Application September 7, 1939, Serial No. 293,668

4 Claims. (Cl. ISS-73) .This invention relates to improvements in bus I orcar Windows; .and more particularly to simplify the constructionand facilitate the operation of Windows especially adapted for use on buses', or Ythe like. Y

. Buses .are at present constructed of metal as far as possible with substantially rectangular openings for windows. The windows are accurately `1"r -1anuiacturedinto substantially true rectangles; but it is diiiicult to construct and maintain the window opening a true rectangle e in the `metal wall of the bus. This is objectionable in` that the Window does not properly fit into the opening, and it is either too loose causing'annoying rattling whenv the bus is in motion, or it is too'tight, making it Idiiiicult-to raise or lower the window.

It is, therefore, an object of this invention to construct and facilitate the `operation of windows by providing a movable `member against which the side edges of the window bear, the moving of the member being resisted by springs of a peculiar construction providing a uniform resisting force at all times. By means of this construction, rattling and binding of the Window is prevented, as the window engagesthe member at'all times with the 4same 'force regardless of the accuracy of the fit between the window opening and thevvindow.

A further object is to provide a window construction forv buses and the like, which prevents the entranceof water to moving parts of the window, and thus prevents binding of such parts by corrosion resulting from Water.

Another object is the provision of` a construction which. greatly decreases the cost of manufacture of windows for cars or buses.

These and other advantageous objects which will later appear, are accomplished by the simple and practical construction and arrangement of parts hereinafter described and 4exhibited in the accompanying drawings, forming part hereof, and in which:

Fig. l is an elevational view of a Window embodying the invention,

Fig. 2 is a sectional view taken on line 2--2 of Fig. 1,

Fig. 3 is a sectional view taken on line 3 3 of Fig. 1,

Fig. 4 is a perspective View of a member used in the window construction,

Fig. 5 is a perspective view of va member adapted to coact with the member shown in Fig. 4, and

Fig. 6 is a side View of a spring used in the device.

Referring to the drawings, in Fig. 1 there is shown awindow sash for la bus or the like, having a glass l, which has its side edges and upper edge bound in glazing tape 2, and positioned in a channel metal strip 3. -The side walls of the channel met-al strip 3 are bent back upon themselves to provide spaced walls 5 forming narrow channels in which Iare mounted strips of felt 6, which project beyond the bottom walls of th channel strip I3.

The portion of the channel strip 3 embracing the upper edge of the glass I is not provided with a felt strip; but is covered by a suitable capk l in order to provide a finished appearance and `prevent the entrance of fwater.

Y `The felt strips 6 bear against the bottom 8 of a Vchannel member having side wallsB. Mounted upon vthe bottom wall `8 of the channel member (SeeFigS. `l and 6') `are la plurality of spaced torsion springs I0 having legs VII which are xed to the -bottom wall `8 and legs I2 which are slidable thereon, the inward movement of said legs I2- being limited by a stop I3 projecting from the bottom wall 8.` The springs engage wall I 4 of a substantially channel casting having yan outer wall I5 and a short longitudinal partition I6 spaced therefrom, one wall 9 of `the last mentioned channel member being positioned in the space between Wall I5 and partition I6. The vva-ll I5 being on the outside of the Window, is adapted to be covered with a sheet of suitable metal veneer I1 for ornamental purposes if so desired.

It will `be noted that the wall I5 extends over the wall 5 of the channelstrip 3, and the arrangement labove described prevents water from coming in Contact with the springs Ill and other Darts of the device. It will be seen that in order for water to come into contact with springs I0 it is necessary for the water to pass -along the inner surface of wall I5 and then back again between the partition I6 and wall 9 of the channel member having the bottom 8.

The casting has lan inner wall I8 to which is attached la suitable guide plate I9 on the inside of the window. The casting I4 is secured to Ithe window casing 2l) by meansl of screws or similar means and .a water-tight seal is provided by strips of felt 2l.

Springs I0 exert substantially the same force at all times. That is, when they are in the raised position, the force of each spring is approximately ten pounds and when the spring is depressed it has been found that the force is practically the same. By using a spring of this type, a uniform pressure upon the side edges of the window is assured at all times and it facilitates the raising and lowering of the same, and compensates for any tendency towards binding. Heretofore, when springs of a different construction were used, the force exerted by the spring varied considerably and often caused binding of the window.

The channel strip 3 which preferably consists of one piece, can be readily mounted on the top and side edges of the glass I and provides a simpler structure than heretofore has been the case with windows of this type. The felt strips 6 are protected from dampness by the walls and the wall l5, so that they can slide freely at all times over the bottom wall 8 of the channel member.

Punched from the wall 8 are a plurality of tabs 22 which provide openings 23 to receive a latch for holding the window in various raised positions. The latch is operable by a handle 24 mounted upon the bottom rail 25 of the window cash.

From the above description it will be seen that there has been provided a` window construction which prevents binding at all times of the window sash during the process of being raised or lowered. Binding is prevented by maintaining a uniform pressure upon the side edges of the window sash at all times, this uniform pressure being assured by the springs IIJ which exert the same force regardless of theextent to which they may be depressed.

The channel strip 3 can be manufactured at a very low cost and can be quickly mounted upon the edges ofthe windowY glass. The amount of felt necessary isV reduced to a minimum by the structure herein described; and the felt is protected from dampness so that it will have no tendency to have abinding effect as has heretofore beenthe case in windows using other constructions with felt. The moving parts of the window construction are protected from rain and water ilo by providing a tortuous path for the water and Y,
