Abstract
Abstract A spacer for bricks of a facing brickwork placed in front of an inner brickwork, whereby the spacer can be universally used and at the end of the bricklaying work can be removed from the mortar joints of the front of the wall, so that it does not constitute a disposable part and can be reused. Such a spacer includes a unitary body having two contact surfaces in a common plane and below the contact surfaces nominal width stops in two parallel planes perpendicular to the contact surfaces and nominal depth stops are located in two further parallel planes perpendicular both to the plane of the contact surfaces and to the planes of the nominal width stops for adjacent bricks, with the distance between the planes corresponding to the nominal depth of the distance between the facing brickwork and the inner brickwork. The nominal depth stops extending between two adjacent bricks of the facing brickwork on the one hand and the inner brickwork to be faced on the other.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
220 words
Spacer for laying bricks of a facing brickwork to be placed in front of and at a predetermined distance from a previously laid inner brickwork, said spacer comprising a unitary body having a normal use position for placing the facing brickwork in front of an upstanding inner brickwork and in the normal use position said spacer comprising a first horizontal wall including a pair of contact surfaces located in a common horizontal plane with said contact surfaces facing downwardly, a pair of vertically extending width stops each extending perpendicularly downwardly from the common plane of said contact surfaces, said width stops being in spaced relation so that the overall spacing between the surfaces of said stops facing away from one another corresponds to the normal horizontal joint width between two adjacent bricks in the same course, wall means defining at least a pair of distance stops disposed in spaced parallel relation and extending perpendicularly to said contact surfaces and to said width stops, said first wall and said width stops extending perpendicularly from one side of a common vertically extending plane and said wall means extending perpendicularly in the opposite direction from said common vertically extending plane and the spacing between said distance stops in the horizontal direction corresponding to the spacing between the facing brickwork and the inner brickwork.
Claim 2
Dependent Claim
220 words
Spacer for laying bricks of a facing brickwork to be placed in front of and at a predetermined distance from a previously laid inner brickwork, said spacer comprising a unitary body having a normal use position for placing the facing brickwork in front of an upstanding inner brickwork and in the normal use position said spacer comprising a first horizontal wall including a pair of contact surfaces located in a common horizontal plane with said contact surfaces facing downwardly, a pair of vertically extending width stops each extending perpendicularly downwardly from the common plane of said contact surfaces, said width stops being in spaced relation so that the overall spacing between the surfaces of said stops facing away from one another corresponds to the normal horizontal joint width between two adjacent bricks in the same course, wall means defining at least a pair of distance stops disposed in spaced parallel relation and extending perpendicularly to said contact surfaces and to said width stops, said first wall and said width stops extending perpendicularly from one side of a common vertically extending plane and said wall means extending perpendicularly in the opposite direction from said common vertically extending plane and the spacing between said distance stops in the horizontal direction corresponding to the spacing between the facing brickwork and the inner brickwork.
Claim 3
Dependent Claim
103 words
Spacer, as set forth in claim 1, wherein said spacer is in the form of a box-like hollow body comprising a plurality of second walls of approximately equal thickness, a pair of said second walls being disposed vertically extending and each forming a pair of said distance stops at the opposite vertically extending ends of said second walls, and said first wall located in a common plane with one of said second walls with said first wall projecting from one side of the common vertically extending plane and said second wall being located on the opposite side of said common vertically extending plane.
Claim 4
Dependent Claim
92 words
Spacer, as set forth in claim 2, wherein said first wall having a front edge disposed in parallel relation with and spaced horizontally from said common vertically extending plane, a third wall extending centrally downward from the front edge of said first wall and said third wall having a horizontal dimension corresponding to the dimension between the outwardly facing surfaces of said width stops, and said second walls forming distance stops extending vertically downwardly from a pair of opposite sides of said second wall located in the plane of said first wall.
Claim 5
Dependent Claim
22 words
Spacer, as set forth in claim 3, wherein a reinforcing wall extends perpendicularly to said first wall and to said third wall.
Claim 6
Dependent Claim
74 words
Spacer, as set forth in claim 3, wherein a T-shaped reinforcing wall includes a head portion and a leg portion, said head portion extending in said common vertically extending plane between a pair of said second walls and located along the junction between said first wall and said second wall located in the plane of said first wall, and said leg portion extending perpendicularly to said head portion and located below said first wall.
Claim 7
Dependent Claim
15 words
Spacer, as set forth in claim 1, wherein said spacer comprises a shaped plastic body.
Claim 8
Dependent Claim
45 words
Spacer, as set forth in claim 1, wherein a projection extends vertically upwardly from said front wall above said width stops and the vertical dimension of said projection above said first wall corresponding to the nominal height of the horizontal joints in the facing brickwork.
Claim 9
Dependent Claim
14 words
Spacer, as set forth in claim 1, wherein said spacer comprises a metal stamping.
Claim 10
Dependent Claim
140 words
Spacer, as set forth in claim 1, wherein a pair of fourth walls extend upwardly from said first wall with each said fourth wall extending from an opposite edge of said first wall extending outwardly perpendicularly relative to said common vertically extending plane, said fourth walls having a height substantially corresponding to the height of the horizontal joints of the facing brickwork and said wall means comprising second walls extending in the opposite direction from said vertically extending common plane relative to the direction of said first wall, one of said second walls extending in the common plane with said first wall and having a pair of said second walls extending downwardly from the opposite sides thereof with the height of said downwardly extending second walls being substantially equal to the height of the horizontal joint of the facing brickwork.
Claim 11
Dependent Claim
28 words
Spacer, as set forth in claim 9, wherein said second wall located in the same plane as said first wall having an opening therethrough constructed as an eyelet.
