Denison's carriage-axle. The bent or crank axle is much used in city drays, its purpose being to lower the bed without reducing the size of the wheels. Bringing the floor of the vehicle nearer to the ground obviates lifting the load to any great extent. The bent axle, to enable the bed of the cart or wagon to come near to the ground, while retaining a large wheel, is a common device in England in city and rural vehicles. One form of driving wheel-axles for locomotives is also bent. Baddeley, a contributor to the early volumes of the Mechanic's Magazine, London, advocated their use, and may have been the inventor. Paterson (England) proposed that carriages should have axles of unequal length, so as to avoid tracking, and thus prevent the formation of ruts. A turning-axle is the fore-axle of a carriage, which turns on the fifth wheel. A leading-axle is an axle of a locomotive, in front of the driving axle or axles. The term is applied especially to the English engines,

olution, and gradually to decrease during the other half. The stroke of the crank may also be varied by shifting the crank-pin in the slot h. A two-throw or three-throw crank-shaft is one having so many cranks set at different angles on the shaft. Crank—ax′le. 1. An axle bent down between the wheels, in order to lower the bed of the wagon and make loading more easy. It has been introduced in England for country and city wagons, and also in the United States. It is credited to Baddeley, an early contributor to the London Mechanic's magazine. 2. (Steam-engine.) The driving-axle to which are connected the piston-rods of a locomotive engine. This is the usual English form; in America we connect to wrists on the drive-wheels. Crank—brace. The usual form of brace, which has a bent shank by which it is rotated. Cranked tool. （Iron-turning.) A tool which is made to embrace the rest a, by which it is prevented from slipping away from the work. A pin is inser

in operation. Both pairs of toggle-arms are operated by a single rope in this latter operation. The lids of the box are balanced by weights to assist in their opening. The passages in the heads for introduction of the hoops are recessed beneath to permit the passage of the arm of the operator, and the box bottom is grooved to guide the hoops from side to side beneath the bale. Port′a-ble pump. One for use in an emergency, or for watering gardens, or emptying cisterns or casks. Baddeley's (A, Fig. 3894) is a combined suction and force pump, designed for irrigating and manuring purposes. It may also be used as a fire-engine. It is mounted on a carriage, and is operated by means of a brake a. An air-chamber b enables a continuous stream to be thrown. Fully and Reece's pump (B) is designed for transferring liquids from casks, etc. For this purpose, it is provided with a conical sleeve a entering the bung-hole and secured by a clamp-screw. It is operated by a crank which

st have turned with difficulty, as the fore-carriage was not swiveled. The illustration is from the Luttrell Psalter, a manuscript of the fourteenth century. Baddeley's wagon. A vehicle on four wheels of equal diameter is of lighter draft than one in which the fore wheels are smaller than the hindwheels, unless the load is distributed on the wheels in proportion to their diameter. In Baddeley's wagon, constructed in reference to this point, the hind wheels are unusually large and bear four fifths of the weight when the body is fully loaded. The axle is bent and the body is supported thereon by three springs, two being used under the fore part. Baddeley contributed a number of papers to the early volumes of the London Mechanics' magazine upon this subject, and is one of those to whom we are indebted for much that is sensible in modern vehicles. A mongrel contrivance, partaking of the features of cart and wagon, has been suggested. The forward end of a two-wheeled ca

plendid working-man in his corduroys stood like a statue, in an attitude of fixed attention. Lowly fathers and mothers carrying small children. One lady, seated high at the base of a column, put her feet on the seat of my stool behind me. Saw the gorgeous ring on the finger of the statue of St. Peter. January 19. Have composed a letter to Professor Lanciani, asking for a talk on the afternoon of February 9, proposing Houses and Housekeeping in Ancient Rome, and The Sibyls of Italy. Mr. Baddeley came in, and we had an interesting talk, mostly about the ancient Caesars, Mrs. Hollins asking, Why did the Romans put up with the bad Caesars? He thought the increase of wealth under Augustus was the beginning of a great deterioration of the people and the officials. January 21. Went in the afternoon to call upon Baroness Giacchetti. Had a pleasant talk with her husband, an enlightened man. He recognizes the present status of Rome as greatly superior to the ancient order of things —
