. Mechanical appliances, mechanical movements and novelties of construction; a complete work and a continuation, as a second volume, of the author's book entitled "Mechanical movements, powers and devices" ... including an explanatory chapter on the leading conceptions of perpetual motion existing during the past three centuries. he ratchetbar, I, which acts upon the pallets, a, b, in alternation, allowing thespring attached to the paper carriage to move forward one spaceat a time, as the pallets, a, b, escape from the teeth of the ratchetbar I. When a key is depressed to print a character upon the papercarried by the roller, B, the bar, F, will be moved down and the rack bar,I, shifted from the pallet, b, to the pallet a. This is done without anymovement of the carriage ; but when the key is released and the rackbar, I, returns to its position on the pallet, b, it allows the paper carriageto move forward one notch. If a greater space is desired than thenormal action of the machine provides, the space bar, E, is touchedimmediately after printing the character, and if a space is requiredwithout writing, the space bar, E, alone is operated. so MISCELLANEOUS DEVICES. 896.
