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, these tongues 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 having tongues 2, 3, therefrom. Said tongues are shown as having marginal offsets or projections 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 the offset portions 3'. This blank is further provided with openings 5 near the free ends of the tongues 2, 3, and with beads 6 as reinforcement means extending from the body 1 into the respective tongues 2, 3.

These beads 6 are offset oppositely from the offsets 3'. The body 1, remote from the tongues '2, 3, is provided with key portions or seats 7,

herein shown of dove-tailed form. In the shaping of the fiat blank 1 by weld 8 to form tube 9, the seats 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 the opposing tongues 2, 3, of the flat general form to permit ready flexing clearance as to the inner or shorter tongue 3 and lack of material disturbance or resistance given by the offset projections 8'. With this tubular portion 9 assembled in position with the terminus 11 of the handle 10, rollers 12, 13, having concave seats 14 conforming to the handle 10 and root grooves 15 for clearing the beads 6, may coact. This roll pair 12, 13, active along the handle from the tubular portion 9, is effective for embedding or anchoring the projections 3 into the wood as a finished assembly in conforming the tongues 2, 3, with the wood handle 10.

Supplemental anchoring is effected by rivet 16 through the openings 5 in the tongues 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 the handle 10, so that the workman, as gripping the handle 10, may slide a hand along the handle 10 over the free ends of the tongues 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. The marginal portions 3, continuous even about the free ends of the tongues 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 or ears 19, which are offset from the flat portion of the disk 17, and 7 may register with the seats 7 in the tube end portion 9 at the terminus of the handle 10. At such register position for the disk 17, the keying opening 18 is aligned with the terminus of circular cross-section opening 20 in the handle 10. Tool 21, say a shovel blade or other type of hand tool, may have seat 22 from which extends stem 23, say of rectangular cross-section and tapered for driving into tapered circular cross-section hole 20 in the handle 10. This rectangular crosssectional stem 23 may accordingly have key coaction with the opening 18 in the disk 17 for holding the tool 21 against angular shifting relatively to the handle 10, due to the fact that the disk 17 is efiectively keyed with the tubular portion 9 anchored throughout the extent of the tongues 2, 3, with the handle 10.

Furthermore, this disk assembly is one sealed and concealed by nipple or trim 24 having transverse slot 25 riding over rib 26 at the seat 22. This nipple 24, in driving the stem 23 through the opening 18 and into the handle 10, telescopes over the lugs 19 of the disk 17 and comes into snug fitting position on the tubular 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.
