Improvements in and connected with Brakes for Railway Waggons.
We, SAMUEL PENNEY, of 56, Lomas Street, Edgeley, Railway-porter, HENRY
FISHER, of 122, Chestergate, Foreman Railway-porter, and JAMES POLLITT,
of Post Office, Chestergate, Book-keeper, all of Stockport, in the County of
Chester, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in and connected with brakes for rail-
way waggons.
Hitherto the slackening of the speed or the stopping of goods trains has been
entirely effected by the engine-driver and brakes-man applying their brakes,
whilst before going down steep inclines it is necessary for the engine-driver
to stop the train and the brakes-man to leave his van and pin down the brake
of each individual waggon.
This method of applying the brakes for slackening the speed or stopping a
goods train or when running down inclines in practice has been found in-
sufficient and troublesome and the result of accidents, a great deal of wear and
tear and damage to the rolling stock and goods in transit.
The object of our invention is to overcome the said defects and provide means
whereby the brake of each waggon is automatically brought into operation the
moment the driver applies his brake or when running down an incline.
To this end and according to one form of our invention in case of a double
brake, we suitably extend the upper end of the brake lever secured to the shaft
underneath the waggon and connected by rods to the brake blocks as now
arranged, and to the inner end of the buffer bar we hinge a pawl adapted to
engage and push forward the said lever the moment the buffers receive an
impact and are pushed in and thus bring the brake blocks more or less in action
according to the amount of impact received by the buffers.
To facilitate shunting we employ a cam or lever secured to a shaft adapted to
be turned by a spring or other suitable handle arranged at the side of the waggon
whereby the said pawl can be lifted off the respective lever and thus brought in
or out of action as may be required.

page_text: porter, and JAMES POLLITT, now of 46, Grenville Street, Edgeley (late of Post
Office, Chestergate), Book-keeper, all of Stockport, in the County of Chester, 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 follow-
ing statement:-
This invention relates to improvements in and connected with brakes for rail-
way waggons.
Hitherto the slackening of the speed or the stopping of goods trains has been
entirely effected by the engine-driver and brakes-man applying their brakes,
whilst before going down steep inclines, it has been necessary for the engine-driver
to stop the train and the brakes-man to leave his van and pin down the brake
of each individual waggon.
This method of applying the brakes for slackening the speed or stopping a
goods train or when running down inclines, in practice has been found in-
Sufficient and troublesome and the result of accidents, a great deal of wear and
tear and damage to the rolling stock and goods in transit.
The object of our invention is to overcome the said defects and provide means
whereby the brake of each waggon is automatically brought into operation the
moment the driver applies his brake or when running down an incline.
And in order that our invention may be more fully understood we have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures, Fig. I being a side elevation, Fig. 2
longitudinal section, and Fig. 3 a plan of a railway waggon furnished with a
double brake formed in accordance with our invention. Figs. 4 & 5 are detached
sectional views of the same.
a
In carrying out our invention and referring to the figures generally, accord-
ing to one form and in case of a double brake, we suitably extend the upper end
of one of the brake levers a which as now arranged are secured to the shaft b
underneath the waggon and connected by rods e to the brake blocks d. To the
inner end of one of the buffer bars e we hinge a pawl f, f¹ adapted to engage
and push forward the lever a the moment the buffers el receive an impact and
the bar e moves in, which brings the brake blocks & more or less into action upon
the wheels of the waggon according to the amount of impact received by the
buffers el.
In lieu of forming the pawl f, fl in one solid piece, if deemed necessary to
guard against breakages in the brake which might occur through excessive
impact of the buffers, we may form it in two parts with a spring or cushion f³
between, as shown in the drawing, the front part fl of the pawl being adapted to
slide on a stud f³, see Fig. 2, formed on the back part f and coupled thereto,
say by a pin f* engaging in slots formed therein.
The elasticity of the said spring or cushion is such that the latter remains
rigid during the ordinary impact of the buffers and application of the brake
blocks and becomes compressible or flexible when receiving an excess of impact.
To facilitate shunting we employ a cam or lever g or the like secured to a
shaft adapted to be turned by a spring or other suitable handle i arranged at
the side of the waggon, whereby the pawl f, f¹ can be lifted off the respective
lever and thus brought in or out of action as may be required, see more particu-
larly, Figs. 4 & 5, which show respectively the position of the pawl f, ƒ¹ and cam
or lever
when shunting and when the brake is applied.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what
we claim is:-
"In and connected with brakes for railway waggons."
1st. The combination with the buffer bar e of a pawl f, fi adapted to actuate
the brake lever a and thus apply the brake automatically when the buffers are
subjected to impact, all substantially as and for the purpose set forth.

page_text: 2nd. In combination with the pawl f, f', specified in the preceding claim, a
cam or lever g or the like adapted to bring the said pawl in and out of action
with the brake lever a as may be required, all substantially as and for the pur-
pose set forth.
