r The presentinvention 'relates to wall construction, and is particularly concerned with,

wall construction for partitions and the'like, The present application isparti'cularly con- "5 cerned with amodified' form of a base'block shown in my Patent No; 1,681,311, issued August 2 1, 1928.

' One of the objectsof the invention is the provision of a novel wallconstruction, including a base block having rounds for plastering formed thereon, said lock being formed with shoulders for aligningzrwall'core and having abottom similarlyformed so as to make the block reversible and to'simplify the l5 installationJ" Another object is theprovision of a base block constructed of any magnesite composition which is readilyseverable and whichincludes grounds for plastering and longitudi- 2 nal recesses closed by baseboard'sfor enclosing wiring conduits and the like."

sition, such as for example, the compositions of matter described in my co-pending "appli cation, Serial No. 295,593, filed July 26th, 1928 f on wall construction. Such compositions-of matterare readily severable by ordinary tools,thereby permitting the base blocks to be sawed oflito fit them in-place between doors, windows or other walls, and about pipes'or conduits in walls. "This composition of matter also possesses theproperty of re ceiving nails and 'permitting other parts to be fastened 'theretoby'lneans of nails -0 screws without 'splitting the block.

' Referring to the drawing, 1 O- indicates I in its entirety a wall construction made accordingto'the 'pr'esent invention,*including a 'lurality' of baseblocks11,a' wall*core 12, as'e boards '1'3'and 14, and plaster coats 15 and 16. I "The base blocks 11; comprise molded magnesitemembersythe mold of which-is PlOf vided with a coreto formi arecess-17 for'the purpose of saving material and providing a dead air space in the block. I 5

, I The base b1 ks 11 arepreferably provided with the'relatively flat upper and lower-sur faces' 'ls, either-fofwhich may e' used =for supporting {the wall core 12 thewidthiof eithercsurface 18 being substantially equalto the-thickness of the brick, tile 'orother 'mac terial of'which the partition is to becom StructedQ' V a On each side of the surface 18- the block is provided with a shoulder 19, which may slope slightly outwardif desired, and which is adapted to align the wallcore 12 with the blocks 11. Adjacenttheshoulders 19 .on each side the block is provided with the plaster engaging surfaces 20, which are of a width substantially equal to the plastencoat or coats, which are to be applied to the wall, and the outer fiat surfaces 21 and; 22 of the block may thus'be employed for grounds in plas- It should be noted that the shoulders" 19 automaticallyalign the wall corerelative to a moved at any time to inspect thewiring or the laster grounds 21 and 22, and it isabsolute y unnecessary to use any furring strips for forming plaster grounds, thereby elimi Dating a great deal of labor in the building of the wall. a relatively strong construction between the base block and wall core, since the shoulders positively prevent the wall core from getting out of place relative to the block.

In order to make the block reversible so as to simplify its installation, the bottom18 of the block may be provided with similar shoul ders 19, similar surfaces 20 and similar plaster grounds 21 and 22, and the plaster coat engaging surfaces 2Q mayjform the surfaces upon which the block restswhen used in'a wall. In the construction of the wall, it is thus immaterial which side the artisanm'ay grasp and much time is saved in the installation of the base blocks since it is unnecessary to turn them over-or to lay in any particular way and either of two sides may serve as the bottom or top.

The base blocks 11 are preferably provided with longitudinally extending recesses 23 on one or both sides, and these. recessesmay be curved as in Fig. 4:, or formed by three or more flat surfaces 24,25 and 26 as in Fig. 3. In either case'fsufiicient material should left ontheside of the block adjacent the top and bottomto form the plaster ground's 22, and to form a surface againstzwhich a base board 13 or 14 may be secured.

Fig. 4 is a modified form .of base block 11 of substantially the same shape as that shown in Fig. 2,but having curved lateral recesses 23 for receiving wiring conduits or the like. 1 Referring to Fig. 2, itqwill thus be noted that after the wall has been constructed, and the plastercoats 15 and 16 applied, the baseboards 13 and 14 of wood, marble or any convenientmaterial, may be used to close'the recesses 23. The recesses 23 may be used for installing wiring conduits27 for electric light wires, gas pipes, water pipes, or loose wires,

such as are used. in 'annunciator systems. When the wiring or plpingzhas been inv stalled the baseboards 13 and l l may be 'secured by a plurality of screws 28 passing through the baseboards and screwed into the base block, and as the base block is constructed of a material which will readily receive screws, the baseboards are thereby firmlyv secured and they may be readily-reto install further wiring or pipes. v The wall construction may also be provided with quarter-round molding 28', and with any other appropriate molding 29 above thebaseboard, the latter being also'secured by diagonally driven screws 30, screwed into the. base blocks 11 at points betweenthe screws 28.

' It'will thus be observed that'I have invented anovel form of base block, whichis The shoulders 19 also provide 7 provided with plaster grounds for automatically locating the plaster surface, and with longitudinal side recesses closed by the baseboards for receiving piping or wiring.

My base block is more easily manufactured and more cheaply installed than any of the base blocks of the prior art, and it provides a finished Wall construction, in which the piping, wiring or other installation is always accessible.

The magnesite block is also readily worked intoany size for fitting between doors or partitions, and it is also adapted to receive nails or screws for fastening the block in place, or securing other parts 'to the block.

While I have illustrated a preferred embodiment of my invention, many modifications maybe made without departing from the-spirit of the invention, and I do not wish to be limited to the precise details of construction set forth, but desire'to avail myself of'all changes within the scope ,of the ap-v pended claims. 1

.Having thus described my invention, what I claim is new and desire to secure by Letters Patent of the United States, is

2. In a wall construction, the combination of'a base block of magnesite composition with a wall core, said block having a longitudinally extending recess in its side for wiring and the like, a baseboard for closing said recess, said block having a wall core supporting surface, plaster coat en aging surfacesandplaster grounds forme thereon.

3. A base blo'ckfor interior partitions com prising a member of magnesite composition, having abody formed with a depression in its top and bottom for aligning a wall core, and a longitudinal depression formed in its side for receiving conduits, saidlongitudi-nal depression being closed by a base board.

i. Abase block comprising a magnesite bodyhaving a flat top and bottom, shoulders carried at each side of said top and bottom for aligning'a wall core, plaster coat'engaging surfaces adjacent said shoulders, and plaster grounds adjacent said plaster coat engaging surfaces.

V J Y 6. A unitary building block comprising a block of nailable material having a longitudinally extending groove along one side for housing conduits and the like, said block having a flat top to receive wall members and having a narrow flat ledge at the ed e in a horizontal plane different from the p ane of the top of the block, for the purpose described. I

7. A unitary partition block comprising a block of nailable material having a longitudinally extending groove at each side thereof to form housings for conduits and the like, said block having a flat top and narrow ledges at each side of the top in horizontal planes ofiset from the plane of the top of the block, for the purpose described.
