COMPLETE SPECIFICATION.
A New or Improved Appliance for Perambulators, Go-carts,
Bassinettes on Wheels and the like for imparting thereto an
Intermittent Backward and forward Motion.
We, JOHANN DUBIEL, Master Butcher, and LUDWIG HERRMANN Locksmith,
both of Zabrze, Upper Silesia, and LEONHARD URBANCZIK, Overseer, of Schwien-
tochlowitz, also in Upper Silesia, in the Empire of Germany, 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 a new or improved appliance for perambulators,
go-carts, bassinettes on wheels, and the like for imparting thereto an inter-
mittent backward and forward motion within a restricted space, such for instance
as in a nursery, hall, conservatory, or room where a child may be lulled to sleep
by movement of the carriage without, necessarily, motion being imparted to the
carriage by an attendant throughout the time.
The invention will be described in reference to the accompanying drawings
which illustrate its application in such wise that the same be carried into practical
effect.
Fig. 1, is a diagramatic side view indicative of the wheels and axles, and
springs and body-portion of a bassinette perambulator, but with the gear appliance,
and its parts of application, shown partly in section.
Fig. 2, is partial sectional side view of the rear wheel appliance, detached, and
upon enlarged scale, for showing more readily the detail of the parts.
Fig. 3,. is a plan view of the parts shown in Fig. 2, a, indicates the bearing
axle of the back wheels attached rigidly to the frame or springs; and b, the
front wheel axle arranged movably, as will be further described.
The wheels of the carriage run loose on the ends of the axle n; and, according
to the fitting shown, the front wheels are fixed on the axle b, and the axle is
movable in its bearings.
The mechanism of the to and from motion is contained in the box d, which
is secured to the frame in proximity to the axle a.
The said actuating mechanism is connected with the front axle b, by the crank
arm e, (or an eccentric) a connecting link-rod f, and a lever arm g, loosely
collared upon the axle b, but capable of being fixed by a spring pin (or a screw
button) such as h, so that the axle can be made to follow the motion of the
lever arm g.
In this wise the forward and backward motion appliance can be detached for
ordinary driving purposes, and the connection be made only when the restricted
action is required.
The proportions of the crank e, and the lever arm g, are taken in such wise
that the complete turn of the crank or eccentric e, will produce only a swinging
motion of the lever arm g, which imparts, therefore, only a partial motion of the
axle b, and of the wheels so restricting the motion of the carriage to a backward
and forward action.

page_text: Together with such construction and application of parts a motive power
device such as a spring and train of wheels is to be employed.
As shown in the drawings, d, is the boxing containing the clock work
mechanism.
On the axle i, is carried the spring barrel the ratchet wheel k, and the
driving pinion m.
The ratchet wheel k, can be set in motion by the spring ratchet lever, to
wind up the spring, which is attached at one end to the axle i, and the other end
to the spring-barrel 7. A controlling spring catch ', is shown engaging with
the ratchet wheel to prevent the undue running of the spring barrel after winding
as is well known for such purpose.
The driver pinion m., is connected with the nave of the spring barrel 7, and
gears with the spur wheel n, carrying on its nave the pinion o, both mounted on
the intermediate cross axle, said pinion o, being in gear with the spur wheel p,
fast on the cross axle of the crank e, to which the motion is imparted from
the spring barrel 7.
Along with the constuction of mechanism there is combined for putting the
said motion device in and out of action. A ratchet wheel g, is fixed fast on
the crank axle e', with which engages ratchet tooth r, which can be kept up
to ratchet wheel g, by means of a stand-rods, actuated conveniently from the
outside of the box d, as for instance by means of the handle t. So long as the
cog-tooth, engages with the ratchet wheel the mechanism will be held in
position but by pushing in the handle t, and rod s, the ratchet catch r, will be
liberated and be moved out of gear with the ratchet wheel by the finger
spring, thus leaving the mechanism free to operate following the force of the
spring barrel 7.
In this construction the rocking lever arm g, is placed on the front wheels
axle, but if necessary the connecting rod f, can be arranged so as to clutch
and act directly upon hub or upon the spokes of one of the front wheels.
In some cases a musical box can be used along with this mechanism and
driven off the spring barrel axle i, to accentuate the soothing or somnolent effect
upon the child or occupant of the carriage.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
-
1. In combination with the body of a perambulator, go-cart, or bassinette on
wheels, and a movable axle of one pair of wheels, the arm g, on the said axle b,
connected by the link rod f, with the crank arm e, of a train of gear, substantially
as and for the purpose specified.
2. In combination with a carriage on wheels having the loose axle b, rocking
lever arm g, fixing pin h, link rod f, and crank eccentric e, of the train of wheels
operated by the spring barrel 7, and the winding lever v, and ratchet wheel k,
of the axle i, constructed combined and operating as and for the purpose set
forth.
3. The combination with the driving train of wheels operating as set forth
the control ratchet q. spring catch "", and the locking rod s, as and for the
purpose specified.
