CHUCK-JAW.

7 Application filed December 9, 1902} Serial No. 134,531. (No model.)
To all whom it maycoltcern: found on various kinds of machine tools,
Be it known that I, EDWARD P. BULLARD, particularly drills, lathes, boring-mills,&c. a citizen of the United States, and a resident This table, as is usual, is provided with a of Bridgeport, in the county of Fairfield and series of radially arranged grooves 13, in
State of Connecticut, have invented certain which various forms of tools are designed to 55 new and useful Improvements in Chuckbe secured, and are especially adapted for Jaws, of which the following isaspecification. gripping-jaws such as my invention com- This invention relates tonewand useful irnprises. The majority of clamping-jaws of provements in chuck-jaws such as are extenthis class now found upon the market are pro- 1o sively used on drills, lathes, boring-mills, &c. vided with a screw which sets out from the 60 It is the object of my invention to improve rear end in a manner to operate the jaw as upon jaws of the above class in several imdesired. This form of device is objectionportant particulars, the first of which is to able for two reasons, one being the fact that provide a jaw which will grip and hold an itnecessarily sets up high above the table article firmer than those now in use; second, and likewise projects out far from the outer 65 to construct said jaw in a way that the entire end, thus being objectionable, for the reason load will not come entirely against the clampthat'it is very much in the way. Further, ing-screw, but may be deflected against the such a construction is weak and quickly gives ways in which the jaw is mounted; third, to way under the severe usage that it gets.
so arrange the device that the adjusting My invention may be attached to any of 70 screw will not set up against thejaw and prothe usual forms of machine-tables and reject therefrom, but will be arranged to one quires no special construction other than that side below the plane of the jaw and at an usually found. It comprises an attachable angle thereto other than a right angle to the portable base C to fit upon the face of maline of movement of the jaw, thus making chine-tables and is provided with one or more 75 the article more compact and requiring less ways D to engage the beforementioned space upon the table, all of which are very grooves B of said table. This base is proimportant features. vided with bolts F for its attachment to the With the above objects in view my inventable, which bolts pass through the holes E 0 tion resides and consists in the novel conof said bed and engage the shoulders ofythe 8o struction and arrangement of parts shown grooves B in the usual way. This base is upon the accompanying sheet of drawings, -further provided with a way G, having lonforming a part of this specification, upon gitudinal ribs H in its side walls, the whole which similar letters of reference denote like adapted to receive the jaw I, which is sur- 5 or corresponding parts throughout the sevfacedto fit said ways and ribs in amanner 8 eral figures, and of which-- to allowthejaw to slide longitudinally there- Figure 1 shows a perspective view of a borin, but at the same time retain it in engageing-mill table detached with a series of four of ment with the adj ustingscre w, as will later myimproved clamping-jaws attached thereto be explained. The jaw proper contains the 40 and ready for use. Fig. 2 is a plan view of usual gripping-surfaces J and is further pro- 90 my improved clamping-jaw detached. Fig. vided with a diagonally-arranged toothed 3 is a longitudinal vertical section taken on bottom surface K, as will be seen in dotted line 3 3 of Fig. 2 and is designed to illuslines in Fig. 2. At a right angle to the face trate the connection between the screw and of these teeth and diagonally through the jaw. Fig. 4 is an end view as seen from the lower portion of the base is arranged a bore 5 left ofFig. 2.. Fig. dis a similar-end view of L, the ends of which are inclosed by caps M,

Owing to the great number of threads in the screw and teeth in the jaw for engaging the screw, a very strong and reliable engagement is had between the parts, thus being equal to any-strain that is brought to bear.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
1. Inadevice of the class described,thecombination'Wit-h a portable base having means of attachment to a table, of a jaw mounted therein and containing diagonal teeth on its under side,- a bore arranged diagonally with reference to the line of movement of jaw through the base, an adjusting-screw mounted in said bore in engagement with the teeth of the jaw for operating the latter, said screw extending through the base with exposed engaging heads on either end.
2. Inadeviceoftheclassdescribed,thecombination with a portable base, of means for its attachment to a machine, a jaw mounted in said base bearing teeth on its under side, a bore through the base, bearing-caps inclosing either end of said bore, a screw mounted in said bearing-caps to engage the jaw, and heads on either end of the screw for adjusting the same.
Signed at Bridgeport, in the county of Fairfield and State of Connecticut, this 1st day of December, A. D. 1902.
