Gauzes, Glasses, and other Parts of Miners' Safety Lamps.
1 ANDREW HOWAT of 6 Bellwood Terrace, Old Trafford, Manchester, in the County
of Lancaster Engineer, do hereby declare the nature of this Invention to be as
follows:-
The object of my Invention is to construct an improved apparatus or machine by
means of which the gauze cylinders the glasses and other parts of miners' safety
lamps can be more expeditiously and effectually brushed and cleaned than is possible
with the means or apparatus at present available.
To accomplish this object I mount say three spindles in bearings on a suitable
frame or bedplate and each spindle receives rotatory motion by means of pulleys and
a band or by gearing actuated by any convenient motive power. Let it be assumed
for the sake of example that the class of lamps which the machine is designed to clean
is that in which two gauze cylinders and a single glass is employed, then on one
end of each of two of the spindles and preferably on the same side of the machine I
secure two brushes of different diameters and of suitable lengths to correspond with
the internal diameters of the two gauze cylinders; below each of these rotary
brushes I pivot another brush and after the interior of each gauze cylinder has been
cleaned and while the cylinder is still upon the rotary brush the pivoted brush is by
means of its handle, raised into contact with and so brushes and cleans the outer sides
of the cylinder as it revolves upon the brush: I also pivot a small brush to the frame
opposite the end of each rotary brush so that by raising the small pivoted brush into
contact with the gauze end or top of the cylinder as it is revolving upon its rotary
brush the said end can be quickly and easily cleaned. The third rotary spindle can
either carry another brush adapted to clean a third size of gauze cylinder or the outer
metal shield or bonnet or the third spindle may carry any other suitable part which
would be of utility in the cleaning process.
The other ends of the three spindles on the other side of the machine carry
respectively on one spindle two circular brushes one large and one small the large

page_text: brush to clean the oil cup or reservoir and the screw thread cut thereon and the
small brush to clean the internal screw thread on the body or main portion of the
lamp flame; the next spindle carries a sleeve or equivalent part upon
which are
secured strips of linen or other suitable material for cleaning the inside of the glass
while the third spindle has secured upon it a cylinder around the interior of which
are also fixed strips of linen or like material which clean the exterior of the glass
when the latter is thrust into the interior of the cylinder as it revolves.
It is obvious that the details of the brushes and other parts may be varied as already
implied to suit different constructions of lamps and instead of three rotary spindles
four or even more could be employed if found necessary or advantageous.

I ANDREW HOWAT of 6 Bellwood Terrace Old Trafford Manchester in the County
of Lancaster Engineer, do hereby declare the nature of this Invention, and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
The object of my Invention is to construct an improved apparatus or machine by
means of which the gauze cylinders the glasses and other parts of miners' safety
lamps can be more expeditiously and effectually brushed and cleaned than is possible

brush the said end can be quickly and easily cleaned. The third rotary spindle can
either carry another brush adapted to clean a third size of gauze cylinder or the

which would be of utility in the cleaning process.
The other ends of the three spindles on the other side of the machine carry
respectively on one spindle two circular brushes one large and one small the large
brush to clean the oil cup or reservoir and the screw thread cut thereon and the
small brush to clean the internal screw thread on the hody or main portion of the lamp
frame; the next spindle carries a sleeve or equivalent part upon which are secured
strips of linen or other suitable material for cleaning the inside of the glass while the
third spindle has secured upon it a cylinder around the interior of which are also
fixed strips of linen or like material which clean the exterior of the glass when the
latter is thrust into the interior of the cylinder as it revolves.
It is obvious that the details of the brushes and other parts may be varied as
already implied to suit different constructions of lamps and instead of three rotary
spindles four or even more could be employed if found necessary or advantageous.

page_text: And in order that my Invention may be fully understood and readily carried into
effect I will describe the accompanying two Sheets of Drawings reference being had
to the figures and letters marked thereon.
Figure 1 is a plan of my improved apparatus or machine for brushing and cleaning
the gauzes glasses and other parts of miners' safety lamps.
Fig. 2 is an end view and Fig. 3 a side view of the same.
In these views. a designates the frame table or bedplate; 61 62 63 three spindles
mounted in suitable bearings c¹ c³ ³ and driven preferably by means of a single
band & passing over and under the three pulleys e e e carried respectively on the
spindles 61 63 63. To one end of the spindle 61 is screwed or otherwise secured a
brush fand to the corresponding end of the spindle is secured a similar brush fl
these brushes being preferably of different diameters to suit two sizes of gauzes.
Below the brushesff two brushes g g are pivoted on projections a¹ on the table a
and resting on the handles of these pivoted brushes is a button the spindle of which
passes through a hole in the table a and is secured on the other side by a nut
or equivalent not shown. By pressing down the button h the brushes 9.9¹ can
be raised simultaneously into the positions indicated by dotted lines Fig. 2 and as
soon as the button h is released the said brushes fall back into the positions shown in
full lines and their weight assisted by a spring i also raises the button again. At the
same end of the table as the brushes g g¹ is a rod ; which is supported in two
brackets a and is free to be turned on its axis by a handle j¹. On this rod j are
secured adjustably two brushes kk placed respectively opposite the ends of the
brushes ff. At the other end of the table there are two circular brushes a large
and a small one on a single spindle which is secured to the other end of the
spindle and secured to the corresponding ends of the spindles ³ are two buffs
or wipers m m³ the surfaces of which are made up of strips of linen chamois leather
or other suitable material. Below and between the two buffs m m¹ is a movable
pad n which is mounted on a spindle n¹ this spindle passes through a stationary
sleeve o and is pivoted to a lever n' which is pivoted to the table at a³ so that the
pad n can be raised or lowered at will by means of the lever n².
The operation of cleaning the parts of a miners' safety lamp with my improved
machines as follows:-
The spindles b¹³ ³ are set in motion by means of the band d and the interior of
the two gauze cylinders cleaned by means of the rotating brushes ff; when this
has been done the button his pressed to raise the brushes g gl as shown in dotted
lines Fig. 2 and clean the outer sides of the gauze cylinders and the handle j¹ turned
to raise the brushes k k¹ and clean the ends of the gauze cylinders while still upon
the rotating brushes ff. The screw on the oil reservoir is cleaned by means of the
circular brush and the internal screw in the lamp frame by the brush . The
interior of the glass or glasses is cleaned by the rotating buffs or wipers m m¹ and the
exterior by operating the lever n' and raising the pad n into contact with said glass
or glasses while on the revolving buff or buffs. I have found in practice that this
arrangement of the pad n for cleaning the exterior of the glasses is more convenient
that the cylinder lined internally with linen strips as hereinbefore described but I
wish it to be understood that such a cylinder may be employed if preferred. A shield
or screen such as a light metal plate might be placed between the brushes / l¹ and the
buff m in order to prevent any dirt flying from the brash on to the buff.
I bave not shown any part attached to one end of the spindle 62 but for lamps with
three gauze cylinders a third brush of suitable size and shape would be screwed on
and a corresponding brush fixed on the rod j and to clean the outer side of the gauze
either a loose brush could be employed as the gauze revolved with the rotating brush
or the arrangement and shape of the brushes gg' could be modified. Instead of
attaching another brush to the spindle 6 a drill or any other part might be secured
thereto or a brush suitably shaped for cleaning the chimneys of Mueseler and certain
other lamps.
Although I have shown and described three spindles I wish it to be clearly
understood that four or more spindles all carrying brushes buffs or equivalents and

page_text: driven by the band d may be employed if found advantageous or desirable. Again
the spindle may be omitted altogether and the spindles 6' 63 with the parts thereon
and the other parts used in combination substantially as shown and described.
In places where a large number of lamps are handled and cleaned two or more
machines might be employed the spindles of one having all the brushes and the
spindles of another carrying the buffs or wipers for the glasses.
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―
1.-The construction and combined arrangement of parts constituting an improved
apparatus or machine for cleaning the parts of miners' safety lamps substantially as
and for the purposes herein described and as shown.
2. The combination with the rotating brushes ff', of the movable brushes g gl
and kk severally or combined all arranged and operating substantially as herein
shown and described or in an equivalent manner, for the purposes specified.
3.-The combination with the buffs in m³ or one of them, of the movable pad n
substantially as and for the purposes described.
4. The arrangement of three or more spindles such as 61 62 63 carrying brushes
buffs or equivalents and pulleys all driven by a single band d as and for the purposes
described.
