IMPROVEMENTS IN MACHINERY OR APPARATUS FOR RIVETTING PULLEYS OF WROUGHT IRON STEEL OR OTHER METALS

Machine Maker do hereby declare the nature of my Invention for IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR RIVETTING PULLEYS OF WROUGHT IRON STEEL
OR OTHER METALS, to be as follows:-
The object of my invention is to construct machinery or apparatus for rivetting
wrought iron or steel pulley arms to the rims of same, in a quick and efficient
manner with or without heating.
On an ordinary lathe bed I arrange a saddle carrying a spindle which can be
raised or lowered by means of worm and worm wheels on this spindle are placed
two inverted cones between and on, which the pulleys to be rivetted are placed and
by this means, various sizes of pulleys will fit between the cones, the cones are
held on to the pulleys by screws or other suitable means. The rivetting tool is
carried in a spindle, at right angles to the spindle carrying the pulleys, the other
end of this spindle abuts against a spring, on the driving shaft is a tumbler which
comes in contact with a flange on the tool holder spindle and depresses the same,
thus charging and releasing the spring and giving a succession of blows to the
arms of the pulley presented by the pulley holder, in the meantime the horizontal
spindle or tool holder, is slowly revolving (by means of a second shaft and worm
and worm wheels) thus the blows of the revolving tool fall upon the face of the
pulley arm in changing positions. A second saddle is fixed at the other end of the
Jathe bed carrying a vertical spindle upon which is a cutter wheel for dressing
the rivetted ends of the arms of the pulley, as they come round, the vertical spindle
is driven by gear and bevel wheels, and a second horizontal shaft. An adjustable
vice is attached to the bed for carrying successively the pulley arms, while being
rivetted; the driving pulley is put in and out of gear by a clutch or coupling.

page_text: I ARTHUR CROSSLEY of Albion Works Cleckheaton in the county of York
Machine Maker, do hereby declare the nature of my said Invention for IMPROVE-
⚫MENTS IN MACHINERY OR APPARATUS FOR RIVETTING PULLEYS OF WROUGHT IRON,
STEEL OR OTHER METALS, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:―
My invention relates to an improved pulley and machine for holding and
rivetting the arms of the pulleys to the rims without heating them and afterwards,
dressing off, by means of a rotating cutter, any uneveness or roughness caused by
such rivetting.
The objects of my improvements are:—
To construct pulleys with cast iron or steel bosses, and wrought iron, or steel
arms and rims cheaply and efficiently and to rivet their arms to the rims more
quickly, and efficiently without heating, and to hold any size of pulleys whilst
being rivetted; also to dress off any roughness, on the surface of the pulley which
may be caused by the rivetting, pulleys so made are perfectly true, light, and
durable.

Fig. 4 is a back end elevation of Fig. 1.
A is an ordinary lathe bed on which I arrange a saddle B, carrying a vertical
spindle C, which can be raised or lowered by means of a screw D, worm D¹ and
worm wheel D on this-spindle are placed two cones E, E, the top cone is inverted
between and on these cones, the pulleys to be rivetted are placed and by this arrange-
ment of cones, various sizes of pulleys, will fit between them the cones are held on
to the pulleys by screw and nut F; the rivetting tool G is carried in a spindle H,
at right angles to the spindle C, carrying the pulleys, the other end of this spindle.
abuts against á spring in a spring box K, upon the driving shaft L, is a tumbler M,
which comes in contact with a flange N on the tool holder spindle H which it
depresses and releases, thus charging; and letting off the spring, so causing the
spindle H, carrying the tool, to give a succession of, blows to the ends of the arms
of the pulleys, as they are presented by the pulley holder; a gear wheel P, upon
the driving shaft, gears with a second. gear wheel R, upon a second shaft S, upon
which is a worm S', driving a worm wheel. S², upon the tool holder spindle H,
causes the tool holder to slowly revolve, so that each blow given is full upon the
end of the pulley arm, in a different radiating position so that the rivetting is done
in the most perfect and even manner; an adjustable vice U, is attached to the bed
side, for holding successively each pulley arm, as it is being rivetted, the driving
pulley T, is put in and out of gear by the clutch T¹, operated by the treadle V,
a saddle W, at the other end of the lathe bed carries the spindle W₁, which drives
(by means of gear wheels X and X', shaft W2, bevel wheels X2, and X³) a vertical
spindle Y carrying a rotating cutter Y, which dresses the rivetted ends of the
pulley, as they are presented to it, Z is an adjustable rest for steadying the
arms as they are dressed both the saddle B, and saddle W, are adjustable on
the lathe bed..

page_text: 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
1 The tool holder spindle H, operated by flange N, and tumbler M, slowly
rotating, for rivetting the pulley arms as shewn and describe'l.
2 The combination of the saddle B, vertical spindle C, with adjusting screw D
and cones E, E, for holding the pulleys as shewn and described.
3 The adjustable saddle W, carrying the rotating cutter Y², upon the spindle Y,
for operating upon the pulleys as shewn and described.
Dated this 19th day of August 1834. .
