page_text: I EBENEZER PARTRIDGE of Litho Villa, Poplar Avenue, Edgbaston, Birmingham,
Founder and Manufacturer, do hereby declare the nature of the said invention to
be as follows: —
The object of this invention is to notch the front inside edge of a back revolving
collar of an axle in such a manner that it can, when screwed up or adjusted in the
axle box, be held or fixed in that position by a cross head or sliding plate which is
fitted to move in a slot on or in the head of the axle box by a screw rod or pin
which can be turned for the purpose or the sliding plate can be released from
contact with the revolving collar to enable it to be removed from the box when
desired.
The notches are all round the front inner edge and as the collar is adjusted to
the wearing away of the leather washers the sliding plate fastens the collar so
adjusted the screw pin being then locked by a cottar fitted transversely.
The sliding plate is governed by the screw rod or pin and the plate caused to
abut against the front face of the revolving collar as well as to enter the notch so
as to lock the collar firmly as a nut.
The revolving collar has one or more annular chambers for oil or other lubricant.
The revolving collar may be arranged permanently on the axle or it may be
removeable in which case I employ a removable segment which can be slid in from
the top edge to suit what is known as solid flat axles.
The back face of the revolving collar may be perforated for the reception of a
stud on the end of the spanner by which the collar may be turned, the spanner
also gripping the periphery of the collar for leverage.

H. GARDNER,
Agent for the said E. Partridge,

page_text: I EBENEZER PARTRIDGE of Litho Villa, 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 this invention, is to notch the front inside edge of a back revolving
collar of an axle in such a manner that it can, when screwed up or adjusted in the
axle box, be held or fixed in that position by a cross head or sliding plate which is
fitted to move in a slot on, or in the head of the axle box by a screw rod or pin
which can be turned for the purpose, or the sliding plate can be released from
contact with the revolving collar to enable it to be removed from the box when
desired.
The notches are all round the front inner edge and as the collar is adjusted to
the wearing away of the leather washers the sliding plate fastens the collar so
adjusted, the screw pin being then locked by a cotter fitted transversely.
The sliding plate is governed by the screw rod or pin and the plate is caused to
abut against the front face of the revolving collar as well as to enter the notch so
as to lock the collar firmly as a nut.
The revolving collar has one or more annular chambers for oil or other lubricant
and it may be arranged permanently on the axle, or it may be removable, in which
case I employ a removable segment which can be slid in from the top edge to suit
what is known as solid flap axles..
The back face of the revolving collar may be perforated for the reception of a
stud on the end of the spanner by which the collar can be turned, the spanner also
gripping the periphery of the collar for leverage.
The invention is particularly applicable for the method of adapting what is
known as Collinge shape solid collar to the old Mail pattern of axle but with
certain parts modified to suit the purpose intended.
The drawing Figure 2 shows a Mail pattern axle A.
The axle box C is of the old Mail pattern shape and is screw threaded at its
back inner end for the reception of my newly invented back collar E which I show
in position at Figure 2 but for more clearness in the perspective view Figure 1.
This collar E which can be attached to the axle box and revolve with the wheel
may be a true circle and be permanently fitted on the axle but with those axles
known as "solid flap" axles a portion F as at Figure 3 of the collar E specially

page_text: shaped may be removed by a sliding action outwards from the edge and be slid
into position after the collar is slipped over the axle so as to make a true ring
shape of said collar E the screw thread on the flanges G, G, coinciding for screwing
into axle box after leather washer is put on.
The ends of the removable piece F at H are rounded and fit in corresponding
specially shaped recesses which tend to lock it in position when pushed home.
This revolving back collar is chambered at I, I, for holding grease for lubricating
the back part of the axle, particularly that part where the flange G abuts against
the back collar B of the axle the front part of B and the axle arm A being
lubricated from the usual oil reservoir J formed in the axle box and a ready oil
supply is kept up by pouring it through screw pin hole V without removing any
other part.
The collar E when turned or screwed up tight against the leather washer K of
the abutting piece or axle collar B is locked in that position by the screw bolt L
Figure 7 which is screwed into the lump M of the axle box C, D.
This screw shown detached at Figure 7 has a groove or recess turned in it to
receive prong shaped claws on sliding plate P, said plate having a guide pin Q
which enters the hole R, Figure 6, this being a back view of the enlarged end D of
the axle box so that when the screw L is turned to the right or left the plate P
and pin Q slide with it. Figure 4 is a modified form (of Figure 7) with raised
ring or collar N which is caused to enter a recess in the sliding plate P Figure 5,
Baid plate having a guide pin Q.
The sliding plate P has a certain amount of play into a recess S and when the
screw bolt is turned in one direction the sliding plate P can enter the space S and
be clear of the projections T, T, of the front inner edge of my newly invented
collar E but when the screw L is turned in the reverse direction such as when the
collar E is screwed up into position or adjusted the sliding plate P is then drawn
outwards and enters one of the notches U (square or rectangular) and locks the
collar E in position so that it cannot shift or possibly jar loose until the sliding
plate P is again pushed or screwed away from the space F.
The head of the screw pin, Figure 7 has a hole through it at right angles for the
insertion of a cotter to prevent it turning back and becoming loose while the wheel
is running, also screw pin V answers same purpose when screwed up on to the
groove cut along screw pin L which groove also carries oil supply to chamber J
in box D.
In Figures 4 and 5 the two pieces L and Q are detached, but I make or groove
a recess into the screw L and pinch the two prong shaped claws or arms on the
sliding plate into said recess or groove to connect the two articles together and if
desired instead of putting a cotter through the head of the screw pin L, I screw
another pin V, Figure 2, through the lump M the point of said screw V engaging
in a longitudinal groove in the screw threaded part of the bolt as seen at Figure 7
which will serve as a passage for leading the oil into the reservoir J when the
pin V is removed or unscrewed two or three turns.
My back revolving collar shown at Figure 1 has holes W in its back face as at
Figure 8 for a stud X of a spanner Z to engage in for unscrewing it or screwing it
up the nose Y of the spanner Z bearing upon the periphery of the collar E for
leverage. The notch a in the spanner serves to turn the screw bolt L and the
mouth b of the spanner fits the oil cap c of the axle box.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim is
1. The back revolving Collinge shaped collar E, grease chamber I, notches U on
the front inner edge, either as a complete collar or with a removable piece as at
Figures 1 and 3 for attachment to the back end D of an axle box C as and for the
purposes described,

page_text: 2. The sliding plate P for locking said front adjustable inner edge notched back
revolving collar E of axle boxes with the recessed or collared screw bolt L for
moving said plate P to and fro as described.
3. Recessing the back face of an axle box that the sliding plate P may be
screwed therein for locking or releasing a back revolving collar, whether of the
construction before referred to or any other back revolving collar which has
notches for inner adjustment as the leather washer wears away or whether used
plain or in connection with any Machine requiring revolving collars having
notches.
