1 Claims. (or. 94-17) This invention relates in general to metal strips for use in laying composition flooring.
One of the objects of this invention is the provision of a new and novel form of metal strip adapted for use in laying composition floorings characterized by the fact that it has a plurality of indentations, embosses, wings, or ears to act as guides in determining'the depth of immersion of the strip into the floor composition.
A further object of this invention is the provision of a strip of the above type in which the top edges of the embosses, indentations, wings or ears lie in a straight line substantially parallel to the edges of the strip.
A still further object of this invention is the provision of a strip of the above type in which the embosses, indentations, wings or cars provide anchorage means for the strip.
A further object of this invention is the provision of a strip as described adapted to prevent the separation of the flooring composition from the strip and thus prevent the chipping of the edges of the flooring adjacent the strips.
These and other objects, as will appear from the following disclosure, are secured by means of this invention.
This invention resides substantially in the combination, construction, arrangement, and relative location of parts all as will more fully appear hereinafter.
Referring to the drawing- Figure 1 is a side elevational view of the strip of this invention; 7
Fig. 2 is an edge elevational view of the device looking down on it from the bottom edge;
' Fig. 3 is a cross sectional view on the line 3-3 of Fig. 1;
Fig. 4 is a cross sectional view on the line 4-4 of Fig. 1; and
Fig. 5 is a cross sectional view on the line 5-5 of Fig. 1.
It is common practice in laying composition floorings, of the type of which the terrazzo flooring is one form, to divide extensive areas into smaller areas by means of metal strips. This subdivision of composition fioorings results in a floor of bettergeneral apeparances and one which wears better with less tendency to crack. It is usual to provide a sub-base of suitable composition and then support thereon the metal strips in any suitable configurations to provide the desired finished floor design, the most common configuration being squares. The strips which are mounted on the sub-base serve as guides at their top edges in levelling off the terrazzo or other finishing composition which provides the wearing surface.
The device of this invention is provided with indentations and co-acting ears having their top edges in a straight line parallel to the edges of the strip and before the sub-base composition has hardened the strip is forced down into it so that the imaginary line formed by the indentations and ears coincides with the top of the sub-base composition. In other words, the strip. as constructed provides a gauge for the terrazzo or finishing composition, which is then filled in between the strips to the top edges thereof and when hardened the finishing composition is polished. or otherwise completed. The ears and coacting indentations thereby become embedded in the compositions and when they harden' the strip is firmly locked in place against vertical or horizontal shift. The indentations and ears leave openings in the strips through which the composition flows to further aid in locking the strip in place. From the foregoing description the advantages of this strip will be apparent.
Referring to the drawing for a better understanding of the invention one form of the strip is shown as comprising a relatively thin band of suitable material 1. The strip is provided with a series of spaced indentations or embosses which are struck up alternately so as to project on opposite sides of the strip. Thus the embosses 2 project on one side of the strip and the embosses 3 project on the other side of the strip. A series of spaced ears 4 project on alternate sides of the strip and in the preferred form extend at approximately 45 with the plane of the strip, thereby securing the strip against vertical and/or horiv 'zontal shift. The formation ofthese ears leaves the openings 5 in the strip as is clearly apparent from the drawing. The embosses 2 and 3 have their top edges all extending in a straight line parallel to the edges of the strip andv the top edges of the openings 5 also lie in this straight line. The upper edges of the ears 4 also lie in a straight line parallel to the edges of the strip. It will be apparent then that the strip may be pressed into the sub-base composition to such 'a. depth that the imaginary line in the top of the bosses and openings lies in a line coinciding with the upper surface of-the sub-base composition. The ears particularly, as well as the co-acting indentations, serve to hold the strip in place when they embedded in the compositions. The strips. are also firmly bound in place by reason of the composition paming through the openings 5. The ultimately secure and novel locking effect of the strip is thus made aj'product of the co-action of combined ears and indentations together with the passing of the aforementioned 7 composition through openings 5. i
I am well aware that many changes in the details of construction and relative arrangement of parts will readily occur to those skilled the art and I do not, therefore, desirefito be limited except as required by the a'ppended claims.
What I seek to secure by United States Letters Patent is: 7 75 1. A composition flooring strip" comprising a body of thin material haying a series of bosses projecting from alternate sides and a series of struck up ears extending at an acute angle with 1 the plane of the strip, the upper edges 'of said ears lying in a straight line parallel to the edges of said strip.
2. A composition flooring strip comprising a;
the edges of the strip,
4. The structure recited in claim 2t character- 5. In a' composition flooring strip, a body of relatively thin construction having substantially parallel edges and a series of spaced bosses lying wholly within the edges and alternately projecting on opposite sides of thestrip alternated with a series of struck-up ears which altemately project on opposite sides oflthe strip and have their top edges lying in a straight line parallel to the edges ofithe strip.
6. A composition flooring strip, comprising a relatively thin body having a series of bosses alternately projecting on opposite sides of the strip and a series of cars projecting on opposite sides of the strip with their free edges extending upwardly and lying in a plane; at approximately 45 with the plane of the strip, the top edges of said ears lyingin a straight line parallel with the edges of the strip. W T
'7. A'composition flooring strip, comprising a. body of thin material having a series of bosses thereon projecting from alternate sides and a series of struck-up ears extending at an acute angle with the plane of the strip leaving openings in the strip, said ears joining the strip on one edge only and projecting alternately from oppositefsides of the strip.
