PROVISIONAL SPECIFICATION.
An Improved Buckle.
I, HENRY DALE of No. 11 Kensington Crescent in the County of Middlesex
formerly of No. 201 Great Portland Street in the County of Middlesex Mechanical
Inventor do hereby declare the nature of this invention to be as follows:-
1. My invention is for straps without holes and consists in making a buckle in
two parts, the said parts having a loose sliding connection and being formed and
arranged severally in manner following viz.:
"front bar "
of an "intermediate bar" and of a rear or "tail bar," the said three bars being
parallel with one another and suitably connected by side bars, the front and
intermediate bars being in a certain degree of proximity to one another hereinafter
explained.
2. One of the said parts (hereinafter called "part 1") consists of a
3. The other of the said two parts (hereinafter called "part 2") consists of a
holding bar or "inclined edge" having in immediate connection with it an "attach-
ment bar or plate" and also side portions extending from the latter outwardly so
that when the two parts are together they pass around the side bars of part 1 and
form between the two parts a loose sliding connection.
4. To ensure its effectiveness in operation the said holding bar or inclined edge
should be serrated and the outer side portions aforesaid made wide enough to afford
a comfortable hold for the fingers on each side of the buckle, in use as hereinafter
shewn.
5. The two parts when connected as aforesaid are arranged so that part 2 slides
between the tail and intermediate bars of part 1. The inclination of the inclined
edge being towards the tail bar of part 1.
6. The buckle is used as follows riz. :-One end of the strap being suitably
attached to the attachment bar or plate so that its tension will be towards the tail
bar, the other loose end is passed under the front bar over the intermediate bar and
part 2 and descends between the holding bar or inclined edge of that part and the
tail bar of part 1 so as to constitute an interlacement with the latter part and in
that interlacement covering the central portions of the buckle.
7. With such arrangement as above described the tension in opposite directions
of the strap ends causes a contraction of the holding bar or inclined edge and the
tail bar affording a secure and complete hold to the strap between them. For
adjustment purposes the holding bar or inclined edge is controlled from action by
the tension, by means of the outer side portions in connection therewith held with
one hand, whilst the strap is drawn through the buckle, interlaced as aforesaid
to the required position for fastening with the other hand. When let go and the
tension applied or allowed to take effect the fastening will be found secure and proof
against all tendency to slip or shift.
8. To ensure freedom for the strap to be drawn, when being adjusted, through
the buckle in manner aforesaid and at the same time to preserve the effectiveness
of the latter as a hold, it is necessary that the space between the front and inter
mediate bars of part 1 should be sufficiently in accord with the thickness of the strap
to which the buckle is applied as to allow the former to be drawn freely through
the buckle for the purpose of adjustment, at the same time when drawn in the
opposite direction by the tension to afford to the strap some grip by friction of part 1,
and also that the space occupied by part 2 between the intermediate and tail bars
of part 1, should leave sufficient space available in accord with the thickness
of the strap to enable it to be drawn through freely when the holding bar or
inclined edge is controlled as aforesaid.

page_text: 9. To unfasten or loosen, the buckle merely requires to be held by its outer
side portions aforesaid with one hand, as in fastening whilst the loose end of the
strap is pushed from under the tail bar with the other hand.
10. This buckle is designed for special uses viz.: Where a secure but not tight
fastening is required. Its special advantages consist of:-The nonnecessity of
disturbing the strap in the buckle, for ordinary adjustment it does not require
to be removed from under the tail bar and therefore its manipulation is reduced to
a minimum of simplicity. It is of peculiar neatness, simple in construction and
cheap to make.
11. The term "strap" is used throughout this description as one convenient for
the general purposes thereof only, and not in any sense as applying to or limiting
the general applicability and usefulness for special purposes as mentioned, of the
invention.

COMPLETE SPECIFICATION.
An Improved Buckle.
I HENRY DALE of No. 21 Kensington Crescent in the County of Middlesex
formerly of No. 11 Kensington Crescent aforesaid in the same County Mechanical
Inventor 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 improved buckle is designed for use with straps without holes and comprises
two main parts, the said parts having a loose sliding connection and being formed
and arranged as follows:-
One of the said parts (hereinafter called "part 1") comprises three bars viz., a
front bar an intermediate bar with roller and a rear or tail bar, parallel with one
another and suitably connected by side bars, to form a sort of frame the intermediate
bar being somewhat further from the front bar than from the rear or tail bar. The
other of the said two parts (hereinafter called "part 2") comprises a holding bar
having an inclined edge set in a direction to engage with the strap and prevent it
slipping. Parallel with this holding bar is an attachment bar or plate connected
therewith by side portions to which attachment bar one end of the strap is rivetted
or otherwise secured. The side portions of part 2 extend outwardly and are bent
down to pass around the side bars of part 1 thus forming between the two parts a
loose sliding connection.
In the accompanying drawings,
Fig. 1 is a plan of my improved buckle with one end of a strap connected
thereto.
Fig. 2 is a longitudinal section showing the ends of the strap held tightly in the
buckle.
a is the front bar, b is the intermediate bar provided with the roller c, d is the
rear or tail bar, and e e are the side bars connecting the ends of a, b and d. These
bars and the roller constitute what is herein referred to as part 1.
fis the holding bar having the inclined serrated edge f g is the attachment bar
or plate, and h h are the side portions connecting f and y these several parts con-
stituting what is herein called part 2. i, are the respective ends of the strap, the
former being connected to the attachment bar or plate and the other being the free
end which the buckle is designed to hold.
To ensure its effectiveness in operation the inclined edge of the holding bar may
advantageously be serrated as shown, and the outer side portions should be made
of sufficient size to afford a comfortable hold for the fingers on each side of the
buckle when the strap is being inserted or adjusted.
The two parts when connected as aforesaid are arranged so that part-2. slides

page_text: between the front and tail bars of part 1. The inclined edge is situate towards the
tail bar of part 1. The buckle is used as follows viz. :-One end i of the strap is
suitably secured to the attachment bar or plate so that the pull will be towards the
tail bar and passes over the intermediate bar or roller and down between it and the
holding bar. The strap is then passed round the article to be secured and its
loose end is passed under the front bar, over the whole of part 2 and descends
between the inclined edge of the holding bar of that part and the tail bar of part 1
so as to constitute an interlacement with the latter part and in that interlacement
covering the central portions of the buckle.
With such arrangement as above described tension in opposite directions on the
strap ends causes a movement of the holding bar or inclined edge towards the tail
bar, affording a secure and complete hold to the strap between them. For adjust-
ment purposes the holding bar or inclined edge is moved back by means of the
outer side portions in connection therewith, whilst the strap is drawn through the
buckle, interlaced as aforesaid, to the required position for fastening. When
released and tension applied or allowed to take effect, the fastening will be found
secure and will not slip or shift.
To ensure freedom for the strap to be drawn, when being adjusted, through the
buckle in manner aforesaid and at the same time to preserve the effectiveness of
the latter as a hold, it is necessary that the space between the front and inter-
mediate bars of part 1 should be sufficiently in accord with the thickness of the
strap to which the buckle is applied as to allow the former to be drawn freely
through the buckle for the purpose of adjustment, at the same time when drawn in
the opposite direction by the tension to afford to the strap some grip by friction of
part 1, and also that the space occupied by part 2 between the intermediate and
tail bars of part 1, should leave sufficient space available in accord with the thickness
of the strap to enable it to be drawn through freely when the holding bar or inclined
edge is controlled as aforesaid.
To unfasten or loosen, the buckle merely requires to be held by its outer side
portions with one hand, as in fastening whilst the loose end of the strap is pushed
from under the tail bar with the other hand.
This buckle is designed for use where a secure and heavy fastening is required.
Its advantages are that for ordinary adjustment it does not require to be removed
from under the tail bar and therefore its manipulation is rendered easy; it is simple
in construction, and cheap to make. A buckle suitable for uses where a light
fastening is required, forms the subject of another application for Letters Patent
No. 14834 dated 19th September 1890 filed by me concurrently with the present
application. The term "strap" is used throughout this Specification as one
convenient for the general purposes thereof only, and not in any sense as limiting
the general applicability and usefulness for special purposes as mentioned, of the
invention.
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 :-
The improved buckle made in two parts constructed and arranged substantially as
hereinbefore described.
