Abstract
Abstract An extension spray device for aerosol cans having a crimped-cap closure comprises a can holder that grips the periphery of the closure cap, a spray member to engage the can control valve stem and convey fluid from the can to a lateral spray nozzle, an extension tube connecting a remote handle to the aerosol can holder, a wedge to force the spray member against the valve stem to dispense fluid from the can and a line attached to the wedge carried within the extension tube to move the wedge from the handle. The extension tube connection to the can holder can be moveable so that the spray can angle can be varied relative to the extension tube and handle.

Claim 1
Independent Claim
289 words
An extension spray device for remotely supporting and operating a conventional aerosol can having a crimped-cap closure with a moveable tubular control valve stem extending centrally out from said closure which comprises: a spray member comprising a body portion a nozzle extending laterally therefrom, a dished coupling depending from said body portion, and an L-shaped bore in the body portion joining said nozzle to said coupling; can holding means comprising: a cylindrical member, a transverse web portion at one end of the cylindrical member, the opposite end thereof having gripper means to grip the crimped-cap closure of an aerosol can, a lateral opening in said cylindrical member, and a hinge adjacent said lateral opening connecting said spray member body portion to said cylindrical member holding said nozzle in position to discharge through said lateral opening, valve stem actuation means comprising: a groove in the surface of said spray member body portion opposite to said dished coupling, the distance between the base of said groove and the undersurface of said transverse web portion of said can holding means progressively decreasing rearwardly of said nozzle, a wedge member positioned in said groove and engaging said undersurface, spring means biasing said wedge member toward said nozzle, and a line fastened to said wedge member by which it may be pulled along said groove away from said nozzle; a tubular extension having first and second ends connected at its first end to said can holding means, said actuating means line extending along said extension member internally thereof, a handle attached to the second end of said extension member, and lever means carried by said handle connected to said line to enable said wedge member to be moved by movement of said lever means.

Claim 10
Dependent Claim
215 words
In an extension spray device for remotely supporting and operating a conventional aerosol can having a crimped-cap closure with a moveable tubular control valve stem extending centrally out from said closure the improvement which comprises: can holding means having gripper means to fasten the spray device to said aerosol can by gripping the periphery of the crimped-cap closure, a spray member having a spray nozzle extending laterally of said can holding means, a coupling portion to engage said valve stem and a bore connecting said coupling portion to said spray nozzle for fluid from said valve stem to said spray nozzle, an extension tube connected at one end to said can holding means, a handle on the other end of said extension tube, a ball to force said spray member coupling portion against said valve stem to release fluid from the aerosol can and a line carried within said extension tube to move said ball by force applied at said handle, a longitudinal groove in said spray member opposed to said coupling portion, a surface opposed to said groove defining a wedgeshaped space between said surface and groove said ball being carried in said space, said ball being fastened to said line, and spring means biasing said ball toward the widest portion of said space.
