I, CHARLES TWIGG of Potter's Hill Aston in the County of Warwick, Stamper,
Piercer, and press tool Maker do hereby declare the nature of the said inventions for
IMPROVEMENTS IN THE MANUFACTURE OF PULLEY FRAMES, PULLEY. WHEELS, GAS
GLOBE HOLDERS AND OTHER WHEELS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
My Inventions consist of fastening together several pieces of sheet metal to one
centre without soldering, or brazing, and in fastening the centre to an outside rim
also without soldering or brazing.
My invention is applicable to pulley frames with two or more double arms.
And to wheels with three or more spokes.
Figure 7. shows in perspective and Figure 9 in side elevation, a pulley frame
with three double arms made according to my invention.
Figure 8. shows in plan and Figure 10 in side elevation a comet holder made
according to my invention. Design of arms G is not new This or other designs
may be used.
Figure 19. shows in perspective a wheel with four spokes made according to my
invention.
In applying to a pulley frame my invention consists, of a round blank of sheet
metal cut out and pierced with a round hole E in the centre by means of the press,
as shown by Figure L.
.

A strip of sheet metal a little more than double the length of one arm of a
pulley frame as shown by Figure 2 with two horns or projections in the centre A. A.
The strips of sheet metal Figure 2 are then taken and bent at A A forming two
paralel arms of equal length as shown by Figure 4. B. B.
And by means of the press the horns A, A, are hollowed as shown by Figure 6
to form a section of a circle, two or more of these forming the centre hole D
Figure 7.
Two of the blanks Figure 1, and two or more of the paralel arms Figure 4, are
then taken, and the horns or projections A A are placed in the centre hole E
Figure 1 one blank on each side as shown Figure 9.
And by means of the press the horns or projections A. A are then expanded or
rivetted over forming a compact and secure centre.
A comet holder is made by my invention in the same manner as before described
in the pulley frame.
In this instance, instead of the strips of sheet metal Figure 2 in pulley frame,-
An ornamental blank of sheet metal is cut a little more than the length of one
arm of a comet holder with two horns or projections cut at one end as shown by
Figure 3. AA.

page_text: Two of the blanks Figure 1, and three of the ornamental blanks Figure 3, (after
the horns or projections have been shaped to form a section of a circle as described
for pulley frame) and shown Fig. 5 are then taken, and the horns or projections
placed in hole E of round blank Figure 1 one blank at top and one blank at the
bottom,- -as shown Fig. 10.
The horns or projections are then expanded or rivetted over by means of the
press as before explained for pulley frame.
My invention is applied to the centre of a wheel in the same manner as as before
described for a pulley frame and comet holder.
For a wheel of four or any even number of spokes. The strips of sheet metal
are cut double the length of one spoke of a wheel with two horns or projections A A
in the middle Figure 11. and hollowed at each end H H.
Figure 12 shows same after being bent.
For a wheel of three or any odd number of spokes, the strips of sheet metal are
cut the length of one spoke of a wheel with two horns or projections at one
end A A Figure 13 and hollowed or cut out at other end H,
Figure 13 A shows same after being bent.
These are then fastened to one centre by means of the round blanks Figure 1
and expanding or rivetting by means of the press as before described for a pulley
frame and comet holder.
Figure 14 shows in side elevation and Fig. 15 in plan the centre of a four spoke
wheel according to my invention.
A circle of sheet metal is then formed by means of the press Figure 10, with a
concave groove on the outer edge K K Figure 17.
The finished centre Fig. 14 and 15 is then taken and placed inside circle Fig. 16.
The hollows at ends of spokes H H being placed against the convex portion of
groove K K Fig. 17. As shown by Fig. 18.
And by means of the press the sides of groove K Fig. 20 are forced together,
and forceing the convex portion of groove into the hollows H H of centre Figs. 14
and 15.
The centre is now firmly and securely fastened in, forming a solid and perfectly
true wheel.
Figures 1, 2, 4 and 6 show the parts of a pulley frame. Figures 7 and 9 a
complete one Figures 1, 3, and 5, parts of a comet holder Figs. 8 & 10 a
complete one. Figs. 1, 11, 12, 13, 13, 14, 15, 16, 17, 18, 20, parts of a wheel,
Figure 19 a complete one.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
First. The blanks Figure 1.
Secondly. The horns A A. Figures. 2, 3, 11, & 13.
Thirdly. The expanding or rivetting over of the horns A A in hole E of blank
Figure 1.
Fourthly. The hollows H H Figures 11 & 13.
Fifthly. The forceing of convex portion of groove K Figures 17 and 20 into
hollows H H Figure 14.
As herein before described and illustrated in figures 1 to 20 both inclusive of
accompanying drawings.
