1, EBENEZER PARTRIDGE, of Litho Villa, Poplar Avenue, Edgbaston, Birmingham,
Founder and Manufacturer do hereby declare the nature of this invention to be as
follows:-
This invention has for object, certain means or appliances for securing wheels upon
axles of road vehicles also of bicycles, tricycles, and machinery fastenings.
According to existing methods, such as the old Collinge pattern principle for
carriage axles and for affixing wheels on axles, the axle arm is made with the outer
ends of two diameters these being screw threaded in reverse order, viz.; the larger
threaded portion baving a short right handed cut thread for the reception of a nut to
bear against the collet to press the conical face of said collet into contact with a corre-
sponding face on the inside of the box, which box is inserted into and wedged tightly
within the hub of the wheel. The smaller threaded short portion of the axle is
formed with a left handed thread, and when the thin left handed nut fitted thereon is
screwed home it tightens the right handed threaded nut, but the said left handed
threaded nut has no appliance to prevent it from turning back a common linch or
cotter pin only being passed down a vertically formed hole in the extreme end of the
axle and which cotter pin merely keeps the nut from running right off when jarred
loose by the wheels motion.
Now according to my invention, I dispense with the left handed threaded portion
of the axle and also the left hand nut together with the vertical hole in the extreme
end thereof, and instead of making the collet with the usual plain front face for the right
handed nut to press against, I make the said collet with a plain hood projecting from
the upper half face, and for withdrawing the same; 1 drill holes into the lower part of
one or both sides of the front edge of said plain hood, into which I pass a piece of
loose wire or pin, or preferably the wire is bent to correspond with the shape of said
hood, so as to form prongs to drop loosely into the holes on the two lower sides thereof,
so that when the nut is turned back, the said prongs act as a shoulder for rib or

page_text: collar of nut to bear against, whereby accurate adjustinent of the collet is casily
obtained, the said prongs, wire, or pin, is then removed until again required for
readjustment, and preferably I leave the front edge of said hood of a plain shape, or I
form it with a downward looking solid flange, having a half round chamber between
the flange and the front face of the collet for the lodgement of a notched rib or collar
which I make on the periphery of the right hand threaded nut, which nut I make
much longer than heretofore to correspond with the increased length of right handed
screw thread upon the axle.
1 also drill a hole in the upper front face of the flanged or plain hooded collets for
the reception of the longer leg of a staple shaped key, the shorter leg of which key
is shaped with a bulb on its end and is slightly strained so as to spring into a recess
formed in the hood of either of said collets when turned down, the body of the key
bearing upon the top surface of the notched nut and which entirely prevents it working
loose during the running of the vehicle, or other applications to which my invention
may be applied.
The loop of the staple shaped key is permitted to project. slightly beyond the front
face of the nut to enable the key to be turned by a pair of pincers or by hand to
enable the bulb to be lifted from its recess when the key has to be removed for the
adjustment of the wheel and collet as often as required, or for cleaning the axle such
as when the wheel has to be removed for re-oiling.
When the hood of the collet has a plain edge, the nut can be turned back with-
out affecting the collet but if the collet has a solid flanged hood, or preferably the
applied loose pin or bent wire prongs which drop into the two sides of plain hood, the
turning back of the nut would draw the collet with it as aforesaid, it is however
necessary to insert the notched rib of the nut into the recess of solid flanged hood
before placing the collet on the axle but in case of the plain hood collet and applied
bent prong shaped wire or pin, the collet can be placed on flat of axle first without
the nut; making the application more simple, the screwing on of the nut causes the
collet to slide forward on the axle and the required accurate adjustment is obtained
by turning the nut in either direction by use of loose pronged shaped wire aforesaid
or solid flange.
In some cases I provide the under part of the loop of the staple shaped key with
a lip to nip or lodge against the front face of the nut, which prevents the plain collet
sliding away from nut when in use.
It will be understood that the longer leg of the staple shaped key engages into
either of the upper notches of the rib or collar on the nut and serves to lock the nut
fast in conjunction with that obtained from the bulb formed on the shorter leg of
key when sprung into position and loop bearing on the square of the nut.

IEBENEZER PARTRIDGE of Litho Villa, Poplar Avenue, Edgbaston, Birmingham
Founder and Manufacturer do hereby declare the nature of my said 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 for object, certain means or appliances for securing wheels
upon axles of road vehicles also of bicycles, tricycles, and machinery fastenings.
According to existing methods such as the old Collinge pattern principle for
carriage axles and for affixing wheels on axles, the axle arm is made with the outer
ends of two diameters these being screw threaded in reverse order viz. the larger
threaded portion having a short right handed cut thread for the reception of a nut to
bear against the collet to press the conical face of said collet into contact with a
corresponding face on the inside of the box which box is inserted into and wedged
tightly within the hub of the wheel. The smaller threaded short portion of the axle
is formed with a left handed thread, and when the thin left handed nut fitted thereon
is screwed home it tightens the right handed threaded nut, but the left handed
threaded nut has no appliance to prevent it from turning back, a common linch or
cotter pin only being passed down a vertically formed hole in the extreme end of the
axle, which cotter pin merely keeps the nut from running right off when jarred loose
by the wheels motion.
Now according to my invention 1 dispense with the left handed threaded portion
of the axle and also the left hand nut together with the vertical hole in the extreme
end thereof and instead of making the collet with the usual plain front face for the
right handed nut to press against I make the said collet with a plain hood projecting
from the upper half face, and for withdrawing the same I drill holes into the lower
part of one or both sides of the front edge of said plain hood into which I pass a
piece of loose wire or pin or preferably the wire is bent to correspond with the shape
of said hood, so as to form prongs to drop loosely into the holes on the two lower
sides thereof, so that when the nut is turned back the said prongs act as a shoulder
for rib or collar or nut to bear against whereby accurate adjustment of the collet
is easily obtained, the said prong, wire, or pin is then removed until again required
for readjustment. I leave the front edge of said hood of a plain shape or I form it
with a downward looking solid flange having a half round chamber between the
flange and the front face of the collet for the lodgement of a notched rib or collar
which I make on the periphery of the right or left hand threaded nut which nut I
make much longer than heretofore to correspond with the increased length of right
or left handed screw thread upon the axle.
I also drill a hole in the upper front face of the flanged or plain hooded collet for
the reception of the longer leg of a staple shaped key the shorter leg of which key
is shaped with a bulb on its end and is slightly strained so as to spring into a

page_text: recess formed in the hood of either of said collets when turned down, the body
of the key bearing upon the top surface of the notched nut and which entirely
prevents it working loose during the running of the vehicle or other applications to
which my invention may be applied.
The loop of the staple shaped key is permitted to project slightly beyond the front
face of the nut to enable the key to be turned by a pair of pincers or by hand to
enable the bulb to be lifted from its recess when the key has to be removed for the
adjustment of the wheel and collet as often as required, or for cleaning the axle such
as when the wheel has to be removed for re-oiling.
When the hood of the collet has a plain edge, the nut can be turned back without
affecting the collet, but if the collet has a solid flanged hood, or the applied loose pin
or bent wire prongs which drop into the two sides of plain hood the turning back of
the nut would draw the collet with it as aforesaid, it is however necessary to insert
the notched rib of the nut into the recess of solid flanged hood before placing the
collet on the axle but in the case of the plain hooded collet and applied bent prong
shaped wire or pin the collet can be placed on flat of axle first without the nut,
making the application more simple.
The screwing on of the nut causes the collet to slide forward on the axle and the
required accurate adjustment is obtained by turning the nut in either direction by use
of loose pronged shaped wire aforesaid or solid flange.
In some cases I provide the under part of the loop of the staple shaped key with
a lip to nip or lodge against the front face of the nut which prevents the plain collet
sliding away from nut when in use.
It will be understood that the longer leg of the staple shaped key engages into
either of the upper notches of the rib or collar on the nut and serves to lock
the nut fast in conjunction with that obtained from the bulb formed on the
shorter leg of key when sprung into position and loop bearing on the square of
the nut.
My invention will be understood by reference to the annexed drawings.
Figure 1 is a perspective view of a plain hooded collet A, notched rim nut B, a
staple shaped wire C being shown through apertures in the hood D and taking into
a groove E between the notched rim F and the nut B proper so that when the nut B
is turned the collet A will slide along with it.
Figure 2 is an end view of a similar nut and collet but instead of the staple shaped
wire being passed through the holes in the collet I attach a blade G to the bight
of the staple shaped appliance C said blade G being passed through a dovetailed
slot H and engaging in the groove E for a similar purpose to that before described.
The staple shaped appliance Figure 3 has one leg shorter than the other and this
short end has a bulb I which when the appliance C, G is removed the longer leg of C
can be pushed into a hole in the collet under the hood as indicated at Figure 3, the
pin C engaging also in one of the notches of the rim F in which it forms a key to
lock the nut B when said nut and collet has been adjusted on the axle, the blade G
finding a lodgment over the nut and with the bent portion of the pin extending
slightly beyond the face of the nut to enable it to be easily gripped for turning the
shorter leg up or down When the appliance is turned with the short leg downwards
the bulb I is sprung into the dovetailed notch H and by a slight undercut of the
notch the bulb I is held firmly in that position.
Figure 4 shows the appliance without the blade G and with the nut and collet
applied to an axle arm ♫ the end of which has only one screw threaded portion because
only one nut B is used.
Figure 5 shows sufficient of an axle arm J and solid back collar K to enable a
modified arrangement to be understood. In this case the hood D of the collet A has
a depending flange L to engage in the groove E between the notched ribs F and the
nut B so that the collet can be withdrawn or pushed along the axle end when the nut
is turned in either direction without requiring a separate appliance as referred to in
the previous figures but the collet D Figure 4 may have a depending flange such as L
to enable the nut when turned to move the collet along in which case I dispense

page_text: with the two apertures referred to for the insertion of the bent wire as at
Figure also with the blade G shown at Figures 2 and 3 but I use the appli-
ance C for the purpose of locking the nut when the bulb I is sprung into the
notch H.
According to the appliance C shown at Figure 5 the legs of which preferably
I make equal in length as shown by the dotted lines in Figure 6 for passing into
holes made in the combined hood D and collet A and instead of the bulb I being
formed as on the shorter leg key the locking is effected by a pivotted dovetail ond
side catch M shown turned up at Figure 5 and turned down in Figure 6 to take into
the dovetail notch side cut or otherwise in either side of collet in similar manner to
the bulb I before mentioned.
This jointed catch side piece M is applicable to either kinds of appliance C but is
preferable with the one having two legs of the same length as when in a locked
position as at Figure 6 there is no possibility whatever of the appliance C becoming
loose or shaking out during the running of the vehicle to which the axle may be
applied.
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. In connection with a notched rim uut having a groove E when employed with a
plain hood D of collet A the employment of a bent or double legged wire for passing
through apertures in the hood D and engaging in the groove E of the nut B when
the collet has to be adjusted on axle or removed therefrom by the turning of the nut
as described.
2. The blade G as part of the appliance C when said blade is employed for
passing through a dovetail notch H in a plain hood D and engaging in the
groove E between the notched rim F and the nut proper B for the temporary
withdrawal or adjustment of said collet on the nut B being turned upon the axle J
as described.
3. The appliance Chaving one leg shorter than the other, the longer leg to be inserted
into a hole under the hood D and engaging in one of the notches of the rim F the
shorter leg having a bulb upon it capable of being sprung into the side dovetail notch
or bulb H and engaging in another notch of the rim F for locking the nut in position
as described whether said appliance has a blade G upon it or be without one as at
Figure 4.
4. The employment of the appliance C with legs of equal length for insertion into two
holes of the collet and with a jointed catch with dovetail end side piece M as a means
for locking the appliance C in addition to locking the nut B after the collet has been
adjusted on an axle as set forth.
