WAGON-BED HOIST.

To all whom it may concern Be it known that I, ALVIN L. Cox, a citizen of the United States, residing at Elizabethtown, in the county of Hardin and State of Kentucky, have invented certain new and useful Improvements in lVagon-Bed Hoists, of which the following is a specification.

My invention relates to hoisting. means for wagon bodies, to remove the same from the wheeled frame of the wagon, and has particular reference to means of the above mentioned character including a Windlass or winding mechanism and means whereby such Windlass or winding mechanism may be detachably connected with the. wagon body when the same is'being elevated. and disconnected therefrom after the wagon body has been raised to the desired position and suspended or otherwise supported in such raised or elevated position.

An important object of this invention is to provide means of the above mentioned character, whereby a single Windlass or winding means may be employed to elevate any-number of wagonibodies, when the same are provided with the necessary elements, to cooperate with the Windlass or winding mecha nism.

A further object of this invention is to provide means of the above mentioned character, which are simple in construction, cheap to manufacture, strong and durable.

A further object of the invention is to provide means of the above mentioned character which may be used in connection with different types of wagon bodies without materially altering their construction.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure l is a side view of the hoisting means, showing the same applied to a wagon body, Fig. 2 is a plan view of the same, and, Fig. 3 is an end view of the same.

In the drawings, wherein is illustrated a preferred embodiment of my invention, the numeral 4 designates a wagon body, of any well known or preferred type. body is preferably provided at its ends with transverse beams 5 and 6, rigidly attached thereto.

The numeral 7 designates a wlndlass as a Specification of Letters Patent;

whole, comprising a rotatable shaft 8, provided at its outer end with a spool or drum 9, having ends or heads 10 and 11, as shown. At its inner end, the shaft 8 is provided with an enlarged head 12. The end beam 6 is provided with a U-shaped 2 depending bracket or bearing 12, as shown.

Rigidly connected with the bottom of the wagon body 4 near and spaced from the end beam 6 is'a transverse beam 18, which is thinner than the end beam 6, as shown. This transverse beam 13 carries a depending U-shaped bracket or bearing 14, rigidly attached thereto. Attention is called to the fact that the bracketor bearing 14 is disposed in a horizontal plane above the bracket or bearing 12, asshown.

. The brackets or bearings 12 and 1 1 are constructed sufficiently large to allow of the passage therethrough of, the shaft, 8, and the head 12 carried thereby. When theshaft 8 is being inserted within the braoketsor bearings'12 and 14, said shaft is slightly inclined, as shown by the dotted lines. The shaft. 8 assumes this position when being removed. When the .windlass is being. operated to elevate, the wagon body, an upward pull being then exerted upon the outer end thereof, the rotatable shaft 8 as sumes a suitable horizontal position, the

outer portionjof the same; engaging the proper displacement or removal ofthe windlass.

The head or end 11 is provided with an extension 15, disposed within an opening 16 formed through the lower end of a locking lever 17, these parts being pivotally connected by a transverse bolt 18. The locking lever 17 is provided at itsfree end with a head or catch 19, for a purpose to be described. The lever 17 is also provided at its outer end with a laterally extending handle or crank 19, as shown. The head 11 is also provided with a radially inclined opening or notch 20, for a purpose to be described.

The numeral 21 designates suitably supported stationary or fixed supports or beams, carrying pulleys 22. These pulleys are engaged by a flexible element 23, which may be a cable, chain, rope or the like. The

flexible element 23 has one end thereof provided with a loop 24, to be passed about the transverse beam 5 and the forward end of the wagon body 4;. The opposite end of the flexible element 23 is provided with an enlargement or head 25, which may be formed by tying the rope in a knot or by other means. This end of the flexible element 23 is adapted to be inserted within the opening 20, the head 25 preventing the rope from accidentally moving out ofthe same. When the Windlass 7 is rotated the flexible element 23 is wound upon the drum or spool 9, as is obvious.

Connected with the end of the flexible element 23 adjacent the Windlass is a ring or link 26, adapted to receive ahook 27 attached to a loop 28,- which is formed of a flexible element such as a rope, cable or chain. The detachable loop 28 receives the rear end of the wagon and the end beam 6.

The operation of the apparatus is as follows: The flexible element 23 preferably remains suspended from the pulleys 22. The loop 24 is first passed about the forward end of the wagon body and the end beam 5. The loop 28 is then passed about the rear end of the wagon body 4 and the end beam 6. The shaft 8 of the Windlass is now passed through the bearings-or brackets 12 and 14, subsequently to which the free end of the flexible element is inserted within the opening 20. The lever 17 is employed to rotate the Windlass 7, the operator turning the lever 17 by means of the crank 19, to wind the flexible element 23 upon the drum 9, whereby the wagon body 4 is elevated. When the Wagon body has "been sufficiently elevated, the hook-27 is inserted within the ring or link 26, to retain the w-agon body suspended or elevated. The Windlass is then rotated in a reverse direction, whereby the free end portion of the flexible element 23 is unwound from the drum 9. The Windlass 7 may then be removed from the wagon body. 1t is thus seen that a single Windlass may be employed in elevating any number of wagon bodies, when used in combination with the cooperating element 23 or the like. The lever 17 is adapted to be swung inwardly during the rotation of the Windlass 7, so that its head 19 will engage the flexible element 23, to lock the Windlass against rotation. This is quite convenient in case the operator should desire to leave the wagon body before the same had been completely elevated.

It is to be understood that the form of my invention, herewith shown and described, is to be taken as a preferred example of the same, and that certain changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.

Having described my invention, I claim A hoisting apparatus for wagon bodies, comprising a rotatable shaft adapted to be detachably connected with one end of the wagon body to extend longitudinally thereof, a spool formed upon the outer end of the rotatable shaft and provided with spaced heads, the outer head being provided with a slot extending inwardly from the outer edge thereof to detachably hold one end of a flexible element adapted to be wound upon the spool between the heads and to be connected with the wagon body, a radial extension formed upon the outer slotted head, an operating lever having an inner enlarged portion provided with an elongated opening to receive the radial extension, means 'pivotally connecting the inner enlarged portion of the operating lever with the radial extension, an inwardly extending catching finger adapted to engage with the flexible element and carried by the operating lever, and an outwardly extending handle carried by the outer end of the operating lever.

In testimony whereof I afiix my signature in presence of two witnesses.

ALVIN L. COX.
