Abstract
Abstract A unique triangular point for use by a glazier has a star shaped central opening such that a plurality of such points can be stacked in oriented relationship to one another, and can be retained by a cotter key having skewed legs such that the key is easily inserted in opposed notches of the aligned openings in the points, and such that the key can be twisted for removal when inserting the stack of points in a conventional point driver. A plastic retainer is also disclosed and is adapted to fit into the aligned openings of the stacked points.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
32 words
A glazier's point for use in wood to retain a glass pane in place for glazing, said point comprising a flat metal plate of multi-sided planform and defining an opening extending therethrough.
Claim 2
Dependent Claim
32 words
A glazier's point for use in wood to retain a glass pane in place for glazing, said point comprising a flat metal plate of multi-sided planform and defining an opening extending therethrough.
Claim 3
Dependent Claim
47 words
The glazier's point as defined in claim 1 wherein said multi-sided flat metal point is of polygon planform, and wherein said opening is of non-circular configuration and has a maximum lateral dimension oriented along at least one bisector of at least one vertex of the polygon planform.
Claim 4
Dependent Claim
33 words
The glazier's point as defined in claim 2 wherein said polygon has at least three sides, and wherein said maximum dimension of said opening more particularly comprises opposed notches located on said bisector.
Claim 5
Dependent Claim
136 words
In combination with a stack of glazier's points each said point in the stack being as defined in claim 3, the improvement comprising fastener means for retaining the said stack of points in assembled relationship, said fastener means including an elongated shank portion extending through the non-circular openings of said points in said stack and including a head so configured as to abut the endmost point in said stack, and said fastener means further including releasable point engaging means at the end of said shank portion opposite said head to retain the stack axially, said fastener shank portion having at least one key defining rib extending axially thereof and cooperating with said opposed notches of said non-circular openings of said individual points to restrain the points from rotating with respect to one another in said stack.
Claim 6
Dependent Claim
66 words
The combination defined by claim 4 wherein all points in said stack are identical to one another, each such point having its non-circular opening defining several pairs of opposed notches, said pairs of opposed notches corresponding in number to the vertices of the polygonal point planform, each said pair of opposed notches oriented on a bisector of one of the vertices of said polygonal point planform.
Claim 7
Dependent Claim
62 words
The combination defined by claim 5 wherein each of said vertex bisectors defines a line of symmetry for each point in said stack, and wherein all of said notches in all of said points are aligned with one another in the assembled stack to receive the key defining shank portion of said fastener means in any one of a plurality of orientations.
Claim 8
Dependent Claim
42 words
The combination defined by claim 6 wherein said shank portion of said fastener means comprises a molded plastic portion defining a plurality of key defining ribs, said ribs slidably fitting in at least some of said notches in said aligned point openings.
Claim 9
Dependent Claim
52 words
The combination defined by claim 7 wherein said fastener means head is integrally formed with said shank, and wherein said releasable point engaging means comprises at least one of said ribs being upset adjacent the last point in the stack to provide resistance to axial disassembly of said fastener from said stack.
Claim 10
Dependent Claim
25 words
The combination defined by claim 8 wherein the numbers of key defining ribs corresponds to the number of notches in the openings of said points.
Claim 11
Dependent Claim
34 words
The combination defined by claim 9 wherein said fastener means head has the same cross sectional shape as that of said shank portion, said head formed by a laterally offset portion of said shank.
Claim 12
Dependent Claim
49 words
The combination defined by claim 6 wherein said fastener means comprises a one piece metal member bent to a generally U-shape and having said shank portion defined by the legs of the U, said legs having opposed marginal edges which define at least two of said key defining ribs.
Claim 13
Dependent Claim
123 words
The combination defined by claim 11 wherein said legs are skewed slightly relative to one another, and said means at the end of said shank portion opposite the head of said fastener means more particularly comprising laterally outwardly projecting tabs adjacent the ends of each of said skewed legs stack axially, and said skewed legs having tapered tips or ends to allow said shank portion to enter said non-circular opening upon assembly with said stack by causing said skewed legs to move into closer alignment with one another with the result that said legs tend to resiliently return to said skewed configuration and to cause said tabs to move outwardly of the last point in the stack to releasably engage it as aforesaid.
Claim 14
Dependent Claim
57 words
The combination defined by claim 12 wherein said legs are so configured upon assembly with said stack of points that said head can be twisted about the axis defined by said aligned point openings to overcome the resilient return (restoring) force which tends to skew said legs to facilitate disassembly in a point driver or the like.
Claim 15
Dependent Claim
42 words
The combination defined by claim 4 wherein said shank portion of said fastener means comprises a molded plastic portion defining a plurality of key defining ribs, said ribs slidably fitting in at least some of said notches in said aligned point openings.
Claim 16
Dependent Claim
49 words
The combination defined by claim 4 wherein said fastener means comprises a one piece metal member bent to a generally U-shape and having said shank portion defined by the legs of the U, said legs having opposed marginal edges which define at least two of said key defining ribs.
