VENTILATOR.
Specification of Letters Patent. Patented Feb, 21, 1922 Application 'filed November 1, 1920. Serial No. 421,079. 7
To all whom it may concern:
Be it known that I, THOMAS CHARLES I CRoUcH, a subject of the King of Great Britain, and resident of Elbow, in the Province of Saskatchewan, Dominion of Canada, have invented certain new and useful Imrovements in Ventilators, of which the folowing is a specification.
This invention relates to improvements in ventilators particularly designed for buildings, either public or private, and the objects of the invention are to provide such a device as will permit free and full circulation of fresh air without the creation of any draught.
Further objects are to provide a ventilator which is rain proof, storm proof and dust proof, but may be used at all times, of the year regardless of atmospheric conditions.
Further objects are to provide a ventilator of simple construction, inexpensively designed and which may be manufactured of few parts and designed to better perform the functions required of them.
The invention consists essentiallyv of the improved construction hereinafter described in detail in the accompanying specification and drawings.
in the drawings:
Figure 1 is an elevation of a window embodying the present invention.
Figure 2 is a vertical sectional view.
Figure 3 is a horizontal view.
Figure 4; is a perspective view of the frame supporting the screen. 7
Figure 5 is a perspective view of the two parts of one of the screens.
Like characters of reference indicate corresponding parts in all the figures.
Referring to the drawings; A represents the window frame and B the sash, C indicates the upper, and D the lower frame for supporting the screens of my improved ventilator. The ventilator comprises a plurality of spaced extensible screens, E, F and G, the three screens being shown in the present embodiment, which screens are held in the upper and lower frames C and D, the said frames each including side flanges 10 adapted to retain the screens in position.
Each screen is laterally extensible and may be of the usual form comprising two rectangular frames 11 and 12 having a slidmg connectlon with each other by means of a tongue 13 on one section entering a groove 14 on the other section in these screens, and spaced a short distance apart, and are of fine mesh, the two outer screens being preferably of mesh, while the inner mesh is somewhat finer, say mesh.
The frames C and D containing the screens are designed to be placed in positlon in the top or bottom of the sash B and are conveniently held in position by retaining means such as the bracket 15 which is hinged to the frame A and provided with a turned end and having thumb screws 16 designed to engage the innermost screen G.
It will be seen that the creation of any draught is prevented by the fact that-each screen acts as a ventilator'to the air current, breaking it up and deflecting itfrom one to the other so that the current of air will have no fouls after leaving the ventilater. A plurality of screens are also present which prevents rain or dust entering.
As many changes could be made in the above construction and many apparently widely different embodiments of my invention within the scope of the claim constructed without departing from the spirit or scope thereof, it is intended that all mat i813 contained in the accompanying specification and drawlngs shall be lnterpreted as
