Improvements in or relating to Advertising Devices.
A communication from GEORGE FRANCIS BURTON, of Toronto, County of York,
Province of Ontario, Canada, Barrister-at-Law.
I, ALFRED JULIUS BOULT, of 323, High Holborn, in the County of Middlesex,
Chartered Patent Agent, 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 :-
The object of the invention is to provide a simple device by which advertising
cards and similar devices may be readily held in a conspicuous position and as
easily removed and it consists essentially, of a frame for holding the advertising
device and having a groove or projection or clips formed on or connected to one
edge and arranged to engage with a projection, groove or rod, formed on or
connected to the surface on which the frame is placed, in combination with a spring
latch arranged to lock the frame into its holding device, the whole being constructed
substantially as hereinafter more particularly explained.
Figure 1 is a perspective inside view showing the device applied to the roof of a
street car.
Figure 2 is an enlarged detail of the frame with a portion of the moulding in
section.
Figure 3 is a sectional detail of the latch.
Figure 4 is a detail of the key for unlocking the latch.
Figures 5 and 6 are alternative forms of moulding for holding the frame in
position.
Figure 7 is an inside view of the frame arranged in connection with detachable
supporting rods.
Figure 8 is an enlarged view of the adjustable end of one of the supporting
rods.
Figure 9 is a detail of one of the clips fixed to the end of the frame opposite to
the spring.
On the surface of the frame A, is printed or otherwise placed the advertising
matter. On one edge of the frame A, is formed a groove a, as shown in Figure 2,
a projection b, as shown in Figure 5, a clip d, as shown in Figure 6, or forks, f, as
shown in Figure 7.
B, is a moulding connected to the surface on which it is designed that the
advertisement should be displayed. On this moulding B, is formed a beading C,
when it is designed to engage with the groove a, or the clip d; or when the
projection is used on the frame A, there is formed a groove e in the moulding B.
This holds one end of the frame A; the other end fits against a moulding D, and
in order to lock the frame in position, a spring latch E is provided, either fixed
to the frame A, as shown in Figure 2, or connected to the moulding D. In the
former case, the latch will engage with a groove made in the moulding D, as
indicated in Figure 2, or if the latch is connected to the moulding, it will engage
with a groove made in the frame A.
In order to put the frame in position, the grooved end or its equivalent is placed
on the moulding B, and the other end of the frame pushed in behind the moulding D,
the spring latch E, springing past the moulding and locking the frame in position.
My correspondent does not claim anything peculiar in the spring latch or in the
key F, but they are shown in the drawing as illustrating the practical way of
accomplishing his purpose.

page_text: In order to prevent the frame A rattling steel springs or pieces of rubber or
other material are placed in such a position as to hold it steady.
When it is desired to place the frame in position without the use of permanent
mouldings, a rod G is placed at the top and bottom of the space to be occupied by
the frame, one end of each rod G having a spike g or piece of rubber / connected
to its end so that the said end may be fixed in position by forcing the spike g or
piece of rubber h into or against a rib or the end of the car. In some cases both
the rubber and the spike are used, but except in the case of heavy advertising
cards, either one or the other alone will be sufficient. The opposite end of each
rod G, has a screw cut upon it on which the nut H is screwed behind the end I
which is likewise screwed upon the end of the rod.
A spike I
and a piece of rubber h are likewise placed on the end I to correspond
with and serve the same purpose as the spike and rubber on the opposite end of
the rod.
When the rod G is placed in position, the end I is adjusted so as to force the
spikes into the ribs or the end of the car thereby locking the rod in position.
The nut H is then screwed against the end I so as to serve as a lock nut and
prevent the unscrewing of the end I.
The spring latch E used with the rods G is adapted to operate without the use
of a key and consists of a flat spring plate, each end being forked as indicated to
fit over the rod G. The lower edge of the frame may be adapted to engage with
the lower rod G, by any of the devices already described. The rods G are
arranged the proper distance apart to receive the frame A.
In order to place the frame in position, it is held so that the forked ends of the
latch shall fit over the rod G. Pressure is then applied so as to compress the
spring latch and permit the lower edge of the frame to engage with the lower
rod G.
From this description it will be seen that the advertising frame may be put in
position when desired without the use of any permanent mouldings although it is
preferred to use the frames A, plain boards might be substituted. When the
frames are used it is preferred that each frame should be provided with a back J,
held in position at one end by the spikes i, and at its other end by a button j, so
that the advertisement in the frame can be readily and quickly changed.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated by
my foreign correspondent, I declare that what I claim is :-
1. A. frame for holding an advertising device having a groove or projection
formed on or connected to one edge and arranged to engage with a projection or
groove formed on or connected to the surface on which the frame is placed, in
combination with a spring latch arranged to lock the frame into its holding device
the whole being arranged substantially as and for the purpose specified.
2. Two parallel rods held the proper distance apart to receive a frame in
combination with a spring plate connected to the frame and arranged by its elastic
pressure to hold the frame in connection with the rods substantially as and for the
purpose specified.
3. The frame A having the forked end spring plate E connected at one end and
the fork-shaped clips at its other end in combination with the rods G arranged
substantially as and for the purpose specified.
4. The frame A having the forked end spring plate E connected at one end and
the fork-shaped clips at its other end in combination with the rods G each rod
having an adjustable end I and a holdfast such as the spike g substantially as and
for the purpose specified.
5. A frame for holding the advertising device and having a groove or projection
formed on or connected to one edge and arranged to engage with a projection or
groove formed on or connected to the surface on which the frame is placed in

page_text: combination with a spring latch arranged to lock the frame into its holding device
and a spring bearing on said frame and surface whereby the frame is kept from
rattling the whole being arranged substantially as and for the purpose specified.
Dated this 8th day of June 1893.

Of London, Nottingham, Liverpool, and Manchester.
