SCREW DRIVER AND SOCKET WRENCH ATTACHMENT Filed Sept. 25, 1936 I8 1 l9 17 I0 I I THOMAS MILL E R INVENTOR.
BY W Main ATTORNEY Patented F b. '15, 193s -NlTE SUREW DRIVER 1. ii SQCKIE'E' WRENCH ATTACHNT Thomas mlle'r, Brooklyn," N. W ApplicationSept'ember 25, last, Serial No. 102,467 I his.v (cast-rel) I This invention relates to socket wrenches operated by a screw driver and an object is to provide a simple duplex clip mounted on the socket wrench and-adapted to grip the reduced shank a portion above the bit of the screw driver.
Another object of this invention is to provide a socket wrench having integrally secured there-r to a duplex elastic resilient spring clip having two arms disposed longitudinally of the socket lid and designed for resiliently gripping theshank portion above the bit of a screw driver having sideways extending shoulders whereby the arms interlock with said shank portion directly above said shoulders and afford, suiiicient resistance it against disengagement while'at' the same time a comparatively slight push or pull applied centrally to the screw driver through the medium of its handle is suficient to overcome the resistance afiorded by the spring arms so that the screw 2o driver may be intentionally removed or replaced with comparative ease. f
Another object of this invention is to provide modified engagement means whereby the duplex clip is mounted in the socket wrench and is adaptas edto grip the end walls of the bit of a screw "driver.
With the above and other objects in view, the invention will be hereinafter more particularly described, and the combination and arrangement dd of parts will be shown in the accompanying drawing and pointed out in the claims which form part of this specification.
Reference will now be had to the drawing;
wherein like numerals of reference designate cor-"' gs responding parts throughout the several views,

socket wrench body and holding means for screw- Figure 7 is a front elevation of an adapter used for coupling a screw driver and a socket wrench as body of usual construction.
In the illustrated embodiment of the invention shown in Figures 1 to 3 inclusive, the numeral id indicates the body of a socket wrench which preferably has an upper end ii of circular form Y and of smaller diameter than the lower end.. The 5 upper end has a rectangular and downwardly tapering opening it designedto permit entrance of the tapering bit of a screw driver.
Figure 1 shows the bit it of'a screw driver it I inserted in the opening it. The bit M is defined 10 from the'shank it by two shoulders it which project out from the shank. The widthof the bit at the shoulders is greater than that at its lower end it and when looking'at the front face appearslightly tapering with the smallest end of thetaper directed outward. v As shown in Figure 2; the lengthwise sides of the rectangular opening it taper considerably to correspond with the considerably tapering front and rear faces of the bit as is usual in screw driver construction. 1 v
For the purpose of securing the screw driver it and the socket wrench body it in unitary relation, I have provided a resilient holdingmeans it having a tubular body portion it designed to frictionally embrace the upper end ii of the body it, The tubular body portion i9 is slit at M in a longitudinal direction and the two edges at the slit are slightly curved outwardly. Projecting upwardly from the tubular body it are two arms 26 which are resilient in actiona d have inwardly turned ends or' terminals 22. e arms 2i slidably operate on opposite end walls of the bit it and interlock with the shank it above the shoulders iii. The arms Zi have at the free and inwardly turned ends 22 outwardly projecting extensions 23 which facilitate the insertion or removal of a screw driver from the opening i2.
It is to be noted that the tubular body portion M it of the resilient holding means it is designed so as to be frictionally slid over the reduced upper end ii of the socketwrench body It! 'andso that it may be removed'therefrom at will.
Figure 4 shows amodifled socket. wrench body 25 and a-mddifled resilient holding means 26. The modified socket wrench body 25 has a reduced upper end Ti and a circular. groove--28, best shown in Figure 5.-v The spring holding means 26 is preferablymade from a fiat annular 5 'body 29 which is split'at 3Iland haslongitudi pally extending spring arms 3i, similar to the 3 spring arms H. The extensions-32 of the arms 3| may be further extended and made in-cor-.
rug'ated form, as shown-at 33 in Figure 9: so that of the screw driver, the end wallsof the bit id 15 shown) and clamping the flat annular body 28 therein.
Figure 6 shows a modified socket wrench body 35 whichmay have a reduced upper end 36 and a duplex clip or resilient frictional holding means. =38 mounted in the body. The body 35 has an opening 31 designed forreceiving and securing a screw driver having parallel end walls.
Figure 7 shows an adapter 40 for-coupling a screw driver, having shoulders and a socket wrench body of usual construction, thatis, a
body 4| having an upper hexagonal opening-42 for a handle (not shown) and a lower hexagonal opening 43 tor receiving a hexagonal nut. The adapter 40 has a lower extension or handle 44 with the usual spring-pressed ball 45 for irice tional engagement with the opening 42 in the body 4|. The adapter body 40 has an opening 46 in its upper end to receive a screw driver (not Mounted on the body 40 is a circular spring clip 41 having an upper extension 48 and an inwardly turned end 49 which is designed for engagement with the shoulders of the shank of a screw driver similar to that shown in Figure 1.
It is to be noted that the spring holding means or clips shown herewith may have one ormore arms for securing a screw driver and these clips may'be permanently secured to the socket wrench body or may frictionally be, disengaged therefrom.
