Before electricity, dogs played a part in the history of sewing machines. In the 1870s-1880s, inventors came up with ways to use dogs to power the machines.
|The treadmill was invented by M. Richard of Paris. It is said he used this contraption briefly in the 1880s to power a large number of sewing machines in his factory to make military uniforms.|
I am not sure if the following designs were ever used.
|The carousel was patented in England around 1874. A hitching position for a second dog is provided.|
|The wheel was patented by Heinrich Feldt of Hamburg in 1888.|
