page_text: JAMES WILLIAM HAYNES and WILLIAM WHIELDON of Number 42 Devonshire
Chambers, Bishopsgate Street without in the City of London Engineers do hereby
declare the nature of our invention for IMPROVED ATTACHMENTS TO TRAMCARS
LOCOMOTIVES AND VEHICLES FOR THE REMOVAL OF OBSTRUCTIONS ALSO APPLICABLE
AS A BRAKE to be as follows:-
"
so fixed
We construct and fix to the framework, axle or axleboxes of the vehicle in
advance of and in a line with the wheels a rod which we call the "Guard
or suspended vertically by means of a pin or hinge or flexible spring freely to move
backward or towards the wheel when acted upon, the lower end approaching nearly
unto the road or rail.-Between the "Guard" and the wheel we place a block or
catcher suspended or held to the framework of the vehicle by a bolt through a hole
in the block, or it may be by a fixed bolt or bolts through one or more slots in the
block, the same being connected to the "Guard" by means of a chain, rope, wheels
levers or cranks or any combined in such manner that upon the "guard" being
displaced from its vertical position it will cause the bolt to be withdrawn or the
levers or other alternative appliances to act thus releasing the block or catcher
which immediately falls in front of the wheel and onto the road or rail and
effectually intercepts from the wheel the object or obstruction on the road or rail
which caused the "guard" to move-The "guard" and block or catcher may be of
iron, wood or other suitable material in one or more parts.
The block or catcher may be of a concave form on one side to act as a break
upon the wheel and the bottom may be flat to brake upon the road or rail The
other or front side may be wedge shaped or concave or simply square or splayed,-
in the wedge or concave shape that it may slide underneath the obstruction and
carry it forward & in the square or splayed shape that it should push the obstruction
forward or out of and away from the line of the wheels.

page_text: We JAMES WILLIAM HAYNES and WILLIAM WHIELDON of 42 Devonshire
Chambers, Bishopsgate St in the City of London Engineers do hereby declare the
nature of our Invention for AN IMPROVED ATTACHMENT TO TRAMCARS Loco-
MOTIVES AND VEHICLES FOR THE REMOVAL OF OBSTRUCTIONS, ALSO APPLICABLE
AS A BRAKE and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
We construct and fix to the framework axle or axlebox of the vehicle in advance
of and in a line with the wheels a rod which we call "the Guard" so fixed or
suspended vertically by means of a pin or hinge or flexible spring freely to move
backward or towards the wheel when acted upon the lower end approaching nearly
unto the road or rail.
་
Between the "Guard" and the wheel we place a block or "catcher" suspended
or held to the framework of the vehicle by a bolt through a hole in the block, or it
may be by a fixed bolt or bolts through one or more slots in the block the same
being connected to the "guard" by means of a chain, rope wheels levers or cranks
or any combined in such manner that upon the guard being displaced from its
vertical position it will cause the bolt to be withdrawn or the lever or other
alternative appliance to act thus releasing the Block or catcher which immediately
falls in front of the wheel and on to the road or rail and effectually intercepts from
the wheel the object or obstruction on the road or rail which caused the "guard'
to move.
"
The "guard" and Block or catcher may be of Iron wood or other suitable
material in one or more parts.
The Block or catcher may be of a concave form on one side to act as a brake
upon the wheel, and the bottom may be flat to brake upon the road or rail-the
other or front side may be wedge shaped or concave or simply square or splayed.
In the wedge or concave shape that it may slide underneath the obstruction and
carry it forward-or in the square or splayed shape that it should push the
obstruction forward or out of and away from the line of the wheels.
The chief features of our invention are shewn on the accompanying drawings:-
Figs-1. 2. 3. 4 represent a leading wheel of a tramcar or other vehicle A is the
block or "catcher" retained in position on the bar C (which is attached to the axle
box,) by the slide rod D which slide rod is acted upon by the "Guard" B when the
same guard is deflected from its perpendicular position which deflection must occur
upon the "guard" passing any obstruction on the line of wheels.
Fig 2 is a modification of the same arrangement.
Fig 3 shews the block of "catcher" held in position by a simple bolt E through
lugs on the same and on the bar C and connected by a chain G with the guard B.
Fig 4 shews the same block or catcher released the guard having passed against
the obstruction F.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is :-
"
1. The suspended rod or lever called the "Guard" placed in advance of the
block or catcher in front of the wheel, which upon being deflected from its
normal perpendicular position, acts directly or indirectly to release the fastenings

page_text: or holdings of the said block or "catcher" which consequently falls on to the road
or rail in front of the wheel.
2. The attachment to the Axle or Axle box of the vehicle the bar or support
which carries the "Guard."
3 The several arrangements for the interception and removal of obstructions
and prevention of bodily injury in cases of accident substantially as hereinbefore
described and shewn on the Drawings herewith.
