MEANS FOR AIPPLYING 1VIORTAR TO HOLLOW BRICKS.
Original application filed June 25, 1920,'Seria1'No. 391,738, and in Sweden August 2, 1918. Divided and this application filed June 30, 1921.
This invention relates to a method of applying mortar to hollow bricks in an. even and thin layer, divided from my copending U. S. patentapplication Serial No. 391,788.
The known method of applying the mortar, when erecting walls and fioorings from hollow bricks, consisting in dipping the bricks into the mortar has proved to be very unsatisfactory, because of the joints notbe ingentirely filled. in walls built up from hollow bricks by dipping thebricks into the mortar, the joints will not be tight owing to the mortar covering the joint surfaces only at intervals. The significance thereof with reference to the strength as well as to the insulation can easily be seen, and in case of floorings of the type described in my application Serial N umber 391,738 such a method is simply detrimental, since the w iole joint surface of the bricks is required to resist the great stresses exerted on the bricks. The difficulties in this case are very great since the joints, especially the vertical joints in iiooi'ings of said type, should be very thin in order to resist the enormous stresses aris- .ing on account of the tightening of the'rows of bricks and the immediate removal of the scaffolding *ithout allowing the flooring to settle even in the slightest degree.
Attempts have been made to apply the mortar to hollow bricks by spreading the mortar by means of a pencil, but this has also resulted in an incomplete contact of the joint surfaces. To apply a great quantity of mortar to hollow bricks in walls or floorings in the same manner as in case of common solid bricks is also inconvenienhsince the surplus of the mortar in such case will flow down into the cavities of the bricks, all the more as relatively thin mortar must be used.
The object of this invention is to remove said inconveniences by spreading the mortar across the surface to be coated by means of an implement so constructed as to apply the mortar in a thin layer of uniform thickness only on the surfaces to be covered with mortar.
To obtain this result any implement may be used, preferably, however, such one consisting of a plane plate or the like provided at one or more edges with two or more pro jections or teeth.
Serial No. 481,703.
Several embodiments of an implement adapted to carry the method into practice. are illustrated in the accompanying drawing in which I Fig. 1 shows the implement in combination with a support or boX for the brick.
'Fig. 2 is a plan View of said support 0 box; and, I I
Fig. 3 is a section on line GH in Fig. 2.
In order that the brick when coated with he mortar shall be quite regular, that is to say, that its opposite surfacesshall be parallel and its angles right, even if the stone in itself be somewhat irregular, a device is pro vided which adapted for use in connectionwith the implement'or trowel. Said devicemay consist of a support for the brick, said support being provided with guides for guiding the brick, the upper edge of the guides projecting so, far beyond the surface in question as corresponds to the thickness of the coating of mortar.
Referring to the drawing in detail said support consists of a box 7 in which the brick 12 is placed and supported by supports 8. The upper edges of the guides or guiding ribs 9 lie in a plane a distance above the top of the brick corresponding to the thickness ofthe layer of mortar. Said guiding ribs may also be placed outside the box or on another level, provided that the trowel 1 be constructed for that purpose. The ap-. paratus is preferably placed in relation to the mortar container 5 as shown in Fig. l. the surplus of the mortar falling down in the same. Preferably the apparatus is somewhat inclined. It may be made of wood or of iron or other material.
The cavity of the bricl s is filled with a core 10, the upper edge of which is on a level with the guiding ribs 9, and by means thereof the mortar is prevented from falling down into the cavity. The guiding ribs 9 and the walls of the box 7 prevent the mortar from falling down onto the outer sides of the brick and soiling the same.
The apparatus shown in the drawing is without movable parts, and the brick may be laid down directly into the box. If the bricks are very heavy or relatively high or if from. other reasons it will be difficult to lay them down into the box, either the suptili i a u u to be raised or lowered, the brick thereby being raised or lowered, or the box and the core may be raised and lowered in relation to the brick. The apparatus mayalso be slid onto or shut over the brick.
This apparatus affords among other things the advantage that it requires less skilful ness in use, it being less difficult to apply the mortar on a top surface than on a more or less downwardly inclined surface.
The manner of operation of the implement will, it is thought, be easily understood from the above description and therefore further description is deemed unnecessary.
