Improvements in Machinery or Apparatus for Oleaning Miners'
Safety Lamps.
We, WILLIAM ACKROYD, the younger, of Morley, near Leeds in the County
of York, Colliery Owner, and WILLIAM BEST of No. 9 Little Fountain Street,
Morley, aforesaid, Foreman Lampman, do hereby declare the nature of this
invention to be as follows:-
This invention relates to certain improvements in connection with machinery
and apparatus for cleaning safety lamps, and has for its object, the arrangement
of mechanism in such a manner that, the life of the brushes for cleaning the exterior
of the lamp "gauzes" and for supporting the same is greatly increased.
Hitherto the spindles for holding or supporting the lamp "gauzes" have been
secured rigidly to the frame of the machine and in close contact with the brush used
for cleaning the lamp "gauzes." When the machine is in motion the said brushes
are running idle for a considerable period, that is, without operating on the lamp
gauzes," at which time the brushes are subject to a greater amount of wear and
tear in consequence of their contact with each other.
By our improvement, we secure the small brush spindle to brackets mounted
to the frame of the machine and in such a manner that, when a lamp "gauze" is
placed thereon for the purpose of cleaning, the spindle is operated, by which the
small brush is brought in close contact with a larger circular brush, and upon the
gauze" being removed, the spindle is easily moved clear of the large rotating
brush, thereby greatly reducing the wear and tear of the brushes.

The machine is driven by preference, from a pulley secured to the spindle
carrying the "gauze" brush, the various other parts of the apparatus being driven
by frictional contact.

Morley, aforesaid, Foreman Lampman 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 connection with machinery and
apparatus for cleaning safety lamps, and has for its object, the arrangement of
mechanism in such a manner, that, the life of the brushes for cleaning the exterior
of the lamp "gauzes" and for supporting the same is greatly increased.
"
Hitherto the spindles for holding or supporting the lamp "gauzes" have been
secured rigidly to the frame of the machine and in close contact with the brush for
cleaning the lamp gauzes," so that when the machine is in motion, the said
brushes are necessarily running idle for a considerable portion of the time, that is,
without operating on the lamp "gauzes" by which the brushes are subjected to
a greater amount of wear and tear in consequence of their continued contact

page_text: with each other, than is the case when the apparatus is arranged according to our
invention.
In describing our invention in detail, reference is made to the accompanying
drawings, in which.
Fig. 1 represents a front elevation of a machine made according to our
invention, the hand wheel hereinafter referred to being removed for more clearly
showing the machine.
Fig. 2 is a side view, Fig. 3 a plan and Figs. 4 and 5 detailed modifications
hereafter referred to.
The frame supporting the working parts of the apparatus is indicated by the
letter A, and mounted thereto in suitable bearings is a shaft B, to which is
attached a circular brush C of large diameter, and on an extension of the said shaft
is another circular brush D of smaller diameter, both of which receive rotary
motion from the driving pulley E.
At each side of the circular brush C, we mount other brushes F. and F¹ upon
spindles G. and G' secured to the respective links H. and H' each supported by a
pin J. The bars K. and K' connect the sliding block L with the spindles G.
and G¹, the block being guided by the vertical spindle S, and kept in contact with
the cam M by spiral spring N, and when the said cam is in the position shown on
drawings, the brushes F. and F¹ are kept clear of the large circular brush C when
not required for cleaning lamp "gauzes," by which the wear and tear of the
brushes is reduced and a greater efficiency of the machine obtained.
"
The lamp "gauzes" to be cleaned are placed separately upon the brushes F.
and F, the cam M is then turned on its shaft by the operation of the hand wheel O,
the spiral spring N forcing the sliding block L down the spindle S towards the
base of the machine, thus moving the brushes F. and F' with the lamp "gauzes
thereon, towards and in contact with the rotating circular brush C, which by its
rotary motion cleans the exterior circumference and small openings through the
6f gauzes,"
"the brushes F. and F¹ being to some extent rotated by the frictional
contact of the brush C upon the " gauzes."
The brushes P. and P¹ may be used for a similar purpose, the brush P being
driven by friction disc Q rotated by the disc Q¹ secured on main driving shaft B.
The brush P¹ is mounted on a link H' supported by a pin J¹ and connected by
bar K² to the link H', so that by this compact arrangement, the apparatus is
capable of cleaning three " gauzes at the same time, and all three supporting
brushes moved clear of the rotating brushes C and P when not required or when
changing the "gauzes."
"
The interior circumference of the "gauzes" is cleaned by placing and holding
them on the rotating brush D. and the body and other portions of the lamp may be
cleaned by the face brushes R. R¹ and R', the former being driven by friction
disc Q and R' and R' by similar discs in contact with discs Q³ and Q
respectively.
The conical brush V may be used for cleaning such portions of the lamps as
cannot be operated upon by the other brushes.
The bars K. K and K and brushes in connection therewith may be operated
so as to bring the latter in contact with the rotating brushes C and P. by a modified
arrangement shown by Figs. 4 and 5, in which case the cam M is dispensed with
and the spiral spring N placed on the vertical spindle S₁ below the lever T.
supported at one end upon pin U. and provided at the opposite end with an
adjustable weight W.
Resting upon the lever T. is a sliding block L' somewhat similar to the block L,
before mentioned, and is caused to slide up and down the spindle S¹ by the
operation of the said lever, by which the brushes are moved towards or away from
the brushes C and P as required, thus by these means, the life of the rotating
brushes C and P and the supporting brushes F. F' and P' is greatly increased, by
being enabled to remove the supporting brushes away from the rotating brushes C
and P when not required for cleaning purposes.]

page_text: Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The combination of the rotating brushes C and P with the movable brushes F. F¹
and P¹ supported by links and operated substantially in the manner shown and as
hereinbefore set forth.
