F 28 is a fragmentary sectional view taken on the line 24-24 of Fig. 20.

The advantages of the invention as here outlinedvare best realized when all ofits featuresand instrumentalities are combined in one and the same structure, but, useful devices maybe producedV embodying less than the whole. I v .n YIt will be obvious to those skilled in the art towhich the invention appertains, that the saine may be incorporated in several different constructions.A The accompanying drawing,

therefore', is lsubmitted merely as showing theY preferred exemplification ofthe invention.

Generally described, the invention provides a re-enforcing safety tool handle which is .made of wood and is anchored in an improved manner to the head of the tool. 'The means provided by my invention serves on 'the one hand to increase 'the' strengthof the handle, and, incidently, the weight thereof where this maybe desirable. F urt-hermore, the said means strongly connects the handle with the headof the tool, this latter purpose being aided by an improved anchorage which has abutment relation with the head of the tool which seats against an end of -the'handle. One element of the vanchorage may take the form of across7 and the head of the tool may be recessed to receive the ends or points of the cross. Coacting with this element betweenthe arms -thereof is a member which may-be either in the nature of a soft metal, as, for example, solder that is filled into the portions of the opening of the headsof the tool about the cross, or it may be cast integral-y ly with the head of the tool, thus providing an opening in the tool which conforms tothe shape of the cross and in which the latter seats as aforesaid. l/Vithin this basic principle, various modifications may be made, a number of which are illustrated in the drawings. The invention, however, is not to be construed as limited to theprecise features vof construction shown, but alterations, modifications, or changes withinthe scope of the invention may be made. Thus, for example, while the re-enforcing rod for the handle is shown in one particular instance havingV headed engagement with the anchorage, and in another instance having threaded engagement therewith, it will be understood that in each of themodifications shown, the connection may be either riveted, welded, 'or threaded. Further, if desired, the points of the cross may be welded in the said recesses.

Additional anchor means for the re-enforcing rod for the tool handle may take the form of a circle with arms at right angles thatma'y engage the plate having recesses therein either above or below the plate and rigidly se'curerthe rod thereto.

Referring in detail to the drawing, 20a denotes a device embodying the invention. The same includes a tool handle 21 having a lower main portion 22 that is adapted to be gripped by the hand of the operator and an upper portion 33 Vwhich constitutes an anchorage. The latter is adapted for engagement with any device as may be found necessary or desirable preferably inr connection with parts of tools of various types. In the drawing herein disclosed the said tool handle is shown as used in conjunction with a hammer head 24e, but it is understood that this is'shown merely as illustrative of the invention and is not'to be construed in a limiting sense. The tool handle 21 has an axial opening 25 extending longitudinally thereof, and in the said opening is a re-enforcing rod 26 extending substantially from end to end of the tool handle. While the tool handle may be made yof any suitable material that possesses the requisite strength and toughness, yet it will suflice to represent the same as being made of wood. VOn the other hand, the rod 26 is made of a metal that reenforces the tool handle and is also capable ofexertinga tension thereon in a longitudinal direction as hereinafter more particularly described. At the upper portion of the tool handle, the latter has engagement by means of the rod 26 with lthe anchorage 33, this kengagement being provided by threaded, welded, or riveted means.

In fact, the rod 26 may even vbe differently secured with the anchorage 33 and any particular means of connection set forth hereinafter is intended to be merely illustrative, and not to limit me as-to the scope of the invention. At its other end, the-rod 26 is threaded as shown at 27, the thread having engagement with a cylindrical nut 28 that sets into a recess 29 of thetool handle. A washer 30 may be interposed between the nut 28 and the closed end of the recess. One end of the nut may beformed with a kerf 31 for engagement by means of a' screw driver so as to permit any desired tension to be exerted on the rod 26 in order to increase the'snugness of the engagementof the anchorage 33 with the body 22 of thetool handle. y

The anchorage 38 ofthe tool handle meets with the inner end 32v of'the Vlatter and may beof different forms, only a few vof "which are Ashown in the drawingV One form of they anchorage may consi'stofa crossniember 33 having plurality of arms 34 along axes that` intersect at` right 2anglesland lie ina plane perpendicular Lto the tool handle. 'The cross member 33 has a central hole35 which is countersunk at136 to receive the head 37 and may be welded to the anchor member k33.A

There is also an opening 39 yin the upper end or face of the'head of the "hammer or tool to receive the anchoragef33 ``coac'ting with the 'underside vof the lanchor member v33.` I The wall'f41'is centrally lperforated topermit the passage'therethrough of thev reenforcing rod 26,.` It will now be `se'enj'tha-t on turning the nut 28,'the parts of the.tool'ha'ndleare drawn'ti'ghtly together'- f with a high ydegree ofi tension vso that the safety of ,they tool lhandle is rendered a AmaX- imum; More particularly, the head ofthe tool "handle is strongly fengaged against 'l looseningdue to repeated and strenuousluse.

In Figs. 7fand 8gi's showna -further modiication of `'a 'toolhandlerelating more .par-VA ticularly to the anchorage thereof" The princ ciple involved in this modilication'is similar j to thatof the foregoing devices-2y Inthis modi ilication the head of the tool handle lhas an oblong opening 56 Which receives in its upper portion ananchor plate 58 which is substantially rectangular form, but having semi-circular projections 59, or the like, that extend into similar recesses 60 inthe walls of of the said fopening.Vv `l/Vhilethe'plateoS is,`

approximately coeXtensive with the 'opening 56, the projections 59 extend therebeyond andi seat atGlVso as to'form a proper abutment to take up thetensionon a re-enforcing rod 62. L

Connected kwiththe,plate58 is, -a sleeve 63 having `threaded en'gagem,ent at 64 with the upper .end of the reenforcing rod 62 ofthe tool handle. kThe sleeve`63 isundercut to form aneclr portion that extends through'aholen 66 inthe anchor plate and the topof rod` 62"- islheaded over into a lcountersink of the plate p.

The rod is thus brought under tension to strongly secure together the several parts of the '"tool handle as heretofore mentioned. The plate 73 maybe ofja metal that possesses a high degree of toughness, while the cross member 7 5 is of a-metal that is comparatively veryhard so as to afford the proper anchorage for-'the re-enforcing rod. Furthermore, the said rod may be connected in various ways tothe cross member, although according to this construction, the rod, the plate 7 3, and the cross member 75'are separate and upon being assembled together are retained in snug engagement by the tension on the rod.v

In Figs. 11 and 12 is shown a modification of the nut for the re-enforcing rod, said modification providing a nut which has a through openingv 81 that is threadedfor engagement with the threaded portion of the reenforcing rod 26. At its lower end are pro- Y vided a plurality of kerfs S2 intersecting at right angles. 'In all other respects the'nut 80 is similar to the nut 28 and operates in a like manner.

In Figs. 13, 111, 15 is shown a modification of the reenforced safety tool handle as ap- 3,0

the openingmay be elliptical, rectangular or may be curved at both ends or with one end smaller than the other as shown in Fig. 14. i

Thus the tool head 83 has an elliptical open,- 35 ing 84; which seats a plate 85 through the intermediacy of lugs 86 thereon according to theprinciple hereinbefore described. Y The re-enforcing iod 87 is headed over as shown into thev countersink in the plate. In Figs. 111 and 15 the tool head 88 has an opening 89 receiving a plate 90 that seats therein in any suitable manner. The plate 90 may however also be provided with lugs as in Fig. 13 that sety into recesses in head 8,8. To afford a most reliable connection between the tool handle,

re-enforcing rod, and the plate 90, the latterl and has a pair of arms 92 seated in the recess 5.0 `of the plate 90. Member 91 is countersunk at 93 to receive the head ofthe rod aforementioned Awhich passesrthrough the hole 94a,V

In Figs. 17 and 18 is shown a further modification of a tool handle which will be under- 55 stood to be generally similar in the conformation of parts to that disclosed in Figs. i 9.and 10 except that the co-operating parts are welded together into one unitary construction. More specifically, the anchor plate 95 and cross 96 positioned therein and the re-enforoing rod`97 engaging the cross member may be subjected to heat and pressure and united along their meeting edges. Of

course if desired, the lugs 98 of the anchor .gplatemaybe weldedto ther tool Vhandle head y plied to aXe or a hatchet.v Thus the form of 99 'iny the recesses 100 of the latter. This lat-` ter may be employed also inthe modifications hereinbefore described.

In Fig. 19 is shown a further modification l Vat the said notch in the adjacent portions of the said plate forced into engagement with the notch. I-Ierer of course soldering may be resorted to. VThis device is adapted to be used in an axe or hatchet in the same manner as shown in Figs. 13 and 14. Of course the connection as between the rod 101 and the plate may be strengthened by heading over the upper end of 104C of the rod. l

In Figs. 20 and 23 is shown a still further modification of a tool handle, the same comprising an anchor plate 105 which is of substantially oblong form to set into a corresponding opening in a tool handle head 106, the said anchor plate having lugs 107 at the sides thereof functioning as hereinbefore more particularly set forth. Coacting with the refenforcing rod 108 is acircular plate.y

109 Vwhich is set into a recess in the plate 105, the circular plate 10.9being integral with or welded to the rod 108vto fit snugly in place, and a suitable washer 109a being interposed beneath the circularplate 109 and the bottom of the recess receiving the same.-

I-,n Figs. 21 and 22 are shown stillfurther modifications o f. tool handles having anchor plates 110 andl 111, respectively, the former being of star shape'land the latter being of circular shape. Thev re-enforcing tool handle rods 112 and 113 have connection with the plates vby either threading, welding, or riveting means.
