SHOCK-LOADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 405,840, dated June 2 5, 1889.

Application filed February 4, 1889. Serial No. 298,662. (No model.)

To all whom it may concern.-

l Be it known that I, WILLIAM J. JAcoBs, a citizen of the United States, residing at Bargersville, in the county of Johnson and State of Indiana, have invented a new and useful Improvement in Shock-Loading Machines, of which the following is a specification.

My invention relates to an improvement in that class of machines for loading shocks of hay, corn-fodder, or like crops, upon a wagonbed, which consists of a lever mounted upon a vertical standard, so as to swing vertically and horizontally thereon, said vertical standard being erected on the wagon-bed.

The objects of my improvement are, first, to provide great lifting-power; second, t0 provide improved means for engaging and disengaging the shock, and, third, to provide means for easily dismounting the vertical standard and the parts carried thereon, all as hereinafter fully described.

Figure l represents a plan of the loading device in position on the wagon-bed or hayrack; Fig. 3, a side elevation of the same; Fig. 3, a partial elevation, showing on a larger scale the Inechanism for engaging and disengaging the shock. Fig. 4 is a perspective view of the base and the mast separated.

The base of the loader consists of two beams A and B, framed together to form a Tshaped frame, and a tubular sleeve C, supported above the point of intersection of beamsA and B by braces d d and e. This base is permanently secured to the wagon-bed D by bolts passing' through the frame, or in any other suitable manner.

F is a short cylindrical mast adapted to tit into sleeve C so as to turn easily therein. The lower end of the mast is provided with a pin h, which enters a corresponding hole /L' in the base. A lever J is pivoted at one end by a pin k to the mast, above and near the sleeve C. A second lever K is hinged to a fulcrum f, which enters a socket in the top of the mast, and its shorter arm is connected with lever J by a chain l. A compound lever is thus formed, which swings in a vertical plane on the mast and swings in a horizontal plane by turning the mast in sleeve C. The free P is a flat metallic bar having at one end L* an eye q to receive the rope n, and having the other end bent to one side and provided with a stud o'.

S is a thin flat disk having a central hole, and having in its edge a deep notch t and a smaller notch u, the arrangement being such that when the disk is mounted on stud r, so

as to turn loosely thereon, and notch t is,

turned upward, bar P and stud r will stand between the notches. The disk is temporarily held in the above-described position by means of a pawl c, pivoted to bar P, and ar ranged to engage notch 'a in the disk. A light cord w is attached to pawl fn and is passed through an eye a; on the lever K, and thence along levers K and J within convenient reach of the operator.

The operation of my device is as follows: The wagon-bed or hay-rack carrying the device having been placed near the shock to be loaded, the free end of lever K is swung outward and depressed until the trip-hook, depending therefrom, is within reach of an attendant. The attendant places the binder of the shock in notch tof disk S- and engages notch a with pawl c. The operator then, pulling downward on rope m, raises the free end of lever K and the shock, at the same time turning the mast by means of lever J, and thus swinging the shock over the wagon-bed. When the shock has been brought into position, the operator pulls cord w and thereby discharges pawl e from notch u in disk S. The weight of the shock now causesdisk S to turn on stud o' until the binder of the shock slips out of notch z., thus discharging the shock upon the wagon-bed. After the load has been obtained, or when the wagon is required for other purposes,the mast and the parts mounted IOO thereon may be quickly removed by liftingthe having notches t and u, the paWl pivoted to ro mast out of sleeve C. AThe base then takes the bar and arranged to engage one of said up but little space andrneed not bereinoved. notches, and the trip-oord attached to Said I claim as my inventionpawl, al1 arranged to co-operate substantially 5 In a shock-loading machine, the oombinaas and for the purpose speeiied.

tion, With the mast and the lifting-levers WILLIAM J. JACOBS. mounted thereon, of the trip-hook consisting Witnesses: of the bar suspended from the free end of the JOHN W. J ONES,

lifting-level", the disk pivoted to the bar and I-I. P. I'IOOD.
