WEATHER STRIP.

Application fled larch 15, 1926. .Serial No. seaao The invention relates to improvementsin weather strips designed for use upon 1nwardly swlnging casement windows and the v a movable strip is swun after described and claimed, the description being supplemented by the accompanying drawing. 1 Figure 1 is a perspective view of a casement window equipped with my invention. Figures 2 and 3 are vertical sectional views, partly in' elevation, showing the manner of operationof the movable strip.

Figure 4 is an additional sectional view out in a different plane from Figures 2 and 3 and showing the spring which constantly exerts a lifting force .on the movable strip, so as to raise'it to inoperative position'as soon as permitted to function in this manner.

Figure 5 is a perspectiveview of the device disconnected from the sash.

In the. drawing above brieflydescribed, 6 designates the sill of a) casement window and the numeral 7 designates two inwardly swinging sashes. A head 8, preferably formed from a' single metal plate, as shown, is secured upon the sill 6 and extends throughout the length thereof, and the lower 'edge of each sash 7 is rovided with a longitudinal recess 9 whic extends throughout the length of said edge and opens to the outer, side of the sash, but not through the inner side thereof, the sash beingformed with a groove 10 in the angle between the upper and-inner wallstof the recess 9.'

in Figures and 4 when the sash is closed. The strip isformed from a single elongated piece of sheet metal having one edge rolled to provide a tubular head 12, said bead having relatively small notches 13 near its ends and 'a r notch 14 between its ends. Bearings 15, preferably formed by bending metal strips at one end, positioned in the notches 13, while a coiled torsion spring 16 isdisposedinthenotchlL-Arodflpasses whi w ll exclude. may

any possibility the notches 13 and 14, said rod passing entirely through the tubular head 12 and through the bearings L5 and throu h the i 7 spring 16. An eye 18 at the angle 0 a bell crank 19, is positioned on one end of the rod 17 and is received in a notch 20 in one extremity of the tubular bead 12, one arm 21 of said bell crank being secured to the strip 11. while the other arm 22, is adapted for ooaction with the head 8 to swing said strip 11 downwardly against the action of the spring I 16, when the sash is closed;

When mounting the device in the recess f), the metal strips 23 from which the bearmgs 15 are bent, are secured by suitable fasteners 24 to the inner wall of said recess 9, the tubular head 12 and the parts located in its notches, then extending into the groove 10, so that the portion of the sash at the other side of this groove, forms a water shed, preventing any water from entering above the strip 11. When the device is so applied, one end 25 of the spring 16 bears against the lower side of the strip 11 and the otherfend 26 of said spring, engages the inner wallbf the recess-9. Thus, the spring has a constant tendency to raise the weather strip 11 to the horizontal position shown in Figure 2, in which position it will clear the head 8. When the strip is positioned in this manner the arm-22 projects downwardl so as to strike the bead 8 when the sas is closed, thereby swinging the bell crank 19 and moving-the strip 11 downwardly to the outwardly declined position-shown in Figures 3 and 4, in which position it: will efiectively prevent entrance of water, snow, sleet, wind, etc. As soon-as the sash is opened,

the pressure of the head 8 against the arm 22 is relieved, vallowing the spring 16 to swing the" strip 11 -upwardly, so that the sash may be easily opened.

Attention isinvitedto the fact that the bead 8 constitutes avstationary. weather stop A movable weather stripll is provided to outwardly ecline over the'bead 8 as shown means16tocomeintop y permits the spring for the purpose such of raisin the movable weather stop 11, clear of t e bead 8. Attention is also invited toithe fact that while the weather stop 11 and associated parts are preferably mounted in a recess such as 9, constituting a water shed, a shed of any other adequate form could be provided.

The invention is exceptionally simple and inexpensive yet will be efiicient and in every.

wa desirable. The results have been excel ent from the details disclosed and they are therefore preferably followed, but w1th-. in the scope of the invention as clalmed, variations may be made.

I claim; p i g 1. A weather seal adapted for mounting on acasement window sash for coaction' with an upstanding sill carried bead extending throughout the length of the sill and projecting above the sill to form a water stop, said seal comprising an elongated metal 7 strip having a tubular bead alon one of its is adapted to coaction with the sill-carried longitudinal edges, said bead belng formed near its ends'with notches, having another notch at one of its ends, and being formed with an. additional notch between its ends,

bearings in the notches near the ends of said bead having attaching means for anchorage to the sash, a coiled torsion spring in the notch between the ends of the bead, one end of said s ring engaging the strip while the other"end v sash, a rod passing loosely throught e en-- tire length of said tubular bead and spanning all of its notches, said rod passing throu h said bearings and said spring, and a bell crank having. an eye received-in" the notch at the end of said tubular bead, said eye being mounted on one extremity of. said rod, one arm of said bell crank being secured to said strip while the other arm thereof bead to offset lowering of the strip against the action of the aforesaid spring.

2. A weather seal for a'casement window sash, said sash having in its lower edge a longitudinal recess extending throughout the length of said edge and opening to the outer side of the sash and having a longitudinal groove in the anglle between the upper and inner walls of t e recess, said walls and groove forming a, water shed, said seal comthereof is adapted to enga e the,

prising an elongated sill-carriedbe'ad formed from a single strip of metal bent longitudinally 'upon it'self to form an upstanding portion and havin its opposite edge bent laterally to form, anges for attachment to the'sill, an- 'elongated sealing strip having a tubular bead along its upper longitudinal edge, said bead havinga plurality of notches, a rod passing throughv. said bead, bearing members arranged in certain of said notches secured to said strip while-the other arm thereof is adapted forco action with the.

sill carried bead to efl'ect the lowering of the sealing strip when the sash is closed.

- 3. An inwardly opening casement window sash having a water-shed throughout the width of its lower end, a weather stop ex-' tending longitudinally undersaid' water shed and piv ted to the sash for movement from an out ardly declined normal positron to, a raised inoperative position, a statlonary weather stop bead extending longitudinally of the window -sill, said head being normally disposed under the. upper portion of said. weather stop, spring meansacting on said weather stop and tending to raise it'clear of the bead, and an arm con nected with said wather'stop and normally .abutting the inner side of said bead to retam said weather stop in its-normal position against the action of said spring means, said ar m moving away from said bead and per mltting raising of said weather stop by said spring means as the sash is opened, said,

arm upon closing of the sash coming again into contact with the bead to again swing v the weather stop downwardly to operative whereof I have hereunto .affixedmy signature. v

position.

In testimony OWEN ,o. WATKINS.
