PROVISIONAL SPECIFICATION.
Improvements in Reversing Gear for Washing, Wringing, Mangling,
or other similar Machines.
I WILLIAM LITLER BRADFORD of The Crescent Iron Works Salford in the
County of Lancaster, Laundry Engineer, do hereby declare the nature of this
invention to be as follows:-
The invention relates to the gear employed for automatically reversing the
revolution of washing wringing mangling or other similar machines and can be so
arranged that the number of revolutions between each reversal can be varied as
desired.
The gear consists of simple worm and wheel gear or an arrangement of internal
toothed wheel similar to that described in the Specification of Patent No. 12981
of 1888 granted to Thomas Bradford, but instead of the arrangement of levers
therein employed for connecting the reversing motion to the strap-guides I employ
a small open frame lever of special construction in the open part of which works a
pin or stud which is attached to the toothed wheel and thus imparts to this framed
lever an oscillating motion.
This framed lever is provided with a slot or notch in the upper part for the
reception of a latch which is carried by a bar working in slides and connected to
the reversing rod of the strap guides.
I further so arrange this latch that when on one side of the rod it will fall into
the slot above mentioned and thus impart automatic reversing motion to the strap-
guides and it will when lifted over and allowed to fall on the other side of the rod
drop into a corresponding slot or notch attached to or formed in the frame of the
machine and thus hold the strap guides in any desired position for either stopping
the machine or working it in one direction.
When the latch is held upright the machine can be reversed by hand at the will
of the operator.

COMPLETE SPECIFICATION.
Improvements in Reversing Gear for Washing, Wringing, Mangling,
or other similar Machines.
I WILLIAM LITLER BRADFORD of The Crescent Iron Works Salford in the
County of Lancaster, Laundry Engineer, 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:-
The invention relates to the gear employed for automatically reversing the
revolution of washing wringing mangling or other similar machines, and can be so
arranged that the number of revolutions between each reversal can be varied as
desired.
The invention will be readily understood from the following description on
reference to the accompanying drawings.
Figs. 1 and 2 are respectively end and side elevations of so much of the driving
gear of a washing machine as is necessary to illustrate my invention.
The gear consists of simple worm wheel gear a a' as shewn or an arrangement
of internal toothed wheel similar to that described in the Specification of Patent
Price T

page_text: No. 12981 of 1888 granted to Thomas Bradford but instead of the arrangement
of levers therein employed for connecting the reversing motion to the strap-guides
I employ a small open frame lever 661 of special construction, in the open part 6 of
which, works a pin or stude which is attached to the toothed wheel a' and thus
imparts to this framed lever an oscillating motion.
This framed lever is provided with a slot or notch at X in the upper part b for
the reception of a latch d which is carried by a bar d' working in a slide or slides
and suitably connected to the reversing rod e of the strap-guides e'.
1 further so arrange this latch & that when on one side of the rod e (i.e. in the
position shewn in full lines on Fig. 1) it will fall into the slot X above mentioned
and thus impart automatic reversing motion to the strap guides e¹ and it will when
lifted over by means of the handle d² (or otherwise) and allowed to fall on the
other side of the rod e into the position shewn dotted on Fig. 1 drop into a corre-
sponding slot or notch attached to or formed in the frame of the machine as shewn
detached at fFig. 3 and thus hold the strap guides e¹ in any desired position for
either stopping the machine or working it in one direction.
When this latch is held upright as seen at Fig. 2 the machine can be reversed
by hand at the will of the operator.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The improved reversing gear for, washing wringing mangling and other
similar machines constructed and operating substantially as herein before described
and illustrated by the annexed drawings.
2. The combination with the strap guide rod of a sliding latch connected thereto
and so arranged that it can be disconnected from the automatic reversing lever and
moved by the attendant and locked to the fixed framing in any desired position
substantially as hereinbefore described.
Dated this 23rd day of August 1893.
