UR PH Y IN w MJM United States Patent DIRECT STORM WINDOW VENT CONTROL William M. Murphy, Cleveland, Qhio Application July 5, 1955, Serial No. 520,052

Claims. (Cl. 98-97) This invention relates to storm sash and primarily to novel means for regulating ventilation where storm sash are in place, without moving theentire sash.

More particularly the invention provides a novel, inexpensive, vent control device, which is readily attachable to storm sash and includes means for controlling the device, operable by the usual window sash.

It is therefore a principal object of this invention to provide a vent control device formed of simple elements, easily installed and readily operable without complicated mechanical connections, the operation being effected by manipulation of the usual window sash in response to opening and closing movement thereof.

A further object of the invention is to provide a device of the class described, which includes a mounting member, a closure member hinged thereto, an arm extending from the closure member for controlling opening and closing movements thereof, and resilient means normally biasing the closure member toward open position.

Yet another object of the invention is to provide a 'vent control unit or device which may be provided as a unit readily attachable to a storm sash or the like so as to regulate air flow into a room which is provided therewith, there being no necessity for moving the entire sash for this purpose.

Other and further objects of the invention will be understood from a consideration of the specification appended hereto and shown in the drawing wherein:

Figure 1 is a sectional view showing a vent control unit formed in accordance with this. invention, emplaced on a storm sash and fragmentary sections of the storm sash and usual window sash and sill being illustrated.

Figure 2 is a plan view of a vent control unit according to this invention.

Figure 3 is a perspective view of the said unit.

Figure 4 is a fragmentary sectional view taken about on the line 44 of Figure 2 looking in the direction of the arrows.

Referring now to the drawing, the vent control unit of this invention is shown as being comprised of a mounting member 1 of relatively long narrow configuration having the mounting holes 2 therein. The mounting member 1 may preferably be formed of relatively .thin metal mat-erial and at its ends and depending therefrom are the rolled sections 3, which are each so formed as to constitute a portion of a hinge. The mounting member 1 is further equipped at its upper edge with an extension 4 to which may be fastened a spring 5 as will be subsequently explained.

Below or at the opposite edge of the part 1, is a further extension 6 which constitutes a stop, the same being formed at an angle to regulate the operation of other parts as will be readily understood hereinafter.

A closure member 7 is provided, and while this may be of any preferred length and width, it will usually be of fairly long narrow configuration substantially rectangular in outline and likewise formed of relatively thin metall material preferably. At its upper edge as seen in Figure 2, the said closure member 7 is provided with the rolled sections 8, each constituting portions of a hinge so that in conjunction with a portion 3 a completehinge is provided. Of course it will be necessary to provide suitable pintles 9, so as to maintain the parts 3 and 8 in op* erating connection.

Offstanding from the central portion of the closure member 7 is the control or operating arm 10 best seen in Figures 1 and 3, said arm being preferably of rod mate-- rial and formed at one end with a right angular extending portion 11 which may be flattened at one side so as to seat against the face of the closure member 7 and be fastened in place as by means of the rivets 1 2 entering through suitable openings in both of the parts and set in the usual manner.

It will be seen particularly clearly in Figure 1, the end portion of the arm 10 is bent or formed at about a '45 degree angle, this portion being denoted 13. Atthe extremity of the portion 13 and best seen in Figure 2, the arm 101's bent at right angles at 15 to .the portion 13 and also to the main part of the arm 10, so as to receive thereon a roller 16 which is preferably formed of rubber or similar resilient material. In order to maintain the roller in place on the portion 15 of the arm 10, a suitable washer 17 and cotter pin 18 may be provided, the cotter pin 1-8 obviously being entered in a suitably formed opening at the extreme end portion of the part 15.-

At this point the Figure 4 fragmentary view is referred to, which in conjunction with Figure 1 illustrates the manner of formation of the portion 15 of the arm 10, as being flattened either by grinding or in some other manner at 20, this flattened portion extending along the portion 15 for purposes which will be subsequently explained.

The spring 5 previously referred to, is connected as illustrated in the drawings at one end at 21 to the portion 4 and at the other end provided with a loop 22 which is of sufiicien't size to receive therethrough .the arm 10 and be able to move along the arm during operation of the device as a whole as will be now set forth.

The device or vent unit herein just explained, may preferably be mounted as by means of the screws 24 on a storm sash bottom rail "25, so as to place the closure member 7 in position to close the openings 26 which are drilled in any preferred manner in the rail 25. The usual sill 27 is shown in the drawing, and at the inner section of the sill in the usual location and shown in fragmentary section is the usual window sash 28 which is manipulatable upwardly and downwardly as is well known.

It will be apparent that the operating arm 10 is so proportioned as to extend to the position shown in dotted lines in Figure 1, when the window sash 28 is moved into the dotted line position therefore shown in that view, to move downwardly against the roller and obviously cause the closure member to move in a clockwise direction and into position against the inner face 30 of the storm sash rail 25 and thus cover completely the openings 26 therein. I

Since the roller 16 is resilient to a certain extent, this will accommodate some variation in the spacing between the sash 28 and the sash rail 25 as will be apparent, but it should also be noted that the flattened section 20 will permit the roller 16 to flow somewhat and thus accommodate for even greater variation in the spacing of the respective sash members.

Another feature which is pointed out is that residing in the arrangement of the spring 5 which will move at its end 22 along the arm 1-0 during changing of the angular relationship of the arm and upon raising or lowering movement of the sash 28. This will, therefore, cause the spring 5 to have generally uniform tension during its operating movement.

As will be understood from the foregoing description, any number of openings 26 may be formed in the lower rail 25 of a storm sash, and obviously the member 27 may be of any preferred length as will be true of the mounting means member 1. Thus a substantial amount of air may be admitted or the corresponding amount be excluded from entrance into a room, the vent unit obviously being operated to open position only when the usual sash is raised to obtain the ventilation desired. -It will also be seen that a novel form of the mounting member 1 which includes not only a stop to regulate the opening movement possible by the closure member 7 also includes a spring hanger so to speak to which the spring may be attached.

As a whole the unit hereof may be sold as a unit and readily attached by any person whether skilled or otherwise so that a novel device is provided making possible vent control for storm sash.

While certain shapes of parts and types of material have been described as being preferred, it is apparent that others may be suitable. In particular reference is made to the operating or .control arm which may be of flat or resilient material and yet perform the same function, the shape being likewise suitably modified so long as the operating characteristics are retained.
