Abstract
Abstract An amusement arrangement includes an inclined slide and a fluid supply means to supply lubricating fluid upon the slide. A sled is fabricated of a lighter material than the lubricating fluid and is adapted to ride in the slide. Brake means are provided to coact between the sled and the slide to control the sliding speed of sled on the slide by selective frictional contact therewith.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
113 words
An amusement arrangement comprising an inclined slide, a fluid supply means to supply lubricating fluid upon said slide, a sled fabricated of a lighter material than said lubricating fluid and adapted to ride in said slide, and brake means coacting between said sled and said slide to control the sliding speed of said sled on said slide by selective rolling motion of said sled and wherein said slide has inwardly projecting edges to prevent said sled from jumping out of said slide and said brake means includes the underside of said edges and juxtapositioned surfaces on said sled which are placed in selective mutual frictional contact by selective rolling motion of the sled.
Claim 2
Dependent Claim
113 words
An amusement arrangement comprising an inclined slide, a fluid supply means to supply lubricating fluid upon said slide, a sled fabricated of a lighter material than said lubricating fluid and adapted to ride in said slide, and brake means coacting between said sled and said slide to control the sliding speed of said sled on said slide by selective rolling motion of said sled and wherein said slide has inwardly projecting edges to prevent said sled from jumping out of said slide and said brake means includes the underside of said edges and juxtapositioned surfaces on said sled which are placed in selective mutual frictional contact by selective rolling motion of the sled.
Claim 3
Dependent Claim
33 words
Amusement arrangement as recited in claim 1 wherein said sled has a seat, recess means for receiving the slider''s heels and control bar means for permitting the slider to make rolling body movements.
Claim 4
Dependent Claim
19 words
Amusement arrangement according to claim 2 wherein said control bar means includes a pair of side folding hand-holding bars.
Claim 5
Dependent Claim
42 words
Amusement arrangement as recited in claim 2 wherein said sled is flexible so that a backward pull upon said control bar will cause selective engagement of the front portion of said sled with the underside of said projecting edges of said slide.
Claim 6
Dependent Claim
16 words
Amusement arrangement as recited in claim 1 wherein the sled is constructed of a foam material.
Claim 7
Dependent Claim
36 words
Amusement arrangement as recited in claim 1 wherein the slide and sled have the same selected sectional curvature and that the lubricating means includes fluid discharge tubes on both sides of said slide throughout its length.
Claim 8
Dependent Claim
21 words
Amusement arrangement as recited in claim 6 wherein the sled has a hollowed out body, the stern portion thereof is open.
Claim 9
Dependent Claim
51 words
Amusement arrangement as recited in claim 1 wherein said sled is selectively dimensioned so that its two outer vertical edges are selectively spaced from the juxtapositioned vertical walls of said slide to maintain a vertical lubricating film between said sled and said slide whereby to increase the speed of said sled.
Claim 10
Dependent Claim
59 words
Amusement arrangement as recited in claim 8 wherein said inwardly projecting edges of said slide are selectively dimensioned so that they are selectively spaced from the top surface of said sled to maintain a horizontal liquid film therebetween whereby to effect a cooling of the braking surfaces between said sled and said slide after rolling motions of said sled.
Claim 11
Dependent Claim
56 words
Amusement arrangement as recited in claim 1 wherein said fluid supply means directs lubrication fluid along and above said sled when said sled is disposed upon said slide whereby to increase the speed of said sled and to effect cooling of the braking surfaces between said sled and said slide after rolling motions of said sled.
