This invention relates to the construction of wooden
panels, and more particularly relates to an improved
method and an improved apparatus for constructing
wooden panels to be used in the assembling‘ of complete
buildings or other structures.
' In the construction of prep-fabricated wooden panels or
trusses for use in assembling complete buildings or other
structures, it has been found that one of the simplest
methods of forming these panels is to lay out the timber
to be used in the desired pattern, place fasteners such as
Referring now to the several ?gures, the apparatus
comprises a press generally indicated at 1 having a rein
forced concrete head 2 and a reinforced concrete base
4. The head is formed with a cavity 6 which can be
?lled with sand or water to increase its weigh’t- ThlS
sand or water can be removed from the head by means
of a drain 8.
The base of the press is provided with a number of
pipes 10, preferably one at each corner, which are an
chored to the reinforcing, and which cooperate with a
like number of pipe sleeves 12 cast in the head‘2 and
anchored to the reinforcing therein to guide the head as
it is lifted and lowered with respect to the base. The
head is lifted from the base by means of a number of
hydraulic jacks 14, located at each end of the press.

results.
According to the present invention, it is proposed that
panels be formed by using a simple and inexpensive press
to drive fasteners into timber members that have pre
viously been laid out in the desired pattern.
It is therefore among the objects of the present inven
tion to provide a method for cheaply and quickly form
ing wooden panels for use in the construction of buildings
and other structures.
It is another object of the invention to provide an ap
paratus for use in constructing wooden panels.
It is a further object of the invention to provide a
press which can be used in the construction of wooden 55
panels.
It is a still further object to provide a press that can

These handles may be engaged by the books of a pair of
granes and the head slid up the pipes and away from the
ass.
The apparatus is provided with a pair of tables 22 and
24 mounted by means of hinges to the base of the press
so that they can be folded out of the way when the press
is not in operation. Each of the tables is provided with
a plurality of roller conveyers 26 and a number of binge
ably mounted supporting legs 28. A jig 30 is provided
for each table, and is freely movable thereon due to the
roller conveyers 26. It is to be understood that only one
such table 24 need be provided, and it need not be hinged,
although the preferred embodiment would use two hinged
tables as shown.
In order to facilitate the free rolling of the jig, the base
of the press is provided with a plurality of spring-loaded
expensive press which utilizes the force of gravity for its 60 ball casters 32 cast in the concrete. The jig can thus be
