Abstract

Abstract This invention provides a curling game including a smooth, flat surface on which a target area is painted. Playing pieces are conveyed by a conveyor between the flat surface and flush therewith at a speed which is manually variable. Recessed in the flat surface between the conveyor and the target is a disk of which the top surface is flush with the flat surface. The disk can be swivelled about its centre and has thread-like, parallel entraining means adapted to change the angle of travel of a playing piece whenever the direction of the entraining means differs from the direction of travel.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 179 words
A curling game comprising: a smooth, elongated flat surface having a target area, endless conveyor means adjacent an edge of said flat surface and having one reach substantially co-planar with said flat surface, drive means adapted to move said one reach toward said flat surface in the general direction of said target area, a circular part of said flat surface being capable of angular movement about its center with respect to the remainder of said flat surface while remaining flush with the remainder of said flat surface, said circular part being situated generally between said endless conveyor means and said target area, and a plurality of spaced-apart, parallel entraining elements fixed to said circular part such that the direction of said elements with respect to the remainder of said flat surface can be changed through the angular movement of said circular part, whereby a playing piece propelled across said elongated flat surface toward said target area by said endless conveyor means traverses said entraining elements such that its direction of movement responds to the angulation of said entraining elements.
Claim 2
Dependent Claim 179 words
A curling game comprising: a smooth, elongated flat surface having a target area, endless conveyor means adjacent an edge of said flat surface and having one reach substantially co-planar with said flat surface, drive means adapted to move said one reach toward said flat surface in the general direction of said target area, a circular part of said flat surface being capable of angular movement about its center with respect to the remainder of said flat surface while remaining flush with the remainder of said flat surface, said circular part being situated generally between said endless conveyor means and said target area, and a plurality of spaced-apart, parallel entraining elements fixed to said circular part such that the direction of said elements with respect to the remainder of said flat surface can be changed through the angular movement of said circular part, whereby a playing piece propelled across said elongated flat surface toward said target area by said endless conveyor means traverses said entraining elements such that its direction of movement responds to the angulation of said entraining elements.
Claim 3
Dependent Claim 20 words
The invention claimed in claim 1, which further includes means for depositing a playing piece on said endless conveyor means.
Claim 4
Dependent Claim 44 words
The invention claimed in claim 2, in which said flat surface is substantially rectangular, in which said circular part is a disc recessed in the flat surface, and in which said entraining elements are threads strung along and against the surface of said disc.
Claim 5
Dependent Claim 37 words
The invention claimed in claim 3, in which the target area is located at one end of said rectangular surface, and in which the endless conveyor means is located adjacent the other end of said rectangular surface.
Claim 6
Dependent Claim 48 words
The invention claimed in claim 4, in which said endless conveyor means comprises a plurality of resilient closed loop elements arranged side-by-side around two parallel, spaced-apart shafts, one shaft being mounted for free rotation, and manual means for rotating the other shaft at a controlled rate of speed.
Claim 7
Dependent Claim 35 words
The invention claimed in claim 5, in which said one shaft is adjacent said other end of the elongated rectangle, and has indicator means for indicating the approximate speed of rotation of said one shaft.
Claim 8
Dependent Claim 96 words
The invention claimed in claim 6, in which said indicator means includes a flexible elongated member extending axially from one end of said one shaft and attached thereto, weight means on the outer end of the elongated member, and stationary scale means adjacent said elongated member, whereby an increasing rate of rotation tends to fling the weight means centrifugally outward with greater force, thus bending the elongated member to a greater extent as the weight means spins around the axis of said one shaft, the trajectory of the spinning weight means passing adjacent the scale means.
