page_text: I, ALEXANDER HENRY REED, of Suffolk House, Laurence Pountney Hill, Cannon
Street, in the County of Middlesex, 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:-
This invention relates to devices for imparting reverse motions to a shaft by means
of belts, and it consists in certain novel features of construction which are fully
pointed out in the following specification and claims, and illustrated in the accom-
panying drawings in which
Fig. 1 represents an end view of the device.
Fig. 2 is a side view.
Fig. 3 is a diagram showing the device in a position different from fig. 1.
Fig. 4 is a detailed view of a clutch which will be further described as this ·
specification progresses.
In the example illustrated in the drawing, the device is shown attached to a
cylindrical washing machine, but it is obvious that it may be applied to any machine
where such a mechanism is required.
In the drawing the letter A designates a frame or casing in which is journalled the
shaft a to which a rotary motion is to be imparted, first in one and then in the other

page_text: direction. A large gear wheel B is mounted on the shaft a and.
ke engages a smaller
gear wheel C on the driving shaft D. This shaft is journalled at c and d in a frame E
which rotates around the axis of the shaft a and can be adjusted in any position by
means of stud bolts e which project from the casing A and by screw bolis tapped
into said casing, both said stud bolts and screw bolts passing through the circular
slot g in said frame in which the shaft F carrying the cam his journalled at i and j.
On the shaft D, which is the driving shaft, are mounted three pulleys G H I, two
of which, G and I are loose while the third H is fast thereon. The pulleys G and H
are of equal width of face, say 24 inches, while the pulley I is somewhat wider, say
3 inches "face." Two belts J and K, the former say 24 inches wide, the latter
34 inches, connect these pulleys with the line shaft, the belt J being twisted, while the
belt K is straight, so that when the former is on the fast pulley II, the latter will be
on the loose pulley I, and the shaft D will be revolved in one direction, while when
the belt K is on the fast pulley, the shaft will be revolved in the other direction. In the
drawing fig. 2 the last described position of the belts is shown, and from this figure it
will be observed that the belt K is of such width, that even when completely covering
the pulley H, it will extend beyond said pulley and still act on the loose pulley I.
From this description and the drawing, it will be understood that the loose pulley I, is
continuously revolved by the belt K, even when the latter is on the fast pulley H.
On the shaft D is also loosely mounted a pinion K which may be connected to the hub
of the pulley by a clutch O (figs. 2 and 4), or it may be permanently fastened to
said pulley this pinion engages a gear wheel mounted loosely on a stud m pro-
jecting from the frame E; to this gear wheel is attached a pinion n which engages a
gear wheel mounted on the shaft F which carries the cam acting on the free ends
of two belt shifters L M pivoted to the frame E at p and, one of which acts on the
belt J while the other acts on the belt K, so that when the cam is revolved as above
described, it will cause the belts to be alternately carried on to the fast pulley H on
the shaft D and cause the latter to be rotated alternately first in one direction and then
in the other.
h
When the line shaft is directly over the pulleys G H I, the position of the frame E,
which as above described, carries the whole of the reversing gear, is as shown in fig. 1,
but when it is necessary to place the machine carrying the device either to one side or
the other of said shaft, it will be found necessary to turn the reversing gear to the
required angle, and for this purpose the whole device is mounted in the frame E, and
the latter is made adjustable in any position as described above, (see fig. 3).
When it is desired to run the driving shaft continuously in one direction, the
moveable sleeve a of the clutch which slides loosely on the hub of the loose pulley I,
but is compellel to turn with it by the feather key 6 on said hub is disengaged from
the head c of the clutch which is carried by the pinion K, by means of the handle d'
pivoted at e to a bracket" secured to the frame E. This operation will disengage
the reversing mechanism and the same will remain at rest, while the driving shaft. D
will be free to revolve in the direction imparted to it by the belt then on the fast
pulley H.
By reference to the drawing (fig. 2) it will be seen that the cam is of such a shape
that it will move first one belt shifter then the other, or in other words, that it will not
move both belt shifters simultaneously. This has two advantages, first it will permit
the main shaft to recover from any momentum caused by the motion of the same in
the one direction before it is subjected to the action of the belt which is to turn it
in the other-direction, as the belts will be both on the loose pulleys during the time
intervening between the motion of the two belt shifters. The other advantage is that
during this time, when both belts are on the loose pulleys, the clutch O.may be
disengaged thereby disengaging the reversing mechanism causing the belt shifters to
remain at rest and permitting the belts to remain on the loose pulleys which obviously
will cause the machine to which the device is attached, to stop.

page_text: Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be preformed, I declare that what I claim is :-
1. The combination with the driving shaft, the pulleys G H I mounted thereon, the
belt shifters L M and the reversing mechanism actuating said belt shifters, of the
adjustable rotating frame E carrying said driving shaft, belt shifters, and reversing
mechanism substantially as shown and described.
2. The combination with the driving shaft D the pulleys G H mounted thereon, the
belt shifters LM, the shaft F, the cam mounted on said shaft connections between said
shaft and the driving shaft D, and the clutch O, substantially as and for the purpose
described.
3. The combination of the driving shaft D having the pinion k, the pulleys GH
and I on the shaft, the stud m the gear wheel mounted on the stud and having the
attached pinion n, the shaft F having the gear wheel O, the cam on said latter shaft
and the belt shifters L and M engaging the cam, substantially as described.
