INTERCHANGEAIBLE WRENCH DIR/OTHER TOOL HOLDER.

. Application filed September 18, i923. Serial No. 663,357.

This invention relates to wrenches or tool holders in 1 general, but more particularly to thosewhich are adaptedto be extended,,by the'use of auxiliary socket pieces, in order to fit bolts or nuts of different sizes or for other purposesi r a Generally stated, theob1ectof the invention is to provide a novel andjlmproved form 'offspring'coupling by which to connect a I socket piece or other tool to the tool holder,"

softhat the wrench socketor other device may beeasily' detached, but whereby it Will besecurely held in place for use.

It isalso an object to provide certaindetails and features of construction and combinations tending to increase the general elliciency and desirability of a wrench or other tool holder of this, particularcharacter.

' To these and other useful endsthe invention consists in matters hereinafter set forth ing drawings in wh1ch I v v Figure 1 is a side elevation of a wrench or tool holder embodying the principles of and claimed and shown in the'accompany- Figure 2 is a vertical section of the tool holder, showing a portion of the transverse handle rod in place for rotation of. the wrench oroth ertool.

Figure 3 is a transverse section on line 3-3 in Figure 2. V e V F igure4 is a side'elevation of a Wrench 7 socketfor insertion in the lower end of the tool holder shown in Figures 1 and 2.

Figure 5 is aside elevation, partly 1n section, with certain portions broken away for convenience of illustration, of an extension socket for insertion in the lower end of the tool holder shown in Figures 1' and 2, there- 4o to in effect lengthen thetool holder for e convenient operation. I I Figure 6 is a plan of the sheet metal blank from which the spring shown in Figures 2 and 5 is made.

v Figure 7 is a bottom view o f-said blank after the pro ections thereof have been bent into the desired shape; V V g 1 Figure 8 is a side elevationof the completedspring shown in Figure 7. v

opposite direction.

As thus illustrated, the invention com prises a tool holder having a socket piece 1 the interior of which is polygonal at 2 to,fit' the nut or bolt head, or to fit the extension shown in Figure at orthe extension shown in Figure ,5, so that the tool holder may in effect be lengthened when necessary, The socket piece 1 has its interior provided with the spring shown in Figures 7 and 8, comprising bent end portions 3 for engagement with-the circumferential groove 1 on them) socket piece or extensionshown in Figure 4, or the similar groove d'shown in Figure 5 of the drawings. The spring is secured in place by a screw 5 which is inserted up- I \vardly in the socket piece -1,'so that the'05 spring can be removed when necessary. The portions ,3 are normally, of course, out of en gagement with the sides, of the socket piece, for clearance as shown is formed around the sprmgmeans above the polygonal:port1on 2,vthus permitt ng the portions '3 to be pushed outward toward the sides of the socket. A double ratchet member 6 is interposed between the socket piece 1 and the body member 7 of the toolholder, and 7 the shifting sleeve 8 is mounted to slide up and down thereon, it being observed that the ratchet member 6 and the portions immediately above and below are polygonal, said sleeve being made correspondingly polygonal inside to fit thereon. Consequently when the sleeve is down as shown in Figure 2 the member 6 and the socket piece 1 arelocked together and the top ratchet will, be operavtive by oscillation of'the handle 9' to intermittently rotate the socket piece 1 in one direction; but whenthe sleeve 8 is raised,

as shown in Figure 1, then the member .6 and the body portion 7 are locked together, and the lower ratchet willbeoperative to intermittently rotate the socket piece 1 in the The socket piece 1 has a stem 10 which carries a coil, spring 11, and the washer 12 is held at the upper end of this stem by a pin 13, so that said spring is compressed between this washer and the shoulder 14 formed on the interior of the body portion 'Tofthe tool holder. However, said spring is adapted to yield when the ratchet teeth slide backward over each other,

in a manner that will be readily understood. An opening lel is pr i1vided at each side ol the tool holder :tor the insertion and removal of the pin 13, and a spring pressed. member 15 is provided to l rictionally hold the hendle rod 9 in position for (nieration, which rod can be withdrawn when "it is desired to pack the tool holder in a box. It will also be seen that the upper portion of the tool holder provided with a polygonal end portion 16, and above this with a groove 1? like the groove '5 previously mentioiiedr Thus a detachable socket piece like the one shown at the bottom of Figure 5, or like the one shown in Figure 4-, can he slipped over the upper end of the toolholder, above the rod 9, to connect any necessary or desired. device to the upper end of the tool holder. The polygonal portions 1'8 shown in Fig ores l and a are adapted to iii the polygonal portion .2 oi? the tool holder socket, and the springs 3 hold the socket piece or onion-- sion in position for rotation by the ratchet; but a forcible pull on the extension or socket will easily detach it from the springs, when such is necessary or desirable. The socket )ieccs can have polygonal sockets of dillerentsizes, to fit bolts or outs of ditli'erent sizes, very obviously, and the extension can be of dill'erent engths so that the tool holder as n whohii can in ellect he lengthened in the desired manner. While WI'tIlUll sockets are shown, it is obvious that the polygonal portions 2 and 18 and the springs 3 and the grooves *ll: can be used as the coupling means for coupling any snitable tool or extension to the tool holder. The beveled edge portions 19 are formed to strike the lower ends of the springs 3 and crowd them outward, so that their lower end portions will then snap into the groove l; and it will also be seen that a similar beveled edge portion 20 is provided for a similar purpose at the top of the tool holder.

\Vhat I claim as my invention is-- 1. In a wrench or tool holder, the combination of a socket piece having inner cylindrical sides, means for rotating said socket piece, a sheet inetal spring having integral and inwardly lacing engaging portions radially disposed in said socket piec spaced equidistant at more than two points on a circle struck from the axis oi. said HOClTOlZ piece, normally out of engagcn'ient with and a distance from the inner Sit of the socket piece, with cl airance in the socket between the inner cylindrical sides thereof and the outer sides of said engaging pmtions, to permit, outward radial movement of said engaging portions, a tool or extension for insertion in said socket piece, means comprising a single axial screw to hold said spring portions in operative position, said tool or extension having an external groove to be engagml by said spring engaging portions,

and said tool or extension and socket piece being relatiwel formed to prevent relative rotation between them, providing a rcin ricted polygonal opening below said cyliinlricai sides, whereby rotation oi. the

socket piece will rotate the tool or exten-i spaced equidistant at more than two oints i on a circle struck from the axiso said socket piece, normally out of engagement with and a. distance from thelnner sides of the socket piece, with clearance in thesocket between the inner cylindrical sides thereof and the enter sides of said engaging portions, to permit outward radial movement of said enoaging portions, a tool or extension l'or inset tion in said socket piece, means coinprising a single axial screw to hold said spring portions in o Jcrative position,said tool or extension having an external groove to he engaged by said spring engaging portions, and said tool or extension and socket piece being relatively formed to prevent in relative rotation between them, providing a restricted polygonal opening below said cylindrical sides, whereby rotation of "the socket piece will rotate the tool or extensien, said spring m ans being removable readily from said socket, said tool having its enter end formed with a socket containi inga spring siini.larto the one in said socket piece, so that another tool can be inserted U] the extension thus provided.
