To all whom t may concern:

Be it known that I, JULIAN H. FAW, a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Wrenches, of. which the following is a full, clear, and exact specification.

This invention relates to wrenches and particularly to socket wrenches having angular inclosing sockets for the nuts or other parts to be turned.

It is` the object of vide a Wrench of this in construction, comprising only two parts, and capableof easy operation for quickly applying or removing nuts or similar parts. The invention provides for applying considerable leverage when tightening or loosening a nut or bolt, and for veryquickly turning the same before tightening or after loosening when no great leverage or power is required.

These objects are attained by the use of a simple form of socket member and a straight handle bar of angular cross section. The socket member has a wrench socket in one end, and a transverse passage and an aXial passage in its other end portion, the

the invention to protype which is simple axial passage being of a shape to be en-` gaged by the handle bar when one end por' tion of the latter is inserted therein Jfor spinning the socket member quickly to or from the tightening position of the nut by rolling said handle bar betnfeen the palms of the hands. The transverse passage in the socket member is designed to be engaged by the end portion of the vhandle bar when greater leverage is desired for tightening or 4o loosening the nut.

ln the accompanying drawings,l wherein similar reference characters are used to designate corresponding parts in the several views "Figure l is an elevation of the wrench arranged for tightening or loosening a nut.

Figure 2 is an elevation ot' the wrench arranged for spinning a nut quickly to or from tightening position.

Figure 3 is a section on the line III-HI of Figure 2, showing the wrench applied to a nut. l

Figure 4 is a section on the line IV--IV of Figure 5. 'Figure 5 is a plan View oi the wrench as v shown in Figure 1, part of the handle bar being broken away, and

Fifure 6 is a lowerend view of the socket mem er of the wrench?.

The socket member 1 is preferably made of a single piece of suitable metal and may be generally cylindrical in shape, as shown. The handle bar 2 may be of suitable length and of any angular cross section, such as the hexagon shapeA illustrated. The transverse passage 3 in the up er end portion of the socket member is pre erably circular in crosssection, or otherwise shaped to receive the end portion of the handle bar in any position of its olyface'sides, so that the insertion of said) bar into said passage is facilitated and the consumption of time which might be required to introduce` the handle bar into a corres ondingly shaped transverse passage is avoi ed. l The axial passage in the upper end of the socket member is illustrated at 4, the same being ot corresponding shape to the cross section of the handle bar or of other suitable form to insure the turning of the socket member with the handle bar when the latter is in the position shown in Figs. 2 and 3. The angular socket 6. in the lower end of the socket member l may be shaped to fit any type of nut or bolt, and a round bore 5 may extend through the socket member between said socket 6 and the passage 4 if desired.

In operation, when a nut 7, Fig. 3, is to be applied to a bolt 8 for tigthening against an abutment 9, the handle bar 2 is inserted into the axial passa-ge 4 of the socket member and said nut quickly spun down to tightening position by rollingI said handle bar between the palms ofthe hands. The handle bar is then removed from the axial pas sage 4 and slipped into the transverse passage 3 in the socket member, as shown in Figs. 1 and 5, whereupon a short turn with the leverage provided by the radially extending handle bar will tighten said bolt against. the abutment 9. For loosening a tightened nut the handle bar is arranged in the transverse. passage 3, and after loosening, said handle bar is insertedin the axial passage 4 and rolled between the palms of the hands for quickly spinning the nut oilP of the bolt. lt will thus be seen that with the simple form of one-piece socket member and straight polyface handle bar shown nuts may be applied and tightened, or loosened and removed from their bolts more expeditiously than with prior yforms of wrenches of more complicated and expensive construction.

I claim 1. A wrench comprising-a socket member having a continuous axial 'passage extending therethrough,`the lower end portion of said passage constituting the nut-engaging recess, the upper end portion of .said passage being concentric with said nut-engaging recess and also of angular cross-sectional contour, and a handle bar of similar angular cross-sectional contour to lit said recess in the upper end ofsaid socket member, whereby said socket member may be spun ,for quickly turning vthe nut to or from tightening-position by rolling said handlebar between the palms ofthe hands, said socket member also having a transverse passage extending across the axial passage therem tol receive said handle bar for tightening or loosening a nut.

2. A wrench comprising a socket member having a continuous axial passage extending therethrough, the lower end portion of said passage constituting the nut-engaging recess, the upper end portion of said passage being concentric with said nut-engaging recess and also of angular cross-sectional con-A tour, and a handle bar of similar angular cross-sectional contour to fit said recess in the upper end of said socket member, whereby said socket member may bespun for quickly turning the nut to or from tightening position by rolling saidl handle bar between the palms of the hands, said socket member also having a transverse passage extending across the axial passage therein and opening on both sides of said member to receive said handle bar for tightening or loosening a nut.

3. A wrench comprising a socket member said passage constituting'the nut-engaging.

recess, the upper end portion of said pasvsage being concentric with said nut-engaging recess and also of angular cross-sectional contour, and a handle bar of similar angular cross-sectional contour to lit 'said vrecess in thev upper end of said socket member, whereby said socket member may be spun for quickly turning the nut to or from tightening position by rolling said bar between the palms of the hands, said'socket member also having a'transverse passage extending across the axial passage therein and opening 4on both sides .of said member to receive said handle bar for tightening or loosening a nut, said transverse passage being of a size to receive said-handle bar in any rotated position thereof.

4. A Wrench comprising a socket member having a continuous axial passage extendin therethrough, the lower end port-ion of sai passage constituting the nut-engaging recess, the upper end portion of said passage being concentric with said nut-engaging recess, and alsolof angularcross-sectional contour, and a handle bar of similar angular cross-sectional contour to lit said recess in the upperend of said socket member, whereby said socket member may be spun for quickly turning a nut to or from tightening position by rolling said bar between the v palms of the hands, and socketmemberalso having a transverse passage extending across the axial passage therein and opening on both sides of said member to receive said handle bar for tightening or loosening a nut` said transverse passage being round in crosssection -for the purpose specified.

In testimony whereof I have signed my name to this specification,

JULIAN H. FAW.
