have invented new and useful Improvements in Window-Guards, of which the following is a specification.

his invention relates to a guard or closure for. producing a weather tight joint between the sashes and the frame of a window.

It is the object of this invention to produce a guard for this purpose which is simple in construction and efficient in operation and which will not interfere with the free-movement of the sash.

I In the accompanying drawings consisting of 3 sheets: Figure 1 is a fragmentary vertical section, on a reduced scale, parallel with the plane of the sash taken in line 11, Fig. 10, showing the guard applied to a window in which the sashes are capable only of a vertically sliding movement in the frame. Figs. 2 and 3 are vertical cross sections, on a reduced scale, taken in lines 2-2 and 33, Fig. 10, respectively. Fig. 4 is a detached bottom view of the lower sash showing the lower weather strip bearing against the same. Figs. 5, 6 and 7 are fragmentary vertical sections, on anenlarged scale, in lines 55, 66 and 7-7, Fig. 1, respectively. Fig. 8 is a fra mentary top plan view of the upper sash and the top weather strip bearing against the same. F' 9 is a fragmentary horizontal section in e 9-9, Fig. *6. Figs. 10 and 11 are horizontal sections, on an enlarged scale, in lines 1010 and 11-11, Fig. 1, respectively. Figs. 12 and 13 are. ragmentary perspective views of a air of cooperating strips for producing a tig t joint between the sash stiles and the frame jambs. Fig. 14 is a horizontal section similar to Fig. 10, showing my improved weather guard applied to a window in which the sashes are capable of both a vertically sliding and a rotary movement in the frame.

Similar letters of reference indicate corresponding parts throughout the several views.

The window frame shown in the drawings comprises a bottom or sill A having a stool a, a top or head B, sides or jambs C, inner and outer stops D, E applied to the jambs, and inner and outer stops F, G applied to the head. The head of the frame is provided intermediate of its inner and outer stops with a parting or check stop H which may be constructs d in one iece and each of the jambs has a parting or c eck stop constructed of upper and lower sections I, J represents the upper or outer sash which is guided at its edges in the channels or ways formed on the frame between the parting and outer stops and J the lower or inner sash which is guided in the channels or ways formed on the frame between the inner and parting stops thereof.

' The division or joint between the upper and lower sections of each side parting stop is preferably arranged at the junction of the meeting rails j, j of the sashes when'the same are closed, as shown at is in Figs. 1, 2 and 3. That part ofthe guard which produces a weather tight joint between each sash stile 7' and the adjacent jamb of the frame consists of two cooperating strips or members L, M. The strip L is carried by the sash stile and constructed of sheet metal which is bent to form an attaching or base flange land a channel 1 arranged at right angles to the flange and opening outwardly adjacent to the inner end of the attaching flange. The strip L has its flange Z secured to a vertical edge of one of the sash stiles by'nails Z or otherwise, and its channel arranged in a rabbet Z formed on that vertical corner of the respective stile which faces the adjacent partingor check stop of the frame. When thus attached to the sash stile the open side of the channel I of the stile strip faces inwardly or toward the adjacent jamb. Each of the jamb strips M is likewise constructed of sheet metal so as to form a longitudinal tongue m, an attaching or base web m arranged in rear of the tongue and connectedat its front edge by a shoulder or off-set m with the tongue, and a flange m arranged at the rear edge of the web and projecting in a direction opposite to the shoulder thereof. The web of the strip M is arranged between the side of a parting stop and the adjacent side of the groove n in the jamb which contains said stop, its flange m is arranged between the back of this stop and the bottom of said groove, its shoulder m engages with the adjacent corner of said groove and its tongue m projects outwardly into the channel of the stile strip, as shown in Figs. 10 and 11. are preferably secured to the parting stops y nails '12 passing through the webs thereof. The channels of the upper sash are arranged on the inner side of its stiles while the channels of the lower sash are arranged on the The jamb stri s ion stiles of the sashes on the same end the .vided with such strips.

' permitting the sash to slide vertically and also to move freely toward and from the jamb parting stop section and the opposing wall of of the respective j amb strip, the inner part of upper and lower sections of the parting stops,

In order check stop from its front edge toward its rear 1 edge, as shown at 11 Figs- 10, 11 and 14. The

-' beveled in this'manner on their outer sides outer side of its stiles, whereby the com anthe lower sections of the jamb parting stops and are of the same length as these sections but the outer sidesof these sections are not provided with such strips. When the jamb and stile strips are in their 0 erative position, the tongues and channels t ereof are interlocked and arranged .substantially parallel with the plane or side ofv the sash, whereby a weather tight joint is produced between the sash-and frame, while without pulling on the parting stop, thereby avoiding the tendency to displace the same which otherwise would be liable to occur.

stop sections'and interlocking the stile strips to-provide the necessary space between each the jamb groove for accommodating the web each arting stop section is reduced, preferably y be veling that side-of the parting or upper sections of the amb. parting stops are while those of the lower sections are beveled on their inner sides. By thus beveling the respectively, on opposite sides their front edges or faces are not reduced, thereby rendering the faces of each pair of stop sections uniform and even in appearance.

For the purpose of properly filling the the jamb groove, the web of the respective jamb strip is curved so that it bears at its crown against the beveled side of the stop and at its ends against the opposing side or wall of'the. jamb groove, as shown in Figs. 10 and '11. The jamb stripis preferably so bent that upon introducing the same with under tension which causes the parting stop 1 section to be held firmly against rattling. By engaging the rear flange of the jamb strip with the rear edge of the parting stop this flange serves as a gage for nailing the-- strip on the parting stop in position to properl cooperate with its stile strip. In assemb ing t e sash and the jamb parting sto s of the window when thus equipped wit my improved guard, the upper sec tions of the. jamb parting stops are first placed in the grooves of the ambs after which the upper sash is passed outwardly underneath said sections into the outer guide ways of the frame and then moved upwardly for engaging its stile strips with the upper jamb strips. It is possible to thus move the upper sash underneath the upper sto sections'masmuch as the joint between t e parting sto sections is at the meeting rails of the sas es and the upper sash is usuall somewhat shorter than the lower sash. gne of the lower parting stop sections is now put in place and then the inner or lower sash is engaged at one end therewith and moved upwardly its fullest extent in the inner ide ways of the frame. Finally, the other ower parting sto section is placed in its jambrgroove an then the inner sash is lowered so as to engage its stile strips with those on the lower sections of the jamb parting stops." When the inner sash is in its uppermost position its lower end extends a short distance below the joint between the stop sections. This however does not interfere with the placing of the final section of the parting stop inasmuch as this can be accomplished by taking advan-; tage of the slight looseness' between the parts and by slightl tilting or springing the final stop section w ile introducing its upper, end

behind ,the lower end of the inner sash.

When inserting the parting sto sections in the grooves of'the jambs the s oulde'rsfbetween the webs and tongues of the jamb stri s serve as stops which engage the face of t e j amb and determine the extent which the strip and stop can enter the j amb groove for causing the parts to cooperate properly.

If desired the nails which fasten the j amb strips to the parting stops may be omitted but it is preferable to employ the same because thelr usefacilitates assembling of the parts. Furthermore, by connecting the jamb strips with the parting stops, these I parts may beconvenlently removed together fromthe frame to affordfree access. to the usual weight pockets in the jambs when the sash balancing Weights requireadjustment. I

My improved construction of guard for securing a weather tight joint between the frame jambs and sash stiles is equally applicable-to windows in which the sashes are mountedv to rotate and also -mov e vertically in the frame, a wmdow of characterbeand hanging bars are connected by horizontal ivot pins or bolts q shown in dotted lines, W ich causes the bar and sash to move vertically together but permits the sash to tilt or turn on the bars. hen the sash is thus tilted, the cam action of the cooperating rib and groove of the hanging bar and sash causes the bar to rock transversely in the guide way of the jamb in a well known manner. JVhen these hanging bars are employed, channel strips L are attached thereto in the same manner as in the construction of window previously described in which the sash stiles. engage directly with the guide we s of the frame.

he construction of the guard for producmg a weather tight joint between the meeting rails of the sashes is as follows: E, R represent two similar weather strips each of which is constructed of sheet metal in the form of achannel. The opposing faces of the meeting rails are rabbeted as shown at 1', r so as to form a chamber between the same when both sashes are in their normal closed position. The rabbet on the meeting rail of the outer sash faces upwardly while that on the'meeting rail of the inner sash faces downwardly. In each of these rabbets one of the channel weather strips is secured in such. position that it cooperates with the strip of the other meeting rail for producing aweather tight joint between the meeting rails. The Weather strip of the outer meet ing rail has its channel opening upwardly and one of its flanges is secured to the bottom of its rabbet by nails 8. The weather strip of the inner meeting rail has its channel opening downwardly and one of its flanges is secured to the bottom of its rabbet by nails 8.

When the meeting rail weather strips are in l their proper position the front or unattached flange of each of these strips extends across or overhangs the path of the front flange of the other meeting rail strip. This arrangement of the meeting rail strips causes the same to engage each other upon closing both the inner and outer sashes, as shown in Fig. 6; and produces a weather tight joint between the same/ By thus arranging the meeting rail weather strips in rabbets formed thereon, these strips are concealed and produce a neater appearance than when the same are exposed. Furthermore, this construction permits of spreading the flanges of each meeting rail strip soas to allow for greater variations in the distance between the sashes without liability of interfering with the proper engagement of these strips with'eachother upon closing both sashes.

A weather tight joint is produced between the top rail T of the upper or outer sash and the head of the frame by a guard which is constructed as follows: U Figs. 5 and 8 re re sents a top weather strip constructed of s eet metal to form an attaching web a, a gage flange u arranged at the rear edge of the atedge ofthe attaching web and projecting in a direction opposite to said gage flange and a bearing flange 11, arranged at the free end of the wing. The web of the top strip is arranged between the outer side of the top parting stop H and the opposing wall of the groove in the head containing said stop, its gage flange engages over the top of the stop, its wing curves outwardly and downward y between the head of the frame and the upper sash, and its bearing flange projects downwardly and is arranged in line with a rabbet v formed on the upper edge of the top rail. The web is fastened to the top partin stop by nails n so that the same goes wit this stop upon'applying or removing the same from the groove in the head of the frame, in order to provide the necessary space for receiving the web of the top weather strip the upper or rear part of the top parting stop is reduced in thickness this being preferably effected by beveling 'the outer side of this stop from its front edge to its rear edge, as shown in Fig. 5. The web is preferably curved and bears at its crown against the taching web, a wing 11. arranged at the front parting stop. This web is slightly sprung into place so as to produce a snug fit between the parts which prevents rattling. The face of the top parting stop thus retains its full width so that it is uniform with the face of the parting stops of the jambs.

During the last part of the upward or closing movement of the upper .sash the upper rabbet thereof engages the bearing flange of the top weather strip and causes its wing to gradually roll or straighten out against the head of theframe, thereby pro ducing a tension on this strip which causes the same to produce a perfectly tight joint between the top rail of the upper sash and the head of the frame. By engaging the flange at the free end of the wing with a rabbet on the top rail any dust, rain or wind entering between the 11 per sash and the frame is directed over the top of the wing toward the base thereof where the course of and frame at this place absolutely weather proof.

&

The means for securing a weather tight joint between the frame sill and the lower sash in the closed position of the latterare as follows: w represents a bottom weather strip which is constructed ofsheet metal and which is secured along its inner edge to the sill adjacent to theouter side of its stool a by nails to and gradually curves upwardly toward its outer edge. The latter isadapted to engage with an inwardly-facing rabbet as on the underside of the lower rail y of the inner sash. During the last 'part of the downward movement of the lower sash its rabbet a: engages with the free outeredge of the bottom strip and gradually rolls or straightens the same downwardly against the sill. By providing a rabbet in the bottom rail for the bottom strip to engage with the incoming weather, such as wind, dust and rain, is prevented from passing over the free edge of the bottom weather strip but is directed underneath the same toward the base of the strip where the weather is effectu ally checked and turned back, thereby rendering this joint perfectly weather proof.

It has been found in practice that the free edge of the bottom weather strip when perfectly straight is liable to bear unevenly againstthe bottom rail and prevent rendering this joint tight. In order to overcome this the free edge of the bottom weather strip is curved conv'exly from its central part toward opposite ends, as shown in Fig. 4.

' When thus constructed the central part of the bottomv weather strip is engaged first by the bottom rail upon closing the lower sash and then this rail during the continued downward movement of this sash gradually extends its engagement with the bottom weather strip toward opposite ends thereof, thereby insuring a continuous contact of this weather strip throughout its length with the bottom rail when the lower sash is fully closed and effectively excluding the weather at this place.
