SPECIFICATION forming part of Letters Patent No. 629,554, dated July 25, 1899.

To @ZZ whom t may concern:

Be it known that I, FRANKLIN P. EAs'rMAN, of the city of New York, borough of Manhat tan, in the county and State of New York, have invented a new and Improved Dumping- AScow, of which the following is a full, clear, and exact description.

The invention relates to dumping-scows, such as shown and described in the Letters Patent of the United States No. 359,012, granted to me on March 8, 1887.

The object of the present invention is to provide a new and improved dumping-scow arranged to facilitate the dumping of all kinds of material, especially house and street refuse and the like.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is tobe had to the accompanying drawings, forming a part of this specitication, in which similar characters of reference indicate corresponding parts in all the iigures.

Figure lis a plan View of the improvement with parts broken out. Fig. 2 is a side elevation of the same with parts broken out and parts in section. Fig. 3 is an enlarged transverse section of the improvement on the line 3 3 in Fig. l. Fig. 4 is an enlarged face View of part of the improvement, showing the locking 'device for the side; and Fig. 5 is a transverse section of the same on the line 5 5 in Fig. 4.

The improved dumping-scow is provided with a suitably-constructed framework A, to which are attached the bottom Band the inclined floors O, forming a peak-shaped section extending centrally and longitudinally from one end D of the scow to the other end D', as is plainly indicated in Figs. l and 2. One or more bulkheads E may be arranged on the` side of the scow to give the desired strength to the structure.

On the lower outer end of each floor O are arranged pivots F, on which are hung arms G, normally extending vertically to support at their upper outwardly-curved ends the sides II, extending from one end D to the other, so as to form with the ends and the inclined floors compartments on each side of the scow. The connection between the arms G and the sides II is by means of pivots, so that when the arms G are swung outward, as indicated, in dotted lines in Fig. 3, then the sides II move with the arms and hang verti cally therefrom, owing to their Weight, to permit the contents of the scow to slide down the inclined bottom O into the surrounding water.

In order to keep the sides H and arms G in a vertical or closed position, as illustrated in full lines in Fig. 3, I connect the sides with a pair of transversely-extending ropes or chains I, extending through openings in the door O to the inside of the framework and passing over fixed bearings or guides J to then connect with a longitudinally-extending rope or chain I', attached to the piston-rod of a hydraulic or other ram K of any approved construction and located at or near one end of the scow. When the piston of the ram is in an outermost position, the sides H are closed, and when the motive power for the ram is permitted to escape therefrom then the sides H and the arms G are free to swing outward by the pressure of the load resting against the said sides H.

In order to lock the free or lower ends of the sides H in place while loading the scow and transporting it to a place of discharge, I provide locking devices L, each comprising a hook L', fulcrumed on the lower end of the corresponding door O and adapted to be en gaged by a locking-plate L2, having an elongated aperture through which is adapted to pass the outer end of the hook. The lockingplate L2 is fitted to slide vertically in suitable bearings L3, (see Figs. 4 and 5,) attached to the corresponding side H, and the said plate is hung on a rope L4, extending upwardly and passing over a pulley L5. The several ropes L4 for both sides connect with a rope L, leading to a capstan, windlass, or other similar winding apparatus i'or windin g up or unwindin'g the rope or chain L6 to raise or lower the several plates L2 simultaneously. The hook L of each locking device also extends through an opening in the corresponding side I-I and is adapted to normally rest on a projection L7, attached to the corresponding floor O. When the side I-I is in an open position, the hook L rests on the projection L7, and when the arms G swing inward and carry the side along then ICO the hook passes through the opening` in the Vside and that of the locking-plate L, and

when the side has reached its innermost position then the rope L is wound up on the windlass or capstan N, so as to draw the plate L2 upward and swing the hook L into alocking position to securely fasten the free end of the side -in place. Now it is evident that when the sides are closed the scow can be readily loaded with Ahouse and street refuse `and the like and then towed to the place of dumping, and when the place is reached the operator unlocks `the sides I-I by reversing the wiudlass N to allow the rope L6 to unwind and the plates L2 to drop and disconnect the hooks L from the sides H. The sides H are now free to swing outward with the arms Gr as a fulcrum, and the operator now permits the motive agent in the ram K to discharge, so that the arms G are free to swing outward, carrying the sides H with them into the position indicated in dotted lines in Fig. 3, so that the contents of the scow can readily slide down the inclined floor C into the surrounding water. By the arrangement described no obstruction in any shape or form is left for the refuse to cling to after the sides H are opened, soA that a complete discharge of the entire load takes place.

It is understood that house and street refuse when loaded, for instance, on a scow of the construction shown and described in the, pat-ent above referred to is liable to cling tosides, and arms ou which the sides are hung, said arms being pivotcd tothe scow, substantially as shown and described.

2. Adumpiug-scow, provided with movable sides, arms on which the sides are hung, said arms being pivoted'to the scow, and a locking device for locking the sides in place on the scow, substantially as shown and described.

3. A dumping-scow provided with an inclined floor, arms pivotcd at or near the lower, outer ends thereof, and a side hung on the upper ends of the said arms and adapted to form a compartment with the door and the ends of the `scow when closed, substantially as shown and described.

4. A dumping-scow provided with an `in-V clined floor, arms pivotedator near the lower, outer ends thereof, a side `hung on the `upper ends of the said arms and adapted `to form a compartment with the licor and .the ends ,of the scow when closed, and means for permitting a swinging motion to ,the said arms to allo7 the sides to open or close,'substantially as shown and described.

5. A dumping-scow provided with an inclined Iioor, arms pivoted at or near the lower, outer ends thereof,a side hung on the upper ends of the said arms and adapted to form a compartment with the `iioor and the ends of the scow when closed, means for .permitting a swinging motion to the said arms to allow the sides to open or close, anda locking device under the control of ,the operator, for fastening the lower, free end of the side to the scow at the lower outer end of the `correspondin g floor thereof, substantially as shown and described.
