Abstract
Abstract The hand tool comprises a working head, such as a spade blade or a fork, welded to a tubular tang-forming portion of a handle, the tang-forming portion comprising two telescoped tubes which have been bent to a curved shape and flattened to an oval crosssection over the curved part and up to one end. The major axis of the oval section lies in the plane of curvature, and the end of the tubes is cut off obliquely in a plane normal to the plane of curvature to provide an end surface of elongate oval shape which is welded around its periphery to a flat surface of the working head.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
126 words
A hand tool comprising a working head, a handle secured to a substantially flat surface of said working head, a tang-forming portion of the handle adjacent the head being tubular and of oval cross-section and having a flat oblique oval end surface of which the major axis has a substantially greater length than that of the oval cross-section, said end surface being welded to the flat surface of the head, and wherein the said tang-forming portion of the handle is curved in a plane containing the major axis of the oval end surface and adjoining a main portion of the handle which thus extends at an angle to the head less than that between the head and the tang-forming portion of the handle immediately adjacent thereto.
Claim 2
Dependent Claim
126 words
A hand tool comprising a working head, a handle secured to a substantially flat surface of said working head, a tang-forming portion of the handle adjacent the head being tubular and of oval cross-section and having a flat oblique oval end surface of which the major axis has a substantially greater length than that of the oval cross-section, said end surface being welded to the flat surface of the head, and wherein the said tang-forming portion of the handle is curved in a plane containing the major axis of the oval end surface and adjoining a main portion of the handle which thus extends at an angle to the head less than that between the head and the tang-forming portion of the handle immediately adjacent thereto.
Claim 3
Dependent Claim
30 words
A hand tool according to claim 3 wherein the tang-forming portion of the handle comprises two tubular members fitting closely one within the other, and both welded to the head.
Claim 4
Dependent Claim
39 words
A hand tool according to claim 2 wherein one of said tubular members extends beyond the other in a direction away from the head, a main portion of the handle being joined to said one of the tubular members.
Claim 5
Dependent Claim
17 words
A hand tool according to claim 1 wherein the head is a spade blade of sheet steel.
Claim 6
Dependent Claim
13 words
A hand tool according to claiM 1 wherein the head is a fork.
Claim 7
Dependent Claim
75 words
A hand tool according to claim 5 wherein the fork comprises a U shaped member defining two tines and a footrest, two further tines disposed between the first mentioned tines, and a plate flanked by said further tines and lying substantially in the plane of the four tines, said U shaped member, said further tines and said plate being welded to one another, said plate providing the flat surface to which the handle is secured.
Claim 8
Independent Claim
122 words
A method of manufacturing a hand tool which comprises fitting together two tubes telescopically, bending the two telescoped tubes to form a curved tang-portion of the handle of the tool, flattening the bent tubes to give them an oval cross-section, the major axis of the oval lying in the plane of symmetry of the telescoped bent tubes, cutting one end of the telescoped tubes in a plane perpendicular to the said plane of symmetry and obliquely to the axis of the tubes at the cut end thereof, welding the cut ends of the telescoped tubes to a flat surface of a working head of the tool, and fixing a hand grip to a shaft forming an extension of one of said tubes.
Claim 9
Independent Claim
122 words
A method of manufacturing a hand tool which comprises fitting together two tubes telescopically, bending the two telescoped tubes to form a curved tang-portion of the handle of the tool, flattening the bent tubes to give them an oval cross-section, the major axis of the oval lying in the plane of symmetry of the telescoped bent tubes, cutting one end of the telescoped tubes in a plane perpendicular to the said plane of symmetry and obliquely to the axis of the tubes at the cut end thereof, welding the cut ends of the telescoped tubes to a flat surface of a working head of the tool, and fixing a hand grip to a shaft forming an extension of one of said tubes.
Claim 10
Dependent Claim
71 words
A method according to claim 7 which comprises the initial step of forming the working head as a fork by bending a bar into a U shape to form the footrest and two tines of a fork, welding said footrest and two further tines along three sides respectively of a flat plate, said plate itself, or together with the footrest and further tines, forming said flat surface of the working head.
