Improvements in Electric Magnetic Massage Kneaders.
We, DAVID LICHTENSTADT, and CHARLES LICHTENSTADT, residing at
No. 689 Bloomingdale Road, in the City of Chicago, in the County of Cook
and State of Illinois, United States of America, Manufacturers, do hereby declare
the nature of this invention for IMPROVEMENTS IN ELECTRIC MAGNETIC
MASSAGE KNEADERS, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement, reference
being had to the accompanying drawings, in which :-
Figure 1 is a top or plan view; and
Figure 2 is a central longitudinal section.
The object of our invention is to provide an improved electric magnetic massage
kneader for use in all cases of nervous and rheumatic pains and in similar local
diseases. It is the chief object of our massage kneader to combine electricity and
magnetism with the massage treatment. Our invention consists in a kneader
provided with electric elements, which are adapted to be rolled over the surface
to be treated, and in the magnetic bar upon which said elements are supported, and
in the combination of the various parts as hereinafter described and pointed out in
the claims.
In the drawings :-
A, represents a frame of metal. Upon this frame of metal is secured an
insulated handle B. This handle B may be made of wood, glass, rubber or other
suitable insulating material.
C represents a magnetic steel bar which is secured in the frame A by means of
the nuts c. This steel bar C is a permanent magnet, and is highly magnetized
before being inserted in place.
D represents a series of electric elements. Each element D consists of a copper
disk d and a zinc disk e. Each disk has a central hole to fit the bar C loosely, and
is provided with a number of nipples g arranged around its periphery. The copper
disks d and the zinc disks e of each element are soldered together, and the outer
surface of each zinc disk is amalgamated with quick-silver in the usual way.
Between the several elements are placed felt pads f, which are saturated
preferably with diluted sulphuric acid and glycerine.
The elements are placed upon the bar C, which forms the axis, in consecutive
order, that is, first a copper and zinc element, then a prepared felt pad ; next a
copper and zinc element, and so on to the desired number of elements.
As many elements D may be used as may be desired or necessary in treating a
particular disease; as shown in Figure 2, six elements are used, which elements fill
the space between the ends of the frame A, but if desired to use a smaller number,
one or more elements may be omitted, and a rubber washer placed between the last
element and the end of the frame A. The number of elements may be greatly.
increased by increasing the size of the frame A, but the size shown is preferable
for many reasons.

page_text: The kneader is used by rolling the elements D over the surface to be treated,
and the electricity produced by the elements D and the felt pads will greatly
increase the efficiency of the kneader, as it is well known that the application of
electricity is a cure for rheumatism and similar diseases.
The magnetism of the bar C also greatly increases the efficiency of the kneader,
as magnetism also has been found efficacious in the treatment of rheumatism,
rheumatic pains and similar diseases.
The nipples g of each element are arranged so that the nipples upon one disk will
come between the nipples of the adjoining disk. By this construction, a nipple
will be in contact with the surface being treated at all times.
The handle B may be varied in form and size to suit the, convenience of the
operator. Where the person being treated desires to apply the kneader without
assistance, the handle B may be varied in form so that the person can readily apply
the kneader to the surface to be treated.
Having now particularly described and ascertained. the nature of our said..inven-
tion, and in what manner the same is to be performed; we declare that what
we claim is :-
1. In a massage kneader, the combination with a frame A and a bar C'of a series
of elements consisting of zinc and copper disks arranged upon said bar aud adapted
to be rolled over the surface to be treated, and felt pads f interposed between the
said elements, substantially as and for the purpose specified.
2. In a massage kneader, the combination with a frame A of a bar C permanently
magnetized, and rotating disks mounted upon said bar, substantially as and for the
purpose specified.
3. In a massage kneader, the combination with a frame A and bar C of electric
elements D consisting of copper disks d and zinc disks e, said disks being provided
with nipples 9 upon their periphery, and being adapted to be rolled over the
surface to be treated, and felt pads f, substantially as and for the purpose specified.
4. The combination with a frame A and a bar C permanently magnetized, of
electric elements D mounted upon said bar, and felt pads interposed between the
said elements, substantially as and for the purpose specified.
Dated this 27th day of January 1891.
