Improvements in Eye-glasses.
1, ALBERT SCRANTON WEAVER, of 1151 Chalkstone Avenue, in the City of
Providence, County of Providence, and State of Rhode Island, United States of
America, Optician, do hereby declare the nature of my invention, and in what
manner the same is to be performed, to be particularly described and ascertained
n and by the following statement:-
This invention has reference to improvements in what are known as spring-bar
eye-glasses in which the nose-bridge is made in two parts which are connected to a
horizontal bar on which they slide, so that the glasses are adjusted on a horizontal
blane.
The object of the invention is to secure greater strength and economy in
construction.
Another object of the invention is to provide a flexible and automatically-
adjustable cushion bearing on the nose.
The invention consists in the peculiar and novel construction which will be more
fully described hereinafter and pointed out in the claims.
Figure 1 is a side view of a pair of eye-glasses provided with my improved
spring-biidge and nose-cushions.
Figure 2 is a top view of the same.
Figure 3 is a vertical sectional view showing one bridge-piece with its nose-
cushion.
Figure 4 is a view of the bar blank, and
Figure 5 a sectional view of the bar.
Figure 6 is a view of the blank from which one-half of the bridge is made.
Figure 7 is an edge view of the blank shown in Figure 6 after the same is bent
to form one-half of the bridge.
Figure 8 is a perspective view of one of the nose-cushions.
Figure 9 is a view of a modified form of the bar 18, and
Figure 10 a view of a modified form of the blank shown in Figure 6.
Similar numerals of reference designate corresponding parts throughout.
In the drawings 10-10 indicate the rims of the lenses, 11-11 the post secured to
the rims and projecting therefrom to which the bridge-pieces are fastened in the
usual manner by means of the screws 12. Each half of the bridge is made of one
piece of metal stamped out by suitable dies into the blank shown in Figure 6,-on
this blank the part 13 forms the rod around which the spiral-spring 14 is placed,
15 the upper bearing, 16 the lower bearing, and 17 the recess into which the bar 18
enters, 19 forms the bent portion of the bridge and 20 the support for the nose-
cushion on the upper and lower ends of which the pintles 21-21 are formed on
which the frame of sheet-metal 22, having the bent-over perforated ends 211
and provided with the cushion 23, is pivotally connected. The bar 18 is formed
by stamping the blank, shown in Figure 4, from sheet-metal and bending up the
perforated ends 24.
In associating the parts neither skilled labor nor mechanical knowledge is
required. The blank shown in Figure 6 is bent either to the right or left, it is
then inserted into the slot 18' of the bar 18, the spiral-spring 14 is placed over the
rod 13 the end of which is passed into the hole of the end 24 of the bar 18, the
ends 21 are sprung so as to pass over the pintles 21 and thus the nose-cushions are
secured, when the bow is secured to the posts 11 by the screws 12 in the usual
[Price 1

page_text: manner; the whole forming a strong yet light and durable bridge for eye-glasses,
automatically adjustable, that can be manufactured and sold for less money than
spring-bar eye-glasses as heretofore constructed.
My improved spring-bar bridge is applicable to lenses without rims in which the
posts are secured to the glasses direct.
The bar 18 instead of being slotted may be made with a central abutment 182, as
shown in Figure 9, and the blank, instead of having the two opposite recesses 17,
be provided with the hole 17', as shown in Figure 10, and these parts may be
arranged and connected in the same manner as above described.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
Claim 1. In spring-bar eye-glasses, the combination with the two lenses and the
posts, of two bent metal-blanks each comprising a support for the nose-cushion
and a spring-supporting bar, and a bar provided with ways for the bridge-pieces
and abutments for the coiled-spring; the whole adapted for automatic adjustment,
as described.
2. In spring-bar eye-glasses, the combination with the two lenses and the posts,
of the adjustable bridge-connection consisting of a bar provided with ways and
bent-up perforated ends, two bent metal-blanks each comprising in one piece the
support for a nose-cushion, the recesses 17 and the rod 13, and the coiled-springs 14
each abutting against a bent-up perforated end of the way-bar and the recessed
portion of the blank, as described.
3. In spring-bar eye-glasses, the combination with the lenses and the posts 11,
of the bar 18 provided with the bent-up perforated ends 24, the two beut
metal-blanks each forming in one piece the spring-supporting rod 13, the recesses 17,
the bent portion 19 and the supports for the nose-cushion, of the nose-cushions 23,
and the coiled-springs 14; the whole adapted for automatic adjustment, as
.described.
Dated this 23rd day of May A.D. 1895.
