SYSTEM OF BUILDING-BRICKS.

SPECIFICATION forming part of Letters Patent No. 740,683, dated October 6, 1903.

Application tied my 4,1903. Vsessi No. 4155.583. on mode.)

To all whom it may concern.'

Be itknown that I, CEcIL NATHAN,a subject of the King of Great Britain, residing at positively interlocked throughout all its partsl by the material of the bricks themselves in addition to the cementing properties of the mortar.

My improved bricks or blocks may be of the ordinary standard or any other conven. .ient size.

My bricks are of two forms mutually interlocking, and a modification thereof forms the quoi'ns, as hereinafter set forth.

Referring to the accompanying drawings,`

Figure l shows the Aform or header in side elevation. Fig. 2 shows the end view thereof. Fig. 3 shows the B form or stretcher in side elevation. view thereof; Fig. 5, a side elevation, and Figs. 6 and 7 end views, respectively, of the quoin; Fig. S, a top view, and Fig. 9 a base view, respectively, of the' quoin. Fig. 10 illustrates a modied construction with rounded angles. Fig. 11 is aperspective view of the bricks assembled, showing the bonding.

It will be seen `that the headers a have two transverse grooves c above and one longitutudinal groove d below, and the stretchers b have two transverse grooves e above and a longitudinal tongue f below.

The quoin g, Figs.' 5 to 9, interlocks with the adjacent bricks and with the bricks above and below it. The quoin g has one crossgroove h and one butt-ended slot i on top My invention relates to a system character- Fig. 4 shows the end and corresponding groove 7c and slot Z in the bottom in reverse positions, Fig. 9.

In Fig. 10 a header a and stretcher b are shown interlocked. Their projections and slots c d e f have rounded angles in this case.

In Fig. l1 the headers and stretchers with rectangular corners are shown interlocked.

The necessity of a quantity of thick mortar is obviated by my construction, and I prefer to use a thin mortar or cement somewhat of the consistency of whitewash applied to the interlocking surfaces. The joinsare thus extremely close and no pointing is required.'

My improved bricks can be manufactured in the ordinary manner, and the special molds required are simple and involve no further alteration of existing plant.

My bricks may obviously be made of any plastic or other suitable material and hardened in the ordinary way. Bricks of special size,-such as half-bricks or bats, are molded to complete angles or fill spaces smaller than the usual size, whereby the need of cutting is dispensed with and a uniform close joining throughout is assured.

Finally my interlocking bricks may be easily set up to form walls without mortar and can be subsequently taken down and set up elsewhere without difficulty or damage to Vor depreciation of the bricks.

Aithough in the foregoing description and in the claims itis assumed that the headers are grooved only andthe stretchers tongued and grooved, yet the relative arrangement of these might obviously b'e reversed without departing from my invention.

In commencing a wall it is preferable to lay a row of headersupon the damp course, thereby securing a better seating and alinement.

What I claim is- 1. In a duplex system of interlocking bricks,

a superior member having two top transverse grooves and one basal longitudinal groove adapted to interlock throughout its entire length with'top projections onone or more inferior members saidv inferior members having basal tongues adapted to engage .with the superior members of a lower'row.l

2. In a duplex system of interlocking bricks, in combination stretcher-s sidewise adjacent and breaking joint, superior transverse grooves and inferior longitudinal tongues on said stretchers, headers basally and longitudinally grooved, each groove adapted to receive the lendWise-contiguous projections of two inferior stretchers at one side and the middle projection of the sideWise-contiguous stretcher at the other side, and transverse grooves on the upper surface of said headers, adapted to receive the' tongues of a superior row of stretchers.

In aduplex system ofinterlocking bricks, in combination stretchers sidewise adjacent and breaking joint, superior transverse grooves and inferior longitudinal tongues on said stretchers, headers basally and longitudinally grooved, each groove adapted to re-
