I. Dobby Card Punching Machines.

These machines, illustrated by [Fig. 1.], (W. P. Uhlinger, builder), are used for stamping cards for the smaller Jacquard machines, technically termed “Dobbies.” They are of very compact build, and operated by belt-power. The whole card is punched at one revolution or stroke. The rack on top of the machine holds the design. The punches for peg-holes and lace-holes are immovable, while the key punches act independently, at the will of the operator. Jacquard cards for these machines are generally composed of the strongest pasteboard, and require a very strongly constructed machine.

II. Piano Card Stamping Machines.

These are operated in two ways, by the belt or foot-power. There are two kinds of each: “French index” and “American index.”
