I do hereby declare the nature of this invention to be as follows:-
This invention consists of four iron bars two to be the same length and the other
two to be one longer than the other and bolted together at the ends and two bolts in
long bars to fasten it to the car or vehicle and a cylinder with a spring in it to be
fastened to the car or vehicle and one piece of iron to be bolted to the bar nearest the
spring to press against spring. All to be fastened under the body of car or vehicle
two sets of bars and two springs and cylinders required the springs to be powerful
this is to take the strain of the horses when starting or drawing the car or vehicle
and they are to be fastened at each end of car or vehicle.
Dated this 19th day of February 1890.

COMPLETE SPECIFICATION.
Improved Means or Apparatus for Preventing Shocks or Sudden
Strains in Starting or Drawing Tramcars or other Vehicles.
1, EDGAR ALLEN CHATTERTON, of 62, Ramsey Road, Forest Gate, in the County of
Essex, Carpenter, 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 object of this invention is to fit tramcars and other vehicles with means or
apparatus for preventing shocks or sudden strains in starting or drawing, thereby
considerably minimising the risk of injury to the horses or other draught animals by
the violent strain necessary for starting the iramcar or other vehicle as ordinarily
constructed.
The invention consists of an arrangement of levers in combination with spring
buffers, the tractive power being applied to ropes, chains, rods, or other connections
secured to the levers.
In order that my invention and the manner of carrying it into practice may be well
understood I will describe it with reference to the accompanying drawing which
shews an underplan of my invention as it would appear when fitted on the under
frame of a vehicle.
The chains, cords, rods, or other connections T are connected to the whippletree or
traces as found convenient. Each chain, or other connection T is secured to a lever
frame, but as the lever frames are duplicates of each other, a description of one of
them will serve for both. Each lever frame consists of two levers A and B of equal
length pivoted to the underframe S of the vehicle at C and R respectively, and
joined at their ends to the link levers E and H. Preferably the connection between
the link H and the lever B is a pin or bolt P, on the link riding in a short
longitudinal slot Q in the lever B, or vice versa to prevent too rigid a connection
between these two parts.
To the long arm of the lever B but near to the fulcrum bolt R, the end V of the
buffer rod or plunger U is jointed. The other end of the buffer rod or plunger U
bears on the buffer springs X in the cylindrical or other shaped case Y which is
firmly secured to the underframe of the vehicle. The chain or other connection T
is secured to the lever frame at the joint J of the lever A and link E. It will be

page_text: understood that the two lever frames shewn in the drawing are attached to the under
frame in such manner as to work in different planes.
When the tractive power is applied to the whippletree or traces it will be
transmitted by the chains or other connections T to the lever frames turning the
levers on their fulcrums thereby compressing the buffer springs X which, pressing
against the front end G of the underframe S, urge the vehicle forward.
The arrangement of mechanism herein before described is shewn as applied to one
end of the vehicle only and is therefore adapted for ordinary road vehicles which
progress in one direction only. For tramcars and such like vehicles propelled from
either end, a similar arrangement of mechanism is applied to each end of the car.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The arrangement of links and levers hereinbefore described and shewn combined
with buffer springs in cases attached to the end of the underframe of the vehicle
operating substantially in the manner and for the purpose set forth.
