From "The English Mechanic and World of Science" number 702, September 6th 1878
The English Mechanic and other scientific papers have of late repeatedly pointed out the injurious effects the working of sewing machines has on women. The body of necessity is bent forward, the lungs are subjected to undue pressure, and consequently the respiration is hindered and retarded, and the blood is pressed to the head, not by this position alone, but also by the motion of the legs in driving the machine. A convenient motor for the sewing machine has been for some time a thing wished for by the friends of those humble hardworking sempstresses who strive to earn their scanty living by efforts of their own.
We have seen the water motors exhibited by the Western Company in Queen Victoria-street, and found them very good. But water motors can not be fixed anywhere, and removed again with ease.
M. Gunzberger, route d'Epinay, St. Denis, France, exhibits a very efficient spring motor, which takes up little space, can be placed anywhere, and can be removed without difficulty, and requires no fixtures (as water motors will do). See illustration, Fig. 1.
The motor is wound up like any clockwork; to wind it fully 2 1/2 minutes are required - the machine will then go on for 20 minutes. The motor can be rewound while still at work, so that no awkward delay need occur; and a break-block and lever, to be governed with one foot, enable the worker to obtain any degree of speed, and to stop the machine in a second.
The price of the motor alone is £14, or 350 francs; motor and sewing machine, complete, £55, or 550 francs. The apparatus is fitted up with a governor to insure uniformity of speed, and the exhibitor affirms that the regularity of motion thus obtained allows better work to be produced, and saves the sewing machine from being used out in a short time.
We trust some enterprising firm of sewing-machine sellers will introduce the motor to public notice in London.
