J. LANERI TERRAZZO STRIR Filed oct. 5, 1934 Il W 16 IW 7,4 AHMH 16 lNvN-roR Jos-PH LANE ATTORNEY Patented Apr. 28, 1936 PATENT OFFICE TERRAZZO STRIP Joseph Laneri, Brooklyn, N. Y.
Application October 3,
7- Claims.
This invention relates to terrazzo strips.
An object of my invention is to provide a terrazzo strip having highly improved interlocking means for retaining the strip embedded within the terrazzo floor.
A further object of this invention is to provide a heavy top terrazzo strip ofthe character described, having improved means for attaching the heavy top edging member without the use of 1Q rivets or other fastening means.
vide a neat, compact and rugged terrazzo strip of the character described, which shall be comparatively inexpensive to manufacture and practical and ecient to a high degree in use.
Other objects of this invention will in part be obvious and in part hereinafter pointed out.
'I'he invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.
In the accompanying drawing, in which is shown one of the various possible illustrative emb odiments of this invention,
Fig. 1 is a top plan view of a portion of terrazzo flooring, provided with dividingrstrips embodying the invention, with parts in cross-section; 3Q Fig. 2 is a side elevational View of a terrazzo strip embodying the invention embedded in floorlng;
Fig. 3 is a cross-sectional View taken on line 3-3 of Fig. 2;
35 Fig. 4 is a cross-sectional view taken on line 4 4 of Fig. 2;
Fig. 5 is a transverse, cross-sectional View, similar to Fig. 3, but disclosing a heavy top terrazzo dividing strip embodying the invention;
40 Fig. 6 is a perspective view of the strip shown in Figs. 1, 2, 3 and 4; and
Fig. 'l is a perspective view of the strip shown in Fig. 5.
Referring now in detail to the drawing, I0 desig- 45 nates a portion of terrazzo flooring and comprises a base layer I I and an upper terrazzo layer I2, in which there are embedded a plurality of dividing or separating members I4 embodying the invention. The members I4 are disposed in vertical 50 planes and may be arranged in any suitable pattern, as is well known in the art, the upper edges of said members being flush with the surface of layer I2.
The member I4 comprises an elongated, iiat,
relatively thin strip, preferably made of brass,
A still further object of this invention is to pro- 1934, Serial No. 746,640
bronze or the like material. The same is provided with a plurality of openings I5, preferably alternately oppositely disposed. The shape of the openings I5 is preferably of a'truncated triangle. It will be noted that one opening I5 has side 5 edges I6 inclined inwardly and downwardly,VV whereas the next adjacent opening I5 has side edges I6 inclined inwardly and upwardly.
At spaced intervals, the strips are provided with interlocking portions Il. Each portion I'I 10 comprises a tab I8 cut from the material of the strip and bent to incline upwardly and outwardly from the plane of the strip I4. The tab I8 has likewise the shape of a truncated triangle and has upwardly` and inwardly inclined side edges 15 I9 anda top horizontal straight edge 2B. Cut from the tab I8 is an inner tab 2I, likewise hav-V ing the shape of a truncated triangle and bent to incline to a greater degree than the-tab I8. The tab 2i likewise has upwardly and inwardly in- 20 clined side edges 22 and a top horizontal edge- 23. It will be noted that by cutting the tabs I8 and ZI, openings 24 and 25, respectively, are formed in strips I4 and tab I8, to permit interconnection of the terrazzo layer on both sides 25 of the strip I 4 through said openings. Preferably, one interlocking portion II projects to one s ide of the strip I4, whereas the next adjacent interlocking portion Il projects to the opposite side of said strip, as shown in Fig, 6 of the drawing. 30
The terrazzo layer I2 0n opposite Sides Qf the strip I4 is also interconnected through the openings I5. In this manner the strip I4 is rmly embedded in the layer I2. The projecting tabs I8 and 2I serve to firmly hold the strip I4 within 35 the layer I2.
In Figs. 5 and '7 there is shown a terrazzo strip 2 of the heavy top type. The same comprises an elongated strip 3i) made of substantially thin metal; for example, brass or bronze. Said strip 40 3U is provided with openings I5a. and interlocking portions Ila similar to the openings I5 and portions Il of the strip I4. Said strip, however, is provided adjacent the upper edge thereof with a portion 3l bent out of the plane of the strip, 45 but disposed parallel to the body of said strip and being connected thereto by the portion 32. Extending from the upper edge of the portion 3| are a plurality of spaced folded-Over tabs 33 for the purpose hereinafter appearing.
Attached to the strip is a heavy top edging, member 35 of substantial T-shape cross-section, having a relatively thick upper portion 36 and a downwardly extending relatively thin ange 3l, preferably of the same thickness as the strip 30. 55
firmly attaching the member 35 to the strip 30.
It will beV noted that the body of the strip 30 is substantially in a planebisecting the topY portionV 36 of the merriberj35. The Vmember 21may be embedded withinlthe terrazzo layer I2 with the top surface 43 of theY portion 36 of said member 35 flush with the top surface 4of said layer.
It will now be understood that the member 21V will be firmly embedded and interlocked within the terrazzo layer by the interlockingjportions 11a and by reason of the terrazzo material passing through openings 15a. The use of the tabs 33 obviates the necessity for rivets, screws, or
other fastening devices for attachingthe member'35 to the strip 3G. Y Y
In assembling the member 21, the tabs 33 are first bent at right angles to said strip 3D. Said tabs may then be inserted through the slots 38 by a sidewise movement and bent downwardly for rmly clamping the flange 31 tothe strip 3B. It will'thus be seen that there is provided a device in which the Vseveral Objects of this ,invention are achieved,` and which is well adapted tovmeet-the conditions of practical use.
I As various possible embodiments might be made ofthe aboveV invention, and as various changesmight be madein the embodiments vabove set forth,.it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense. Y
Having thus described my invention, I claim asnew and desire to secure by Letters Patent:`
.-1. A terrazzoestrip having a tabrcut from the material thereof and extending to one side thereof andbeing inclined upwardly, and a second tab cut from the material of the first tab and extending to one side of said rst tab and being inclined upwardly and disposed at an angle to said strip and first tab. v
