Improvements in or connected with Machines for Dividing and
Marking the Rims of Velocipede or like Wheels with the Positions
of the Spoke Holes.
We, WILLIAM BEARD LAKE, and EDWARD FRANKLYN ELLIOT, both of Albion
Works, Braintree, in the County of Essex, Engineers, do hereby declare the nature
of this invention. to be as follows;
This invention relates to improvements in or connected with machines for divid-
ing and marking the rims of velocipedes or like wheels with the positions of the
spoke holes and has for its object to obtain a simple and inexpensive instrument
by the aid of which the required marking may be effected with rapidity and
accuracy.
In carrying the invention into effect, a base or foot is employed which is adapted
to be bolted to a table or held in a vice.
In a bearing upon the upper part of this base or foot is fixed a short shaft upon
which is mounted with capability of revolving a triangular shaped casting to which
is fixed by means of screws or rivets a dividing disc provided near to its periphery
with several concentric circles of holes.
In each arm of the triangular casting is fixed a rod so that the three rods radiate
from the short shaft or axis and on each rod is mounted with capability of end-
way movement a clamping jaw which is forced outward by means of a spring
and the several clamping jaws are connected with the arms of a three-armed lever
or it might a disc mounted with capability of turning upon the short shaft at the
back of the triangular casting by which arrangement the clamping jaws are all
coupled and caused to move in unison.
In order to place the rim or felloe in position, the V shaped clamping jaws are
forced inward against the springs the rim or felloe is placed around the same and
the jaws are then released, when the rim will be automatically centralised and
securely held thereby, whilst, in order to prevent the three-armed lever being
brought to a dead centre by the action of the springs, a stop is provided which
limits its movement in one direction.
By this arrangement of parts, the device will automatically adjust itself to rims
of varying diameter without the necessity of alteration.
To the base or foot of the apparatus is fixed a radially extending rod, upon which
is loosely mounted a sleeve or fitting which is provided with a ratchet tooth held
to its work by a spring and adapted to engage the dividing holes of either circle
and the sleeve or fitting is adapted to be moved endwise upon the rod so as to bring
the ratchet tooth into position to register with that circle of holes which has been
for the time being selected and in order to fix the sleeve fitting in the required
position the rod is provided with recesses corresponding in position with the circles
of holes and the sleeve or fitting is furnished with a set screw adapted to engage
either of the said recesses

page_text: The rod is at its end provided with a fitting mounted loosely thereon so that
its position may be adjusted to the size of the rim to be divided and this fitting
is adapted to be fixed with the rod by means of a set screw whilst it is formed with
an offset which carries a stud or axis disposed at right angles to the rod and upon
this axis is mounted a scriber or marking instrument longitudinally slotted to
allow of its moving towards the rim to produce the required mark and away from
the rim whilst the latter is being shifted, as hereinafter described.
If desired, the rim may be fixed with one of the jaws or each of them by means
of a bolt or other clamping device in order to prevent the possibility of its creep-
ing and shifting its position with relation to the jaws.
In operation, the jaws are forced inward whilst the rim is placed in position and
afterwards released, the ratchet tooth is adjusted to engage that circle of holes
which is selected and the fittting carrying the scriber is adjusted to allow of said
instrument being brought into contact with the surface of the rim.
The rim together with the holder and perforated disc is then rotated until the
ratchet tooth has passed from one hole to the next, the scriber is then advanced by
reason of the slot and its point is caused to traverse the surface of the rim trans-
versely thereof, the scriber is then retracted and the holder is turned until the
ratchet tooth engages the next notch and these operations are repeated until the
entire rim is divided or marked in the required manner.
By the means hereinbefore described, a simple and inexpensive instrument is
obtained by the aid of which wheel rims may be accurately divided and marked.

Improvements in or connected with Machines for Dividing and
Marking the Rims of Velocipede or like Wheels with the Positions
of the Spoke Holes.
We, WILLIAM BEARD LAKE and EDWARD FRANKLYN ELLIOT, both of Albion
Works, Braintree, in the County of Essex, Engineers, do hereby declare the nature
of this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement ;--
Our said invention relates to improvements in or connected with machines for
dividing and marking the rims of velocipede or like wheels with the positions of
the spoke holes, and has for its object to obtain a simple and inexpensive instru-
ment by the aid of which the required marking may be effected with rapidity and
accuracy.
In carrying the invention into effect, a base or foot is employed which is adapted
to be bolted to a table or held in a vice.
Fixed with the front part of this base or foot is a short shaft upon which is
mounted with capability of revolving a triangular shaped casting to which is fixed
by means of screws or rivets a dividing disc provided near to its periphery -with
several concentric circles of holes.
In each arm of the triangular casting is fixed a rod so that the three rods
radiate from the short shaft or axis and on each rod is mounted with capability of
endway movement a V or equivalent shaped clamping jaw which is forced outward
by means of a spring and the several clamping jaws are connected with the arms
of a three-armed lever or it might be a disc mounted with capability of turning upon

page_text: the short shaft beyond the triangular casting by which arrangement the clamping
jaws are all coupled and caused to move in unison.
In order to place the rim or felloe in position the V shaped clamping jaws are
forced inward against the springs, the rim or felloe is placed around the same and
the jaws are then released, when the rim will be automatically centralised and
securely held thereby, whilst in order to prevent the three-armed lever being
brought to a dead centre by the action of the springs a stop is provided which
limits its movement in one direction.
By this arrangement of parts, the device will automatically adjust itself to rims
of varying diameter without the necessity of alteration.
To the base or foot of the apparatus is fixed a radially extending rod, upon
which is loosely mounted a sleeve or fitting which is provided with a ratchet tooth
held to its work by a spring and adapted to engage the dividing holes of either
circle and the sleeve or fitting is adapted to be moved endwise upon the rod so as
to bring the ratchet tooth into position to register with that circle of holes which
has been for the time being selected and in order to fix the sleeve or fitting in
the required position the rod is provided with recesses corresponding in position
with the circles of holes and the sleeve or fitting is furnished with a set screw
adapted to engage either of the said recesses.
The rod is at its end provided with a fitting mounted loosely thereon so that its
position may be adjusted to the size of the rim to be divided and this fitting is
adapted to be fixed with the rod by means of a set screw whilst it is formed with
an offset which carries a stud or axis disposed at right angles to the rod and upon
this axis is mounted a scriber or marking instrument longitudinally slotted to
allow of its moving towards the rim to produce the required mark, and away from
the rim whilst the latter is being shifted as hereinafter described.
If desired the rim may be fixed with one of the jaws or cach of them by means
of a bolt or other clamping device in order to prevent the possibility of its creeping
and shifting its position with relation to the jaws.
In operation the jaws are forced inward whilst the rim is placed in position and
afterwards released, the ratchet tooth is adjusted to engage that circle of holes
which is selected and the fitting carrying the scriber is adjusted to allow of said
instrument being brought into contact with the surface of the rim.
The rim together with the holder and perforated disc is then rotated until the
ratchet tooth has passed from one hole to the next, the scriber is then advanced
by reason of the slot and its point is caused to traverse the surface of the rim
transversely thereof, the scriber is then retracted and the holder is turned until
the ratchet tooth engages the next notch and these operations are repeated until
the entire rim is divided or marked in the required manner.
And, in order that the said invention may be more clearly understood and
readily carried into effect, we will proceed, aided by the accompanying drawings,
more fully to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1, is a front elevation of a machine constructed according to the present
invention showing the rim of a wheel in position thereon.
Figure 2, is a rear elevation thereof.
Figure 3, is a side or edge view thereof.
Figure 4, is a plan partly in section of the dividing pawl and co-acting parts.
Figure 5 is a front elevation of parts representing a modification in the means
for marking the rim, and,
Figure 6, is a view taken at right angles to Figure 5.
In the several figures like parts are indicated by similar letters of reference.
Referring to Figures 1 to 4 a, represents the base or foot of the instrument which
is adapted to be fixed to a bench or table or held in a vice in any convenient
nosition either vertical or horizontal but for the purpose of this description it is

page_text: assumed to be fixed to a vertical surface, and it is provided with screw holes a¹
for this purpose.
Fixed with the front part of the base or foot a is a short shaft a, upon which
is mounted with capability of revolving a triangular shaped casting b, at 6', spread
out to form lugs and to these lugs is fixed by means of screws or rivets a dividing
disc c, provided near to its periphery with several concentric circles of holes c¹.
In each arm of the triangular casting b, is fixed a rod 2, so that the three rods b²,
radiate from the shaft or axis a², and on each rod 6 is telescopically mounted with
capability of endway movement by its tubular stem 63, a V-shaped clamping jaw 6',
and one of these clamping jaws is forced outward by means of a spring 65, coiled
around the rod 62 and at one end abutting against the end 61 of the casting b,
and at the other end acting against the inner end of the stem 63 of the jaw b, or
if desired each of said rods 62 might be similarly fitted with a spring 65, and
the stems of the several clamping jaws 64 are by means of links b' connected
with the arms of a three-armed lever 66, or it might be a disc mounted with
capability of turning upon the short shaft a², beyond the triangular casting b, by
which arrangement the whole of the clamping jaws b* are coupled and caused to
move in unison.
In order to place the rim or felloe f in position as shown in the drawings,
the V-shaped clamping jaws bare forced inward upon the rods 62, against the
spring 6, the rim or felloe f is placed around the same and the jaws are then
released, when the rim f will be automatically centralised and securely held there-
by, whilst in order to prevent the three-armed lever 66, being brought to a dead
centre by the action of the spring 65, a stop is provided consisting of a stud or
projection *, carried by the casting b, and which limits the movement of said
casting in one direction.
By the arrangement of parts hereinbefore described, the device will be caused
to automatically adjust itself to rims of varying diameter without the necessity
for alteration.
On the inner or under side of the base or foot a of the apparatus is formed a
lump, which is bored to receive one end of a radially extending rod a³, which
is fixed in position by means of a set screw at, screwing through a corresponding
hole in the lump a*, and upon this radial rod a³,, is loosely mounted with capability
of sliding a sleeve or fitting d which is provided with a ratchet tooth or pawl d',
pivotally carried by the sleeve d, and held to its work by a spring d², and this
ratchet tooth is adapted to engage the dividing holes c of the circle and the
sleeve or fitting d is adapted to be moved endwise upon the rod a³, so as to bring
the ratchet tooth d' into position to register with that circle of holes c', which
has been for the time being selected and in order to fix the sleeve or fitting in the
required position upon the radial rod a³, a set screw is provided which screws
through a tapped hole in the sleeve d, and impinges upon the rod a³.
Or, the rod a might if desired be provided with recesses corresponding in
position with the circles of holes c¹ and adapted to receive the end of the set
screw d³, as will be readily understood.
The rod is at its outer end provided with a fitting e, mounted loosely thercon
so that its position may be adjusted to the size of the rim f, to be divided, and
this fitting c is adapted to be fixed with the rod a by means of a set screw c¹,
whilst it is formed with an offset &, which carries a stud or axis c³, disposed at
right angles to the rod a3 and upon this axis is mounted a scriber or marking
instrument et, formed with a longitudinal slot c therein to allow of its moving
towards the rim f, to produce the required mark, and away from the rim whilst the
latter is being shifted as hereinafter described.
In order that the rim f, may if desired be fixed with one of the jaws b', against
the possibility of its creeping and shifting its position with relation to the jaws 6,
one of said jaws or it might be each of them is formed with a lug 4*, thereon per-
forated to receive a hook bolt 68 which is threaded to receive a fly nut 69, and this
?

page_text: hook bolt by engaging the rim and upon the adjustment of the nut securely fixes
the rim f in position.
In operation the jaws &, are forced inward whilst the rim f is placed in position
and afterwards released, the fitting d is adjusted upon the rod in such manner
that its ratchet tooth d'engages that circle of holes a, which is selected and the
filting e, carrying the scriber or marking instrument is adjusted in position on said
rod, to allow of said marking instrument being brought into contact with the
surface of the rim f.
The rim f, together with the entire holder or chuck is then rotated upon the
axis, until the ratchet tooth d' has passed from one hole to the next in the
same circle of holes of the disc c.
The scriber or marking instrument e, is then advanced by reason of the slot e5,
therein and its point is caused to traverse the surface of the rim f transversely
thereof the scriber or marking instrument e', is then retracted and the entire
holder or chuck is then turned upon its axis until the ratchet tooth d¹, engages
the next notch or hole e', and these operations are repeated until the entire rim
is divided or marked in the usual manner.
In the example given at Figures 5, and 6, a modified device is shown in sub-
stitution of the marking instrument e*,
In this case, the offset e2, is at its ends fitted with a lug 2*, which carries, the
stud or axis e³, said stud being in this case parallel with the offset &, and upon the
axis e, is pivotally mounted a blunt ended finger e, which is pressed down upon
the rim f, by means of a spring e, so that in the rotation of the holder said finger
will traverse the face of the rim f, and in order to produce the required mark, a
sharp instrument is by the operator drawn across the end of the finger which serves
as a ruler travelling in contact with the surface of the rim f.
Although three radially disposed jaws b, are hereinbefore shown and described
as the clamping means it will be understood that two or more than three such
jaws and coacting parts may be so employed but the former is the preferred arrange-
ment.
By the means hereinbefore described, a simple and inexpensive instrument is
obtained by the aid of which wheel rims may be accurately divided and marked.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is;-
1. In a machine for dividing and marking the rims of wheels, a holder or chuck
consisting of an axis, a central casting mounted with capability of revolving
on said
axis, three or other number of jaws or clutches mounted with capability of tele-
scopically sliding upon arms or extensions from said central casting, a spring or
springs for forcing said jaws in an outward direction and means for coupling the
jaws so that they are compelled to work in unison, substantially as herein shown
and described.
2. In a machine for dividing and marking the rims of wheels, a holder or chuck
consisting of an axis, a central casting mounted with capability of revolving on said
axis, three or other number of radial arms or rods fixed with said casting, jaws or
clutches mounted with capability of telescopically sliding upon said radial arms,
a spring or springs for forcing said jaws in an outward direction, a lever or disc
mounted with capability of revolving on said axis, tangential links at one end
pivotally connected with said lever and at the other end similarly connected with
the jaws so as to couple the jaws and compel them to work in unison and a stop
for limiting the movement of the lever, substantially as herein shown and described.
3. In a machine for dividing and marking the rims of wheels, the combination
of a base or foot carrying a stud or axis, a central casting mounted with capability
of revolving on said axis, three or other number of jaws or clutches mounted
with capability of telescopically sliding upon arms or extensions from said central
casting, a spring or springs for forcing the jaws in an outward direction, means for

page_text: coupling the jaws so that they are compelled to work in unison, a dividing disc
fixed with the central casting, a radial rod fixed with the base or foot, a sleeve or
fitting mounted with capability of sliding upon said rod and provided with means
of fixing it in any desired position, a spring tooth or pawl carried by said sleeve
and adapted to engage either circle of divisions in the dividing disc, an adjustable
fitting carried by the upper part of the rod and a marking instrument or ruler
carried by said fitting, substantially as herein shown and described.
