GERARD WENZESLAUS VON NAWROCKI, of the Firm of J. Brandt and G. W.
v. Nawrocki, Patent Agents, of No. 124, Leipziger Strasse, Berlin, in the German
Empire. "AN IMPROVED TRUCK OR CARRIAGE FOR CONVEYING LUGGAGE OR
GOODS ON TRAMWAYS." [A communication by Julius Ascher, of Berlin, in the
German Empire.]
The present Invention has for its object the providing of means for enabling
persons travelling by tramway cars to take luggage with them, as in railway trains,
for which there is at present no provision made.
For this purpose a light truck is provided, mounted by preference on a single
pair of wheels, and capable of being readily coupled to the one end of the tram car
by any suitable coupling, such as an arm at one end of the truck, which is
inserted between a fork on the tram car, and connected thereto by a linch pin.
Means are provided whereby the weight of any luggage placed upon the truck is
indicated, so that it may be charged for according to a scale of fares. The truck
consists for this purpose of an under framing resting with caoutchouc or other
springs upon the cranked axle of the wheels, and carrying an open shallow box
within which is a loose platform. This platform has at its middle a strong stem
projecting down from its underside between guide rollers on the framing, and
resting with its lower end on the middle of a crosshead, the ends of which are con-
nected by links to levers that are pivotted to the framing and bear upon springs,
which thus support the weight of the platform and of any load upon it.

page_text: To the platform is also connected a toothed rack in gear with a pinion on a
spindle carried by the framing, and extending to the end of the truck, where it is
provided with an index moving over a graduated scale on the end surface of the
truck.
Thus on any luggage being placed on the platform the latter will sink down
somewhat in compressing the supporting springs, and at the same time the rack
connected thereto will turn the pinion and consequently the index of the scale to a
corresponding extent, thus indicating the weight of the luggage.
The truck, if supported only on a single pair of wheels, may have at its one end
a small additional wheel carried by an arm or eccentric, which when the truck is
connected to the tram car is turned up underneath the framing, but is turned down
so as to offer an additional support when the truck is uncoupled.

DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a side view of a tram car with a luggage truck, according to this Inven-
tion, attached to it; Fig. 2 is an end view of the truck; Fig. 3, a transverse section;

Fig. 4, a longitudinal section; and Fig. 5, a half plan under the platform; the
other Figures shew details of construction hereinafter referred to. "As shewn in
the Figures, the truck is made to run on two wheels; it might however have four
wheels. The underframing consists of an exterior rim a, with diagonal ties b
shaped to form in the centre a ring c; this framing rests on caoutchouc springs d
(Fig. 6) on the boxes of the axle f, which is cranked down in its middle. On the
underframe is fixed a casing g, within which the luggage platform A is free to
move up and down. This platform is perforated or made of open work to permit
rain to run off. It rests by its central stem h on a crosshead k, of which a side
view and a plan are shewn in Fig. 7. The crosshead k has at each end two knife
edges engaged in the eyes of links c, by which it is connected to four levers that
bear on springs m', shewn in side view, plan, and section at Fig. 8. For these

page_text: helical springs or springs of other forms might be substituted. In the ring c of the
underframe are mounted antifriction rollers o, between which the stem h is guided.
To the platform A is fixed a rack p, which, as shewn in Fig. 9, gears with a pinion r
on a spindle that extends to the end of the truck, and has on it an index 8 moving
over a graduated dial, so as to indicate accessions to the weight of luggage placed
on the platform by shewing the amount which it is caused to descend, compressing
the springs m¹. The truck is connected to the car by a coupling, which may be of
various forms to suit the coupling link or hook of the car, as indicated at Fig. 10.
At the hinder end of the truck is a roller y, on which the truck can rest when it is
uncoupled from the car and tilted, as indicated by the dotted lines in Fig. 4. This
roller may have an eccentric bearing, as shewn, on a spindle, by turning which
partly round it may be more or less depressed.
.
Having thus described the nature of this Invention, and in what manner the
same is to be performed, as communicated to me by my correspondent, I claim,-
First. The use in combination with a tramway car of a luggage truck constructed
substantially as herein described.
Second. The use in combination with a tramway car of a luggage truck having
a balanced platform, with apparatus for indicating the weight of luggage or goods
thereon, substantially as herein described.
In witness whereof, I, the said Gerard Wenzeslaus von Nawrocki, have here-
unto set my hand and seal, this Twelfth day of April, in the year of our
Lord One thousand eight hundred and eighty.
