Application filed January 22,1918. Serial No. 213,245.

To all whom it may concern:

Be it known that I, ANDREW EBEnsoLn, a citizen; of the Unite'd 2 States, residing at Dodge City, in the county-of Ford and State of Kansas, have invented a new=and useful Portable Transferring-Derrick, of which the -fOll0W1Ilg-1S 2t SPGQlfiOZttlOIl.

My invention relates to portable -transferring derricks, which are employed to hoistyconvey and transfer farm products from point to point, as froma reapingmachine to astack', The objects of my invention are to provide a cheap, durable and portable transferring derrick for farm' use.

I attain these and other objects by means of the mechanism illustrated" in the accompanying drawing in whichFigur e 1, is a side elevation of the derrick, partly {sec it tioned to disclose the method of pivoting the mast; Fig. 2, is a top plan view of the derrick, the mast being shown in cross section at the supporting platform, and showing the cable runway channel and the ring which holds the cable in the channel; Fig.

3, is a top plan view of the rigid arm, and

showing the inner end thereof straddling the mast; Fig. 4, is a vertical elevation of the mast, and showing the cable runway channel in its side, and Fig. 5, is an end elevation of the derrick, and showing the hoist attached to the mast, the upper platform being broken away to disclose the cable runway channel and the position of the detaining ring, the rigid arm and hoisting rigging being omitted.

Similar numerals of reference refer to corresponding parts throughout the several views.

The runners 1, cross ties 2, cross rods 3, cross-tree 4, and anchor eyes 5, constitute the sled or drag for transporting the organized mechanism from place to place about a farm. A platform 6, is secured on the cross ties 2, and spaced apart from the inner sides of the runners 1, a little distance. The platform is of a thickness best adapted to have formed centrally therein a substantial pivot bearing 7, provided with a supporting shoulder 8. Inwardly and upwardly extending inclined standards 9, are fixed at their lower ends to the corners of the platform 6, their upper ends being connected by cross ties 10. The preferable height of the posts is a distance in excess of the middle of a mast hereinafter described. A platform 11, having a central opening 12, is secured on the upper ends of the standards. A vert1ca'lly'- extend-mg revolubly mounted mast 13, havinga pivot 14, entered in the pivot *bearmg 7, and a shoulder 15, bearing on the shoulder 8;, is extended upwardly through "the opening in the platform '11, and thereabove a suitable distance. The mast is, preferably, made of a circular timber of maxi- 1 mum strength and minimum weight An inwardly curved channel 16, is' formed longitudinally in themast, so that the channel 51151 11 extenda distance above and below the platform 11, f0r=apurpose that will hereinafter' be explained; A metal ring 17, is demountab-ly secured on the mastfin such a manner that itwill traverse the channel '16, and enter the opening 12, in the platform 11, and bear on" the vertical face of theopening andslide thereon in the revolving of the mast. An outwardly extending upwardly inclined arm 18, is fixed at its inner end to the mast by bolts 19, which pierce the arm and penetrate the mast, or any other fastening means. A brace 20, is rigidly connected between the mast and arm to provide added strength and support to assure the integrity of the arm. The arm 18, is formed of a pair of side members 21 and 22, which are, preferably made of suitable timbers having their outer ends united and their inner end portions spaced apart and respectively fixed to opposite sides of the mast. Cross ties 23, are connected between the side members at points adapted to lend rigidity to the arm. A pulley 24, is mounted on the under side of the outer end portion of the arm, and a similar pulley 25, is mounted on the mast below and adjacent the arm. A hoist 26, is mounted on the lower portion of the mast at a point best adapted for manual operation. The hoist comprises a frame 27, which is attached to the mast, a revoluble shaft 28, provided with a drum 29, and a gear wheel 30,'the latter being engaged by a pinion 31, on a revoluble shaft 32, having a crank 33. A cable 34, is attached. to the drum 29, and is extended upwardly into and through the channel 16, behind the ring 17, and over the pulley 25, and pulley 24, and thence to earth. A hook 35, is secured on the outer end of the cable, and a similar hook 86, is loosely mounted on the cable, so that it may slide thereon and be adjusted to and from the first mentioned hook. A flexible barge covering 87, is detachably mounted on. said hooks, and is adapted to receive a load of arge, wagon, or other vehicle, or upon the ground, and is then loaded. When loaded, the hook 35, is attached to one end of the covering and the free hook 36, is attached to its opposite end. The hoist is then operated to lift the load, the gravity of which resists to the utmost the pull of the hoist, thereby the hook 36, is forced to slide toward the hook 35, and the covering is drawn together over its load and the mass lifted. lVhen the mass is free, the mast is revolved by a pushing or pulling pressure applied to the hoist frame, thus the load is transferred to the stack or other selected point and discharged by detaching the hook 36. The cable 34, being detained in thechannel 16, in the mast, is carried by the latter within its bearing in the platform 11, and without interference with the mast support. The

simplicity of the derrick, combined with a hoist adapted for exerting great leverage, provides a cheap, useful and eflicient farm derrick which may be operated by youthful ,members of the family when labor is scarce.

Having described my invention what I claim is l V In a portable transferring derrick, the combination with the mainframe and the mast pivoting on the lower portion of the frame and having a cable runway in its side, of a plate disposed horizontally on the upper end of theframe and having an opening for loosely receiving the mast, and-a ring demountably arranged on the mast over the cable runway therein and journaled in said plate.
