Abstract
Abstract A brick laying device comprises a rectangular frame which fits on a course of bricks. The central aperture in the frame defines a trough for a mortar layer to be laid on top of the bricks. At least one longitudinally extending member of the frame has a right angle section, of which one arm extends inwardly over the top of the bricks, and the other extends downwardly on the outside of the bricks to locate the frame on the bricks and to check the linearity of the course.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
213 words
A device for use in laying bricks, which comprises a frame adapted to be placed on a previously laid course of bricks to define a trough of even depth overlying said course wherein a layer of mortar may be laid ready to receive the next brick or bricks to be laid, the frame having two longitudinally extending side members spaced apart and parallel to one another and a pair of parallel spaced apart end members connecting the ends of said side members; at least one of the longitudinal members comprising a horizontally positioned element which rests on the horizontal surface of the said course and a vertically positioned element which rigidly depends from and along the outer edge of said horizontal element and is in contact with the vertical face of said course to insure linear alignment of said course; said horizontal element extending inwardly over said course of bricks to define the whole of one edge of the trough, the inward extension being preselected to provide a required recess for pointing and said horizontal element having a thickness chosen to provide the required depth of mortar to be applied; said spaced end members lying totally above the plane of the underside of said horizontal element when laid over a course of bricks.
Claim 2
Independent Claim
213 words
A device for use in laying bricks, which comprises a frame adapted to be placed on a previously laid course of bricks to define a trough of even depth overlying said course wherein a layer of mortar may be laid ready to receive the next brick or bricks to be laid, the frame having two longitudinally extending side members spaced apart and parallel to one another and a pair of parallel spaced apart end members connecting the ends of said side members; at least one of the longitudinal members comprising a horizontally positioned element which rests on the horizontal surface of the said course and a vertically positioned element which rigidly depends from and along the outer edge of said horizontal element and is in contact with the vertical face of said course to insure linear alignment of said course; said horizontal element extending inwardly over said course of bricks to define the whole of one edge of the trough, the inward extension being preselected to provide a required recess for pointing and said horizontal element having a thickness chosen to provide the required depth of mortar to be applied; said spaced end members lying totally above the plane of the underside of said horizontal element when laid over a course of bricks.
Claim 3
Dependent Claim
22 words
A device as claimed in claim 1, wherein both longitudinally extending members comprise said horizontally positioned element and said vertically positioned element.
Claim 4
Dependent Claim
57 words
A device as claimed in claim 1, wherein said horizontally positioned element comprises a hollow member having at least one vertical surface and at least one horizontal surface and said depending vertical element is integral with said hollow member and spaced from an inner vertical surface of said member a preselected distance to provide said required recess.
Claim 5
Dependent Claim
41 words
A device as claimed in claim 3, wherein both said longitudinally extending members comprise said hollow members, and said end members comprise U-shaped end members, the arms of the U-shaped end members being secured inside the ends of the hollow members.
Claim 6
Dependent Claim
39 words
A device as claimed in claim 1, wherein the vertical element of the longitudinal member extending outside and along said course of bricks is cut away at its end of a distance equal to the width of one brick.
Claim 7
Dependent Claim
74 words
A device as claimed in claim 1 for use with a course of bricks at a corner of a wall comprising two of said at least one side member secured together at right angles to define the outside of said course, two of said other longitudinally extending members spaced apart from and parallel to the respective first-mentioned members, and said end members connecting the respective parallel members at their ends remote from the corner.
Claim 8
Dependent Claim
16 words
A device as claimed in claim 6, comprising a strengthening member connected between said connecting means.
Claim 9
Dependent Claim
71 words
A device as claimed in claim 1 for use with a course of bricks forming a rectangular pillar, comprising four of said at least one side member secured together to form a rectangle, the said vertical element of each member extending outside and along said course of bricks, and said horizontal element extending inwardly over said course of bricks to define one whole edge of the trough and said required recess.
Claim 10
Dependent Claim
26 words
A device as claimed in claim 1, wherein said spaced end members are of adjustable length as required by the width of the course of bricks.
