The forming apparatus herein is horizontally
elongated and highly flexible. This apparatus is
constructed in various lengths and widths depending
on the users requirements. Hereon vertical tabs are
welded to the outside of the form at pre-determined
intervals to support angled iron to achieve horizontally
straight and sturdy forming. Whereby removing said
angled iron, you are able to achieve any desired
curve, whether concave or convex. A manually adjust-
able apparatus, consisting of two sections of tube
steel, one having a larger inside diameter than the
outside diameter of the other, wherein assembled are
slidable for horizontal adjusting of the said forms.
Hereon, welded to the said adjuster, a vertical round
tube having a set screw within, holds a vertical
steel rod. Herein the steel rod is driven into the
earth for stability and vertical adjusting is achieved
by means of the set screw. Hereon each length of form,
end plates are welded at ninety degree angles, whereby
two sections can be assembled by means of male and
female connection. By means of each section's ability
to connect, these forms can be assembled and dismantled
for transportation from job site to job site.

THE EMBODIMENTS OF THE INVENTION IN WHICH AN
EXCLUSIVE PROPERTY OR RIGHTS ARE CLAIMED ARE:
1. Slab forming apparatus for forming sections
of concrete slabs in a pre-determined area comprised
of elongated cold rolled steel of various lengths
and widths having pre-cut plates of cold rolled steel
welded at ninety degree angles to both ends of the
elongated cold rolled steel, wherein one end being
comprised of two pre-drilled holes and the opposite
end having two stud bolts welded to said steel plate,
wherein this procedure is carried out on several
sections of elongated cold rolled steel, can be
assembled precisely and effectively to form longer
sections which when placed upon the ground horizontally
can be arranged to hold concrete within its form to
achieve the desired shape and size of any given
slab of concrete.
2. The slab forming apparatus as stated in
claim 1 enhanced by a manually adjusting apparatus
fastened to the outside of the steel form by means
of welding, enables the said forms to be adjusted
in the horizontal and/or vertical directions.
3. The slab forming apparatus as stated in
claims 1 and 2 characterized by steel tabs cut in
an "L" shape when welded to the outside of the form
at pre-determined intervals act as a permanent guide
for inserting angled iron to achieve and maintain
horizontally straight sections of forming. Whereas
curved sections are required, the angled iron can
be removed or omitted.
4. The slab forming apparatus as set forth
in the able claims 1 through 3 when characterized
by prefabricated right angled sections (inside and
outside) allows the user(s) to achieve accurate and
efficient square or right angle corners.

Description

Thls in~ention relates to a manually opera~le
concrete ~orming apparatu~. Wood forming is commonlv
used throughout the concrete ~orming industry. Woo~
forms mu~t be cut to fit the ~ob at hand. To achieve
curve~, the ~ood i~ usually ~oakea in water to make
it pliable~ Wocd forms are a~sembled l?y mean~ oî
wlre nails. The li~espan o~ wood Iorms range ~rom
five to twelv~ uses. Skilled workers are al~o needed
~or the ~et up o~ ~uch ~orming and can be ~ery time
eonsuming.
I have found that the~e di~ad~Tantages can be
o~ercome by u~ing cold rolled ~teel cut in various
lengths and width~ and attach~ng thereon an apparatus
to allow :or hori20ntal and ~ertl~al movement, which
15 permi ts e~tremely :~ast ~lne tunlng in the i`ormlng
proce~s~ ~y means of male ana female connector~,
the~ form~ can be quickly as~emblea wlthout the use
o~ wire nall3. Curve~ can be a~hi~ed rela~ively
ea8i:1y without br~aking ~r warping; also the~e forms
.~ 20 can achie~e and maintain curves which cannot be done
wlth w~d. Where~n s~raight ~ ineY are required,
~:~ angled iron plaeed ~n tab~ ~slded to the out3ide of
the ~orm will produce exact and ~peedy formin~
Ri~h~ angle ~ction~ ar~ availab~ for fa~t forming,

or outside ri~ht angle~. A stake ~older i~ welded to
the hori20ntal and ~ertical ad~u~ter to allow for
