Abstract
Abstract A roller skate wheel attachment which is removably attachable to a wheel at the axle thereof. The device includes a connector which removably affixes to the wheel axle and a rotary member which is rotable about the connector and which rotates when the wheel rotates. In one embodiment of the invention, the rotary member incorporates a switch which serves to alternately energize and de-energize lamps as the wheel rotates. In a second embodiment, the rotary member includes a reflecting surface to rotatively reflect light from exterior lighting sources when the skate wheel rotates.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
127 words
In a skate wheel attachment adapted to be removably affixed to a skate wheel at the axle thereof, the combination of A. a stationary socket associated concentrically with the wheel axle, 1. said socket being removably connected to the axle and nonrotating with respect thereto, said socket projecting outwardly with respect to said wheel to provide a cylindrical surface; B. a housing journalled on the socket at the cylindrical surface and rotatable about the socket, 1. said housing having inwardly projecting means which extend inwardly a sufficient distance to contact and engage to the skate wheel whereby the housing rotates when the wheel rotates; and C. light transmitting means contained within the housing 1. said light transmitting means directing light rays exteriorly of the skate wheel attachment.
Claim 2
Dependent Claim
127 words
In a skate wheel attachment adapted to be removably affixed to a skate wheel at the axle thereof, the combination of A. a stationary socket associated concentrically with the wheel axle, 1. said socket being removably connected to the axle and nonrotating with respect thereto, said socket projecting outwardly with respect to said wheel to provide a cylindrical surface; B. a housing journalled on the socket at the cylindrical surface and rotatable about the socket, 1. said housing having inwardly projecting means which extend inwardly a sufficient distance to contact and engage to the skate wheel whereby the housing rotates when the wheel rotates; and C. light transmitting means contained within the housing 1. said light transmitting means directing light rays exteriorly of the skate wheel attachment.
Claim 3
Dependent Claim
23 words
The invention of claim 1 wherein the said light transmitting comprises a reflecting surface, said reflecting surface being diametrically oriented within the housing.
Claim 4
Dependent Claim
39 words
The invention of claim 2 wherein the housing has a floor and the reflecting surface is formed to the configuration of a rib which projects outwardly from the floor, the said rib having sloping sidewalls for light reflecting purposes.
Claim 5
Dependent Claim
34 words
The invention of claim 3 wherein the transverse rib receives light from a source exterior of the housing and reflects the received light, the sloping sidewalls reflecting the reflected light as the housing rotates.
Claim 6
Dependent Claim
25 words
The invention of claim 1 and a magnet positioned within the socket in a stationary manner, said magnet removably securing the socket to the axle.
Claim 7
Dependent Claim
84 words
The invention of claim 1 wherein the said housing carries a plurality of pairs of electrical contacts means for selectively connecting each one of the contacts of a pair to its corresponding contact, a battery, an electrical circuit activated by the battery and a lamp which is energized when the electrical circuit is activated by the battery, the said electrical contacts serving to complete the circuit to energize the lamp when said connecting means connects one contact of a pair to its corresponding contact.
Claim 8
Dependent Claim
55 words
The invention of claim 6 wherein said connecting means includes a band having two portions, a first portion of said band being fabricated of electrically conductive material and a second portion of said band being fabricated of electrically non-conductive material, said band being peripherally arranged within the housing and having rotary motion within the housing.
