Description

Patented Apr. 7, 1931 UNITED STATES ROBERT MALCOM, F CHICAGO, ILLINOIS GOGGLES Application led October 5, 1928. Serial No. 310,505.

My invention relates to goggles used by workmen and the like wherein the two lens holding members or eye pieces are usually flexibly secured together to permit folding of the goggles into more or less compact form, with each lens holding member provided with suitable elastic straps adjustably secured together and adapted to fit about the head of the user.

My invent-ion has for its object the provision of a goggle wherein the body portions of the eye-pieces or members are composed of metal and a suitable composition or plastic material, such as bakelite, moulded into proper shape; the metal being immovably secured to the composition and constituting the glass or lens holding portion.

The invention also has for its object the provision of a Vgoggle provided with an air admitting screen which also constitutes the head-gear or elastic band holding element.

The objects and advantages of my invention will be readily comprehended from the detailed 'description of the accompanying ydrawing, wh-erein Figure 1 is a plan view of my improved goggle.

Figure 2 is a sectional plan view through one of the eye-pieces.

Figure 3 is a cross sectional view taken substantially on the line 3 8 of Figure 1.

My improved goggle as shown in the drawing comprises the usual eye-pieces or members 10, 10 which are of similar construction and configuration, so that a description of one eye-piece or member will suflice.

The body portion 11 of each eye-piece 10 consists of some suitable plastic composition which may be properly moulded into shape and then baked, as for example rubber or bakelite; the eye-piece being moulded to fit about the eye and somewhat conform to the contour of the head adjacent to the eye; with the outer side or wall made of greater width as sho-wn at 12. This is accomplished by gradually flaring or increasing the width of the walls from the inner side 13 toward the outer side 12, as more clearly shown in Figure 3.

Heretofore, goggles have been made by providing the moulded eye-piece with threads at the lens side of the eye-piece for the purpose of receiving a metal ring or band for holding the lens in place.

This method of properly threading the moulded or pressed composition to permit the metal ring to be screwed thereon involves a more complicated and expensive operation, while at the same time producing a goggle not adapted to withstand the wear resulting from` the screwing of the lens holding ring in place. Y

VMy invention is devised to overcome these serious objections and consists in providing the lens holding end of the eye-piece with a metallic band 14, which maybe secured to the body portion 11 in any suitable manner; as for example, by providing the band 14 on itsinner perimeter with an annular flange 15 embedded in the moulded body portion so as to have the intermediate portion 16 of the band provide a seat for the glass or lens 17. The outer perimeter of the band is provided with a forwardly presented flange 18 of width greater than the thickness of the 75 lens 17. This outer flange is threaded to receive a threaded ring 19; the ring being provided with an annular groove to receive the circumferential edge of flange 18 and at the same time permit the inner perimeter 2O of the ring to engage the lens and hold it snugly in place. l

The operation of forming and threading the band 14 is not only more easily accomplished than the operation of threading the moulded body portion, but the threads of the metal band and ring will withstand thewear incident to the screwing of the ring into place; removal of the ring and replacement of the lens being also more readily accomplished.-

Another features of my invention consists in providing the main body portion 11 with a screen or perforated metallic plate 21, to afford suitable ventilation. This screen or perforated plate 21 is preferably formed to t into a recess about an opening inthe outer side wall of the eye-piece 11. The outer side wall is provided with an elongated circumferentially disposed opening 22, preferably made of greater width intermediate of its ends; and the outer side of the eye-piece is preferably formed with a recess about this opening adapted to receive the screen 2l which may be suitably secured in place, as for example by the rivets 23, see Figure 2. In order to provide proper support for the screen 21 intermediate of its ends, I prefer to provide the lip 24 formed integral with the body of the eye-piece, see Figure 2, thus preventing an inward bending of the screen 21 through pressure that may be encountered by Contact of the lingers therewith.

This screen member 21 Which preferably consists of a perforated metallic plate, is provided with an integral lip or ear 25 eX- tending or bent outwardly at a proper angle as shown in Figure 3. These lips or ears 25 of both eye-pieces are each provided with an elongated opening or slot 26S-see Figure 1 to receive the ends of the headgear or elastic bands 27 (only one being shown in Figure l-the other being omitted to disclose construction). The ends of the bands are held in place in the slots in any suitable manner; and the two eye-pieces are in turn preferably flexibly connected by a small chain 28 encased in the rubber tube or covering 29 to prevent injury to the bridge of the nose.

The ieXible connection is suitably secured to the eyepieces, as for example by the fstaple member 30 which is secured to the body portion of the eye-pieces.

Generally stated, my invention involves a goggle, with the body portion of the eyepieces composed of suitable material of a plastic nature while in its raw state, as for example, rubber, bakelite, or other suitable composition, which may be readily compressed into the desired shape and baked; and with the lens holding means composed of metal; thereby producing a superior goggle and one adapted towithstand greater wear than is the case with goggle as heretofore constructed; the invention also involving the provision of vent means in the form of a screen which also constitutes means for attaching the headgear or straps to the goggle.

The. invention in what is believed to be its best embodiment has been described in terms employed merely as terms of description and not as terms of limitation, as structural modifications may be made without, however, departing from the spirit of my invention.

lllhat I claim is A goggle comprising a pair of eye-pieces composed of plastic material moulded and baked in shape, the outer side wall of each eye-piece being formed with an elongated opening disposed circumferentially, the outer face of the Wall about said opening being recessed, and a perforated metallic plate ROBERT MALCOM.
