deiferring to the annexed drawings, in which the several elements are indicated `by the saine ordinals in thediiierent views, a inonorail track lis indicated by the ordinal 1 upon which travels inotor device represented by the tractor 2. Upon this tractor 2 is mounted a. hoisting device 7,'oi" which the details will be hereinafter i'ully desdiibed. in overhead suitably supported l-beam 3, a channel t secured to the `bottoni flange of said .ll-beam 3, and two angles 5 secured to the bottoni ot said channel l and 'forming bearing plates for an anti-friction roller o, journaled upon the top ci the hoisting .device 7, serve to provide a guide for the hoisting device as the tractor 2 moves longitudinally of the track 1 and to maintain the stabilit-y of the device and its load.

Thev details of the hoisting device 7 are as follows:

An outer rotatable vertical mast member 11 is provided, rectangular in cross-section, and formed of oppositely disposed structural channels 8 secured together by plates 10, Figures 4 and 5. Contained Within this outer rotatable mast member is an vinner fixed tubular mast member 9, spaced from the outer mast member 11. The rotation of the outer mast member 11, about the axis of the inner member 9, is eected by a gear 12 and associated mechanism, Figures 7 and 9, hereinafter described in detail. A boom 13, formed of structural channel members 14, is supported upon the outer rotatable mast member 11, and is capable of a movement longitudinally of said member 11 by means hereinafter fully described in detail.

Referring particularly to Figure 3, the anti-friction roller 6 is mounted upon the top of a shell member 24 secured interiorly of the xed mast member 9, by means of a pin 25, the latter having an'enlarged upper portion 26, forming` a contact surface for said roller 6. Adjacent the top of the fixed mast member 9 is formed an annular external shoulder 27, upon which rests an annular ring 28, forming a bearing plate for balls 30 and held to position by a nut 29. cap 16, having an annular shoulder 32, is secured by a bottom flange 34 to a channel 33, the latter also being secured to the members 8 and 10 of the outer rotatable mast member 11. The shoulder 32, of the cap 16, forms a stop for a ball race 31 accommodating the balls 30. It is evident thatthe detail just described provides for the rotation of the upper endof the outer mast 11 about the axis of the fixed mast member 9.

Referring now to Figure 6, the bottoms of' the channels 8 of the rotatable mast member 11 are secured to a rotatable base 18 mounted upon the tractor 2 and rotated by means hereinafter described.

The bottom of the inner fixed mast mem` ber 9 is formed With an annular enlarged base portion 15, Figure 7, secured to channels fixed to the platform 23 of the tractor 2. A gear Wheel 12 is secured to an annular plate21. The'enlarged base 15 of the mast member 9 is formed with a shoulder 19 upon which rests a horizontally disposed ball race 37, alsd With a shoulder 20 supporting a vertically disposed ball race 38. The annular plate 21 by means of an upper flange 42 holds a bearing plate 43 to the balls 40 resting in the race 38. to complete a bearing talring up the radial thrust and also holds a ball race 41 to the balls 39, thus taking up the vertical thrust. The gear Wheel 12 is secured by its face to a lateral flange 35 of the annular plate 21 and the flange 42 of this plate 21 is secured to the base 18 of the mast member 11. It is evident that the details just described assuming that means are provided for rotating the gear wheel 12 are sufiic-ient to effect the rotation of the outer mast member 11 about the fixed inner mast member 9.

The gear wheel 12 is rotated by a motor 51 mounted upon the tractor, by means of the following' detail mechanisms.

Referring particularly to Figures 7 and 9, the gear 12 meshes with a pinion 44, secured to a vertically alined stub shaft 45, journaled in suitable boxes mounted on the tractor frame. Adjacent the top of said stub shaft 45 is secured a gear wheel 46 meshing with a worm 47, formed upon the rearwardly extending shalt 48 provided adjacent its rear end with a pinion 49, meshing with the pinion 50, secured to the shaft of the motor 51.

Referring particularly to Figures 1, 2 and 4, a rectangular casing is formed of plates 36 secured together by suitable angles, said easing being disposed exteriorly of the outer mast member 11. To one side of said casing 36 are secured-boxes in which is journaled a shaft 52 carrying a. pinion 58 meshing with a rack plate 53 secured to the external face of one of the plates 1.() of the outer mast member 11. The plates 36 are formed with ears 54 within which are jonr naled shafts 55 provided adjacent their ends with anti-friction rollers 56. The channel members 14 of the boom 13 also support corresponding shafts 55, carrying anti-fricr` tion rollers 56. rThe shaft 52 is rotated from the motor 57 and its associated mechanisms, so that it is evidentv that the casing 36 will travel vertically of the axis of the mast members 9 and 11, the plates 1() of the outer mast member 11serving as bearing plates for the travel of the anti-friction rollers 56, as plainly shown in Figure 5. The casing 36 forms a support for the boom 13. so that it is evident that the vertical movement of the housing 36 will serve to raise and lower said boom. The motor 57 and its associated mechanisms, as well as cage 59, are carried upon a rearward extension 41 of the boom 13, the whole serving as a counter-balance for the boom and load. The boom 13 is further supported and steadied by angles 6() and braces 61, Figures 1 and 4.

vA pulley 62 is mounted intermediate the boom channels 14 and adjacent the ends thereof, over which runs a hoisting cable 63 carrying the tackle block 64. A rear pulley 65 is provided whence the hoisting cable runs to a drum 66 operated by a motor 67, said drum and motor and associated mechanisms being mounted upon one of the plates of the casing 36.

rThe following detailed mechanism is pro- 3 vided for operating,` the ,tractor 2. The tractor motor is indicated by the ordinal 68, Figures 6 iand 7, and the same operates, throughsuitable reduction gears 69, a shaft 70 which positively drives` the Wheels 73 of Hthe ,forward truck of the tractor and also,

Wheels 73. of the rearward truck. `i

through a pair of bevel gears71 and a longitudinal shaft `72, ,positively drivesI the nasmuch as .the drive forthe Wheels of the tivo trucks are identically the same, only one of such drives will `be described in detail, the same being' indicated in said Figures 6 and 7 and also the section shovvn in Figure 8, Secured to the inner end of the shaft 70 is a bevel Wheel "74:, meshing'iwith a bevel `vvheel 75, journaled upon a vertically disposed stub shaft 76. Upon `an extended hub on the bevel Wheel 75 is secured a bevel Wheel 77,

`meshing), `with a bevel Wheel78, secured to a transversely disposed shaft 79. To the inner end of theA shaft79 is secured a gear'yvheel 80 .meshing With Vtwo gears 81 secured to the :axles .82 of the `forward tractor Wheels 73 Itis evident that the mechanisms herein- `beforedescribed `in detail effect the travel of the tractor 2 along the monorail track 1; and `also `effect the rotation of the boom 13 andthe outer inastmember 1.1 about the axis of `the inner `nieunbei'- 9; andthe vertical `travel `of. Ithe boom 13 and its support along the outer mastmeniber 11.

`It is `evident that the construction shown 1n Figures 1 to 9, inclusive, is best adapted tonieet conditions "Where the operating rei nirenients aresatisiied b f a low ivorlrino' P3 invented so as `to `meet the requirements of range for `the boom 13., Referring to Figure 1,0, a modification is therein disclosed 1n which the boom 13 and its support, which rotate about the inner mast vmember 9p, are

u the main gbooni 13 `is an auxiliary boom y841` which is further `supported by means `of tension rods 86. ForWardlv of `the auxiliary boom 841 lthe shovel 87 is secured at its rear end to ,the forward endof a rearwardly tending;` shaft 88.. By means of a suitable sprocket VWheel (not shown) a chain 89 Opf eratively connects said shaft 88 to anupper shaft .90, disposed lntermediate the channels 141 of `the ,main boom 13', to .the rear end of which shaftA 90 issecured a gear 91, meshing with the pinion .92, secured to a` shaft (not shown), having a 4Worin `Wheel meshing with the vorrn V98 formed upon the shaft of the motor 94. lt is evident that the mechanisms just described Will .provide for the driving of the shovel 87 intoV the bulk material to fill the shovel and that the latter can be hoisted and conveyed as desired, and then dumped through the medium of the shafts 88 and 90, motor 94 and `allied mechanisms.

Referring particularly to Figures 13` to 16, there is therein shown a third modiiication in which the general application of my hoisting and conveying machine is coordinated With that of an attachment providing a dumping pan. This dumping pan is indicated by the ordinal 96.

rThe forward end of the shaft 88, similar to the like-numbered shaft of Figures 1l and 8 12, is formed with a Worm 97, meshing With a Worm Wheel 98, secured to a vertically disposed shaft 99, mounted at the end of boom 841. The dumping pan 96 is provided with a pair of trunnions 102-102 mounted in vertical extensions 101'-101 formed on a frame 100. The pan 96 is of such a formV and so hung that When empty it Will by gravity assume the position shown in full linesin Fig. 13, but, when loaded, Will automatically tend to discharge its load, as shown in dotted lines in said figure. To the bottom of the pan 96 and adjacent the rear thereof is secured a member 103 adapted to be engaged by a dog; 1011 pivotally mounted .between arms 105 extending rearwardly from the frame 100. Journaled upon pins 108 disposed within vertical extensions 106 of the arms 105 are pulleys 107 forming a guide for a cable 109 running to the cage 59. It is evident from the construction `just deH scribed that the pan 96 from any angle can be forced into `the material to be .conveyed and thus .filled `and that then the pin can be elevated and transported, as desired, and dumped at the proper place by releasingl the dog 10d from the member 103 throughthe medium of operating cable. 109.

It will be noted from the above that the rotation of the shaft 88 will effect the rota tion of the Worm 97, the shaft 99 and'hence the rotation of the pan 96 upon theaxis of said shaft` p u While l have shown and illustrated overhead means for supporting` and guiding,l the 115 upper end of the mast so as to stabilize the latter and the load carried thereby, it will i be obvious that such speciiio means may be dispensed with and the required stability supplied by increasing` the Width of the base of the device, as for instance, by supplying parallel rails and suitable trucks therefor.
