WILLIAM T. SCOTT, OF PARKERSBURG, IOW'A.

LOADING APPARATUS.

Application-filed June '11, 1909.

To all whom it may concern:

Be it known that- I, lVlLLIAM T. Soon, a citizen of the United States, residing at Parkersburg, in the county of Butler and State of Iowa, have invented certain new and useful Improvements in Loadin Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in loading apparatus.

()ne object of the invention is to provide an apparatus of this character by means of which manure, hay, sand, and other material may be elevated and lowered into or out of a wagon.

Another object is to provide an improved construction of grappling fork, having an improved tripping and load releasing mechanism, and having means whereby the aws of the same may be quickly converted into scoops to enable the fork to lift sand, dirt, and similar material.

With the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be more fully described and particularly pointed out in the appended claim.

in the accompanying drawings: Figure 1, is a perspective view of loading apparatus constructed in accordance with the invention. Fig. 2, is a top plan view of the grappling fork, showing the jaws in closed position. Fig. 3, is a cross sectional view of the same on the line 33, of Fig. 2. Fig. 1, is a similar view showing the jaws in open position; and, Fig. 5, is a perspective View of the fork, showing the jaws in open position and equipped with scoop plates, and Fig. 6 is a detail fragmentary sectional view showing a portion of one of the teeth of the grappling fork and one of the scoop plates in section.

Referring more particularly to the drawings, 1., denotes the base plate of the apparatus, and 2, denotes the mast, the lower end of which is revolubly mounted in a step bearing formed in said base plate, whereby sait. mast may be freely turned to swing the load to the desired position. The mast is held in position by inclined brace bars 3, the lower ends of which are secured to the base plate 1, and the upper ends to a supporting Specification of Letters Patent.

ring t, which is arranged on and loosely engages the mast 2, adjacent to its upper end, as shown. The mast may also be further supported by a guy rope 5, the end of which has a swiveled connection with the upper end of the mast. The upper end of the mast recessed. or slotted and in said slotted end is revolubly mounted a guide pulley 6.

Slidably mounted on the mast 2, is a boom 7, said boom being preferably loosely connected at its inner end with the mast by a suitable clip 8. In the outer end of the boom are arranged two guide pulleys 9, between which and engaging the guide pulley 6, in the upper end of the mast is a hoisting rope or cable 10, said rope extending down from the pulley 6, along side the mast and through a guide pulley 11, secured thereto adjacent to its lower end. From the pulley 11, the hoisting rope is passed once or twice around a drum or pulley 12, which is mounted in suitable bearings 13, arranged on the base plate 1, and from the pulley or drum 12, the rope extends a suitable dis tance from the hoisting apparatus and is connected to a suitable draft device, by means of which draft animals are hitched thereto to raise the load connected to the opposite end of the hoisting rope or cable. Connected to the boom, near its inner end, is a raising rope or cable 14, and to the boom adjacent to its outer end is connected a similar rope or cable 15. The cables It and '15, pass over a guide pulley 16, secured to the mast and from thence extend downwardly and are adapted to be secured to a cleat 16, arranged on the mast adjacent to its lower end. By means of the rope or cable 1 1, the boom may be raised bodily on the mast to any desired elevation, while by means of the rope or cable 15, the outer end of the boom may be swung upwardly to any desired angle. To the boom 7, is also connected a cord 17 by means of which the boom may be swung around to any desired position.

Connected to the end of the hoisting rope, is a grappling fork 18, said fork comprising a pair of jaws, each of which consists of a bar 19, which is preferably formed of metal and to the outer side of said bars are secured a series of curved teeth or tines 20, said tines being secured to the bars 19, by bolts 21, and clips 22. On the inner side of the bars 19, are arranged a series of bearing eyes 23, through which is inserted a pivot bolt or rod 24:, the ends of which are bent at right-angles or headed to prevent the dis engagement of the bolt or rod from the eye.

In the inner sides of the bars 19, adjacent to their lower edges are formed recesses in which are arranged eyes 25, to which are secured jaw closing and supporting cables 26, said cables being connected at their upper ends to a hoisting ring 27, with which is adapted to be engaged a hoisting hook 28, which is secured to the end of the hoisting cable, as shown.

To the outer side of the bars 19, adjacent to their lower edges are secured supporting and opening cables 29, said cables being connected at their upper end to the lower end of the hoisting cable, as shown. The opening and supporting cables 29, are of greater length than the combined length of the hook 28, and the closing and supporting cables 26, so that when said hook is engaged with the ring 27, the fork is supported by the cables 26. The connection of the lower ends of the cables 26, with the bars 19, of the fork, is such as when the hook 28 is engaged with the ring 27, the jaws of the fork will be drawn inwardly or together, thus grappling and securely holding the load between the same.

When the jaws have been engaged with the load and the hook 2S, engaged with the ring 27, the hoisting cable is operated to draw the fork upwardly to the desired elevation and the boom is then swung around to the desired position. IVhen the loaded fork has thus been brought to the proper position, the hook 28, is disengaged from the ring 27, by a trip rope 30, which is connected to the hook 2S and passes through a guide eye 31, arranged in the boom. \Vhen the hook has thus been disengaged from the ring, the weight of the loaded fork will be thrown on the opening and supporting cables 29, which, owing to their manner of connection with the aws, will swing the latter upwardly to an open position, thus dumping the load.

In connection with the tines or teeth of secured in any suitable manner.

the jaws of the fork, I provide scoop plates 32, which are preferably formed of sheet metal and are curved to fit the curvature of the teeth 20, to which they are detachably On the lower edges of the scoop plates are arranged V-shaped steel scraping blades 38, which engage and fit over the ends of the teeth or tines, thus facilitating the use of the fork for lifting or hoisting sand, dirt, or fine manure.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention, as defined in the appended claim.

Having thus described my invention, what I claim is:

In combination, a grapple comprising a pair of pivotally connected bars, outwardly curved teeth secured to said bars, jaw supporting and closing cables connected with the inner and lower edges of said bars, a supporting ring for engaging the free ends of said cables, a hoisting cable a connecting hook connected with said hoisting cable and adapted to engage said link to normally hold the jaws closed, opening cables connected with the outer faces of the bars of the grapple and with the hoisting cable, said opening cables adapted to support the weight of the grapple when the hook is disconnect ed from said link, and releasing means for said hook.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
