YORK.
CORPORATION OF NEW GRATING OR VENTILATED FLOORING.
Application filed July 21, 1923. Serial No. 652,943.
My invention relates to ventilators or gratings of the type formed by a plurality of substantially straight or longitudinal strips and a number of intermediate or portion 3 to a right angle as shown by the portions 4 in the drawing, and thereby not only reduce the likelihood of particles of dirt becoming jammed at the immediate 5 spacing members separating the. strips, the point of junction between the spacing memgrating being adapted to be used for a variety of purposes, such for example, as on a sidewalk, or to form a floor. The object of this invention is to provide .an improved device of the above class which shall be simple in construction, and capable of forming a good tread surface or foothold in any direction.
The best form of apparatus embodying bers and longitudinal strips, but, since the portions 4 are normal to thelongitudinal strips, a better tread surface or foothold in some respects is provided for edestria-ns walking along longitudinally of t e gratin The. portions 5 of the spacing strips whic lie between the aforementioned portions 4 are shown as being preferably disposed at an obtuse angle to the portions ,4 and mergmy invention at present known to me is il-Jing with portions 4 by proper curves, but it lustrated in the accompanying sheet of drawings, in which,
Fig. 1 is a plan view of a panel of such grating or ventilated flooring; and,
Fig. 2 is an enlarged cross section on line 22 of Fig. 1, parts being broken away.
Throughout the drawings like reference characters indicate like parts. In many of the gratings of the type described above which are in use today the spacing members extend longitudinally but are bent or curved in some particular fashion to keep the straight strips separated. Some of these constructions have been criticised on the ground that there is liability of dirt collecting in the small angle between the longitudinal or straight strips and the spacing members where a spacing member comes in contact with the longitudinal strip. Besides tendin to avoid this criticism, my invention a ords an excellent foothold for destrians, while combining with these virtues most of the advantages of the old constructions.
In the drawings 1, 1, indicate the longitudinal or substantiall straight strips which are separated by t e intermediate or spacin members 2, also generally longitudina in extent but bent .to come in con tact with the adjacent strips 1 at successive and uniform intervals. That portion of each spacing member which is arallel with or contiguous to one of the strips 1 is indicated by the numeral 3. Instead of having the portions of the spacing members intermediate of the sections 3, 3, form acute angles with the strips 1, I preferably bend the spacing member at each end of each parallel will be understood that these portions 5 may be-arranged at any convenient or appropriate angle to the other portions of the spacing members as may be desired. My grating may be formed of any suitable material, but is particularly adapted to be formed from bars of stock material from which the strips 1 maybe cut to the desired length and the spacing members 2 also cut and bent to their desired shape in a press or die. Where the spacing members and longitudinal strips are in contact at staggered portions of the former they may be joined by means of welding or by means of bolts, i'lvets or other appropriate securing devices,usua1ly by rivets 6, 6. I
From Fig. 2 itfwill be apparent that my grating is made'preferably with the s acing members of less depth than, but ush with the top of, the longitudinal strips, all i.
in accordance with the arrangement shown and claimed in Patent No. 1,045,? 95, to Gustav A. Keller, granted-November 26 1912.
Another advantage resulting from the construction above described arises from the ability of the middle portion 5 of the spacing member in each modification to flex without distortion of the longitudinal strips,
bends between portions 4 and 5.
Having described "my invention, I claim:
1. In a grating, a pair of longitudinal strips and a spacing member therebetween, the spacing member having staggered portions thereof parallel and in contact with said strips, other portions substantially normal to the first mentioned portions, and still other portions disposed at an obtuse angle to said second mentioned portions 'of the spacing member.
2. In a gratin the combination with a plurality of longitudinal strips, of a spacing member therebetween having portlons thereof contiguous to said longitudinal strips at staggered points of contact, the spacing member between some of the successive points of contact with the longitudinal strips being provided with more than two distinct bends therein, the spacing member adjacent a contact portion being disposed at a greater angle to said longitudinal strips than is the central portion of the spacing member between the said successive points of contact with the longitudinal strips.
3. In a grating, the combination with a plurality of longitudinal strips, of a spacing member therebetween having portions thereof parallel with and secured to said longitudinal strips at spaced staggered portions of contact, the spacing member between successive contact portions being provided with at least four bends therein, the central portion of the spacing member between successive contact portions being disposed at a smaller angle to the parallel portions than its end portions contiguous with these parallel portions.
4. A floor rating'comprising in combination longitu inal strips and spacing members between said strips, the spacing members being contiguous .to ,the strips for short lengths, other portions of the spacing members at each end of said short lengths or contiguous portions being disposed substantially normal to said strips, and yet other portions of the spacing members between said contiguous portions or short lengths being disposed at an acute angle to said strips but at an obtuse angle to the second mentioned or normal portions 'of the spacingmem'bers 5. A gratingcomprising a number of uniformly spaced longitudinal strips and a plurality of spacing members having portions thereof substantially normal to one another and a third portion to said member longer than one of said first mentioned portions and lying between pairs of said normal portions.
6. A grating comprising longitudinal members and spacingmembers bridged between the longitudinal members, the spacing members comprising staggered portions parallel with the longitudinal members, a sharp and substantially right angled bend at each lend of each of the parallel portions, another portion having two bends therein and join ing pairs of said right angled bends.
7. A floor grating comprising longitudinal strips and spacing members therebetween and contacting with the longitudinal strips along staggered parallel portions, said spacing members comprising portions substantially normal to and at each end of said parallel portions connecting said normal portions, two of said spacing members being joined with a longitudinal strip in the same portions of its length.
8. In a grating, the combination with a plurality of longitudinal members, of spacing members between the longitudinal mem bers, said spacing members having portions contiguous with and substantially parallel to the longitudinal members, another portion normal to and at each end of said contiguous members and of not greater length than one-half the distance between the longitudinal members, and still other portions connecting said second mentioned portions.
9. In a grating, a plurality of longitudinal members, a spacing member between said longitudinal members, portions of the spacing member being contiguous with and secured to opposite faces of the longitudinal members, a second portion of the spacing member being substantially normal to a first mentioned portion at an end thereof and a third portion of the spacing member being spaced from the longitudinal members, and connecting adjacent ends of two of said second mentioned portions.
10. A grating comprising a plurality of uniformly spaced longitudinal parts and other parts disposed between said longitudinal parts, said other parts comprising staggered portions having their faces contiguous with the longitudinal parts, second portions substantially normal to the staggered portions at at least one end thereof, and a third portion connected to an end of a second portion and angularly disposed with respect to .the first two mentioned portions.
11. In a floor grating, the combination with a plurality of longitudinal strips, of spacing members arranged between said strips and secured thereto, each of said spacing members having substantially parallel and staggered portions adjacent said longitudinal strips where the spacing member is secured to the longitudinal strips, other or second portions of the spacing member being sharply bent away from the longitudinal strip at each end of the parallel portions, these second mentioned portions extending only part way across the space between the longitudinal strips, and still other or third portions of the spacing member arranged at an angle to and connected with the second mentioned portion at each end of the third mentioned portions.
