To all wlwmfit may concern:

`Be it known that I, Joii'N VAN Velisti?,- a citizen of the, United States, residing at Scotia, in the vcounty of Schenectady and .State (if 4New York, hav-e invented certain new and useful .Improvements in Motorists Eye-b`liieldsg and ll doderlare the following to be a full, clear, and exact description of| the invention, such as will. enable others skilledv in theart to which it appertains to` make and use the saine.

My. invention is an improved eye shield for use on automobiles to prevent the glare from the headlights of approaching vehicles from momentarily blinding the operator of' scribed and claimed, the descriptive"matter being supplemented by the accompanying di'aiijing which constitutes a part ofthis a'p plie-ation and in' which:

Figui-e 1 is a side elevation of a portion" of' an automobile showing the application of the `invention thereto;

device with the Fig. 2 .is an enlarged side elevation of the attaching vclamp partly .in a l v i l 1 'l A i l Fig. 3 is an edge View o't itlidnppe'r portion thereof;

Fig. ,4l is an enlarged verticalfsection taken ""Fig. :'i is a plan'i'iewA of the lpartially coin- "lnspecilirally destfribing the eoiistiuetioii shown iii` the drawing above Vbriefly described, similar characters will beplarml on corresponding parts throughout the 'several views, and'referenee Will be herein made to the, numeroi`is elements b their respective indices. To this end, the nuiueral'i represents a pliable tube carrying at one end a ing adapted to be swan into the operators line of "vision to shieh his eyes from the glare. of the headlights of approaching machines.

The tube l formed of asingle strip ofi metal 5, this strip being Ssliaped in cross section and vbe iig 'coiled as shown, with the curls at the ed ges of the numerous convolutions interengigirig suoli curls on the adjacent eoni'olutiuns. Certain of these curls constitute an internal shoulder (5 which. serves as a seien' thread in a manner to be hereinafter set forth.

A clamp 7 is provided for securing the plate 2 to tle tubey l, this clamp being formed of a single. strip of appropriate metal 8 having; on its ends fiat jaw plates A9 (see more pari icularly Fig. 5). The central portion of th( strip 8 is preferably in the form of a disl: l() as shown, ythis formation being attaineiliby suitably notching the edges of said strip. lYitii the exception of4 the disk 10, th i strip 8 is stamped into semiltubiilar. shape, the inner portions ofV the plates 9 being`- also shaped in' this manner to reinforce sind plates. Screw threads 1l are stamped oli the strip 8 between the disk- 10 and the j ai'i plates 9 as shown. .The general outline shawn in l4`ig. 5, and the stamping operations described may all be attained at a single operation by appropriate dies, thus rendering the clamp extremely easy to manufacture. After completing the' forma'L tion deseribei the strip 8 is folded substanliall y iipo i itself to bring the jaw plates 9 iiito parallel relation and at vthesan'ie time to `forni aspl t attaching plug or shanlgl), for rand-dans the inner end of this` shank being- Jroi-ined by the disk-likeforinationlO, said end beii g of less diameter than` the outeij end of he shank.v

The'shank 12 is threaded into the upi'ier e'nd of the pliable tube 1 with its screw tlireads ll 4frictionally engaging the thread or slu'iulder't \\'i.thin 'said tube; and the eye shielding plate 2 is clamped..between4 the jaw plated), these plates being forced into binding .zouta'et with said plate-2 by "the tapered fm'n'iatioii' ,of the shank 12.

The fricliona contact' existing between the shoulder (3 anl the threads 1l is such aste tend to contra it the eoiivolutions of the strip vcoiivoli'itions i fill-contract around said shank and Iwill thus positively hold it against removal by turning in the direction mentioned. Inorder to remove the clamp should it y be desirable for an reason, it is first neces- -sary tov expand the convolutions at the upv per end of the tube 1,v and for'this purpose one edge of the 'plates 9 at the juncture of this. edge with ,the shank is so shaped las to-cause it vto 'serve 'as al tubel expanding cam 13. This is accomplished bydlsposing said edge at a very obtuse angle to the shank, whereby if the clamp be turned further in the direction .in which. it must be moved to apply it to the tube 1, thefeam 13 15 will be drawn intoI the upper end of said tube. The result of thisisthat the convoluvtions .at this `end of .the tube will be expandedf-and will thus disengage the shoulder 6 from the, screw threads 11. {Simultagomeously' with" this releasing, the shank 12 will move''outwardly a distance approximately equalito the width of one ofthe threads 11. When the plug is in this position, due toits tapered formation,l there will be no noticeable amount of friction existing between it argd the tube, and consequently it may be rotated in :the reverse direction and removed. The upperend of; the tubel is.. ,preferably disposed obliquely as shown at 1* in order that the cam-13 may operate more quicklyv thanjwould otherwise be possible.

" The clamp. 3 above referred, to is prefer'd ably Vin lthel form of a split collar having overlapped. ends, the innermost of these endshaving a' threaded. opening 'p14 w-hile the outer end is tformed with a circumferentially spaced 1 series ofl vunthreaded openings-15..`

, In applying the devic, the `collar is ex- -panded and passed-around the steering. post 4, after which a screw 16 is passed through the appropriateopening 15 and threaded through the opening '14?A into' Contact with said post. This type of clamp will be very K eliicient regardless of its extreme sim- -plicity.

.By constructing the entire device` in the manner above fidescribed it may be easily and inexpensily manufactured and marketed and vwhen appliedto use:l will be .'a

very easily `lipcratedgand effective article.

'.D'e tothe structure .of the Atube 1, it is plif able in' all directions and 'may thus be .quickly andeasily moved. to position the f plate2 in the drivers line of vision. This 5 5v may be accomplished without moving either l hand-'to a olnt remote from the steering wheel as be 'obvious from aninspection 'ofjFig. 1. y I'claimrff 1.
