w. H WALKER COMBINED JACK HANDLE AND TIRE LUG WRENCH Filed July 6, 1926 all) Patent ululy 30, 192%..
WARREN H. WALKER, OF BACINE, WISCONSIN, ASSIGNOR T0 WALKER MANUFAC- TUBING COMPANY, OF RACINE, WISCONSIN, A CORPORATION OF WISCONSIN.
COMBINED {TACK HANDLE AND TIRE-LUG WRENCH.
Applicationfiled July 6, 1926. Serial No. 120,772.
This invention relates to a combination tool, adapted to serve either as the operating handle for a lifting ack, or as a socket wrench for turning the nuts on the tire lugs.
In a. preferred form of the invent1on, the device is made in two detachable sections which, when assembled, serve as the operating handle for the lifting ack, and when detached one of the sections serves as the tire lug wrench.
The general object of the nvention isto provide a single tool, as brlefly described hereinabove, and as described in more detall hereinafter, which is capable of performing the functions of both a lifting jack handle and a tire lug wrench. I
Other objects and advantages of this 1nvention will be more apparent from the following detailed descriptions of certaln approved forms of the inventlon.
In the accompanying drawings:
Fig. 1 is an elevation of the complete device in use as a jack-handle.
Fig. 2 is a similar View of the assembled device, detached from the jack, the connection between the two sections of the device being shown in central longitudinal section.
Fig. 3 is an elevation of the detached crank portion of the device.
Fig. 4% is an elevation of this portion of the device in use as a tire lug wrench, a portion of a tire, rim, and wheel being shown in transverse section.
Fig. 5 is an elevation of the extension member, shown folded or collapsed for convenience in storage.
Fig. 6 is a transverse section, on an enlarged scale, taken substantially on the line 66 of Fig. 2.
Fig. 7 is an end view of one end of the extension rod.
Fig. 8 is a side elevation of one end of this rod, the extreme end portion being shown in central longitudinal section to illustrate the spring-detent. mechanism.
Fig. 9 is a transverse section, on an enlarged scale, taken substantially on the line 9-9 of Fig. 2.
Fig. 10 is a side elevation of a simplified form of extension rod.
Referring first to the drawings the jackhandle is formed of two detachable portions, one of which is in the form of a crank wrench quite similar to the ordinary tire lug wrenches now in use. As shown in Figs. 3
and 4, this portion of the device may be formed of a continuous metal bar or rod, of preferably round cross-section, bent to form an operating crank or handle 1, connected by the right-angled portion 2 with the operating shaft 3. If desired, a rotatable sleeve or handle-grip 41 may be mounted on the shaft 3, but this feature is optional and may be omitted. At the end of shaft 3 is secured a wrench head 5 in which is formed a socket 6 adapted to fit one of thenuts (usually hexagonal), which hold in place the lugs 7 for securing the rim 8 of tire 9 on a wheel, as partially illustrated at 10.
The head-5 is also formed with anothersmaller socket extension 11, usually square in crosssection and substantially the same inform and dimensions as the socket in the end of the actuating stub-shaft 12 of the lifting jack. A typical lifting jack is shown in Fig. 1, comprising a standard 13 and lifting screws 14, which are elevated or lowered by i the driving gear or nut 15 driven by the beveled gear 16 on the inner end of stubshaft 12. This jack is merely shown by way of example, and this improved handle could be used with any lifting jack which is actuated by a rotatable or oscillatable shaft. Preferably, one or more recesses 17 are formed in the sides of the sockets 11 in both the head 5 and the shaft 12 of the lifting jack. These recesses 17 are to beengaged by spring detents in the extension rod hereinafter described.
When used as a lifting jack handle, an extension rod is provided adapted to form a continuation of the shaft 3, so that when the jack is located in operating position beneath the axle of a car, the crank will ext-end out to an accessible position beyond the body of the machine. This extension member may be simply a continuous straight rod or bar 18, as shown in Fig. 10, conveniently made of round bar material, although the end portions 19 must be square or of other suitable non-circular cross-section to. fit the sockets 11 in the head 5 and shaft 12 of the lifting jack. Each head 19 is preferably beveled off at the end edges, as shown at 20, to facilitate the insertion of the rod end in the socket. A ball detent 21 is mounted loosely in a recess 22 formed in the end 19, and is urged outwardly by a spring 23 to a. partially projecting position in which it is held by the inturned walls 24 surrounding the entrance to recess 22. One ball detent 21- may be used, or a pair of these detents may be urged in opposite directions by the same spring 23 confined therebetween, as shown in Fig. 8. When the end 19 of the extension rod is forced into'the socket 11, the balls 21 will give against the resistance of spring 23 and will subsequently snap .into the recesses 17 to hold the head 19 yieldably within the socket 11 It is not absolutely necessary that the socket 11 within the wrench head 5 be identical in form or size with the socket in the operating shaft 12 of the lifting jack, because the two ends 19 of the extension bar 18 could be suitably formed to fit the respective sockets. However, it is preferable v to have these two sockets identical, and the ends 19 of the extension rod identical so that no care need be exercised in fitting the proper head in the proper socket.
Instead of using a single continuous extension rod 18, as shown in.Fig.10, it is preferable, as illustrated in Figs. 2, 5 and 6 to divide this rod into two similar portions 25 and 26, the ad'acentends of which are pivoted at 27 wit in' a clamp member 28. This clamp member 28 has its end portions crimped inwardly at 29 and 30 so as to hold the sections 25 and 26 in alinement when extended to the position shown in Figs. 2 and 6. However, the crimped portions 30 will yield so that the members 25 and 26 may be folded and collapsed they are of convenient size for storage in the tool box of the car. When only the tire lug wrench is required, the extension rod portion need not be used at all. When the lifting jack is to be operated, the handle is easily assembled by simply folding out the rod sections 25 and 26 into alinement and inserting either end of this device into the socket -11 in the wrench head 5. The handle is then attached to the 'ack in' the usual manner. There is a eonsi erable saving in initial cost since one crank ortion serves both as the tire lu wrench an as the crank portion of the jac handle, and there is also a' material economy in storage space and dead weight to be carried in the car.
