Year: 1861

page_text: LETTERS PATENT to George Ingram, of Old Street, in the County of
Middlesex, for the Invention of "IMPROVEMENTS IN TEAMS TO BE USED
IN CONNECTION WITH THE WHEELS OF CARRIAGES ON COMMON ROADS."
Sealed the 31st January 1862, and dated the 20th August 1861.
PROVISIONAL
SPECIFICATION left by the said George Ingram at the
Office of the Commissioners of Paienis, with his Petition, on the 20th
August 1861.
I, GEORGE INGRAM, of Old Street, in the County of Middlesex, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN TRAMS TO
BE USED IN CONNECTION WITH THE WHEELS OF CARRIAGES ON COMMON ROADS,"
to be as follows (that is to say):-
My Invention has reference to an improved endless tram, to be used in
connection with the ordinary wheels of carriages, so as to lessen the draught,
and enable the said carriages to travel with greater facility than hitherto on
common roads, or soft or uneven ground, and consists in forming an endless
tram through the medium of jointed link couplings channelled throughout on
the inner surfaces, in which the wheels take and are caused to run, guide and.
lead rollers being employed for directing and giving increased freedom to the
action of the said tram, when single running or driving wheels are employed.
and the said tram being applicable to a line or train of carriages, by causing

page_text: the first pair of wheels to be provided with a tram arranged as above described,
whilst the remainder thereof are to be furnished with a tram passing round
the peripheries, so as to form one continuous channel way round the same.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Ingram in the Great Seal Patent Office on the 19th
February 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, 1, GEORGE
INGRAM, of Old Street, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of August, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself. Her heirs and successors, give and grant unto me, the
said George Ingram. Her special licence that I, the said George Ingram,
my executors, administrators, and assigns, or such others as 1, the said George
Ingram, my executors, administrators, and assigns, should at any time
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 "IMPROVEMENTS IN
USED IN CONNECTION WITH THE WHEELS OF CARRIAGES ON COMMON ROADS,"
upon the condition (amongst others) that I, the said George Ingram, my
executors or administrators, by an 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.
TRAMS TO BE
NOW KNOW YE, that 1, the said George Ingram, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the fol
lowing statement and the Drawings therein referred to (that is to say):
My Invention has reference to an improved endless tram, to be used in
connection with the ordinary wheels of carriages, so as to lessen the draught
and enable the said carriages to travel with greater facility than hitherto o
common roads, or soft or uneven ground, and consists in forming an endles
tram through the medium of jointed link couplings, channelled throughou
on the inner surface, in which the wheels take and are caused to run; bear

page_text: ing guide rollers being employed for directing and giving increased freedom to
the action of the said tram, and the said tram being applicable to a line or
train of carriages by causing the first pair of wheels to be provided with a
tram arranged as above described, whilst the remainder thereof are to be
furnished with a tram passing round the peripheries so as to form one
continuous channel way round the same.
And in order that my said Invention may be more fully understood and
readily carried into effect, I now proceed to describe it by the aid of the
accompanying Drawings, reference being had to the letters and figures thereon
marked (that is to say):-
Fig. represents a side elevation of an omnibus showing the wheels
furnished or supplied with my improved endless tram; Fig. 2, a front view
of the lower portion thereof; Fig. 3. an enlarged side view of the endless
tram separately shown; Fig. 4, a top or plan view of the same; Fig. 5, an
underneath view; Fig. 6; a longitudinal vertical section, taken through the
dotted line in Fig. 4; Fig. 7, a side view of one of the link couplings, of
which the said endless tram is formed or composed; Fig. 8, a front view of
the same; Fig. 9, a back view; Fig. 10, a top or plan view; Fig. 11, an
underneath view; Fig. 12, a longitudinal vertical section taken through the
dotted line in Fig. 10; Fig. 13, a transverse vertical section through the
dotted line 1, 1, in Fig. 7; and Fig. 14, a corresponding view through the
line 2, 2. In each Figure, the same letters of reference denote similar
corresponding parts.
A, A, the omnibus; B, B, running wheels; C, C, endless tram, formed or
composed of a series of link couplings D, D; E, E, pin or pivot centres,
through the medium of which the said link couplings are united or jointed
together, so as to turn, and thereby communicate a flexible action to the
tram; F, F, spaces or openings in the said tram, for admitting of the turning
or folding action of the same; G, G, tongues or lateral prolongations of the
links; H, H, grooves or recesses in which the same are held and secured by
means of the said pins .or pivot centres; I, I, flange projections, forming the
channel J, J, for receiving the tyres or peripheries of the wheels; K, K,
bearing guide rollers supporting the tram, so as to adjust the action of the
same upon the road or otherwise, and thereby present a uniform traction
or tramway to the wheels; L, L, axles upon which the said bearing guide
rollers revolve; M, M, branch bearings supporting the same, held or secured
to the axletrees N, N.
In conclusion to the foregoing description. it may be here necessary to
note that my improved endless tram is applicable to the wheels of carriages

page_text: of all descriptions, whether for agricultural or other purposes, and that the
said bearing guide rollers may be furnished or connected with stays or tie rods
suitably arranged for strengthening the same, as also for enabling the said
rollers to be raised or lowered in any required position, or otherwise commu-
nicating motion to the same, as may be found necessary.
Having now described the nature of this my said Invention, and the manner
in which the same is to be performed, I would have it clearly understood that
I do not confine myself to the precise details herein-before described, as
the same may be varied without departing from the general principle of
these my said improvements, nor do I claim as of my Invention, the exclu-
sive use of the several parts herein-before mentioned and referred to, except
when the same are employed in and for the purposes of my said Invention,
which hereby declare to consist in the construction and arrangement
of a jointed endless tram provided with a channelled wheel way, in the
manner and for the purposes herein-before set forth and described.
In witness whereof, I, the said George Ingram, have hereunto set my
hand and seal, this First day of February, in the year of our Lord One
thousand eight hundred and sixty-two.
