A Revolving Table or Frame for Miners' Safety Lamps.
We, MATTHEW BARR BAIRD of 59 Waterloo Street, Glasgow, Engineer, and
THOMAS THOMSON, Manager of Eddlewood Colliery, Hamilton, Lanarkshire, do
hereby declare the nature of this invention to be as follows:-
This invention relates to a revolving lamp carrier or frame specially designed for
holding the safety lamps used in collieries.
In carrying out our invention we fit on a vertical shaft a series of circular
platforms or shelves composed of angle iron rings supporting shelves or surfaces on
which the lamps are placed. These angle iron rings are secured to the shaft by
means of radial bars preferably made of angle iron and also by means of vertical tie
bars or stays which at their upper ends are jointed to other stays connected to
the shaft.
Distance pieces are or may be fitted on the stays, between each platform.
The shaft at its lower end is fitted in a socket and at its upper end in a bearing.
The shaft is or may be revolved by means of bevel, chain, or band and pulley
gearing from a counter shaft driven by power or by hand.
By revolving the carrier the lamps are presented in succession so that they can be
quickly taken off and handed to the miners.
Dated this 1st day of June 1896.

We, MATTHEW BARR BAIRD of 59 Waterloo Street, Glasgow, Engineer, and
THOMAS THOMSON, Manager of Eddlewood Colliery, Hamilton, Lanarkshire, 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 a revolving lamp carrier or frame specially designed for
holding the safety lamps used in collieries.
And in order that our said invention may be properly understood we have
hereunto appended an explanatory sheet of drawings whereon:-
Fig. 1 is a sectional elevation of the lamp carrier or frame.
Fig. 2 is a plan (the stays e being removed).
Fig. 3 is a detail view to an enlarged scale.
Fig. 4 shows a slight modification.
In carrying out our invention we fit on a vertical shaft a a series of circular
platforms or shelves composed of angle iron rings b, 61, and, preferably, sheet metal
supporting surfaces c on which the lamps are placed. These angle iron rings b, b',
are secured to the shaft a by means of radial bars d preferably made of angle iron

page_text: and also by means of vertical tie bars or stays e which at their upper ends are
jointed to other stays connected to the shaft a by means of a collar g.
As shown in Fig. 3 tubular distance pieces h are fitted on the stays e between each
platform.
The shaft a at its lower end is fitted in a socket i and at its upper end in a
bearing j.
The carrier may be merely rotated by hand; or it may he revolved by chain
gearing; or band and pulley gearing k from a counter shaft driven by power or by
hand.
Fig. 4 shows a method of revolving the carrier by means of bevel gearing k¹ from
a counter shaft 1.
By revolving the carrier the lamps are presented in succession so that they may be
quickly taken off and handed to the miners.
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
consider novel and desire to claim is :-
1. A revolving carrier or frame for holding miners' lamps constructed substantially
