A communication from ANTON REICHE, of Dresden, Plauen, in the Empire of
Germany.
I, ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
M.I.M.E., do hereby declare the nature of this invention to be as follows:-
The object of this invention consists of a novelty in frames for placards and the
like.
Thin sheet metal is employed in the manufacture of these frames and is bent in a
tubular form with one edge beneath the other, the placard is then placed between the
two edges of the tube and by means of suitable punches pincers or equivalent means
is tightened sufficiently to prevent the same from being moved out of position. In
place of these tubular shaped frames semi-tubular frames can be used, but in this case
the metal sheet is bent in the shape of a horse shoe with one end longer than the other
and the margin or edge of the placard is placed between the two edges of the frame
whereafter the frame is pressed into a semi-circular shape by means of an appropriate
machine whereby the placard is securely fastened in the frame. These frames of
tubular or semi-tubular section distinguish themselves by their great rigidity against
bending or breaking and present the placard in a more advantageous manner than flat
frames as heretofore used.

Improvements in or relating to Frames for Placards, Advertisements
and the like.
A cominunication from ANTON REICHE, of Dresden, Plauen, in the Empire of
Germany.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., 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 frames or ribs for placards and the like, which are made
of metal and the resistance of which is increased by making them of circular or semi-
circular section.
In the accompanying drawing Fig. 1 is a perspective view of portion of a frame or
rib of circular section, Fig. 2 is a similar view of a rib of semi-circular section, Fig. 3
is a cross section of a circular, and Figs. 4 and 5 similar sections of a semi-
circular rib.
In the circular form shown in figs. 1 and 3 the metal sheet is bent or curved in
such a manner that the tube a¹ rests upon the straight portion a of the sheet while the
portion a' is spirally turned into tube a'. To connect a placard with this stiffening
band, frame or rib, the edge of said placard is inserted between portions a¹ and a²;
and to secure it in this position and prevent its lateral displacement a series of holes
are made by means of a suitable tool through portions a¹ and a² and the placard edge
between them whereby these parts are made firmly to adhere to each other.
This process enables the bands or ribs to be manufactured on a large scale in
factories, provided with machines for cutting metal sheets and rolling them up into

page_text: tubes, and then to be fitted together with the placards in the printing offices where
the latter are printed, and that without the employment of any machinery but simply
by hand, the holes being formed by means of a punch or other suitable hand operated
device. Such process offers this notable advantage over the well-known methods
which consist in applying the stiffening band or rib to the placard before its being
bent circularly, that the manufacture of the bands or ribs in question need not take
place on the same spot as that where the placards are prepared so that the same may
be put up for sale as a separate article of manufacture.
In the modifications illustrated by figs. 2, 4, and 5 the stiffening band or rib is so
formed that the semi-circular portion a' meets the straight portion a and that the
portion a similarly bent is embedded within the said portion a¹ (fig. 5) or surrounds
the same (fig. 4). The band or rib thus assumes practically the shape of a sickle.
In this case the placard edge may be most advantageously inserted between the
portions a¹ and a² before the metal is bent and then be secured in place by the act of
bending the metal so that no additional fastening is needed.
These bands or ribs also may be manufactured wholesale so as to be purchased as
they are required, by printing offices and other similar establishments. All that will
be necessary at the printing offices will be to provide at each such establishment a
bending machine as these bands or ribs can only be supplied in the shape shewn in
Figure 6 on a reduced scale and must be bent into the sickle shape by machinery
after the edge of the placard &c. is inserted into the blanks.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. Edge stiffening bands or ribs for placards and the like made of sheet metal
rolled up spirally the edge of the placard being inserted after the tube is finished
between portions such as a' and a² of the said band or rib and secured in position by
punching substantially as herein described and illustrated in figures 1 and 3 of the
accompanying drawings.
2. The method of fastening the edge of the placard between portions such as a
and a² of the band or rib rolled into a tube by boring or punching one or more holes
through portions a¹ a² of the tube and through the placard edge & held between them
substantially as herein described and illustrated in figures 1 and 3 of the accompanying
drawings.
3. Edge stiffening bands or ribs for placards and the like consisting of sheet metal
bent so as to assume practically the shape of a sickle in which the portion a² is bent
into or around the curved portion a¹ thereby holding the placard in place sub-
stantially as herein described and illustrated in figures 2, 4 and 5 of the accompanying
drawings.
