COMPLETE SPECIFICATION.
Improvements in Street Car Fenders and Brakes.
We, SAMUEL COLWELL BOLE, Labourer, and JOSEPH G. BEALE, Banker, both of
Leechburg, in the County of Armstrong, and State of Pennsylvania, United States
of America, 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;-
Our invention has relation to improvements in street car fenders, and the object
is to provide a simple, durable and effective device of this kind; and to this end
the novelty consists in the construction, combination and arrangement of the same
as will be hereinafter more fully described and particularly pointed out in the
claims.
In the accompanying drawings the same reference numerals indicate the same
parts of the invention.
Figure 1 is a side elevation of the front end of a street car with our improved
car fender in position thereon;
Fig. 2 is a similar view with the fender in position for use;
Fig. 3 is a bottom plan view of the fender in the position shown in Fig. 1;
Fig. 4 is a longitudinal section of the same;
Fig. 5 is a bottom plan view of the fender in the position shown in Fig. 2; and
Fig. 6 is a longitudinal section of the same.
1 and 2 represent a pair of guide plates permanently secured to the side
beams 3-3 of the car body, their front ends being bent up vertically at each end
of the dashboard to form stanchions 4-4.
5-5 represent two straps pivoted at one end by a bolt 6 on the inside of the
beams 33, their lower ends being pivoted on a stud 7, projecting on each side
of a rectangular frame 8, the sides 9-9 of which are constructed of pipe, through
which pass the rods 10-10, the front or forward ends of which are connected by a
cross bar 12, on which is mounted a rubber tube 13, while their rear ends are
provided with couplings 14-14, connected to a cross rod 15.
16-16 represent two connecting rods, their forward ends pivoted on the
studs 7-7, their rear ends pivoted to the projecting ends of the crank arms 17-17
of the crank shaft 18 hinged in bearings 19-19 underneath the car.
20-20 repre-
sent friction rollers mounted on the crank arms 17, and they are arranged to travel
to and from the car wheels 21-21.
22-22 represent spiral springs encompassing the rods 10-10, their tension being
exerted to press the cross bar 12 and rod 15 backward when the fender is tripped,
as will be hereinafter explained.
23 is an eye bolt on the rod 15, and a chain 24 connects it with the outer end of
a crank arm 25 fixed on the lower end of a vertical shaft 26, extending up through
the front platform, its upper end being provided with a hand wheel 27.
28 represents a cross rod provided at each end with a guide bracket 29, sliding
freely on the rods 10-10. The outer ends of these guide brackets 29-29 are
formed with parallel ears 30-30, which project above and below the guide plates.
31 represents an arm rigidly secured to the cross rod 28, its forward end formed

page_text: with a wedge shaped tongue 32, and immediately above said tongue is an integral
finger 33, having a locking pawl 34 on its upper face, the finger and tongue being
separated by a V-shaped slot 35.
A spring arm 36 is rigidly fixed at one end to the rear rod 15, and it projects
forwardly under the rod 28, its front end extending a short distance beyond the
end of the tongue 32 and terminating in a right angular catch 37.
38 represents an arm rigidly fixed on the rear cross bar 8 of the frame 8, the
rear end of said arm 38 terminating in a wedge shaped tooth 39, corresponding in
shape to the slot 35 in the arm 31.
40 represents a bell crank lever fulcrumed in a vertical slot 41 in the arm 38,
the shorter end 42 of which extends downward, and is adapted to engage the
catch 37 on the spring arm 36 when the parts are brought together. The longer
horizontal arm 43 of the lever 40 is formed with a detent 44, which engages the
pawl 34 on the finger 33 at the same time that the short end 42 of the lever 40
engages the spring arm 36.
The outer end of the arm 43 is formed with an eye 45, which engages the inner
end of a lever 46 fulcrumed in a bracket 47 secured underneath the car, the outer
end of said lever being connected to a vertical rod 48 passing through the front
platform and having a pedal button 49, within convenient reach of the foot of the
motorman.
50 represents the usual flexible fender-netting extending forwardly and down-
wardly from the stanchions 4-4 to the cross rod 82 which forms the front end of the
rectangular frame.
In order to set the fender for use, the hand wheel 27 is turned to the right,.and
through the medium of its crank 25 and chain 24, draws the cross rod 15 forward,
compressing the springs 22-22 until the spring arm 36 engages the shorter end 42
of the lever 40, and at the same time the pawl 34 on the finger 33 engages the
detent 44 on the lever 40. This arrangement forms a positive lock for the fender
in this position, and when in this position the forward end or cross bar 12 is
extended some distance ahead of the rectangular frame 8, and the whole fender is
raised clear of the track. At the same time the friction rollers 20-20 are brought
forward by their connecting rods 16-16 to clear both the track and the car wheels.
When the parts are set in the above position, and there is an obstruction on the
track, the motorman presses down on the button 49. This operation throws the
rear end of the bell crank lever 40 up, releasing the detent 44 from the pawl 34
and, the shorter end 42 from the spring arm 36, allowing the springs 22-22 to
force the cross rods 15 and 28 rearward. This movement also draws the rectangular
frame 8 backward, and as it is pivoted to the side beams 3-3 by the straps 5-5,
these straps allow the frame to drop down so that its forward end touches the track
in front of the car, and at the same time the rods 16-16 force the rollers 20-20
into contact with the wheels and the track, and as the frictional contact of the
wheels with the rollers causes them to rotate in a reverse direction to the wheels,
they act as a brake and bring the car to a stop. It will thus be seen that the device
combines a brake with the fender when the latter is thrown into operation.
Although we have specifically described the construction and relative arrangement
of the several elements of our invention, we do not desire to be confined to the same,
as such changes or modifications may be made as clearly fall within the scope of
our invention, without departing from the spirit thereof.
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. A combined fender and brake, comprising the guide plates 1 and 2, the
pivoted straps 55, the rectangular frame 8, pivoted to the lower ends of said straps,
the rods 10-10 mounted in said frame, 8, the spiral springs 22-22 mounted on
said rods, the cross rod 15 connecting the rear ends of the rods 10-10, and provided
with the eye-bolt 23, the crank arm 25, connected to said eye-bolt

page_text: by a chain 24, and mounted
on a vertical shaft 26, provided with an
operating wheel 27, the spring arm 36 fixed on the cross rod 15, and
the arm 38 rigidly mounted on the cross rod 81 and formed with a vertical
slot 41, the bell crank lever 40 fulcrumed in said slot, and having a

bracket 47, and having its inner end pivoted to said arm 43 and its outer end con-
nected to a vertical rod 48 extending through the front platform, substantially as
shown and described.
2. A car fender and brake, comprising the rectangular frame 8 suspended from

end 42, and its horizontal arm 43 provided with a detent 44, a lever 46 pivoted to
the outer end of said arm and provided with a vertical rod 48 extending upwardly
through the car platform, in combination with the spring arm 36 fixed on the cross
