PROVISIONAL SPECIFICATION.
Improvements in Reversing Gear Applicable to Washing Machines
and for other Analogous Purposes.
I THOMAS BRADFORD of The Crescent Iron Works Salford in the County of
Lancaster Engineer, do hereby declare the nature of this invention to be as
follows:
This invention relates to that class of washing or other machine wherein a sliding
rod or bar is employed to move a strap fork or other device for reversing the revolution
of the driving shaft at certain intervals, the said sliding bar being actuated by a
weighted lever which is caused to rock from side to side on its fulcrum, and my
invention is designed to improve the gearing which moves this weighted lever.
Upon the driving shaft I mount a worm gearing with a worm wheel fixed or
cast on a long bush or sleeve mounted loosely on a fixed rod or spindle.
At the other end of this bush or sleeve is formed or fixed an excentric carrying
a toothed wheel mounted loosely thereon and prevented from revolving, by a slotted
lever or tail piece working on a fixed pin.
This toothed wheel gears with an internally toothed wheel, which is loose on the
rod or spindle above named. The internally toothed wheel therefore slowly revolves
on the said spindle as the excentric carries its toothed wheel round inside it and
fixed to the said internally toothed wheel is a pin, which actuates the weighted lever
before mentioned. The latter moves the reversing rod or bar, and, by bringing an
open or a crossed strap on to the driving pulley, or by other known means, reverses
the motion of the driving shaft, and the worm thereon, and thus the excentric and its
wheel is driven in the opposite direction, thereby slowly bringing the pin on the
aforesaid internally toothed wheel round on the other side of the said weighted
lever.

COMPLETE SPECIFICATION.
Improvements in Reversing Gear Applicable to Washing Machines
and for other Analogous Purposes.
I THOMAS BRADFORD of the Crescent Iron Works, Salford in the county of
Lancaster 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 :-
My invention relates to that class of washing or other machines wherein a sliding
rod or bar is employed to shift a strap fork or other device for reversing the
revolution of the driving shaft at certain intervals, the said sliding bar being actuated
by a weighted lever which is caused to rock from side to side on its fulcrum and my
invention is designed to improve the gearing which moves this weighted lever.
The nature of my invention and the manner in which the same is to be performed
or carried into practical effect will be readily understood on reference to the two
sheets of drawings hereunto annexed, and the following explanation thereof.
Fig. 1. on Sheet 1. of the drawings is a front elevation of the reversing gear and
part of the frame of a steam washing machine. Fig. 2 Sheet 2. is an end elevation
of the same and Fig. 3 is a detached view of a portion of the gear hereinafter more
particularly referred to.

page_text: a is part of the framing of the machine and 6 the main driving shaft, d the fast
driving pulley, and e the two loose pulleys.
Upon the driving, shaft is mounted a worm gearing with a
worm wheel g
fixed or cast on a long bush or sleeve h mounted loosely on a fixed rod or spindle i.
At the other end of this bush or sleeve his formed or fixed an excentric k (see
Fig. 3) carrying a toothed wheel mounted loosely thereon and prevented from
revolving by a slotted lever or tail piece m working on a fixed pin or upon a fixed
part or rail a of the frame.
This toothed wheel gears with an internally toothed wheel n which is loose on the
rod or spindle above named.
This internally toothed wheel n therefore slowly revolves on the said spindle as the
excentric carries the smaller toothed wheel / round inside it and fixed to the said
internally toothed wheel n is a pin or projection o which actuates the weighted
reversing lever p before mentioned."
The latter moves the reversing rod or bar and by bringing an open or a crossed
strap onto the driving pulley in the ordinary way, or by other known means
reverses the motion of the driving shaft and the worm thereon, and thus the
excentrick and its wheel is driven in the opposite direction thereby slowly bringing
the pin or projection o on the internally toothed wheel n round on the other side of
the said weighted lever.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
The novel combination and arrangement of reversing gear substantially as herein-
before described and illustrated by the drawings annexed and especially I claim the
combination with the worm gearing of the excentric carrying a toothed wheel and
lever or tail piece, the said toothed wheel working inside an internally toothed wheel
upon which is fixed the pin which actuates the weighted reversing lever.
