To all whom it may concern:

Be it known that I, Enwix R. Pnonnur, a citizen of the hinted States of America, and a resident of Covington, in the county of Kenton and State of Kentucky, have invented a certain new and useful Improvement in Metal-Vindow Meeting-Rails, of which the following is a specification.

This invention relates to safety interlocking-formationsalong the meeting-rails of metal window-sashes whereby the undue entrance of fire, smoke, draft, dust, water and other deleterious elements is prevented and especially at the weakest or most vulnerable point for such elements to enter a buildingstructure through a closed window.

The object is to provide the meeting-rails with deep frictionally-engaging tongues and grooves on both the upper and lower edges of the rails and having an air-space or in sulating-chamber between them to collectively and thoroughly oifset the flames or smoke from a fire without.

The details of structure for carrying out the said object of the invention herein will be fully hereinafter described and particularly pointed out in the claim.

I In the accompanying sheet of drawings,-

- Figure 1 is a vertical diagram-section partly in elevation, taken on the dotted line a, a, of Fig. 2, and showing my improved meeting rail structure as applied to a pair or set of closed, hollow, sheet-metal window-sashes, the side-stiles of the latter being broken off on lines near their respective meeting-rails; and Fig. 2 is an outside elevation of the type of metal Window to which my invention is especially adapted.

1 in icates the upper-sash and 2 the lowersash both incased for vertical, sliding movewent in a suitable-frame composed of the 1 ".ial upright-members 3, 3, sill 4 and head 5.

As my inventiongis especially adapted for use in connection with sheet-metal windowstructures formed with hollow walls and resultant or consequent insulator-chambers throughout, and, more particularly, intend ed to meet the rigid requirements of underwriters in the quest for protective-insurance on property in which the windows are installed, I will. now describe the detalls or the meeting-rail joint or closure just as Specification of Letters Patent.

Application filed March 13, 1915. Serial No. 14,259.

Iaicntndbec. '7, I915.

they appear in Fig. 1, and that orm 1 mm:

effective fire-retardant at the least roam ent outlay.

The sheets or strips of metal use: in forming each of the meeting-rails are identical, as both rails are alike except that the 'recess 0r groove for the glass-sheet in the 6 along one edge, and then right-angles at 7 into a vertical stralght outer wall S; thence again right-angles at 9 into a short, horizontal top-limb 10; thence takes an imitationmolding curve 11 till it reaches a short horizontal top-bend 12; thence it is formed into a slightly tapered glass receiving groove 13; thence it passes onward into a horizontal top-limb ll alined with limb 12 thence it descends with a vertical fore-wall 15 till an angle 16 is reached, and thence into a right-angled upturned-edge 17.

A narrower strip of metal is used as a horizontal or bottom filler 18 between the.

first-named hook-end 6 and the upturnededge 17. and is bent into hook-form at 19 to interlock with said hook-edge 6, and then further bent along its opposite edge with a vertical downwardly-turned hook-edge 20 that interlocks with the said upwardlyturned edge 17.

deep vertical tongue is provided by the interlocked hook-edges 17 and 20 that projects at a right-angleupwardly from the edge of the bottom or filler member 18 that then extends inwardly toward the inner meetingrail A.

The reverse order of the same parts or formations, (except in connection with the glass-sheet grooves referred to above,) in the sheet-metal occurs in the meeting-rail A of the lower-sash and is enumerated to harmonize or correspond.

material than that of the meeting-rails, (as

distinctly shown by contrast in Fig. 1) and is composed of two sheets or strips of metal, one for the upper-sash rail 1 and the other for the lowensash rail 2. These strips are each bent alike, and. each begins with a right angled member 21 that extends into a vertical side-wall E, thence into a flaringlimb H; thence into a deep-folded doublelimb I that extends thence at J along the said flaring-limb H, and ends with a straight short end that laps on the outer face of the side-wall E for riveted-connection K. The contacting, flaringportions H and J'space the vertical folded double-limb H away from the adjacent face of the meeting-rail to which the stripis riveted at K, whereby a deep groove or slit is provided for the tel-lapping engagement or seating of the tongue formed by the interlocked hook-edges 17 and 20. It will be observed that the vertical extensions or ends of the right-angled membersfll lie between the said interlocked hook-edges 17 and 20, and are firmly compressed together to make a stifi and strong tongue along the interlocking upper and lower edges of two diagonallyopposite cor-.

"ners of the tire-retardant hollow guard that intervenes between the two meeting-rails.

The drawings show space between the parts of the tongues and in the grooves at both sides of the tongues, but it is obvious that such space is not really present in the device itself and should not be, as the tongues should frictionally-engage the grooves to as sure effective service when needed.

The heavier-metal hollow-guard forms a st-iii and substantial reinforce between the two meeting-rails to assure the desired firm and tight interlocking of the tongues in the grooves thereof, and no fire an pass this guard when the full engagement of the tchgues and grooves is eitectedJ I claim In a metal windowstructure comprising a pair of sashes, a pair of spaced meetingraills on said sashes each having oppositely but inwardly disposed L-shaped or rectangular flanges on their outer edges and inclosing the space between said meeting-rails. a pair of metal strips one fitting in each of the L-shaped flanges, the opposite edge of each of said strips being offset from its cor responding mi'eetinga'ail to provide a recess for the reception of the extremity of the L-sha ped flange of the othermeeting-rail in said recess.
