To all whom it"may concern:

Be it known that I, AVELINO FERNANDEZ Roons, a subject of the King of Spain, of No. 18 Loinaz del' Castillo St, Manzanillo, Cuba, have invented certain new and useful ,Improvements in Hoisting Apparatus, of

which the following is a specification.

The invention relates to a hoisting apand particularly to an apparatus for loading and unloading vehicles with bulky goods or articles.

It is an object of the invention to provide a hoisting apparatus which may be conveniently installed and removed with respect toa vehicle or a number of vehicles so that the goods of one vehicle may be transferred onto another or a vehicle may be loaded or unloaded.

A further object of the invention consists therein that a carrying frame adapted to receive the goods is provided on the hoisting apparatus such that by a simple manipulation of acontrol device the frame together with the goods 'is raised, thence shifted laterally, and thence, lowered so that the transferring of a load from one place to another or from one vehicle to another may be conveniently and efficiently effected.

A further object of the invention aims at the provision of means for securing the goods in raised position to prevent'their return to initial position under their weight.

With these and other objects in view, which will become apparent as the description proceeds, a preferred embodiment of the invention is;illustrated in the accompanying drawing, described in the specification, and particularly pointed out in the claims forming a part thereof.

In said drawings, Figure 1 is a side view ofthe hoisting apparatus constructed in accordance with the invention Fig. 2 is a view of the front tripod constituting a part of the structure;

Fig. 3 is a view of the rear tripod;

Fig. 4 is a side view of the pulley wheels from which the carrying frame for the goods Fig. 5 is a front view of the parts'shown in Fi 4.

Re erring to the several views of the drawing 1 designates the front member of the structure for hoisting goods, which member comprises an I-beam laterally secured by braces 2. The latter intermediate their ends are inter-connected with the I-beam 1 by a Specification of Letters latent.

horizontal bar. 3. Coacting with the front member 1 is a, rear member 4 somewhat higherthan the fore front member and constructed in a similar manner. The member 4 also comprises an I-beamwhich is supported from the ground by lateral Jbraces 5 which together with'the central member 4 constitute a tripod. A transverse bar .6 connects the .I-beam 4 with intermediate portions of the braces 5.- As indicated inFig. 1, the members 1 and 4 are secured to the ground 'in inclined upwardly converging position and the upper ends are interconnected by a longitudinal I-beam 9 which-is secured to the appertaining members in any approved or desired manner, preferably by riveting, as shown at 7 and 8. The structure is preferably so arranged that'the inclination for the beam '9 is 22 as, from practical experience, it has been established that the apparatus operates most satisfactorily if the upper flange 10 of the I-beam 9 forms the angle of 22 with a horizontal plane. The load-carrying frame comprises bars 11 and 12 arranged respectively ateach side of the Ibeam 9 and depend from a horizontal shaft 13, protruding from a pulley wheel 14,which is equipped withend flanges 15 and 16, and travels on the upper flange 10 ofthe I-beam 9. To the inner side of the bars 11 and 12 horizontal bars'17'and 18 are secured which at the extremities receive shafts 19 and 20 of pulley wheels 21 and 22. 'On'the 'fiange 10 of the upper beam abutments 23 and 24 are arranged to limit the range of movement of the pulley wheel 14 and therewith of the load sustained-thereby. Brackets 25 and 26 are secured to the beam 9 and the member 4, respectively, and constitute a journal for shafts 27 and 28, respectively, carrying pulley wheels 29, 30 and 31, 32, as clearly appears in Fig.1. The load-engaging and carrying frame 33 is secured to a running block 34 equipped with a pulley 35, around which a cable is trained. The winding drum for the cable is supported in bearings 38 secured to the ground. A. shaft 39 carrying drums 40 and 41 is j ournaled in the bearings. The larger drum 40 winds up or pays out the cable 42 whereby the hoisting apparatus is actuated. A bra 43 is arranged on the shaft 39 and provided with a control lever 44 whereby the rotation of the drum 40 is controlled. The load-controlling cable 45 is wound on the drum 41 in a direction opposite to that of cable 42; i$ then trained around the pulley wheels 30 and 32; is then led over the pulley 22 to encompass the pulley 35, thence is carried around the pulley 21 and is secured at 37 to the running block 34. In order to secure the load at the'highest position, a counter-weight 46 is secured to a cable 47 which is trained around the pulleys 29 and 31 and is secured at its end at 48 to the bars 11 and 12. The counterweight 46 has dependingtherefrom a hook 49 adapted to engage the staple 50 secured to the ground. -When' the hook 49 engages the staple 50 the load will occupy the highest position such that the pulley 14bears against the abutment 24 on the inclined member 9.

Inthe operation of the device when it is desired totran'sfer the load from a cart 151 to a car 53 the brake lever 44 is manipulated to permit rotation of the winding drum and unwinding of the cable whereby the running block 34 and the frame 33 will descend until the chains 54 can be arranged around the load. Subsequently, the cable 42 is wound on the drum, either manually or by deriving motion from a suitable source of power and I duringthe' rotation of the winding drum 40, the drum 41 moves in concert whereby the load will be raiseduntil the pulley wheel meets the wheels 21 and 22. The ascent of the load will then stop-and the continued revolution of the drums and 41 will cause movement of the bars 11 and 12 so that the load travels laterally on the longitudinal member 9 and reaches the highest position. This lateral motion comes to a stop when the pulley wheel 14 engages the abutment- 24, in

which position then the hook 49 of the counterweight 46'will engage the staple 50, and thus prevent lowering of the load. After the load has been shifted to its uppermost position the brake is again released whereby the load may descend until it is placed in the car53.

The drawingdisclosesa preferred embodiment of the invention without, however, disclosing all of the possible modifications which may be adopted within the spirit of the invention. I, however, do not limit myself to the constructional features, as shown, but desire to avail myself of any changes,

alterations and modifications constituting cured to the upper end of the higher oblique member, a carriage movableon said beam a loop, a running block arranged insaid loop and provided witha pair of pulleys, a cable trained around said pair of pulleys to form and having one end of said cable secured thereto, a windingdrum from which. said cable originates, said cablebeing trained around said second pulley and around said first named pulley to provide thereby successively raising orlowering of the-running block and lateral movement of said scarsaiddrum. v Id 2.
