To all, whom it may canoes-n;

Beit known that I, VVALLAOE L. NEWELL,

a citizen of the United States, andgresident of the city 01:" Seattle, county of King, State of -Washington, have invented certain new and useful Improvements in Cargo Han. dling Devices, of. which ,the followingis a specification.

My invention relatestoa, machine or apparatus, for handling cargo between vessels; and docks, and particularly .cargo of. the. sort which islmown as. package freight,that.v

is articles which" are put up in packages, and wlnchare generally, handled upon trucks,

The object of myj invention is to produce.

a typeof apparatus which may. be used to hoist cargo out -1 of a vessel, and place it .upon the trucking floor of thawarehouse, and conversely to transfer such cargofrom the ware; house to the hold of a vessel.

My invention comprisesrthe various elements and icombinations thereof, which will be hereinafter described, andthen particur larly pointed .out in .tl1e claims.

In the accompanying drawings I have shown. my, invention in a simpletypev of construction, the same being illustrative of :the principles of; my invention, and the preferred manner of carrying out tl e sarne. I

Figurelis, a side elevation ,otmy device,

showing it in its relationto both thewares justin-gthe same to compensate for varying.

distances to the elevator.

Fig. 6 is,asectionshowingonetype of construction of the telescopic or adjustable elevator guideways.

Fig. 7 is a detail, showing the mannerof vertically adjusting the tower and the boom. In the drawings 9 representsa warehouse which is set back a suliicient distance from the edgeof the dock to provide space for the tower of my device, and .90 representsa vessel which is lying alongsideof the dock.

The tower 1 is mounted-upon wheels lO, which travel upon rails carried bythe dock, southatthe device as a whole may betrayersed'along the edge of the dock.

A boom 2, preferably oftruss construction, ishinged to the towerfat 11, to swing secured by other means.

in a vertical plane. The swingingof the boommay be done. by any...suitable means. As. herein shown the boom is supported and controlled in. its, swinging movements means of hosting cableslQ, which passover pulleys .13, mounted respectively at the outer 611Cl10f,tl16 boom, andat the upper end ot theltowerh This hoisting cableis controlled es from, the. power plant, which is located at lttinthe basenot-the tower. When not in. use, the, boom is intended ;to;.be swung 1111- ward .to such a position as not to obstruct themovement of a vessel alongside the dock.

Theboom ,2 has a trucking floor thereon, the Same being preferably provided with an adjustable, se'ctionqorv sections, which may be moved or adjusted soas to be out of the. wayofs-thei elevator guideways whenthe boomis'raised, and-also so astoacoommo-y. datethe position of the elevator. guideways lengthwise of the boo1n. Suclradjustment may be by the means'shown in Figs. 4 and l 5, in which 3 represents a section of the floon so which may be afixedsection, and 30 repre sents asection which is. adjustable lengthwiseof the boom, and is supported at an elevation just above the section 3, whereby. it may be moved lengthwise the boon as mayfg5 be desired. 7 V The adjustablesectioir 30 is preferably provided withfan inclinededge 31,150, that; trucks, may pass from one section to the other withoutmeeting too serious an obstruction. .90 These adjustable, sections may be. made in number, whatever is required to meet. the] necessities of the particular. case. The ads justability of thefloor sectionsmay also be The elevator guideways which in general. are represented in Fig. lby the figurel, of an. extensible or. collapsible construction as by being made telescopic in character, so that after beingplacedin positionover the hatchways, the telescopic parts thereofmay ,belowered .into. the hold of the vessel. Varione means for raising and lowering these sections may be employed. I have notherein illustratedany definite means for doing this 10s as suitablemeans for doing this would be evident. The. telescopic character of these guideways maybe securedzby. the type of constructionshown in Fig. 6. In this constructionthe bars 40 and their connected parts, being the outermost ends of the series, areconnected together and form'the upper-- mostsection, which section may or may not fbe adjustable vertically uponthe boom. The t bars ll and their connected parts form the next section, and the bar 42 at the center of the series, forms the lowermost section.

These may be, hoisted and lowered to remove the guideways from the hatchways, or to lowerthem therein. Anyother suitable type of construction than that shown, may be used as'a substitute therefor. v

The elevator guideways are preferably mounted so that they may be adjusted lengthwise of the boom. This may be securedby various means. As herein shown, I employ a car 5, which 1s mounted upon a trackway' '50 carried by the boom, thus permitting a limited movement of the car lengthwise the boom. To prevent overably'carried upon the car 5 by means of a hinge or pivot 53. In raising and lowering the boom,.the elevator guideways may' thus be permitted to swing, whereby'they' will at all times maintain a vertical position. 'Such position is indicated by the broken line'position shown in Fig. 1. The position of the helevator guideways when lowered, is shown by full lines inFig. 1. In the same figure by dotted lines at 43, is shown the positions of the varioussections of the elevator guideways-raised, or telescoped together. The number of telescopic sections may be varied to suit the conditions. The various sections "of the elevator guideways are preferably provided-with means whereby theymay be steadied from the hatchways' and vessel, as forinstanceby means of bars 45, which are adapted to engage the hatchway combings.

' i Mounted upon the elevator guideways are platform elevators, preferably two in number, counterbalanced so that one is going up when the other is going down. In F 1g. 3

one of these is shown at the top, and the 'other at the bottom, these being connected by ropes 60 which pass over pulleys, carried at the upper end thereof. These cables preferably are conducted over suitable pulleys tot-he power plant 14 and thence back.

The control position from which the operator handles the elevators, is preferably located at the outer end of the boom, as for instance at the point 20, as in this position he is able to'see down the hatchways, and

see all along the boom in the warehouse.

'I have herem'shown the tower as composed of a base section 15, and an upper or main section 16, the latter being the section to which the boom is secured, and which also" carries the power plant. These two sectlons may be made'vertically adjustable, whereby the boom may be adjusted to accommodate to delivery floors at somewhat different elevations.

The manner of raising and lowermg the upper sect1on'16 ofv the tower, may vary.

, The means herein shown consists of threaded bars 17, which are connected by means of horizontal shafts 18 and bevel gears 19, so that all of them may be operated alike and simultaneously.

In operating my device the tower is moved along its trackway upon the dock to the point where it registers with the opening in the warehouse, through which the freight isto pass, and also into registry with the hatchway of the vessel. The boom 2 is then lowered until it is over the hatchway. If necessary the car 5 carrying the elevator guideways is moved along the boom until the guideways are directly over the hatchway. The guideway sections are then lowered until the lowermost reaches the lowermost deck, from which it is desired to take, or to which it is desired to deliver freight. The elevator controlling cables are then adjusted in length to reach the desired decks.

T he device is then operated by placing the freight upon the elevators and hoisting or lowering the same, as may be necessary to remove the cargo from the vessel, or to place it inthe vessel.

The cargo is preferably handled by means of trucks, which may be lowered within the hold of the vessel when cargo is being moved from the vessel, then rolled upon the elevator platfornisand hoisted to the trucking floor of the boom, at which point they are run off of the elevator platforms and transferred to the warehouse.

WVhen freight is to be placed from the warehouse into the vessel, the order of procedure is reversech'the trucks being loaded in the warehouse, run out upon the boom and aboard the platform of an elevator, loaded into the vessel, and then removed to the point in the hold where the freight is being stored.

When in use, the space between the floor of the boom and the floor of the warehouse is bridged by a short section of flooring, or suitable gang-way 21.
