provements in Radiator Shutters, of which.
the following is a specification.
This invention relates to air-deflecting shutters or vanes for regulating the cooling eifect of radiators especially for the circulating water or other liquid used in the water-jackets of motor-cars, tractors, airplanes or other apparatus employing internal combustion engines.
The principal object of the invention is to provide a novel means for regulating the flow of air'throu h the radiator.
Another object is to increase the cooling efi'ect of the radiator by the attachment to it of a metal structure having a great amount of radiating surface.
A further object is to deflect the course of the cooling air from a substantially horizontal plane (or a plane parallel to that in which the carer other vehicle is travelling) to a plane at a considerable angle thereto, in order to increase the radiating efiiciency of the structure.
Another object is to provide means for converting the usual form of radiator (without regulating device) into a more efiicient structure which may be controlled by theoperator to adapt it for varying weather conditions. The invention is not limited to an attachment for radiatorsas it may be incorporated in the radiator structure. 1
Other and ancillary objects will appea hereinafter.
In the accompany drawings which illustrate the invention,
Fig. 1 is a perspective view of the forward portion of a motor car showin the shutter-structure attached to the ra iator and the controlling device extending back to a point within reach of the driver.

away;
Fig. 3 is a similar view of the shutterstructure in its open position;
Fig. 4 is 'a perspective view of a fragment of one of the sheet-metal 'shutte'r-mem bers; and
Fig. 5 is a horizontal section taken on the line 5-5 of Fig. 3, partly broken away.
Referrlng to the drawings, the air defleeting and regulating means consists of two similar members 1 and 2, each consisting of a single piece of sheet metal. The
To the vertical strips 3 are attached by soldering or other means, vertical webs 5 for strengthening the structure. The ends of the vanes 4 are also soldered or otherwise attached to the sides of the webs 5, so that each vane is attached at one end to a vertical strip 3, at the other end to the vertical strip 3' and it is also attached to a vertical web 5. The member 2 is similarly formed of vertical strips 6 and 6', horizontal vanes 7 and webs 8. The vertical strips 3 and 6 are of a width approximately the same as the thickness of the webs 5 and 8 so that the ends of the vanes 4 and 7 which are attached to the strips 3' and 6' are in contact with the webs 5 and 8, and may be attached readily thereto by solder or other means. The vertical strips 3 and 6 and the spaces .between the unattached ends of the vanes 4 and 7 are slightly greater in width than the thickness of the webs 5 and 8 to provide clearance between the unattached ends of. the vanes 4 and 7 and the webs 5 and 8,
and permit the movement of member 1 in relation to member 2 without friction between the unattached ends of the vanes 4 and 7 and the adjacent sides of the ver- I tical webs 5 and 8, with which they are interlocked, but not in contact due to the clearances described.
Fig. 2 shows the member 1 in the position which entirely shuts ofi' the air from-the radiator 9, the member 1 being interlocked with the member 2' so that the rear edges sageof air between the several vanes 4 and the several vanes 7, which now register with them to form a series of angular passa es or ports, open at bothends.
e movement of member 1 is accom-.
plished by means of an arm 10, pivoted at 11 and actuated by a rod 12 which passes through the radiator and under the hood of the motor car to the control-board, where a handle 13 is provided, by means of which the rod 12 may be pushed forward to open the shutters or pulled back to close them. The flat bar 14' extends entirely across the top of the shutter structure and engages by means of the bars 19 and 20, which pass t r ough round holes 21 and 22 in the webs 8 and through slots 23 and 24 in the webs 5. The slots 23 and 24 are laced at the same angle as the vanes4, so t at movement of the member 1 is in a plane parallel to the plane in which the vanes 4 are set, and
transverse to the plane in which the vanes 7 are set. The front edges of the vanes 7 are always ad'acent to the rear surfaces of the vanes 4; t is relation of parts resulting in a series of angular air-passages or ports which may be adjusted to any size from zero to maximum by the movement of memher 1 in relation to member 2, as above described.
' .The member 2 is held in intimate contact'with the radiator 9, by means of bolts 25 which engage with the webs 8. Heat from the radiator is carried by conduction to the members 1 and 2, which present large radiating surfaces to the air which passes through them. The efiiciency of the radiator is therefore increased to a marked degree by the attachment of the shutter structure.
The angular relation of the vanes 4 and 7 causes the cooling air to change direction as it passes through the passages formed by the vanes and to impinge upon the radiating surfaces with a pressure which increases as the square of the speed. The radiating effect of the shutter-structure therefore increases in the same proportion as the load on the engine due to the resistance of the air. 'It is therefore unnecessary to shift the adjustment as frequently as would be desirable if the shutters were set in a plane parallel to the plane of' motion of the car, or were set at various angles to effect the adjustment.
