SPECIFICATION forming part of Letters Patent No. 643,064, dated February 6, 1900.
Application filed November '7, 1899. Serial No. 736,125. (No model.)
To all whom it may concern.-
Be it known that I, EDWIN KERSHAW, a citizen of the United States, and a resident of Wilmington, Delaware,have invented certain Improvements in Dumping-Scows, of which the following is a specification.
The object of my invention is to so construct a dumping-scow that heavy loads of dredged spoil may be dumped into the same from the dredging-bucket or otherloading device without injury to the scow or to the dumping-gates at the bottom of the same; and this object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in Which Figure 1 is a top view of a dumping-scow made in accordance With my invention, and Fig. 2 is a transverse section of the same on a larger scale.
In modern dredging operations buckets of large capacity are employed, and an ordinary dumping-scow having hinged dumping-gates at the bottom is incapable of withstanding the impact of the heavy masses of solid matter dumped into the scow from a point above the same and over the gates. Hence it is customary to lower the bucket or other loading device into the scow from one side or the other of the same; but the descent of the bucket cannot always be checked at the proper time, and holes are frequently knocked in the bottom of the scow by the forcible contact of the heavy bucket therewith. In order to overcome these objections,l provide the scow with a shield or guard running centrally along the top of the same from end to end of the compartment structure of the scow, so that the load of spoil dumped from a dredging-bucket or other loading device first strikes this guard or shield after a short fall and is divided and deflected thereby, part of the load passing into the scow on one side of the same and part on the other side. Hence both the volume and extent of drop of the load are reduced, and any such forcible impact of the spoil upon the bottom gates as would tend to force the same open or cause injury to them is effectually prevented.
In the drawings, 1 represents the hull of the scow, and 2 the tapering or hopper-like compartments into which the same is divided by means of transverse partitions 3, each of the hoppers being closed at the bottom 'by means of a pair of swinging gates i, the hinges of which are hung by chains 5 to cleats 6 on the sides of the hopper, the gates being operated by means of achain 7, which passes over a guide-pulley 8 and is operated by a capstan 9, mounted upon one of the gunwales -10 of the scow.
On the top of the scow, above the gates 4, is the guard or shield 11, which consists of aseries of beams 12, extending throughout the length of the compartment structure of the scow and mounted upon the partitions 3, whereby the compartments or hoppers 2 are separated one from another, these beams carrying the inclined deflecting-timbers 13, which are preferably provided with metallic sheathing 14. in order to prevent injury thereto in case the shield or guard is struck by the bucket. I
When the scow is constructed as thus described,loads of the largest size can be dumped into the same without risk of'injury to the gates 4 or other portions of the scow, since the falling load cannot exert its impact directly upon the dumping-gates, nor is it necessary to lower the bucket or other loading device down into the scow before dumping the same, thereby not only preventing injury to the scow, but also saving considerable movement of the bucket and eifecting a corresponding economy of time in the operation of the latter.
Having thus described my invention, I claim and desire to secure by Letters Patent 1. A dumping-scow having dumping-gates at the bottom, and a guard or shield located above the said gates and extending longitudinally throughout the scow, said shield receiving the initial impact of the load of spoil discharged from the dredging-bucket or other loading device, substantially as specified.
2. A dumping-scow having dumping-gates atvthe bottom, and having, above the same, a shield or guard which extends longitudinally throughoutthe scow, receives the initial impact of the spoil discharged from the dredge-bucket or other loading device, and is inclined downwardly from the center toward each side so as to divide the load and deflect it to opposite sides of the scow, substantially as specified.
3. A dumping-scow divided by transverse partitions into a series of compartments or hoppers, each having dumping-gates at the bottom, said partitions serving to support a longitudinal shield or guard located above the dumping-gates and serving to receive the initial impact of the load of spoil discharged from the dredging-bucket orotherloading de- 10 Vice, substantially as specified.
In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
EDWIN KERSIIA'W.
