This invention relates to the construction of windows especially adapted for use on buses and cars.

In certain types of windows having sliding sec- .5 tions, such as the windows frequently used on buses, there are certain limitations placed on the overall thickness of the top and bottom stationary rails carrying the window sashes.

It is therefore the principal object of my invention to provide a construction which will meet the above requirements; that is to say, the provision of sliding window sashes which will fit in relatively narrow window frame grooves or channel spaces.

My improvements in this type of window construction will be readily understood by reference to the annexed drawings, wherein:

Figure 1 is an inside plan view of a window arrangement on one side of the rear end of a 1 bus.

Figure 2 is a fragmentary view of part of the rear portion of the window frame shown in Fig ure 1, with the portion between the lines 2-2 being broken away to show the spring construction used on the transom portion of the window.

Figure 3 is a view on the line 3-3 of Figure 1, on an enlarged scale, the view being broken apart to get the same on the sheet.

Figure 4 is a section on an enlarged scale on the line 4-4 of Figure 1.

Figure 5 is a section on an enlarged scale on the line 55 of Figure 1.

Figure 6 is a section on, an enlarged scale on the lineB-S of Figure 1, Figures 4, 5 and 6 being taken on the same plane and really forming a continiious' section on the lines 46 of Figure 1.

Figures '7 to 14, inclusive, are fragmentary views of a slidable window, out of the frame, similar to that shown at B in Figure 1, the window being curved as in Figure 1;

rectangular in shape instead of having one end,

struction shown comprises a rectangular-shaped window A and a section B, the outer end of which is curved, and a transom portion T which is held in fixed position. The portion shown in Figure 1 is connected to an adjoining section to the right through the medium of a frame member or post 1 comprising part of the bus body structure. To the post I is fastened a guide member 2 having a locking member 3 associated therewith as shown in Figure 4 for receiving the side window sash parts generally referred to by S. Since this assembly S, as shown in Figure 4, forms no part of my present invention, it need not be further described as its construction will be clear by reference to Figure 4. Likewise, the construction and assembly of the parts designated by the letter R in Figure 6 are not described as they form no part of my present invention; and the same is true of the parts represented by the letter t illustrating the construction used at the top part of the transom section T.

My present invention resides in the construction illustrated between the lines I--I of Figure 3, wherein a top frame member 4 and a ,bottom frame member 5 are provided with channel formations pointing toward each other. The sides of the channel formation for the frame member 4 are numbered 6 and I, while the sides of the channel formation of the frame member 5 are numbered 8 and 9. In the bottom of the channel formation which will be referred to as 4, there is provided a weather seal l0 which is spring-pressed downwardly by the spring member II which may be in the form of the spring 12 shown in Figure 2; or it may be a channel member held in pressing engagement with the seal Iii by a Z-shaped strip spring such as shown in Figure 4.

In the bottom of the channel 5 there is likewise positioned a weather seal l3, it being understood that the weather seals Ill and iii are of any suitable material on which the window sash rails, about to be described, slide. The window sash has an upper rail I 4 and a lower rail I 5, each rail being channel-shaped and provided with glazing means it and I! to hold the glass iii in position within the channel members. Each channel member is provided with a strip portion l9 extending away from the channel toward itsrespective weather s'eal II! or I3. The outer end of the strip I9 is bent over or formed with an arm 20 which is in engagement with the respective weather seals 10 and is, thereby forming a contact-engaging surface with these weather seals of substantial area. Stated in another way, if

the relatively narrow strip portions [9 extended directly into contact with the respective seals in and it, the sliding of the window would cause the side i of the channel member, insuring that the window rail will be continuously sealed "by the weather seal 2|, it being understood that the channels in the frame members 4 and 5 carrytwo of the windows in slidable position as indicated in Figure 5, although it is to be understood that either one or both of the sections may be made slidable.

It will be noted from the construction shown in Figure 3 that the outer side of the upper window rail extends outwardly-beyond the outer plane of the side i of the channel 4, and since only the relatively thin strip portion I9 and the weather seal 2| are positioned within the channel or groove 4, this channel or groove can [be made relatively narrow, thereby reducing the thickness of the window frame and sash. The same construction applies to the lower window rail IE, but it will be noted that the side 9 of the channel frame member 5 is shorter than the side 8 so as to allow any water which might build up in the channel 5 to run outwardly over the short side 9 of the channel, which is the outside portion of the window.

As shown in Figure 5, the window section B is provided with a handle member 22 for sliding the window; likewise, Figure 13 shows a similar handle 23 for sliding the window section. The window sash covered by Figures 7 to 14 inclusive has the

sash rails

24 and 25 made precisely the same as the sash rails It and I5 of Figure 3, but arranged in reverse order, since the window, as shown, is for an inside sash corresponding to B of Figures 1 and 5, except that the left-hand end rail member is straight instead of curved as in Figure 1.

The

slide rails

24 and 25 are provided with stop-and-

guide lugs

26 and 21 which may be of any suitable material. In passing, it will be noted from Figure 6 that the window side rails 28 are not required to have the same cross-section as the top and bottom rails l4 and I5 since the arm 20 is not necessary.

Furthermore, it will be notedirom Figures 7 to 10 inclusive, that the side rail 29 has its end 30 cut away or formed so as to enter the upper and lower window rails Hand 25, adjacent the line of the glass l8 and is held to these upper and lower rail members by rivets 3| on one side, while screws 32 are used on the opposite side, so that the side rail member 28 may be readily removed for replacing the glass.

From what has been said, it will be seen that I have provided a sliding window construction which allows a minimum thickness of window frame and sash, and yet provides a construction in which the movable portion of the window can be readily moved to open or closed position.

What I claim is:

1. In a window construction, top and bottom frame members having channel formations pointing toward each other and having weather seals located in the bottom of the channels, a window sash slidably mounted in the channels of said 'slidably mounted in the channels of said frame members, said sash having upper and lower rails each with channel-shaped portions to receive a glass pane andglazing means, and an L-shaped strip portion projecting away from the channel, the arm of the L affording a substantial bearing surface to engage said channel weather seals, and

' a'weather seal positioned between the arm, the

outer wall of the rail channel and an of a side of the frame channel.
