1943. Application tor 2 Claims. (c. 16-125) This invention relates generally to handles and more especially to handies for tea kettles, coffee pots, pails and other oontainers having a wire or like ball and upon which is mounted a han gripping portion termed a handle. I

The present invention is an improvement upon that illustrated, described and claimed in Patent No. 2,319,147, dated May 11, 1943. In this patented structure the handle is sectionalized in that it consists of two identical half handles, each having a bail groove, a looking tongue to one side thereof, and a looking groove to` the opposite side thereof and spaced a like distance from the bail' groove, all grooves and tongues extending longitudinally of the handle, the half handles being assembled upon a bail, or together by end to end telescopic association of the looking tongues and grooves only and from either end.

The present invention is similar, except the half handles cannot be assembled from either end, but only from one end for obvious reasons.

The ormer handle was capable of ormation from various materials and readily lent itself to formation in long lengths (subsequently cut to handle length) by extrusion or by routing, etc., if formed from Wood or fibrerod stock.

Due to the reentrant character of the neck' of the looking tongue and the restricted throat of the looking groove, molding Was very slow and expensive and required multiple, collapsible dies, difiicultto obtain and expensive to maintain.

The handle of the present invention has as its chief objective, first, the automatic looking together of half handles when longitudinally brought together and, second, the rapid molding and ejection of the half handle from a simple die structure. This patentable improvement over the patented handle, accordingly, under present priorities permits the use of phenol-condensation material (not subject thereto) and which cannot `!oe used in an extrusion device.

The chief feature of the present invention consists in making each of the looking tongues and grooves of said patented identical half handles of longitudinally tapering type which, when longitudinally assembled, wedge lock together, and which, when formed as by molding, may be readily ejected from a partable mold, one part thereof being slidable relative to the other, all as hereinafter pointed out. i

Other objects and features of the invention will be set orth more fully hereinaiter. Also, mention of phenol-condensation material is by way of example only and not one oi restriction.

The tull nature of the invention will be under- 'ing iron or side wall of stood from the accompanying drawing and the following description and claims.

In the drawing,

Fig; l is a side elevation of a handle 'embodying the invention applied to an ofiset portion of a bail (see dotted lines) or a cofiee pot or Smoothing iron handle (see full lines) Fig. 2 is a central sectional View through the handle and handle support.

Fig. 3 is a plan view of one of handles.

For reasons assigned hereinbefore, the patented handle, while quite advantageous and desirable, has certain inherent objections or shortcomings principally in its fabrication in a mold and its non-looking when applied, whereas the present invention, while retaining most of the advantages of such patented handle and elirninating the inherent objections and shortcomings thereof, does not appear capable of fabrication in long units for subsequent reduction to shorter lengths, as by extrusion or routing, etc.

In Fig. 1, `0 indicates the top shell of a Smootha coee pot and extendthe similar half ing therefrom are arms supporting portion I2.

bucket or the like, portions l l may be oppositely directed as at I l 1 (see dotted lines). This forms a handle locating offset portion in the resulting bail.

Herein the handle proper includes two similar and complementary halves with a central plane of contact l4. The exterior may be slightly reduced at opposite ends as at !5. It is for this reason, among others that the present invention does not readily lend itself to continuous extrusion or reduction abrication. However, it does lend itself to expeditious repetitious molding production.

Each half handle !3 has a semi-circular crosssectioned (if desired) median groove e extending longitudinally thereof and same nests the baii central portion l2. Midway between the groove IS and each side edge l'l' is a Iongitudnally directed locking formation, the general direction of which is parallel to the groove IG and hence parallel to each other. It is not necessary that such fon-nation be equidistant from the side edge and groove !6, but it is essential that the formations be spaced equidistant either from the side edges l'l or the groove IS.

Herein such ormations are formed upon the face M and are of complementary character, that is, one is a groove I& and the other is a tongue IS.

The exact cross-sectional area and/or Outline ll connected by handle V When used for a pailf !4, however, the tapers are reversed andareidentioal as illustrated in Fig. 3. t Hence, when one complementary half handle 13 is held below portion I2 with same seated in ba] groove IS, the other half handle must have its smaller end of the tongue l9 presented to the' wider end of the looking groove !8 in theformer half handle and vice versa for the other cooperating pair of tongue and. groove formation. Then the said other handle is sld longitudinally of the said former half handle, movement thereof being limited by portions ll, until thetapered walls of the tongues !9 and grooves 18 frictionally bind. When so bound together, the complementary half handles are Wedge locked together in place on bail portion I 2 and may rotate thereon if desired.

To fabricate such ahalf 'handle in the mold structure requires at least a two-part mold each forming one half of the generally semi-circular exterior and the faoe |4-with the tapered groove forming core, or the same with the oppositely tapered tongue forming groove After molding each mold part may be pulled longitudnally in the direction to free the mold portion from the resulting half handle. This assumes taper is not provided on the handle.

When same is to be emboded, a three-piece mold may be used, the main portion being socketed for forming the desired exterior surface and the other two parts forming the face 14 with groove IG therein and groove IB forming core and tongue |9 forming groove. Then these two parts are pulled lengthwise and oppositely thereby exposing face M. Then a portion in the well of the main mold portion may eject the half handle laterally of said main mold portion. A two-piece mold with half the exterior and half the bore on each part can also be used. Molds of the two-piece and three-piece character suitable for phenol-condensation product molding arewell known, henoe are not illustrated heroin. i

For either type of half handle, molding With slip molding portions is. required byvreason of the tapered exterior character of said handles and always by reason of the restricted threat 20 and the reduced neck 2l, in order to eject the half handle or free it from said mold.

It is to be observed that to connect two complementary and. similar half `hand1es, it is merely necessary to invert one and then turn it end for end so that the small ends of the tongues confront the large ends of the looking grooves. Then, sliding both together or one. on' the other with the bail l2 in the resulting complete groove 16 serves to mount and connect the half handles upon the bail and together respectively." Jamming the wedge iormations together then looks the parts in these relationships.

While the invention has been. illustrated and described in great detail in the drawing and 5 foregoing description, the same is to be considered as illustrative and not restrictive in charaoter.

The several modifications described heroin, as 'well ;as others which will readily suggest themlO selves to persons skilled in` this art, all are considered to be within the broad scope of the invention, reference being had to the appended claims.

The invention claimed is: 1. A handle for a bail, including two substantially similar half handles, each having a.

,longitudinal bore therethrough, the half handles Whenass'ociated together forming a complete bore for bai'l aocommodation, each handle at one side of said bore: and in the confronting face 20 being provided with a looking tongue par'allel to the bore axis and substantially coextensive with the handle, there being a complementary 'locking groove parallel to the tongue and the bore in that face andspaoed equidistantfrom the bore axis and .at the opposite side thereof from said tongue, the tongue of one half handle seating in the looking groove of the other .half handle, each looking groove and tonguebeing' longi'- tudinally tapered, the two taperings being oppo- .30 sitely directed in each half handle and'identical.

2. A handle for peripheral embracement of and longitud'nal locking'upon.. a bail including 'two substantially similar half ?handleseach half handle having a face provided with a long-itudina groove positioned midway in that face and extending the full length of the half handle,`the grooves when the half handles are faced and locked together forming a bore forbail accommodation, each half handle at one side ofsaid 40 bore forming groove and spaced from said bore and the adjacent longitud'nal edge of the face including' longitudinally directed tongue means, substantially coextensive with the: half handle, said tongue means remote from said face having a greater transverse width than immediately adjacent the face to form a looking tongue thereon, said face having, opposite the tongue and spaced from the bore forming groove a like distance therefron as the tongue is spa'ced therefrom, a1o'cking groove parallel to the bore'grcove and the looking tongue and having a wall 'arrangeme'nt in transverse section substantially complementary to the tongue cross-section, 'the looking groove being but -slightly larger than the tongue for longitudinal slt fit association of the half handles and' frictional retention in handle formation about the ball, the looking tongue of one half handle being received by the looking groove of 'the other half handle and the lockingtongue ot the last mentioned half handle being received by the looking groove in the said last mentioned one half handle, each locking groove and tongue means being tapered longitudinally, the tapering in each half' handle being oppositely directed and identical ther-ein.
