soCKET WRENCHJ Application filed October 4,'1919. seriarno. 328,499.
TO all whom it may concem: n
Be it known that I, ROY H. SMTH, a citi- Zen of the United States, residing at Kent, in the county of Portage and State' of Ohio, have invented a certain new and useful Tmprovement in Socket l/Vrenches, of which the following is a full, clear, and eXact Clescription. l
This nvention relates 'to socket wrenches' adapted particularly for setting and removing rin] nuts of a demountable rim automatic wheel.
The object of the nvent-ion is to provide an efficient wrench which may be formed from a straight rod or bar of iron, steel or other metal, with the ends of the rod form-v ing handles for manipulating the wrench, and an intermediate portion of the rod doubled on itself to form the shank of the closed end of which the wrench head is formed. 4
The invention may be briefly summarized as consisting in certainnovel details of construction which will be described n .the specification and set forth in the appended claims.
In the accompanying sheet of drawings wherein I have shown two slightly different forms of a wrench, 'and also the preferable way in which it is formed, Fig. 1 is a per spective view of a wrench embodied in my nvention; Fig. 2 is a similar view showing a slight modification; Fig. 3 is a sectional view substantially along the line 3-3 of Fig. 1, looking in the direction indicated by the' arrows; Fig. 4 shows the manner in Which a rod is first hent to form the wrench; Fig. 5 is a view illustratng 'the manner in which the head is upset On the shank of the wrench formed by doubling the rod upon itself; and Fig. 6 is a similar view showing the manner in which the socket is formedn the upset head. r
As will subsequently appear, the wrench' formed by continuations of the handle portions which are joined together forming a shank which'is double the size of either handle portion. At the end of the shank opposite to'the end from which the handies project, s formed the wrench head 12, containing'a wrench socket 13. As will suhse quently appear, the two portionsof the -rod forming' the shank are preferably welded to'- gether when the doubled'or closed end of the shank is upset, and though the weld between the two parts of the shank is preferably extended from the wrench head to, Or Substantially to the point where' the 'parts of the shank diverge to form the handles, never-, theless it is not essential that the two portions formng the shank be thus welded together to the eXtent stated.
In making the wrench I prefer to form at the free end of one of the handles'a taper 141, to form a screw-driver, and 'if desired, one of the handles may have a portion indicated at 10 bent at right angles to the main' portion of the handle toform a Crank by which the wrench can be quickly turned or spun to quckly remove or set the nut.
This wrench may be formed in different ways but preferably, I start with a'rod which is of suitable size, formed of suitable stock 'cut to the right length, and this rod is preferably hent in the cold' to form the handle portions 10, and a double shank which s" designated 11 in Fig. 4, the two portions' forming the shank 11 extending in Substantial parallelism from the handle portions to the closed end. Then' the double portion of the rod is heated to a Welding heat and is clamped between a pair of dies 15, 'prefer-. ably with sufficient pressure to weld together the two parallel parts forming the.
doubled portion. When t, s thus gripped in the dies 15, the closed end projects from the dies, and by a 'suitable upsetting tool, indicated at 16, a head 17, shown bydotted lines in Fig. ,5 is upset thereon. Then the ipartially formed tool is transferred to dies 18, or to a different portion of the dies 15 which are recessed substantially as' shown in Fig. '6, and by a suitable tool 19, a wrench' socket of the proper shape is formed 'in the upset end 17. Preferably a porton 20 of the socket forming tool s extended into the recess receivng the upset end of' the shank so as to give a finish to the socketedend of the wrench.
' This produces a finished wrench ,made from one piece of metal in a form such that it is strong and serviceable but can be very readily manipulated.
'The process above described and illusi'aed in he drawing s not Ciaime herein. hut COlSt-UGS the subject matter of a Companion application filed by me of even date herewith. v
Having described my invention claim, A One-piece WrenCh comprising a shank provided at One end With an integrai wrench beach and at the Other end With pair of laterally extending handles, the metal formthe handles having a substantaiiy right angle heild :it the end of the shank and for a. distance extending along the shaiik in'suhstaniiai gmralleiism, and then being uniteci meme i to form One substantally solin part which extens to the head.
2. A One-piece socket wi'ench comprising a suhstantiaily cii'cuiai' sOCketed Wl'QllCil head, a shank integral with the head and of elcngated Cross-section; said shank at a dis- *Dance from the head being divided into 20 hande portions, each O' substantally Onehalf the cross-sectional area of the elongate. portion O' ,the Shit-nk.
