Description

BRICK LAYING TOOLS

This invention relates generally to brick laying tools and more particularly relates to a brick laying tool or tools which will enable an inexperienced user to lay bricks course upon course, to a professional standard of appearance and structural requirements.

In usual brick laying practice, the mortar is manually spread on the top of the existing course with a trowel. .A hand-held brick is buttered on the end and placed on the top of a line of just-thrown mortar. The brick is then aligned by bumping the brick down into the mortar. The mortar is then cleaned off, and the joints finished off as required. This method suffers from the disadvantage that mortar is handled twice, once from the barrow o; the mortar board - and once from the mortar board to the hand-deposited mortar line. The physical effort of holding the loaded mortar board with one hand and depositing of mortar with the other is considerable. Extrusion of mortar causes hi h loss and recycling of mortar and tends to dirty the bricks. Mortar has to be buttered o each brick end before laying. This situat.ion demands that the bricks are in close proximity to mortar storage for application of mortar and mortared bricks are then carried to the mortar line for laying.

It is an ob ect of t.hi.s invention to provide a brick wall, mortar course tool.

'Another object of this invention is to provide a brick wall mortar perpend tool .

According to the invention, there is provided a tool for carrying mortar and laying mortar joints upon a brick wall course, the tool comprising a body with a tray portion having the bottom thereof formed into an opening fo dispensing mortar therefrom, the lateral dimensions of the opening corresponding substan ially to the dimensions of mortar laid upon a brick in a brick wall course, a slide plate bottom of the tray to open and close the tray opening being connected to, or integrally formed with at least one slide sleeve, the tray portion being connected to, or integrally formed with at least one runner for the at least one side sleeve, whereby inward and outward relative sliding movement of the sleeve and runner closes and opens the tray mortar dispensing opening. Preferably, the slide plate bottom of the tray of the tool has a pair of integrally moulded sleeves there¬ on and the tray frame is integrally moulded with a pair of runners upon which the sleeves are adapted to be slidably reciprocated, the sleeves are interconnected by a handle extending therebetween, the runners are connected by a handle extending between outwardly directed end^'s .thereof and the handles are adapted to be moved towards' and away from each other to open and close the mortar dispensing opening. According to another aspect, the invention resides in a brick wall, mortar perpend tool comprising an open-top hopper adapted to receive and carry mortar and which has a transverse bottom slot adapted to tte "placed over a mortar perpend gap on a brick wall after horizontal brick course has been laid, the mortar being adapted to be rammed into the perpend gap via the slot, while the hopper is in place on a brick wall course.

Preferably, a perpend mortar retaining leg depends downwardly from each bottom corner of the hopper, adjacent each end of the^' slot, the legs being adapted to retain mortar in the perpend gap between bricks, while mortar is being placed into the gap.

The invention, according to a still further aspect resides in a combination of both of the above tools as a kit to be used together.
