Abstract
Abstract A centering clip for window frames, comprising an element of spring metal to provide a resilient clip, having a base portion attached to the top edge of a window frame, and inclined portion integrally formed with the base portion at an acute angle, with the inclined portion having a row of teeth along the free end. When the window frame is inserted into the mounting opening or mounting frame, the inclined portion of the resilient clip engages the top edge of the mounting frame and is compressed when the window frame is inserted. The row of teeth at the free end of the centering clip bites into the top edge of the mounting frame and holds the window frame against removal until the centering clip is depressed to disengage the teeth from the top edge of the mounting frame. The window frame is thus held within the mounting frame until a workman is able to nail the window frame in place. The resilience of the centering clip allows the workman to move the window frame within the mounting frame both laterally and longitudinally small distances in order to properly center. A pair of such centering clips is preferably used, both attached to the same edge of the window frame.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
284 words
The method of installing a window frame in a mounting aperture, comprising the steps of selecting a window frame of appropriate size for mounting in said mounting aperture with room for moving said window frame small distances upwardly and downwardly as well as from side to side when initially inserted into said mounting aperture to center said window frame within said mounting aperture, selecting at least one spring clip having a base for anchoring to an end wall of said window frame and having a resilient member extending diagonally from said base whose free end includes engagement means spaced apart from said base a distance at least equal to the dimension by which said mounting aperture is greater than said window frame in said upward and downward direction, anchoring said base of said clip to one of the top and bottom walls of said window frame with the said free end of said resilient member slanting diagonally outwardly and away from the direction in which said window frame is to be inserted into said mounting aperture, inserting said window frame into said aperture, causing said free end of said resilient member of said spring clip to engage the corresponding facing portion of said mounting aperture with the opposite end wall of said window frame abutting against the corresponding portion of said mounting aperture which faces said opposite end wall of said window frame, letting go of said window frame to obtain tools and equipment for permanently securing said window frame in a mounting aperture allowing said spring clip in engagement with a portion of said mounting aperture to temporarily retain said window frame therein, and permanently connecting said window frame in said mounting aperture.

Claim 3
Dependent Claim
67 words
The method of installing a window frame in a mounting aperture as set forth in claim 1, including the additional step of adjusting said window frame in one of the directions upwardly, downwardly and sideways against the bias of said spring clip in engagement with a portion of said mounting aperture to center said window frame in a desired position before permanently securing within said mounting aperture.
Claim 4
Dependent Claim
54 words
The method of installing a window frame in a mounting aperture as set forth in claim 1, including the additional step of selecting an additional one of said spring clips and anchoring to said one of said top and bottom end walls of said window frame to which said other spring clip is anchored.
