Specification Accepted, 23rd Sept., 1887.
I CHARLES EUSTACE HASELER, of 145 Hall Road, Handsworth Staffordshire
Mechanical Engineer, 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 the construction and arrangement of what are now known
as automatic candle shade holders, that is such holders which allow the shade to fall
from time to time and screen the flame as the candle burns down, and consists in
producing a more perfect automatic action, and which acts in an almost, if not quite,
imperceptible motion, the whole being attained in a much more simple manner than
heretofore.
Already candle shade holders have been made to act automatically, but subject to a
more or less intermittent motion, by reason of a rotating lever or finger, or by means
of a number of successive levers and the like, which act with an intermittent motion
that is, each lever supporting the shade holder, is freed when the said candle has
burnt so much more of its length, and allow the shade holder to fall through a further
measured distance where it is again held for a similar length of time when the process
is repeated.
In my invention however, the fall of the shade holder is constant, proceeding as the
candle burns, the mechanism of which is also simple and not liable to become
deranged.
In order to clearly describe this my invention and the manner in which it is to be
performed, I have appended bereunto an illustrative sheet of drawings, upon which
are figures and letters of reference, like letters referring throughout to the same
thing or part.
Fig. 1 is a view of a candle shade-holder constructed according to this my
invention.
Fig. 2 is a modification of detail of the same.
a represents the candle, 6 the upper part of a candlestick. Parallel to the candle I
provide a slide pillar c, which serves to carry the shade (in dotted lines) d shade
ringe &c. This pillar c may be fastened at its lower end to the candle by means of
a spring clamp for other device, or if preferred the said pillar may be secured in any
convenient manner to the candlestick b.

page_text: Attached to the shade ring e, by soldering, rivetting or otherwise I provide a
sliding bar g upon which are formed sliding bearings h, h, by turning the strip metal
forming the bar at right angles thereto and piercing therein a hole through which the
pillar c, passes and slides.
At the lower end of the sliding bar and in extension of
the lower bearing h, I form a finger i which is bent in a downward direction, and
which is brought to rest upon the upper end of the burning candle a.
By bending such finger downwards there is no liability for the melted wax &c., to
distribute itself on to the various parts, as is often the case where such fingers or
levers have an escapement motion imparted to them; thus it will be seen that the
candle supports the shade and its appendent mechanism from its upper transverse
surface.

In Fig. 2, I have illustrated a modification in the construction of the sliding bar
in which in order to reduce the friction of the sliding bearings I may provide rollers
which impinge against the edge of the pillar c. Instead also, of the sliding bearings h
being formed as in Fig. 1 1 may construct them of greater depth as in Fig. 2, but the
method shewn in Fig. I would be the simplest and cheapest.
In order to reduce as much as possible the shadow of the pillar c, from the flame of
the candle I should prefer to make the said pillar of a flat elliptical section as shewn
enlarged at k Fig. 1, nevertheless I may make such pillar of other sectional forms.
It will now be seen that, with this my invention continuously as the candle burns
away, the support is being removed from under the finger i, by reason of which the
sliding bar carrying the shade &c., is at the same time allowed to fall at a corresponding
rate.
-
Having now particularly described and ascertained the nature of this my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1st. The improvements in the construction and arrangement of automatic candle
shade holders as hereindescribed and illustrated upon the drawings that is to say :-
The supporting of the sliding bar, shade ring, and shade, or their equivalents by
means of a finger i, or its equivalent resting upon the upper surface of the candle,
substantially as and for the purposes specified.
2nd. The general combination and arrangement of parts constituting an automatic
candle shade holder, substantially as hereindescribed and illustrated in reference to
Fig. 1, and for the purposes set forth.
3rd. The modification of the sliding har g, having rollers j, as hereindescribed and
illustrated in Fig. 2, substantially as and for the purposes specified.
Dated this 18th day of August 1887.
