Improvements in Connecting Crossed Bars.
I, HEINRICH RINGEL, of Elberfeld, Ernststrasse No. 38, Rhenish Prussia,
Germany, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
My invention relates to a new manner of connecting or locking together bars,
which cross each other and which lie in the same plane, at their crossing-point
without welding or soldering them together or combining them by rivets screw
bolts and like means used hitherto. My new method of connecting crossed bars
besides giving a very convenient and cheap connection, at the same time serves for
decorating purposes in making iron gates and railings and fencing. The invention
consists in the main in the following: the crossing bars are each bent out to half
their thickness at the crossing point or each of them is notched to that extent at the
crossing point; they are then laid over each other and a box-like cover, having
notches cut into its rim corresponding with the position of the crossed bars, is
placed over them, say from the bottom side; a similar box is then put upon
the bars from the top side, so that its rim reaches into the inside of the first
box. The rim of the second box being about of same height as the thickness of
the bars; that of the first one being made so much higher, that when both boxes
are put upon the crossing bars and into each other the edges of the rim of the
larger one can be lapped over the bottom of the smaller box and thus the con-
nection is completed.
The bottoms of the boxes can be carried out in form of ornamented rosettes
with embossed work upon them, and they may be made of different metal for
ornamental purposes.
In place of making them circular the connecting boxes may be of cross shape
so that the bars will be surrounded by the arms of these cross boxes a certain
distance right and left beyond the crossing point.
On the accompanying drawing the new method of connecting crossing bars
is shown in the two manners mentioned above.
Figure 1 shows two crossed bars with one half of a connecting box put upon
them;
Figure 2 shows the same with both boxes put upon them in a finished state;
Figure 3 is a section along line I-I;
Fig. 4 is a sectional view along line II-II;
Figs. 5, 6 and 7 show the boxes in detail;
Fig. 8 shows two crossed bars with one half of a cross shaped box put upon
them;
Fig. 9 shows the same with both boxes put upon them in a finished state;
Figs. 12 and 13 show the blanks for making the cross shaped connecting boxes;
Figs. 14, 15 and 16 show these boxes in detail.
The bars A, B are bent out to half their thickness, as shown in Fig. 3, at those
places where they cross each other, or they are notched to half their thickness as
shown in Figure 10, then they are placed one over the other and a box C having
[Price 8d.1

page_text: notches D in its rim is stuck upon the two bars so that these are embedded in the
box and the notches in its rim; the other (half) box C¹ is then put over the bars
and the first box and the rim of the box C¹ is then flanged over the edge formed by
the bottom and the rim of the first box, as best seen from Figs. 2 and 4 and thus
the connection is completed.
In the example shown by Figs. 8-16 the two bars a, b, by preference, are notched
instead of being bent, as shown in Fig. 10 and placed over each other as in the first
case. In place of the circular boxes, C and C³, I use cross shaped boxes or
collars c and c Figs. 14, 15 and 16. These are made out of blanks of the forms
shown by Figs. 12 and 13. The width of the wings e, Fig. 13 for the small or interior
box being equal to the circumference of the bars; the width of the wings e¹ of the
blank Fig. 12 being of such length as to correspond to the circumference of the bar
surrounded by the cross box e.
These blanks are partly cut by the rectangular lines f and f and they are then
pressed into the shapes shown by Figs. 14-16, the wings e and e¹ forming half
circular channels e a and e b; e a and e¹ b. The smaller one, c, Fig. 16, is then put
upon the crossed bars as shown in Fig. 8 and the wings pressed round the bars, that
they meet at their edges in the centre line of the bars, the triangular corner
pieces being also pressed inwardly towards the corners of the bars, and then the
larger cross bar c¹ is put over the bars and the first cross box in the same way, as
shown by Figs. 9, 10 and 11, the wings covering and surrounding wholly the bars
and the first box and the corner pieces g' covering the corner pieces g, and thus the
whole is kept firmly together, giving a secure and nicely finished connection.
When made of polished brass and the bars varnished in black the whole has a
pleasing and decorative appearance.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1.) The new method of connecting bars crossing each other and lying for the
main part in the same plane, by either bending them out half their thickness or
notching them to half their thickness at the crossing points, then laying the bars
over each other cross ways and putting a box C, having notched rims, over them
from one side, placing a similar box C¹ over the bars and the first box from the
other side and flanging the rim of the larger box over the bottom edge of the
smaller box, the whole as described and illustrated and for the purpose set forth
(Fig. 1-7).
2.) A variation of carrying out the method of connecting crossing bars described
in claim one shown by Figs. 8-16 and consisting in this, that the bars are notched
to half their thickness, then placed over each other, a cross shaped box c being
then stuck upon the two bars from one side and pressing the wings e round the
bars and the triangular corner pieces into the corners of the crossing bars,
putting then the larger box c¹ over the bars and the first box, so that the wings e
surround the bars and the wings e and that the corner pieces g¹ cover the corner
pieces g, the whole as described and illustrated and for the purpose set forth
(Fig. 8-16).
