Description

dldi %iaire GEORGE o. DUGKLEY, orNnw BEDFORD, MASSACHUSETTS;

Letters Patent No. 112,119, dated February 28, 1871.

IMPROVEMENT IN SELF-CENTERING CHUCKS FOR LATHES.

The Schedule referred to in these Letters Patentv and making part of the same.

To all persons to whom these presents may come yBe it known that I, GEORGE O. B'UcKnnY, of N ew Bedford,.of the county of Bristol and State of Massachusetts, have Vinvented a new and useful Self-Oentering Chuck for Lathes and dovhereby declare the same to befnlly described in the following specification and 'represented in the accompanying drawing making part thereof.

Of such drawing- Figure l is a side elevation;

Figure 2, afront-endl view;

Figure 3, a longitudinal section; and

Figure 4, a transverse section `ot' one of my-said chucks. I Y Y Figure 5 is a front-end view of it as itappears with its cap-plate removed from the jawcarrier.

In such drawing- A A A denote three jaws arranged' radially from a common center or axis, and within a carrier orv cyl indrical block, B, such being so as tol admit of each jaw being moved in a radial direction toward and from the axis of the block, there beingwithin the .block a central aperture, a. l

In the rear part of the block or jaw-carrier is a female screw, b, for the purpose of fixing the chuck upon the arbor of a lathe.. y f Each of the jaws has its outer edge shaped as two inclined planes, c d, which decline in opposite directions from the middle of the jaw.

Furthermore, there rests against inclined planes of each jaw two wedges, C C, arranged therewith, in manner as represented, and projecting beyond the jawcarrier, the wedges being disposed within the radial chambers or slits d for the reception of the jaws.

Enoompassing the series of wedges and jaws is af screws, G and H, cut on the next adjacentledges of the wedges, thearrangement ofsueh screws and wedges being as represented.

Furthermore, each jaw is dovetailed to its two wedges, in manner as shown, at h, or so connectedv therewithas to be moved radially of the block in onedireotion or the other by such wedges, while they may be in the act ot' being moved either toward or away from each other by these screwsand'oollar while the latter may be in the act of being revolved.

Eaohof the wedges, c, is also douetailed within the jaw-rarrier, as shown at i t.

Figure 6 denotes an end view; and

Figure 7, a side view of one' oi' thejaws;

Figure 8A being a side view; and

Figure 9, an end view of one of the wedges.

Figure 10 is a longitudinal section and .Figure 11, a front-end view oi the jaw-carrier. Figure 12 is a section of the collar representing its right-and-left screws.

By revolving the collar D the two wedges of each pair will be simultaneously moved in' opposite directions rectilinearly, and by being supported so that they cannot move radially, and by being dovetailed to the jaw they will cause the jaw to have a lateral or radial movement. 4

All the jaws may thus simultaneously be moved either toward oraway from the axis of the carrier,-

and thereby be clamped upon an article or unclamped from it, as occasion may require.

I am aware of the lathe-chuck described in the United States Patent N o. 48,259,1and make no claim thereto.

I therefore claimlhe jaw-carrier or centerblock B, the rotary sleeve or collar D, the wedges C, and the jaws'A, constructed, arranged, and combined as described and represented, the whole constituting a self-centering lathe-chuck.

' l GEO. O. BUOKLEY.
