SPECIFICATION forming part. of Iietters Patent No. 30,6,711, dated October 21, 1884.

Application filed August 2, 1854. (No model.) Patented in England May 4, 1888, No. 2,254.

To all whom it may concern:

Be it known that I, CHARLES JAMES Ar- PLEBY, of London, in the county of Middlesex and Kingdom of Great Britain, have invented certain new and useful Improvements in Cranes, and I do hereby declare the following' to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to inake and use the same. n

My invention relates to an improvement in cranes, and especially cranes actuated by steam-power and adapted for use in discharging coal or other cargo from vessels, the obj ect of the same being to construct and arrange the several parts of a crane in a novel manner, so that they are verystrong and accessible, easily put together and worked, and at t-he same time durable and effective for the purposes to which they are to be applied; and with these ends in view my invention consists in certain features of construction and combinations of parts, as will be hereinafterdescribed, and pointed out in the claims.

In 'the accompanying drawings, Figure l is an elevation, Fig. 2a plan, and Fig. 3 a front v1ew,showing my invention applied to a steamcrane, which is supposed to be iiXed upon the edge of a wharf' or in other convenient position, and used for the purpose of lifting and movmg coal or other goods to or from vessels moored against the wharf, the boiler actuating the steamcngines being situated in any convenient position in the neighborhood.

a is a bed or foundation of wrought-iron plates riveted to angle-irons and bolted to stone, wood, or other suitable support, such as a east-iron bed-plate with a ilat ring on its upper surf'acc at or near the edge of the wharf. Upon the top of this bed a, I bolt or nx a circular path or rail, b, preferably of steel, upon which the wheels c c c, supporting the crane itself, travel when the latter is slewed or made to revolve round its central axis. Inside the D bed a, arranged as described, l fix a frame,

preferably of cast-iron, and consisting'of a center, d, with sufficiently strong radial arms or ribs, and through the center d passes the hollow vertical post or pivot c of iron or steel, round which the carriage of the crane and the craneitself revolve. The carriage of the crane consists of a horizontal frame-work, f, preferably of iron beams bolted together, arranged above the bed a, and provided with bearings at g, g, and y?, in which are iitted the radial axles of the wheels c c c2, which are supported by and run upon the circular steel path b. Two of t-hese wheels, c and c', are arranged at a sufficient distance apart at the front of the crane, as shown in Fig. 2, and the third, c2, at 6o the back, and the part of the frame which carries the two front wheels, c c', is preferably made separate from the remainder, to which it is fitted and bolted, as shown in Fig. 2, so that it can very easily be removed together with the wheels cc', if the latter at any time require repair or adjustment.

Upon the outer parallel sides of the frame f, arranged as described, or 011 the revolving bed-plate are fixed two horizontal s team-cyl- 7o inders, h 71.', driving in the usual way a transverse horizontal shaft, t', upon which is fitted a toothed pinion, 7.', which gears with and drives acci-responding toothed wheel, Z,`Xed upon a parallel transverseshaft, m, arranged 7 5 above and revolving in brackets or bearings n n', fixed or formed upon the frame-work or platform of the crane. This shaft m also carries a winding-drum, o, round which is wound a wire rope or chain, b v which the weight is So lifted or lowered, as desired. This method of arrangement allows the use'of a winding drum and gear of large diameter. Thetoothed pinion his provided with a friction-clutch box,

p, or any other suitable kind of clutch, by which it can be connected to the engine-shaft t' or disconnected, as desired, by means of a handle arranged in a convenient position, as shown at r. Reversinggear operated by a handle, s, near the handle r, is provided to the 9o engines, and the steam-pipes t and exhaustpipes u from the engines are carried down through the hollow central post, e, thesteampipe t passing through the eXha-ust-pipeu and being carried to and connected to the boiler, and the exhaust-pipe a being conducted to any convenient position for the discharge of the exhauststeam, suitable stuffing-boxes being provided at r e, so that the crane can be slewed or turned round upon its central pivot roo m and provided with a handle or foot-lever at y, by which it can be operated, the lever being preferably provided with a ratchet and pawl, by ineans of which it can be held in any desired position. Each of the axles of the front bearing-wheels, c o', has fixed upon it a beveled toothed wheel, 1 2, between which and gearing with them is arranged a third beveled toothed pinion, 3, fixed upon a horizontal shaft, L1, running in bearings at right angles to the engineshaft i, and having fixed upon its outer end a spur-wheel, 5, gearing with and driven by a correspondingpinion, ti, upon the shaft 7, which revolves in bearings 9 upon the upper side of the frame. The other or inner end of the shaft 7 has fixed upon it a beveled toothed wheel, 10, gearing into two corresponding beveled toothed pinions, 11 12, which revolve freely upon the engine-shaft fi, but are fitted with friction-coupling boxes, so that either of them, as desired, can be connected with and driven by the engine-shaft i, Va movable coupling, 13, upon the latter being connected to a handle, 111-, arranged in the neighborhood of the other handles already described. In this way the two front bearing-wheels, c c, of the crane can be iliade to turn in either direction, and the crane is thus slowed round its central post or pivot, e, either to the right or left, as desired.

In order to effect the raising or lowering of thejib of the crane, I use the following novel method of construction and arrangement: I make the lower end, A, of the jib turn in the usual way upon horizontal pivots I3 at the front of the frame-work of the crane, and upon the saine pivots I lit the lower ends of sufficiently strong struts (l, arranged at or about at right angles to thejib, their upper ends being attached to the lower ends of tensionrods l), the upper outer ends of which are fixed to the outer end of the jib E. The struts C are provided with transverse stays, ,and at their upper end is fitted a pulley, F, round which passes a chain or rope, G, by means of which the entire jib can be raised or lowered, as desired. One4 end of the chain G is fixed to a lug or attachment, II, at the back end of the frame-wirk of the crane, and its other end, after passing round the pulley F, is brought back and attached to the hoisting pulley or drum I, fixed upon a transverse shaft, K, turningin bearings below'theback en d oftheframework. The trz'insverse shaft K has also fixed upon it a tangent toothed wheel, Il, gearing with and driven byan endless screw, M, fixed upon the longitudinal shaft N, which revolves in bearings O O, carried upon the framework of the crane, the frontend of the shaft hav ing fixed upon it a second tangent toothed wheel, I), gearing with and driven by an cndless screw, Il, fixed upon the transverse shaft S, also revolving in bearings carried by the framework of the crane, and having fixed upon it at a convenient part of its length a toothed wheel, 'l, gearing into a corresponding toothed wheel, U, fitted upon the engineshaft, and provided with a clutch-box, V, as shown in Itig. "2, by which it can be connected to or disengaged from the latter, the clutchbox V being operated by means of a handle, X, situated in the neighborhood of the other handles already described. By the means described and shown, therefore, the drum or pulley I vcan be connected with or diseouneeted from the engine shaft, and the jib raised or lowered, as desired. A hoisting drum or pulley and chain are fixed at each end of the transverse shaft li, as'shown in Fig. 2.

ln Fig. Lt is shown an elevation of amoditied form of arrangementin which the boiler 15 is carried in the usual way upon the back of the platform 1G of the crane, the steam-pipe t and exhaust-pipe a being connected directly to the boiler. In this method ot' construction the platform a., upon which the crane turns, may be mounted, as shown, upon a carriage, 17, the wheels of which-preferably sixrun upon a railway, 1S, and these wheels may be coupled together, as shown, by e'ndless chains 19 passing round suitable-wheels upon their axles, one of the latter being actuated by an arrangement (not shown in the drawings) ol' beveled toothed wheels driven by a vertical shaft passing through the hollow center c, round which the crane turns, the upper end of the shaft being driven by toothed gear connected with the driving'shaft of the engine, a suitable clutclrbox being arranged by which it can be thrown in orout of gear, so as to propel the entiie apparatus in either direction along the railway 1S as and when desired, \Vhere it is not required that the jib should be capable of being raised or lowered, as above described, the chains or ropes and the gear for actuating them for such purpose are omitted, and the upper' ends ofthe struts (l are eonneeted directly tothe back end of the platm form by tensioirrods.

In Fig. 5 shown a novel method ofarrangement which I sometimes adapt to the crane apparatus for thepurpose of weighing the coals or other articles raised at the same time that they are suspended tothe end of the jib, such apparatus consisting of a horizontal lever, 20, one

end of which is pivoted in the end of jib at 2l., while its other end carries a pin upon which the jib' sheave or pulley 22 revtgilvcs, the ends of the pin moving freely within suliicientlimits lin vertical holes or slots in the jib ends. \Vhen thc weight 23 is suspended from the pulley 22, it depresses a vertical rod, 2l, the lower end of which operates upon the short end 25 of a bell-cranlrlever, to the longer arm of which, 2G, a tension-rod, 2T, is jointed, which passes down the jib, and is connected at its lower end to ashort arm, 28,'of a second bell-crank lever, the longer arm of which, 2t), is provided with a springbalance, 30, or equivalent; device, by which the weight is indicated. rllhe arm 2t) is also provided with an adjustable weight, 31, by which the permanent weight of the levers and skip is balanced.

Having fully described my invention, what IOO IIO
