Abstract
Abstract Eyeglasses which have temples made of a material which is substantially rigid at atmospheric temperatures but ductile at a temperature above atmospheric temperature, and a weighting material encapsulated in the material of which the temples are made which is substantially rigid at atmospheric temperatures but liquid at the temperature at which the temples are ductile and the method of fitting said eyeglasses including the steps of heating the temples until they are ductile and the weighting material is liquid, shaping the temples while they are ductile and the weighting material is liquid, and cooling the temples to solidify the weighting material and to make the material of the temples substantially rigid.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
74 words
In eyeglasses having a pair of ocular pieces; a bridge interconnecting the pieces; and temples rearwardly extended from the ocular pieces, said temples comprising a weighting material, and a relatively lighter material encapsulating the weighting material, the weighting material having a substantially higher specific gravity than the encapsulating material and a melting point above normal atmospheric temperatures and the encapsulating material being ductile at said melting point but substantially rigid at normal atmospheric temperatures.
Claim 2
Dependent Claim
74 words
In eyeglasses having a pair of ocular pieces; a bridge interconnecting the pieces; and temples rearwardly extended from the ocular pieces, said temples comprising a weighting material, and a relatively lighter material encapsulating the weighting material, the weighting material having a substantially higher specific gravity than the encapsulating material and a melting point above normal atmospheric temperatures and the encapsulating material being ductile at said melting point but substantially rigid at normal atmospheric temperatures.
Claim 3
Dependent Claim
17 words
The eyeglasses of claim 1 in which said melting point is from approximately 47° to 70° C.
Claim 4
Dependent Claim
18 words
The eyeglasses of claim 1 in which said encapsulating material is ductile from approximately 60° to 94° C.
Claim 5
Dependent Claim
90 words
Eyeglasses comprising a pair of ocular pieces, a nose bridge interconnecting the pieces, and temples individually extended from the pieces adapted to rest on the ears of a wearer and to provide ends extended rearwardly of the wearer's ears, the ends being of a material which is substantially rigid at normal environmental temperatures and ductile at a temperature above said normal environmental temperatures and having cavities therein, and weighting material substantially filling the cavities having a melting temperature above normal environmental temperature but below the ductile temperatures of said material.
Claim 6
Dependent Claim
90 words
Eyeglasses comprising a pair of ocular pieces, a nose bridge interconnecting the pieces, and temples individually extended from the pieces adapted to rest on the ears of a wearer and to provide ends extended rearwardly of the wearer's ears, the ends being of a material which is substantially rigid at normal environmental temperatures and ductile at a temperature above said normal environmental temperatures and having cavities therein, and weighting material substantially filling the cavities having a melting temperature above normal environmental temperature but below the ductile temperatures of said material.
Claim 7
Dependent Claim
19 words
The eyeglasses of claim 4 in which said material is cellulose acetate and the weighting material is Wood's Metal.
Claim 8
Dependent Claim
48 words
In eyeglasses having temples of a material substantially rigid at normal environmental temperatures and ductile at a temperature above normal environmental temperatures, a weighting material encapsulated in said temples which is substantially rigid at normal environmental temperatures and fluid at the temperature at which the temples are ductile.
Claim 9
Dependent Claim
48 words
In eyeglasses having temples of a material substantially rigid at normal environmental temperatures and ductile at a temperature above normal environmental temperatures, a weighting material encapsulated in said temples which is substantially rigid at normal environmental temperatures and fluid at the temperature at which the temples are ductile.
Claim 10
Dependent Claim
32 words
The eyeglasses of claim 6 in which the temples have rearwardly extended ends adapted to extend rearwardly from a wearers ears and the weighting material is encapsulated in said rearwardly extended ends.
Claim 11
Dependent Claim
117 words
In a pair of eyeglasses having a pair of lenses, a nosepiece disposed between the lenses adapted to rest on the nose of a wearer, and a pair of temples individually extended from the lenses rearwardly over the ears of the wearer and terminating in rearwardly extended ends, said temples being substantially rigid at normal environmental temperatures and ductile at a temperature above normal environmental temperature, the rearwardly extended ends of the temples each having a cavity therein, and a weighting material having a specific gravity greater than that of the temples substantially filling said cavities, the weighting material being substantially rigid at normal environmental temperatures and liquid at the temperature at which the temples are ductile.
Claim 12
Dependent Claim
117 words
In a pair of eyeglasses having a pair of lenses, a nosepiece disposed between the lenses adapted to rest on the nose of a wearer, and a pair of temples individually extended from the lenses rearwardly over the ears of the wearer and terminating in rearwardly extended ends, said temples being substantially rigid at normal environmental temperatures and ductile at a temperature above normal environmental temperature, the rearwardly extended ends of the temples each having a cavity therein, and a weighting material having a specific gravity greater than that of the temples substantially filling said cavities, the weighting material being substantially rigid at normal environmental temperatures and liquid at the temperature at which the temples are ductile.
