Im- PROVEMENTS IN SLIDE BUCKLES
Year: 1855

page_text: COMPLETE SPECIFICATION filed by Nehemiah Brough at the Office of
the Commissioners of Patents, with his Petition and Declaration, on
the 11th May 1855, pursuant to the 9th Section of the Patent Law
Amendment Act, 1852.
I, NEHEMIAH BROUGH, of Birmingham, in the County of Warwick,
Machinist, do hereby declare that the nature of my said Invention for "Im-
PROVEMENTS IN SLIDE BUCKLES," and the manner in which the same is to be
performed, are fully described and ascertained in and by the following state-
ment, reference being had to the Drawings hereunto annexed, and to the
letters and figures marked thereon, that is to say:-
My Invention consists of improvements in that description of slide or
buckle used for the purpose of adjusting and securing braces, belts, and other
similar articles of wearing apparel, by which they become self-acting, and are
more readily adapted to various lengths and girths, and that without any other
injury to the web or other material of which the said braces or girths may be
made, than would naturally arise from continual wear.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a front elevation of one of my slide buckles detached from the
brace.
2, a section of same. Figure 3, a back view of the buckle.
""
4, a view of the buckle attached to the brace.
"

"
5, a front elevation of another form of buckle, a modification of the
above.
6, a section; and Figure 7, a view of the same attached to the
brace.
8 and 9 shew an elevation and section of another form of buckle.
I will now proceed to describo the manufacture and mode of attaching the
buckle, seen in Figures 1, 2, 3, and 4. A thin face plate of metal (a) having
been stamped out to the form shewn in the Drawings, has the small lugs (b, b,)
turned round inwards, the lugs having holes sunk in them to receive pins
(c, c), formed on a second stamped plate of metal (d.) which is attached to
the pulleys or brace ends, or to the end of the girth or belt. The pins (c, c,)
are then sprang into the holes in the small lugs (b), and thus the two parts of
the buckle are connected. One edge of the under plate (d) is hollowed out,
as shewn at (e), to allow of the free passage of the web or other material of
which the brace or belt is made. Between this hollow and the face plate (a)
the web or other material is passed, which, when the brace or belt is in a
state of tension, is pinched between the angle (f) and the lower edge of the
face plate (a). To release it, it is simply necessary to slacken the web and
reduco the strain, when the buckle may be raised or lowered at pleasure; a
tensile strain restores it to a state of security.
The slide or buckle, shewn in Figures 5, 6, and 7, is a modification of the
above, made also in two parts, and consists of a face plate (a), having lugs
with holes pierced to receive small pins attached to the second or under plate,
which is made with a parallel bar running its entire length (b), one edge of
which is slightly sunk or chamfered in the press, and the web being passed
through, as seen in Figure 7. When the strain is upon the brace or belt, the
web is pinched between the edge of the face plate (a) and the corresponding
edge of the bar (b), and the greater the strain the greater is the pressure on
the web at this point, but when the strain is relaxed the slide will travel freely
up and down the web.
In the form of buckle shewn in Figures 8 and 9 it will be seen that a

page_text: slot (a) is cut through the under plate, into which slot the web is pressed
by the projecting flange (6) on the face plate, and thus the web is firmly
secured.
Having thus described the nature of my said Invention, and the manner in
which tho same is to be performed, I wish it to be clearly understood that
what I claim as of my Invention is, the improvements described in self-acting
slide buckles in any of the forms shewn, in manner herein fully set forth and
specified.
In witness whereof, I, the said Nehemiah Brougb, have hereunto set my
hand and seal, this Tenth day of May, in the year of our Lord One
thousand eight hundred and fifty-five.
NEHEMIAH (L.S.) BROUGH.
