JONES CB MACHINES
PREFACE
The Singer Model 15, "Improved Family" (Oscillating Shuttle) was produced between 1879 and the early 1890's. Frister & Rossmann started produce their Oscillating Shuttle machine around 1900.
According to my database, Jones CB machines seam to come into production the same year the company ended the production of Spool machines. The early Jones CB have the same decals used for Jones Family CS machines , for Jones Medium CS and Jones Spool machines. This style of machines were possibly manufactured between 1930 and 1941 c..
TYPE 11
from 1930 c.

1955 c.
The Singer 15-91 is the final model in a class beginning in the late 1890's with the 15-30 class, which was replaced in the mid-1930's with the Singer 15-88 treadle operated and 15-89 hand cranked, followed by the 15-90 w/side motor and belt, then the 15-91 w/built-in "potted" motor.
The last Singer 15-91 made by "The Singer Manufacturing Company" was in the mid 1950's.
The Singer 15-91 in the photo on the left was built in 1953, according to the Singer machine serial numbers lookup (for double letter prefixes). It was fully functional, with a rebuilt "potted" motor.
This Singer 15-91 is capable of sewing cloth and Denim fabrics to over 5/16" thick with the standard foot. This includes materials like Sunbrella. Sewing sticky materials, like Marine Vinyl and soft leather, requires an even-feed-walking foot, or a roller foot attachment (low shank). The standard steel presser foot, when sufficiently tensioned down to prevent the material from lifting with the needle, usually drags the top layer of sticky material out of alignment with the other layers. An even-feed or roller foot compensates for this and allows the top layer to move freely, while still maintaining sufficient top pressure as the needle moves up. It also reduces the maximum clearance under the foot by about 1/16 inch.
The Singer 15-91 uses standard household series HAx1, which is available wherever home sewing needles are sold. Note, that on a Singer 15-91, the needle's flat side and eye faces left and it threads from right to left. The maximum needle size available is #125/20, which is good for sewing through thick material. The largest thread size it can properly sew and tension is #92 bonded nylon, but it is best limited to #69 nylon. Too much thread tension will overstress the take-up parts and the motor.
