Be it knownrthatl, JAMES M.LAwLoR, a citizen of the United States,resicing Vat ToT eka, in the 'county ot Shawnee and'State ot' invention, such. as will venable Vothers skilled in the art to` which it 'apperta'ins to `make Yand use the same', reference bein-g had Ato; theV accompanying drawings, andV tothe figures which form a" part of this speciiication.
This invention relates to a screw holding attachment for screw drivers and vthev object which may be readily applied to existing types of screw drivers in'such a manner that the screw can be held in'position tofcause` the blade ot the screw driver to engage the groove in the head ot thescrew. I
The attachment can be instantly applied and detached trointhe screw driver shank.

The two members are eachy provided with one member extending through.v an opening vin. the ear of the `other member so that aV V,over portions orlips 5 .der the screw head 7.-
Each member isa duplicate o'-theother,
there being` no'rights and` let-ts. Therefore,
hinge joint is inadetoprovideatiilcrninfor 'pivoting the two vmembers together:
the parts need ynotV be matched 'becausefthe prong of? one wil-lenter the `openingrnthe ear of theotherlmember;asjwilli'be'clearly apparent 'by reference to Fig? 6.
