Abstract

Abstract An attachment for applicators used to apply liquid adhesive to a seam between adjacent edges of floor covering. The attachment comprises a support plate having a generally rectangular main body portion, an integral collar extending upwardly from the top edge thereof, and a pair or cylindrical rollers each rotatably mounted between pairs of projections which extend downwardly from the bottom of the main body portion. The collar of the attachment is adapted to be adjustably mounted on the cylindrical nozzle of a seam sealer dispensing head and held in place thereon by appropriate fastening means. In use, the attachment provides sidewise stabilization for the applicator and a means for setting and maintaining the desired angle thereof relative to the surface of the floor covering as it is moved along the seam therein.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 321 words
In a device for applying liquid adhesive to a seam between adjacent edges of floor covering comprising a container for liquids, a nozzle, and means for fastening said nozzle to said container, said nozzle having an elongated body portion with a centrally located passageway extending completely through the length thereof, the end of the body opposite from the fastening means being tapered and having an opening at the extreme end thereof interconnected with the passageway through the elongated body portion of the nozzle and, a parting fin located closely adjacent to and below said opening and extending downwardly from the tapered end of said nozzle at right angles to the longitudinal axis thereof, the improvement comprising a support plate having a one-piece generally rectangular main body portion with flat front and rear surfaces, an integral collar extending upwardly from the top edge thereof, means for adjustably and removably securing said collar on the elongated body portion of said nozzle so that the main body portion of said support plate extends downwardly below said nozzle in a plane perpendicular to the longitudinal axis thereof, mounting means comprising integral pairs of longitudinally spaced projections on each side of the bottom edge of the main body portion of the support plate, and a pair of cylindrical rollers one of which is mounted between each pair of projections, said rollers being rotatably positioned on the mounting means and being so mounted and each having a diameter sufficient to cause the outer surface thereof to extend outwardly beyond the thickness and the lower edge of the projections whereby, in use, the rollers and the tapered end of the nozzle provide a three-point contact means for stabilizing, supporting, and maintaining the seam sealing device at a predetermined desired angle to the surface of the floor covering with the opening in the extreme end of the nozzle positioned in the desired relationship to the seam to be sealed.
