2 Claims.

This invention relates to improvements inv safety goggles, and more particularly to safety goggles adapted foruse under conditions of high temperature and the hazards, of iiying spark particles, etc.

For example, men Working around melting furnaces and the like are subjected to dangerous heat and to ashes from. the furnaces, necessitating a high degree of protection for the eyes. The heat is frequently so intense as to excessively heat workers and cause burning of the face thereby. Also, unprotected goggles are ineffective to prevent the entranceof sparks or flying particles around and behind the goggles, thereby endangering the eyes. Further, such goggles are ineffective to properly shield the eyes of the wearer from perspiration caused by the excessive heat to which the worker is subjected.

Among the objects of my invention are:

To provide safety goggles completely heat insulated against. contact of the metal parts thereof with the face of the wearer; to provide such insulation of a form and characterso as to readily conform the same to the face contours of the wearer and to adequately absorb perspiration; and to render such a construction completely hash-proof and entirely safe against sparks, ying particles, and the like.

Additional objects and advantages will become taken glass mounted in lens frames 3 having'bows or earpieces 4, said lens frames 3 being connected by a central nosepiece `or bridge 5 between the lenses. The goggles also have ventilated rearwardly extending side guards 6 hinged at 1 to the outer portion of each frame 3 to rearwardly extending metal anges 8 thereof, said -iiangespreferably extending substantially around each of the said frames.

For the purpose of protecting the face of the wearer against contact with the metal frame of l0 the metal parts of the goggles worn by the Y secured to the inner portions of the lens frames 3 adjacent the nose, said pads being fastened as by riveting to the anges 8 of the frames. The pads are secured to and extend substantially around the adjacent inner one-half portions of the lens frames and have free terminal vportions or flaps I0 overlying the hinges 1 of the side guards 6, said flaps being of sufiicient length to substantially overlie the upper and lower contours of the said side guards 6, as particularly shown in Figs. 2 and 3.

The insulating pads 3 have their free longitudinal edges extending rearwardly a, suiiicient distance to provide flexibility and thereby enable o lthe same to readily engage and conform to the contours of the face of the wearer in the regions between the eyes and nose at the center portion of the goggles, the aps I0 of the pads increasing in dimension rearwardly and outwardly of the goggles for positive self-aligning conformity with the face portions above and below the eyes of the wearer. Similarly, those portions of the pads 9 at the top and bottom of the frames adjacent their terminal flaps I0l are tapered to merge with the said flaps in proper conformity with the face contours above and below the eyes.

The curved outer terminal edges of the side guards vIi are covered with a protective insulating pliant binding I I to engage and form a protective closure around the face portions outwardly beyond the eyes of the wearer; said bindings I I, the pads 3 and flaps I0 providing a completely encircling,

self-aligning closure between the goggles yproper v and the face of the wearer.

My invention also includes a nose shield I2 consisting of a nose pad I3 of leather extending from thenose piece or bridge v5 downwardly beof the wearer. The nose pad I3 is also made full or pouch-like so that the same will readily and comfortably conform tothe nose contour.

In addition, the nose shield I2 includes a reenforcing and stiffening band I 5' of ne wire mesh gauze or screen secured to the upper portion-of the shield and on the outer surface thereof between the lens frames, said band extending downwardly at least to the point of substantial the goggles, VI provide insulating pads 9 of leather 55 divergence of the lens frames away from the nose. In addition to its stiii'ening and reenforcing properties, the wire mesh of the band I5 functions to intercept and dissipate radiated heat, thereby protecting the leather nose shield as well as the nose.

The shield I2 is formed by stitching the wire gauze or screen I5 to the pad I3, and then stitching the latter to the inner adjacent portions of the insulating pads 9, thus forming a complete over-all insulating and protecting covering for H,

the metal portions of the goggles and for the nose to shield against burning the face of the wearer. i

I have found that excellent results are obtained from the use of Carpincho leather or tanned wild pigs hide for the pads 9, flaps I0, bindings II, and nose pad I3. This type of leather remains soft and pliant over long periods of time under extreme heat and will adequately absorb perspiration. Also, this leather will resist and deflect hot sparks or foreign particles encountered in the field of use for which the present goggles are intended.

frames, heat insulating pads of pliant material disposed about and secured to the frames, and a nose shield of heat insulating pliant material disposed between said frames, said nose shield including a .band of finewire gauze disposed thereover on the outer surface of the shield between the frames, and extending downwardly at least to the point of substantial divergence of the lens frames from the nose of the wearer.
