ATTACHMENT FOR WAGONS FOR LOADING OR UNLOADING STONE.

SPECIFICATION forming part of Letters Patent No. 623,676, dated April 25, 1899.

Application filed April 4,1898. Serial No. 676,371. (No model.)

To (LZZ whom, it may concern:

Be it known that I, JULIUS IV. KNOPP,of Toledo, county of Lucas, and State of Ohio, have invented certain new and useful 1m provements in Portable Attachments for Wagons for Loading orUnloading Stone; and I do hereby declare that the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form part of this specification.

My invention relates to a portable attachment to wagons for loading and unloading stone, and has for its object to provide a mechanism transportable with the wagon, whereby when either at the source of supply or delivery the mechanism may be erected and operated to either load upon the wagon or deliver the load from the wagon to the desired place of deposit.

Figure l is a side elevation showing the truss-winch and tackle. Fig. 2 is a top plan view. Fig. 3 is a rear end elevation. Fig. 41: is a detail View showing the carrier-beam and traveler. Fig. 5 is a view in side elevation of a section of carrier-beam with the traveler thereon. and link which supports the traveler-beam.

I have constructed a wagon'with my improved attachment in which the divergent sills are of I-beam iron, and suspend the sills by stirrups 2, although I may employ the ordinary wagon constructed for transporting stone, and upon the bed of the wagon I erect a truss 3, preferably of T-beam iron, the side rail of the truss converging to a center, as at 4, and at this point I journal a sheave 5, preferably of three sections, and intermediate the length of one of the divergent sections of truss, as at 6, I journal a winch 7, over which is reeved a rope or cable 8, and mount upon the shaft of the winch a drum 9, having perforations to receive the end of a bar 11, by which to revolve the winch. The rope or cable 8 is also reeved over the sheave 5, and one or more strands are reeved over a pulley 12 of a block 13, having a link 14, in which rests one end of a traveler-beam 15, by which means when the drum 9 is revolved the traveler-beam is either raised or lowered,

Fig. 6 is a detail View of the block' as desired. The traveler-beam 15 is supported at the opposite end upon a standard 16, the base of which may rest upon the curbing 17, and is formed with notches or rests 18, into which a link 19, secured to the travelerbeam, may rest.

I mount upon the traveler-beam 15 a block 20, having a roller 21, which rests upon the beam, and in the frame 22 of the block there is passed a rope or cable 23, which acts as a sling to embrace the load 24 of stone either by being secured to metal hooks 25 or otherwise.

It will be evident that I may strengthen the framework by truss-irons, as shown at 26 in Fig. 3, or in any preferred manner.

In the employment of the skeleton metal bed of I-beams l I may provide for a resilient movement to compensate for unevenness of the road by interposing a spring 27 upon the front axle 2S, and to lend rigidity I may secure a brace-iron 29 upon the truss and allow the opposite end 30 to embrace the standard 31, upon which the spring 27 is coiled.

, In operation the wagon is driven to the source of supply of the stone, the standard 16 is erected, and the link 19 adjusted in one of the notches 18 to incline the beam 15 toward the wagon, the pulley 12 being also lowered by manipulating the winch. The sling is now secured around the stone and the beam 15 slightly raised by elevating the pulley 12 complish the work hitherto requiring three or four.

I prefer to drill holes along the top portion of the beam 15, into which may be inserted stop-pins 32 to limit the movement of the sling and load. 7

It will be understood that the drum 9 and shaft are controlled by the usual ratchet and pawl to control the winding up of the load and with a friction-brake to allow a controlat one end, the other end being adjustably supported by a standard having a serrated edge, and a traveler upon the beam adapted to travel in the direction of inclination'of the beam.

In testimony that I claim the foregoing as my own I hereby aifix my signature in presence of two Witnesses.

JULIUS V. KNOPP.
