COLD-AIR .GRATE,
" Application filed September so, 1925. seriain saesa;
This invention relates tonew and useful improvements. in cold .air grates and'more particularly -to-a grate of the above character which isiar'rang'ed upon the interior'of a building thru which cold air passes'. The main object of my invention, is the provislon of a grate of the above character wherein the bars of the grate are disposed at an angle relative to the frame thereof so that the passageway thru .the 'frame is closed to a certain extent whereby a person looking at the grate will not see directly thru the same into the air duct as is usually the case at the present time. p
In air ates in use at the present time the barso the grate are so disposed as to expose the interior of the air conduit and as considerable dirt and dust accumulates in these conduits, and beneath the grate,' it presents a rather unsightly appearance and in order to cover this unsightly appearance my invention provides. means whereby it will be impossible to'look directly thru the grate into the conduit but the efficiency of the grate is not decreased in any way whatever.
With the above and other objects in view,
. my invention consists inthe novel features of construction and the combination and arrangement of parts to be: more fully described, pointed out in the claim; and shown in the accompanying drawings, in which Fig. 1 is a plan view of an air grate constructed in accordance with my invention,
Fig. 2 is a longitudinal section on the line 2-2 of Fig. 1, i V r Fig. 3 is a transverse section on the line 33 of Fig. 1, and
Fig. 4 is a detailed transverse section'illustrating a slightly modified form of the in- Vention. p
In carrying out myinvention, I provide a substantially rectangular plate 1, having its central portion removed ,to provide a' rectangular opening 1 surroundin which is a opening 1 are a plurality of spaced plates 2 which, in the present instance, are formed from sheet metal. The end portions 3 of each ofthe plates are bentsubstantially at right angles'with respect to an intermediate portion 4'. The oppositesend portions 4 of the plates 2 are bent with respect to the intermediate portions 4 and these portions 4 extend transversely of the passages '5 between the plateswhereby to obstruct direct lateral collar 2.. Arrangedwit in the col-. lar 2' and extending transversely of thethrough these passages 5. As shown 7 in Fig. 3the wallportion' 5 of" the collar 2- is partly removed to; provide aninner mouth of the passage adjacent thereto. The
opposite wall portion 6 of the collar has its lower end portion bent inwardly and diago nally supportedby this end portion is a plate 7 which defines a wall of the passage adjacent, thereto. The collar 2 is adapted to fit '65 7 into an op'eningin a wall'or floor of the building with which the grate is associated.
The plates 2 are secured together in spaced relation with respect to each other by strips "6 which extend transversely across the plates and is secured to the end portions 3. The strips Gare equally spaced apart as shown in Fig.1 and secured to the end portion 3 by welding or the like. The plates 2 .have their end portions secured to adjacent walls 7 8 of the collar 6 bywelding or the like.
In Fig. 4 I have illustrated a modified form in which the frame 1 and bars 2 are formed of a wood a supplemental supporting frame 1 being'secured to frame 1 and provided withan outwardly projecting supporting flange 1. The bars'2 'are supported at an inclination with the upper portion of each bar overlapping the lower portion of the succeeding bar so as to obstruct vision straight downwardlythrough the grate.
It will be apparent from the foregoing that I have provided a simple and inexpensive device of this character which will replace the well known grates in use at the v present time and which will overcome the objections of exposing the dirt and other accumulations within the air conduit so that the air grate will present a neat and comparatively clean appearance from the exte- 5 rior thereof. It will also be apparent that the device canv be quickly and readily installed so as to replace'the form of grate in use at the present. I
While I have shown and described the preferred form of my invention, it will be obvious that various changes in the details of construction and the combination and arrangement of parts may be resorted to for successfully carrying my invention into practice without departing fromthe scope of the appended claim.
Having thus described my invention, what I claim is: r
. In a grate ofthe classdescribed. a substantially' rectangular shaped plate having its central portion removed to provide a.sub
stantially rectangular opening,a collar surrounding the opening and having a lower end portion of one Wall thereof turned inwardly, a plurality of plates arranged within the collar and extending transversely with respect to the opening, said plates having corresponding end portions bent substantially at right angles \vithicspect to intermediate portions thereof and opposite end portions bent with respect to the said intermediate portions, said plates providing a plurality of passages and said inclined opposite end portions ofsai'd plates obstructing diroot vision through said passages, a plurah JACOB HAREQ
