Patented Feb. 25, 1930 PATENT OFFICE Amman nmmsrnm, or HAMBURG, GERMANY APPARATUS FOR RAISING SHIPS CARGOES Application filed J'uly 25, 1927, Serial No.

In the transference of ships cargoes use has hitherto been made of ordinary ships tackle or crane tackle, which necessitates the packages to be handled being actually grabbed or laid hold of by the tackle and consequently damaged, especially as the goods cannot be prevented from swinging when hanging from the crane.

It is the object 'of the present invention to avoid the possibility of damage to the packages of cargo to be handled. For this purpose a speclal loading platform for raising the cargo is provided on the ship; more particularly a loading platform such as shown 'at a (see Figure 1) guided vertically, against the outer shell of the ship. With reference to the accompanying draw.- 1n s':

.ig. 1 represents a vertical section of a ship and in combination therewith a side elevation of the improved device for raising the cargo;

Fig, 2 shows a side view of the ship and in combinationtherewith a front elevation The said plat cm a is attached to a frame b which is aperturedand'is provided with guide rollers and which may, if desired, be pivoted at a so as to be adapted to fold back on to the-upper deck.

' The latform is so connected to the guide frame y the supporting struts d that it can be held in an approximately horizontal position relatively to the supporting frame but, .in any case, is inclined s ightly towards the side of the ship rather than in the opposite direction. The rollers of the guiding and supporting frame run in guide bars e, which are attached vertically to the ships side for instance, by means of flat socket plates fixed on the side of the ship and adapted to receive corres onding flat pins provided on the lower end of the guide bars e. This method of attachment is preferable because the vertical bars e, as also the frame itself, can only be advantageously placed on the outside of the ship when she is discharging or taking in cargo. For this purpose the guide bars e require to be attached at top and bottom only. If they are fixed in the above mentioned sock- 208,373, and in Germany April 25, 1927.

ets at the bottom, the attachment 'at the top to the u per deck of the ship does not present the slig test technical difiiculty. The guide bars may be lifted into position with the aid of the ordinarily existing ships tackle and crane devices, in which case special eyes for the attachment of the crane hooks of the hoisting car may advantageously be provided toacilitate guiding into position the load-raising platform or the various parts thereof.

A lifting tackle f attached above the guide frame enables the above described platform for raising the load to be moved up and down vertically with aid of a Windlass (one of the ordinary ships winches or a special winch provided for this purpose), so that, with the aid' of this platform the goods can be raised from the level of the quay to the level of the upper deck of the ship without any risk of their being damaged and they may then be easily transferred on to the deck. Valuable goods, such as motor cars for example, are run horizontally from the quay on to the ,plaform, are then raised vertically without 7 swingin movement of any kind to the deck of the s ip andrun (again horizontally) on .to the ships deck whence they can be transferred without damage (by means of the apparatus described in a prior application Ser.

No. 67,897) to the hold of the vessel and securely stowed therein.

As stated, the platform can be removed from the outside of the ship. while the latter is in motion; thus, for exam 1e, it may be turned down, together with t e upper arts of the guiding device, on tothe dec as shown in Fig. 1. For this purpose the platform must be made to fold at c with the upper part of the guiding device and the supporting arms d must also be capable of being detached. or collapsed. The guide bars, as

already explained in detail above, may be wholly or partially detachable from the side of the ship andcan be hoisted by the ordinary 96 siiips loading gear on to the deck and stowed t ere.

The details of construction may be modified in many and various ways without departing from the fundamental idea of the in- 1 0 t and vice versa, and means permitting vention, which consists in attaching to the side of a ship a loading platform similar in construction to a lift and adapted to move vertically.

It is, further, obvious that the means for attachin the loading platform may be so arrange that they -can be applied at various points on the outside of the ship, according to the nature of the place where she isbcrthed for the time being, while, if necessary, the entire structure may be arranged, to slide along the ships side, for the purpose of locating it at the desired point on the ship accordin to the position of her berth-and 1 how she appens to be lying.

, All these modifications are easy to carry I out when the idea on which the invention is based is explained and all ofthem are to be understood to fall within the scope of the present invention.

The platform ma be so constructed that the goods to be loa' ed can be brought onto the platform at right angles to the central lane of the ship and it-may also obviously e so constructed that the goods to be loa ded can b'ebrought on to the said platform in a direction parallel to the said central plane. No difference in the use of the invention is occasioned thereby. 30. In the drawings the first mentioned constructional form of the invention is shown, that is tosay, the frame I) may be opened such as to allow the load to be brought on to the platform a at right angles to the central 85 plane of the ship.
