HENRY GARDNER, of the Firm of Robertson, Brooman, and Company, of 166,
Fleet Street, in the City of London, Patent Agents. " IMPROVED ' TAKE-UP
MECHANISM FOR SEWING MACHINES." A communication from abroad by the Firm
R. M. Wanzer and Company, of Hamilton, Ontario, Canada.
This Invention relates to improved take-up mechanism for sewing machines,
and will be clearly understood by the following description and the annexed
Drawings:-
Figure 1 is a top view, Figure 2 is a face view, and Figure 3, a side view of
the take-up mechanism.
a is the needle bar; b, a section of frame of machine; c is a connection; d is a
tumbler or cam; e is a bracket; fis the take-up bar or lever; and g is the point
of the cam.
The dotted lines on Figure 2 shew the whole throw of the lever bar. The take-
up g moves in a circle, and has to travel more than one-half of the whole circle. To
do that the point g is required to pass the connection over centre.
The main feature of this Invention is, the point g on tumbler or cam working in
connection with the point h on the needle bar, for the purpose of revolving the
tumbler to a position for the connection to finish the motion.

HENRY GARDNER, of the Firm of Robertson, Brooman, and Company, of 166,
Fleet Street, in the City of London, Patent Agents. " IMPROVED TAKE-UP
MECHANISM FOR SEWING MACHINES." (A communication from abroad by the Firm
R. M. Wanzer and Company, of Hamilton, Ontario, Canada.)
This Invention relates to improved "take-up" mechanism for sewing machines,
and will be clearly understood by the following description and the annexed
Drawings:-
-
Figure 1 is a top view, Figure 2 is a face view, and Figure 3, a side view of the
take-up mechanism.
a is the needle bar; b, a section of frame of machine; c is a connection; d is a
tumbler or cam; e is a bracket; fis the take-up bar or lever; and g is the point of
the cam.
The action of the mechanism is as follows:-The dotted lines on Figure 2 shew
the whole throw of the needle bar; the take-up fmoves in a circle, and has to
travel more than one-half of a whole circle. In order to do that the point g is
required to pass the connection cover the centre, as will be seen by referring to the
Drawing.
The main feature of this Invention, and that which I consider novel, and to which I
lay claim, is, the point g on the tumbler or cam d, working in connection with the
point h on the needle bar a, for the purpose of revolving the tumbler & to a position
for the connecting piece c to finish the "take-up" motion.
In witness whereof, I, the said Henry Gardner, have hereunto set my hand
and seal, this Sixteenth day of April, One thousand eight hundred and
seventy-eight.
H. GARDNER. (L.S.)
