I, MAXIMILIAN KRAUSE, of 1B, Tempelhofer Ufer Berlin in the German Empire,
Merchant, hereby declare the nature of this invention and in what manner the same
is to be performed to be particularly described and ascertained in and by the following
statement:
The present invention relates to an improved brake mechanism for vehicles of all
kinds propelled otherwise than by the rider. The said mechanism consists of two
brake bands each of which is applied to one hub of the hinder wheel axle and also of
an apparatus serving to draw the said brake bands tight. This apparatus consists of
a clip shaped mechanism the limbs of which engage with their free ends in loops or
holes of the brake band, and have their other ends connected with a bar, which can
be drawn by means of a draw rope which is passed over a rope drum provided with
a check mechanism. The release of the check mechanism and the drawing of the
rope is effected by means of a treadle lever. The purpose of the invention is to effect
a more certain action of the brake mechanism and the application thereof in a
convenient manner so that by simply pressing down the treadle lever by means of
the foot the brake mechanism can be actuated from the driver's box without
causing any interruption of the other duties of the driver. In the accompanying
drawing the brake mechanism of my invention is illustrated by way of example :
Figure 1 is a side view of a conveyance provided with the brake mechanism.
Figure 2 is a view from above of the brake mechanism in the released
position.
Figure 3 shows a portion of the hind wheel axle in front view and illustrates
the arrangement of the brake band and the action thereof with the drawing
mechanism.
Figure 4 is a detail which illustrates the connecting part between the brake band and
the actuating mechanism in front and side view.
Figure 5 shows an arrangement of the brake band in sectional view.
Figure 6 shows a side view of the treadle lever and the rope drum in the position
of rest.
Figure 7 is a side view of the treadle lever and the rope drum when in
action.
Figure 8 is a view from above of Figure 7.
Figure 9 is a front view of Figure 7.
Figure 10 is a detail which illustrates the arrangement of a retaining catch of the
check mechanism in section and in side view respectively. Each hub B on the hind
wheel axle A bears a brake ring C (Figure 5), which is surrounded by the brake
band a.
One end of the said brake band a is provided with an eyelet a¹ the other
end thereof bears a bolt a² on which a lever b with an eyelet 61 is fixed (Figure 3).
The end of the bolt a² is provided with a screw thread, upon which a nut b²
and nut are screwed in order to secure the lever b. The free ends of the
levers are connected to the drawbars c each of which possesses an adjusting
device c¹. (Figure 2). The drawbars c come together at their ends and are connected
to a chain d which passes over a roller e and is fastened to an angle lever f whose
arm f is formed in the shape of a crescent. The rope d¹ is attached to the other

page_text: arm of the angle lever f which rope passes over the guiding rolls g g¹ g³ g³ and is
secured to the check wheel h of the actuating mechanism (see Figure 1).
The lever bis connected elastically with the brake band a so that a spring action is
obtained upon actuating the brake mechanism and thereby any breakage of the
parts is avoided. For this purpose the lever b is provided with a guiding loop i in
which is inserted a spring k the other end whereof is fixed to the piece 7 (see Figure 4).
The piece is bent at a right angle; the vertical arm passes through an eyelet of
the lever b and is secured in its place by means of nut 12. The arm ¹ bears moreover
a horizontal projection m which is inserted in the eyelet a¹ of the brake band. The
horizontal arms of the piece engages by means of the guiding piece under the
hind wheel axle A and is held fast by means of the part 15. The part bears a
spring n the other end of which is attached to the brake band a and which
Berves to lift the brake band a from the brake ring C when the brake
mechanism is released. The rope d of the drawing mechanism passes over
the rope drum o which is either attached firmly to the check wheel h or
formed in one piece with it (see Figures 6 and 7). The shaft o¹ of the latter bears
the arms o connected to a plate o³ which is secured to the foot board of the driving
seat. The drum shaft o¹ has moreover a treadle lever p which passes through a slot
in the supporting plate o³ and is provided with a treadle p¹. This treadle lever p
can be depressed from the coachman's seat against the tension of the spring p², and
possesses a locking bolt q placed in a holder q and under the influence of a spring q¹;
the said bolt engages in the teeth of the ratchet wheel h of the drum o when the
lever pis depressed, and thus causes the drum to revolve correspondingly, and to
wind up the rope d' (see Figure 7). The return motion of the rope drum o is
effected through the return motion of the lever p caused by the tension of the
spring p, whereby the bolt q2 is caused to slip over the teeth of the ratchet wheel h,
being prevented engaging through a second bolt 2 (Figure 10) fixed to the supporting
plate and also working in a cover and placed under the action of a spring 1,
which bolt engages in the teeth of the ratchet wheel h. By a repeated depression of
the lever pa gradual tightening of the brake is caused which can be increased to
any desired amount. In order to effect a rapid release of the brake mechanism
there is fixed revolubly on the bearing plate o³ a second treadle lever s. This
lever is connected with a lever transmitting gear 81 82 the one limb 82 whereof
is placed under spring pressure and engages with its free end under a projection t
of the ratchet bolt Upon the depression of the lever 8 the catch 2 is
consequently raised by means of the limb 82 in opposition to the action of the
spring whereby the ratchet, wheel h of the rope drum o is. released, so that
the brake mechanism can be brought back again into its original position by the
tension of springs or the like. placed at suitable positions. These springs are not
specially illustrated in the drawing.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a brake mechanism for traction vehicles, the combination of two brake
bands a surrounding the hubs B of the hind wheel axle. A with means for effecting
the application of the brake bands actuated from the coachman's box, substantially as
above described and for the purpose set forth.
2. In a brake mechanism. the combination of brake bands a on the hubs B of the
hind wheel axle A with a mechanism for actuating the same and with means, for
setting the said mechanism in motion by the drawing up of a rope d¹ from
the coachman's box, substantially as above described and for the purpose set
forth..
3. In a brake mechanism the combination of brake bands a on the hubs B of the
hind wheel axle A. with a spring device and an actuating device in which latter a
rope d¹ passed over a rope drum o is drawn up by depressing a treadle lever p from
the coachman's box and can be held fast by means of a ratchet wheel h with bolt

page_text: connected to the rope drum o the release whereof may also be effected from the
coachmans box by means of a second treadle lever 8 substantially as and for the
purpose above described..
