H. L. TURNER.
VENTILATOR.
APPLICATION FILED AUG. 11, 1913.
Patented June 16 Witnesses UNITED sTATEs PATENT oEEioE.
HUQH L. TURNEE, or OKLAHOMA, OKLAHOMA VENTILATOR.
Specification of Letters liatent.
Application med August 11, lea. serial No. 784,230.
To all whom t may concern Be it known that I, HUGH L. TURNER, a citizen of the United States, residing at Oklahoma city, in the county ofy Oklahoma and yState of Oklahoma, have invented a new andl useful Ventilator, of which the following is a specification. This invention relates to ventilators and more particularly to means whereby an ordinary ventilator can be automatically closed in the eventl of fire and whereby it can be.closed manually at any other time desired. f
A further object is to providea device of this character which is simple and durable4 with. the preferred form of the invention has been shown, the same being shown open. Referring to the drawing by characters of reference 1 designates the ventilator shaft' 4and 2 designates the ventilator which may be of any desired construction, r rlhe device constituting the pij'esent invention includes a frame 3 adapted to be secured in the shaft and having acentral lcross memv ber 4 to which shutters 5 are hingedly connected as at 6, these shutters being adapted,
when closed, to bear against the frame 3 and thus completely close the shaft.
A hanger 7 is suspended from the `center of the top of the ventilator and carries a sheave block- 8 through which extend chains 9. Two of these chains are employed, the chains extending inopposite directions through the block and being attached to a coupling 10. The said chains are extended to the respective shutters 5, being attached `thereto near those edges thereof -remote from the hinges 6. The other ends-of the chains are attached to the coupling 10 and this coupling, in turn, is attached to` a single actuating chain 11 which extends downwardly through an opening 12 in the cross Patented June 16, 1914.
member -4 and has a ring 13 secured to its lower end. Connected to this ring 13- is a chain 14 of suicient length to extend to a point4 where it can be conveniently reached and a weight 15 is attached to the free end of the chain 14. When this weight is placed on a bracket 16 or otherstructure, the shutters 5 are permitted to gravitate downwardly to open position, as [shown in the-drawing. When, however, the weight is removed from its support 16, it will pull on chain 14 and,
through ains 9, upon the shutters, thus movingthe shutters to closed positions. An-
. other chain 17 is attached to ring 13 and has a weight 18 secured thereto, this chain being held normallyl slack by a fusible link 19 preferably attached to one wall of the ventilator shaft 1. This chain 17 will n0t,'vordi nai-ily, interfere with the opening and closing of the shutters 5. Should it be desired to close the shutters,
-it is, merely necessary to remove the weight` 15 vfrom .the support 16, whereupon said weight will operate the shutters i'n the manner hereinbefore described. To open the shutters the weight is placed on its support Aas hereinbefore described.` If, while the weight 1.5 is supported, a i'ire should occur in the ventilated structure, the link 19 would melt, thus releasing weight 18 and causing sov the said weight to drop and pull through chain 17 on chain 11, thus closing the shut' ters 5 independently of the shifting. of
(weight 15.
- VWhat is claiined is i `The combination with a ventilator shaft and a cross bar mounted therein and provided with an opening, of oppositely disposed shutters hingedly 'connected to the cross bar and adapted, when raised, to close the spaces at opposite sides of the cross bar, a guide device' supported above the bar, a vflexible element extending upwardly through tne opening of the bar, connections between said `elements and the respective shutters, said connections being extended opposite directions over the guide device and downwardly to the respective shutters whereby,
when the flexible element is drawndownwardly, the oppositely extending. shutters will be raised simultaneously, a weight con'- nected tosaid flexible element and adapted,`
when released, to pull downwardly thereon, In testimony that I claim the foregoing as thereby to raise the shutters simultaneously my own, I have hereto eixed my signature to closed positions, and a fusible link eonin the presence of two witnesses. neeting said weight to a Wall of the ventila- HUGH L. TURNER.. s tor and normally `supporting the Weight in Witnesses:
