FASTENING TOOL HANDLE Filed Jan. 20, 1955 Patented Mar. 13, 1934 FASTENHNG TOOL HANDLE Earl A. Litchfield, Montpelier, Ohio, assignor to Daniel W. Winzeler, Montpelier, Ohio Application January 20, 1933, Serial No. 652,7?

This invention relates to rigid metal terminal fittings for wood handles.

This invention has utility when incorporated in tubular reinforcements for joints between wood Furthermore, thesetongues 2, 3, are configured handles and the tool with which such handles are mounted.

Referring to the drawing:

Fig. 1 is a View of a blank hereunder;

Fig. 2 is a side View of the blank as formed into a tube;

Fig. 3 is a section on the line III-III, Fig. 1;

Fig. 4 is a detail view of the keying disk for assembly with the tube;

Fig. 5 is a fragmentary view of the assembly of the tube with the wood handle;

Fig. 6 is a section on the line VIVI, Fig. 5;

Fig. '7 is a distributed View of elements of the fastening, parts being broken away; and

Fig. 8 is a view of the assembled fastening with the handle, parts being broken away.

Body 1, a fiat sheet metal blank, is shown as havingtongues 2, 3, therefrom. Said tongues are shown as having marginal offsets orprojections 3 in the portions thereof away from the body 1.

to effect additional marginal reinforcement at ears or lugs 4, due to the increased effectiveness thereby given theoffset portions 3'. This blank is further provided with openings 5 near the free ends of thetongues 2, 3, and withbeads 6 as reinforcement means extending from the body 1 into therespective tongues 2, 3.

Thesebeads 6 are offset oppositely from theoffsets 3'. The body 1, remote from the tongues '2, 3, is provided with key portions orseats 7,

herein shown of dove-tailed form. In the shaping of the fiat blank 1 byweld 8 to formtube 9, theseats 7 are located diametrically of each other and in approximate alignment with the beads '6. Wood handles 10, in many tools such as shovels, forks, etc., have the portion thereof adjacent the tool of curved terminus form 11.

Over this curved terminus,tube 9 may be thrust with theopposing tongues 2, 3, of the flat general form to permit ready flexing clearance as to the inner orshorter tongue 3 and lack of material disturbance or resistance given by the offset projections 8'. With thistubular portion 9 assembled in position with the terminus 11 of thehandle 10, rollers 12, 13, havingconcave seats 14 conforming to thehandle 10 androot grooves 15 for clearing thebeads 6, may coact. This roll pair 12, 13, active along the handle from thetubular portion 9, is effective for embedding or anchoring theprojections 3 into the wood as a finished assembly in conforming thetongues 2, 3, with thewood handle 10.

Supplemental anchoring is effected by rivet 16 through the openings 5 in thetongues 2, 3. This reinforcement portion of the fastening for the wood handle as to a tool, is marginally effective for smooth exterior or surface continuity with thehandle 10, so that the workman, as gripping thehandle 10, may slide a hand along thehandle 10 over the free ends of thetongues 2, 3, without tendency to tear the flesh or wear the hand covering, from any irregularity. This is a feature of material importance to the tool operator. Themarginal portions 3, continuous even about the free ends of thetongues 2, 3, are the effective provisions in carrying out the utility of this fastening.

Disk 1'7 is shown with keying opening 18 as to a tool, and keying lugs orears 19, which are offset from the flat portion of thedisk 17, and 7 may register with theseats 7 in thetube end portion 9 at the terminus of thehandle 10. At such register position for thedisk 17, the keying opening 18 is aligned with the terminus of circular cross-section opening 20 in thehandle 10.Tool 21, say a shovel blade or other type of hand tool, may have seat 22 from which extendsstem 23, say of rectangular cross-section and tapered for driving into taperedcircular cross-section hole 20 in thehandle 10. This rectangularcrosssectional stem 23 may accordingly have key coaction with the opening 18 in thedisk 17 for holding thetool 21 against angular shifting relatively to thehandle 10, due to the fact that thedisk 17 is efiectively keyed with thetubular portion 9 anchored throughout the extent of thetongues 2, 3, with thehandle 10.

Furthermore, this disk assembly is one sealed and concealed by nipple ortrim 24 havingtransverse slot 25 riding overrib 26 at the seat 22. Thisnipple 24, in driving thestem 23 through the opening 18 and into thehandle 10, telescopes over thelugs 19 of thedisk 17 and comes into snug fitting position on thetubular portion 9. The assembled structure is accordingly one of rela tively light gage sheet steel for the effective strength thereof and is such a device as may be readily adoptd not only in factory production but in replacing handles for tools.

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

1. A tool fastening for a wood handle having a central terminal opening for the stem of the tool, said fastening comprising a tubular portion having opposing tongues and providing a seat for the handle, a stem keying disk keyed with the tubular portion, and a trim fitted-about the stem for concealing said keying disk in assembly with the tubular portion.

2. A wood handle having an axial opening in a terminus thereof, a tubular sheet metal body fitting the handle terminus and terminally provided with seat means, a disk having marginal seat means complementary to the body seat means for angularly anchoring the disk with the body, said disk centrally having a keying port registering with the axial opening of the handle, and a tool stem extending through the disk into the handle axial opening.

3. A reinforced Wood handle ferrule comprising a sheet metal body having a Weld-completed tubular tapered portion enlarging to terminate in tongues having offset margins, a tapered terminus wood handle fitting into the sheet metal tapered portion and adapted there to receive the stem of a tool axially of the tubular portion, said oifset margin adapted to be embedded into the Wood of the handle with the wood shielding the edges of the tongues throughout the entire extent of the tongues from the tubular portions, and a rivet through the handle and the tongues remote from the tapered tubular portion supplementing the anchoring of the metal body by the tongues aga nst longitudinal and angular loosening relatively to the Wood handle.
