FmEPnooF WALL.

To all whmfit may concer-nf f Be it known that I, WILLIAM DRYDEN, a

\ citizen of the United States, yand a resident of the city of New York, borough of Queens,- in the county of` Queens andState of Nev.7 York, have invented a new and Improved Fireproof Wall, of Which the following is a v full, clear, and eXact description.

7This invention relates to fire-proof constructlon, and the object of the invention is to produce a Wall Which will resist the passage of-flame through it.

The invention concernsitself not only with the construction olf the Wall itself, but

also With the blocks out of which the' Wall is constructed.

The invention consists in -theconstuction and combination. of parts to be. more fully described hereinafter and particularly set forthinthe claim. .Reference is to be had to the accompany ing drawingsforming a part of this specification, in which similar characters of reference show the .screen orl Wire mesh Which the block contains; and Fig. 4 is,a vertical cross section through the block shown in Fig. 3.

'Referring-more particularly to the parts, 1 re resents the studdin of the Wall. On the I si es of this studding, locks'2 are' attached I- 40` f Figs. i3 and 4. 'Each block is of substantia ly rectangular form; one of the lon edges l Ion .t e other so as to form a contmuousWall.- The form of the blocks is very clearly understoodfrom and oneof the short edges of this b ook is formed with a ,rabbet groove 3 on one side .of the central plane of the block, a silnilanrabbet roove 4 is formed in the other two edges side ofthe central plane of the block. I

The block maybe considered to be formed of two blocks of halfI its Width, Which are su'-y perposed upon eachother with the edges con.

certric, oi1e,of the half blocks, asl it were, be-

the other half block. These blocks 2 are formed Lof plasterof paris, or a composition of any other suitable material, and em- .bedded in each block, -near its central plane,

thereis rovided a sheet or screen 5 of Wire gauze. his gauze extends to the extreme limits ofthe block in every direction, that 1s,

it extends out to the outermost edge of the rabbet grooves 3 and 4.` At suitable pointsl each block is provided on its inner face with 'projections or buttons 6, and these buttons are adapted to rest against the faces of the studding 1 as shown in Flg. 1. Opposlte the buttons on the opposite or outer faces of each block, a recess 7 is provided, and at these recesses, fastenmg devlces such as nails 8 are rovided, which are driven through 'the locks and intol the studding, as indicated.

The manner of applying'the-blocks to the.

studding is shown very clearly inr Fig. 2;

The blocks are laid together so' that their 'rabbet edges match With each other so as to form a continuouswall or face. ln tlns Way the screen or gauze -5 of each block overlaps at its edges With the corresponding screen or gauze of the adjacent block. I n practice, the outer faces of the blocks 2 are made rough so as to give a hold to hard plaster or y hard flnish Whlch is applied to the sides of the Wall. It should be understood that the bodies of the blocks may or may not be made of fire-proof material, as desired, for even ifY the blocks are not formed of fire-proof material, they have a fire-.proofing effect for the reason that embedded 1n the Wall there 1s a v continuous screen of Wire gauze;` this results from the fact that all the Asheets of gauze of the blocks overlap each other atl their edges, hence, if, from a fire occurring near a Wall, the plaster vbodies of the blocks shouldbecome destroyed andfall away from the gauze,

there will still'remain attached to the stud ding, acontinuous gauze sheet, and this sheet Will resist the passingof `flame through it,

Which is a eculiar roperty of gauze. In this Way I frm aV Wall Which Will glve a hlgh resistance to Haine passing through 1t. Having'thus descrlbed my mvention, l

claim as new and desire to secure by Letters P tent flame prosf partition formed of blocks having olded bodies with sheets of gauze embedded therein, said sheets of gauze being` formed of fine mesh im ervious to' flame and i name to this specification in the presence of veiiappihget itxler ehgeshsllldslsfastnihg two subscribing Witnesses.
