Specification of Letters Patent. Pgatmbd Aung'. 22, HQQQH Application'led February 10, 1821. Serial No. 443,896.

To all whom t may cofrtcemf'.'

Be it known that l, WILLIAM H. Hass, a citizen of the United States, residing` at 5824 'Harper AAvenue, Chicago, in the county of' Cookv and State of Illinois have invented a new and useful improvement in Gratings,

of which the following is a specification.

My invention relates more particularly, though Vnot exclusively, to ,improvements 1n registers formed as a part of hot 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; and my primary object is to provide a novel, simple and eco-,

nomical construction lof grating, the parts of which may be quickly assembled to form vthe finished structure, and which will be durable land serve its purpose in a satisfactory manner.

Referring to the accompanying drawlng:

Figure 1 is a plan view of a register constructed in accordance with my invention, Figure 2 is an enlarged, broken section taken at the line 2-2 on Fig. 1 and viewed in the direction of the arrows, andy Figure 3 is a; similar view taken at the cline 3-,3 on Fig. 1 and viewed in the direction of the arrows. Figure 4 is an enlarged perspective view of a portion of the register construction of Fig. 1. Figure 5 is an enlarged sechighly tion taken at the line 5-1-5 on Fig. 3 andl viewed in the direction of the arrows; and Figure 6, a broken perspective view-of a portion of one of the similar bars of which the structure is formed. I

lln the particular construction illustrated the register is formed of aframe 7 shown as of general rectangularshape and made from four

bars

8, 9, 10 and 11, each of angle shape as represented in Fig. 2 to provide the depending portion 12 and the horizontallyextending portion 13, the ends of the frame members referred to being preferably mi-` tered 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 9 and 1-1 and spanning the Space from the members 7 to 10 these bars being preferably equidistantly spaced, and a second series of bars 15 shown as extending at' right angles to the bars 14 and into intersecting'relation therewith, from theframe member 9 to the frame member 11. 'llhe bars '14 are relatively wide as compared with the bars 15 as illustrated, each alternate bar 14 containing a series of openings 16 preferably of general rectangular shape as shown, with oi'set portions represented at 17 and `forming shoulders 18, the shoulders 18 being located at the same side of each opening 16 as shown The other ones of the bars 14 are similarly recessed as represented at 19 withofset portions represented at 20 and forming 'shoul-p ders 21, these shoulders being located at the same sides of the openings 19 but opposite to the sides at which the shoulders 18 are located.

p rlhe openings

16 and 19 are shown as ofsuch size as to permit the bars 15 -to be threaded therethrough, and f the shoulders 18 and '21.are so located that these shoulders will extendv into alinement witlheach other in the finished structure, so that the bars 15 may, in strai ht condition,

lbe supported from'these shoul ers as shown.

The bars 15, which are. narrower than the bars 14, contain in their upper surfaces notches 22 which are spaced apart the same distance that the bars 14 are spaced apart and are so proportioned that when the bars 15 are positioned to seat on the

shoulders

18 and 21, the upper portionsof the strips 14 at their recessed portionsextend into the notches 22, whereby the upper surfaces of the

bars

14 and 15 extend in the same plane. The 'opposite ends of the

v bars

14 and 15 are provided with lugs represented at 23 and 24 respectively, these lugs beinglocated'between the upper and lower edges ot the bars and extending through slots 25 in the bars 8 and 10 and through similar slots (not shown) in the bars 9 and 11, respectively, their outer ends bein bent back against the outer surface of -t e frame to securely hold the

bars

14 and 15 in fixed position.

The parts of the grating are assembled by threading the rods 15 through

thefopenings

16 and 19 of the bars 14 and raising the bars -15 and shifting the

bars

14 and 15 relative to each other in crosswise direction, to cause the bars 15 to extend across the

shoulders

18 and 21, with the upper portions of the bars 14 extendin into the recesses 22. After assembly of t e bars 14 and 15 as stated, the

bars extending through the openings in the frame members `provlded therefor, and the lugs thereupon upset and the .frame memf Qtion, the bars of one series containing aperbers united together 'to form a solid traineV structure.

llt Awill benoted that in the particular illustrated embodiment of my invention the ybars 15, by reasonoi the arrangement of the

shoulders

18 and 21 at opposite sides of the

openings

16 and 19, as hereinbefore explained, are held against accidental dispositioned in intersectingrelation and does not require any vfastening?"devices at these points, the bars becominginterlocked in the o desired position by` merely adjusting them relative to each other" toseat the" kbars 15 'on the

shoulders

18 and 21". lf l. .i

lf desired the notches 22""may 'open downwardly instead y of upwardly.r in which case' the upper edges of the'bars'l would extend below the uppersurfacesv of the bars 14,' or,

if desired, in additionfto` the upper opening l notchesy 22v downwardly'f opening notches (not shownj)finll vertical line therewith may be rovided.'y u l hile llhaveillustrated describedv a particularV construction embodying my invention, I o notiwish'tobe understood as intending to limit it "thereto Ias the same may by Letters Patent, is
