" The general object of my invention is to provide a vacuum cleaner conduit including novelly
5 connected detachable sections.
4A- more speci?c object of the invention is to
provide a novel detachable connection for a vacuum cleaner conduit,
_
Another object of theinvention is to provide
10' a novel means for connecting a vacuum cleaner
conduit to a cleaner body.

2|. I preferably'provide two clamps l9 and as a
third securing member I may provide a clip 22
mounted on the housing and projecting over the
top of closure 18. The closure I8 is notched as
at 23 to receive the clip and to aid in centering.
5
From the closure l8 an offset conduit 24 ex
tends- This Conduit is provided With an enlarged
cylindrical skirt portion 25 in which a collar
26 on a cap 21 is arranged The Conduit portion
24 is engaged by a clip 23 similar to Clip 22 and 10
which projects through a notch 29 on the cap 21.
An additional object of my invention is to provide novel means for connecting a vacuum cleaner
handle to a ?exible hose,
' The Conduit member 24 is provided With a hail‘
of Securing members 30 which are shown as con
nected by screws 3| to bosses 32 and which en
Other objects and the advantages of my invention will be apparent from the following description taken in connection with thevaccompanying drawings wherein:v
Fig, 1 is the side elevation of a vacuum cleaner
showing my invention attached thereto;
Fig. 2 is a fragmentary sectional view through
the closure and conduit;
Fig. 3 is a top plan of the closure;
Fig. 4 is a section taken on line 4--4 of Fig. 2;
Fig. 5 is a detail side elevation showing the securing clamp;

Fig. 9 is a fragmentary elevation showing details of the joint; and
Fig. 10 is a section taken on line l0-—l0 of
Fig. 9.
This application is a continuation-in-part of
my co-pending application, Serial No.‘ 58,491,
?led January 10, 1936, which matured into Patent No. 2,112,978.
Referring to the drawings by reference characters I have shown my invention as embodied in
a vacuum cleaner which is indicated generally at
gage the Cap (as shown in Fig- 4) to hold the
Cal) in place. SWiVellY mounted in the Cap 27, I
arrange a tubular member 33 which is ?ared
at its inner end as at 33' to prevent removal but
to allow the member to swivel on the cap. The
Conduit proper at one end Comprises a rubber
hose 34 which'is ?tted within the tubular mem
ber 33 and secured by cement while the other
end of the conduit comprises a metal handle por
tion which includes a plurality of sections des
ignated 35, 36, and 3'! with the section 35 slightly
curved. It is to be understood that the number
of sections can be varied without departing from
the features of my invention.
The end of the handle member adjacent to the
hose is connected thereto by a swivel member 38
which as shown in Fig. 7 includes an enlarged
portion 38' on the end of the tube portion 35
with the enlarged portion having an outstanding
?ange 39 thereon which is connected to a cylin
drical portion 40 which has inwardly directed
flange 41 thereon. The hose 34 is cemented in a
collar 42 which is flared as at 43 at the end
to allow flexibility in the hose
The Collar 42 is provided intermediate its
length with a flange 44 which engages the ?ange
39 as shown in Fig- '7- A split spring member 45 is
disposed in engagement With the ?anges 4| and 44
to thereby allow a swivelling action between the

' I0. As shown the cleaner includes a housing I I
45 in which a suitable motor and fan may be
mounted.
The upper portion I2 of the housing is provided with an annular ring I4 which is secured
in place by means such as bolts l5.
50
The ring is rabbeted at IE to receive a ?anged
collar I‘! on which a fabric dirt bag Bis mounted.
The ring I4 is provided with a closure I8
which is held in place by securing clamps [9 which
are pivoted by screws 20 to the housing. The
handle and the hose Without longitudinal move
ment between these parts45
The section 35 is connected to the section 36
and the section 36 is connected to the section
31, each by a joint 50. Each joint 50 includes an
expanded portion 5| which terminates in a bulb
ous bead 52 and includes an outwardly pressed 50
boss 53 on which a locking lever 54 is pivoted
by means of a rivet 55. The locking lever in
cludes a ?nger engaging portion 56 on one side
of the pivot and a hook portion 51 on the other
55 clamps [9 each include ?nger engaging portions
side of the pivot. The hook portion has a slot 55
2
2,122,633
which is indicated at 58 and which has an under
cut face. The bulbous portion 5| is notched as
at- 50 with the notch so disposedv that it is in
alignment with the slot when the lever is in one
UT
position.
.
The portion of the section 31 adjacent to the
section 36 is provided with a protruding head 62
against which a gasket 63, which may be an in
expensive rubber band, is ?tted and beyond the
10 bead the section 35 is cylindrical as at 64. Be
yond the cylindrical portion 64 the length is
slightly tapered as at 65 to allow ready assem
blage. The tapered end 65 is arranged
the
direction of ?ow as indicated by the arrow in Fig.
15 10 so that there is no likelihood of dirt lodging
in the joint.
In assembling the parts the locking lever‘ 54 is
moved to open position and the lengths are
moved to the position shown in Figs. 9 and 10.
20 The locking lever is then swung on its pivot 55
and engages a post 66 on the cylindrical portion
63. The post is ?tted within the notch Bl] on
the bulbous portion 6| and when the lock lever
turns this post is engaged between the walls of
25 the slot thus bringing the parts together and
compressing the gasket 63.
The lower portion of the forward end of the
?nger engaging portion 36, as indicated at ‘61,
presses against the adjacent portion of the
iength 34 and the friction thus developed be
tween these engaging portions serves to hold the
parts assembled. Attached to the outer end of
the length 31 I show a swivel 19 which may be
connected to a suitable nozzle 'H.
The nozzle,
35 however, forms no part of the present invention
and is merely typical of a number of implements
which may be secured to the handle portion.
From the foregoing description it will be ap
parent that I have invented a novel vacuum
40 cleaner conduit which can be readily manufac=
tured and which is highly e?icient in use.
Having thus‘ described my invention, I claim:
1. In a vacuum cleaner,‘ a conduit, a handle
member comprising a plurality of lengths of hol
low tubes, said tubes ineluding inner and outer
telescoping end portions, said inner end having
a bead therein, said outer end having a periph
eral outwardly extending bead adjacent to the
bead on the inner portion, said outer end hav
ing a boss thereon, a locking lever pivoted on
said boss, said inner tube having a post thereon, 10
said outer tube having a straight slot in said
boss receiving said post, said lever including a
hand engaging portion at one end and including
a transversally extending notch spaced on the
15
other end of said lever receiving said post.
2. In a vacuum cleaner, a conduit, a handle
member comprising a plurality of lengths of hol
low tubes, said tubes including inner and outer
telescoping end portions, the inner end portions
including a cylindrical portion and an inwardly
tapered extremity, the outeryend portions com
prising a cylindrical portion, an outwardly ta
pered portion and a cylindrical extremity on the
outwardly tapered portion, said cylindrical por
tion on the outer end portion being disposed con
tiguous with the cylindrical portion on the inner
25
portion, said inner end portion having a bead
therein, said outer end portion having a periph
eral outwardly extending bead adjacent to the 30
bead on the inner portion, said outer end por
tion having a boss thereon, a locking lever piv
oted on said boss, said inner portion having a
post thereon, said outer portion bead having a
straightslot receiving said post, said lever in 35
cluding a hand engaging portion at one end and
including a transversally extending notch spaced
on the other end of said lever, said netch receiv
ing said post.
