Abstract
Abstract Because barbeque forks tend to be rather unwieldy items a barbeque fork is provided which can be separated into a number of shorter pieces or lengths for storage and the pieces then assembled end to end by connecting means before use. Preferably such connecting means comprise a screw-threaded spigot on one piece and a corresponding screw-threaded socket on the adjacent piece. To avoid difficulties in unscrewing the connection means with greasy hands, however, when there are more than three pieces or sections, gripping means such as outwardly projecting lugs are provided the or each section which is not one containing the handle or the prongs. Also to assist in propping up the fork a supporting member, axially slidable along the shaft, can be provided, the supporting member comprises a pair of domed plates placed back to back and each plate having a number of outwardly projecting arms.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
131 words
A barbeque fork comprising a shaft, a handle at one end of said shaft, prongs for supporting food at the other end of said shaft, said shaft being capable of being separated into a number of shorter lengths for storage, connecting means for holding said lengths assembled end-to-end for use, said connecting means comprising a screw-threaded spigot formed by screw-threading on one end of one length and a corresponding internally screw-threaded socket formed in a collar joined on the end of an an adjacent length, and a flange attached to said end of said one length, said flange abutting said socket to limit the extent to which said screw-thread can enter said corresponding socket so that the end of said one length does not touch the end of said adjacent length.
Claim 2
Dependent Claim
131 words
A barbeque fork comprising a shaft, a handle at one end of said shaft, prongs for supporting food at the other end of said shaft, said shaft being capable of being separated into a number of shorter lengths for storage, connecting means for holding said lengths assembled end-to-end for use, said connecting means comprising a screw-threaded spigot formed by screw-threading on one end of one length and a corresponding internally screw-threaded socket formed in a collar joined on the end of an an adjacent length, and a flange attached to said end of said one length, said flange abutting said socket to limit the extent to which said screw-thread can enter said corresponding socket so that the end of said one length does not touch the end of said adjacent length.
Claim 3
Dependent Claim
52 words
A barbeque fork according to claim 1 in which there are at least three of said lengths; and in which one length carries said prongs, another length carries said handle, and the remaining length further comprises gripping means fixed thereto to assist the user to separate that length from an adjacent length.
Claim 4
Dependent Claim
19 words
A barbeque fork according to claim 2 in which said gripping means comprises a number of outwardly projecting lugs.
Claim 5
Dependent Claim
18 words
A barbeque fork according to claim 3 in which said lugs are integrally formed with said connecting means.
Claim 6
Dependent Claim
48 words
A barbeque fork according to claims 1, 2, 3, or 4 further comprising a supporting member axially slidable along at least part of the shaft, said supporting member comprising a pair of domed plates placed back-to-back and each having, in axial section, a number of outwardly projecting arms.
Claim 7
Dependent Claim
187 words
A barbeque fork comprising: a shaft separable into at least three lengths for storage, said lengths being assembled end-to-end for use, a handle at one end of said shaft when assembled for use, said handle being joined to one of said lengths, prongs for supporting food at the other end of said shaft, said prongs being attached to another of said lengths, connecting means for assembling the shafts end-to-end for use, said connecting means comprising a screw-threaded spigot formed by screw-threading at the end of one length and a corresponding internally screw-threaded socket formed in a collar joined on the end of an adjacent length, a flange attached to said end of said one length to limit the extent to which said screw-thread can enter said corresponding socket, said flange having a surface to abut said socket whereby the screw-threaded end of said one length does not touch the end of said adjacent length, and gripping means integrally formed with said collar attached to at least one of the remaining lengths of said shaft, to assist the user to separate said latter length from an adjacent length.
Claim 8
Dependent Claim
187 words
A barbeque fork comprising: a shaft separable into at least three lengths for storage, said lengths being assembled end-to-end for use, a handle at one end of said shaft when assembled for use, said handle being joined to one of said lengths, prongs for supporting food at the other end of said shaft, said prongs being attached to another of said lengths, connecting means for assembling the shafts end-to-end for use, said connecting means comprising a screw-threaded spigot formed by screw-threading at the end of one length and a corresponding internally screw-threaded socket formed in a collar joined on the end of an adjacent length, a flange attached to said end of said one length to limit the extent to which said screw-thread can enter said corresponding socket, said flange having a surface to abut said socket whereby the screw-threaded end of said one length does not touch the end of said adjacent length, and gripping means integrally formed with said collar attached to at least one of the remaining lengths of said shaft, to assist the user to separate said latter length from an adjacent length.
