' when the two are coupled together or when 'be held from rotation with the bearing external part of the bushing 5 which is of g engage against the outside of one of said e5 greater diameter than that to which the nut i 12 is connected. The chamber presented hy said cup-like part 15 incloses the cap nut 12 and the `locking nut 14. The cup-like part 15 has connected therewith a cock as 16 byop'ening the valve or equivalent part in which water will be caused to flow into said cup-like part and from thence into the open rear end of the quill-section 3. Owing to the presence of the nuts 12, and 14 and the parts associated therewith it is not possible for water to pass around said quill section 3. The stuihng ocx members 9, 10 and 11 may sleeve 13 by means of a pin as 17 extending radially of the bushing 5 and engaging the member 9.

The front quill section 4 may be inclosed in a sleeve as 18 or a sleeve as 19 theronly difference between the two sleeves being eX- ternal to adapt the sleeve 18 for a larger tool than the sleeve 1'9, the latter for such purpose being made of two external diameters. I will now describe in detail the parts carried by the sleeve 18 such description applying exactly to the sleeve 19, and such parts of course include the quill section 4. The quill section 4 is of course bored to register .with the bore in the quill section 3 they are in operative communication and is provided with a socket as 20 to closely receive the tip or outer end of the quill section 3. Thetwo quill sections are shown as connected in Fig. 3.

The quill section 4 is provided at its inner end with clutch teeth as 21 to engage similar teeth as 22 on the sleeve or hollow shaft 7 at the time when the quill section 3 is fitted in the socket 2O of the quill section 4 as shown in Fig. 3. This provides for a Water tight connection between the two quill sections and for a 'driving'. or power transferring connection between the sleeve or hollow shaft 7 and quill-section 4.

When the quill-sections 3 and 4 and' when the quill-section 4 andthe hollow shaft 7 are connected in the manner set forth the sleeve 18 is fitted in the hollow bearing 2, j

the relation being a removable one so that for example the sleeve with its attached parts can be dismounted and the sleeve 19 with its attached parts can be put in its place, this being for the pm'pose of changingrl i tools. When this change is made the drivl ing mechanism and the water supply are af ectcd in nowise.

The means provided for removably holding the sleeves-18 or 19 in place is best shown in liig. 4 and comprises coperating jaws as 23 and 24 made in the form of tubes, fitted in a'transverse opening in the bearing 2 and encircling a bolt as 25 headed at one end to l jaws as the l jaw 23 and having a handoperable nut as 26 to engage against ,the jaw 24. The working portions ot the jaws 23 and 24 are made on arcs concentric with the periphery of the sleeve 18. 1t will be clear that when the nut 2G is turned in the proper direction the two jaws 23 and 24 are caused to relatively approach so as to bind lirmly on the circumference of the sleeve 18 fitted in the bearing 2. By unscrewing the nut 26 the pressure on the sleeve 18` can be relieved to effect the withdrawal of said sleeve 18 and the introduction of the sleeve 19 or some other sleeve. Each of the sleeves is shouldered or peripherally flanged as at 13 and 19 respectively to bear solidly against the bearing 2 when the described connections are made. j

Upon thel quill section 4 externallyl and near the inner end thereof I have represented a double bearing cone 27 the cone-faces of which bear against the adjacent ends of bearing sleeves as 28 fitted in an enlarged hollow portion of the sleeve 18 or sleeve 19 and held in place b screws as 29 whereby adjustability of sai sleeves 28 is provided for so that either or both of them can be caused to move inward, that is toward each other, to compensate for Wear.

l may if desired set int-o a conical o ening in the'outer portion of the sleeve 18 or 19) a split conebearing as 30, the outer cone sur. face of said bearing resting against the correspondingly formed portion 'of the sleeve 18 (or 19) While the inner cylindrical part of which receives for rotation, the quill section 4. The cone bearing 30 is held in place in the sleeve 18 (or 19) by a nut as 31 therein and which may be readily manipulated to take up wear in said bearing 30.

The tool is denotedby 32 and it is represented as' consisting of a grinding disk having a central opening to receive the extreme outer end of the quill-section 4. The disk 32 may he of different diameters, a disk of onev diameter being associated with a sleeve as 18 while a disk of a di'erent diameter will be associated with a sleeve as 19.

The disk 32 is caused to bind solidly against a thimble as 33 by means of a washer as 34 and screw 35, the serewbeiu'g tapped into the outer end of the quill-section 3 and forcing the Washer 35 firmly against the disk or wheel 32 and the latter"'against the thimble 31. The latter serves as an effective guard to prevent dust, particles ground 'off the work, and other foreign matter entering The body of .the

the lsleeve 18 (or 19). thimble 33 incloses the outer portion of the sleeve 18 (or .19) Ifor the purpose indicated. The opposite faces of the head of the thimble 33 and the washer 34 are provided-with channels or gutters as 33 for the escape of nels.

Water used in grinding While the quill-section 4 has a discharge port or outlet as 36 to supply the water fromthe quill directly to the grinding wheel 32 by Way of said chan- It will be appa-rent that it is a simple matter to remove a sleeve as 18 and its adjuncts from its supporting member and to put the sleeve 19 in its place. 'When either of said sleeves is in position there will be supplied to the grinding tool an adequate amount of j water without waste o r without injurious effect to any ofthe bearing parts. The quillsection 4 next the grinding tool is thoroughly protected from floating particles of all kinds so that wear from this cause is eliminated.
