WEATHER AND DUST PROOFING DEVICE.-

Specification of Letters Patent.

Patented Sept. 1, 1914.

Application filed November 29, 1912. Serial No. 734,064.

v To all whom it may concern Be it-known that I, JOHN B. GLowAoKI, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Weather and Dust Proofing Devices; and I do hereby declare that the followmg 1s a clear, and exact descriptlon of the reference being had to the accompanyand to the numbers of referwhich form a part of same, ing drawings, ence marked thereon, this specification.

' This invention relates more particularly to that class of weather and dust ,proofing devices adapted foruse in connection with windows, to seal the joint between the sasn and'the frame when the window is closed.= In such constructions usually the weather-- strip or weatherproofing device is rigidly secured to the frame to slidably engage the; sash or to the sash to slide upon the frame and in either construction a short pe iod of use usually occasions sufiiclent wear to render the device practically useless for the purpose for which intended It is an object of this invention to afi'ord upon the movable sash or the like, a weather proofing device movable relatively-thereto,- and impelled i'nto operative posit on by the closing of the window.

It is also an object of the invention to afford weatherproofin means carrled slidablyon the sides 0 the sash, and acting upon the closing of the sash to seal the joints between the sash and the frame at the sides thereof, and resilient weatherstrips carried 'at the ends of the sash to seal the joints between the same and the frame and, also between the sash. Other objects of the invention are set forth in the specification.- 5 o The invention '(in a preferred form) '18: illustratedin the drawings, and hereinaftermore fully described. f In the drawings: Figure 1 is an lnner front elevation ofa window frame with slidable sash therein, equlpped with weatherproof-- i'ng means embodying my invention. Fig. 2 is an enlarged fragmentary deta l view of the same. Fig. 3 is an enlarged section on line 3' of Fig. 1. Fig. 1 is an enlarged section-on line f Fig. 1. Fig. -5 is an enlarged section on line 5 of Fig. 1. F1g. 6 1s an enlarged section on line 6 of Fig. 1. F g. 7 is a fragmentary section on line 7 of F g.

3. Fig. 8 is a fragmentary section on line 8 of Fig. 7.

As shown in the drawings: 1, indicates the window frame as a whole, constructed as usual or in any preferred manner; that is to say, provided with the usual head jamb H and stop and side jambs and sill, and pro-* vided with parting strips 2, and stops 3. Between the blind stop 4, and parting strip 2, the upper sash 5 slldes as usual, and between said parting strip 2, and inner stop 3, the lower sash 6, is slidably supported. As shown, a parting rail or strip 7, having a thickness approximately equal to the thickness of the parting stop 2 is secured on the inner face of the lower ra' of the upper sash 5', provided with a downwardly inclined face to shed the water of condensation from the inner side of the upper sash downwardly, and Y to discharge between the same and the H lower sash, as shown in Fig. 6. The joint between said parting rail 7:, and the inner or lower sash, is closed by a res1l1ent Weatherstrip 8,; such as rubber,

which is engaged in place-by means of a strip 9, of sheet metal, the edge of whichis flanged over and inwardly around said resilient strip 8, to engage the same removably in place, and iniposition to bear upon the inner edge of said parting rail at the top thereof when both sashes are closed.

The upper sash is provided along its to rail with a resilient Weatherstrip, 10, whic bears against 'the head j amb of the window frame when the sash is closed, as shown in Fig. 4. This, as shown, is engaged in place by a formed strip 11, of metal, which is shaped to engage'on the outer and inner faces of the sash along the top thereof, and to afford a retaining seat for said strip,so that when the sash is closed the joint at the top of the sash and between the same and the head jamb is effectively sealed. As

shown "the retaining member 11, is inclined inwardly at the front edge to wedgingly engage between the parting strip 2, and the blind stop a. In a similar manner a resilient Weatherstrip 12, correspondin with the eatherstrip 10, before -descri ed, is 1 engaged in a suitable seat therefor ina sheet metal retaining stri 13, formed to engage along the outer and lnner faces of the lower sash along the bottom rail, as shown in Fig. 5, said retaining member being inclined toward said. resilient strip 12, at the lower edge to wedgingly engage the lower edgeof sashes and the frame when the sashes are closed. As shown, each of said weatherstrips comprises a metallic or other suitable strlp, having a straight edge adjacent the.

parting strip or stop, and provided with diagonally arranged parallel slots in each strip to receive the attaching screws or other means, whereby said strips are movably engaged upon the sash. Said movable weatherstrips 15, secured on the upper sash, are normally supported from engagement with the frame or stop by means of a spring 17, secured in a suitable casing 18. The lower end of said movable weatherstrips are cut away transversely at the lower ends from the inner edge to near the outer to afford a downwardly directed shoulder to bear upon said springs in said casings and, as shown an outwardly turned lip or projection 19, is provided on the upper end of eachof said movable weatherstr'ps adapted to impinge against a resilient (or other) projection 20, secured in the partingstrip, one at each side the sash and in position to be engaged by to a said outwardly turned flange or projection 19, when the upper sash is closed, and acting thereby to project said movable Weatherstrip downwardly and outwardly against the ten: sion of the springs.

The construction of the movable weatherstrips 16, for the lower sash, is identical with that before described, except that the casing 18, containing the springs 17, is secured at the upper rail of the lower sash and the outwardly turned lips 19, on said movable weatherstrip are engaged by rojections or buttons 20, secured on the su sill 14, or directly on said sill, as preferred, acting to project said movable weatherstrips upwardly and outwardly into engagement with the stop 3. Preferably the inner edge of the parting strip 2, and the inner edge of the stop 3, is slightly chamfered or cut away ord a recess to receive the bevel or thinned edge wedgingly thereinto when the sashes are closed, said movable weatherstrips thus serving not only to seal on said stops, but also acting to wedgingly engage between the sash and the said stops to force the sash outwardly and against the blind stop and the parting strip respectively,-thus sealing the oint both at the outer side and at the inner side of the sash.

Numerous details of the construction may be varied, and it is to be understood that I have shown but a preferred embodiment of y invention, and that,I do not purpose limiting the patent granted 'on this application otherwise than necessitated by the prior art.

I claim as my invention:

1. The combination with a window frame and a sliding sash movable between the stops thereon, of weather stripping mechanism comprising longitudinally movable Weatherstrip members mounted on the side rails ofthe sash, a slotted cylinder rigidly secured on said sash, a spring contained therein and normally bearing against one end of said movable member, pins securing said movable member engaging through inclined slots therein, and fixed in the window sash rail, and an outwardly turned projection on said movable member adapted to contact the frame when the sash is closed to project said movable member in wedging relation between the window sash and a stop against the compression of said spring to seal the sash in the window frame.

2. The combination with a window frame having a sash slidable between stops thereon, of weather stripping mechanism comprising a Weatherstrip member having inclined slots therein, pins engaging through said slots and into the window sash to movably connect said member and said sash together, a cylinder rigidlly secured on the window sash, and having s ots extending longitudinall thereof, a spring contained within said cy inder and normally bearing against one end of said member engaging in said slot in said cylinder, and means on the lower end of said member adapted to contact the window frame when the sash is closed to project said member between the sash and a stop against the stress of said spring to seal the sash in the window frame.

3. The combination with a window frame and a sash slidable therein, of weather stripping mechanism comprising a movable weather strip carried on the side of the sash adjacent the frame and having a beveled edge adapted to wedgingly engage between the sash and the frame, a projection "on said Weatherstrip adapted to engage a fixed part of the frame to project said strip outwardly into wedging engagement between the sash and the frame when the sash is closed, pins engaging through inclined slots in said weather stripping element to connect the same with said sash, said pin and slot connection causing adiagonal movement ofsaid Weatherstrip when. the same is moved relative the. sash, and a slotted cylinder secured on the sash with one end,

of said Weatherstrip slidably engaging therein permitting diagonal movement of said Weatherstrip element to take place in said -cylinder.

and lowersliding sashes, diagonally mov- 4. In a device of the class described upper,

able weather strips supported on each side no of each sash a rojection on each adapted to engage a e part adjacent thereto when the sash is closed to project the same outwardl to seal the joint between the sash and t e stops s rings engaging said mov-- 'able weather strips and acting to shift the same inwardly when the respective sashes are moved in opening, and slotted cylinders mounted on the meeting rail of each sash 10 to inclose said springs, the extremities of said weather strips engaging in said slots and guided in their movement thereby.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses. v
