ANGULAR-SOCKET WRENCH.

reissue led December 20,

To aZZ whom t may concem Be it known that I, GEORGE R. FULLEN- WIDER, a citizen of the United States, and a iesident of Fairfield, in the county of Teton and State of Montana, have made certain new and useful Improvements in An lar- Socket lVrenches, of which the following is a specification.

My present invention relates to improvements in angular socket wrenches, and my object is the provision of an eil'ective and eiiicient tool of this nature, which will be compact and convenient in use, and which will provide for the utilization of a plurality of implements, with means whereby to normally house such im lements, provide for their independent uti ization, and normally prevent loss thereof.

With this general statement in mind, my present invention resides in the features of construction, arrangement and operation to be now described in detail in connection with the accompanying drawing forming a part of this specication, and wherein Figure 1 is a perspective view illustrating the practical application of my improved Wrench;

Fig. 2 iS therethrough 5 Fig. 3 is a similar view enlarged and partly broken awa Fig. `4 is a detailI perspective view of the end cap of the wrench;

Figs. 5 to 8 inclusive are detail perspective views illustrating dii'erent forms of implements utilized with the tool, and

Fig. 9 is a detail section taken substantially on line 9 9 of Fig. 3.

eferring now to these figures, and particularly to Figs. 1, 2, and 3, my improved wrench consists of a tubular barrel or casing 10, having at one end a portion 11 extending at an angle to the longitudinal axis of the tool, the latter being open at both ends and having its main or body portion of considerably greater length than its angular extension 11. Telescoping within the body portion of the barrel or casing 10 is a tubular shaft 12, provided at one end adjacent the angular end 11 of the barrell with extending apei'tured ears 13, diametrically opposed to one another, and having at its opposite end an enlarged head 14, which opposes and abuts the adjacent end of the body of the barrel 10 for a purpose which will be presa longitudinal section taken to provide for Specication of Beissued Letters Patent. Reigsued Apr. 26 192L Original No. 1,310,473, dated July 22, 1919, Serial No. 253,430, led September 10, 1918.

Application for 1919. Serial No. 346,378.

ently described, this head 14 having diametricaliy opposed openin s 15 and having an internal groove 16 the itter of which is mostplainl seen in ig. 3.

Hthin t e angular end 11 of the barrel .10, is telescoped a rotatable tubular engaging implement 17, having a polygonal socket 18 at its outer end and having pro'ecting ears 19 at its inner end diametrlca ly opposed to one another and provided with apertures so that the adjacent ends of said reduced portions projecting through the ears 13 of the shaft 12 and the implement 17 is thus permanently mounted withinthe angular end 11 of the barrel by a taper pin 22 which is forced through the other openings of the ball 20 and through the openings of the ears 19 of said implement 17, so as to complete the connection, the barrel or casing 10 having side openings 23, as seen in Fig. 1, the introduction of the taper pin 22, and also for its removal when desired.

The headed end of the tubular shaft 12, which of course projects beyond the adjacent end of the barrel or casing 10, receives therein the split sleeve 24 of a cap 25 normally closing the outer end of the tubular shaft, the several sections of split sleeve 24 having ribs adjacent their free ends which 'when the cap is in operative position en age within the groove 16 internally of hea 14, in order to hold the cap and prevent accidental displacement and loss thereof.

Certain of the sections of the split sleeve 24 also have side recesses forming openings 2T at diametrically opposite points of the sleeve to aline with the openings 15 of the head 14, although of slightl reduced diameter with respect to the atter openings. The handle of the wrench isin the nature of a cylindrical rod 28, as seen in Figs. 1 and 2, in the former figure in active position, and in the latter osition in inactive position, and this bandi; may be extended at either end through the openin s 15 of the head 14 and consequently throng the openings 27 of the split sleeve 24, the latter -of which beingil of reduced diameter serve to bring about a clasping of certain of the sections of the split sleeve upon the handle so as to frictionally grip the latter and hold 1t in various positions against displacement and loss while in use.

1n addition to its polygonal socket 18, the permanent socket implement 17 has an inner annular groove which supports a spring clamping ring 29 in order to hold various supplemental engaging implements in active position against danger of displacement and loss. Several ot' these implements are shown in Figs. 5 to 8, inclusive, and each has a polygonal body 30, with a reduced annularly grooved extension 31 at one end thereof, the body 30 in each case intertiting the polygonal socket 18 and the reduced extension 31 being engageable by the split ring 29. The form o the extension 31 is such that the ring 29 will be expanded upon the forcible insertion of the implement into the socket, and will snap into the annular groove and embrace the extension in such fashion as to secure and retain it in the socket during its intended use, whence it may be withdrawn by the application of force sufficient to expand the ring out of the groove.

The body 30 of the implement shown in Fig. 5, has a squared extension 32 to interiit a nut having a squared socket. The body 30 of the implement shown in Fi 6 has a screw driver 33, the body 30 of ig. 7 has valve engaging pins 34 for use in grinding or seating valves and the body 3() of Fig. 8 has a polygonal socket 35 of a different size than that of the socket 18 of the permanent implement 17.

Each of the implements shown in Figs. 5 to 8, inclusive, with the `exception of the implement of Fig. 6 is tubular, so as to receive the handle 28 therethrough when the several detachable implements are housed within the hollow shaft 12, as shown in dotted lines in Fig. 2, the handle 28 being also housed therein and extending through such implements. The handle, it will be noted, is of reducedlength as compared to that of hollow shaft 12, so that space thus remains for the reception of the screw driver member of Fig. 6.

Thus it is obvious that when it is de sired to use the tool, the cap 25 is first pulled out and the handle 28 removed from the space within the hollow shaft 12 along with the ,several im lements also housed therein, and from which the implement desired for use is selected. This implement is then thrust within the permanent socket member 17, cap 25 isreplaced, and handle 28 is extended to the desired point through the openings 15 of the head 14, as seen in Fig` 1. The detachably held implement is then placed in connection with either a nut, valve, screw or the like, as the case may be, and withthe barrel or casing firmly held to support the tool in proper position, as by means of the operator grasping its intermediate knurled exterior portion 36, as seen in Fig. 1, the handle 28 may be grasped and by rotating the head 14 a similar movement is transmitted through the tubular shaft 12 and through the universal connection 2 to the permanent socket member 17 and thus through the polygonal socket of the latter to the detachably held implement.

It is obvious therefore that my invention provides a comparatively simple and inexpensive tool, which may be economically and readily utilized for various purposes, for which implements of this character are intended,ras well as one which will be strong and durable in use and eii'ective and efficient in its results.

It is obvious also that in order to properly maintain the universal connection at the an le between the body of the barrel or casing 10 and its extension 11, it is necessary that the natural thrust of the hollovvr shaft 12 by the person operating the same in use must be taken up, this function being in the present construction performed by the enlar ed head 14 at the outer end of the said tubu ar shaft, which abuts the adjacent end of the said barrel or casing, and the shoulder of the member 17 which abuts the end of the an lar extension. The wall rtions of the arrel in the inside and outside of the angular bend coperate to give the structure maximum stiffness at the bend, and serve also to retain the connecting ears 13 and 19 against outward displacement.

While the implement 17 has been designated herein as a socket member, and is described as being adapted to embrace the polygonal bod portions 30 of the various engaging imp ements, it is obvious that the objects of the invention can in a measure be attained by forming the portion 18 of the engaging implement 17 as a stud member and the portions 3() of the engaging implements as sockets.

It will be apparent that the invention is otherwise susceptible of embodiment in various structural forms, without departure from the essence thereof, wherefore the drawings and description are to be taken in an illustrative and not in an unnecessarily limiting sense.
