Myinvention relates to a ventilator and a; has particular reference to a type of ventilator which is adapted for use at the'ridge ofa skylight, whether the skylight is used as an entire roof of a building, such as a garage or the like, or whether it is used as a unit for admitting light through the roof of a larger building.

Another and further object of my inven 19 tion is the provision of a ventilator which y is capable of being adjusted to varying pOS1' tions so that an adequate change of air can be secured in a building without the creation of unnecessary drafts or the admission of v outside air in the form of drafts and the like Another and further Object of mymven tion is the provision of a ventilatorv which is especially constructed to allow the air in a building or roof portion of the buildlng to pass out of the building without admitting i the roof will pass out and be replaced by air below the roofportion so that a constant change of air is effected in the building without drafts. x

Another and further object of my 'invention is the provision of a skylight ventilator in which it is not necessary to move any .por-' tion of the glass forming the skylights, such as is common in the ordinary skylights now in present use and therefore mechanical devices for the lifting of these glass panelsis not necessary.

This curb portion as shown is a specially formed structure for skylightconstruction and conslstsof a baseportion 11, a riser 12,

andan upper'portion 13;which is adapted-to 1'eceive the lower edge of thepane ofgglass forming the skylight section.

Pairs of

jack bars

15, 15 are provided at each end of the buliding, the outer ends of which are mounted upon the portion 13 of the curb 10,-and rest against a hollow rectangular member designated as a whole as 16. This member 16 has a pair of end walls 17 and18 to which

strips

The cap ;28 has an annular outwardly projecting'portion 35 extending therearound with a downwardlyprojecting portion 38, 'f the portion 35u-beingsubstantially of the same angle of the projecting portions 20 and .direction and moving the arms 33,533 to a substantially vertical position softhat the cap within which a rotatably mounted shaft 39 is positioned. The bar 32 on its underside has a pair of loops 40, 40 secured thereto towhich one end of

chains

41 and 42 respectively are secured. These loops 40 are spaced a considerable distance from the rotatably mounted shaft 39 which serve the purposeof a pulley over which the chains 41 and; 42 may travel. The purpose of the

chains

41 and 42 is to enable a workman to raise or lower the ca 'a 28 as maybe desired, to insure sufficient ventilation in the building. As shown,

when the chain 41 is pulled the bar 32 is moved in a. horizontal direction to the left to assume an angular position. and:lowering' the cap 28 onto-the member 16. When 1t is -.desir-ed to raise the, cap :16, the'.lchain.42= is pulled, thus moving. the bar .32.. in opposite 28 is. lifted, thereby allowing air,;vapors and the like to pass through the member16and outrof thebuilding.

t will thus, be understood thatlthe device while practical. ;for skylight construction,

may be insertedfinany. roof construction where the. rectangular, member is placedin the-roofin placeof the usual ridge pole and .th e ventilating cap secured thereto -in.suc'h- .manner that, it:may be raised or lowered to secure proper fven-tilation depending upon :weather conditions.

H The device will remain in a wide open position orv in any intermediate. position, be tween a wide open and a closed positiori',due to the'friction of the side m'embersin the loops secured to the member-16, and'alsoto the friction of the bar 32 in the members 31 so that it'is unnecessary to provide any fastening means for chains 41 and.42.

VVhile Lhave described more or less precisely' the details of construction, I do .not wish to be understood as limiting myself -thereto, as l contemplate changes in form;

and the proportion of parts and the substitution ofequivalents as circumstances may suggest or render expedient without departing from the spirit or scope of my' invention.
