ITED STAES OFFIQ l WINDOW-VENTILATOR.
Specification of Letters Patent.
v Patented Feb. 22, 1916.
Application filed February 15, 1915. Serial No. 8,145.
To all whom it may concern:
Be it known that I, ROBERT GEORGE D101:- SON, asubject of the King of Great Britain, and resident of the city of Toronto, county of York, Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Window- Ventilators, described in the following specification and illustrated in the accompanying drawings, that form part of the same.
The principal objects of the invention are, to provide a ventilator for railway windows which will allow of the introduction of fresh air without discomfort to the passengers sitting close to same, and to provide means for protecting the ventilator from injury by the lowering of the inner sash thereof when it is in its open position.
The principal feature of the invention consists in the arrangement of an obstructing member adapted to extend into the path of the inner sash when the ventilator is open and to be held out of engagement with the inner sash when the ventilator is closed.
In the drawings, Figure 1 is a perspective view of a portion of a window showing the outer sash and the ventilator sash therein arranged in'the closed position; Fig. 2 is a perspective view of a portion of the window showing the ventilator opened. F ig. 3 is a vertical sectional view showing the double sash closed and the ventilator closed. Fig.4 is a vertical sectional view showing the ventilator open with the inner sash raised and held from being further lowered.
Like numerals of reference indicate corresponding parts in, each figure.
Referring to the drawings, 1 is the outer window sash arranged in the window frame 2 having an opening 3 therein closed by a window sash 4 adapted to swing inwardly.
5 is a dust screen arranged at the outer side of the opening 3 on the frame 6 surrounding the same.
7 are bellows ends arranged between the inner side of the swinging sash 4 and the screen frame 6, adapted to close the ends of the ventilator opening to prevent inflowing air from passing out the ends and creating a draft unon a person sitting close to the window. The hinged sash 4 directs the inflowing air upwardly and is held in ad-' justed positions by the pivotal ratchet arm 8 secured to the side of the main sash and inclosed in a recess 9 being adapted to swingoutwardly on the opening of the ventilator sash 4 and having a notched slot 10 therein.
11 is the inner window sash slidably arranged in the frame 2 and adapted to close down upon the sill 12.
13 is an obstructing member in the form of a pivotal dog pivotally supported upon a block 14 arranged between the guides of the inner and outer windows. This dog is provided with an upwardly turned hook member 15 adapted to extend forwardly into the path of the inner window and to engage the under edge thereof to restrict it from further downward movement.
16 is a lug projecting downwardly from the bottom end of the member 13 and adapted to be engaged by a projecting lug 17, carried on the sash 4 so that on the closing of the ventilator sash the obstructing member will be swung on its pivot to move the hook member 15 out of the path of the sash. A suitable spring 18 may be provided to cause the obstructing member to swing outwardly upon the opening of the ventilator sash but it may be so hung as to swing forward by gravity. The lug 16 moves freely in a transverse groove 19 formed in the inward side of the block 14. The obstructing member 13 is preferably arranged at each side of the window and by the use of same the safety of the ventilating device is insured, that is to say, it will be impossible to accidentally lower the inner window to a point where it will come in contact with the ventilator but if the ventilator is closed, the obstructing member will be moved out of the way and the inner window moved downwardlv without obstruction.
A ventilator for railway cars such as described is of very simple construction and cannot get out of order and affords a means of ventilating av car without risk of the bad effects of drafts upon the passangers, the slanting inner sash directing the inflowing air upwardly into the car.
What I claim as my invention is 1. In a window ventilator, the combination with the outer sash having a ventilator member adapted to extend inwardly therefrom, of an obstructing member adapted to extend into the path of movement of the L tion with'a window sash having a swinging inner sash to guard said ventilator member when in its open position from the inner sash being lowered thereon.
2. In a window ventilator, the combinaventilator sash therein and an inner sash, of an obstructing member arranged between the inner and outer sash adapted to extend into the path of movement of the inner sash upon the opening of the ventilator to prevent the downward movement of the inner sash, and means adapted to move said obstructing member on the closing of the ventilator.
3. In a window ventilator, the combination with an outer sash having an inwardly extending ventilator, and an inner sash, of an obstructing member arranged between the inner and outer sash above the ventilator sash and adapted to extend beneath the inner sash when raised upon the openingof the ventilator, and a lug projecting from I the ventilator adapted to engage said ohstructing member to withdraw it from the path of downward movement of the inner sash upon the closing of said ventilator.
4. In a window ventilator, the combination with an outer sash having an inwardly extending ventilator and an inner sash, of a pivotal obstructing member arranged between said sash and adapted to swing beneath the inner sash when ,raised and upon the opening of the ventilator, and a lug projection on the ventilator adapted to engage said pivotal member to' swing it back out of the path of the inner sash.
Signed at the city of Toronto, county of York, Province of Ontario, Canada, this 10th day of February, 1915.
