I EBENEZER PARTRIDGE of "Litho," Poplar Avenue, Edgbaston, Birmingham,
Founder and Manufacturer, do hereby declare the nature of my said invention
for "IMPROVED MEANS AND APPARATUS FOR SECURING WHEELS ON THEIR AXLES
WITH MEANS OF ADJUSTING THE SAME FOR WEAR," to be as follows:-
The object of my invention is to so make a collet for an axle that the tightening
nut can be put in connection with the collet so as to form part of same to enable
the nut when turned to force the collet up close to the axle or to withdraw it or
to a leather washer thereon and be held securely by a pin which is passed into
notches of the collet and a hole in the axle.
.
For the purpose of my invention I form a collet with a full half band flange
recessed or grooved for the reception of a head or ring on the nut which is held so
as to form part of said collet when put together yet to serve as a distinct nut
when removed from the collet. The inner face of the nut is notched into which
notches a pin is lodged, said pin also passing through a hole in the axle to prevent
the nut receding or moving from its adjusted position.
The collet periphery is broad and has a chamber for oil which can escape to the
cone of the collet through an aperture provided for it.
I fit a plate on the solid collar and cause a lip thereon to bear against a
shoulder formed round the end of the box to prevent the wheel running off should
the axle break within the box, said plate being secured by a screw pin which also
passes or screws into the solid collar.
This Invention is specially applicable to the "Collinge pattern" axle but is
intended for other axles in which an adjustment is required such as in bicycle and
tricycle axles and in certain parts of machinery, lathes, and the like.

I EBENEZER PARTRIDGE of "Litho" Poplar Avenue, Edgbaston, Birmingham,
Founder and Manufacturer 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 make a collet for an axle that the tightening
nut can be put in connection with the collet so as to form part of same to enable
the nut when turned to withdraw the collet as well as to prevent its working loose
away from the nut after it has been screwed up as required close to the axle or to
a leather washer thereon and be held securely by a pin which is passed into
notebes of the nut and collet and an elongated hole in axle end and which pin
may be plain or modified by prong shape end to drop over elongated flats on sides
of axle ends instead of employing elongated holes.
For the purpose of my invention I form a collet with a full half hand flange.
fixed on or loose as most practicable recessed or grooved for the reception of a bead
or ring on the nut which is held so as to form part of said collet when put together
yet to serve as a distinct nut when removed from the collet. The inner face of the
nut is notched, into which notches and the collet a pin or key is lodged and goes
through the elongated hole in axle end to prevent the nut receding or moving from
its adjusted position or if prong shaped end pin is prefered then it is dropped over
flat sides of axle end instead of elongated hole. The loose half band flange
corresponds to the one of fixed position in shape but is more simple in application
being only just placed over side of nut and collet (after removing pin or key J)
connecting both when collet is required to be withdrawn. The collet periphery is
broad and has a chamber for oil which can escape to the cone of the collet through
an aperture provided for it.
I fit a plate on the solid collar and cause a lip thereon to bear against a sboulder
formed round end of the box to prevent the wheel running off should the axle
break within the box said plate being secured by a screw pin which also passes or
screws into the solid collar when a cotter is inserted in pin to prevent its working
loose.
This invention is specially applicable to the Collinge pattern axles but it is
intended for other axles in which an adjustment is required, such as in bicycles
and tricycles and in certain parts of machinery lathes and the like.
Figure 1 of the annexed drawings is a sectional view of a " Collinge" or carriage
axle and box constructed according to my invention. A is the collet of gun metal
or other suitable material upon the axle B, the tightening nut C being connected
with said collet A by means of the half band flange D the nut C easily withdraws
or forces the collet A close to the axle or to a leather washer E. Figure 2 is a
perspective view of the collet A with half band flange D having a recess or
groove F for the reception of a bead or ring G on the nut C shown in perspective
at Figure 3. The inner face H of the nut C has notches into which and into the

page_text: notch I of the collet A a pin or key J is lodged with either plain or prong shaped
end as shown at Figures 1 and 4, said pin or key J also passing through the
elongated hole in the axle end B (or if prong shape end pin, then over flat sides of
axles end instead of elongated hole) to prevent the nut receding or moving from
its adjusted position. The collet periphery has a chamber K for oil which can
escape to the cone L of the collet through an aperture M provided for it.
Figure 5 shows the plate N on the solid collar P having a lip Q thereon, which
bears against a shoulder R formed round the end of the axle box S, said plate N
being secured by a screw pin T which also passes and screws into the collar P of
the axle, a cotter is then inserted through the head of screw pin T to prevent its
working loose, also oil may be poured in pin hole T for lubrication.
Figure 6 shows a loose collet A¹ which may be used instead of the collet
Figure 2 as found most practicable and which can be withdrawn in conjunction
with the tightening nut when desired by means of the loose half band flange U
shown at Figure 7, (with handle W.) The loose half band flange U is provided
with a pin V to take into the notch I (after first removing pin or key) of the loose
collet and is applied to withdraw the collet by placing it over the rings or flanges
of the said collet and tightening nut C as indicated by Figure 8. The loose half
band flange U can be used without the handle W as most practicable.
Figure 9 shows a modified arrangement of my invention applicable to bicycles,
tricycles, lathes, and other machines having similar axles the same arrangement
may be employed as described with reference to the "Collinge" or carriage axle
or a slight modification thereof. The prong shaped end pin or key may be used
instead of plain pin J and the axle end may be formed with flat sides X, X, for
the prongs to drop over as will be understood by reference to Figures 10 and 11.
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
1. The half band flange shown at Figures 2 and 7 for engaging over and
connecting itself to a ring on the tightening nut and a flange on the collet, whether
such half band flange be fixed on or form part of said collet or loose but capable of
being placed on nut and collet for withdrawing it when required as well as to
prevent its working loose as described; Figure 7 may be modified somewhat in
shape to suit rings on collet A and nut C.
2. Forming the tightening nut with an annular series of notches in the inner
face and employing in connection a double ended locking pin, which may be plain
or prong shaped to go through or over flats on axle end for holding said nut and
collet at the desired part on the axle as described with reference to Figures 1, 3, 4,
8, 9 and 10 of the annexed drawings.
3. The employment of a plate on the solid collar of an axle and the means of
adjusting same as and for the purpose specified.
4. The combination of the foregoing features as shown at Figure 1 and the
modified combinations shown at Figures 8, 9 and 10 of the annexed drawings and
also the provision for lubrication etc.
