page_text: I WILLIAM WILLOTT POPPLEWELL of the firm of Popplewell Colton & Co, of
17 & 18 Southampton Buildings London W () in the County of Middlesex, Patent
Agent do hereby declare the nature of this invention (communic ited to me by
Adolph Mathias Bechtold of Brooklyn, County of Kings, State of New York, USA
Optician) and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement
-
The object of my invention is to provide a spectacle of a construction having
temples adapted to hold the lenses properly before the eyes and to prevent undue
pressure of the bow on the bridge of the nose
The invention consists in the combination with the lenses or lens-frame, of temples,
each composed of a guide piece hinged to the outer end of each lens or lens-frame, a
collar fixed on the outer end of each guide piece and provided with an eye, an ear
wire passed through said collar and provided on its front end with a fixed collar
having an eye which slides on the guide piece and a spring coiled round the guide
piece between the fixed collar and loose eye on guide piece
In the accompanying drawings Figure 1 is a side view of a pair of spectacles
provided with my improved temple
Figure 2 is a similar view shewing the parts in a different position and parts
broken out
Figure 3 is an enlarged detail cross sectional view on the line x, x, Figure 1
Similar letters of reference indicate corresponding parts
My improved temple is composed of the guide piece A hinged at one end to a clip B
secured to the lens C, or to a hinged chip on the end of the lens frame, and of the eir
wire F The guide A is made square in cross section as shewn in Figure 3 and is
about from one to one and a half inches long On its swinging end the collar D is
fixed and from the same the eye E projects downwards
The front end of the ear
wire F is passed loosely through said eye E and its front end secured in a collar I
from the top of which the eye G projects upwards said oye having a squared
aperture in which the squared guide piece A fits correctly in such a manner that sud
eye can slide on the guide piece

page_text: A spring H is coiled round the guide piece between the eye G and the fixed
collar on the end of the guide piece
When the spectacles are in use, the bent spring ends F¹ of the ear wires Frost against
the backs of the ears in the usual manner and the bow of the spectacles rest upon the
bridge of the nose The springs H press the bow upon the bridge of the nose ind
keep said bow properly seated at all times, without requing the ear-wires to exert
any undue or painful pressure on the ears, as in the spectacles used heretofole
As shown, the guide piece A is arranged above the front end of the ear wie F but
it is evident that without departing from the spirit of this Invention, the end of the
ear wire may be arranged above the guide piece A or at the outer side of the same
It is also evident that the spring H inste id of encircling the guide piece A miy
encircle that part of the ear wire between the eye E and the collar I
As the guide piece A is square in cross section, the ear wire cannot swing on the
same and is thus at all times in the proper position As the spring is not covered
it can be reached very easily in case it becomes necessary to adjust or repair the
same In case an ear wire breaks it can easily be replaced by another
Having now particularly described and ascertained the nature of my sud inven-
tion and in what manner the same is to be performed I declare that what I
claim is -
First In spectacles the combination with a lens frame or lenses, of temples hinged
to the same each temple being composed of a hinged guide piece and a sliding
ear wire, collars provided with eyes secured on the guide piece and ear wires
respectively and a spiral spring surrounding the guide piece between said collars,
substantially as herein shown and described
Second In spectacles the combination with the lenses or lens frames, of a guide
piece hinged to the outer end of each lens or lens frame, which guide piece is
square in cross section, a collar fixed on the swinging end of each guide piece, an
eye formed on the bottom of each of said collars, an ear wire having its front end
passed through said eye, a collar fixed on the front end of each ear wire, an eye
with square aperture on said collar, through which sud square aperture the guide
piece is passed, and a spring coiled round the guide piece between the fixed collar and
moveable eye, on said guide piece, substantially as herein shown and described
