6 Claims.

This invention relates to improved means for raising and lowering, a window sash, and is especially adapted for use in connection with buses.

It happens many times that it is desirous for a bus driver to raise and lower the window adjacent his seat, and in order that this may be done with the least effort on the drivers part and without drawing his attention away from the path of movement of the vehicle or its operation, I have provided, as the principal object of my invention, means whereby the driver may, with one hand-the left'reach over to the window and engage my improved type of operating means without taking his eyes from the path of movement of the Vehicle and without interfering with the work being done, if any, by his right hand or his feet.

My improved type of window sash operating means will be readily understood by refernce to 20 the annexed drawing, wherein:

Figure 1 is an inside View of the window which, in the case of a bus, is on the left of the drivers seat.

Figure 2 is a vertical, sectional view through the lower part of the window sash and frame.

Figure 3 is a transverse part-sectional and 'pa'rt-elevational plan View on the line 33 of Figure 1.

Figure 4 is an enlarged View of the right-hand so lower corner of Figure 1.

In the drawing, l and 2 are window frame members having stops 3 and 1 thereon. The window frame carries a window sash, the bottom rail, 5, of which carries a weather strip 6 adapted 35 to engage the ledge I on the window frame. The

rail 5 carries a glass pane 8.

Attached to the opposite ends of the bottom rail 5 of the window sash are brackets 9 and I0, being held in position by any satisfactory means as by screws II. On each of the brackets 9 and It is respectively mounted a lever l3 and lit, the mounting being pivotal in form as shown at M so that each lever may have a rotatable motion about its pivot M. Also pivotally mounted on each of the brackets 9 and it, as by a pivot pin I5, is a catch l6 having one end H extending over its side frame member I or 2. The other end I8 of the catch member l6 extends into overlapping relationship with the end of the lever H. as clearly shown in Figures 2 and 4. A spring E9 is carried by the window sash rail 5 at opposite ends thereof and acts on its respective catch member end 58 to normally hold the catch so that the end H is in contact with its 0 Window frame member I or 2.

Each of the levers i2 and i3 is provided with a hub portion adapted to snugly fit within a tubular handle member 2! which, as will be seen from Figure 1, extends nearly the full length of the rail 5.

When it is desired to raise the window, all the operator, in the case of a bus, has to do is to move his hand over to the window and grasp the handle 2| and merely lift on the window until the ends H of the catches it slide over the inclined surfaces 22 of the stop members 3 and 4, when the spring l5 will'move them into locking position over the top part of the stops. In order to lower the window, all the operator has to do is to reach over to the window and engage the tubular handle 2! at any position along its length, without looking to see where it is, and pull downwardly thereon. This will cause the levers l2 and I3 to turn about their pivots l4 and this will oscillate the catch members I 5 about their pivots l5, releasing the engaging ends I? of the catches from the stops 3 and 4 and allowing the window to be easily pulled to closed position.

While I have shown a pair of stops 3 and 4, it is to be understood that there may be as many pairs of stops arranged along the window frame as are desired.

From what has been said, it will be readily understood that the means described for raising and lowering the window sash is highly advantageous when used on a bus, as the window may be raised and lowered with one hand without taking the operators attention away from the path of movement of the vehicle.

While I have particularly described the application of my invention to a bus window which is opened by raising the lower sash, it is equally applicable to a window which is opened by dropping the upper sash; that is to say, a window which is opened by pulling down on the bar handle. Other applications of its use will be apparent to one skilled in this art.

What I claim is:

1. An operating means for raising and lowering a window sash comprising a handle member extending across the lower part of the sash and being rotatably mounted thereon, a catch member oscillatably mounted on the window sash adjacent the end of said handle member and having one end overlapping a member of the window frame having a stop located a distance above the catch and in the path of movement thereof, a lever operatively connected to said handle extending into operative relation to the opposite end of said catch member, and means for normally holding at least the lever and catch so the latter will positively engage said frame stop when the sash is raised to catch position.

2. An operating means for raising and lowering a window sash comprising a bar type handle member extending across a greater portion of the bottom of the window sash and being rotatably mounted at its opposite ends on the sash, a catch member oscillatably mounted on the sash adjacent the opposite ends of said handle member, each catch member having one end overlapping a member of the window frame having a stop for each catch located a distance above the catches and in the path of movement thereof, a lever at each end of the handle bar and positioned in operative relation thereto, each lever extending into operative relationship with its cooperative catch, and spring means for normally holding the levers and catches so the latter will engage said stops on the frame when the window is raised by the bar handle.

3. An operating means for raising and lowering a window sash as set forth in claim 2, characterized in that the bar handle is attached to the levers so its axis is above the axis of the levers and to one side thereof, whereby downward pressure on the bar handle at any point along its length, to close the window, will easily rotate the levers and move the catches from said stops when the window is in raised position. a

4. A window-sash-operating means including a single bar type handle for both raising and lowering the window, the bar being positioned across the lower part of the window sash, a pair of levers pivoted on opposite sides of the sash and supporting said bar, a catch located at each end of the bar and being oscillatably mounted and having one end positioned in operative engagement with its lever, while the other end of each catch extends over a part of the window frame, having stops to be engaged by said catches when the window is raised by said bar handle, and spring means acting to move said catches into stop-engaging position.

5. A window-sash-operating means as set forth in claim 4, further defined in that the levers and catches are positioned in overlapping relationship in free-sliding position, while the bar handle is positioned on the levers so a downward pullon the bar, when the'window is in raised position, will rotate the lever to release the catches from said stops.

6. A window-sash-operating means including a single bar type handle for lowering and raising a window, the bar being positioned across a rail member of the window, a pair of levers pivoted on opposite sides of the sash and supporting said bar, a catch located at each end of the bar and being oscillatably mounted and having one end positioned in operative engagement with its lever, while the other end of each catch extends over a part of the window frame having stops to be engaged by said catches for holding the sash in a predetermined position, spring means for normally keeping the catches in holding position,

the window being lowered by applying a downward-acting force on the bar, thereby causing the levers to move the catches to release position allowing the window to be pulled down, while an upwardly applied force on the bar raises the
