To allwhomz'tmayeoncernh '.Be it known that I,"JAMES L.WooDARD,

acitlizen of thezUnited States,.residing at Oakland, `in the `county `of` Alameda and Statelof California, `have inventednew and l useful Improvements in Building-Lumber, of whichthe following isa specification.

' This invention relates vto masonry buildings,`-an'd has for its `obj ect lto lprovide improved means `and' method for the erection thereof.` l y It isan object to provide a .readymeans for building walls, `partitions and floors, also y roofs, having the advantagesofmonolothic construction without requiringthe `use of.

molds, and which will befof a: simple 'char acter` such as will notl necessitate .skilled artisans for itsfuse. i l v' It isan aim to evolve a buildinglumben which, --without specialframe workfor its support,`imay be utilizedin conjunction .with

suitable concrete mixtures for the building i of walls, partitions, floors, and the like; v

lty is a particular aim to enable the utiliza` tion `of waste products in wood mills, although fthey invention is alsol well `adapted toy be formed `terra cottaand other plas- Additional objects and advantages will be apparent `from lrthey followingY description andgfromthe'drawings,"in which#- l Figure 1 is a sectionalview of afbuilding constructed in accordance with myV invention, Fig. 2 is aLfragmentarysectional View showing the .anglel at the junction of `two walls, Figi is al. detail side view ofa piece of my lumber, Figi -L is an end view thereof,

Figf is a side view of a modification,zutiliz-` l ing small scraps'of'wood, Fig". 6 is a 'frag` mentary side View of a'wall constructed with i a further modiication of the lumber, partly in section f l i .i There is illustrated a building including the foundation 10, ron which Va `wall 11 is carried,l iioors 12 and aroof,` 131 being supported by 'the wall.` There partition '14 shown. 1 f .i Y.

The foundations are constructed in any suitable manner, and upon these for the outerl walls" there are llaid longitudinally the lumberbeams or stringersl which are is also a ,central built up from a numberl ofstrips 16 of 11n- BUILDING-Linunnu..` i

Patented bec. dressed lumber the rough splinterysurface of `which increases its hold on` concrete. The edges are alternately' indented or ady .justed 'to lie inwardly-of the edges of the intervening-boards :orstrips 16,' on each side, andatthe ends, as seen in Figs. 3 `and 4; The boardsA orv strips are Vsuitably:secured together in each Stringer; l The thickness of the stringers from edge to edge of the strips may be proportionate tothe'character of thc wall or-partition to be constructed.

`For small buildings, the stringers are built upon one another over the wall foundations to form wall cores, being adapted to be cut and'fitted between window'frames,

las will be apparent.. A temporary means may be employed to hold thelumber walls `in place until the concrete is applied, which would enable the lumber cores to be built to `a more `advanced stagethan otherwise,and

theconcrete'put on over larger areas. How- `ever',fit is'possiblefto build up a few feet ofthe core and then apply theconcrete', by which method no temporary supports for thelumber are necessary. lPartitions may be'` built in thesame mannerjfif "desired, though a series ofpiers `may be utilized fori their supportin place"Tofa'icontinuous foundation. The walls may alsobe `supported in the same manner; `Alliighterfor nar-- rower stringere maybe employed for `the partitions than for outer walls. "When put#` ting'in floors, they may be of the usual con-f struction if' desired, `theends ofv the joists being rested upon lthe wall cores 'at 'the proper height, and the cores builtptherebetween and continued above, as described.

Or, my stringersmay be utilized for the conf struction ofa concrete" floor, byextendin'g them kacross the space vbetween' two walls, their staggered edges being. presented up# wardly and downwardly. Or the" lumber may be utilized between I beams,.as will be understood without illustration. `A roof may be constructed by extending my stringers from the ridge to the tops of walls on opposite sides.

The concrete `1s'v applied tothe lumber after it has been put in position, by means of a trowel, or other customary'methods of like purposeg: In this way the 4lumber may ber completely incased on all sides, protect i ing it from climatic eects, insects, and lire,

. and when the lumber is used as a roof base,

a concrete roofmayvb'e easily formed. ,The formation of the ends of the stringers allows the ready formationk of eaves Compltly.,

incased in concrete, as willy be understood.

In Fig. 5 there is shown a modification in which the stringers are formed of boards or strips 16 spaced apartby small blocks .18', which may be spaced inI staggered relation,

or in alinement transverselyofthe stringer,y

suitably spaced from one edge or side, at least. i lThis enables the utilization of small scrapqblocks and 'requires less wood. The

first described form of lumber also allows that the projections 2O and recesses 'havek therebetween the same relative 'position'sand be so arranged as to'interlock at their ends, as shown; The projections may be of the dove-tail form on thesides, as hasbeen customary in terracotta lumber, and by forming the'end projections and extending the groove 22 thus formed through the sidev projections,

the concrete mixture will have ready access to the opposed grooves of the interlocked ends, lwhereby they will be forciblysecured together. The coengagement of the blocks will be attained, not by the adhesion tothe blocks vof the cement in the concrete, but by theresistance of thevconcrete to compressive strain between the opposed faces of the interloeked portions. On this account-it lmay be found vdesirable to up-end the blocks and let v`the groovesland yrib-like portions extend vertically, or to alternate the arrangement by yhavingfa number of courses extend vertically, and then one or two horizontally, whereby the :wall would betied, so to-speak, in a way to form a more rigid structure. If desired, blocks may `be provided having transversely extending grooves and ribs on theirupper and lower faces, adapted to inf termesh with those on the ends of the vertically disposed blocks, and-one or more of these may be incorporatedin the horizontal courses, so that a continuous vertical tieseries of blocks may be formed in a wall.

o -Itwill of course be understood that if desired the 'projecting portions of the wooden strinfgers before described may be formed in the sal-ne way 'as shown inthe terra cotta form, 'and the stringers made infshort units' more or less approximate to blocks;

thei'routerpa'rt to receive` thethi'ckest part ofthe ribs freely therethrough, where the Y 'blocks may ,be `presented longitudinally toward each other fGreIigagement, their use being thus vgreatly facilitated. l Thek ribs on each side and end are opposed to a 'groove on 'the opposite side and end, so thatthe` form of the block is like that of a series of 'superposed rectangular parallelepiped of slight altitude and wide bases having their centers arranged in staggered relation inca common plane vertical to their major medial planes anidat an angle ofgfrtyvefdegrees to their There is indicated atras in .siglas method of insuringl ventilationf'within the walls, consisting in perforating the lumber so that the spaces 27,:*will be: intercommunieating and dryness andy warmth of the building v construction materially enhanced. v

While in Figs. 3 to 6 of the drawings Stringer'v units are shown to be eachlk constructed of'six layers Vof planking or blocks,

ther Y* a smaller or larger number of layers may be incorporatedl .in each #Stringer or Aunit, if found desirablex It is believed, however,

that this is the most practical form for hanl vdling and rapid work. r.Thei-stringers,"are

supplied from the factory `in the .form

shown, each stri-nger being adapted to il on'another sothat 'the *staggered relation of the planks in superposedrunits will :be con tinuous and uniformyand also Aso that one end of the Stringer may be intermeshed with the side of another when both are laid upon a surface "with their tops and bottoms :in alinemen't. 4By Vthis constructionitwill be observed that projecting edgefportionsyof the' plank are never likely to cmeint opposition, so that they-may befalw'aysreadily intermeshed. The A"same is true A of the jections shown .on the unit inFig. i6. What is claimediis: q 1
