GOGGLES Filed Sept. 20, 1956 INVENTOR. JOSEPH H. UPHOFF ATTO R N EYS United t e, Paten 2,886,819 GOGGLES Joseph H. Uphotf, wooubuni, Oreg. Application September 20, 1956, Serial No. 1 Claim. or. 2:14

The present invention relates to improvements in goggles, and more particularly to goggles which are specially adapted to be used in connection with painting, spraying, dusting, grinding and the like.

The primary object of the invention is to provide goggles with transparent lenses that are renewable while wearing the goggles, so that when the lenses become dirty or marred new transparent lenses can be brought into place by the wearer of the goggles. In order to carry out this object, it has been found that a transparent window in the form of a sheet rolled on reels is best adapted to accomplish the object. In replacing the soiled or damaged sheet, the same is rolled onto a reel, the fresh material being unrolled from a reel by the operator.

A further object of this invention is to construct a goggle that will completely resist the entrance of dust or dirt, but at the same time will permit ventilation through the goggles.

Other objects and advantages will become apparent in the following specification when considered in the light of the attached drawings, in which:

Figure 1 is a perspective view of the invention, partially broken away for convenience of illustration.

Figure 2 is a front elevation of the assembled goggles.

Figure 3 is a plan view of the invention, partially broken away for convenience of illustration.

Figure 4 is a transverse sectional view taken on the line 44 of Figure 1, looking in the direction indicated.

Figure 5 is a fragmentary front elevation of the goggles with the transparent lens removed therefrom.

Figure 6 is a front elevation of the transparent lens material shown associated with reels for reeling and unreeling the material from one reel to another.

Figure 7 is a fragmentary plan view, partially in section, illustrating a shield for covering the roll of fresh transparent window material.

Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures, the reference character F indicates generally a framework for the goggles comprising a pair of rectangular frames 10 and 11 secured together by the nose bridge 12 and the central portion 13 of a dust shield S.

The rectangular frames 10 and 11 consists of vertical frame members 14 and 15, connected together by horizontal frame members 16 and 17. The horizontal frame members 16 and 17 have guideways 18 for guiding transparent lens material 19 throughout the width of the rectangular frames 10 and 11.

The dust shield S consists of sheet material 20, extending rearwardly from the frame F and may form an integral part of the frame F, as best illustrated in Figure 4. The shield S extends rearwardly of the goggles to conform to the shape of the forehead and checks of the wearer on both sides of the nose.

The dust shield S is provided with a peripheral head 21 along its rear edge and has engaged thereover a re- 2 silient' pad 22 engaging the forehead of the wearer and lower extensions 23 for contacting the upper portion ofthe" cheeks of the wearer.

Ventilating openings 24 may be provided, preferably made of screen or other material that will allow air to pass through, but resisting the passing of dust therethrough. The portion 20 of the shield could be of a very fine screen, but I would not wish to be limited to this particular kind of material other than it should be dustproof and have the ability to hold the frames F of the goggles at the proper position in regards to the" nose and eyes of the wearer.

The usual head band 25 may be connected to the shield S, or ear bows (not shown) as used in regular glasses could be extended from the frame F if desired. Goggles usually have an adjustable head band so they can be readily adapted to all sizes of heads.

The transparent lens material 19, referring to Figure 6, is wound about a roller 26, similar to film on a film roll, and is transferred to an empty roller 27 while the goggles are being used. The roller 26 and the roller 27 each consist of the usual hub 28 and the end disks or flanges 29, having a spindle 30 associated therewith. Extending forwardly and outwardly from the frames 10 and 11 are spring clips 31. The clips 31 have bearings 32 fonned therein to receive the spindles 30* of the rollers 26 and 27. The peripheries 33 of the end flanges 29 are preferably corrugated or roughened at 34 so that they can be easily rotated by the fingers of the operator.

Referring to Figure 7, a shield 37 is shown hingedly connected to the frame F of the goggles at 38. The shield 37 is adapted to cover the unused roll 26 of transparent lens material 19, preventing damage to the material 19 on the roll 26 before being used. The shield 37 isadapted to be moved to the broken line position for installing or removing the roll 26 from the clips 31.

The operation of this new and improved goggles will now be described. The spindles 30 of the full roller 26 are entered between the spring clips 31 and forced towards the frame F of the goggles, registering the spindles 30 with the bearings 32 of the clips 31. The transparent lens material 19 is then threaded through the guideway 18 and the reduced end 35 of the material 19 is threaded into the slot 36 of the empty roller 27, after which the roller 27 is revolved, rolling the transparent material 19 thereon. The clips 31 tend to press against the ends 29 of the rollers 26 and 27, causing a friction to the rotation of the rollers 26 and 27 so that the material 19 will be stretched tightly between the rollers 26 and 27 at all times.

The guideway groove 18 is of a width to prevent dust and material from passing between the transparent material 19 and the groove 18, but providing free movement of the lens 19 therethrough.

In the use of the goggles, as the transparent sheet material 19 becomes dirty with paint or chipped with grinding material or the like, the operator simply rotates the rollers 27 so as to wind the marred material 19 onto the rollers 27, bringing in a fresh section of material against the front of the frames 10 and 11, ready for further use. a}

The lens material 19 comes on fresh reels 26 from the source of supply and is readily transferred to the goggles at the point of use.

Having thus described the preferred embodiment of the invention, it should be understood that numerous structural modifications and adaptations may he resorted to without departing from the scope of the appended claim.

What is claimed is:

A pair of goggles comprising a pair of frames arranged in laterally spaced relation, means securing said frames together, means on said frames for supporting and detachably securing said frames in dust-tight relation to the head of a wearer, a pair of spaced parallel horizontal channel guides formed on each of said frames with the guides of each pair having the channels thereof arranged in facing relation, a flexible transparent lens supported on each of said frames with each of said lenses having spaced parallel edges engaged in said channels of a pair of said guides for longitudinal movement therein, a pair of rollers associated with each of said frames with said rollers having their axes vertically disposed, each pair of said rollers having the respective opposite end portions of one of said lenses wound there- .4 spective upper and lower ends of said rollers iournalliug said rollers for rotation about their vertical axes whereby on rotation of one of said-rollers an associated lens is wound thereon while simultaneously unwound from the roller on which the opposite end of said lens is wound.
