HAT OR THE LI KE.
SEECIFIQATIOII forming part of Letters Patent No. 735,790, dated August 11, 1903. Application filed September 29, 1902. $eri-al No. 125,296. (No model.)
T 00% whom it may concern:
Beit known that I, SYUD I-Iozoon MEERZA, a subject of the King of Great Britain, residing at 34 Oolville Square Mansions, Talbot road, Bayswater, London, England, have in- Vented new and useful Improvements in and Relating to Hats or the Like, of which the following is a specification. v
This invention has reference to improvements in and relating to hats and the like,
I the object being to provide means for ventimaking reference to the accompanying drawing, which represents a sectional side view of a helmet, but-I do not confine its use to helmets. I make the helmet or the like with an inner wall a and an outer one I), so as to provide an intervening air -space a. The walls a and b are connected by a closing-ring d; but the upper part of the inner wall a is open, as at e. WVithin the helmet or like I provide a fan f, preferably a centrifugal one, which is attached to the helmet in any suitable manner. The fan f draws its supply of air from the usual ventilator g or from a specially-provided one or from several ventilators. The air drawn in by the fan f is directed through the open top e of the inner wall to the head of the wearer and is also circulated between the walls aand b and forced out through openings h, pipes 1 or tubesj, provided in or attached to the closure-ring cl of the air-space 6. hen tubesj are used,tl1eymay be pushed small wheel having cups around its periphery-:5-
into which air is blown from a bulb 7c and led to the fan by a tube Z.
As already mentioned, although the invention is only shown as applied to a helmet,
nevertheless I do not confine it to that'one use, but may apply it to any other head-gear or the like.
What I claim as my invention, and desire to secure by Letters Patent, is-
In helmets having an outer wall and an open-topped inner wall separated therefrom, means for retaining the said walls relatively to each other and having a ventilating-fan attached to the interior of the said helmet between said walls, and pneumatic means for operating the said fan, substantially as hereinbefore described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
SYUD I-IOZOOR MEERZA.
