The present invention is designed to improve
the connection between a wringer and its support. that the openings I'I and in consequence the
Power wringers as ordinarily made are formed
as a unit and secured to a wringer support, this
5 support usually providing a means through which
to> transmit the power to the Wringer. The
wringer in use is subjected to very frequent
strains which are carried into, or through the
connection and which tend to loosen the connec
Yl0 tion between the Wringer and its support. With
the present invention a stile of the wringer is
provided with projections which extend into sock
ets in the support, these projections and the Walls
of the socket taking a large part of the strain
through the connection. Preferably the secur
ing studs extend directly through the projection
into the support, the heads of which are prefer
ably housed within the projection. Features and
details of the invention will appear from the
20 specification and claims.
A preferred embodiment of the invention is
illustrated in the accompanying drawing as fol
Fig. 1 shows a vertical section of an end of a
25 wringer and a part of its support on the line I _I
in Fig. 2.
Fig. 2 an end view of the wringer removed from
its support and partly in section on the line 3-3
in Fig. 1.
Fig. 3 a front elevation of the wringer.
Fig. 4 a central section of a modiñcation.
I marks the base of the wringer frame, 2 the
side stiles and 3 the top bar. These are ordi
narily constructed of sheet metal, the side stile
35 being usually of box form with slots 4 on their
inner faces through which shafts 5 and 6 oi'
wringer rolls ‘I and 8 extend. Journal boxes 9
and I 0 are arranged Within the stile, the upper
journal box being slidably supported therein and
40 subject to pressure from the usual pressure
spring II.
The power shaft of the wringer is coupled ordi
narily with a shaft I2 extending through a sup
port I3. 'I‘he support is provided with sockets I4
45 on the face next the wringer stile and the wringer
stile is provided with projections I5 which ex
tend into these sockets. These projections are
preferably formed by striking them up in the
sheet metal yforming the outer side Wall of the
50 box-shaped stile. Studs I6 extend through open
ings Iï extending through the walls of the pro
jection and these studs extend into screw-thread
ed openings I8 in the support I3. Heads I9 of
the 'studs are housed within recesses 20 formed
55 at the rear of the projections. It will be noted
heads of the studs are directly opposite the slot 4
so that the studs may be readily put in place
through this slot and the studs set up by tools
extended through the slot.
Preferably there is little clearance between the
end of the projection and the bottom of the recess
and a slight clearance between the face of the
support and the wall of the stile and the walls of
the projections and recesses are slightly conical l0
so that as the studs are set up there is a pressed
engagement between the walls of the stud and the
Walls of the recess which forms a very rigid and
secure connection between the support and the
wringer. The slight resiliency of the metal form- 15
ing the rear stile as it is drawn up tends to main
tain the rigidity of the connection in use.
With this construction the connecting studs, or
bolts, are entirely sealed so that the supporting
walls of the wringer support may be entirely 20
free from obstructions thus making it easier to
fabricate and to plate, or polish, and also permit
ting of a more attractive structure and one more
readily kept clean.
In Fig. 4 I have shown a modification in which 25
an outer ‘wall 2a of the stile is provided with a
slight indentation 2I which has an opening
through it. A cup-shaped ñtting 22 is arranged
in the opening in the indentation 2| and this is
provided with a flange 22a which is arranged in 30
the recess formed by the indentation. The fitting
has an opening 23 which is adapted to receive a
stud 24 for securing the wringer to a support.
The stud head 25 is housed in a recess 26 formed
by the fitting.
What I claim as new is:
1. A wringer frame comprising a side stile of
box form having a shaft receiving slot on its
inner side and a projection on the outer wall of
the stile opposite the slot, said projection being 40
adapted to engage a recess in a wringer support
and having an opening for receiving a securing
2. A wringer frame comprising a side stile of
box formation having a wringer shaft slot in its 4,5
inner Wall and a plurality of projections in its
outer wall opposite the slot, said projection being
adapted to engage sockets in a wringer support
and having openings therethrough adapted to
receive securing studs.
3. A wringer comprising a side stile of box form
having formed on the outer Wall thereof a mem
ber of a projection and socket connection for a
support, the inner wall of the stile being slotted
and the outer wall having a screw-receiving open-- 55
ing opposite the slot in close relation to the
4. In a wring-er, the combination' of a stile of
box form having a projection on the outer wall
with a perforation through the projection and a
recess within the stile at the rear of the projec-V
tion; a wringer support having a recess receiving
the projection and a screw-threaded opening in
alinement with the ‘opening through the recess,Y
the peripheral walls of the projection and recess
being included and in direct wedging contact;>
and a screw extending throught the opening'in
the projection into the screwf'threaded opening` inv
the support and having its head housed in the
wringer support having between them recess and
projection securing members having included pe
ripheral walls in direct wedging contact and a
screw extending through'the projection and walls
'of the recess and drawing said peripheral walls
into engagement, said screw being opposite the
» opening in the inner wall of the stile and oper
able through said opening.
