Abstract
Abstract An outer rectangular frame having intermediate members adjustable between opposite outer side members to provide a canvas engaging rectangular stretching frame of any desired size having four flush canvas enagaging frame members on which a needlepoint canvas of any size may be engaged and stretched for blocking the canvas to truly rectangular shape. Canvas engaging pins project from two side and one intermediate frame members; and staple pins are hinged to the other intermediate frame member and engage over the top of and through the canvas at one edge of the canvas. Crank arm screws are journaled in opposite side members and have screw thread engagement with the intermediate members to adjust the latter toward and away from the side members. The intermediate members normally are maintained parallel with the side members between which the intermediate members are movable. The staple mounting intermediate frame member has a series of removable blocks of varying lengths to provide staple zones variable by uniform increments on said staple mounting member.

Claim 1
Independent Claim
319 words
A needlepoint canvas blocking device including first and second pairs of spaced frame side members having coplanar top surfaces connected at corners to form an outer rectangular frame; a first intermediate blocking frame member located parallel with and extending in spaced relation between the side members of the first pair and having a top surface coplanar with the coplanar outer frame top surfaces; means journaled in the first pair frame side members and engaging the first intermediate member for adjusting said first intermediate member in parallel relation to and toward and away from one of the side members of said first pair; a set of spaced aligned pins projecting upward from the top surface of said one member of said first pair, a second set of spaced aligned pins projecting upward from the top surface of one member of the second pair extending from a corner connection with said one member of said first pair, and a third set of spaced aligned pins projecting upward from the top surface of said first intermediate frame member; a second intermediate blocking frame member located parallel with and extending in spaced relation between the side members of the second pair and beneath the first intermediate frame member; sectional blocks removably mounted on the second intermediate frame member between the one side member of the first pair and the first intermediate frame member having top surfaces co-planar with the coplanar outer frame top surfaces; staples hinged to the sectional blocks at spaced intervals having pointed ends movable to engaged position projecting from above into aligned grooves formed in said blocks parallel with the pins in the one member of the second pair; and means journaled in the second pair frame members and engaging the second intermediate member for adjusting the second intermediate member with sectional blocks thereon in parallel relation to and toward and away from said one member of the second pair.

A needlepoint canvas blocking device including first and second pairs of spaced frame side members having coplanar top surfaces connected at corners to form an outer rectangular frame; a first intermediate blocking frame member located parallel with and extending in spaced relation between the side members of the first pair and having a top surface coplanar with the coplanar outer frame top surfaces; means journaled in the first pair frame side members and engaging the first intermediate member for adjusting said first intermediate member in parallel relation to and toward and away from one of the side members of said first pair; a set of spaced aligned pins projecting upward from the top surface of said one member of said first pair, a second set of spaced aligned pins projecting upward from the top surface of one member of the second pair extending from a corner connection with said one member of said first pair, and a third set of spaced aligned pins projecting upward from the top surface of said first intermediate frame member; a second intermediate blocking frame member located parallel with and extending in spaced relation between the side members of the second pair and beneath the first intermediate frame member; sectional blocks removably mounted on the second intermediate frame member between the one side member of the first pair and the first intermediate frame member having top surfaces co-planar with the coplanar outer frame top surfaces; staples hinged to the sectional blocks at spaced intervals having pointed ends movable to engaged position projecting from above into aligned grooves formed in said blocks parallel with the pins in the one member of the second pair; and means journaled in the second pair frame members and engaging the second intermediate member for adjusting the second intermediate member with sectional blocks thereon in parallel relation to and toward and away from said one member of the second pair.
Claim 3
Dependent Claim
27 words
The device set forth in claim 1 in which spring latch means on the sectional blocks removably mount the sectional blocks on the second intermediate frame member.
Claim 4
Dependent Claim
42 words
The device set forth in claim 1 in which the sectional blocks each have hook-shaped formations thereon, in which a corner recess is formed in the second intermediate frame member, and in which said block hook-shaped formations engage with said corner recess.
Claim 5
Dependent Claim
59 words
The device set forth in claim 1 in which the adjusting means for adjusting the first and second intermediate members comprise screws journaled in the pairs of frame side members and engaging nuts carried by the first and secoNd intermediate members, and in which the screws each have a crank arm located outside of the outer frame side members.
Claim 6
Dependent Claim
61 words
The device set forth in claim 1 in which scales are provided along the top surfaces of the one side member of the first pair, along the side members of the second pair, and along the first intermediate member to determine parallelism between the intermediate members and their respective members with which each intermediate member is to be maintained in parallelism.
Claim 7
Dependent Claim
25 words
The device set forth in claim 1 in which the pins of each set of spaced aligned pins are spaced apart at 1/2 inch intervals.
Claim 8
Dependent Claim
47 words
The device set forth in claim 6 in which the sectional blocks have varying lengths predetermined to provide combinations of blocks to form total block lengths extending between the one side member of the first pair and the first intermediate frame member variable at 1/2 inch intervals.
Claim 9
Dependent Claim
20 words
The device set forth in claim 7 in which staples are hinged to the sectional blocks at 1/2 inch intervals.
