Improvements in Apparatus for Treating the Human Body for the
Cure of Certain Diseases or Ailments.
I, CARL HARALD LIEDBECK, of Stockholm, Sweden, Motorpathist, 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 machine for imparting a vibrating or shaking motion
to some part of the body, for the purpose of effecting the cure of certain bodily
ailments.
The imparting of this motion by hand is subjected to a double restriction, partly
as to the time, because it is impossible to perform by hand a uniform shaking for a
longer time than about half a minute, and partly as to the speed, as the shaking or
vibrating by hand cannot be brought up to more than 700 to 800 a minute.
If therefore the shaking or vibrating motion is to be effected in the best possible
way this motion must be imparted by a machine.
All the machines heretofore used for this purpose are somewhat restricted in their
applications; they require great space and a considerable driving force and are
therefore not as popular as they should be.
According to the present invention the above mentioned inconveniences are
essentially removed and the advantage gained, that the vibrating motion may be
imparted to any desired part of the body without necessitating the whole body
occupying a certain position, which might be less favourable to the effect of the
said vibrating motion. The improved vibrating or shaking machine permits of the
body occupying that position which is most suitable for the treatment in each
particular case, in consequence of which that part of the body which is to be
subjected to treatment may at will be made more or less passive.
The improved machine consists of three principal parts the driving mechanism, the
vibrating or shaking apparatus and the parts of contact.
In the accompanying drawing -
Figure 1 shows the driving mechanism.
Figure 2 is a shaking or vibrating apparatus with the vibrating or shaking portion
in the same plan as and surrounding the excentric.
Figure 3 is a vibrating or shaking apparatus with the suspension shaft of the
vibrating portion below the excentric.
Figure 4 is a vibrating apparatus with the suspension shaft of the vibrating
portion above the excentric, and
Figure 5 is a vibrating or shaking apparatus disposed as that represented in
Figure 4, but with the excentric as well as the vibrating part located in the longi-
tudinal direction of the shaft in lieu of being perpendicular to the same.
The driving mechanism is supported by a frame a, in the lower part of which is
an attachment screw, by means of which it may be located at a suitable place for
instance at a table plate. At the top of the frame is arranged a horizontal shaft b
the free end of which supports a crank or fly-wheel e provided with a crank-handle.
On the shaft is fixed a toothed wheel d gearing with one or more driving wheels e
fixed on shaft e¹ running in the frame from which shafts the rotatory motion produced
by turning the crank handle may be transmitted to the vibrating apparatus held in
the hand, by means of flexible shafts, the one end of which is connected with the
driving shaft of a vibrating apparatus while the other end is connected with the
shaft e. By suitably arranging the proportion between the toothed and the driving
wheels, any desired speed may be imparted to the driving shaft and therefore to the

page_text: vibrating or shaking mechanisin which speed may moreover during the motion be
increased or diminished by modifying the speed at which the crank handlo is
turned.
The vibrating or shaking apparatus is entirely or partly enclosed in a handle
which is held in the hand when the motion is to be imparted. Through the handle
runs a driving shaft g enclo ed in a tube f, the one end of the said shaft being in
the manner aforesaid, connected with the driving mechanism. The other end of the
driving shaft supports an excentric h preferably triangular and fixed perpendicularly
to the shaft, which excentric when rotating produces the vibrating or shaking-motion
by reason of its working between two sliding surfaces on the vibrating portion thus
producing an oscillating notion of the said part.
The shaking part can either surround the excentric in the shape of a shell and
move in the same plane, in which case the extent of the motion will be equal to
double the throw of the excentric or the extent of motion can be made greater or
smaller than the throw of the excentric by adjusting the suspension shaft of the
shaking part at a suitable point in the handle above or below the excentric. If, on
the contrary the shaft of the vibrating or shaking portion is located perpendicular to
the handle, the arrangement rendered intelligible in Figure 5 is obtained.
The simplest form of the vibrating or shaking apparatus is represented in Figure 2,
where the excentric is enclosed between the two sliding surfaces of a capsule k, to
which at the rotation of the excentric an alternate motion is imparted on a subjacent
plane. The capsule is covered with a lid m with which the desired part for trans-
mitting the motion to the body is connected.
If it is desired, that the vibrating portion shall move around a shaft located below
the excentric, as shown in Figure 3, the capsule k is prolonged downwards and is, by
means of pivots connected at the bottom with the tube surrounding the vibrating
shaft. The top of the tube is then provided with a shoulder or collar g', which,
working between two guides arranged in the capsule, guides the vibrating part in its
oscillating motion. The capsule in this case is also covered with a lid in which any
desired contact piece may be arranged.
If, on the contrary, it is desired that the vibrating or shaking portion shall move
around a shaft located above the excentric, as shown in Figure 4, the end of the
tube, which is located under the excentric should be provided with an enlarged
screwed portion n constituting an attachment for the hollow handle, which consists
of two parts, which are screwed on from opposite sides. The said enlarged portion "
supports two arms y located on the respective sides of the excentric, which arins
sustain the suspension shaft of the shaking part constituting at the same time a guide
for the lower part of the vibrator surrounding the excentric, which part, in the
manner already describod is set in motion by the rotation of the excentric.
In the machine shown in Figure 5 the driving shaft g is perpendicular to the
handle, which encloses its one end, supporting the excentric . This is enclosed by
the lower frame shaped part of the vibrator, which is suspended on a shaft o and in
the manner above described connected with an arrangement r for supporting the part
of contact.
The vibrating portion can be connected with the parts of contact in such a way
that its top part, as indicated in Figure 4, is made hollow and screwed in the interior,
so that a pin may be screwed in the part of contact being fixed on its free end. By
means of this arrangement it is possible whilo the machine is in use and the contact
pressed against the body to change the length of the vibrating portion that is to say,
the extent of motion of the vibrating portion, by turning the machine handle so as to
screw the pin in or out. The parts of contact (Figure 4) may be shaped so as to
adapt it to the particular part of body, which is to be treated. They may thus be
disc-shaped cylindrical bowl-shaped, conical or forked or any other suitable shape and
have a handle, which according to the shape of the top part of the vibrator is arranged
so, that it may be pushed into or upon this, or be connected therewith in any other
way.

page_text: 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:-
A machine for the purpose above specified consisting of a handle, a driving shaft (g)
surrounded by the said handle and supporting an excentric (h) and a shell, fork or
frame () surrounding the said excentric and having at the inner side two parallel
planes between which the excentric is moved thus imparting to the shell, fork or
frame and the part of contact (r) connected therewith in any suitable manner, an
oscillating or shaking motion.
