`J. S. WARNER, OF vOGDENSBURGr, NEW YORK.
.Letters Patent No. 98,820, dated January 11, 1870.
IMPROVED CHUCK FOR GRINDING- CRYSTALS.
l The Schedule referred to in these Letters Patent and making part of the same.
To all 'whom it may concern i Be it known that I, J. S. WARNER, of Ogdensburg,
' in the county of St. Lawrence, and State of New York,
be attached to the lathe-mandrel at the base, andl provided with a face-plate, capable of being readily attached to the edge, or the part resembling the top of .the cup, or detached therefrom. The face of `the crystal .is ground against the side of this plate, using emery and oil, and holding it, by rst attaching it to a stick, by sealing-wax, orvotherwise, and when the face is suiliciently ground, the plate is removed, and the edge finished inside the cup-shaped part.
' Figure l is a sectional elevation ot' the cup-shaped part, which is attached to the mandrel;
Figure 2 is a front elevation'f the same; Figure 3' is a side elevation ofthe face-plate; and Figurel 4 is a section of both attached together. Similar letters of reference indicate corresponding parts.
A is lthe cup-shaped part, having a conical space,
B, of sufficient diameter and depth to receive the largest`or smallest crystals, and to act, by its inner wall, on the edges, to reduce and finish them, emery and oil being used, and the crystals being held on sticks,`to which they are attached by sealing-wax or.
other suitable means. This cup A is attached, at the centre ot' the base C, to the mandrel ofa lathe, or other rotary spindle, to be rotated when the crystals are presented to it, as above. Y
D isthe faceplate, adapted for attachment to the part A, at the open end, and for grinding the faces of the edges of' the crystals, by holding them against the front thereof, oil and emery being used in like manner. The crystals commonly require to be ground in both these ways in fitting, and it is important to be able to -change readily from the one to the other.
For this purpose, I have provided a flange, E, on the face-plate, which ts a short cylindrical part, F, ofthe cup, and has two radial pins G, which, together with the right-angular notches H in the edge of the cup, form bayonet connections, by which the two parts may be readily connected or disconnected.
' Having thus 'described my invention,
I claim as new, and desire to secure -by Letters Patentj A crystal -grinding chuck, composed of the cupshaped part Aand face-plate or disk D, the cup being arranged t'or attachment to the mandrel, and the disk detachably connected to the cup, all substantially as specified.
The abovel specification of my invention signed by me, this 27th day of November, 1869. A
` t J. S. WARNER. Witnesses:
GEO. W. MABEE, ALELF. ROBERTS.
