This practice has several disadvantages among
exposed metal surfaces.
More particularly this invention is adapted to
be used in the process of applying coverings of
cementitious material to the exposed surfaces of
metal structures whether for the purpose of insulating, waterproo?ng or ?reproo?ng, or for the

In the art of structural steelwork, although
not necessarily limited thereto, it has become a
more or less regular practice to plaster the exposed portions of the completed metal structure

protecting them from the ‘elements.
As known to those well versed in the art, this
is commonly done by a methodknown. as the

One of the chief difficulties encountered in this
45. type of work has been in connection with the
erection of the shooting strips. Ordinarily the
only available surface to which they may be attached is the very surface which is to be coated.
Since it is impossible to nail the strips to the
50 metal work the common practice has been to
weld the head of an ordinary nail to the metal
surface with the body portion of the nail substantially normal to the surface. A series of
these nails were so disposed at convenient points

having the desired physical properties.
The ends of the clip H are irregularly shaped,
which shaping may be done in a single cutting
operation or the shaping may be done in subse
quent operations.
The lower, or tail end of, the clip is formed
with a notch i2, the vertex of which is on the
longitudinal center line, thus giving the end‘ a

As shown in the drawing,
the notch I2 is a right angle, which is most de

of the clip shoulders may be used to sight the
imaginary ?nish line. By applying the cemen
titious material on both surfaces until the sides
of the clip are covered, a bevel edge is formed on
the corner of the ?nished structure. This bev- _
eled edge is as wide as the width of the clip.

of' the coated surface.
The spikes may be left
flush with the'beveled surface.
The notching operation results in the forma
tion of two projecting points l3 and M which
may be bent in either direction along their‘
broadest surface to form feet upon which the
20 clip may rest in an upright position as shown‘
‘in Fig. 5, or which will give a broad contacting
area when held against any: surface.
Since the clip is designed primarily to be sus
pended from metal objects or surfaces, the feet

easily secured. to the metal surface by welding.
In actual usage this operation may be speedily
performed. The workman merely grasps the
clip, bends the points l3 and I4 over in either
30 the same or opposite directions with a pair of
pliers, holds the clip in position against the metal '
structure and welds the feet, formed by bend
ing the points over, to the metal surface as illus
trated in Fig. 5. A series of these clips may be

Where the cementitious coating is to be applied
to an irregular’ surface, such as the corner of a
55 beam or ?ange, it is sometimes desirable tosup
port the shooting strip at an angle to both sur
faces, as is shown in Fig. 4. To do this, the clip
is placed on the corner of the structure or work

intersection of the sides of the notch 12' and
the surfaces of the workpiece.
The central portion of the upper end of the
clip is extended to form a spike I8, the tip of

To either
side of the point I‘! are formed shoulders 20
and 2|.
In placing the shooting strip 22in position, it
is driven on to the spiked portion l1 until the
70 strip contacts the shoulders 26 and 2|. The
shoulders act as a stop or guide to maintain the
distance between the workpiece l6 and the

and it is desired therefore that only such limita
10 tions shall be placed thereon as are imposed by
the prior art or are speci?cally set forth in the
appended claims.
I claim:
1. A form clip adapted to be welded to metal
structure members for the support of forms or
guides in spaced relation thereto comprising a
?at body of weldable material having one end
extended longitudinally to form a spike adapted
for limited penetration into the form or guide,
and the opposite end cut irregularly to provide
extended portions bendable transversely of the
plane of said body to form feet adapted for en
gagement with the surface of the structure mem
ber for the purpose of welding thereto, the sides
of said extended portions being formed to en
gage in abutting relation the adjacent surfaces
at the corners of said structure members.
2. A form clip adapted to be welded to metal
structure members for the support of forms or
guides in spaced relation thereto, comprising a
main body portion of substantially thin weldable
material having one end adapted for limited
penetration into said form for rigid engagement
therewith, and the opposite end notched to form
a pair of extending members, the sides of said
notch being adapted for abutting engagement
with the sides adjacent the edges of said struc
ture members, said extending members being
readily bendable transversely of said main body
portion to form a substantially broad base which
when placed in abutting relation to a surface of
said metal structure member provides an exten
sive contacting area for the purpose of welding.
3. A form clip adapted to be welded to metal
structure members for the support of forms or
guides in spaced relation thereto comprising a
flat sheet metal body having part of one end ex
tended longitudinally to form a ?at-endspike,
3 .
transversely relative to the longitudinal axis of 10
said spike.
4. A form clip adapted to be welded to metal
structure members for the support of forms or
guides in spaced relation thereto comprising, a
?at body portion of weldable material having 15
one end extended longitudinally to form a spike
adapted for limited penetration into said form
or guide, the tip of said spike being ?attened to
minimize its splitting action when driven into
the form or guide, and the opposite end having 20
an irregular extension transversely bendable
from the plane of said flat body to form a foot
adapted to be welded to a flat surface of said
metal structure member, a side of said extension
in its normally unbent position being transverse 253
relative to the longitudinal axis of said spike.
5. A form clip adapted to be welded to metal
structure members for the support of forms or
guides in spaced relation thereto comprising a
?at sheet metal body having a longitudinally ex
tending spike portion at one end thereof, said
spike being flat at the end and having shoulder
portions at its base which limit its penetration
into the form or guide, said shoulders being
raised at their outer ends so that a portion of the
spike will be visible without the form or guide;
the opposite end of said metal body being irregu
larly extended to provide portions bendable
transversely from the plane of said body to form
feet adapted to engage and be 'welded to the 40
surface of the metal structure member, the
edges of said irregularly extended portions pre
senting ?at surfaces transverse relative to the
longitudinal axis of said spike whereby the lat
ter end of said clip is adapted for abutting
engagement with the edges of said structure
