PROVISIONAL SPECIFICATION.
An Improved Device for Facilitating the Starting of Vehicles.
We PETER DANIEL VÖLKER of 23 Fleischmengergasse, Cologne, Turner,
and HUBERT STAMMEL of 9 Freiheitstrasse Cologne-Deutz, Dentist, do hereby
declare the nature of this invention to be as follows:-
The object of this invention is to provide means by which the starting of vehicles
from a position of rest may be made more easy for the animal drawing them, thus
tending to prevent the straining of such animal or animals, and prolonging their
career of usefulness.
The improved device is one in which the period of commencement of draught
is distinguished by the communication of the draught power to the wheel or wheels
through leverage and the device is as follows;-On the wheel axle if rotary or on
the wheel hub, one or both, is fixed a ratchet wheel, and upon the said axle or hub
revolves a frame or arm carrying a sliding pawl or dog adapted to be engaged with
said ratchet wheel and provided with a spring tending to disengage it. On the
said arm or frame is pivoted a bell crank lever whose one arm is adapted to press
the pawl or dog into engagement with the ratchet wheel when the other arm is
pulled by the draw rod to which it is directly or indirectly connected. This draw
rod carries means for attaching the traces or the whiffle bar or similar device to it
and it is provided with a nose or projection adapted when it is drawn out to engage
a lever or pivoted bar which retains it in such position.
This lever or bar may be pressed into operative engagement by a spring or
weight, and released by means of a projecting head or end to which pressure may
be applied by the driver of the vehicle.
The vehicle being in position of rest the draw rod is released from its retaining
bar or lever and is drawn back with the other parts by a spring or otherwise.
When a pull is exerted on the draw bar the bell crank lever rocks and brings the
pawl or dog into engagement with the ratchet wheel, and further pull revolves the
pawl frame and with it the ratchet wheel and the wheel of the vehicle; a start is
thus effected through the leverage of the pawl frame until the drawbar attains its
forward limit where it is retained while the pawl is brought out of engagement at
the same time by a cam operating on a pin at the side of the pawl or by any other
equivalent mechanical device.

An Improved Device for Facilitating the Starting of Vehicles.
We PETER DANIEL VÖLKER of 23 Fleischmengergasse, Cologne, Turner,
and HUBERT STAMMEL of 9 Freiheitsstrasse, Cologne-Deutz, Dentist, do 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 object of this invention is to provide means by which the starting of vehicles

page_text: from a position of rest may be made more easy for the animal drawing them, thus
tending to prevent the straining of such animal or animals, and prolonging their
career of usefulness...
The improved device is one in which the period of commencement of draught is
distinguished by the communication of the draught power to the wheel or wheels
through leverage and the device is as follows:-
On the wheel axle if rotary or on the wheel hub, one or both, is fixed a ratchet
wheel; and upon the said axle or hub revolves a frame or arm carrying a sliding
pawl or dog adapted to be engaged with said ratchet wheel and provided with
a spring tending to disengage it. On the said arm or frame is pivoted a bell crank
lever whose one arm is adapted to press the pawl or dog into engagement with the
ratchet wheel when the other arm is pulled by the draw rod to which it is directly
or indirectly connected. This draw rod carries means for attaching the traces or
the whiffle bar or similar device to it and it is provided with a nose or projection
adapted when it is drawn out to engage a lever or pivoted bar which retains it in.
such position.
This lever or bar may be pressed into operative engagement by a spring or
weight, and released by means of a projecting head or end to which pressure may
be applied by the driver of the vehicle.
.The vehicle being in position of rest the draw rod is released from its retaining
bar or lever and is drawn back with the other parts by a spring or otherwise.
When a pull is exerted on the draw bar the bell crank lever rocks and brings the
pawl or dog into engagement with the ratchet wheel and further pull revolves the
pawl frame and with it the ratchet wheel and the wheel of the vehicle; a start is
thus effected through the leverage of the pawl frame until the draw bar attains its
forward limit where it is retained while the pawl is brought out of engagement at
the same time by a cam operating on a pin at the side of the pawl or by any other
equivalent mechanical device.
This invention is illustrated in the annexed drawing, in which Fig. 1 is a lateral
elevation of the device at rest; Fig. a plan view of the same; Fig. 3. a plan and
Fig. 4 cross sectional view of the trace hook with disengaging arrangement, and
Fig. 5 a lateral view of the trace hook when pulled; Fig. 6 shows the device in
engaging position; Figs. 7, 8, 9 and 10 represent a somewhat modified arrangement
in various positions, for use on ordinary carts.
The dog ce iu guides à d' within the casing a is at its one end connected with one
.arm of the bent lever p, while its other bevelled end serves to engage the ratchet
wheel e.. Upon the dog ca spiral spring m is arranged, which on the one hand
exerts pressure against the cross guide d¹ and on the other against the washer s
rigidly mounted upon the dog e; this spiral spring serves to disengage the dog c
from the ratchet wheel e. To the other arm of the bent lever p which is pivotally
arranged in the case a, the trace-rope or trace rod is fixed, the former passing
over the pulleys i and ', and connected with the trace hook k¹. Displaceable
longitudinally in the casing the trace hook k¹ is made so that, on its being pulled,
the projection or step therein places itself behind the one end of the lever which
is actuated by a spring n and pivotally fixed on to the casing 1; the other end of
this lever being connected with the headed pin 12. The spring n acting upon the
one end of the lever, forces this lever end continuously against the trace hook k¹;
by pressing down the pin the action of the spring n can be nullified. The
spring o on the casing a serves to carry back this casing out of the position shown
in Fig. 6 into that shown in Fig. 1.
For ordinary carts the casing a is placed as represented in Fig. 7, and the bent
lever, p is directly connected with the suitably guided trace rod. On this.rod k*
provided with hook is a pivoted pawl which owing to its weight occupies the
position shown in Fig. 7. The guide k of the trace rod k carries an axle g, with
a nose g¹, and an arm g provided with a counterpoise. "By this arm the axle g
or its nose g¹ respectively is held in the right position for co-operation with the
mawl
1

page_text: The cross bars t t serve to limit the movement of the casing a. On lifting the
arm g the noses g¹ passes beneath the pawl and thus allows the trace rod k³ to
go back.
Above the axle fa guide f¹ provided with a sloping cam is arranged, upon which
slope rests the pulley of an arın c', arranged laterally on the dog c, when the
casing a arrives in the position shown in Fig. 9, which then throws the pin c out of
engagement with the ratchet wheel.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
The improved device for facilitating the starting of vehicles consisting in the
means for engaging the axle or wheel hub, rotating the same and disengaging the
leverage, substantially as set forth.
