1 Claim. Cl.l 145-50) My invention relates to drivers for socketedv screws.

It has among its objects to provide an improved driver for a socketed screw of the construction described and claimed in my copending application, Serial No. 275,902, filed May 26, 5 centutes intersecting along a line l which, as 1939, now Patent No. 2,285,460, of which this apappears in Fig. 4, is convex. The intersection plication is a division. A further object is to line 'l forms angles with the vertical axis of the provide such an improved driver whereby it is socket which become progressively more acute made possible to connect the screw and driver toward and to the bottom of the socket.

Referring to the socket 2, it will be seenthat While I have in this application specifically it is provided with a series of radially disposed described certain forms which my invention may flutes 4. Each of these has an end surface 5a assume ln practice, it will be understood that which, as appears in Fig. 2, is convex, the verthese forms of the same have been shown for tical angle of the surface with respect to the axis of the socket becoming progressively more acute toward 'and to the bottom of the socket. Each flute is also provided with laterally concave side surfaces 6, the adjacent side surfaces of adjaaxis of the driver which become more acute progressively toward and to the lower end of the bit, the extreme lower end of said bit having an area larger than that of the floor of the socket and said abutments being cut back for a predetermined distance in the zone located in the entrance to the mouth of the socket so as to limit the binding of said outer surfaces of the abutments with corresponding parts in the socket to a region spaced upwardly from the bottom of the socket and downwardly from the top of the socket.
