DISAPPEARING. WINDOW.

SPECIFICATION forming part of Letters Patent No. 780,902, dated January 24, 17905.

Application filed August 31, 1904. Serial No. 222,814.

To @ZZ whom, t may concern:

Be it known that I, JOHN J. MLLER, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in thecounty and State of New York, have invented. a new and Improved Disappearing Window, of which the following is a full, clear, and exact description.

rlhis invention relates tothe construction of window casings and sashes, together with their attachments, the object of the invention being to produce an arrangement whereby the sashes may disappear in the easement of the window orin a wall in order toincrease the area of the opening of the window.

The invention consists in the construction and combination of parts to be more fully described hereinafter and definitely set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar characters of reference indi ing an attachment constituting a part of the invention. Fig. 5 is a horizontal section taken at substantially the height of the window-sill and representing a portion of the windowcasement and the sashes. Fig. 6 is a section somewhat similar to Fig. 5, but representing the sash-cords in a different position; and Fig. 7 is a horizontal section similar to Figs. 5 and 6, but representing a modified construction of Lan attachment for retaining the sash-cords.

Referring more particularly to the parts, 1 represents a window-frame the upper portion of which may be of any common construction,4 comprising guide strips 2, which comprise parting-strips 2br and beads 2a, forming rims 3V therebetween, through which a pair of sashes 4 and 5 may be guided in the usual manner.

These sashes are counterweighted in the usual manner, the counterweights being attached by means of the usual sash-cords 6, which pass over pulleys 7 into the interior of the casement of the window, as will be readily understood.

Below the sill 8 of the window the Casement thereof is formed into recesses or chambers 9 and 10, which are disposed directly below the guide-runs 3, in which the sashes 4 and 5 are guided. The chambers 9 and 10 are formed between solid panels 11, the said panels being respectively substantially in alinement with the beadsl 2, At the sides the chambers 9 and 1() are parted by centrally-disposed guidestrips 12, which constitute continuations of the parting-strips 2". o Y

As indicated most` clearly in Figs. 2 and 3, the gu ide-strips 2 are cut away at substantially the level 13 in order to enable the aforesaid sill 8 to slide into the position in which it is shown in Fig. 2. When in this position, the sill "rests upon the upper edges of the panels 11. Its upper face is provided with a weatherstrip 14, which is adapted to abut against the outer f ace of the lower portion of the sash 5v when the sashes are disposed in their closed \relation, as indicated in Fig. 2.

In order to prevent any possibility of the sash-cords 6 from interfering with sliding the sill 8 into position, there is provided a keeper 15, which is illustrated most clearly in Fig. 4. This keeper consists of a plate which is attached to the side face of the casing at the bottom of a recess 16, formed in the partingstrip 2b. It may be attached by means of screws 17, as shown, and its extremities project laterally across elongated recesses 18, which are formed in the face of the easement at this point. In this connection it should be understood that the recess 16 is in substantial alinement with corresponding recesses 19, which are all substantially at the level 13, so as to constitute a guide for the sill when slid into position, as will be readily understood. In order to enable the keeper 15 to perform its function of retaining the sash-cords 6, its extremities are formed into hooks 20, which curve slightly inwardly toward the bottom of IOO which the sash-cords 6 are attached in thel usual manner.

In operating the window when it is desired to have the sashes 4 and 5 disappear in the easement the lower sash 5 may be raised somewhat from its lowermost position, in which it is shown in Fig. 2. After it has been raised in the manner suggested the sill 8 would be slid inwardly in substantially the position in which it is shown in Fig. 3. The sashes would then 'be forced downwardly into the chambers 9 and l0. In forcing the sashes downwardly in this manner the sash-cords 6 would be found to lie in front of the keeperplates 15 in the manner indicated in Fig. 5. In order to remove them from the path of the sill 8, so as to enable the same to be returned, they may be pushed rearwardly7 into the recesses 18 until they are received behind the hooks or extensions20'in the manner indicated in Fig. 6. IVhen the sash-cords are stowed in this manner, the sill could be slid back into place, as will be readily understood. In order to facilitate the returnotl the sashes to their normal position, the upper edges thereof are provided with enlarged recesses 22, in which small handles 23 would be conntersunk, and these handles could be grasped to draw the sashes upwardly, as will be readily understood.

In Fig. 7 is illustrated a modified arrangement for maintaining the sash-cords in the recesses 18. IVhen adopting this form of the invention, the upper edges of the sashes are provided with grooves 24, which extend to the sides of the sashes, as shown, and aford means for guiding' plates 25, as shown. The outer edges of these plates are recessed, as at 26, and their side edges are provided with notches 27. Springs 28, thrusting against the inner extremities of the grooves 24.-, tend to force these plates 25 outwardly. Catches 29 are provided, which may engage notches 2i' in order to maintain the plates 25 in a retracted position. In Fig. 7 the plate used in connection with the sash 5 is held in this retracted position. However, when the plates 25 are released from the catches, as indicated in connection with the sash 4i, the plates will be forced outwardly by the springs, and their outer extremities will engage the sash-cords, forcing the same rearwardly into the recesses, as will be readily understood. It should be understood that the plates 25 in connection with their guides and springs are all countersunk into the sashes, so that they oiiier no ohstruction to the sliding in of the sill.

In practice where the sill of the windowframe is located so near to the Hoor that the sashes could not be housed in the space between the iioor and the sill it should be understood that the lower portion of the casement would be extended below the llioor, so as to enable the sashes to be received within the same in the manner described.

By means of the construction illustrated and described above a very simple arrangement is produced, enabling the sashes to disappear within the easing. Moving the sashes out of the frame of the window is often dcsirable, and especially for the purpose of increasing the ventilation. Such an arrangement is also desirable sometimes where it is necessary to more objects, such as safes, into a building through the window.

Having thus described my in yention,l claim as new and desire to secure by Letters Patent l. In a window construction, in combination, a easement, a sill movably mounted between the inner faces of said easement, sashes guided in said casen'ient and adapted to be depressed into the space below said sill, sashcords supporting said sashes and normally lying in the path of movement of said sill when said sashes are depressed, and means for defiecting said sash-cords from their normal position adjacent to said sill.

2. In a window construction, in combination, a easement, sashes guided therein, sashcords supporting said sashes, a sill adapted to slide in said easement, said sashes being deprcssible below said sill, said easement haring recesses adjacent to said sill, and means for deiecting said cash-cords into said recesses.

3. In a building construction, in combination, a easement, sliding sashes mounted therein, said easement having a recess in the lower portion thereof into which said sashes may pass, a sliding sill, sash-cords in connection with said sashes, said easement having recesses adjacent to said sill and adapted to receive said sash-cords, and a keeper projecting laterally across said recesses and adapted to retain said sash-cords therein.

In testimony whereofI have signed my name to thisspecilication in the presence of two subscribing witnesses.

JOHN J. MLLER.
