To all whom it may concern:

Be it known that l, PHILIP HENRY STAUCH, a citizen ofthe United States, residing at Chicago, in the county of Cook and State ol Illinois, have invented a new and useful Automatic Digger and Conveyer, of which the following is a specification.

The invention relates to a combined digger and conveyer.

The object of the present invention is to provide a simple, inexpensive, and efficient ap aratus designed particularly for use in go d-i'ields for digging into sand and the like and adapted to convey such material from the place or point Where it is dug to a convenient point for separating the particles of different sizes.

With these and other objects in view the invention consists in the construction .and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it beingunderstood that various changes in the form, proportion, size, and minor details of construction Within the sco e of the claims may be resorted to without eparting from the spirit or sacrificing any of the advantages of the invention. y v

In the drawings, Figure 1 is a side elevation of a combined digger and conveyer constructed in accordance with this invention. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a detail perspective view'olf the casing ofthe combine fan and conveyer. Fig. 4 is a transverse sectional view on the line 7 7 of Fig. 2. Fig. 5 is a detail sectional view of a portion of the conveyer, iliustrating the arrangement of the outer covering of waterproof material.

Like numerals of reference designate corresponding parts in all the figures of the drawm s.

g1 designates a supporting-frame designed to be constructed of wood or any other suitable material and consisting of uprights or standards 2 and a connecting top portion 3 but any other form of frame may be employed for supporting the conveyer, and the said frame may also be provided with any suitable means for enabling it to be drawn As the comlight, it maybe convenienti carried from one point to another, as Will e readily understood.

1 1 designates a flexible conveyer consistin of a spira ly-coiled piece of resilient materia which is flat in crossesection, as clearly illustrated in Figs. 1 and 2 of the drawings. The spirally-coiled s ring, constituting the conveyer, is prefers. ly provided Withsharp peripheral cutting edges 11, and it is connected at one end wit a sleeve or hub extension 12 of a ulley 13, which may be driven by any suita le means. The front end oi' the flexible conveyer may be supported by anysuitable form of bearing, if desired, and augersections 14 may be secured within the central opening formed by spirally coiling the dat s ring of the llexible conveyer, and these s ort lengths of auger-sections 14 do not interfere with the flexibility of the conveyer, which is adapted to operate on a mass of material. The augersections it form a spirally-twisted core or central portion for the spirally-coiled conveyer-strip, and they assist in conveying the materiaf The apparatus is especially designed for operating on sandy soil in gold districts; but it may be advantageously employed for handlin grain', coal, or an other suitable materiain bulk, and the en of the conveyer may be inserted into a mass ofv material at any point, and it will'positively convey the material inward through it. The outer movable portion :of the flexible cnveyer is arranged Within a-tubularshell or casing 15, of iiexible material, adapted to oscillate with the flexible conveyer, as illustrated in dotted lines in Fig. 1 of the drawings, to enable the conveyer to operate on different portions of the mass of material,l `and the outer portion of the flexible conveyer and its inclosing shell may be of any desired length to Vermit the desired amount of movement, so t at the apparatus may o erate over a predetermined area without c anging the position of the supporting-frame. Thel au er-sections are splrally twisted, and they c ose the central opening or space formed by coiling the resilient stri or ribbon to form the conveyer; but any ot er suitable means may be provided for effecting this result, or the center of the conveyer may be left open. The outer secf tion of the auger and the outer end of the conveyer may pro'ect be ond the iexible shell or casing, as clearly s own in Fig. 1, to

venable them to operate more effectively on the material.

The exible tubular shell 15 is constructed of a spirally-coiled Wire or strip of resilient IOO IIO

i other suitable Waterproof material, to enthe casing 16,

able the apparatus to be employed for conveying water from a stream or other source ofsupply. The innerend of the flexible inclosing tubular shell of the conveyer extends into a combined fan and conveyer casing 16, composed of upper and lower tubular portions v17 and 18 and a connecting hollow portion or neck 19, forming a passage and provided at the bottom with air-inlet openings 20, located directly above the lower tubular portion. A fan 21 operates in the upper tubular portion of the casing and is rotated by a pulley 22, which is designed to be connected with a suitable motive power. The fan consists of a spirally-coiled sprin mounted on a shaft 26, journaled in

suitable bearings

27 and 28 of the upper portion of the fancasin The shaft 26, which forms a central core or the spirally-coiled sprin of the fan 21, extends beyond the outer en of the casing 16 to receive the said pulley 22. bearing 27 is formed in the outer end Wall of and the other bearing 28 coni, ssts of a perforatedlug or flange depending from the top of the casing 16, near the inner end thereof. The inner end of the casing 16 is provided with a hinged door 25, adapted to be swun upward to afford access to the interior. herotation of the fan creates a suction and carries the line dust into an enlarged annular portion 29 of the upper portion of the casing and through upper and lower openings 30 and 31', and it thereby serves as both a fan and a conveyer.

It will be seen that the combined digger and conveyer, which is designed for digging material from the earthl or from a pile or mass, 'is adapted to convey the lmaterial a distance from the point where the s ame is taken up andthat itis capable of being readily handled and of being quickly moved lthrough a mass of material It may be constructed of any desired diameter to adapt it for thel character of work to be performed and the kind of material to be handled.
