LOAD-TRIMMER.

Specification of Letters Patent.

Patented Sept. 29, 1908.

Application filed January 9, 1908. Serial No 409,937.

To all whom it may concern:

, Be it known that we, JOHN'T. JOHNSON and WILLIAM M. RAY, both citizens of the United States, and residents of Akron, county of Summit, and State of Ohio, and-Cleveland, county of Cuyahoga, and State of Ohio, respectively, have jointly inventeda new and useful Improvement in Load Trimmers, of which the following is a s ecification, the principle of the invention eing herein explained and the best mode in which we have contemplated applying that principle, so as to distinguish it from other inventions.

Our invention relates, as indicated, to loading apparatus and has particular regard to ap aratus of this character such as is used in oading vessels from elevators or the like, particularly in loading vessels with coal.

The object of the present invention is the provision of a discharge chute for use with such a paratus whereby the necessity of manual y trimming the load may be avoided thereb effecting a large saving in the cost of the lbading by the elimination of labor in the carrying on of this operation.

To the accomplishment of this and related objects, said invention consists of the means hereinafter fully described and particularly pointed out in the claims. I

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings: Figure 1 shows in outline an unloading tower for handling railway cars in connection with a loading apparatus of the kind in hand, the relation of the latter to the vessel to be loaded being thus shown; Fig. 2 is a front elevation on a larger scale of the discharge chute of such apparatus, in which chute has been incorporated our several improvements; Fig. 3 is a side elevation of the same; and Fig. 4 is a view showing the construction of one of the details entering into the aforesaid chute.

Referring, first of all, to Fig. 1, the un loading tower A which in itself forms no part of the present invention, will be seen to be disposed at the edge of the dock A, alongside of which the Vessel A to be loaded is moored. Such tower is provided with an inclined pan or apron B terminating in a straight chute C that conducts the material into the hatchway of the boat, such chute being su ported so as to be oscillatory in a vertical plhne transversely of the vessels hold. Suitable means that do not here require to be described in detail, are adapted to elevate railway cars and tilt the same so as to discharge their contents .into the pan, while other means are adapted to adjust the position of the pan and of the chute vertically so as to deposit the material being unloaded at any desired point in the plane of the latters oscillation. Thence flowing laterally such material will more or less completely fill up the hold. Owing, however, to the fact that the hatchways do not provide a continuous opening in the vessel deck it is obvious there will be s aces left between such hatchways unless the material is scattered laterally by other means than those thus far described. As it is with means for automatically effecting this result that our resent invention is concerned, the description of such means will now be more fully taken up.

The oscillatory chute C, whereby the material is conducted from the pan to the vessel hold, has the walls of its discharge end 0 c on the sides transversely disposed to such plane of oscillation prolonged, Figs. 2 and 3. In

such prolonged wall portions provided two two sets of curved slots 0 c which act as guides, and respectively incline toward 0 osite sides of the chute, terminating in tile ower corners of such prolonged portions. At the points where they would intersect the walls, openings 0 c are provided, and a continuation c c of the guides c 0 carried on the inner faces of plates 0 c projecting laterally of the chute for practically the remainder of its length. Slidably mounted in such sets of guides, respectively, are flexible deflecting plates, 0 C, that in their raised positions are adapted to be supported exteriorly of the chute in the upper portions 0 0 of the guide-ways referred to, but in their lower positions are adapted to lie diagonally of the lower discharge end being held in the curved portions 0 c of the guide-ways formed in the prolonged wall portions. These deflecting plates may be variously constructed, but, as shown, are formed of bars 0 (specifically T-bars) disposed so as to present their flat faces towards the inside of the chute and their ribbed faces toward the out side thereof, the ribs thus serving to reinforce the sheet. These bars are ivotally connected together by means of iinges Fig. 4, attached to such rear sides by rivets 0 and the T-ribs are cut back a short distance from either side of the sheet to permit the latter to slidably engage the slots 0 c. To raise and maintain the respective deflecting plates thus constructed in their upper positions a Windlass consisting specifically of a drum C and a cable 0 connected therewith and passing over a pulley c, is provided for each plate. The weight of the plate it will be understood is adapted to cause the same to descend upon release of the drum of the Windlass, which is normally held against rotation by a pawl 0 ratchet c, or equivalent means. Rotation of either drum to wind up the cable and raise the corresponding plate C is efiected by means of a crank c in the usual way.

The operation of our load trimmer should be fairly obvious from the preceding description of the construction of its component parts. Normally both deflecting plates will be held in their raised positions leaving the lower end of the chute perfectly free and open. In this condition the material is discharged directly into the hold in theregular manner and this condition will moreover ob tain during most of the loading operation. It will be observed that when the chute is thus employed the slots constituting guides 0 offer no impediment to the passage of the material through the chute. When, however, that portion of the hold beneath any particular hatchway is nearly full and it is desired to fill the covered space between such hatchway and the one next adjoining, one or the other of the deflecting plates is lowered into its operative position. The stream of coal descending the chute is thereupon diverted from its straight path to one side or the other, depending upon which plate is thus lowered. By giving a proper curvature to the guides wherein the deflecting plates are held, it will be obvious that such deflection can be effected without subjecting the coal to severe pounding such as would be apt to break the lumps and produce an undue amount of slack, which is objectionable.

It is of course understood that our trimming device while .described as specifically adapted to the loading of coal, will be equally effective in the handling of any other material, particularly any material of like heavy nature, in the handling of which a flexible spout, such as is used in loading grain or the like, cannot be employed for the reason that such spout would be knocked to pieces by the impact of'the material descending the chute. It will be equally obvious that the device is susceptible of equally advantageous use in other connections than in the hauling of vessels, for the trimming of a load is an essential incident to the proper loading of cars and the filling of bins as well.

Other modes of applying the principle of our invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any one of the following claims or the equivalent of such stated means be employed.
