sPE'cIFIcaTIoN formingy part of Letters Patent No. 772,476, dated octeber 18,19`o4. Application iiled April Z1, 1904. Serial No. 204,279- (No model.)
To` all wiz/m, zit may concern/.1. Be it known that I, THOMAS PoDMoRE, a citizen of the United States, residing at Wilkesbarre, in the county of L'uzerne'and State of Pennsylvania, have invented a new and useful Building-Block, 0f which the following is i -a specification.
This invention relates to an articial-stone building-block and method of making the Same.
I The object of the invention is to provide an 'I \artificial stone for 'building purposes having a veneer o r exterior finish in imitation of marble, granite, and similar natural rocks.
The invention consists in applying to, the surfaceof the molded block a thin layer of cement and while the latter is s tilLin a plastic condition sifting a quantity of marble, granite, or similar stone screenings thereon, the surface of the stone after the cement has thor--v oughly set'or solidified being rubbed orpolished t0 remove any loose particles or irregularities in the face of the block, and thereby produce an exterior finish resemblingcross- 4cut or. chiseled natural rock. t
, In the accompanying drawings, forming a part of this specification,- Figure 11 is a perspective View of a building-block constructed `in accordance with my invention. Fig. 2 is va longitudinalsectional view .of the block bef ore'applying the exterior'inish. `Fig. 3 is a similar view showing the screenings` on the face of the block. Fig. 4 isl a longitudinal sectional view of Fig. 1.1
Slmilar numerals of reference mdlcatecori responding parts in all the figures of the drawings.
. The block ,5, which ,may be formed of a .mixturerof cement and sand or other suitable material molded into the desired shape, is 'provided with athin'layer of cement 6, on which is sprinkled aquantity of marble. granite, or I similar 'stone screenings 7, the latter being subsequently rubbed or ground to produce the imitationrstone yeneer or,- exterior finish, v (indicated at 8 in 1 of the drawings.)
is claimed In carrying out the invention I place the blocks 5v after they are thoroughly dry 'on a conveyeror traveling platform arid pass the saine under' a receptacle containing cement, a
thn layer of which is deposited on the face of the blocks.l The'blocks are then passed beneath a vibratingscreen and a quantity of marble or granite ,screenings or similar granular material sifted over the cemented face of the blocks, and thence beneath a tamp which firmly presses said' cement.- The blocks are4 then placed in the drying-room,and after the .cement has thoroughly set or solidified the surface of the blocks are rubbed or ground with a stili 'brush or stone to remove any loose particles and irregularities on the face of the same, thereby producing an'exterior finish or veneer resemlbling cross-cut or chiseled natural rock, as
illustrated in Fig. 1 of the drawings.
It is obvious that the Veneer may be applied to the blocks either before or after the latter are molded, and it is also obvious that any suitable granular material may be deposited on the surface of the blockinstead of the marble and granite screenings shown and described.
Having thus described the invention, what 1s- Themethod of veneering artificial stone or embeds the screenings in whichconsists in depositing a layer of cement f on the face of the block, sprinkling granular material thereon, tamping said granular material, and iinally smoothing the surface of the block by rubbing or grinding the exposed granules so as to present a raised rock face in imitationof cross-cuter Achiseled stone.
' In testimony that I claim the foregoing as my own I have hereto aiiixed my signature in the presence of two witnesses.
