PROVISIONAL SPECIFICATION.
Improvements in Machines for Washing or Cleansing Clothes.
I, SAMUEL BARRETT of Laundry Machine Works, Hanover Street, Keighley
in the County of York, Laundry Eugincer, do hereby declare the nature of this
invention to be as follows, that is to say —
It relates to improvements in machines employed in the process of washing or
cleansing clothes and consists firstly of arranging and constructing the driving
and belt-guide mechanisms in such a manner that a reversion in the direction of
motion of the rotary dolly-head is automatically effected in a thoroughly efficient
manner. The second part of this invention consists of the method of constructing
said dolly-head whereby a better and more durable dolly-head is produced than
when the ordinary methods of construction are followed.
The first part of this invention is attained by making use of the well known
driving pulley arrangement consisting of two loose pulleys mounted upon the
machine's driving shaft, with a fast pulley mounted between them.
The bearings, carrying the shaft upon which these pulleys are mounted and
through which the dolly-head receives its rotary motion, I form to extend above
these pulleys and form suitable supports or guide pieces for the sliding bar carrying
the belt guides; antifriction rollers being mounted in said supports for said
sliding-bar to operate upon.
Mounted loosely upon this sliding-bar is an adjustable pendant bracket, that
reaches for connection with, so as to be operated by, a-crank-pin or a pin mounted
eccentrically on the face of a wheel rotated by a worm which is operated by one
of the loose pulleys in the manner well known.
Suitable means, as a handle-lever or a weighted catch lever, are employed for
coupling the pendant bracket rigidly to the sliding-bar whenever desired, so that
a reciprocating movement may be imparted by the pin in the worm-wheel to the
sliding-bar which in turn ships the belts as is well understood.
In order to effect this belt shipping operation to avoid unnecessary.delay
or waste of time in the operations of the dolly-head during the intervaliat
which the reversion of its movement is being performed, double inclines are
formed on the sliding-bar to operate upon the antifriction rollers above described,
by which means so soon as said bar is moved by the eccentrically mounted pin, for
its inclined edges to have passed over the centres of the antifriction rollers, the
remainder of the movement of said bar is effected by gravity causing same.to
operate quickly by its inclines slipping over the antifriction rollers so effecting
the shipping of the belt in a more desirable manner than heretofore.
To arrest the motion of the machine the coupling mechanism on the pendant
bracket is disengaged and the sliding-bar is held by having recesses formed
between each pair of its double inclines, for the reception of the antifriction
rollers, so that when said bar is moved into position for these recesses to be
over the centres of the rollers, it is prevented from being slided by gravity or
by the eccentric pin to put the machine into operation.
Provided that additional means for holding the sliding-bar in position are
required, the lever mechanism for joining the pendant bracket to the said sliding-
bar may be employed for holding said bar in said position when not joined or
coupled to the pendant bracket.
Respecting the second part of this invention I form the dolly-head by mounting
metal hubs, of appropriate shape, upon a shaft. These hubs are keyed or otherwise

page_text: rigidly fixed to the said shaft and if formed of iron they are preferably rendered
(by any of the well known processes) incorrodible.
The wings of the dolly-head are formed of the desired shape and their edges,
that are for contact with the shaft and hubs are formed so that when they are
all placed in position the shaft is entirely covered by them. The wings are
fastened to the hubs by screws that are made to pass edgewise through them,
having their heads embedded therein as a preventive of damage to the clothes
being cleansed.
By following this method of construction any of the wings may be detached for
repairs or to be displaced by a new one whenever desired, without any other part
of the machine being in any way interfered with.

COMPLETE SPECIFICATION.
Improvements in Machines for Washing or Cleansing Clothes.
I SAMUEL BARRETT of Laundry Machine Works Hanover Street, Keighley in
the County of York, 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, that is to say:
It relates to improvements in machines employed in the process of washing or
cleansing clothes and consists firstly of arranging and constructing the driving and
belt guide mechanisms in such a manner that a reversion in the direction of motion
of the rotary dolly-head is automatically effected in a thoroughly efficient manner.
The second part of this invention consists of the method of constructing said dolly-
head whereby a better and more durable dolly-head is produced than when the
ordinary methods of construction are followed.
Fig. 1 on the accompanying sheet of drawings, is illustrative, as side elevation,
of my improved belt-shifting mechanism.
Figs. 2 and 3 are end and top views of same.
Fig. 4 is side elevation shewing certain of the parts illustrated by Fig. 1 but in
different relative positions.
Fig. 5 is part sectional side view of my improved dolly-head.
Figs. 6 and 7 are detail drawings illustrative of the wing.
Figs. 8 and 9 are illustrations of the hub hereinafter described.
The object of the first part of this invention is attained by making use of the
well known driving pulley arrangement consisting of two loose pulleys a and a¹
mounted upon the machine's driving shaft b with a pulley c rigidly mounted upon
said shaft between said pulleys a and a¹..
The bearings d and d', which carry or support the shaft through which the
rotary motion of the dolly-head is imparted, are arranged to extend above these
pulleys a and a to form suitable supports or guide, pieces for the sliding bar e
which carries the belt guides and f Antifriction rollers and g¹ being mounted
+
y
in said supports for said bar e to operate upon.
Upon the sliding bar e and at his hinged a pendant that reaches for connection
with, so as to be operated by, a crank-pin (or a pin) & mounted eccentrically upon
the face of a wheel & rotated by the worm which is operated by the loose pulley a
by being mounted on a bush or sleeve attached to the hub of said pulley a and that
extends through the support d as is well understood.
The handle-lever m, hinged at m' to the part which hinges the pendant to the
bar e, is arranged to fit within the notch h formed in the extended end of the said

page_text: pendant h, so as to couple or join the pendant to the bar e in order that as the
pink is rotated a reciprocatory movement may be imparted to said bar e while by
the lever m being raised out of this notch as is shewn by Fig. 4, the rotary motion
of the pin simply oscillates the pendant and does not move the bar e. As will
be seen by the bar e being reciprocated the driving belts (not shewn) are alternately
moved from their respective loose pulleys on to the fast pulley c and so the
reversion in the direction of motion of the shaft b is effected.
In order to keep the pin & continuously in motion the rotary motion of the
pulley a when its belt is shifted on to the pulley c, is maintained by a certain
portion of its said driving belt being left to overlap same so that it never entirely
leaves it although it is shifted to impart motion to the pulley c.
To effect this belt shifting operation in such a manner as to avoid unnecessary
delay or waste of time in the operations of the dolly-head during the interval at
which the reversion of its movements is being performed, double inclines n n'
and n n³ are formed on the bar e, by which means as soon as the bar e is moved,
by the pin, for its inclined edges n and ³ or n¹ and n³ to have passed over the
centres of the rollers 9 and g¹, the remainder of the movement of the said bar e is
effected by gravity causing same to operate quickly by its inclines slipping or
sliding over the rollers g and g¹ thus effecting the shifting of the belt in a most
desirable manner.
To arrest the motion of the machine the lever m is raised as above described and
the lever p lowered so that its notch may lay hold of the projecting part pl fixed to.
the bare by which means said bar e is firmly held, its position when thus held
being arranged so that it will hold the driving belts on their respective pulleys a
and a¹.
To prevent the lever p from laying hold of its part pl or of the lever m during
the time or when said lever m is within the notch 2, a shield m² is attached to said
lever m over and upon which the lever p would slide and rest while it would be
prevented from laying hold thereof.
Respecting the second part of my invention I form the dolly-head by mounting
metal hubs "", of the shape shewn by Figs. 8 and 9, upon a shaft s. These hubs 1
are keyed or otherwise rigidly fixed to the said shafts and if formed of iron they
are preferably rendered (by any of the well known processes) incorrodible.
The wings t of the dolly-head are formed of the desired shape and their edges
that are for contact with the shafts and hubs are formed so that when they are
all placed in position the shafts is entirely covered by them. The wings t are
fastened to the hubs by screws (see Fig. 5, w) that are made to pass edgewise
through them, having their heads embedded therein so that they may not damage
the clothes being cleansed.
By following this method of construction any of the wings t may be detached for
repairs or to be displaced by a new one whenever desired, without any other part
of the machine being in any way interfered with.
Having now particularly described and ascertained the nature of my said inveu-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. The combination and arrangement of parts forming belt shifting mechanism
substantially as herein set forth, each and all of said parts being formed and
constructed to attain the object desired, as specified.
2. In belt shifting mechanism the combination of the sliding bar e having inclines
formed on it as set forth, with the pendant h, the same being formed and arranged
to operate substantially as specified.
3. In the construction of a dolly-head, the employment of hubs formed to be
attached to a shaft, and wings constructed or shaped for attachment to these hubs
substantially as specified.
4. The combination of the bar e formed as shewn, the pendant h, the lever m

page_text: having a cover m² and the lever p all these parts being arranged to operate
substantially as specified.
