PROVISIONAL SPECIFICATION.
Improvements in Devices for Tightening Straps, Bands, or the like
after Buckling or Tying them, and for Slacking them Preparatory
to Unbuckling them.
I, FRANK LEDLIE MOORE, of Chatham, in the County of Morris and State
of New Jersey, U.S.A., Civil Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates in general to devices for tightening straps, bands, and the
like, after buckling or otherwise tying them, and for slacking them preparatory to
unbuckling or untying them, which devices usually comprise a straining lever
connected medially, as by a buckle, and also at one end of the strap so that when
swung over the strap will be taken up an amount equal to twice the distance between
said end and medial points, and a retaining device for securing the free end of said
lever to the strap. An example of such a strap fastener is shown and described in
my previous Letters Patent No. 12357.
The objects of my present invention are mainly to provide cheaper and better
means for attaching the strap to the hinged end of the straining lever, to avoid the
labor and expense of fastening the strap thereto by stitching, to provide for
fastening the hinged end of the straining lever to various points of the strap so as
to distribute the wear of the buckle on the perforated end of the strap, to simplify
and improve the retaining device for the free end of the straining lever and to
generally simplify, improve and reduce the cost of manufacture and application of
the strap fastener.
To attain these various ends, I, in accordance with my invention, attach the strap
to the hinged end of the straining lever by means of an attaching plate, which is
hinged to the straining lever and is by preference formed with a series of transverse
bars separated by slots through which the strap is closely woven in order to be
bound tightly to the plate, one of said bars being formed with a stud which is passed
through an aperture in the strap so as to additionally secure the strap at any desired
point to the plate and hence to the straining lever, and said plate being also formed
with a strap-keeper, to engage the free end of the straining lever which is secured
thereto by the strap.

Improvements in Devices for Tightening Straps, Bands, or the like
after Buckling or Tying them, and for Slacking them Preparatory
to Unbuckling them.
I, FRANK LEDLIE MOORE, residing at Chatham, in the County of Morris,
and State of New Jersey, one of the United States of America, Gentleman, do
hereby declare the nature of this invention and in what manner the same is to

page_text: be performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates in general to devices for tightening straps, bands and the
like, after buckling or otherwise tying them, and for slacking them preparatory to
unbuckling or untying them, which devices usually comprise a straining lever
connected medially, as by a buckle, and also at one end to the strap so that
when swung over the strap will be taken up an amount equal to twice the distance.
between said end and medial points, and a retaining device for securing the free
end of said lever to the strap.
The objects of my present invention are mainly to provide cheaper and better
means for attaching the strap to the hinged end of the straining lever, to avoid the
labour and expense of fastening the strap thereto by stitching, to provide for
fastening the hinged end of the straining lever to various points of the strap so as
to distribute the wear of the buckle on the perforated end of the strap, to simplify
and improve the retaining device for the free end of the straining lever and to
generally simplify, improve and reduce the cost of manufacture and application of
the strap fastener.
To attain these various ends, I, in accordance with my invention, attach the strap
to the hinged end of the straining lever by means of an attaching plate, which is
hinged to the straining lever and is by preference formed with a series of transverse
bars separated by slots through which the strap is closely woven in order to be
bound tightly to the plate, one of said bars being formed with a stud which is passed
through an aperture in the strap so as to additionally secure the strap at any desired
point to the plate and hence to the straining lever, and said plate being also formed
with a strap-keeper, to engage the free end of the straining lever which is secured
thereto by a strap.
I shall first describe in detail the mode in which I carry my invention into
practice, and then particularly point out its various features in the claims.
Reference is to be had to the accompanying drawing forming part of this
specification in which
Fig. 1 is a plan view of a strap fastener embodying my present invention after
buckling but before tightening.
Fig. 2 is a sectional side view of the same after buckling and tightening.
Like parts are designated by the same letters in both figures.
A designates the straining lever of the strap fastener illustrated, which is provided
with a medial buckle B of any kind, suitable for adjustably securing the free end C
of the strap to the straining lever.
For attaching and hinging the straining lever A to the end D of the strap I hinge
to the cross-bar E on the inner end of the straining lever, an attaching plate F,
consisting of parallel side bars G, connected by a plurality of cross bars H,
separated by slots I but slightly wider than the thickness of the strap, and I weave
the end D of the strap closely through the slots I as shown so as to bind the straps
to the plate tightly. One of the cross-bars H is formed with a stud J, which I pass
through an aperture in the strap so as to positively secure the strap to the plate F
and hence to the straining lever, and take up the slight strain left by the strap-
gripping bars H.
I also place a washer K on the stud J outside the strap and upset or rivet the
stud J thereon, where extra strength is required. With this construction the strap
may be quickly secured to the plate F, and may be readily shifted thereon, passing
the stud J through another aperture in the strap so as to bring another point of the
perforated free end of the strap to the buckle B, and thus distribute the wear of
the buckle on said end.
For securing the free end of the straining lever A to the strap after buckling
and swinging over to tighten the strap, I, in this case, form the outer end of the
plate F with a keeper L which engages the free end of the straining lever and
passes through a slot M formed therein, so that on passing the free end of the strap
through the keeper L over the end of the straining lever, the latter is securely

page_text: retained in place, and is automatically released, and the strap slackened, on with-
drawing the strap from the keeper L.
This form of retaining device for the straining lever renders the insertion of the
strap through the keeper extremely easy, and avoids an objection which has been
heretofore found to exist in similar contrivances.
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. In a strap-fastener of the character described, the strap attaching plate formed
with a plurality of cross-bars between its end cross bars, separated by a series of
slots narrowed so as to tighten grip the strap woven therethrough, and with a stud
on one of said cross-bars to enter an aperture in the strap, in combination with a
straining lever hinged to said strap attaching plate and carrying a strap buckle
intermediate its ends.
2. The strap-attaching plate formed with a strap receiving keeper and provided
with means for attachment to the strap, in combination with a straining lever hinged
to said attaching plate, carrying a strap-buckle intermediate its ends, and its end
adapted to engage said keeper and be secured thereto by the strap passing over it
and through said keeper.
3. The strap-attaching plate formed with a strap receiving keeper and provided
with means for attachment to the strap, in combination with a straining lever hinged
to said attaching plate, carrying a strap buckle intermediate its ends and formed
with a slot in its free end to receive the said keeper and be held down thereon by
the strap passing therethrough.
