On each side of the aper. 50 acters Ihave-indcatedmy improved hoisting apture 31 the standard includes bracket members paratus generally at IU. `As shown the device I3 38 Which support shafts 39 and vil having wire includes a triangularly shaped channel ironrope pulleys 4| and 42` thereon. n frame l2 having a plank deck |3 thereon. One The tubing 35 `is adaptedto support a mast 43 55, side of the triangular frame l2 forms the front which is made up of a plurality of separable sec- 5ftions 44 and a crown member 45. Each of the mast sections 44 comprises a length of tubing 45 split lengthwise as at 41. (See Figs. 9 and 10.) At the lower end each of the sections 44 has a length of smaller size tubing 48 split as at 48 and welded therein with a predetermined length thereof protruding from the end of the tubing 46. Opposite the splits 41v and 48' each of the mast sections includes a key member 49 protruding downwardly from the lower end of the tubing 46.` (See Figs. 9 and 13.)

At the upper end each of the mast sections has a clamping collar 50 thereon which is secured tov the tubing 46 as by welding. On each side of the tubing split 41 the collar 50 includes outwardly extending ears 5| each of which has an aperture 52 therein. Above the aperture .52 one of the ears 5I has an aperture 53 therein and the other ear has an aligned threaded aperture 54 therein. vPositioned in thev apertures 53 and 54 I provide a bolt member 55 having an enlarged head 56 thereon. Opposite the ears 52 thetubing 46 has a recess 58 therein opening through the upper end of the tubing to receive the key lmember 49 of the mast section thereabove. Opposite the split 41 each of the mast sections has a guide rail 59 thereon which is shown as an I-beam welded to the tubing 48.

When the mast sections are assembled the protruding tubing 4K8 of' one section is placed within the tubing 48 of the section therebelow with the key member 49 of the uppersection positioned in the recess 58 `of the lower section.

l 'I'he bolt 55 of the lowersection is then tightened thereby firmly clamping the two sections together.

As shown in Figs. l1 and 12 the crownrmember 45 includes an elongated cylindrical body portion 60 having a recess 6I therein opening through the bottom and a reduced aperture 52 opening through the top. At the bottom of the recess 6| I provide a key member 63 which is adapted to be positioned in the recess 58 of the uppermost mast section.

Extending upwardly and outwardly from the body on the4 same side as the key 53 the crown member includes a pair of spaced webs |54. Above the body aperture 52 v I 4provide a wire rope pulley 65 mounted on a shaft 66 supported by the webs 64. Adjacent the outer end of the webs 64 and therebetween I provide a wire rope pulley 61 mounted on a shaft 68 supported by the webs 64'.

A wire rope or lcable 63 is positioned over the

pulleys

65, and 61 the mast 43 and is rove under the pulley 4| and over the pulley 42 and extends downwardly through an aperture 59 in the deck I3 where it is rove under a` pulley 10 and then extends forward and'is wound on a reel 1|.

The pulley V1|? is rotatably mounted on a shaft I 12 which isv supported inv suitable bearing portions on spaced channel members 13 which are secured to and depend fromI the channel 21 and from another transverse channel iron l14 which `is spaced a predetermined distance Vfrom the front channel of the frame I2. I

The reel 'II is mounted on a shaft 15 one end of which is journaled in one bers I4 and the opposite end is journaled in a bearing member 116 `which; depends `from the frame IZ and is secured thereto as by welding. On one side the reel 1I includes ya 'brake drum Tlwhichis engaged'byA suitable brake lining on a brake band 18. (See Fig. 8.) One end of the and between the webs 64 l and' extends down 'through` of the bearing membrake band 18 is anchored to the frame I2 as at 19 and the opposite end is suitably secured to a crank portion of a shaft BIJ which is supported in bearing members 8| on the frame I2. The shaft extends through a suitable aperture in the side channel of the ltrarne and has an upwardly extending arm 83 mounted on and secured thereto. .l

One end of a rod 84 is suitably connected adjacent the upper end of the arm 83 and the opposite end is suitably connected to an operating lever 85 intermediate the length thereof. (See Fig. 7.) lever 85 is pivotally connected as at'86 to a bearing member 81 mounted on the deck I3.

The free end of the cable 69 hasa hook member 88 thereon which is adapted to be engaged by the bail member'89of a bottom gated bucket 90.

For guiding and steadying the bucket 80 in its upward and downward travel I provide a guide carriage which is indicated generally .atSI and shown in detail in Figs. 9 and l0. As shown the guide carriage SIfincludes a body portion consisting of a flat plate 92.` vAdjacent the top and bottom the plate'92 has a pair of spaced arm members 93 extending therefrom' towards the mast 43 on each-side of the guide rail 59. Rotatably mounted on the end .of each of the arms 93 I provide a roller 94 which is adapted to engage the web of the guide rail adjacent the outer flangethereof.` Each pair of the arms 93 supports a shaft 95 on which is mounted a rollerl 96 which engages the outer surface-of theouter flange of theI guide rail 59.

Adjacent each set ofarms 93 the plate 92 has a pair of spaced arms 91 extending `therefrom- 43 on each side' of the guide |00 between the bosses 39 I provide a. latch member |84 which includes a hook portion |05 adapted to engage the inner surface of the rear wall of the bucket and1 has a lug |06 thereon which is adapted to be positioned in the bucket aperture I 03 and in. the plate aperture |02. l x

The latch |04 allowsthe bucket to hang plumb from the hook 878 and prevents it from swinging away fromthe guide carriage 9| while the guide cart prevents the bucket from striking the mast The mast 43 is adapted toI be retained in a true vertical position-by three stays which are indicated generally at |01@ Each of the stays |01 includes a turnbuckle |08, one end of which is anchoredl to the frame I2 by an eye bolt |08. Each of the stays I 01 is formed of a plurality of steel cable sections |09 each of which has an eye I II! at one end and a hook member I |2 there- Adjacent the ends thereof 'each of the.V

of arms 93 each has an7 has an aperture |02 therein and" Adjacent the lower end the operating mounted on the deck I3.
