THOMAS SPENCER MILLER, OF SOUTH ORANGE, NEW JERSEY.

CONVEYING APPARATUS.

Specification of Letters Patent.

Patented Aug. 25, 1908.

Application led January 16, 1904. Serial No. 189,279'.

To all whom it may concern:

Be it known that I, THOMAS SPENCER MILLER, a citizen of the United States, and a resident of South Orange, county of Essex and State of New Jersey, have invented a new and useful Improvement in Conveying Apparatus, of which the following is a specification.

The primary object of my invention is to provide means whereby the material may be transported from the land to the point of construction of a breakwater, but it possesses, also, capability for useful application for other purposes.

In the accompanying drawings, Figure 1 represents an ap aratus containing my invention rigged for the construction of a breakwater. Fig. 2 is a plan view of the same. Figs. 3 and 4 are side and plan views of the boat. Figs. 5 and 6 show two forms of the marine rope-carriers with a bow end view of the boat. y

In the drawings, Figs. 1 and 2, the material is being transported from cars 1 on the railway tracks 2 on land, to the water line 3 and thence across the water to a dumping point above the foundation 4 which is being built` for a breakwater.

A derrick 5 is employed for transferring the material from the cars on each track to a boat in which the transportation is effected.

Each of the boats is preferably of the form shown in Figs. 3 and 4 consisting of a hull 6 so decked over as to form a water-tight air compartment which, by reason ofstrength of exterior construction and internal bracing, is capable of standing all of the shocks to which it may be subjected by the waves. The bottom of this boat is provided with the rollers 7 capable of supporting the boat and its load and acting as wheels for the same during its passage over the ground to the water line. 8 and 9 are two boxes or trays which are hinged, respectively, at 10 and 11, to the gunwales of the boat and which, in carrying position, rest in what is substantially a cock-pit in the deck above the airtight deck 12 and between the fore and aft air-

tight decks

13 and 14. A stand 15 projects -upward from the deck 12 between the

trays

8 and 9. On opposite sides of such stand at the top, are secured the

sheaveblocks

16 and 17.

Fingers

18 and 19 are fixed to the rear of the trays, respectively, and in cooperation with the stops 20 and 21 limit the extent to which the rear of the j trays may be raised to the dumping position shown in Fig. 5.

The rope mechanism by which the boats are propelled may, for each boat, be described as follows: 22 is a rope-drum engine containing the friction-rope-

drums

23 and 24. 25 is a raft anchored beyond the dumping point. A rope extends substantially from the drum 23 out to the raft and back again to the drum 24, so that by the operation of the two drums the rope can be caused to travel in either direction, or be held stationary, and can be drawn tight or be permitted to slack. The various runs of this rope may be described as follows: Run 26 extends from drum 24 to a sheave at 27 at the head of mast 28. Run 29 extends thence to the sheaves 30 on the raft. thence to the boat where it is made fast on both sides the bow thereof, as shown inFigs. 3 and 4. Run 32 extends from the drum 23 to a sheave at 27 at the head of the mast 28. Run 33 extends thence between the guide-

sheaves

34, 35, on the out-rigger 36 projecting from the stern of the boat to the' splice 37. Run38 extends thence over the sheave 16 to the rear of the tray 8 where it is made fast. Run 39 extends from the splice 37 over the sheave 17 to the rear of the tray 9 lwhere it is made fast.

In Fig. 2, there are 16 marine rope-carriers shown, four for each rope. Each of these rope-carriers may be either of the form shown in Fig. 5 or that shown in Fig. 6, which are essentially the same excepting that one is su ported by the bottom and the other by oats. Each of these rope-carriers contains an

iron frame

40, 41, 42 and 43, through which the boat is adapted to pass. Each also carries a submerged sheave 44 to serve as a rest for either rope-

run

31 or 33, depending upon the position of the boat. The

inclined braces

45 and 46 serve to direct the rope into the groove of the sheave 44. 47 is a submerged sheave on which the rope-run 29 is retained by the clevis 48.` The ropecarrier shown in Fig. 5 is supported by the legs or spiles 49 and 50 which are driveninto the bottom. The rope-carrier shown in Fig. 6, is supported by the floats 49a and 50a. At the

eyes

51 and 52, the rope-carriers are connected with each other by the longitudi nal

guys

53 and 54, each of which guys has one end connected' with the raft and the other with an anchorage 55. Each ropecarrier also has an anchorage of its own se- Run 31 extends',

i cured to the

eyes

51 and 52 preferably by a yielding connection, such as the spring 56 or the counterweight 57, and sheave 58. Where several rope-carriers are used abreast, as shown in Fig. 2, the two outside ones only need have separate anchorages ,their adjacent sides being connected by the connecting guys 59.

The operation is as follows: A boat resting upon its wheels on the shore is loaded from the cars by means of the derrick. The clutch of drum 24 is thereupon set while drum 23 is permitted to pay out under its brake. The boat is thus towed on its wheels by rope-run 31 down to the shore line 3 and thence floated by the Water it is towed through the successive rope-carriers to the point of dumping. Thereupon the brake is set on drum 23 so as to hold back on rope-run 33 with suflicient power to lift the inner ends of both the trays and cause them to dump, as shown in Fig'. 5.

In order that the trays shall not be prematurely dumped, the strain upon the ropes required for dumping must be in excess of the maximum strain incident to the outhauling of the rope 33 by the out-hauling of the boat, which required strain is reduced to a minimum by the rolling support afforded by the sheaves of the marine rope-carriers. The distribution of these marine rope-can riers will, therefore, be dependent upon the depth of water; it being required that they should be nearer together in shallower water in order to prevent the rope from contacting with the bottom.

Although I have shown this apparatus as applied to the construction of an off shore breakwater, I do not wish to be understood as so limiting myself, because I am aware that it may be used between two ioating objects at sea or for carrying material from a floating object ofi shore to the shore. Nor do I limit myself to a single boat nor to the reciprocating movement of the rope as distinguished from a continuous lmovement in the same direction of the rope to which the boat is attached.

IIaving thus described my invention, I claim as new and desire to secure by Letters Patent:
