PROVISIONAL SPECIFICATION.
Linch-pins or Cottars for Preventing Wheels or Rollers from
Coming Off their Axles.
1, ALEXANDER MCQUEEN, of Paisley Villa, 64 Park Road, Plumstead in the
County of London, Engineer, do hereby declare the nature of this invention to be
as follows:-
:-
A linch-pin or cottar to pass through a hole in an axle, and through the pin or
cottar, and round the axle, passes a ring.
I. The pin or cottar may be of any section, preferably rectangular, and its length
straight or curved; a hole being made in the axle to receive it. In the ends of
the "pin" or cottar are holes, a little further apart than the diameter of the axle,
for receiving the "ring."
The "ring" may be of any section, preferably round, it is a complete circle,
slightly larger in diameter than the axle it is to suit, except, that it is cut, having
its two ends butting on each other, the ends being of hemispherical form to
facilitate entering it into the holes in the pin.
It is made of metal, preferably steel, and is elastic, so as to admit of its being
sprung into the holes in the "pin," and still retaining its circular form.
METHOD OF. USING.
"
"
The "pin" is placed into the hole in the axle, provided for it, and the "ring
passed or threaded over the end of the axle; spring the " ring" into and through
one of the holes in the "pin," moving it circumferentially till it meets the opposite
end of the "pin," and into its hole, spring the "ring as before. The "pin" has
then the complete "ring" passing through it; and the "ring" is round the axle ;
the "pin" therefore cannot get out till the "ring" is removed, the wheel or roller

the "pin" & the "wheel," if required, to prevent too much wear on the "pin."
II. The pin is as in I. except, that it is provided with a shoulder or projection so
that it can rest on the top part of the axle and prevent it passing through the hole
in the axle.
The "ring" is as in 1, except, that it is a little larger, and is passed through the
top end of the "pin," a little further from the axle than in I.
METHOD OF USING.
The "pin" is placed in the hole in the axle, the "ring" having been threaded
through it; the "ring" is then opened out and sprung over the end of the axle, its
size being such, that when it is resting against the bottom end of the "pin," and its
ends butting, it shall be close up to the underside of the axle, and thus prevent the
piu" from rising. The end of the axle. should be rounded off at such a distance
from the "pin" as will admit of the above conditions.
