IMPROVEMENT IN SLINGS vFOR LOADING AND UNLOADING HAV, &c.
Specification forming part of Letters Patent .No. 142,633, dated September 9, 1873 application filed June 21, 1873.
" To all whom it may concern:
Beit known that I, GEORGE W. LONG, of Delaware Centre, in the county of Delaware and State of Iowa, have invented a new and Improved Apparatus for Loading and 4Unloading Hay, 85e., of which the following is a specification In the accompanying drawing, Figure l represents a top view, partly in section, of my improved apparatus for loading and unloading hay, 86o.; and Fig. 2, a side view of the double hook to which the ropes are hitched.
Similar letters of reference indicate corresponding parts.
The object of my invention is to provide efficient means for the rapid unloading of hay, corn-fodder, sugar-cane, manure, and other y farm products, by which the whole load is packed and hoisted up directly from the Wagon and conveyed and stored at the place of destination. My invention consists-of two strong pieces of Wood, which may be connected and disconnected by means of leverhooks and string attachment, to which the load is attached by knotted ropes, in connection with a double hook for hoisting. After conveying and hoisting the load to the point desired, it is detached by disconncctions Of the main pieces.
In the drawing, A A' represent the main connecting-pieces ofthe apparatus, of wood, and suitable dimensions. Piece A is provided with a central perforation for guide-pin a of piece A', and two longitudinal side recesses, b, with cross-pins d. Eyes or staples e have strong ropes f applied to them, which are providedv with knots g, at suitable distances. Piece A' has pivoted into correspond ing recesses b', at d', the lever-hooks B, which lock with their hook ends over the cross pins d of piece A, connecting together with pin a the pieces A A'. rlhe lever ends of hooks B project` beyond piece A', and pass-through perforations ofthe sliding bar C, which is furthermore provided with slots h for the eyes or staplese', having similar knotted ropes, f', as piece A. At 4the end `of sliding bar Gis attachedl the trip-rope D, which passes over a small pulley, i, near end of piece A', and through a hole of band Or bar E, to which the pulleyshaft is secured, and which also protects rope D, so as to produce the ready action of the saine on sliding bar C and the ends of hooks B. The lever ends of hooks B are, by the pulling of the trip-rope D, carried B from pins d and disconnect pieces A A'.
`A spiral spring, l, applied to a lug, m', of sliding bar C in recessn of piece A', acts in Oppositedirection to that Of trip-rope D, securing the closing of yhooks C to piece A till the strain on rope D overcomes the resistance of the spring Z. To the end 'of piece A is attached the guiderope F,'by which the sling is controlled and drawn back to the Wagon after the same is unloaded.
For loading and unloading manure, chaii', and other short articles, intermediate ropes., which pass crosswise from the pieces A A' to the ropes ff', together with light slats connected parallel to the pieces A A', are used, as indicated byA dotted lines in Fig. l.
For using the apparatus or sling, one Or more of them, as desired, are placed on the rack, with pieces A A' On and in the longitudinal direction of the same. The ropes f f' are hung sidewise over the rack. The load is then placed on and divided equally over the slings, if more than One are used. The ropes f f are then brought around the load, and the knots g g' hitched into double hook G, Fig. 2, from both sides, so that a firm and strong binding of the load is produced. The wagon is then driven to the place Of unloading, and central hook o of double hook G placed into the ring of the hoisting-rope, lifting the load contained in the sling directly from thj'e wagon by means of suitable pulleys and power, and guiding it by rope F. When, arrived above the place of storing, the trip-rope E is pulled, the pieces A A' separate and drop the load instantly to the place required. When one sling only for the full load is used, the whole may be unloaded at once by the use of a capstan, in which the lever throws out of gear and allows the sling to be drawn down without backing the horse. 4
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The bar A, provided with recess b and cros`spins d, in combination with the bar A', piv- Oted 4hooks B, sliding bar C, spring n, trip.- rope D, andropes f and j", as and for the pur- GEORGE w. LONG.
lpose specified.
