Improvements in Motion Transmitting and Speed Changing
Mechanism.
I, VICTOR BELANGER, of 694, Massachusetts Avenue, in the City of Boston and
County of Suffolk, State of Massachusetts, United States of America, Gentleinan,
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 has relation to mechanical movements, and has for its object to
provide, first, novel and improved mechanism for transmitting movement from a
driving member to a driven member; second, new and improved mechanism for
changing the speed of the driven member at will without changing the speed of the
driving member.
..}
This invention is of great utility when embodied in the driving mechanism of
vehicles of various kinds, such as motor carriages, railway cars, bicycles, tricycles, etc.,
and especially when embodied in the driving mechanism of those vehicles in which
it is necessary or desirable to impart movement to the driven member from the
driving member at a greater or a reduced rate of speed, or to vary from time to time
the speed of the driven member; and accordingly the invention consists in a new
and useful mechanical movement, and the embodiment of the same in change speed
driving mechanism for vehicles. The invention likewise consists in certain features
of construction and arrangement as hereinafter set forth.
Reference is to be had to the accompanying drawings and to the letters and
figures marked thereon, forming a part of this specification, the same letters
designating the same parts or features, as the case may be, wherever they occur.

Fig. 18.
Fig. 21 represents a slightly modified form of the device shown in
Fig. 18.
Referring first, to Figs. 1 and 2, a indicates a rotary shaft to which power is applied
by any convenient means from a suitable source. Upon the said shaft is secured a
driving member which in this embodiment of the invention consists of a cylindrical
cup or shell a¹.. Within the shell is placed a cylindrical disk a² held eccentrically
therein by means of a series of graded rolls a³. These rolls are graded, or, in
other words, vary in diameter from large to small, and they are freely revoluble
about the axis of the driving member.
Projecting out from the center of the eccentric a² which I term in this embodiment
of the invention, a driven member, is a pin as having a trundle a extending into an
aperture in the crank a upon the end of a shaft as in axial alinement with the
shaft a. Power being applied to the driving member, its rotation will cause the
driven member to rotate at a slower rate of speed in the following manner.
The peripheries of the loosely mounted rolls frictionally engage the inner wall of
the cup or shell a' so that as the shell rotates they are caused to rotate on their own
axes and to roll or revolve about the axis of the driving member, and by reason of
their being graded, they operate in the nature of a wedge to cause the eccentric a
to revolve about the axis of the said driving member at a relatively slow rate of speed
and the motion of the said eccentric is imparted to the driven member as through
the medium of the pin as, as will be readily understood.
In Figs. 3 and 4, however, I have illustrated another embodiment of the invention
which is applicable for use on such vehicles as railway cars. In these figures,
b indicates an axle to the ends of which are secured wheels b¹ 61, the flanges of which
fit upon the rails. This axle is suitably journaled in bearings mounted on a truck b
in the well known way.
Rigidly secured to the truck is a bracket 63 provided with a sleeve 64, concentric
with the axle and through which the latter loosely passes.
Loose upon the said sleeve is a driving member 65 which in this embodiment of the
invention is an eccentrically arranged cup or shell having a hub 66 upon which may
be secured an armature 67 of any suitable electric motor 68 or to which power may be
transmitted from the motor in any desired way.
Between the inner walls of the shell and the external wall of the sleeve 64 is placed
a series of rolls 69 which are of different diameters or graded, and which may be
maintained in place in any desired way.
Projecting out from the rolls on each side of the largest roll are axially extending
pins 610 secured to arm 611 keyed or otherwise secured to the shaft or axle b. By
ineans of this form of the invention, power may be applied from the driving member
to the driven member having the arm 611 through the medium of the rolls b
which are caused to revolve about the sleeve b by reason of their frictional
engagement with the rotating driving member 63 which in this case is eccentrically
arranged.
It will be observed that I have stated the pins 610 extend into rollers on each
side of the largest roll. Now, as the driving member rotates, the largest roll
operates in the nature of a wedge to cause the said shell or driving member to revolve
about the axis of the axle and therefore the roll which follows it has more or less play
and is free to rotate. My reason, therefore, for employing the two pins and rollers one
on each side of the large roll is that there will be one roll which is free to rotate
and drive the axle irrespective of the direction of movement of the car.
'

page_text: I may here state that the hub of the driving member is loose upon the
sleeve b around which the rolls travel and it is supported entirely by the said rolls,
there being sufficient space between said hub and said sleeve to permit the said driving
member to revolve as an eccentric.
Next referring to Figs. 5 and 6, I have illustrated another step in the invention,
by means of which I am enabled to change the speed of the driven member without
changing the speed of the driving member.
In the drawings, c indicates a driven member which consists of a shaft mounted in
suitable bearings, and having on one end a sleeve c¹ rotatable thereon, and driven by
a belt wheel c². This sleeve is provided with an arm c³ secured thereto which is
slotted to receive a pin c* extending out from a cylindrical shell c³.
This cylindrical shell is eccentrically arranged with respect to the driven member,
and it is formed with interior bearing cones co co and with internally projecting
gear teeth c.
The grooved sleeve c³ is mounted loosely upon. the shaft c and
is provided with an outwardly projecting pin c which may be engaged by a
fork c¹º.
Between the eccentrically arranged shell and the sleeve c8 are placed balls c¹¹ of,
varying diameters which maintain the said shell in its eccentrical relationship with
respect to the driven member. Keyed to the shaft c is a pinion c2 in mesh with the
gear teeth on the eccentric shell. When the fork c¹ is withdrawn so that the bearing.
or sleeve c8 is no longer held against rotation, the rotation of the eccentric shell c
through the medium of the belt wheel c², the sleeve c¹, the arm c³ and the pin c²,
will cause the balls c, the said sleeve or bearing c8, the pinion c¹ and the shaft c to
all revolve in unison about the axis of the said shaft.
By engaging the pin c with the fork clo, and holding the bearing c8 stationary, the
rotation of the eccentric shell causes the balls to roll around the said bearing slowly,
and hence the revolution of the eccentric is retarded, although the rotation thereof is
not affected. This causes the teeth of the shell to successively engage the teeth of
the pinion, so that the said pinion is driven at the rate of speed of the sleeve c¹,
plus the speed acquired by the partial rotation given the said pinion by successively.
engaging the teeth c12 by the eccentric therewith. Therefore, in this instance, by
holding the bearing sleeve against movement, the revolutions of the eccentric and
the rotations of the driven member may be varied, without affecting the speed
of the driving member.
In Figs. 8 to 17, inclusive, I have illustrated a highly developed form of the
invention applied to the rear driving wheel of a bicycle. In Fig. 7, I have shown a
portion of the rear frame of a bicycle on which is supported the spindle d upon which
the hub d having a flange d¹ of the wheel rotates. The spindle is threaded on its
ends to receive two nuts d² d³, which are beveled on their inner faces to form bearing
cones.
In one end of the hub d¹ is forced or secured a ring d having a flange do between
which and the conical nut d² the anti-friction balls do are maintained. The ring d
is held against inward movement by a collar d' which is forced into the hub and
secured therein in any desired way.. A sleeve d is placed upon the spindle and its
beveled end d presses against the anti-friction balls do, as shown, its other end being.
enlarged or swelled to form a raceway for the anti-friction balls do which are placed
between it and the bearing cone d³.
A shell or bearing ring is placed in the enlarged end 12 of the sleeve d³, and is.
formed of very hard steel to withstand the wear of the anti-friction balls, so that the.
sleeve itself may be formed of relatively soft metal. Between its ends the hub is.
provided with an internal flange or ring d rigidly secured therein, and its.end
opposite the ring d is threaded to receive a bearing ring e. Upon the sleeve do, is
forced, or secured in any desired way, a bearing sleeve el having a flange e² to form a;
cone. Supported in anti-friction bearings upon this sleeve e is a cup-shaped sleeve es
having a hardened bearing ring e opposite the cone e, and between which and the
said cone are placed anti-friction balls e. The said cup-shaped sleeve e³ is externally.
threaded to receive a bearing cone 6, which is opposite the bearing, ring e, and

page_text: .
between the latter are placed anti-friction balls e. Upon the said threaded end of
the sleeve e³ is also screwed a sprocket wheel es which I term the driving member and
which is locked thereon by a lock nut e³.
The outer end of the said sleeve e³ is formed with a series of internal teeth or
otches 10 (see Fig. 12) to receive the inwardly projecting finger of a locking
clutch e¹ mounted in an internally grooved ring f rigidly secured upon the projecting
and enlarged end 12 of the sleeve 8. The said clutch has a pin or projection e¹²
projecting upwardly through an aperture in the said ring of the inwardly projecting
finger thereon being normally held in engagement with one of the notches in the
sleeve e by à leaf spring f¹ secured in the groove in said ring f.
The inner end of the sleeve e³ is formed with a flange, and the inner face thereof
is provided with a series of round or cylindrical apertures e¹³ equally disposed about
its axis, and at equal distances therefrom. Between the end of the said sleeve e³
and the said flange or ring d14 in the hub is a ring f2 arranged eccentrically with
regard to the hub and the spindle, and held in position by a series of anti-friction
rolls f³, all varying in diameter, and graded from large to small, as shown in Figure 9
one of the slowest of said rolls consisting of a coiled spring to hold the others in
proper relative position. The said eccentric ring f2 is provided with an inwardly
projecting flange f, from which pins project axially into the said apertures e¹³,
as shown in Fig. 10. A pin or stud f6 is secured in the ring or flange d¹, and
projects into an axial aperture in the largest one of the rolls, as shown in
Fig. 11.
A bearing cone or beveled sleeve d¹ is screwed upon the sleeve ds and is held in
place by a lock nut 16. The end of this cone or sleeve is arranged opposite to the
beveled end of the sleeve e and the ends of the rolls f3 are beveled so as to rest
against the said ends which thus constitute a bearing rigid with the sleeve d³, the
central parts of their peripheries pushing against the eccentric f².
Instead of the sleeve es being provided with cylindrical apertures e¹³, it may be
formed with radial grooves e¹, as shown in Figs. 15 and 16, to receive slides e¹5
secured upon the eccentric ring f. Under normal conditions, when the sleeve do is
locked to the sleeve e³, and power is transmitted to the sprocket es, the hub and the
eccentric ring f2 will rotate in unison about the spindle d. But upon depressing the
clutch e by any desired means, so as to unlock the sleeve d8 and the sleeve e³, and
by holding the ring stationary, the sprocket es and the sleeve e³ will rotate about
the sleeve do ou the anti-friction balls e5. As the said sleeve rotates, it rotates with
it the eccentric ring f, which in turn causes the rolls to roll around the sleeve d8 by
reason of its eccentric relationship, and since one of the rolls is journaled upon a
stud extending out from the internal flange or ring of the hub, the hub will be
rotated with the rolls. Inasmuch, however, as the rolls do not revolve about the
sleeve ds with the same speed that the eccentric ring 2 rotates, the speed at which
the hub is rotated is less than the speed of rotation of the sprocket wheel. The
ring operating in the nature of an eccentric, its speed of revolution about the
axis of the sleeve d³ is less than its speed of rotation about its own axis, its said
speed of revolution being equal to the speed of revolution of the rolls about the
axis of the sleeve d³.
Thus it will be seen that as long as the sleeve d³ is held stationary, the hub will
be driven at a lower rate of speed, and that as soon as the ring f is released and the
clutch el which connects the sleeve d8 with the sleeve is allowed to connect the
sleeve d³ and the sprocket wheel, the friction of the connecting parts will be sufficient
to cause the rolls, the eccentric, and the hub to all rotate in unison with the
sprocket wheel.
The movement of the eccentric is imparted to the hub in this form of the inven-
tion through the medium of the rolls, of which one is connected to the hub, but it
will be at once apparent that this might be accomplished in other ways.
For instance, in Fig. 17, the eccentric g is formed with external threads on which
are screwed two flanged rings g¹ g², the latter being provided with the pins e5 entering
the cylindrical aperture e¹s in the sleeve e³. The other ring g¹ is formed with a hub-

page_text: like flange, on which a nut g¹ is screwed to form a race-way for the anti-friction'
balls g, which are placed between the said hub and the flange or ring de projecting
inwardly from the hub. The aperture in the ring or flange is eccentric with respect
to the sleeve ds and is concentric with the eccentrically arranged ring g. When the
hub is constructed in this way and the sleeve d8 and sprocket wheel are connected,
the eccentric and the hub and the sprocket wheel all rotate in unison, but when the
sleeve and sprocket wheel e8 are disconnected, and the said sleeve d8 and the
bearings thereon are held stationary, the rotation of the sleeve e causes the rotation
of the eccentric ring and consequently its slow revolution about the axis of the
spindle, and the said bearing ring in revolving co-acts with the flange de in rotating
the hub at a relatively slow rate of speed.
In Figs. 12, 13 and 14, I have illustrated the form of means which I generally
prefer to employ for causing the operation of the clutch. The ring f is notched, as
at f, out through which the pin el projects. An arm g7 is secured on the spindle d
outside of the bicycle fork by a lock-nut 98, and projecting inward from the face of
the arm are guides gº go to receive the vertical slide g10 on the lower end of which
is a shoe gl adapted to enter the notch and depress the clutch e¹¹. A spring 12
is interposed between a pin 13 passed through the slide, and one of the guides g, to
hold the slide downward with the shoe in the notch. The rod is secured to the
upper end of the slide, and to a curved connection g15 which is pivoted upon a wrist
pin gl on a lever g17 fulcrumed on the bicycle frame below the seat. By throwing.
the lever forward, the slide is lifted out of engagement with the ring f and the
clutch, and by throwing it rearwards, the slide engages them again.
In Figs. 18 to 20, inclusive I have shown the device adapted for use in
connection with a hub having a sprocket wheel to which power is transmitted from
the driving cranks by a chain; but it will of course be understood that in lieu of
the sprocket wheel, I may employ a beveled gear wheel, or any other gearing that
may be desired.
In the said figures, a a indicate the rear forks of a bicycle in which is rigidly secured
the spindle h having the bearing cones h¹ h¹ which are threaded 'thereon so as to
be adjustable toward and from each other, and being locked against rotation under
normal conditions by lock nuts h² h² which bind the washers as and the ends of the
forks thereagainst.
i indicates a sleeve which is enlarged at one end and provided with a bearing ring i¹
between which and one of the cones h¹ are placed a series of anti-friction balls 22. The
opposite end of the sleeve is held in position by a series of anti-friction balls 23
which are held against the cone by a friction ring it inserted in a collar 5 having a
cone 1 and to be afterwards described. The enlarged end of the sleeve is externally,
threaded to receive the prime power or main driving sprocket wheel from which
power is applied from the crank shaft in any suitable or desired way, said sprocket
wheel being held thereon by means of a locking nut 28. When the said sprocket wheel
is revolved, it rotates with it the sleeve i. Intermediate of its ends, the said sleeve is
formed with external teeth constituting what may be termed a pinion or toothed
gear, there being also rigidly fitted upon the sleeve a bearing cone 11. The
enlarged end of the said sleeve is likewise formed into an inwardly projecting cone 110
all of these features just described being more clearly illustrated in Fig. 18.
The hubj of the rear wheel is threaded at one end to receive a ring to oppose the
cone on the collar 5, while into the other end of the hub is forced a bearing ring j2
to oppose the said cone 210, there being suitable anti-friction balls placed
between the cone and the ring j¹, and the cone and the ring j2 respectively, so
that the hub may rotate relatively to the sleeve i on anti-friction bearings.
The collar is provided with an internally threaded recess to receive the hub j³ of
a cup je which is substantially cylindrical and fits loosely within the hub j.
Secured in the cup is a hardened bearing ring between which and the bearing
cone before described, are placed anti-friction balls je so that the collar and the
cup jo are capable of revolving about the sleeve and the spindle h on anti-friction
i
.

page_text: bearings. The cup is internally threaded at its ends to receive a bearing consisting
of a hardened bushing or ring jº.
Between the bearing or ring 7 and the pinion or gear 10 formed on the sleeve i is
placed eccentrically a ring 10 which is preferably of hardened steel and which is
formed with internal teeth, as shown in Figs. 19 and 20, the ring being in engage-
ment with the said pinion at one point, as is clearly illustrated, the diameters
of the pitch-circles of the teeth of the ring and the pinion being substantially as
shown.
The toothed ring is held in its position by means of rolls j¹¹ of different diameters
to correspond to the varying distances between the periphery of the ring and the
internal wall of the ring .
The said ring 10 is secured to the bearing ring j2 before described by pins 12
inserted in the flange 13 and projecting into recesses or sockets 714 in the said bearing
ring 2.
Now it will be seen that the hub and its bearing rings j¹ j2 are secured to the
eccentrically arranged ring so that they will all rotate together although the said
toothed ring is not rigidly secured to the bearing ring j2 but is capable of a slight
movement relatively thereto; this being permitted by the enlarged sockets j¹ which
must be provided, as the toothed ring revolves on an axis parallel to and at a small
distance from the axis of revolution of the sleeve. i.
The collar before described, is formed in its periphery with a groove to receive a
strap-brake j15
The rotation of the sprocket wheel causes a corresponding rotation of the
sleeve i which, being locked into engagement with the internally toothed ring j
revolves the said ring about the axis of the spindle h, and through the medium of the
pins causes a corresponding rotation of the hub j, and the parts rotate about the
cones h¹¹.
The rotation of the sleeve in this event does not cause the movement of the.
internally toothed ring relatively to the pinion, as more friction would be
encountered in so doing than is required to revolve all of the parts about the cone
bearings h¹.
When it is desired to decrease the speed of the bicycle, the brake is drawn taut
and the cup jo being rigidly secured to the collar is held against rotation, and with
it is also held the hardened bearing ring j. Hence the revolution of the sprocket
wheel and the sleeve i causes the pinion to revolve the internally toothed ring 10
at a speed a little less than the rotation of the sprocket wheel and the rotation of the
toothed ring is imparted through the pins 12 to the bearing ring j2 and the hub j so
that the wheel travels at a slightly lower rate of speed than the sprocket wheel i7, but
with greatly increased power. The anti-friction balls and act to prevent any
material friction between the hub and the cones and 10.
In Fig. 21, I have illustrated a slightly modified form of my invention in which
the bearing ring k in the cup je is beveled to receive two sets of balls k¹ k¹, inserted
between it and the internally toothed eccentrically placed ring 10, which is in this
case provided with a threaded collar k² at its end opposite the flange . In other
respects, the construction is similar to that illustrated in Figs. 17 to 20.
It is evident that instead of the ring 1 being internally toothed it may be
externally toothed and intermesh with an internally toothed ring connected to the
bicycle hub, the graded balls or rolls in this instance being interposed between the
sleeve on the spindle and the ring 10 and the sprocket wheel being on a sleeve
loosely connected to the said eccentric ring 10.
One of the peculiarities of this embodiment of the invention, as above described,
in connection with Figs. 8-17 inclusive, is that the speed of the driven member, or
hub, is varied relatively to the speed of the driving member, or sprocket wheel,
without the aid of intermeshing gearing, and this I believe to be broadly novel. I
term the mechanism for transmitting motion from the driving member to the
driven member as "friction mechanism" and the eccentric ring as the "friction
eccentric" to distinguish it from the change speed devices in which one or more

page_text: tooth rings or eccentrics intermesh with concentrically arranged gearing for
transmitting power or motion.
The invention may be expressed in other constructions and the details thereof may
be changed or varied as required.
The rotary devices with the graded diameters (i.e. the rolls) have imparted to
them both a movement of revolution and a movement of rotation, and at times only
a movement of revolution, but they transmit their movement to the driven member,
in any case, in all of the embodiments of the invention hereinbefore described.
They are positively rotated at times, and in their revolution travel in a common path
about the axis of one of the members (driving or driven) which path is determined
by the surface of one of said members with which they engage. Hence the rolls
operate to impart a movement to the driven member, which may be the result of
their revolution, or the result of their revolution and rotation both.
By the foregoing description it is apparent in Figs. 5 to 21, I have provided a
driving member, a driven member, one of which is arranged eccentrically of the
other, and rotary devices having graded diameters inserted between said members,
whereby the said,devices transmit their movement of revolution or of rotation or both
of their movements to said driven members. For example, referring to Figs. 5 and
6, when the sleeve c8 is held stationary, the rotary devices or balls c¹¹ revolve and also
rotate around the axis of the shaft, and impart both movements to the driven
member but when the sleeve is free to rotate devices have a movement of revolution
only and do not rotate, so that said movement of rotation is imparted to the driven
member:
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A mechanical movement comprising a driving member, a driven member, one
of which is arranged eccentrically with relation to the other, and rotary devices having

to the other and an eccentric relation maintained between them.
4. A mechanical movement comprising a driving member, a driven member, an
eccentric for transmitting motion to said driven member, and anti-friction devices
