PROVISIONAL SPECIFICATION.
Improvements in Shunting Levers for Railway and Tramway
Vehicles.
I, ELIND JEDUTHAM KNAPP of 103 Euston Road, London, N.W. Gentleman,
do hereby declare the nature of this invention to be as follows:-
My invention relates to improved means for starting railway and tramway cars,
carriages or trucks.
In accordance with my improvements I employ a rod or bar of iron, steel or any
other suitable metal, having one end of same slightly curved, and attached by
means of bolts nuts & c., to a triangular shaped piece of metal, which I shall here-
after term the "chair" having a lug on each side so as to prevent same from
slipping off the rail.
Upon the bottom of the chair, is dovetailed therein, a triangular shaped piece of
tempered steel, having one of its corner's exposed to view. I also provide a flat
metal spring; also, attached to the bottom of the chair by means of screws, bolts
or the like.
f
When a car, carriage or truck is being started, I place the chair upon the rail,
whilst the curved part of the rod or bar is placed under the wheel, the operator
then presses upon the other end of the rod or bar, which tends to press the
spring down, thus causing the corner of the dovetailed piece of tempered steel to
grip the rail; and, so prevents the chair from slipping backwards.

COMPLETE SPECIFICATION.
Improvements in Shunting Levers for Railway and Tramway
Vehicles.
I, ELIND JEDUTHAM KNAPP, of 103 Euston Road, London, N.W., Gentleman,
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 improved means for starting railway and tramway cars,
carriages or trucks.
And in order that my invention may be the better understood, I have appended
the accompanying sheet of drawings in which Figure 1 is a side view of my
improved device and Figure 2 is a view showing my improved device applied to
the wheel of a railway truck. Like letters of reference indicate corresponding
parts throughout the several views.
Now in accordance with my invention I employ a rod or bar of iron, steel, or
any other suitable metal a having one end of same slightly curved, said bar is
attached by means of bolts, nuts &c. h to a triangular shaped piece of metal b
hereinafter termed the "chair" provided with two or more lugs e on each side so
as to prevent same from slipping sideways off the rail.
Upon the bottom of said chair is dovetailed or otherwise secured a triangular
or like shaped piece of tempered steel c having one of its corners slightly pro-
jecting; also, I secure to the bottom of the chair b by means of bolts, screws, or
[Primed

page_text: the like a piece of flat steel or like springy metal d. to serve as a spring for giving
the chair a more even leverage.
When a car, carriage, or truck is being started, the chair 6 is first placed upon
the rail, the operator then raises the handle a. and places the curved portion of
same underneath the wheel of the car &c. as shown Figure 1, then the handle a is
depressed when the strain upon the chair b. tends to press the flat metal spring d.
up to the level of the bottom of the chair and thus causing the triangular strip of
tempered steel e to grip the rail, which prevents the chair from slipping either
forward or backward.
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 improved means for starting railway and tramway cars, carriages, or trucks
as and for the purposes herein act forth.
Dated this 31st day of May 1893.
