i claim. (o1. 2541-1144) l This inventionrelates toa like.

The chief .object of -this invention is to provide a portable hoist structure through which a loaded vehicle may be drawn and when disposed over the same andthe tractive force such as a tractor wagon hoistand the I or a team is disconnected, the latter may be connected to a windlass or drum mounted cable so that continuation of the movement rof said ytractor or team in the .preceding direction-will result in the elevation or hoisting of that portion of the vehicle -disposed immediately above the central portion of the lifting device.

Said device is further -characterized by the fact that 4backingvup of the team or tractor, when so cable connected, automatically results in the n return or lowering of the elevated vehicle or portion thereof. When full'return is accomplished, the tractive force may be Vreconnected to the 'vehicle and tractive force applied in the same general direction as before whereupon the vehicle is passed through the hoist structure.

The chief feature of the invention resides in an open work base from which there projects upwardly two end frames spaced apart a sufcient distance to accommodate vehicles as wide as hay wagons, etc. Also associated with said base is an elevating structure, the same being pulley .and cable or rope elevated in conjunction with a drum having spaced cable or rope Winding portions and an intermediate tractive cable, chain or like winding portion. The latter being rotatable by straight-away movement of the last mentioned cable, in opposite directions for load raising and load lowering, respectively.

Another feature of the invention resides in one of the end frames being of singular character and biased braced, and the other end frame being of dual character and cross or like braced, the latter rotatively supporting the winding drums.

Another feature of the invention resides in the sled-like formation of the base to facilitate portability.

A further feature of the invention resides in the guide and cushion stop structure for the drive away cable connector or hitch.

A still further feature of the invention resides in a semi-yielding safety connection between the hoisting cables and the elevator portion of the device.

The full nature of the invention will be understood from the accompanying drawing and the following description and claims.

In the drawings,

Fig. 1 is a front view of the hoist structure embodying the invention.

Fig. 2 is a top plan View thereof.

lFig.13 is an end elevational view `at the drum or windlass end. 'y

In the drawings I0 indicates a pairof parallel .runners havingvrupturned ends lauandjsuitably Vspaced apart. Atone end is 'a single side lframe Astructure Il JandLatthe other end is a` double-or dual end frame structure .I 2 `and -I 3, suitably Y'conlnected together by cross-braces I4 and I5. Said double `end yframe is also connected together-and braced yby angle .iron supports v24 and '25. ,u

The singular .frame I IV is braced by the biased braces I Ia. Each of the aforesaid frames, at the top, mounts a .pulley-as forexample, pulleys I6, I1 andfl respectively. Approximately directly therebeneath and near the base are .the pulleys rvI,9.and120. f

' The elevator or platform comprises .a pair of members ,2| .disposed within .the open `type l'base andparallel to the members I0 thereof.I Said elevator members are connected at the ends` 'by the angle iron members 22 and may be centrally connected by a central bearing plate 23. Said angle iron members 22 carry the guide bars 26.

An elevating shaft 21 is bearing mounted as at 29 between said double end frames and secured to a support angle iron member 25. Said shaft has at each end thereof an elevating drum as at 3| and 32, see Fig. l. A windlass or winding drum 33 is rigidly mounted on said shaft between the elevating drums 3I and 32.

The winding drum 33 has a cable or rope 34 secured thereto and wound thereon. Said cable passes from the drum through a guide pulley and bracket 35, see Fig. 2, and also through a cushion stop structure 36 and into a stop member 31 and terminates in a hitch connector 38. Said connector is a loop made by doubling back the end of said cable and which is secured by clamp 39.

A cable or rope 43 is secured to elevating drum 3| and passed upwardly, and between the pulley guide 4I and pulley I1, then downwardly to and through the pulley housing 42 which supports the elevating pulley 43. II'he cable 40 is then passed upwardly and secured to the deadman 44 as at 45, see Fig. 3.

A cable 46, see Fig. 1, is secured to elevating drum 32 and passed upwardly and between the pulley guide 41 and pulley I8 and thence downwardly to and through the pulley guide 48 and pulley 20. The cable 46 then passes below the wagon elevating platform and through the pulley guide 49 and pulley I9. It then passes upwardly through pulley guide 50, over pulley I6 and down to and through the pulley housing 5I which supports pulley 52. Said cable is then passed upwardly and secured to the deadman 53 as at 54.

Pulley housing 42 or 5|, respectively is connected to a sling 55, see Fig. 3. Said sling comprises ,a cable or rope which passes from the housing aforesaid to and about the elevator members 2|.. It is secured to the housing as at 51 by suitable clamping means.

Paralleling said sling is a cushion connection comprising an eye-bolt 59 suitably secured vto angle iron member 22 on the platform, and connected to one end of a very stiff spring 60 which inturn is connected to eye-bolt 56 secured'in turn to the clamping means shown at 51. Initial'platform elevation extends these springs. The invention operates in the following man'- ner: 'The tractive force passes through -the hoist structure and positions the wagon or object to be lifted above .the central bearing plate V23. Said tractiverforc'e-is then disconnected an'd conf frames, guide means on the opposite ends of saidplatform structure embracing the legs of said end nected to the traction cable 34.VV TheY 'tractive force then moves awayfrom thehoiststructure up the two elevating cables 40 and 46 .that are securedvto the drums 3| and 32 which are rigid with s'aid shaft. The two` elevating cables when wound upon said drums will effect the raising of the elevating platform structure, thereby Velevating said Wagon. Movement of the tractive force l in the opposite direction permits reverse operation of the aforesaid and effects lowering of the wagon or load Iand platform structure. The cushion Vstop then functions as previously described.

While the invention has .been illustrated and described in great detail in the. drawings and Yforegoing description, the,V same is to Abe con'- sidered as illustrativejand not restrictive in character.

Vin a substantiallyforwarddirection, thereby Vwithdrawing the ,tractionlcable from`its drum which in turn rotatesthe shaft and 'therebywinds le of this patent:

frames, cable pulleys at the apexes of said trian- 1 `gular frames, cables passing over said pulleys,

flexible means connecting the operating ends of the cables with the platform and biasing means shorter than said first mentioned means connecting the operating ends of theV cables withlthe platform. Y
