SPECIFICATION forming part of Letters Patent No. 763,496, dated June 28, 1904.

Application filed January 26, 1904. Serial No. 190,728. (No model.)

To all whom, it may concern.-

Be it known that I, EDMUND H. LUNKEN, a citizen of the United States, residing at Cincinnati, Ohio, have invented certain newand useful Improvements in Window Constructions, of which the following is a specification.

My invention relates to windows of the general form disclosed in applications for Letters Patent of the United States filed by Bernard J. Hausfeld and myself as joint inventors September 14:, 1903, No. 173,118, November 27, 1903, No. 182,860, and January 9, 1904:, Nos. 188,199 and 188,200. In the type of window disclosed in said applications a secondary frame is pivotally supported in a main frame fixed in the window-opening, said secondary frame carrying a pair of sliding sashes which are balanced in suitable manner and in the case of a vertically-swingingsecondary frame are interconnected by rack and pinions or associated with pinions and toothed weights, whereby a constant balancing efl ect is maintained for all positions of the secondary swinging frame about its pivots.

My present improvements relate to the association with the sliding sashes of the secondary swinging frame, supplemental sashes to be carried by the sliding sashes and to move as one body with the secondary swinging frame.

The invention consists in the features and combination and arrangement of parts hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical sectional view through the main and secondary swinging frame with my improvement in place. Fig. 2 is a sectional perspective detailview. Fig. 3 is a sectional perspective view of a part of the sliding and hinged sashes with means for locking them together. Fig. 1 is a detail view in section of means for making a tight joint between the sliding sash and the hinged sash carried thereby. Fig. 5

is a front view of a part of a main and secondary frame with my lmprovement in place. Fig. 6 1s a detail view. Fig. 7 is a detail view showing the connection between the sashes whereby they operate 1n unison.

In the drawings, 1 lndicates the main frame,

which is of channeled metal and which is suitably fixed in the window-opening, and 2 indicates the metallic secondary or swinging frame, which is arranged within the main frame and swings about pivots connecting the secondary frame with the main frame. These pivots are indicated generally at 3, Fig. 5, the secondary frame in this instance being arranged toswing vertically about the horizontally-disposed pivots, though it will be understood that the secondary frame instead of swinging vertically may be arranged to swing horizontally, or, in other words, about vertically-disposed pivots.

My present improvements relate more particularly to the employment of a supplemental sash for each of the sliding sashes, such a combination being particularly desired in winter time to keep out the extreme cold. In carrying out my invention I combine with each sliding sash a supplemental sash connected thereto, so as to movetherewith in its sliding movement and also to partake of the general movement of the secondary swinging frame when the same is reversed in position to permit access to the opposite sides of the said frame and sashes carried thereby. The supplemental sashes are indicated at 4:, being hinged at 5 to the sliding sashes, so as to swing in a horizontal plane about vertically-disposed pivots or hinges. There may be only one hinged sash for each of the sliding sashes, as shown in Fig. 5, or the said hinged sash may be formed in sections, as indicated in dotted lines in said Fig. 5, the said sections when closed meeting at the central line of the sliding sash. In the present instance I have shown the hinged sash of a size to reach entirely across the sliding sash, and the hinge, as shown in Fig. 5, is located at the left-hand edge of the sashes. The hinge is formed by two eyes or sleeves 6, located at the upper and lower corners of the swinging sash, and an intermediate elongated eye or sleeve 7, fixed on the side rail of the sliding sash, a hinged rod 8, having a knob 9 at the top, passing through the said eyes or sleeves. When the hinged sash is formed in two sections, the same construction of hinge as just described is employed at the right-hand edge, and the same construc- IOO tion may also be employed when but a single sash is used to reach entirely across the sliding sash, excepting that in the latter case the hinged rod 8 would of course be wanting. In this instance the elongated eye or sleeve on the sliding sash would serve as a support for the eyes on the hinged sash and serve to center the hinged sash at this edge and prevent vertical p ay.

As shown in Fig. 1, packing 9is interposed between the hinged and sliding sash, being suitably fixed to the hinged sash. Instead of this form of packing a sheet-metal packing or Weather-strip may be employed, as indicated at 11 in Fig. 4:, said strip being secured between parts of the hinged sash and reaching across the space between the hinged sash and sliding sash in the curved form, (indicated at 11,) so as to form a free spring portion, which will accommodate itself to the space between the sashes and eifectually close the same against the passage of air, dust, or other elements.

In order to hold the hinged sash in closed position, I provide a lock consisting of a button or finger-piece 12, pivoted to a block 13, having a shank 14 screw-threaded into the side rail of the sliding sash. The hinged sash is provided with an opening 15 for the passage of the block 18 and button 12, and when the free edge of the swinging or hinged sash has been closed against the sliding sash the button 12 projects beyond the hinged sash and may then be turned into the position shown in Fig. 3 to engage the sash and hold the same in place.

In order to hold the sliding sash locked in position whether closed or slightly raised, I provide a locking-pin 16, adapted to engage openings 17 in the sliding sash, the said pin being carried by a spring-arm 18, which is screwed to the bead 19 of the secondary frame. The pinhas a knob 20, and by graspingthis the pin may be drawn out against the pressure of the spring-arm 18, and the sliding sash will then be unlocked, and when the lower opening comes opposite the pin and the same is released the lock will hold the sliding sash slightly elevated.

It will be seen from the above that the supplemental sash arranged as described does not interfere in any way with the use and operation of the window, as fully disclosed in the applications above mentioned, for the supple- The inner face of the upper sash may also be cleaned, and then by reversing the secondary frame the same operation may be gone through, and the upper sash, which is now in its reversed and lowermost position, may be cleaned on the outside, as well as both sides of the upper hinged sash, and the outer face of the lower sliding sash, which is now in its reversed and uppermost position.

By my construction I gain several advantages over the old method of double windows.

First. The supplemental sash can be attached to or taken from the guided sash without much d ifficulty and without marring the appearance of the sliding sash, the only part remaining on the sliding sash being the pieces 7 of the hinge, and they being long and cylindrical present the appearance of beads. The lock 13 is unscrewed from the sliding sash and a plug inserted to fill up the hole in the sash.

Second. Both the swinging and sliding sash are operated together, and a perfect circulation of air is assured, and, third, the inner and outer surfaces of both sash can be easily cleaned without the necessity of removing the secondary sashes.

Broadly speaking, my invention includes a supplemental sash hinged to a main sash, which in turn has a pivotal connection with the main frame, enabling it to be set in different inclined positions in the main frame, or, as in the present embodiment of my invention, the main sash may be reversed.

I do not limit myself to the manner of pivotally supporting the main sash'in the main frame nor to whether the supplemental sash is supported on the inner or outer side of the main sash, except as hereinafter noted in the claims. Again, whileIhave shown the swinging sash hinged at the sides of sliding sash I do not limit myself in this respect.

Fig. 7 shows a pinion 21 journaled in the frame and engaging racks 22 on the sashes, whereby the sashes balance each other.

I claim as my invention- 1. In combination with a main frame, aseeondary frame swinging in the main frame, a sash mounted therein, and a secondary sash hinged to the first-named sash, substantially as described.

2. In combination with a main frame, a secondary frame swinging in the main frame, sliding sashes carried by the secondary frame, and hinged sashes carried by the sliding sashes, substantially as described.

3. In combination, a main frame, a secondary frame swinging in the main frame, sliding sashes carried by the swinging frame, a hinged sash on the inner side of the lower sliding sash and a hinged sash on the outer side of the upper sliding sash, substantially as described.

4- In combination with a main frame, a secondary frame swinging therein, sliding sashes carried by the secondary frame, supplemental sashes hingedto the sliding sashes, a packing interposed between each hinged sash and the sliding sash with which it is associated, substantially as described. 1

5. In combination with a mainframe, a secondary frame swinging therein, sliding sashes carried by the secondary frame, supplemental sashes hinged to the sliding sashes and means for operating the sashes in unison, substantially as described.

6. In combination with a main frame, a secondary frame swinging therein, sliding sashes carried by the secondary frame, supplemental sashes hinged to the sliding sashes, racks on EDMUND H. LUNKEN.
