1 My invention relates to material receiving, storing and discharging apparatus, and more particularly to such apparatus particularly, but by no means exclusively, adapted to use with mineral vein-disintegrating and disintegrated materialdcliverlng apparatus which is capable of relative-- ly continuously delivery of material. Its various aspects will hereinafter appear.
Continuous minersfi'of a recently developed type clisint'egrate a mineral vein and deliver at their discharges the disintegrated inineral--as, for example,- but without limitation thereto, coal in such a manner that, while there" are brief interruptions between the delivery of the mineral resultiiig'irom the" disintegration of a given upright band and'the delivery of the min-- eral resulting from thedisintegration of the next adjacent band, and longer interruptionsthough still brief ones--hetween the completion of the disintegration of one transverse series of upright bands and the initiation of the attack on a suh sequent series, there is nevertheless a delivery of relatively-large quantitiesof mineral, with such minor interruptions of'continuity of discharge; that a sexious problem is presented by the fact that load reception is intermittent with the transport devices best adapted to handle the product of such Miners. discharge is possible, the problem is even more acute.
11, to present a simple example, we assume a Miner to have an average discharge rate" of a ton per minute, and a- Shuttle car can make a round, trip; including discharging time; from the; Miner discharge back to: the same again, in three minutes, it will be apparent that some provision for the storage of three tons, of coal must be made in order that the Miner can con tinue its attack on a mineral vein while the Shuttlecaf is traveling from the Miner to discharge point, ciiIecting-discharge of its load, and. returning to the Miner.
The wovision .or a suitable. storage device- When continuity of ada oted to meet such conditions is one oi. the
obj cts of my invention. Such a storage device mnst have provision for the discharge of its rethe "Miner the period of absence of the.
"Shuttle; car. This may be provided by the use of a hopper car, the use of a belt conveyor with stationary Sideboards, or by the use of a belt conveyor without side hoards, whei'i longitudinal dimension oi the device is not'a vitai 2 factor. One characteristic of any such device is, however, that so long as the conveyor continues to move (circulate-with the types mentioned) there will be spread over the top run thereof a layer of disintegrated mineral, thick or thin de-- pending on the rate of conveyor travel;v and, when a thin layer of material remains on the conveyor at the end otadischarge period, and the conveyor. ismnc'h slowed down to receive and distribute anew load; there-will necessarily have to he made some disposition of this thin layer; for otherwise it will be dumped on the mine bottom. It can, in accordance with my invention, be very satisfactorily gotten rid of b'ydelivering it to a Car which has been receiving a load; while preventin its renewal by cutting oil the access of new material to the conveyor and providing for its. temporary retention or storage while the conveyor is cleared. According'to a preferred embodiment of my invention there is provided means for temporarilyintercepting the discharge themthe Miner whilethe conveyor clears itself. Such a means may desirably be" arranged to enable the discharge of the temporarily held back material onto the" conveyor, andto be moved to a position in which the discharge of material from the- Miner shall have free access to the material-storage means; though in the event at a large mass-of material being stored, and the use of a narrow belt with side boards or a; Wider belt without side boards; a metering "function might be neededbe'icre theinterception was fully discontinued. The intercepting device may desir paratus soconstructed and arranged that the dis-- tribution of athin-"layer of material over the bottom: thereof during, the. final stages of unloading therefrom of an accumulated load may be prevented. Another object of the invention is to provide an improved material receiving, storing and discharging app-aratushaving in combination with itsmea-ns for distributing the-material re ceiveii thereby during loading thereof through-- out its length: at an appropriate rate and for onloadingthe material rapidly when it isde'siredto acsvgaee discharge it, of means for preventin material which may continue to be delivered to one end of the apparatus from being spread throughout its length during the final stages of unloading of "iid therefrom. A further object is to provice an improved material receiving, storing and discharging appa us having improved material handling and controlling apparatus associated therewith, whereby material may be moved from one portion thereof for discharge while material being delivered to another portion thereof be intercepted and stored where it falls, out of the field of operation of the material conveying means which forms a portion of such apparatus. Still another object of the invention is to provide an improved material receiving, storing and discharging apparatus embodying an improved combination of conveying and distributing means and temporary storage means for receiving and maintaining in a position in which it is not ongageable by the material conveying and distributin mean: a substantial quantity of material and for then dumping it on the material conveying and distributing means. A further object is to provide an improved. material intercepting apparatus. Other objects and advantages of the invention will hereinafter more fully appear.

The preferred embodiment of the invention is shown incorporated in an apparatus 1, which is quite similar in construction, except as hereinafter explained, to a Shuttle car. This construction includes a body 2 having a wide material-receiving portion 3 and having, in contrast to the rubber tired wheels of the usual Shuttle car, motor driven, tractor tread, supporting means 4, one at each side and each driven by a motor 5, one of said motors being shown in Fig. 2; and the propulsion of the apparatus 2 is controllable by any suitable mechanism, herein generally designated E, by which the tractor tread supporting means 4 can be independently or simultaneously driven. The apparatus i is adapted to move along behind a Continuous miner M, see Fig. 6, and to receive the disintegrated material which the latter discharges. This close adjacency may be maintained by the propulsion means of the apparatus. l or couldbe effected by the use of a suitable draw bar or equivalent connection between the Miner and the apparatus i. The Continuous miner M may be of various forms, but is shown for purposes of illustration as similar to the structure disclosed and claimed in the copending application of Samuel Leven, Serial No. 19,698, filed April 8, 1948, which applicati is owned by my assign-es. It includes a disintegrating apparatus '1, a driving motor aerator ii, suitable feeding, retracting, laterally positioning and vertically swinging meansnot all shown in this present case, but fully shown in the application above mentioned-and adapted to permit the Miner to attack and disintegrate the mineral vein in a plurality of upright sections of desired length or height, width and depth. The Miner has its own delivery conveyor 6 at the rear end thereof, and this conveyor is adapted to discharge to the apparatus I (see Fig. 6).
The apparatus 5 has conveyor 6 5, shown as a flight conveyor, and includng tights l2 moved flight-moving chains 23 driven by sprockets M on a transversely extending shaft 15, driven through worm and worm wheel mechanism [6 and a flexible connection it by a motor 18 through a clutch controlled reduction mechanism l9. Drive of the conveyor by the motor It may be controlled by a friction clutch as in the Charles Bali application, Serial No. 760,541, filed July 12, 1947, now abandoned, and owned by my assignec, or by any suitable switch mechanism, not shown.
The conveyor 3! extends throughout the bottom of the body 2, and through a vertically adjustable discharge section 2!, tiltable about an at 22 having the elevation of its discharge end 23 adjustable by a hydraulic jack device 24 supplied with hydraulic fluid under pressure from any suitable source, as, for example, the usual motor driven pump (not shown) customarily found on Shuttle cars, under the control of a valve device 26. The pump may for example be arranged and driven as in the Ball application above mentioned. The conveyor II is guided at its end remote from the shaft l5 as at 2?, and extends throughout the full length of the body l.
For the purpose of preventing access of material discharged by the delivery conveyor 9 to the conveyor ii, when it is desired that such delivery shall not take place, I have provided intercepting means shown in Figs. 1, 2, 3, 4, 5, 8 and 9. This includes a pair of material supporting plates, 35, 355, each secured to a longitudinally extending blocklike element 3? extending for the full length, longitudinally of the apparatus, of the plates 35 and E25, and each having secured to it a pair of horizontal bars or legs which, in the position or" the plates 35, 38 with their edges in substantial contact with each other, extend substantially for the full transverse width of the bottom portion of the body 2. The legs associatedwith the plate 35 are numbered 38, and those associated with the plate are numbered 39. These legs are guided in pairs in guide openlugs 21' of rectangular cross section, in openended boxlike elements ll arranged beneath the bottom plate d2 of the body 2. It will be evident that the legs 33, 3% guide the plates 35, 36 for movement rectilinearly towards and from each other. The plates extend through slots or openings 43 in the sloping side walls M of the body 2, and are adapted to be slid into contact with each other, as shown in Figs. 1 and 3, and into withdrawn position, asshown.-in liie: i. hit suit-. .e hydraulically controlled link, and lever mechani i5. Bearing blocks All supllorted on the. ie walls of the body 2 rotatably support tudineily extending shafts il carrying near e arms is to which there. is pivotally an eye: on a piston rod 5| ex.- r piston 52 recipro-cable, in a, cylly connectedat 5 to the body 2. the shafts All carryarms 55 rooted at 55 to links 57 which are Wally connected at 58 tothe block When the piss he 52 are at the of the cylinders. it will be evident hat :chanis s position the. plates i fi, idol to each other. When the pistons. 52 are,
moved outwardly relative to, the cylinders .53, the plates lit are drawn apart. as shownin c. Any suitable means, for supplying fluid to the cylinder and piston mechanisms for. controlling-the; positions of the plates 35. 36 may beprovided, as o r example, a source ofhydraulic fluid under pressure as above described, and. a control valve 55!.
The mode of operation of the invention, as so for described, may be understood most readily by reference to-Figs. l, 3, 4i, 6,; 7. 8 and 9;. ifhe hopper car is shown, in Fig. 1, as being empty, a eoioditipwh-ichmay be brought about at any time by interrupting the operation of the, Con tinuous with which the apparatus describedis associated, and continuing to circulate i w y-or i l. in this view, the plates 35,, 3%
t n contigu-ityto each other. Ordi-. with the hopper completely emptyh these,v will be withdrawn to the position shown in. =1, and loading of material into the car will be commenced. Then, when the Miner continueato deliver material into thehopper oar body 2, it will be allowed to fall to the bottom of the latter. and by appropriate manipulation of the controller tor-the conveyor driving motor H8, or preferablyof a clutch, the load will be distributed along the length of the body 2 until the body is fully loaded. Fig 7 represents diagram,- maticallythe loaded state of the apparatus. Both the body 2 and the discharge section 2 tare. loaded. According to oneexample,v perhaps three minutes may be requiredv to load'the body, In Fig. 8, the flight conveyor H has: been utilized todischaree all of the load, which has; been de posited on it and distributed throughout; its length. However, material has continued to, fall onto the body as the'load wasdischarged, sor a thinlayer or material, as shown. at Si, is spread over the bottom or the body. The operator will then cause the plates 355 and iii-i to be moved. together to the position of Figs 1. and 3, and Fig. 8. shows conditions just as the plates have been moved together and just as the discharged material from Miner begins toiallon the plates. The conveyor l i will be used to: dischargethe layer iii. to a Shuttle car or the like while the material continues to fall on the plates 35. and 35, with the resultv that acondition. as rep-- resented in Fig. 9 will be attained. When there is no material spread over the bottom of the body or .in the discharge section 2 l, the plates willbe separated, as shown in Fig. i. and the material will he dumpedv in the. body 2, the conveyor; being 1 first stopped or at least slowed down. Loading of the body will. then proceed.
It is. unnecessary to defer. the moving, 05. the; plates 35 and, 36 togetheruntil the main, load. has; been lolly; discharged and; a ;,thin- My r- 1115 iii material. extend thro ghout the: mulength; of

Bfizzand. 315., these may be advanced towards. each other and caused to intercept and store materiaL; lhis is" not, however, probably. the best way of procedure, and it is thought preferable tor-advance. the plates towards each. other only.
when the; condition.- of the. material in the: con.- veyor. approximates. that; of Fig. 8;.
Eteferringv to Fig. 6, it willbe seen that: the
discharge. conveyor 9. of the Miner-= is; deliver-.
