- WALL CONSTRUCTION;

Application filed July 16, 1915. Serial No. 40,251.

To all whomiz't may concern:

Be it known that I, ARTHUR HARDoN- omm, J r., a subject of the Emperor of Aus-' tria Hungary, and resident of New York, borough of. Brooklyn, in the county of Kings and Stateof New York, have invented an Improvement in Wal1 Constructions, of which the following description, in connection with the accompanying drawings, is. a specification, like letters on the drawings re resenting like parts.

y present mventlon 1s a wall construction for channel brick, particularly intended to enable a channel brick type of wall to be laid up at corners, and-is directed in part to certain I features of the invention illustrated I a in my prior Patent No. 1,068,338 of July 22,

' 1913, but which could not be claimed therein, and of my copending application, Se

.rial No. 40,250, filed July 16,1915.

Inconstructing a hollow wall wherein the air spaces or volds are formed horizontally with an ,openpontinuous space throughout the length of a-c'ourse, it is not feasible to use open ended brick at'corners as an open end wouldbe exposed, and prior to my invention: no method of bonding such channel brick and common brick headers was known or practised. However, I have discovered a means of bonding and closing the horizontal ends'of my channel brick with an overlapping header, whereby. such brick may be partly in the pier of each'corner, thus integrallycarrying the channel brick into the corner piers, and preferably having the side of one brick partially close the voids of another, vand requiring only a small filler or v header to close the open end of the channel.

This feature is of especial importance in i that type of channel brick having raised projections on the-upper side which serve to interlock with depending webs of the next superimposed row, such pro ections, of course, being at an angle to each' other at each corner.' Ina square corner such projections will be at right angles and .would.

not permit being crossed and the corner block being on the same mortar joint as the rest of the wall and of the corner pierconstruction; At obtuse angle corners, such projections will be at a similar angle to that of thecorner, as will readily be understood.

Other important features, details of construction, and advantages wlll be hereinafter more fully pointed out and claimed.

-Wh'le I have herein .illustrated'variou close the type shown in my-said modifications of corner construction wherein wherein such channel brick are carried partly into the corner piers or corner edges, thus utilizing the hollow wall construction right in'to thecorners of the wall and obtaining all benefits and advantages in said corners of the horizontal air space construction, if

. desired.

The foundation isdesignated by the reference character 1 on which a lower-mortar course 2 is laid, the type of channel brick illustrated in Figs. 1 and 2 being built thereon as shown at 3 directly into apart of the corner. Each endmost channel brick having the series of projections 4: and 5. on the up per part, and the depending webs 6 on the lower part, may have said uppermost'proe jections readily knocked off by the hammer or the trowel of the workman, to provide a flat surface 7 sufficient to receive the depending webs of the right angled channel brick of the next course. As shown in Fig.

1, the channel bricks 8 have the uppermost projections partially removed to overlap the open ends of the channel brick at right an gles thereto, thus partially closing said voids and leaving the header block 9 to complete said closings. As illustrated in Fig. 2 these header blocks 9 will be bonded at right angles to each other, each block closing a part of the channel in the right hand wing of the wall left partly open by the overlapping of the endmost channel brick 8, and closing the entire end of such overlapping channel brick. The header 9 may be of hollow construction as illustrated in the drawings, or may be of solid brick, in either case the re moval of part of the raised portions or pro jections 4 and 5 enable the adjacent depending webs 6 of one brick to be bonded on the flat surface 7, and the header 9 to also be fitted thereon. As the channel brick of my invention are preferably of standard brick size in height, the appearance of the corner; wall thus constructed is identical with that of a solid brick formation and thus carries out to the greatest extent the hollow construction into all corners and edges.

In the type of channel brick illustrated in Fig. 3, a similar header 9 is shown, the channel brick 12 therein shown, being formed with. one pair of depending webs 18 and 1a and a single pair of raised projections 15 and 16, which latter are partly broken off to leave the flat space 17 upon which the overlapping adj aoent brick and header may be fitted.

In the modification illustrated in Fig. i, a similar header 9 is shown for the corners, wherein the channel brick 18 are formed with a plurality of raised projections 19 and 20 and depending webs 23. The raised portions 19 and 20 are cut off, leaving the flat top part 21 and the relatively thin tie portions 22. As there is no vertical strain on these thin portions 22 they are sutlicient to hold the remaining half portion of each brick 18, being also sufficiently solid to enable a part of the raised portions 19 and 20' to be thus removed.

Fig. 5 shows a still further modification of the type of channel brick illustrated in Fig. 4, and shown in my said co-pending application, wherein similar headers 9 are employed and each channel brick 25 has a single raised portion 26, partly cut away to leave the projecting part 27 of the top of each brick, where it juts into the corner or pier construction, smooth, to permit the depending webs 28 of the next overlapping brick to be positioned.

It will also be noted that the removal of the raised portions on the top of the channel brick, acts as a guide and interlocking for the depending side web of the adjacent overlapping channel brick. in big. 1 for example, the endmost brick 8 on the left wing with its depending web 6 interlocking upon the projections of the lower full channel brick 3, also interlocks with theahutting ends of the raised projections 5 on the right hand lower brick 8, bemg firmly secured there1n by the bonding material 29, and constituting a gage or stop for the next or topmost full channel brick 3 on the right wing. This greatly facilitates corner building and the same advantage accrues in the construction shown by the various modifications of the other figures of the drawing.

While l have only illustrated the corner and interlocking projections could not nor-' mally be built uniformly level with the course, as the interlocking means would prevent saine. Although ll prefer to remove the topmost ribs or projections as illustrated in the drawings, it is also within the scope of certain of the appended claims to remove parts of the depending interlocking means, 2'. e. the webs Whichcould readily be cut by a trowel to span the space of a small rib without injury to'the load-carrying capacity of the corner. Such an arrangementwould obviously be' an equivalent construction to the preferred arrangement shown in the drawings. The vital point of the invention is that channel brick are so combined at a corner where ordinarily the open ends would be exposed, to be bonded with a header having plain sides and ends, such header partly overlapping and bonding the channel brlck 111 ad acent rows or courses andsimultancously closing the openings.

having my channel brick of substantially standard brick size in height, an ordinary brick or brick pier can be used and a brick of each course extended into overlapping bonding and closing relation with the adj acent channel brick course. Preferably, 1 er:- tend the channel brick courses directly into the corner, but it will be readily appreciated that a solid brick corner pier with the headers extended therefrom into the a Having described my invention, what it'll Ell claim as new and desire to secure by Letters Patent is: l 1. Hollow Wall construction, comprising channel brick adapted to belaid horizon-'- tally, forming horizontal open-ended air spaces, said brick having raised projections and depending webs adapted to interlock with adjacent courses, means for the depending webs of one course to overlap the adjacent lowercourse at corners while having said corner course level, in combination with a header of standard brick size to close 'the open-ended air spaces-of each abutting to i brick laid horizontally forming a corner at a corner, with obstructing projections cut' oil from that part of the brick which extends into the pier, and a header to close the open ends of abutting channel bricks.

3. Wall construction comprising two angularly disposed walls formed of channel which the alternate channel brick extend partially across and overlap adjacent angularly disposed channel brick and a header filling the space formed between the ends of adjacent channelbrick and closing the open-. ings in such ends;

4. Hollow wall construction consisting in channel brick interlocked v with; standard sized brick, said channel brick comprising- .a horizontal body portion having dependingwebs inclosing a horizontal air space on one side of said body portion which webs are of a substantially standard brick size in outer exposed-area, raised portions on the opposite sides of the body portion, so that the vertical height of the raised portions and depending webs are greater than the height of said standard sized brick with which the channel brick interlocks, said channel brick having-a part of the raised portion removed.

at corners, whereby the depending webs and standard sized. brick are laid flush in alinement at corners, piers,- and the like, and said horizontal air spaces are closed.

In testimony whereof, I have signed my name to this specification, in the presenceof two witnesses.
