METHOD 0E PRoDUoINGr BUILDING UNITS.

Application filed October 26,1917. Serial No. l198,725.

To all whom t may concern:

Be it known that I, SAMUEL S. COLT, a citizen of the United States, residing at Orange, in' the county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Methods of Producing Building Units; and I do hereby declare the following to be a full, clear, and exact Adescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being; had to the accompanying drawings, and to characters of reference marked thereon, which form a part of Jthis specification.

This invention has reference, generallyf,fto a novel' body havingl a dash or thrownon, finish, said body being in the form of a unit, block or wall of concrete, or any other body, such as wood, brick or stone, the invention relating more particularly to a novel method of producing and finishing such body.

The present invention therefore has forv its principal object vto provide a novel method or process of body havinga dash or thrown-on finish said body being in the form of a unit, block or wall of concreate,\or any other body, as wood, brick or stone, with a view of providing a most artis-y tic effect, and providing when applied in the formrof a finished structure, an ornate structure yhaving the appearance upon its face of being a construction laid up lin nished stone.

Other objects of the present invention not at this' time more particularly enumerated will be clearly understood from the following detailed description ofthe present invention. Y

With the'various objects of the present invention in View, the invention consists in the production of a novel process ormethod or wallof concrete, or any other body, suchv as`.wood,brick, or stone.

In carryingA outv the methodor process, thennit, bedmar t0 Which-.the fdash or thrown-on finishis 'to be applied can be molded by any system of molding for con"- crete or ,the like,-or may be any rough surface such'as metal lath or wire mesh applied to wood structures, or may be made of brick or rough stone, the dash or thrownon material being generally a mixture of sand and cement., but may be -of other known materials, which, after it is `properly pre-` pared,v is thrownI onto the surface toy any desiredy degree of thickness by theV aid of a -whisk broom or other suitable means,- and sufiiciently dry, then being ground away, or otherwise' removed, to form upon the i Speciiicationv of Iletters Patent.

.dashed-onuor stippledasurface of the? unit,

from the defects usually found present when made b vother methods.

`In the" accompanying drawings, I have illustrated both a unit, in. the form` of a block, and a wall,` representing the finished product, as well as the various steps in carrying out the novel method or process of the invention.

` Referring now moreA particularly tov the several iiguresof the drawings, Figure 1 is aV perspective view of a single Vunit or block molded from concreteor representing v2a roughV stone, or a brick; Fig. 2 is a similar view ofthe same, but having its entire main face or surface provided with ai .dash?? or thrown-on finish or veneering of sand and cement, or the like, and' F ig. 3 is a transverseV or block,ishowing the dash coat face'of the e unit orblock with portions of the" dash,or thrown-on7 finish ground or cut awayianl Fig. 5 is a transverse vertical section of the said unit or block. .1.

Fig. 6 is. a face viewv of anished .wall made according to andv embodying` the principles of the.presentjinventiony and'Fg; p is.'alwriZQnta1-e0tQnal representation ,Qi

the same, said section being taken on line 7-7 in said Fig. 6.

Similar' charactersY of reference are employed in the said above describedviews, to indicate corresponding parts.

In carrying out my present invention, will first refer to Figs. l to 5 inclusive, in Said figures, the reference-character l indicating a unit in the form of a block of concrete which is molded in the usual form or mold in the usual manner. In lieu of a concrete block, it will be evident, however, that this unit l may be a rough stone, or a brick, or other suitable base or body.

rIhe dash or thrown-on finish is indicated by the referenceecharacter 2, and the same consists, generally, of a suitable mixture of sand and cement, or a suitable mixture of other materials, which is properly prepared so as to be of proper plastic consistency, and is then applied to the face or surface 3 of the unit or block 1, by being dashed or thrown onto said surfaceby the aid of a whisk broom or other suitable means.

This thrown-on finish is thereupon allowed to dry sufliciently so as to have the appearance of what is known in the trade as a dashcoat 0r stippleface. After this dash or thrown-on finish is suciently dry a portion of such surface is removed or ground away, as at 4, see Figs. 4: .and 5 of the drawings, the removal of the surface-portion or portions being accom plished by grinding or rubbing away the thrown-on finish to any desired depth by means of carborundum, stone, or any other means, which will produce a smooth and fiat finished surface. A

As shown in the accompanying drawings, in Figs. 4 and 5, the unit or block is provided with a smooth and flat margin, which illustrates one embodiment of the principles of the present invention. It will be evident, however, that other portions of the dashed or thrown-on surface or veneer of the unit or blockmay be ground away or rubbed off, whereby the face of the unit or block is provided with smooth and fiat nishes of innumerable designs.

In lieu of applying the present invention to the production of a single unit in the form of a concrete block, stone, or brick, as heretofore described, the invention can be applied in the production of a concrete wall, bridge-structure, or the like, over a large surface, as will be evident from an inspection of Figs. 6 and 7 of the drawings.

As indicated in said figures, the referencecharacter 5 designates a Vlarge concrete or other suitable'body, made in a form, and 6 designates a dash or thrown-on finish, which is applied in the manner herein-above stated,l over the entire surface or face of naeaeos the said body. When the said finish or veneer is suiiciently dry, desirable portions thereof, as 7 and 8, are ground away, or rubbed od, or otherwise removed, to provide the smooth and fiat surface-portions illustrated in said figures,` and whereby a wall in imitation of laid-up stone is produced.

To more fully enhance the artistic effect, if desired, channels or grooves, as 9 and 10, may also be produced in the smooth and flat surface-portions to represent lioints.

F rom the foregoing description of my present invention it will be clearly seen that I have produced a novel and simple means and method of providing a building unit in the form of a block, body, wall, or other structure, the face of which is provided with a dash or thrown-0n finish or veneer, having a Vportion or portions thereof ground away, or rubbed down, or otherwise removed to a desired depth, so as to provide a flat and smooth margin or other ornamental effect, and which will cause the dashcoat to stand out in bold relief; and, furthermore, by my novel method of producing the same providing clearly defined forms and shapes of increased ornamental design and effect, free from defects and such as are not at present by the methods in ordinary use.

I claim sn Y 1. The method herein described in producing a buildingunit comprising a body in the form of a block, wall, or the like, which consists in applying to the face of said body a dash or thrown-on finish, Vand then grinding away a portion of said finish.

2. The methodherein described in producing a building unit comprising a body in the form of'a block, wall, or the like, which consists in applying to the face of said body a dash or thrown-on finish, and then grinding away those portions of said finish lying adiacent to the'marginal edge-portions of said body to provide a fiat and smooth margin. Y

3. The method herein-described in producing` a building unit, by molding a-body in the form of a block, wall, orthe like, of concrete, stippling` the surface of said `body and grinding away a portion of the stippled surface to produce a bold relief of said stippled surface. Y,

4. The method herein-described in producing a building unit, by molding a body in the form of a block, wall, or the like, of concrete, stippling the surface of said body, and grinding away the marginal portions of the stippled surface to produce a bold relief of' said stippled surface.

5. The method herein-described in pro-l ducng a building unit, by molding a body of concrete in the form of a block, wall, or the like, dashing or throwing onto a surface of said body a Veneer of concrete, and grinding away a portion of said Veneer.

6. The method herein-described in producing a building unit, by molding a body of concrete in the form of a block, wall, or the like, dashing or throwing onto a surface 10 of said body a veneer of concrete, and grindingaway the marginal edge-portions of said vveneer. A y
