LEIGH G. GARNSEY, OF REDLANDS, CALIFORNIA.
RADIATOR SHUTTER.
Application area April a1, 192e.
Anobject of this invention is to provide cheap, simple and effective means tor regulating the temperature of internal combustion motors having radiators.
In the invention I provide at one end ot the radiator a spring take-up curtain roller with curtain wound thereon, in which the spring brackets orn the roller are mounted at one margin ot one end of the radiator in such position that when the curtain is drawn out or extended, it will close the ends ot cellular openings and obstruct the flow of air through those of the radiator tubes thus covered; and I connect with the bar ot the curtain, flexible means leading to position for control by the driver ot the engine, so that by drawing the connection the curtain may be adjusted across the open ends of some or all of the radiator cellular' openings, and by releasing the connection, the curtain will be rewound on the roller, thus allowing air to flow freely through to cool the radiator more or less, depending on the number of cellular openings left Jfree.
The curtain may be applied at either end of the radiator and the connection which is adjusted may be held in adjusted position by securing it to the dash board or other convenient part of the vehicle within convenient reach of the driver.
In carrying out the invention I have mounted the spring take-up' roller at the lower margin of the iront end ot the radiator and have run the flexible connection from the curtain bar up in front of the radiator and through the upper part of tubes on opposite sides of the top of the radiator, but it is understood that the curtain roller may be journalled at front or back ot the radiator and at top, bottom or sides of the radiator as preferred by the constructor.
Further objects of the invention are cheapness, compactness and simplicity ot construction, ease of application, and convenience of operation.
Other objects, advantages and features ot invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.
The accompanying drawing illustrates the invention.
Figure 1 is a perspective view of a device embodying my invention applied to the front end of the radiator of an automobile, a traction of which is shown.
Serial No. 103,421.
Fig. 2 is an enlarged fragmental detail partly in section.
Fig. 3 is a fragmental detail on a yet larger scale of the parts shown at the lower lettcorner of Fig. 2. The radiator cellular openings are omitted.
The radiator 1 of an automobile a is shown provided on the front end with a curtain 2 mounted on a spring operated take-up roller 3 the ends of which are mounted in brackets 4, 5, which are attached at the side edges of the radiator in such manner that the roller extends across the lower end thereof so that when the curtain 2 is drawn up a greater o-r less extent it will cover the outer ends of the radiator cellular openings to a greater or less degree as may be desired to restrict the flow of air through the radiator cellu la'r opennigs.
Guide wires 6 are attached at one end to the base of the brackets 4, 5, and the other ends are attached to the upper end of the radiator, preferably being stretched taut and wound about the outer end ot tubes 7 as indicated in Fig. 3.
The curtain is raised or lowered by means of wires, cords or other suitable flexible connection 8 attached at either end oi the cur tain bar 9, carried through the tubes 7, and the hood 10, and through the dash board 11 to a drum 12 which is in easy reach ot and operable by the driver` (not shown).
The tubes 7 are held in place by means of nuts 13 screwed onto the threaded ends of the tubes 7 and the journal brackets 4, 5 are attached by means of bolts 14 inserted through tube 7 and held by nuts 15, and felt and metal washers'lG, 17 to protect the surface of the radiator from being marred by the bolts and nuts 14, 15 and brackets 4 and 5.
A housing 18 protects the roller 3 and the curtain rolled thereon and is held in place by the bolts 14 which also attach the brackets 4 and 5 to the radiator.
The outer surface of the curtain is preferably marked as at 19 to simulate the front of the radiator and thereby render it less conspicuous.
I claim 1. In combination with an automobile radiator; of tubes disposed in the upper and lower ends of said radiator; bolts extending through the lower of said tubes; brackets secured to the base of said radiator by said bolts; revvinding roller journalled in said brackets; a curtain sheet arranged to Wind nected to the radiator by said bolts; a re- Winding roller journalled in said brackets; a curtain arranged to Wind upon said roller and adapted for movement vertically along t-he front of the radiator; cables connected to the free end ofsaid curtain and adapted for passage through the uppermost tubes and Wires connected to said brackets and upper tubes for guiding said curtain.
In testimony whereof, I havehereunto set my hand at Los Angeles, California, this 24th day of March, 1926.
