The diameters of the holes in the plates .andv in the angle to the corner of the angle, three

the angles are preferably l/zf’ and the center to
center spacing of the holes is one inch. Thedis
tance from the center line of the holes in the
angle to the corner of said angle is two inches, or
twice the center to center spacing of the holes.
Furthermore, the distance between the center
lines of parallel rows of holesin theplate is four
30 times the spacing of the holes one way and eight
times the spacing of the holes the other way. ,
A 1/2" bolt ‘7/3” long is used to connect the var
ious members. The thickness of the angles and
plates may be 1/8" so 1%" shank without threads
is required on the bolt for connecting a- plate to
two angles, and when but one plate and one angle
are connected. together making 1A," thickness,
then a washer 1A" thick is used to ?ll out'the un
threaded portion of the bolt. The thread of the
40 bolt is slightly less in diameter than the 1/2” hole
and permits the nut to pull the bolt through, thus
assuring a tight ?t.
Another object of my invention is to provide
means of increasing the strength of these mem
different sizes of members on either axis of the
plate as shown in Figs. 10 to 21. When the plate
is connected to angles short side up 6", '7'f and 25
8" depth‘of members-can be formed and when
the plate is connected to angles long side up 10'’,
11" and 12” depth members can be formed.
\Vhen two plates are adjacent to form connec
tion plates as in Figures 28 and 39, additional bolts 30‘
may be inserted under these plates, as at H, in
order to assist in supporting the load. The edge
of the plate would contact the bolt asthere is a
Mo," metal between the edge of the plate and the
edge of the hole and the holes are 1/2" diameter. 35
The holes shown, on plate “a” are spaced as
shown for several reasons. The 1/2” holes suit
1" spacing around the edges of the plate and
there is a 4" and 8” spacing respectively between
the center lines of the parallel rows of holes.
40
The holes l2 located between the two parallel
rows of holes are, centered to match the center
line of the outside rows of holes. Three of these
holes are positioned near each end of the long
45
45 bers by introducing perforated plates between the side ‘of the plate.
I may add additional holes and I may space the
?ange angles or introducing additional close-?t»
ting angles on the outer side of the ?ange. , ~

It is important for several reasons that the
width of the plate be eleven times the diameter
of the 'holes and that the length of the plate be
nineteen times the diameter of the holes;
I may add a washer to the head end of the bolt 55'.

or make the head wider to secure greater bear
ing area to prevent any tilting of the ?ange an
gles also I may add a separate clip across the two
adjacent angle ?anges, the clip being bent over
and under the two horizontal legs of the angle
to prevent their spreading or tilting and I may
add additional bolts to the ?ange angles between
the web plates to also prevent any tilting or
spreading of the ?ange angles.

Figures 2 and 3 show an angle “b” having a row
of 1A9,” holes on 1" centers, 34" from an edge and
2” from the center line of said holes to the corner
of the angle. I prefer to use an angle being 2”
on one leg and 2%” on the other. Figure 4
15 shows 1/2" bolt “0”, %" of the stock being with
out threads. Figures 5 to 22 show an end view of
various structural shapes and sizes of structural
members all using in combination angle “b” and
bolt “0” or angle “19”, bolt “0” and plate “a”. In
20 other words all the ?anges shown in these various
structural members are made up of multiples of
‘a single perforated sized angle, some of which are
connected together with multiples of a single
sized bolt and others connected together with
25 multiples of a single sized perforated plate. One
leg of angle "22” has no holes.
Figure 23 shows how these members may be
reinforced to carry additional loading by in
corporating additional angles “as” closely ?tting
to the flange angles “13”. Either square root
angles or round corner angles may be employed.
Figure 24 shows an alternate method of rein
forcing these structural members wherein perfo
rated metal strips “y” are secured between the

Figure 36 shows a stud formed of two angles

Figure 37 shows a framing detail wherein an 10
angle connection can be made with two plates
“a” “a”. The holes located on these plates are
so arranged that a great variety of different
angles may be formed in framing. Angles “b”
may be connected to these plates “a” to form a
variety of framing combinations.
Figure 38 shows structural framing wherein a
connection angle “e” is secured to angles “b” to
permit convenient spacing of members along the
holes in angles “1)”.

Figures 25 and 26 show beams made up of

introduced between the ?anges where bolted,
thereby stiffening the ?anges of the beams.
Figure 27 shows a girder with plate “a” form

connection angle “6” is made up from scrap
pieces left over from ?ange angles “b”.

Figure 29 shows splice plates “a” extending
beyond ?anges “b” to form connection plates.

that each ?oor would be supported entirely by its
