SIDEWALK OR CONCRETE CONSTRUCTION.

To all whom it may concern;

Be it known that I, JULIUS-H. SOHLAFLY, a citizen of the United'States, residing at Can'- ton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Sidewalk or Concrete Construction; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawin making a part of this specification, and t ures of reference marked thereon, in which Figure 1 is a perspective view showing a portion of a sidewalk and illustrating part of the cement broken away. Fig. 2 is a transverse section. Fig. 3 1s aview showing a portion of one of the metallic bars. 1 Fig; 4 is an end view showing portions of two of the metallic bars connected together.

The present invention has relation to sidewalk or concrete construction wherein a series of bars, preferably formed of sheet metal, are employed and so connected to ether that the serles will be held in proper re ation with reference to each other and the construction of the bars being such that great rigidity is produced with comparatively thin strata of cement or other material 'adapted'while in a plastic. state to be applied and afterward arden to produce rigi formation. If in the event a sidewalk or other structure is to be used wherein it is desired to allow light to enter below the walk or structure, the bars are to be provided with suitable apertures for the reception of glass or other transparent or semitransp rent blocks.

Similar n merals of reference indicate corresponding parts in all the figures of the drawing.

In the accom anying drawing, 1 re resents the bars, w ich are substantially o the form shown, and, as shown, they are pro-.

vided with integral diverging flan es 2 and the integral flanges 3 and 4. Sai integral flanges 3 and 4 are extended upward from the bottom or lower portions of the diverging flanges 2, and for the purpose hereinafter described said flanges are located at substantially right angles to the top of the bars 1.

In use the-bars proper are formed of any desired length and are supported in the usual manner at their ends.

In the construction of sidewalks wherein it is desired to have light penetrate through the sidewalk pro erit is dcslrable to do away with all framewor between the extreme edges of Specification of Letters Patent. Application filed October 19, 190 6 Serial No. 288.447.

the walk or, in other words, to so construct the walk that a clear s ace is left between the end supports of the ardless of the location of the structure here- 1n described, owing to the fact that where intermediate framework is employed to prevent the sagging or bending down of the bars,

diate supports have a tendency and to a cat extent cut ofi a greater or less part of the light thereby materially decreasing the amount of light permitted to enter .below the venting the sagging or bending own of the bars 1 they are rovided with the vertical flanges 3 and 4, w 'ch vertical flanges are loand 4, by which arrangement a double thick? ness of metal can be utilized .and said double thicknessof metal located .in substantially true vertical position. For the pur ose .of connecting the'vertical flanges 3 an '4 to- 'gether the flanges 3 and 4 are each provided with the folds or hems 5 and '5 which folds or hem 5 located under the fold '5, by which arrangement the bars 1 are connected together, so that there can be no relat ve movebars 1, when. connected together.

4 It will be understood that other means than the ones shown may be employed for connecting the vertical flanges together, and hence I no not desire to be confined to the exact manner hereinshoivvn, as the only object far as the connecting of the series-of the bars 1 is concerned is to provide means for holding the vertical flanges in roper relation with each other. By providing the integral divergin flanges.2 spaces are provided between t eexposed faces of thevertical flanges 3 and 4, which spaces are for the purpose of receiving the lastic cement or other and preventing any possibility of their buckling or'springing when downward pressure is brought to bear upon the walk or structure and at the same time assistin holding, the vertical flanges in pro r relationship with each other and in sucli manner that there can be no relative movement as between the bars. a

By providing the hems or folds-5 and 5 "and locating one hem over the other the verl tical flanges 3 and 4 are connected together cated in :pairs, as best illustrated in Figs. 2.

material, thereby bin ing the vertical flanges v ars. ,This is true reowing'to the fact that any and all interme- .walk or structure. For the pur ose of preor hems are seated over each other, the-foldment in a horizontal plane, as between the designed to be accomplished or carried out so structure it is a desirable feature to free from framework or other supports.

and at the same timeso connected together "thatwhen plastic material has been placed in proper positionit will form a'support for the vertical edges by reason of the plastic material finding its way under the lowermost hem or fold, and of course the uppermost hem or fold will rest upon the lowermost one, thereby forming a substantial support for both of the vertical flanges and such a support that there can be no relative or slipping movement as between the vertical flanges.

It will be understood that by my peculiar arrangement I-am enabled to construct a sidewalk or like structure wherein sheet metal can be employed, which sheet metal may, if desired, be galvanized, andany desired number of bars linked, connected, or hooked together to'produ'ce a sidewalk of any des'- ed length without any supplemental sup orting-bars located intermediate the ends of the bars.

In the construction'of sidewalks and like. roduce a completed structure that will be rigid and yet at the same time leave the bottom or under side of the. structure practicallgly 3 my peculiar construction I am enabled to construct a sidewalk with comparatively thin strata of cement or like material, and by embedding" the vertical flanges of the metal bars and forming the vertical flanges integral .With the opposite inclined flanges a rigid structure is produced and maintained after the plastic material has become set and hardened. By roviding the diverging flanges 2 the rays of ight permitted to penetrate or pass through the blocks are deflected, -thereby reducing a structure ca able of allowing t e greatest amount of i1 umination, and at the same time produce a structure of great rigidity and of little obstruction to the rays of light! Having fully described my invention, what I claim asnew, and desire to secure by Letters Patent, is-

In a structure for sidewalk or concrete construction, a series of metallic bars, the tops of said bars provided with a series of apertures, transparent, semitransparent or translucent blocks adapted to fit in the apertures diverging flanges located upon opposite sides of the tops and extended downward therefrom, flanges located substantially :11 right angles to the tops and adapted to be connected together, substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of. two witnesses.
