useful VIinproveinents in ll'indows, of which.

thc following is a specification.

This invention relates to .improvements in windows. and has reference vmore particularly, although not exclusively, to car winfy (lows. v

Certain features of improvement relate to the sash traine, which is constructed of sheet metal suitably bent to forni hollow Stiles and bars. reinforced to secure suiiicient strength ima rigidity.,

Other .features ot' improvement relate to a novel means of attachinga sash lock, with nreaxis"whereby the latter is caused to co operate with the sash guide in effecting a snug lit of the sash in the guide, and still other ininor features of improvement will hereinafter appear from the following. description of the invention.

illy invehtion will be readily understood,`

both with respect to its structural features andthe mechanical advantages and iin# provenients secured thereby, when considered in connection with the,4 accompanying drawings illustrating soinepractical enr bodiinents thereof, in which- Figure l'isan elevational View of a. portion. of a window frame or casing With the sash therein, the parts bein broken away both horizontally and vertically andthe base members of the inner-sash guides appearing in vertical section. Fig. 2 is. a verf tical transverse section on the line 2 2 of 4I" ig. l, viewed in the direction indicated by the arrows, and also showing a section of the sill and my improved sash-cushioning device monnted'thereon. Fig. 8 is a crosssectional detail on .the vline 3-3 ofJFig. l, .looking in the direction indicated by the arrows Figffl is a View similarto Fig. 3, but showing ldifferent forms of bent sheet metal' sash guides. Fig. 5 is a fragmentary front elevation of the lower corner part of the sash and sill shown in Figg2, viewed in the direction indicated by the arrow 5 in the latter figure. Fig. 6 is a fragnientary outer edge elevation of the sash and its guides, as viewed from-"theleft of Figs.l 1

and 3. Fig. 7 is a detail sectional View.

showing the' arched `form of glazing strip.

Fig. S is a detail longitudinal sectional view y 'through one of the hollow stile members showing the cross sectional shape of one of the,A rivets which connects the overlapping poiilions of said stile member.

l Referring to Figs. lto 3, inclusive, "and o and ti, 1 designates the sill, and 2 and 3 between them nido-grooves in which the Stiles ot the sasl are adapted' to slide. The guide- strips 2 and 3 are shown as substanon 'their outer sides lat' -ally projecting flanges by which they are secured to the jainb or casing by screws 4. In Fig. Ll, the guide-strips 2 and 3i are formed with inclined or oblique portions 2b and 3D, through which pass in an oblique or inclined direction the securing screws 5, this construction aii'ording 'a simple .means of insuringa .snug sliding tit of the sash in its guides' after the sash hasbeen inserted, by ,simply additionally turning up the screws 5. 6 designates as an entirety the upper and lower horizontal sash bars, and 7 the side bars or stiles of the sash, which are in all cases-formed from a sheet metal stripor a seamless tube bent tothe require-d crosssectional shape and provided with. an inder or stop for the margin of the glass 9.

channel-strips l0 of rubberor rsimilar ins the sash by glazing strips 11, each of these strips comprising a transversely elastic metal strip substantially triangular shaped in cross-section andrhaving inner and outer lips llvand 11b (Fig. 3) adapted to bear against the adjacent side of the insulator l0, 'said strip being secured by a series of screws strip. and tapped into the adjacent inner wall of the sash stile or bar; saidv screws vvpneilierably bein screwed into thiol: short riiets 13 by which the overlapping sections constituting the inner iva-ll of the stile lare l secured together.

tirety the adiust'ing strip which is preferably, Valthoug not' necessaril employed in connection with the other 'eatnres of the invention.` This adjustin strip is formed from a piece of thin resilient sheet metal that isbent .or doubled upon itseli on sub- .stantially its median Vlongitudine .,line, the inner portion being further bent Tongitudinelly to suitably 'engage the stile and in tially hollow sheet metal' members having wardly projecting lip 8 that forms a shonll lhe edges of this latter are embraced by` snlation, and the glass is securely held inv 12 passed ob iquely through the glazing'4 le designates as an en-' `the inner and outer stops or strips forming i i ro Losses@ of a sufficient longitudinal extent to permit the entrance of either tenori 6l or 62 and the `subsequent sliding movement of the other the tenori 6l. The tenons (il and 62, as best' fil) saslrmeniber and, the angle-piece vertically or horizontally,` s the case may be, toward theedge of the plate. to eiect the entrance of the other tenon to its proper Vposition in the other member. of the sash. For instance, the upright limb of thelangle piece 28 aft the lower left handcornerof Fig. 1 is slotted, mortised or recessed from its upper end downwardly at least to the bottom edge of shown in Fig. 2, are inwardly offset relatively to the plate 60, and the lock-casing 56 is attached. to said plate as by screws 65. To relieve 'the said screws of strain, l. pret erably extend the upper-end of theplite 60 and overturn the same, as shown at 66 (Fis.

2l to forni an abutment for the'upper edge of the lock-easing 56; while the lower edge of the plate G0 to one side of the tenori 62 is likewise preferably extended'und'tiirned up to Forni a shoulder or abutment 6T`(Fig. 2) iol' the lower edge of the lock-casing, By this4 means all vertical strains imparted to the lock-easingthrough the plunger are received and resisted by the integral abutnients 66 and 67 of the plate G0; and consequently all the screws are relieved of such strain.

While the plate' 60 as above described constitutes a hase or support for the lockeasing, it also performs an additional and valuable function as a corner iillet or reinforcement for 'the corner joint of the sash frame, thus permitting the use of relatively narrow Stiles and bars without detracting from the strength and rigidity of the sash frame, and thus permitting, through the employnent of narrow stiles and bars, a larger totalarea of glazing than'would otherwise be possible, y. By reference to Fig! 6 it will be observed that tlieopeningr 68 in the sash-guide inem-` ber 2 through which the locking plungers 57 of the lock enters is provided with an inclined Wall 69, and the face of the plunger 57 adjacent thereto is correspondingly inclined or beveled, as shown'atTO, the end' of the plunger 57 being shown in elevation. Furthermore, the cross-section of the plunger is somewhat. smaller than the area of the opening. B v reason ot this construction, when the plunger is engaged with the opening, the wei gli t of the sash acting;r through said plunn ger causes `the inclined side T0 of the plun ger to ride down the inclined edge 69 ofthe opening', .f'liich action forces the. Sash ster ally toward the opposite sagshuide 3. thus "producing a snug it between said guidefand the sash.

lvl/ith reference to the described internal reinforcement of the sash frame members, il.

maybe noted that, wliile'l have illustrated this reinforcement as applied to both the Stiles and hars, it is 'of especial advantage .in

its application to the horizontal bars, since they are subyected to the greater strain, the Stiles being to' some extent supported through their engagement with the guides.

While I have described and illustrated my improvements as applicable to windows,` yet I do not limit them to this particular appli.- eation to the extent that the various features `lot' constructionare or may be applicable to analogous structures, such as doors, panels.

and the like.
