Abstract

Abstract A nozzle for supplying filler material to a void formed between adjacent surfaces is described which comprises a cylindrical barrel having connecting means at one end and an applicator tip at the other end. A bore extends through the barrel and has a constant diameter portion near the tip end thereof. The tip end is formed by the geometric intersection of essentially four beveled surfaces, i.e. a pair of opposed angular cheeks controlling side-to-side movement, vertical depth of the nozzle aperture in the void, and formation of a seal in the void between adjacent contiguous surfaces; a leading surface permitting the nozzle to follow the line of application and also depressing any previously filled voids of this same material which intersect at an angle; and a trailing surface adapted to permit the tip to strike the exposed surface of the filler material clean as the nozzle progresses.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 126 words
A nozzle for the distribution of filler material, having a plastic consistency, comprising a. generally cylindrical barrel means, b. central bore means extending longitudinally throughout the extent of said barrel means and forming a supply opening and a tip opening, c. tip means surrounding said tip opening, said tip means being formed by the intersection of d. a pair of opposed beveled cheek surface means formed on said barrel means, e. a beveled trailing surface formed on said barrel means, and f. a beveled leading surface formed on said barrel means, said leading surface and trailing surface being opposed diametrically and generally equidistantly between said opposed cheek surface means, and wherein said bore means in the vicinity of said tip means has a substantially constant diameter.
Claim 2
Dependent Claim 126 words
A nozzle for the distribution of filler material, having a plastic consistency, comprising a. generally cylindrical barrel means, b. central bore means extending longitudinally throughout the extent of said barrel means and forming a supply opening and a tip opening, c. tip means surrounding said tip opening, said tip means being formed by the intersection of d. a pair of opposed beveled cheek surface means formed on said barrel means, e. a beveled trailing surface formed on said barrel means, and f. a beveled leading surface formed on said barrel means, said leading surface and trailing surface being opposed diametrically and generally equidistantly between said opposed cheek surface means, and wherein said bore means in the vicinity of said tip means has a substantially constant diameter.
Claim 3
Dependent Claim 29 words
The nozzle of claim 1 wherein said barrel means is provided with means for connecting a supply package of filler material thereto in the vicinity of said supply opening.
Claim 4
Dependent Claim 39 words
The nozzle of claim 1, wherein the trailing surface intersects said tip means along a line spaced from said tip opening a distance sufficient to permit said tip to strike a clean grout line, but insufficient to cause drag.
Claim 5
Dependent Claim 56 words
The nozzle of claim 1, wherein the angle of bevel of said leading surface is such that it permits sufficient mobility of the nozzle to allow it to follow the contours of the edges of a void whether irregular or straight, and to gently depress the filler material in previously filled voids intersecting at an angle.
