Application filed January 15, 1927. seriarmi. 161,328yi The present invention relates to a storm sash opcratingdevice. An object of the present invention is to operate a storm sash by means connected to a sliding sash with which it is associated to control the movements of the storm sash by a movement of said sli'dingsash.

In order to attain this object, there is provided, in accordancewith one feature of the invention, a link pivotally connected at one end to the sliding sash of a'window and hava slot therein which is in sliding engage ment with a pin connected to the window frame, and having a pin in the other end thereof mounted to ride in a slotted member connected to-thestorm sash.

These and other features of the invention, not specificaliy mentioned, will be more fully brought out in the following description and the accompanying drawings, wherein:

' Figure 1, is a View in vertical section through a window provided with the device showing the sash in closed positions in solid lines and in'open positions in dotted lines.

Figure 2, is a view in'perspective of'the device with the parts thereof in thepositions they would occupy when the sash were closed; and r Figure 3, is a sectional'view through the member by means of which the device is re-V movably connected to the sliding sash of the window. I

Referring to the drawings 1n detail, a window opening A 1s of conventional construc tion, with a sliding sash 1 mounted therein, a

storm sash 2 being hingedly connected to the top of the window opening in a well known manner. 'A plate 8 having a bent-up lug 4 in tegral therewith is provided with openings 5 by means of which the member may be secured to the sliding sash of a window by means of ordinary wood screws. A pin6 is permanently connected to the member 4 as by riveting and is provided with an annular groove 7 about the outer end thereof. A slotted arm 8 is mounted to pivot upon the pin 6, having a locking member 9 pivotally connected thereto as by means of a rivet 10, said member having a notch 11 in the lower side thereof to engage the annular groove 7 in the pin 6 and lock the slotted arm in position upon the pin. Ajsec;

0nd pin 12 is mounted to project'from the sideof the window frame as by means of screws 13,

The pin 12 is mounted'to ride in the slot 14 of the member 8 andis preferably somewhat, smaller than the slot- 1-1 to'fpermit a relative movement of the slotted member 8 with respect to the pin 12 before engagement therewith. Thiswill permit the sliding sash to be raiseda short distance'before the lower side of the slot 14-engages the pin 12. This feature is provided to permit the-insertion of a narrow instrument beneath the sash to drive the storm window open in case it should become frozen or otherwise stuck to the sill-or window opening. A pin'15'1sfixedly mounted upon the outer end of the slotted arm 8 to ride.

in the slot 16 of a slotted member 1.7 formed of a sheet of metal and having the bottomed through openings 19. The outer pin '15'- position, a slight relative movement is permitted between the slotted arm 8 and the pin 12, the second pin 15 riding upwardly in the slot 16 in the member 17 to permit the sliding sash to clear the inner sill'member before engaging the storm window to force it open as previously set forth. Upon the pin 12engaging the lower edge of'the slot 14 the arm 8 fulcrums upon the pin 12 and the storm window 2 is forced outwardly into an open position, the degree of opening being regulated innersliding' sash by the height to which the memberis raised.

- Upon the first engagement of the pin 12 by the lower edge of the slot 14;. it will be noted that the lever arm from the pin 6 tothe pin 12 is extremely long in comparison with the lever arm from the pin 12 to the upper pin 15 riding in the slot 16. This provides a powerful initial leverage for freeing the storm window from the frame and also in drawing it tightly into position upon closing the window. AS ,theslotted arm 8 rides upwardly past the pin 12 the relative lengths of the lever arms change so that while the initial opening'of the storm window is slight as compared with the movement of the sliding sash, the movement of the storm sash increases in proportion to the movement ofthe' sliding sash as the sliding sash is raised. The slotted member 17 is preferablymounted on sash and having: positive en the storm sash so that the bottom of the slot 16 therein will be slightly lower than the pin] 15 in the side of the window frame. This is done so that the slotted arm 8 will have a slight slope downwardly toward the storm sash when the parts are in fully open position as indicated in dotted lines. This firmly locks the storm window against movement inwardly until the sliding sash is lowered, since pressure on the storm window itself as in a strong wind would tend to force the storm sash inwardly. This would tend to force the arm 8 in clockwise direction, but, since the pin 15 is resting upon the bottom of the slot 16, such movement is prevented and the storm sash is rigidly locked in the open position.

Applicant is aware that devices have been made to operate storm sash in conjunction with the sliding sash of a window, but none of these structures so far as applicant is aware provides a positive means of actuation of the storm sash for both upward and downward movement of the slidin sash b means of a rigid, non-flexible member connecting the gagement with means connected to the window frame for both upward and downward movement of the sliding sash.

To remove the storm sash the locking member 9 may be moved upward about its pivot 10, freeing the notch 11 from the slot 7 and permitting the arm 8 to be withdrawn from the pin 6.

I claim:

1. In combination with a slidable window sash and a storm sash, a rigid actuating arm having a slot longitudinally thereof, said arm being pivoted to the window sash, means mounted upon the window frame to ride in said slot, a slotted memberfastened to the storm sash tohave the slot thereof positioned vertically, and means connecting the outer end of said arm to saidsecond slotted member to permitslidable movement of the outer end of said arm with respect to said slot.

tical track therein to receive theouter end of said actuating arm, the actuating arm being normally arranged to lie substantially ver- ,tically vith the major portion thereof below the means connected to the. window frame to draw the storm sash toa closed position and being slidable upwardly upon opening the sash to move the arm slidably over said means connected'to said window frame to move the arm to a substantially horizontal position with the major portion thereof exteriorly of said means to open. said storm sash.

in combination with a slidaole window sash and a hinged storm sash, an actuating arm pivotally connected to the slidable sash,

means connected to the window frame to slidably engage said actuatingarm, to prevent lateral movement of said actuating arm, with 1 respect to said guide means, and a traclrmember fastened to the storm sash to receive the outer end of said actuating arm, the actuating arm beingnormally arranged to lie substantially vertically with the major portion thereof below theguide meanswhen the slidable sash is closed to draw the stormj sash to a closed position, and being slidable upwardly =pon opening the slidable sash to move'the arm slidably upward over said guide means to move the arm to a substantially horizontal position with tie major portion thereof ere terio-rly of said guide iitieans to open said storm sash, said outer'end moving freely in said track member during the outward move: ment said actuating arm past said guide means. i

In testimony whereof I afiix my saiiumrn. THOMPSON.
