Complete Specification Accepted; 18th May, 1889
I WILLIAM HENRY RHODES of No. 5 Lime Grove Longsight Manchester in the
County of Lancaster Engineer do hereby declare the nature of this Invention to be as
follows:-
The first part of my Invention relates to the mechanism employed for running the
carriage out. It has hitherto been customary to employ for this purpose a train of
toothed gearing driven from the rim shaft.
I propose to dispense with some of the gearing and substitute a rope or band which
will slip under excessive strain.
In carrying out this improvement I employ a pinion on the rim shaft which gears.
into and drives a spur wheel mounted on a stud secured to the frame and on the boss
of this spur wheel is secured a grooved pulley from which the band passes over a guide
pulley to another grooved pulley on the boss of which is secured a pinion the band
returning over a guide pulley to the grooved driving pulley. The pinion driven by
this band gears into and drives a toothed wheel loose on the ordinary back shaft the
toothed wheel being connected to and disengaged from the back shaft by the usual
clutch operated from the cam shaft.
By this arrangement the front roller shaft is placed on the inner side of the front
end of the rim shaft and so the roller shaft and the rim pulley on the rim shaft.
are brought much nearer together thereby economising space beyond the head-
stock.
The front roller shaft may either be driven by spur wheels and a pair of bevels from
the twist wheel on the rim shaft or in other convenient manner.
The second part of my Invention refers to the mechanism described in the
Specification to Letters Patent granted to me on the 8th November 1886 No. 14268
for driving the scroll shaft by which the carriage is driven on the inward run.
In that Specification I described for this purpose a rope or band driven from a
grooved pulley secured to the loose pulley on the rim shaft and adjusted by means of
a weighted tension pulley which presses against it.

page_text: I WILLIAM HENRY RHODES of No. 5 Lime Grove Longsight Manchester in the
County of Lancaster Engineer 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:-
The First part of my invention relates to the mechanism employed for running the
carriage ont. It has hitherto been customary to employ for this purpose a train of
toothed gearing driven from the rim shaft.
I propose to dispense with some of the gearing and substitute a rope or band which
will slip under excessive strain.
And in order that my invention may be fully understood and readily carried into.
effect I will describe the accompanying four Sheets of Drawings reference being had
to the figures and letters marked thereon.
Similar letters refer to similar parts throughout the several views.
Figure 1 is a side view Fig. 2 an end view and Fig. 3 a plan of a mule headstock
to which the First and Second Parts of my invention are applied. Fig. 4 is a detail
view of part of the same.
In these views.-a represents the rim shaft on which is keyed a pinion or twist
wheel a' which gears into a spur wheel b, see Fig. 3 mounted on a stud 6 in a curved
slot in a bracket secured to the frame of the headstock on the boss of the wheel b is
secured a grooved driving pulley e from which passes a band d to and over a guide
pulley e to a grooved pulley on the boss of which is secured a pinion f¹ the band d
returning to the grooved driving pulley e over a guide pulley g.
The pinion driven by the band d passing over the pulley gears into and drives
a wheel h loose on the ordinary back or squaring shaft the wheel h being connected
to and disengaged from the shaft i by the usual clutch which is actuated from the
cam shaft (not shown) by a lever 2 shown in Figs. 1 and 3.
The twist wheel a¹ on the rim shaft a gears into a carrier wheel not shown on the
stud 6' which gears into and drives a spur wheel j' on the stud 2, to the boss of the
wheel is secured a bevel pinion k which gears into a bevel wheel & fast on the front
roller shaft which is thus driven.
By this arrangement I am able to place the front roller shaft on the inner side of
the front end of the rim shaft a and so the roller shaft. and the rim pulley on the
rim shaft are brought much nearer together thereby economising space beyond the
headstock.
Although I prefer the above described arrangement for driving the front roller
shaft it may either be driven by spur wheels and a pair of bevels from the twist
wheel a¹ or in other convenient manner.
The Second Part of my invention refers to the mechanism described in the
Specification to Letters Patent granted to me on the 8th November 1886 No. 14368
for driving the scroll shaft by which the carriage is driven on the inward run.
In carrying out this part of my invention I secure to the loose pulley a² on the rim
shaft a, a grooved pulley / which drives a band m when the main driving belt is on the
loose pulley; the band m passes over a grooved pulley n mounted on a stud n¹ to
which is secured a bevel pinion n which gears into and drives a bevel wheel o' on the
