IMPROVED METHOD OF MAKING METAL WHEELS AND TOOTHED RACKS
Year: 1885

page_text: EDWARD PRINCE of 129 Lichfield Street Walsall Staffordshire. Assurance
Superintendent do hereby declare the nature of my invention for IMPROVED
METHOD OF MAKING METAL WHEELS AND TOOTHED RACKS to be as follows:-
My Invention as for its object an improved means of making wheels and
toothed racks and other like articles.
In carrying out my invention I shape my improved tooth rings or wheels from
any suitable metal, by passing a strip or length of plain metal of suitable width
and strength through proper shaped rolls or pressed by proper shaped die,s to form
the said strip or length of metal into a toothed or currugated ring of any width
strength or pitch required.
According to my said Invention to make a wheel-I bend into a ring any
suitable length of the rolled or pressed metal after the teeth have been formed or
shaped by the said rolls or die,s I join together the ends of said metal either
by welding or other suitable means-and schrink on a prepared centre or fasten
aforesaid tooth ring to said centre with either screws-bolts or revits.
arrainged I claim to have made an improved strong and durable wheel.
When so
My Invention further consists in making toothed rings from solid rolled or
previously welded metal rings-by passing said rings through proper shaped rolls
to give the pitch of tooth required or by pressing the said rings under suitable
shaped die,s to form the proper shaped tooth in said rings.
My Invention further consists in an improved make of metal toothed rack I pass
a suitable sized strip or length of metal of the proper strength and width-through
proper shaped rolls or pressed with proper shaped die,s to form a tooth of any
pitch or shape required for a wheel rack.

Improved Method of Making Toothed Wheels and Racks and
other like Articles.
I EDWARD PRINCE of 12 Friargate Preston, Lancashire, Superintendent of
Assurance Agents do hereby declare the nature of my invention for IMPROVED
METHOD OF MAKING TOOTHED WHEELS, RACKS AND OTHER LIKE ARTICLES and in
what manner the same is to be performed, to be particularly described. and
ascertained in and by the following statement to be as follows:-
My Invention has for its object an improved means, of making wheels and
toothed racks and other like articles.
In carrying out my invention, I shape my improved toothed rings or wheels
from any suitable metal, by passing a strip or length of plain metal of suitable
width and strength through proper shaped rolls or pressed by proper shaped die,s,
to form the said strips or lengths of metal into toothed rings of any width strength
or pitch required.
According to my said invention, to make a wheel, I bend into a ring any
suitable length of the rolled or pressed metal after the teeth have been formed or
shaped by the said rolls or die,s, I join together the ends of said metal rings, either
by welding or other suitable means, and shrink the prepared ring on a prepared
center; or fasten aforesaid tooth ring to said center with either, screws, bolts, or
revits, when so arrainged I claim to have made an improved strong and durable
wheel.
My Invention, further consists in making toothed rings from solid rolled or
previously welded metal rings, by passing the said ring through proper shaped
rolls to give the pitch of tooth required, or by pressing the said rings under
suitable shaped die,s, to form the proper shaped tooth in said rings.
My Invention further consists in an improved make of metal toothed racks,
I pass a suitable sized strip or length of metal of the proper strength and width,
through proper shaped rolls or press said strip with proper shaped dies to form a
tooth of any pitch or shape required.
By the use of my invention, wheels, and racks, can be made of more durable
and stronger meterial, for any given weight of metal; than cast metal wheels or
racks.
Further the said racks or rings of teeth can be replaced on there respective
fittings when said teeth are worn or damaged.
Having now perticularly described and ascertianed the nature of my said
invention, and in what manner the same is to be performed, I wish it to be

page_text: understood that I do not limit myself to the precise details herein before described,
as the same may be varied without departing from the nature of my invention, but
I declare that what I claim is,
First.) The making of toothed wheels and toothed racks, by other means than
casting, namely by means of rolls or pressing with die,s.
Second.) Shaping the said teeth to suit the various purposes for which the said
wheels and racks can be applied.
Third.) The general combination and arraingements of the said wheels & Racks,
as herein before described.
