page_text: I, THOMAS WALKER of Tewkesbury in the County of Gloucester 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 that class of Merry-go-rounds or Roundabouts in which
there are Horses or other Animals or boats, and the invention has for its object the
device or mechanism for imparting or giving movements to the above named. The
advantage to my improved construction are as follows.
Around the chimney or pole I fix a bevel wheel and above which wheel is the ordi-
nary lantern wheel and the usual spur wheel running into same, which causes it to
revolve round the chimney or pole. To the lantern wheel is fixed the usual wood and
Iron work commonly called the cheese wheel, and into which the wood or iron poles go,
these are commonly called swifts to these swifts brackets or bearings will be fixed and
fastened, and running in these brackets or bearings will be the shafts turned and
fitted in the usual way, to the inner end of these shafts bevel pinion wheels will be
keyed on so that as the cheese wheel revolves round the chimney, and the large bevel
wheel being stationary, it will give the shafts a revolving motion. On these shafts I
place a series of cains which are keyed or fastened to the revolving shafts, in these
cams will be one or more grooves or pathways in These Grooves I place rollers
specially made so that the horses, animals, or boats may swing out by the centrifugal
force in and to these rollers clips, pins, or studs will be fitted, and on these I hang
the hollow or solid irons to carry the horses animals or boats, so that as the cams
revolve on the shafts they will give a direct vertical, or up and down motion to the
horses, animals, or boats as carried on these pipes or solid irons from which the
horses, animals, or boats is being suspended and hung by special joints at the bottom
to allow the horses animals or boats to rock backwards and forwards. In the said
cams I have another roller with pin and clip working in another groove or pathway
and above the one that carries the horses animals or Boats and on this said pin clip
and roller a pipe or bar is run down inside of the outer pipe in case pipes are used or
outside where bars are used that carries the horses animals or boats. This inside pipe

page_text: or rod has also a direct vertical up and down motion which said pipe or rod will give the
galloping or pitching motion to the horses animals or boats. Namely the inside pipe
being attached by levers and joints to the body of the horses animals or boats will give
the above motion these said joints and levers can be coupled to the tail cars or head of
the horses or animals so as to give an appearance of being alive.
To prevent the horses animals or boats swinging out unevenly by the centrifugal
force I fix a double ball joint to the carrying rod of the centre horse animal or boat
and from this double joint I have single joints and these are connected to the outer
and inner carrying rods that carries the horses animals or boats.
Where steam power is not used the same motion can be obtained by any other
power such as man or horses to turn the cheese wheel round the pole.
For lightness and portability I make the horses or animals of sheet iron steel or
other metal pressed to the required form.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is an elevation and a part section showing position and working of
Roundabouts.
Fig. 2 is a plan of the usual plan of fixing swifts to the cheese wheel.
Fig. 3 A A A on elevation shows brackets or bearings for carrying shafts.
B B B are the cams for giving direct vertical up and down motion to horses &c.
CCC are the stud pins and clips for carrying the rollers and cams and also
supports and carries the outside pipe.
DDD are the outside pipes or bars to which the horses animals or boats are
suspended.
EE E are the stud pins and clips for carrying rollers in cams and supporting inner
pipe or rod to impart the galloping motion.
F F F are the inside pipes or rods.
G is the shaft that imparts motion to cams.
Fig. 4 is an elevation of cam showing pathway.
G is shaft.
His pathway giving the galloping motion to horse animal or boat.
I is pathway giving a vertical up and down motion to horse.
Jis lever or joint in connection with rod F that gives the galloping motion to
head tail or other parts.
K is horse pressed from iron steel or other metal.
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
1st. For using a cam to give a direct up and down motion to the horses animals or
boats that are suspended and hung to the usual swifts. The cams and shafts being
made fast to the swifts so that when the swifts are taken out all cams and bearings
comes out with it so that it is easily fitted up or taken down.
2nd. For this cam to give a second or more motions for giving the horse or animal
a perfect galloping motion which is worked from a second or more pathways by a
roller and rod or pipe and fastened to the horse or animal by joints or levers.
3rd. For making the horses animals or boats out of sheet iron, steel, or any other
metal pressed to the required form for this purpose.
