2 Claims. 1

The present invention relates generally to improvements in the art of ventilation, and relates more particularly to improvements in the construction and operation of storm sash ventilators.

It has heretofore been common practice to provide ventilators associated with storm sash of buildings for permitting a moderate supply of fresh air to the building interior without necessity of opening the storm windows; to which the ventilators were applied. These prior storm sash Ventilators usually consisted of one or more holes bored or otherwise formed through the lower rail of each sash, and a closure plate of wood, metal, or the like for the hole or holes attached to theinner side ofthe rail in a manner such as to permit movement to various positions for covering or uncovering the holes to varied extents. In such prior art ventilators, however, it was always deemed advantageous to form the adjustable closure plate in a manner such as to provide the tightest and closest possible fit, particularly when in closed position; and one commercially successful type of storm sash ventilator in prior use is shown and described in Patent No. 2,101,941, dated December 14, 1937, to William C. Hansen andHenry J. Goelzer. However, these prior close-fitting ventilating devices have proven somewhat objectionable in that circulation of air adjacent the glass pane was eliminated and humidity within the room was usually lowered when the tight-fitting closure plate was in closed position, thereby resulting in formation of condensation and front on the pane; and furthermore since the customary closure plates were movable upwardly to open the vent holes, the air circulated by these openings could notbe properly directed and uniformly distributed to effectively prevent formation of condensation or frost without opening the closure plates to the fullest, extent.

It is therefore a primary object of my present invention to provide an improved storm sash ventilating assemblage which is simple in construction, and eihcient in operation, and which obviates the objectionable features and disadvantages of the prior ventilators.

A more specific object of my invention is to provide an improved storm sash ventilating assemblage wherein a limited amount of air is constantly directed and circulated, as in spaced jets, uniformly across the inner surface of the stormwindow pane, thereby tending to equalize the temperature on both innerand outer surfaces of the pane and minimizing. the possibility of condensation and frost formation.

- 2 Another specific objectof this inventionis. to provide an improved storm sash ventilator which may be readily. manufactured of sheet metal or the like with the aid. of punches and dies, and which may also be readily applied and utilized:

by a novice without need of special equipment.

An additional specific object of the invention is to provide an improved storm sash ventilating assemblage-of the type having-one or moreslots or openings adapted to be covered by an adjustable plate, the plate being provided witha series of spaced channels or forming passages from the slots the interior of the storm window. I

A further specific object of the present invenor openings to tion is to provide an improved ventilatinga-ssem-;

blage which may be quickly and easily installed on existing storm sash, which may be manufactured and sold at moderate cost, and which is durable in construction and attractive in appearance.

Still another specific object of the present invention is to provide an improved ventilating device of the type having an elongated adjustable cover plate adaptedto snugly engage the- These and other specific objects and advantages of the present improvement will be apparent from the following detailed description.

A clear conception of the, invention, and of the mode of constructing, applying, and utilizing the improved had by referring to, the drawing accompanying and forming a part of this specification, wherein like reference characters designate the same or.

similar parts in theseveral views.

Fig. 1 is an inside view of a fragment of a typical storm sash with one of my improved ventilators applied thereto, the ventilator cover plate being shown in completelyv closed position by means of full lines and in by. means of dot-and-dash lines;v

Fig. 2 is a longitudinal horizontal section through the window or the line 2-2 of Fig. 1;

Fig. 3 is a transverse vertical section through the storm sash and ventilator assemblage, taken along the line 3-3 of Fig. 1;

Fig. 4 is a somewhat reduced fragmentary inpartially open position grooves directed upwardly along the sash engaging surface thereof and ventilating assemblage, may be;

Fig. 5 is a longitudinal horizontal section through the sash rail of the modified assemblage of Fig. 4, taken along the line 5-5.

While the invention has been shown and described herein as being embodied in a storm sash ventilator wherein the lower sash rail is provided with a series of circular holes adapted to be covered to varied extents by a sheet metal closure plate of a particular design, it is not my desire or intent to thereby unnecessarily restrict or limit the scope or utility of the improvement, since the ventilating appliance may obviously be associated with other types of closures and may be formed of other materials.

Referring to the drawing, the improved ventilator is shown therein as applied to a storm sash or window of usual construction having a lower rail 8 provided with either a horizontal air admission slot or a series of air admission holes 9 formed therethrough and associated with a transparent window pane ID.

The improved ventilating assemblage shown particularly in Figs. 1 to 3 comprises, in general, an elongated closure or cover plate II of sufficient size to cover the slot or all of the air admission holes 9 and being pivotally secured at an end thereof to the bottom rail 8 as at I2 with a hook shaped projection I3 at the opposite end adapted to coast with a stop pin I4 or the like on the bottom rail 8 to definitely locate the cover I I in closed horizontal position when swung counterclockwise about the pivot I2; and the cover plate II is dished and is formed with a stepped flange or ridge I5 about the marginal edge thereof to provide rigidity and snug seating engagement with the inner surface of the rail 8, the flange I5 i,

being provided along the upper sash engaging portion thereof with a series of spaced, upwardly directed channels or grooves I6 forming passages from the slot or each of the air admission holes 9 to the interior of the sash and toward the pane I0 thereof.

The cover plate II may obviously be formed of sheet metal with the aid of punches and dies, or it may be formed of Wood, molded plastic or other non-metallic material as desired. This cover plate II may also be made in various shapes, and may be readily provided with a socket H of any desired shape and size adjacent the swinging end thereof to provide a convenient finger-receiving means for facilitating manipulation of the cover I I about the pivot I2 in an obvious manner to open and closed position. The plate I I may also be attractively decorated as by providing any number of spaced ribs I8 on the face thereof, and when these ribs I8 are formed longitudinally of the plate i I, they aid in strengthening and reinforcing the shallow U-shaped plate member. Any ordinary screw or bolt may be used for the pivot I2 as well as the stop I4; and while any desired number of the channels or grooves I6 may be provided in the upper portion of the marginal flange I5, it is de sirable to space these channels a more or less uniform distance apart to obtain a more even distribution of 'air over the glass pane I0, and when a series of holes 9 are provided, as shown, instead of a single elongated slot for air admission, it is preferable to provide a channel I6 for each of the holes 9.

The modified assemblage shown in Figs. 4 and 5 is substantially like that hereinabove described with reference to Figs. 1 to 3 with the exception of the limit stop means for the closure or cover. Referring to Figs. 4 and 5, the ventilating assem blage shown therein comprises, in general, an elongated cover member I I for the air admission slot or holes 9 pivotally secured at one end to the inner surface of the bottom rail 8 and having the free end I3 thereof inclined with respect to its top and bottom edges so that the top edge is longer than the bottom edge, and a stop member I4 fixedly secured to the bottom rail 8' in any suitable manner and having a similarly inclined flanged portion arranged to engage and overlap the inclined free edge of the cover plate I I so as to arrest downward movement of the cover plate when the same is lowered about its pivot in a counterclockwise direction. The cover plate II of the modified device is likewise dished to a shallow U-shape and is formed with a stepped flange I5 about the marginal edge thereof to provide rigidity and snug engagement with the rail 8', and the flange I5 is provided along the upper sash-engaging portion thereof with a similar series of spaced-apart, upwardly directed channels or grooves I6 forming passages from each of the holes 9' to the interior of the sash and toward the pane thereof.

As shown, the stop member I4 may be positioned so as to partly overlap the end hole 9' to save material, and the inclined flanged edge thereof may be curved outwardly at the upper portion thereof to provide one of the channels I6. The parts of the modified assemblage may likewise be formed of metal, wood, plastic or the like, and may assume any desired shapes. A finger-manipulating socket I'I' may also be preferably formed in the cover plate II, and the plate II as well as the stop member I4 may be decorated with ribs I8 or the like which add rigidity thereto. The stop member I4 may be fixedly attached to the rail 8 in an obvious manner by screws or the like, and a screw or bolt may form the pivot for the plate II as shown with reference to Figs. 1 and 2.

In actual use of the improved device, the cover plate II, II is first applied to the sash rail 8, 8' by means of the pivot pin or screw I2 for sliding cooperation therewith about the pivot and the stop member I4, I4 is then likewise secured to the sash rail in proper position so that the

openings

9, 9 are concealed when the cover is in its normal horizontal position as shown by full lines in the drawing. The marginal flange I5, I5 of the U-shaped cover II, II is then maintained in snug engagement with the inner surface of the rail 8, 8' except at the local upper portions where the channels or grooves I6, I6 are formed; and whether the cover plate is. in fully closed position or in partially open position, these channels or grooves form passages at the upper edge of the cover to direct a limited amount of air in the form of jets uniformly from the

air admission holes

9, 9 upwardly toward and across the inner surface of the pane ID, thereby tending to equalize the temperature on the inner and outer surfaces of the pane to minimize the possibility of condensation or frost formation and likewise tending to raise the humidity within the enclosure. The air seepage through the channels I6, I6 is so directed and controlled in limited quantities that the effects thereof on the insulation value of the storm sash are not appreciable, but the benefits derived from elimination of condensation and frost formation are highly desirable. If it is desired to admit a greater amount of fresh air to the enclosure without opening the storm sash, the cover plate H, H may be conveniently and quickly raised in a clockwise direction about its pivot, as shown by means of dotand-dash lines in Fig. 1, upon insertion of one or more fingers in the socket I1, I'! and manipulation thereof in an obvious manner to any desired position.

From the foregoing detailed description, it will be apparent that my present invention contemplates provision of an improved storm sash ventilating assemblage which is exceedingly simple, compact, and durable in construction, and which is moreover highly efficient and flexible in use. The devices may be produced in a rapid manner from sheet metal, wood, plastic, or the like, and may be readily installed on existing storm sash or on new sash at extremely low cost and with the aid of standard tools. The cover plate II, II as well as the stop member l4, l4 may be attractively decorated with ribs I8, I 8' or the like which also serve to strengthen and add rigidity thereto, and these devices may obviously be applied to and utilized with any standard storm sash having either a single elongated air vent slot or a series of spaced vent holes 9, 9' as shown. Undesirable uncontrolled air drafts and seepage is minimized by the flange or shoulder 15, I which snugly engages the inner surface of the rail 8, 8' about the air admission holes, and undesirable condensation and frost formation is minimized and proper humidity maintenance is aided by reason of the spaced channels I6, 16'.

It should be understood that it is not desired or intended to limit this invention to the exact details of construction, or to the precise mode of use, herein shown and described, for various modifications within the scope of the appended claims may occur to persons skilled in the art to which this invention pertains.

I claim:
