Feb. 18', 1936. D. w. wlNzELER FASTENING FOR THE HANLES OF TOOL-S Filed lJune 14, 1954 Patented Feb. 18, 1936 fw UNITED STATES PATENT OFFICE l Claim.

This invention relates to means for assembling metallic portions or sections with handles.

This invention has utility when incorporated with wood handles and collapsed cylindrical anf chorage therewith of tool portions, extensions,

trims or ferrules.

Referring to the drawing: Fig. 1 is a side view, with parts broken away, of an embodiment of the invention as a trim, 10 say for a fork handle, wherein the trim has a pair of tongues;

Fig. 2 is a fragmentary view of an embodiment of the invention in a tool having a tongue therefrom along the handle;

Fig. 3 is a section on the line III-III, Fig. 2;

Fig. 4 is an embodiment of the invention in association with metallic or sheet metal sleeve portions as a trim for a wood handle in the extensions from the grip of a D;

20 Fig. 5 is a view of an embodiment of the invention wherein the metal extension from the tool is of split sleeve form;

Fig. 6 is a view of the die for effecting a sequence of collapsing or diameter reduction assembly of the embracing cylinder herein for effecting anchorage;

Fig. 7 is a section on the line VII-VII, Fig. l;

Fig. 8 is a section on the line VIII-VIII, Fig. 4; and 30 Fig. 9 is a section on the line IX-IX, Fig. 5.

Wood handle cylindrical portion I is shown with wood tapered portion 2 with which there may be telescopic assembly of ferrule tapering sleeve portion 3 having tongues 4, 5, therefrom. At this telescopic assembly, loose ring 6 may be slipped to position in the general fitting relation of the tongues 4, 5, with the cylindrical portion I of the wood handle, whether or not the tongues 4, 5, have been pre-formed to the handle I or formed therewith after the telescopic assembly. Even in the latter instance, with offset marginal portions 'I embedded in the wood handle I as anchorage, there may be supplemental reinforcement in changing the relative diameter of the ring 6 as to the wood I and tongue free termini. This herein may be effected by bringing the assembly with the loose ring 6 into position over die 8 having guides 9 rising therefrom to determine initial squeezing of the ring 6 to a reduced diameter, preferably less than the original diameter I plus the thickness of the ring 6 thereabout, now of oval form.

In this position upon the block or die 8, companion die IIJ with guide way II for the guides 9 may approach this die. 8 and at this press Cil sure action. In the suggested selection for dimension hereunder, there is supplemental embedding of the embraced portion of the free ends of the tongues, in that the ring 6 forms a partial seating thereinto compensated to some extent by the tongue embeddings being increased at such region into the wood, while between the tongues there is partial embedding of the ring with the wood. This embracing is a reinforcement for the wood I as well as eiecting this anchoring in a smooth relation for the handle so that the operator is not subjected to wound the hand or tearing of hand covering in the normal operation of the tool as a fork or shovel. As this anchorage is completed, assembly therewith of tool I2 as a fork may be had.

Whether lor not the wood I be of a reduced diameter or have tapered portion 2, there may be thrusting of the terminus I into socket, say in shovel I3. This shovel o-r tool blade I3 is shown with trim or tongue I4 therefrom seating along the handle I. Herein ring I5 may work its own seat partially into the free end of this tongue I4 as this ring is collapsed into the embedding assembly with the wood I in a manner analogous to that of the ring 6.

In the instance of D-handle grip I6 having sheet metal shield portions Il in which may extend to a greater or less extent, wood fork portions I8 from the handle I, there may be anchorage assembly through collapsible cylindrical ring or sleeve I9 analogous to the sleeve or rings 6, I5, with the collapsing eiected in similar manner for forming the seat on the portions .of the sheet metal forks I'I and increasing their embedding in the wood handle I. This is an effective reinforcement against any tendency of the split eX- tension from the fork at the D to break.

vTapered wood handle portion 29 (Fig. 5) is shown of somewhat greater extent than the tapered portion 2 in Fig. 1. Taper ferrule portion 2| may be a forming of sheet metal from the tool approximating a split sleeve. Collapsible reinorcing ring 22 is herein shown extending longitudinally along the handle I beyond the terminus of the sheet metal portion 2 I, and in this respect differs from the rings or sleeves 6, I5, I9. However, the collapsing is effected in a similar manner for seat forming and at the pressure ancho-rage therewith provides frictional effective assembly.

What is claimed and it ls desired to secure by Letters Patent is:

A handle for a tool, a sheet metal circumferentially incomplete portion in seating assembly with the handle, and an annularly complete ring' embracing the handle and sheet metal portion at said seat as a telescopic sleeve providing circumferential contracting means embedding the sheet metal portion with the handle, whereby the seat in the handle is formed for the sheet metal portion by contracting of the annular ring.
