Street E.C. do hereby declare the nature of this invention to be as follows:-
To make an improved buckle or fastening for straps, cords, braces, belts, bands and
other similar articles. For this purpose we make a frame of brass, iron, or other
suitable material with an oblong hole cut transversely at one end, the strap or other
article will pass through the hole as usual, we place on the frame a plate or wedge
made to slide up and down, we also have an eccentric or snake wheel or cam made to
turn on a pivot and force the sliding plate or wedge against the loose end of the strap
or other article thus pressing the latter tightly against the frame and holding it there
until released by reversing the wheel or cam, the eccentric wheel will be covered and
moved by a circular plate attached to it which plate will have a groove cut in its
underneath side which will draw the sliding plate back by means of a stud fixed to
the upper part of the latter and working in the said groove, a lock can be made in
the buckle if required, which will shoot a bolt out with teeth in it, corresponding
teeth being cut in the snake wheel, thus preventing it from being turned when
locked.
The buckle or fastening can also be made with a band of metal or other suitable
material being fixed over a hole cut transversely in the plate above mentioned high
enough for the strap or other article to pass underneath, the upper part of this band
will have a lever or thumbscrew passing through it attached to a plate or wedge
which when screwed down will force the strap into the hole or indentation beneath
and hold it firm until released by reversing the screw or lever.

Improvements in Buckles or Fastenings for Straps, Cords, Braces,
Belts, Bands, and other similar Articles.
We, ALFRED WATSON, of 119, Whitwell Road, Plaistow, in the County of Essex,
and NATHANIEL BUXTON, of Dunedin House, Basinghall Avenue, Basinghall Street,
in the City of London, Commission Agents, 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 :-
Our invention relates to improvements in brekles or fastenings for straps, cords,
braces, belts, bands and similar articles, the object of our invention being to provide
an improved buckle or fastening which will pos tively clip the strap, band or the like
and securely hold it. A buck e or fastening constructed according to our invention

page_text: comprises a gripping piece which is adapted to be moved relatively with a slot
through which the end of the strap or the like to be held is passed, the said movable
piece being operated mechanically.
According to one arrangement the gripping piece slides in a frame and forms one
side of a slot through which the end of the strap is passed, the said gripping piece
being moved to hold the strap or the like by means of an eccentric plate.
According to another arrangement the movable piece is arranged to be operated by
means of a screw over an opening or recess in the frame.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is a side elevation of a buckle or fastening constructed according to our
invention and applied to a strap, the said buckle or fastening being of the kind
wherein the movable piece is moved by an eccentric or cam:
Figure 2 is a section of the part shewn in Figure 1:
Figure 3 is a sectional side elevation:
Figure 4 is a section on the line 4-4 Figure 2:
Figure 5 is a plan of the buckle or fastening with the operating cam removed :
Figure 6 is a sectional view of the said cam detached; and,
Figure 7 is an underside view of the same:
Figure 8 is a plan shewing the arrangement wherein the movable piece is operated
by a screw over an opening:
Figure 9 is a sectional side elevation of the same; and,
Figure 10 is a section on the line 10-10 of Figure 8:
Figures 11 and 12 are views illustrating a further modification and hereinafter
described.
Similar letters of reference indicate corresponding parts in the several figures.
a is the base plate or frame of the buckle and is the sliding piece for gripping
the strap or the like. c is the device for operating the said gripping piece.
In the arrangement of our invention shewn in Figures 1 to 7, the frame a has the
sliding piece 6 moving within it, the side bars of the said frame having dove-tailed or
V-grooves as indicated at d, d Figures 4 and 5 in order to retain the said movable
plate in position in the frame, whilst at the same time permitting of this movement.
The operating device c is in the form of a disc e pivoted upon a bridge piece of the
frame and having on its underside a cam surface 9 which bears against the rear
edge of the gripping piece b, as clearly shewn in Figure 3. In connection with the
cam surface g is a cam groove which engages with a pin i on the top of the said
plate, the said groove h and pin i serving for drawing the gripping piece backwardly
in the frame whilst the cam surface g serves for moving it forward. The top of
the disc e is provided with finger pieces j, j for enabling the disc to be manipulated.
It will be understood that the fastening constructed as herein before described is at
one end permanently attached to the strap which is indicated in the drawings by the
letter k. In order to fix the other end of the strap the latter is passed through the
space between the frame a and the gripping piece b as clearly shewn in Figures 1, 2
and 3 and then the clamping device is rotated in order to force the gripping piece b
into close contact with the said strap. m is a stirrup or loop arranged upon the
frame a for confining the free end of the strap over the buckle as shewn in Figure 3.
In the modification of our invention shewn in Figures 8 to 10 the movable gripping
plate b instead of being arranged to clamp the strap between itself and the end of the
frame is arranged to clamp it against the bottom of the frame and the operating
device c is in the form of a screw which is introduced through the bridge piece,
and carries the piate at its lower end. An opening of slightly larger size than the
gripping piece 6 is formed in the frame beneath the plate b so that when the strap
is passed between the said gripping piece band the frame it can be securely held by
screwing down the screw c so as to more or less force a portion of the strap k into
the opening n in a manner which will be readily understood by reference to
Figures 9 and 10. The opening n need not pass right through the plate but may
consist of a recess.

page_text: Instead of forming the opening n in the frame beneath the plate the said plate
may be hollowed out on its underside and a corresponding protuberance formed
upon the frame in a manner which will be clearly understood by reference to
Figures 11 and 12 which are respectively longitudinal and transverse sections of
the said modified fastening.
It will be obvious that instead of operating the plate b by means of a screw it
may be operated by a lever.
In combination with the arrangements illustrated in Figures 8 to 12 we advan-
tageously employ a metal loop o through which the end of the strap is passed
after passing beneath the plate b. By turning the strap end into the position shewn
in dotted lines in Figure 9 great power can be exerted to tighten the strap before
fixing the screw 6 the portion of the strap carrying the said loop being reinforced
by an additional strap p to prevent buckling under the strain.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
1. A buckle or fastening wherein a gripping piece is arranged to be forced
against the strap by a suitable mechanical device to grip the strap in contact with
it, substantially as described.
2. A buckle or fastening wherein a movable gripping piece is adapted to slide
between the bars of the frame and to be operated by means of a cam, substantially as
described by reference to Figures 1 to 7 of the drawing.
3. A buckle or fastening wherein the movable gripping piece is arranged over an
opening or recess in the frame and is carried upon and operated by a screw or a lever
substantially as described by reference to Figures 8 to 12 of the drawing.
4. The modified buckle or fastening wherein the frame has a protuberance and
the plate a corresponding recess between which the strap is clamped substantially as
described and illustrated in Figures 11 and 12 of the drawing.
5. The manufacture and use of buckles or fastenings substantially as hereinbefore
described and illustrated in the accompanying drawing.
