A further improvement relates to the articulated bridge-piece which connects the two chambers B. 1
According to the present invention the ex tensibilit "of the bridge-piece is obtained by means o aconstruction differing from the tratedjin the previousfpa't'ent referred to" above. The metallic arch forming the bridgepiece is constituted by two bent stems D D', halved together, and each connected 6o at'oe end by a ball-andi-socketjoint d to the i spectacle-frame in orderfgto of the spectacles being folded up the' smallest possible'slaxce.

1 Zreasen thatthe driver of a motor-car must l necessarily -keep a constant lookout not-only .in-front of him but also at either side \as well f andho'th in his .immediate vicinity'and also 5` ata distance'in order to guard against accidents. The lenses now in use for such spectacles in' no way meet this requirement, as they are made With a view of obtaining a clear vision through their center alone, and
xo theyall give rise to phenomena (if deviation,
displacement, deformation, &e'., when the vision is directed toward their sides.
A person with normal vision capable, of
clearly ldistinguishing objects either close atr 5 hand or at a distance need only be protected' by neutral lenses,"and at present o nly two sorts of lenses are employed for use in suchcases'-viz., those which are flat on both faces and of uniform thickness, like windowzo glass, and those of curved glass,vpresenting two spherical concentric surfaces and also of uniform thickness; but these two kinds of neutral lenses do not give satisfactory results when employed as goggles. The necessity z5 which the`driver of a motor-car is under of very attentively guarding against accidents by directing his eyes all the time to right and left Without moving his head in the same direction (which would give rise to excessive 13,0v fatigue) involves the employmentof lenses which are very wide in the horizontal direction. Now looking obliquely acrossneutral lenses of the ordinary kinds gives rise to very 4serious visual troubles, more especially if the 3 5 lenses are not sufficiently large to permit vof vision-1n the most'pblique direction. This art of the invention consists in forming the enses with the maximum dimension called for in' the horizontal sense and so as to permit 4o nevertheless of the oblique visual rays passing without undergoing the slightest alterao tion. `These lenses when neutral have a uniform` thickness, as usual; but they are neither plane or spherical, but are of a curved orarched form, of which the curvature is in in Figs. 1,0, 11, and 12, in vertical section 'and plan View, respectively. For the better comprehension of this' part ofthe invention one may consider the neutral lenses as being cut, for example, from a cylindrical glass 'tuhe, the longerJI dimension of each lens extending circumferentially of the tube, while the narrow dimension extends in the direction 'of the 4axis of the tube. The lenses thus shaped the horizontal directiononly, as will be seen conform to the curvature of the eyeballs in the horizontal direction. They are traversed by the visual rays in a direction perpendicular to` the thickness of the lens', as well in horizontal oblique vision as in horizontal front vision, as can be seen by referring to Figs. 11 and 12. 'Hence obstacles onthe road on all sides appear vtothe driver in their real aspect, as they would if seen by ,lthe
naked eye. .f This new form of arched lens' is adapted for use by persons having abno'ri'nal vision of all kinds-eg., 'short-si hted, loing'- sighted, astigmatic, &c. Theari these lenses is more especially "adapted to form a basis -for the optical combination ed form of y whereby most kinds of abnormal vision may l be corrected.
