Improvements in Buckles.
I, GEORGE MILLER AYLSWORTH of 30, Third Street, Collingwood, in the
County of Simcoe, Province of Ontario, and Dominion of Canada, Physician, do
bereby declare the nature of this invention to be as follows:-
My invention relates particularly to harness buckles. The frame of the buckle
is formed of a sheet metal blank whose edges are bent oppositely and in the same
direction at right angles to the intervening flat portion or web piece of the frame.
The wings that are thus produced are preferably rounded on the edges at each end
and slope or diminish in height from one to the other end of the frame and at
a point near the end where the wings are of greatest height the wings have
opposite perforations for the reception of a transverse pintle that when engaged
by other parts hereafter described is rivetted or otherwise secured by its ends
to the wings through which it extends. A keeper preferably a sheet metal plate
is an essential portion of the buckle. This consists of an elongated flat piece
of plate metal parallel on the side edges and notched on one end at opposite
corners to reduce the width of an end portion of the plate which part is then
bent into scroll form of a size diametrically which will allow the scrolled end to
be placed upon a transverse pintle and loosely fit the same, so that the keeper
plate and frame of the buckle will have a hinged connection. There is a tongue
at the transverse centre and near the free end of said keeper which projects at
right angles to the part it is affixed to and is of sufficient length to have a
locking engagement with an opposite perforation in the web-plate of the frame.
Upon the pintle coiled wire springs are placed, said springs occupying the portions
of the pintle that are not embraced by the scroll, there being an integral loop
produced between the two spring coils which loop rests upon the upper surface
of the keeper plate. The outer ends of the coiled springs are secured in the
wings at opposite points and the springs are wound upon the pintle so as to cause
the loop portion to press the keeper plate toward the web of the frame of the
buckle. The buckle is attached upon a portion of the harness which is to be
secured to another part of the same, preferably by rivets passing through aligning
perforations in the web-plate of the buckle frame and a strap whereon the buckle
is to be affixed the end portions that project beyond the latter having washers
placed upon them and affixed in place by rivetting, as usual.
The improved buckle is adapted for use to connect two flat lapped straps or
to produce a loop at the end of a rein or other strap or adjustably join a single
strap with two angularly diverging straps. Preferably the strap perforations
which are to be interlocked removably with the tongue of the buckle are pro-
tected with eyelets which will prevent injury to the straps and facilitate the
adjustment of the buckle.
In using this improved buckle to form a loop on a strap end, the free end
portion of the strap is folded towards the beel of the buckle and inserted between
the frame web plate and the scroll of the keeper plate for which sufficient space
is provided, and the keeper plate that is at the same time raised so as to permit
the strap end to pass freely through the frame is released when the tongue is
opposite the proper hole in the inserted portion of the strap. The spring pressed
keeper plate will project the attached tongue through the hole in the strap it
is opposite and also through the aligning perforation in the web plate of the
buckle frame so that there will be a secure interlocking connection of the folded
parts of the strap produced. When the overlapping end portions of two straps
are to be connected, the buckle is rivetted or otherwise secured upon one strap

page_text: near its end and the other strap end having spaced perforations in it is inserted
through the buckle frame from the heel or scrolled end of the keeper plate,
the connection of the tongue with a perforation in the inserted strap being effected
as has been already explained.
The improved buckle in all cases where used obviates the need for a keeper
loop on the strap to secure, the end of the strap from flapping as the keeper plate
of the buckle is adapted to press the parts of the strap together and render a
loop unnecessary.

COMPLETE SPECIFICATION.
Improvements in Buckles.
I, GEORGE MILLER AYLSWORTH of 30, Third Street, Collingwood, in the
County of Simcoe, Province of Ontario, and Dominion of Canada, Physician, 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:-
My invention relates to improvements in buckles, and particularly to such as are
used to adjustably connect parts of harness for draught animals, the objects being to
provide a buckle which is of simple and cheap construction, which is reliable in
service, which is convenient to adjust for an attachment or release of parts it
connects, and which is of general utility as a harness buckle.
To these ends my invention consists in the peculiar construction and combination
of parts, as is hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming a part of this
Specification, in which similar letters of reference indicate corresponding parts in
all the figures.
Figure 1 is a top view of the buckle connected to a strap which is folded to
produce a loop and the lapped parts secured together by the buckle.
Figure 2 is a longitudinal partly sectional view of the looped strap and improved
buckle, on the line 2-2 in Figure 1.
Figure 3 is a top view of the improved buckle applied to parts of harness, so as
to adjustably connect two diverging straps to another strap, and
Figure 4 is a side view of the buckle attached to a strap end and adjustably
connected to another strap end portion.
The frame A of the buckle is formed of a sheet metal blank cut to shape by
proper mechanism and then bent at a a oppositely and in the same direction at
right angles to the intervening flat portion or web piece of the frame. The wings b
that are produced by bending the frame blank as stated are. preferably rounded on
the edges at each end, as shewn in Figure 4, and slope or diminish in height from
one end of the frame toward the other end. At a point near the frame end where
the wings barc of greatest height from the web piece, opposite perforations are
formed in the wings for the reception of a transverse pintle c, that when engaged
by other parts that will be described is rivetted or otherwise secured by its ends to
the wings through which it extends.
A preferably sheet-metal keeper plate C is an essential portion of the buckle,
and consists of an elongated flat piece of plate metal parallel on the side edges and
notched on one end at opposite corners to reduce the width of an end portion of the
plate, which part d is then bent into scroll-form of a size diametrically which will
allow the scrolled end to be placed upon the transverse pintle c and loosely fit the
same, so that the keeper plate and frame of the buckle will have a hinged con-
nection produced by the pintle when said parts are assembled. There is a tongue e

page_text: preferably formed of a rivet, inserted through a perforation in the keeper plate C
and secured thereto by its head at the transverse centre, and near the free end of
said keeper, which tongue projects at right angles to the part it is affixed upon
and is of sufficient length to have a locking engagement with an opposite perfora-
tion in the web-plate of the frame A, as indicated in Figure 2. Upon the pintle c
the coiled wire springs 9 are placed, said springs occupying the portions of the
pintle that are not embraced by the scroll d, there being an integral loop g¹
produced between the two spring coils, which loop rests upon the upper surface of
the keeper plate C. The outer ends of the coiled springs g are secured in the
wings bat opposite points, and the springs are wound upon the pintle so as to
cause the loop portion g' to press the keeper plate C toward the web of the buckle
frame.
The completed buckle is attached upon a portion of the harness which is to be
secured to another part of the same, preferably by rivets as at 1, these passing
through aligning perforations in the web-plate of the buckle frame and a strap
whereon the buckle is to be affixed, the end portions that project beyond the latter
having washers placed upon them and affixed in place by rivetting, as usual.
The improved buckle is adapted for use to connect two flat lapped straps E, as
shewn in Figure 4, or to produce a loop at the end of a reign or other strap D, as
represented in Figures 1 and 2, or adjustably join a single strap B with two
angularly-diverging straps B¹, as indicated in Figure 3. Preferably the strap
perforations which are to be interlocked removably with the tongue e of the buckle
are protected with eyelets, as at n, which will prevent injury to the straps and
facilitate the adjustment of the buckle.
It will be seen that to form a loop on a strap end which is provided with one of
the improved buckles, the free end portion of the strap, such as D in Figures 1
and 2, is folded toward the heel of the buckle and inserted between the frame
web-plate and the scroll d of the keeper plate, space being provided to allow such
an insertion. The keeper plate that is at the same time raised so as to permit the
strap end to pass freely through the frame A, is released when the tongue e is
opposite the proper hole n in the inserted portion of the strap. The spring-
pressed keeper plate C will project the attached tongue e through the hole in the
strap it is opposite and also through the aligning perforation in the web-plate of
the buckle frame so that there will be a secure interlocking connection of the
folded parts of the strap D produced. When the end portions of two straps E
are to be connected, as represented in Figure 4, the buckle is rivetted or
otherwise secured upon one strap near its end and the other strap end, having
spaced perforations in it, is inserted through the buckle frame from the heel or
scrolled end of the keeper-plate C, the connection of the tongue e with a perfora-
tion in the inserted strap being effected as has been already explained. The
improved buckle in all cases where used, obviates the need for a keeper loop on
the strap to secure the end of the strap from flapping, as the keeper plate C of
the buckle is adapted to press the parts of the strap together and render a loop
unnecessary.
It is claimed for the improved buckle that it is very light, neat in appearance,
strong and efficient in service, and convenient to adjust as it dispenses with much
of the handling that is necessary to release straps connected with buckles of
ordinary form.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is-
1. The combination, with a buckle frame having side wings, a flat web-plate
between the wings, and a transverse pintle seated at its ends in the wings, of a
keeper-plate having a scroll and embracing said pintle, a spring on the pintle
pressing on said scrolled end of the keeper plate, and a tongue projecting at a

page_text: right angle from the keeper plate and entering a perforation in the web plate of
the buckle frame, substantially as described.
2. The combination, with a buckle frame formed of sheet metal having opposite
wings and an intervening web-plate and a transverse pintle secured at its ends in
the wings, of a keeper-plate having a scrolled end embracing the pintle, coiled
springs on the pintle between the wings and the scrolled end of the keeper plate,
an integral loop connecting the springs and pressing on the keeper plate, the ends
of the springs engaging the frame wings, and a tongue on the keeper-plate
adapted to penetrate a perforation in the web-plate and enter a hole in a strap
passed between the web-plate and keeper plate, substantially as described.
