1 Claim.

This invention" relates to windows, such as the windows of automobiles, which are capable of being raised and lowered, and which are supported within the automobile body below the belt, or within the door body, and it has for its object, a particularly simple, efiicient, and compact means for supporting the window sash, and holding it from looseness and rattling while in both its open and closed position, and for supporting the sash so that it can be raised and lowered with lifting mechanism without binding, due to edgewise thrusts of the sash, particularly if the lift ing force is applied unevenly, or more toward one side of the sash than the other.

Another object is a particularly simple and eiiicient sash guide means which guides the sash without binding due to edgewise thrusts of the sash.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a fragmentary elevation, partly broken away, of an automobile door to which our invention is applied.

Figure 2 is a sectional view on line 22, Fig ure 1.

Figure 3 is an enlarged, sectional View on lines 33, Figure 1. v

Figure 4 is a fragmentary, vertical, sectional view of another form of one of the guides at the edge of the sash with one of the tail pieces therein.

Figure 5 is an enlarged sectional view on line 55, Figure 4.

I designates the supporting body, here illustrated as the hollow body of an automobile door. 2 designates the sash, which preferably has a marginal frame consisting of top and bottom rails 3 and 4 and stiles 5. The sash is guided by means located wholly within the door body I, and this means includes a guide located in the door body between the vertical lines of the stiles 5 and preferably about midway between such lines. The sash is provided with a carriage depending from the intermediate part of its bottom rail and movable along the guide, the carriage being offset from the plane of the sash, or out of the path of the sash. The carriage and the guide are provided with coacting means for holding the sash from edgewise movement and also from movement in a direction at an angle to the plane of the sash.

6 designates the guide which is here shown as in the form of opposing channels, these channels being formed up from the opposite marginal portions of a base 1. The guide is secured in the door in any suitable manner, it being generally secured to cross frame members 8 by screws 9 passing through the base 1.

l0 designates the carriage which depends from m the bottom rail 4 of the sash. It is connected to the bottom rail by a curved bracket ii so that the carriage is offset from the plane of the sash. The side margins of the carriage extend into the channels and are provided with anti-friction means as a pair of spaced apart rollers l2 at each side edge. The carriage l0 and guide 6 form the subject matter of our application Sr. No. 587,948, filed January 21, 1932, of which this application is a division. Each roller is mounted on a stud i3 and has anti-friction bearings on the stud. The ends of the studs slidably engage like side walls of the channel and the margins of the carriage slidably engage the other side walls of the channels so that, by reason of this engagement, the sash is held from vibrating in a direction .at an angle to its plane. One pair of rollers run on the bottom of one channel, and the other pair along a spring pressed track 45 extending substantially parallel to the bottom of the other channel. The spring pressed track provides means for holding the sash from edgewise movement, or vibration. Usually in sashes used in automobile construction, the sashes are guided wholly at their side margins or by vertical extensions, or tail pieces, as 20 of the stiles running in channels, or along guides-as 2| within the door or automobile body. Each of the channels, or guides 2!, is provided with a spring pressed track I! along one side thereof, and the extensions 20 are provided with projections 22 on opposite sides thereof, the projections on one side slidably engaging the track, and those on the other side, the side wall of the channel opposed to the track. Each extension is preferably a channel, and the projections are struck from the side flanges of the channel, and are in the form of straps, or loops, formed by slitting the side wall of the channel, and then bulging the straps outward, leaving their ends joined to the side wall. The extensions 20 serve to firmly support the sash when closed.

However, in constructions where the guide 6 and carriage H1 is not used, edgewise movement or play may be prevented by forming the tail pieces I! with resilient or spring pressed projections from a wall thereof, as the bottom wall of the channel formation of the tail pieces I! engaging the bottom of the guide channel 2|.

As seen in Figures land 5, the guides 2| may be unprovided with the spring pressed tracks and the extensions 20 of the stiles provided with spring pressed shoes thrusting against the inner faces of the side walls of the channels 2|. The shoes are preferably arranged in pairs spaced apart along the extension 20.

30 designates the shoes pressed by springs 3| located in the channel of the extensions and arranged to press the shoes outward, the shoes being interlocked with the extensions to hold them from displacement. As shown, each shoe consists of a base plate 32 on the inner side of the channel and having a projection 33 extending through a hole 34 in the side flange of the channel of the extension so as to engage the .side flanges of the channel shaped guide 2|. The shoes are fibre faced and preferably, the entire shoe is a fibre block. The springs 3| are coiled springs, and each seats at one end around a projection 35. The projection 35 is here shown as a pin having a collar 36 thrusting against the inner face of the side flange of the guide 2| and having a guide pin 31 extending in a perforation in said side flange. The projections 35 holds the springs from displacement. This construction of guide means for the sash is especially simple, practical and economical.

As seen in Figure 3, thebottom of the'channel members 2| may be provided with one or more resilient projections or loops 22 struck therefrom to center the sash in a Widthwise direction and hold it from rattling or looseness in a widthwise direction. Or, as seen in Figure 4, instead of the resilient loops 22, the projections may be in the form of shoes 3|) extending through. openings in the bottom of the channel shaped member I1 and engaging the bottom of the channel shaped guide 2|. In this construction, the springs 3| are interposed between the shoes and a cross piece in the channel I! serving as an abutment for the spring.

The lifting mechanism usually consists of an arm or a pair of arms 38 operated by a suitable crank 39, the arms having rollers which work in a transverse groove 49 formed along the bottom rail. The resultant of the lifting forces of the two arms is not always parallel to the guide and hence, the sash is subject to an edgewise thrust whichcauses it to bind more or less, and when but one lift arm is used, the binding effect is more pronounced. By our invention, not only is the binding effect eliminated, but the sash is held against misalinement, either when the lifting force is applied directly to the bottom rail of the sash, or to the carriage.

What we claim is: 1

The combination of a sash guide having opposing walls, one of which is spring pressed toward the other, a sash having legs forming extensions of the stiles of the sash housed in and movable in the guide, the sash when closed being located outside of the guide while the legs are in the guide, the legs and guide operating to hold the sash from movement in a direction at an angle-to its plane, said legs being channel shaped in cross section and having projections struck therefrom at spaced apart points lengthwise of the legs for slidably engaging the opposing walls of the guide in any position of the sash and of the legs in the channel.
