T all whom it may concern:

Be it known that I, ERNEST Franc, a citizen of the United States, residing at Non York city, county and State of New York, have invented certain new and useful im- .provements in Metal Window-Sashes, of

-proportion, and combine the various elements of a window, comprising sash, frame, etc.-, that the structural qualities peculiar "to bent metal will be employed advantagemisly,

to minimize the amount of material nccos-.

sary to such construction thereby making the window frame as a whole very much less in WSiPht and easier to be moved.

In this general type of window it is customary to r'bvide a sash and one or more panes seatcl thereon, so that a metal surface or part is on each side of the mar in of the pane, the pane being held positively by the sash.

.A further object of thisinvention is broadly to: rovide for a ready adjustment as an entirety or any of the rails of the sash, thereby making the removal of the glass very.

simple and easy of accomplishment.

A further object is to provide an el'licient reinforcing means for thecorncrs of the sash, which shall be readily'accessiblo and may be easily and quickly detached.

Further objects are to provide an ellicient metal muntin and bent metal sash rail; fur thermore, to rovide a sash comprising bent metal rails o the same cross-section and also to rovidc a suitable metallic window frame w iich will cooperate with such a sash.

The end and scope of my invention will be more fully understood from the following description, taken in connection with the accom anying drawings forming part hereof,

.in w rich z-- Figure 1 is a sectional elevation taken through line 11 of Fig. 2; Fig. 2 is an in- 'terior elevation of the window, but with parts broken away; Fig. 3 is a horizontal section through line 3--3 of Fig. 2, but showing window complete; Fig. 4 an enlarged locking device for the upper sash; Fig. 6 is an ting marginal Hui enlarged detail section. showing the meeting ends of the upper and low-gr sashes; Fig. 7 is an inunelric rim; of :1. portion of the top and side rails of the h. and liov-;ing the reinfoming angle ii view showing in d the end of the muntin; and Fig. l) is on ilargcd detail section taken along the lino l; -E. of Fig. 2, slunving the closure for the opening in tho jamb by which access may he hnd to the sash weights.

Referring now more in detail to the draw- --1 designates the. window frame, which comprises jambs and 3, sill and head 5. The upper and lower are designated by 6 and 7 respectively. Fig. 6 as shown, comprises stiles or

vertical nails

8 and 9, top rail 10, bottom rail 11, and muntin '12. The top rail of sash 7 is d si j natr-d by l3 the bottom raii by 14, the riaht hand stil by '15, and the inuntin by 1.6.

'p of shoot nictal is bent on. i. tom a rectangular molding U-shapo in i-ross-soctimi, having parallcl faces 22 and 23 substantially at right angles to face 24. The edge of the metal strip continuing from face 212 is bent out at right angles to form border or'aunrginal lhmge 25. By this construction, the inwlosod portion of the moldi. i'ul i-;tii".lll.(:- so, while the exterior faces '32, All. and 24 form the runner menilL-or for the vertical rails or stile This rail construction may be made in stock lengths, and then cut into pro )cr lengths for the respective sash rails, each rail bein pro'fcrably miter-ed at its ends.

This feature ermits a pane to be easily inserted or rem'oveil from the groove seats of the sash. Cement may be used in seats 26, as shown. The reinforcing angle irons are upon the outside of the sash, where .the are always readily accessible.

"l he sash bar or'muntin, shown in detail in Fig. 8, comprises two angle irons or strips 30, and a T-iron or strip 32. The latter may be formed by suitably uniting two metal strips. The tongue 33 of'the i -iron is of suflicient wid th to serve as a separating wall or partition, and to extend flush with the angle angle irons.

pieces 30 30. It is provided on either end with a screw 34,.and an extension 36, corresponding indength with the groove pane seat 26. The several parts of the muntin may be secured together 111 any suitable manner; so as toform groove pane seats 36 on either side of the tongue of the T-iron, between the head of said iron and the projecting wings of the When a sash is built up from rail construction of the section shown, the ends of the muntin abut against the inner faces of the marginal flanges 2-5 of thetop and bottom sash rails respectively, the extensions 36 fitting snugly 1n the pane seats 26, and the screws '34 projecting throu h the holes provided in the flanges 25. hen the muntins are locked in position by threading nuts 35 upon the ends of the screws 34, the muntins provide intermediate groo've seats for the anes, and constitute a rigid intermediate brace for the top and bottom sash panes.

Each jamb comprises a bent metal shell formed of a single strip of metal. The pul -ley face of each jamb is formed. with an integral parting ridge 37, with vertical side edges 38 and 39, at right aiigles to the faces 40 and 41' of the j amb. The sash slide in the rabbets on opposite sides of this parting ridge, as shown. The outer portions of the stiles or vertical rails 8 9 slidmgly engage the vertical faces 38 and 39, and are retained in place by vertical guides, preferably angle strips 42 43, which are removably secured to -.ja'1nbs as shown.

Mounted'in the j'amb there may be prIon Fig.- 5,such a fast is indicated at 44, havin a jaw 45, which may be clamped a ainst the rail 9, through the hole 46, provided in the Vertical face 38." Another construction of a sash fast is shown in Fig. 4, at 47, having a jaw which may be clamped against the rail 15, through the hole 49 provided in the vertical face Each jamb provides suitable runways for sash weights, indicated by 50. A separating strip 51 may be provided as shown.

52 indicates suitable pulleys over which i the cords or chains 53 may run.

Removable sections may be. provided in the jambs to give access to their interior, such a section being indicated b' the closure 54. This closure, shown in enfarged detail section in Fig. 9, consists'of a metal late having inturned edges adapted to it in grooves formed by the folded metal rims about the opening in the'side 3 of the jamb,

and it may be locked in position by a clamp or thumbpiece 55. In the embodiment of the invention illustrated, the parting ridges 37 separate the sash a distance slightly more than the width of the marginal flange 25. In order to prevent rattling, the lower rail of the upper sashis provided on the under side of the marginal flange 25 with a spring 56, as illustrated in Fig. 6. When the window is closed, the spring 56 engages the outer face of the top rail of the lower sash, in the manner shown, and prevents the rattling of either sash.

The head 5 is similar to the jambs 2 and 3, 1 v and is provided in the same manner with angle strips 57 58, to close against the outer face of the sash rails.

The sill 4 comprises a bent metal shell, open at the bottom, and preferably filled with concrete, indicated by 59. face has an exterior inclined portion or shed 60. A horizontal ledge 61 runs along its inner edge, and partly overlies the shed 60. An angle strio62 is preferably secured to the ledge 61, to face against the lower rail of sash 7. A depending weather stri 63 may be secured to the outer. face of the lower sash rail, which will pass below the ledge 61.

It is understood that this invention is not limited to the embodiment shown, and that many parts may be modified within the scope of this invention and furthermore that -many individual elements and combinations construegee heretofore fo and to. be necessary.
