Application filed May 20, T 0 all whom-t may concern.' Be it known that l, CHARLES E. Davis, a citizen of the United States, residing at Chicago, in the county of Cook and State of illinois, haveV invented an Apparatus for ltlandling Ure, of which the following is a specification. This invention relates to improvements in apparatus for handling ore and the like and has for its principal object to provide a simple and durable conveying apparatus which may be economically operated for transporting loose material from one place to another, and a new method of operating the same. My invention may best be understood by reference to the accompanying drawings, in which Figure l is a plan view of my apparatus in one working position in a mine. Figure 2 is a view of my apparatus in another position. Figure 3 is a view of the same apparatus in a third position. lligure l is an enlarged view of the apparatus in elevation. ln the embodiment of my invention illustrated herewith, my apparatus is shown as used in mining operations in which loose material is to be transported from the Working face, or place from which the material is being mined, to a suitable loading chute. ln Figure l, the working face is indicated at A, at a point removed from a loading chute B, which may be of any usual arrangement, or construction. rlhe ore, or similar material, is broken down from the working face A and deposited on the floor of the mine, and in loose condition suitable for removal to the loading chute B. My . loading apparatus comprises a conveyor device, such as a scraper, or scoop 1, and a guiding frame 2. The scraper l is preferably bottomless, and has one side l thereof curved so as to conform substantially With the curved forward end 2a of the guiding frame 2, Said guiding frame is provided with a pair of rearwardly extending beams 4, a having a slot 5 therebetween. The forward portion A of the guiding frame is preferably provided with a plurality of rollers 3, 3, and forms a guiding and bearing surface for the scraper l. The frame 2 is adapted to be held in place by means of a guiding device, such as a pair of jacks 6, 6a, 1920. Serial No. 382,636. of the usual type, adapted tobe inserted in the slot 5. rlhe jaclrs 6 and 68 are spaced apart so as to .guide the movement of the frame in a longitudinal direction. Movement of the frame is preferably accomplished by means of a draft device which may comprise a iexible cable 7, adapted to be fined at a forward end to some suitable anchor, as for instance, the forward jack fr?, and operated by means of a ratchet device comprising a drum 8, a pair of ratchet wheels 8b and 8c, an operating lever 8d for operating the ratchet Wheel 8b, and a paWl 86 for engaging the ratchet wheel 8c. lt will be seen that the paivl 8@ serves to retainthe drum 8a stationary While the handle 86 is being manipulated to Wind up the cable 7. lt, will be understood however, that any equivalent means may be provided for moving the guiding frame forwardly with respect to the fixed guiding jacks 6 or 6, as the loading operation proceeds. lt will be observed by reference to Fignres l, 2 and o, that the guiding apparatus may be directed at varying angles toward the material to be loaded, b-y suitable arrangement of the guiding devices 6 and 6a. When directed at an angle, however, such as shown in Figure l, a suitable bracket 9 is attached to the rear end of the longitudinal beams a, 4, as shown. This bracket preferably carries a plurality of rollers 10, l0, similar in construction to rollers 3, 3, before described in connection with the curved end 2a of the forward end of the frame 2. The scoop l is operated by means of suitable draft ropes comprising a head rope 11 and a tail rope 12. rlhe curved inner side la is preferably longer than the opposite side 1b of the scraper so that the former side eX- tends forwardly beyond the upright for-V Ward margin 1 which forms the cutting edge of the scraper as it is gathering its load. The head rope is attached at or near the forward end of the inner side la and the tail rope l2 is attached to the rear of the scraper and preferably to one side of the longitudinal axis thereof, as shown. The draft ropes may be operated by any suitable mechanism, such as hoisting engine .0, positioned beyond the loading chute B so as to draw the scraper l to the said chute to be unloaded. l also provide a sheave 13 on the rear end of the apparatus opposite the bracket 9 for kai the purposelof guiding the tail rope 12. It Awill be observed, however, that the bracket 9 and the sheave 13 are interchangeable, and that the scoop and draft ropes are adapted to move in either direction about. the guiding frame. 1. rIhis arrangement allowsthe apparatus to be directed either to the right o: to the left, so as to completely remove material from spaces of varying widths, as desired. In order to render my apparatus easily portable, I provide means for detachably separating the apparatus into a plurality of sections, which means may comprise overlapping end members 14, 14 and 15, 15, on opposite ends of the beams 4, which members are connected together by any suitable means such as bolts 16, 16. Where it is necessary to deflect the draft ropes and to change the path of movement lof the scraper, I provide a guide member 17, adapted t0 be fixed by a jack in the usual manner. rIhis guide member comprises an arcuate frame portion 18, and carries suitable rollers 19,19, forming a curved bearing surface conformingr substantially with the curved side 1a of the scraper, so that thecourse of the draft ropes and the scraper may be deflected, as shcwnm Flgure 3. The'use and operation of the apparatus above described 1s as follows: The guiding frame 2 is positioned adjacent the pile of material to be removed or transported, and the draft ropes are connected with a winding engine suitably located t0 move the scraper toward the loading chute, or place where the material is to be unloaded. The scraper is pulled rearwardly by the tail rope 12 about the guiding frame until the open end of the scraper faces the pile of material, as shown in Fig. 3. rIhe movement of the scraper is then reversed by releasing the tail rope 12 and pulling the drag rope 11. The scraper is loaded as it moves forwardly about the curved end of the frame 2, the arrangement being such that the scraper has a considerable lateral bearing on the frame, and the cutting edge 1c is directed into the pile of loose materlal to gather the load as the scraper is swept around the frame. The scraper is moved to the-chute B and unloaded and is again returned to its initial position ready to collect another load. When sufficient material within reach of the scraper has been collected, the frame 2 is moved forward by means of the draft device 7 and ratchet 8 or its equivalent, to advance the scraper toward the pile. The head frame 2 may be moved into various positions and angles with respect to the material to be removed by fixing the guiding means as desired. In the event that it is desired to change the course of direction of the scraper when moving from the head frame to the loading aaeaeea chute, the auxiliary frame 17 is fixed in the position desired as shown. It will be understood that my apparatus may be constructed with details diering greatly from the construction illustrated and described herein Without departing from the spirit and scope of my invention. I do not therefore wish to be limited to the form of apparatus herein shown and described excepting in so far as specifically limited in the appended claims.
