WINDOW.

SPECIFICATION forming part of Letters Patent No. 727,366, dated May 5, 1903.

Application filctl April 28, 1902. Serial No. 105,118. (No model.)

To all whom. it may concern.-

Be it known that I, JOHN HORSFIELD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Windows, of which the following is a specification.

This invention relates to improvements in sliding windows, pivot-windows, and combined sliding and pivot windows, and has for its object the construction of windows of these types that will be substantially wind-proof, that will be durable and efficient in operation, and simple and economical in construction.

This invention consists in the various novel features and detailsof construction, which will be pointed out hereinafter and shown in the accompanying drawings.

Figure l is an elevation of a sliding window constructed in accordance with this invention, parts being broken away to show the hidden details. Fig. 2 is a horizontal sectional view of Fig. 1. Fig. 3 is a detail showing a modified form of construction in which the groove in the sash-frame is dispensed with. Fig. is another detail showing a form of construction similar to that of Fig. 3. Fig. 5 is a detail showing a one-leaf spring closurestrip and a groove in the sliding strip for the pulley-cord. Fig. 6 is a sectional detail showing difierent forms of construction as applied to a metallic sash-frame. Fig. 7 is a sectional detail showing the position of the spring closure-strip when the sash is turned on its pivots.

A represents a window-frame of ordinary wood constructiomhaving grooves a. a for the sliding sashes B B. Metallic channels C are formed to slidingly fit inthe grooves a a, and are provided with tongues or heads 0, formed by bending .the metal in a fold, as shown. These tongues enter into channels or saw-cuts a in the frames.

D is a double-leaf spring closure-strip or jamb, constructed, as shown, with a tongue (1, formed by a fold in the metal taking into the groove formed in the bead c, then the two leaves spread at an angle, as shown at d, to engage the beveled edges b of the sash, and again bent in at d to engage the sides of the channel C. The sash is pivoted on pins E, which pass through the sides thereof and are secured at the outer ends to lugs e in the channels C. The leaf of the spring-jamb D is perfo rated to allow the free turning of the pin and the flexing of the spring. Balance-cords F may be secured to the top of the channels C and engage with any suitable balance pulley or spring at the top of the frame. Bolts or catches G are provided either at the top of the sash or at any other suitable point,whereby the sash may be locked to the channels to prevent turning when not desired. It will be observed that when the sash is raised or lowered the entire metallic jamb will move therewith, and the sash may be turned on the pivots at any point.

This invention is readily applied to old windows with but little change. Fig. 3 shows a convenient form for this purpose.- The sawcut in the frame is dispensed with and the sliding channel is provided with outstanding folds to form a groove for the spring-jambs. When a more perfect joint or weather-strip is desired, the form shown in Fig. 4. may be used. In this instance a tongned strip H is secured in the grooves of the frame and the sliding channel is provided with a fold to engage said tongue.

Fig. 5 shows a further modification in which a single-leaf spring-jamb is used and a chan-. nel shown for the pulley-cord.

. Fig. 6 shows the adaptability of this invention in its various forms of construction to a metallic frame.

In Fig. 7 is shown the position taken by the leaves of the jamb when the sash is turned on its pivots and also illustrates a convenient method of pivoting a simple pivot-window which is not intended to slide.

When this invention is applied to a window, it furnishes an absolutely wind and weather proof connection between the sash and the frame, which can be readily seen from the drawings. The various forms are shown to illustrate its adaptability to different constructions and modifications.

What I claim, anddesire to secure by Letters Patent, is-

1. In combination, a window-frame provided with channels, a sash having beveled side stiles pivoted in said frame, metallic spring-strips,extending longitudinally of said channels and projecting somewhat beyond the inner face of said frame, adapted to engage said sash-stiles and be flexed and pressed back thereby as the sash is swung on its pivots.

2. In a window, the combination of a sash, sliding channels adapted to move with the sash, jambs or closures comprising flexible metallic strips secured in said channels and adapted to engage said sash-stiles.

3. In a window, the combination of a frame, sash-grooves in said frame having narrow grooves in the centers thereof, slidable channels engaging said sash-grooves with tongues taking into said narrow grooves, spring-jambs secured in said channels and a sash pivoted to said channels having beveled side stiles adapted to engage said spring-jambs.

4:. A yielding jamb or closure device, comprising a strip of metal, folded to form a tongue, then bent to form an angular recess adapted to engage the beveled stiles of a sash,

then bent to form rentrant legs adapted to engage the side Walls of the sash-groove in combination with a sash provided with beveled stiles and a frame provided with grooves and saw-cuts or channels in the bottom of the grooves adapted to engage with said tongue.

5. In a window, the combination of a metallic frame bent to form a groove corresponding to an ordinary sash-groove, and provided with a fold in said groove, a spring closure device or jamb having a tongue engaging said fold and spread to form a double leaf to engage the beveled sash-stile then bent back to form legs adapted to engage the sides of said groove, and a sash pivoted in said frame.
