VESSEL-TRIMMER.

Specification of Letters Patent.

Patented April 10, 1906.

Application filed November 16, 1904. Serial No. 232,941.

This invention is generically a vessel-trim ming apparatus, but is especially constructed forfuse in connection with the loading of coal onto such vessels as sail on the Great Lakes. The docks where such vessels are loaded are usually provided with car-dumping machines which lift a loaded coal-car to a suitable height.

and then tip it over, so as to dump out the load onto an inclined apron. The coal slides down this apron into a vertical tube attached thereto and extends down into the hold of the vessel. in the bow underneath the cabins, which has not heretofore been utilized for carrying coal.-'

It is to level or trim the coal so loaded into the hold that the present invention is designed; but it is particularly adapted for dragging such coal into a space in the bow beneath the cabins which has not heretofore been utilized. It is also useful for breasting a vessel out from the dock to get it into suit-; able position for effectively loading it Wltli the appliances on the dock provided for that purpose.

In the drawin s, Figure l is a side elevation of my improved apparatus and a sectional view of a'vessel with which it is being used.

The View also shows in dotted lines and more or less diagrammatically a car-dumping machine, one of the posts of this machine being utilized as a support for the boom which forms parts of the present invention. Fi 2 is an enlarged plan view of thedock enc of said. boom and a horizontal sectional view of the supporting -post. Fig. 3 is a sectional side view of a beam clamped upon the hatchcoaming of a vessel and carrying lead-sheaves for the purpose hereinafter described. Fig. 4 is a plan view of a forward end of a vessel and of my apparatus in operative relation thereto. Fig. 5 is a vertical longitudinal sectional view of the parts shown in Fig. 4. Fig. 6 is a view similar to Fig. 4, but showing the boom in a difierent position. Fig. 7 is a detached view of one of the fore-and-aft lead-blocks,

showing the means for detachably connecting it to a stanchion or some other beam in the cables for sustainin In such vessels there is a large space spective view of one of t may be used.

The invention, as shown, includes a b om e scrapers which hinged to a supportin -post on the dock,

which post is preferab y one of the comerposts of a car-dumping apparatus, said boom being adapted to overhang the deck of avessel,

the outer end of said boom in the require position, a trolley movable upon said boom and adapted to be fixed thereto at a suitable point, sheaves upon said trolley, a reversible motor and winding-drums.

supported on the dock (in contradistinction hold of the vessel; and Fi 8 is a small perto being supported on the vessel) lead-blocks.

for attachment in the hold of the vessel at;

and at two points which are respectively orward and aft said.

points below said trolle points, cables secured to said drums and assing over said sheaves and through said eadblocks, and scrapers attached to the cable between the foreandaft lead-blocks referred to.

The invention consists in such combinations of the parts above referred to as definitely pointe out in the claims.

Referring to the parts by letters, A represents a substantial post on the dock X. This post is preferably one of the posts of a cardumping machine or of. some other appara us which is useful in the loading of a vessel.

B represents a boom which is connected with said post by means which may be raised and lowered in accordance with the height of the vessel and which permits the boom to swing both vertically and laterally. In the construction shown a vertically-movable slide B is mounted in grooves on the front of the post and is supported and raised and lowered by a cable T. A piece B is pivoted to said slide on a hollow vertical ivot b, and the boom is pivoted to this piece 2 on a horizontal pivot. The outer end of the boom is sustained by a cable O, which cable extends over the sheave c on top of the post and down to suitable mechanism (not shown) for taking it in and paying it out.

The boom consists of two parallel beams b b, which serve as tracks for a trolley E, on which the guide-sheaves e e are mounted. This trolley is movable on the boom; but

when it has been-moved to the desired posi- I tion it must be secured thereto a ainst further movement during the operation of the device. Any suitable means may be em- IIO ployed for so securing the trolle to the boom.

A motor F and a reversible s aft D, driven thereby, must be lprovided and must be supported on the doc either directly or through the intervention of some device which is supported upon the dock. By preference these parts are supported on the slide B, as shown in the drawings; but it will be understood that this is not essential. On shaft D are two drums H G, one of which should be connected with said shaft by a clutch J. When m use, operating the scraper backward and forward, both drums are fixed to the shaft; but when it is desired to lengthen or shorten the cables K K it is necessary to be able to disconnect one drum from the shaft.

The ends of the cables K K are attached to said drums, respectively, and are wound thereon in opposite directions. The cables pass up through'the hollow pivot I), over a roller y, mounted on iece B, and over the sheaves e e on the trol ey and down into the .hold of the vessel L. In the hold and at points approximately beneath the trolley E two lead-blocks N N are secured. Two other lead-blocks M M are fixed in the hold, one bering forward and the other aft of the leadblocks N 'N One cable goes from block N to and around one of these blocks M, and the other goes from block N to and around the other block M, and a scraper P is attached to both cables between the two blocks N and N. By Winding up one cable the scraper will be drawn in one direction, and by winding up the other cable the scraper will be drawn in the other direction. The coal will be scraped in that direction in which the nose of the scra er is turned and carried as far as desire The scraper employed should be one which When drawn backward will tip sufficiently to dump its load. This result may be attained by emplo g a scraper substantially as is shown an h dnnecting it in the manner shown to the cables. This scraper has upwardlyextended sides, to which is attached the forwardly-extended bail p, which is connected with said sides a substantial distance above the bottom. Another bail p extends rearward from the scraper and is connected therewith close to the bottom. The cables K K are connected with these two bails. When the scraper is pulled by the rear bail, the rear end of the scra er will be raised until the points at which oth bails are connected are m the same horizontal plane, and this lifting of the rear end of the scraper is enough to cause the load to run out. A flexible connection may also be made between front bail p and the top of the scraper. The cable K will draw the scra er forward in a suitable position for doing effective work.

B changing the position of the trolley on the hoom and of the lead-blocks in the hold the range of the scraper may be extended entirely across the vessel from side to side. The lead-blocks may be secured at any position in the holds-as, for example, they may besecured at the front end of that space Q beneath the cabins which it is desired to fill with coal.

The lead-blocks M M or one of them will be covered with coal, and therefore inaccessible when the apparatus has done its work. It is, however, necessary to remove this, and for this purpose they are each connected with a chain W, on one end of which is a hook 9, having a lever-arm 10 to which a cablew is attached. The chain is passed around a stanchion or horizontal beam, and the hook is made to enga e with a link w. A cable e12 is connected with the leverarm 20 and is carried to a point where it will always be accessible. When it is desired to remove the described block, the cable w is pulled upon until the hook is in such position that it will disengage itself from the hook.

The capacity of the boom to swing sidewise is of advantage for two reasons-via, it may be drawn out of the way of the upper works of avessel about. to be docked. It also adapts the cables to work through three or more hatchways without moving the vessel. For example, as shown in Fig. 6, the boom extends over the vessel at an angle of about thirty degrees to the dock-front. As shown, the boom is not long enough for the cables to come strai ht down therefrom through the hatches. nder such conditions a beam R may be clamped on the hatch-coamin and may carry lead-sheaves 1" 1", over whic the cables run.

In the loading of vessels with the kind of machinery to be found on the docks for this purpose it is generally necessary to breast the vessel away from the dock, so as to distribute the infiowing car 0 more evenly. This is usually accomplished by means of wedges drawn in between the dock and the vessel. The described mechanism, however, may be employed for this purpose and will move the vessel out from the dock in a very much shorter time than any mechanism heretofore employed. To use it for this ur ose, one of the cables is drawn u from the hold and is then connected with t e dock side of the vessel, said cable passing from this point up to the sheave e on the trolley, as indicated b dotted. lines in Fi 1. By winding up this cable the vessel wi 1 be breasted out from the dock to any extent required.

I claim 1. In a vessel-trimmer, the combination of a dock, a boom hinged to a device secured to the dock, means for sustaining the outer end of said boom, a motor, and a reversible shaft driven thereby, both of which are mounted upon some device which is supported u on the dock, two drums secured to said shaf f, a trolley movable upon said boom, lead-blocks mounted on said trolley, two lead-blocks secured in the hold of a vessel below one of the hatchways, other lead-blocks secured in the hold of the vessel and located respectively forward and aft of the lead-blocks first men' tioned, cables whose ends are wound in opposite directions upon said drums and which extend over the said lead-sheaves and around the blocks below the hatch, and which extend respectively around the forward lead-block and the aft lead-block, and a scraper connected with said cables, between said fore-and-aft lead-blocks.
