12 Claims.

The invention is a window in which a pane of glass is 'slidably held in grooves and means are provided for raising and lowering the glass and also for counterweighting the glass, and it is so arranged that a window frame is not required and also so that the glass may be cleaned as it is raised and lowered.

The object of the invention is to provide a window in which the maximum amount of open area is obtained.

Another object of the invention is to provide a window in which the glass may be raised and lowered with very little effort.

Another object of the invention is to provide 'a window in which the glass may be raised and lowered from a remote point.

Another object of the invention is to provide a window which is so constructed that a plurality of windows may be controlled so that 0 they may be opened and closed from a remote point or points.

Another object is to provide a positive locking means for holding a window glass in any position.

A further object is to provide a window that will automatically clean itself as it is opened and closed.

And a still further object of the invention is to provide a window without sash or frame, which is of a simple and economical construction.

With these ends in View the invention embodies a window pane, grooves-in which the edges of the said window panes are mounted, a counterweight for said window pane, means for raising and lowering said window pane, and means for cleaning said window pane as it is raised and lowered.

Other features and advantages of the inven- 4 tion will appear from the following description taken in connection with the drawings, wherein:

Figure 1 is afront elevation showing the window with the glass in a partly open position.

Figure 2 is a cross section thru the section shown in Figure 1. 1

Figure 3 is a detail showing a cross section thru the edge of the window glass.

Figure 4 is a detail showing a cross section thru the window sill showing a means for cleaning the glass.

Figure 5 is a section with parts omitted showing an alternate arrangement in which the counterweight is placed on the outside of the window instead of on the inside as shown in Figure 2.

Figure 6 is a similar view showing another alternate arrangement in which a double window, or storm sash is provided.

Figure '7 is a view similar to that shown in Figure 2 in which the window is formed with two panes of glass with one glass moving upward and the other downward to open the window.

Figure 8 is a front elevation showing one side of the window shown in Figure 7.

Figure 9 is a detail showing a section thru one side of the window shown in Figures 7 and 8.

Figure 10 is a similar section showing a window of an alternate arrangement.

Figure 11 is a detail showing a method of attaching a cable to the lower corner of the upper glass in the design shown in Figures 7 and 8.

In the drawings the window is shown as it would be made wherein numeral 1 indicates a pane of glass, numeral 2 a counterweight, and numeral 3 a crank by which the glass may be raised and lowered.

The glass 1 may be of any shape or design, or of any thickness, and may be clear, frosted, or stained, or prepared in any other manner. In the design shown the glass 1 is of a substantial thickness and the vertical edges are slidably held in a felt strip 4 in a groove 5 in the building wall at the sides of the window opening, as shown in Figure 4. But it will be understood that the groove 5may be of any shape or design and any other means may be used in place of the strip 4 in order to hold the edges or" the glass and prevent Water or air passing around the edge. At the lower edge of the glass 1 is a clip 6, as shown in Figure 2 and it will be noted that the glass may e attached to the counterweight 2 thru this clip by using a cable or chain 7 that may pass upward over a pulley 8 and then downward to an eye 9 on the counterweight. It will be noted that one of the chains '7 may be used at each end, as shown in Figure 1, however, it will be understood that one or any number of chains may be used. The clip 6 is also attached to a vertical chain 10 which passes over sprockets l1, l2 and 13, as shown in Figure l. Sprocket 13 may be oper- 10o ated by the crank 3 and with the clip 6 attached to the chain 10 at the point 14. It will be noted that as the crank 3 is rotated the window will be raised and lowered, and as it is possible to provide any gear ratio desired it will be possible to reduce the load on the crank so that very little effort is required to raise or lower the glass. The counterweight 2 will also balance the glass so that the crank 3 is only requiredfor moving the glass and it is not necessary to lift the glass by in the upper end of the counterweight.

which will raise and lower the glass.

the crank as the glass is being moved. It willl be noted that the sprocket 13 may be omitted and the crank 3 located on the sprocket 11, as may be desired. It will also be noted that the chain F may be operated by a motor 15, as shown in Figure 5, and it will be understood that the motor may be operated by a switch at a remote point so that it will be possible to open or close a window from a remote point or open and close a plurality of windows at the same time from a remote point. It will also therefore be noted that in a large building having many windows it will be possible to have a master switch thru which all the windows may be opened and closed at the same time thereby making it possible for a person in the office to press a button and clean all of the windows in the building.

In the design shown in Figure-5 the motor 15 is mounted on a bracket 16 having a' sprocket 17 similar to one of the sprockets 11 or 13 at the.

that the weight of the glass will move the glass and'chain downward and the motor will move the glass'upward. It will be understood, however, that a reversible motor may be used so that the glass 1 may be positively raised and lowered as may be #1 desired.

In this design the counterweight, which is indicated by the numeral 21, is located on the outside of the glass instead of on the inside, as shown in Figure 2, and it will be noted that thecounterweight is supported by a cable 22, one

3' end of which is attached to the clip 20 at the lower end of the glass and the other end attached to the outside of the window-sill, as shown at the point 23. The cable passes over a fixed pulley 24 in the window-sill and also around a pulley 25 It will also be understood that the counterweight may be located at any other point and may be connected to' the glass by any other means.

In the section shown in Figure 4 strips of felt,

-' rubberor any other material, as indicated by the numerals 26 and 27, are attached to the top of the window frame by clips 28 and 29 and it will be noted that with the edges of these strips bearing against the glass the glass will be wiped every '=-=tirne itis raised and lowered and when it is desired to give it an extra cleaning water may be placed upon the glass or strips. It will therefore be noted that the glass may be thoroughly cleaned as it is raised and lowered.

In the design shown in Figure 2 a dog 30 is pivotally mounted on a pin 31 and is positioned so that normally it will rest against the inner surface of the window glass as indicated by the dotted lines shown, however, when the glass is -*raised' above the dog the dog will drop to the position shown in full lines and as the glass is lowered it will rest upon the dog which will hold the glass and prevent its being lowered. It will be noted that this device provides a very efiicient lock, as with the glass in the position shown in Figures 1 and 2 and with the dog 30 in the position shown it would be absolutely impossible for anyone to force the glassrdownward from the outside of the window. The device therefore holds the glass and also looks the window. A spring 32 may be provided to resiliently hold the dog against the glass and insure a positive movement of the dog to the position below the glass when it is desired to lock the window. A button 33 may be provided, as shown in Figure 2, which may be pressed inward to move the dog from the position shown in full lines to the position shown in dotted lines so that it will release the window and the window may then be opened.

In the design shown in Figures '1 and 2 a glass panel 34 is shown above the window opening. It will be understood that this panel may or may not be used, as may be desired, and may be made stationary, or removable, or hinged, preferably at the bottom, and operated as a transom or in any other manner. It will also be understood that any number of similar panels may be used in combination.

At the top of the window is a compartment 35 in which ashade, blind, awning, screen, or other similar device as indicated by the numeral 35 may be mounted upon a roller 37 and it will be noted that this device may be drawn downward when itis desired .to shade or protect the window. This device may be made similar to a venetian blind or in any other manner, and may be operated by a cord 38 which may be held in a fastener 39 inthe side of the window and it will be noted that when it is lowered and projected outward, as shown by the dotted lines it will act as a shade to the window and also assist in the circulation of air thru the window. The slats of the device which may rest against each other to close the device, or which may be held slightly apart will cause the air to pass upward between them and the window glass and into the upper part of the window. Theposition of thedevice may be adjustedso that it will be possible to obtain any desired circulation thru thewindow. noted that any other means may be used for raisinga-nd lowering the device and alsofor holding itoutward or inany position.

It will also be 'understood that one or more devices maybe used in the compartment 35 as a screen may be used in combination with the blind and the screen may be mounted and operated in any manner.

In the design shownin Figure 6 the window is provided with an outeror storm glass similar to storm sash and providing a double window. Tliis'maybe made stationary or operated in any desired manner, however, it is preferable to mount the outer glass ina similar manner to the inner glass so that'both may be operated by the crank 3, and it will also be appreciated that both may be operated in unison or independently or in any other manner.. In the design shown in Figure 6"the inner glassis designated by the numeral land the outer glass by the numeral 40. 4

The inner glass may .be operated by the crank 3 thru a shaft l1, as sprocket l2 and a chain 43 and it will be notedthat the chain 43 passes arounda'sprocket 44 at the bottom, which is It will'be tothe window sill at the points 52 and 53, andigg any other manner.

the opposite end may be attached to the clip at the lower end of the glass. The cables pass around pulleys 54 in the weights and 55 in the sill, as shown. It will be noted that the sprockets 44 and 46 may be located in the same position as the sprocket 12, shown in Figure 1, and it will also be understood that any other means may be used for operating the outer glass either with or independent of the inner glass.

In the design shown in Figures 7 and 8 the window is formed with a lower glass 56 and an upper glass 57 with an H shaped piece of material forming a bead 58 at the lower end of the upper glass and adapted to receive the upper end of the lower glass as the window is closed. It will be noted that with a window arranged in this manner the two panes of glass will meet at the center and when the window is opened it will open at the center, as shown in Figure 7, with the lower glass moving slightly downward and the upper glass moving upward. The crank 3 and the sprockets and chains connecting the crank to the glass may be arranged similar to the sprockets and chains shown in Figure 1 or in In this design the counterweight is omitted and the upper glass 57 forms a counterweight for the lower glass as it will be noted in Figure 8 that a cable 59 is attached to the lower glass at the point 60 and to the upper (glass at the point 61, after passing over a sprocket 62 at the top, so that one glass will counterweight the other and assist in the movement thereof. It will also be understood that each glass may be operated independently and the lower glass may be operated similar to the glass shown in Figures 1 or 5, or in any other manner. The upper glass may also be provided with independent operating means and this may be arranged in any manner desired.

In the detail shown in Figure 9 a section thru the upper portion of the window is shown in which a recess 63 is provided for one portion of the cable 59 and a recess 64 for the other portion. In this design the recess 64 is covered by a metal plate 65 having a felt lining or cover 66 and being held by screws 67. This recess is formed on the outside of the window and on the inside is a bead 68 which is held by screws 69 and a strip of felt, or any material 70, may be held by the bead 68 as shown.

Figure 10 shows an alternate arrangement in which the recess 63 is omitted and the cable passes'down thru a recess 71. The cover for this recess and also the bead 68 are similar to those shown in Figure 9.

In Figure 11 the cable 59 is attached tov the lower edge of the upper glass 57 by a clamp 72 and it will be noted that the end of the cable is attached to an eye-bolt 73 which may be held by nuts 74 and 75. It will be understood, however, that this cable may be attached to the glass in any other manner.

The upper end of the window shown in Figures 7 and 8 may be formed with a stationary glass panel 76 with the lower end held in a member 77 and the member 77 may be provided with a slot 78 thru which the upper end of the glass 57 may pass. The panel 76 may be formed as shown in Figure 1, or may be of any shape or size and may be omitted if desired. The upper end of the window may be shaped or formed in any other manner. This panel with the member 77 will form a seal for the upper end of the window and the member 58 which extends from one side to the other will form a seal or closure between the upper and lower glass so that the window will be completely sealed. It will be noted that the upper end of the window may be formed in any other manner and also that any other means may be used for sealing or closing the two abutting edges of the glass.

It will be understood that other changes may be made in the construction without departing from the spirit of the invention. One of which changes may be in the use of the glass with the operating means in a window of a different type or design, another may be in'the use of other means for providing a counterweight for the glass, and still another may be in the use of other means for operating the glass.

The construction will be readily understood from the foregoing description. In use the-device may be constructed and provided and installed as shown and it will be noted that as the counterweight is somewhat heavier than the glass, approximately one and one-half times the weight of the glass, the glass may be raised and lowered very easily and by turning the crank 3 the glass may readily be lowered to any desired position so that the window may be opened and closed as desired. It will also be noted that the window may be locked in any position, and with the construction shown in Figure 4 the glass will be thoroughly cleaned as it is raised and lowered. This arrangement therefore provides a window that is self cleaning, that may be raised and lowered with very little eifort, that may readily be locked in any position, that provides ideal circulation as it always opens from the top, and is absolutely noiseless as the glass is the only moving part and that is held between felt, or other similar material. There is therefore no metal contact to cause a rattle by the wind or other means for causing vibration. The window is also completely sealed so that with the window closed all outside noise is eliminated.
