PROVISIONAL SPECIFICATION.
Improvements in Metallic Travelling Trunks and Boxes.
I GEORGE HENRY WILLIAMSON trading as Williamson and Sons of Providence
Works in the City of Worcester, Manufacturer do hereby declare the nature of
this invention to be as follows:-
My invention has reference to such metallic travelling trunks and boxes as have
wood bound lids bottoms sides and ends; that is, lids bottoms sides and ends having
parallel partly exposed wood bands fitted into them for protecting the said lids
bottoms sides and ends.
I will describe my invention as applied to the lids and bottoms of trunks and
boxes.
In the ordinary method of fitting wood bands to the lids and bottoms of metallic
travelling trunks and boxes, parallel recesses or "swages," with plain parallel sides,
are formed in the metallic lid or bottom and flat wood bands are dropped into the
said recesses or "swages" and secured in their places by metal crossing clips.
This, the ordinary, method necessitates the fitting of the wood bands in their
places prior to the japanning and stoving operations by which the metal trunk or
box is finished; there is also a tendency in the wood bands so fitted to warp.
My invention consists in fitting wood bands to the lids and bottoms of metallic
travelling trunks and boxes by the dovetailed arrangement hereinafter described,
whereby the wood bands can be fitted in their places after the trunk or box has
been japanned and stoved and the warping of the said bands when fitted in their
places is wholly or in great part prevented.
In carrying my invention into effect I form in the metallic lid and bottom of the
trunk or box a series of parallel dovetail grooves recesses or seats, the base or broader
end of the dovetail groove or seat being preferably of less breadth than the wood band
I fit in each of the said
or bar to be exposed on the outer face of the lid or bottom.
grooves, recesses or seats a dovetail wood bar or band of the following kind, I take
a wood bar of the breadth which it is desired the exposed part of the bar or band
proper shall have and I make on the sides of the said bar through its whole length
a dovetail of a size and shape proper to fit tightly in the dovetail groove or seat in
the lid or bottom of the trunk or box, leaving above the dovetail a broad crosshead
or piece constituting the exposed or acting part of the band. The wood band thus
made is fixed to the lid or bottom by driving its dovetail by an end motion into the
dovetail groove or seat, the broad crosshead or piece above the dovetail fitting flat
upon the outside of the lid or bottom and forming the exposed protecting wood
band of the lid or bottom. In this way the several dovetail grooves, recesses or
seats are fitted with wood bands. No fastenings or clips are required to secure
the dovetailed bars in their places and the shape of the dovetail grooves or seats
prevents the warping of the wood bars or bands through their whole length. The
wood bands thus fitted may however be prevented from moving endwise by
end clips.
"
Although I prefer to make the wood bands broader at top thau at bottom yet the
top or exposed part of the wood band may be made of the same breadth as
the base.
I fit the wood bands to the sides and ends of the trunk or box in the manner
before described with respect to the lids and bottoms.

1 GEORGE HENRY WILLIAMSON, trading as Williamson and Sons of Providence
Works in the City of Worcester, Manufacturer do hereby declare the nature of
my invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
My invention has reference to such metallic travelling trunks and boxes as have
wood bound lids, bottoms, sides and ends, that is, lids, bottoms sides and ends having
parallel partly exposed wood bands fitted into them for protecting the said lids,
bottoms sides and ends.
I will describe my invention as applied to the lids and bottoms of trunks and
boxes.
In the ordinary method of fitting wood bands to the lids and bottoms of metallic
travelling trunks and boxes, parallel recesses or
"swages "with plain parallel
sides are formed in the metallic lid or bottom and flat wood bands are dropped into
the said recesses or
swages" and secured in their places by metal crossing clips.
This, the ordinary, method necessitates the fitting of the wood bands in their places
prior to the japanning and stoving operations by which the metal trunk or box is
finished; there is also a tendency in the wood bands so fitted to warp.
My invention consists in fitting wood bands to the lids and bottoms of metallic
travelling trunks and boxes by the dovetailed arrangement hereinafter described
whereby the wood bands can be fitted in their places after the trunk or box has
been japanned and stoved and the warping of the said bands when fitted in their
places is wholly or in great part prevented.
In carrying my invention into effect I form in the metallic lid and bottom of the
trunk or box, a series of parallel dovetail grooves, recesses or seats, the base or
broader end of the dovetail groove or seat being preferably of less breadth than
the part of the wood band or bar to be exposed on the outer face of the lid or
bottom. I fit in each of the said grooves, recesses or seats, a dovetail wood bar or
band of the following kind. I take a wood bar of the breadth which it is desired
the exposed part of the bar or band proper shall have and I make on the sides of
the said bar, through its whole length, a dovetail of a size and shape proper to fit
tightly in the dovetail groove or seat in the lid or bottom of the trunk or box,
leaving above the dovetail, a broad crosshead or piece constituting the exposed or
acting part of the band. The wood band thus made is fixed to the lid or bottom
by driving its dovetail by an end motion into the dovetail groove or seat the broad
crosshead or piece above the dovetail fitting flat upon the outside of the lid or
bottom and forming the exposed protecting wood band of the lid or bottom.
In this way the several dovetail grooves, recesses or seats are fitted with wood
bands. No fastenings or clips need be used for securing the dovetailed bars in their
places and the shape of the dovetail grooves or seats prevents the warping of the
wood bars or bands through their whole length. The wood bands thus fitted may
however be prevented from moving end wise by end clips. I fit the wood bands to
the sides and ends of the trunk or box in the manner before described with respect
to the lids and bottoms.
Figure 1 of the accompanying drawing represents in perspective a metallic
travelling trunk or box, the lid, bottom, sides and ends of which are fitted with
wood bands according to my invention; Figure 2 represents a cross section and
Figure 3 a horizontal section of the same;
Figure 4 represents the corner or junction of the side and end wood bands and
parts adjacent thereto, drawn to a larger scale and Figure 5 represents a cross
section of the said Figure 4;

page_text: Figure 6 represents in side and end elevation one of the wood bands detached
drawn to the same scale as Figures 4 and 5.
The same letters of reference indicate the same parts in the several figures of the
drawing.
In the
a is the body of the metallic travelling trunk and 6 the lid of the same.
lid and in the bottom, sides and ends of the said body, dovetail grooves or seats
marked c are made, the said grooves or seats extending from end to end of the
parts in which they are made and being open at their ends. In the travelling trunk
represented, two parallel grooves or seats c, c are made in the lid and two in the
bottom and a single groove or seat in each of the sides and ends, the side and end
grooves being in the same plane or opposite one another as seen in the horizontal
section Figure 3; but I do not limit myself thereto as other number of grooves or
seats according to the size of the trunk may be used. In each of the dovetail grooves c
a wood bar or band marked d, d is fitted. It will be seen that about half of the depth
of the wood bar marked d constitutes the exposed or projecting part on the face of the
trunk and that the other part of the bar marked d' is formed into a dovetail through
its whole length, the said dovetail having a size and shape proper to fit tightly in the
dovetail groove or seat in the trunk. The said wood bars or bands d, d' are fixed in the
dovetail grooves c by driving their dovetails d' by an end motion into the said dovetail
grooves, the broad head or part d being situated outside the groove, and I prefer to
prevent the wood bars or bands from moving end wise in their grooves or seats by
means of end metallic clips as represented in the drawing. The wood bars or bands
of the lid and bottom of the trunk are fixed by the end angle clips e, e fastened in
their places by the screw pins and nuts represented, and the wood bars or bands
of the sides and ends are fastened in their places by the angle clips f, f and the
screw pins and nuts as best seen in the enlarged views Figures 4 and 5.
Although I prefer to make the wood bars or bands broader at top than at bottom
as represented, yet the top or exposed protecting part of the wood bar or band may
be made of the same breadth as the dovetail base part.
By the dovetailed arrangement herein before described and illustrated, the wood
bars or bands can be fitted in their places in the sides, top bottom and ends of the
trunk or box or in some of the said parts, after the trunk or box has been japanned
and stoved, and the warping of the said bars or bands fitted in their places is wholly
or in part prevented.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that I claim
as my invention ;-
The improvements in metallic travelling trunks and boxes having wood bound
lids, bottoms, sides and ends, or having one or more of the said parts wood bound
herein before described and illustrated in the accompanying drawing; that is to
say, fitting wood bars or bands to the exterior of the metallic trunks or boxes by
the dovetailed arrangement described aud illustrated, whereby the said wood bars
or bands can be fitted in their places after the trunk or box has been japanned and
stoved and the warping of the fitted bars or bands wholly or mainly prevented
substantially as described and illustrated.
Dated the Thirteenth day of August 1894.
