WILLIAM HENRY ANFIELD, OF ST. IJOUIS, MISSOURI.

COMPOSITION FLOOR AND METHOD OF MAKING TI'IESAME.

Application filed June 23,

.construction of a concrete fioor whereby cracking is practically eliminated, and the construction of such a floor is of less expense than similar floors now in use.

In the drawings:

F ig. 1 is a fragmental perspective View of a portion of my floor and base board when complete-d Fig. 2 is a fragmental section of the same in position when in use.

In the construction of my fioor I commence with the concrete floor which is put in by the builder and is indicated by 3 which is the base or foundation for my floor. This base 8 is constructed of concrete and properlyreinforced in the usual way. Beginning with the concrete flooring as put in by the builder,I then lay overthis concrete base a layer of sand and cement and finely crushed stone i. This is for the purpose of leveling up the foundation 3, as it is well known that the cement floor put in by the builder is generally left in a rough and crude state.

After I have placed the layer 4: of sand, cement and finely crushed stone on the concrete base 3 I then apply my improved flooring in the following manner I take a mass of concrete formed of sand, cement and chipped rock, such as marble or granite, and apply it on the layer 4 and completely cover the space to be floored, and make the same of the required thickness, the floor being indicated by 5. The floor or layer 5 is properly smoothed down and levele-dofi and permitted to harden and to form a monolithic floor, that is, it is put on and permitted to harden as one continuous solid 7 sheet. After this layer or floor 5 has hardened it is then surfaced. After it has been surfaced I take a suitable tool or instrument and form channels 6 through the layerv or fioor 5 and partly into the layer l. These channels may be of any suitable or desired width, shape or number so as to give the floor the desired blocked-off appearance. After these channels have been formed I applyoil by means of a brush in the channels, slightly coating the channel walls with oil, and after this operation I fill in the channels with grout, that is, a thin mixture of cement and Water. I then permit the grout to hard- 1'924. Serial No. 721,930.

en and resurface the floor again. The grout maylbe mixed with any colored pigment desirec.

By forming the channels 6 or cutting up the floor as it-were into slabs after it has been layed and finished and filling in the channels with grout, cracking of the floor by settling is prevented, and cracking by expansion is eliminated.

I can also form by my improved method a neater appearance because the channels can be cut smooth and straight and the joints,

after the channels are filled in, are true and accurate. I have found 1n practice that the making of a concrete floor out-of concrete slabs is expensive becausethe slabs must be made at the factory andtaken to the place to be used and layed and great difficulty has been experienced in truing up the joints.

Great disadvantage has also been experiencedin making this kindof a floor and leaving it in one solid piece, in which cases, expansion and settling in a great number of cases has ruined the floor and it has to be torn up. My improved floor can be completely made and laid on the job thus obviating the necessity of making the slabs at one place, and hauling them to the job and laying them. H

In the construction of my improved floor I form at the same time with the floor proper a'base 7 this isformed integral with the floor proper and can be made any height or shape desired, and when the, floor is scored the base-is alsoscored and grouted in, as illustrated in Fig. 1.

In practice I form the levelling layer 4 of ,sand and cement, properly mixed, or sand,

cement and crushed stone, properly mixed. When I use sand and cement I use them in the following proportions, about three sacks of sand to one of cement; and when I use the three Iuse about one sack-of cement, one sack of crushed stone and two sacks of sand, properly mixed with water.

In practice in forming the floor layer 5 I use marble chips and cement, properly mixed, in about the following proportions, three sacks of marble chips to one of cement, properly mixed with water, which is worked down until the top surface shows about 85% marble.

My improvement especially relates to whatis commercially known as terrazzo floor.

Having fully described my invention, What I claim is 1. The improvement in the art of concrete flooring Which consists in forming a base layer, applying to said base a plastic mass of sand and cement, applying 011 said mass of sand and cement after it has set a monolithic layer, forming channels through the monolithic layer and said plastic mass after the same has hardened, and filling said channels with a plastic self-hardening filler.

2. The improvement in the art of floor construction Which consists in forming a concrete base, applying on said concrete base a plastic mass of sand and cement, applying to said mass after it has set a coating of the desired thickness composed of cement, Water and chipped stone and permitting the same to harden as one monolithic layer, surfacing said monolithic layer, forming channels through said monolithic layer and into the mass beneath it, coating said channels With oil, filling said channels with a relatively thin solution of cement and Water and permitting the same to harden, and lastly refinishing the same.

3. The herein described method of producing a concrete floor, consisting in laying a terrazzo concrete surface of the proper thickness, cutting kerfs or grooves in the terrazzo surface after it is hardened, and filling in the said kerfs or grooves With grout.

4. The herein described method of making concrete floor, consisting in laying a monolitchic layer of terrazzo of the desired thickness and permitting the same to harden, and then finishing the surface thereof, cutting kerfs or grooves in the said layer and filling said kerfs or grooves With grout material.

5. The herein described method of producing a floor, consisting in applying to a concrete base a monolithic layer of terrazzo concrete and permitting it to harden, subdividing the said hardened monolithic layer of terrazzo concrete by cutting grooves therein and then fillin said grooves With material.

6. The improvement in the art of floor construction Which consists in forming a concrete base, applying on said concrete base a plastic mass of sand and cement, applying to said mass after it has set a coating of the desired thickness composed of cement, Water and chipped stone and permitting the same to harden as one monolithic layer surfacing said monolithic layer, forming channels through said monolithic layer and into the mass beneath it, filling said channels With a relatively thin solution of cement and Water and permitting the same to harden, and lastly refinishing the same.

7. The method of finishing a hardened monolithic floor or wall surfaces consisting in deeply grooving the surface to separate the same into individual tiles or blocks, filling the grooves thus formed, as if the surface had been covered With separate tiles or blocks.

8. The method of finishing floor or Wall surfaces, consisting in first forming a mono-- lithic surface, allowing the same to harden, deeply grooving the surface to separate the same into individual tiles, or blocks, filling the grooves thus formed, as if the surface had been covered with separate tiles or blocks.

In testimony whereof, I have si 'ned my name to this specification.

\VILLIAM HENRY ANFIELD.
