suitable
To effect this, we apply a small hand wheel with a horizontal axis,
point in the frame of the machine, and may operate the vertically reciprocating needle
bar and the oscillating shuttle cradle by connecting rods from a crank pin, or by an
Eccentric, cam, or other similar device on the said rotating hand wheel axle.
Or we may apply the said hand wheel with horizontal axle below the working table
at either side, and in such position the reciprocating movement of the needle bar and
oscillation of the shuttle cradle may be obtained by the movement of a crank pin on
the said hand wheel, in a horizontal and vertical or oblique slots therein respectively.

Improvements in Pocket Sewing Machines.
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 our 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 upon the sewing machine patented to Sally
Adolf Rosenthal under No. 15513 and date December 17th 1885, and consists in
combining with the parts therein described a rotary driving movement for their
operation.
In order that our invention may be the better understood, we now proceed to
describe the same, reference being had to the drawings hereunto annexed and to the
letters and figures marked thereon.
Figure 1 is an end elevation of a rotary movement operating the needle bar and
shuttle carrier direct therefrom.
Figure 2 is a front elevation of same.
Figure 3 is a side elevation of an equivalent eccentric rotary driving apparatus
operating the needle bar, which in turn works the shuttle carrier.
Figure 4 is a back elevation of a geared rotary driving apparatus.
In figures 1 and 2, we apply a small hand wheel A provided with a handle B,
rotating on a horizontal axis Cat the lower part of the frame. The handle B of this
rotating wheel is utilized as a crank pin, to produce the reciprocating movement of
the needle bar D, by means of the connecting rod E. Or, a double bent wire crank
may be used for the purpose. On the axis C of the hand wheel A is fitted, at the
other extremity, a crank pin a, which, working in the slot of the shuttle carrier F,
preduces the necessary reciprocation of the said shuttle carrier by the rotation of the
hand wheel and axis. The other parts of the sewing machine may be constructed
according to the patent of the said Sally Adolf Rosenthal or of other equivalent
description.
In figure 3, we apply an eccentric tumbler G rotated on the eccentric pivot H, by
means of a handle g, and thereby giving reciprocating movement to the strap and
connecting rod h, which effects the up and down stroke of the needle bar D. The
driving pin a, on the extremity of the needle bar working in a suitable curved slot in
the shuttle carrier F, may produce the necessary reciprocation to the shuttle in the
same manner as in the aforesaid patent. No. 15513 of 1885.
In figure 4, K is the first motion shaft rotated by the handle k, which, carrying the
cog wheel L, transmits movement with a multiplied velocity to the small pinion M.
This latter pinion and shaft provided with a crank arm m, transmits reciprocating

page_text: movement to the needle bar D, by means of the connecting rod E. The movement of
the shuttle carrier is communicated from the reciprocations of the said needle bar by
the ordinary driving pin a.
It is obvious that there may be other simpler and equivalent methods of communi-
cating the necessary movement to the needle bar and shuttle plate from a preliminary
rotary motion without departing from the essence of our invention.
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
The combination in the pocket sewing machine as patented to Sally Adolf Rosenthal
under No. 15513 and date December 17th 1885 of a rotary driving movement
whereby the necessary movement of the needle bar and shuttle carrier may be effected,
substantially as described.
