Year: 1880

page_text: LETTERS PATENT to Richard Russell Gubbins, of 17, Park Road, New Cross,
in the County of Surrey, Gentleman, for an Invention of "IMPROVEMENTS IN
THE MANUFACTURE OF METAL WHEELS AND PULLEYS, AND NEW OR
IMPROVED MACHINERY OR APPARATUS TO BE USED IN SUCH MANUFACTURE."
PROVISIONAL SPECIFICATION left by the said Richard Russell Gubbins
at the Office of the Commissioners of Patents on the 1st November 1880.
RICHARD RUSSELL GUBBINS, of 17, Park Road, New Cross, in the County of
Surrey, Gentleman. "IMPROVEMENTS IN THE MANUFACTURE OF METAL WHEELS
AND PULLEYS, AND NEW OR IMPROVED MACHINERY OR APPARATUS TO BE USED
IN SUCH MANUFACTURE."
This Invention relates to certain improvements in the manufacture of metal
wheels and pulleys, and new or improved machinery or apparatus to be used in
such manufacture, the object being to swage from a centre the ends of the spokes
of the wheel to receive the flange, periphery, or tyre.
In carrying the Invention into practice,-
In the case of ordinary pulleys for transmitting power by belting or friction, in
which usually a central hub or boss receives metal spokes, and in order that such
spokes shall receive truly the flange, periphery, or tyre, I place the boss previously
bored out to the required size on a fixed central pin, stud, or support, and then by
suitable swaging appliances the ends of the arms or spokes are brought successively
to a true radial distance to or from that centre, and then furnished with the lugs
or ears necessary for attaching the rim to them, and in the case of disc or plate
metal wheels the true peripherial surface is obtained by the same means and
appliances. In cases, however, in which cast metal wheels have to be applied to
shafting, axles, or rods already in position, I employ in the making of such wheels
sheet asbestos or talc to divide the parts of the wheel casting in the mould, so that
the divisions or split in such wheels may be secured as is necessary for facility in
fixing the same and preparatorily to the swaging operation.

page_text: The machinery employed for the construction of ordinary wheels where the boss
or hub is made of cast iron and the spokes and rim of wrought iron consists of a
fixed central pin firmly attached to a bed plate whereon slides a suitable pair of
swage blocks for forming, spreading, or shaping the ends of the spokes. By rotating
the boss of the wheel with its attached spokes round the said fixed central pin the
spokes are brought successively to the swage blocks and there formed as required
at a true radial distance from the centre.
The swage blocks above mentioned are capable of being moved along the bed
plate of the machine from or to the centre according to the diameter of the required
wheel and of being fixed in any required position, thereby affording means of
speedily constructing metal wheels of any required diameter.

the said Richard Russell Gubbins in the Great Seal Patent Office on the
30th April 1881.
RICHARD RUSSELL GUBBINS, of 17, Park Road, New Cross, in the County of
Surrey. "IMPROVEMENTS IN THE MANUFACTURE OF METAL WHEELS AND
PULLEYS, AND NEW OR IMPROVED MACHINERY OR APPARATUS TO BE USED IN
SUCH MANUFACTURE."
This Invention relates to certain improvements in the manufacture of metal
wheels and pulleys, and new or improved machinery or apparatus to be used in
such manufacture, the object being to swage from a centre the ends of the spokes
of the wheel to receive the flange, periphery, or tyre.
In carrying the Invention into practice,
In the case of ordinary pulleys for transmitting power by belting or friction, in
which usually a central hub or boss receives metal spokes, and in order that such
spokes shall receive truly the flange, periphery, or tyre, I place the boss previously
bored out to the required size on a fixed central pin, stud, or support, and then by
suitable swageing appliance the ends of the arms or spokes are brought to a radial
distance to or from that centre and thus furnished with the lugs or ears for attaching
the rim to them.
The machinery employed for the construction of such wheels whereof the spokes
and rim are of wrought iron consists of a fixed central pin firmly attached to a
bed plate whereon slides a suitable swage block for forming, spreading, or shaping
the ends of the spokes. By rotating the boss of the wheel with its attached spokes
round the said fixed central pin the spokes are brought successively to the swage
block and there formed at a true radial distance from the centre with the requisite
flattened end or foot.
The swage block above mentioned is capable of being moved along the bed plate
of the machine from or to the centre according to the diameter of the required
wheel, and of being fixed at any required position, thereby affording means of
speedily constructing metal wheels of any required diameter.
In order that the Invention may be well understood I have hereunto annexed a
Sheet of Drawings, wherein is represented apparatus constructed according to this
Invention for the purpose of carrying the same into practical effect.
Fig. 1 is a side view of the apparatus; Fig. 14, sectional half plan of frame at
the working end of the apparatus showing fire box attached.
Fig. 2 is a plan of the balance weight and hook, swage block, and portion of the
bed plate; Fig. 3, plan of balance weight with swage block removed but balance
weight in position.
Figs. 4, 5, and 6 are details of construction of swage block.
A is the bed plate, supported by standards A², A2; B, a block for carrying the
central pin or support C, capable of turning around and for purpose of carrying the
collars C³, shown in dotted lines (for receiving the bored out boss of the wheel of
this or that size); D is a screw working through a nut piece E in block B for
raising the central pin C as and when required for turning the wheel being
wrought; F is a fire box or hearth for heating the ends of the spokes to be wrought
at same time that another spoke is being operated upon to swage the end thereof.
This fire box is fitted with a nozzle, as shown, and is carried upon a saddle shaped
support G, capable of sliding upon the arm H, which is hinged at H' to the
standard A¹; I is a cotter, which, by being passed through and driven up tight in
the slots in arms G¹ of the support G, will hold same with the fire box at required

page_text: distance from and by the hinges H₁ at any required angle to the centre line
of the central pins C to accomodate varying length of spokes to be manipulated.
K is the swage block (details whereof are given below) which slides on the centre
rib A³ of the bed plate A, and is provided with a channel, as hereinafter described,
into which the spoke to be swaged is laid, and for holding the said swage block at
the proper distance for bringing the ends of the spokes to true radial distance from
the centre C the balance weight L is used, having hooked arms M, carrying studs N,
which studs take under the projecting edges A of the bed plate, and the hooks M
of the balance weight engage with studs K¹ of the swage block, so that effectual
counterpoise is secured for the swaging operation. In some cases it may be desireable
to form notches or hollows on the edges of the bed plate A to provide set distance
or resting points for the studs N, or notches or hollows on the rib A³ of bed plate A
for the swage block K, or both.
The swage block, shown in detail Figs. 4, 5, and 6, consists of an upper and lower
piece hinged together at O; these upper and lower pieces form together a die, thus
providing a channel in which the spoke lies and a recess or mould P of the required
depth and shape for the foot of the spoke which is to be formed on the said spoke.
The face of the swage block is curved, as shown at Q, Fig. 4, corresponding to the
curve of the periphery of the wheel to be made, so that the feet or swaged ends
of the spokes formed as described in recess P accurately receive said periphery.
After forging each spoke end the upper portion of the swage block is thrown
back, and the channel of the swage block receives the next spoke, and so on; x, x, is
the line of the spokes under operation.
Having now described the nature and particulars of the said Invention in such
wise that the same may be readily carried into practical effect, I claim,-
Firstly. In the manufacture of metal wheels or pulleys, the swageing of the
spokes from a centre to form the end of such spokes at true radial distance from the
centre to receive the flange, periphery, or tyre, as herein set forth.
Secondly. The apparatus, as herein described, for effecting the swageing of the
wheel spokes, as set forth.
In witness whereof, I, the said Richard Russell Gubbins, have hereunto set
my hand and scal, this Twenty eighth day of April, in the year of our
Lord One thousand eight hundred and eighty-one.
