These plates inafter fully described and claimed. are arranged on opposite sides of the bars A In the accompanying drawings, forming a and B and are held in position by means of a part of this specification, and in which like bolt c, passing through the bar A, and a bolt 8o 3o letters of reference indicate corresponding 02, passing through the plates above or to parts, we have illustrated an embodiment of one side of the bar A, as clearly' shown in our invention, although other forms of em Fig. 4t. Instead of making these plates of bodiment thereof may be employed without two pieces of metal they may be each condeparting from the spirit of the same, and in structed of a single piece of metal bent to the 85 3 5 these drawingsappropriate shape. The portion of the plates Figure l is a view in side elevation with through which the bolt c2 passes is bent inthe parts locked. Fig. 2 is a similar view ward to form two shoulders c3, which are dewith the parts unlocked. Fig. 3 is atop plan signed to prevent lifting of the bar B when view.

Referring to the drawings, A designates a The hooks or pawls D are each provided supporting bar or plate of metal, and prefwith a lug or extension CZ, designed to engage erably rectangularin cross-section B, a tripa recess h5 in the edge of the bar thatvwill be bar arranged parallel with the supportingthe under one in use and with a hook d2 to 95 45 bar; O, a series of connected plates; D, a engage the boltc, as shown in Fig. 1. The series of chain-carrying hooks or pawls adapthook has a rope or chain G connected with it, ed toengage with a fixed part of the bar A to constituting the sling or binder to be fas` support the load, andEa lever for operating tened around a bundle of sugar-cane or the `the trip-bar. like, any suitable means, as a hook, being 10o 5o The trip-bar B works in a 'plane parallel employed to secure the end of the binder in with the supporting-bar A, and at one end is place. The bolts c2 are engaged by ropes or Vrecesses b5, as shown in Fig. 2,

chains H, by which the apparatus may be suspended in position from a suitable overhead support.

In operation the hooks D are brought into engagement with the bolts c, with the lugs d resting in the recesses b5 of the bar B, the spring F operating to hold these parts assembled. The apparatus is then placed on the bottom of a cart or wagon with the slings G laid out straight, and cane or the like in sufficient quantity is loaded onto the slings, after which these slings are secured in place around the bundle. The wagon or cart is then brought to an unloading station, and the bundle is lifted out of the vehicle and suspended by the chains H. lVhen the bundle thus suspended is to be released from the slings, the lever E is drawn back, thereby moving the bar B forward and releasing the hooks from engagement with the bolts c and and causing the bundle to drop.

The mechanism for lifting the bundle from the cart or wagon may be an ordinary derrick or a form of loading and unloading device, such as that constituting the subjectmatter of an application iiled by us in the United States Patent Ofice August 23, 1805, Serial No. 560,244.

Having thus fully described our invention, what we claim as new, and desire to secureby Letters Patent, :is-

1. A sling-trip comprising a supporting bar, a trip-bar arranged in parallel relation with the supporting-bar and having recesses in one of its edges, and sling-carrying hooks or pawls adapted to engage a fixed part of the supporting-bar and the recesses of the trip-bar, and to be released by the trip-bar, substantially as described.

2. A sling-trip comprising a supportingbar, plates secured thereto, a trip-bar working between the plates, and sling-carrying hooks or pawls adapted to engage a fixed part of the supportingbar and to be released by the trip-bar, substantially as described.

In testimony whereof we afiix our signatures in presence of two witnesses.
