SPECIFICATION forming part of Letters Patent No. 350,952, dated October 19, 1886. Application filed May 91, 1585. Serial No. 166,235. (ModcL) To all whom it 77mg concern: served that the fixed shoulder on the shaft Beitknown that we, J. MORRIS OHILDs and may consist of a conical, square, or other DEWANE B.

It is obvious that the disk B may be made XV e rotate the stones by means of a shaft, A, to fit the shaft with substantial accuracy, and mounted on a frame, the shaft being provided an ordinary nut be used for clamping the stone with handle or crank F. between it and the fixed shoulder, without de- 5 For locking the stone to the shaft on which parting from the spirit of our invention, a1- it is mounted to be rotated we provide fixed though we prefer the tapering nut as the most shoulder a, Fig. 9.

more fully explained. It will here be 01)- 0, represents the ordinary crank for attaching a treadle, and a represent the bearings for receiving the crank or handle F.
I) b" represent boltholes in the clamping disk. We provide a truss frame for mounting this stone, having two horizontal beams, D D, supported at each end on truss-legs D D, which are formed, preferably, of iron, each pair of legs consisting of two pieces, (indicated in Fig. 3,) forming braces. Each set of legs are riveted at d, and are formed of two strips of iron, (1 and (1 These logs are braced to the beams by braces d d, one end attached to the beam at d d, and the opposite ends to the legs at (1 d as shownin Fig.l,thereby forming a reliable and compact frame easily packed for shipping. \Ve also provide an ordinary treadle, E, one end pivoted to the leg at e, and the center of said treadle connected by hook e to connectin -rod e which is attached to crank a, forming a device in general use.
f f represent strengthening lugs on the clamping-disk. These may be omitted at the option of the manufacturer.
What we claim as new, and desire to secure by Letters Patent, is r l. The combination of two disks, each disk having a central perforation, the retaining bolts for engaging and clamping the disk over the eye of the stone, the shaft with a fixed shoulder and a screw-threaded section, the locking device for engaging one of the disks and rigidly holding the shaft and stone, and the nut for retaining the stone and disk in contact with the fixed shoulder, substantially as described.
2. The combination,with thegrindstone and shaft,of the fixed shoulder provided with projecting flange and grooves, 21 centering and clamping disk with central opening with lugs projecting into said opening, corresponding in number and size to the grooves in the shoulder, a second clamping-disk with central aperture, the two disks held in the eye of the stone by bolts and nuts, and the tapering nut for fitting the central opening in one of the disks and working on the screw-threaded section on the shaft, substantially as described.
3. The combination, with the grindstone having a central eye, of two clamping-disks with central openings rigidly held on opposite sides of the stone over the eye by bolts and nuts, a locking device consisting of a fixed shoulder on the shaft with grooves and tongues for locking the shaft and disk, the tapering nut, and a screw-threaded section on the shaft,
substantially as described, for the purposes stated.
4. The combination of a fixed shoulder on the shaft, two perforated clamping-disks centered and bolted over the eye of the stone, a locking device consisting of afixed shoulder with grooves for receiving lugs in the opening of, one of the disks, a tapering nut for fitting one of the disks, and a screw-threaded section on the shaft for receiving the nut and hold ing the stone and disk in contact with the fixed shoulder.
5. The combination, in the frame, of two parallelbeams supported at each end on trusslegs, each set of legs formed of two bands of iron bent and riveted together,with braces attached to each set and to the parallel beams, substantially as described.
6. The combination of the perforated disk, the bolts and nuts for holding said disk to the stone, the fixed shoulder on the shaft, and means for locking the disk and shaft and holding the same in contact with the fixed shoulder.
In witness whereof we have aifixed our signatures in presence of two witnesses.
