AUGUST VON HOFFMANN, OF MUNICH, GERMANY.

SUBMARINE APPARATUS.

SPECIFICATION forming part of Letters Patent No. 664,152, dated December 18, 1900.

Application filed June 12, 1900.

To all whom, it may concern.-

Be it known that 1, AUGUST VON HOFFMANN, a citizen of Austria, residing at Munich, in the Empire of Germany, have invented certain new and useful Improvements in Submarine Apparatus; 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 make and use the same.

This invention relates to vessels for use in submarine operations that are anchored to the bottom of the sea, from which position the crew in the boat can operate on a sunken object.

The invention consists, broadly, in the arrangement of an endless chain or the like running around the vessel, pulleys attached to the chain, anchor-ropes that pass through the pulleys and then into the vessel and are secured to winding-drums, and means for moving the endless chain around the vessel in either direction, and in such other features of construction and arrangement, separately or in combination, as will be fully described hereinafter and particularly pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is a side elevation or a boat embodying my invention in my preferred form of construction and arrangement. Fig. 2 shows a front View. Fig. 3 illustrates the boat from a bottom View showing the turning arrangements. Figs. 4 and 6 show diagrammatically two different methods of turning the boat. Fig. 5 shows the turning apparatus in various positions. Fig. 7 shows in diagram the means for anchoring the boat.

My new diving-boat consists of a vessel shaped somewhat like a ship and is closed on all sides. It is divided lengthwise into three compartments, of which a is the chamber from which the work is performed on the object by means of tools passing through orifices in the sides, as is well known by those skilled in the art. The room a is connected with the rear room 1) by a corridor 0.

There are four anchors attached to ropes g, h, 1', and j, respectively, that are each wound upon a drum is is k 10 arranged two on each side of the boat, which drums can be operated by the crew of the boat. The securing of the Serial No. 20,086. (No model.)

boat by means of these several anchors may be effected in various ways. According to Fig. 7, as one example, the anchor gis dropped at a sufficient distance from the object at 1. Then the boat is moved to the position of 2, Fig. 7, and here the anchor h is dropped, whereupon the boat is moved diagonally across and at an equal height with 1 theanchorj is dropped at 3. Then the boat is further moved across to the point 4 of Fig. 7, where finally the anchor i is dropped. Then the boat moves to the middleof the rectangle made by these four anchor positions, (at the intersection of the diagonals in dotted lines,) whereupon by the winding up of the anchorropes upon their respective drums the boat is securely and immovably anchored. For the rotating of the thus-anchored boat the following arrangement is provided: On the outside of the boat an endless chain 12 or the like is carried, being supported and guided by suitable pulleys m, secured to the side of the boat, there being five shown at each end of the boat. One of these pulleys m has a bevel-gear attached to it, meshing with another gear on a shaft p, projecting through the boat, on the inner end of which is secured an operatinghandle, by which one of the crew may move the chain in one direction or the other. On this chain n are fixed four pulley-blocks 0 0 o 0 two on each side of the boat. Each of these pulleys has one of the said anchor-ropes passing through it after emerging through the hawse-hole of the boat.

The turning of the boat in either direction can be effected by the arrangement just described in two different ways. In one way two of the anchor-ropesfor instance, h and j, Fig. 4:constituting a diagonal of the said rectangle, are tightly stretched, while the other ropes g and 1 are slackened. Then by the means atp the chain is moved in the direction of the arrow, Fig. 4, and also the pulley o, 850., will move in the same direction. This will cause the pulley 0 to put the anchor-rope h under a greater tension, and also the pulley 0 will put the anchor-rope 3' under greater tension, while the other pulleys o and 0 will tend to relax the tension on the anchor-ropes g and i. The result of this is to cause the boat to turn, as on a pivot, to the position shown in the dotted lines in Fig. 4.

Then by tightening of the ropes g and i by their drums the boat is secured in this position. According to the diagonal position of the ropes and the amount of shifting of the chain a greater or less turning of the boatis effected. On the contrary, if the other anchorropes g and 1; are tightened and the ropes h and j slackened and then the chain moved in the other direction a turning of the boat is efiected in the opposite direction to that just described. As illustrated in Figs. 5 and 6, by this turning of the boat the hawse-hole 1*, through which passes the anchor-rope 7), describes part of a circle, while the pulley 0 on the chain for the same rope describes an elliptical track, and it will be seen that the pulley crosses the track of the hawser. Through this crossing, as the positions of the pulley at 2 and 3, Fig. 6, indicate, the angle given to the rope by the pulley changes from obtuse to acute.

By means of the above-described arrangement the crew of the boat is enabled to anchor the boat near the object and to change the point of attack on the objectin successive positions by simply manipulating the anchordrums and the chain-moving device, without which mechanism it would be necessary to raise the anchor, steer the boat sidewise, and again anchor the boat.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The combination with a vessel, and anchor-ropes extending fromseparate parts of the same, of means on the vessel for simultaneously changing the points of connection of the anchor-ropes with the vessel.

2. The combination with a vessel and a pair of anchor-ropes extending from the same on each side, means on the vessel for simultaneously changing the points of connection of the anchor-ropes with the vessel, and a winding means on the vessel for each anchor-rope.

3. The combination with a vessel, of an endless chain or the like, passing around the vessel, anchor-ropes extending from the vessel and connected with said chain, and means for moving the chain around the vessel in either direction.

4. The combination with a vessel, of an endless chain or the like, passing around the outside of the vessel and supported by pulleys at each end of the vessel, pulleys arranged on the chain on each side of the vessel, anchorropes extending from the vessel on each side each passing through one of said pulleys on the chain, and'means for moving the chain around the vessel in either direction.

5. The combination with a vessel, of an endless chain or the like, passing around the outside of the vessel and supported by pulleys at each end of the vessel, pulleys arranged on the chain on each side of the vessel, apair of anchor-ropes extending from the vessel on each side, said anchor-ropes passing through said pulleys on the chain, and means for moving the chain around the vessel in either direction.

6. The combination with a vessel, of an endless chain or the like passing around the outside of the vessel and supported by pulleys at each end of the vessel, pulleys arranged on the chain on each side of the vessel, a shaft extending through the side of the vessel at one end on which one of said pulleys is mounted, means for rotating said shaft inside of the vessel to actuate said endless chain, and a pair of anchor-ropes extending from the vessel on each side, said anchor-ropes passing through said pulleys on the chain.

In testimony whereof I aifix my signature in presence of two Witnesses.

AUGUST VON HOFFMANN.
