.PARTITION STRIP FOR COMPOSITION FLOORING Application filed January 31, 1929. SeriaINo. 336,486.

This'invention relates to partition strips for composition floorings of-terrazzo and the like, and has particular reference to that type of strip that isshaped to provide a circle,

a triangle, a square or other ornamental design, the primary object of the invention residing in a simple and positive interlocking connection for the ends of the strip, so that the same may be properly embedded at its 1 lower edge within the usual cement base for the composition flooring and in order that the ends of the strip will not spring apart.

Furthermore, the invention aims to provide an interlockin oint for the ends of such partition strips,w erein the elements there of are formed integral with the strip and wherein the ends of the strip may be rapidly interconnected, and maintained permanently in interconnected relation.

In the drawing, wherein like reference characters indicate corresponding parts throughout the several views:

Figure 1 is a fragmentary perspective,

partially in section of a composition floor structure provided with partition strips, the ends of which are constructed with my novel locking joint.

Figure 2 is a fragmentary perspective of a well-known design of strip, the ends being interconnected through the medium of my improved joint.

Figure 3 is a fragmentary side elevation disclosing the ends of a strip in spaced relation, said ends being constructed in accordance with this invention, and

Figure 4 is a detailed longitudinal section taken substantially upon the line 44 of- Figure 3.

Now, havin particularreference to the drawing, 5 designates a conventional composition flooring partition strip of any particular design and materiaL. In Figure 1, there is fragmentarily' illustrated a fragmentary flooring provided with partition strips of va rious designs. Usually, these strips are pro vided adjacent their lower edges with suitable means to anchor them into the usual cenlient base for the floor surfacing materia Such anchors are however, not material to the present invention, and they are not illustrated. M invention has to do only with a locking joint between the ends of the strip to facilitate their rapid and permanent j oining. In'carrying out my invention, one end 65 of the strip 5 is provided intermediate its longitudinal edges with a longitudinally pro jecting relatively narrow tongue 6, integral with the strip, and being slightly ofiset outwardly at its inner end to provide a shoulder 7 at its inner end. Adjacent the forward end of this tongue 6, the same is formed longitudinally with an outwardly struck lip 8, the free end thereof being towards the inner end of the tongue, as clearly disclosed in Figures 3 and 4. In close spaced relation with the opposite end of said strip 5, said strip is formed with a transversely extending outwardly struck tongue guide 9, and obviously, when the tongue 6 is forced therethrough, as in Figure 2, the lip 8 will be bent inwardly, and as soon as the free end thereof passes beyond the inner edge of said guide 9, the

lip. will spring outwardly, so that said end of the lip will engage said inner edge of the guide to prevent separation of the ends of the strip. By reason of the tongue 6 being offset, the ends of the strip will be interconnected in true alinement, and by having the inner end of the lip 8 in spaced relation to the adjacent end of the strip equal to the distance between the inner edge of the guide 9 and the end of the strip adjacent thereto, the ends of the strips will be held in contact with each other.

In view of the foregoing description when considered in conjunction with the accompanying drawing, it will be apparent that I have provided novel, simple and efficient means for permanently interlocking the ends of a partition strip for composition flooring, and even thoughI have herein shown and described the invention as consisting of certain structural features, it is nevertheless to be understood that some changes may be made therein.

Having thus described my invention, what I claim as new, and desire to secure by Letters-Patent, is:

1. In a locking joint for the ends of com- 10 sflsition flooring partition strips, a longitually extending tongue formed at one end of the strip, a longitudinal lip struck from said ton e to provide a shoulder within the 5 length 0 said tongue, and a transverse guide struck from the stri adjacent its opposite end and through whic said ton ue is adapted to be passed the free end of t e tongue lip engafm the inner edge of the guide after thed 1p as entirely passed through said 1 e. 2. In a locking joint for .the endsof comosition flooring partition strips, a longitu- 'nally extending tongue formed at one end of the strip, a longitudinal lip struck from said ton e to provide a shoulder within the length 0 said tongue, and a transverse guide struck from the strip adjacent its opposite end and through which said tongue is adaptgo ed to be passed, the free end of the ton ue lip engaging the inner edge of the guide a ter the lip has entirely passed through said guide, the distance between the inner end of the lip and the adjacent end of the strip being substantially equivalent to the distance between the inner ed e of said guide, and the end of the strip adjacent thereto so that the ends of said strip may be maintained in substantially abutting relation. v :0 In testimony whereof I aflix my signature.

WILLIAM G. KELLEWEAY.
