I, JOHN MACQUEEN, Engineer of Plymouth Avenue, Longsight, Manchester
in the County of Lancaster, do hereby declare the nature of my Invention for
SILENT TYRES FOR ROAD VEHICLES to be as follows:-
I take ordinary Channel Iron of the necessary width required weaker at the
roots of the sides by preferance, these are bent to a circle welded and shrunk on
the wheel in the ordinary way, The Rubber or other Plastic Material of the
necessary form is then inserted and placed within three rollers, the one to keep the
plastic substance or material in its place the other two are placed one above
the other and are closed or opened by Screws quadrant or gearing, these two rollers
are of the necessary shape to close the side of the channel tyre so as to form a
dovetail groove to retain the rubber.

I JOHN MACQUEEN of Polygon Avenue Ardwick Manchester-late of Plymouth
Avenue Longsight; Manchester do hereby declare the nature of my invention for
IMPROVEMENTS IN THE MANUFACTURE OF SILENT TYRES and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
My invention is a machine for inserting and retaining rubber or other plastic
Material in a grooved tyre for road vehicles which is explained in the accompanying
drawings. Fig. 1 is a front elevation of the machine, I I is the framing of the
machine carrying the quadrant G which quadrant radiates on the centre H this
quadrant is moved by the screw J with the handle F which works in the swivel
nut and the swivel J the nut working in the quadrant G and the swivel working
in the frame I. Lengthening or shortening the distance between the nut P and the
swivel J 2 closes or opens the bowls A & B as one is a fixture on the frame the other
moves with the quadrant G, motion is given to these bowls through the wheel K
shewn in side elevation on figure 2, through the bevils & shafts marked R actuating
a pair of spur wheels marked S, these in turn drive a pair of spur wheels marked T
with the bowls A, B. At the bottom of figure 1 is a frame marked N with a
screw and nut Q attached to a slide marked Q1 carrying the stud M.
The method of working the machine is as follows, the wheel E 1 with the tyre
or open channel shrunk and fixed upon it is placed on the stud M and raised to the
required position with the screw L, the rubber is inserted as shewn at D and the
bowl C keeps the rubber down to the bottom of the tyre E, the bowls A & B are
then closed on the channel by the quadrant G and screw J closing the sides of the
channel in to the dovetail form shewn at E, motion is then given to the wheel K
and the bowls A & B givés motion to the wheel El and closes the tyre all round
on the rubber.
Having now fully described the object of my invention and shewn how the same
may be carried out-I claim as my Invention the insertion of rubber or other
plastic material in an open channel Tyre and closing the sides of the same to the
required dove tail form to retain the rubber by the action of the rollers or bowls as
described.
