LOADING-MACHINE.

Specification ofLetters Patent. Patented Dec, 28, 1909. Application filed December 31, 1908. Serial No. 470,234.

Homins'rno, a subject of the King of England, residing at Quinnimont, in the county of Fayette and State of Vest V1rg1n1a, have invented new and useful Improvements in lioading ltlachines of I which the following is a specification. r

This invention relates to a loading machine or apparatus for use with loose material and particularly adapted to transfer coal from a pile, bin, or other place of storage to a car or cars and having an automatic operation to facilitatevthe elevation or disposition of coal" or other loose material in a carrying or transporting means at'a mini mized expense by dispensing with and obviating the usual manual methods.

The improved machine or apparatus 1s, portable and may be readily moved. fromv one place to another without confinement to any particular form of track means and may be conveniently arranged in operative relation to a pile of loose material or coal and a car or other receptacle to be loaded 7 without reql'iiring the car or receptacle to be disposed in a precise position relatively to the material to be loaded thereinto.

The machine or apparatus also includes a motive means and cooperating mechanism whereby it may be readily'moved over the ground surface to an operative positionand either forwardly toward and partially in engagement with the loose material or coal to be loaded or backwardly from the latter as conditions and change of position may require, or the machine may be permitted through the operation of the mechanism to remain in a fixed position while loading the loose material .or coal. I

It is preferred that the machine or apparatus embody in its organization motive means and cooperative propulsive mechanism, but the portability of the machine is not confined to the use of any particular operating mechanism, the essential character stics in this respect being the ready movability of the machine from one place or position to another without the use of a track means. i

A further essential feature of the present machine is a conveying means adjustable upwardly and downwardly and in opposite lateral directions without in the least modifying the effectiveness of "the actuating mechanism or affecting the operationof the feeding means at the receptive extremity of the machine. I

Other structural advantages will be hereinafter more fully specified, and a preferred form of the improvements is illustrated in the accompanying drawings for the purpose of demonstrating a practical application of the same, but itwill be understood that the invention is n0t limited or confine'dtothe precise construction which will be hereinafter veXpIainedand particularly to the actuating mechanismand motive means or to any particular form of motive means and cooperative mechanism geared thereto.

In the, drawings: Figure 1 is'a perspective view of a loading machine or apparatus embodying the features of the invention and shown applied in operative position- Fig. 2 is-a top pla'n'view of a portion of the machine or apparatus and articularly showing the receiving frame an feeding meansan movable, deflector and a portion of the ,con-

veyer or conveying means in operative associat on with the feeding means. F1g..3.1s a side elevation of the mechanlsm as. shown by Fig. 2. Fig. 4 illustrates ahoriz ontal section taken through a portion of the mechanism shown by Fig. 3. Fig. 5 is a top plan VIEW of thereceivmg frame and a portion of the actuating mechanism and illustrating the feedin means and motive means removed. Fig. 6 is a longitudinal vertical section of the mechanism as shown by Fig. 2.; Fig. 7 is a detail plan view of the upper extremity of the conveying means.

. The present machine or apparatus embodies many features of improvement of the apparatus or loading device disclosed by my Patent No. 839,997, dated January 1, 1907. In this patent the machine. is confined to operation on a, fixed track means, and. the feeding means, consisting of a revoluble platform, wheel or plate, delivers the loose material into a conveying means having a fixed position, and from this conveying means the coal into cars, but the machine embodying the present features of invention has a greater scope andusefulness in the particulars which will ,be hereinafter explained.

g I plyingconnecting shafting or gearing. vmachine s in fixed posltionbr'has been Arranged tgover and 1 extending partially across the feeding triednaconsisting of the plat-form, vwheel or plate 4, is a movable de- 1 flector in the form ofanendle'ss belt 36 hav- 11. mg lags, buckets, or analogous dev cesriij and movable toward the rearlof themachine fi'oin'the support ,8, the, said shaft 21 being parallel-with the support :8 and having on 1 its outer and inner extremities suitable bevel l gea'rs28 anrlQ-t anddriving the shaft 191;

l I l tinual mesh with a pinionv 27 on the inner end of avmotor d riven shaft QS having on its outer extremitya sprocket wheel29. The i or in such direction as to cause' the loose material, such as coal, brought around I against the said. deflector by the feeding 0 means, or revolnble "platform 4 m begdelivered from therear portion ofthelatter. The pa'rtfof themovable deflector whichfis v 1 engagedby the loose material isbraced or g I held in positive working position by a fixed I253 mesh, and the shaft 21is actuated through i t i t l tions of tlie movable defleetoriiasg s partition 38, an(lain terpjosedbetweenv he porown by Fig; 4; A suitable spool or sleevc" 39.1%: fitted f over the upwardly projecting portion, of the" jpost 31*andconstitute's-a roll'eroven which, 9 5

44 provided with a pinion at?) at its forward extremity held in continual mesh with the pinon 23 on the outer end of the power transmitting shaft 21.

Cooperating with the rear portion of the feeding means is a delivery conveying means 46 which is adjustable upwardly and down- I wardly and in opposite lateral directions and the conveying belt or analogous movable element 4? thereof is actuated to have a rearward movement toward the outlet extremity t8 of said conveying means by a roller 49 at c said extremity and which is actuated by a shaft 50 extending along the side of the conveying means and provided with a bevel i pinion 51 meshing with a similar pinion 52 on one extremity of the spindle or shaft of the roller 49. The shaft 50 is practically a continuation of the shaft 44, a flexible connection 53 being interposed between the two shafts 44 and 50 and may be of any preferred type, this flexible connection as shown being in the form of a suitable length of flexible shafting. This flexible connection between the shafts 44 and 50 compensates for the adjustment of the delivery conveying means.

From the foregoing description and as hereinhefore noted it will be observed that all of the movable parts are controlled as to their actuation from the motive means 3; and the several elements specified are disposed at an angle relatively to the inclination' of the feeding m nus and the several parts of the frame 4 and particularly the plate 5 coi'ipeating with the said feeding means or supporting the latter. This mechanism presents a very effective actuating organization. but it is obvious that it may 'be modified. and that the invention is not confined to the precise elements hereinbe forc particularly described.

The roller 3%) not only serves as an engaging means for the movable deflector or convcyer E .but prevents dust and grit from clogging the bearing for said roller orv the post 31. As an incidental protective feature a portion of the movable deflector or. conveycr an. the motive means and the mechanism below are covered by a dust hood or housing .34 of the shape shown particularly by Figs 1. 2 and 3 and applied in such manner as to avoid the least interference with the operation of the movable deflector or conveyer. This hood or housings'il is open at its outer portion to give access to the motive mean rear of the movable deflector or conveyer and supported by the frame 1 is a rigid extension 55. and hinged thereto and also to the rear end of the flared side 3 are guards M3 and 57 which movably project into the conveying means 46 between the sides of the latter. and cooperating with the lower portions of these guards are elongated upstanding flanges or shields 58. The lower end of the conveying means projects under the rear extremity of the frame 1 far enough for the feeding means or revolublc platform "f to permit the latter to effectively deposit the loose material on the belt or analogous device f7 and is fulcrumcd as at 59 on the base of the frame 1 or on the center of the rear cross bar 7 oftlie said base, the fulcrum means being preferably in the form of a ball and socket joint as shown, by Fig. (3, to permitthe delivery conveying means 46 to be raised or lowered and adjusted laterally in opposite directions at any angle desired with respect to the car or receptacle to be loaded and the most effective position of the feeding means embodying the revoluble platform. wheel or plate -'t relatively to the loose material into which the receptive or front extremity 2 of the frame 1 may be projected. In the adjustmentof thc conveying means it; no openings will be formed between the rear portion of the feeding means and the said conveying means owing to the fact that the guards at and 57 will slide longitudinally into or outwardly from the portions with which they engage and also move away from and toward the bottom of the conveying means without producing a gap owing to the flanges or shields 58 and the overlap of the sides of the conveying means by the said guards 56 and 57. this means the loose material discharged from the revoluble platform, wheel or plate 4 will with certainty be deposited upon the belt or analogous conveyingmeans 47 irrespective of the adjustment of the said conveying means or the position of the feeding means relatively to the delivery conveying means it The outlet extremity 48 of the conveying means it; is positively supported in accordance with the elevation of said extremity by hinged legs (it) which may be turned or shifted at any angle found neccs sary under the conveying means and held in fixed position by braces (31 movably attached to the sides of the, conveying means and formed with a plurality of openings o2 adapted to register with a single opening 3 in each of the legs, the openings 2 and or, having pins 64 removably titted therein.

This prop means for the outlet extremity of the conveying means is a very simple mode of holding the said extremity of the convcying means vat the elc'ation desired. but it will be understood that any other means and cooperating mechanism. Directly in 1 maybe substituted therefor and in some mstances a prop means may be unnecessary as the outlet extremity of the conveying means could be supported on the. sideof the air or other receptacle.

The operation of the machine will be readily understood from the foregoing de scription, butto briefly summarize the same, maybe stated that the receptive extrenr ity of theframe 1 is caused to penetrate or be located in feeding proximity to a pile of coal or other loose material, and the con veying means 46 will'be shifted or adjusted eitherupwardly, downwardly, or laterally as may-be required to place it in the most effective position relatively to the car or receptacle to be loaded. The feeding means consisting of therevoluble platform, wheel or plate 4 is then set in motion and the loose material deposited thereon through the receptive extremity of the frame is carried around and upwardly adjacent to the flaring side 3 and brought into contact with the movable deflector or conveyer .36 which forces the loose material rearwardly into the delivery conveying means between the guards 56 and 57, and by the said delivery l conveying means the loose material is'finally deposited in the car or receptacle. An effective incidental feature of construction consists inroughening the upper surface of.

the revoluble platform, wheel orplate 4 or in providing the latter with, projecting means to set up an adherence of the loose material or coal with the upper surface of the said revoluble'platform, and in'the present instance this rougheningmeans is shown in the form of rivet or bolt heads 65 arranged in curved lines and having a clearance with relation to the fixed partition 38 by the formation of openin s 66 in the lower edge of said partition. t is to be understood, however, that, any meansjma'y be employed -for'rougheningthe upper surface of the platform 4 and the invention is not limited in the useof the precise means as shown and "described. At any time during the loading means cooperating with the frame and pro-' vided with means for rendering the same movable upwardly and downwardly and laterally in opposite directions independently of movement ofsaid feeding means.
