` DUMPINescoW.

Specification of Letters Patent.

Patented July 1s, 1909.

Application filed July 1, 1908. Serial No. 441,274.

To all whom t may concern: l

Be it known that I, FRANKLIN P. EAST- MAN, a citizen of the United States, and resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Dumping-Scow, 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. 629,554, granted to me July 25, 1899.

The object of the present invention is to provide a new and improved dumping scow, having movable` sides normally securely locked against opening, and which can be readily opened without presenting obstructions to the load, thus insuring a complete and quick discharge of the load, especially when the latter consists of bulky and moist refie liable to cling to any obstructions in its )at l The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a plan view of a dumping scow having two pairs of compartments, of which one pair is shown closed and the other open; Fig. 2 is an enlarged cross section of the improvement on the line 2 2 of Fig. l; Fig. 3 is a similar view of the same on the line 3 3 of Fig. l; and Fig. Il is a like view of the same and showing one of the sides partly open.

To the framework A of the dumping scow is attached a bottom B and inclined floors O, C, forming a peak-shaped section eXtending centrally and longitudinally from one end D of the scow to the other end D thereof, as plainly indicated in Figs. l and 2. One or more bulkheads E may be arranged transversely on the scow, to give the desired strength to the structure and to form with the floors O and the movable sides F, com partments for receiving the refuse, each compartment having a side or door F which can e opened for allowing a load to slide down the corresponding lioor O into the water.

The lower ends of the sides F are adapted 4to engage hooks or similar retaining devices G attached to the lower ends of the floors O, and the upper ends of the sides F are pivoted on transversely extending supports H in the form of beams mounted to slide in suitable bearings arranged in the upper portions of the floors O, as plainly indicated in Figs. 2 and 3. The inner ends of the supports H are provided with racks H and the supports H of two oppositely arranged sides F having their racks H in mesh with opposite sides of pinions I secured on a shaft J extending engthwise of the scow and journaled in the framework A immediately below the ridge of the peak-shaped section, as plainly indicated in Figs. 2 and 3. In practice, I prefer a shaft J for each pair of compartments and each shaft J is provided at one outer end with a suitable turning device K, such as a pawl and ratchet mechanism, as indicated in Fig. l.

Arms L are pivotally connected at their lower ends to the lower ends of the floors O, and the upper ends of the said arms L are pivotally connected with the supports H a distance inward from the pivotal connection of the sides F with the supports H, as plainly indicated in Figs. 2 and Now when the sides F are closed, as shown in Fig. 2, then the compartments thus formed can be iilled in the usual manner, and when it is desired to discharge the load, it is only necessary for the operator to turn the corresponding shaft J, by actuating the ratchet mechanism K connected with the shaft, so that the pinions I im art an outward traveling motion to the rac rs H and to the supports H. N ow during this outward travel of the supports H, the arms L swing outward and thus lift the outer ends of the supports H slightly and with them the sides F, which also assume an inclined position, as shown in Fig. 4, the lower ends of the sides F finally leaving the retaining devices G, to swing into an open position, as indicated. in Fig. 3. N ow when this takes place, the load in the opened compartments readily slides down the inclined floors O into the water surrounding the scow. By the use of the supports H andthe arms L the sides F can be readily swung into an open position, without requiring much physical exertion on the part of the operator turning the shaft J, so that practically it requires but little help to move the sides F into an open position for dumping the load of the scow. K It will also be noticed th'at the load is discharged simultaneously from both sides of the scow, as. the corresponding sides of a pair of compartments open at the same time. By turning the shaft J in an opposite direction the supports H are moved inward, to allow of closing the sides F, whenever it is desired to refill the compartments of the scow with another load.

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

l. A dumping scow provided with movable sides, transversely movable supports on which the said sides are hung, and links pivotally connected with the scow and pivotally connected with the said supports at a point inward from the connection of the said sides with the said supports.

2. A dumping scow provided with movable sides, transversely movable supports on A the outer ends of which the said sides are hung, retaining devices on the scow for engagement by the lower ends oi the said sides, links pivotally connected at their lower ends with the said scow at the lower end of the lioor and pivotally connected at their upper ends with the said supports at a oint in-. ward of the pivotal connection of t ie sides, and means for imparting an outward movement to the supports, to cause the links to swing outward thereby lifting the outer ends of the sup orts and the said side to release the latter trom the retaining devices.

3. A dumping scow provided with an inclined floor, transversely movable supports on the scow, a side hung on the said supports, retaining means iiXed on the lower end of the said floor and adapted to be engaged by the lower free end of the said side, and

arms pivotallyl connected with the scow, and with the said supports,` the connections of said arms with the supports being inward of the connection of' the side with the supports, and the said arms inclining inwardly when the side is in closed position, whereby when the supports are moved outwardly the outer ends of said supports are lifted to'disengage the side from the retaining means.

4. A dumping scow provided with an inclined floor, transversely extending supports provided with racks, a shaft extending lengthwise 6i the scow, pinions on the said shaft and in mesh with the said racks, a side hung on the outer ends of the said supports, and arms pivotally connected with the scow at the lower ends of the said floor, and pivotally connected with the said supports a distance inward from the connection of the said side with the said supports,

5. A dumping scow provided with an in-V clined floor, transversely-extending supports provided with racks, a shaft extending lengthwise of the scow, pinions. on the said shaft and in mesh with the said racks, a side hung on the outer ends of the said supports, arms pivotally connected with the scow at the lower ends of the said lloor, and pivotally connected with the said supports a distance inward from the connection of the said side with the said supports, and hooks on the lower end of the said ylloor and adapted to be engaged by the lower end of the said side.

6. A dumping scow provided with inclined l'loors, transversely extending supports mounted to slide in bearings in the upper portions of the floors, sides hung on the outer ends of lsaid supports, arms pivotally con-4 nected with the lower ends of said lloors and pivotally connected at their upper ends with the said supports, the connections of said arms with the supports being inward of the connection of the sides with said supports, a shaft extending lengthwise of the scow and journaled in the framework, and means for imparting a traveling motion to the said supports from the said sh alt.

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

FRANKLIN I. EASTMAN.
