Improvements appertaining to Belt Driving Mechanism applicable
for use in connection with Washing and other Machines.
I, HENRY CROFTS LONGSDON of the Firm of W. Summerscales and Sons
Limited of Keighley in the County of York, Laundry Engineers and Machine
Makers do hereby declare the nature of this invention to be as follows: —
That is to say It relates to improvements in mechanism for automatically
shifting the driving belts from the loose to the fast driving pulleys and vice versa,
of those machines (such as are used for washing clothes or others requiring a
reversal of their motions at regular fixed intervals), wherein two driving belts are
used, one for imparting or transmitting motion to the machine in one direction
and the other in the opposite direction; and consists of constructing the parts
forming the said improved mechanism so that they shall perform their functions
efficiently while they may be adjusted to operate the driving belts in whatever
direction these latter are brought into contact with the driving pulleys.
In carrying my invention into effect I make use of the well known arrangement
of driving pulleys wherein tue one through which motion is transmitted to the
machine is placed between two loose pulleys that carry their respective driving
belts as is well understood.
I further use the worm and wheel arrangement for transmitting motion from
one or other of the loose pulleys (the driving helt on which is never entirely
shifted from it) to the belt shifting parts, however in accordance with my inven-
tion I arrange the bearings which carry the worm wheel to be supported by the
spindle, stud or shaft about which the driving nulleys rotate, said bearings being
secured thereto by screws or otherwise so that they may be readily detached there-
from for readjustment as the positions or directions in which the driving belts
may approach their pulleys, may necessitate.
On the face of the worm wheel or of a plate secured thereto, I fix a crank pin
arranged to carry an antifriction pulley or bowl for operating a lever, formed as
hereinafter explained, which is pivotally mounted on another lever the fulcrum
stud or support of which is secured to the bearings supporting the worm wheel.
This latter lever forms the handle-lever by an appropriately shaped handle
being pivotally secured to it, this said handle being further arranged so that it
may be forced into a normal position by a spring mounted on the handle-lever, in
order that it may be made to engage with a notched holding piece at each
extremity of its movements, said holding piece being also formed on the bearings
carrying the worm-wheel as in fact is also the holder in which the belt guide is
made to slide.
The lever operated by the crank-pin above referred to, has one of its extending
ends formed so that when the handle lever is moved to the extent of its path in
one direction, its said extending end is brought into contact with an appropri-
ately shaped projecting part of the worm-wheel-bearing, by which it is made to
assume a position at about right angles to the shaft carrying the driving pulleys.
In this position, by its other extending end taking over a projecting pin in the

page_text: sliding-belt-guide such belt guide is brought into its central position and the
driving belts are on their respective loose pulleys and so the machine is at rest.
An opening is made in the lever operated by the crank-pin to allow said crank-
pin to continue in its circular path without imparting motion to said lever on its
being brought into the position last before described.
When the handle lever is moved to the extremity of its path in the other
direction to the one above referred to, the lever to be onerated by the crank-pin
is raised and is so brought into position for said crank-pin to engage with it,
by which means it is moved backward and forward at each revolution of said
crank-pin with the desired results.

I, HENRY CROFTS LONGSDON, of the firm of Messrs. W. Summerscales and Sons
Limited of Keighley in the County of York, Laundry Engineers and Machine
Makers 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 mechanism for automatically
shifting the driving belts from the loose to the fast driving pulleys and vice versa,
of those machines (such as are used for washing clothes or others requiring a
reversal of their motions at regular fixed intervals), wherein two driving belts are
used, one for imparting or transmitting motion to the machine in one direction
and the other in the opposite direction; and consists of constructing the parts
forming the said improved mechanism so that they shall perform their functions
efficiently while they may be adjusted to operate the driving belts in whatever
direction these latter are brought into contact with the driving pulleys.
The accompanying sheet of drawings is illustrative of my invention and in
this:-
Fig. 1 is a sectional elevation of a machine's driving mechanism with my
improved parts applied thereto.
Fig. 2 is a view of same parts as seen from above.
Fig. 3 is an end elevation of the parts shown by Figs. 1 and 2.
Fig. 4 is a similar view to Fig. 1 but shows certain of the parts in different
positions.
In carrying my invention into effect I make use of the well known arrange-
ment of driving pulleys wherein the one a, through which motion is transmitted
to the machine, is placed between two loose pulleys bc that carry their respective
driving belts as is well understood.
I further use the wheel d and worm e which latter is secured to the sleeve f
of the driving pulley b (the belt on which is never entirely shifted from it) for
the purpose of rotating the former so that by the crank pin g secured on the face
of said wheel d this latter may transmit motion to the belt shifting lever h,
however in accordance with my invention I arrange the bearings k which carry
the wheel d to be supported by the fixed spindle or stud m, secured to the frame-

page_text: work n, and about which stud m the driving pulleys a b c rotate, said bearings k
being secured thereto by screws (as at k¹) or otherwise so that they may be readily
detached therefrom for readjustment as the position or directions in which the
driving belts may approach their pulleys, may necessitate.
at
bearings k.
On the face of the wheel d or of a plate (as at d Fig. 4) secured thereto, I fix
a crank pin g (above referred to) arranged to carry an antifriction pulley g' for
operating the lever h (formed as hereinafter explained) which is pivotally mounted
on another lever p the fulcrum pin or stud 2 of which is secured to the
The lever p forms the handle-lever by an appropriately shaped handle q being
pivotally secured at o¹ to it, this said handle q being further arranged so that it
may be made to engage with a notch or made in the holding piece r at each
extremity of its movements, said holding piece being also formed on or secured
to the bearings k as in fact is also the holder s in which the belt guide s¹ is made
to slide.
The lever above referred to has its extending end h³ formed so that when the
handle lever p is moved to the extent of its path in one direction as that shown
by Fig. 4 its said extending end h³ is brought into contact with an appropriately
shaped projecting part of the bearings k, by which it is made to assume a
position at about right angles to the stud or shaft m. In this position (as shown
by Fig. 4), by its other end h³ taking over a projecting pin sa fixed to the sliding
belt guide s such belt guide s¹ is brought into its central position and the belts
passing through their respective guiding pieces 3 s4 secured thereon, are main-
tained or kept upon their respective loose pulleys b c (the pulley 6 rotating freely
on the stud m while the pulley c rotates loosely upon the sleeve t¹ of the toothed
driving wheel t through which latter motion is transmitted from or by the fast
pulley a which is also secured on the sleeve t¹, to the machine by said wheel t
gearing with the other well known gearing wheels on said machine) and so the
machine is at rest. An opening is made in the lever h to allow the crank pin g
and its pulley g to continue in its circular path without imparting motion to
said lever on its being brought into the position last before described and as
illustrated by Fig. 4.
When the handle lever is moved to the extremity of its path in the opposite
direction to the one above described, the lever h is raised (see Fig. 1) and is so
brought into position for the crank pin g and its bowl gi to engage with the
sides wow of the elongated part of the opening causing the lever h to oscillate
and so move the belt guide s¹ as desired.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. The several parts forming the improved belt shifting mechanism, the same
being constructed and arranged to operate in combination substantially as herein
specified.
2. In belt shifting mechanism of the kind described, bearings for the several
parts arranged to be adjustable about or upon a fixed shaft or stud substantially
3 specified.
3. In belt shifting mechanism the kind described, handle lever and the
oscillating lever mounted thereon, the same being formed and arranged to operate
substantially as herein set forth.
