I, THOMAS REDMAN of 172, Manningham Lane, Bradford, in the County of
Yorkshire, Mechanical Engineer do hereby declare the nature of this invention to be
as follows:-
This invention relates to that part of a Bicycle, Tricycle or Tandem known as the
crank axle bearings, and the object to be attained is to prevent the undue wear
in the said crank axle bearings taking place all in one or two parts of the bearing
cases.
As at present arranged these bearing barrels or cases are a fixture on the frame
of the machines, and in consequence of this and the manner in which the power
is transmitted from the said crank axles to the hub, boss or axles of the driving wheels
most of the wear takes place more or less all in one particular place in bearing case,
there been two bearings in each barrel or case one at each side or end, thus preventing
that exactness of adjustment desired when worn and causing the axle to be out of truc
line in connection with the other parts of the Machine with which it works.
To overcome this I make in the first instance an outer case or carrier somewhat
similar to those at present employed and wherein is fixed the bearing barrel or case,
but instead of been all one continuous ring of metal and the bearing barrel or case
fixed therein permanently, I make it in two halves thus enabling it to be adjusted in
a circular direction at will, and securely joins the same with screws or bolts passing
through flanges of a suitable nature.
Another method is to provide the ordinary outer bearing carrier with a pap or paps
at a suitable place or places for inserting therein a setscrew for fixing, binding and
holding the bearing barrel or case untill released again for adjustment in a circular
direction at will.
In another I provide the ordinary outer bearing carrier with a stout lug or Hange
and then cut or saw this lug or flange and this side of the ring of metal forming the
outer bearing carrier and which then is converted into what is known as a clip or
clamp and by means of a screw or bolt through the lugs or flanges this clip or clamp
is tightened up after receiving the bearing barrel or case and there it is held firmly
untill again released for the purpose of adjusting.

page_text: I, THOMAS REDMAN of 172, Manningham Lane, Bradford, in the County of York-
shire, Mechanical Engineer, 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 that part of a Bicycle, Tricycle or Tandem known as the
crank axle bearings, and the object to be attained is to prevent the undue wear
in the said crank axle bearings taking place all in one or two parts of the bearing
cases.
As at present arranged these bearing barrels or cases are a fixture on the framework
of the machines, and in consequence of this and the manner in which the power is
transmitted from those said crank axles to the hub, boss or axles of the driving wheels
most of the wear takes place more or less all in one particular place in each bearing
case, there been two bearings in each barrel or case one at each side or end, thus
preventing that exactness of adjustment desired when worn and causing the axle to be
out of true line in connection with the other parts of the Machines with which it works.
To overcome this I make in the first instance an outer case or carrier somewhat similar
to those at present employed and wherein is fixed the bearing barrel or case (but
instead of being all one continuous ring of metal and the bearing barrel or case) fixed
therein permanently I make it in two halves, and securely joins the same with screws
or bolts passing through flanges of a suitable nature thus enabling the said bearing
barrel or case to be adjusted in a circular direction on releasing the screws or bolts,
and a new or unworn surface brought to that particular part where most of the wear
takes place in the said bearing barrel or case. This arrangement also allows the said
crank axle bearing to be removed or taken away from the machine bodily, easily and
at will for the purpose of repairs examination or cleaning. The whole being fitted in
a suitable manner and as shown in Figs. 1 and 1ª. In another 1 provide the ordinary
outer bearing carrier with a stout lug or flange (and then cut or saw through this lug
or flange) and this side of the ring of metal forming the outer bearing carrier and
which is then converted into what is known as a clip or clamp and by means of a
screw or bolt through the lugs or flanges this clip or clamp is tightened up after
receiving the bearing barrel or case and there it is held firmly untill again released
for the purpose of adjusting and as seen in Fig. 2.
Another method is to provide the ordinary outer bearing carrier with a pap or paps
at suitable places for inserting therein setscrews for fixing binding and holding the
bearing barrel or case untill released for adjustment.
And in order that my said invention may be most fully and clearly understood and
readily carried into effect, I will now proceed to describe the drawings hereunto
attached.

page_text: Fig. 2 is a modified form.
Fig. 3 is another modification.
Fig. 1 and 1, A is the outer crank axle bearing carrier which is in halves at the
joint J and herein afterwards known and referred to as the bearing carrier and the
dotted lines shows the outline of an ordinary bearing barrel or case and which barrel
or case passes through the hearing carrier as shown and is held there by means of the
screw or bolts B binding together each half by passing through the flanges F, and to
these bolts the stays, trussing rods or tubes T are fixed and best seen in Fig. 1.
X is the part for fixing permanently into the frame work of the machine, but is
not new.
Fig. 3 is another method adapted upon the ordinary form of bearing_carrier at
present in use but in this case I provide the carrier with a extra pap or paps L and pass
through the said pap or paps setscrews S. which binds or presses against the bearing
barrel or case as shown and described.
Fig. 2 is similar to the ordinary bearing carrier at present in use with the exception
that I provide it with the lugs or flanges F, slit C, through the said lugs or flanges
and ring of metal and setscrews or bolts B the pap K is for attaching thereto the
stay rod or rods, but is not now, the dotted line show the outline of bearing barrel
or case.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
(1) The whole of the new part for carrying into effect this invention for improve-
ments in Velocipedes in equalizing the wear and tear in the crank axle bearings
substantially and for the purpose herein shown and described.
(2) The Body or carrier A in combination with joints J screws or bolts B and
flanges F as shown in Fig. 1 and 1*.
(3) The Body or carrier A in combination with lugs or flanges F setscrews or bolts B
and slit (as shown in Fig. 2.
(4) The Body or carrier A in combination with pap or paps L and setscrews B as
shown in Fig. 3.
