4 Claims.
This invention refers to ventilators and more particularly to a special type adapted to use and direct air currents to suit special situations and requirements. The objects of this invention include an arrangement for controlling incoming and outgoing air currents in their intensity; to direct them in such a manner as to eliminate draughts and currents through restricted openings adapted to unequal or erratic flow of air currents; to be arranged to provide for a glass window a flow of air currents that will tend to prevent frosting or deposition of condensation or moisture thereon; and an arrangement for keeping the air currents free of dust and lint, and yet split the air into individual currents. Other objects will become apparent as the invention is more fully set forth.
Ventilators for windows and automobile windshields of the conventional form are provided with an opening leading to the outside and passage therefrom that leads abruptly and quickly to the inside. This brings the incoming air at the same temperature approximately as that of the outside and causes draughts of intensity to flow from the ventilator. In this ventilator the air is controlled'as it enters by means of an adjustable valve door or trap, then directed through relatively long passages along the sides of the window, and then along the bottom of the window where itsegress is controlled in amount and direction in an adjustable degree.
In the drawing, which illustrates by way of ex ample, an embodiment of this invention:
Figure 1 is a front view of an automobile windshield provided with a ventilator embodying this Similar, reference characters refer to similar parts throughout the drawing. I
In the construction, I representsa conventional windshield glass secured in a frame having an upper mullion 2 that is hollowed out as indicated in Figure 3. The section indicates the formed construction with the top plate 3; the depending rear 4 having an opening 5located on the underside 6' and provided with a flat valve door 1 hingedv centrally on a rod 8. The valve trap preferably opens and closes as indicated, and has felt washers 9 and I0 provided as seats on which to close tightly and quietly. Adjacent to the valve is a recessed portion i I arranged to contain and hold the glass i; felt or other resilient material it being provided to make it tight and secure. An extending lip l3 projects from the portion i! and g provides a baflie over an opening passage It arranged in the front portion of the mullion which is provided with a front wall I5, a bottom plate l6 and lip ll as indicated. A screen l8 preferably of wire is inounted in the section to provide a no means for cleaning the air currents and breaking them up into direct and straight flowing currents.
The sides it of the frame are also hollowed into the formshown in section in Figure 5, having a box-like form with rear wall 20, an outside wall M, a channel 22 with lips 23 and 2t and an inside wall 25 with valve opening 45. A screen 261s provided as indicated, and a valve trap 21 with felt seats 28 and mounted on rod ll. An extension channel 29 is attached to provide a suitable 2 holding arrangement for the glass l, and has felt 30 as shown. In front of the lips and spaced away from same is a front plate 3! and has the bevelled walls 32 to direct the-air currents into the frame from a double entrance on both sides 25 of the window.
The bottom mullion of the frame has a construction as indicated in the sectional view Figure 4, having a channel 33 for the glass i, felt 34, a trap valve 35 mounted on rod 38 and with felt 30 seats 31, a rear wall 38, side walls 39 and a screen 40.
The top of the frame is provided with rods 4! and thumb screws 42 for securing the windshield.
in place on an automobile in a conventional man- 35 ner.
The arrows on the drawing indicate the general flow of air currents in the mullions and frame, and the mechanism 43 shows a method for opening and closing'the valve traps.
The air enters the mullion at the openings behind the plates 3i and at I1, entering the box-like sections of the mullion at the top and sides, following the direction indicated by the arrows and then passing through the valve trap openings to 45 the back of the glass I. The-valve traps control the amount of air passing'through, and their position and shape direct the air currents to the front of the glass at several points depending on the pitch of the angle they are moved to.
Theraircurrents come in through the whole length of the top mullion and the sides, but not the bottom portion of the frame. The openings for the ingress and egress of the air currents run 'the whole length of these parts. The entrance 56 disposed at different angles to each other,
- the channel and openings are so arranged that the air currents have to pass against bathe-arrangements provided by the double lips 23, 24, and l6, H to prevent rain, sleet, and snow getting through, while the screens It and 26 strain the air currents of their dust and small particles, as well as control erratic drafts that might otherwise develop. The arrangement spreads the air currents over the inside of the glass and being at the same temperature as the outside, lessens the stresses of temperature on the same. At the same time, moisture and condensation is prevented-from settling on the glass. The arrangement, while shown for automobile Windshields or windows, is also suitable for other types of windows. As the air currents pass through the inside of the frame, there is less injury done to the outside surfaces thereof. The valve traps by their form and movement are able to provide a varied system of flow of the air current as it passes out, and may force same against the glass or allow it to pass out away from it.
While but one form of the invention is indicated in the drawing, it is not desired to limit this application for patent to this particular form or in any other way otherwise than limited by the prior art, as it is appreciated that other forms of construction ,could be used, that would employ the same principles and come within the scope of the appended claims.
