PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Axle-caps for Perambulators
or other Vehicles.
We GEORGE MOORE, Senior, ARTHUR LIONEL STAMPS, and GEORGE MOORE, Junior,
all of Priory Works, Aston, Birmingham, in the county of Warwick, Brassfounders
do hereby declare the nature of this invention to be as follows :-
This invention relates to improvements in the manufacture of axle end caps, for
perambulators or other vehicles; and its object is to provide the combination of an
internal base of cast or wrought iron, with an outer shell or covering of sheet metal,
generally of brass.
As at present made, these articles are generally of cast or wrought brass, but if of
the former, they are expensive, and hence they are occasionally made of the latter, in
which case they are necessarily frail, and easily dented or marked, by reason of their
exposed position when in use; and in either case, when a screw thread is used inside
them for attachment, such screw thread is not near equal in wear, to that of an iron
screw thread. In this our invention however, we combine all the increased strength
and firmness, and cheapness of iron, with the outward appearance of a superior
noncorrosive metal, which further, cannot be dented, as those of present make.
In constructing these caps, we first cast or stamp the said cap in iron, (generally
the former;) in the required shape. In such cases where an internal screw thread is
required, or where any other method of fastening is provided upon the said iron body,
it is now done.
We then take a blank of thin sheet metal, and with suitable tools, dish or stamp it,
by two or more operations, to the exterior shape of the iron cap.
press,
The said iron cap is then placed within the shell, and by tools either in a lathe or
the edge of the metal is turned over, firmly uniting the two parts together.
Such other finishing operations of cleaning, polishing &c., are then followed as may
be necessary for their completion.

Improvements in the Manufacture of Axle-caps for Perambulators
or other Vehicles.
We, GEORGE MOORE, Senior, ARTHUR LIONEL STAMPS, and GEORGE MOORE, Junior,
all of Priory Works, Aston, Birmingham, in the county of Warwick, Brassfounders,
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 improvements in the manufacture of axle end caps, for
perambulators or other vehicles; and its object is to provide the combination of an
internal base of cast or wrought iron, with an outer shell or covering of sheet metal,
generally of brass.
As at present made, these articles are generally of cast or wronght brass, but if of
the former, they are expensive, and hence they are occasionally made of the latter, in
which case they are necessarily frail, and easily dented or marked, by reason of their
exposed position when in use; and in either case, when a screwthread is used inside
them for attachment, such screwtbread is not near equal in wear, to that of an iron
screwthread. In this our invention however, we combine all the increased strength

page_text: and firmness, and cheapness of iron, with the outward appearance of a superior
noncorrosive metal, which further cannot be dented, as those of present make.
We will now proceed to more particularly describe and ascertain the nature of this
our invention, by the aid of the accompanying illustrative sheet of drawings, upon
which are figures and letters of reference, and in which :-
Fig. 1, is an elevation, and Fig. 2 a section of the cast iron base.
Fig. 3 shows the blank from which the metallic mount may be made.
Fig. 4, shows the blank stamped by 'a first process, to somewhat the shape of the
casting.
Fig: 5, shows the mount stamped ready to receive the casting.
Fig. 6, shows the casting inserted into the mount, and the upper edges of the latter
turned or closed over.
Fig. 7, shows a metallic lining or covering for the inside of the casting.
Fig. 8, shows a casting thus covered inside and outside.
Similar letters refer throughout the several views to the same thing or part.
In constructing these caps, we first cast the said cap a, in iron, in the required
shape. In such cases where an internal screwthread. b, is required, or where any
other method of fastening is provided upon the said iron body, it is now done.
We then take a blank c, of thin sheet, metal, and with suitable tools, dish or stamp
it, by two or more operations, to the exterior shape of the iron cap, as seen in
Figs. 4 & 5.
W.
The said iron cap is then placed within the shell d, and by tools either in a lathe or
press, the upper edge of the metal is turned over, firmly uniting the two parts
together, as seen in Fig. 6.
In some instances, we may cover the inside of the cap in a similar manner, by
forming an inner lining e, from a blank similarly as described for the making of the
shell d.
This inner shell is first placed within the cap a, then the cap a, is placed
within the shell d, when the upper edges of the latter are closed down, firmly securing
the three parts together as seen in Fig. 8.
As will be readily seen by making these axle caps in this manner, they may be
made of a more or less ornamental character, yet in a very cheap and strong form,
the casting moulds, and the stamping dies being made to correspond; as further, the
metal mounts requiring less finishing than if cast ornamental.
Such other finishing operations of cleaning, polishing &c., are then followed as may
be necessary for their completion.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1st. In an axle cap for perambulators or other similar vehicles, the combination
with an iron base, of a metallic outer shell or covering, substantially as described and
illustrated upon the drawings.
2nd. In an axle cap for perambulators, the combination with an iron base of an
internal and external metallic shell, substantially as described and illustrated upon the
drawings.
