I JAMES CLEMINSON of Dashwood House 9, New Broad Street in the city of
London and County of Middlesex Engineer do bereby declare the nature of this
invention to be as follows:-

This invention has reference to a new and improved method of constructing and
arranging the brake rigging of Railway Tramway and other vehicles.
According to one arrangement I make the brake block carriers with a boss or pro-
jection on one side, but the carriers may have a boss on each side.
According to another arrangement I make the said carriers with a recess on one or
both sides.

To join the carriers and maintain them the proper distance apart I employ a tubular
strut which may be of iron steel or other suitable metal, the ends of which fit on to
the before mentioned bosses or projections or into the recesses in the said carriers.
To keep the carriers tight against the extremities of the tubular stay I employ a
tie rod the ends of which are screwed and passed through the carriers.
Between the stay tube and the said tie rod I employ a strut made of flat or other
suitably shaped metal, one end of the strut is bored slightly smaller than the stay
tube and wben about to be put in its place on the stay it is heated sufficiently to
permit of its passing freely along the tube to its position which is about midway of the
length of the tube, and when in place it is allowed to cool and grip the tube.
Near the opposite end of the strut a hole is provided through which passes the
tie rod which, when tightened up converts the whole brake beam thus formed into a
truss; the strut is prolonged sufficiently at the tie rod end and properly shaped for
joining up to the brake lever.

I, JAMES CLEMINSON of Dashwood House, 9 New Broad Street in the City of
London and County of Middlesex, Engineer 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 :-
This invention has reference to a new and improved method of constructing and
arranging the brake rigging of Railway, Tramway and other vehicles.
The brake block carrier A " is formed with a boss or projection, or in some cases
with a recess
"B" on one or both sides as may he desired, onto or into which fits a
tubular strut C" which joins together the carriers and maintains them the proper
distance apart.
To keep the carrier "A" against the extremities of the tubular strut "C" I employ
a tie rod "D" the ends of which are screwed and passed through the carriers.
دو
The rod "D" is retained in position by means of nuts which bear upon the lugs
or recesses "F" formed upon the carriers "A with their faces at right angles to the
centre lines of the tie rod.
Between the tubular strut "C" and the tie rod "D" I employ a strut "E" made
of flat or other suitably shaped metal, one end of the strut "E" is bored slightly
smaller than the tubular strut "C" and when about to be put in its place on the

page_text: strut "C" it is heated sufficiently to permit of its passing freely along the tube to its
position which is about midway of the length of the tube, and when in place it is
allowed to cool and grip the tube.
Near the opposite end of this strut "E" a hole is provided through which passes
the tie rod "D" which when tightened up converts tho whole brake beam thus formed
into a truss; the strut "E" is prolonged sufficiently at the tie rod end and properly
shaped for joining up to the brake lever.
Fig. 1. is front elevation of the brake beat, and blocks.
Fig: 3. side elevation of brake beam and blocks.
Figs. 4 & 5. enlarged details of arrangement.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,
1. The general combination and arrangement of parts together constituting my
improved arrangement of brake beam substantially as herein described and shown on
the drawings.
