' SKiP FORjI-IAULING coAL'ANn OTHER CARGO.

new and useful Improvements in Skips for Hauling Coal and other Cargo, of which the following is a specification.

This invention relates to skips for haul-' ing coal and other cargo out of or into ships, and provides a skip capable of being filled and emptied in either of two directions in an expeditious manner. The improved skip is specially adapted for use in the holds of ships, more particularly when cargo has to be hauled from a distance below decks to a hatch. The skip can also be readily loaded and unloaded by one man in the ship and another man on the wharf or in a railway truck or other vehicle.

The body of the skip has sloping ends and athwart its middle part is provided with a stiffener having an upper bar.

A bow pivoted to the sides of the skip below the center thereof is provided with a spreader bar just above the skip body, and

also has a. link or housing formed on itsupper portion.

Levers pivoted on the spreader bar of the bow have projections at their outer ends,

which pass through said bar and engage slots in the upper bar of the stiffener.

The inner ends of the levers are formed with slots which engage pins on a cross head, from which a stalk passes upward and has atv its upper end a loop working freely in the link or housing of the bow.

When hoisting the skip the hook of the lifting gear is entered in the loop of the stalk, with the result that when the lifting strain is put on, the stalkis drawn upward in the link or housing of the bow, and causes the levers to lock the bow to the skip body.

When the lifting strain ceases, the stalk drops, and the levers are disengaged from the cross bar of the skip, whereupon the bow can be swung either way, on the latter.

In a modification, the bar isformed with an eye above the housing in which the loop of the stalk works, and when lifting, a rope is attached to the eye and another rope to the loop of the stalk. While strain is on both ropes, the skip body is locked to the bow, but immediately the rope attaehed to the loop of the stalk is slacke'ned off the of a locking lever and the bar carrying speflificatiofi 0f rs vPatent PatentedJune 1, 1 920.

levers are disengaged from'the cross bar of the skip body' and the latter is unlocked from the bow, whereupon the skipcan be tipped. V V

Referring to the accompanying drawing in conjunction with which the invention will be more particularly described Figure l is a cross sectional View, and Fig. 2 'a longitudinal sectional view of the improved skip. 9

Fig. 3. illustrates an alternative construc- 'tion employed at the top of the bow.

Fig. 4' illustrates in perspective, portion same.

The skip body is formed with sloping ends 1, and has sides 2 the upper edges 3 of which incline downward from the center to' the ends 1. I

A stiffener 4 having an upper bar 5 is secured across the skip between the sides 2, midway of theends 1, for the purpose of strengthening the body, the bar 5 having slots 6 formed therein one near each end.

The bow 7 is pivoted to the sides 2' below the center thereof and midway between the ends 1, said bow 7 being provided-with a spreader bar 8 capable of clearing the bar 5 so as to allow the how 7 to be m'oved to either side. on the spreader bar 8 are pivoted levers 9 which terminate at their outer ends in projections 10 the latter passing through slots 8 in the spreader bar 8 and engaging the slots 6 of'the bar 5, when required.

The inner ends of the levers 9 are formed with slots 11, said slots being engaged by In usethe hook of a lifting rope is made 100 to engage the loop 17 of the stalk l i,'and immediately a strain is put on said rope',the loop 17 is drawn upward 'in the link or housing 16. This causes the projections10' of the levers 9 to enter the slots 6 in the bar 105 5 of the stiffener 4, and so look the how 7 to the body of the skip. V p r The skip is then lifted and deposited where required, and immediately the'lifting strain ceases, the stalk; 14 drops down 110 and causes the projections 10 of the levers 9 to moveupward out of the slots 6 of the bar 5.

The bow7 is thenfreeto swing on itspiv ots to either side until its rests on the edges 3 of the sides 2. p

When discharging a loaded skip into (say for instance a railway truck) the skip is al-' lowed to rest on the truck until the projec- V hoisting rope, the skip is tipped and its contents discharged.

the modification shown in Fig. 3, an

eye IS is provided above the link or housing 16, and in practice a rope is attached to the the loop 17.

Both ropes take the lift, and to discharge the skip the rope attached to the'loop' 17 is slackened off. This permits the levers 9 to unlock the skip body from the bow 7 whereupon said body can be tipped in the how 7 while suspended.

When hauling cargo at a distance below decks to a hatch the skip body is unlocked from the bow and tipped, and being hauled while in the latter position acts as a scoop to pick up coal or other cargo.

The body of the skip can be of a size and shape to suit circumstances, and in some cases a truck can have a bow and central cross bar fittedthereto as before described in order that cargoes can be loaded direct into or from a truck and the latter deposited where required. lVhat I do claim and desire to secure by Letters Patent of the United States is 1. A cargo skip having a body fitted. with a slotted central cross bar; a bow pivotally connected to said body and containing a slotted spreader bar; a stalk with a looped upper end working in a housing at the top of thebow; and locking members connected to said stalk and operated by the latter to pass through the spreader bar and engage the cross bar of the body.

2. A-cargo skip, having, a body fittedwith a slotted central cross bar; abow pivotally connected tosaid body and containing a i to the rope attached to 1 V a central cross bar slotted near each end; a

a bow pivotally connected to the sides of the gage the slots of the cross bar of thebody; a cross head with pins projecting therefrom connecting the slotted ends of said levers;

and a stalk connecting said cross head with a loopworklng in a housing at the top of the bow. v I g a v 4;; A cargo skip, having a body fittedwith body below the center thereof andcontaining a spreader bar slotted near each end;

levers with projections at their outer ends and slotted at their inner ends pivoted on .said spreader bar, so that the projections can pass through'the slots of the latter and engage in the slots of the cross bar of the bodyja cross head with pins projectingtherefrom c onnecting'the slotted ends of said levers; and a stalk connecting said cross head with a loop working in a housing at the top of the bow. i

5. In a cargo skip, a bow pivotally conbar; a'housing at the top of said bow; members passing through said spreader. bar; and a stalk connecting said members with a loop in said housing.

nected thereto and containing a spreader 6. In a cargo skip, a bow pivotally connected thereto and containing a spreader bar; a housing and an eye at the top of said bow ;v levers pivoted to saidspreader bar; and a stalk connecting said levers, with; a loop in said housing. M
