Year: 1884

page_text: I WILLIAM WEST of N° 42 Caroline Street Birmingham in the County of
Warwick Manufacturing Jeweller do hereby declare the nature of the said
Invention for "A NEW OR IMPROVED SCARF RING" to be as follows:-
My Invention consists of a new or improved scarf ring the parts of which are
constructed and combined in the manner hereinafter described.
By my Invention the fastening and releasing of the scarf are effected with great
facility and the fastened scarf is held very securely in its place in the ring.
I make the scarf ring of two parts namely of a bow shaped front part and a bow
shaped or straight back part the latter part being made capable of sliding towards
or from the front part the convex side of the back part when the back part is bow
shaped being presented to the concave side of the front part and being nearly
parallel thereto. Between the sliding back part and the front part the scarf is
gripped or released in the following manner. Fixed to the concave face of the
front part of the scarf ring is a bow spring having the same configuration as but
longer than the said front part the ends of the spring extending beyond the ends
of the said front part but the ends of the spring may be encased in the front part
instead of projecting from it. The projecting or encased ends of the spring are
corrugated or toothed. In each end of the sliding back part is a slot which slots
work upon the corrugated or toothed ends of the bow spring. The cross bars at
the outer ends of the slots constitute cross teeth which engage with the corrugated
or toothed ends of the spring the elasticity of the free ends of the spring retaining
the sliding back part of the scarf ring in the position to which it has been adjusted.
The sliding back part is prevented from being detached from the front part by
enlargements at the extreme ends of the toothed portions of the spring or by
passing the ends of the toothed portions of the spring through slots in the covering
or encasing ends of the front part of the scarf ring.
By compressing the free ends of the bow spring which motion is permitted by
the slots in the ends of the back part of the scarf ring the said back part is released
from the toothed ends of the front part and may be moved backwards without
slipping over the said toothed ends. To increase the grip of the back part upon
the scarf it may be scolloped or have an undulating figure given to it.
In using the scarf ring it is opened to its full extent that is the sliding back
part is moved from the front part to the extent permitted by the toothed ends of

page_text: the spring. The scarf ring having been adjusted on the scarf the sliding back part
is pressed inwards so as to cause it to grip the scarf between itself and the front
part the cross teeth or bars of the back part slipping over the corrugated or toothed
ends of the spring the elasticity of the said spring retaining the sliding back part
in its fastening position.
To unfasten the scarf ring the toothed ends of the spring are pressed inwards.
The sliding back part is thereby unfastened and is free to take its open position
when the scarf ring is withdrawn from the scarf.

page_text: I WILLIAM WEST of N° 42 Caroline Street Birmingham in the County of
Warwick Manufacturing Jeweller, do hereby declare the nature of my Invention
for "A NEW OR IMPROVED SCARF RING" and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:
My Invention consists of a new or improved scarf ring, the parts of which are
constructed and combined in the manner herein after described.
By my Invention the fastening and releasing of the scarf are effected with great
facility and the fastened scarf is held very securely in its place in the ring.
I make the scarf ring of two parts namely of a bow shaped front part and a bow
shaped or straight back part, the latter part being made capable of sliding towards
or from the front part, the convex side of the back part, when the back part is bow
shaped, being presented to the concave side of the front part and being nearly
parallel thereto. Between the sliding back part and the front part the scarf is
gripped or released in the following manner.
Fixed to the concave face of the
front part of the scarf ring is a bow spring having the same configuration as but
longer than the said front part, the ends of the spring extending beyond the ends
of the said front part, but the ends of the spring may be encased in the front part
instead of projecting from it. The projecting or encased ends of the spring are
corrugated or toothed. In each end of the sliding back part is a slot which slots
work upon the corrugated or toothed ends of the bow spring. The cross bars at
the outer ends of the slots constitute cross teeth which engage with the corrugated
or toothed ends of the spring, the elasticity of the free ends of the spring retaining
the sliding back part of the scarf ring in the position to which it has been adjusted.
The sliding back part is prevented from being detached from the front part by
enlargements at the extreme ends of the toothed portions of the spring, or by
passing the ends of the toothed portions of the spring through slots in the covering
or encasing ends of the front part of the scarf ring.
By compressing the free ends of the bow spring, which motion is permitted by
the slots in the ends of the back part of the scarf ring, the said back part is
released from the toothed ends of the front part and may be moved backwards
without slipping over the said toothed ends. To increase the grip of the back
part upon the scarf it may be scolloped or have an undulating figure given to it.
In using the scarf ring it is opened to its full extent; that is, the sliding back
part is moved from the front part to the extent permitted by the toothed ends of
the spring. The scarf ring having been adjusted on the scarf the sliding back part
is pressed inwards so as to cause it to grip the scarf between itself and the front
part, the cross teeth or bars of the back part slipping over the corrugated or
toothed ends of the spring, the elasticity of the said spring retaining the sliding
back part in its fastening position.
To unfasten the scarf ring, the toothed ends of the spring are pressed inwards.
The sliding back part is thereby unfastened and is free to take its open position
when the scarf ring is withdrawn from the scarf.
Figure 1 of the accompanying Drawing represents in front elevation and Figure 2
in side elevation a scarf ring made according to my Invention in which the
corrugated or toothed ends of the bow spring project beyond the ends of the front
part of the ring; Figure 3 represents a back elevation; Figure 4 a longitudinal
section and Figure 5 a transverse section of the scarf ring partly opened; Figure 6

page_text: represents in side elevation and Figure 7 in end elevation the scarf ring opened to
its full extent; Figure 8 represents the front part of the scarf ring detached;
Figure 9 the bow spring detached and Figure 10 the sliding back part detached.
The scarf ring is drawn double the full size for the purpose of the better
exhibiting its construction and action.
The same letters of reference indicate the same parts in the several Figures of
the Drawing.
a is the front part of the scarf ring and b the sliding back part, between which
parts a and b when closed upon one another the scarf is gripped; c is the bow
spring rivetted at its middle to the concave face of the front part a, the said bow
spring being longer than the front part. The projecting ends c2, c2 of the
bow spring c are corrugated or toothed as represented and pass through the
slots b, be in the ends of the sliding back part b. The cross bars 63, 63 at the outer
ends of the slots b² 62 constitute cross teeth which engage with the corrugated or
toothed ends c², c² of the bow spring c the elasticity of the free ends of the bow
spring retaining the sliding back part in the position to which it has been
adjusted. The sliding back part b is prevented from being detached from the front
part a by the enlarged ends e, e of the toothed portions of the spring.
When the toothed ends c², c², of the bow spring c are in their normal positions.
the cross bars or teeth 63, 63 of the sliding back part b engage with the said toothed
ends and the said sliding part b is thereby prevented from moving backwards to
open the scarf ring but the said cross bars or teeth 6s, 6s can slip over the teeth of
the said toothed ends for closing the scarf ring when the said back part b is pushed
inwards. By compressing the toothed or corrugated free ends c², c² of the bow
spring between the thumb and finger, as indicated by the arrows in Figure 6, the
said free ends approach one another as indicated by dotted lines in Figure 4, the
Baid motion of the free ends being permitted by the slots 62, 62 in the back part b
through which they pass. The said back part b is thereby released from the
toothed ends c², c² and may be moved backwards to open the scarf ring without
slipping over the said toothed ends.
In using the scarf ring it is opened to its full extent by sliding the back part b
into the position represented in Figures 6 and 7. The position of the scarf ring
having been adjusted on the scarf the sliding back part b is pressed inwards as
represented in Figures 2 and 4 so as to cause it to grip the scarf between itself and
the front part a, the cross teeth or bars 63, 63 of the back part b slipping over the
corrugated or toothed ends c², c² of the bow spring c the elasticity of the said spring
retaining the sliding back part b in its fastening position.
To unfasten the scarf ring the toothed ends c2, c³ of the bow spring care pressed
towards one another as indicated in Figure 4. The sliding back part 6 is thereby
unfastened and is free to take its open position Figures 6 and 7 which may be
effected by the act of withdrawing the scarf from the ring.
Figure 11 represents in front elevation; Figure 12 in side elevation closed ;
Figure 13 in back elevation and Figure 14 in longitudinal section, open, a scarf
ring constructed according to my Invention in which the toothed or corrugated
ends of the bow spring are encased in the front part instead of projecting from it;
Figure 15 represents in edge view and cross section the said scarf ring; Figure 16
represents in longitudinal section and plan the front part of the scarf ring;
Figure 17 in side elevation the bow spring and its sliding back part; Figure 18 in
front elevation the sliding back part and Figure 19 in front elevation the bow
spring In Figure 14 the sliding back part is represented released or disengaged
from the toothed ends of the bow spring by the pressing together of the said
toothed ends.
In this arrangement the bow spring is not rivetted to the front part but is
retained in its place by the extreme ends c³, c3 of the toothed parts c², c2 being
passed through the slots a², a² in the ends of the front part a and the said ends
bent downwards in addition to the said ends being passed through the slots in the
liding back part b.

page_text: The action of this arrangement of my Invention is the same as that first described
and corresponding parts are marked with the same letters of reference. Instead of
making the toothed or racked ends of the bow spring of angular corrugations for
the cross teeth or bars of the sliding back part to engage with, a rack consisting of
a series of holes in the ends of the bow spring and studs on the cross bars of the
sliding back part may be used as represented in Figures 20 and 21, Figure 20
showing the bow spring in perspective and Figure 21 a plan and section of the
back part separately. The rack is marked c and the studs on the back part b
engaging with the rack are marked b³.
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 a scarf ring, a sliding back part, between which and the front part of
the scarf ring, the scarf is gripped or released, in combination with mechanism for
retaining the said sliding back part in the position to which it has been brought
substantially as herein before described and illustrated in the accompanying
Drawing.
Secondly-The combination in a scarf ring, of a bow spring having toothed or
racked ends or other analogous retaining appliances, and a sliding slotted back
part engaging with and being retained by the said toothed or retaining appliances
whether the said toothed racked or retaining ends of the bow spring be made to
project from the ends of the front part or be encased in the said front part the
several parts of the scarf ring being constructed and acting substantially as herein
before described and illustrated in the accompanying Drawing.
Dated this Seventeenth day of July 1884.
