VENTILATOR CONSTRUCTION Filed Feb. 20, 1951 2 Sheets-Sheet 2 Patented Oct. 11, 1932 UITED ST TES AT ream f FRANCIS A. MESKER, OF ST. LOUIS, MISSOURI, ASSIGNOR TO MESKER BROTHERS IRON COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF MISSOURI VENTILATOR CONSTRUCTION Application filed February ZO, 1931. Serial lt'o. 517,152.

This invention relates generally to new and useful improvements in ventilator construction and more particularly to cup pivotal de- 7 vices for mounting ,the swinging ventilators lo' member having an annular flange and stationarily secured on the ventilator j amb and a cup member fixed to the stile of the ventllator and engaging the peripheral face of said fixed member, thereby providing pivotal labearings for said ventilator which are of rugged construction and provide ample hearing surface. 7

Other objects of the invention are to provide a sash having framework of wrought iron goand a swinging ventilator mounted in said sashby means of cup pivots having their axes disposed horizontally, the stiles of said ventilators and the ventilator jambs ofsaid sash being formed with oppositely projecting latza'eral flanges cooperating with each other to provide an eflicient seal for excluding water and dust when said ventilator occupies closed position and the movable parts of said cup pivots being formed with projecting portions ao'which are adapted to form a lap joint with the adjacent surfaces to form water and dustexcluding oint therewith.

Further objects of the inventionare to provide a cup pivot for swinging closure mem- "-bers, said cup pivot comprising a fixed member having an annular flange to provide a peripheral bearing surface and a cup member adapted to be fixed to the stileof the swinging closure member and having an annular flange ao for operatively engaging and enclosing the peripheral face of the fixed member, thereby swingingly supporting the ventilator in position, said cup member being provided on its periphery with a lip overhanging the upper "end of the lateral flange of the lower half of the ventilator frame so as to provide a water shed therefor, said cup member being further provided on its peripheral face with an outwardly projecting shoulder spaced from said lip and. adapted to engage the lower end of the lateral flange of the upper half of the jamb soas to form a'seal therewith for preventing Water and dust from passing therethrough.

Additional objects'of the inventionare to.

improve upon the construction of cup pivots.

. for use in connection with swinging ventilators so as to provide ample bearing surface between the fixed and the movable members of said pivot and to insure efficient support of the ventilator andpermiteifective seal between the movable cup pivot member and the parts with which the latter is associated.

vVith these and other objects in view, my invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed, and. illustrated in the accompanying drawings, in which Figure 1 is an external elevational View of i1 window equipped with my improved ventiator.

The improved cup pivot construction herein disclosed is designed for use in connection with ventilators mounted for swinging movement about a horizontal axis. The jambs, as well as the entire ventilator, are

taken formed of wrought iron bars of proper cross 1 sectional contour. Consequently it is highly desirable that the pivots be of sufficient strength to support the ventilator in an ef ficient manner and that thepivots have Sll'b?" stantialbearing surfaces to eliminate binding and permit ease of operation at all times.

T'Also the meeting lines between the pivot members and the flanges of the jambs and the stiles of the ventilator have to be so 7 ing drawings, 10 indicates a window having a central opening in which is mounted a swinging ventllator .11. This ventilator is pivotally supported by pivots 12 on a hori zontal line disposed substantially centrally of the ventilator, the upper half of the ven tilator opening inwardly, as indicated at A, and the lower half opening outwardly,'a's indicated'at B (seeFigures 1 and 6), X Y

As shown, the ventilator consists of. stiles 14, top and bottom rails 15 and 16', respectively, and a series of muntins 17. stiles 1- are L shapedin cross section havingv web portions 18 and an butwardly pr-o jecting lateral fiange:19. Each web-portion" has formed. integralltherewith. and inter V to the stile of the ventilator by rivets 37.

mediate its edges, a longitudinallydisposed flange 20, which extends inwardly or. inadirection. opposite v;to terminal flange 19. Flanges 20 permit glazing of glasssections C.

The jambs 21 of the ventilator opening are cruciform incrosssection, the web portion 22 being dis-posed parallel with and spaced from the web portion 180f the stile so that theedge of the outwardly presented flange 19 of the stile overlaps the'respective It w1ll be noted by'coniparing Fzgur s edge of the web portion 22. An angle 23' 5 is secured to theweb portion 22 of the jamb in such manner that the projecting flange 23 thereof is arranged on the opposite side and parallel with the flange 19 of the stile with the edge of said flange 23 bearing against the edge of the web portion 18 and forming a seal therewith in the samemanner 'as that effected by the flange 19 with the corresponding edgeof the web portion 22 of iamb21.

-Thus 'a'doubleseal is provided between the ventilator frame and the jambs. angle members 23 are secured to the jambs in any suitable manner, preferably by welding,as indicated at 24. 3 The cross flanges 25 .".0f jambs 21 extend in opposite directions, the

outer one forming a seat forglazing purposes and. the inner one being cut away as indi cated at 26 to provide clearance for the pivot member 12:

e and that the positions of angles an flanges 19 in the upper half A is reversed'wit respect'to the lower half E, the flanges 19 the upp'erhalf being located on theinside and the fianges23 "of angles 23 on theoutside, while in the lower half flanges 19 are located on the outside and flanges 23 on the inside. This reversal of flanges is made necessary by the swinging movement of the ventilator The V eripheral face of flange and said eriphl i l The clearance for member 27. Preferably this side of the fixed member 27 is provided with a recess 31 at the point adjacent to the cutaway portion 26 in order to provide clearance fo rtsaid cut-away portion and insure an ac- "cu'rate fit between the remaining portions of the web 22 and member 27. ,A. rivet 32 secures member 27 in position. Fixed member 27is' provided with aperipheral face 34 of suitable wi th to provide the necessarybearing surface and the movable pivot member 28 is provided with an angular. flange 35 formin'g 'a circular cavity'36 in which fits. loosely said member 27 Member 28 is fixed erably made in separate sections, the ends of "the stiles beingsecuredztogether by plates 38 which are secured to the web portions 18.01? the stiles by rivets'39 while rivets 37 secure, said plates to said web portions and to members 28. Flanges 19 of the stiles of thetwo halves terminate'at points adjacent to the eral faceis provided with a lug 4O whichfits closely against the lower end of flange 19 of theupper half. Flange 35 is provided at a poi nt substantially diametrically opposed to lug l0 witha downwardly presented extension or lip 4.1 which extends downwardly over the outer face of flange 19 of the lower half suitabl distance below the upper end of said flange. thereby forming an eflective o water shedand. seal therefor.

The outer face of flange 35 is provided in its upper half with a lug 42 which when the ventilator occupies closed position bears against the inner face offlange 23 and extends asuitable distance upwardly past the lower end thereof, as clearly shown in Figure 7 The lower half of annular flange 35 is provided at a point substantially 1 diametrically opposed to lug $2 with a lug 44 which is similar to the aforesaid lug and bears. against the inner face of flange 23 of the lower half e of the ventilator. These lugs 42 and 4d form seals between the pivot members and the flanges 23 of. the jamb, thereby preventing passage of water and dust therethrough when the ventilator occupies closed position. Thus the meeting linesbetween the movable pivot member 28 and parts of the jamb arev effec tively sealed in a simple and efficient manner. 7 The pivot members 27 and 28 are preferably 136 made of rust-resisting metal, thereby insur ing easy operation thereof and eliminating danger of binding or corrosion.

' The top rail 15 of the upper half of the' of the lower half of the ventilator issubstan tially of the same construction as the lower half of the stile, as shown in Figure 4C. In the case of top rail 15, flange 19 is disposed inwardly and presented upwardly, while in the case of lower rail 16 flange 19 is disposed outwardly and presented downwardly, the other construction of details being arranged accordingly.
