2 Claims. 1

This invention appertains to concrete, terrazzo, magnesium oxy-chloride composition, and like floors or surfaces, and more particularly to a novel method of laying such surfaces and to a novel screed strip therefor.

In laying concrete and like surfaces, it is was tomary to use screed strips to facilitate the leveling of the outer face of such surface and to thereafter remove the strips and finish the surface.

It is therefore one of the primary objects of my present invention to provide pre-cast screed strips formed of the same, or substantially the same material as the floor or other surface and to leave such strip permanently in position, whereby the necessity of removing the strips is eliminated and whereby such strips can be advantageously used as an ornamentation for the surface, it being understood that the strips can be made in various colors, if so desired.

Another salient object of my invention is to provide means whereby the screed strips can be effectively used in the laying of concrete or similar shuffle board or other playing courts, the strips functioning as division members for the numbered zones as well as leveling strips, the novel construction of the strips permitting the outer face of the court to be readily finished or sanded, the strips also functioning to provide shrinkage lines to prevent the forming of irregular cracks in the finished surface.

A further object of my invention is to provide a pre-cast screed strip or other ornamental member for use in concrete or like floors, which embodies a resilient core on which is molded the concrete body portion whereby a resilient or flexible strip will be had which can be effectively handled and shipped.

A further important object of my invention is to provide novel means for insuring the proper adhesion of the concrete or like moldable body on the resilient core, whereby danger of cracking or loosening of the body on the core is avoided.

With these and other objectsin view, the invention consists in the novel construction, arrangement, and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, which drawings:

Figure 1 is a detail vertical sectional view through a fragment of a shuflleboard court and showing one step in the laying of said court, the section being taken substantially on the line l-l of Figure 2.

Figure 2 is a fragmentary top plan View of the court showing one step in the method of making the court, the view being on a smaller scale than Figure 1.

Figure 3 is a view similar to Figure 1, and showing a further step in the making of the court, the

section being taken substantially on the line 3-3 of Figure 4.

Figure 4 is a fragmentary top plan view of a shuffieboard court showing the additional step in the laying of the court.

Figure 5 is a view similar to Figure 3 and illustrating the method of laying a surface, such as a shufileboard court on an existing floor or other surface which is out of level.

Figure 6 is an enlarged fragmentary detail perspective view showing the inner resilient core of one of the screed strips and illustrating the method of treating such core to facilitate the bonding of the concrete or other moldable substance thereon to form a screed strip or other desired ornamentation.

Figure '7 is a fragmentary detail perspective: view showing one of the strips afterthe making thereof.

Figure 8 is a top plan view partly in section showing the method utilized for making precast numbers or other ornamental members, and

Figure 9 is an enlarged detail transverse sectional view taken on the line 9 9 of Figure 8, looking in the direction of the arrows.

Referring to the drawings in detail, wherei similar reference characters designate corresponding parts throughout the several views, the numeral Ill indicates a base or floor on which the shufiieboard court or other surface is to be laid. This base In can either be an existing surface, such as wood, concrete, steel, marble, brick,

stone, etc, or can be newly laid concrete or the like.

After the base ID has hardened (in case of a newly laid floor), the upper surface thereof is treated with a. bonding coat H for sealing the upper surface thereof and for facilitating the bonding or the adherence thereto of the finishing surface which is to be laid thereon. After the bonding coat hasbeen poured, sprayed or otherwise placed on the upper surface of the base, the division screed strips l2 are placed in position on the bonding coat and these strips are secured to the base 10 by said bonding coat, or by a thin mixture of Portland cement in water, or a mixture of Portland cement and finely screened sand and water. It is to be understood at this time that the screed strips l2 are of an exact same height so that the same can be used to level the finishing coat l3 for the base l0. Likewise, any other ornamentation to be used is also placed upon the base 10 and secured thereto by the bonding coat. In the laying of shuffle board courts, pre-cast numbers M are utilized and these numbers are formed in the same novel manner as the screed strips l2. The method of forming the screed strips will now be described and the screed strips themselves form an important feature of this invention. 7 v

In forming the screed strips I2, I utilize a resilient flexible inner core [5 which is preferably formed from a desired length of wood or dowel. A particular type of wood is utilized which possesses the desired resiliency, such as maple or birch.

The outer face of the core I5 is provided with a bonding coat I6 and this bondin coat l6 can be of the same nature as the bondin coat I l,'pre viously mentioned. While the bonding coat I6 is still in its plastic or tacky stage, granules 'I'i are placed thereon. The granules can' be of anydesired material or substance and the bonding coat functions to firmly hold the same in place. Thegranules are preferably of natural "stone or ceramic materials, such as crushed brick or fired clay as used commercially for roofing (granules; or any other such granules can be used. It is highly desirable that these granules be of approximately the same size, so that 'they'will form a single uniform layer in 'con'tactw'ith the plastic adhesive or bonding coat l6. Actually, the individual granules are-fixed to the cores l5 by attachment of their lower 'halve's or sections only. permitting their upper halves to remain receptiveto the cement or like material to be bonded thereto.

After the forming of the cores 15 with the granules I! thereon, the same are placed in suitable forms and the'body'por'tions IE or the strips are cast on the cores. The body portion Iii can be formed from the same material as the surface (3, it being understood, however, that any desired coloring material can be added to the concrete or like mixture.

After the body H! has hardened, an elongated flexible screed strip will be had which can be readily handled or shipped without undue dan ger of breakage.

In forming numbers or other ornamental devices, I utilize the same method "as "employed in making the screed strips. For instance, in mak ing the number 8 (see Figures -8 and 9'), l utilize wooden cores 19 with a bonding coat and gram ules 2t and these cores are arranged so as to 'ef the finishing surface I3 is poured in place. After the pouring of the concrete or like finishing face, the same "is leveled in the usual manner, and the screed strips I2 and the numbers H are utilized to facilitate such leveling. After the finishing surface has hardened, the same can be polished or otherwise treated, and it is obvious that as the screed strips 12 and the numbers 14 are formed substantially from the same material as the surface IS, the entire coat can be readily and easily finished.

While I have shown the screed strips l2 and numbers 14 for a shufiieboard court, it is to be understood that the screed strips can be utilized in laying any desired floor or other surface.

Where a surface is to be laid on an existing floor, means is provided for leveling the upper face of this fioor, when necessary. In Figure 5 I haveshown a fragment of an existing floor 22 and the upper face of the floor is first provided with a bonding coat, after which a thin layer of concrete, or the like, 23 is applied and held in place by said bonding coat, and this concrete or like layer has its upper surface leveled smooth and-111a horizontal plane. The upper surface of the leveling coat (after hardening) may be sprovide'd witha 'bonding'coat 24. The screed strips i2 and the numbers M are placed on this bonding-coat 24, and after the strips andnumbers have been placed in position, then the finishing surface '25 can be poured in .placepver the bonding coat.

From the foregoing description, it can be seen that I have provided a novel and efficient means for laying concrete, terrazzo, or like floors and other surfaces.

Changes in details may be made without departing from the spirit or the scope of my invention, but what I claim as new -is:

'1. A pre-cast screed strip for use in laying co'n crete, terrazzo, and like floors and surfaces, com prising a resilient longitudinally extending core, granules secured to said core throughout the length thereof, and a concrete or like body cast on said core and connected therewith by said granules.

2. A vpre cast screed strip or ornament for use 'in laying concrete, terrazzo, and like floors or surfaces comprising a longitudinally extending resilient core, a bonding and sealing coat on said core, granules secured to thec'ore by said bonding coat and extending the full length thereof, and a concrete or like body'cast on said core and connected therewith by said granules.
