FREDERIO H. MOORE, OF BOSTON, MASSACHUSETTS.
BRIDGING FOR FLOORING-JOISTS.
SPECIFICATION forming part of Letters Patent No. 459,900, dated September 22, 1891.
Application filed April 13, 1891.
T0 alt whom it may concern:
Be it known that I, FREDERIO H. MOORE, a citlzen of the United States, residing at Boston,1n the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Bridging for Floorlng-Jolsts, of which the following, taken'in connection with the accompanying drawings, 1s a specification.
Bridging for flooring-joists as now employed somet1mes consists of pieces of board or plank the exact length of the distance between the o sts and of about the same width as the oists, which pieces are arranged in a line and nailed to the joists; but the bridging most generally employed consists of pieces of timber about two inches square, the ends of which are cut at an angle, so as to abut against the sides of the joists. Two of these pieces are arranged between each joist and are set so as to cross each other. If the ends of these pleces are not cut to the proper angle, they do not have a fair bearing and the bridging 1s defective.
The object of my invention is to produce metallic bridging which Will be more efficient and easily applied.
The invention consists of bridging-pieces of metal, preferably of wrought-iron, bent at the ends to the required angle and nicked, bent, or halved, so that they will interlock when placed diagonally between the joists, the ends being provided with holes, so that they can be nailed to the joists, as hereinafter fully described.
Figure l is a perspective viewshowing two joists and metallic bridging embodying my invention. Fig. 2 is a side view of metallic bridging, and Fig. 3 is a plan of same before they are placed together. Fig. at is a perspective view showing two joists and a modified form of bridging. Fig. 5 is a plan View of two parts before they are put together. Fig. 6 is a view showing another modified form of bridging. Fig. 7 shows the two parts before they are placed in position. Fig. 8 is a detail view.
A A represent joists; B B, the metallic bridging. I prefer to make the bridging of flat wrought-iron, bent at each end to fit against the joists, as shown at b, and in the center on one side of each piece is formed a nick 0, so that when the two pieces are adj usted together they will interlock one with the other, as best seen in Fig. 1. The ends 1) Serial No. 388 780. (No model.)
are each formed with holes, preferably two, through which the nails are inserted to secure them to the joists.
In Figs. 4 and 5 I have shown metallic bridging formed of round iron bars B B. In this case the ends I) are flattened and bent to the required angle to fit against the joist, and the bars are at their center bent to a half-round, as shown at 0, so that when they are adjusted in place they will be firmly locked together.
In Figs. 6 and 7 I have shown a modified form of flat metal. This consists of two pieces B B each bent to a V shape, and having their ends I) bent to the required angle to abut against the joist. The piece B at its apex is formed with a small V-shaped recess 0 to receive the apex of the piece B so that when adjusted as shown in Fig. 6 the two pieces are securely locked together.
If it is desired to employ a flat plate of very light material, a rib may be struck up in the center of the bar to give additional strength, as shown at d in Fig. 8, which is a view of one end of the bar.
Bridging thus constructed will be more effectual and permanent than the Wooden pieces usually employed, and there is a great saving of time and labor in applying them.
By the employment of my improved metallic bridging, should there be, as is often the case in practice, a slight difference of width between the different joists, the metallic bridging can be sprung so as to expand or contract, as the case may require, and when interlocking pieces are employed the joist between the two pieces forms a fulcrum for the expanding or contracting of the said pieces. Of course various sizes would be required for joists of different depths and distances apart.
What I claim as my invention is- Bridging for flooring-j oist, consisting of two pieces of metal having their ends bent to abut against the joists and interlocking one with the other at their center, substantially as set forth.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 4th day of April, A. D. 1891.
FREDERIO H. MOORE.
