3 Claims.

The object of my invention is to provide a novel combined window and screen for'trailers; to provide a novel and improved metal frame for such a window; to provide a hinged mounting for the window; to provide means for holding the window in any of several different positions; to provide means whereby the screen may be entirely removed from the garnish frame if desired. It is also an object to provide novel means for making the window water and leakproof and to provide various novel details of construction.

Like characters of reference designate like parts in each of the several views.

My device has as its principal elements a window frame I, storm frame 2, garnish frame 3, and screen 4, as shown in Fig. 1. The window frame is formed from a blank having a face 5 shaped as shown in Fig. 2. The blank from which this face 5 is formed is shaped at its lower corners, as shown in Fig. 9, with a rounded corner 6 and with foldable intermediate strips 1 and la foldable along the lines 8 and 8a; and integral with strips 1 and la are the outer foldable strips 9 and 9a which are foldable along the lines l0 and Illa respectively. The intermediate strips 1 and la terminate in partially rounded partially angular ends H, and the outer strip 9 terminates in the beveled end I2 while the outer strip 9a terminates in the squared end i3, as shown in Fig. 9 to form the lower rounded corner. The upper corner of the blank is shaped as shown in Fig. 10 to provide square corners; the intermediate strips Ia. and lb being foldable along the lines 8a and 8b respectively and the outer strips 90 and 9b being foldable along the lines Illa and illb respectively to provide a square corner.

The corners of the blank from which the window frame I is formed or punched out is the shape shown in Figs. 9 and 10, the two lower corners being shaped in accordance with Fig. 9 and the two upper corners being shaped inaccordance with Fig. 10. The portions or

sections

1 and 9 and la and ligand lb and 91) respectively are formed or pressed to form a window frame of the shape shown in Figs. 2, 3, 4, and 9 with members la and lb lying parallel with the face 5 of the blank and the strips 9 and 9a and 9b being disposed at right angles to the face of the blank.

A pane of glass l5 shaped similar to the opening in the frame I and preferably having rounded corners, has its edges engaging a molded rubber welt I4 which projects over the edge of face 5.

The angle iron inner window frame member l6 (which may consist of four metal strips welded together at the ends or corners) engages'the sponge rubber weather strip Ila behind the glass pane I 5 to hold the rubber tightly against the glass pane and in contact with the molded rubber strip M, as shown in Fig. 4 tosupport the glass pane and provide a water-tight closure. The other face of the angle iron inner window frame member "5 rests against the portions 9, 9a and 9b of the window frame and has a flange I1 bent into U-shape to engage members 9, 9a. and 9b of the window frame, as shown in Fig. 4. A suitable number of screws i8a, or spot welding, secure the window frame members together.

The molded rubber welt I4 is cemented to the window light opening before the insertion of the glass pane I 5, which is also cemented to this rubber. After the glass is placed in position, the sponge rubber weather stripping Ma. is placed around all four sides of the glass, abutting against the window frame member as described.

A longitudinal central bar l9, U-shaped in cross section extends longitudinally of the center portion of the window frame and has its opposite outturned ends 20 at each end of the bar secured to the window frame by suitable means, such as bolts 2|, as shown in Figs. 1 and 4.

At one end of the window frame I provide an end hinge strip 22 which is integral with the face 5 of the window frame. Hinge strip 22 has frame extension or flange and to the trailer body; 24, as shown in Fig. 4. The storm frame 2 has an end flange or extension 25 to which the outer hinge strip 23 is welded. As shown in Fig. 1, the inner hinge strip 22 is not concentric with the outer curved hinge strip 23 and the free edge of theinner hinge strip 22 is continuously in engagement with the inner surface of the outer curved strip 23, even when the window is swung to a wide open position. Thus, the hinge elements are prevented from becoming disengaged from each other when the window is swung to an open position.

The rubber weather strip 21 is folded into U-shape and engages around the edge of the outturned flange 28 of the storm frame, the rubber thus being interposed between member 23 of the storm frame and members 10. and 1b of the window frame and between flange 28 and the body 24 of the trailer. The rubber strip 21 has an enlarged edge portion 21a, as shown in Fig. 5, which element, however, is compressed when the window is assembled. The storm frame has an in-.

turned flange 26, as shown in Fig. 4.

The garnish frame 3 comprises acentral or body portion 29 with an outturned flange 30 and an inturned flange 3|. A screen 4 is mounted in the frame 32 and seats in the garnish frame 3, resting against the inturned flange 3| of said frame, or it may be mounted on the other side of flange 3!, as in the modification shown in Fig. 8 of the drawings.

In order that the window may be adjustably secured in an open position, I provide a latch bar 33 pivotally connected by pivot 34 to the central bar 19 of the window frame and having a series of spaced notches 35 and an operating knob 36. It extends through the slot 39 in the screen and in the central bar 31 which extends longitudinally of the storm frame along its central portion and which is of U-shape in cross sections but of sumcient width to telescope over the U-shaped bar IQ of the window frame and thus center the window frame. Bar 31 has extended ends 38, as shown in Fig. 4, which are welded to opposite portions of the inturned flange 26 of the storm frame.

Lock bar 40 is aflixed by screws 43 to the central bar 31 of the storm frame. Lock bar 40 has a slot 42 aligned with the corresponding slot 39 in the screen and in bar 31 for free movement of latch bar 33. Lock bar 40 also has an outturned hook end 4i with which the latch bar may be releasably engaged.

The garnish frame may, if desired, be detachably secured to the storm frame by suitable bolts 44. The garnish frame is secured to the inside wall of the body of the trailer by screws or bolts 44.

In operation, the window frame I may be swung outwardly by pushing on knob 36 of latch bar 33, and may be secured in the desired adj weather strip 21 engaging around the flange 28 of the storm frame makes a water-tight closure and also reduces the danger of breaking the glass pane. Screen 4 seats on either side desired of the garnish frame 3 and if desired, may be taken out entirely by removing the slotted lock bar 4| and then removing the screen, either by detaching knob 36 from latch bar 33 or detaching latch bar 33 by withdrawing its pivot screw 34 and thereafter replacing these elements with the screen removed. The end extension 25 of the storm frame and the outer hinge member 23 are secured exteriorly of the body of the trailer, while the garnish frame 3 is secured to the interior of the body of the trailer by the screws or bolts 44.

The lower corners 6 of the window are rounded in order to avoid accidents to people bumping their heads on the open window, these rounded corners being formed on the window frame, as shown in Fig. 9 of the drawings.

The screen 4 is secured in its frame 32 by pressing the frame together on the screen and spot welding it. The lock bar 40 of the latch is fastened through the screen by screws 43 to the storm frame. The screen may be used either on the outside of the garnish frame, as shown in Fig. 1, or between the garnish frame and storm frame, as shown in Fig. 8.

The outer edges on both sides of the bottom of the window frame are turned down or beveled to insure proper weather seal. The corners of the window (concealed by angle-iron member II) are overlapped and spot welded for greater rigidity in this part of the window as a whole.

What I claim is:

1. A frame for trailer windows, comprising a frame having a preferably rectangular window opening rounded at the corners, and having integral intermediate strips folded over to a position substantially parallel with the face of the frame, and having right angle strips folded to a position at'right angles to the face of the frame, a glass pane, shock absorbent weather stripping for same, a shock absorbent strip seating against the inner face of the glass pane, a metal strip seating against the said shock absorbent strip, a strip engaging the right angle strips of the face of the frame, and means securing said members together.
