Complete Left, 2nd May, 1887.
Complete Accepted, 3rd June, 1887.
We, JOHN CHARLES COTTAM, of 39 Lombard Street, in the City of London,
Financier, and ALBERT DOUGLAS MOLL, of 58 Coleman Street, in the City of London,
Merchant, do hereby declare the nature of the said invention to be as follows:-
Our Invention relates to Improvements in the Sewing Machine as patented to Sally
Adolf Rosenthal under No. 15513 and date the 17th December 1885, and consists in
a Modification of the Mechanism by which motion is communicated to the operating
parts of the said Sewing Machine.
We cause the axis of the oscillating Shuttle cradle to be carried through the frame
in a suitable bearing, and to be provided outside the frame with a handle by which
the said Shuttle Cradle can be rocked or oscillated.
Suitable stops are provided to check the oscillatory movement of the said Cradle axis
within the required limits.
The Vertically reciprocating needle bar may receive its motion either by a connecting
rod attached to a crank pin on the said hand rocking bar; or by a pin projecting
from the said needle bar engaging in a slotted cam plate on the said hand rocking
bar; or by a cam affixed to the said hand rocking bar operating the needle bar
against a suitable spring reaction.

page_text: We, JOHN CHARLES COTTAM, of 39 Lombard Street, in the City of London,
Financier, and ALBERT DOUGLAS MOLL, of 58 Coleman Street, in the City of London,
Merchant, do hereby declare the nature of this invention and in what manner the.
same is to be performed to be particularly described and ascertained in and by the
following statement:―
Our invention relates to improvements in the sewing machine as patented to
Sally Adolf Rosenthal under No. 15513 and dated 17th of December 1885, and
consists in a modification of the mechanism by which motion is communicated to the
operating parts of the said sewing machine.

In order that our invention may be the better understood, we now proceed to 1
describe the same, reference being had to the drawings hereto annexed and to the
letters and figures marked thereon.
Figure 1 is a side elevation of the said modification.
Figure 2 is a front elevation of the same.
Figures 3 and 4 show side and front elevations of the same machine with slight
modification in the construction of the frame and disposition of the spring where
used.
The axis A of the oscillating shuttle carrier B is carried through the frame C in a
suitable bearing, and is provided outside the frame with a hand lever D by which the
said shuttle carrier B may be rocked or oscillated. The vertically reciprocating needle
bar E may receive its motion either as shown by the connecting rod F, attached to
the said hand lever D, by which the necessary stroke of the needle is effected, and
also the necessary feed movement as in the aforesaid original patent No. 15,513
of 1885.
Or the said needle bar may be operated by a cam plate affixed to the said hand
lever bar D, operating the needle bar against a suitable spring reaction.
Or, a pin projecting from the said needle bar E may engage in a slot in a cam plate
affixed to the said rocking hand lever D.
The shuttle carrier B may be affixed to the same axis to which the hand lever D is
attached, and may thus receive its movement direct from the hand lever D; or, the
said shuttle carrier may be provided with a curved slot, as in the original patent
No. 15513 of 1885, into which a pin upon the needle bar may engage, and the
necessary oscillatory movement of the said shuttle carrier will, in this case, be
produced from the reciprocating movement of the needle bar E, as in the aforesaid
original patent No. 15513 of 1885.
Suitable stops may be provided to check the oscillatory movement of the said hand
lever within the required limits. These may be either stops fixed upon the frame of
the machine, or the necessary checks may be provided by the ends of the needle bar
striking upon the extremities of the frame slot in which it travels. We may construct

page_text: the needle bar in a cylindrical form fitted in a bored guide through the centre of the
frame, as shown in figures 3 and 4. In this case, where a spring is used, the spring G
may be placed in a bored cavity within the said cylindrical needle bar, where it is
thus protected and hidden from sight.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is :-
1st. The combination with a pocket lock stitch sewing machine, as patented under
No. 15513 of 1885, with a hand lever operating the needle bar from a connecting rod
or cam by an oscillating movement about the axis of the shuttle carrier, substantially
as described.
2nd. In such a pocket lock stitch sewing machine, the operation of the shuttlo
carrier direct by the oscillatory movement of a hand lever applied to its axis, the
reciprocating movement of the needle bar being produced therefrom by a connecting
rod, cam or cam slot, substantially as described.
