I, DAVID LIONEL SALOMONS, of Broomhill, in the County of Kent, Baronet,
do hereby declare the nature of my said invention for "IMPROVEMENTS IN THE
METHOD OF LUBRICATION OF COMMUTATORS AND OTHER REVOLVING ELECTRICAL
APPARATUS," to be as follows:-
16
My invention relates to the commutators or similar revolving parts of electrical
apparatus to which lubrication has hitherto been with difficulty applied, and it is
designed to effect such lubrication in a simple and effective manner.
My invention consists of a reservoir containing any suitable lubricant, fixed in
convenient proximity to the said revolving commutator or similar part.
At the bottom or other suitable part of the said reservoir, I provide an exit
through which I thread flannel, lamp cotton, or other similar fibrous material, by
which a steady flow of lubricant will be drawn by capillary attraction from the
said reservoir, and thus allowed to lubricate the surface of the said commutator or
other similar revolving part.
To regulate the flow of the lubricant through the said flannel or other fibrous
material I apply a compress, conveniently regulated by a set screw, by which any
desired pressure may be applied to the said fibrous material, thus checking or
regulating the supply of lubricant as may be desired.

I, DAVID LIONEL SALOMONS, of Broomhill, in the County of Kent, Baronet,
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 :-
My invention relates to the commutators or similar revolving parts of an
electrical apparatus to which lubrication has hitherto been with difficulty applied,
and it is designed to effect such lubrication in a simple and effective manner.
In order that my invention may be the better understood, I now proceed to
describe the same, in relation to the drawings hereunto annexed, reference being
had to the letters and figures marked thereon.
Figure 1 is a general view of my improved lubricator applied to the surface of a
commutator.
Figure 2 is a longitudinal section through the said lubricator.
Figure 3 is a longitudinal section through a modified form of such lubricator.
Figure 4 is a longitudinal section through a further modified form of such
lubricator.
Like letters refer to like parts in the different figures.
My device consists of a reservoir A, containing any suitable lubricant, and fixed
in convenient proximity to the revolving commutator B or other similar revolving
part of an electrical apparatus. I conveniently support the said lubricator A by a
bracket C attached to any part of the dynamo or other electrical apparatus, the
lubricator being secured by a double clip D, so as to be easily adjustable both in
position on the bracket, and in height with regard to the lubricator. I conduct
the lubricant from the interior of the reservoir A by means of the capillary
attraction of lamp cotton E or other similar fibrous material, down an exit pipe F,
which may be continued as a pipe to the part at which lubrication is required, as
in figure 4, or which may be conveniently widened into a flat nozzle G as in
figures 1, 2 and 3. The nozzle in the latter case is conveniently filled with a piece
of flannel, felt or other fibrous material, to distribute the flow of lubricant steadily
and uniformly.
In order to regulate the flow of the lubricant through the said lamp cotton,
flannel, or other fibrous material, I apply a compress, conveniently regulated by a
set screw, or any other manner, and which I carry out in several modified ways, by
which any desired pressure may be applied to the said fibrous material, thus
checking or regulating the supply of lubricant as may be desired.
In the device, as shown at figures 1 and 2 I apply a cone H, attached to a
screwed spindle K, provided with a thumb screw L, external to the reservoir. By
means of this thumb screw, the cone block H may be screwed down into the mouth
of the exit tube F, which is correspondingly coned to receive it, and any desired
pressure may be applied to the strands of lamp cotton or other fibrous material,
which will pass between the aforesaid cone plug H, and the cone mouth of the
exit tube.

page_text: In figure 3, I apply a thumb screw M to the lips of the nozzle G of the exit pipe,
which is constructed with sufficient spring to enable the thumb screw M to compress
the flannel between the exit lips of the nozzle.
In figure 4, I apply the compress in the shape of clamping jaws P operated by
set screws N to the strands of lamp cotton or other fibrous material, before it enters
the exit pipe F.
I may use a combination of any one or more of these methods of compress to
regulate the flow of the lubricant as may be desired, or it is obvious any known
controlled lubricator may be similarly applied to lubricate the commutator.
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 In an electro generating or electro motive apparatus, the combination with
the commutator of the said apparatus, of a lubricating device supported in proximity
to the said commutator, to effect any desired supply of lubricant thereto, substan-
tially as described.
2nd In such a lubricator, the construction of a regulating compress either in the
form of a cone screwed home on a seating, or of thumb nuts compressing the jaws
of the lubricant tube or operating independent clamps, or in any similar mechanical
manner, whereby the flannel, felt, lamp-cotton, or other fibrous material which
conducts the supply of lubricant by capillary attraction may be subjected to any
desired pressure to control and check the supply of lubricant as desired, substan-
tially as described.
