An Improved Safety Guard and Obstruction Remover for Tramway
Engines and Tram Cars.
JOE POGSON Tramways Manager Bridgefield House Huddersfield Yorkshire do
hereby declare the nature of this invention to be as follows:-
My invention relates to safety-guards and obstruction removers for tramway
engines and tramcars.
According to my said invention I mount at both ends of engine and car, at a
convenient height above the ground level a suitable frame constructed to project
some distance from the said engine or car and forming an obtuse angled or wedge-
like or other suitably shaped guard, to the face of the said frame and extending
the whole length thereof. I fix a strong piece of india-rubber or other elastic
substance or composition. The said india-rubber, or other elastic substance pre-
ferably projects forwards and downwards from the lip of the guard frame nearly
to the ground level and forms an elastic safety-guard and obstruction remover.
When the said safety guard comes in contact with a heavy obstructive body on
the ground it is bent downwards and caused to approach nearer the ground and
thus prevents the said body passing underneath it.
.
Moreover the sloping sides of the safety guard tend to slide the obstructing
body sideways out of the path of the engine or car. preferably mount the
said guard frame so as to be readily detachable, and I may moreover hinge it at
its rear end to the engine or car frame and support its forward end by a spring
or balance weight and provide lever or other connections whereby the engine
driver may depress the said forward end at will, so as to bring it nearer the
ground level in case of emergency. Or the frame being balanced as hereinabove
specified the pressure of any obstructing body in front of the said frame will
depress the same automatically in addition to bending the elastic portion of the
safety guard in the manner above described. In some cases where I do not desire
automatic depressing action I may support the frame at the forward end by a
catch or other positive device and I may arrange that this said eatch or other
retaining device may be liberated by the engine driver at will. 1 prefer to so
connect the frame to the steam or other power brake apparatus when such is
I thus
used that the descent of the frame shall automatically apply the brake.
provide that by depressing or operating lever only the driver shall be able to
simultaneously lower the safety-guard and apply the steam or other brake to
engine and car in case of emergency while allowing the steam or other power
brake to be applied without lowering the safety guard when desired. Moreover
owing to the connection between the safety guard and the steam or other power
brake apparatus the descent of the said guard when caused automatically by the
pressure of an obstructing body will also apply the brake to both engine and car.
The guard frame is preferably made adjustable for height to regulate the
clearance from the ground as the wheel tyres wear.

An Improved Safety Guard and Obstruction Remover for Tramway
Engines and Tram Cars.
I, JOE POGSON, Tramways Manager, Bridgefield House, Huddersfield,
Yorkshire, 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 :-
My invention relates to safety guards and obstruction removers for tramway
engines and tramcars.
According to my said invention, I mount at both ends of engine and car, at a
convenient height above the ground level a suitable frame constructed to project
.some distance from the engine or car and forming an obtuse angled or wedge
shaped guard. To the face of this frame I fix a strong piece of india_rubber or
other clastic material projecting forwards and downwards from the lip of the guard
frame nearly to the ground so as to form an elastic safety-guard and obstruction
remover; when the safety-guard comes in contact with an obstructive body on the
ground, its elastic front is bent downwards and caused to approach nearer the
ground, thus preventing the obstructing body from passing under it. Moreover
the inclined sides of the safety guard tend to cause the obstructing body to slide
sideways out of the path of the engine or car.
Fig. 1. of the accompanying drawings is a front elevation, Fig. 2 is a side
elevation and Fig. 3. is a plan of a safety guard according to my invention applied
to the front of a tramway engine. A is the frame made with two inclined sides to
which is attached the india rubber or elastic material B which slopes forwards and
downwards nearly to the ground.. For convenience of adjustment I fix the
frame A at each end by brackets C having slotted holes and in the middle by a
bolt D secured by adjusting nuts in the bracket E for the coupling. The frame
thus held can be readily detached or adjusted nearer to or farther from the
ground.
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 :-
A safety guard or obstruction remover for tramway engines and tram cars
consisting of a wedge shaped frame with elastic material sloping forwards and
downwards from the frame, substantially as described.
