v WEATHER-STRIP.

. ipeciflcation of Letters Patent. Patented Apr. 20,1920.

Application filed March 20,-1917. Serial No. 155,981.

at Troy, in the county of Miami and State of Ohio, have invented certain new and useful Improvements in Weather-Strips, of which the following is a specification.

My invention relates to swinging sashes,

swinging doors or other closures, and more particularly to automobile .wind shields, and especially to a weather strip or sealing strip for effectively'closing the intervening crevice between the sash door or wind shield, and its support or the frame of the window or other opening.

The object. of the invention is to simplify the structure as well as the means and mode of operation of such devices whereby they will not only be cheapened in construction, but will be more efficient in use, positive and uniform in operation, and unlikely to get out of repair. I

A further object of the invention is to provide a form of overlapping jointwhich will obviate any crevice and compensate for any lack of uniformity of the engagement of the parts.

With the above primary and other incidental objects in view as will more fully appear in the specification, the invention consists of the features of construction, the

parts and combinations thereof, and the mode of operation, or their equivalents, as hereinafter described and set .forth in the claims. p

In the preferred embodiment of the invention illustrated in the drawing, Figure portion of a sash or wind shield frame together with a portion of a window or opening frame or wind shield support and the interposed weather strip.

Fig. 2 is a sectional plan view showing the parts in disconnected or open position.

Heretofore it has been unusual to provide a weather strip normally projecting into the path of a swinging door or other closure member, which is adapted to be engaged with such member as it approaches its closed portion, and bent laterally or placed under tension whereby the weather strip through its elasticity is caused to bear upon the swing member or if carried by the swinging member is caused to bear upon the frame to close the intervening crevice. It is found however in practice that through uniformity of the, tension of the flexible strip, and variation of the surface engaged thereby, the

strip will not always conform closely to the contour of the engaged surface. This is partlcularlytrue after a long period of usage. In the case of automobile wind SlllGldS it is particularly desirable that all crevices be closed. To insure such complete closure, 1s one of the primary objects of the present invention.

Referring to the drawing 1 is the sash frame which is provided on its outer or marglnal edge with a tongue or bead 2 formlng at each side thereof a shoulder or rabbet 3. The wind shield support 5 or frame of the window or. opening is provided with a groove or channel 6 in which is seated a flexible weather strip. This weather strip is preferably of rubber composition or other resilient material. It may be constructed of an suitable flexible or yielding material. Viewing the strip in cross sectional form it comprises an enlarged base portion 7 from which projects a tongue or flange 8, prefeu ably though not necessarily wedge or V shaped. The base portion? is preferably though not necessarily inclosed in a channel or housing 9 which is clenched at its opposite side over the lateralportions or shoul-- said tongue or flange normally projects into the path of the swinging element, whether same be a wind shield, a window sash or dooras indicated by dotted lines. As the swinging member approaches the limit of its stroke it engages the flexible flange or tongue 8 and bends the same laterally. The swinging member continues this movement until the lateral shoulder or rabbet 3 of the sash frame rides over the top of the flexible flange or tongue 8 and the bead or tongue 2 of the sashframe engages a lateral face of the weather strip flange 8. If the strip is of uniform composition and flexibility 8 of the weather stripI will likely conform owever should there thereto throughout.

between the sash and be any inequalities window strip whereby the edge of the flange 8 will not adhere or conform closely to the contour of the sash, the resultin crevices will be closed by the enga ing 0 the bead or tongue 2 with the side 0 the flange 8 on a line somewhat removed from its edge. Thus the flange 8 and the tongue 2 not only overlap but the flange 8 has at its edge a lineal contact bearing on the shoulder or rabbet 3 in addition to its parallel lineal .contact with the bead or tongue 2 thus affording two separated parallel lines of contact in different planes. Further more the overhang of the shoulder or rabbet 3 beyond the edge of the flange 8 serves to protect any intervening crevice against the entrance of wind or rain. While the bead or tongue 2 has been-shown in the drawings upon the sash frame and the flexible weather strip mounted upon the support or window opening frame, it will be understood that therelation of these parts may be reversed and the bead or tongue 2 may be stationarily located upon the face or opening frame while the flexible weather strip ma be carried by the swinging element. he cross sectional form of the flexible strip may be varied or a thin flat strip may be substituted.

From the above description it will be apparent that there is thus provided a device of the character described, possessing the particular features of advantage before,

enumerated as desirable but which obviously is susceptible of modification in its form, proportion, detail construction or arrangement of parts, without departing from the principle involved or sacrificing any of its advantages. While in order to comply with the statute, the invention has'been described in language more or less specific as to certain structural features, it is to be understood that the invention is not limited to any specific details, but that the means and construction herein described comprise but one mode of putting the invention into effect, and the invention istherefore claimed broadly in any of its possible forms ormodifications within the scope of the appended claims.

Having thus described my invention I claim: j

1. The combination with two relatively movable bodies of a flexible flange or bead upon one of the bodies and two contact faces upon the other body angularly arranged in relation one to the other to forma rabbet, said flexible flange being extended into the path of movement of the other movable body and flexed by its engagement trant angle of the rabbet to be simultane-. ously engaged by the same side of the flexible flange or bead upon relative movement I of said odies.

2. The combination with two relatively movable bodies of a flexible flange'upon one of the bodies, and a rigid bead upon the other body forming withthe main portion thereof a shoulder or rabbet, the faces of the rabbet and the flexible flange being so proportioned and arranged in relation one with another that upon relative movement of the bodies the flexible flange will engage one face of the rabbet with a wiping contact until it abuts upon the second face of the rabbet thus filleting the'angle of said rabbet, substantially as specified.

3. The combinatlon with two relatively movable bodies of a bead carried by one of the bodies at a oint removed from the edge thereof, and a exible flange carried'by the other body, said flexible flange being adapted to engage the beaded body with a wiping engagement intermediate the bead and the edge thereof and to simultaneously engage the bead upon a line of contact separated from that of its engagement with the main portionof the beaded body.

4. The combination w th two relatively movable bodies of a flexible flange upon one of said members and a bead upon the other of said members, said flange and bead tane'ously engage the bead and said lateral extending contact face of the member car- 7 rying the bead substantially as specified.

5. A weather strip construction applicable to two relatively movable members com prising a flexible flange upon one of said members adapted to'fbe flexed laterally by. its engagement with the other member and an engaging portion upon the other member so shaped and arranged as to engage the convex side of the flexed flangeiupon independent "separated lines of contact.

6. The combination with two relatively movable members capable ofadjustment to and fro the one past the other, of a flexib le bead upon one of the members and a rigid bead upon the other member, extending into overlappin' relation, said flexible bead being adapte to engage-either side of therigid bead according to the direction of movement of the movable member and tion therewith to permit the movement of one member past the otherv member.
