.GRATED STRUCTURE.
SPECIFICATION forming part of Letters Patent No. 380,069, dated March 27 1888.
Application filed February 1, 1887. Serial No. 226,202. (No model.)
To all whom it may concern:
Be it known that we, MICHAEL HOFFMAN WILSON, of Nutley, in the county of Essex and State of New Jersey, and WILLIAM DAVIES THOMAS, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Grated Structures, of which the following is a specification.
This invention relates to grated structures generally,which are composed of metal strips having great width in proportion to their thickness, and which are set up edgewise and arranged at angles to each other, the two series of strips being notched and engaged with each other at their points of intersection; and these grated structures may be employed for flooring, mats, fences, and window protections.
The invention consists in a grating composed of two series of strips, each having notches, in the edges of which are offsets, and havingtongues deflected from the sides of the strips beyond the bottoms of the notches, the said two series of strips intersecting one another attheir notched parts and the tongues of one series engaging the offsets in the notches of the other series, as particularlyhereinafter described, and pointed out in the claim.
In the accompanying drawings, Figures 1 and 2 are respectively a plan and a vertical section of a grating embodying our invention. Fig. 3 is a side 'view of a portion of one of the said strips or bars, and Fig. 4 is a side view of a portion of a strip or bar which is presented at the opposite face of the grating from that shown in Fig. 3.
Similar letters of reference designate corresponding parts in all the figures.
AA designate, respectively, two intersecting series of parallel metal strips, which may be of stout hoop-iron or thin flat bar-iron, or of other metal of substantially similar form, the strips having great width as compared to their thickness. These strips or bars are set up edgewise, and the two series may be engaged with or intersect each other at any convenient an-. gle, although they are represented in Fig. 1 at right angles.- Each of the said strips or bars A A has in it at certain intervals a series of notches, a, of a width equal to or slightly greater than the thickness of the bar. The notches extend half-way through the width of the strip or bar from one edge thereof, and in one side of each of these notches is an angular recess or offset, b, and in'each strip or bar be- 5 5 tweenthe end of each notch or and the opposite edge of the bar there is a tongue, 0. This tongue is formed by cutting or punching in the bar a slit which forms three sides of a quadrangular figure, but leaves the other side (So of the figure undeveloped, as shown in Figs. 2 and 3, and pushing out the cut portion laterally from the face of the bar, as shown in the upper parts of the bars A in Fig. 2. The two series of bars A A, which, it will be seen, re- 6 5 semble each other, are put together with thenotches a, in one series upward and corresponding notches in the other series downward, so that the notchedportions of one series engage with the notched portions of the other series, and each bar of either series is pushed into the notches of the other series until their corresponding upper and'lower edges respectively are all flush or in-the same planes. In thus putting the two series of bars together the tongues a, being in some degree elastic, pass through the outer ends of the notches a, and thence spring into the recesses or offsets b thereof, so that the two series of bars are not only engaged with their intersecting notches, but said engagements are locked, so that it will be extremely difficult to disengage them.
Additional security is given to the engagements of the two series of bars or strips by soldering at the notched intersections. This soldering maybe effected by the process known as tinning or galvanizing the structure after the strips or bars are put together.
203,356, which shows a structure formed of paper-board or pasteboard, and having in each strip a tongue lying in the same plane withthe strips, and adapted to be deflected so as to engage a slot formed in thestrip beyond 5 the bottom of the notch. Our tongues 0 do not lie in the same planes with the strips, but are deflected from the sides of the strips and We are aware of patent to McCarren, No. 0-
engage offsets or shoulders 7), formed directly in the edges of the notches a, and not slots in the body of the strip beyond the bottom of the notches, as in McCarrens patent. McCarrens 5 invention might be possible with flexible material, such as pasteboard or card-board, but it would be absolutely valueless with metallic strips.
What we claim as ourinvention, and desire [O to secure by Letters Patent, is
A metal grating composed of twoseries of strips, the strips wide in proportion to their thickness, each having notches a, in the edges of which are ofisets b, and having tongues a deflected from the sides of the strips beyond 15 the bottoms of the notches a, the said two series of strips intersecting one another at their notched parts, and the tongues c of one series engaging the offsets b in the notches of the other series, substantially asand for the pur- 2o pose herein described.
