Abstract
Abstract Apparatus and a method for securing capillary tubes and other small diameter components within a refrigeration machine. A capillary plug button having a retainer plate in which various small diameter components may be secured has extending therefrom a pair of fastening legs. The fastening legs are inserted through an opening within an internal wall of the refrigeration machine such that projections on the legs contact one side of the wall and the retainer plate contacts the opposite side of the wall thereby securing the plug button within the opening and securing the small diameter components within the retainer plate. The retainer plate has a slot connecting the edge of the plate to a plurality of apertures thereby allowing the plug button to be spread apart such that the components may be inserted into the apertures of the retainer plate.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
217 words
A method of securing at least one small diameter component in an opening extending through a wall of a refrigeration machine which comprises the steps of: securing the component in a retainer plate having apertures for the receipt of the component, said step of securing including forming a slot in the retainer plate, said slot joining the apertures of the retainer plate to an exterior edge of the retainer plate; spreading the retainer plate such that the component may be slid into the slot therein; sliding the component into the slot to an aperture where the component may be secured; and releasing the retainer plate so that the component is secured within the aperture connected to the slot; and affixing the retainer plate to the wall, said retainer plate having a body attached thereto and at least one fastening leg formed from the body but movable separate therefrom and wherein the step of affixing further includes compressing the fastening leg; and inserting the compressed fastening leg through the opening in the wall such that the fastening leg resumes its original position contacting the wall on one side and the retainer plate contacting the wall on the other side such that the retainer plate is secured to the wall and the component are secured within the retainer plate.
Claim 2
Independent Claim

A method of securing at least one small diameter component in an opening extending through a wall of a refrigeration machine which comprises the steps of: securing the component in a retainer plate having apertures for the receipt of the component, said step of securing including forming a slot in the retainer plate, said slot joining the apertures of the retainer plate to an exterior edge of the retainer plate; spreading the retainer plate such that the component may be slid into the slot therein; sliding the component into the slot to an aperture where the component may be secured; and releasing the retainer plate so that the component is secured within the aperture connected to the slot; and affixing the retainer plate to the wall, said retainer plate having a body attached thereto and at least one fastening leg formed from the body but movable separate therefrom and wherein the step of affixing further includes compressing the fastening leg; and inserting the compressed fastening leg through the opening in the wall such that the fastening leg resumes its original position contacting the wall on one side and the retainer plate contacting the wall on the other side such that the retainer plate is secured to the wall and the component are secured within the retainer plate.
Claim 3
Dependent Claim
100 words
The method as set forth in claim 1 wherein the body affixed to the retainer plate is generally cylindrical in configuration, and further comprising the steps of: providing separation slots in the body to form fastening legs therebetween, said fastening legs being displacable relative to the body; and the step of forming a slot in the retainer plate including forming an extension of the same slot through the body such that during the step of spreading the retainer plate the body is also spread enabling a component to be inserted through both slots into an aperture in the retainer plate.
