WINDOW FRAME.

application med' November 12, 1924. seria; No. 749,362.

This invention relates to improvements in vwindow frames and more particularly to window frames such as are now used exten;-A

sively in the construction of motor vehicle e bodies of the vso-called sedan or convertible typesa It is common practice to provide the doors of automobile bodies of this type with dis' appearing windows. The frames of these 1o windows in composite bodyy construction such as those employing a super-structure of wood with sheet metal outer construction are usually formed by the side rails of the door. With the advent of the so-called all-metal bodies, however, it became a problem in certain types of construction to provide a window frame which could be made up as a separate unit and applied to a door in such manner that the assembly would be possessed of the required strength and rigidity.

One object of the present invention, therefore, is to provide an improved window frame which may be made up as a separate unit and applied to an automobile door in such manner that the same will form a rigid part thereof.

Other objects and advantages relate-more particularly to the construction of the window frame per se, the manner in which it is assembled, and the means whereby the win? dow glass retaining and guiding cushions may be mounted in the frame and held therein against displacement.

Various other objects and advantages will appear from the following description taken in connection with the accompanying drawings wherein one form of the invention is illustrated.

Figures 1 and 2 are perspective views of portions of the improved window frame; Fig. 3 is an enlarged section' on line 3--3 of Fig. 5;

Fig. L tis an enlarged section on line 4-4 of Fig. 5; z

Fig. 5 is a side elevation, showing the improved window frame applied to the door of a motor vehicle body; and

Fig. 6 is an enlarged section on line 6-6 of Fig. 5.

In the drawings, the window frame has been shown mounted in conjunction with a` door of all-metal construction, but it will be readily appreciated that the invention is not limited in its usefulness to such specific application, but on the other'hand might be employed in connection with doors generally, regardless of the 4particular v construction thereof or of lthe 'material of which they are made.v l i The window frame in the present embodiment of the invention is fixed to the door and :the window pane is jslidable up and down therein.

The improved window frame is .shown combined with a s'heetmetal door 1 coinprlsmg a front panel'2 having the'side edges -3 and 4t thereof bent over the edges of sheet metal side members 5 and 6, respectively, as shown in Fig. .4, the inner portions 7 and 8 of the side members being bent inwardly for givlng greater rigidity -to the door and for providing means for attaching the vertical window frame members thereto as herein- `after explained.

The door structure per se forms no part of the present invention and is only shown and described with suiiicient )clearness to enable those skilled in the art to understand the manner in which the improved window frame may be applied to automobile doors of this type.

The vertical side members of'Jt-he frame will first be described, referring more particularly to Figs. 1, 2 and 4. Vertical melnber 9 is pressed from sheet metal and,as preferably constructed, comprises a member 10 of U-s'hape or channel shape in cross section having flanges 11 and 12, and a complementary member 13. Member 9 is placed against the inwardly'extending portion 7 of. side member 5 and secured thereto in vany suitable manner such as by soldering or spotfwelding, the member'extending downward-v ly through the greater-portion ofdoor 1 so that Ait is adequately supported thereby, the 95 member in effect being an integral and rigid part of the door. A tubular reinforcing member 14 which is rectangular in cross-section is inserted between flanges 11 and 12 and pressed against the bottom portion or web 15 of the member 10, the webV being pressedV inwardly as shown in Figs. 1 and 4- to provide a dove-tail groove 16 extending v the entire length thereof for the purpose hereinafter explained. l

The edge of liange 12 is offset and'bent to provide ahead 17 which ts a similar bead 18 pressed from member 1 3 when the latter is inserted between flange 12 and reinforcing member 14. Flange 12 has suflicient resili- 110 eney'to-permit bead 18 to snap into interlocking relation with bead 174while at the same time holding 1t securely 1n position and `against accidental displacement. The outer Aadjacent edge of the window pane 22, as

shown in Fig. 4.

The vertical member 23, as preferably constructed, is pressed from a single piece of sheet metal to form a tubular member substantially rectangular in cross section, two of the faces of said member being pressed inwardly to provide dove-tail grooves 24 and 25 similar to groove 16 formed in member 9 above described.

One side 26 of the tubular member is extended to provide a retaining flange 27 for the Lfelt strip 28, the strip being shaped to receive 011e edge of'pane 22. The edge 29 of flange 27 is bgnt inwardly at an acute angle thereto to form a lip for holding the felt strip in position. The other edge 30 of the member is bent ata right angle to side 31 thereof and secured in any suitable manner such as by soldering or spot-welding to side 26. Member 23 is secured to side 6 and the inwardly extending portion 8 thereof in any suitable manner, portion 8 extending beyond side 31 to form with flange 27 a channel for receiving felt strip 28. Flange 27 extends the entire length of member 23, whereas portion 8 of the door, of course, only extends to the top edge thereof. Some means, therefore, must be provided and arranged opposite flange 27 to form the other wall of the channel for the felt strip 28 -above the top edge of the door. For this purpose a plate 32 having the edge 33 thereof bent inwardly at an acute angle thereto, similar to edge 29 of flange 27, may be secured to the upper half of member 23, as shown in Fig. 2, the plate being provided with a dove-tail tongue 34 which fits within groove 25 to hold the plate securely to member 23.

The upper horizontal member 35, as preferably constructed, is pressed from a single piece of sheet metal to form a substantially U-shape member having flanges 36 and 37, the edges 38 and 39 of the flanges, respectively, being bent inwardly at acute angles` thereto to form lips for retaining the felt strip 40-inposition in the channel formed by the flanges, the felt strip being shaped to receive the upper edge of pane 22, as shown in Fig. 3. A U-shape reinforcing member 41 is inserted between flanges 36 and 37 and interlocked with member 35 by means of the edge 42 of member 41, this edge being bent inwardly, as shown, and forced back of the 24, respectively, the strips extending from the upper ends of the members to the top edge of door 1. The lower portion of groove 25 below the top edge of the door may.l be used for holding in place the adjacent edge of the wood panel or backing 47 which supports the actuating mechanism for the window, the lock and other accessories (not shown) which may be applied to the door,

this edge of the panel being provided witha suitable T-shape tongue to snugly fit the groove. When this lower portion of groove 25 is used for holding the adjacent edge of panel 47 in position, portion 8 is made to terminate short of the groove so that the` same is not covered thereby. The panel then forms with flange 27 the channel for receiving that portion of felt strip 28 lying below the upper edge of the door.

In placing pane 22 in operative position in the frame, a side edge thereof is inserted into the felt strip 28, as shown in Fig. 4, and felt strip 21 applied over the opposite side edge thereof. The pane is then swung inwardly about felt strip 28 as a center until strip 21 rests against flange 10 and reinforcing member 14, as shown in Fig. 4, the felt being hooked under lip 20 of vthe flange.

Member 13 is then inserted between flange 12 and member 14 and forced inwardly, flange 12 yielding sufficiently to permit bead 18 to snap under bead 17 thereof whereby member 13 interlocks with member 9 and forms with flange 10 a retaining channel for felt strip 21. Lip 19 of member 13 acts with lip 20 to hold the felt strip in position. The pane may be readily removed by removing strip 13. y

The lower edge of pane 22 may be provided with the usual connection 48 for cooperation with the actuating mechanism (not shown) for raising and lowering the pane in the manner well known in the art.

From the foregoing it will be seen that a window frame has been provided which may be built up as a separate unit and rigidly applied to an automobile door. The improved window frame also permits of ready removal of the pane should occasion arise.

While the window frame has been shown and described as a separate unit secured to the door, it will be obvious to those skilled in the art that the side edge members of pressed from sheet metal and constructed substantially in accordance with rthe resent invention, as defined bythe claims. n this case the improved window frame will be an integralpart of the'door, each side edge' member of the door and the corresponding side memberof the'frame being one and the same part.
