14. Lifting the Presser Bar
Both the vibrating presser and the presser foot are mounted on the presser bar.
The presser bar lifting mechanism is enclosed In the machine arm. To mount the knee lever,
push it over the lower end of vertical shaft r under the tabletop. The lever is held in place by
angular bracket s which snaps Into place after transverse driving pin u has entered cutouts t
in
right-angled coupling sleeve q (Fig, 18).
When the coupling sleeve Is pushed onto the end of the shaft, resilient bracket s must be
compressed to open it slightly.
Motion is transmitted from the vertical shaft to the presser bar by means of a crank, a connection
and a bellcrank lever which raises the presser bar. A small hand lever at the back of the machine
(Fig. 20) serves to lock the vibrating presser and the presser foot in their highest position.
This lever is flicked to the left to retain the presser bar after it has been raised by knee action.
To facilitate the tilting back of the sewing head without removing the knee lever completely,
the knee lever rock shaft is no longer screwed to the angular sleeve, but rather held in place
by a spring-loaded pin v (Fig. 18) so that the knee lever can be pulled forward off its shaft
with a slight jerk.
A new feature of the knee lever is its hinged foam-plastic-padded knee plate which is con
toured to hug the operator's knee.
