This invention relates to windows and has for its primary object to provide for Ventilation when storm sash are used in conjuncton with casement windows of the type which open outwardly.

The conventional storm sash is usually provided with a plurality of openings which are ordinarily covered by a pivotally'mounted cover, and when ventilation is required the cover is moved to a position uncovering the openings. This is a simple matter when storm sash are used in conjunction with vertically slidable windows, but in the case of outwardly swinging casement Windows it is impossible to open them, due to interference by the storm sash, to an extent whereby a persons hand may be inserted to move the cover. To overcome this difiiculty the present invention provides means which functions automatically incident to opening movement of the casement window to move the cover member away from the openings in the sash.

Another object of the invention is to provide apparatus of the character above mentioned wherein the movement of the cover member is directly proportional to the movement of the casement window in order that the area of the ventilating openings may be varied at will.

With the above and other ends in View the invention is more fully disclosed with reference to the accompanying drawings, in which Figure 1 is a horizontal section;

Fig. 2 is a fragmental elevation of a storm sash;

Fig. 3 is a vertical section taken on the plane indicated by line 33 of Fig. 2;

Fig. 4 is a section taken on the plane indicated by the line 4-4 of Fig. 2, but illustrating the parts in a different position; v

Fig. 5 is a perspective view illustrating a slightly modified construction;

Fig. 6 is an elevation illustrating a modified cam bracket, and

Fig. 7 is a section thereof.

Like characters of reference are employed throughout the description and drawings to designate corresponding parts.

A casement window sash I is supported for swinging movement by a hinge 2, the direction of such swinging movement being toward a storm sash 3 which is supported in spaced relation to the sash I. In the lower portion of the sash 3 is a plurality of ventilating openings 4 and a pivoted cover member 5 adapted to cover the openings. The cover member 5 is formed of sheet metal and is pivoted at 6 whereby its free end engages a bracket 1 when it is positioned over the openings 4. A spring 55 has one end attached to the sash 3 and its other end connected to the cover member whereby it functions to normally hold the cover member over the openmgs.

Also mounted upon the pivot 6 is a rocking lever 8 having one end in engagement with a pin 9 carried by the cover member 5 and its other end in engagement with a plate Ill. That is, one end of the rocking lever 8 engages beneath the pin 9 on the cover member, and its other end engages beneath the plate Ill. The plate I0 is hingedly connected at H to a second plate I I2 which is pivotally connected at I3 to a bracket 14 mounted on the sash 3. The axis of the pivot I3 is parallel to the axis of the pivot 5.

Mounted on the sash l is a cam-like bracket l6 which is normally disposed adjacent to the plate I0. As the sash I is moved from the closed position shown in Fig. 3 to the partly opened shown in full lines in Fig. 2 to that shown in dotted lines. As the lever rocks, the plate E2 shifts about the pivot l3 and there is no binding action between the plate It and the rocking lever. When the sash I is restored to the position shown in Fig. 3 the spring l5 restores the cover member 4 to its normalposition.

It becomes apparent from the foregoing that the cover member is moved automatically incident to outward swinging movement of the sash l, and that the extent of movement of the cover member is proportional to the extent of movement of the sash i. may be partially or completely uncovered at the will of the operator.

In Fig. 5 there is shown a partly modified form of the invention. In this form the sash to has Openings 4a and a cover member 5a pivoted at 60. A rocking lever 8a is mounted on the pivot 6a with one end engaging a pin Go on the cover member and its other end engaging the underside of a plate la. The plate Ina is hingedly connected at Ila to a plate 211. The plate 12a, instead of being pivotally connected to the sash 3a as in the case of the plate I2, is rigidly connected to the sash 3a. It will be noted, however, that the plate l2a is mounted at such an angle that the axis of the hinge Ila; is at an angle to a horizontal plane.

When the cover member is moved from closed to open position the lever 8 rocks to such an Therefore, the openings extent that the angular position of the end engaging the plate lll or Illa changes materially. There is a tendency, due to this angularity, for the plate and lever to bind. This is overcome in one case by permitting the plate ID to shift with the rocking lever, and in the case of the plate Illa, by supporting the plate at a favorable angle.

In Figs. 6 and 7 there is illustrated a modified cam bracket composed of two parts, the cam portion 20 and the base portion 2|. The cam portion 30 is secured to the base portion by bolts 22 which extend through slots 23 in the base portion. This construction is designed to adapt the apparatus above described for installation in window structures wherein the distance between the casement window and the storm sash varies.

Although specific embodiments of the invention have been illustrated and described it will be understood that various changes may be made within the scope of the appended claims without departing from the spirit of the invention, and such changes are contemplated.
