may be shaken over the vehicle for rapidly and completely emptying said bags.

Still another important object of the invention is to provide a cotton handling apparatus of the character described which is mounted for operation on the wagon or trailer to be loaded and which may be conveniently transferred from one vehicle to another.

Other objects of the invention are to provide a cotton handling apparatus of the character set forth which will be comparatively simple in construction, strong, durable, highly efiicient and reliable in use, compact, light in weight and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure l is an elevational view, showing an apparatus in accordance with the present invention about to hoist a bag of cotton, the trailer being shown in cross section.

Figure 2 is a top plan view.

Figure 3 is a view in vertical section through the block and fall.

Figure 4 is a view in vertical section through the block and fall, taken substantially on the line 4-4 of Figure 3.

Figure 5 is a view in horizontal section through the block, taken substantially on the line 5-5 of Figure 3.

Figure 6 is a view in vertical section through the mast.

Figure 'l is a view in horizontal section, showing the means for securing the mast in position in the vehicle body, taken substantially on the line l'! of Figure 1.

Figure 8 is a plan view of a cotton pickers bag provided with rings in accordance with the present invention.

Referring now to the drawings in detail, it will 55 end portions of the casing 30.

1 erence numeral 28.

be seen that reference numeral I designates the box-type body of a trailer, wagon or other vehicle 2. Mounted in one side portion of the body I, at an intermediate point, is a mast which is designated generally by the reference numeral 3;

The mast 3 comprises a tubular post l which is permanently secured in position in the body I. Toward this end,- the tubular post l has fixed on its lower end a base 5 which is firmly bolted or otherwise secured to the bottom 6 of the body I adjacent one side T of said body. The post 4 is further secured in position through the medium of clamps 8 which are mounted on the sides 1 of the body l.

The mast 3 further comprises a plate 9 which is fixed on the upper end of the tubular stationary post 4. Fixed on the plate 9 is an internally threaded cup or socket H3. Threaded into the socket H3 is a sleeve I I. Bearings I2 are provided in the end portions of the sleeve l l and journaled in said bearings is a removable standard I3. Metallic disks l4 are fixed on the ends of the removable tubular standard 13. Extending through the disks I4 is a rod [5 having nuts threaded on itsend portions. Thenuts IS are fixed, as by welding, to the disks l4.

Rotatably mounted on the upper end portion of the tubular standard I3 is a cap ll. Guy wires l8 have one end connected to the cap l7. Mounted on the walls of the vehicle body I are eyes l9. The other ends of the wires [8 are detachably connected to the eyes l9 by means including turnbuckles having fixed on one end snap hooks 2| which are engageable with said eyes.

Fixed on the rotary tubular standard I3 is a horizontally projecting arm 22 which is provided with a suitable brace structure 23. Mounted on the outer end portion of the arm 22 is a pulley 24. An operating rope 25 has one end connected to the outer end portion of the arm 22. The operating rope 25 passes around a pulley 26 on the side of the vehicle body I which is remote from the mast 3, said rope then passing over the pulley.

24 from which it depends to a point adjacent the ground. A weight 21 is provided on the free end of the operating rope 25.

Suspended from the arm 22 is a block and fall apparatus which is designated generallyby ref- The apparatus 28 includes a double block 29 comprising a casing or the like 30 which is secured by a bolt 3! beneath the free end portion of the arm 22. J ournaled on a shaft 32 in the casing 39 is a pair of pulleys or sheaves 33. Links 34 are pivotally suspended from the Pivotally mount:

.' foregoing.

ed on the lower end portions of the links 34 is a pair of side bars 35. Paralleling the side bars 35 is an intermediate bar 36. Journaled for rocking movement between the intermediate bar 36 and the side bars 35 are rope guides 37 comprising rollers 33. Clamped longitudinally on the side bars 35 and depending therefrom are bumpers 39 the purpose of which will be presently set forth.

The apparatus 28 further includes a fall 49 which is suspended from the block 29 by a' hoisting rope 4|. The fall 49 includes an inverted hood or casing 42 having journaled on a shaft 43 therein a single pulley or sheave 44. Rising from the end portions of the casing 42 are pivotally mounted links 45. Pivotally mounted on the upper end portions of the 1inks.45 is a frame structure in the form of a pair of parallel bars 46. Rope guides 41, substantially similar to the guides 31, are journaled for rocking movement between the bars 46. Mounted on the bars 46 in spaced relation thereto for engagement with the bumpers 39 are substantially similar bumpers 48. The hoisting rope 4| is trained in the usual manner around the grooved pulleys 33 and 34. A weight 49 is provided on the free end of rope 4|.

Suspended by a swivel connection 59 beneath the casing 42 is a pair of plates Pivotally mounted at an intermediate point between the plates 5| is a bar 52. Hooks 53 and 54 extend in opposite directions from one end portion of the bar 52. A trip rope 55 is connected to the other end portion of the bar 52.

A cotton pickers bag is designated by reference numeral 56, said bag being open at both ends. Rings 51 are secured on the ends of the bag 56. A single ring 58 is secured to an intermediate portion Of the bag 56. It is thought that the manner in which the apparatus functions will be readily apparent from a consideration of the Briefly, the arm 22 is swung outwardly to substantially the position suggested in Figure 1 of the drawings and the fall 40 is lowered. When the fall 40 is lowered in this manner the weight 49 is elevated into engagement with the block 29. Thus, downward movement of the fall 49 is definitely limited and the rope 4| is maintained under the correct tension at all times. The two end rings 51 on the cotton bag 56 are now engaged in the hook 53 and the'intermediate ring 58 is engaged on the hook 54. The apparatus 28 is now actuated through the medium of the rope 4| for hoisting the bag of cotton sutficiently to clear the top of the vehicle body Through the medium of the rope 25 the arm 22 is then swung to position the bag of cotton over the body I. Then, through the medium of the trip rope the bar 52 is actuated for swinging the hooks 53 and 54 upwardly for causing the rings 5'! to slip off of said hook 53. It will thus be seen that the ends of the bag 55 are permitted to fall for discharging the cotton into the body To dislodge any cotton that may remain in the bag, the fall 49 is moved upwardly and downwardly through the medium of the rope 4| in a manner to cause said fall to rapidly strike the block 29, the bumpers 48 engaging the bumpers 39 when this is done. The construction and arrangement of the pivoted

links

34 and 45, the bumpers 39 and 48, etc., is such as to cause the bag to be thoroughly shaken when the fall 40 is caused to collide with the block 29. When the bag has been emptied the arm 22 is swung outwardly again, the fall 49 is lowered and the empty bag is removed. By disconnecting the elements l8 and. 25 from'the body the tubular standard l3 with the apparatus thereon may be expeditiously removed from the post 4 and transferred to a similar post on another vehicle.

It is believed that the many advantages of a cotton handling apparatus constructed inaccordance with the present invention will be readily understood and although a preferred embodiment of said apparatus is as illustrated and described, it is to be understood that changes in the details of constructionand in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

Having described the claimed as new is:

1. A hoist including a block, a fall, ;a rope operatively connecting said block and said fall, the block and fall each comprising a housing, pairs of links pivotally mounted on each housing, a-bar pivotally mountedon each pair of invention, what is links, a bumper mounted on each bar, and means for detachably connecting a load to the fall.

2. A hoisting block including a casing, pulleys journaled in said casing, pairs of pivoted links suspended from said casing, a horizontal bar pivotally mounted on the lower end portions of each pair of said links, and rockable guides for a hoisting rope journaled between said bars.
