MODELS OF A PRIMITIVE LOOM AND A JACQUARD LOOM. 



The lower figure shows the structure of the primitive 

 weaving apparatus, which employs the same principles that 

 are utilized in the modern power loom. The upper figure 

 shows the remarkable apparatus invented in 1728 by the 

 Frenchman, Jacquard, with the aid of which complicated 

 patterns are woven. A chain of punctured cards determines 

 the pattern. The loom to which the Jacquard machine is 

 attached in the above model is weaving a narrow silk ribbon.
