IMPROVEMENTS IN THE MANUFACTURE OF BRASS HINGES
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
We JAMES HENRY STARLING of Rutland Place, Albany Road Harborne
Birmingham and JOHN WILLIAM BARNES of 2 Portland Place Camden Street,
Birmingham both in the County of Warwick, Brassfounders, do hereby declaro
the nature of the said invention for "IMPROVEMENTS IN THE MANUFACTURE OF
BRASS HINGES," to be as follows:-
-
This Invention relating to the manufacture of brass hinges has for its object the
production of the same in a more superior and economical manner than heretofore
In carrying out the Invention in order to effect this object, wo take two pieces
of brass and groove each of the same on one edge. We also take a rod of brass
either solid or tubular and cut the same up into sections of a suitable length. We
then place the two brass pieces one against the other, so that the grooves of the
two together form a channel or furrow in which we place the sections of the rod
and attach the same to the brass pieces by hard soldering or brazing, the alternato
sections being united to the opposite pieces of brass. When a solid rod is used for
the sections, the latter may be afterwards drilled, the hinge being in either case
completed by the insertion of a wire in the usual manner.
In lieu of grooving the brass pieces after they are cut or formed, wo inay produce
them with the grooves therein by casting, machine drawing or in any other
convenient manner, and the alternate sections of the rod may be separately
attached to their respective brass pieces.

Birmingham in the County of Warwick, Commercial Traveller and JOHN WILLIAM
BARNES of Portland Place, Camden Street, Birmingham aforesaid Accountant
Clerk do hereby declare the nature of said invention for "IMPROVEMENTS IN
THE MANUFACTURE OF BRASS HINGES," and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention relates to the manufacture of brass hinges, and has for its object
the production of the same, in a simpler and more efficient manner than heretoforc.
In carrying out our invention, we take two pieces of strip brass having concave
grooves on their inner edges; and within the seats of these grooves, we place short
lengths of tubing at intermediate distances-These short lengths of tubing are
brazed or hard soldered to the flaps or within the grooves; so that when the two
flaps to constitute a hinge are brought together, the knuckles of the one pass into
the gaps of the other, and when pinned together by a rod passing through the
knuckles, a perfect hinge is produced, which requires no dressing.
Instead of using sectional lengths of tubing for the knuckeles, short lengths of
wires may be used with like effect, which are subsequently drilled, the hinge in
each case being completed by the insertion of a wire in the usual way, through the
holes in the attached knuckle parts.
The lengths of strip metal to form the flaps, and having the grooved or concaved.
edges is produced by drawing, or by rolling, and the knuckle lengths of tubing or
rods are preferably cut from lengths of tubing or wire, although they may be
produced by turning up sheet metal.
The knuckle lengths of tubing are held to the flaps in the process of brazing or
soldering by clamps or otherwise prior to their introduction into a heated muffle.
We will now proceed to describe with reference to the accompanying Drawing
the manner in which our invention is to be performed.
Figure 1 is a plan of a butt hinge constructed according to our invention-
Figure 2 is an end elevation of the same, and figure 3 are parts of the hinge
separately Figure 4 is a cross section of figure 3-Figure 5 is a flap of one of the
sides of the hinge, before the attachment of the short lengths of tubing which
constitute the knuckle of the hinge-The said figure 5 is cut from the length of
drawn or rolled metal, figure 6, of which figure 7 is the section-Figure 8
represents short lengths of tubing cut from the length figure 9 which may be
opened, jointed or solid drawn, but preferably solid drawn-Figure 10 shows the
flaps of the hinge and the dotted lines represent the positions in which the
respective pieces of tubing are disposed with respect to the flaps-Figure 11 is a
cross section of figure 10-Figure 12 is a modification-In this case, the tube
constituting the knuckle of the hinge is only partially closed, the unclosed part has
fitted within it a longitudinal ridge or rib, standing from the concave seat of the
flap By connecting the flap to the knuckle as represented, a greater surface is
presented for the hard soldering of the parts together.
The same letters of reference indicate the same parts in the several figures of the
Drawing.

page_text: The butt hinge figure 1 consists of two flaps a a with concave seats a² a³ upon
the inner edge, as best seen in figures 7 and 11--These strips are preferably drawn
or rolled from sheet metal to the exact section required; and within the
concaves a² a² of each flap, short lengths of tubing bb lie and are therein hard
soldered; thus the short lengths of tubing or hollow cylinders bb figure 8, are
placed in the positions figures 3 and 10; that is, two are placed on one side of the
Hap, and three are placed on the other side of the flap, so as to leave intervening
spaces or gaps respectively equal to the length of one of the short lengths of
tubing b; and when so placed as already described they are brazed or bard soldered
to the flaps a a, as represented in figures 1 and 3.
By making the flaps and knuckles separately and afterwards connecting them
together by hard soldering, the manufacture or production of hinges are much
simplified.
The half hinges are put together by the insertion of a wire through the holes in
the alternate knuckles of each flap in the usual way, thereby connecting the two
half knuckles together, of which the pin is the joint or fulcrum.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed we declare that what
we claim is
The improvements in the manufacture of brass binges bereinbefore described and
illustrated in the several figures of the Drawing; that is to say, making the flaps
and knuckles of hinges separate from each other, and attaching them together by
hard soldering or brazing, the flaps being cut from strips of drawn or rolled metal
with one edge grooved or concaved, the knuckles being made from short lengths of
tubing or rods, the manufacture being carried out in the manner and for the
purpose as described; also the modification represented in figure 12.
