IMPROVED HAY-ROPE MACHINE.


Hay-ropes are used for many purposes, their principal use being in the
foundry for core-making; but they also find a large application for
packing ironmongery and furniture. The inventor is James Pollard, of the
Atlas Foundry, Burnley.

The chief part of the mechanism is carried in an open frame, having
journals attached to its two ends, which revolve in bearings. The frame
is driven by the rope pulley. The journal at the left hand is hollow;
the pinion upon it is stationary, being fixed to the bracket of bearing.
The pinion gearing into it is therefore revolved by the revolution of
the frame, and through the medium of bevel wheels actuates a transverse
shaft, parallel to which rollers, and driven by wheels off it, is a
double screw, which traverses a "builder" to and fro across the width of
frame. The builder is merely the eye through which the band passes, and
its office is to lay the band properly on the bobbin. The latter is
turned to coil on the band by a pitch chain from the builder screw, the
motion being given through a friction clutch, to allow for slip as the
bobbin or coil gets larger, for obviously the bobbin as it gets larger
is not required to turn so fast to coil up the band produced as when it
is smaller. If the action is studied, it will be seen that the twist is
put in between the bobbin and the hollow journal, and every revolution
