TRANSPORTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 615,043, dated November 29, 1898. Application filed December 7, 1896. fierial No. 614,781. (No model.)

To aZZ whom it may concern: Be it known that I, FRANK SAMUEL Pnrr, a subject of the Queen of Great Britain and Ireland, residing at 3 Blenheim Square, Dover, 5 in the county of Kent, England, have invented certain new and useful Improvements in Transporting Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will I0 enable others skilled in the art to which it appertains to make and use the same.

This invention for improvements in transporting apparatus has for its object to facilitate the transportation or loading or unloading of cargo; and it consists of a beam or girder adapted to be fixed or supported in the required position to transfer the cargo, a carriage adapted to travel along and be guided by the beam two sprocket-wheels, with a ratchet-wheel bolted securely onto the side of each sprocket-wheel, mounted on the carriage, two chains passing over the sprocketwheels and along the beam in reverse directions, ratchet mechanism adapted when in 2 5 gear to prevent the sprocket-wheels turning in a direction to lower the chains, and a means for moving the ratchet out of gear when desired.

When the apparatus is used to transfer a load from the outer end of the beam to the inner, the chain passing to the outer end is hauled on until the block comes in contact with the carriage. The carriage is then pulled by this chain to the outer end of the beam 3 5 and is secured from inward movement by belaying or fastening this chain. The other or hauling chain is then hooked onto the load and hove up, and when the load is at the desired height the belaying-chain is unfastened, the

continued hauling on the chain then traversing the carriage and its load along the beam, the ratchet mechanism preventing the load from lowering during this traverse. \Vhen the load arrives at the required place, the carriage is prevented from further inward movement by coming against a stop or by fastening the belaying-chain, the ratchet is drawn out of gear by a rope or automatically by a projection on the beam, and the hauling-chain is slackened to lower the load.

When the apparatus is used to transfer a load from the inner end to the outer end, the functions of the chains are reversed, the chain passing to the inner end now becoming the belaying-chain and the chain passing to the outer end the hauling-chain.

By this apparatus the load can thus be transferred inward or outward at pleasure without altering the chains.

In the accompanying sheets of drawings, Figure 1 is an elevation of an apparatus with one cheek of the carriage and the ratchet and its lever for working the inside ratchet-wheel removed arranged for outward transportation and constructed according to this invention, showing the position of the parts as the load is being raised and in dotted lines the position when being transported; and Fig.2 is a similar view arranged for inward transportation showing the two ratchets and their levers 7o thrown out of gear. Fig. 3 is a plan of Fig.

2. Fig. 4 is a sectional elevation of the transporting-carriage with one check of the carriage and the ratchet and its lever for working the inside ratchet-wheel removed, the dotted ratchet and the lever showing the position when in gear and the full-lines ratchet and its lever showing the position when tripped ready for hoisting a load; and Fig. 5 a sectional end view of the same. Fig. 6 is a similar view to Fig. 4, showing a slight modification. Fig. 7 is a view showing a modification of the apparatus arranged for transporting cargo in the hold of a vessel.

The beam ct is suspended by span b from the ships mast by means of a tackle or other suitable support and is stayed by means of ropes at its ends to other fixtures. As shown, the beam is double, so that loading or unloading operations can be conducted at either or at both ends and is .L-shaped incross-section.

The carriage 0 works underneath the beam to and is provided with side cheeks, carrying rollers 61 running on the top surface of the head or flanges of the beam or girder, so that 5 the carriage is free to run from end to end of the beam.

Two sprocket-wheels e e are mounted on the carriage 0 below the beam, and the inner sprocket-wheel e is provided with a ratchet wheel f and ratchet g, preventing when in gear its rotation in a forward direction, and the outer sheave e is provided with a ratchetwheel f and ratchet g, preventing when in gear its rotation in the backward direction.

In order to throw the ratchets g g out of gear with their ratchet-wheels f f automatically at the desired parts of the beam, the beam to is provided on its under side at the said parts with projections 71/ j, and when the carriage is traversed on and over them the projections come in contact with either of the tails t' t" on the ratchets or the separate levers ZZ, acting on the ratchets, and throws the ratchets out of gear. The ratchet-wheel g is shown in Fig. 1 in gear with its ratchet-wheel f in dotted lines and forced out of gear by the projection 7i, acting on the lever Z, in full lines, and Fig. 2 shows the projection j acting on the ratchets and levers throwing the ratchets g 9 out of gear with their ratchetwheels. Thus at both ends of the traverse both ratchets are thrown out of gear with their ratchet wheels, and the sprocketwheels are free to revolve in either direction. Springs 0' s r s tend to put the ratchets in gear with their ratchet-wheels.

Chains m m are passed over the sprocketwheels 6 e, thence over guide-pulleys n 71/ on the beam, so that the chains are practically parallel with the beam, and thence over suitable guide-pulleys 0 to any desired spot for manipulation. The chains m m are provided with blocks 2) p, that come in contact with the carriage-frame and prevent the chains from being hauled in any farther.

The operation is as follows: The carriagec is hauled inward by means of the chain m to the position shown in Fig. 1, the block 12 coming in contact with the carriage c and fixing the chain m with reference to the carriage c and the chain m being paid out as required. In this position the ratchet gis thrown out of gear with its ratchet-wheel f by the projection 71, acting on the lever Z, that forces the ratchet out of gear, and the chain on is lowered to receive the load. The load is then hauled up by the chain m, and when the load is at the desired height the chain m is released, so that the pull on the chain on traverses the load outward along the beam. Immediately the lever Z leaves the projection h the ratchet 9 falls into gear with its ratchetwheel and prevents the load from lowering, but it can be raised still farther, if desired, by holding on to the chain m. At the outer end of the beam the carriage 0 comes against the stops t, and the projection j, acting on the tail t'of the ratchet g, raises the ratchet out of gear with the ratchet-wheel, so that the load can be lowered. By this arrangement it is not necessary to pay out the belaying-chain at the same speed as the hauling-chain, the belaying-chain being used only to fix the carriage at the desired spot.

It will readily be understood that when desired to traverse the load inward the chain m becomes the hauling-chain,while the chain m is the belaying-chain, as shown in Fig. 1, the ratchet g then acting on its ratchet-wheel f, as previously described for the ratchet g and ratchet-wheel f.

In the modification shown in Fig. 6 the ratchet-wheel and ratchet are replaced by the drum or brake surfaces 12 c and straps or bands 10 w and levers w 00', and in this arran gement the brake is applied by the projection 1 when traversing outward to the drum t and when traversing inward to the drum 1), the projection g extending the whole distance of the traverse. At places where it is necessary to lower, the projection y is removed to enable the brake-levers to release themselves.

Fig. 7 shows thebeam a supported from the deck-beams 1 by means of the hangers 2. The arrangement is suitable for transferring cargo from any part of the ships hold to under the hatchway 8, and in this case the levers Z Z are dispensed with.

It will readily be understood that the apparatus may be employed in warehouses or on other places where it is desired to handle goods or cargo for loading or unloading purposes or for storage.

Instead of operating the ratchets automatically they may be attached to a rope, by which they can be pulled out of gear at any desired place, so that the load can be deposited at any part of the length of the beam, and the ratchets may be dispensed with altogether and kept out of gear by a pin inserted in the holes 4 across the carriage, as shown in Fig. 4c. This, however, is only done when landing cargo on deck and when traverse is not necessary.

'What I claim, and desire to secure by Letters Patent, is

A load-transportin g or loading and unload ing apparatus, consisting of a beam, a carriage running on the beam, of two sprocketwheels mounted in the carriage and of two chains passing from the sprocket-wheels along the beam in opposite directions, ratchet or brake arrangements to prevent the rotation of the sprocket-wheels in adirection to lower the load and means of throwing the ratchets or brakes out of gear automatically or otherwise so that loads can be transferred in either direction without unreaving the chains.

In testimony whereof I have affixed my signature in presence of two witnesses.

FRANK SAM UEL PETT.
