WILLIAM HENRY GARDNER, OF SUTHERLAND, SASKATCHEWAN, CANADA.

WINDOW-VENTILATOR.

Application filed October 14, 1912, Serial No. 725,607.

To all whom it may concern Be it known that I, VVILLIAM HENRY GARDNER, of the village of Fsutherland, in the Province of Saskatchewan, Canada, have invented certain new and useful Improvements in Window -Ventilatrs, of which the following is the specification.

The invention relates to a ventilator in sertible in any window frame beneath the usual top sash thereof and the object of the invention is to provide a comparatively inexpensive, durable and easily operated device which can be quickly inserted in a window frame and which will allow a room to be ventilated without having a direct draft as is usual when the under sash of a window is raised, the ventilator being constructed so that it does not exclude the light.

With the above objects in view the invention consists essentially in the arrange ment and construction of parts hereinafter more particularly described and later point ed out in the appended claims.

Figure 1 is a perspective view of the device as applied in a window frame, part of the frame being torn away to expose construction. Fig. 2 is a vertical sectional view through a frame fitted with my ventilator. Fig. 3 is a plan view of the ventilator. Fig. a is an enlarged detailed perspective View of one of the upper corners of the ventilator. Fig. 5 is an enlarged detailed vertical sectional view through a por tion of the top and inner frames showing the bolt and clamping plate.

In the drawings like characters of reference indicate corresponding parts in each figure.

1 represents the window frame of which 2 and 3 are the side members, a the upper or top cross member and 5 the sill.

6 represents the usual upper sash located in the frame between the battens 7 and supplied with the usual glass 8.

9 represents my ventilator which is inserted within the frame between the lower edge of the sash 6 and the sill 5.

The ventilator is now described in detail: 10 represents an outer substantially rectangular open frame formed in the pres ent instance from angle irons of a width which will fit snugly in between the members 2 and 3 of the window frame and between the lower edge of the sash 6 and the sill 5. A substantially rectangular horizontally disposed open top frame 14: is per- Patented Jan. 5, 1915.

Renewed May 26, 1914.. Serial No. 841,141.

manently secured to the upper edge of the outer frame and comprises in the present instance angle iron side bars 15 and 16 and angle iron end bars 17 and 18 suitably connected, the side bar 16 actually forming the upper cross member of the frame 10. 19 is a substantially rectangular inclined inner frame formed in the present instance from side angle iron bars 20 and 21 and end angle iron bars 22 and 23 suitably connect ed. This frame is fitted with a pane of glass E i and has the side bar 21 connected by hinges 25 and 26 pivotally to the lower side of the outside frame 10. Extending plates 27 ant 28 are secured to the upper side of the inner frame and are provided with suitable slots 29 receiving short permanent bolts 30 extending from the top frame 1%. The bolts are provided with wing nuts 31 so that one can swing down or open the inner frame by removing the wing nuts and allowing the plates to escape from the bolts. Although I have described a particular means for releasably fastening the inner frame to the top frame it will be understood that any other convenient device could be employed to equal advantage. 32 is a vertically disposed transparent door pivotally secured at 33 to the bottom side member of the frame 10 such door being arranged to close in against the said frame. The door is formed in the present instance from T-iror. side and end bars 84 and is fitted with a pane of glass 35.

36 is a normally horizontally d'sposed substantially rectangular transparent door pivotally secured by hinges 37 to the upper side member of the frame 10. This door is formed in the present instance from angle iron side and end members 38 suitably connected together which memlflers carry a pane of glass 39. The door is arranged to close the open center of the top frame. When closed it is received within an open side frame 40 disposed on the top frame. A cord, rope or such like fl is suitably connected to the inner side of the door 36,

which cord passes upwardly and around a suitable pulley 4-2 suspended from the cross member f of the frame. A suitable hand grip 41-3 is located on the free end of the cord. The doors and 36 are connected by two spring wires or rods ift and ett the upper ends of the wires being permanently fastened to the inner edge of the door 36 while the lower ends are pivotally secured at 45 to the upper edge of the door 32. The rods pass slidably through guide plates 46 and 47 permanently secured to the top frame 14. This arrangement is such that When one draws on the cord to raise the door 36 he also draws in the door 32 on account of the wire connection.

48 is a catch piece or dog pivotally secured to the inner side of the frame 10 at the top and arranged to catch over the upper edge of the door 32 and holds the same closed. A spiral spring 49 has the lower end thereof fastened to the free end of the dog and the upper end fastened to the adjoining side of the top door. Accordingly when one raises the top door as above described the spring 39 draws or pulls on the upper end of the dog and initially releases it from the upper edge of the door 32 thereby permitting the door to open. It is explained that during the initial opening of the top door, the spring rods bow sufficiently to allow it to partially open While the door 32 remains closed. The top door only needs to be opened sufficiently to expand the spring 49 and raise the catch at which time the door 32 will be free to open as the door 36 is raised.

lVith this device applied on a window it will be seen that the draft instead of passing in a horizontal direction through the window will be deflected upwardly passing as it does through the frame 10 and through the frame 14.

A screen can be provided with this device for excluding flies or other insects which screen would simply need to be stretched over the outer side of the frame 10.

I wish to point out that the ventilator can be used to great advantage in railroad cars where it is desirable to have a ventilator which will give an indirect ventilation and at the same time exclude cinders and dust. In most instances where the ventilator is applied the V-shaped opening appearing at the ends of the ventilator between the frame 10, 14 and 19 would not need to be closed as the side members 2 and 3 of the window will effectively close these. They can however if desired be closed by plates or panes of glass as will readily be understood.

What I claim as my invention is:

1. The combination with the side members, sill and upper sash of a window, of

, an open upright outer frame insertible between the side members the sill and the sash, a horizontally disposed open top frame car- I ried by the outer frame, an angularly disposed inner frame connecting the inner side of the top frame and the lower side of the bottom frame said inner frame carrying transparent material such as glass, an adjustable gate normally closing the opening in the top frame, a second gate pivotally secured at its lower side to the outer frame and designed to normally close the opening in said frame and means connecting the gates causing them to open and close together, as for the purpose specified.

2. The combination with the side members, sill and upper sash of a window, of an open upright outer frame insertible between the side members the sill and the sash, a horizontally disposed open top frame carried by the outer frame, an angularly disposed inner frame connecting the inner side of the top frame and the lower side of the bottom frame, said inner frame carrying transparent material such as glass, an adjustable gate normally closing the opening in the top frame, a transparent second gate having the lower side thereof hinged to the lower side of the outer frame, spring rods carried by the former gate and pivotally secured to the second gate and releasable means locking the second gate closed, as and for the purpose specified.

3. The combination with the side members, sill and upper sash of a window, of an open substantially rectangular outer frame insertible between the side members sill and sash an open substantially rectangular inwardly extending top frame secured to the upper side of the outer frame, an inclined substantially rectangular open inner frame pivotally secured to the lower side of the outer frame, a transparent material closing the opening in the inner frame, means securing the upper side of the inner frame releasably to the inner side of the top frame, a substantially rectangular transparent horizontally disposed top gate pivotally secured to the outer side of the top frame and normally closing the opening in said frame, a vertically disposed substantially rectangular transparent gate having the lower side pivotally secured to the lower side of the outer frame and designed to normally close the opening in said outer frame, spring rods connecting the inner side of the top gate with the upper side of the vertically disposed gate, guide plates carried by the top frame and receivingthe rods slidably, a dog pivotally secured to the outer frame centrally at the top and normally holding the vertically disposed gate closed, a spiral spring connecting the dog with the top gate and means for raising or opening the top gate, as for the purpose specified.

Signed at Winnipeg this 21st day of June 1912.
