l 7 Claims. 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 5 belt or within the door body; and it has for its object a particularly simple, eicient and compact means for supporting the window sash and holding it from looseness and rattling when in both its open and closed position, and for so supporting' the sash that it can be raised and lowered with lifting mechanism without binding due to edgewise thrust of the sash, particularly if the lifting force is applied unevenly or more toward one side of the sash than the other. Another object is a particularly simple and eflicient sash guide means.

lThe invention consists in thenovel 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 2 2, Figure 1.

Figure 3 is an enlarged detail view of thecarriage for the sash, the contiguous portion 4of the sash being shown and the contiguousportion of the guide being shown in section.

Figures 4 and 5 are sectional views taken respectively on lines 4-4 and 5-5, Figure 3.

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 guidelocated 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 Iand movable along the guide, the carriagel being offset from the-plane of the sash or out of the path of the sash, as seen in Figures 2 and 4. 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.

I0 designates the carriage which depends from 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 I2 at each side edge. Each roller is mounted on a stud I3 and has anti-friction bearings I4 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 I5 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 as 20 of the stiles running in channels or along guides as 2| within the door or automobile body. As

channel and then bulging the straps outward, V

leaving their ends joined to the side wall. The extensions 20 serve to rmly support the sash when closed. However, edgewise movement or play is prevented by the guide 6 and carriage Ill.

As seen in Figures .7 and 8, 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 interlockedwith the extensions to hold them from displacement. As shown, the shoes consist 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 flbre block. 'I'he springs 3| are coiled springs and each seats at one end around a projection 35. 'I'he projection 35 is here shownA 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. l

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 40 formed -along the bottom rail. 'I'he 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 Which causes 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:

l. The combination of a supporting body, a sash movable into and out of the body, the body being provided with a guide located between the vertical lines of the side'edges of the sash and out of the plane of the sash, and the sash having an elongated carriage extending below its bottom rail in offset relation to the plane of the sash and extending below the lowermost edge' of the sash structure, and movable along the guide and coacting with the guide near the upper and lower ends thereof and thereby serving as a brace to hold the sash from edgewise movement, the carriage being formed with antifriction means coacting with the guide and spring pressed means for holding the carriage in snug engagement with the guide. i
