WEATHER-STRIP.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed September 22,1905. Serial No. 279,615.

'of Pennsylvania, have invented certain new and useful Improvements in Weather-Strips, of which the following is a specification, reference being had therein to the accompanying drawings, forming part of the speciiication, in which- Figurel is a erspective view of a portion of my improved) weather-strip as ap lied to Fig. 2 is asimilar view s owing a portion/of the interfitting sash member. Fig. 3 is a horizontal sectional view through a portion of the frame and sash, showing the parts in position and in interiitting enga ement with each other. Fig. 4 is a sim` ar view showing a modified arrangement employing a single-thickness tongue member.

ig. 5 is a similar view showing a modified construction of the'tongue member. Fig. 6 is a similar view showing the frame member in interiitting engagementwith the groove of the sash only.,` Figs. 7 and 8 are views similar to Fig. 1, showing modified forms of construction. Fig. 9 'is an end view showing a further modified construction. Fig. 10 is a horizontal sectional View of an open easementwindow or door provided with my improved strip. Fig. 11 is a similar view showing thewindow closed and the strip members in sealing engagement.

My invention relates to the class of metallic weather-strips wherein a weatherproof sealin -joint is provided between the sash and t e casing of a window-frame or be,- tween a door and its frame adapted to erl mitof the easy o eration of the sash or oor .,snow, dust, ce., from frame and sash or door.

and to exclude t e elements, as wind, rain, passing between the While the invention is particularly ada ted tothe sashes of sliding windows, it may e used with good results with the sashes of easement-windows or with hinged doors wherein the joint is made by causing one of the elements to close upon or open away from the other, as will be readily understood and as shown in the drawings.

Referring now to the drawings, lA re resents the sash member of the strip, whic is secured upon the inner sides of the runway of the. sash-frame by nails or screws passing through one or both of the flanges, as indicated at b in dotted lines, or by inserting the edges of the strip in suitable recesses or retaining-grooves c in the parting-beads or by merely inserting the edge-terminals underneath the parting-beads or in any other suitable manner. The frame member- A is referably formed of one continuous blan of ,thin sheet metal, preferably zinc or other suitable non-corrosive material, bent to provide the back or base port1on'2 of any suitable width, either of the full or greater width than that of the runway between the beads or of any less width, as may be desired. The sheet metal is redoubled upon itself at one or both edges and extends inwardly upon the outer side of the base 2, forming the outer base portion 3, which thus constitutes a. securing-flange for the device and also provides a smooth metallic face for the runway, against which the edge of thesash will bear with a minimum of friction, facilitating the opleration of the sash, while also giving a iinis ed appearance. At any desired location between thel terminal edges of the flange members the portions 3 are bent outwardly at right angles to the base, as indicated at 4,

and then turned inwardly, as indicated at 6,

forming extended parallel ribs rovided with rounded terminal edges 5, t e inwardlyturned terminal edges of the parts 6 of the strip being adjacent to each other. These sides 4'and 6 constitute redoubled walls of the outwardly-extending ribsand are parallel with each other, preferably with an intervening space 7, whereby a considerable degree of resiliency is provided, facilitating a tight `joint when in interfitting engagement with the rib member attached to the sash.

An intervening space 8 between the sides 6, of any suitable width, provides for the admission of the sash rib or tongue and is likewise useful to permit of the redoubled sides closing toward eachother, so as to makea tight interfitting engagement with the groove of the sash either with or without an additionalintervening rib as indicated in Fig. 6. The adjacent faces of the terminal edge portions 6 may, however, be in contact,v if desired. If preferred, the sides 4 may be merely bent around inwardly, providing the loo rounded terminal edges 5', as indicated in, Fig. 8, and do not necessarily extend backwardly toward the base 2, and good results may be had with both forms. struction smooth rounded edges of thel'ibs are provided, obviating any roughness `or sharp corners and overcoming any objections In eitherv con- I .l O

Y plate bein due to the danger of cutting or of interference with a cleaning implement or cloth.

' B represents the sash member, which is formed, as shown in Fig. 2, of a strip of similar thin sheet metal bent or doubled atits middle portion to provide an extended rib 9, having a rounded edge adapted to intel-'fit between the parts 6, as shown in Fig. 3, the redoubled outwardl at each side, provi 'ng the spaces 10 an the outer walls 1 1,\ This sash'element is secured within a suitable groove in the sash in any convenient. manner, as by tacks or nails d, in-

serted through the base of the device, as shown, along the bottom of channel-openings 10. If preferred, however, a single thickness of slieet metal may be used, as indicated at 12, Fig. '4, or sucha single sheet maybe bent into U form, as shown in Fig. 5, providing the projecting interfitting ton ue 13 and attaching-flange 14, while any ot 1er suitable form may bev used for the same purpose. If preferred, also the strip A may be merely inserted within the interior of the groove of the sash without any other interfitting sash member and will give good results, while bein more economical.

An especial a vanta e in the construction of the frame member A 1s that the outwardlyprojecting ribs, formed of parts 4 and- 6, beingindependent of each other,-will have sufficient resiliency to permit of their lateral adjustment toward or from each other, so as to make a tight joinin engagement with the sash-groove indepen ent of variations in its width, due to shrinkage, expansion, or any other cause. I

' `In Fig. 7 I show a modiedform of the frame-strip A, wherein the back base 2 ,and 4o the front base 3 extend at one side only of the outwardly-projecting ribs, the construction otherwise being the same as just` described. A claim covering this construction broadly is embodied in my copending application, filed March 6, 1905, Serial No.

248,382. This form is equally advantageous 'in all essential respects and only differs in the construction above noted in the omission of one of the base-flanges. It will be understood that when but a single base-flange is used it may be of any width desired to cover all or a portion only ofl the runway at one side of the ribs or to providefor the easy lateral adjustment of the strip-to correspond to aVvariably-located groove in the sash, asmay be required by local conditions in applying Y the device.

l @In Fig. 9 I show a modified construction in y which the projecting ribs 4, extending outwardly from the base 3, are doubledy in a reverse direction, the free edge-terminals 6? being on the outside, while the inne-r Walls 4f of the ,ribs are bent outwardly from the baseflanges 3" at right angles, as already described, preferably with the intervening are also rounded, and an intervening/space 7 is also preferably -provided between the sides forming each rib in the same manner generally as already set forth.

lIn Figs. 10 and 11 I show the strip inthe form illustrated in Fig. 7 as applied to each sideof the frame and window, respectively, of a casement-windowor door 15, hinged at 16 and provided at the hinge side with a male member 17 of any suitable form to conveniently enter between the rib portions of the frame members; On the other side the arrangement is reversed, the male member being attached to the frame gand thefemale member Ito the window. The male ,members are conveniently made of la single 4strip of sheet metal doubled upon itself at one edge to provide an entering'element of considerable stiffness and to also give it the desirable rounded edge 18. It is preferably bent at its middle portion to provide the narrow conneeting element 19 and an attaching-Harige 20, whereby sufficient clearance is provided for one side of the female member, while the entire strip is easily and firmly attached, v

does not-occupy much space, and is somewhat ornamental. It will be understood also that the same construction may be applied tol the top andbottom of the window, &c.

A weather-stri comprising a sheetmetal blank do'ubledpu on itself to provide an attaching-base an edge portions bent outwardly at right angles to the base and `bent upon themselves to form doubled ribs, with an intervemng s pace between the ribs, substantially as set forth..

8. As an improved article of manufacture, a weather-strip formed of a strip of sheet metal, having its opposite edges bent to provide closely adjacent doubled ribs, with its intervening portion formed into 'an attachingbase at right angles to said ribs, substantially as set forth. 9. A weather-strip comprising a sheetmetal base, flanges connected therewith and extending inwardly toward each other having their terminal edges bent outwardly at right angles to said base and turned inwardly toward each other to form outer rounded edges, substantially as set forth.
