WINDOW VENTILATION SHIELD.

Application filed January 6. 1922.

To all whom it may concern:

Be it known that I. THOMAS E. Lnwi's, a citizen of the United States, residing at Alliance. in the county of Stark and State of Ohio, have invented a new and useful lVin dow Ventilation Shield, of which the following is a specification.

This invention relates to improvements in window shields such as are placed in the lower portion of a window frame allowing the window to be opened to ventilate the room without permitting a direct draft upon the occupants of the room.

The objects of the invention are to provide a shield of this character which may be formed of sheet metal or the like and comprising two telescoping sections making the shield readily adaptable to windows of various widths, spring clamping means being -arried by the shield. for attaching the same to the window sill, the shield being so constructed that the sash may be lowered to any desired level beneath the top of the shield.

The above and other objects may be attained by providing a construction of window shield such as is illustrated in the ac conn anying drawing. in. which Figure l is a perspective view of a win dow shield embodying the invention;

Fig. 2, a cross sectional view through a portion of a window casing and sash showing a slightly modified form of shield mounted thereon; and

Fig. 3, a view similar to Fig. 2 showing a slightly modified form of clamping means.

Similar numerals of reference indicate -orresp(mding parts throughout the drawmg.

A portion of the window casing is illustrated at l, the sill at 3 and the sash at 3, all of which parts may be of any usual form. The shield which embodies the present invention may be formed of sheet metal,- the body portion of which comprises two telescoping sections -l and 5, the upper and lower edges of the section at being preferably folded back upon the body portion thereof to provide reinforced edges 6 which will be readily slidable within the channel grooves 7 provided at the upper and lower edges of the section Each section of the shield is provided at its outer end with a triangular wall 8. preferably reinforced at its edge with the folded portion 0. these triangular walls extending Serial N0. 527,320.

rearwardly, the rear edges thereof being vertical and parallel with. the sash.

hen placed in position upon the window, the lower edges of the sections 4 and 5 extend beneath the window sash as shown in Figs. 2 and 3, while the vertical edge of each triangular wall 8 is parallelwith the inner face of the sasl1,thus permitting the sash to be lowered into engagement with the lower end portion of the body of the shield.

For the purpose of securing the shield in place at the window, each section is provided with an inverted, V-shaped clamping member preferably formed of spring material and comprising the inclined leg 10 having the hooked end 11 for engagement with the outer edge of the sill and provided with the off-set portion 12 to accommodate the clamping link 13 which is located around the substantially vertical leg 14: provided at its lower end with the hooked portion 15 for engagement with the inner edge of the sill, a projection 16 being provided at the upper end of said hook comprising a rest to engage the top of the sill.

In F ig. 2 is shown a slightly modified forn'i of clamping device in which the leg 10 is provided with a greater off-set 12. thus reducing the angle between the legs of the clan'iping member in order that the link may more securely grip the same in clamped position. The remaining portions of the construction shown in Fig. 2 are the same as those above described.

In Fig. 3 a still further modification of the clamping device, in which the link is eliminated, is shown, the legs 10" and let" of the clamping device being connected at their upper extremities by the circular spring portion l7 designed to provide suflicient sprlng i in the clamp to cause the same to snugly engage opposite edges of the sill and hold the shield in position thereon.

The remaining portions of the device shown in Fig. 3, are similar to the construction illustrated in Fig. l and above described.

It will be evident that a shield is provided which may be readily adjusted to accommodate windows of various widths and which may be quickly and easily secured in place by clamping the same to the window sill, the device being so mnstructed that when socured in position upon a window, the shield does not form an obstruction to closing the sash, thus permitting of any desired amount of ventilation. Y

l. A Window shield comprising an 7 inclined body portion, triangular end Walls,

shield comprising a pair of hooked legs for engegen'ient with opposite edges or a W111- doW sill, and means for drawing said legs toward each other.

A Window shield comprising an inelined body portlon, triangular end Walls thereon and a clamping member upon the shield comln'ising apair of hooked legs for engzigenlent Withopposite QClgGSOl a window S111, and a link for drawing Sd-lCl. legs toward each other.
