As illustrated in said drawings, A is an exterior, casing or shell of a washing
machine and A', the main shaft thereof, which passes through the shell and supports
a perforated oscillating cylinder (not shewn) arranged in a manner heretofore common
and well known. A² is a gear wheel attached to the shaft A¹, outside of the head of
the machine by which oscillatory movement is given to said shaft. B is a shaft
arranged parallel with the shaft A¹, mounted at one end in a bearing upon the head
of the machine A, and at its opposite end in a bearing b, upon the end of the
bracket B', which is attached to the head of the machine, in the manner illustrated.
Said shaft is provided at a point adjacent to the head of the machine, with a pinion B²,
shown in dotted lines in Fig. 2, which intermeshes with the gear wheel A³, upon the
shaft A. C is a fixed pulley attached to the shaft B, and C, C, are loose pulleys to
turn freely on said shaft at opposite sides of said fixed pulley (), and C3, C4, are
driving belts on said pulleys. Upon said shaft B, between the said fixed and loose
pulleys and the outer bearing b, is located a sleeve D¹, which is attached to the hub of
the loose pulley C2, and is provided with a worm D. It follows from this construction
that the said worm is driven by said loose pulley and in order that said worm shall be
constantly driven, even when the driving belt C, is driving the fixed pulley, said belt
is made a little wider than the other belt C³, so that the edge of the said belt C4, will
lap slightly over the pulley 03, and thus keep the same in motion at all times. The
sleeve D1, is conveniently connected with the hub of the loose pulley C2, by means of
a clutch connection d, as clearly shown in the drawings in Fig. 1.
Said worm D, intermeshes with a worm wheel E, located above the shaft D, with
its axis of rotation at right angles with the said shaft. Said worm wheel is mounted
upon a frame F (Fig. 6) which sustains the principle operative parts of the device.
Said frame F, carries a slide bar and belt shifting arms or loops thereon, which
engages the belts and to enable said frame to be moved or shifted in its angular
position to correspond with the location of the belts, it is pivotally sustained in such
manner that it may be adjusted in angular position by turning about the axis of the
shaft B. For this purpose said frame is provided with a socket F', (Figs. 1, 3 and 6)
adapted to fit over or embrace a tubular annular extension 6' for holding the frame F',
[Price 811

page_text: in a desired angular position. Said cylindric extension b¹, is conveniently fixed upon
or integral with the cap 62, of the said bearing b, in the manner clearly shewn in
Fig. 3. Said frame F, is provided at its upper part with two guide apertures f¹ fl
(Fig. 6) through which is inserted a horizontal sliding bar G, arranged parallel with
the shaft B. Said bar is provided, at its end adjacent to the fast and loose pulleys,
with oppositely extending arms G1, G2, at the outer ends of which are attached
adjustable loops g¹, g', which engage the driving belts C³, C. H is a can-plate which
is located adjacent to and parallel with the worm wheel E, and is supported by and
adapted to move horizontally with the slide bar G, and also has a shifting movement
upon the bar in a direction transverse to these latter. To secure this movement of the
said cam plate H, the latter is provided, at its upper part, with two horizontally
arranged plates or arms which engage the upper and lower sides of the slide
bar G, which latter is provided with a transverse guide slot g², adapted to receive one
of the arms h. Said cam plate is provided, on its face adjacent to the worm wheel,
with two opposite projections or ribs H', H', forming a cam surface h², h², arranged
at right angles to the face of the plate and adapted for engagement with a stud or
pin e,
which is secured in and projects from the face of the worm wheel E.
Said cam surfaces 1, 2, are arranged opposite each other and are at a greater
distance apart at their upper and lower ends than at their middle parts. This
construction enables the pin or stud e to act upon the cam surface with the
effect of moving the cam plate in the same manner when the stud is turned in
either direction the said pin operating upon the upper right hand cam surface
and the lower left hand cam surface; when the worm wheel is turned to the
right, and acting upon the upper left hand cam surface and the lower right hand cam
surface when said wheel is turned to the left. Said cam surfaces are adapted for
engagement with and disengagement from said pin or stud e, by a bodily movement
of the cam plate toward and from the worm wheel E; this movement being afforded
by the sliding of the cam plate laterally upon the slide bar G, as hereinbefore
described. Such bodily movement of the cam plate, therefore, enables the machine to
be stopped and started when desired; the releasing of the cam plate from the pin at
the time both belts are on the loose pulleys, obviously affecting the stoppage of the
machine. At the side margins of the cam plate exterior to said cam surfaces, said
cam plate is provided with two flat plates or wings H2, H2, which are flush with the
edges of the flanges H', H', and which by striking the end of the stud e, serve to
prevent the cam plate from being thrust toward the worm wheel E, when said stud
is outside of the said flanges.
I is a hand lever by which the cam plate is moved, said hand lever being pivotally
connected at its lower end with the frame F, by means of a swivelled oscillating stud i,
mounted on a lug F2, on the hub F1 (Fig. 6). Said swivel stud i is provided with
an apertured head or eye, through which is inserted a pivot pin ", by which the lower
end of the lever I, is connected with the said stud. Said lever 1, is provided at its
upper end with a handle I', and at a point between the handle and its lower end is
connected with the cam plate H, in such manner that when the said lever is swung
outwardly or inwardly upon the pivot i, the cam plate will be moved toward or from
the worm wheel E. The connecting device for this purpose herein shown, consists of
a stud 2, in the cam plate, connected at its upper end with the hand lever, by means
of a pivot pin 3, passing through the outer end of said stud and through a slotted
opening, in the hand lever. The said hand lever is shown as slotted to receive
the head or eye of the stud 2, the pivot pin 3, being inserted through the parts of
the lever at opposite sides of the said stud. For securing or locking the hand lever
in position, the same is provided with a detent J, pivotted at the upper end of the
lever, by means of a pivot j, located near the handle thereof, said detent being
arranged to extend horizontally over the top of the cam plate and having a down-
turned end or arm j¹, adapted to engage with the slide bar G. Said detent has an
upwardly extending arm or handle J, arranged in such position, that it may be easily
grasped by the hand at the same time of actuating the lever I. The down turned

page_text: end, of said detent J, is adapted to engage with the rear face or edge of the bar G,.
when the cam plate is interlocked with the stud e, to engage a hole 1, in the bar G,.
when said cam plate is in position remote from the worm wheel. The detent J, is
preferably thrown downwardly into position to engage the slide bar G, by means of a.
spring herein shewn as having the form of a spiral spring 3, located between the
upper end or handle J', of the lever I, and the handle J of the detent.
K is a lock plate or bar arranged horizontally adjacent to the upper end of the
lever I, and parallel with the slide bar G. Said plate K, is herein shewn as supported
by means of arms K', K', which are secured to the casting F, preferably at a point
over the guide apertures f¹, f¹, of said casting. Said plate K, is provided on its
inner edge with a central notch k, adapted for engagement by the lever I, when the
cam plate, is at the centre of its stroke and the belts are held on the two loose
pulleys. Said notch is made of such depth, or in other words its outer wall is so
located that, when the hand lever I, is brought fully into the notch, the detent J,.
will engage the hole 2, in the slide bar G. It follows from the construction that
the hand lever cannot be locked in its outward position, so as to hold the cam.
plate H, free from the stud e of the worm wheel, until the hand lever has fully
entered the said notch k. The main purpose of the said notch k, is to lock and.
hold the hand lever I, from being shifted in a direction to move the slide bar G, at
a time the belts are on the loose pulleys and the machine not running.
At either side of the notch k, said plate K is provided with two bearing surfaces.
or edges k, k, arranged parallel with the bar G, and located at such a distance from
said bar that, when the lever I, is swung outwardly from said bar, the cam plate H,.
will be free from the stud e, so that the said cam plate may be moved independently
of the stud. It follows that when the hand lever is thrown against either of the said
surfaces k¹, k¹, it may be moved along the same by hand for the purpose of shifting
the slide bar G, and the belts.
At the outer ends of the surfaces k², k³, are located shoulders k², k², arranged at.
such a distance from the central notch k, as to arrest the movement of the hand
lever I, before the said cam plate is shifted sidewise a distance sufficient to bring
its external side edges past the stud e. The parts or surfaces k³, of said plate K,
outside of said shoulders k², k, are located at such distance from the bar as to prevent.
said lever being thrown out far enough to disengage the cam plate H, from the
stud e. Owing to the presence of said surfaces k³, 3, therefore, the cam plate can
never be released froin the stud except when the hand lever is between the
shoulders k, k2, and it becomes necessary to throw the said hand lever inwardly a
distance sufficient to bring the said stud e, outside of or beyond its side margin.
Said surfaces k³, k³, therefore, constitute a safety device to prevent the cam plate
from being thrust inwardly when the stud e is outside of or beyond the flanges H¹, H²,
thereby preventing the breakage of the parts which might result in case the machine
were supported with the stop e outside of the cam plate.
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:
upon
1. The combination with the shaft to be driven, fast and loose pulleys thereon,.
and driving belts, of a belt shifting bar or arm engaging said belts, a frame
supporting said belt shifting bar, devices for actuating the bar mounted the
