IMPROVEMENT IN DRILL-CHUCKS.
Specification forming part of Letters Patent No. 150,672, datedv May 1'2, 12:74; application led Aprn 21, 1874.
To all whom it may concern: j
Be it known that I, GEORGE D. BELGEEE, of Springfield, Massachusetts, have invented a Drill-Chuck, of which the following is a specification The object of my invention is to make what is commonly known as a drill-chuck in a more simple and effective manner than has been heretofore known.
Figure 1 is a transverse section when the parts are all together. b b is the main sleeve,
' to which all other partsare connected.
Fig. 4 shows the outer end in-section more fully. a is a-cap slipping over the end of the sleeve b, and is screwed fast to it at 2. B is the stock to which the sleeve'b is screwed, and the sleeve b is made to traverse out and back by engaging with the screw-thread on B at 3, Vthe stock B being attached to the lathespindle in the usual way, z' representing the sockethole.
Fig. 2 is a cross-section or end view with the cap a left off, giving an end view'of the jaws s s when ready for use. g is an expanding spring, by preference passing through holes in the jaws shown in Fig. 7 The duty of this spring is to press the jaws outward. The annular groove n is to hold the spring `g in its proper place.
Fig. 3 shows in perspective the wedge device, consisting of three wedge-shaped arms, s s s, rising up from the same base r. This base and arms, by preference, are made solid, though the arms may be pivoted or hinged to the' base r, and any required number of the wedge-shaped arms may rest on the base r. This base is pivoted to the inner end of the stock B, as shown by the pivot or tap-screwf.
Fig. 5 shows the sliding contact of the jaws c and the wedge-shaped arms s, the latter moving longitudinally outward, as shown by the arrow, driving the jaws c toward the center simultaneously.
Fig. 6 is an end view, and Fi g. 7 a side view, of one of thejaws.
Fig. 8 is the partition or diaphragm y y in the sleeve b, through the openings oc oc of which the wedge shaped arms pass, the openings forming guides for the arms s.
To adjust the opening or closing of the jaws c it will be seen that it is only necessary to screw the sleeve b to the right or leftover the stock B.
I clairn'as my invention- 1. The combination, as shown and described,
, of the stock B, swiveled wedge-piece o" s, and
jaws c, for the purposes set forth.
2. The combination, as shown and described, of the stock B, swiveled wedge-piece r s, jaws c, and annular springg, for the purpose set forth.
3. The combination, as shown and described, of the stock B, sleeve b, cap a, swiveled wedgepiece r s, jaws c, and spring g,- for the purpose set forth.
GEORGE n. BELcHEE.
