REGISTER TOP PLATE.
`rtunentetl Nov. 17, 1914.
Application led May 12, 1914. Serial No. 837,998.
T0 'all whom it may concern.' l
Be it known that I, HOWARD S. HART, a citizen of the United States, residing at New Britain, Hartford county, State of Connecticut, have invented certain new and useful Improvements in Register To \Plates,'of which the following is a full, clear, and exact description.
y invention relates to a perforated top platefor registers, ventilators and the like, the m'ain object beiner to improveV the same as to strength and eiciency. u
In the accompanying drawings, Figure l is a top plan view of one corner of my improved top plate as it would appear in place. Fig. 2 is a view of the under `side of said plate. Fig. 3 is a section on the line 3 8 of Fig. l. Fig. 4 is afsection on the line 4 4 of Fig. l. Fig. 5 is a section on the line 5 5 of Fig. l. Fig. 6 is a section o-n the plane ofthe line 4 4 showing a modification.
The plate is .made from sheet metal and may be of any `suitable outline, although preferably it is of rectangular, form. The plate is perforated to provide a multitude of air passages for heating' or Ventilating In order to secure the greatest efficiency, it is essential that the air passages shall be as large as possible without unduly weakening the web, or perforated part of, the body. In the most highly developed form, the air passages should be rectangular or parallel sided except at the corners, which latterA are rounded.
l represents the border portion of my improved top plate, the central part being perforated as shown so as to provide bars running lengthwisel and cross wise of said plate. Theperforations may be formed by powerful presses or dies which cut away a portion ofthe metal and which deform the remaining bars or grids so as to bendvthem into the shape shown in Fig. 4, in which 2 2 represent said bars in section and 3 represents the side of one of the bars running transversely to the bars 2 2.
It will be observed that the bending of the metal is carried to such an extent as to force the two sides of each bar into contact, that is to say, the two sides are pressed together at the lower edge of each bar for the greater portion of the length of each of said bars. As shown, the down turned sides do not engage at the junction points of the cross bars 2 and 3 3 where, as seen in Fig. 2, there are small pockets or cavit1es 4 4, `each pocket being bordered by inwardly curved downturned walls 5 5 which are integral with down turned walls 0f the adjacent radiating bars. bridge the corners and since they are integral with the side walls of the bars, they constitute a powerful reinforcing means at all iunction points.
Smce in registers and ventilators it is highly important to provide a maximum space or passage for the air, it is apparent from the foregoing that the total area o-f the The walls 5 5 serve to air passage reaches its maximum by forcing the side walls of the grids gagement as shown. In order to reduce the danger of breaking the meta-l at the bend in the forming of the plate, it is preferable that the side walls do not engage each other flatwise throughout, but merely at the lower edges, as best seen in Fi 4, there being a very slight cavity left directly under the curve of the are, as shown. By my improvement, there is very little space afforded for the accumulation of dust or dirt. In some instances it may be desirable to reinforce one or bars into enor more of the cross bars and to that end I may provide the modification shown in Fig. G, in which 6 is areinforcing bar or brace placed on edge, one edge of said reinforcing brace 6 projecting into a channel on the under side of the cross'bar 2, the side walls of which, instead of -being brought together at the lower edge are closed down on to the sides of the brace 6 as shown. Such a modification is desirable in thel case of large register plates used for floor registers whereinthe plate shouldv have a powerful load carrying capacity. Said` reinforcements 6 may of course be used only at such intervals as the occasion requires, which would be determined largely by the thickness of the sheet metal used and the weight that the plate is designed .to support.
It will be observed that all the cross bars between the junction points are arched, or in the form of an inverted U-shaped 'cross-section, with the lower edges pressed into contact. By pressing the edges into contact as shown, it will bc apparent that the danger of buckling is avoided to a large extent (even when comparatively thin metal is used) since the contacting side walls tend to reinforce and support one another.
In the preferred construction as shown CJi ' sides of ysaid bars being Vclosed together, eX-
herein, all of the bars are arranged in alineinent tliat is to say, the bars running lengthwise of the plate are arranged in line and thepbars ruiming transversely are'also arrangedl in line,raltliough l do 4not Wish to limit myselfl to this lspecific arrangement-in all cases.
While I have shown my improved top plate in its perforated forni, some changes and modifications may be made without de rparting from the spirit and scope of the iiivention.
' What I claim is:
1. A sheet metal top plate for registers, ventilators and the like, comprising a plate havingV 'a border portion and a perforated central portion` forming cross bars between rsaid perforations extending from border to border in both directions, said bars being .arched in ycross-section, the llower part of the sides of said'bars being closed together.
2. A sheet metal toprplalte for registers,
ventilators and the like, comprisingy a platel having' a border portion and a perforated" central portion forming cross bars between said perfoia'tions extending rom'border to border in bothdirections, said bars. being archedin'cross-section, the llower part of the `central portion,
side Walls of each barbeing slightly sepa rated adjacent to; the inner Wall at the top l.
of the arch. l
4f. A sheet metal top plate for registers, ventilators and the like, comprising a plate having a border portion cross from border to border in both directions, the
sidesof a plurality of said bars being pressed together to afford mutual support against buckling and to provide maximum air space. HOWARD S. HART. YVitnessesz' j l J. E. MiDDLE'roN, E. C. GOODWIN.
