Improvements in Machinery for the Manufacture of Hame Caps.
I THOMAS WILLIAM MILLS, of Crescent Works, Pleck Road, Walsall,
Staffordshire, Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to an improved combination and arrangement of parts of
mechanism constituting a machine for manufacturing what are known in the trade
as hame caps, or as they are sometimes termed hame cases, which consists briefly
speaking, of a grooved metallic piece curved at each end (in opposite directions) to
suit the harness collar, and made from sheet or strip iron or steel:
The object of this invention is to combine and arrange the parts of the machine
in a manner that will facilitate the application of the driving power, and also
produce a more compact and useful machine than has hitherto been done, in which
such hame caps may be made from heated or cold metal.
A inachine embracing these my improvements is constructed after the following
manner: Upon a suitable base or frame is mounted the bottom tools. These tools
generally consist of three in a set, but may be increased or decreased in number if
At their rear end
necessary, and are arranged to lie side by side with each other.
a hinge joint is made, upon which is hinged the top tool, which latter fits upon or
into the bottom tool aforesaid. This hinged joint may be made independent of the
bottom tool, or form an extension of the same. This upper tocl at its front end is
formed into a frame shape, that is, it is carried upward, over and back to the base
so as to form a large opening. Through this opening passes the operating shaft.
Upon this operating shaft, and coinciding with each pair of these aforesaid tools, is
provided a cam. Fixed in the upper part and also in the lower part of these
frames, is a friction roller or other renewable wearing surface, between which
revolve the cam beforementioned, so that as the said cams revolve the top tool is
raised and pressed downwards onto or into the bottom tool. Upon this operating
shaft, (and generally between two of the said pairs of tools) is keyed a spur wheel
into which gears a pinion, which said pinion is further keyed upon a driving shaft.
This driving shaft is carried in suitable bearings behind, below or above the tools,
as may be most convenient, generally behind; and is furnished with driving fast
and loose pulleys.
Adverting to the top tool frame; the said tools may be made in one with the
frame, or may be made separate therefrom, and attachable thereto, so that renewals
may be made from time to time without the expense of a new frame in the same
manner as the bottom tools.

COMPLETE SPECIFICATION.
Improvements in Machinery for the Manufacture of Hame Caps.
I THOMAS WILLIAM MILLS, of Crescent Works, Pleck Road, Walsall,
Staffordshire, 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 :-
This invention relates to an improved combination and arrangement of parts of
mechanism constituting a machine for manufacturing what are known in the trade
[DQ11

page_text: as hame caps, or as they are sometimes termed, hame cases, which consist briefly
speaking of a grooved piece of metal, made from sheet or strip iron or steel, and
curved at each end (in opposite directions) to suit the harness collar.
The object of this invention is to combine and arrange the parts of the machine
in a manner that will facilitate the application of the driving power, and also
produce a more compact and useful machine than has hitherto been done, in which
such hame caps may be made from heated or cold metal.
A machine embracing these my improvements is constructed after the following
manner, and in order to explain it more clearly I have appended hereunto
illustrative sheets of drawings upon which are figures and numbers of reference,
similar nnmbers referring throughout the several views to the same thing or part.
Fig. 1, is a general front elevation of the invention.
Fig. 2, is a general plan view of the invention.
Fig. 3, is an end sectional view on line A-A, and Fig. 4, is an end sectional
view on line B-B, and Fig. 5, an end sectional view on line C-C, each in the
direction of their respective arrows shown.
Fig. 6, is an end view of the machine at D, in the direction of the arrow there
shown.
Fig. 7, is approximately the shape of a hame cap or case shown for description
sake.
Upon a suitable base or frame 1, is mounted the bottom tools 2, 3 & 4. These
tools generally consist of three in a set, but may be increased or decreased in
number if necessary, and are arranged to lie side by side with each other, and
firmly bolted to the frame 1. At their rear end hinge joints 5, 6 & 7, are made,
upon which are hinged the top tools 8, 9 & 10, which latter fits upon or into the
bottom tools aforesaid. These hinged joints may be made independent of the
bottom tools or form an extension of the same. These upper tools at their front
ends are formed into a frame shape, that is, they are carried upward, over, and back
to the base, so as to form a large opening. This is sometimes done in the formation
of the casting as seen in the tool 8, at Fig. 3, but preferably I leave the casting
open at the front, and bind their top and bottom parts 11 and 12, by means of a
wrought iron strap 13 which is bolted or pinned thereto as seen in Figs. 4 and 5.
This facilitates the removal when necessary of the said top tool frames from the
machines, as otherwise it would be necessary first to withdraw the driving shaft 14,
end wise. Each of these pairs of tools 2 and 8, 3 and 9, and 4 and 10, are suitably
shaped according to the work they are intended to perform, as for instance, tools 2
and 8, are arranged to simply gutter the strip (straight); while tools 3 and 9, are
further arranged to produce the curve at 15, see Fig. 7, and again, the tools 4
and 10, are made to produce the greater curve at 16, see Fig. 7. In some instances
I am enabled to produce the guttering of the strip in its full length and also the
curve at 15, with one pair of tools.
As before remarked 14, is the driving shaft. Upon this shaft, and coinciding
with each pair of the aforesaid tools, are secured cams 17, 18 & 19. Fixed in the
upper part and also in the lower part of these frames, are renewable wearing
surfaces 20, and 21, between which revolve the cams before mentioned, (or they
may be substituted by rollers) so that, as the said cams revolve, the top tools are
raised and pressed downwards onto or into their respective bottom tools. Upon
this operating shaft 14, is keyed a spur wheel 22, into which gears a pinion 23,
which said pinion is further keyed upon a primary driving shaft 24. This driving
shaft is carried in suitable bearings behind, below or above the tools, as may be
most convenient, generally behind; and is furnished with driving fast and loose
pulleys 25.
Adverting to the top tool frame; the said tools may be made in one with the
frame, as shown, or they may be made separate therefrom, and bolted thereto, so
that renewals may be made from time to time without the expense of a new frame
in the same manner as the bottom tools.
I am aware that hinged tools of similar make to those illustrated (for the

page_text: purpose of description) have been used for producing hame cases, and therefore I
do not claim such as being new, but,
Having now particularly described and ascertained the nature of this my inven
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
--
1st. The general combination and arrangement of the several parts constituting
this my improved machine for making hame cases as herein described and illustrated
upon the drawings.
2nd. In a machine for making hame cases the combination and arrangement of
parts in which the top tool carrier or frame or frames, is or are operated upon by
eccentrics or cams, carried upon a shaft 14, after the manner described and
illustrated upon the drawings.
