Apparatus for Braking, Stopping, and Starting Tram Cars and other
Vehicles.
I AUGUST WEISSENBORN of 38 Birchfield Street Poplar in the County of Middlesex
Coach Painter dó hereby declare the nature of my invention for BREAKING STOPPING
STARTING TRAM CARS and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention has for its object. 1.) The immidiate stopping of the car. 2.) The
checking of the speed of the car. 3. Utelising the power accumulated in stopping
the car for the purpose of restarting it in either direction. 4.) Abbilitis to stop either
pair of wheels.
To carry out this invention, I fix on one of the axles of the car near the car wheel a
toothed wheel (a) under this toothed wheel within guides (b) I place a toothed rack (c)
one end of this rack has a shoulder or stop (d) to keep the rack within the guides, to
the other end of the rack is attached a powerfull spring (e) then through the
stays (f) I place four cranked levers (g) (h) with rollers where they touch the rack.
The arms of the levers (9) are connected with the rod (i) the arms of levers (h) in a
similar manner with rod (k.) In order that the levers may be kept in proper position
springs (1) are fixed as shown.
Having made on the other axle but on the opposide side of the car a precisely
similar arrangement I connect both by an arm (m) which works on fixed centre on
the bottom of the car, the ends of arm (m) where they are connected with racks should
have sufficient play.
When the driver wishes to apply the break by means of a suitable lever handle pull
rod () the levers (g) will raise the rack to the toothed wheel as shown in Fig. 2.
this toothed wheel will engage the rack pull both springs (e) and force the other rack,
which then is out of action in the opposide direction and so stop the car.
Then the driver should pull rod (k) by means of a similar handle, the levers (h.)
which are attached to it, thereby raise the other rack to the toothed wheel. He is
then at liberty to start the car in either direction by releasing one or the other handle
vis appliing the stored up power on one or the other axle.

page_text: If the driver wishes to stop the car immitiataly pull rod () first which will stop
front axle, then rod (i) which will stop the other axle or he should pull both handles
at the same time.
By pulling rod () and releasing it allmost directly he will be able to slacking the
speed of the car, also can he stop each axle seperately, by pulling one or the other rod.
Fig. 3-4 is arranged in the following way:
I fix on each side of the axles near the car-wheels a toothed wheel (a) under the
toothed wheels within guides (4) I place two toothed racks (e) each end of those racks
has a shoulder or stop (d) near each toothed wheel are two cranked levers (g) placed
through stays (f) The arms of the cranked levers are on each side of the car are
connected by a rod (J) on one end of the rods springs (1) are fixed to keep the levers
in proper position when break is out of action. On each of the other ends of the rods
two small chains are fixed. On one of those chains on each rod (J) is attached rod (i),
and on each of the other chains by means of a cranked lever (n) is attached rod (k.)
Both toothed racks are connected by arm (mi) which works on fixed centre on
bottom of the car. The springs (e) are fixed in opposide direction on arm (m) as
shown.
The driver applies the break in the same manner as discribed in F 1-2. but is not
able to stop each axle seperately but it will act more powerfull in stopping and
starting a car, as it will allways act on both axles. vis transmitting the stored up power
from one side of the axles to the other side.
I would observe, that I do not limit myself rigidly to the above describtion as the
construction and arrangemend are susceptible of considerable modificatian without
departing from the nature and object of my invention.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is
1. The combination of a break stopping and starting Apperatus for Tram Cars and
other vihicles of a like nature to act supstantially in the manner and for the purpose
hereinbefore described and illustrated in the drawing annexed.
2. The storing up of power by stopping a car and utelising the same to restart the
car in either direction, either by transmitting the said power from one axle to the
other, as shown in Fig. 1-2 or transmitting the said power from one side of the axles
to the other as shown in F. 3-4.
3. The immidiate stopping of a vihicle.
4. The stopping of either axle of a vihicle seperately.
5. The checking of the speed of a vihicle all arranged in the manner and for the
purpose as described and represented in the drawings annexed.
AUGUST WEISSENBORN.
