PROVISIONAL SPECIFICATION.
An Improved Construction or Arrangement of Break Appliances
for Road Vehicles.
I, EDMUND HARINGTON MOLYNEUX-SEEL, of Red House Chilworth, Hants, Captain,
"The Kings Liverpool Regiment" do hereby declare the nature of this invention to
be as follows:-
The object of this invention is to so construct or arrange brake appliances for
vehicles in such a manner that all jarring and humming noise is prevented and that a
new brake block can be easily put in place when the old one becomes worn out.
For the purpose of invention, I make a block of india rubber or equivalent
material and into same embed (during the moulding) the heads of two or more
bolts, the ends of which project for the reception of nuts adjustable for securing said
block to an ordinary or other strap.
The sides of the rubber or like block are plain or grooved, into which, spiked,
corrugated or curved inner surface side plates become fixed by other holts set
transversely through said plates, the bolts being partly in recesses formed trans
versely in the rubber and partly in recesses formed in an affixable wood or other
block, the outer face of which acts as the brake. This wooden or other block 19
grooved or fluted on its outer edges for the reception of the corrugated or irregular
faces of the two side plates which are pinched into close contact with the wood and
rubber blocks by the nuts of the transverse bolts so that the wooden block can ho
removed by loosening the transverse bolts for fixing in a fresh block as the old one
becomes worn thus keeping the appliance in position for brake purposes without
additional strain being put upon the handle or foot lever by which the brake is
worked.

"The Kings Liverpool Regiment" 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 my invention is to so construct or arrange brake appliances for road
vehicles in such a manner that all jarring and humming noise is prevented, and a new
brake block may be easily put in place when the old one becomes worn out.
In order that my invention may be the better understood I have appended the
accompanying sheet of drawings in which Figures 1 and 2 are respectively side and
end elevational views of the improved appliance according to my invention;
Figure 3 is a section of same drawn on line A B Figure 1, and Figure 4 a section
on line C D Figure 2. Figures 5 and 6 are respectively plans of the inner faces of
the rubber and wood blocks hereinafter referred to.
In carrying out my invention I provide a block of India Rubber or other suitable
elastic material A in which is embedded (during the process of moulding) the heads
of two or more screw bolts a the ends thereof passing through and projecting beyond
a metal plate B to which the rubber block A is cemented or otherwise secured, said
screw bolts a being employed for securing the appliance to the ordinary or other
attachment. The sides of the block A are preferably grooved, into which grooves
press metal side plates 6 b¹ the inner surfaces thereof being spiked, corrugated or
curved. Through said metal plates ò 61 pass the screw bolts cc which, taking into
transverse grooves or slots d d formed on the inner faces of the block A and wooden
brake block C, bind the whole together, by means of screw nuts, firmly and
securely.
From the foregoing it will be seen that whilst the brake block C may, when worn
out, be easily removed and replaced by a new block, it is firmly and immovably held
in position by the side plates b b¹ and the slots d d¹, and, inasmuch as the India
rubber or other elastic material absorbs much of the vibration created on the
application of the brake, the jarring and humming noise which occurs with brakes
as hitherto usually constructed and employed, is effectually prevented.
In order to compensate for the wear of the brake block I prefer to employ
duplicate nuts e e upon the screws a by means of which the distance of the brake
block from the wheel of the vehicle to which it is adapted may be regulated as
desired without necessitating the alteration or adjustment of the brake levers.

page_text: 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 brake appliance for road vehicles substantially as herein
described and shown in the accompanying drawings.
Second. In the brake appliance referred to in the preceding claim, the adaptation
thereto of a block of India rubber or other suitable resilient material substantially
as and for the purposes herein described and set forth.
Third. In an improved brake appliance the mode of and
securing the brake block C to the block A substantially as
shown.
