GRUPE, joiner, of 11 and 13 Fernroderstrasse, Hanover, and EMIL FRIEDRICH MÜLLER,
manufacturer, of 11, Fortunastrasse, Linden, near Hanover, in the Kingdom of
Prussia and German Empire, do hereby declare the nature of our said invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The invention described hereafter refers to a merry-go-round, the boats or carriages
of which are enabled to turn round a common axis and to move vertically, so
that by the combination of these movements the boats or carriages move on with a
spiral motion. The invention is illustrated by the accompanying drawings in
which
Figure 1-shows a longitudinal section of the merry-go-round.
Figure 2 shows a horizontal section of the same at the line A. B, Figure 1.
Figure 3 is a plan of the same.
Figures 4, 5 and 6 represent detailed parts of the merry-go-round, particularly
the column with the motive arrangements, namely, Figure 4 is a vertical section,
and Figures 5 and 6 are horizontal sections at the lines C. D and E. F respectively,
Figure 4.
The merry-go-round is constructed in the following manner.
The pedestal of the merry-go-round consists of two crossed beams a of about
300 millimetres square section and each of nine metres in length, resting in a cast-
iron socket c which holds them firm and which also carries the worm e. Motion is
transmitted to the worm e through the shaft and pulleys d from a steam engine or by
any other motive power such as by hand. The motion of the shaft d is transferred by
the worm e to the wheel (of steel) which carries the drawing chain g (of wrought-
iron, of a thickness of 33 millimetres).
By arranging the transmission of power through a screw worm e the mechanisın
brakes itself in all positions and can thus work without any brake or stop arrange-
ment. On the long beams a there are placed four principals or posts which rest in
cast-iron sockets on the pedestal beams and are held firmly therein. Each post is
supported by two staysk which are held at their ends in cast-iron shoes or sockets I

page_text: on the beams a forming the pedestal. Each main post stands isolated with its two
stays and bears at its upper end a socket m with attached arm n which latter is
firmly secured to the centre portion o. In addition to this, the fixed middle portion o
is further supported and tied to the main posts h by stays p.
In the middle fixed portion o the main shaft q moves on vertically and horizontally
arranged anti-friction steel bearing rollers o¹, o¹¹.
The shaft g bears at its top the sockets s carrying the outspreading arms t, the rope
sheaves, and at its upper part a shackle w to which the stays are attached for
supporting the arms t. The arms consist of two beams of wood of section 60 by
160 millimetres. They have at their outer ends sheaves for the ropes y, over which
either one or two ropes may run. The second rope when used would serve as a safety
or reserve rope. The rope (or ropes) y is or are fastened by a hook to a ring Z,
which carries the boats, in such a manner that each point of attachment
(designated 1) of the rope y is situated midway between two boats. The other end
of the rope y is attached to a head 2, common to the ropes y, which is arranged
in such a manner that it can be moved up and down and can be turned horizontally.
Part of this head 2 is a swivel-shackle-piece 4 which carries the end of the chain g.
By the use of guide pieces, running in the vertical U shaped iron frame 3, the
turning of the ropes y is not communicated to the drawing chain g and twisting
of these ropes is thus prevented. To counterbalance the weight of the boats or
carriages, and in this way to diminish the working strain, the head 2 is arranged
to form a counterweight. The boats rare suspended from the ring Z which is held
by the ropes y, to a path or railway for the arms t, a rail 5 is provided, on which run
the rollers 6 attached to the arms t.
The impetus to the boat carrying arms t, and consequently the rotation of the
boats, is communicated through a cog wheel into which the cog wheel 7 gears, by
a chain and chain wheel connection 8 from the shaft 9. The rail 5 rests on the
cornices and is supported in 12 places. By uniting the single boats to
the ring Z a breakage of one post can take place without any damage being
done to any of the boats, and the weight of the boats is evenly borne by the
ropes y.
both
According to the corresponding transmission or the corresponding motive power
applied, the boats will either be drawn up and down or moved in a circle, or
motions may be combined. By combining both motions the boats describe a course
similar to the worm of a screw.
The rotary motion of the boais r can take place independently of the vertical motion.
The revolving part of the merry-go-round is fixed before attaching the boats
independently of the winch and a brake is provided on the column.
In working the apparatus, the upward movement of the boats commences as soon
as the apparatus starts, thus a dragging or capsizing of the boats which would occur
if the boatst ouched the ground, cannot take place.
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 wo
clain is-
:-
First. A merry-go-round, the boats of which are suspended by ropes in such a
manner and carried by arms that they can be drawn up vertically by means of a
winch mechanism.
Second. A merry-go-round,, the boats, of which are carried by ropes running
from arms which are rotary on a framework in a horizontal direction, and in
which the ropes can be tightened by a winch mechanism in such, a manner
that, the boats are first drawn up vertically and then moved horizontally round a
common axis.
Third. A merry-go-round, the boats of which are carried in a rotary manner
horizontally round a common axis and suspended by means of ropes to a winch
mechanisin in such a manner that they take a spiral path upwards or downwards
through simultaneous rotation of the arms and operation of the winch.

Fourth. In a merry-go-round, the combination and arrangement of a block 2
provided with a swivel piece 4 and to which the ropes y and the chain g of the winch e
are attached in order to enable the boats being pulled up and down and being revolved
without the ropes turning round their axis
Fifth. In a merry-go-round, the combination and arrangement of the column
which moves on rollers horizontally and vertically arranged and which carries the
arms on the socket pieces and by means of the socket pieces carries the
sheaves which carry the ropes y and the arms t, as described and illustrated in
the drawings.
