WATKINSON' LII'III'IED, OF LONDGN, ENGLANIQ'ABRITISH COMPANY VENTILATING-LOUVER roe wnvnows Application filed Fe bruary 26, 1930, Serial No. 431,613, and in Great Britain March 12,1929.

This invention is for improvements in or relating to windows, and'has for its object to provide an improved construction of ventilating louver of the kind which is used in conjunction with a sliding window, being situated at that end of the path of movement fromwhich the sliding window moves when it is being opened. The louverwhichis generallysomewhat inclined to the plane of the window, overlaps part of the path of .movement of the window so that with a small amount of openingof the window, a tortuous path is provided which gives ventilation without draught. Windows "fitted with such louvers :are customarily used on vehicles, but

it will be appreciated that their use is not thus limited.

'The present invention. comprises a ventilating louver of the kind above described,

comprising a panel and supporting brackets, whereinithep-anel and its supporting brackets are independent of one another and so constructed that the supports can be mounted subsequently detachably secured to them.

According'to a'further feature of this invention, a ventilating louver .of the type described comprises two brackets which are adapted to be secured on opposite sidesofthe window frame, and which are of open angle section facing one another to 1 provide sure,

faces on each bracket to engage a'face and an edge ofthe panel respectivelywhen the panel is laid on the brackets. i

According to another feature of the invention each bracket may be provided at its outer end with an upstanding lugto constitute an abutment for the outer edge of the panel, with o-rwithout a resilient packing interposed "between the ipanel and the lug, and with or without means for maintaining said packing in compression.

When a louver according to the present inventionis-provided with a glass panel, the upper edge-may bemounted in a metal channel which is secured to the window frame,

and is so positioned as to press the panel against the resilient packing. aforesaid at the outer end ofithe brackets. f

According to a further featureof the vention, the bracket or the channel is provlded with a recess to accommodate apart of the channel or of the bracket respectively,

invention, there is provided a gutter which extends lengthwise of the panel- There will now be described with reference to the accompanying drawings, a particular, construction of ventilating, louver embody ing the above-mentioned principal features of the invention, and also certain-other novel details, it being understood, however, that this description is given merely by way of an example of the present invention.

In the drawings Figure 1 is an elevation of two adjacent louvers mounted on the side of a vehicle'with certain parts broken away, 7

Flgure 2 is a .section through a panel on the line 22of Figure 1,

Figure 3 is asectionthrough a bracket on the line8'3 of Figure 1,

Figure 4 is a perspectiveview of; a bracket,

Flgure 5 is a section similar. toFigure 2 of a modification, and

F'gurefi is an elevation partly in section-- rail 10 and thepillars 11. Thesebrackets, preferably, take the form :of sheet metal stainpings of steel, so as to ensureiadequate strength with economyin manufacture.

The bracket 12 which is situated between the two windows isof rectangularchannel section, see especially Figure 4 witha flange l3 directed outwardly from each lip of the channel. At the upper end'of the bracket, the depth of the channel is progressivelyv decreased as shown at 14 and the flanges 13 are inclined to the general plane of the body part of the channel. The sloping portion 14 of the base of the channel merges into a portion 15 which lies in the same plane as the inclined portions of the flanges, and said inclined portions are secured to the cant-rail 10 by screws 16 so that the bracket is inclined outwardly away. from the cant-rail at a suitable angle, say 1520, as shown in Figure 3. At the lower end of the bracket, the flanges 13 are extended beyond the channel portion and their end portions are turned up at right anglestothe flanges to form lugs 17. These upturned lugs are about the same length as the depth of the channel. lVhen this bracket is thus mounted on the cant-rail, the open side of the channel faces the side of the vehiole;

A further support for the bracket is provided by a screw 18 passing through it near its lower end and screwed into the pillar 11. A distance sleeve 19 surrounds the screw and constitutes an abutment against which the bracket is drawn by the screwing in of the said .screw. Preferably, a recess 20 is formed in the base of the channel of such a shape as to engage theliead of the screw 18 squarely when it is screwed in at right-angles to the plane of the pillar 11.

It will be seen that this bracket provides on each side of it a surface on the flange 13 on to which a panel 21 is laid, and a surface on the side wall 22 of the channel against which the ed of the panel 21 can abut. Also, the lug 1 provides an abutment for the lower edge of the panel, and there is provided on this abutment a resilient packing, such as a block of rubber 23, against which the panel is pressed so as to maintain the packing in compression. 1 A series of brackets of this type are provided for the various windows of the vehicle, and at the two ends the brackets are similar exce t that one flange 13 is omitted. One end brac et is shown at 24 in Figure 1.

The panels 21 are preferably of sheet glass, and the upper edge of each sheet is mounted in a metal holder which extends throughout the full ength of the sheet, any suitable packing 25 being interposed as is usual. In the construction shown in Figures 13, the holder is formed in two

separate parts

26, 27. The part 26 is shaped to provide a gutter 28 and one limb 29 of a channel to receive the upper edge of the glass panel and is secured to the cant-rail 10 by screws 43. The other part 27 is a metal strlp which is pressed out to provide the other limb 30 of said channel and a.

projection 31 which enters a recess 32 in the part 26. The part 27 of the holder is screwed on to the cant-rail 10 by screws 33, and it will be appreciated that the location of this part determines the location of the part 26 and, therefore, of the lower edge of the panel which is pressed against the resilient acking' 23. The part 26 of the channel is of such a length that it overlaps the brackets 12 but the part 27 is made in separate strips and recesses 34, see especially Figure 4, are provided in the flanges 13 of the brackets to accommodate the parts of the ends of said strips which lie in the same plane as the portion 15 of the bracket. These recesses serve to locate the holder and the panel in the desired position on the bracket when assembling the Whole device. It will be seen that interlocking engagement is provided between the bracket and the holder and also between the two parts of the holder. Further after the brackets have been mounted in place the panel can be very easily inserted in them and, moreover,it can be readily detached and replaced as is sometimes required in the case of a glass panel being broken.

In order to secure the panel in position and to enhance the appearance of the whole device, cover-plates 35 which may be nickelplated or otherwise made of pleasin ap earance, can be secured to each brac keth 'a pair of screws 36 engaging the bracket. y convenient locking means may be provided at the back of the base of the channel-porti on of the bracket, such as a locking-plate 37 the upper edge of which is held in place by a lip 38 depressed out of the channel. The cover-plates 35 may be in the form of flat plates, in the case of double-sided brackets, although preferably they are provided with an overhanging lip 39 to conceal the lower end of the bracket. Similarly, the coverplate for an end bracket, such as 24, may be provided with a side wall of triangular shape, as shown at 40 in Figure 6 and hereinafter referred to, to conceal the side of the bracket and close thegap between the bracket and the pillar 11.

Strips of packing 41 are arranged alon the side edges of the panel 21, and between t ese stri s and the strip 25 corner pieces 42 of pac in'g'are provided. In Figure 1, the packing is shown as projecting beyond the coverplates 35. This has been done in order to show the packing clearly; generally the packing will be concealed.

In the modification illustrated in Figure 5, the upper end of the panel is received in a metal channel 44 which is made in one piece comprising the gutter 28 and the two

limbs

29, 30. This channel is secured to the cantrail 10 by screws similarly to'the part 26 of the two-part channel illustrated in Figures 1-3, and it will be appreciated that suitably shaped recesses are provided in its rear Wall to accommodate the upper ends of the brackets. I

Figure 6 shows a device according to the invention applied to a door 45 of a vehicle. In this construction, the brackets 12 i are shaped and fixed in position as hereinbefore described with reference to Figures 1 4, and the upper end of the panel is mounted in a metal channel. The panel is held in position by a cover-plate which, is of ornamental cise constructional details described as they can be varied without departing from the in-' vention as defined'by the appended claims.
