cauox FOR GRIFFING THE INNER AND THE OUTER PERIPHERY OF HOLLOW ARTICLES Filed June 27, 1955 In venlar J/ephan BrUc/r Allbrrzeys Patented Mar. 20, 1934 CHUCK FOR GRIPPING THE INNER AND THE OUTER PERIPHERY OF HOLLOW ARTICLES Stephan Briick, Berlin, Germany Application June 27, 1933, Serial No. 677,921
In Germany June 6, 1932 1 Claim. (Cl. 279-33) This invention relates to an improvement in or modification of the chuck for gripping or clamping hollow articles claimed in my corresponding application Serial No. 608,106 filed April 28, 1932 (Patent No. 1,912,251, May 30, 1933) and 5 it refers to a chuck, which grips both the inner and the outer periphery of the hollow articles. For this purpose the clamps are provided with shoulders having inner gripping faces, which allow external clamping.
The invention is illustrated byway of exemplification in the enclosed drawing; it signifies:
Fig. 1 is a side-view of the chuck, partly in section,
Fig. 2 is a view seen from A, that is in the direction of the center line against the front face, Fig. 3 a section right angular to the centre line through the mounting of the clamps.
The gripping device consists of the three clamps a a and a pivotally mounted in the head I). This head may be supplied in the general way with a thread or flange for fixing in the spindle head of the lath or with a simple bore for the reception of a shaft end.
The three clamps, which are equally shaped, are characterized by the following three faces: one cylindrical face k, a threaded gripping face 0 and two equally shaped faces d. The three clamps are arranged with their said cylinder-faces k:
rolls upon the two others and always around the axis of its cylinder face. The clamps, which touch each other, are mounted for oscillation by means of the cylindrical pivots e in the head I). By means of the ring shaped springs i, which are fastened on the one end by the screw 9 to the head b and on the other one by the pin it to the pivot e, the clamps are turned in the direction of the arrow 12*. By so turning the three clamps in the direction of the arrow 12* the diameter of the circle, on the circumference of which the eccentrically arranged gripping-faces are locata way, that they pivot in the direction of the arrow p The operation of the device is the same as in the copending application; By slightly turning the work-piece the latter is" pushed between the clamping faces m of the shoulders 1 -1 In releasing the clamping faces m are pressed against the work-piece by force of the springs. When cutting with the tool the work-piece drags the clamps along in the direction of the arrow 11 This way the clamping faces-are pressed inwards, with the effect, that with the increasing cutting pressure the work piece is pressed into the clamps at the same ratio.
What I claim is:
A chuck for gripping the inner and the outer periphery of hollow articles comprising a chuck body, three gripping clamps mounted for oscillation in said chuck body and subjected to the infiuence of springs, resisting or compelling oscillation, these clamps having cylindrical faces, rolling on each other, cylindrical centering faces, touching each other, faces for gripping the inner periphcry of articles and shoulders, connected to the gripping clamps and having faces for gripping the outer periphery of hollow articles, both of the gripping faces being eccentric'with each clamp member.
