FLOOR, SIDEWALK,

ROQF, AND LlKE SUPPORT.

Specification of Letters Patent.

Patented May 21, 1907.

Application filed November 23,1905. Serial No. 288,823-

To all whom it may concern:

Be it known that L'PETER H. JACKSON, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Floor, Sidewalk, Roof, and Like Supports, of which the following is a specification.

My invention relates to supports such as are employed in floors, roofs, sidewalks and the like, and in which metallic bars are so united as to form a sash for the purpose of supporting illuminating glass embedded in cement, forming at the same time a wear ing and bearing surface, and a means 'or lighting the space beneath.

My invention consists in the combination construction which of parts and in details of will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a perspective view showing my invention. Fig. 2 is a view showing supporting bars.

One method for making the iron sashes is to use flat bars set on edge, these bars being perforated or slotted intermediate of their depth. Other flat or shallow channeled bars are passed through these slots; these second bars lying in a horizontal position, and the whole structure forms rectan gular spaces in which the glass is supported. A filling of cement is afterward placed in around the glass.

The ends of the bars which stand on edge have been projected over the top of the concrete walls or irches upon which the structureis supported, and it has been customary to allowathe edges of these bars to rest directly upon the concrete. Fravel, moving of weights by wheeled trucks or otherwise upon the surface, soon causes these edges to cut into the concrete supporting wal which is frequently made in such proportions as to be a poor resistant. Then these bars are thus cut into the concrete, the structure depressions take place and leakage occurs.

it is the object of my invention to overcome such a dilliculty.

In my patent of January 12, 1904, No. 7 49,440 I have shown the glass supporting is unequally supported, becomes loosened,

structure formed 0 bearers made of sheet metal bent into channeled form, and having bases of considerable extent, and the cross bars are let into the tops of these channeled bars. The ends of the channeled bars where rolled plates or they project over the supporting walls or arches are let into slots made in the vertica portion of anglciron bars which rest upon the supporting wall. This structure 1s somewhat expensive to manufacture, and it is the object of my present invention to make a cheap sash in which ordinary fiat bars may be employed, standing upon edge to receive the horizontal y disposed cross bars which pass through slots in the edge bars, and to provide a continuous support for the ends of the edge bars whereby they are prevented from entering into the concrete or other supporting walls.

In this structure are metal bars having slots cut transversely through them at proper intervals, and through which slots extend the flat bars or shallow channeled iron bars 2 so that the bars A stand on edge, and the bars 2 lie horizontally and serve to support the edges of the glass illuminating tiles, which when the space between the tiles has been filled with cement will comlete the structure.

The ends of the bars A standing on edge are extended sufficiently to rest upon the concrete or other wall 3 which forms the support for these ends.

in my invention 1 interpose between the edges of the bars A and the supporting wall, angle iron bars 0 metal 4, of such width as to form a suliiciently broad support upon which the edges of the bars A rest, and by reason of the considerable surface thus presented, the edges of the bars A are prevented from cutting or wearing into the supporting wall.

The vertical flanges of the supporting bars 4, are slotted at intervals which are equal to the distances which it is required to have between the bars A to receive the illumination tiles, and the channels thus serve as spacers by which the bars A may be rapidly and accurately set, the transverse bars 2 being iixed by the equally spaced slots through which they pass and are slidable in the bars A.

The bars A remain their full depth and are not cut away or weakened where they rest upon the plates 4.

Having thus described my invention, what I claim and desire to secure by Letters Patentis In a structure of the character described, flat single metal bars standing on edge having longitudinal slots intermediate of the top and 2. 854,502 bottom ed have hereunto set 0 subscribing Wit- I 5 In testimony whereof I my hand in presence of tW member lying upon the Wall, said bars havin nesses.
