AN IMPROVED CONSTRUCTION OF STAND OR CARRIAGE FOR ROCK BORING OB EXCAVATING MACHINES
Year: 1869

page_text: LETTERS PATENT to Frederick Bernard Doering, of Victoria Street, in
the City of Westminster, Civil Engineer, for the Invention of
"AN IMPROVED CONSTRUCTION OF STAND OR CARRIAGE FOR ROCK BORING OB
EXCAVATING MACHINES."
Sealed the 11th January 1870, and dated the 10th November 1869.
PROVISIONAL SPECIFICATION left by the said Frederick Bernard
Doering at the Office of the Commissioners of Patents, with his
Petition, on the 10th November 1869.
I, FREDERICK BERNARD DŒERING, of Victoria Street, in the City of
Westminster, Civil Engineer, do hereby declare the nature of the said
Invention for "AN IMPROVED CONSTRUCTION OF STAND OR CARRIAGE FOR ROCK
BORING OR EXCAVATING MACHINES," to be as follows:-
My Invention consists in constructing stands or carriages for rock
in such manner that there is a clear or

page_text: open space beneath the machine, so that the men can pass under the
machine and clear out the rubbish or débris without difficulty. The
necessity of keeping the machines idle for so long a period after blasting
as with the forms of stand hitherto employed is thus dispensed with, and
much time is thereby saved.
The manner in which my Invention may be carried into effect is as
follows: The stand or carriage is mounted upon (say) four wheels; the
two hind wheels have no direct connection. by axle bars or otherwise
with each other, neither have the two fore wheels, but each hind wheel
is connected to the fore wheel on the same side by a horizontal beam;
from the two horizontal beams angle iron or other bars or pillars are
carried up, and these latter bars support at a sufficient height
verse bar or block, which serves the double purpose of a stay or con-
nection between the two sides of the stand and of a support for the
boring engine or engines and parts connected therewith. The rails on
which the stand travels, which are borne by longitudinal sleepers or
otherwise, may be placed at such a height as to raise the stand or to
assist in raising the stand sufficiently to give room for men to pass
under the machine without difficulty for the purpose herein-before
explained.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederick Bernard.Doering in the Great Seal Patent
Office on the 10th May 1870.
TÓ ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
BERNARD DEERING, of Victoria Street, in the City of Westminster, Civil
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of November, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Frederick Bernard Doering, Her special
licence that I, the said Frederick Bernard Doering, my executors, admi-
nistrators, and assigns, or such others as I, the said Frederick Bernard
Doering, my executors, administrators, and assigns, should at any time

page_text: agree with, and no others, from time to time and at all times, thereafter
during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"AN IMPROVED CONSTRUCTION OF STAND OR CARRIAGE FOB. ROCK BORING OR
EXCAVATING MACHINES," upon the condition (amongst others) that I, the
said Frederick Bernard Doering, my executors or administrators, by ap
instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain, the nature of the said
Invention, and in what manner the same. was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months, next and immediately after the date of the said Letters
Patent..
NOW KNOW YE; that I, the said Frederick Bernard Doering, do hereby.
declare the nature of my said Invention, and in what manner the samo
is to be performed, to be particularly described, and ascertained in and
by the following statement thereof,, reference being had to the accom-
panying Drawings, that is to say,
My Invention consists in constructing stands or carriages for rock
boring or excavating machines in such manner that an arrangement of
sleeves or other parts for holding the boring engine in any. required
position or angle is supported on a horizontal beam at sufficient height
to leave a clear or open space beneath the machine, so that the men can
pass under it and clear out rubbish or débris without difficulty. The
necessity of keeping the machines idle for so long a period after blasting
as with the forms of stand hitherto employed is thus dispensed with, and
much time is thereby saved.
t
The manner in which my Invention may be carried into, effect is
represented in side elevation at Figure 1, and in front clevation at
Figure 2 of the accompanying Drawings, and is as follows:-The
stand or carriage is, mounted upon (say) four wheels QQ; the two
hind wheels have no direct connection by axle bars or otherwise with
each other, neither have the two fore wheels, but each bind wheel is
connected to the fore wheel on the same side by a horizontal beam R;
from the two horizontal beams angle iron or other bars or pillars S, S,
are carried up, and these latter bars have rigidly connected to them at a

what manner the same is to be performed, I declare that I claim,
constructing stands or carriages for rock boring or excavating machines.
substantially as herein-before described and shown in the accompanying
Drawings, that is to say, in such manner that an arrangement of sleeves
or other parts for holding the boring engine in any required position or
angle is supported upon a horizontal beam rigidly connected to the sides.

under the machine to remove rubbish or débris.
In witness whereof, I, the said Frederick Bernard Doering, have
hereunto set my hand and seal, this Sixth day of May One
thousand eight hundred and seventy.
