FRANK JONES, OF SALT LAKE CITY, UTAH.

BEET SCREENING, FILING, AND LOADING MACHINE.

Application filed August 19, 1919.

To all whom it may concern.-

Be it known that I, FRANK Jones, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Beet Screening, Piling, and Loading Machines, of which the following is a specification.

My invention relates to certain new and useful improvements in combined machines having means for receiving beets, or material to be handled from a wagon or other conveyance; means for screening out or separating the dirt or other foreign matter from the beets and determining the amount of said dirt; and means for subsequently piling the clean beets, or material and loading the same onto a conveyance, or depositing the cleaned material at a point of de posit.

A leading object of the present invention is to construct a machine of the type mentioned having instrumentalities for carrying out the several operations in a rapid, continuous and satisfactory manner, and with this end and other objects in View my invention consists of the parts and the construc tions, arrangements and combinations of parts as I will hereinafter describe and point out in the appended claims.

A further object of my invention is to construct a single, compact, portable machine of the tractor type, having means for receiving beets or other material directly and from conveyance on the ground, and after weighing. The gross contents of the conveyance is elevated and screened and the dirt from the beets dumped is returned to the conveyance and its amount determined, while the cleaned beets are elevated and conveyed to a pile or to cars, said machine being equipped with the necessary mechanical parts for propelling the machine over the ground and for actuating the conveying and other mechanisms, as I will hereinafter describe.

Til the accompanying drawings forming part of this specification and wherein similar reference characters indicate like parts in the several views:

Figure 1 is an end elevation of a combined loading andunloading machine embodying my invention.

Fig. 2 is a side elevation of the same.

Fig. 3 is a top plan view showing the trommel or screen and portions of the conveyers broken away.

Specification of Letters Patent.

Serial No. 818,453.

While the machine I am about to describe in more or less detail will be found useful in the handling, screening and storing of different kinds of material, I have designed it primarily to operate upon sugar or other beets; in other words for the purpose of dumping the beets from a conveyance, located on the ground, into a series of hoppers which feed the beets to appropriate conveyors, which latter are designed to elevate the beets and the associated dirt and other foreign material, to a relatively flat conveyor which transports the beets and dumps them into a trommel, or rotary cylindrical screen. During the conveying operation through this screen, the dirt which is associated with the beets is screened out or separated from the beets and the separated dirt or foreign material, is conveyed to a hopper having, if desired, a controlling discharge gate or valve.

The cleaned beets from the trommel are designed to be elevated to a pile or loaded into cars by means of a suit-able conveyer.

In said drawings, I have illustrated in Fig. 1, a conveyance which may be of any suitable character, the body a, thereof being shown in its dumping posit-ion. From the conveyance a the beets or other material drop into a series of hoppers herein shown as three in number t) the conveyance being tilted a little at a time to properly feed the beets so that they will not spill. over the sides of the conveyer with which the hoppe s communicate; this tilting of the conveyance may be effected by any suitable means and for this Urposo t have shown a, pair of pulle wblocm c, attached to a or no (Z of suitable construction, as shown in Fig. and a lli? ling-l ne which is rove throumi the pulleys and has its free end suitably connected to a winch or winding drum, f, on a transverse shaft m. To operate this shaft, a chain drive may be employed and to this end I show a chain running from the upper sprocket wheel dot the tail pulley of the horizontal or flat conveyer, 71, which I will hereinafter describe, to a lowe sprocket wheel j, on the shaft of which is a worm k, which engages a worm-wheel Z on the shaft m, said shaft and winch carrying the members of a suitable clutch a, which controls the motion of the winch. Any desired accessories of the usual type may be employed in connection with these features.

From the hoppers, b, the beets dropped thereinto from the conveyance a fall upon Cir under the hoppers b. This main frame is hinged at the points, Z, (Fig. 2) so as to be detachable and the two parts made readily portable.

The conveyer frames before described are hung to the main frame H by angle irons or equivalent structures.

The frame of the trough conveyer, p, is of any desired construction and is hinged to the main frame at the points, Y, and is supported near one end by the wheels, 0 and is detachable at the hinges Y, so that it can readily be separated for transportation purposes. The hopper and head pulley of this trough conveyer are also suitably supported. Suitable supporting agencies are also provided for the flat conveyer, h. The trommel or'rotary cylindrical screen, (Z is supported by beams running lengthwise and cross-wise; the lengthwise extending beams are hinged at the lower end P. to the main frame of the machine while the other and upper end of the trommel is connected to the elevating screw (0. before described.

The frame of the trough conveyer, f, is of suitable construction and is supported by the main frame, which also supports a cantaliver frame, Q 2) to which the upper part of the conveyer frame is attached. The two idlers, B (Fig. 2) which carry the chain drive for the trough conveyer are supported on the main frame by a channel iron or other support, R

From the foregoing description it will be understood that the machine shown has the necessary equipment to dump and receive the contents of a conveyance and to convey and elevate the same, and separate the dirt from the beets; that the oversize, represented by the cleaned beets is conveyed and elevated into a suitable receiver, and that the undersize from the screen representing the dirt, is caught by a conveyer and delivered into a hopper and finally sent back into the conveyance from which the beets were originally received, and its amount quickly ascertained.

The machine carries its own motive power and the entire operation is continuous. The machine is portable and flexible and can be moved from place to place so that it will pile beets, or other material. into any size pilethat a given area will permit; it can also be drawn alongside a string of cars and load them without the necessity of moving the cars.
