I WILLIAM CORTEEN of 41, North Church Street Sheffield in the County of
York Carriage Maker do hereby declare the nature of my invention for "AN
IMPROVED TELESCOPE FORM OF RAILWAY UNDER CARRIAGE TO DIMINISH SHOCKS
OR JERKS to be as follows:-
"
The object of my Invention is to construct an Under Carriage for Railway
work in such form as greatly to diminish the shocks caused by Buffers coming
sharply together and to do this I make or form the ends of my side frame piecos
into iron or steel recesses or chambers into which chambers I then cause my draw
or end Bars to travel according to the power brought to bear against the same-
When the Buffers are forced in up to face or end of the Bushes or guide sockets
(which I secure in the usual manner as in the ordinary or stationary draw bars) the
springs which yield to the power employed force out the Buffers and draw Bars,
when the resistance is discontinued.
By my principle I do not confine myself as to the particular length of spring
that I may employ to gain a smooth action, nor do I tie myself to any length of
bushes or guide sockets, for the longer each bush is, the longer is the slide and the
extra smoothness of travel to be thereby gained.
The accompanying Drawings illustrate the features of my Invention.

to the full length and the springs and other actions worked correspondingly.

page_text: I WILLIAM CORTEEN of 41, North Church Street Sheffield in the County of
York Carriage Maker do hereby declare the nature of my invention for "AN
IMPROVED TELESCOPE FORM OF RAILWAY UNDER-CARRIAGE TO DIMINISH SHOCKS
AND JERKS 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 my Invention, is to construct an Under-Carriage, for Railway work,
in such form as greatly to diminish the shocks caused by Buffers coming sharply
together, and to do this I make or form the ends of my side frame pieces into iron
or steel recesses or chambers, into which chambers I then cause niy draw or en.l
Bars to travel according to the power brought to bear against the same-When
the Buffers are forced in up to face or end of the Bushes or guide-sockets, (which
I secure in the usual manner as in the ordinary or stationary draw Bars), the
springs which yield to the power employed force out the Buffers and draw Bars
when the resistance is discontinued.
By my principle, I do not confine myself as to the particular length of spring
that I may employ to gain a smooth action, nor do I tie myself to any length of
bushes or guide sockets, for the donger each bush is, the longer is the slide and the
extra smoothness of travel to be thereby gained.
The accompanying Drawings illustrate the features of my Invention.
Figure 1 shews the action when the moveable Bar and appliances are pushed in
to the full length, and the springs and other actions worked correspondingly.
Figure 2 shows the construction before the pressure is applied.
Like Letters of reference, where such letters appear, indicate corresponding parts
in tho Drawings.
From the shortest lengths of the side frame pieces, that is to say, the interior of
the iron or steel recesses, I frame in at a suitable distance, for spring actions, the
first framing Bars A, between which the ordinary course of framing can be carried
out the slides are constructed of plates B bolted to the top and the bottom of the
side frame pieces and first stationary Bars A, with flap ends B', the iron or steel
recess plates being made a length corresponding to the length from the outer end of
the bush to the inner face of the Bar C, and the said plates are bent at B³ to act as
checks.
Springs D, act direct with the Buffer movements, and Springs E act direct on
the Bars C, and the spindles or guide Rods F sustain the Springs E, the spindles or
Buffer Rods G, sustaining the Springs D in position.
The parts H, are cushions of any suitable substance, so as to be softer than the
metal employed, and these cushions deaden the sound when the moving parts touch
same, and the cross rods or stays I keep the Carriage frame in one exact guage at
the slides or extensions from first stationary Bars A.
The hooks J, are attached to the Bars C, (having by the pins J' swivel move-
ments acting for straight or curve travelling), and these hooks necessarily slide
backwards and forwards with the Bar C, but the Rods K move to the same extent
and with the like action as the Rods F-The Nuts L, are placed so as to regulate
the forward action of the Springs, the chambers being concealed from sight by
outside shield plates, and M are the nuts or inward aboulders on the spindles already
described Against these nuts M, and the Bars A, the Springs are held in position
for the work required, and so gain the objects described; the plates or frame work N,
being for the purpose of resisting a twist and so as to keep the Carriage firm and
substantial for the work-required.

page_text: The above may be adapted to existing Carriages and Buffers, the Buffer Rods
and Bushes varying in length according to circumstances.
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
First The improved form or construction of Railway Under-Carriago, and
employment of moveable draw-bars or end cross-bars as above described, whereby,
by the sliding together of all the parts according to the power brought. to bear,
after the Buffer Rods strike up to the Bush Heads, the dead or sudden jerks usually
· experienced are avoided or materially diminished.
Second-The immediate self-acting return, or re-adjustment, of the Under-
Carriage when the pressure is taken off.
Third-The general improvements in Railway Under-Carriages as herein
substantially described and set forth.
