major portion of its length with a covering `I6 of
sides at the bottom are ñattened out to provide
the flat surfaces 25 so that the housing at itsY
bottom or open end is substantially rectangular
in cross section. The upper end 2_6 of the hous
ing is reduced in diameter and into this reduced 40

Mounted on> opposite sides of the ~lower portion
24 of this covering or housing are pairs of spaced
lugs 21 and 28 upon which are swingably mount
ed the adjusting keepers 29 and 3U. Each of 45
these keepers is provided with an angularly
turnedlug-forming portion 3| and 32 which em- Y
braces the lugs 21 and 28. A pin 29' is projected
through the lugs 21 and'32 and theA lugs 28 and
3l and positioned in embracing relation on this 50
pin 29’ between the lugs 21 and 28 is a coiled
spring 32', one end 33 of which engages the keep-er 29 or 38 and the other end 34 of which en
gages the -bight 35 of the U-shaped memberf‘
which carries the lugs 21 and 28. Each of these 55
keepers is doubled upon itself in the lower end
as at 45 to provide a body through which screws
36 may be threaded. Each of these plates I3
is doubled upon itself and upwardly offset as at

a clamping frame embodying a pair of oppositely
disposed, relatively-movable side bars; a ilexible 5
covering for the major portion of each of said side
bars; means for moving said side bars relatively

to each other for compressing the covering of one
diameter of the head 4| of the screw, so that as

end and the screw head moves inwardly on the
gagement with one face of said clamping frame;
at one end and mounted with its open end in en
inclined portion, the housing will be brought
downwardly relatively to the clamp and secure
ly held in position thereon, thus effecting an
air tight seal between the housing and the clamp
of said engagement members having a portion ex
tended parallel to said frame terminating in an
inclined portion, there being a slot formed 15
which serves as its foundation or base. Formed
on two of the opposite sides of the housing and
through said inclined portion and extending into
said parallel portion; swingably mounted keepers
engagement members carried by said frame, each
projecting outwardly from the edge thereof is
on said housing; and a head-bearing member
a V-shaped tongue 42 which serves to engage at
carried by each of said keepers and adapted for
swinging into said slots for moving said housing 20
into Ysealing engagement with said frame and
the meeting edge of the sleeves I6 and I8 and
effectively close the ends thereof against leak
It will be noted that the slot 40, while ex
tending through the inclined portion 39, also
continues into the horizontal portion 43 so that
as the screw head is forced downwardly on the
inclined portion of the housing is brought closer
into clamping relation with the clamp and base.
As this movement continues and the screw head
moves into the portion of the slot in the hori
zontal portion 43, a locking of the parts in ñxed
relation is effected. It is believed obvious that by
adjusting the screw 36 relatively to the doubled
over portions 35, the degree of pressure exerted
by the housing on the clamp or foundation may
be adjusted.
In use after the parts 'have been assembled as
shown in Fig. l and prior to the delivery of. steam
thereto, it is customary to close the Vent opening
L46 which is formed adjacent the upper end of the
fio housing and deliver air into the housing under
locking the same in such engagement.

keepers mounted on said housing; and a head
bearing member carried by each of said keepers
swingable into each of said slots, the head thereof
engaging in succession said inclined portion and
said parallel portion for moving said housing into
sealing relation with said frame and locking the
same in such relation.
