METHOD. 0F HOLDING BUILDING BLOCKS.
Application filed November 16, 1926. Serial No. 148,676.
y valuable where the material or aggregate used is sufficiently light and porous to admit of the application directly upon it of plaster or stucco,or the application of wooden trim etc., by nailing,- as may be done in the well known cinder block construction.
The 'block of -the present invention is ca` pable ofv manufacture on a machine equipped with a double row ofl tamps, one row tamping the material or aggregate in the mold at the front of the cores, the other tamps working. at the back thereof. The tamps are also preferably varied in weight to eifect variation in the tamped density, and when desired the density of the Wall portion formed by the heavier tamps mayfbeifurther improved by the use of a vibrating plate or wall like that shown in my co-pending application, Serial No. 148,674 filed Nov. ie, 1926.y
Referring to the drawings illustrating one preferred method of carrying out myinvention- Fig.` 1 shows in plan view a characteristic form of building block. indicating the relative density at front and back respectively;
Fig. 2 is a vertical sectional view showing' the mold of a molding machine and itstamps adapted to produce said block;
' Fig. 3 is a view similar to Fig. 1,-showire a Irlllfidified construction with a thinner front Wa 4 is a view similar-to Fig. 2, showing the mold and its tamps for producing such block; l v i Fig. 5 is a perspective view of the building block of Fig. 1.
Referring to the drawings, 2 is the usual mold ofa standard block press mounted upon The other side, being .lessthe supporting plate 3, having the cores L for formation of the usual coro openings a of the block, as shown in Fig. l.
The material for the block A is filled into the molding space in the usual Way, a pallet 5 having been first inserted for removal of the finished block, and the block'is tamped` within the Walls and around the cores by a plurality of tamps 6 and 7 of Well known construction.
For the purpose offeifectino` the densifying action, tamps 7 .are materially heavier than tamps 6, so that, as they fall in the tamping operation, they will crowd the material at that side of the mold closer together, during the time the lighter tamps 6 are doing the same Work at the other side.
In order to bring thefinal tampedbody portion of the block up to a final common level the yaggregate is supplied in a proportionately increased amount at the denser side before or during-the tamping operation. Such operation continues until the mold is completely filled and'tamped up to the desired level, after which any surplus material is removed by shifting iti-laterally across the top of the mold in the usual way.
For the purpose of imparting a smooth finished surface to the denser face of the block, one of the side walls of the mold 2 may bein the formof a longitudinally vi-` y brating plate 8.
Such vibration or alternatin movement of the plate will tend to trowe such face, giving it a' substantially smooth finished surface, in the manner more fully described in thefsaid' co-pending application.
Thevblock may be of any desired dimensions,and the roportions of the walls may be made to 4suit the conditions of use, or other variations may be adopted, within the scope' of the invention, as hereinafter claimed.
Having described 4my invention, what I claim'. is: u v I 1. The process of making a concrete block ofa dense consistency at one side consisting in applying relatively heavy and light tamping'to opposite sides of the entire block while the mold.
2. The process of making a concreteblock of a dense consistency at one side consisting in simultaneously Ifilling and tamping oon-` crete aggregate of normally uniform consistency ina mold with a relatively greater amount of condensation at one side..
' 3. r1`he process of making a concrete "block 5 of a dense consistency at one side consisting in simultaneously lling and tam'ping concrete aggregate of normally uniform consistency in a mold with a relatively greater i amount of condensation and a relatively thinner Wall at one side.k I
In testimony whereof I hereunto allix my signature.
