JOINT CONSTRUCTION
Edgar M. Tucker, South Pasadena, Calif.
Application January 6, 1937, Serial No. 119,216
9 Claims.
This invention relates to joint construction.
The general object of the invention.‘ is to pro
vide an improved joint construction for sealing
the joint between layers of material such as
5 composition roo?ng.
V
A further object of my invention is to provide
a novel ?ashing construction.
A more speci?c object of my invention is to
I provide a ?ashing strip having a novel means for
10
holding a strip in place.
'
7
Another object of my invention is to provide
a ?ashing strip having apertures therein through
which plastic material extends to hold the strip- in
place.
An additional object of my invention is to pro
vide a ?ashing strip having apertures through
which plastic projecting members extend and
wherein a wire mesh member is engagedrby these
20
projections to hold theparts assembled.
A further object of my invention is‘to provide
a ?ashing strip including‘ a‘me‘tal member hav
ing apertures through'whi-ch‘ plastic holding pro
jections extend and wherein these ‘projections vare
locked by mesh members which extend above and
below the ?ashing strip and are secured to the
projections and to the adjacent portions of the
building structure and the up turned roo?ng.
Other objects and the advantages of my in
vention will be apparent from the following de

panying drawings, wherein;

Referring to the drawings by reference char
acters I have shown my invention as embodied
in a roof ?ashing which is indicated generally
at I0.
‘
As shown the ?ashing is arranged in conjunc
tion with a roof deck II and a parapet wall I2. 10
The roof deck is shown as having covering of
plastic material I3 thereon which may be any
suitable preparation and may include asphalt,
coal tar, or other material.
In the application the plastic material is pref 1B
erbly ?rst mopped upon the roof deck I I as shown
in the drawings to a width substantially equal to
that of the‘ roof covering and then a layer of
covering material such as paper I4 is placed upon
the mopped material. This material I4 which I
may be roof paper of suitable composition is
provided with apertures I5 along one of its edges.
These apertures I5 may be of suitable size, con
?guration and arrangement and as shown in the
drawings are circular and are spaced uniformly
apart. When the layer of paper It is laid upon
the plastic material I3 which adheres to the roof
deck II, the paper adheres to the plastic ma
terial and a portion of the plastic material passes
through the apertures I5 and projects above the
paper I4 as shown at A in Figs. 1 and 4 forming
projections.
The roof deck is then mopped with plastic ma
terial for a distance corresponding to the width
of the next layer of roo?ng to be laid and the 35
‘edge of the previously laid layer is mopped as
at I6. The projections A are simultaneously
?attened. Also the lower face of the next layer
is also mopped as at H (see Figs. 2 and 5). As
shown in Fig. 3 the second layer is then swung 40
upward and over so that the parts are‘ brought
into the position shown at It in Figs. 1 and 6
so that the second layer of paper is ?rmly held
in place. The plastic material thus forms a con
tinuous homogeneous mass from the roof deck
I I through the apertures I5 and into contact with
the lower face of the second layer of paper so
that not only is a tight joint provided but the‘
entire area is secured into one unitary'body.
The operation is continued until the parapet 50
wall is reached at which point the edge I9 (as
shown in Fig. 1) of the layer of paper adjoining
the parapet wall is bent up after the parapet wall
has ‘been mopped with plastic as at 20. This
plastic passes through the apertures I5 in this 65.

member 26 as shown in Fig. 1.
As a result of
3.0 this construction the roo?ng and ?ashing are held
as one unit by the homogeneous interlocking pro
jections A, B, and C formed by the plastic ma
terial which passes through the apertures. Nails
3!! may be employed to hold the parts assembled
until the plastic sets.
In Fig. 11 I show a modi?cation of my inven
tion wherein shingles 46 are provided with aper
tures 4| at one end.
The roof deck receives-a
coating 42 of plastic material which passes
5.
through the apertures 4| and as each course of
S
shingles is laid and is secured as by nails 43, the
plastic material passes from the roof deck through
the apertures 4| and engages the lower face of the
portion of each shingle thereabove.
In Figs. 8, 9 and 10 I have shown a modi?ed
In Fig. 13 I show a modi?ed form of metal strip.
This strip indicated generally at 55a includes an
upper portion 56a, a lower portion 51a and an
intermediate portion 58a. This intermediate por 85
tion is formed similar to the intermediate portion
58 previously described and the strip shown in
Fig. 13 differs from the strip previously described
only in that apertures 59 triangular in shape are
arranged with their bases reversed.
40
In Figs. 14 and 15 I show another strip indi
cated generally at 56b which is similar to the
strip! 55 previously described except that the
upper and lower portions are provided with out
struck tongues 59b which leave apertures 590 in 45
type of ?ashing which is indicated generally at
the material.

junction with a roof 5| and a parapet wall 52.
ranged staggered in two rows so that the tongues
assume the position shown in Fig. 15. The use
of the strip shown in Figs. 13, 14 and 15 is similar
to that shown inconnection with Fig. 12.
50
From the foregoing description it will be ap
parent that I have invented a novel joint con
The roof has a covering 53 which may be a com
position roo?ng which has an up turned portion
54 engaging the parapet wall 52. This portion 54
is covered by a base ?ashing 54A which extends
upwardly as at 54B..
My ?ashing as shown includes a metal strip 55.
This strip 55 includes an upper portion 56, a lower
portion 51 and'an intermediate portion 58. This
intermediate portion comprises a plurality of lay
ers of the strip preferably bent ?at upon them
selves as shown. The upper portion 56 is pro
vided with'apertures 59 while the lower portion 51
is provided with apertures 66.
In use a coating of plastic is placed upon the
parapet wall 52 and the strip 55 is also covered
with plastic on the rear side thereof and the strip
65 is then disposed immediately above the upper end
of the portion 54B and is pushed in place thus
forcing the plastic through the apertures 59 and
These tongues are shown as ar
struction which is useful in the laying of roofs,
in ?ashing, and which in fact may be employed
generally wherever it is desired to unite overlap 55
ping layers of material and to secure the over
lapping layers together as a unit and to secure
them as a unit to the structure on which they are
applied. With my invention it will be apparent
that economy of manufacture and an assurance 60
of a tight joint is secured.
Having thus described my invention I claim:
