Application filed July 16, 1923.

To all NEIL Hi2 it may concern.

Be it known that I, Emmi: J. IvuizsoN, a citizen of the United States, residing at Ietersburg, in the Territory of Alaska, have invented new and useful Improvements in lVashers, of which the following is a specitication.

This invention contemplates the provision of a washer made up of two complementary sections designed for locking association whereby the sections can be quickly and easily assembled or disassembled as the occasion requires, and either section may be replaced by a new section when necessary.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawing, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawing forming part of this application, like numerals of reference indicate similar parts in the several views, and wherein:

Figure 1 is a plan view of the washer partly assembled.

Figure 2 is a similar View of the washer wholly assembled.

Figure 3 is a detail view of the sections separated.

Figure l is a fragmentary sectional view taken on the line. 4W4 of Figure 2.

deferring to the drawing in detail, and 11 indicate the respective sections of the washer, each section being of semi-cylindrical configuration and designed for interfitting association with the other section. For this purpose each section has one end formed with a tongue 12 which is formed with a circular head portion 13, and both the tongue and head portion are bevelled on their opposite sides as at 15 for a purpose to be presently set forth. The other end of Serial No. 651,998.

each section is formed with a socket or re'- cess 16 shaped to conform to the configurz tion of the tongue and head, and the edges of this socket are grooved as at 18, the groove being substantially V-shaped to ac commodate the taper of the tongue and head. The sections are arranged end to end, with the tongue of one section being received by the groove of the other section in a manner so that the respective sections are interfitting and held associated without the use of additional fastening elements. This construction allows the washer to be easily assembled or disassembled, and makes it possible for either section, if worn, to be replaced by a new section at half the cost of a new washer.

lVhile it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described and that such changes may be resorted to when desired as fall within the scope of what is claimed.

Having thus described the invention, I claim:

A device of the character described comprising two complementary semi-circular plate sections, each of which is provided with a bifurcation at one end and a. recess at the inner end of the bifurcation, the opposed faces of the bifurcated parts and the walls of the recesses being formed with cou tinuous V-shaped in cross section grooves, a head carried by the opposite end of each of the sections having beveled edges adapted to be received in the grooves, and the bifurcated part being adapted to be bent into engagement with the head whereby to lock the two sections together.

In testimony whereof I affix my signature.
