COMPLETE SPECIFICATION.
Improvements in the Rims of Wheels.
I, EDWARD WARWICK, of Sheffield Works, Alma Street, Aston in the County
of Warwick, 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 has for its object the making of a rim in such a manner that it
can be mechanically adjusted and set in position ready for securing together by the
process of soldering or brazing, the finished rims made under the several modifica-
tions of this my invention approaching nearer to a continuous parallel width than
rims made under other methods.
I will now proceed to describe with reference to the accompanying drawings the
manner in which my invention is produced and used.
Fig. 1 represents a transverse section of a length or sheet of metal corrugated
on each side and formed with a groove and locking-lip.
Fig. 2 represents in transverse section the sheet Fig. 1 folded into the form of a
wheel rim the locking-lip in position ready to pass into the groove.
Fig. 3 represents the locking-lip and groove formed on the upper side, constituting
the second modification of my invention.
Fig. 4 represents a transverse section similar to Fig. 2 with the locking lip passed
into the groove.
Fig. 5 represents a plan of the transverse section Fig. 4.
Fig. 6 represents in transverse section the sheet Fig. 8 folded into the form of a
wheel rim ready for soldering or brazing in accordance with the third modification
of my invention.
Fig. 7 represents in transverse section an enlarged view of the connecting parts
of rim shewn at Fig. 6.
Fig. 8 represents a transverse section of a length or sheet of metal corrugated
on each side and formed with a lip- and stop-piece.
Fig. 9 represents in transverse section the sheet Fig. 11 folded into the form of
a wheel rim ready for soldering or brazing in accordance with the fourth modification
of my invention."
Fig. 10 represents in transverse section an enlarged view of the connecting parts
of rim shewn at Fig. 9.
Fig. 11 represents a transverse section of a length or sheet of metal corrugated
at each side and formed with a lip and stop-groove.
Fig. 12 represents in transverse section the sheet Fig. 14 folded into the form of
a wheel rim ready for soldering or brazing in accordance with the fifth modification
of my invention.
Fig. 13 represents in transverse section an enlarged view of the connecting parts
of rim shewn at Fig. 12.
Fig. 14 represents a transverse section of a length or sheet of metal corrugated
at each side and formed with a butt-stop-piece.
In carrying out the first modification of my invention I form the corrugations a,
the groove b, and the locking-lip c, by means of rolls, or other suitable tools,
producing a length of material of the transverse section shewn at Fig. 1.
I next bend the part e into the form shewn at f Fig. 2 bending over the corrugated
parts into the position shewn at g Fig. 2.
I next compress the lip h into the groovej until the lip is in the position shewn
at in the groove j¹ as represented at Fig. 4; the providing of the groove as
shewn at 6 Fig. 1, as shewn at j Fig. 2 and as shewn at j Fig. 4 and the providing
E

page_text: of the lip as shewn at c Fig. 1, as shewn at h Fig. 2 and as shewn at h¹ Fig. 4 and
the
combining of the lip within the groove, constitutes the patentable novelty of
the first modification of my invention.
My improved lipped and grooved rims when locked together in the manner
shewn at Fig. 4 would be ready for brazing or soldering without the use of the
tic-wires usually used to support rims during the process of brazing or soldering.
By a second modification of my invention I produce the lip and groove on the
sheet of metal and fold such sheet of metal into the form of a rim with the
locking lip taking into the groove from the underside as shewn in the cut off
section Fig. 3; it will be apparent that tyres used on rims made under this second
modification of my invention would be provided with a peripherical groove to fit
over the projecting bead & formed by the outer surface of the groove.
By a third modification of my invention I produce a length or strip of material
of the transverse section shewn at Fig. 8 producing the corrugations and also
producing the stop piece m and the lip n I next bend the part e¹ into the form
shewn at f Fig. 6, bending over the corrugated side parts into the position shewn
at g' Fig. 6 the lip n, taking an end bearing against the stop piece m, the providing
of the lip and stop to form a joint connection, constituting the patentable novelty
of the third modification of my invention.
By a fourth modification of my invention I provide a length or strip of material
of the transverse section shewn at Fig. 11, producing the corrugations or other
required shapes and also producing the step-lip p and the stop-groove q. I next
bend the part e² into the form shewn at f Fig. 9 the step-lip p taking into the
stop-groove to form a joint connection, constituting the patentable novelty of this
fourth modification of my invention.
By a fifth modification of my invention I produce a length or strip of material
of the transverse section shewn at Fig. 14 or produce any other required shapes,
also producing the butt-stop-piece r, and the butt-end s, I next bend the part e³,
into the form shewn at f³, Fig. 12, the butt end s, taking an end bearing against
the butt-stop-piece the producing of the butt stop-piece r, with its bed-rest t to
receive the ends for the purpose of forming a joint connection, constituting the
patentable novelty of the fifth modification of my invention.
I wish it to be distinctly understood that I do not claim the shape or configuration
of the corrugations shewn at a Fig. 7 as any part of my invention neither do I claim
the outer configuration shewn at f Fig. 2, f' Fig. 6, f' Fig. 9, or f³, Fig. 12, as
parts of my invention such shapes being old.

I also wish it to be distinctly understood that I can produce and utilize any old or
suitable outer configuration of rim in lieu of the outer configuration shewn at f Fig. 2,
ƒ¹ Fig. 6, ƒª Fig. 9, or 3 Fig. 12, and in a like manner I can produce and utilize
any old or suitable inner configuration of rim in lieu of the inner configuration
shewn at Fig. 2, g' Fig. 6, g² Fig. 9 or g³ Fig. 12.
The locking-lip of first modification can be secured within the groove j, by means
of compression between suitable rolls or tools, or the locking lip c can be secured
within the groove by means of soldering or brazing, in either case the wires usually
used when connecting such like rims together during the process of brazing or
soldering will be dispensed with, in a like manner the inverted joint connection of
second modification can be compressed together, or secured by the process of
soldering or brazing, wiring being dispensed with.
.
The joint of third modification can be made by the process of soldering or
brazing, wiring would be required to keep the lip n against the stop-piece m, but
when so wired the rin-tube would be parallel the whole of its length.
The joint of fourth modification can be made by compression or by soldering or
brazing, wiring being advisable when soldering or brazing, nevertheless the rim-
tube would be connected together parallel.
The joint of fifth modification is intended to be made by the process of soldering
or brazing as described in reference to third modification, the rim-tube being secured
together parallel and mechanically true.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1st. The making of a wheel-rim with a locking joint formed by the interlocking
of a lip within a groove as illustrated and described in relation to the first
modification.
2nd. The making of a wheel-rim with a locking joint formed by the interlocking
of a lip within a groove as illustrated and described in reference to the second
modification.
3rd. The making of a wheel-rim with a lapping butt joint as illustrated and
described in relation to the third modification, shewn at Figures 6, 7, and 8.
4th. The making of a wheel-rim with a grooved butt-joint as illustrated and
described in relation to the fourth modification, shewn at Figures 9, 10, and 11.
5th. The making of a wheel-rim with an open butt-joint as illustrated and
described in relation to the 5th modification, shewn at Figures 12, 13, and. 14.
