ODI-S ARNOLD BROTVN, OF SANTA ANNA, TEXAS.

COTTON-BAG EMPTIER.

Application filed August 10, 1915.

To all whom it may concern:

Be it known that I, Oois A. Brown, a citizen of the United states, residing at Santa Anna, in the county of Coleman and State of lexas, have invented new and useful Improvements in Cotton-Bag Emptiers, of which the following is a specification.

This invention relates to cotton bag emptiers, and it has for its object to produce a simple and efiicient device in the nature of a portable derrick, whereby bags that have been filled with cotton by the pickers may be conveniently hoisted and their contents emptied into a wagon box, dispensing with the necessity of each picker climbing on the wagon box for the purpose of emptying his bag and thereby saving much valuable time and strenuous labor which may otherwise be more profitably employed.

A further object of the invention is to produce a hoisting frame of simple and improved construction with which the bag may be conveniently connected for hoisting, means being provided whereby the top of the bag may be released when the proper position has been reached, so as to cause the contents to be dumped.

A further object of the invention is to provide simple and improved means whereby the derrick frame may be connected with a wagon box of any height, and whereby the derrick frame may be rotated and secured at the proper adjustment.

WVith these and other encs in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention it being, however, understood'that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifictions within the scope of the claims may be resorted to when desired.

In the drawings, Figure 1 is a perspective view of the derrick member of the improved device. Fig. 2 is a perspective detail view, enlarged, of the hoisting frame and related parts. Fig. 3 is a view in elevation of the hoisting frame having the bag connected therewith. Fig. 4 is a view similar to Fig. 3, but showing the bag arranged for dis- Spccification of Letters Patent.

charging its contents. Fig. 5 is a detail new of the bag.

Corresponding parts in the several figures are denoted by like characters of reference. Referring to the drawings, designates a derrick beam having at its lower end a ground engaging flange 17 to engage the surface of the ground so as to prevent the beam from entering into the soil when the latter is soft. The beam 15 has at its upper end an arm 18 which is reinforced by a brace 19. Said beam is also provided near its upper end with a loosely fitting collar 20 with which are connected guy ropes or wires 21, the lower ends of which are connected with stakes 22 which may be readily driven in the ground for the purpose of sustaining the derrick in position. Secured upon the derrick beam 15 at a proper elevation above the ground by means of a clamp 23 is a lever 2-l by means of which the derrick beam may be rotated about its axis, said lever having at its free end a hook 25. A sleeve 26 slidably engaging the beam above the clamp 24, on which it normally rests, is provided with arms or braces 27 pivotally connected therewith, said arms or braces having terminal hooks 28 which may be equipped with set screws 29, these hooks being adapted to engage the edges of the wagon box, not shown. These arms will not only serve to space the derrick beam properly from the wagon, but will also materially assist in maintaining the derrick beam in an upright or vertical position for operation.

The arm 18 at the upper end of the den rick beam supports a pulley 31 over which is guided a flexible hoisting element, such as a rope or cable 32, one end of which carries the hoisting frame H. The latter, as seen in. the drawing, consists of a triangular frame formed of a stout metallic rod or wire, said frame being provided at the apex thereof with a loop 33' for the attachment of the hoisting rope 32, and at each of its lower corners with an eye 34 with which a hook 35 is connected. The base member 36 of the frame H supports a hook member 37 which is bent rearwardly therefrom and with which is pivotally connected, at 38, a lever having an upwardly extending arm 39 and a downwardly extending arm 40 with which latter a trip rope ll is connected. By the construction shown the hook member is composed of spaced side members between which the arm 39 of the lever may swing when a cotton bag is mounted thereon, as seen in Fig. 8.

The cotton bag used in connection with this invention, a specimen of which is shown at B, is provided at its lower corners with rings 12 adapted to engage the hooks 35- supported at the lower corners of the frame I-I. Said bag is also provided with the usual shoulder strap or carrying strap 43 which is incidentally connected with and supported by the hook member 37 when the device is in use.

In the operation of this invention, the derrick member is erected closely adjacent to a wagon box which is driven to a convenient point in the field. It is obvious that by raising or lowering the clamp 23 which supports the sleeve 26 having the brace arms 27, the device may be adjusted to operate in connection with a high or low wagon box, as may be required. The pickers having filled their bags will carry them to the wagon box. To hoist a bag the strap 43 is engaged with the hook member 37, and the lower corners of the bag are lifted, the rings 12 being connected with the hooks 35. During this part of the operation, the derrick beam is arranged with the arm 18 in parallel relation to the side of the wagon box. By pulling on the hoisting rope 21, the bag is now hoisted to the requisite height, after which by laying hold of the lever 24, the derrick beam may be swung about its axis until the arm 18 extends laterally above the wagon box, in which position it may be secured by engaging the hook 28 with one of the brace arms 27. By pulling the trip rope t1, the strap 43 will now be disengaged from the hook 37, and the mouth of the bag will. swing downward, causing the contents to be emptied into the wagon box, after which the derrick beam may be swung about its axis until the arm 18 assumes a position substantially parallel to the side of the wagon box, when the frame H and the bag connected therewith may be lowered and the operation repeated.

It will be seen from the foregoing that I have devised a very simple and effective construction and arrangement of parts whereby much of the hard and unprofitable labor in the cotton field may be dispensed with and the strength of the pickers conserved for more useful purposes.

Having thus described the invention, what is claimed as new, is

1. In a device of the class described, a hoisting frame of triangular form having a loop at its apex, and eyes at the lower corners thereof, a hoisting element connected with the loop, and hooks supported by the eyes, the base member of said triangular frame being provided with a hook member bent rearwardly therefrom and comprising spaced side members, and a stripping lever pivotally connected with the hook and hav in an arm operating between the side members. V

2. In a device of the class described, a hoisting frame of triangular form provided at its lower corners with bag attaching means, said frame being provided intermediate the lower cornersthereof with a hook member and a pivotally supported stripping lever.

B. The combination with a cotton bag having a strap near the mouth thereof, of a triangular hoisting frame and hoisting means for elevating said frame, the latter being provided at the lower corners thereof with means to support the lower corners of the bag, and intermediate said corners with a hook for engagement with the strap, and means for stripping said strap from the hook.

In testimony whereof I aflix my signature in presence of two witnesses.
