Improvements in Carriage Brakes.
i
We ROBERT TUCKER and FREDERICK BOYLING, Coach Builders, Danger
Street, Armidale, in the Colony of New South Wales, do hereby declare the nature
of the said invention for Improvements in carriage brakes to be as follows:-
We attach a rod to the spur from the main shaft of an ordinary brake and carry
>ther end of this rod to the front of the carriage and fix it to the shafts, pole, horse,
horses or harness in such a manner that when the carriage is going down an incline
or otherwise when the horse leans backwards it presses the rod and thus forces the
brake onto the wheels. It can be locked on or off the wheels by a lever worked
by the driver's foot or otherwise.
The idea of this arrangement is to work the brake by the motion of the horse
instead of by the hand or foot levers. This invention is particularly suited for a
Hansom cab. The above mentioned brake is suited for both two and four wheeled
vehicles.
Dated the First day of August 1894.

We ROBERT TUCKER and FREDERICK BOYLING, Danger Street, Armidale,
New South Wales, Australia, Coach Builders, do hereby declare the nature of our
invention for Improvements in carriage brakes to be as follows :-
:-
The idea is to work the brake automatically by the sliding shafts or pole, and
the backward pressure of the horse or horses when going down an incline or
stopping.
This invention relates to two or four wheeled vehicles, and more especially to
automatic brakes: and the object of the same is to effect certain improvements in
brakes of this character.
To the end the invention consists in the specific details of construction herein-
after more fully described and claimed as shown in drawings wherein the
corresponding letters in drawings represent the corresponding parts of brake in
various positions.
K is a

journal with the foot fixed under the front axle. P is the axle. O is the
axle bed. L is a sliding bar which slides in journal marked K and carries the
shafts marked N in place of the ordinary jack clips, thus the backward pressure of
the shafts forces back the sliding bars L also the connecting rods J and. E and
forces the brake on the wheels by the spurs H and I and pulling the shafts
forwards takes the brake off. The front joint of connecting rod E and marked F

through the bottom of the body or otherwise and to be worked by the hand, and
by pulling the joint F to the top of the slot reverses the action of the brake,
thus when the joint F is at the bottom of the slot G. the backward pressure of the
shafts or pole applies the brake to the wheels. And when the joint F is at the top
of the slot G the forward motion of the horse pulling the shafts applies the brake
to the wheels, the connecting rod J is connected at the front end to bar marked W
as shown in Drawing No. 2. Q is a sliding bar and is connected to brake by a
short spur off the main shaft and slides to and fro in journal marked S with the
motion of the brake, S is fixed to bottom of body.
T is a lever which has a screw at its lower end and this screw travels through
one side of journal S, and by pushing the lever T forward forces the screw on the
bar Qand stops the action of the brake, and enables to lock the brake on or off
the wheels (see Drawing No. 4 showing front view of T. S. Q) the lever T is
carried up to be worked by the foot or hand. Y is a steel band which operates
on the inside stock hoops of hind wheels.
R is a lever which is carried on a stud marked X in Drawing No. 3 and the
steel band Y is so fixed on the lever R, that when the lever is forced backwards
the steel band clasps the stock hoop and in this way forms the brake (see
Drawing No. 3).
Drawing No. 2 is a top view of No. 1 drawing but in place of the band brake,
it shows the application of the ordinary tire brake to our invention: this alteration
is done by carrying the spur otherwise arm marked 1 (in No. 1 drawing) to carry
the brake blocks. U is the main shaft. W is a bar connected at each end to
sliding bars L and is connected to brake by rod J. M is a spring fixed to the
axle bed (or as shown on English shafts in Drawing No. 6 and No. 7) this
spring gives an elastic pull to the shafts and eases the horses' shoulders when
pulling.
Drawing No. 3 shows a back view of brake. Z is section of stock of wheel. X is
a stud which carries lever R. this drawing shows the application of steel band
and the mode of fixing stud to axle and axle bed. P is the axle. O is the

Drawing No. 6 shows a top view of English carriage shafts and instead of
the journals marked K being fixed under the axle they have a block (see
Drawing No. 8) this block is fixed in the futchel irons (or irons into which the
shafts are ordinarily fixed) of undercarriage. (see Drawing No. 5).
Drawing No. 7 shows a top view of pole and splinter bar for English carriage.
PP is the pole. X X is the splinter bar. The splinter bar is fixed in the sliding
bars L where the shafts are taken from.
Drawing No. 8 shows a side view of pole and splinter bar, B B is a journal
and is fixed to the undercarriage. C C is a sliding bar fixed on end of pole
and slides in journal B. B. thus enabling the pole and splinter bar to slide
together.
Drawing No. 9 is a side view of the brake on a Hansom cab, and the
letters R. D. Y. P. S. Q. are described in No. 1 and No. 3 Drawings.
BK is a bracket fixed to the body and carries a semicircle marked E. E. by
a joint in centre of semicircle in a manner that the ends of semicircle can. be
worked up and down by the drivers foot, and having a cord or wire fixed to each
end of semicircle and the other ends carried separately under the body. as
marked CD to the lock and is fixed to each end of a horizontal cross lever
(see Drawing No. 10) which has a screw in the centre of lever, this screw travels
upwards through the bottom of journal S and by pushing one end of semicircle E E
down pulls the cord ou opposite end of semicircle, thus pulling one end of cross
lever and forces the screw on the sliding bar Q and stops the action of the brake
and pressing the opposite end of semicircle pulls the other cord which releases

page_text: the sliding bar S T. A. G. and L L. form a semicircle sliding in a slot under the
shafts as described in Drawings No. 11 and No. 12.
Drawing No. 11 shows a section top view of semicircle as shown on cab shafts.
J. N. is a joint where it is connected to brake. A G is an angle iron with a slot
in it and is fixed under the shafts.
S. T. is a stud on the semicircle and slides in the slot in angle iron. The
semicircle is carried preferably round under the shafts and takes the horses
breeching in loops L. L. and when the horses breeching tightens by his leaning
backwards forces the semicircle back and applies the brake.
Drawing No. 12 is a side section of semicircle.
Drawing No. 10 is a section front view of Hansom cab, the stud marked X is
fixed under the axle and the lever R is pointing downwards.
Drawing No. 13 shows the mode of sliding the shafts in a slot otherwise slots.
Drawing No. 14 shows the mode of sliding the shafts in a tube otherwise using
the sliding bars in a long journal.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. The mode of working the brake automatically by the sliding shafts or pole
as follows:-Sliding the shafts or pole by means of journals otherwise bosses or
tubes and sliding bar as described in drawings.
2. The mode of bringing the brake in contact with the horses breeching or
breech band for the purpose of working the brake by means of a semicircle or
any suitable shape and the application of semicircle to the shafts and the mode
of connecting semicircle to the brake as described in the Drawings No. 9. No. 10.
No. 11. No. 12.
3. The mode of reversing the action of the brake by means of the slot link
marked A. G. in Drawing No. 1 and the sliding joint and the node of application
of same combined with arm marked B as described.
4. The mode of locking the brake on or off the wheels by means of a journal
otherwise boss or tube and sliding bar and a lever with screw attached, and the
mode of application of same combined for the said purpose as shown in
Drawings No. 1 No. 4, No. 9.
5. The mode of applying the band marked Y to the lever R by having the
ends of band fixed above and below the fixed centre of the lever, thus when
applying the brake the lever has a pull on both ends of the band, and the
application of the stud ✗ the lever R and the band Y combined as shown in
Drawings No. 1. No. 3.
6. The mode of connecting the brake with the sliding shafts or pole by means
of the cross bar marked W which is connected to the brake by a joint and each end
taking the pressure from the shafts or pole as described in Drawing No. 2. No. 6.
7. The mode of working the lock on Hansom cab by the drivers foot as
described.
8. The mode of sliding the shafts in slots as described in Drawing No. 13.
