Building material applicator

An applicator for introducing and spreading building material in a controlled manner to a building surface comprising;

• a housing adapted to contain a predetermined amount of building material therein, guide means on the housing adapted to engage with the building surface and direct the applicator into desired alignment therewith and along a desired path when the applicator is associated with the building surface and moved therealong, metering means in communication with the interior of the housing and with at least one opening to the exterior thereof to direct a predetermined pattern of building material from the interior of the housing through the opening and onto the building surface, the housing including a base and an arrangement of side walls extending from the base and forming therewith an enclosure for a chamber to hold building material, the base adapted for engagement with the building surface, the side walls having a configuration when forming the chamber so that building material is directed toward a pair of spaced openings in the base communicating with the building surface when the applicator is positioned thereon, the metering means including a beater on the housing and positioned in the travel path of the building material from the chamber through the openings in the housing, the beater adapted to be actuated when the applicator is moved along the building surface to facilitate metering and direction of building material from the chamber through the openings onto the beater surface, the beater including an axle mounted on the housing perpendicular to the direction of travel of the applicator, the axle being bent at predetermined points along its length into a configuration forming at least one paddle within the housing positioned so that rotation of the axle will cause the paddles to rotate and engage and direct building material through the openings onto the building surface, beater drive means on the housing connected to the axle and having a portion thereon in engagement with the building surface so that movement of the applicator along the the building surface will actuate the beater drive means to rotate the axle, and the beater drive means includes a first gear mounted on the axle and positioned on the exterior of the housing, a second gear meshed with the first gear and positioned on the housing, a third gear on the housing and meshed with the second gear, the third gear mounted on a vertical shaft extending downward from the exterior of the housing into an alignment with a guide surface associated with the building surface, a beater roller on the shaft in position for engagement with the guide surface when the applicator is moved along the building surface so as to rotate the shaft, the gears, and the axle and paddles.

• a housing adapted to contain a predetermined amount of building material therein, guide means on the housing adapted to engage with the building surface and direct the applicator into desired alignment therewith and along a desired path when the applicator is associated with the building surface and moved there along, and metering means in communication with the interior of the housing and with at least one opening to the exterior thereof to direct a predetermined pattern of building material from the interior of the housing through the opening and onto the building surface the housing including a base and an arrangement of side walls extending from the base and forming therewith an enclosure for a chamber to hold building material, the base adapted for engagement with the building surface, the side walls having a configuration when forming the chamber so that building material is directed toward a pair of spaced openings in the base communicating with the building surface when the applicator is positioned thereon, the metering means including a beater on the housing and positioned in the travel path of the building material from the chamber through the openings in the housing, and the beater adapted to be actuated when the applicator is moved along the building surface to facilitate metering and direction of building material from the chamber through the openings onto the beater surface, the beater including an axle mounted on the housing, at least one paddle on the axle and positioned in the housing so that rotation of the axle will cause the paddle to rotate and engage and direct building material through the openings onto the building surface, beater drive means on the axle and extending from the housing into direct engagement with the building surface so that movement of the applicator along the building surface will automatically actuate the beater drive means to rotate the axle and paddle, the axle is mounted on the housing perpendicular to the direction of travel of the applicator, the axle being bent at predetermined points along its length into a configuration to form the at least one paddle, the beater drive means including a wheel on the axle, the wheel extending beyond the base into engagement with the building surface when the applicator is positioned thereon, a pair of paddles on the axle between the ends thereof and having the wheel located therebetween whereby rotation of the wheel in contact with the building surface when the applicator is moved therealong will automatically cause the paddles to rotate and engage and direct building material through the openings onto the building surface.
