18 Claims.

F The invention relates to floors and has as an .object the provision of a wooden floor in which expansion is controlled.

It is a further object of the invention to provide a wooden floor which constitutes a continuous matted surface.

It is a further object of the invention to provide a wooden fioor madeof short lengths of material laid in courses, the elements in each course and adjacent courses being secured together by metal splines interlocking with the material of the elements.

It is a further object of the invention to provide a wooden fioor'that may be laid in mastic wherein buckling and yielding of the elements laterally of the floor will be prevented.

It is a further object of the invention to provide a floor which may be laid cheaply and which will have its tendency to expand controlled irrespecgc tive of any means provided to hold the floor down upon'the base.

Further objects of the invention will appear from the following description when read in connection with the accompanying drawings showing illustrative embodiments of the invention and wherein: t Fig. 1 is a plan view of the flo'or of the inven- Fig. 2 is a perspective view showing a section of subfloor, the ends of certain of the elements of a course and the means used to interlock the elements and courses together; i Fig. 3 is a transverse section of certain of the elements illustrating a modification; Fig. 4 is a perspective section of one of the elements showing a still further modification;

Fig. 5 is a detail sectional view showing a modi fied form of spline;

Figs. 6 and '7 are side views of still further modified forms of spline; and

Fig 8 is a plan view of a modified form of fioor. 7 i

Due to cheapness oi laying and reduction in thickness and weight, in recent years floors have been commonly laid in mastic, A mastic floor saves substantially two and one-half inches of thickness over a construction of the-old type comprising sleepers, cinders filled therebetween, and underflooring. This results in the saving of substantially one story in a fifty story building and in addition the floor is prevented from rotting and consequent settling, and no space is left for vermin to intrude. Floor loads are likewise consequently decreased and fire hazard is lessened. A disadvantage of mastic laid flooring is that there is no control over the expansion of the floor surface and as the result. mastic laid floors are subject to buckling and the units particularly at the outside of the room have been found to shift,

as a result of which defects of mastic floors the moisture content has had to be very closely controlled; I 7

It is well understood that floors nailed to sleepers where the nailing is done conscientiously are not deleteriously afiected by expansion, the expanding being controlled by the multitude of nails. By the present invention a floor may be laid in mastic with all of the consequent advantages and still may have its expansion controlled so as to have all of the advantages of a nailed floor.

As shown the floor comprises a series of courses 10 of elements desirably in the form of tongued and grooved pieces of flooring, each grooved at each end and assembled with the side tongues and grooves in engagement. At an edge of the floorthere is shown a strip 11 which may bear a tongue to engage the grooves upon the ends of adjacent courses of elements or which may preferably be provided with a metallic spline to be described. Such a strip 11, not shown, is desirably applied at the finishing edge of the floor and the strips 11 are preferably screwed or nailed to the subfloor.

After one of the courses 10 has been completed and assembled with the strip 11, a. metallic spline -12 provided .with upstanding ridges 13 is driven into the assembled groove in the end of the course 10 already laid and so driven into the groove that the ridges 13 enter the material of the elements. The body of the spline 12 is desirably substantially the same thickness as the height of the groove in the end of the elements.

After the spline has been inserted into the assembled course, the next course of elements is laid with vtheir ends in position to be driven upon the spline, the entire course being assembled with the 05 tongues and grooves in engagement and being drawn together so as to make tight joints after which each of the elements in the second thus assembled course is driven endwise so as to abut the ends of the first laid course, the driving resulting in the forcing of the ridges 13 in the material at one or both sides of the grooves in the elements.

It will be seen that after the elements are assembled they may be driven upon the spline either singly or in groups, being free to slide at\ their tongue and groove engagements during such driving. Subsequent courses are laid in the same mannen,

As shown in Fig. 2 the spline 12 has ridges upon one surface only but it may be formed as shown no in Fig. 3 with ridges upon both surfaces. When used upon one surface only the spline may be turned to bring the ridges either upon the upper or lower side of the spline.

As shown the ridges upon the spline are preferably formed by striking the material of the spline upwardly, which method of manufacture results in forming-a depression 14 upon one side of the ridge at the base thereof entering into the normal surface of the spline. When so formed an attempt of an element into which'the spline is entered to move laterally as the result of the .force of expansion results in the forcing of the material of the element downwardly into said depression, thus providing an additional interlocking between the material of the element and the spline.

As shown in Fig. 4 a brass angle piece 14 may be inserted into the groove upon the top of the spline, the edge of the brass strip coming to the surface of the floor to provide an armoring of the joint and to enhance the appearance of the floor. When this angle piece is'inserted upon a spline 12' having its ridges upon the upper surface, the ridges 13' may be formed to a short distance only from the edge of the spline, the longitudinal center of the spline being left plain to provide for the reception of the brass angle.

As shown in Fig. 5 the'spline is formed of a T cross section having the ridges 15 upon the lower surface of the web and the extending portion of the T section projecting downwardly between the meeting ends of the floor elements, the portions of said elements below the grooves being cut back to permit of such, assembly. It will be understood that'the T of this figure may be inverted and that the extending portion of the T section may come to the surface between the floor elements to serve as armoring. This form of spline hasan advantage in that the stiffness of the spline additionally serves to prevent any warping of the floor.

In Fig. -6 the ridges 16 are shown standing vertically from the surface of the spline terminating at their crests in sharp edges and the depressions 17 at their bases being formed by the striking up of the material of the ridges.

InFig. '7 the ridges 18 on one side of the spline slope in one direction and the ridges 19 on the opposite surface slope in the opposite direction whereby to resist expansion of the flooring by the same manner of. coaction as the ridges 13 of Fig. 2.

In Fig. 8 is shown a plan of a modified design of floor wherein certain elements are turned at right angles to certain other elementsin each course, producing a block design. The splines between adjacent courses are substantially continuous throughout the extent of the floor and short splines 20 of the same character are placed at theend of each block. In' this form of the invention the ends of the courses as recited in theclaims appended hereto are partially formed of the sides of elements and partially of ends of elements consecutive courses being joined together by the splines 12.

It will be understood that the angle piece of Fig. 4 may be a T section or it may be a simple vertically extending brass strip nailed to the ends of the elements of one of the courses during assembly.

Due to the interlocking of the flooring elements the tongues and grooves between the elements may be omitted if desired to provide a cheap and eflective form of floor.

- angle joint armor may then be placed upon its plain upper surface without interruption of the ridges.

In Fig. 2 is also shown a sectional portion 21 of a concrete subfloor upon which the ifoor may be laid in mastic 22 in accordance with the usual practice in floor laying.

It is preferred that the splines in at least one dimension of the floor shall be actually continuous and integral from one side to the other for the reason that if they extend through only three or four elements, the edges of the elements at the ends of the splines, will be free to expand and the combined expansion'at a plurality of such breaks in the continuity of the splines will defeat the major object of the invention. However in floors of greater extent than the lengths it is convenient to secure in splines, it is necessary to use more than one piece of spline per joint. Also to avoid throwing away useful lengths of spline, it may be necessary to utilize some lengths of less than the extent of the floor. Therefore in the claims the words substantially continuous are to be read, with these requirements in mind,

' to mean as nearly actually continuous as practicable. A

A floor constructed as described is ornamental in appearance, may be laid very cheaply, and being connected by metal at short intervals throughout its extent and extending continuously throughout the body of the floor intermediate of its thickness, the elements will be positively held from movement caused by expansion or by any shifting where the elements are laid in mastic.

The floor may be given an added ornamental appearance by choice of various colors of the elements arranged as desired. 115.

The floor may be laid upon cold mastic troweled upon the surface of the base or each of the elements may have its lower surface dipped in hot mastic as it is laid or the floor may be successfully laid without any means of holding the same to the base. Since the floor comprises a continuous mat with its elements interlocked, it will remain in place by the action of gravity.

Minor changes may be made in the physical embodiments of the invention within the scope of the appended claims without departing from the spirit thereof.
