Abstract
Abstract A broom for use in the game of curling has a handle and a sweeping head secured to one end of the handle. The head comprises a bundle of elongate fibres, means binding the fibres together to form the bundle, and means securing the bundle of fibres to the handle. A pouch surrounds the normally lower portion of the bundle of fibres, remote from the handle, and is formed of flexible sheet material having smooth non-binding inner and outer surfaces. Means are provided which tie the pouch to the binding means to prevent the pouch from slipping down the bundle, away from the handle. A flexible fabric cover is applied over the pouch and fibre bundle, and provides an outer surface suitable for contact with the ice surface during play of a curling game.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
250 words
A broom for use in the game of curling, having a handle and a sweeping head secured to one end of said handle, said head comprising: a bundle of elongate fibres; means binding said fibres together to form a bundle comprising a plurality of rows of cord stitching which pass through and around said fibres at the normally upper end of said fibre bundle adjacent to the handle; means securing said bundle of fibres to said handle; a pouch surrounding only a lower portion of said bundle of fibres remote from said handle but covering at least the lower third of said bundle, said pouch comprising flexible sheet material having smooth non-binding inner and outer surfaces, and extending around the lower end of said fibre bundle to form a pocket in which the fibres are completely surrounded and loosely encased, the sides of the pocket extending toward the handle of thE broom over at least one third of the lower portion of said fibre bundle; means holding said pouch on said broom head and preventing said pouch from slipping down said bundle away from said handle; and a flexible fabric cover applied over said pouch, fibres and bindings, and in direct contact with said smooth non-binding outer surface of said pouch so that the cover can slide freely relative to the pouch, said flexible fabric cover being bound to said broom handle, and providing an outer surface suitable for contact with the ice surface during play of a curling game.
Claim 2
Dependent Claim
250 words
A broom for use in the game of curling, having a handle and a sweeping head secured to one end of said handle, said head comprising: a bundle of elongate fibres; means binding said fibres together to form a bundle comprising a plurality of rows of cord stitching which pass through and around said fibres at the normally upper end of said fibre bundle adjacent to the handle; means securing said bundle of fibres to said handle; a pouch surrounding only a lower portion of said bundle of fibres remote from said handle but covering at least the lower third of said bundle, said pouch comprising flexible sheet material having smooth non-binding inner and outer surfaces, and extending around the lower end of said fibre bundle to form a pocket in which the fibres are completely surrounded and loosely encased, the sides of the pocket extending toward the handle of thE broom over at least one third of the lower portion of said fibre bundle; means holding said pouch on said broom head and preventing said pouch from slipping down said bundle away from said handle; and a flexible fabric cover applied over said pouch, fibres and bindings, and in direct contact with said smooth non-binding outer surface of said pouch so that the cover can slide freely relative to the pouch, said flexible fabric cover being bound to said broom handle, and providing an outer surface suitable for contact with the ice surface during play of a curling game.
Claim 3
Dependent Claim
36 words
A curling broom as defined in claim 1, wherein said means holding said pouch on said broom head comprises cord which passes through said pouch and is tied back to said means binding said fibres together.
Claim 4
Dependent Claim
26 words
A curling broom as defined in claim 2, wherein: adjoining edges of the sheet material forming said pocket are sewn together to provide improved shape retention.
Claim 5
Dependent Claim
65 words
A curling broom as defined in claim 2, wherein: said cord passes through the sides of said pouch and through said fibre bundle in a relatively loose manner so as to hold the pouch adjacent the fibre bundle and give the bundle and pouch substantially unitary motion during broom use, but not interfere with the natural flexing action and swinging motion of the broom head.
Claim 6
Dependent Claim
36 words
A curling broom as defined in claim 1, wherein: said means holding said pouch on said broom head comprises a strap formed of smooth, flexible sheet material attached to said pouch and fastened to said handle.
Claim 7
Dependent Claim
82 words
A curling broom as defined in claim 1, wherein said means holding said pouch on said broom head includes cord ties which pass through the sides of said pouch and through said fibre bundle from one side of the pouch to the other in a manner which is loose enough to permit relative movement between adjacent fibres and between the fibre bundle and the pouch, but which holds the pouch close to the fibre bundle and gives unitary motion thereto during use.
Claim 8
Dependent Claim
119 words
A curling broom as defined in claim 1, including: an insert tongue enclosed within and surrounded by said bundle of fibres and secured therein by said upper cord bindings, said insert tongue extending from said binding means down the broom head and away from said handle at least a major portion of the length of said broom head; and relatively loose stitching passing through opposite sides of said pouch, said fibre bundle and said tongue insert, said stitching acting to give the pouch, the fibre bundle and the tongue insert a unitary action during use and attaching said pouch to said tongue insert and upper cord bindings so as to prevent said pouch from sliding off said fibre bundle.
