PROVISIONAL SPECIFICATION.
Appliances for Securing Collets, Nuts, and Cottár Pins in Place on
Axles.
1 EBENEZER PARTRIDGE of Poplar Avenue, Edgbaston, Birmingham, Founder
and Manufacturer do hereby declare the nature of my said invention to be as
follows:-
This invention relates to novel means or appliances for securing or locking an
ordinary vertically placed split cottar pin in an axle end and a staple shaped appliance
fitting over the adjustable nut and into the collot, said staple shaped appliance having
a turn button or swivel plate to cover the head of the cottar pin to prevent it jumping
or becoming loose during the motion of the vehicle to which such appliances are
fitted.
The part of the staple shaped appliance over where the swivel plate can be moved
is indented for the reception of the head of the cottar pin the stem passing through
a hole corresponding to the vertical hole in the axlo end.
Instead of using the staple shaped appliance with the split cottar pin I can link a
spring ring to the loop of the cottar pin and from the shape of spring ring it can,
when sprung over to embrace the axle end have the lower part or legs of the cottar
pin spread open to confine it in place, the spring ring having a notch and recessed
sides into which the legs engage.

COMPLETE SPECIFICATION.
Appliances for Securing Collets, Nuts, and Cottar Pins in Place on
Axles.
I EBENEZER PARTRIDGE, forinerly at Poplar Avenue but now of Melville Road
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 :-
This invention relates to novel means or appliances for securing or locking an
ordinary vertically placed split cottar pin in an axle end and a staple shaped
appliance fitting over the adjustable nut and into the collet, said staple shaped
appliance having a turn button, or swivel plate to cover the head of the cottar pin
to prevent it jumping or becoming loose during the motion of the vehicle to which
such appliances are fitted.
The part of the staple shaped appliance, over where the swivel plate can be moved,
is indented for the reception of the head of the cottar pin, the stem passing through a
hole corresponding to the vertical hole in the axle end.
Instead of using the staple shaped appliance with the split cottar pin, I can link
a spring ring to the loop of the cottar pin, and from the shape of spring ring it can,
when sprung over to embrace the axle end, have the lower part or legs of the cottar
pin spread open to confine it in place, the spring ring having a notch and recessed
sides, into which the legs engage.
The several Figures on the annexed drawing show my invention.
Figure 1 a plan and Figure 2 an end view, show the appliance consisting of two
| legs A, A, having a depressed end B with a hole through it and provided with an

page_text: indented swivel plate C. The legs A, or there may be one leg only, take into
longitudinal holes D, D, in the collet E, said holes may be like recesses as seen at
Figure 3. The collet has a hood F in which the holes or recesses are also formed.
The legs A, A, are passed through notches formed in a rim or flange G of a nut H, said
nut H and collet E being adjustable on the axle I in the usual manner and is then
securely locked by the key and cottar appliance as herein described and shown at
Figures 1 and 2 by C, B, and J when adjusted for taking up the wear of the leather
washer and collet.
The end of the axle has the usual vertical hole for the reception of the split cottar
pin J, this being first passed through the hole in the head B of the legged appliance.
The indented swivel plate C is then moved over the loop of the split cottar to prevent
it jumping or becoming louse, in other words, locking the split cottar and key in place
as an additional security to that afforded by the lower ends of the split cottar pin being
spread open.
This swivel plate C may work on an ordinary swivel pin, or a screw L
can be turned by an ordinary screw driver to fix the plate down upon the head of the
split cottar.
The depressed end B may be so shaped as to encircle the end of the axle, as indicated
at Figures 4 and 5, the ring K being in a piece with the legs A, A, and having holes
in it, which coincide with the vertical hole in the axle end, so that when the cottar
pin is pushed through them, the swivel plate C can be turned to press upon the head
of the cottar pin and then by screwing home the screw L fixes the swivel plate C
firmly in contact. This ring and leg appliance is shown detached at Figure 6.
As another means of locking the cottar pin J in position, I use a steel spring ring M,
as at Figure 7, to be sprung over and encircle the end of the axle after the cottar pin
has been passed through the vertical hole in the axle end, the ring being looped to the
cottar pin J to constitute a single article.
The lower part of the ring M is provided with a notch and said notch has two side
openings, as seen at Figure 7, into which the ends of the split cottar pin, when split
open, engage and thereby lock the ring M firmly in place.
The steel ring M and its coupled cottar pin may be used with ordinary forms of
Collinge pattern axle appliances when two nuts are used, the collet being adjusted by
the screwing up of such nuts.
I may, if desired, loop a catch N to the swivel plate C as indicated at Figures 8, 9
and 10, so that when the plate C is brought over the head of the cottar pin, the catch N
can be folded down for its tongue piece P to be forced into the eye of the cottar pin
to hold the swivel plate in position over the cottar head. I make the tongue P of this
looped catch of such shape that it bites against the inner edge of the eye of the cottar
pin and forces the head of the cottar pin into close contact with the swivel plate C.
The swivel plate in such case may be rather loosely fitted to the neck of the legged
appliance, so as to be easily turned when the tongue P is drawn out of the eye of
the cottar pin.
The shoulder portion Q of the appliance shown in Figures 8, 9, and 10 is shaped
like a saddle to rest upon the axle end but it may be of ring form, as at Figures 4, 5
and 6 for encircling the axle end.
Having now particularly described and ascertained the naturo of this
invention and in what manner the same is to be performed I declare that what
1 claim is
1. The depressed end B to a forked or single legged appliance A, or with the
depressed end continued as a ring K for encircling the end of axle I having a hole
through either of them for receiving the cottar pin J and rigidly fixing it with the
cottar pin and also for securing the nut Hand collet E of a carriage axle after
.adjustment, as set forth.
2. Arranging a swivel indented plate C on the appliance A for covering and locking
the loop end of a cottar pin J in place, as described and as shown in the annexed
drawings

page_text: 3. The ring M with notched lower portion and side recesses, when said ring and
pin are employed for locking each other in position (when affixed on the end of an
axle), as described and as shown in the annexed drawings.
