APPARATUS FOR UNLOADING SCOWS.

SPECIFICATION forming part of Letters Patent No. 716,105, dated. December 16, 1902. Application 'filerl April 28. 1902. Serial No. 104,968. (No model.)

To all whom it mayooncern:

Be itknown that I, JESSE W. RENO, a citizen of the United States of America, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Apparatus for Unloading Scows, of which the following is a specification.

My invention relates to improvements in apparatus for unloading and dumpingflatboats or scows, such as are used for the transportation of dirt, garbage, and the like, where such material is to be thrown overboard, either for the purpose of filling in or making a convenient disposition of Waste matter.

. The object of my invention is to produce an apparatus whereby scows, flat-boats, and the like, which are used to convey material which is to be thrown into the sea, may be unloaded more expeditiously and at less expense than by the method or with the apparatus heretofore used.

My invention consists in arranging a series of pipes in close proximity to the deck on which the material of such boats is carried, in providing jet-nozzles in the pipes, and in providing means for forcing under considerable pressure a stream of Water through said pipes and jet-nozzles, and thereby washing said material overboard. 7

My invention consists, further, in subdi viding the deck of the scow into compartments, which compartments are provided with pipes, as aforesaid, and are controlled independently of each other.

In many large seaboard cities it is a practice to convey garbage and waste material on the deck of flat-boats or scows out to the sea and throwing such material overboard. It is also common to convey dirt forthe purpose of filling in such places, as where docks are to be erected and the like, with dirt, gravel, (he. 7 In all of thes'ecases the method now in use for unloading such material is by means of an ordinary shovel, which is laborious, slow, andexpensive.v

By means of my improved method and apparatus scows may be unloaded in a relatively short time and with a relatively small expenditure of labor.

In the drawings accompanying and forming part of this specification, Figure 1 represents a plan view of a scow provided with one form of my apparatus. Fig. 2 represents an end view. Fig. 3 represents a partial cross-section on line a a of Fig. 1. Fig. 4 represents a partial longitudinal section through the center line of the scow. Fig. 5 represents an enlarged view of a portion of one of the pipes 12, showing one of the jetnozzles therein.

The reference characters are used in the same sense in all of the figures of the drawings and the specification.

Numeral 1 represents the main deck of a seow or a flat-boat. The deck slopes from the center downward toward the outside edge or gunwale and is divided into the transverse compartments 2 by means of the transverse partitions 3.

Numeral 4 represents longitudinal pipes arranged along the apex of the deck, the length of each pipe being substantially the width of the compartment in which it is placed.

5 represents a longitudinal pipe or main connected with the pump 6 and connected with each of the pipes at by means of a vertical connection 7, provided with a valve 8.

9 represents transverse branches connected with the longitudinal pipes at.

10 represents slots or jet-nozzles in the longitudinal pipes 4 and branches 9, which direct the water from said pipes and. branches onto the deck of the boat.

11 represents hinged sides to the boat, which are preferably made in sections of a length equal to the width of the compartments 2. These hinged sides are locked in place, as shown in Fig. 2, in any convenient manner and serve to increase the carrying capacity of the boat. Preparatory to unloading they are unlocked and let down, as will be readily understood.

The material carried by boats of the class to which this invention applies is not usually homogeneous, and when the Water is turned on the material from one side may be carried away earlier than that of the other side. If this were to take place during the whole length of the boat, it would be likely to capsize, and to prevent this I divide the deck into compartments or segments of such size that it would not materially efiect the stability of the boat should all the material from one side of the segment be removed before any of that on the other side, and by means of the valves 8 I am enabled to operate one or more segments at a time and to discontinue the operation of any segments at any time, as required.

Having thus described my invention, what I claim is- 1. In an apparatus for unloading scows, the combination with a deck adapted to carry loose material, of a pipe extending along the surface of said deck, jet-nozzles in said pipe directed toward the outer edge of said deck, and means for forcing a powerful stream of water through said pipe and j et-nozzles whereby said material is swept overboard.

2. In an apparatus for unloading scows, the combination with a deck, of transverse partitions dividing the deck-surface into transverse segments, pipes provided with jet nozzles or openings located on each segment, and means of forcing water through the pipes of one or more segments at a time.

3. In an apparatus for unloadingscows, the combination with a deck adapted to carry loose material inclined from its longitudinal center line downward toward its outer edge, of a pipe located near and parallel to said longitudinal center line, jet-nozzles in said pipe, and means of forcing water through said pipe and said jet-nozzles, whereby said material may be washed overboard.

4. In an apparatus for unloading scows, the combination with a deck inclined from the center downward toward its outer edges, of transverse partitions extending above the surface of said deck, dividing it into compartments, a pipe extending along the ridge of each compartment, having branches at its ends extending parallel to said partitions, jetnozzles in said pipes and branches, a longitudinal main, and independent connections between said main and the pipes of said compartments.

5. In an apparatus for unloading scows, the combination with the deck 1, of the partitions 3, the pump 6, the main 5, the vertical connections 7 having the valves 8, and the pipes 4 and 9 provided with the jet-nozzles 10, and communicating with vertical connections '7.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JESSE W. RENO.
