Application April 26, 1937, Serial No. 139,034 Renewed July 3, 1939 s claims.. (ci. sas- 99) 'I'he object of the invention is to provideimprovements in ventilators broadly, vbut more especially in ventilators which are intended for use in such places as the windows of homes and oiiices, in which a minimum obstruction of light is desired, as well as a maximum passage of air without draft.

Another object therefore is to provide a ventilator, which is primarily composed of vsections lil of transparent.material,v alternately positioned in spaced preferably parallel planes, and the neighboring edge portions of each pair of adjacent sections in the two planes, being connected low partitions are staggered, so as to break up' or partially baille the otherwise relatively direct ow of air through each partition, thereby preventing the passage of water through the ventilater, either as the result of a driving rain orv the impingement of a hose stream against the same, and in addition there being also preferably 1 30 positioned in each such partition a strip of gauze,

for the purpose of preventing the passage of insects, and minimizing-also the passage of foreign patticles in general. through the ventilator as a un l With these and other objects in'mind, the invention comprises further details of construction and operation, such as' are hereinafter described in the following description, when read in conjunction With the accompanying drawing, in 40 which Fig. 1 is a front elevation of a ventilator comprising one embodiment of the invention; Fig. 2 is a horizontal section on the line 2-2 of Fig. 1; Fig, 3 is a vertical fragmentary section on the line 3 3 of Fig. 2; Fig. 4 is a vvertical section on the line 4-4 of Fig. 3; and Fig. 5 is an enlarged fragmentary section through an end portion-of a modiedform of one o! the said partitions.

Referring to the drawing, there is shown a plurality of transparent sections I and 2 oi any suitable material, such as glass. "Cellophane", or similar cellulose derivative These sections are alternately positionedA in preferably spaced parallel planes, and it is to be understood that the term transparent is intended to apply to and anticipate all substances which pass light. rays to a greater or less degree, whether entirely or partially transparent, or merely translucent, as compared with metallic and other substances which are completely opaque to light rays. -5

Throughout the body of the improved ventilator, the neighboring edge portions of the sections of each adjacent pair over-lap slightly, said end edge portions being bound, or otherwise secured, between the over-lapping anges 3 of opposed 10 channel members, the central portions 4 of which members are spaced apart to provide in each instance a hollow, transversely extending partition, and each of said central portions being provided with series of vertically spaced apertures 5, which 16 series are staggered with respect to4 each other inthe opposed channel members. At their'normal upper and lower limits, said members are separated by spacing means` 6, through which,

and also through the adjacent end portions of a@ said members, rivets, or other form of securing means 1 extend, as shown in Fig. 3. Preferably within each of said hollow partitions is positioned a section of wire mesh or gauze 9 for the purpose of sifting air passing between the opposed series g5 of partition apertures.

A modified form of this construction is shown in Fig. 5in which the spacing means 6 are'elimihated, and instead each of the central portions 'l of said channel members is provided with an 20 inwardly directed boss 8, between which is prefif erably positionedthe adjacent endA portion of a strip of suitable wire mesh or gauze 9, -said members and said gauze being secured together by rivets, or equivalent means I0, passing through 35 said bosses and said gauze.- l

The upper and lower portions of the structure, thus described, are protected and partially surrounded by longitudinally extending channel members I I, while said last-named channel mem- 40. bers are iixedly positioned with respect to said transparent sections and intervening partitions.

. b'y brackets I2, which are secured at I3 to the channelmembers II and provided with parallel end portions Il, which in Fig. 3 are shown as 45 also being secured between adjacent end portions -of said'iirst-mentioned' channel members I, in v addition to the spacing means 6, while inFig. 5

an end portion I4, of one of said braces, is shown as being secured together with said gauze between 50 the bosses l.

The ventilator structure thus described may be considered asl complete in itself,`or may be provided, at either orboth of its opposite ends, with means for yieldingly securing it operatively with u respect to the adjacent portions of the ventilator,A

while said end members are normally maintained in outermost spaced relation with the ventilator proper, by means of suitably positioned leaf springs Il, or the like. the construction and operation of said end members and positioning springs not comprising a part of the present invention.

From the structure here illustrated, it will be apparent that depending upon the horizontal extent of the several transparent sections I and 2, the ventilator as a whole offers but a minimum obstruction to the otherwise relatively free passage of light rays, and in fact, when transparent sections are employed, the diminution or obstruction oiered to the passage of light rays is only caused by andto the relatively slight degree represented by the aggregate widths of the several hollow partitions described. Also, it will be quite obvious that, by staggering the apertures in the opposed walls of said hollow partitions, a driving rain or hose stream will be prevented from passing through said ventilator structure. On the other hand, air is relatively free to pass through such structure except that' the force of a normal breeze will be broken to such an extent as to prevent a draft being detected upon the inner side of said ventilator when operatively positioned in a window, or the like. Also, the gauze section 9, it will be noted.' effectively prevents the passage of insects, as ,well as minimizing the passage of foreign particles in general, past the' improved Ventilator as a unit.

Having thus described our invention, what we claim as new and d esire to protect by Letters Patent of the United States is:

1. A ventilator, comprising a plurality of transparent sections in spaced planes, and apertured partition members extending transversely between said planes and connecting neighboring edge portions of adjacent sections.v

2. A ventilator, comprising a plurality of transparent sections in spaced planes, and hollow partition members extending transversely between and connecting the neighboring edge portions of adjacent sections, the transversely extending walls of said partitions being provided with unaligned apertures.

3. A ventilator, comprising a plurality of transparent sections in spaced planes, hollow partition members extending between and supporting the neighboring edgevportions of adjacent sections, the transversely extending walls of said partitions being provided with unaligned apertures, and gauze sections positioned within said partition members between said apertured walls.

4. A ventilator, comprising a plurality of sections positioned in substantially parallel planes,

hollow partition members extending transversely of and connecting neighboring edge portions of adjacent sections, the walls of said members being apertured, and gauze sectionspositioned within said members between said wall apertures.

5. A ventilator, comprising a plurality of sections in staggered relation in parallel planes, and a partition connecting neighboring edge portions of said sections, said partition being formed of two oppositely directed channel members comprising telescoping laterally positioned anges, the central portions of which members are apertured and each pair of the adjacent flanges of which secure between them an edge portion of one of said sections.

6. A ventilator, comprising a plurality ,of sections in staggered relation in parallel planes, a partition connecting neighboring edge portions of said sections, said partition being formed of two oppositely directed channel members comprising telescoping laterally positioned flanges, the central portions of which members are apertured and each pair of the adjacent anges of which secure between them an edge portion ofv one of said sections, the channel members oi each pair being provided with inwardly directed bosses, and means'to secure the members of each such pair together passing through said bosses.
