Timber or Frames for Boats, Vessels, or other Structures.
I, OLIVER IMRAY, of No. 28 Southampton Buildings, Chancery Lane in the
County of Middlesex, Fellow of the Institute of Patent Agents, do hereby declare the
nature of this invention to be as follows:-
This invention relates to an apparatus or implement for bending, shaping or setting
curved frames of timber or metal such as are used in framing and constructing boats
or vessels, for articles of furniture, for arched jambs and other structures. For this
purpose a platform is provided, which may consist of a number of parallel planks when
it is to be used for bending wood, or which may be of iron or of wood faced with iron
when it is to be used for bending heated metal bars. In this platform there are a
number of bolt holes into any of which can be inserted the hooked ends of screw
swivels. Near one edge of the platform about the middle of its length there are slotted
holes in any part of each of which can be fixed by a nut an upright bolt. Two strips
of steel or other flexible bar are provided, each strip terminating in an eye which
embraces one of the upright bolts. The required curves being drawn on the platform,
as, for instance, those for the rib of a boat, the two bolts are set at a distance apart
corresponding to the width of the keel, and the flexible bars are bent to the curves and
held firmly by a number of screw swivels, each of which has its one end hooked into
one of the holes of the platform, and its other end attached to one of the flexible bars.
By screwing or unscrewing those swivels, the various parts of the bars
can be accurately adjusted to the desired curves. The timber to be bent, softened by
steaming, is laid along the bent bar, and clamped to it by a number of clamps, which
are left on until the timber becomes set to shape. In like manner, when metal bars
have to be bent they are clamped to the flexible bars. When the metal to be bent is
heated, the flexible bars should be protected from being injured by the heat, by inter-
posing packing pieces between thein and the heated metal.

An Apparatus or Implement for Bending, Shaping, or Setting Ourved
Timber or Frames for Boats, Vessels, or other Structures.
I, OLIVER IMRAY, of No. 28 Southampton Buildings Chancery Lane, in the County
of Middlesex, Fellow of the Institute of Patent 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
This invention relates to an apparatus or implement for bending, shaping or setting
curved frames of timber or metal such as are used in framing and constructing boats
or vessels, for articles of furniture, for arched jambs and other structures. For this
purpose, a platform is provided, which may consist of a number of parallel planks when
it is to be used for bending wood, or which may be of iron or of wood faced with iron
when it is to be used for bending heated metal bars. In this platform there are a
number of bolt holes into any of which can be inserted the hooked ends of screw
swivels. Near one edge of the platform about the middle of its length there are slotted
holes in any part of each of which can be fixed by a nut an upright bolt. Two strips
of steel or other flexible bar are provided, each strip terminating in an eye which
embraces one of the upright bolts. The required curves being drawn on the platform
as, for instance, those for the rib of a boat, the two bolts are set at a distance apart cor-
responding to the width of the keel, and the flexible bars are bent to the curves and
held firmly by a number of screw swivels, each of which has its one end hooked into
one of the holes of the platform, and its other end attached to one of the flexible bars.
By screwing or unscrewing those swivels, the various parts of the bars can be accu-
rately adjusted to the desired curves. The timber to be bent, softened by steaming, is
laid along the bent bar, and clamped to it by a number of clamps, which are left on
until the timber becomes set to shape. In like manner, when metal bars have to be
hent they are clamped to the flexible bars. When the metal to be bent is heated, the
flexible bars should be protected from being injured by the heat, by interposing packing
pieces between them and the heated metal."
Fig. 1 of the accompanying drawings is a plan, Fig. 2 a transverse section and
Fig. 3 a front view of apparatus according to this invention. A is the platform which
may be of metal or wood faced with metal; pierced with numerous holes in any of
which as at B are fixed bolts to take the eyes of scrow swivels C. These swivels at
their other ends take hold of steel strips D which, by means of the screw adjustment
of the numerous swivels employed, can be set to the shape to which it is desired to
bend a rib or timber. The eyes E at the ends of the strips D engage on studs e pro-
jecting up from a crosshead F through slots of a fixed plate J. The crosshead F can
be adjusted a little backwards or forwards by a screw G, and when it is drawn
fully back the studs e may be set closer together and clamped in position by hand
nuts H. It is convenient to make the platform A as shewn of separate planks with
spaces between them which allow of the introduction of clamps to hold the bent pieces

page_text: to the strips D and to the platform. When the apparatus is to be used for bending
hoated iron, it should be made of or faced with iron plates, and the strips D should
have numerous studs projecting from their outer surfaces to keep the heated metal
from actual contact with the strips.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
The construction and use of an apparatus or implement for bending, shaping or
setting curved timbers or the like, substantially as herein described and illustrated by
the drawings.
