4 Claims.

This invention relates to ventilating devices, and more specifically to new and useful improvements in a Window air vane device made of Lucite or other plastic material, that can deflect moving air through a window into a building.

It is a common experience, particularly with city dwellers, to emerge from their homes and discover for the first time that a heat wave has broken and that the temperature in the streets is considerably lower than that in the house. This occurs most frequently when a room or apartment has only one exposure, and the breeze passes by the windows without entering them,

It is therefore an object of this invention to provide a device capable of deflecting outside air currents into a room.

Another object is to provide a window air vane device that is easily installed and Operates quietly and automatically.

A further object is to form a device with a resilient control to retain a freely rotating air vane in functioning position.

Still another object is to provide a device that is strong, can be made and assembled cheaply and is attractive in appearance.

These and other objects are accomplished by forming a window air Vane device of a bracket, a vane, means to attach the vane rotatably to the bracket and control means to retain the vane resiliently in functioning position. In one form of the invention, the attaching means joining the vane and bracket consists of two bearings which permit the vane to rotate in relation to the bracket. In the other form the attaching means consist of two collars fixed to a vertical bracket rod, and two eyebolt-shaped elements rotating freely on the rod, and supported by and turning on ball bearings rolling in a race in the collars, the threaded shanks of the eyebolt elements and coacting nuts retaining the vane rotatably on the bracket.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 8 is a detailed sectional view of one of the elements of the attaching means joining the vane and bracket.

Fig. 9 is a detailed sectional view of another of the elements of the attaching means.

In the drawings and in the specification, in which like reference numbers designate similar parts, a window air vane device In shown in Figs. 1 to 5 inclusive, is comprised of a bracket II, a vane I2, attaching means l3 joining the vane rotatably to the bracket, and control means l4 resiliently holding the vane in functioning position and limiting its angle of rotation about the bracket.

The bracket I l consists of a tubular arm 15 and a rod [6. The tubular arm 15 has a flange I! at one end and is secured to the window frame by screws l8 extending through the flange and into the frame. The other end of the tubular arm is bent to form an elbow l9 having internal threads 20. The rod I6 has a positioning stop or transverse flange 2| intermediate its ends and external threads 22 on its lower end engaging the internal threads 20 of the elbow [9 to form an L shaped bracket. A hexagonal nut 23 threaded on the rod threads 22 locks'the tubular arm 15 and rod l6 firmly in position.

The vane l2 consists of a rectangular plate made of a transparent and light material such as Lucite, and is provided with two holes 24 aligned parallel to the shorter sides of the vane and positioned nearer to a shorter side 25.

The attaching means [3 rotatably joining the vane to the bracket consists of two bearings 26 (see Fig. 5) and two nuts 21.

Each bearing 26 has a circular head 28 with a hole 29 extending therethrough at right angles to its threaded shank 30 which extends through the hole 24 of the vane, and is clamped by one of the nuts 21. A portion 3| of the head where the shank joins it, is fiat and normal to the shank axis. The holes 29 of the bearing 26 can admit the bracket rod IS in a sliding fit that permits bracket.

3 the bolt to turn freely on the rod but cannot pass the positioning stop or flange 2| on the rod.

The circular head 28 engages a spherical member 28, snugly fitted on the vertical bracket rod 7 l l, and provides a self centering bearing therefor;

In assembling the vane and bracket, the bearings 26 are first extended through the holes 24 in the vane until the flat portion 3| of the bearing headis flush with the face-of the vane and the holes 29 are aligned one above the otherl The unthreaded end of the rod I6 is then inserted in the holes of the bearing until the lower bearing rests against the stop or flange 2!. The nuts 21 can be threaded on the bearing shanks 30 to lock the vane in position on the bolts, the vane and bolts being capable of turning freely on the rod 16.

The control means [4- resiliently holding the vane in functioning position comprises a pair of end aligned chains 32 and 33 having their adjacent inner ends connected to opposite 'ends of an interposed coil spring 33'. end 34 of the chain 32 is secured to the bottom of the vane 12 near its other shorter side 35, and the free end 36 of the chain 33 is secured to the tubular bracketarm l5 near its flange H. The spring 3| enables the control to be resilient thus reducing the risk of damage in highwinds or gales. The length of the control means I-4-can be varied and depends on the size of. the vane, the size of the window, and the positioning of the window air vane device within the window frame. r 1

By means of this device, abreeze'wh'ich is moving outside a window but does not enter it, can turn the vane I 2 until it is held by the control means l4 when the vane will deflect themoving airthrough the open window. Since the vane can rotate freely on the rod I6, changes in direction of the breeze will turn the vane automatically to permitmaximum deflection of the air currents into a. room;

In the variation of the invention shown in Figs. 6 to 9 inclusive a window air vane device 3'! has a. bracket 38 similar to the bracket I 1 except that its bracket rod 39 does not have the flange 2| that is on the bracket rod H5. The device has a vane 40, similar to the vane l2 except that holes '4! in the vane 40 are not threaded, and attach-' ing means 42 joining the vane rotatably to the The attaching means 42 consists of two eyebolt shaped elements 43, two supporting collars 44, ball bearings 45, and two nuts 45. Each eyebolt element 43 has an opening 41 therethrough capable of admitting the rod 39 in a loose fit, a

fiangei48 about the opening, and a threaded shank or pin 49 extending at right angles to the opening 41. The threaded pins 49 fit snugly in'the holes 4! of the vane '40 and are adapted to mate with the nuts 46 to'lock the vane to the eyebolts.

, A circular raceway 50 concentric with the openways 50 and 54 are formed and positioned to receive ball bearings 45 to permit free rotational The outer free movements of the eyebolt elements 43 relative to the collar 44. V A The device '31 is assembled by fitting the 601- 4 lars 44 and the eyebolt elements 43 on the rod 39, the collars being stationary and fixed, and the eyebolts rotating freely thereon and being spaced so that their pins 49 can be inserted in the vane holes 4!. The nuts 46 are then threaded on the ins 49 looking them together so that the vane 40 can rotate freely about the bracket rod.

As before, a resilient control means 56 limits the angle of rotation of the vane and holds it in functioning position resiliently, 1
