Specification of Letters Patent.

Application filed March 18, 1916. Serial .Nc. 85,097.

To all it may concern: 1 Be itknown that I, VVAL'I'ER E. STEPHEN- soN, a citizen of the UnitedStates, and a residentof Roosevelt, in the county of Nas sea and State of New York, have invented a new and Improved Motor-Radiator Air- Draft Control, of which the following is a full, clear, and exact description.

My invention relates to means for re ulat- 1 ing the air circulationlhrough the ra iator provide a simple and inexpensive .device' whereby air 'may be caiised to circulate through some part of the radiator while itv object of the invention is'to provide a device of the class described whereby air may .be' caused to circulate through the entire radiator or prevented entirelyfrom circulating through. the radiator.

.W1th the above and other objects in view; the nature of which will more fully appear as the description proceeds, the invention consists in the novel constructiom combination and arrangement. of parts as herein fully described, illustrated and claimed. In theaccom'anying drawings, forming part of the app ication, similar characters of reference indicate corresponding parts in all .the views.'

lligure 1 is a side elevation. of a motor vehicle radiator provided with anembodiment of my invention, certain parts of which invention are brokenaway to show the details of construction, the airalraft control in this figure being shown obstructing the air circulation through the radiator Fig. 2 is a similar-view showing the airdraft control of the radiato1j=permitting cir' culation through the upper=partof the radiator while-preventilig ail ?circulation ina the lowerpart thereof; V F ig. 3? is a view similar tmFig. 1, showing the "air-draft control in the. position per-- 45m itting partial obstruction of the circular tion iiiboth" the upper and the Lower parts; 4 is a frontelevation of the device showmin Fi shown in section aboutthe deriee; and 60 Fig.i 5; isa, fragmentary enlarged section throu'h the radiatorand device. 1

It will be seen from Figs. 1. 2, and 3 that all the slots are open into the edge 'ofjthe slide' restin g against the radiator so that the extensions 12 of the shlltl ers may come inoontact with the surface of the radiator, thereby allowing 'se the shutte'rto' come in contact with the sur k face of the ra liat'or, thus perfectly' closin g the cells and obstructing flow of air threthrough- A lumber; of the upper slots marked 15 are arcuate and are atagreater slides 13 have an 'initial displacement rela 'tivmr to the exivensions or shutters engaged by said s1ot'13 before said extensions are angle to the :dge of the slide than the i engaged hy the straight sides 18 of the-" slots.
