Abstract
Abstract A spray nozzle for aerosols and other spray devices adapted for spraying an antifreeze agent and/or a lubricant into a lock, hinge, or the like. The nozzle comprises a generally conical member having an axially extending passageway for the discharge of material, and the nozzle toward its discharge end has diametrically opposed wedge-shaped portions removed therefrom so as to provide a cross-sectional width in one direction which is significantly less than that in a cross-sectional plane at right angles to the first, thereby providing a discharge end which may be readily inserted into a lock or the like but which nevertheless has sufficient strength to resist deformation.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
173 words
A nozzle member for spraying a comminuted substance together with a gaseous carrier into a small aperture such as a lock: said member being of generally conical shape and having a passageway along its axis for the discharge of said substance and said carrier in a direction toward its narrowed end; said member having diametrically opposed portions removed from its conical outer surface from its discharge end to substantially halfway along its axial length; each said removed portion being defined by a first surface generally normal to the axis of said member and a second surface extending to said discharge end at an acute angle to said axis; said two first surfaces being generally coplanar and together forming a stop ledge to control the depth of entry of said discharge end into the aperture; and said member from the axial location of said first surfaces to said discharge end having a substantially smaller width in one cross-sectional plane through said axis than through a second cross-sectional plane at right angles to the first.
Claim 2
Dependent Claim
173 words
A nozzle member for spraying a comminuted substance together with a gaseous carrier into a small aperture such as a lock: said member being of generally conical shape and having a passageway along its axis for the discharge of said substance and said carrier in a direction toward its narrowed end; said member having diametrically opposed portions removed from its conical outer surface from its discharge end to substantially halfway along its axial length; each said removed portion being defined by a first surface generally normal to the axis of said member and a second surface extending to said discharge end at an acute angle to said axis; said two first surfaces being generally coplanar and together forming a stop ledge to control the depth of entry of said discharge end into the aperture; and said member from the axial location of said first surfaces to said discharge end having a substantially smaller width in one cross-sectional plane through said axis than through a second cross-sectional plane at right angles to the first.
Claim 3
Dependent Claim
27 words
The nozzle member of claim 1 which further includes an annular surrounding portion at the end remote from said discharge end and forming a second stop ledge.
Claim 4
Dependent Claim
153 words
A spray device nozzle for spraying a mist of a liquid and a gaseous carrier preferably for introducing lubricating agents and antifreeze agents into a motorcar lock, said nozzle having a straight, central and preferably cylindrical passage for the outflow of the liquid and the gaseous carrier, characterized in that the nozzle includes three portions, a first of said portions including the nozzle''s tip and having flat side surfaces which form a small angle with the nozzle''s main axis, a second of said portions being adjacent to said first portion and having a frustoconical shape, whereby a stop surface being perpendicular to said main axis is formed in the transition between said first and second portions, and a third of said portions being adjacent to said second portion and forming a flange, whereby a further surface being perpendicular to said main axis is formed in the transition between said second and third portions.
Claim 5
Dependent Claim
153 words
