| Grant date for this patent also listed as 21 Jan., 1829.
Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. Only the patent drawing is available. This patent is in the database for reference only.
"The circular plate described in the ring groove spinner, is in this improvement made deep, say about an inch, so as to form a tube, and is placed and confined like the plate in the former. There is in this apparatus, a part called the cap, which answers the purpose of a ring, in the ring groove spinner. This cap rests upon a rim which projects inwards about an eighth of an inch, on the lower edge of the tube; this cap is made in the form of a liquor tunnel, with its nose upwards; it encompasses the bobbin, which may be a common weaver's, or shuttle, bobbin, split in the manner and for the purpose described in the ring groove spinner. The lower edge of the cap, which acts on the yarn, is perfectly smooth and polished. When the bobbin is a common spinning, or throstle, bobbin, the cap is of one diameter throughout, forming a straight tube of the length of the bobbin, with a head at the top; which head is pierced through its centre, which steadies it on the spindle, or the tube may be considerably less in length, open at both ends, so as to allow the bobbin to pass up and down through it.
A thin, round, flat piece of metal, larger in diameter than the largest diameter of the cap, with a tube long enough to steady it, is placed horizontally on the top of the bobbin, or spindle, so that it can be removed and replaced with ease. Small, polished notches on the edge of this plate, assist the yarn in revolving round the cap.
The plates and caps may be made of any suitable metal and may be about one-sixteenth of an inch in thickness. Fig. 5th, plate 1, represents the cap spinner:
A, A, A, are pieces of common step-rail, spindle-rail, and vibrating-rail.
B, a spindle of the common kind, excepting that it has no flyer.
C, the whorl, confined to the spindle.
D, a box, being the upper bearing of the spindle, and in which it turns.
E, a common weaver's or shuttle bobbin, crowded on the spindle.
F, the thin, tubular, circular plate.
G, arms belonging to, and extending back from, the plate.
H, an arm, or stud, extending upwards from the vibrating rail.
I, A pin, or pivot, passing through the arms G, and stud H, forming a joint.
K, the conical socket, called the cap.
L, the thin, flat, notched, circular plate, fixed on the spindle.
Th yarn is represented as it comes down from the rollers of a common throstle or spinning frame.
The plate F, is about one-eighth of an inch thick, about an inch deep, and about one and three-eighths of an inch in diameter within. It is connected to the vibrating rail by a joint, as represented in the plate at G, H; the pin İ, forming the pivot.
To find the end of the yarn when broken, the plate is lifted up, and the end of the yarn taken from the bobbin below the plate, and the plate being open in front, the yarn is then passed through it to the cap; or the cap may be lifted for the purpose of mending, or piecing the yarn, in which .case the plate may be bolted to the vibrating rail, and need not be open in front, as represented in the drawing.
The wood cut in the margin, represents the cap when constructed in the manner best suited for spinning on a common throstle bobbin, or a bobbin with two heads.
In this the cap is taken off, for the purpose of mending, or piecing the yarn, as above described."
