Abstract
Abstract A support brace for freshly constructed brick walls and the like is provided, and a method for installing and using the same is described. Should the brace foot plate tend to sink into the underlying ground or to slip away from the wall, the attached buttress brace automatically extends to accommodate this movement. Wind or other forces tending to topple the wall are resisted by the stiff buttress brace and associated brace elements. The buttress brace can be extended or retracted over relatively large distances by gross adjustment means including a ratchet and rack mechanism. The buttress brace can be extended or retracted over short distances with great precision by a fine adjustment means including a turnbuckle mechanism.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
234 words
An adjustable support brace for walls and the like, comprising foot anchor means for providing a foundation for the brace on an underlying surface, wall anchor means for attaching the brace to the supported wall including an anchor member adapted to extend through the wall and at least one face plate member for attachment to the anchor member in a position closely adjacent the wall face, thereby securing the anchor member in its position, the support brace further comprising stiff arm means attachable to the wall anchor means, stiff arm adjustment means for adjusting the length of the stiff arm means, first, second and third axially aligned struts comprising buttress brace means attachable to the stiff arm means, to the wall anchor means, and to the foot plate means, said first and second struts being telescopically interconnected, and buttress brace adjustment means for adjusting the length of the buttess brace means to place the buttress brace means in wall-supporting compression when the buttress brace means is attached to the stiff arm means, to the wall anchor means, and to the foot plate means, the buttress brace adjustment means including gross adjustment means rigidly positioning the first and second telescopically interconnected struts in any one of a finite plurality of axially spaced apart positions, and fine adjustment means positioning the second and third struts in any one of an infinite plurality of axially ranged positions.
Claim 2
Dependent Claim
234 words
An adjustable support brace for walls and the like, comprising foot anchor means for providing a foundation for the brace on an underlying surface, wall anchor means for attaching the brace to the supported wall including an anchor member adapted to extend through the wall and at least one face plate member for attachment to the anchor member in a position closely adjacent the wall face, thereby securing the anchor member in its position, the support brace further comprising stiff arm means attachable to the wall anchor means, stiff arm adjustment means for adjusting the length of the stiff arm means, first, second and third axially aligned struts comprising buttress brace means attachable to the stiff arm means, to the wall anchor means, and to the foot plate means, said first and second struts being telescopically interconnected, and buttress brace adjustment means for adjusting the length of the buttess brace means to place the buttress brace means in wall-supporting compression when the buttress brace means is attached to the stiff arm means, to the wall anchor means, and to the foot plate means, the buttress brace adjustment means including gross adjustment means rigidly positioning the first and second telescopically interconnected struts in any one of a finite plurality of axially spaced apart positions, and fine adjustment means positioning the second and third struts in any one of an infinite plurality of axially ranged positions.
Claim 3
Dependent Claim
55 words
An adjustable wall support brace according to claim 1 wherein said gross buttress brace adjustment means includes pin means adapted to engage aligned holes formed in said first and second struts to rigidly interposition them, the pin means protruding from both struts to permit the pin to be manually grasped and withdrawn from the struts.
Claim 4
Dependent Claim
191 words
An adjustable wall support brace according to claim 1 wherein at least a portion of said second strut is telescopically received inside a portion of said first strut, and wherein said gross buttress brace adjustment means includes extension means for automatically extending the length of the buttress brace means in response to relative movement of the wall anchor means and the foot plate means, and alternatively manually extending and retracting the length of the buttress brace means when desired, said extension means including a ratchet member fixed to the first strut and a rack-engaging ratchet member fixed to the second strut leg, the first strut ratchet member being positioned to release and reengage the second strut rack member in succesSive relatively more extended positions when tensioning extending forces are applied to the first and second struts of the buttress brace, and the first strut ratchet member being located at least partly outside both said first and second strut members to permit the ratchet member to be grasped and withdrawn from engagement with the rack member when gross adjustment of the relative positions of the first and second strut members is desired.
Claim 5
Dependent Claim
78 words
An adjustable wall support brace according to claim 1 wherein said fine buttress brace adjustment means includes a bi-ended turnbuckle member provided with opposite-handed threads at each end, and wherein said second and third strut members are provided with opposite-handed mating threads, the turnbuckle member, when threaded upon the struts, permitting the struts to be axially drawn toward each other or axially forces apart by appropriate rotation of the turnbuckle member relative to the second and third struts.
Claim 6
Dependent Claim
40 words
An adjustable wall support brace means according to claim 1 wherein said anchor means includes a slotted anchor member, and two wall face plates slotted for mutual engagement with the anchor member slots in positions closely adjacent the wall faces.
Claim 7
Dependent Claim
75 words
An adjustable support brace according to claim 1 including slip collar means connecting said stiff arm means and said buttress brace means, said slip collar means including a rigid collar member having arm internal surface congruent with the right cross-section silhouette shape of the buttress brace means at the point at which the collar member is attached to the buttress brace means, and pin means journalling the stiff arm means on the buttress brace means.
