REGISTER FOR WALL HEATERS Karl L. Bedell, Pasadena, and John H. Hollingsworth, Altadena, Calif., assignors to Holly Manufacturing 00., Pasadena, Calif., a corporation of California Application November 14, 1949, Serial No. 127,102
11 Claims. 1
Our invention relates to a register for wall heaters and is a continuation-in-part of our copending application Serial No. 43,124, filed April 7, 1948, entitled Register for Wall Heaters. Included in the objects of our invention are:
First, to provide a register for wall heaters wherein the transfer of heat from the hot air duct to the adjacent wall structure is minimized while permitting maximum louver area and minimum marginal area.
Second, to provide a register of this character in which the louvers fit into a special frame so arranged that it may be adjusted to compensate for differences in lateral spacing between the hot air duct and the adjacent wall while effecting a seal between the hot air duct and a surrounding cooling jacket.
Third, to provide a novelly arranged and inherently attractive louver frame structure which incorporates an outwardly invisible louver retainer.
With the above and other objects in view, as may appear hereinafter, reference is directed to the accompanying drawings, in which:
Figure 1 is a front view of our register with the surrounding wall shown fragmentarily and with a portion of the register shown in section.
Figure 2 is a partial sectional view through the wall adjacent the register with the register shown in elevation, the section being taken along the line 22 of Figure 1.
Figure 3 is a fragmentary transverse sectional view through line 33 of Figure 1.
Figure 4 is a fragmentary sectional view through line 44 of Figure 1.
Figure 5 is a fragmentary sectional view through line 5--5 of Figure 4.
Figure 6 is a front View of our register for wall heaters showing a modified form for louver mounting.
Figure '7 is a sectional view thereof through 'Il of Figure 6.
Figure 8 is a fragmentary perspective view of the modified louver frame.
Our hot air register includes a hot air duct 1 which is adapted to be set within a wall structure. The lower end of the duct is open and communicates with a floor furnace (not shown). The duct I includes side walls 2 which traverse the wall structure in which the register is mounted. The upper extremities of the side walls 2 are connected by a top baiile 3 which is V-shaped in cross section.
A space is provided between the side walls 2 and the adjacent wall structure. In this space is positioned a vertical shield 4 comprising an inner plate 5 and an outer plate 6. The outer plate may lie contiguous to the wall studding S. The plates are joined .together at their lateral margins so that they define an air space. The upper extremities of the plates 5 and E are joined respectively to top plates or cross plates 1 and 8. In addition, a third top plate 9 may be provided. The top plates underlie a cross member 0 which forms part of the Wall structure and extends between the studding S.
The top shield plates l and 8 define an opening Iii directed laterally or outwardly from the wall structure in which the register is mounted.
The lower portions of the side walls 2 of the hot air duct are joined by cross plates II. The side walls 2, top baffle 3, and cross plates ll, of the duct, define the lateral openings directed into each of the rooms separated by the wall structure in which the register is mounted.
Each outlet opening from the hot air duct is covered by a louver frame l2 comprising a top member 13, side members or structures [4, and a bottom member l5. The side members or structures hi are substantially channel-shaped in cross section to form an outer or major flange is which is adapted to contact the plaster P or other material comprising the surface of the wall structure. The web of each side member [4 is provided with a shoulder I! so as to divide the web longitudinally into an extended face I8 and a recessed face it. The recessed face 19 is joined to an inner or minor flange 20 which is parallel with the outer flange l6 and is adapted to lit in contiguous confronting relation with the corresponding margin of a side wall 2 so as to seal the interior of the duct from the space between the duct and the wall structure.
The shoulders I! of each corresponding pair of side members it are provided with slots which receive louver plates 2|. The louvers extend across the opening to the hot air conduit and in front of the recessed faces l9 so that these faces are concealed by the louvers.
The extremities of the louvers 2! are hidden within the side members l4 between the shoulders l1 and the outer flange It. The louvers are yieldably held in place by means of spring plates 22 secured to the inner flanges 20 and projecting therefrom so as to overlie and bear against the extremities of the louvers.
It is preferred that the margins of the side walls 2 of the hot air duct diverge downwardly and outwardly from the wall structure and that the louver frames be arranged so that the outer flanges it increase in depth toward their lower ends. The lower portions of the outer flanges 16 are provided with cold air intake ports 23 which communicate with the space between the hot air conduit I and the wall structure. Such communication is facilitated by additional ports 24 provided in the shield plates and 5.
The thickness of the wall structure in which the heater is placed may vary materially. This may be due to differences in the dimensions of the studding or the differences in the thickness of the plaster which covers the wall structure. It is desirable, however, that the outer flanges of the louver frame fit snugly against the wall so as to present a neat appearance. By reason of the fact that the inner flanges 2!} are in contiguous confronting relation with the side walls of the hot air duct the louver frames may be adjusted inwardly or outwardly into conformity with the wall surface without creating an opening between the hot air duct and the space between this duct and surrounding wall structure. This is important for the reason that an opening of any magnitude at the margin of the hot air duct would permit an undesirable large quantity of hot air to flow into the space between the duct and the surrounding wall structure and thereby unduly heat the wall structure.
Reference is now directed to the modified construction shown in Figures 6, 7 and 8. This construction differs over the previously described construction in that the shoulders ii are not slotted and the louvers are mounted on an inner or subframe. Such subframe includes vertical angle members or side strips 3| which are adapted to overlie the recessed faces 9. The modified louvers 32 extend between the side members 3! and are cut and bent at their upper corners to form tabs 33 adapted to overlie the side members or strips 3| and be spotwelded or otherwise secured thereto. It can be seen that the side members 3i and louvers, form a unitary structure which may be set into the space between the shoulders I I. In order to retain the louver struc ture in place, the upper extremities of the side members 3! may project through the top member [13 of the louver frame as shown in Figure 6.
It will be observed that the sealing arrangement between the louver frame and the margins of the hot air duct is accomplished without requiring louver frame side members which have the appearance of being excessively wide.
It will be observed that the louvers extend in front of a portion of the side frame so that the side member appears to be relatively narrow.
It will be observed that the spring plates 22 provide a simple, yet effective, means of holding the louvers in place against accidental dislodgement but permit their removal at any time, should this be desired. For example, the recessed face [8 may receive attachment screws which are hidden by the louvers but are rendered accessible by means of the removable arrangement of the louvers.
It should also be observed that heretofore it has been difficult or impractical to so incline the louvers as to make them sight proof from normal viewing angles for such inclination (essentially the inclination shown) is virtually at right angles to the air stream tending to issue from the air duct; consequently, the air on impinging on the flat inner face of the louver tends to fiow laterally. Such lateral flow into the space between the air duct and wall structure is pre- 4 vented by our arrangement without introduc tion of other undesirable features.
Having fully described our invention, it is to be understood that we do not wish to be limited to the details herein set forth, but our invention is of the full scope of the appended claims.
