DOUBLE HUNG REVERSIBLE METAL WINDOW CONSTRUCTION Filed Nov. 28, 1928 5 Sheets-Sheet 2 Mum/1 6.556 p H-rroeA/EY Patented May 27, 1930 UNITED STATES WILLIAM C. LEA, 0]? LOS ANGELES, CALIFORNIA DOUBLE-HUNG REVERSIBLE METAL WINDOW CONSTRUCTION Application filed November 28, 1928. Serial No. 322,444.

My invention relates to a so-called double hung reversible metal window construction and has as its primary object the production of a window construction of this type which embodies a fixed window frame, sliding frames mounted in the fixed window frame and reversible sash members in the sliding frames which are so constructed as to swing inwardly at one end, the opposite end remaining in the plane of the sliding frame.

It is a particular object of this invention to produce such a window construction in which the bottom frame may be raised and r the top frame lowered to positions relative with each other at which the reversing sash in the top frame may be drawn inwardly below the bottom of the bottom frame.

It is therefore a further object of this invention to produce a window construction in which the top of the fixed frame is provided with a suitable recess adapted to receive the top of the bottom sliding frame or in which a window unit having a transom is provided with a transom bar so constructed as to admit the upward passage of the bottom frame in front of the transom bar.

It is also an object of this invention to produce a window construction of the class described in which the frame and sash members consist of all metal elements, such construction being simple in its form and of such a character that it may be economically constructed and installed.

It will be apparent from the foregoing discussion and the following specification that the primary advantage of this window construction is to facilitate the cleaning of both the inner and outer surfaces of the window panes in both the top and bottom sliding frames from the inside of the room without the use of ladders, etc.

The general construction of this invention embodies sliding window frames which are mounted in a fixed window frame and which receive the so-called reversible sash members. The inner periphery of the sliding frames and the outer periphery of the sash members are so constructed as to make a storm-proof unit, and the sash member is so mounted within the sliding frame as to admit the to of the sash member to be drawn inwardly, t e bottom of the sash member remaining substantially in the same plane with the sliding frame. This admits the operation of the window Without removing screens or other obstructions which may be placed outside of the window.

It will be apparent therefore that this invention embodies a window construction which may be easily cleaned and which facilitates the ventilation of the room in which windows of this character are mounted.

The details in the construction of the invention, and further objects attendin its production, will be better understood rom the following description of the accompanying drawings in which Fig. 1 is an elevational view partly in section illustrating a preferred form of the invention and showing the windows in position which will admit the cleaning of the top sash.

More particularly describing the invention as herein illustrated, reference numeral 11 illustrates a window organization which is mounted in a wall 12 and embodies a fixed window frame 13 and top and

bottom sliding frames

13 and 13 respectively. The fixed window frame 13 comprises side members 14 which are provided with front and rear

frame receiving channels

15 and 16, respectively, a bottom sill member 17 and a top member 18.

As is best illustrated in Figs. 1 and 3 the top 18 of the fixed frame 13 is provided with a recess or channel 19 adapted to receive the top rail 20 of the top sliding frame and an extended recess 21-which is adapted to receive the top rail 22 of the bottom frame 13*. It will be noted in Fig. 1 that the recess 21 is formed'in a manner which makes the construction storm-proof relative to the channel 19 and is of such a depth that the bottom frame 13 may be raised in a position which will admit the inward movement of the top of a reversing sash which is mounted within the top frame 13 when the top frame is lowered to the position illustrated in this figure.

The top sliding frame embodies side members 23, a top rail 20 and a bottom rail 24, and the bottom sliding frame embodies side members 25, a top rail 22 and a bottom rail 26.

It will be noted from Fig. 3 that the top rail 20 of the top frame is adapted to be received within the recess or channel 19 in the fixed frame and that the top rail 22 of the bottom frame is provided with an extension 27, the lower surface of which carries a channel 28 adapted to receive an extending shoulder or baflie 29 formed upon an extension 29 on the bottom rail 24 of the top frame. This construction makes a storm-proof connection between the two sliding frames. 7

The reversing sash member used in this invention is the same for both the top and bottom sashes and the details in this construction are best illustrated in Figs. 1, 2 and 3 and 7 to 11, inclusive, wherein it will be noted that the top and bottom rails of the sliding inwardly extending flanges or

shoulders

33 and 34 and that a track or channel 35 is formed between the

flanges

33 and 34, the purpose of which will he hereinafter more fully described. A

The sash member generally indicated at 36 is t ge same for both the top and bottom window frames and comprises top and

bottom rail members

37 and 38, respectively, and

side members or stiles 39, and when in a closed position is adapted to fit snugly within the sliding frames as illustrated in Fig. 2. The top and bottom members of the sash are provided with outwardly extending

flanges

40 and 41 formed upon the inner and outer surfaces of these members and adapted to engage the flanges or

shoulders

30 and 31 upon the top and bottom members of the sliding frames. The

flanges

40 and 41 are also made of different widths, the flange 40 being of greater width than the flange 41 so that the

members

30 and 31 co-operate with

members

40 and 41 to provide a storm-proof bafile unit for the window.

Further precaution against the admission of rain or wind into the room between the sash'and the window frame is provided in the form of a lip 42 which is formed upon the bottom rail of the sash and is adapted to extend over the flange or shoulder 31 on the bottom rail of the sliding frame.

The stiles 39 of the reversing sash are provided with flanges or

shoulders

44 and 45 which co-operate with the

shoulders

33 and 34 in the manner described in connection with the baffle units on the top and

bottom members

40 and 41 and 30 and 31.

In order that the sash 36 may receive a reversing movement relative to the frame in which it is mounted, the lower portion of the sash stiles 39 are provided with downwardly extending arms 47 which are rigidly mounted upon the stiles, and the lower ends of which are pivotally mounted on sliding members generally indicated at 48.

The sliding members 48 may be in the form of simple blocks or rollers which are adapted to'be received within the channels 35 on the sliding frame side members; but a preferred construction of such sliding members is illustrated as embodying an adjustable friction unit which is best illustrated in Figs. 10 and 11. This unit comprises a channel section or casing 49, the sides of which are open forreceiving friction members 50, and the face of which is provided with a threaded aperture adapted to receive a screw 51. The inner end of the screw 51 is tapered as best illustrated in Fig. 11 and the tapered end of the screw 51 extends between two laterall movable rods 52, the outer surfaces of whic 1 engage the contact or friction members 50. It will be apparent from this construction that the inward movement of the screw 51 is effective to increase the pressure of the member 50 against the track or channel 35 within which this member travels.

It will be understood that the tract 35 may embody a portion of the metal side member on the sliding window frame, or as illustrated, this track may be a separate member which is formed of a material such as bronze, the slidin member being formed of Babbitt metal. This last mentioned construction increases the life of the organization and also adds to the smoothness with which a window may be operated.

For the purpose of su porting the upper portion of the sash 36 w en it is drawn inwardly from the sliding frame, links or lever members 55 are pivotally mounted upon the upper ends of the two side members of the sliding frame as indicated at 56. These links extend downwardly and the lower ends are pivoted at intermediate points 57 upon the stiles 39. 4

This construction as shown in Fig. 1 admits/the top of the sash to be drawn inwardly and downwardly and at the same time the bottom of the sash lies in substantially the same plane with the sliding frame. This construction admits the use of windows of this character in connection with fixed frames, the outer surfaces of which carry screens or other protective means such as rails, etc.

Fig. 4 illustrates the manner in which this invention is employed in connection with a window having a transom. In this construction the channel 19' in the top member 18 receives the upper rail of a transom 60 which is supported by a transom bar 61. The lower edge of thetransom bar receives the top rail 20 of the top frame 13 and the inner face 62 of the transom bar is so formed as to admit the upward passage of a bottom frame 13" thereby. This construction admits the top frame being lowered and the bottom frame raised into relative positions such that the top of the top sash may be drawn inwardly below the bottom of the bottom sash as described above.

In order that the sash members may be locked in closed position, a suitable locking device generally indicated at 58 is provided in the upper rail of the reversing sash and co-operates with the flanges 30 on the top rail of the sliding frame. The operation of this device will be clearly understood from the foregoing description and it will be apparent that the invention embodies a window organization which is of simple form and construction and which may be econoinically manufactured and installed.

Although I have herein described and illustrated one specific embodiment of the invention, and indicated various modifications 1t will be understood that it is not limited to the precise construction set forth but that the bottom of the window might, for instance, be hlnged or that the to rather than the bottom o the sashes mi; it be pivoted in the frame, and that the invention includes within its scope whatever changes fairly come within the spirit of the appended claims.
