Short arm designs like Singer can keep the same shuttle for full size and 3/4 size machines because they can keep the arc the same and just lengthen the driving bar.

Hengstenberg/Anker machine The shuttlesīecause the shuttle must mirror the shape of the arc it is following, the difference in arc curvature makes for different slant of the tip of the shuttle. The Wittler variant is similar but the swinging arm is rotated by 90 degrees. The swinging arm is very short, the arc is steep and the rotation centre is on the left. The Singer and many German machines also have a long arm running along the bed, but it does not swing. This example is by Mundlos who followed the New Home design with their vibrating shuttle machines. The New Home design has a medium-sized arm with a rotation centre pretty much in the middle of the bed. The White and Jones machines have a long arm that swings in a shallow arc, and the rotation centre is quite far to the right. This German design is a variant of Singer’s VS with the shuttle swinging parallel to the arm of the machine, and so its silver band is shorter and runs along the bed of the machine rather than across it.įlip back the machine and have a look at the mechanism inside the base – this is where they differ. There is an exception to this rule: the Hengstenberg/Anker machine with the Wittler mechanism. On the outside, the three designs look very similar: they all have a wide silver band on the bed of the machine perpendicular to the arm. Their harp space (the space under the arm) is similar to that in modern multi-stitch machines with a much larger bed length of 16″ or more, which is sufficient for most domestic use.

Jones called their full size machines Medium CS, 3/4 ones Family CS, CS-E (with an electrical motor), Popular (with a Saxonia-style hand-crank), D53 (with a square boxy body).įull size vibrating shuttle machines of either design are fairly rare. Singer called their full size machines VS2, 3/4 ones VS3. But it’s best to always check to be sure, because the machines made in the USA had very different dimensions, for example.

In Europe, those two sizes were quite well standardised for all three VS designs, so machines of different makes would usually fit into the same cases and treadles. Singer vibrating shuttle machines come in two sizes: full size with the bed length of 14″, and 3/4 size with a 12″ bed (measurements are approximate). In Germany, various makers mostly followed the Singer design, but there were a few notable exceptions. In England, Jones used the White patent and called their White-based machines “CS”, or cylinder shuttle, no doubt in order to differentiate from Singer’s VS. They are all called “VS” which is very confusing. There are three major types: one introduced by Singer, another by New Home and the third one by White. Vibrating shuttle mechanism is the one with the bullet-shaped shuttle moving in an arc.
