Patented July 29 1930 SAMUEL E. HOLT, or mim-EBEoK, NEWiYORK '5 LOUVER sii r'rER a Application filed December 27, 1927. serial m5, 242,691Q' V This inventionrelates to a louver. shutter, primarily for use with the hoods or engine coverings of automobiles, aeroplanes or other vehicles in which is employed a gas or other motor which to operate most efliciently should be kept at a certain temperature, especially in cold weather, and having a covering so ranged asto provide for circulation of air during hot weather, but providing means for 19 retaining the hot air during cold weather.
Thus in the operation of automobiles in winter, it is essential that the louver openings in thehood be partly or fully closed to prevent the escape of the hot air from the motor,
in a similar manner to that now in use for regulating the amount of cold airwhich passes through the radiator.
The object of the present invention is to provide means either to be incorporated into 2c the manufacture of the hood, or to be in the form of an attachmentwhichmay be attached to any hood now in use, and which may beoperated to partly or fully close the louver open- Another object is to provide a louver shutter or closing device that is so arranged as to partly or fully close the louver openings, and provided with means for locking the device in any desired position.
Still another object is to provide a louver shutter that shall be easily operated and free from noise and rattle; and in which each shutter can be operated in an independent manner from the other, so that the louver shutter on one side of the hood may if desired be partly closed and the other fully closed, this condition being desirable when a cold wind strikes one side of the automobile dur-' art hereof jandfin whi'eh 1ike figures of at the views, but it is understood that'sli'gh t the spirit of theinvention. 1 In the drawings erence refer to corresponding parts in all of Figure 1 shows the inside of an automobile hood,[formed with the usual louvers and hav ingthelouver shutter attached or incorpo rated into themanufacture thereof. Figure 2 shows a similar view of the inside of one side of an automobile hood, with the louver shutter mounted as anattachment.
'Figure-3 shows ayertical section of" the hood, shutter and attaching meansas used in the construction shown in Figure'2. A
V Figure 4: is an enlarged fragmentary sectional, view of a modified form of clamping means for the shutter. i i 1 i Figure 5 is a similar viewshowing 'stillanother form of guiding and clamping meansz Figure 6 is a partial sectional view to illustov trate how the material shearedfr'or'nthe open= ings in theshutteris folded backupon itself to stiffen the-bar between said openings; H
Referring to the-drawings, the usual automobile hood side '10, is showhwhi'chis formed with the'usual series of louvers 11 and louver openings 12. i
. In the construction shown inFigures 1 and 8, which is intendedto be a part of the hood when the same is made,-there aretwo gui'de strips-13, being formed with ano'fiset 14 and the body portionbeing'secured to the side of the hood 10 by thebolts 15 passed therethrough and secured by the lock washers 16 Y and the nuts 17.
Within these guides is slidably mounted a louver shutter,comprising a sheet of suitable material such as a light metal, which is formed with a series of openings 19 adapted to register with the openings 12 in the hood when the shutter 18 is in the proper position, and a tongue 20 formed on one end thereof and 'providedwith a slot 21, within which is mounted a bolt extending through the hood 10, and provided with a lock washer 22 and V a wing nut 23, for locking the shutter 18 in any desired position, the lock washer providing a tension to prevent rattle or noise.
In the construction shown in the remaining figures and which is intended as an at tachnient for hoods now in use, the uiding and mounting means is shownin the Iorm of a series of clamps 24.
These clamps 24 as shown in Figure 4, being formed with a curved end adapted to en gage .the rolled or turned edge 25 of the shutter 18, and'held in place by a bolt 26 passed through the side of the hood 10, andprovided with a coil spring 27 or look washer 28, retained by the wing nut 23 or the usual nut 17; the idea of the spring 27 or lock washer 28 being to prevent rattle by providing a tension on the shutter 18 I In the construction shown in Figure 5, the clamp 29 besides having the curved end 30, is undercut as at 31,,so that it stands away from the hoodlO and the action of the wing nut will produce a clamping elfect on the shutter 18, in such a maner that to move the shutter these nuts'23 Inust'first be loosened,
and then after the shutter is placedin proper position for partly or-fully closing the louver I openings, by the tightening of the wing nuts 23the shutter will be secured in place.
As shown in Figures 4, 5 and 6, the shutter 18 maybe reinforced by rolling theedge 32 over a wire 83, and by folding back the metal sheared from the openings 19 to stiffen the 'bars as at84,
Having thus described my invention, what I claim: as new and desire to secure by Letters Patent, is i p -A louver shutter, comprisingin coinbination with a-hood formed-with a seriesof louver openings in the sides'thereof, of a shutter comprising a single piece formed with a series a of openings adapted to register with said louver openings when ,in an-,op.en position, a beading. formed on the upperand lower edges of said shutter, guide strips formed with a grooved portion adapted to engage said beading and means for attaching said guide strips to said hood toexert pressure upon said beading to retain said shutter in an adjusted position with respect tosaid hood In testimony whereof I aflix my signature.
