Abstract
Abstract A pattern for use in forming molds for the casting of a family of products. Each of the products has a central portion of fixed dimensions and a pair of satellite portions of fixed dimensions spaced from the central portion. The distances between the central portion and the satellite portions and thus the structure therebetween are variable within the family of products. The casting pattern comprises a main body corresponding to the central portion and a pair of secondary portions corresponding to the satellite portions with each of the secondary portions having an elongate projection extending therefrom. The main body has openings formed therein on opposite sides thereof and each projection is telescopically received in one of the openings and slidable therein for adjustment of the distance between the main body and each of the secondary positions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
88 words
A pattern for use in forming casting molds of different dimensions, said pattern having a central portion and a pair of satellite portions spaced from and on opposite sides of the central portion, an elongate projection extending from each of said satellite portions, and bore means opening from opposite sides of said central portion, said elongate projections being telescopically received within said bore means and slidable therein to adjust the distance between said central portion and each of said satellite portions and the overall length of said pattern.
Claim 2
Dependent Claim
88 words
A pattern for use in forming casting molds of different dimensions, said pattern having a central portion and a pair of satellite portions spaced from and on opposite sides of the central portion, an elongate projection extending from each of said satellite portions, and bore means opening from opposite sides of said central portion, said elongate projections being telescopically received within said bore means and slidable therein to adjust the distance between said central portion and each of said satellite portions and the overall length of said pattern.
Claim 3
Dependent Claim
137 words
A pattern for use in forming molds for the casting of a family of products, said products having a generally elongate form with a central portion of fixed dimensions and a pair of satellite portions of fixed dimensions spaced from said central portion, the distances between said central portion and said satellite portions being variable within said family of products, said pattern comprising a main body corresponding to said central portion, a pair of secondary portions corresponding to said satellite portions, each of said secondary portions having an elongate projection extending therefrom, said main body having openings formed therein on opposite sides thereof each projection being telescopically received in one of said openings and slidable therein to adjust the distance between said main body and each of said secondary portions and the overall length of said pattern.
Claim 4
Dependent Claim
137 words
A pattern for use in forming molds for the casting of a family of products, said products having a generally elongate form with a central portion of fixed dimensions and a pair of satellite portions of fixed dimensions spaced from said central portion, the distances between said central portion and said satellite portions being variable within said family of products, said pattern comprising a main body corresponding to said central portion, a pair of secondary portions corresponding to said satellite portions, each of said secondary portions having an elongate projection extending therefrom, said main body having openings formed therein on opposite sides thereof each projection being telescopically received in one of said openings and slidable therein to adjust the distance between said main body and each of said secondary portions and the overall length of said pattern.
Claim 5
Dependent Claim
145 words
A pattern for use in forming casting molds of different dimensions, said pattern having a central portion and a pair of intermediate portions spaced from and on opposite sides of said central portion, each of said intermediate portions having an elongate projection extending therefrom, said central portion having openings formed therein on opposite sides thereof, said intermediate portion projections each being telescopically received in one of said openings and slidable therein to adjust the distance between said central portion and said intermediate portions, each of said intermediate portions having an opening formed therein on its side opposite said intermediate portion projections, a pair of end portions each having an elongate projecting extending therefrom, said end portion projections each being telescopically received in one of said openings in said intermediate portions and slidable therein to adjust the distances between said intermediate portions and said end portions.
Claim 6
Dependent Claim
145 words
A pattern for use in forming casting molds of different dimensions, said pattern having a central portion and a pair of intermediate portions spaced from and on opposite sides of said central portion, each of said intermediate portions having an elongate projection extending therefrom, said central portion having openings formed therein on opposite sides thereof, said intermediate portion projections each being telescopically received in one of said openings and slidable therein to adjust the distance between said central portion and said intermediate portions, each of said intermediate portions having an opening formed therein on its side opposite said intermediate portion projections, a pair of end portions each having an elongate projecting extending therefrom, said end portion projections each being telescopically received in one of said openings in said intermediate portions and slidable therein to adjust the distances between said intermediate portions and said end portions.
