The handle 6 is recessed at 22 to accommodate the cap 20 and is also cut down at 24 in order that the outer surface of the annular flange 26 of the cap 20 will be continuous with the surface of the handle 6.

A rod 28, preferably of metal, passes through the bore It at the tool head end of the handle. This rod is attached to a cap or plate 30, and in Fig. l is shown threaded in the plate. The plate 30 rests upon the shoulder or abutment 32 in the tool head 2. A clearance is preferably provided between the handle 6 and the cap or plate 38. At the bottom of the handle, the other end of the rod 28 projects beyond the central bore and through the cap 29. A washer 34 is provided between the cap 28 and the nut 36. By tightening the nut 36 the handle 6 will be drawn tightly and securely held against the tool head in the opening 4, which is usually tapered, and the tool head will be prevented from flying 01f the handle because of any loosening of the parts. If desired, the plate Bil may be so threaded that the rod will tighten itself therein when the nut 36 is being tightened at the other end of the rod 28.

In applying my invention to a tool having a curved handle, such as shown in Fig. 7, certain modifications have been found desirable. It will be noted that when a tie-rod of circular or elliptical cross-section is employed with a curved handle and the handle is tightened against the tool head by tightening the nut at the open end. of the handle, there is a tendency for the tierod to effect separation of the parts of the handle, due to pressure at the curves of the grooves. In order to counteract this tendency, I flatten the tie-rod at the curved portion 38 and shape the grooves to properly accommodate the flattened rod as will be evident by reference to Fig. 9. It will be seen from Figs. 8 and 10 that .the rod 28 is circular near the ends of the handle while in the central portion it is flat as shown in Fig. 9.

The flattening of the intermediate portion enables the rod to bend more easily around the curves and also aifords a good bearing area at the curves, thereby avoiding crushing of the fibers of the wood, whichwould cause a loosening of the tie-rod. In order to assure proper tightening under all conditions and to allow for the drawing'together of the handle and the tool head, the bore is preferably increased in size at 40 and 42 so as to accommodate the parts of the tie-rod of either circular or flattened structure.

In the construction shown in Figs. 1 to 10 the members of the handle are joined at the plane passing through the locus of the major axes of the cross-sections. This construction is preferred because in most cases the extra strength to the handle afforded by this arrangement is desirable. However, in some instances, my invention may also be employed to advantage by having the parts of the handle constructed not of halves but of complementary parts difiering in shape from each other. Such a construction is illustrated in Fig. 11 where the cross-section of the part 44 is a smaller sector of the ellipse than that of part 46. Also, my invention may be employed to advantage with handles wherein the tie-rod is positioned at a distance from the axis.

My invention is also applicable to the fastening and securing of rungs of a chair to the legs as shown in Fig. 13. In this case, therungs are formed of two parts 48 and 50 which are grooved to accommodate the tie-rod 52. The legs 54 are recessed at 55 to receive the washers 58 and nuts 60. The legs 54 are also recessed at 62 to receive the ends of the rungs comprising the sections 48 and 50. These rungs are positioned so that the plane between the parts 48 and 50 is vertical, because such arrangement adds to the strength and appearance. In this construction the rung serves as a strut and the tie-rod 52 as a tension member. After the rung and tie-rod have been positioned and tightened against the legs, the cavities or recesses containing the washers 58 and nuts 60 may be filled with putty or other filler so that the legs of the chair will present a smooth and neat finish.

The parts l8 and 59 of the rung may be glued together if desired, although generally the tight fit of the ends of the rungs in the recess 62 of the legs 54 is sufficient to keep the parts from 2 separating. By this construction a reliable means is provided for maintaining the legs of a chair or other article of furniture against separating and loosening from the rungs.

My invention is not only applicable to numerous other tools and articles of furniture than specifically illustrated herein, but may also be appropriated to advantage for many other uses; for example, golf clubs and other articles having parts that have a tendency to loosen and become disengaged from each other.

In the claims, the term nut is employed to cover various forms of mechanical nuts including those having the hole extending partially through, those having the hole extending en- 5 tirely through, those having the hole partially threaded and those having the hole entirely threaded.

The present invention is not limited to the specific details set forth in the foregoing examples which should be construed as illustrative and not by way of limitation, and in view of the numerous modifications which may be effected therein without departing from the spirit and scope of this invention, it is desired that 5 only such limitations be imposed as are indicated in the appended claims.
