COMPLETE SPECIFICATION.
An Improved Combined Automatic Fender and Brake for Tram-cars
and the like.
I, WILHELM MAEK, of No. 54, Dessauer Strasse, Hannover, in the Empire of
Germany, Engineer, 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 present invention relates to an improved combined automatic fender and
brake for tram-cars and the like, the purpose of the invention being to so con-
struct this kind of device that as soon as the progress of the car is obstructed
the brake automatically acts, thus preventing a person or the obstructing article
to be run over.
In order that those skilled in the art to which this invention appertains may
understand how to make and use the same, its construction and operation will
now be described in detail, referring to the accompanying drawings, forming a
part of this specification, in which
Fig. 1 is an elevation of a portion of a car, showing the fender and brake in
their elevated or inactive position.
Fig. 2 is a plan view of the fender and brake, and
Fig. 3 is an elevation of a portion of a car, showing the fender and brake in
their active position.
In carrying out my invention as here embodied I pivot to the under side of
the platform a of the car two arms bb. Pivoted to these aims are the supporting
rails cc for the fender frame d. These rails are transversely connected by a
metal rod e, which latter carries at either end a connecting bar f, the other end
of these connecting bars f being pivoted to the brake levers g.
The brake levers 7 are mounted on a rod h journaled in brackets secured to
the underside of the car shortly in front of the wheels in such a manner that their
shorter extremities point towards the wheels. A weighted cross beam k connects
the two shorter extremities. The longer extremities carry the brake i.

The fender frame d may be fitted up so as to offer a soft or yielding surface to
the obstructing object, an elastic cover 7 preferably serving for the purpose which
may be made of any well known and suitable material.
The operation of the device is as follows:-
The fender, slightly protruding beyond the end of the car, and located a short
distance above the road surface, coming in contact with an obstruction, the
frame d will be pressed back, thereby causing the connecting bars of mounted
on the rod e in connection with the fender rails c to move backwards and conse-
quently to press downwards the brake levers g and to apply the brake i to the
rails. The brake remains in action until the obstruction is removed from the
fender when the parts will return to their original position by virtue of the
weighted beam k on the shorter extremity of the brake levers, the weight of which
beam k is so chosen that it will normally hold the brake and fender above the
road surface the free extremities of the arms b, b preventing the fender from

inoperative position.
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:-
:―
An improved combined automatic fender and brake for tram-cars and the like,
the whole constructed arranged and adapted to operate, substantially as described
with reference to the accompanying drawings.
