DOUBLE-HUNG WINDOW SASH.

Application filed FebruaryA 7, 1927. Serial No. 166,562.

This invention relates to window constructions. g

The object of the invention is to provide double hung window sashes with pivoted glass sashes constructed and arranged to be swung upon the pivots to permit cleaning the outside of a window from the inside of a dwelling.

Another object of the invention resides in the provision of a window glass sash swingingly mounted in a sliding window sash, the sashes having grooves adapted to register, into and out of which may slidably move a combined locking and sealing plate whereby to fasten the swinging sash against swinging movement and to exclude air from the room, and whereby the combined fastening and air sealing device may be moved to permit swinging movement of the swinging sash.

lVith the above and other objects in view, the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor detailsvof construction, within the scope of the claim, may be.

resorted to without departing from the spirit or sacricing any of the advantages of the'invention.

In the drawings:

Figure 1 is a front elevation of a window construction embodying a window frame and upper and lower sliding sashes, in each of which is pivoted a glass'sash.

Fig. 2 is an enlarged detailed longitudinal sectional view.

Fig. 3 is an enlarged detailed cross sectional view.

Fig. 4 is a detail view of the combined locking and air excluding means for the swinging sashes.

Referring now lmore particularly to the accompanying drawings, the reference character 5 indicates a window frame in which the upper and lower sashes 6 and 7 are slidably mounted in the usual manner and provided with the usual sash balances (not shown). Each sliding sash has a groove 8 9 in the inner faces of its opposite sides for a purpose presently understood.

A glass swinging sash 10 is swingingly mounted in each sliding sash, and at each side each glass sash 10 is provided in its outer face with a longitudinal groove -ll fectedin any suitable manner.

adapted to normally register with the respective grooves 8-9 of the respective sliding sashes 6 and 7. The swinging or pivotal mounting of the glass sashes 10`may be et- One way ot accomplishing this is to provide each glass sash 10 with suitablepivots on opposite sides thereof for engagement in the channel bearing sockets 13 of the upper and lower sashes 6 and 7.

A suitable device for locking the swinging glass sashes against swinging movement and to exclude air, is provided, there being a pair of devices for this purpose associated with each of the upper and lower window sashes. In the drawings there is a locking plate 14 adapted normally to cover the joint at each side of each of the upper and lower windows, the plate 14 lying in the respective grooves of the sliding and swinging sashes and being disposed over the joint to lock the swinging sashes against movement and eX- clude air at the sides of the sashes. Each plate 111 has a lateral projection 15 which extends into a recess 16 in the side of the respective sliding sash, and along its lower edge each projection 15 is provided with gear teeth 16a. A pinion 17 is mounted in each side of each sliding sash on a shaft 18 which has its outer end journalled in a bracket 19 on the respective sliding sash and projecting through the bracket sufiiciently to permit the application of a suitable tool (not shown) for rotating the pinion 17.

By rotating the respective pinions 17 in one direction it will be understood that the plates 14 will be withdrawn from the respective grooves in the sides of the swinging glass sashes beyond the side joints between the latter and the sliding sashes, so as to permit swinging movement of the sashes on their pivots 12. `Upon bringing the swinging sashes into closed relation with the sliding sashes, the rotating of the pinions in the opposite directions effects locking of the swinging sashes against swinging movement and also prevents air passing between the sides of the swinging and sliding sashes. The plates 14 are of a length substantially the length of the swinging sashes.

From the foregoing it will be seen that I provide a window construction wherein the usual sliding sashes carry swinging glass sashes so as to permit the cleaning of the outside of the glass from the inside of the dwelling, and that the swinging glass sashes may be held in locked position oy a device which effects not only the lockingbut serves as an airy sealing device at the sides of the a longitudinal groove inthe inner face ofv each side, a glass sash pivoted in each sliding sash andv eachirprovidedwith alongivtudinal'groove inthe outer face of each side to align with the respective'grooves of the respective sliding sashes', a plate mounted in the aligning grooves of thel sliding and swinging ,slashes at web Sid@ Qf the latter and each plate having an integral, flat lateral projection intermediate its ends eXtendyplates out ofthe respective grooves of the swinging glass sashes to permit swinging movement of the' latter, the'pivotso' the g'ass sashes being spaced from' the plates and their projections. i 'A i 1n testimony whereof have hereunto set my' ihand.

JQHN eOUGH.
