Abstract
Abstract A method of building in which a number of bricks are laid simultaneously in a single course on a previously laid layer of mortar. The bricks may be vibrated to bed them down onto the motor. A machine having a clamp head adapted to receive a number of bricks in series and to clamp them. The clamp head has a pair of intersecting alignment faces against which the bricks are aligned before being clamped. The clamp head is displaceable from a loading position to an unloading or brick laying position. The clamp head also has a vibrator for bedding the bricks onto a layer of mortar by vibration.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
81 words
A machine for laying building elements, which includes a clamp head having a pair of intersecting alignment faces and clamp means adapted to clamp a plurality of building elements in series relationship against the alignment faces; clamp head positioning means for positioning the clamp head to align one of the alignment faces with the side of a wall to be built; and release means to release the grip of the clamp means when the building elements are in proper aligned position.
Claim 2
Dependent Claim
81 words
A machine for laying building elements, which includes a clamp head having a pair of intersecting alignment faces and clamp means adapted to clamp a plurality of building elements in series relationship against the alignment faces; clamp head positioning means for positioning the clamp head to align one of the alignment faces with the side of a wall to be built; and release means to release the grip of the clamp means when the building elements are in proper aligned position.
Claim 3
Dependent Claim
24 words
A machine as claimed in claim 1, in which the clamp head is resiliently mounted and in which it is provided with vibrator means.
Claim 4
Dependent Claim
89 words
A machine as claimed in claim 1, in which the alignment faces of the clamp head are substantially at right angles to each other; and in which the clamp head has a loading position in which one alignment face is substantially horizontal and the other alignment face projects upwardly above it along an edge remote from the wall to be built, and a laying position in which the face which is substantially horizontal in the loading position, is in alignment with the side of the wall to be built.
Claim 5
Dependent Claim
35 words
A machine as claimed in claim 3, which includes a cradle, the clamp head being mounted on the cradle; and in which the clamp head positioning means includes actuating means for displacing the clamp head.
Claim 6
Dependent Claim
57 words
A machine as claimed in claim 4, which includes a carrier, the cradle being mounted on the carrier and being displaceable relative thereto in a direction parallel to the alignment faces of the clamp head, and in which there is provided side shift displacing means for displacing the cradle relative to the carrier in the said direction.
Claim 7
Dependent Claim
61 words
A machine as claimed in claim 5, which includes a carriage, the carrier being mounted on the carriage and being displaceable relative thereto in a horizontal direction transversely to the line of intersection of the alignment faces, and in which the clamp head positioning means includes carrier displacing means for displacing the carrier relative to the carriage in the said direction.
Claim 8
Dependent Claim
47 words
A machine as claimed in claim 6, in which there is provided a column, the carriage being displaceable along the column in steps corresponding to the height between courses of building elements, and in which carriage displacing means are provided for displacing the carriage along the column.
Claim 9
Dependent Claim
31 words
A machine as claimed in claim 7, in which there is provided a trolley adapted to run along a guide track, and in which the column is mounted on the trolley.
