WEAR. COMPENSATING DEVICE FOR WASH~
ING MACHINE CYLINDER DOORS
William Strobridge, Syracuse, N. Y., assignor to
United States Hoffman Machinery Corpora
tion, New York, N. Y., a corporation of Dela
ware
Application November 14, 1935, Serial No. 49,670
2 Claims. (Cl. 220—32)
This invention relates to wear compensating
devices for washing machine cylinder doors of
the type illustrated in United States Patent No.
1,984,931.
C:
An object of the invention is to ensure the
tight closing of the doors of washing machine
cylinders, both initially and after wear takes
place, by providing simple, eflicient and durable
means for accomplishing this purpose.
The invention accordingly consists in the fea
ll)
tures of construction, combinations of elements,
and arrangements of parts as will be exempli
?ed in the structure to be hereinafter described
and the scope of the application of which will
be indicated in the following claims.
In the accompanying drawings, in which is
shown one of the various possible embodiments
of the invention,
Figure 1 is a front elevation of a fragment of
a cylinder for a washing machine showing a door
hinge and latch assembly embodying the present
invention;
Fig. 2 is a side elevation of the assembly shown
in Fig. 1;
Fig. 3 is a section on line 3--3 of Fig. 1;
Fig. 4 is an elevation of one of the stationary
hinge members for the lower door, showing the
lower end of one of the hinge straps for the
upper door in interlocking engagement therewith,
30 and
Fig. 5 is a section on line 5-5 of Fig. 4.
Similar reference characters refer to similar
parts throughout the several views in the draw
mgs.
Referring to the drawings, 1 represents a wood
en washing machine cylinder of any usual or
suitable construction having in the periphery
at least one dooropening provided with a large
or main upper door 2 and a narrow lower door
40 3. At the lower edge of the door opening is a
wooden sill 4. In order that the door 3 shall
be rigid, it preferably takes the form of a heavy
stiff metal trough into each end of which is
?tted a metal block 5 secured in place by bolts
6 or otherwise. The movable hinge leaves 1 for
the lower door 3 are preferably cast integral
with the blocks 5. The stationary hinge leaves
for the lower door are Z-shaped; each consisting
of a central section 8 adapted to rest on a de
for the hinge leaf sections 8 and II, the sill is '
notched to permit the upright section H to lie
inwardly of the door when the latter is closed,
and the section 8 to underlie the closed door.
At the upper end of each stationary hinge leaf
for the lower door is a lip l2 that projects in
wardly and rests upon the sill. These stationary
hinge leaves are secured in place by one or more
bolts. In the arrangement shown, there are
two bolts for each hinge, a short bolt l3 passing 10
through the lower section and through a cylinder
stave l4 adjacent to the sill, and a long bolt l5
that extends through the lower hinge leaf sec
tion and through the sill.
In order to hold the upper sections of the 15
stationary hinge leaves ?rmly in place, in the
arrangement shown, there is riveted to the in
ner or rear face of each of the hinge leaf sec~
tions H or formed integrally therewith a stiff
metal tongue l6 that extends down a considera 20
ble distance below the central hinge leaf sec
tion 8. Slots out down into the sill at the inner
ends of the seats 9 receive the tongues l6 when
the stationary hinge leaves are set in place.
These slots are preferably so proportioned that 25
the tongues will ?t snugly within them. Each
tongue is provided near its lower end with a
bolt hole l-‘l so located that the corresponding
bolt 15 passes therethrough. Thus, after a sta
tionary hinge leaf has been placed in position
and the two bolts have been applied, the upper
section of the hinge leaf is tied down to the bolt
l5 and is therefore securely anchored to over
come any tendency that it may have to spring
so
away from the sill behind it and thus open a 35
crack or crevice.
As is customary in this type of construction,
the hinge leaves or straps 18 on the upper or
main door are continued past the free end or
edge of that door so as to overlap the lower door 40
sill when the upper door is closed. In the present
construction, the straps i8 are so placed as to
cause them to engage with the outer sides or faces
of the upper sections ll of the stationary hinge
leaves for the lower door. The stationary hinge 45
leaf sections H and the straps 58 are, further»
more, so proportioned and shaped that they be
come effectively interlocked when the doors are
closed, to prevent relative movements circumfer
entially or longitudinally of the cylinder. To this 50
end, each strap I8 is provided at its free end,
on its under or inner side, with a U-shaped rib
the periphery of the cylinder; and an upper sec- . or bead 19. In the arrangement shown, this U
tion ll extending up in contact with the sill shaped rib or bead comprises relatively low ribs 55
2!, 2| at the long edges of the strap l8, and
55 to the top thereof. In order to provide room
pressed seat 9 at the front and below the top of
the sill; a lower section or wing I0, adapted to
rest against the front face of the sill and against

a relatively high connecting cross rib or bead
22 following the lower edge.
Preferably, it should be possible to make such
In the front face
adjustment without removing the stationary
of each of the hinge leaf sections II is a pocket
or depression 20 adapted to receive the ribbed
lower end of the corresponding hinge leaf or
strap I8. Projecting outwardly from the upper
hinge strap from the cylinder. This may be
accomplished by providing at the outer end of the
bolt 28 a pair of small holes 39 adapted to be
end of the inner or rear wall' of the pocket 20
may be turned to a new position from the exterior
is a ledge 23 whose length is slightly less than
the distance between the ribs 2 l, 2! on the strap,v
of the cylinder when the upper and lower doors
l8. Therefore, when the upper door is swung
down, the lower ends of thestraps l8-enter the
pockets 20, the ribs or beads 2|, 2l~ passing the
ends of the ledges 23, and the rib or bead sections
22 underlying the ledges 23. Fig. 5 illustrates the
15 relation between the ledge 23. and the ribs or beads
2| when the upper door is swung down, whereas
Fig. 3 shows the manner in which the ledge over
lies the rib or bead 22.
The doors are locked in their closed positions,
20 as heretofore, by catches 24 on the lower door
engaging with the body of the cylinder. Since
the blocks 5 are properly located for the purpose,
they- are made hollow so as to serve as casings or
housings for. the movable elements of the catches.
25 The chambers in the blocks 5 open out through
the outer ends of the blocks to permit the pas
sage ofthe slidingv bolt elements 25'of‘the catches.
Preferably these catches take into recesses be
neaththe cylinder bands 26 and suitable remov
engaged’ by any suitable key, whereby the bolt
stand open. A set screw 3| is provided to hold
the bolt 28 in any selected position. A seal
strip 32'isecured'tothe outer surfaces of the upper
door hinge straps l8 and extending therebetween
closes. the gap between the lower edge of the
upper door'and the upper edge of the lower door.
The latter door. ordinarily engages this seal strip
and also the lower'ends of the hinge straps l8.
Thus the upper door is ?rmly held in place by the
lower door when the latter is closed and the
catch engaged behind its keeper.
As many possible embodiments may be made 20
of the above invention and as many changes
might‘ be made in the. embodiment above set
forth, it is’ to be understood that‘ all matter here
inbefore set forth or shownin the accompanying
drawings is to be interpreted as illustrative and
not in a limiting sense.
I‘ claim:
'
1. Latching means for adoorhinged'at one edge
of a door opening and having a hinge member
able keeper plates 2'‘! are preferably interposed
comprisinga leaf‘ secured to the door and extend.- "
between the bands and the catches.
Itis essential that the doors be tightly closed,
since otherwise small pieces of wash are likely to
escape through or be caught in the gaps formed
between loosely held‘. doors, or between such doors
ing entirely across the opening, said latching
and the edges of. the door openings. The tight
ness of the doors dependsupon the relation of the
catch and. its keeper. If the keeper and- catch
make tight contact’ when the doors are swung
401 shut and: are. at the limit of their closing move- '
ment, noi troublesome gaps can: be formed.
In
order that the doorsv may be held. tightly. closed
initially and also after wear has taken place,
adjustable means is provided for insuring close
contact between, the catches- and their. keepers.
By reference to Fig.3, this means will. be seen
to comprise a hardened steel stud or bolt 28,
mounted-for. longitudinaladjustment in a thread
_ ed‘bolt hole 29, formed. in the upper section I!
‘ of. the stationary hinge member for the lower
door. The positionofthe said bolt is such that
whenthe upper door isswungclosed, its end bead
22 will come in contact with the outer endof the
bolt. Initially, the bolt is set with its outerv end
' spaced just far enough from the plane of the
inner surface of the catch keeper 21' to prevent
movement of the doors. If, after a period of
service, the doors begin to show looseness, the
bolt may be backed out the small distance neces
sary to“ compensate for the wear that. has taken.
place.
means comprising a ?rst’ member secured to the
door opening in position to be overlapped by the
free end of said. hinge leaf, a second member
hinged uponrsaid' ?rst member and‘ adapted to be "
closed'over said free end, latching means for hold
ing said second member in closed position, and
adjustable means on‘ said‘ ?rst member adapted
to engage the inner surface of said overlapping
hinge leaf, whereby saidhinge leaf. is held tightly 40
between said second member and said adjustable
means.
.
2. Lat‘ching means for a door hinged: at one
