complish all of the Patented Nov. 4, 1930 PATENT OFFICE CLIFF R. OTTO, OF EDMOND, OKLAHOMA mm'rus noa-nnnamarms ICE rnom wmnsnmnns Application filed February 4, 1929. Serial No. 337,512.

My invention relates to apparatus for and method of eliminating ice from the windshield ofautomobiles. I

The objects of my invention are to produce a' device of the-class described which will be new, novel, practical, useful and of utility; which will be economical in construction, installation and operation; which will be removable; which will beeasily installed upon any automobile; which will be compact. and easily carried; which will acpurposes for which it is intended.

There has previously been some attempts made-to eliminate the freezing of moisture upon the automobile wind-shield, such as: placing a lighted candle upon the inside of the car and near the wind-shield thereof;

and the installation of electrically heated coils and wires adjacent the wind-shield, operating by electricity from the "bottom of theqcar. Theluse of a burning. candle is not a success for night driving, because the light of the candle must necessarily be direc'tly between the driver and the wind,

shield. This is dangerous because it ob'-' structs the drivers vision and also because the candle is-liable to fall from its position and ignite the clothing of the occupants, or somepart of the automobile. It is impractical also because'it will burn only in a closed car. The use of heated coils and wires have proven impractical owing to the fact that they use an excessive amount of electrical current, and thus, run 'down or discharge the battery very quickl The installation and use of .a 'deviceof this nature is usually vervexpe'nsive. v a 1 y invention is not operated by electricity and therefore'does away with expense of operation which is encountered in electrically heated coils, and the like, and it is not required to be heated. Theconstruction of my-device is much chea r than most methods, and eliminates all anger from fire. It may be removed and .carried inside the car when it is not in use. -It may be installed for use quickly. The'operation thereof is of very little expense.

With these and other objects in view as will more fully appear my invention consists in the construction, novel features, and combination of parts hereinafter more fully described, pointed out in the claims hereto appended, and illustrated inthe accompanyingTone-sheet drawing, of which,

f igure 1 is a fragmentary perspective View of the front of an automobile, showing myinve'ntiou' installed thereon; Fig. 2 is a perspective view of the device, showing its relation to wind-shield and wind-shield wiper; Fig. 3 is a sectional view through reservoir; Fig. 4 is an elevational View showing the end of delivery tube positioned against a fragment of wind-shield glass.

Like characters of reference designate like parts in all the figures.

It is understood. that various changes in the form, proportion,- size, shape, weight and other details of construction, within the 7 scope of my invention may be resorted to without departing from the spirit or broad principle of my invention and without sacrificing any of the advantages thereof; and it is also understood that the drawings are to 'be interpreted as being illustrative and not restrictive.

A practical embodiment of the invention as illustrated in the drawings includes: A quarter .round elongated tank or vessel 1, s0

-made ofv metal or other suitable material,

1 is felt strip 3, better seen in Fig.3.- Said strip 3 is to protect cross-frame 2 from scratching by tank 1,,and may be made of other suitable material-than felt, if desired. Tank 1 has bottom 4, vertical back 5, rounding top 6, and ends 7 and 8. Said top 6 has round, flanged opening 9 into which-is insert-' ed cork 10 with perforation 1 1 therethrough. Said 1 openi'ng'9 is for filling vessel 1 with liquid. Said perforation 11 insaid cork '10 is to allow the free passage of air into tank cross-frame 2.

the'other end of said nipple 16 being smooth and not threaded. Fitting over smooth end of said nipple 16 is one end of connecting hose 17. Said hose 17 is made of rubber or other suitable material and fits around said nipple 16 closely enough to allow no leakage of liquid between the two. The other end of said hose 17 fits over pipe 18 in the same manner as hose 17 fits over said nipple 16, allowing no leakage. Said pipe 18 is straight from its end at hose 17 to a point 19, adjacent its other end. At said oint 19 said pipe 18 is bent at an obtuse ang e as is shown in Figs. 1, 2, and 4. Upon the bent end of.

said pipe 18 and fitting snugly therearound is delivery hose 20. The loose end of said delivery hose 20 is cut off or terminated at an angle or bevel, better seen in Figs. 2 and ,4. The lip 21 of the beveled end of delivery powered or automatic. Adjacent the middle of said connecting hose 17 is provided screwclamp inch cock 25, of known make or'design. owever, it is preferred thatit be provided with an arm or plate for closing the usual 0 ening between the jaws, for better preventing the loss of same from the device. Said hose-clamp inch cock is for shutting off the gravitational flow of liquid from said tank 1 through said connecting hose 17 At the lower edge of said top crossframe2 and the pro er distance apart and both within the lengt of said pipe 18 is rovided screw-hooks 26' and 27, for hol ing said pipe 18 rigidly against said cross-frame 2. It will be seen that the curved top 6 of said tank 1 enables said tank 1 to be installed upon said automobile top cross-frame 2 without the removal of or interference withautomobile sun visor 28.

The installation of my invention, itwill be seen, merely consists of properly attaching said bolts or screws 14 and 15 and said supporting

hooks

26 and 27 to said automobile top cross-frame 2. Then the placing of tank .1 so that it and the entire feed-line thereto attached is supported upon said screws 14 and 15"andsaid hooks 26 and27. After tank 1 and the entire feedline thereto attached has been correctly positioned upon their respective supports, pipe 18 is turned in hose 17 so as to bring lip 21 of delivery hose 20 into touch with windshield 22. It will be seen in Fig. 4 that only the lip of'said hose 20 touches the wind-shield 22 and not the en tire beveled end thereof. This is to prevent the hermetical sealing of said hose 20 against the wind-shield 22. Said screw-clamp pinch cock 25 is kept closed at all times when device is not in operation.

In operation said tank 1 is filled with a saturate solution of sodium chloride, and said screwclamp pinch cock 25 is opened slightl to allow the passage of said solution through pipe 18 and delivery hose 20. Said lip 21 of vsaid delivery hose 20 conveys said solution to wind-shield. Said wind-shield Wiper 24 spreads said solution over the outside of wind-shield, and thus keeps a portion there of .clear of ice. The fiow of said solution to wind-shield may be governed by the-tightening or loosening of said screw clamp pinch cock 25; When the device is not in use it ma be lifted off said supports 14, 15, 26 and 2 and carried inside of the automobile, or tool chest. f

In using this device other liquids than sodium chloride may be used, such as: a

saturate solution of calcium chloride; a mixture of alcohol and glycerine; gasoline; or 'eitheralcohol or glycerine by themselves; or other suitable liquids, The useof sodium chloride is preferable, however, because salt may be obtained on the road at any store or almost any farmhouse or dwelling. It does not 'gum u the car as glycerine and the mixture of g ycerine and alcohol do. It does not ruin the paint or duco finish of the car a gasoline or alcohol does.

Obviously, the invention is susceptible of embodiment in forms other than that which is'illustrated in the accompanyin drawings and described herein, and applica le for the uses and purposes other than as detailed, and I therefore consider as my own all such modifications and adaptations and other uses of the form of the device herein described as fairly fall within the scope of my invention;
