that the contacting face of the crown brass
may be suitably lubricated.
Fitting between the lower end portions
of the walls or side members 2 of the box
5 is a lubricating cellar C "which has one end
portion anchored to said walls or side mem-
bers by a pin 10 extending through an open-
ing 11 in the cellar C and through an open-
ing 12 in the lower portion of each of the
10 walls or side members 2. The opposite end
portion of the cellar C is provided in its
side walls and adjacent the top thereof with
an inwardly and downwardly inclined,
open slot or recess 14 which is adapted to
15 receive a lug 15 whereby a further sup-
porting means is provided for the cellar
C. The lugs 15 are preferably arranged ad-
jacent the outer or hub face of the box and
in applying the cellar the same is engaged
20 with the lugs 15 before the pin or rod 10
is applied.
The hub faces of the arch 1 and the walls
or side members 2 are flat and unobstructed,
except for the vertically disposed and out-
25 standing T-head 16 arranged at the central
portion of the arch 1.
The hub liner comprises two sections 17
substantially in duplicate, and the outer
side marginal portion of each of said see-
30 tions is provided with a flange 18. The
lower end portion of the flange 18 is con-
tinued by a transversely disposed block
pocket 19 extending across the adjacent por-
tion of the section 17 while the upper por-
35 tion of the flange 18 is provided with a lug
20 extending partially along the upper por-
tion of the section 17. The lug 20 is ta-
pered two ways, and has its inner face a
inclined downwardly and inwardly for co-
A4 action with the lug face b provided at an end
portion of the wall of the box, these being
so tapered as to cause the flange hub plate
to fit close against the wall of the box and
tighten when bolt 30 is so adjusted.
45 In applying a section 17, the lug 20 is
first engaged with the upper portion of the
arch 1, and with said lug serving as a ful-
crum, the lower end portion of the section
17 is swung inwardly so that the block
50 pocket underlies a shoulder 21, which is
inclined upwardly and inwardly in a direc-
tion transverse of the wall or side member,
while the upper face 23 of the block pocket
is inclined upwardly and inwardly.
55 The inner edge of the upper portion of
the section 17 is provided, longitudinally
thereof with a groove or channel 24 which
engages a side portion or flange of the T-
head 16 whereby the upper portion of the
60 section 17 in conjunction with the lug 20
is effectively held in applied position.
The upper part of the block pocket 19
is provided with the pocket 25 in which is
mounted a block 26, and the upper face
65 of the block pocket 25 and block 26 is in-dined or beveled to correspond with the in-
clination of the shoulder 21. The block 26
rests upon a nut or similar member 27 in-
sertible within the lower or base portion
of the pocket 25 through a laterally ex- 70
tending opening 28 formed in the lower
portion of the section 17. The lower end
of the section 17 is provided with an open-
ing 29 communicating with the pocket 25
and through which extends a bolt 30 75
threaded through the nut 27. The upper
or inner end of the bolt 30 engages with
the lower face of the block 26 so that upon
requisite rotation of the bolt 30, the block
26 is forced upwardly into engagement with so
the shoulder 21, whereby the lower portion
of the section 17 is effectively locked in
working position upon the box.
On account of the use of the block 26, it
is not necessary that the shoulder 21 be 85
machined, nor is it necessary that the work-
ing face of the block be machined, as bolt
30 can be operated to adjust the bolt to
compensate; for any inequalities of wear.
When it is desired to 'apply a section 17, 90
bolt 30 is removed and the nut 27 forced
into the opening 28 to permit the block
26 to drop to its lowermost position and to
a position whereby no obstruction is offered
to the requisite swinging movement, of the 95
section 17.
The opposed faces of the flange 18 of
each of the' sections 17 and the adjacent
face of the wall or member 2 are provided
with elongated grooves or recesses 31, each 100
substantially semi-circular in cross section,
and which grooves or recesses are in reg-
ister when the section 17 is in applied posi-
tion upon the box. 32 denotes an elongated,
cylindrical bar or filler of a length less than 105
the length of the recesses or grooves 31,
and which bar or filler 32 seats within such
recesses or grooves to provide further means
for maintaining the section 17 in applied
position. The lower end of the bar or filler 110
32 is beveled, as at 33, to seat within an
undercut or dove-tail 34 in the wall at the
lower end of the recess or groove 31 in the
wall or member 2, whereby said bar or filler
is maintained in desired position while the 11 5
section 17 is being applied.
By having the bar or filler 32- of a length
less than the recess or grooves 31, provision
is made for the desired relative longitudinal
movement of the section 17 and the box 120
when the section 17 is being pulled down to
effect the desired engagement of the sec-
tion with the box.
The inner vertical margins of the outer
faces of the walls or side members 2 of the 125
box are also provided with the outstanding
solid flanges 35. The flanges 18 and 35 co-
act with the pedestal in a conventional man-
ner, and the opposed faces 36 of said flanges
18 and 35 are longitudinally curved or 130
