Oct. 28, 1941; T. F. ALLEN BASKET, TIPPING APPARATUS Filed Feb. 6, 1959 IN VEN TOR.
A TTORNEY Patented Oct. 28, 1941 UNITED STATES PATENT OFFICE [A 2,260,697 1 7 BASKET THPINGAPPARATUS Thomas F. Allen, meth ne, Calif. Application February 6, 1939, Serial No. 254,7s1-
i Claims. (01. 214-11) tion are made apparent in the following speci- The present invention relates to a basket tipping apparatus and particularly to apparatus for handling large baskets for lettuce or other vegetables.
In Patent No. 2,136,068 for Means for handling harvesting apparatus, which issued to me on November 8, 1938, and in Patent No. 2,129,394 for Basket tipping apparatus, which issued to me on September 6, 1938, there is disclosed, in connection with apparatus for handlinglettuce and like vegetables, a system which includes the use of large baskets for transporting lettuce from the field where it is cut to trimming and packing sheds. The system also includes mechanism for tipping these baskets after they have been removed from the truck which transports them so that their contents are readily accessible to workers at the trimmers benches.
is made to the accomthe apparatus illustrated in Figs. 1 and 2.
-.Referring first to Figs. 1 and 2, thecradle which supports the basket to be tipped is shown as comprising spaced members l0 bent to con-- form to the'front of the basket and to the bottomof the basket, the shape of the basket being Tipping apparatus of the kind disclosed in the above-mentioned patents forms the subject matter of the present invention. It has been.
customary, as described in said patents, to provide a pivoted cradle over which the baskets may be positioned and a pneumatic or hydraulic hoisting mechanism to engage the cradle, to tip it and the basket supported by it to suit the convenience of the worker who is removing the contents of the basket. In some cases the lifting mechanism is supported overhead by the roof structure of the packing shed, and in other cases it may be supported below the floor upon which the tipping apparatus stands, and usually secured to the beams which support the floor. In both cases the strain of the tipping operation is placed upon the building, and as the baskets are large and very heavy when-loaded, this has certain disadvantages, particularly in classes of buildings which are not sufficiently strong to stand this additional strain.
It is the object, therefore, of the present invention to provide a basket tipping apparatus which may readily be installed in any building without imposing the strain of hoisting ortipping on the building itself and which is so constructed that it will eliminate the necessity of bracing or remodeling of the building in which it is installed.
A further object of the invention is the provision of simple apparatus of inexpensive but durable construction that may be installed in illustrated in dotted lines in Fig. 1. The members l0, preferably formed of structural steel and shown as channel-shaped, are three in number and are joined in spaced relation by means of transversely extending bars shown at II. The cradle is sufficiently narrow to permit a baskets being rolled over it with its casters, shown at 12 in Fig. 1, disposed outwardly of the two outermost members Hi. This cradle is pivotally supported by means of a pair of bearings I3 secured to the two outermost members I0 (see also Fig. 3), which bearings are rotatably mounted on a horizontally disposed bar 14 supported by a floor stand. The floor stand is shown as comprising vertical posts I5, each having a horizontally disposed base member l6 extending therefrom, and a diagonal brace member H ex--' tending between the vertical post and the base member. Preferably a base plate shown at I8 in Fig. 3 underlies all of the base members I6 only, and may be substituted by a hydraulic ram all classes of buildings and that depends on or power driven jack of any suitable type.
The lower end of the ram 2| is pivotally supported-as shown between the lower ends of a pair of V-shaped braces generally indicated at 23. These braces, which are formed of angular or other suitable type of structural steel, are supported from their upper ends by means of bolts 24 which extend through the floor 20 and through the base member I6 of the stand which supports the cradle. These bolts 24 therefore serve to secure the stand in position and to support the downwardly extending framework which carries the pneumatic ram 2|. The piston of the ram is pivotally connected through the usual connecting rod and a pin 26 at the outer end thereof to plates 21 and 28 which are welded to opposite sides of the central member ID of the cradle. Consequently, when the connecting rod of the ram is extended, the cradle and basket supported thereby will be swung upwardly to the position indicated in dotted lines in Fig. 1, or to any desired position between that shown in full lines and that shown in dotted lines. The upper ends of the upright members It] are provided with lips or hook portions m, which hook over the top edge of the carrier and act as stops to retain.
the carrier or basket when the apparatus is in dumping position.
In order to. control the operation, of the ram, athreez-way valve 30 is provided with direct air under pressure to the lower end of the cylinder. This valve has a connection 3| leading to a source of supply of compressed airand is connected by a conduit 32 with the lower end of the ram. The valve also includes an exhaust port 33 and a control lever .34 is operable to manipulate it in such a manner that the compressed air will be directed into the. cylinder or will be permitted to escape from the cylinder through the. exhaust port 33. For convenience in operation foot pedals 35 are connected with opposite ends of the valve: control lever 34 and project to a position just above the floor 20 .where they may be operated by the foot of. a. worker .standing adjacent the basket tipping apparatus.
. One of the principal advantages of the structure above. described is that all strain resulting from the lifting or tipping operation of the ram 23! is confined to the apparatus itself and notimposed onany remote part of the building structure, such as the roof beams or floor joists. Plate l8 ,.which is not necessary to successful operation, is desirable for the purpose of providing a good footing for the heavily laden stand and for distribution of the weight of the stand over a large area. They perforation 19 in the plate may be relatively small to accommodate the connecting-rod of the ram while the basket is being tipped.
. With this construction all of the parts may be fabricated without regard to the particular building in which they areto be installed and without the necessity of special bracing being applied in the building to withstand the strain and vibration of the basket tipping operation. The lifting ram is disposed at such an angle by virtue of the support by the V-shaped brackets exposed beneath the floor that. little space is required for a good leverage and this positioning of the ram also facilitates the use of a conveniently positioned, foot operated control valve.
Another important advantage of the structure described above. is that the entire basket tipping apparatus may conveniently be moved fromone building to another so that where the commodities which are packed with the aid of this apparatus are grown at widely separated localities, the equipment may be transported from time to time and the harvests of several localities may be taken care of with the single set of equipment.
The above description is illustrative of the invention but should not be taken aslimiting the invention to the. particular form thereof shown and described, as this form may be variedwithin the scope of the appended claims.
Having thus described my invention, .what I claim and desire to secure by Letters Patent is:
