JOHN J. STEIGER, OF PEORIA, ILLINOIS.
IMPROVEMENT IN EMERV-WHEEL HOLDERS.
Specification forming part of Letters Patent No. 184,306, dated November 14, 1876; application filed J une 24, 1876.
To all whom it may concern:
Be it known that I, JoHN J. STEIGER, of Peoria, Illinois, have invented certain new and useful Improvements in Safety Devices or Chucks for Emery-Wheels or Grindstones, for keeping emery-wheels or grindstones from bursting when revolving, and gaging them properly when worn down.
I do hereby declare that the following is a full, clear, and exact description of the same, reference beinghad to the accompanying drawings, and to the letters and figures of reference marked thereon, making a part of this specification.
The object of my invention is to so construct a device in such a manner as to prevent emery-wheels and grindstones from bursting when revolving, and to push the stone out, when worn off, by set-screws, so that it may be properly gaged for grinding purposes, and to hold them securely in position.
Figure 1 represents the face view of the safety device or chuck as it appears when ready for operation. Fig. 2 represents the rear view of the chuck with set-screws. Fig. 3 represents the beveled ring, which may be of one or more parts. Fig. 4. represents the follower-plate, which operates inside of the disks A, as shown by A in Figs. 1, 2, and 5. Fig. 5 represents a sectional view of chuck combined half-cut.
. The follower Bin Fig. 4 goes inside the disk A in Figs. 1, 2, and 5. The disk A on inside is beveled. The emery-wheel or grindstone, as shown by D in Fig. 1, is then put in the disk A. Around the emery-wheel or grindstone the beveled ring 0 in Fig. 3 is placed, and made to fit the beveled disk A. The setscrews in Figs. 2 and 5 marked f may have shoulders or not, and after passing through the disk A their ends strike against the follower B, as in Fig. 4, and when screwed up, after the set-screws c are loosened, push the emery-wheel or grindstone out for gaging purposes. Then the set-screws c are tightened by screwing them up, which brings the beveled ring 0 in Fig. 3 to fit into the beveled disk A, contracting it so that it fits tightly and closely around. the emery-wheel or grindstone, and holds it securely in its position. The set-screws b in Fig. 2 can be made with a shoulder at their ends, so that their ends may pass just through the follower at bin Fig. 4; or their ends may strike against the follower B without passing through the follower B at all. The set-screws a pass through the holes indicated by c in Fig. 4, and into the threaded holes 0 in Fig. 3. A in Fig. 5 is the disk, sectional view half-cut. B in Fig. 5 represents half-cut sectional view of the follower. O in Fig. 5 represents half -cut sectional view of beveled ring. D represents emery-wheel or grindstone half-cut sectional view, all combined for uses and purposes set forthf (J in Fig. 1 represents beveled ring to fit in disk A inside beveled, for uses and purposes set forth. 0 in Fig. 1 represents threaded holes for set screws 0, for uses and purposes set forth. E in Fig. 2 represents hole for axle of the device or chuck. The beveled ring 0 in. Fig. 3 may be made of one or more parts.
Having described my invention, whatI claim as my invention is the following:
1. A hollow disk, A, having its inner edge beveled away, in combination with the ring 0 and adjusting-screws or other similar devices 0, the ring 0 being made in one or more parts, and adapted to fit the bevel of the disk A, substantially as shown.
2. The combination of the followerB and suitable adjusting devices f, for regulating the emery-wheel, substantially as described.
