Abstract
Abstract An improved agitator for a coin hopper having a rotatable pinwheel includes a hub mounted to the pinwheel and a plurality of elongated, longitudinally resilient blades projecting radially outward from the hub. The hub is preferably made of neoprene or other flexible material, and is mounted to the center of the plate so that the two rotate together. The blades are preferably made of spring steel or similar material and are not themselves attached to the pinwheel, but are embedded in the hub. The blades have hard, low friction surfaces, and longitudinally yield upon impact with the coins in the hopper and act to stir the coins and urge them into coin receiving slots on the pinwheel.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
104 words
A coin hopper comprising a rotatable pinwheel adapted to position coins along a peripheral portion of the wheel; a hub constructed of a material having a flexible surface and mounted to the pinwheel, and a plurality of elongated, longitudinally resilient blades extending from the hub towards the peripheral portion and having a relatively hard, low friction surface, the blades being oriented transversely to the pinwheel and having a height greater than the thickness of the coins, whereby the blades agitate the coins in the hopper during rotation of the pinwheel to facilitate the positioning of the coins on the peripheral portion of the pinwheel.
Claim 2
Dependent Claim
104 words
A coin hopper comprising a rotatable pinwheel adapted to position coins along a peripheral portion of the wheel; a hub constructed of a material having a flexible surface and mounted to the pinwheel, and a plurality of elongated, longitudinally resilient blades extending from the hub towards the peripheral portion and having a relatively hard, low friction surface, the blades being oriented transversely to the pinwheel and having a height greater than the thickness of the coins, whereby the blades agitate the coins in the hopper during rotation of the pinwheel to facilitate the positioning of the coins on the peripheral portion of the pinwheel.
Claim 3
Dependent Claim
15 words
A coin hopper according to claim 1 wherein the blades are constructed of a metal.
Claim 4
Dependent Claim
159 words
A coin hopper comprising a rotatable pinwheel having a peripheral portion for the positioning of coins therealong, a hub mounted concentrically with respect to the pinwheel and constructed of a flexible material, a plurality of blades having first ends embedded in the hub and second ends proximate the peripheral portion of the pinwheel, the hub extending in a radial direction approximately one-third of the distance from the center of the hub to said second ends, the blades being constructed of metal and being longitudinally resilient, having a height greater than the height of an individual coin in the hopper and being oriented substantially perpendicular to the pinwheel and means for imparting rotation to the hub when the pinwheel rotates, whereby coins in the hopper are agitated by the blades, urged towards the peripheral portion of the pinwheel and oriented generally parallel to the pinwheel to increase the number of coins positioned along the peripheral portion as the pinwheel rotates.
Claim 5
Dependent Claim
159 words
A coin hopper comprising a rotatable pinwheel having a peripheral portion for the positioning of coins therealong, a hub mounted concentrically with respect to the pinwheel and constructed of a flexible material, a plurality of blades having first ends embedded in the hub and second ends proximate the peripheral portion of the pinwheel, the hub extending in a radial direction approximately one-third of the distance from the center of the hub to said second ends, the blades being constructed of metal and being longitudinally resilient, having a height greater than the height of an individual coin in the hopper and being oriented substantially perpendicular to the pinwheel and means for imparting rotation to the hub when the pinwheel rotates, whereby coins in the hopper are agitated by the blades, urged towards the peripheral portion of the pinwheel and oriented generally parallel to the pinwheel to increase the number of coins positioned along the peripheral portion as the pinwheel rotates.
Claim 6
Dependent Claim
79 words
An agitator for use with a coin hopper having a rotatable pinwheel adapted to position coins in coin receiving slots on its peripheral portion comprising: a hub portion of relatively small diameter mounted to the center of said pinwheel, said hub having a flexible surface; and a plurality of longitudinally resilient blades attached to and extending radially outward from said hub portion so that they do not themselves contact said pinwheel, said blades having a hard, low friction surface.
Claim 7
Dependent Claim
79 words
An agitator for use with a coin hopper having a rotatable pinwheel adapted to position coins in coin receiving slots on its peripheral portion comprising: a hub portion of relatively small diameter mounted to the center of said pinwheel, said hub having a flexible surface; and a plurality of longitudinally resilient blades attached to and extending radially outward from said hub portion so that they do not themselves contact said pinwheel, said blades having a hard, low friction surface.
Claim 8
Dependent Claim
15 words
The agitator of claim 4 wherein said hub includes a plurality of radially extending lobes.
Claim 9
Dependent Claim
13 words
The agitator of claim 5 wherein said blades are attached to said lobes.
Claim 10
Dependent Claim
24 words
The agitator of claim 6 wherein said lobes extend approximately one-third of the distance from said center to the radial ends of said blades.
Claim 11
Dependent Claim
11 words
The agitator of claim 6 having three lobes and three blades.
Claim 12
Dependent Claim
30 words
The agitator of claim 4 wherein said blades are tapered from a maximum height at their point of attachment to said hub, to a minimum height at their radial-most end.
Claim 13
Dependent Claim
18 words
The agitator of claim 9 wherein said minimum height is approximately equal to the thickness of two coins.
