Vibrating spray apparatus and method of spraying

Claim 2

A liquid spray device adapted to produce a spray of substantially uniform density having a generally curvilinear pattern, comprising in combination: an elongated flexible spray tube fixedly mounted at one end and free at the other end and having a restricted outlet at said free end thereof; liquid supply means connected to said tube adjacent said fixed end and adapted to supply liquid thereto to be sprayed from said outlet; and a motion transmitting device associated with said tube and adapted to impart vibrations thereto at a resonant frequency in a direction and of sufficient magnitude to cause the outlet end of said tube to describe an orbital path about a fixed stationary axis through the fixed end of said spray tube whereby liquid being emitted from said outlet is thrown outwardly in the form of discrete particles to produce a predetermined curvilinear spray pattern.

Claim 3

The device claimed in claim 1 wherein the restricted outlet consists of at least two orifices.

Claim 4

The device claimed in claim 2 wherein at least a portion of said spray tube adjacent said free end is flexible.

Claim 5

A liquid spray device adapted to produce a spray having a substantially uniform density and of a generally circular pattern, comprising in combination: a generally perpendicularly disposed, elongated, flexible spray tube fixedly mounted at the inlet end thereof and free at the outlet end; liquid supply means connected to said tube adjacent the fixed end thereof and adapted to supply liquid thereto to be sprayed from said outlet; and a motion producing device associated with said tube and adapted to impart vibrations thereto at a resonant frequency in a direction and with sufficient magnitude to cause the outlet end of said tube to move in a generally circular orbital path about a fixed stationary axis through the fixed end of the spray tube whereby liquid being emitted from said outlet is tHrown therefrom in the form of discrete particles to produce a predetermined circular spray pattern.

Claim 6

A liquid spray device adapted to produce a spray having a substantially uniform density and of a generally circular pattern, comprising in combination: a generally perpendicularly disposed, elongated, flexible spray tube fixedly mounted at the inlet end thereof and free at the outlet end; liquid supply means connected to said tube adjacent the fixed end thereof and adapted to supply liquid thereto to be sprayed from said outlet; and a motion producing device associated with said tube and adapted to impart vibrations thereto at a resonant frequency in a direction and with sufficient magnitude to cause the outlet end of said tube to move in a generally circular orbital path about a fixed stationary axis through the fixed end of the spray tube whereby liquid being emitted from said outlet is tHrown therefrom in the form of discrete particles to produce a predetermined circular spray pattern.

Claim 7

The device claimed in claim 4 wherein said restricted outlet consists of at least two separate small diameter orifices.

Claim 8

The device claimed in claim 5 wherein said restricted outlet consists of four separate small diameter tubes each bent slightly adjacent the ends thereof so as to be non-parallel with the major axis of the device.

Claim 9

The device claimed in claim 4 wherein said motion producing device is mounted outside the vertical axis of said spray tube and consists of a rotating off-center weight.

Claim 10

The device claimed in claim 4 including a motor and off-center weight which are positioned in misalignment with the axis of said tube.

Claim 11

A liquid spray device adapted to produce a spray having a substantially uniform density and of a generally circular pattern, comprising in combination: a generally perpendicularly disposed, elongated flexible spray tube fixedly mounted at the inlet end thereof and free at the outlet end; liquid supply means connected to said tube adjacent the fixed end thereof and adapted to supply liquid thereto to be sprayed from said outlet; and a motion producing device associated with said tube and adapted to impart vibrations thereto at a resonant frequency in a direction and with sufficient magnitude to cause the outlet end of said tube to move in a generally circular orbital path about a fixed stationary axis through the fixed end of the spray tube whereby liquid being emitted from said outlet is thrown therefrom in the form of discrete particles to produce a predetermined circular spray pattern, valve means being provided adjacent the device wherein valve means are provided adjacent the fixedly mounted end of the spray tube, said valve means being sensitive to said vibrations to remain open for permitting liquid flow therethrough and closing only when said vibrations cease to prevent such flow.

Claim 12

A liquid spray device adapted to produce a spray having a substantially uniform density and of a generally circular pattern, comprising in combination: a generally perpendicularly disposed, elongated flexible spray tube fixedly mounted at the inlet end thereof and free at the outlet end; liquid supply means connected to said tube adjacent the fixed end thereof and adapted to supply liquid thereto to be sprayed from said outlet; and a motion producing device associated with said tube and adapted to impart vibrations thereto at a resonant frequency in a direction and with sufficient magnitude to cause the outlet end of said tube to move in a generally circular orbital path about a fixed stationary axis through the fixed end of the spray tube whereby liquid being emitted from said outlet is thrown therefrom in the form of discrete particles to produce a predetermined circular spray pattern, valve means being provided adjacent the device wherein valve means are provided adjacent the fixedly mounted end of the spray tube, said valve means being sensitive to said vibrations to remain open for permitting liquid flow therethrough and closing only when said vibrations cease to prevent such flow.
