METALLIC FLOOR COVERING.

Application filed November 9, 1916, Serial No. 130,345. Renewed June 18, 1923.

To all whom it may cancer/t:

Be it known that I, SPENCER C. CARY, a citizen of the United States, residing at the city of New York, borough of Brooklyn, county of Kings, and State of New York, have invented a certain new and useful Metallic Floor Covering, of which the fol-, lowing is a specification This invention. is a floor covering composed of metal, the object in View being to provide a Continuous marginal member adapted to impart a finished appearance to an edge por tion of the metal covering.

The marginal member is characterized by a smooth external surface against which the foot or shoe may easily pass over without catching against said member. The member is of channeled form pressed and clamped upon the edge portion of the covering, said channeled member being interiorly stiflened by a stay member, preferably continuous.- This stay member is fastened to the lin rs of a row of units, and the end portions of the stay member are provided with means for closing the open ends of the channel in the marginal member, thus excluding to a substantial extent the admission of dirt, water or other substances from the interior of said channeled member. 7

Other functions and advantages of the in vention will appear from the following detailed description taken in connection with the drawings, wherein- Figure 1 is a plan View of a portion of the metal floor covering with my continuous marginal strip applied thereto.

Figure 2 is a vertical section on the line 22 of Figure 1.

Fig. 3 is a detail View in plan of the continuous stay member.

Fig. 4 is a detail View, on an enlarged scale, of a part of the stay member and a part of one of the links, illustrating more particularly the means for securing together said link and stay member.

Fig. 5 is a detail view, on an enlarged scale, of a part of the channeled member, a part of the stay member, and a part of one link, showing more particularly the manner of closing the open end of the channeled The body of the floor covering is composed of units 10 assembled into rows, each row of units being held together by rods 11 which pass through suitable openings provided in the units of said row. Itis preferred to employ units of the form shown in Figure 1, each unit consisting of complemental halves with inturned lugs, and the rods pass through openings in the halves of the units and through openings in the inturned lugs thereof, but it will be understood that the invention is not restricted to the particular form of unit or the means for tying said units into rows. The units cooperate with links 12, each; link being positioned between the inturned lugs of the complemental members composing the unit. Said links are apertured for the rods 11 to pass through them, and thus the members of the units in the row andjthe series of links employed in connection with said. row are tied together by the rods 11. The links used in connection with rows positionedintermediate the marginal rows of the floor covering are connected pivotally'in the manner disclosed in certain prior patentsgranted to me, but in the case of the marginal row of units 1 employ links of the form shown in Figure 4 of the drawings. Each link is reduced at an end portion to provide a prong 13 and

shoulders

14, 15. The links used in connection with each marginal row of units are assembled and attached in the manner described and so that the shoulders 14 of said links are substantially flush with the units composing said marginal row, the prongs 13 extending a suitable distance from or beyond said units, and the shoulders 15 being positioned beyond the shoulders 14 and intermediate the units 10 and the pron gs 13.

16 designates a stay member consisting preferably of a continuous metal rod or bar, the length of which is equal substantially to the width of the floor covering, and the width of which is less than the thickness of the units 10. This bar or rod is provided intermediate its ends with apertures 17, and the prongs 13 are extended through the apertures of the bar or rod, after which the prongs are bent or turned over, as at 18, whereby the stay member 16 is attached rigidly to the links which serve as the means for connecting thecontinuous stay member to the row of units. The bent ends 18 of the prongs force or clamp the continuous stay member 16 into contact with the shoulders 15 of the links, thus affording a solid bearing for the stay member relatively to the marginal portion of the floor covering. The stay member is posrtloned length-wise of the row of units and substantially centrally.

with, respect to the depth of said units, thus leaving appreciable spaces'or' intervals between the top and bottom edges of the stay tour ofwhi-ch corresponds substantially to the internal contour of the channeled marginal 'm'ember 20', shown more particularly in Figures 1,2 and; 5 of the drawings.

The marginal member 20 is composed of a single'piece ofm'etal which is bent, folded or doubled upon itself so as to produce the channel 21 the edge portions of the metal composing the member 20 being in turned to produce the flanges 22. In the manufacture of the channeled member 20 itis first blanked from a suitable piece of metal, the edges thereof are turned to form the flanges 2'2, and the metal blank is doubled upon; itself. to produce the internal channel. During the manufacture of the member 20 its formand dimensions are such that said member can be readily slipped over the stay member 16 for the purpose of having the desired contact with the links, the stay member and the units, whereby the channeled member enca-se the stay member and the end portions of the links, and said channeled member is substantially flush with the top and bottom members of the units, thereby imparting a desirable finish tothe marginal portion of the metal floor covering. A characteristic feature of this inyention: consists in the usexof a channeled marginal member, the exterior surface of which is smooth so as to preclude the floor covering; from being caught in an object when taking up or laying down said floor covering, and to prevent the foot or shoe from catching against a roughened surface of the marginal member,- the smooth exterior surface of said marginal member precluding the lodgmen't of dirt and other foreign matter upon the fabric.

The channeled marginal member is not attached or aflixed by the use of separate devices to any part of the floor covering, but in the process of assembling the parts in the manufacture of said floor covering, the channeled member is compressed for the purpose of clamping. it rigidly in position relatively to the stay member and the marginal row of units. Asa further result of this clamping operation, the channeled member is compressed at its end portions so as to have engagement with the parts 19 of the stay,

whereby said parts 19 actas' closures to the open ends of the channelin said marginal member. r

Inthe manufacture of the floor. covering the units, links and. rods are'assemb'led'for the rods to tie the units and links together, the end portions of the rods being bent against the units at the end of the row. The stay member 16 is: positioned over the prongs 13 of the links and into substantial contact with the shoulders 15', whereupon the prongs are bent against the .outer surface of the stay member, thus rigidly attachingv the latter to the links and the row of units. The marginal member 20' is now positioned so that it will slide over the stay member, the flanges 2'1 of said marginal; member fitting into the spaces between the shouldersale, 15 of the links. lengthwiseof the stay member and of the row of units, andwhen it is in position, the open ends of said channeled .member are substantially closed by the end portions 19- of the stay member. At this stage in the manufacture of the covering, the channeled member is comparatively free or loose with reference to the units. The marginal portion of the floor covering isnow placed with. in a press of suitable form, and is subjected to pressure, as a result of which the channeled member is compressed and clamped upon the stay member and the shouldered parts of the links. Another effect of the, compressing. operation is'toclamp the end portions' of channeled member upon the ends 19 of the stay member, so that the end portions of said channeled member are in close contact with the end portions 18 of the stay member, and it is to be noted, further, that the flanges of the channeled member are forcedtightl y into the spaces between the stay member and the row of units, the surfaces of the channeled member next to the units being substantially flush therewith.

Having thus fully described the invention, what I clannas new, and desire to secure by Letters Patent'is: I I r 1.
