erstoodfrom the following description taken in connection with the accompanying drawings forming a part thereof, where- F igure l. is a perspective view of. a cutting lip embodying my invention. I Fi 2. is a front elevational view showing the 11p elements in detached relation.
