Application led September 25, 1915. Serial No. 52,635.
To all whom t mag/concern.'
Be it known that I, JOHN M. MARTIN, citizen of the United States, residing at Oil City, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Drill- Chucks, of which the following is a specification.
The object, construction and operation of my improved drill chuck are herein Set forth with suflicient clearness to enable those skilled in the art to which it relates, to make and use the same.
The object of this invention is to provide a simple, efficient, cheap and easily-operated chuck for straight-shank drills, and which is adapted for use in a drillpress or like machine tool. The construction whereby 1 embody my invention and attain said objects is fully illustrated in the drawings, the various figures of which are as follows:
Figure 1 is an elevation of my improved chuck. Fig. 2 is an inverted plan view. Fig. 3 is a central, vertical section of the chuck-barrel, j aw-housing and cam-ring. Fig. 4 is a transverse section on line IV--IV of Fig. 3. Figs. 5, 6, 7, 8 and 9 are the various details which compose my chuck.
The construction here illustrated is as follows: A. taper shank 1 is provided upon its lower end with a screw-threaded portion 2, upon which is screwed a chuck-barrel 3. Said barrel is provided at its lower end with an opening 4, for the insertion of the shank of a drill; through the side wall of said barrel, in proximity to the lower end thereof, are provided two oppositely-positioned ports 5 for the reception of the jawtongues 6. Within saidl body, and positioned at the lower end thereof, are two jaws 7, the tongues 6 of which, project through said ports 5. Also positioned within said body is a jaw-housing 8, provided at its lower end with a vertically-extending slot 9, adapted for the reception of said jaws 7 the oiice of said slot is, to hold the jaws in their proper position and relative alinement and to guide them in their respective movements, also to relieve them of a larger portion of the strain due to turning the drill. Extending transversely across the upper end of said slot is a pin l0, which is for the purpose of limiting the inward movement of said jaws to the extent of a displacement of tongues 6 from their respective ports 5. For the purpose of producing the inward movement and clamping action of said jaws, I provide a clamping ring, 11, in the chamber of which is formed two oppositely-positioned cam-lugs 12, the inner face of each of which lugs is adapted to impinge upon the outer end of a tongue 6, of the respective jaw 7 which is adjacent thereto, whereby said jaw is caused to move inwardly against the shank 13 of a drill. Referring to Fig. 4, it will be readily understood that the clamping action of said ring will be produced by turning said ring in the direction indicated by the arrow. Said rmg 1s so constructed that if the same were raised so that the bottom wall comes into Contact with the lower face of said tongues 6, said ring may be held in a stationary position while the body revolves, and this permits the removal and insertion of a drill wlthout stopping the spindle of the drillpress, or other element of the machine in which the drill is used. 1n this case, it should be understood that said spindle, together with shank 1 and barrel 3 revolves in the direction opposite to that indicated by the arrow. The feature which makes possible this operation is the plain, concentric channel 14 in the lower portion of said cam-ring; when said ring is raised, so that the tongues 6 are positioned within said channel 14, they have a clear, unobstructed sweep throughout the full extent of said channel. non-actuative position of the clamping ring 11. By lowering said ring to the position This is what 1 term the shown in Fig. 3 the clamping action of the lugs 12 becomes effective, since they are then in the plane of the tongues, and actuate the same inwardly.
I claim the following:
A drill chuck comprising, in combination, a shank, a barrel secured to the lower end of said shank, there being an opening through the lower end of said barrel for the insertion of a drill-shank, also lateral ports in said barrel for the passage of jawtongues, jaws positioned within said barrel each provided with a tongue adapted to project through one of said ports, a housing within said barrel arranged to maintain the alinement of said jaws, and a verticallymovable clamping ring encircling said barrel having a plain, concentric chamber or channel whereby said ring is adapted to be placed in the non-actuative position, by said 'In testimony whereof I affix my signature vertical Inovernent,4 and also provided With in presence of two Witnesses. inwardly-extending clamping-lugs having concentric inner faces arranged tozimpinge JOHN M. MARTIN. 5 upon the outer ends of said tongues, Where- Witnesses:
by a clamping action is imparted to said GEORGE M. KINGSLEY,
