GRATING.
Application :liled April 30, 1921. Serial No. 465,653.
Illinois, have invented a new and useful Im' provement in Gratings, of which the follow-v ing/[is a specification.
i y invention relates more particularly, though not exclusively,-to improvements '1n registers formed as a part of h ot-air furnace installations, and more especially to registers which are located in floors and wherein it is desired that the upper surfaces of the various portions of the register extend in the same plane, my primary object being to provide a novel, simple and economical construction of grating, the parts of which may be readily assembled to form the finished structure.
Referring to the accompanying drawing:
Figure 1 is a plan view of a register constructed in accordance with my invention, one corner portion of the surrounding frame thereof being broken away. Figure 2 is an enlarged broken section taken at the line 2-2 on Fig. 1 and viewed in the direction of the arrows. Figure 3 is an enlarged, broken, section taken at the line 3 3 on Fig. 1 and viewed in the direction ofthe arrows. Figure 4 is a broken perspective view of the intersecting bars forming the body of the grating. Figure 5 is an enlarged section taken at the liney 5*5 on Fig. 3 and viewed in the direction of the arrows; and Figure 6, a broken perspective View of one of the s-imilar bars forming one of the sets thereof.
In the particular construction illustrated the register is formed of a frame 7 shown as of general rectangular shape and made from four bars 8, 9, 10 and 11, each of angle shape as represented in Figs. 2 and 3 to provide the depending portion 12 and the horizontally-extending portion 13, the ends of the frame members referred to being preferably mitered together at the corners of the frame, as for example by welding them. Located within the opening'in the frame 7 is a series of bars 14 shown as extending parallel with each other and to the frame sides 8 and 10 and spanning the space from the mem- Ibers 9-11, these bars being preferably equidistantly spaced apart, and a second series of bars 15 shown as extending at right angles to the bars 14 and vinto intersecting relation therewith, from the frame member 8 to the frame member 10. The bars 14 are rela- .tively wide as compared with the bars 15, as illustrated, each of the bars 14 containing openlngs 16 shown as elongated in the direction of the length of these bars, and as equidlstantly spaced apart. -The bars 15, which are narrower than the bars 14, contain, in their upper and lower' surfaces, notches 17 and 18, respectively, these notches being directly opposed, as-shown, and spaced apart to conform to the spacing of the bars 14 'from'. each other, the heights of the portions of the bars locatedvwb'etween opposing ones of the notches 17 and 18, these portions being represented at 19, being slightly less than the height of the slots 16, and the dimension ofthe slots 16 in a direction lengthwise of the bars 14 fbeing slightly longer than the longest cross-sectional dimension of the bars 15, in order that the parts may be assembled as hereinafter explained.
The bars- 15 Iextend through the slots 16 and thus in intersecting relation to thebars 14, the adjacent portions of the bars 14 above and below thel slots 16 therein extending into the upper and lower notches 17 and 18 of the bars 15, the notches 17 being of such depth that the upper surfaces of the bars 15, by
preference, extend in the same plane as the upper surfaces of the bars 14. The opposite ends of the bars 14 and 15 are provided with lugs represented at 20 and 20, respectively,
these lugs extending through slots in the bars 9 and 1l, one of said slots being indi# cated at 21, and through similar slots (not shown) in the bars 8 and 10, respectively,
their outer, protruding, ends being bent :back
against the outer sur ce of the frame 7 to securely hold thev bars 14 and 15 in xed position.
In accordance with the showing in the drawings, more particularly Fig. 4, the slots 16 of the alternate ones of the bars 14 are arranged in staggered relation relative to the slots 16 in those of the bars 14 alternat ing therewith. The purpose, in accordance withv the preferred illustrated embodiment of my invention, is to provide such an arrangement that the bars 15 will extend at one side closely adjacent to the end walls of the slots 16 in alternate ones of the bars 14, and at their opposite side adjacent the end walls of the slots of the ones of the bars 14 alternating therewith, whereby the bars 15 are held against lateral deflection. This feature of the invention is clearly brought out in Figs. 2, 3 and 4 wherein it will be noted p that the bars 15, Sheen ih Fis, 2, extend, at their right hand sides, against the right hand end walls of the slots 16 of one bar 14, and in accordance with the showing in Fig. 3 exr tend at their left hand sides against the left hand end walls of the slots 16 in the next adjacent one of the barsld. l
rlhe parts of the grating are assembled by threadngthe bars 15 through the bereit and lining up thelatter so that they B Xlfld in 'the plan@ of the notches 17 and' 18 and thereupon rotatingthe bars l15 on the bars 14C to cause the bars 151to straddle the bars 14 at the notched portions 17 and 18, as 'shown in the drawings. The bars 14. are
then shifted, alternate ones in oppositedirections, crosswise of the bars 15 to the position shown in Fig. 4:, in which all of the bars extend in the proper position for application thereto of the -members formin the frame 7 which i lien assembledwit the bars to hold them in proper position i' and form therewith a unitary structure.
A grating constructed in accordance 'with my invention not only possesses a high de-V grec of strength, stillness and durabilit for any given amount of metal' 'employe but also maybe constructed vcryec'onomically by reason of the fact lthat they aissembling of the bars with each other does not require the working of the metal at the intersection between these bars after the'bars have been positioned in intersecting relation *and does not re uire any fastening d'e- 'vices at these points, t e bars becoming inter- .locked in the desired position by merely adjustingthern relative to each other vto the positions as stated. While li have illustrated and described a `particular construction embodying my. in.-
vention, l do not wish to 'be understood'as intending to limit it thereto as the same may be variously modified and altered withoutdeparting from the spirit of my invention.
