L-UMBER LOADING OR UNLOADING DEVICE.

SPECIFICATION forming'part of Letters Patent No. 707,162, dated August 19, 1902.

Application filed May 22, 1902. Serial No. 108,521. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM SAUNTRY, a citizen of the United States, residing at Stillwater, in the county of Washington and State of Minnesota, have invented certain new and are adapted for loading and unloading rail-' road-cars. I

The object of my invention is to provide a cheapand easily-constructed lumber-loader by means of which a train of cars may be quickly and advantageously loaded with logs, heavy timber, orlother material.

It consists of a suitably-constructed movable base or support having hinged thereto a derrick formed of V-shaped beams secured together at their upper ends and adapted to be raised or lowered to suit the height of the load and suitablehoisting mechanism mounted upon the platform of said base.

It further consists in certain novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described and specifically claimed.

In the accompanying drawings, Figure 1 is a side elevation of a portion of a railroadtrain, showing my improved log-loader mounted uponone of the cars; and Fig. 2 is a top plan view'of the same.

The numeral 1 in the drawings represents a portion of a railroad-track.

2, 3, and t represent three cars or trucks, which may be either the platform or the open logging-car type. v

My invention is shown upon the car 3 in position forloading car 2; The base or support 5 comprises longitudinal sills or runners 6, having beveled ends 6', suitable cross-bars], and a flooring or platform 8-for the engine and hoisting-drums.

9 and 10 denote the two beams or spars which form the derrick. Their upper ends are securely fastened together by means of tance from the ends of the runners 6, so as to balance the base. The derrick is adjustably held iu'an inclined position bymeans of the cables 14 14, having one of their ends secured to the tops of the beams 9 and 10 and having their'opposite ends wound around a drum or windlass15, located on the rear end of the base and provided with a crank for operating .thesame and apawl and ratchet for locking the Windlass. construction the derrick may be quickly and It will be seen that by this easily raised and lowered to suit the height of the'load which is to be placed on the adjoining car. In order to relieve the hinges 13 .on-the derrick of the side strain when the logs are being drawn up to the car, I provide side braces 16. One brace is loosely secured to each of the beams 9 and 10 bymeans of the eyebolts 17, secured to-the ends of the braces 16, engaging the eyes 18, formed on the metal bands 19, which are clamped to the beams. It will be seen that by this construction the braces are free to be swung to an angle to correspond tothe position of the derrick, and when the same is not in use the free ends of .the braces can be swung in and placed upon the platform,and thus be entirely outof the way. a

20den'o'tes the hoisting-cable, one end of which is passed over the sheave or block 12 and isdiVided in any desired manner to form branch cables 21; but this is preferably done by means of the ring 22. The branch cables 21, which are secured to the ring,'have attached at their ends log-engaging hooks 23, to which are secured the placing-ropes 2t.

When it is desired to raise more than one log at a time, bunch chains may take the place of the divided cable and hooks. The opposite or inner end of the hoisting-line 20 passes rearwardly from thesheave 12 and is wound around a hoisting drum or spool 25. of a hoisting-engine 27 conventionallyillustrated in the drawings.

In order to allow 'the'device to" be readily moved from one car to the next, I provide a cable 28, one end of which is wound around a winding-spool 29, operated by the engine. This cable is passed rearwardly over the top of the adjacent car at, around a pulley or block 30, which is detachably secured to the rear of said car, preferably to the coupler, as shown in the drawings, and is then brought forward and secured to one of the cross-bars 7 of the platform.

In the operation of the device when it is desired to load the car 2 the base or support is placed upon the next car 3, as shown in the drawings, and the derrick is then adjusted at the proper angle by means of the cables 14: and Windlass 15. The side braces or props 16 are then swung out to support and strengthen the derrick, the hoisting-cable 20 is paid out, and the hooks 23 are secured to the log or timber to be placed upon the car. The drum 25 is then operated to draw in the cable 20, and when the load is above the car it can be easily swung to the desired position by means of the placing-ropes 24. When the log has been deposited upon the car, the hooks 23 are disengaged and in a similarmanner this operation is repeated. hen the desired amount of lumber has been placed upon the car 2 and it is desired to load car 3, the drum or spool 29 is set in motion to draw in the cable 28. As will be readily seen, this operation will pull the base or support back upon the car 4, and the car 3 can then be loaded in a manner similar to the car 2. This operation is repeated until the entire train has been loaded. The block or pulley 30 will of course be moved back to the next car each time it is desired to change the position of the device.

It will be seen that my machine may be easily and quickly moved from one car to the next without the use of rails on the platforms of the cars and other cumbersome appliances. It will be noted that instead of employing the engine and hoisting-drums to operate the various cables I may pass them over pulleys I claim as new, and desire to secure by Letters Patent, is

1. A loading and unloading device, comprising a base composed of longitudinal sills forming runners and cross-bars bracing the said sills, a derrick formed of converging beams secured together at their upper ends by means of a ring or band and having their lower ends hinged to said sills, side braces loosely connected to said beams, cables connected to the derrick, a Windlass to which the cables are secured, said Windlass being mounted upon the base, a sheave mounted upon the apex of said derrick, a hoistingdrum mounted upon the base, a hoistingcable wound upon said drum, passed over said sheave and carrying a crotched cable having log-engaging hooks and placing-ropes secured to its ends, substantially as set forth.

2. The combination with two or more flatbottom cars, of a hoisting-rig supported by runners adapted to be slid from one car-bottom to the other, a Windlass carried by said rig, a pulley supported by one of the cars other than that upon which the rig is sup ported, a cable, one end of which is fixed to the frame of said rig, rove about said pulley and having its opposite end connected to said Windlass whereby upon the rotation of the Windlass in the proper direction the rig will be drawn from one car to the other, substantially as set forth.

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

WILLIAM SAUN TRY.
