✓ Improvements in Joints for Spectacle Frames and other
Articles.
I, BENJAMIN IRVIN PRICE, of the City of Denver, in the County of Arapahoe;"
State of Colarado, United States of America, Optician, do hereby declare, the nature
of this invention, and in what manner the same is to be performed,, to be particularly.;
described and ascertained in and by the following statement:-
T
:-
My invention relates to improvements in joints to: spectacle frames and other
purposes and the object of my improvement is to provide a joint of few parts, simple.
and economical in construction, easily operated, efficient and durablo to which
ends my invention consists of the features and arrangements hereinafter described and
claimed...
In the drawing is illustrated an embodiment of my improvement, in which
drawing,
•
Fig. 1 is a top or plan view of the device with the temple and locking screw pin
removed:
r
Fig. 2, is a vertical section taken on the line -x Fig. 1 showing the temple and
screw pin in place :
Fig. 3 is a perspective view of the extremity of the temple adjacent to the bow
of the frame :
:
“
Fig. 4 is an elevation of the screw pin:
Fig. 5 is a plan view showing the same mechanism shown in Fig. 1 except that in.
Fig. 5 the bar is divided on a tortuous line while in Fig. 1 said bar is divided on a
zigzag or broken line:
Fig. 6 illustrates a solid bar similar in shape to the divided bar shown in
Figs: 1 and 5:
In these views let the reference numeral 1 indicate a bar composed of two sections
3 and 4 which may be formed by dividing a solid bar on the zigzag or broken
line 5: For the purposes of my invention line 5. may be curved as well as zigzag
or broken.
The bow 6 of the frame merges in or is continuous with the parts 3 and 4 of the
divided bar 1:
The outer extremity 10 of the bar 1, is cylindrical in shape as shown in Fig. 2.
The extremity 8 of the temple 7 is concavo-convex and fashioned to fit nicely, over
cylindrical part 10 of the bar 1: The curved extremity 8 of the temple is sufficiently"
open at 15 to allow the temple sufficient movement upon its bearing for-purposes
of adjustment.
The frictional contact of the temple upon its cylindrical bearing is always such as to
retain the temple in any desired position:---
The extremity 8 of the temple is provided with a slot 9 distinctly shown in
Fig. 3.
Bar 1 considered as integral is provided with a hole drilled nearly through its longi-
tudinal center for the reception of the screw pin 12.
In assembling the parts of the joint extremity 8 of the temple is slipped over the
cylindrical part 10 of bar 1. The pin 12 is then placed in position as shown in
Fig. 2, passing through slot 9 and securely connecting sections 3 and 4 of
bar 1.
When pin 12 is in position as shown in Fig. 2 it permits the necessary adjustment
of the temple 7 by turning its extremity 8. upon its cylindrical bearing, the slot 9
being of sufficient length for that purpose. The opening 15 of curved part 8 of the
temple should be somewhat less than half of a circle or small enough to prevent the
cylindrical part 10 from passing therethrough while the pin 12 prevents part 8 from
slipping from bearing 10 on a line at right angles to slot 9.

page_text: The pin 12 is itself held in position as shown in Fig. 2 by a few threads 13 cut upon
its upper portion next to the head of the pin, the upper part of the opening for
the screw in bar 1 being threaded to correspond with the threads 13 upon
the pin.
Though my improved joint is designed more particularly for use in spectacle frames,
I do not limit myself to its use for that purpose as I am aware that it may be used in
many other connections and relations.
:
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is
".
First. In joints for spectacle frames the bar 1 composed of sections 3 and
4, the shape of the contact surface of these sections being indicated by the
zigzag or broken line 5, the bar thus formed being provided with the cylindrical
bearing 10 and an opening for a pin as described, the temple 7 provided with a concavo-
convex extremity 8 having a slot 9, and the pin 12 provided with threads 13, these
elements being arranged and connected, substantially as described.
Second. A bar divided on the tortuous line 5 into two sections 3 and 4 and termi-
nating at one extremity into the cylindrical bearing 10, the two sections being united.
by a suitable locking pin, substantially as described.
Third. In a joint the coinbination of the solid bar 1 provided with the cylindrical
part 10, a concavo-convex part 8 provided with a slot 9 and adapted to fit nicely upon
cylindrical part 10, and locking pin 12, the bar 1 being provided with an opening for
the reception of said pin, substantially as described.
Fourth. In a joint for spectacle frames the bar 1 composed of sections 3 and 4, the
shape of the contact surfaces of these sections being indicated by a zigzag or broken
line, the bar thus formed being provided with the cylindrical bearing 10 and an
opening for a locking pin as described, the temple 7 provided with a concavo-convex
extremity having a slot 9, and a suitable locking pin all arranged and connected, sub-
stantially as described..
Fifth. A bar divided on the zigzag or broken line 5 into two sections 3 and 4 and
terminating at one extremity in the cylindrical joint bearing 10, the two sections being
united by a suitable locking pin, substantially as described.
Sixth. In a joint for spectacle frames the bar 1 composed of sections 3 and 4, the
shape of the contact surface of these sections being indicated by a tortuous line 5, the
bar thus formed being provided with a cylindrical bearing 10, a temple 7 being
provided with a concavo-convex extremity having a slot 9, sections 3 and 4 being
united by a suitable locking pin, substantially as described.
