SIDEWALK-LIGHT.

Specification of Letters'latent.

Patented Dec. 31,1912.

To all whom it may concern:

Be itknown that I, FREDERICK L. Hnoomas, a citizen of the United States rein the county ofMonroe and State of New York, have invented certain new and useful Improvements in Sidewalk-Lights, of which the following is This invention relates to sidewalk lights and has for its object to provide a construction comprising a knocked-down iron frame work and glass lenses .therein isolated from each other, which construction is watertight and in which a bro-ken lens can be readily replaced without disturbing the otherlenses. These andother objects .of my invention will be fully illustrated in the drawings, described in the specification and pointed out in the claims at the end thereof' In the accompanying drawings, Figure 1 is a perspective view of the iron framework which constitutes a part of my invention. Fig. 2 is a section on the line 2 2 of Fig. 1 with the glass lens in place.

In the accompanying drawings like reference numerals refer to like parts.

7 The frame is composed of a system of main bearing bars 1 which are made quite deep and which have stiffening flanges 2, 2 on eachsid'e thereof at about the middle line thereof. These mainsupporting bars are recessed at suitable intervals as indicated at 3 to receive the cross bars 4:, 4 which are also suitably recessed as indicated at 5. These cross bars are provided with bottom flanges 6, 6 on each side thereof. The recesses in the main bars and the cross bars depth that when the parts are assembled the flanges 6, 6 on the cross bars will come on a level with the flanges bars 1. When a series of main bars and cross bars are assembled they will form between them a series of pockets having four vertical having flanges projecting inwardly therefrom, all of said flanges being on substantially the same level. The tops of the cross bars occur preferably slightlybelow the tops of the main supporting bars, as 'is indicated -in Fig. 2, so that the top of the main supbe battered down so as to porting bar can cross bars in place.

receiving or provlding an opening for the Fig. 1, the flanges 6, 6 are cut away at right angles to the cross bars. If desired the flanges 2, 2 may be cut away instead or the flanges 2, 2 and 6, 6 may be cut away on a bevel of 45 degrees so as to form a mitered joint with each other, but either of these constructions is objectionable as they weaken the main supporting bars and for this reason the cutting should be confined as much as possible to the cross bars. The main supporting bars 1 are cross or ,X-bars,

I flanges 2, 2 ofv the main bars. As shown in so called, and the cross or transverse bars 4 are inverted T-bars, and when suitably recessed and interlocked or. halved together, the main bars and the transverse bars form between them spaces of uniform size adapted to receive and support the glass lenses therein, through which lenses the light is transmitted through the sidewalk to the opening therebelow. These glass lenses are large enough to almost fill the opening and leave space between the lens and the surrounding upright bars of the frame for a filler of cement.

' In Fig. 2 the lens is indicated at 8 and the cement at 9. A worm of putty 10 may also be interposed between the lens and the supporting flanges of the frame, although this worm of putty is not really necessary except when an old lens must be replaced by a new one.

When the glass lenses are in place as is shown in Fig. ,2 and the spaces between the lenses and the bars are filled in with cement or other waterproof filling material, the sidewalk becomes absolutely waterproof and no water can penetrate therethrough.

walls around them and Furthermore, if any of the lensesbecome broken they can be easily removed and replaced by new lenses without disturbing any of the other lenses that may be supported in the frame, and the new lenses will be as watertight as the old ones.

The glass lenses have the same vertical thickness at 11 on all four sides,and the margin is adapted to rest on the flanges of the bars by which the lens is supported and makes equal contact with all of the four flanges 2 and 6 provided in the opening which it fills.

The structure is set up by placing the main bars 1 in'parallelrelation to each other and placing the cross bars 4 thereupon in proper position, spacing the main bars 1 apart from each disother at the proper projecting above said-bars, and a cement tances. The tops of the recesses 3 in the main bars are then battered down as shown in Fig. 2, for the purpose of looking all the parts securely together. The lenses are then dropped inplace either directly upon the supporting flanges 2 and 6 or upon the worm of putty interposed between the lenses and said flanges, and the spaces between the lenses and the' upright flanges are filled in with cement, as shown in Fig. 2, which cement is leveled ofl even-with the top of the lenses. 1

This application'describes another form of my invention which-is shown in my prior application N o 643,809.

Having thus described "my what I- claim as new and pa-tentable is as follows:

v 1. In a sidewalk light, the combination of parallel ing a relatively main bars, each of said bars havwide vertical flange and a narrow transverse side-supporting and stiffening flange on the opposite sides thereof adjacent the neutral axis thereof, the main bars being solid from thebottom up to a line above and parallel to' the transverse flanges, cross-bars interlocked or halved saidcross-bars having with said main bars,

supporting flanges on each side thereof, said main bars and said cross-bars forming pockets between themhaving said inwardly projecting flanges-at the bottom thereof,

glass lenses supported by said flanges-and invention,

filler filling in the space between said lenses and said bars.

2. In a sidewalk light, the combination of parallel main bars, each of said bars having a relatively wide vertical flange and a narrow transverse side-supporting and stiffening flange'on the opposite sides thereof adjacent the neutral axis thereof, the main bars being solid from the bottom up to a line above and parallel to the transverse flanges, I cross-bars interlocked or halved with and placed transverse to said main bars, said cross-bars having supporting flanges on each side thereof, the parts being joined together, so that the supporting flanges on the cross-bars and'main bars'are substantially on a level with each other, the flanges'on the bars of the one set being cut away to receive the flanges on the bars of the other set transverse thereto, said main bars, and said. cross-bars forming pockets between them having said inwardly projecting flanges at the bottom thereof, glass lenses supported by said flanges and projecting above said bars, and a cement filler filling in the spaces between said lenses and said bars. y

In testimony whereof I aflix my signature in presence of two witnesses.
