PROVISIONAL SPECIFICATION.
Improvements in Spring Washers for Apparatus for Clipping or
Shearing Animals.
ALBERT MARTIN North Kent Works Charles Street, Plumstead, Kent, Horse
Clipper Manufacturer I do hereby declare the nature of this invention to be as
follows:-
In a Patent you granted me 23rd May 1890, No. 8078 in it was for improvements
in a book shape spring washer and now I wish a Patent granted to me for
improvements I have made in the washer as the one mentioned in Patent No. 8078,
had two flat surfaces the underside that bears on the cutter plate and also the top
part that the nut takes its pressure on when tightened down the nut would not take
its bearing centrally and would have the tendency of throwing the clipper off its
cut and also break the spring of the washer when tightening it down To obviate
this I bend the top part of the washer that the nut takes its bearing on I concave
this like an arch in the centre of it and bend the front part of it down so that when
you tighten it down the front part will take its bearing on the upper part of the
bottom surface so that it will take a much greater strain to break this washer and
also with the concave make the nut take its central bearing. I also form another
kind of spring washer this washer is formed an oval shape and the ends are
rounding and the washer is formed concave and this is to be placed on the top of an
oblong washer and this washer has two slots in it on the upper surface so that the
ends of the oval spring washer should fit in them to keep it in position and also give
it a central pressure caused by the nuts.

COUL DELE DI MOTIVATION.
Improvements in Spring Washers for Apparatus for Clipping or
Shearing Animals.
ALBERT MARTIN North Kent Works Charles Street Plumstead London S.E.
Horse Clipper Manufacturer 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 certain improvements in the construction of apparatus
for clipping horses and clipping or shearing other animals as shewn in No. 1 and
No. 2. attached drawings. The improvements consist in keeping the top or cutting
plate secured to the under comb plate by means of spring washers so adjusted and
arranged and applied so as to press the top cutting plate on to the lower plate
evenly securely and with an accurately determined and self maintained pressure
after once being adjusted by the bolts which are fixed in the bottom plate and
passed through the top plate so that the machine never requires any further
adjustment and cannot get off its cut until it requires sharpening. These washers
are constructed of steel or any other suitable material. To form these washers !
bind the steel nearly double so that the bottom part bears on the cutter plate and
the upper part I bend concave and the front part bent downward so that it can
take its pressure on the upper surface of the bottom part, by bending this in this
form the nut is able to take its bearing more central and when screwing the nut
Pin1

page_text: down it almost becomes impossible to break the spring as the front part of the
spring is bent down so as to take its pressure on the upper surface of the under part,
as I found with them being straight and not concave and not being bent down in
front that they got broken off from the back of the spring washer. These improve-
ments obviate this.
I also form an oval hole in the top part of the spring so as to allow the top of
the spring a free movement so that it can take its bearing more evenly without
binding as the under surface that takes its pressure on the top cutter plate would
not lay flat if the pins were not exactly upright if the hole was not a little larger in
the upper part of the spring as shown on drawing No. 7 reference "e," as it is only
the square hole in the under-surface that holds it in position.
This
In drawings No. 3 and No. 4, I also form another kind of spring washer.
washer is formed an oval shape and the ends are rounding and the washer is formed
concave and this washer can be used with an ordinary oblong washer and this
washer to have two slots in it to hold it in position and to keep the spring central
and with free oscilating movement having the hole in it oblong to allow the free
movement. I also apply this spring washer to another kind of clipper in place of
using the ordinary kind of washers in combination with the oval spring washers
I apply it to a cover plate that takes it pressure on the top cutter plate in place of
the washers I form this cover plate with slots in it so that these oval spring
washers can fit in them to hold them in position as shewn in drawings No. 5,
and No. 6, and the nuts will always take their pressure evenly and central by using
these universal spring washers, they will not have the tendency of allowing the
nuts to take their bearing unevenly which without using the spring washer the nuts
would bear unevenly if the pins should not be exactly upright the nuts would have
a tendency of throwing the machine off its cut.
The object of my invention is that the opperator that uses them or any
inexperienced hand can re-adjust them themselves, when they use this kind of
spring washer and tighten the nuts down so that they take their bearing on the
spring washer and when they can see the spring give a little the clipper is on its
cut and it is not required to be tightened down with such a great nicety as it would
be if there were no spring washers as there has always been a great difficulty when
there has been more than one bolt to tighten to get them all tightened down with
great accuracy, and I have had many clippers sent back on account of one bolt
being tightened and not the other, as the ordinary kind of solid washer requires
great skill in tightening them to get them both of the same pressure without being
too tight or too slack I find this difficulty myself in getting anyone to adjust the
clippers with the ordinary solid washer.
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 as follows.
1. First, I claim the form of making a spring the shape as drawn on clipper
No. 1, and No. 2, drawings that is with the top of the spring being concave and the
front part being bent so that it can take its pressure on the top part of the under
part to prevent it from breaking, and the nuts can take their bearing more central
on account of its being rounding, and also having the oblong hole in it to prevent
it from binding as shown in No. 7 drawing A, reference E.
2. Second claim shewn in No. 3 and 4, drawing. I claim the oval concave
washer bearing on its ends, and also forming the underwasher with two slots, and
also the oblong hole in the oval spring washer.
3. In drawings 5 and 6 I claim the 4, slots, so that I can apply the oval concave
spring washers for adjustment in combination with the nuts.
