LOADING AND UNLOADING DEVICE.

Specification of Letters Patent.

Patented Sept. 18, 1917.

Application filed July 17, 1916. Serial No. 109,844.

To all whom it may concern:

Be it known that we, DANIEL G. HARRIS and GARRETT O. MAsoN, citizens of the United States, residing at Homer, in the county of Dakota and State of Nebraska, have invented certain new and useful Improvements in Loading and Unloading Devices, of which the following is a specification.

This invention relates toimprovements in devices for handling grain and like proclucts in bulk, and has for one of its ob ects to provide a device whereby grain and like products or commodities may be economically handled.

Another object of the invention is to provide a receptacle for the grain, or like products, and means for holding the receptacle in upright position during the transportation, and with means whereby the receptacle may be quickly overturned to discharge its contents.

With these and other objects in view, the invention consists in certain novel features of construction, as hereinafter shown and described and then specifically pointed out in the claim; and in the drawings illustrative of the preferred embodiment of the invention:

Figure 1 is a perspective view of one of the receptacles in upright position, or in the position it will occupy when carrying its 102.

Fig. 2 is a side elevation of one of the receptacles in section and in overturned position.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Each receptacle comprises a body portion 11, of sheet or plate metal, as light as possible consistent with the strains to which the receptacle will be subjected. The body portions 11 are open at the top and with closed bottoms 12. Surrounding the body portions 11 at the bottom is a reinforcing band 12, while a similar reinforcing band 13 surrounds each body portion 11 at the top. The members 1213 are disposed externally of the body portions 11 so that projecting rims are produced at the upper and lower ends of each receptacle. The bands 1213 perform the two-fold function of a support for the receptacle and at the same time as spacer members to hold the rela tively thin body portions 10 separate one from the other when the receptacles are disposed side by side.

Bearing beneath each of the receptacles is a reinforcing member 15 upturned at the ends, as shown at 16, and perforated toreceive the portion 17 of a lifting member, the latter extending through corresponding apertures in the side walls of the body 11 and spaced from the bottom 12 of the receptacle, as shown more clearly in Fig. 3. side members 18 of the lifting member terminate in eyes 19 to receive corresponding eyes 20 in a bail member 21. When the receptacle is in upright position, or loaded, the portions 18 of the lifting member will extend in parallel relation to the sides of the receptacle, as shown in Fig. 1, with the bail extending over the upper or open side of the receptacle. The member 15 with its apertured portions 16 is located at one side of the center of the receptacle, so that a greater portion of the receptacle is located at one side of the lifting members and the bail, to cause the receptacle to automatically overturn when the members 18 are released. Means are provided in the improved device for holding the receptacle in locked relation to the members 18 during the transportation, and this holding means consists of a plate 22 riveted or otherwise attached, as shown at 23, to one end wall of each receptacle. At one end the member 22 is outturned, as shown at 25, and is curved outwardly near the other end, as shown at 2 1, to engage around the adjacent portion 18 of the lifting member, as shown more clearly in Fig. 2. Beyond the curved portion 24 the body of the member 22 is curved inwardly toward the adj acent face of the receptacle, as shown at 26, and thence directed outwardly substantially in parallel relation to the outwardly extended portion 25. The rivets 23 being located near one end of the member 22 the latter forms a yieldable clasp or catch to engage the adjacent portion 18 of the lifting member. The member 22 will be heavy enough to exert a sufficient force to hold the receptacle in engagement with the lifting member while the load is being transported. A rod 28 extends at one end through the outwardly directed portion 27 and extends slidably through the projection 25 and terminates in an eye to which a pull'cord or like device, represented at 29, is applied. When the load is in the receptacle the mem- The her 22 will be engaged with the adjacent portion 18 of the lifting member, as shown in Fig. 1 and will be retained in this position until the load is to be dumped. When the latter operation is to be performed a pull upon the member 29 will cause the rod to slightly draw the curved portion 24. outwardly and at the same time exert a pulling force upon the upper portion of the receptacle and thus release the latter from the portion 18 of the lifting member and permit the gravity of the load to overturn the receptacle into the position shown in Fig. 2, and thus discharge the load. When the receptacles are to be again loaded it is only necessary for the operator to turn the receptacle into vertical position when the curved portion 25 of the member 22 will be displaced by the portion 18 which will then be disposed in its seat 2% and hold the receptacle in vertical position.

Any suitable means may be employed for handling the receptacles when loaded such as a crane, derrick or like suitable mechanism, but as these devices form no part of the present invention, it is not deemed necessary to illustrate them.

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

A device of the class described comprising a receptacle open at one end, a lifting member swinging-1y connected to the recepta cle and including vertical portions, a catch device of resilient material connected near one end to the receptacle and with outturned ends and a curved seat to engage one of the vertical portions of the lifting member, and a pull rod connected to one of the out-turned ends of the catch device and slidable through the other outturned end.

In testimony whereof we affix our signatures.
