"IM-
My Invention relates to swivels or fastenings for connecting together straps,
bands, chains, or other articles, and for carrying articles, so as to admit of their
being readily disconnected or released, and it consists in providing the hinged or
moveable tongue which forms a portion of the connecting or holding eye of the
swivel with a projection or projections, for the purpose of facilitating the operation
of moving the tongue and exposing the hooked portion of the eye for the insertion
or release of another eye or loop which is to be attached or removed as the case
may be. A purchase is thus obtained for the thumb or finger in the act of
operating the tongue, whereby the pain and inconvenience attending the ordinary
method of moving the tongue by the direct pressure of the thumb or finger thereon
are entirely. obviated.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by

PROVEMENTS IN SWIVELS."
My said Invention relates to swivels or fastenings for connecting together straps,
bands, chains, or other articles, and for carrying articles so as to admit of their
being readily disconnected or released, and it consists in providing the hinged or
moveable tongue, which forms a portion of the connecting or holding eye of the

of moving the tongue and exposing the hooked portion of the eye for the insertion
or release of another eye or loop which is to be attached or removed as the case
may be.
The projection may be arranged in various ways whilst still enabling the same
object to be accomplished. The two Figures on the accompanying Sheet of
Drawings illustrate respectively on an enlarged scale two modifications of swivels
constructed and arranged in accordance with my Invention. Similar letters indicate
like parts in both the Figures.
a is the eye of the swivel; b, the hinged tongue; c, the projection formed
thereon. This projection in the arrangement, Figure 1, is so formed as to jut out
from the exterior of the tongue b, whilst in the modification, Figure 2, it is mado of
a looped shape so as to encircle the cyo a'. The operation is similar in both cases,
by the act of pressing upon the end c of the projection c the tongue b is moved
inwards into the position indicated by dotted lines, thereby exposing the booked
-portion a¹ of the eye a for the insertion of another eye or loop, or if another eye
or loop has been inserted for its release as occasion may require. By means of this
Invention a purchase is obtained for the thumb or finger in the act of operating the
tongue, whereby the pain and inconvenience attending the ordinary method of
moving the tongne by the direct pressure of the thumb or finger thereon are
entirely obviated.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried into
effect, I would observe in conclusion that what I consider to be novel and original,
and therefore claim as the Invention secured to me by the by the herein-before
in part recited Letters Patent is constructing the tongue of the swivel eye with a
projection or projections for the purpose of more readily opening the same, sub-
stantially as herein-before described.
In witness whereof, I, the said Josiah Burke Lynch, havo to this my Speci-
fication set my hand and seal, the Eighth day of July, One thousand eight
hundred and seventy-six.
