SLIDE TUBE CANDLESTICKS, OF SILVER, SILVER PLATED, OR OTHER METAL, IN A MODE
MUCH MORE USEPULL, FIRM, AND SECURE, THAN ANY YET PRACTISED; within that
part of Great Brittain called England, the Dominion of Wales, and the
Town of Berwick-upon-Tweed, in such manner as to me, the said Samuel
Roberts, my executors, administrators, and assigns, should seem meet, and
that I, the said Samuel Roberts, my executors, administrators, and assigns,.

page_text: should and lawfully might have and enjoy the whole profit, benefit, commodity,
and advantage from time to time coniing, growing, accruing, and arising by
reason of the said Invention, for, and during the term of years therein mentioned;
to have, hold, exercise, and enjoy the said. licence;.power, priviledge, and advan-
tage therein granted or mentioned to be granted unto me, the said Samuel
Roberts, my executors, administrators, and assigns; for and during and unto the
full end and term of fourteen years from the dateof the said Letters Patent next
and immediately ensuing, and fully to be compleat and ended, according to the
Statute in such case made and provided; in which said Letters Patent is con-
tained a proviso, declaring that the same should be void unless I, the said
Samuel Roberts, should particularly describe and ascertain the nature of my
said Invention, and in what manner the same was to be performed, by an
instrument in writing under my hand and seal, and cause the same to be
inrolled in the High Court of Chancery within one calender month next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Samuel Roberts, in pursuance of the said
proviso, do hereby particularly describe and ascertain the nature of my
Invention to be as follows:-
1
The novelty and usefull part of this Invention consists in the fixing a rack or
number of notches upon one of the tubes which form the pillar of the candle-
stick, in which rack or notches a knob, or other projecting part, fixt to the
otlier tube of the pillar, is made to catch, by which means the sliding tube may
be suspended at any heighth within the receiving tube so firmly that no
moderate pressure apply'd to the top will be able to force it down without the
knob being provisionally turned out of the notch; the racks or notches as well'
as the knobs may be apply'd and fix'd in various ways and modes, all of which
it is unnecessary to enumerate; but the annex'd Drawings and references will
serve sufficiently to elucidate the whole.
Figure 1 is the external appearance of a candlestick drawn up to the full
length. A is the internal or sliding tube; C is the external or receiving tube,
continued down to the bottom in the inside of the foot D; B is a hoop, whichi
screws upon the top of the receiving tube C, and is lined with cloth or other
soft substance, to facilitate and steady the motion of the sliding tube A when
drawn up or down. Figure 2 is a section of the same candlestick, in which A
is the nozel hoop; B, the sliding tube; C, C, the hoop, lined with cloth or other
substance; D, D, the recieving tube; E, a hollow groove between two slips
the edge;
of brass or other metal, one of which, I, is indented or notched upon
the other, K, is streight and smooth, and both are soldered in the inside of the
receiving tube D, D; F, F, is the foot, soldered upon the receiving tube D, D,

page_text: at N, N; G is a square or oblong hole which perforates the bottom of the
sliding tube B; II is a metal spring, which, being inserted in the hole G, the
two ends of the spring (L and N) slide in the groove E, the end M against the
smooth side of the groove K, and the end L against the notched side I, and,
by lodging in one of the notches, stops the sliding tube B from descending any
lower, till by the sliding tube B being twisted a little, the ends of the spring Lis
drawn out of the notch; it will then slide either up or down the end of the spring
M, pressing against the smooth side of the groove K, till, being stopt at the desir'd
heighth, the elasticity of the spring I turns the sliding tube to its proper place,
and the end of the spring L again rests in one of the notches, and stops the.
farther descent of the sliding tube B; when drawn to the top, the ends of the
spring stop against the 'bottom of the hoop C, C, and prevent the sliding tube
B from being drawn quite out till the hoop C, C, is unscrew'd, when the spring
H, being taken out of the cavity G, the hoop C, C, may be drawn of the sliding
tube B. Figure 3 is the section of the working part of a sliding tube candle-
stick upon a different construction, in which A is the sliding tube; B, B, a
short hoop, lined with cloth or other soft substance, and screw'd into the end of
the outer tube F, F; E is a metal wire fasten'd in to the bottom end of the
sliding tube A; D, D, is a cork, perforated and slipt upon the wire C; e, e,
is a round piece of brass or other metal, perforated in the middle, and screw'd
upon the wire C, serving to compress the cork and keep it steady in its place;
G, G, is a tube of brass or other metal, going to the bottom of the foot and
nearly to the top of the outer tube, in which it is inserted; H is a hollow
groove cut through the tube G, G, one side of the groove being plain and the
other notched; I is a small knob of brass or other metal, solder'd or screw'd
to the outside, near the bottom end of the sliding tube A; when the sliding
tube A is drawn up or down, the cork D, D, slides within the tube G, G, and
the knob I within the groove II, and when the sliding tube A is twisted round
a little, serves to stop it for descending lower, by catching in one of the notches,
till, being again drawn out, by twisting the sliding tube A the contrary way, it
will again descend. Figure 4 is the section of the working part of a slide tube
candlestick, in which K is the sliding tube; L, L, a hoop of metal, lined with
cloth or other soft substance, and screw'd on the end of the receiving tube N, N ;
M is a ring of brass or other metal, as represented at P, screw'd into the
bottom of sliding tube K; O is a slip of brass, or other metal, plain on one
edge and indented or notched on the other, and soldered to the inside of the
recieving tube N, N, extending from the bottom to the hoop L, L; the ring
of brass M. has a notch cut on one side, as at Q, which receives the slip of
metal O. When the sliding tube K ist wisted, one side of the notch Q is turned

page_text: into one of the notches in the slip of metal O, and prevents the sliding tube
from descending lower till withdrawn by twisting the sliding tube K the con-
trary way. Tho' for the sake of perspicuity the above Drawings are represented
with only one sliding pillar, yet candlesticks may be made in the same manner
with any number of tubes, in which case the first or bottom sliding tube
becomes the receiving tube of the second sliding tube, and so on, to any
number.
In witness whereof, I, the said Samuel Roberts, have hereunto set my
hand and seal, this Thirteenth day of February, in the year of our Lord
One thousand seven hundred and ninety-eight.
Inrolled the Sixteenth day of February, in the year above written.
