page_text: LETTERS PATENT to Ebenezer Partridge of "The Lion" Works High Street
Smethwick in the county of Stafford Engineer, Iron Founder and Axle
Manufacturer for an Invention of AN IMPROVEMENT IN THE CONSTRUCTION
OF REVOLVING BACK COLLARS OR CAPS OF AXLES WITH MEANS OF ADAPTING
AND ADJUSTING THEM AND SECURING AXLE BOXES IN POSITION WITHOUT
THE USUAL LONG OR SHORT BOLTS
PROVISIONAL SPECIFICATION left by the said Ebenezer Partridge at
the Office of the Commissioners of Patents on the 4th June 1883.
EBENEZER PARTRIDGE of "The Lion" Works, High Street Smethwick in the
county of Stafford, Engineer, Iron Founder and Axle Manufacturer. AN
IMPROVEMENT IN THE CONSTRUCTION OF REVOLVING BACK COLLARS OR CAPS OF
AXLES WITH MEANS OF ADAPTING AND ADJUSTING THEM AND SECURING AXLE
BOXES IN POSITION WITHOUT THE USUAL LONG OR SHORT BOLTS
The object of this invention is a special construction of revolving back collars
or caps of axles with means of adapting and adjusting them and securing axle
boxes in position without the usual long or short bolts.
For the purpose of my invention I notch score or recess the edge or edges of
screw in collars or caps of mail axles for the reception of the head of a screw pin
whose stem is inserted in a lump or projection provided for it on the head of an
axle box said hole or aperture which the screw pin fits serving also as an oil hole
leading to the interior of the box for lubricating purposes The aperture is closed
when the screw pin is in its place

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Ebenezer Partridge in the Great Seal Patent Office on the
4th December 1883.
EBENEZER PARTRIDGE, of "The Lion Works" High Street, Smethwick, in the
county of Stafford Engineer, Iron Founder, and Axle Manufacturer.
AN
IMPROVEMENT IN THE CONSTRUCTION OF REVOLVING BACK COLLARS OR CAPS OF
AXLES WITH MEANS OF ADAPTING AND ADJUSTING THEM AND SECURING AXLE
BOXES IN POSITION WITHOUT THE USUAL LONG OR SHORT BOLTS
The object of this invention is a special construction of revolving back collars
or caps of axles with means of adapting and adjusting them and securing axle
boxes in position without the usual long or short bolts.
For the purpose of my invention which I clearly show at Figures 1, 2 and 3
in the annexed drawings I notch, score or recess the edge or edges A of the
screw-in collars or caps B of mail or other carriage axles for the purpose of readily
adjusting the axle box in position when required as the leathers wear away and
for the reception of the head of a screw pin C whose stem D is inserted into a
Jump or projection E provided for it on the head F of an axle box G said hole or
aperture which the screw pin fits serving also as on oil hole H leading to the
interior of the box G for lubricating purposes. The aperture is closed when the
screw pin is in its place.
Figure 4 is a modified form of revolving collar with a portion I removed and so
shaped at its edges J J as to fit into corresponding recesses or channels K, K, of
the collar and form a continuation thereof. The space L in the collar corresponds
to the thickness of the axle M so that it can be pushed transversely across it and
then the piece I can be slipped into position to make the collar complete.
This method of making the axle collar is available to axles already made, and
when in position and screwed into the box secures the box and when on the axle
by abutting against the ring N which is part of the axle. The degree of bite is
adjustable to the greatest nicety by simply turning the collar to the right or to
the left as desired as the Leathers wear away and then locking it in that position by
the screw pin which as before stated is screwed into the lump E of the box head F
the shoulder a of the screw D lodging itself in the recess A of the collar B then
in line with it.
The screw pin D has preferably a square head C projecting beyond the collar B
as at Figure 1 to enable it to be turned by the spanner Figures 5 and 6 this
having a square hole bin the shank end P for the purpose. The spanner has a
claw at the shank end to fit any recess A in the edge of the collar B for screwing
up or for unscrewing purposes.
The spanner head R fits the outer cap S as in ordinary coach spanners.
To keep the notches of the collar clear of dirt etc and to give it the exact
appearance of what is known as a Collinge Axle solid collar I cover them with a
band or shield T Figure 7 the inner surface of the outer ring being provided
with lips cc which take into the groove d after being inserted into the notches A
and then turned round a short distance to be secured by head C of the screw pin D
which lodges in the recess e
The shield band Figure 7 corresponds to the collar Figures 1. 2 and 3 and they
are put on the axle before the final welding is effected but the band shown at
Figure 8 corresponds to the collar Figure 4 a tongue or shutter V pivotted at f
serving to complete the cirele when closed to.
I secure the screw pin by a cottar passed through its head but any other
appliance for that purpose can be fitted

page_text: Having now described the nature of my said invention and in what manner the
same is to be performed I declare that I claim.
First The notched periphery revolving and adjustable collar Figures 2 and 3 as
applicable to axle box G Figure 1.
Secondly The notched periphery revolving and adjustable collar Figure 4 made in
two parts as applicable to axle boxes.
Thirdly The internally lipped band shield Figures 7 and 8 and the method of
securing it in position on or to the notched collar B as set forth.
Fourthly I claim The oiling aperture closed by a screw plug or pin whose
shoulder serves as a safety guard to the notched edged collar as set forth
and as shown in the annexed drawings.
In witness whereof I the said Ebenezer Partridge have hereunto set my hand
and seal this First day of December in the year of our Lord One thousand eight
hundred and eighty three
