JACOB JACOBS, NEW YORK, N. Y.
BRAGING FOR SIDEWALKS, &c.
Specification of Letters Patent.
Patented July 30, 1907.
Application filed January 29,1906- Serial No. 298,428.
To all whom it may concern:
Be it known that I, JACOB JAeons, of New York, in the county of New York and in the State of New York, have invented a certain new and useful Improvement in Bracing for Sidewalks, &c.; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which Figure 1 is a plan view of a side-walk embodying my invention; Fig. 2 is a plan view of the bracing of such walk; Figs. 3 and 4 are sections on the lines 3-3 and 44 of Fig. 2; Fig. 5 is a view showing the elements of which my bracing is constructed, and Fig. 6 a detail view in cross section, showing the provision of, a nonslipping surface for the braces when used for floors and side-walks.
The object of my invention has been to provide a bracing for side-walks, floors, walls, etc., which shall be strong and cheap, and which shall be readily adapted to cover vault openings of different dimensions with a very small amount of cutting of the elements of my bracing, and shall also be readily adapted to form bracings of different strengths with elements of a single size, and to such ends,
My invention consists in the bracing for side-walks, etc., hereinafter specified.
In carrying my invention into practice, as illustrated in the drawings, I provide main braces A in the form of T or I-beams which are connected by crossbraces 13 that are preferably in the form of T-beams, or which may be in the form of I-beams. The flanges and webs of the cross-braces are provided with T-shape slots 0, of a size adapted to receive a flange and portion of the web of the main braces A. The crossbraces may be shifted along the main braces, to form any desired spacing, so that the bracing shall be as strong or as light as desired. If the cross-braces are placed close together, the bracing will be stronger than if they are placed far apart. The braces may be riveted together, if desired, and either or both braces may be provided with holes a, b, respectively, through which may be threaded wires or rods D for the better support of cement E, when the latter is used to fill the spaces between the bracing to form a side -walk or wall. The cement locks the bracing together, and prevents any relative movement of the parts. Of course, any other 1 below or above the main braces.
flooring could be used in place of the cement, such as a wooden flooring laid upon the top of the braces. The bracing of a ship may be constructed in the manner illustrated. The cross-braces may be placed either The cross-braces may be made in the form of simple bars having no flanges. It will be seen that the portions of the cross-braces which have the T-shape slots formed therein are not materially weakened by the slots when such braces are placed below the main braces, since the flanges b are placed under compression between the webs a of the main braces. The portions of the webs c of the crossbraces which are subjected to a tensile strain are not injured by the slots.
Where my brace is used for side-walks and floor construction, for example, in order to provide a non-slipping foothold or surface, the tops of the beams may be covered with caps F, of lead, which may be in the form of a bar having depending side flanges that embrace the opposite sides of the beams. I
Having thus described my invention, what I claim 1. A bracing consisting of the combination of braces having flanges, and braces having T-shaped slots opening through to one side thereof, said flanges being received in said slots.
2. A bracing consisting of the combination of main and cross-braces both having flanges, the crossbraces being provided with T-shape slots opening through to the side there' of, said slots being for the reception of the flanges for the main-braces.
3. A bracing consisting of the combination of main braces and cross-braces, both having flanges, said crossbraces having T-shape slots extending through and under the flanges of the cross-braces, said slots being adapted to receive the flanges and webs of the main braces.
4. A bracing consisting of the combination of a series of parallel main braces, that are T-shape i-n crosssection, a series of flanged cross-braces having T-shape slots extending through and beneath said flanges of the main braces, said main braces being threaded through said cross braces.
5. A bracing, consisting of the combination of main braces having flanges, and cross-braces having slots adapt ed to receive said flanges, said braces having caps applied to their outer edges.
In testimony that I claim the foregoing I have hereunto set my hand.
.TACOB JACOBS.
