E. P. ALSTED RING WHEEL CHUCK May 24 1923 Filed Patented July 29, 1924.
TATES PATENT oFFicE;
EDWARD r; ALsrEnor TRUESDELL, WISCONSIN.
RING-WHEEL CHUCK.
Application filed May 24, 1923.
To all whom it may concern:
Be it known that I, EDWARD 'P. ALs'rEn, a citizen of the United States, and resident of Truesdell, in the county of Kenosha and State of Wisconsin, have invented new and useful Improvements in Ring-Wheel Chucks, of which the following is a descripplurality of gripping leaves or sections designed to firmly secure in place the ring wheel, these leaves having arranged in cooperative relation therewith, a retaining ring, recessed adjacent each of the movable leaves, with means for retracting the movable leaves, whereupon the removal or adjustment of the ring wheel will be facilitated. V
The details of this improved invention will be made more apparent as this description proceeds, especially when considered 1n c011- nection with the accompanying drawings, wherein;
Figure 1 is a front elevation of a ring wheel chuck constructed in accordance with this invention; and,
Fig. 2 is a section view, taken substantially on the plane indicated by the line 22 in Fig. 1.
Referring more particularly to the draw ings, wherein like reference characters indicate like parts, it will be noted that there is provided a shell or body made preferably of one piece, the shell body at the center thereof being formed with a cupshaped ofl set 1.1, adapted to receive the spindle collar, (not shown), thus reducing the overhang to a minimum.
The rim of the shell is formed with a plurality of slots 12, thus providing a plurality of leaves or sections. Alternate leaves 'or sections 13 are secured by rivets 1 1, or otherwise, to a retaining ring 15. The remaining alternate leaves 16 are movable relative to the ring 15, this being made possible by forming the ring 15 with a plurality of recesses or cut-away portions 17, arranged adjacent the movable leaves 16, as clearly illustrated in Fig. 1.
Serial No. 641,277.
Engaging each movable leaf 16 is a set.
screw 18, these set screws passing through the ring 15, whereby the movable leaves may be forcibly moved toward the ring 15, into the recesses 17. Set screws 19, threaded through the ring 15, are provided, which en "a e the movable leaves for forcin them into engagement with the abrasive ring wheel 20. The ends of the set screws 19 abut the movable leaves so that by rotate ing the set screws19 properly, these mov-v able leaves may be forced away from the ring 15 and into engagement with the wheel 20. Y r
' For adjusting the ring wheel axially of the chuck, there is provided a backing;
plate 21, centrally apertured, as at 22, to clear the cup-shaped off set 11 of the chuck. Bolts 23, threaded through the backing plate, engage the back of the chuck 10, thereby forming adjust-able stops for positioning the back plate 21 with reference to the chuck. Lock nuts 24; are provided for locking the bolts 23 in their adjusted positionsm} When the abrasive wheel becomes worn down to the face of the chuck, the same may be adjusted axially of the chuck in the following manner.
The set screws 19 are first backed out and the screws 18 are actuated to draw the movable leaves 16 into the recesses 17. This releases the abrasive wheel 20. The abrasive wheel may then be adjusted relatively to the chuck, so that a portion of the same will project beyond the face of the retaining ring. Thebacking plate 21 may then be adjusted by suitably manipulating the bolts 23 and the lock nut- 24, whereupon the leaves may be forcibly retracted into the adjacent recesses of the retaining ring, thus disposing them on a greater diameter than that of the stationary or fixed leaves. Thus the abrasive wheel is completely released, enabling the same to be easily removed from the chuck or adjusted relatively thereto, without liability of the same becoming stuck.
Reservation is made to make such modifications in the specific form of the invention illustrated as may come within the purview of the accompanying claims.
Having thus described the invention, what is claimed is:
1. In a' ring wheel chuck a shell body formed with peripheral slots providing a pluralityo'f leaves, a retaining ring recessed adjacent said leaves and means for moving said leaves into said recesses for releasing a ring wheel adapted to be secured thereby.
2. In a ring wheel chuck a shell-like body peripherally slotted to form a plurality of leaves, a retaining ring engaging said leaves and recessed to permit a radial displacement of said leaves and means for forcibly moving said leaves into said recesses whereby a ring wheel adapted to be engaged thereby maybe released.
3. In a ring wheel chuck a shell-like body peripherally slotted to form a plurality of ring Wheel retaining leaves, a ring wheel adapted to be gripped by said leaves, a retainin rin surroundin said leaves and,
b r provided with a plurality of spaced recesses arranged adjacent alternate leaves and means for forcibly dra'wm'g saidalternate leavesinto said recesses,'f0r the purpose described.
4%. In a ring wheel chuck a shelllike.body "formed with a plurality of spaced slots throughout its rim forming ring retaining leaves an abrasive rin ada ted to be S11)- I a u ported by said leaves, a retaining ring surrounding sald leaves, said rlng being formed with a plurality of spaced recesses arranged adjacent alternate leaves, means carried by having its rim slotted to form a plurality of abrasive Wheel retaining leaves, an abrasive wheel adapted to be gripped by said leaves, a retaining ring surrounding said leaves, means carried by said ring engaging said leaves for increasing the diameter of selected ones of said leaves and an adjustable backing plate engaging said abrasive Wheel.
6. In a ring wheel chuck a shell-like body having its rim slotted to form a plurality of abrasive wheel retaining leaves, an abrasive wheel adapted to be gripped by said leaves, a retaining ring surrounding said leaves, means carried by said ring engaging said leaves for increasing the diameter of selected ones of said leaves, a backing plate engaging said abrasive wheel and bolts provided with lock nuts passing through said plate and engaging said shelllike body for adjusting said back plate to axially adjust said abrasive wheel.
In testimony whereof, I afliX my signature.
