MOUNTING FOR VENTILATING-FLUES.

Application filed December 9, 1912.

To all whom it may concern:

Be it known that I, FREDERICK C. KAsoH, citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Mountings for VentilatingFlues, of which the following is a specification.

This invention has reference to mountings for ventilating lines, and the invention consists in the construction and combination of parts substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a sectional elevation of the ventilator showing the movable part-s open as in use, and Fig. 2 is a corresponding view to Fig. 1 but showing the same closed.

The ventilator as thus shown is planned to have the highest possible efiiciency compatible with its size, so that a large volume of air may pass through the same when it is fully open and at the same time be promptly extended and closed in case of fire or excessive temperature in the flue, and also to have means for purposely opening and closing the same at will. To these several ends the said device is built with a number of parts or features peculiar to itself and comprising a suitably heavy cylindrical body or tube 5 of sheet metal which, in use, sleeves in the permanent pipe or tube with which the ventilator is connected but not shown herein. The said body tube 1) may have more or less length relatively than that shown herein and becomes the immediate support for the other parts and which comprise a chamber 0 of cylindrical outline at the top which is supported from the said body 6 by suitable brackets cl of strap metal and having the upper hood h engaged therewith at their upper ends and the lower hood 7L near their middle while the shield s is secured at its upper edge in the outwardly offset portion of said brackets jointly with the upper contracted edge of lower hood h.

Certain details enter into the construc tions and arrangements which it is material to observe. Thus, the so-called draft shield s is like a skirting about the body 5 and is held apart therefrom in inclined position by the laterally bracing ends 2 of said brackets cl while the upper edge thereof extends above the edge of said body and is engaged at 3 on the said brackets and in such rela- Specification of Letters Patent.

tion to said body as to provide a gradually narrowing draft channel or space for the outside air between said body and shield and which induces a draft which discharges relatively above said body into the area over the same and draws the air in the stand pipe upward. This draft is a natural result or consequence of the arrangement of the said parts and an upward travel of the air is thus induced and maintained. The air thus put in motion finds its normal and natural discharge laterally between the two so-called hoods or shields h and h, and where the lower of said hoods serves really as a shield against air currents or drafts from beneath and facilitates the escape of the air while the hood it serves a like pur pose of protection, shield or cover from above and against rain and storm conditions.

The brackets (Z are suitably bent at their ends to make the connections at 3 and 4; with the said parts, the same bolts or rivets at said points of engagement serving to secure the chamber 0 and hood h at 4 and likewise at 3 as between the hood h and shield 8. These constructions are mentioned as the present preferred ones but they may be substituted by equivalent connections, as is obvious. Now, having the said several parts arranged and supported as shown, a free and 'sufiicient ventilating draft is obtained upward through the body 5 when said body comes into right working relations with the system beneath, and the .glass cover 9 serves as a sky-light and is suitably secured on the top of chamber wall C. However, provision needs also to be made in all such ventilating systems against fire from within the building so that the ventilator shall not become a draft passage which will stimulate fire and thus become a source of danger. To avoid or defeat such possibility in the present ventilator I employ means to positively close the same against draft the mo ment conditions become threatening or clangerous. Thus, I show three several telescopically arranged and connected rings or sections 5 of what constitute a complete closure for the ventilator as seen in Fig. 2 compared with Fig. l, where said sections are open. Two of said sections have inwardly and outwardly projecting flanges 6 and 7 respectively at their edges which engage with the other sections as shown, and in the case of the upper section with the flange 7 thereon resting upon the inwardly projecting edge 8 of the hood h. The lower of said sections comes into close fitting relations with the upper edge of the body 6 and the total elfect of said sections is to close the exit through the ventilator when lowered from position Fig. 1 to Fig. 2.

The. means for controlling or handling said sections or rings 5 comprise a cross brace or bar or spider 10 in the lower of said sections which carries a central rigid hanger 12 that has a headed projection on its lower end in which is engaged the slotted end of the controlling lever 14. The said lever is shown as pivoted at or near its middle upon a bracket 15 fixed in the body 5, and a controlling chain or cable 16 is engaged with the otherwise free end of said lever and serves to operate the same to raise the said closing sections 5. The said sections are expected to drop by gravity, so that positive means are required to hold them up and such means are provided in lever 14 and cord 16, and the said chain, rope or cable is suitably fastened to effect this result. However, provision needs to be made for fire so that the ventilator will not wait to be closed by a person but close automatically when the clegree of heat in the flue or passage approaches the danger point. To this end I provide the said cord with a fusible connec tion 18 of any well known composition and which is sufliciently sensitive to heat to melt and sever said cord at any predetermined temperature. Thus the said closure can be controlled by hand and automatically but normally it remains open.

In operation air is entrained into the direct passage through the flue from beneath and the top of the mounting being closed the draft or escape is laterally beneath the hood h and where the sections 5 are housed above and out of the way. To get the desired efl'ect in or through the said skirting or shield s the same must be arranged as shown to form a converging air passage upward and so that at the point of delivery the said passage will be narrowed as compared with its entrance, and with the upper edge of the shield at a higher elevation than the upper edge of the body I).

What I claim is:

1. A mounting for ventilators having a body and an exhaust above the same and means about the said body to entrain air into the passage through said body having inclined shields top and bottom to protect I said exhaust and a chamber at its top, in combination with a series of rings supported in said chamber in telescopic relation and adapted to drop and close said exhaust.

2. A mounting for ventilators having a chamber in its top closed across its top and side and an air exhaust opening next beneath said chamber at the side, in combina tion with a series of telescopically related rings adapted to drop and close said exhaust, and means to support said rings in said chamber.

3. A mounting for ventilators closed across its top and having an exhaust for the air about its side, in combination with a series of telescopically connected rings collapsed in said top above said exhaust and means to raise and lower saidrings consisting of a hanger connected centrally with the lower of said rings, a lever engaging said hanger and means to control said lever.

4:. A mounting for ventilators, having a chambered top and an exhaust at its side beneath said top, in combination with a series of rings in said top slidably related one with the other and adapted to drop and close said exhaust.

5. A mounting for ventilators having a chambered top and an exhaust at its side beneath said top, in combination with a series of rings telescopically related and adapted to drop and close said exhaust, a body on which the lower of said rings is adapted to seat and means on said mounting to engage the upper of said rings about its upper edge and suspend said rings over said body.

6. A mounting for ventilators having a chamber in its upper portion closed across its top and a side exit for the air beneath said chamber, and a body from which said chamber is supported, in combination with a telescopically constructed closure for said exit suspended from within said chamber and adapted to engage said body, and means to support said closure in said chamber comprising a flexible connection havmg a fuslble link withm the air passage through said body.
