RADIATOR HOOD Filed July 18. 1927 2 Sheets-Sheet 1 Patented Nov. 5, 1929 UNITED STATES PATENT fil lfihi WILLIAM S. ELTERS, OF DAYTON, OHIO, ASSIGNOB IQ THE GEM METAL SHIELD, INC., 0 DAYTON, OHIO, A CDRPOBATION Q]? OHIO RADIATOR H001) Application filed July 18,

This invention relates to ventilating apparatus and more particularly to an adjustable hood or cowl for steam and hot water radiators for diverting and directing the air currents arising therefrom.

In the present invention there is contemplated a radiator hood or cowl comprising two telescopically adjustable sections arranged in overlapping slidable relation. Each of the sections embodies an end wall, a rear wall or skirt, and a top portion. The forward marginal edges of the top portion of the separate sections are turned or rolled upon themselves into semi-tubular form with the inturned margin of one section enclosed in and slidingly adjustable within that of the other section. The lower portions of the rear skirts of such sections are formed with interlocking plaits or folds. The plait or fold of one slidingly engages in that of the other. The interlocked portions .of the rear walls extend downwardly and rearwardly to ailord an angular extension to engage a wall in the rear of a radiator and so prevent the passage of air currents between the wall of the room and the rear wall or skirt portion of the hood or cowl.

In addition to these features there are provided on the under side of the top portion of the relatively adjustable sections spacer members adapted to rest upon the top of the radiator and so elevate the hood or cowl a limited distance thereabove. One of such spacers is provided on the under side of the top portion and adjacent to the end wall of each section while an adjustable s acer is provided adjacent the inner end 0 one of the overlapping sections on which itis independently slidably adjustable to medially support the top of the hood or cowl. These supports or spacer members are so arranged and attached as to permit the ends of the relatively adjustable telescopic sections to pass into overlapping relation when the hood or cowl is contracted to minimum length. In addition to these features, the end walls of the respective sections are provided with inwardly spaced or offset fingers which are adapted to contact the ends of the radiator and so maintain the end walls in 1927. Serial No. 206,539.

predetermined spaced relation with the ends of the radiator structure. Attachments for securing the hood or cowl to the radiator are adjustably connected to such spacer lingers by adjusting bolts or links which serve to securely clamp the hood or cowl in place upon the radiator.

The object of the invention is to simplify the structure as well as the means and mode of applying such hoods or cowls to steam or hot water radiators, or the like, whereby they will not only be cheapened in construction but will be more eiiicient in use and capable of being easily and quickly attached and detached, adjustable for radiators of diiie'rent sizes, and unlikely to get out of repair.

Such cowls or hoods of the present type are usually employed in residences, stores, office buildings, warehouses, and the like, for diverting and directin the air currents arising from steam and hot water radiators. As usually constructed such cowls or hoods are of integral construction, manufactured in predetermined sizes so that a dealer or manufacturer must carry in stock numerous hoods or cowls of different sizes to accommodate the various sizes of radiators to which they are to be applied, and which are not standardized. By the present construction the hood or cowl is adjustable to accommodate radiators of dillerent lengths, thereby materially reducing the quantity of the stock necessarily carried by the dealer or manu facturer. Furthermore the hood or cowl is so engageable with the radiator that it will not be easily displaced and will tend to hold such engagement under all conditions. The walls of the hood or cowl are held in spaced relation with the radiator structure, thereby insuring ample air spaces about the radiator within the hood or cowl and obstruction of the How of air about the radiator is avoided. By making the hood or cowl contractable as herein disclosed such hoods or cowls may be arranged in less space for storage and shi ment and may be conveniently and easily nested one within the other.

With the above primary and other incidental objects in view as will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, or their equivalents, as hereinafter described and set forth in the claims.

Referring to the accompanying drawing, wherein is shown the preferred, but not necessarily the only, form of embodiment of the invention, Fig. 1 is a perspective view of the adjustable hood or cowl applied to a conventional type of radiator. Fig. 2 is a transverse sectional view of the hood or cowl. Fig. 3 is a perspective view partly in section to illustrate the location and relation of the spacers or support. Fig. 4 is a rear view of the interlocked lower margins of the rear dependent portion of the hood. Fig. 5 is a detail sectional plan view illustrating the spacing fingers for the end walls and attachment hooks. Fig. 6 is a view similar to Fig. 3 showing the hood or cowl contracted and illustrating the overlapping relation of the end of the movable sectio and the spacer or support beneath the top of the hood. Fig. 7 is a detail view of a modification illustrating a different curvature of the end walls and top. Fig. 8 is a detail sectional view of a modification of the interlocking engagement-of the sections.

Like parts are indicated by similar characters of reference throughout the several views.

In the accompanying drawing 1 indicates a conventional type of steam or hot water radiator. The hood or cowl comprises two relatively adjust-able telescopic sections A and B. Each of these sections comprises an end wall 2 fixedly and rigidlyconnected with a rear dependent wall or skirt portion 3 and a top portion 4. The forward margins of the top portions 4 are turned or rolled downwardly and inwardly into substantially semi-tubular tions is slidingly extended within that of the other section. The expansive tendency of the rolled margin of one section opposing the contractive tendency of the rolled margin of the other section affords sufiicient frictional engagement to retain the respective sections A and B in their various positions of sliding adjustment. portions 3 of the respective sections overlap each other. The lower marginal edges of the rear or skirt portions 3 are inclined rearwardly. The margin of one section is bent to reverse position to enclose that of the other section. The overlapping inclined portions are thus maintained in close contact While permitting their longitudinal sliding engagement. To limit extension of the shield, the end of the overturned flange is formed into a hook tongue 6 which engages a stop plate 7 attached to the other section. Such interlocked inclined extensions may be bent to greater or leg degree of inclination The rolled margin of one of the sec The top 4 and rear skirtrear of the radiator 1.

By this means the space between the radiator and the wall is closed and all warm air currents arising in the rear of the radiator are deflectsforwardly beneath the hood or cowl and discharged from the front thereof. This prevents dust and dirt being carried upwardly in close proximity to the wall upon which it would find lodgement, giving to the wall a dirty unsightly appearance.

Located beneath the top portions 4 of the respective sections A and B and in close proximity to the end walls 2 are spacers or supports preferably formed from sheet metal. These spacers as illustrated are bent to chan nel shape, although obviously other forms of support or spacers may be employed. The spacer or support 8 attached to the outermost sectionA is loose along its inner margin 9 and also at its rear end adjacent to the de pendent skirt 3 to enable the end of the sliding section B to pass above and behind such spacer or support 8. The spacer or support 8 is therefore attached only along its outer margin adjacent to the end Wall 2 of the section A. The spacer or support 10 at the opposite end of the structure and carried by the innermost section B need not be loose on its inner margin 11 but may be secured at such margin to the telescopic section B. However, for simplicity of manufacture those supports 8 and 10 are ordinarily secured in the same manner by welding the outer sides to the end wall 2. In addition to these supports 8 and 10, a similar shaped support 12 is adgjustably secured to the inner sliding section adjacent to the overlapped end thereof.

The channel shaped supports are open at their forward and rearward ends and so do not interfere with free circulation of air. The medial adjustable support 12 is provided with terminal extensions 13 and 14. The extension 13 extends within and rests upon the inturned margins of the top portions at the front of the shield. The rearward extension 14 is downturned at its end as at 15 for engagement behind a cleat or guide strip 16 welded to the inside of the rear wall. This support 12 is slidingly adjustable upon the inturned front flanges and upon the guide strip 16, to enable it to be positioned at the central point when the telescopic sections are relatively adjusted.

These spacers or supports 8, 10 and 12 rest upon the top of the radiator 1 and hold the top of the hood or cowl in elevated relationto provide ample air space over the top of the radiators and beneath the top portions 4-4.

Secured to the inner sides of each of the end walls 2 is an offset spaced finger l7 projecting parallel with the end wall 2 but spaced inwardly therefrom. This finger 17 serves" proach of the end wall, thereby insuring an ample space intermediate the end wall 2 and th end of the radiator for circulation of air. The spacer finger 17 is also utilized for the attachment of a clamp hook 18. The end 19 of the finger 17 is perforated to receive a standard threaded stove bolt 20. The perforation in the transverse portion of the finger 17 is sufiiciently' close to the rearwardly extending portion of the finger to prevent the rotation of the nut 21 carried by the bolt 20. By this means the nut is held against rotation while the bolt is being adjusted to tighten the clamp hook 18 carried thereby which has operative engagement with the end of the radiator to secure the hood or cowl in place.

It is obviousthat if so desired the inclined deflector extension 7 may be omitted from the lower margins of the skirt portions 3 in which case the lower margin of the skirt 3 of the outer section A'will be upturned to afford a guide channel enclosing the lower portion of the skirt portion 3 of the inner section B. While the hood or cowl has been shown with a comparatively short skirt or rear dependent portion 3 it will be understood that this portion may be extended to any desired depth. Likewise the end walls 2 may be formed of any desired curvature of design to give to the hood or cowl an ornamental appearance. In lieu of a flat top surface 4 as illustrated in Figs. 1 and 2, this top portion may be given an upward inclination or substantially ogee form or other ornamental shape.

From the above description it will be apparent that there is thus provided a construction of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, and arrrangement of parts, without departing from the principle involved or sacrificing any of its advanages.

While in order to comply with the statute the invention is described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific details shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into effect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims.
