- My invention relates to exhaust ventilators, and involves improved features of construction and operation.
- My invention comprises a body part which is subdivided into a plurality of parallel ducts or flues.
- This body is encircled by other parallel ducts or flues open at their upper ends and open laterally at their lower ends.
- deflector plates are attached which deflect the wind upwardly through the outer ducts or iiues and against the air or wind that is blowing transversely across the upper ends of the ducts or flues that sub-divide the body of the ventilator.
- the upward currents of air through these outer ducts serve to lift or push away the transverse wind or currents of air from the upper ends of the interior ducts, thus creating a partial vacuum at the outlet ends of these ducts which must be filled by air from the building or space to be ventilated.
- the principal object in sub-dividing the body into a plurality of ducts is to make the induction action stronger than would be the case were the body not so divided.
- the presence of the interior dividing walls prevents the surrounding outside air from creeping in over the top of the lee side of the ventilator to fill the partial vacuum created at the outlet ends of the interior ducts or lues next to the wind side. Therefore the induction action upward through the body is greatly increased.

THOMAS I-I. GARLAND, OF CHICAGO, ILLINOIS.
VENTILATOR FOR BUILDINGS AND CHIMNEY-TOPS.
Specification of Letters Patent.
Patented Oct. 24, 1911.
Application filed May 22, 19117. Serial No. 628,756.
To all whom it may concern:
Be it known that I, THOMAS H. GARLAND, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Ventilators for Buildings and Chimney-Tops, of which the following is a specification.
My invention relates to exhaust ventilators, and involves improved features of construction and operation.
Among the important objects of my invention are to provide an improved form of ventilator which not only forms a free opening for the passage of air from a building or space to be ventilated, but is so constructed that outside currents of air striking or blowing against it will produce an inductive action causing a strong exhaust of air from the interior of the building to the outside.
My invention comprises a body part which is subdivided into a plurality of parallel ducts or flues. This body is encircled by other parallel ducts or flues open at their upper ends and open laterally at their lower ends. At the lower ends deflector plates are attached which deflect the wind upwardly through the outer ducts or iiues and against the air or wind that is blowing transversely across the upper ends of the ducts or flues that sub-divide the body of the ventilator. The upward currents of air through these outer ducts serve to lift or push away the transverse wind or currents of air from the upper ends of the interior ducts, thus creating a partial vacuum at the outlet ends of these ducts which must be filled by air from the building or space to be ventilated. The principal object in sub-dividing the body into a plurality of ducts is to make the induction action stronger than would be the case were the body not so divided. The presence of the interior dividing walls prevents the surrounding outside air from creeping in over the top of the lee side of the ventilator to fill the partial vacuum created at the outlet ends of the interior ducts or lues next to the wind side. Therefore the induction action upward through the body is greatly increased.
My invention will be clearly understood by reference to the accompanying drawing, in which- Figure 1 is a perspective view of the top with a section of the outer surroundingV band broken away, Fig. 2 is a vertical sectional view, and Fig. 3 is a sectional view taken on plane 3 3, Fig. 2.
The body part B comprises side walls 5 connected by intersecting intermediate walls 6 and 7 whereby the body part passageway is subdivided into a plurality of vertical ducts or ilues 8. Extending laterally from the upper part of the bodywalls 5 are extension walls 9 whose lower ends 9 are tapered upwardly, as shown in Figs. 1 and 2, and against the lower edges of these extension walls a deiiector plate 10 is applied. Surrounding these walls 9 is a band 11, this band, together with the walls 9, forming the external passageways or ducts 12. The deiiector plate 10 closes the lower ends of the ducts 12, and the band l1 terminates a distance short of this plate so as to leave lateral entrance passageways 13 at the lower end of and into the lower parts of the ducts 12. Some of the outer walls, as the walls 9a, are continued upwardly beyond the body part and carry the conical hood 14: which serves.
to prevent rain, snow and downward air currents from entering the ducts.
In practice, the ventilator is applied to roofs of buildings or to a chimney or stack with the lower end of the body part engaging the chimney or stack end to form a continuation thereof. The outside air currents enter the lower ends of the exterior ducts 12 through the entrance 18, and by the tapered deflector plate 10 are deflected upwardly through the ducts 12, and as they are forced out of the upper ends of these ducts they encounter the wind flowing transversely across the body part outlets, and this wind is raised away from the body part duct outlets so that a partial vacuum is created at the upper ends of these ducts, which vacuum is effective on the body part ducts in creating inductive edect which will draw air or smoke out of the ducts, the air or smoke being then carried well above the ducts and then laterally away from the top. llhe conical top 14 extends well over the ducts, so that downward counter currents against the ducts are prevented and so that rain, snow, etc., are prevented from entering the ducts.
I do not desire to be limited to the precise construction andarrangement shown, as changes and modifications are possible which would still come within the scope of my invention, and I therefore claim the following:
1. In a ventilator, the combination of a body part sub-divided into a plurality of vertical ducts, extension walls on said body part forming vertical passageways, and outer walls coperating with said extension walls to form external vertical passageways open at the top and closed at the lower end and having lateral inlets at their lower ends.
