DUMPINGY-SCOW.

SPECIFICATION forming part OfLGttGrS PQtHt NO. 605,762, dated June 14, 1898.

Application filed November 20, 1897. Serial No. 659,262 (No model.) I

To ctZZ whom it ntay concern:

Be it known that I, NATT STIoKNEY, of Bradford, in the county of Essex and State of Massachusetts, have invented a new and Improved Dumping-scow, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved dumping-scow which is simple and durable in construction and arranged to permit a convenientdischarge of a load and an automatic return of the receptacle after the load is discharged, thus requiring little or no manual labor in the working of the scow.

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

Reference is to be had to the accompanying drawings, forming a part of this invention, in which similar characters of reference indicate corresponding parts in both the figures.

Figure 1 is a plan view of the improvement, and Fig. 2 is a sectional side elevation of the same.

The dumping-scow is provided with a body A of any approved construction and formed with a bottomless well 13, containing one or more receptacles 0, each hung at its ends on pivots D, secured to transverse beams or partitions E, as is plainly indicated in Fig. 1. Each receptacle 0, is made in the form of a scoop having the discharge end 0 extended such a distance from the pivot D that when loaded it overbalances the opposite side 0 and consequently the receptacle which receives a load while held in a horizontal position, as shown in Fig. 2, after being released swings automatically into a dumping posi tion, as indicated in .dottedlines in Fig. 2, to allow the contents of the receptacle to flow out over the discharge side 0 and "through the bottom of the well B into the water below. 'It will be understood, however, that when empty the receptacle 0 tends to assume the horizontal position shown in full lines in Fig. 2.

In order to hold the receptacle 0 in a normal or horizontal position, as shown in Fig. 2, I providethe top of the scow with a pivoted catch F, adapted to pass under the side 0, so

as to lock the receptacle in place during the filling thereof with the load and while the scow is carried to the place of dumping. When the dumping-place is reached, the operator simply turns the catch F to allow each receptacleto'swing into a dumping position, as previously explained, owing to the overbalancing weight on one side of the receptacle.

r The receptacle C can be locked in a dumping position in case the load is of a sticky nature and discharges slowly, and for this purpose'I provide'the bottom of the receptacle with teeth G, adapted to be engaged by a pawl H, fulcriimed to the top of the scow opposite the catch F. WVhen the receptacle swings into adumping position and the pawl H is thrown over. against the peripheral surface of the receptacle, then said pawl engages one of the teeth G to lock the receptacle in a discharging position..

The receptacle may be made of sheet metal or other suitable material, and the well may be lined with a similar metal, as indicated in Fig. 1.

Now it is evident from the foregoing that the load can be quickly discharged whenever desired, and after the material has left the receptacle the latter automatically returns to its former position and again passes under the catch F, which is swung out for this purpose to hold the receptacle in place during loading.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of the well widened at its top, and the dumping-receptacle mounted to turn in said widened portion and so arranged j that in the discharging position the .outlet of the receptacle is within the well and substantially at the lower end of the widened portion thereof.

2. A dumping-scow provided with a well, open at the bottom, a receptacle pivoted at its ends in the hold, and having its discharge side arranged to overbalance the opposite side, so that upon releasingthe receptaclefrom a normal position, it will turn automatically on its pivots into a dumping position and-discharge the load, and means, substantially as described, for locking the receptacle in a I means for locking the receptacle in the disdumping position, as set forth. charging position.
