Patented July 8, 1930 UNITED STATES HUGE W. HARRIS, OF CHICAGO, ILLINOIS VENTILATING UNIT Application filed September 21, 1928. Serial No. 307,519.
This invention relates to ventilating units adapted to be installed in a kitchen window or analogous location to ventilate the room.
The object of the invention is to provide a construction which while much cheaper to manufacture than any of the units now on the market, shall be capable of being easily installed, readily adaptable to windows of varying widths, conveniently adjustable to direct the air current into or out of the room,
and also adjustable to direct the air current downwardly, into the room at an angle, if desired.
In the accompanying drawings:
Figure 1 is a vertical sectional view taken in the plane of dotted line 11 of Fig. 4, showing the unit installed in a .window and adjusted to draw air from the room.
Fig. 2 is a similar view, but showing the unit arranged to blow fresh air horizontally into the room.
Fig. 3 illustrates the unit adjusted to blow air downwardly into the room at an angle'to the horizontal.
Fig. 4 is a view taken from the left-hand side of Fig. 1.
Fig. 5 is a horizontal sectional view.
Fig. 6 is a detail view of one of the pivots.
Fig. 7 is a perspective view of a frame comprised in the unit. J
Fig. 8 is a perspective view of a pivoted panel forming part of the unit.
In the drawings, A is the window casing, B is the lower sash, and C is the upper sash. D and E are the inner stops for the lower sash B. F and G are the stops located between the paths of movement of the upper and lower sash. H and I are the outer stops for the upper sash.
The embodiment herein shown of the invention comprises a rectangular frame 1 (Fig. 7) adapted to be secured in the upper portion of the window casing, said frame being extensible so that it may fit windows of various widths. The frame 1 comprises two end sections 2, each consisting of a verticallyextending portion 3 and two'parallel horizontal portions 4. The frame further 6,'the edges of which are folded to form comprises upper and lower side pieces 5 and 14, the latter having its upper and lower 1 edges flanged, as at 15, to receive the angular edges of the end sections 13. On the end sections 13 are vertical flanges 16 having bearing openings 17 therein whereby the panel may be pivotally mounted upon pivots 18 on the inner sides of the end section 2 of the frame 1. As shown in Fig. 6, the pivots .18 are screw-threaded to receive nuts 19. For
convenience in turning the nuts 19 on and off the screws 18, said nuts are made of suflicient length to be grasped by the fingers and are provided at their inner ends with screwdriver slots 20.
An electric fan 21 is carried by the panel 12, there being a central opening 22 in the ganel' section 14 to receive the fan guard 23.
aid guard may be permanently secured to the section 14 in any suitable way. Current is conveyed to the fan 21 by means of a cord 24 which extends through a notch 25 in the inner edge of the upright portion 3 of one of the end sections 2, said notch being located at one of the corners of the frame 1. At the inner edge of the frame member 5 and upon the lower side thereof is located a rubber stop 26 against which the pivoted panel 12 is normally held by the weight of the overhanging motor.
As shown in Figs. 1 and 2, the panel 12 may be rotated through approximately 180 so as to direct the air current either into or out of the room and may also be laced in tilted position, as illustrated in ig. 3, in order to direct the air downwardly into the room. To facilitate the pivotal adjustment of the panel 12, means of any desired nature may be provided, as, for example, a hand rod 27 pivoted at its upper end to one of the and sections 13 and extending into convenient reach 'of the operator. The lower end of the rod 27 may be provided with a ring-shaped handle 28 which ma be engaged w1th a projection (not shown; on the window casing to hold the panel 12 tilted at-the desired an le.
e ventilatin unit just described is installed in the fo owing manner: The frame 1 havin been extended to approximately the proper ength is laced within the upper (portion of the window casing and secure by means of the screw 7 The operator 1s then free to use both hands to move the-end sections 2 into contact with the stops G and secure said sections in place by means of screws 8, 9, 10 and 11. It Wlll be seen that the frame 1 may thus be installed by one person, the screw 7 serving to suspend the frame while the operator completes the operation of extending and securing it in position. After the frame 1 has been mounted in the window casing, the panel 12 having the electric fan 21 permanently secured thereto 1s placed within the frame 1 and extended so as to pass the bearings 17 over the pivots 18. The nuts 19 are then turned upon the pivots so as to revent accidental detachment of the panel from the frame. The cord 24 is then placed in the notch 25.
When the ventilating unit is not in use, the upper sash C may occupy its ordinary positlon. When the fan is to be operated, the sash C is lowered, whereupon the panel 12 may be swung into position to direct the air current as desired. It will be noted that the panel 12 may be swung through 180 without interfering with a screen located at the outer side of the stops H and I.
The cord 24 does not interfere with the pivotal movement of the panel, as the notch 25 is in the vertical plane of the pivots 18 and the stop 26.
In operation the device is free from objectional vibration or noise.
It will be evident that the Ventilating unit herein disclosed is of simple and inexpensive construction and ma be quickly installed in windows of varym widths, no skilled labor being required in 1ts installation.
