STORM-SASH FOR WINDOWS.

Specification of Letters Patent.

Patented Sept. 10, 1907.

Application iiled July 2, 1906. Serial No` 324,476.

To all 'whom it may concern:

Be it known that l, DAVIDSON TODD, ol the city olf Toronto, in the county ot York, in the Province ol Ontario, Canada, have invented certain new and useful Improvements in Storm-Sashes for Windows, ol which the lollowing is the specilication.

My invention relates to improvements in storm sashes l'or windows, and the object ol' the invention is to devise a simple form of storm sash applicable to the inside ol' the window, which will not interfere with the l'ree use ol the upper and lower sashes ol a window and will move with them, and yet which may be readily and quickly detached after winter use and it consists essentially ot' supplemental ripper and lower sashes, the lower supplemental sash being located adjacent to the ordinary lower sash and affixed thereto at the top, and the upper supplemental sash being located adjacent to the lower supplemental sash at the bottom and connected to the ordinary upper sash at the top by a detachable connection and to the lower supplemental sash at the bottom by a detachable connection as hereinafter more particularly explained.

Figure l, is a perspective view ol' a portion of a window casing showing my improved supplemental sashes, portion ol the sashes and casing being broken away to exhibit the construction. Fig. 2, is avertical section through the fasteners connecting the supplemental sashes to the ordinary sashes. Fig. 3, is a sectional plan.

ln the drawings like letters of reference indicate corresponding parts in each ligure.

A is the lintel and B the sill and C the sides ol a window casing or frame. y

D is an ordinary upper sash, which is held and has vertical movement between the strips D/ and D2.

E is the ordinary lower-sash, which has a beveled connection at the top to the upper sash, such as ordinarily provided.

F is the internal molding of the frame.

G is the lower supplemental sash, which is provided around the bottom and side edges with the weather strips Gf set in grooves in the edge of the sash as indicated.

G is weather strip located at the top of the supplemental sash G and extending to the upper supplemental sash H.

l is a plate ol' wood or metal secured to the top oi the ordinary sash E and supplemental sash G and bridging the same and extending from side to side ol the sash. The plate l serves to hold the weather strip G'2 in position.

I is a screw pin, which extends through the bottom rail ol` the sash G into the bottom rail ol the sash E.

The upper sash H is provided with a weather strip J, which extends around the top edge and two side edges ot' the same tting in grooves.

K are eyes extending through slots H at each side of the upper sash and also through plates H2 located to the inside of the slots. The eyes Hf are held in position by suitable thumb nuts H3. i l l 'l L are screw hooks, which are screwed into the ordinary upper sash D.

M are L-shaped bars provided with the upper bent end M and the lower bent end M2. The upper bent end M/ extends into a slot H4. The upper end of the bar M also extends through a bracket H5 and the lower end through a slotted plate H attached to the lower side of the supplemental sash H. There are two bars M one on each side of the sash. The lower bent end of each bar M extends into an undercut groove G3, which is provided at the top with a lateral enlargement G4 as indicated.

It will now be seen that the supplemental sashes G and H form storm sashes, which will elieetually prevent the ingress ol air in cold weather especially A1n view of the weather strips G and G2 and J, which are made ot felt or other suitable material.

lt will also be seen that from the connection ot the upper storm sash to the ordinary upper sash that they will move in unison, and the lower portion oi the storm sash will be held in position as it moves up and down by means ol the bars M at each side.

Should it be desired to disconnect the upper storm sash all that it will be necessary to do is to move the bar M upwardly in the slot H4 and necessarily in the slot G3 until the bent end M2 is opposite lthe lateral enlargement G4 when the bars M may be thrust laterally outwardly and pulled inwardly, thereby swinging the sash H outwardly. By pulling the sash H downwardly the sash D will also move downwardly, whereupon by swinging the sash H outwardly alter the top is below the top of the casing sullieiently the eyes K may be readily unhooked from the hooks L and the sash removed. -ln order to remove the lower sash now all that it will be necessary to do will be to disconnect the plate I and pins l/ thereon from the ordinary sash when the storm sash may be readily removed. Both sashes it will be readily understood may be replaced by reversing the operation of removal.

Each sash l preferably provid-e with lifting handles N and when the storm sashes are raised or lowered necessarily the outer sashes are also raised or lowered, so that air can be let into the room either from above or below, which is an important desideratum.

What l claim as my invention is:

il. ln storm sashes for windows, the combination with the ordinary top and lower sashes, of a storm sash provided with top and bottom and side weather strips, a top plate bridging the tops of the ordinary bottom sash and storm sash and secured to the same as and for the pui.

3. ln storm sashes for windows, the combination with Ithe upper sash, of a detachable storm sash located to the inside of the lower sash, and detachable means for connectine,l it to the upper sash, whereby they may move in unison as and for the purpose specified.
