To all 'whom tm/ty con/cern.-

Be it known that l, GEORGE H. BEsT, a subject of Great Britain, residing at Hampton, in the county of Kings and Province of New Brunswick, Canada, have invented new and useful Improvements inl Set-Rings, .of which the following is a specification.

This invention relates to improvements in set-rings or -collars,f and the objects of the improvements are to provide for the placing of a set-ring upon any shaft,'for the purpose of taking up end play, or for any other purpose, withoutremoving the shaft or either end of it from its bearings. j

A further object is to provide a set-ring which may be rmly affixed toa shaft without the useof set-screws or bolts or similar` appliances, the rin@r when attached having a rimV entirely free from projecting set-screw heads or other projections, thus avoiding the danger to workmen consequent upon the liability of their clothing to catch upon or become entangled by such projections. i

'Fliese objects-are obtained by the mechanisn; illustrated in the accompanying drawings, in which y Figure 1 is an internal side view of one.- half or art of one of the sections of the setring. ig. 2 is an external side view of the other half of said section. spective view of both halves or parts assembled. Fig. 'Li is a vertical section thereof. Fig. 5 is an external side view of one-half or part of the other section ofthe set-ring. Fig. 6 is an internal side view of the other half of said section. Fig. 7 is a view in perspective of the halves of said section partly assembled showing the manner in which they are jointed or fastened together. Fig. 8 is a vertical section thereof. Fig. 9 is a side view of a shaft with both sections of the set-ring thereon and partly screwed together. Fig. 10 is a similar view showing the set-ring sections completely screwed together and in final position on the shaft. Fig. 11 is a section on Referring s eciflcally to the drawing, the set-ring or col ar is in two sections indicated at 15 and 16respectively. The section 15 has an opening 17 for the shaft 18, and on one ide a threads also extends. The sleeve screws into a tapernig and threaded bore 26 in the section 16.

Fig. 3 is a perrejecting externally-tapering and. ci) sleeve 19 through which the shaft Both sections are split or halved so that they can be placed on the shaft without removing the latter from its bearings. The two'halves of the section 15 are indicated at 21 and 22, respectively, and on one side thereof are grooves or' channels'23, which when the halves are placed together, form an annular groove-or channel. the section 16 are indicated at 24 and 25, respectively, and on one side thereof are shoulders 26, which when said halves are placed together, form an annular shoulder. Vhen the sections 15 and 16 are assembled on the yshaft the shoulders 26 enter the grooves 23.

The 'sleeve 19 is rendered reiiexible by making longitudinal saw cuts or 'kerfs 27 therein so that when said sleeve is screwed into the bore`20 it will be forced against the shaft totightly grip the same.

The parts 24 and 25 are fastened together' by a dovetail joint, they being lprovided at their meeting ends with dovetail tenons 28 and mortises 29, the tenon of one of the parts entering the niortiselin the other part, whereby they will be securely fastened together on the shaft.

' lo place the ring on the shaft, the parts 24 and 25. are placed on the shaft from opposite sides'thereof and slid lengthwise thereon to- Ward each other and interlocked` by sliding the tenons 28 into the Inortises 29. The

parts 21 and 22 are then placed to ether'on.

the shaft fromop'posite sides thereo and the sleeve 19 inserted into the bore 20 and The two halves of screwedtogethenwhereby the ring'will be y securely fastened on the shaft. Eachring section has holes 30 for a Spanner or lother suitable tool for screwing the parts together.

l/Vhen the ring is secured to the shaft as herein described, there are no screw-heads or other projections extending beyond the periphery. of the ring. The ring, maybe made of any size to fit any sized shaft. 'l

The obj ect in breaking the joint by having `the shoulders26 engage with the grooves 23 is that insome cases the ring might be securely affixed to the shaft and screwed up as tightly as it would go, and yet the two sections of the ring might not come absolutely together. In such a case' the joint herein described would prevent anything from eet- IOO ting between the W0 Se@ as o the ring and said gros@ 5 there being means im 'neming becoming enmged on thm-amis of the *UE 'e nutecbions together. seeve,
