Patented June I 1937 UNITED STATES WINDOW SUPPORT AND GUIDING MEANS Alfred H. Haberstump, Detroit,,Mich., assignor to The Murray Corporation of America, a corporation of Delaware Application April 22, 1935, Serial No. 17,560 6 Claims. (Cl. 296-48) This invention is a continuation in part of my co-pending application, Serial Number 693,535, filedOctober 14, 1933 and pertains to window v supporting means and particularly to the supportingfand' guiding means for a window mounted in the door of a cabriolet type of body.

It has been the practice heretofore in providing windows for doors of the cabriolet type, that is to say, for doors ending at the belt line of the body, to provide a frame about the glass having extensions at the lower side edges which act as guides and supports when the window is in raised position. The guides operate in channels at the edges of the doors and are provided with friction reducing means, such as felt, balls, wheels, spring pressed plates and the like, which not only permitthefree operation of the frame, but, being biased in'opposite directions, prevent the lateral and longitudinal tilting movement of the window.

In practicing my present invention, I made possible such a support for a window in a door of the above mentioned type which is disposed in the vicinity of the wheel housing. In view of the presence of the wheel housing in the body, the rear lower portion of the door must be cut away and for this reason the downwardly extending leg on the rear portion of the window can no longer operate at the rear door edge. To overcome this difliculty, I have ofi-set the guide at the rear edge of the Windowinwardly thereof sufiiciently to clear the cut-away portion of the door;' Matable elements, in'the nature of tracks or'similar'sliding related members, may be employed,'onesecured to the window and one to the door,'inwardl'y of the cut-away portion, to guide and support the rear edge of the window in all of its positions.

The portion of the element to be secured to the window'is braced by a casting which is fixed to thelower edge of the window frame. The casting is provided with a projection which extends upwardly over the rear edge of the frame to brace and strengthen the corner of the window. The track member is thereby rigidly secured to the window in a manner to eliminate any interference with the rail at the cut-away portion of the door. The guiding member engageable by the element on the window, is rigidly mounted within the well of the door and rigidly retains the window against tilting in any of its positions. Suitable rollers and other friction resisting means, which'may be spring biased to provide proper rigidity to the window to prevent it from tilting, maybe employed on either one, or bothof the elements, to eliminate friction and at the same time rigidly support the window for movement.

Accordingly, the main objects of my invention are: to provide a guiding and supporting element on the window of a door inwardly from the edge thereof and braced by a casting which extends between the win-dow. edge and the element; to provide a fixed guide inwardly of the rear door edge and parallel to the guiding channel at the front edge of the door, of a cross section to be engaged by an element on the window to support and guide the window in all of its positions; to provide rollers between the guiding elements on the door and window to assure an easeof travel to the window and a rigid support in all of its positions; to provide a casting which extends between the supporting elements on the window and the window frame and which projects over the rear edge of the frame to provide further strength to the assembly; and, in general, to provide a support for a window at the cut-away portion of the door which is simple in construction, economical of manufacture and positive in operation.

Other objects and features of novelty of my invention will be either specifically pointed out or will become apparent when referring, for a better understanding of my invention, to the following description taken in conjunction with the accompanying drawings, wherein:

Figure l is a broken view, partly in section and partly in elevation, of a door and window embodying features of my invention;

Fig. 2 is an enlarged broken view, partly in section and partly in elevation, of a portion of the window and its support illustrated in Fig. 1;

Fig. 3 is an enlarged sectional view of the structure illustrated in Fig. 1 taken on the line 3-3 thereof;

Fig. 4 is a sectional view of the structure illustrated in Fig. 2, taken on the line 44 thereof;

Fig. 5 is an enlarged, broken sectional view of a portion of the door illustrated in Fig. 1, showing the opposite side thereof from the portions illustrated in Fig. 2.

I have illustrated in Fig. 1, a door It) for a cabriolet type of body I I to be employed adjacent to the wheel housing of the body in such manner as to require the lower right hand corner of the door to-be cut away at I2 to mate with the wheel housing portion of the body. A window glass I3 is disposed between the inner and outer panels of the door in the conventional manner having a frame I4 thereabout for providing a support for the glass and engagement for an actuating mechanism [5 by which the window is moved to a pretrated in Figs. 2 and 5.

determined position through the operation of a handle l6. Arms on the regulator I5 are secured to a plate l8 attached to the lower portion of the frame M. The plate l8 has slots l9 therein in which headed pin 2| on the ends of the arms slide. The slots I9 are enlarged at 22 at their adjacent ends to permit the heads of the pin 2| to project therethrough for attaching and securing the frame I4 to the arms IT.

The front edge 23 of the window is extended at 24 below the frame l4 to provide a support for the front edge of the window when the win-1 dow is in raised position. This is illustrated more clearly in Fig. 5 wherein the extension 24 operates in a channel 25 provided on the .front rail of the door. The extending portion 24 is provided with pairs of rollers 26 of conventional form which are spring biased in opposite directions outwardly, to provide a resistance to a lat eral tilting movement of the window-.when .the

extension 24 is supported in the channel 25. A bracing element 21 may be employed between the extension 24 and the plate l8 to provide ri-.

gidity to the assembly in the, plane of the window. The rear edge of the window is supported in a new and novel manner to provide clearance for the operation of the window within the door relative to the cut-away portion |2 thereof. It will be readily appreciated that an extension 24 on the rear edge of the window would prevent the lowering of the window any appreciable amount in view of the interference with the cut-away portion l2 of the door. To provide adequate support for the window and have the window movable a desired amount within the door, I have utilized a guide element 3| which has mated therewith a slidable element 32 which is secured to the window frame l4.

The element 32, herein illustrated, is of channel shape, engageable with the element 3| which is of T-shape. This engagement is effected through rollers 33 which may be spring pressed to retain the elements in mated, slidable relation again'st'a' tilting movement. The element 32 is secured to the frame l4 by a casting 34 of triangular shape, one branch 35 of which is secured to the elements 32 by screws 36. Another branch 31 of the casting 34 is secured to the frame l8 by suitable means, herein illustrated as by rivets 38. Thebracket 34 has an extending flange 39 which projects upwardly over the rear endof the frame M as illustrated'more clearly in Fig. 2. The rear flange of the frame l4 has screws 4| extending therethrough for securing the frame to the casting. The casting may be more rigidly secured to the frame M by a screw 42 which extends completely across the frame H! as illus- When the frame element I8 is of sufficient strength this screw 42 may be omitted.

The casting 34 is similar to that illustrated and described in the above mentioned co-pending application and is employed for the same purpose, that of rigidly securing a guide element to, the window frame inwardly from the edge thereof. In the co-pending application, a channel is providedwhich is. of a depthequal to the distance of the guiding element from the edge of the window for the purpose of encompassing said edge and providing engaging means for said guiding element. In the present construction, the channel of extended depth is eliminated by employing a guide element interjacent the edges of the window, which is rigidly secured to the door, and which operates in a manner somewhat similar to the operation of the guide element illustrated and described in the patent to Otto F. Graebner, Number 1,939,976, issued December 19, 1933, and assigned to the assignee of the present invention.

The casting 34 materially strengthens the corner of the frame and rigidly retains the movable element 32 rigidly on the window l3. While I have shown specifically the element 3|v as being of T-shape and the element 32 as being of channel shape carrying rollers 33 in contact with the eleiment 3|, it is to be understood that other elements of channel or other shape well known in the art to be suitable may be substituted for the elements 3| and 32, illustrated, for guiding and supporting the window.

As will be evident from Fig. l, the location of the elements 3| and 32 permit the window to be lowered completely into the well of the door without interference with the metal defining the cut-away portion I2. This is effected by having one element rigidly supported inwardly of the rear door edge and parallel to the channel 25 at'the front edge of the door. The'window is provided with an element engaging means which slides thereon in a path parallel to the channel 25. The window is rigidly retained against tilting movement in, its plane as well as against a tilting movement laterally thereof through the engagement of the rollers 26 in the elements '24 on the front edge of the doors and through the engagement of the rollers 33 and the elements 3| disposed inwardly from the rear edge of the doors. The'employment of the particular casting 34 is unique in providing rigidity to the window frame and supporting the elements 32 in rigid relation thereto so as to prevent a tilting move ment or the flexing of the window due to the lack of rigidity of the elements 32 or the frame.

While I have described and illustrated but a single embodiment of my invention it will be apparent to those skilled in thejart that various changes, additions, omissions and substitutions may be made therein, particularly in substituting well known elements similar to elements 3| and 32 for the guides in the rear portion of thedoor in-v wardly to'the rear edge thereof, without'departing from the spirit and, scope of my invention, as set forth in the accompanying claims.-
