I WILLIAM EXcell Baker of Fairview Redan Hill Aldershot Laundry
Manager do hereby declare the nature of this invention to be as follows:-
My invention has for its object improvements in reversing gear for washing
machines.
For this purpose I use a straight and a crossed belt upon three pulleys the centre
pulley being fixed and the two outside pulleys being loose. To the hub of one of
the loose pulleys I attach a worm for the purpose of driving a worm wheel such
worm wheel having a projecting pin in its side which engages with a box or slotted
bar which is fixed to a horizontal bar so as the worm wheel revolves the horizontal
bar will reciprocate in suitable guides such horizontal bar having the belt shippers
attached thereto. The worm wheel is fitted to revolve on a bar such bar projecting
upwards and engaging with a cam or lever such cam or lever on being operated
will lower or raise the bar and worm wheel thereby engaging such worm wheel with
or disengaging it from the worm. The cam or lever is worked upon a centre
attached to the reciprocating horizontal bar. The lifting bar is provided with a
pin which engages with the cam or lever and is of sufficient length to allow such
cam to reciprocate along the pin with the horizontal bar to which such cam is
attached.
The arrangement may be modified by attaching the cam to operate on the
lifting bar in a stationary position instead of travelling with the horizontal bar.
When the worm wheel is engaged with the worm the horizontal bar with belt
shippers will reciprocate, when disengaged such horizontal bar and shippers. will
remain stationary.
AV shaped notched piece is fixed in such a position that when the lever or
handle of cam is actuated and the worm wheel disengaged from the worm such
lever will have contact with the notched piece and travel along its sloping side to
the centre taking with it the horizontal bar and belt shippers thereby ensuring both
belts being on the loose pulleys.

Manager, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement:-

of one of the loose pulleys I attach a worm for the purpose of driving a worm wheel
such worm wheel having a projecting pin in its side which engages with a box or
slotted bar which is fixed to a horizontal bar so as the worm wheel revolves the
horizontal bar will reciprocate in suitable guides such horizontal bar having the
belt shippers attached thereto. The worm wheel is fitted to revolve on a bar such
bar projecting upwards and engaging with a cam or lever, such cam or lever on

worm wheel with or disengaging it from the worm. The cam or lever is worked
upon a centre attached to the reciprocating horizontal bar. The lifting bar is
provided with a pin which engages with the cam or lever and is of sufficient length
to allow such cam to reciprocate along the pin with the horizontal bar to which
such cam is attached. The arrangement may be modified by attaching the cam to
operate on the lifting bar in a stationary position instead of travelling with the
horizontal bar. When the worm wheel is engaged with the worm the horizontal
bar with belt shippers will reciprocate. When disengaged such horizontal bar and
shippers will remain stationary.
A V-shaped notched piece is fixed in such a position that when the lever or
handle of cam is actuated and the worm wheel disengaged from the worm such
lever will have contact with the notched piece and travel along its sloping side to
the centre taking with it the horizontal bar and belt shippers thereby insuring both
belts being on the loose pulleys.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation and Figure
constructed according to this invention.
an end elevation of reversing gear
a is the washing machine and a' is its shaft to which is fixed the spur wheel a
gearing with the pinion on the shaft b. c is a pulley fixed to the shaft b
and are pulleys loose upon it. The machine is driven by two belts (not shown
in the drawings) one straight and the other crossed so arranged that whilst one is
upon the pulley c¹ the other can either be upon the pulley c or c² and similarly
when the latter is upon e' the first may either be upon c or c¹. d is the arm of the
belt shippers which shift the two belts simultaneously. The arm d is fixed to the
horizontal bar e which is free to slide in guides el e¹ on the frame of the machine.
f is a box or slotted plate (shown separately in front and side elevation at Figures 3
and 4) fixed to and moving with the bar e. g is a worm wheel (shown separately in
front and side elevation at Figures 5 and 6) having fixed to it a stud or roller gl
working between the inclines in the box or plate f. h is a worm on the shaft b and
gearing with the worm wheel g. The working of such apparatus is well understood:-
As the machine is driven by one or other of the belts worm wheel g is revolved and
the roller on it coming against one of the inclines in the plate carries the plate
and with it the bar e to one side so shifting the belts and reversing the motion of
the machine.
-
The worm wheel g is pivotted to the lifting bar j (shown separately in front and
side elevation at Figures 7 and 8) which is free to work up and down in guides in
the frame of the machine. k is a handle pivotted at k to the frame of the machine
and having in it a cam shaped slot receiving a pin j¹ fixed to the lifting bar j.
The slot is so formed that if the handle be turned about its pivot the bar jis
raised and the worm wheel g is lifted out of gear with the worm h. is a forked
guide fixed to the bar e and when the handle is drawn from right to left of Figure 2
it comes against one or other side of the fork and so moves the bar e to its central
position putting one belt onto the pulley c' and the other onto so stopping the
machine.
As above stated the guide / may be fixed to the frame of the machine and the
handle be pivotted to and move with the bar e.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I wish it to be understood
that I do not claim broadly reversing gear of the class described but what I
claim is :-
1. Pivotting the worm wheel to a bar free to move vertically in guides.
2. The combination of the bar j and handle k substantially as described.
3. The combined mechanism substantially as described and shown in the
drawings.
