Abstract

Abstract A fixture for simulating falling snow has a catch basin where the simulated snow is accumulated, a power operated pump for withdrawing the simulated snow particles from the catch basin and a distributing conduit into which the simulated snow is pumped and from which individual particles are ejected so as to flutter downwardly back to the catch basin. To make certain that the particles act separately and in a natural fashion, a separate air inlet is provided adjacent the pump intake into which an abundance of fresh air is drawn for ultimate mixing with simulated snow particles preventing the particles from sticking together during the travel through the distributor pipe and ultimate ejection from it.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 216 words
A fixture for simulating falling snow particles comprising a reservoir of individual simulated snow particles forming a catch basin with a wall structure sloping laterally inwardly toward a lowermost area, said particles being in quantity forming a mass in said catch basin with a constantly present upper surface above said lowermost area, a pump, a motor having an operating connection to the pump, a distributor conduit connected to the outlet side of the pump, said distributor conduit having constantily open particle outlet means at a fixed location elevated relative to a supporting surface and substantially in vertical alignment with said catch basin, a pump intake conduit of substantially uniform size having a particle inlet means emersed in said mass at a location adjacent said lowermost area of the catch basin and below said upper surface, and a constantly open pure air intake of fixed size in said intake conduit intermediate said particle inlet means and the pump, said air intake having a fixed position exteriorly with respect to said catch basin and below said upper surface, said pure air intake is a port exceeding the particle inlet means in size and is located at a level below said upper surface of the mass of particles and at substantially the same level as said particle inlet means.
Claim 2
Dependent Claim 216 words
A fixture for simulating falling snow particles comprising a reservoir of individual simulated snow particles forming a catch basin with a wall structure sloping laterally inwardly toward a lowermost area, said particles being in quantity forming a mass in said catch basin with a constantly present upper surface above said lowermost area, a pump, a motor having an operating connection to the pump, a distributor conduit connected to the outlet side of the pump, said distributor conduit having constantily open particle outlet means at a fixed location elevated relative to a supporting surface and substantially in vertical alignment with said catch basin, a pump intake conduit of substantially uniform size having a particle inlet means emersed in said mass at a location adjacent said lowermost area of the catch basin and below said upper surface, and a constantly open pure air intake of fixed size in said intake conduit intermediate said particle inlet means and the pump, said air intake having a fixed position exteriorly with respect to said catch basin and below said upper surface, said pure air intake is a port exceeding the particle inlet means in size and is located at a level below said upper surface of the mass of particles and at substantially the same level as said particle inlet means.
Claim 3
Dependent Claim 26 words
A fixture for simulating falling snow as in claim 1 wherein the pure air intake is a port opening through the side of the intake conduit.
Claim 4
Dependent Claim 36 words
A fixture for simulating falling snow as in claim 1 wherein the particle inlet means comprises a plurality of upwardly facing separate openings spaced from each other adjacent said lowermost area and surrounding the distributor conduit.
Claim 5
Dependent Claim 42 words
A fixture for simulating falling snow particles as in claim 1 wherein the distributor conduit is a vertically extending tube with a particle outlet opening at the top and a downwardly directed deflector mounted on the tube over said particle outlet opening.
Claim 6
Dependent Claim 28 words
A fixture according to claim 1 wherein said simulated snow particles comprise a foamed synthetic plastic resin in the form of beads and a mixture of powdered talc.
Claim 7
Dependent Claim 33 words
A fixture according to claim 5 wherein the particles comprise a mixture of foam polystyrene beads and powdered talc in proportions of about one part talc to 40 parts foamed polystyrene by weight.
Claim 8
Dependent Claim 222 words
A fixture for simulating falling snow particles comprising a reservoir of individual simulated snow particles forming a catch basin with a wall structure sloping laterally inwardly toward a lowermost area, said particles being in quantity forming a mass in said catch basin with an upper surface above said lowermost area, a pump, a motor having an operating connection to the pump, a distributor conduit connected to the outlet side of the pump, said distributor conduit having particle outlet means at a location elevated relative to a supporting surface and substantially in vertical alignment with said catch basin, a pump intake conduit having a particle inlet means adjacent said lowermost area of the catch basin and below said upper surface, and a pure air intake in said conduit intermediate said particle inlet means and the pump, said pure air intake being located exteriorly with respect to said catch basin, the distributor conduit being a vertically extending tube with a particle outlet opening at the top and a downwardly directed deflector mounted on the tube over said particle outlet opening, and wherein said tube extends to a position of support on said supporting surface and there is a stand at the lower end of said tube for laterally supporting said tube on the supporting surface and said catch basin is carried by said tube.
Claim 9
Dependent Claim 222 words
A fixture for simulating falling snow particles comprising a reservoir of individual simulated snow particles forming a catch basin with a wall structure sloping laterally inwardly toward a lowermost area, said particles being in quantity forming a mass in said catch basin with an upper surface above said lowermost area, a pump, a motor having an operating connection to the pump, a distributor conduit connected to the outlet side of the pump, said distributor conduit having particle outlet means at a location elevated relative to a supporting surface and substantially in vertical alignment with said catch basin, a pump intake conduit having a particle inlet means adjacent said lowermost area of the catch basin and below said upper surface, and a pure air intake in said conduit intermediate said particle inlet means and the pump, said pure air intake being located exteriorly with respect to said catch basin, the distributor conduit being a vertically extending tube with a particle outlet opening at the top and a downwardly directed deflector mounted on the tube over said particle outlet opening, and wherein said tube extends to a position of support on said supporting surface and there is a stand at the lower end of said tube for laterally supporting said tube on the supporting surface and said catch basin is carried by said tube.
