Application ledFebruary 24,*1-916'.'l SerialNo. 80,224,

To all fwwmlz't may Qnccjrn l Beit"knownithat lF,'I`rioMAs J. FEGLEY, a citizen of the United States, residing 1n Philadelphia; Pennsylvania,- havev invented1 certain Improvements in Chucks, of `which dinal view, showing the shell in section; Fig.

3 is a longitudinal sectional view on the line a-a., Fig. 1; Fig. 4 is a view similar to Fig. 2 with the releasing device drawn back; Fig. 5 is a transverse sectional view on the line b-b, Fig. 2; Fig. 6 is a perspective view of the releasing device; Fig. 7 is an enlarged sectional view of the same; Fig. 8 is a view illustrating a modification of the releasing device; Fig. 9 is a perspective view of another modification of the releasing device; and Fig. 10 is a perspective view of the cross bar.

Referring to the drawings, 1 is the body of the chuck having an opening 2 in which is located the shank 3 of the bit 4. This bit may be 'a drill bit or a screw driver bit, or any type of bit desired. The bit has a notched end 5 fitting a recess 6 at the inner end of the opening 2 of the body portion 1 and has a notch 7 some distance from the end to receive a cross bar 8, which is adapted to an inclined way 9 in the body portion 1. Mounted on the body portion is a sleeve 11 having a slot 10 into which the cross bar eX- tends. The ends of the cross bar are turned down into the slot so as to hold it laterally A spring 12 is located between a shoulder 18 at the rear end of the chuck and the sleeve 11 so that when the sleeve is pushed back to force the bar 8 out of engagement with the notched bit the spring will yield, but the moment the spring is released the sleeve will be forced forward again, carrying with it the bar 8.

14 is the releasing device made in the form of a ring, as shown in Figs. 5 and 6,v

and encircles the body portion 1 in advance ofi` the sleeve1'1. rlhis releasing device has a fingen hold-` 15 which projectsfthroughla slot 20 in the shell 17. It will be noticed that the? shelll has an inturned` iiange 19` at its outerend which fits the body portion and a tapered sleeve 18 is forced onto the tapered end of the body portion and against the flange 19, holding the several parts in position. The releasing device is shaped as clearly shown in Fig. 7, being slightly bent to form a pivot point m which rests against the sleeve 11, while the lower portion of the releasing device rests against the inner side of the flange 19 so that on forcing the releasing device toward the rear, as in Fig. 4, the sleeve 11 is pushed back, carrying with it the cross bar 8 and, as the way 9 in the body portion is inclined, it will force the bar 8 out of engagement with the bit, but as soon as the device 14 is released the spring 12 will return the parts to their first position. By this construction the shell of the chuck can be handled without the liability of releasing the bit.

In some instances, instead of making the releasing device curved, as in Fig. 7, it may have a bearing point formed thereon, as in Fig. 8, and in some cases it may be perfectly flat without departing from the essential features of the invention.

. In Fig. 9, I have shown a construction in which there are two finger holds 151L so that in this case the releasing device 14?t is made flat and can be bodily moved to the rear to release the bit.

I claim:

1. VThe combination in a chuck, of a body portion having an opening therein and having a notched bit, said body portion having an inclined way; a bearing located in the way; a sleeve mounted on the body portion and slotted to receive the ends of the bar; and a releasing device in the form of a rocking ring having one bearing against the forward end of the sleeve and another bearing against the shell and arranged to be turned to cause the sleeve to move the bar in the way.

2. The combination in a chuck, of a body portion having an opening therein for a notched bit, said body portion having an inclined way; a sleeve mounted on the body portion; a spring back of the sleeve, said sleeve having a slot; a cross bar extending through the inclined way and into the slot of the sleeve; a releasing device in the form of a ring having a projecting finger hold; and

a shell having a slot through Which the iinger hold extends so that on pushing the iin- 5 ger hold toward the rear of the chuck the bit will be released.

3. The combination in a chuck, of a body portion having an opening to receive a notched bit and having an inclined Way therein; a bar located in the Way and arranged to extend into the notch of the bit; a sleeve mounted on the body portion and slotted to receive the ends of" the har; a spring tending to force the sleeve forward; a releasing device in the forni of a ring having a projecting portion; and a shell through which the projecting portion eX- tends, the shell having a bearing point and the releasing device bearing against the sleeve at the center so that when the releasing device is retracted it will move the sleeve to withdraw the bar from engagement With the bit.
