Year: 1870

page_text: LETTERS PATENT to George Toolcy Tietjen, of No. 13, Carlton Road,
Kentish Town, in the County of Middlesex, for the Invention of
"AN IMPROVED METHOD OF ADJUSTING THE BODIES AND SHAFTS OR POLES OF
VEHICLES TO SUIT THE HEIGHT OF THE ANIMALS EMPLOYED TO DRAW THEM."
"
Sealed the 29th July 1870, and dated the 7th February 1870.
PROVISIONAL SPECIFICATION left by the said George Tooley Tietjen at
the Office of the Commissioners of Patents, with his Petition, on
the 7th February 1870.
I, GEORGE TOOLEY TIETJEN, of No. 13, Carlton Road, Kentish Town,
in the County of Middlesex, do hereby declare the nature of the said
Invention for "An IMPROVED METHOD OF ADJUSTING THE BODIES AND SHAFTS OR
POLES OF VEHICLES TO SUIT THE HEIGHT OF THE ANIMALS EMPLOYED TO DRAW
THEM," to be as follows:-
This Invention is designed to obviate the necessity of providing
separate vehicles to suite draught animals of different heights, and to
render vehicles readily adjustable to the varying heights of the animals
it may be from time to time desired to employ to draw them.

For these purposes I attach a plate with suitable holes to the upper
part of each spring, and instead of fixing the axle or axles to the bottom
plates or blocks of the springs I attach cach spring to a bottom plate
formed with or secured to a suitable bar. The upper plates are secured
to the bar or frame which carries the shafts or pole of the vehicle. The
improved bottom plate of each spring is formed with a hole, through
which is passed the lower. or plain portion of a swivel pointed screw
held in position by a collar and a nut, or washer and pin, so that the
screw can turn in the plate but is incapable of endwise movement
relatively thereto. This screw is formed with a part suited to receive
a key or, spanner, or other well known contrivance for causing it to turn
on its axis when requisite. Each end of the axle at the part corre-
sponding to the position of the screw is formed with a hole tapped or
screwed to receive the same, so that the turning of the screw shall cause
the improved upper plate and--bar of frame with the-shafts-or-pole and
body of the vehicle to approach nearer to or recede from the axlo so as
to correspondingly raise or lower the shafts or pole as the height of the
animal to be employed may require. Suitablo guide rods are provided
for guiding the axle as it is moved up and down. In order to allow the
springs to act without impediment these guide rods as well as the screw
are attached only to one plate--or part of their. spring.and: pass freely
through the other plate or part thereof.

In vehicles having four wheels of course the framing for carrying the
shafts or pole is dispensed with in the case of the back springs and
axle. In other respects the arrangement will resemble that already
described.
My method of adjusting the bodies and shafts or poles of vehicles to
suit animals of various heights by the application of plates, screws, and
guide bars in combination may obviously be modified to suit the require-
ments of particular cases.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Tooley Tietjen in the Great Seal Patent
Office on the 6th August 1870.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
TOOLEY TIETJEN, of No. 13, Carlton Road, Kentish Town, in the County 3
of Middlesex, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of February; in the year of
our Lord One thousand eight hundred and seventy, in the thirty-fourth
year of Her reign, did for Herself, Her heirs and successors, give-and
grant unto me, the said George Tooley Tietjen, Her special licence that
I, the said George Tooley Tietjen, my executors, 'administrators, and
assigns, or such others as I, the said George Tooley Tietjen, my exe-
cutors, 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 "AN IMPROVED
METHOD OF ADJUSTING THE BODIES AND SHAFTS OR POLES OF VEHICLES TO SUIT
THE HEIGHT OF THE ANIMALS EMPLOYED TO DRAW THEM," upon the condition
3 (amongst others) that I, the said George Tooley Tietjen, 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.

NOW KNOW YE, that I, the said George Tooley Tietjen, 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 following statement and accompanying Sheet of Drawings:
This Invention is designed to obviate the necessity of providing
seperate vehicles to suit draught animals of different heiglits; and to
render vehicles readily adjustable to the varying heights of the animals.
it may be from time to time desired to employe to draw them.
For these purposes instead of fixing the axle or axles to the bottom
plates or blocks of the spring, I attach each spring to a suitable bar or
frame which carries the shafts or pole of the vehicle. The extreme ends.
of the said bar are formed with holes, through which are passed the lower
or plain portions of swivel pointed serews held in position by collars and
nuts, or washers and pins, so that the screws can turn in the bar, but
are incapable of' endwise movement relatively thereto. In those cases
where nuts and pins are used the nuts are formed with a part-to-receivo-

page_text: a key or spanner or other well known contrivance for causing the screws
to turn on their axis when requisite, and in other cases where washers
and pins may be used the end of the screws are formed to receive the
key or spanner. The axle or axles at the parts corresponding to the
position of the screw is formed with a holo tapped or screwed to receive
the same, so that the turning of the screw shall cause the shafts or
pole and body of the vehicle to approach nearer to or recede from
the axle so as to correspondingly raise or lower the shafts or polc as
the height of the animal to be employed may require. Suitable guide
rods are provided for guiding the axle as it is moved up and down
by the before-mentioned screw. In order to allow the springs to act
without impediment these guide rods as well as the screw are attached
only to the improved bar or frame, and pass freely through the embossed
part of the axle and also through the guide plate which is attached to
the body of vehicle or other convenient position.
Fig. 1 represents an end view of my improved adjustable arrange-
ment for one side of a vehicle; Fig. 2 represents a side view of same.
The letters of reference are used to denote corresponding parts in both
Figures. A being the axle; B, the improved bar or frame which carries
the shafts or pole of the vehicle; C, the swivel ended screw; d, the collar;
e, the nut; e', the part formed for the key or spanner; f, the pin to secure
it in position; D, D, are the guide rods which move freely through the
embossed part E, E, of the axle, and also through the guide plate F,
which is shown broken off, but may be attached to the body of the
carriage or other convenient position; H represents the spring.
According to my Invention the axle A may be connected to the
corresponding axle on the opposite side of the vehicle, as shown by the
dotted lines a, or they may in other cases where preferred be entirely
seperate.
Having now described the nature of my said Invention and in what
manner the same is to be performed, I would have it understood that
I do not confine myself to the exact form shown in the Drawing, as it
may be obviously altered to suit the various vehicles to which my
Invention may be applied; but what I do claim is, the method of adjust-
ing the bodies and shafts or poles of vehicles to suit animals of various
heights by the application of my improved bar or frame, screws, and
guide bars in combination so that the shafts or pole and body of the

page_text: vehicle can be raised or lowered at pleasure by turning the screw,
substantially as herein described and illustrated.
In witness whereof, I, the said George Tooley Tietjen, have here-
_unto_set_my_hand and seal, this. Fourteenth-day of July, in the
year of our Lord One thousand eight hundred and seventy. -
