HARRY F. BAYLEY, OF MILWAUKEE, WISCONSIN.

METAL-FRAME AND CONCRETE SIDEWALK, 8w.

Specification of Letters Patent.

Patented July 14, 1914.

Application filed May 8, 1913. Serial No. 766,424.

To all whom it may concern Be it known that I, HARRY F. BAYLEY, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented cer tain new and useful Improvements in Metal- Frame and Concrete Sidewalks, 850.; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention consists in what is herein particularly set forth with reference to the accompanying drawings and pointed out in the claims of this specification, its object being to facilitate setting of glass-lights in metal frame and concrete sikewalks, vaultcovers and the like, as well as to compensate for contraction and expansion of the lights, and also to make 1t possible to replace a defective or fractured light without disturbing the adjacent concrete.

Figure 1 of the drawings represents a plan view of a fragment of a metal frameand concrete sidewalk having glass-lights set therein in accordance with my invention; Fig. 2, a sectional View indicated by line 2+2 in Fig. 1, and Fig. 3, a plan view of a light holder inverted.

Referring by numerals to the drawings, 1 indicates each of a series of right-angle irons suitably spaced apart and having the vertical webs thereof notched at predetermined intervals for the engagement of trough-like irons 5, the intermatching irons serving to form a frame. Supported on the frame, on edges of the irons 5 to abut one another and the irons 4, are holders 6 for glass lights 7, and concrete 8 is set in said irons 5 and between the light-holders flush with the upper edges of said holders and the lights therein.

Each light-holder is a casting herein shown in the form of a rectangular shell of suitable depth having flanges inwardly projecting from all walls thereof at the bottom to form a horizontal seat 9 for the light 7 laid therein, and horizontal bottom flanges 10 extend outwardly from two opposite walls of said casting toabut a like flange of a similar casting and the irons 4, whereby spaces are provided for concrete filling. However it is within the scope of my invention, as herein claimed, to shape the shell of each holder for other than a rectangular form of light. To prevent lateral play of the light-holders on the irons 5, of the aforesaid frame,

each of said hold= ers is provided with depending lugs 11 that abut said irons.

Each of the glass-lights 7 is of less area throughout than the space within the walls of its holder and being centered on its seat,

a filling of elastic plastic composition 12 other than the concrete aforesaid is poured, in a melted state, between the light and said walls, the thickness of said light being equal to the depth of its holder above the seat therein. The composition, when set, compensates for expansion and contraction of the light and thus the liability of said light to fracture is obviated, this being an important feature of my invention. In case the light should become fractured from any cause or be found defective, it and the elastic filling material may be readily removed from the holder, without disturbing the adjacent concrete, and a new light and filling substituted.

I claim:

1. A sidewalk, vault-cover or the like comprising a metal frame, independent holders supported on the frame and each consisting of a casting in the form of a shell inwardly flanged at the bottom to form a horizontal seat and having outer bottom flanges extending in opposite directions to abut elements of said frame and like flanges of other holders, concrete in which the holders are embedded, glass-lights of less area throughout than the interiors of said holders in which they are seated, and elastic composition filling other than the concrete aforesaid surrounding each light in its holder.

2. A sidewalk, vault-cover or the like comprising a metal frame, holders supported on the frame and each consisting of a casting in the form of a shell provided with depending lugs that abut members of said frame, each holder being inwardly flanged at the bottom to form a seat and having outer bottom flanges extending in opposite directions, concrete in which the holders are embedded, glass-lights of less area than the interiors of said holders in which they are seated, and elastic composition filling surrounding each light in its holder.

3. As an article of manufacture, a glass light holder for metal frame andconcrete sidewalks, vault-covers and the like, the same consisting of a casting in the form of a shell inwardly flanged at the bottom to form a horizontal seat and having outer horizontal bottom flangesv extending in opposite directions, the interior of the holder being of gneater area throughout than the.

light to be secured therein, whereby an elastic composition filling may he utilized on said seat to fill the space above the same between said light and holder;

4:. As an article of manufacture,a glasslight holder for metal frame and concrete sidi Well s, make ver an th l the same consisting of a casting in theform ,of a shell pr vide wi d pe di g l gs, a whi h is inwa dly flang d at he bot om greater area than the light to be secured therein.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, 20

in the county of Milwaukee and State of Wisconsin, in the presence of two witnesses.
