Be it known that LWILLIAM H. BROWN, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Illuminated Antislipping Walk-lVays, of which the following is a specification.

The object of my said invention is to provide in such structures as sidewalks, areaways, &c., used in situations where it is nec-' essary not only to provide a walkway, but to illuminate the space beneath, a construction which will be safe for passers-by to walk upon withoutdanger of slipping. As is wellknown, sidewalk-lights as usually constructed are quite dangerous in this particular, especially in wet or snowy weather, at which times the glass surface, as well as-the surface of most materials of which settings for thelights are made, is very slippery. Lead when properly arranged is peculiarly adhesiveto the soles of boots and shoes,and my present invention consists in a peculiar construction and arrangement whereby lead is utilized bothas the setting for the glass lights or similar parts and as the contact-surfaces upon which the boots and shoes of passers-by will rest, as will be hereinafter more particularly described and claimed. It will be understood that in all cases where in this specification and the appended claims I make use of the term lead I mean to be understood as including any equivalent soft metal which may be used for the purpose.

Referring to the accompanying drawings, which are made a part hereof and on which similar reference characters indicate similar parts, Figure 1 isa perspective View illustrating the use of my said invention and also another invention in a sidewalk; Fig: 2, a top or plan view of one section of my improved sidewalk material as I have constructed the same ready to be put in place; Fig. 3, a top or plan view of one corner of such a section, showing the full size which I have made and design to make the'sarne; Fig. 4, a transverse sectional View on the dotted line 4. 4 in Fig. 3, showing the construction more clearly; Fig. 5, a plan View similar to a portion of Fig. 3, the central portion being broken away and showing a horizontal section as the same appears at the intersection of the squares at points indicated by the dotted line 5 5 in Fig. 4; Fig. 6, a detail sectional view on the dotted line 6 6 in Fig. 3; Fig. 7, a view similar to Fig. 4, illustrating an alternative. construction; Fig.8, a View similar to Fig. 5 of the construction shown in Fig. 7, and Fig. 9 a detail sectional view similar to Fig. 6 of the construction shown in Figs; 7 and Son the dotted line 9 9 in Fig. 8. V

In said drawings the portions marked A represent the framework, 13 the glass lights, and O the lead portions.

The frame A is preferably of cast-iron and is in form a sash,within the apertures of which the glass or parts B are to be secured. The preferred form of this frame or sash is best shown in Fig. 4, in which the ribs or those portions rof the ribs which extend up between the edges of the glass are of a dovetail forma tion for the purposeof securelyanchoring the lead portionsO. This form, however-{being somewhat diiiicult to cast may be changed and the ribs given the form shown in Fig. 7, in which case horizontal holes are made and become anchored by the resulting crossbars 0, as is best shown in Figs. 8 and 9.

The spaces in the sash are of course of suflicient size tonot only receive the lights of glass, but also the setting; and in order that said lights shall be held to position centrally within the apertures which con tain them while the setting is being inserted into place I provide low lugs a in the corners of the spaces, against which the lower portions of the corners of the lights or parts B shall immediately rest when putin place. Theselugs hold said parts B in position until the lead forming the setting has been put in, and thus an even distribution of the lead around all the edges of the same is insured.

The lights or partsB are shown as rectangular, but they may obviously be of any other suitable form. They are beveled somewhat upon their edges, in order that the lead setting may be enabled to hold them more securely in place. I have shown said lights or parts as also recessed somewhat upon the under sides; but they are or may be in themselves of an ordinary and well-known form.

through said ribs at their intersections, int-o which the molten lead usually used will' run The portion (1 is formed of lead (or, as above stated, of other equivalent soft metal) and is inserted in around the lights or parts B, holding the same securely in place, and is also form ed to project somewhat above the surface thereof and form the tread upon which the soles of the boots or shoes of passers-by will ordinarily come 'in immediate contact. The ribs or parting-strips r of the frame are made low enough so that the portions immediately over them shall be of considerable thickness, thus giving a large amount'of ma terial and enabling these parts to endu re long \Vhen the ribs are formed asshown in Fig. 4:, such formation is in itself entirely sufficient to lock or anchor the parts firmly together. When the formation is as shown in Fig. 7, then the holes through the ribs at may enter said holes, and thus be firmly ananchored in place. The method of putting the lead portions C in positionwhich'l have adopted and prefer is to provide a plate con taining grooves corresponding tothe'desired projection of the lead above the general surface of the structure, secure said plate ,over

the. frame or sash after the parts B are placed in position, and-then pour the molten lead into the resulting openings or. interstices, which wi'llthus become filled thereby, as shown, and

after the lead has becomecooledthe removal of the mold-plate leaves the structure complete and'ready for use.

Sucha structurehas been proved by actual test to be highly eificient for the purpose; The projecting lead portions will wear a considerabletima; and by-the time they become worn down the glass surfaces of the interveninglights will becomeabraded and rough, so as to be in themselves, in large measure, nonslipping, while of course the lead intervening' strips will always maintain their nonslipping-characteristics.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in an illuminated antislippingwalk-way, of the frame or sash divided by low ribs into suitable spaces to receive the light-s, said lights mounted therein, and the lead portions surrounding said ribs and filling the spaces between the edges of said lights and to a point above the surface of, said lights, whereby said lead portions form the tread of said walk-ways,substanthe corners or at other suitable points become necessary, in order that the lead setting tially as set forth. I

. 2. The combination, of the frame or sash, A, havingaperturesadapted to contain lights with ribs, r, dividing the several spaces and small projections, a, in the corners of the apertures whereby the lights areheld centrally therein before the setting is placed around them, said lights, B, and a lead set-- ting, O, placed over said. ribs and between the lightsand serving also as'antislipping strips, all substantially as and for the purposes set forth.
