PROVISIONAL SPECIFICATION.
Improved Means for Rolling or Shaping Strips of Metal, the
said Means being Specially Designed for the Manufacture of
Clog-irons.
We, JOHN SMITH of Keighley in the County of York, Engineer, and
JOSEPH ROBERTS and JOHN ROBERTS both of Silsden near Keighley afore-
said, Clog-iron Manufacturers, do hereby declare the nature of this invention to be
as follows, that is to say:-
It relates to improved means for rolling or shaping strips of metal which are
required to be more bulky or thicker at or towards each of their extremities than
in their central or middle parts, the said means being specially designed for the
manufacture of clog-irons.
Our said invention consists of mounting a pair of grooved rollers in contiguity
with each other and in suitable framework, rotary motion being imparted to these
rollers, which are coupled together by gearing, from a prime motor shaft operated
by a driving belt.
The grooves in one roller are made to receive the annular ridges of the other
roller and these ridges on one of the rollers are partly cut away so that as they
rotate they will fill the grooves in the other roller more fully at one part than at
another, by which means as strips of metal are fed to the shallow fitting parts they
pass through without being flattened until the fuller parts of said ridges are moved
into contact with their grooves, when said strips of metal will be drawn or flattened.
By supplementary ridges being formed on the peripheries of the ridges which have
their other parts cut away, a groove or furrow is formed in each of the flattened
parts of the strips of metal operated upon, while by projecting pins being formed in
certain parts of these segmental ridges indents are made in the strips of metal at
the desired places so that by being afterwards punched or pierced through proper
openings are formed for the insertion of nails or other means of attachment.
These projecting pins also serve the purpose of dragging the strips of metal so as
to force them to pass between the rollers.

We, JOHN SMITH of Keighley in the County of York, Engineer, and
JOSEPH ROBERTS and JOHN ROBERTS both of Silsden near Keighley afore-
said Clog-iron Manufacturers, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement, that is to say :-

required to be more bulky or thicker at or towards each of their extremities than

page_text: in their central or middle parts, the said means being especially designed for the
manufacture of clog-irons.
In the following description reference is made by figures and letters to the
accompanying sheets of drawings which are illustrative of our invention and form
part of this Specification, the same letters and figures 'being used to indicate the
same parts in all the several wiews.
Eigs. 1 and 2.are front and end elevations of our improved mechanism.
Fig. 3 is a view of said mechanism.as-seen from above.
Fig. 4 is sectional end elevation of a portion of the machine to show the formation
and relative positions of parts hereinafter described.
Figs. 6 and 7 are drawings in detail showing the rollers.
Figs. 8 and 9 are sectional end views of parts shown by Figs. 6 and 7
respectively.
Figs. 10 and 11 are illustrative (on an enlarged scale) of a strip of 'metal 'as
shaped by our improved mechanism.
Our invention consists of mounting a pair of grooved rollers aand bin contiguity
with each other and in suitable framework c and 7. The pressure springs esbeing
employed for pressing or tending to press the roller a against the roller b,their
strength being sufficient to overcome any force necessary for flattening the strips
of metal as is hereinafter described. Rotary motion is imparted to the rollers a
and b, which are geared by the wheels g.and h so as to move in unison, from the
prime motor shaft k through the gearing wheels and m. The rotary motion of
the shaft k being derived through the driving pulley from any motor as will
readily be understood.
The grooves in the roller bare made to receive the annular ridges a¹ of the
roller a and these ridges a' are cut away at a³ (see Fig. 18) so that as the rollers
rotate these ridges a' will fill the grooves b' more fully at one part than at another,
by which means as strips of metal are 'fed to the shallow fitting part they pass
through without being flattened until the fuller parts a' are moved into the grooves 61
when said strips of metal will be drawn or flattened as is the strip fat the part f
Figs. 10 and 11.
'
By supplementary ridges p being formed on the peripheries of the ridges a!, a
groove or furrow p is formed in each of the flattened parts f¹ of the strip, while
by projecting pins stbeing formed in certain positions on these segmental ridges a',
indents (see Fig. 10) are made in the said strip of metal fat the desired places
as shown so that by being afterwards punched or pierced through, proper openings
are formed for the insertion of nails or other means of attachment.
These pins stalso aid the rollers a and b in the dragging of the strips of metal to
cause same to pass between them.
The ridges and grooves 6' formed on and in the roller a and b are of varied
sizes or dimensions in order that varied sizes of strips of metal may be operated
upon or produced.
The strips of metal when formed into the shape shown by Figs. 10 and 11 are
afterwards finished in the usual and well known manner so as to make them
suitable for attachment to clogs.
The guide rail.t is mounted in front of the roller a.and 6 in order to facilitate the
feeding of the rods of metál thereto, while the rollers and might be placed
at the back of the machine in order to assist the discharging of the strips of metal
when formed.
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 iwe
claim is.
.
1. The combination of the roller 'a 'having ridges and projections 'formed 'as
described, with the roller bhaving grooves forithe recoption of said ridges substan-
Halland for the nummoserenecified

of variable depths or sizes substantially as specified.
3. In a metal rolling machine the employment of a roller having annular and
supplementary ridges and projections in combination with a roller having corre-
sponding grooves substantially as set forth.
4. A metal rolling machine having rollers and means for operating same substan-
tially as specified.
