CROSS ARM MOUNTING HANGER
Allan Ramsey, Evanston, Ill., assignor
to
Schweitzer & Conrad, Inc., Chicago, 111., a cor
poration of Delaware
Application September 14, 1936, Serial No. 100,697
3 Claims. (Cl. 248-226)
The present invention relates to adjustable
cross arm mountings or hangers for supporting
primary cutouts or the like, in overhead manner,
upon a supporting structure such as a wooden
5 cross arm. The present application is a continu
ation in part of my copending applications, Serial
No. ‘734,262, ?led July 9, 1934, and Serial No.
730,075, ?led June 9, 1934. The hanger of the
present invention is adjustable in size to adapt
10 it to mounting upon cross arms of different sizes,
and in various combinations with a device to be
supported. A suitable intermediate connecting
bracket may be employed whereby the devices,
such as a fuse box, cutout, switch or the like may
directly in line with one surface of the cross arm.
Thus, for example, instead of having the mating
ears extend directly in line with the bottom sur
face or the side surface of the cross arm, the par
allel mating ears may extend at any suitable
angle.
A further feature of novelty of my invention
is to arrange these two sections of the hanger
which carry the mating clamping lugs or ears so
that they may be interchanged in position. In 10
the speci?c form illustrated the two sections ex
tend an equal distance from the common corner.
This is an optional re?nement providing an ad
vantage as to interchangeability. Where the two
15 be supported optionally in any one of a number ‘ sections thus extend equal distances from the 15
common corner they may be reversed in position
of positions with respect to two axes of angular
ity. Two speci?c devices which I have illustrated
are a fuse box and an ejector cutout such as may
be included in a primary circuit on the high ten
20 sion side of a distribution transformer. The spe
ci?c fuse, switch, or other electrical device to be
supported is not of the essence of the invention,
these devices being shown by way of illustration
and not by way of limitation.
25
Particular features of improvement of the pres
ent hanger are, ?rst, its adaptability to various
sizes of cross arms and various positions; next, its
relatively low cost; and third, its simple, rugged
character.
30
Preferably, the sections of the hanger are made
of strap iron formed to shape. The strap iron
body section is provided at its ends with lugs ex
tending at a selected angle or angles so as to
match with lugs of another section or sections,
without altering the position of the remainder of
the hanger. This is of considerable advantage in
that it allows the angular position of the clamp—
ing ears to be altered without requiring any 20
change in the remainder of the hanger. Where
the intermediate bracket member has a mount
ing lug angularly disposed with respect to its body
portion, various selected intermediate positions
of the supported device may optionally be had 25
from the same parts. Intermediate bracket
members of various forms may be employed.
In order to acquaint those skilled in the _art
with the manner of constructing and operating a
device embodying my invention, I shall describe, 30
in conjunction with the accompanying drawings,
a speci?c embodiment of my invention.
In the drawings:
Figure 1 is a view taken from the side of a

which mating clamping ears or lugs form an
40 anchorage for the intermediate bracket member
that supports the device to be carried from the
cross arm. The body portion of one section lies
at right angles to the body portion of the adja
cent section but the ears which are integral with
45 these two body portions extend parallel to each
other at the corner of the angle de?ned by the
body portions. This relation is secured by hav
ing the ear or lug form a direct continuation of
one body portion, and having the ear or lug of
50 the other body section bent at right angles to the
corresponding body portion. While this right
angle relation of the two lugs as above indi—
cated is the preferable one, it is obviously not the
only one, since the ears lying parallel to each
55 other may extend at any selected angle instead of
of the same on a cross arm;

ing generally of sections of a peripheral encircling
band clamped thereupon for supporting the pri
mary fuse box 3 in convenient position to be
opened, re-fused, and. closed by a lineman on a
pole or other structure for supporting the cross
arm I.
As shown in Figures 1 and 2, the fuse box 3
which has at its rear end the diagonally extend
ing bolting lug 30 meeting with the lug 27 of the
segment 24. The lug extends from the body por
tion of the segment 2 a short distance from the
corner of the wooden cross arm I so that the bolt
28 may tend to‘ pull the segment 21 both hori
zontally and vertically.
At its front end the segment 29 has an oifset

'
The hanger 2 comprises an encircling band
which may be tightened about the cross arm I to
secure a ?rm mounting for the same. This en
circling band comprises, in the form shown in
Figures 1 to 10, four segments. These segments
35 comprise the front segment I5, the bottom seg
ment I9, the back segment 24, and the top seg
ment 29. The front segment I5 and the bottom
segment I9 have mating clamping ears I1 and
20 clamping between them, by means of the bolt
I8, the lug or ear I3 of the bracket member I2.
The bolt I8 is preferably a carriage bolt having
a square shank under the head and the ‘lugs pref,
erably have square holes therethrough so as to
facilitate the assembly of the device. Obviously;
45 machine bolts instead of carriage bolts may be
‘employed.
'
The front segment I5 has the lug I6 bent up
at right angles to. the body portion of the section
I5 and likewise the bottom segment I9 has the
50 clamping ear or lug 22 bent up at right angles to
its main body portion.
These four body seg
ments are all made of bar or strap iron suitably
formed to shape and perforated, fromv the same
or like bars of stock.
5.5
Attention is called'to the fact that the lug I6
of the body portion I5 and the lug 22 of the body
portion I9 lie at equal distances from the com
mon angle de?ned by the body portions I5 and
I9. It will be seen that the body portion I5 does
60 not extend quite to the corner because of the
thickness of the lug I3 of the intermediate brack
et I2. Obviously, however, the body portion I5
might be extended to the corner and the ears
or lugs I ‘I and 20 clamped ?at against each other
65 with the lug I3 of the intermediate bracket mem~
ber I2 placed above or below these mating lugs.
The back segment 24 has a diagonally ex~
tending ear or lug 21 which extends off from a
point adjacent the top rear corner of the cross
70 arm I. At its lower end the body portion 24 has
an offset portion 25 and a bolting ear or lug 26
which is perforated and matches with the ear 22
of the body segment I9 so that the carriage bolt
75
23 may clamp the lugs 26 and 22 together,
The top segment has a curved body portion
variety of sizes of cross arms may be satisfac
torily clamped by the same four segments as
shown in Figures 7 to 10. In Figures 7 and 8 the
bolt 28 is a %" x 2" carriage bolt, the bolt 33 is a
%” x 1%" carriage bolt, the bolt I8 is likewise
a 1%" x 11/2" carriage bolt, and the bolt 23 is a 30
%" x 21/2" carriage bolt. With the same seg
ments and the aforesaid bolts,rcross arms rang
ing from 31/2" x 4%," to 3%" x 4%" may be
embraced and held with the clamping lugs I1
and 29 disposed in horizontal position as shown 35
in Figure 7, or in vertical position as shown in
Figure 8, by reversal of the. relation of the seg
ments I5 and I9.
In Figures 9 and 10 the bolt 28 is a %" x 31/2"
carriage bolt, the bolt 33 is a 1V8,’ ' x 2%” carriage
bolt, the bolt I8 is a %” x 11/2" carriage bolt,
and the bolt 23 is a %" x 2%” carriage bolt.
With this arrangement of bolts, cross arms from
3%," x 5%" to 4" x 6'.’ may be clamped.
It will be observed, in the form shown in Fig 45
ures 7 to 10, thatthe o?fset portion 25 shown in
Figure l is omitted. The o?set portion 25 is of
advantage in securing a grip upon the lower rear
corner of the cross arm when the bolt 28 is drawn
up tightly, but an adequate support may be ob
tained by the construction shown in Figures 7 to
10.
50
Obviously, where the same size cross arm is
to be clamped and the full desideratum is in ad
justability from the horizontal to the vertical po
sition of the lugs I1 and 20, the two segments 24
and 29 may be merged into a single piece, as
shown diagrammatically at 35 in Figure 11,.
In Figures 3 and 4 I have illustrated an inter
mediate bracket member 36 which is .a strap
ironbent to an acute angle for permitting the 60
box 3 to be mounted in a substantially vertical
position, as shown in Figure 4, or by swinging
the box 180° on the pin 3‘! which clamps the
bracket 38 to the back of the box 3, the box may
be swung to substantially horizontal position, as
shown in Figure 3, the clamping ears I1 and 26
in this case being swung from the horizontal
position shown in Figure 4 to the vertical posi
tion shown in Figure 3.
In Figures 5 and 6 I have shown the mounting 70
of a so-called ejector cutout for primary circuits.
This ejector cutout 38 comprises a tubular body
portion 39 and a plug portion (not shown) car
ried on a handle member 40.
The plug member
is a fuse which has cooperating contacts in the
3
2,108,343
tubular mounting 39. The contacts in the tubu
lar body 39 are connected to the primary wires
which enter at the holes 4| and 42. In order to
mount the ejector cutout 38 in either the sub
stantially horizontal position shown in Figure 5
or the substantially vertical position shown in
Figure 6, an intermediate bracket member 43
having a lug or car 44 adapted to- be clamped
between the ears I1 and 2|] is provided. . This
bracket member 43 has a split band clamp 45
encircling and gripping the cylindrical part of
the tubular housing member 39. Bolts 46 and 41
hold together the two parts of the split clamp
which connect the bracket 43 with the said tubu
15 lar body 39. It will be observed that the mount
ing lug 44 of the bracket 43 extends not at right
angles to the split clamp portion 45 but at a
little more than a right angle, whereby in Fig
ure 5 the handle portion 40 is inclined slightly
20 upward from horizontal and in Figure 6 inclined
slightly to the right of vertical, for ease in han
dling. In addition, there is the adjustability piv
otally on the axis of the bolt I8.
A suitable
spring lock washer may be provided under the
25 nut of the bolt l8 to avoid loosening by repeat
ed handling of the supported device. The resil
iency of the wooden cross arm obviates the ne
cessity for spring washers under the other bolts.
Where adjustability as to size of the cross arm
30 is required the drawing up of the various bolts
will accomplish one degree of adjustability and
permit the hanger to be clamped upon the cross
arm. Where wider variation is encountered the
length of the bolts may be adjusted, as above ex
35
plained.
The lugs I‘! and 2!) may, if desired, be extended
off diagonally from the corner at a suitable in
clination to- give greater or less angular throw
by reversal of the parts l5 and I9. Thus it may
40 be seen that if, in Figure 1, the lugs I1 and 20
were bent upwardly with respect to the horizon
tal, then when they are changed to the position
shown in Figure 8 they would extend to the left
of the vertical and thus produce a greater de
gree of difference in angle between their two re
spective positions.
As I have above indicated, the two sections 29
and 24 may be merged into a single piece where
the degree of adjustability herein indicated may
not be required. Thus, as shown in Figure 11,
50 the adjustability of the position of the lugs l1
and 20 may be provided even though no adjust
ability as to the size of the cross arm were pro
vided.
The ears I‘! and 23 may be provided with suit
able roughening of the clamping surface as by
stamping with a die about the bolt holes to in
crease the frictional grip upon the lug I3 of the
bracket IE, or like lugs of brackets such as 43
60 and 36. The lugs of the brackets I2, 36 and 43
55
65
ample the ear l3 of the bracket I2 clamped be
tween the ears I‘! and 20 by the bolt I8, Figure 1,
the gripping action of the parts forming the cross
arm hanger is unaffected thereby.
There is a
certain degree of independence between the
clamping of the lug or tongue of the electrical
device and the gripping action of the hanger with
respect to the cross arm.
Both actions may be
properly effected without requiring close ?tting 10
of the various parts involved and both clamping
or gripping actions are available using the same
hanger parts for a considerable range of sizes of
cross arms and thicknesses of lugs or tongues.
I do not intend to be limited to the speci?c de 15
tails nor the speci?c forms or proportions illus
trated and above described in detail except as the
same are recited in the appended claims, as it
is obvious that a fairly wide variation of the de
tails of my mounting from the above teachings 20
will at once be apparent to those skilled in the
art. The advantages and mode of operation of
the device are obvious from the foregoing descrip
tion.
I claim:
