To all 'whom it may concern:
MALCOLM IIARD and` BLOWER COMPANY, or
VENTILATOR.
Specification of Letters Patent. Application filed Api-i161 1907. Serial No. 366.835.
Be it known that we, EDWARD 'CoNEY, a citizen ot the United 'States and a subject of Athe King of Great Britain and Ireland, respectively residing at Cleveland, inthe County of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Ventilators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.
The object of this invention is to provide in a very simple and eilicient form a ventilator for roofs, ada ted to be easily opened and closed and at a l times protect the opening from ,rain and snow, and when closed make a very tight connection.
The ventilator is illustrated in the drawings herein, and hereinafter more fully described.
In the drawings, Figure 1 is a vertical centrai section of the ventilator. Fig. 2 is a horizontal section on the line 2-2 of Fig. 1.
The ventilator shown in the drawings is made largely of sheet metal.
Referring to the parts by reference characters, A may be taken as representing the line B is a vertical drum passingy through the roof and defining lthe ventilator opening.
C is a conical shaped shedding member extending diagonally downward iroln near the upper portion of the drum to the surface of the root,` The drum is provided with a still'- ening bead l) and the member C starts from 'ust above this bead. The member C may e provided with a stifiening bead c.
Secured at intervals to the shedding member C are upwardly extending legs or straps D formed as shown. These straps are bent 5 inward at'their lower ends and riveted to the l vond the line of member C. They then extend outwardly and then vertically horizontally and finally are turned upwardly diagonally. Secured to the uppermost inclined portion of the legs is the conical member E forming a roof for the ventilator. This member extends outwardly to a oint be the drum wall. -T lis memer E is provided with an upwardly pressed annular stiil'ening bead ewlnch is preferably just above the ends d rectly over the drum wall.
Surrounding the vertical ortion d of the legs is the vertical drum or shield F which is at d, and then inwardly of the straps and is di- CLEVELAND, oruo, A CCEPCRATICN or OHIO.

open above and below. This member may be strengthened by annular stilening beads f which are preferably located just above and `just below the vertical portions d of the legs.
This shield rotects the opening at the upper end of the i rum B from rain or snow, and at the same time allows a large draft space out of the top ot the drum and upwardly between the u per cone E and the shield F, and downward y between the shield and the shedding surface (JX-this being indicated by arrows in the drawing.
At the peak of the cone E may be secured a small conical ornamental member G. Depending from this peak is a vertical rod II which is secured at the peak. At its lower end, this rod is secured to a cross bar J extending roni one side ofthe drumto .the other. Slidable on' this rod II is the sleevel K to `which is secured an inner cone L which forms a cover or gate for the drum. This cone is braced by an under cone N Secured to the member L and to the sleeve K near its lower end. A still'ening bead 1 formed in the cone L near its edge is adapted to snugly fit over the upper end of' the drum B. This inner cone may thus forni a tight cover for the ventilator drum, closing the ventilator. On the other hand, the cone may be clevated'to nest beneath the cone E, opening the ventilator. In this open position, the bead 1 occupies the recess provided by the bead e.
To raise the inner conc. to open the venti later, we provide a bar P secured to the sleeve K and depending )arallel with the rod I'I and at its lower end loosely yoking around the rod, and secured to the rod II is a bracket Q carrying a pulley over which a chain It passesV--thc lower' end of the chain being secured to the end p of the rod I. Vhen the chain R is pulled, the b'ar P is drawn upward, raising the inner cone, and opening the ventilator. At its extreme height this inner cone nests against the under side of the outer cone E, as above explained.
It will be seen from thel above description that our ventilator is simple yet rigid in construction, neat in appearance and easily operated, while providing tight closure when closed and a large draft space when openedl Having thus described our invention, we claim':
1. In a ventilator, the combination of a wall around the ventilation opening, a movable member adapted to close the upper end thereof andhav'ing a bead adapted to extend I y over the extreme upper edge of the Wall, a roof member'suitably supported some distance above the Wall, said roof. member havin a bead, which bead the bead of the movale member is adapted to occupy when the mov-v able member is elevated.
2.' In a ventilator, the combination of a ventilator roof, a vertical rod depending therefrom, a gate for closing the ventilator opening slidable up and down -on said rod, a.
`pulley carried by the rod below the gate, a ar depending from the gate below the pul- I ley, means passing over the pulley and con- 15 nected to said bar for raisin the gate, and a cross bar for supporting the ower end of said rod.
3. In a ventilator, in combination, a drum adapted to extend .through the roof, upwardly extending legs outside of the drum, a
at a point benea chain passing over said lpulley and connected at its end wlth the member yoking around the rod, whereby the chain may elevate the 30- `inner cone to open the ventilator.
In testimony whereof, we hereunto aiix our'slgnatures 1n the presence 'of two Witnesses.
