good conditions. The causes for this are the following:

1. The back spring may be warped, even slightly (1 or 2

spirals).

2. Length of the small chain may not tally with

requirements: it should be sufficiently long to allow a

maximum expansion of the back spring from 45 to 48

mm (1.77 to 1.89 inches) from plate. (See figure 4).

3. The chain must not be twisted.

4. The pulley fixed to the plate must move freely.

Next, see whether the regulating mechanism is in good

order. The rotatory movement of regulator R (Figures 3 and

6) must frictionally drive regulator tube V and thereby impart

a vertical movement to regulating sleeve X (Figure 3).

When the framework has been completely dismantled,

check that pivot holes of the intermediate wheel and the barrel

pivot holes are clean and well polished. These three pivot

holes are the only parts of the clock mechanism which should

be oiled besides the lubrication of the mainspring. The three

pivot holes must be slightly oiled with a fine, not too fluid,

lubricant (Chronax D or E, or Moebius No. 3). Also lightly

lubricate the mainspring.

When the gear-train has been remounted, use Chain Hook,

Tool No. 2 (Figure 5) to replace back spring. A small hook

can be fashioned from a piece of stiff wire.

In the event of faulty adjustment, check one factor very

thoroughly, vis., the suspension wire and its regulating

mechanism.

To unscrew balance, use Key No. 6 (Figure 5) to unlock

suspension wire clamping screw inside the balance tube.

When this screw has been removed, the wire should appear

in the screw arbor lying straight without bend or torsion. It

must be held very tightly in the screw to prevent it from

slipping. Through the medium of the regulating mechanism,

the regulating clamp allows for readjustments by alteration

of the working length of the wire. The clamp must grip the

wire lightly but sufficiently firm to carry the heavy weight of

the balance securely. The two lips of the clamp must lie

perfectly parallel to one another and hold the wire at their

extremities.

The inside of the balance tube, (M - Figure 1) which

passes the suspension wire, must be absolutely clean.

The impulse pin must move perfectly free on its staff.
