PROVISIONAL SPECIFICATION.
Improvements in Means for Jointing Wood and similar Material.
I FREDERICK WILLIAM GOLBY of 36 Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention as com-
municated to me by Oswald Heinrich of Mittelwalde, Germany, Merchant,
Michael Goldschmidt, Siegfried Goldschmidt and Philipp 'Goldschmidt, all of
Breslau, Germany, Manufacturers, to be as follows:-
This invention relates to improvements in jointing boards bars, or other articles
of wood or other similar material, as for instance the sides, bottom and cover of a
case or box, and the joint may either be made permanent, when applied to the sides
and bottom of a case or box, or it may be made sliding or detachable, as applied to
the top or cover of the case.
The new means of jointing two boards, bars, or articles of wood consist of pieces
or lengths of sheet metal bent to form an angle of the shape of an angle iron. The
lengths of angular sheet metal are driven into the wood of the two boards, bars
objects to be jointed, and when the wood is too hard to drive the sheet metal int
it, cuts may be prepared to receive the sides of the angle piece.
The said angular lengths or pieces of sheet metal may be provided at the upper
or lower end, or at both ends, or at one or both sides with a flap or flaps, or flanges
projecting from the wood after the angle piece has been driven in, said flap or flaps,
or flanges, are bent down to the surface of the wood, when the joint has been made,
and thereby the joint obtains a superior hold and solidity. The said flaps or flanges
be provided with indentations, to catch into the wood, when bent down. When
the joint is desired to be detachable, as with the top or cover of a case or box, the
said angle piece of sheet metal, instead of being driven into the wood or material
of the two boards to be jointed, is laid in a groove or channel prepared in the said
boards or bars or pieces of wood and the top or cover of the case has a sliding
motion on the said angle piece.
may
The new jointing means may be constructed in various ways. They may be
tapered and sharpened, so as to better adapt them to be driven into the wood. Or
they may be provided with slots into which the fibres of the cut wood may enter.
Or the sheet metal forming the jointing means is provided with a recess of any
shape, and the flaps produced by the recess are bent to the right and to the left, so
as to lie spring like in the wood or pressing against the faces of the latter.
In some cases it is preferable to make the sheet metal undulatory and to provide
it with a taper and slots. The side flanges may also have indentations, as well as
slots. Or the jointing means may be constructed with teeth or projections of a
different form and provided with sharpened edges.
The new jointing means of this invention may with great advantage be employed
for jointing the panels of inlaid floors; the panels, jointed to each other by the
angular strips of sheet metal, are prevented from becoming awry, as is frequently
the case with other methods of jointing the panels.
It will be evident, that the mode of employing the new jointing is not limited to
the special purposes of use above indicated, but that the jointing may be applied to
a variety of objects and to all kinds of material, which like wood, allow of the
angle pieces being inserted.

I FREDERICK WILLIAM GOLBY of 36 Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention as com-
municated to me by Oswald Heinrich of Mittelwalde, Germany, Merchant,
Michael Goldschmidt, Siegfried Goldschmidt and Philipp Goldschmidt, all of
Breslau, Germany, Manufacturers, 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 improvements in jointing boards, bars or other articles
of wood or other similar material, as for instance the sides, bottom and cover of a
case or box and the joint may either be made so as permit a firm and durable
connection or it may be made in such a manner that it may be withdrawn from the
wood, as the case may be.
The accompanying drawings illustrate the invention.
Figures 1 and 2 represent a jointing piece made according to this invention.
This joint consists of a piece of sheet-metal d which is provided at the lower end
with one or two flanges c and as shewn in Figure 2, it may also be provided with
an angular flange e;
Figure 3 shews the application of this jointing piece.
When the piece d is driven into the walls a. b which are to be joined together,
so that the flange e prevents the walls to be joined from being drawn upwards and
when the flanges c care bent around, then the jointing piece is held in the wall'b.
But a good connection of the walls ab is only attained after having bent the upper
flange c'. By bending back again the said flange c' the wall a is disconnected from
the wall b.
Figures 4 and 5 represent an angle piece for joining two longitudinal pieces of
wood a b. Also in this modification the piece d is driven into the wood in such a
manner that it projects beyond the wood, so as to be bent around at e, Figure 4.
It is obvious that the said jointing pieces can only be driven into soft material,
in using hard material it is preferable to first make cuts or recesses into the material
to be joined together.
In Figures 6 and 7 is shewn another modification which is particularly intended
to be used in the manufacture of cases and the like. The two transverse pieces of
wood a¹ are connected to the longitudinal piece m by means of the angle pieces d'
which are driven into the wood and then bent around at e. The longitudinal piece
of wood m is connected to the bottom of the case by means of angle-pieces d'; these
pieces being bent at e at the sides and at the lower end.
A further modification is shewn in Figures 8 and 9, in which the jointing-piece d³
is provided with an upper and a lower flange e and with a side flange e' which bears
against the pieces to be joined together. Instead of the piece d³ a piece d' may
also be used which is provided with a lower flange e a lateral flange e¹ and an upper
flange e. The latter flange e is preferably toothed, so as to be able to drive it
better into the wood.
•
The joining piece d represented in Figure 10 is provided with lateral flanges f,
while it is pointed at fat the lower end, so that it may be better driven into the
wood. This piece d is also provided with a flange e and a slot f* into which the
wood-fibres may enter.
The piece d shewn in Figure 11 is similar to that represented in Figure 10. It
differs only in that it has no slot but a T shaped recess, the flaps of which are
bent to the left and to the right, so as to act within the wood as a spring.

page_text: The recesses may also have any other suitable form as shewn in Figure 12 where
several recesses are arranged. In the modification shewn in Figure 13 the side
flanges are toothed and slots f" serve to receive the wood fibres.
In Figure 14 is shewn a modification, in which the piece d is provided with ribs f³
and with a sharpened edge f¹. The ribs may be of any suitable cross-section.
Also in this modification a flange e is used which permits the partial withdrawing
of the joining piece.
The joining-means shown in Figures 15, 16 and 17 consist of sheet-metal pieces d,
the longitudinal edges of which are spirally wound, so that they are gradually
driven into the wood without turning themselves. The lower end of these pieces is
pointed.
The modification shewn in Figure 18 is provided with but one spiral edge g,
while at the other side it is provided with a flange and at the upper end with a
flange e which permit the withdrawing of the joining-piece.
The modification shewn in Figure 19 is sharpened at while the modification
represented in Figure 20 is provided with a toothed edge g and a toothed
flange f
In Figures 21 and 22 are shewn joining means having two spiral edges gg. The
lower part is sharpened at fl and the upper end is provided with flanges e
permitting the withdrawing of the joining piece.
Figure 23 shews a joining piece consisting of one piece of spirally wound sheet
metal g.
It will be evident that the mode of employing the new jointing is not limited to
the special purposes of use above indicated, but that the jointing may be applied
to a variety of objects and to all kinds of material which like wood allow of the
jointing means being inserted.
Having now particularly described and ascertained the nature of this said inven-
Lion and in what manner the same is to be performed I declare that what I
claim is :-
1. Means for jointing wood and similar material consisting of sheet-metal pieces
provided with lateral and upper-flanges which allow of partially withdrawing the
jointing means, as and for the purpose set forth.
2. Means for jointing wood and similar material, said means having spirally
wound longitudinal edges, whereby they may be gradually driven into the wood,
without turning, while upper flanges may be provided for as and for the purpose
set forth.
