This invention relates to improvements in loader shakers. v

`It is an object of the invention to provide a structure for conveying material in bulk g5 form into the interior of a box-car and to avoid excessivebreakage of the material during its transfer to a conveyor located inside of the car. Y

It is also an obj ect of the invention to pro-A vide in a structure of this type means for im* parting to the material while it is being transferred a shaking movement for gradually ad vvancing the same towards the inside of the car.

i VAnother object of the invention is to pro-V vide a shaker in which the movement of its contents is irregular or intermittently inl creased and decreased in speed during its transfer to the interior of the car.

The invention also'has the object of providing a structure of this type which can readily be placed in diiferent positions either in or outside of a car without requiring a de!` tachment of power actuating means through to a special shaking member.

VAnother object of the invention is to support the shaking member in a feeder trough which is arranged to be readily movable to dierent locations whil-e located either in or outside of the car.

lVith these and numerous other objects in view an embodiment of the invention isillustra-ted in the accompanying drawings and is described in the following specification in which reference is made to the drawings.

Fig. l0 is a `transverse section on line 10-10 of- Fig. 3 showing the shaker and shaker screen mounted on the feeder structure.

On a foundation 1 a post 2 isrmounted which carries at a suitable height pivotally an Outrigger or arm 3 to the free end of which another arm 4 is pivotally secured, whereby through the variable angular relation of the two arms to each other and relatively to the post 2, the entire shaker structure 5 may be swung to assumethe necessary positionv for its introduction through a relatively narrow door into the interior of a boxV car 6 and still leavev suihcient clearance between it and the top of the car ,door opening to permit large lumpsof coal to pass. By again varying the relative `position of the supporting arms 3 and 4, the structure 5 may also be shifted in the carto a position to deposit the material delivered to the conveyor 7 to the desired points in the interior of the car. The conveyor 7 itself also is movably supported, as shown rin Fig. 2, upon articulated arms 7a and 7b to be introduced into Vthe car 6, or to be moved from thev same, an operative position of the conveyor being shown infull lines, and an inoperative position in dotted lines in Fig. 2. Its detail construction is fnot of importanceA in this application. Y

. The'arrangement of the supporting arms 3 and 4 does. not form the subject matter of thepresentinvention, and their details are not described at length herein; reference may be had forthis purpose to the United States Patent No. 988,67 4 ofApril 4th, 1911 granted to F. Ticknor and George Manierre on improvements in loading machines, as well as to other `of my copending applications. p

As shown in Fig. 2, the loader .structure 5 is illustrated in full lines showing it introduced through the side door of the car 6, vwith the conveyor 7 shown lextending at substantially right angle to the same. The dotted lines, Fig. 2, show the loader structure withdrawn, located at a relatively great distance from the side of the car and on the outside thereof. The entire system of the combined loader and drag conveyor 7 is extremely flexible and permits the operatei` a wide range from which to select the various positions in the interior of the car to which the material carried by the drag or other conveyor is to be discharged.

The aims 3 and 4 are illustrated in Fig. 3 as being built up of rolled shapes, but it is obvious that instead of this construction, other forms may be used such as castings. The inner arm 4 carries at its free end a bracket supporting a bearing 9 in which the lower end of a journal pin 10 is secured. The upper end of this journal pin is liXedly connected with a bifurcated yoke 11 of considerable width. The two arms 12 of this yoke terminate in bored bearing bosses through which a shaft 13 extends rotatably. It is obvious, therefore, that this yoke 11 may be turned about the axis of the journal pin 10 and that the parts supported by the shaft 13 also may be rocked vertically. A spring 10--A having its lower end secured to the journal pin 10 and connected at its other end to the angles 22 serves to maintain the entire feeder structure in a balanced position.

The shaft 13 serves for carrying a feeder structure, the details of which are illustrated in Figures 4, 6, 7 and 10. rl`his feeder structure comprises two relatively narrow lateral walls 15 and 15a iixedly associated with slanting plates 16, the lower ends of which are connected by a platform 17 extending parallel to the rock shaft 13. Corner posts 18 are secured to the rear corners of platform 17, and their upper ends are connected by gusset plates and rivets with angle irons 19 which extend substantially forward from the upper ends of said corner posts 18, and the forward ends of which are slightly deflected to produce a cainber, the forward ends of the angle 19 being somewhat raised relatively to the rear ends. The-vertical legs of the angles 19 are riveted to the walls 15 and 15a. The front portions of the lateral walls 15 and 15a are united by a transverse plate 20, which is centrally depressed or slightly curved transversely to the length of the structure. Another Spanner-plate 21 extends crosswise of the walls 15 and 15a between their front and rear ends, this Spanner plate being also secured to the tops of the slanting plates 16, connected with the platform 17. As a further means of strengthening this open bottom trough structure and safe-guarding it against distortion, a pair of angle irons 22 arranged and spaced back to back extend longitudinally from the front transverse plate to the spanner plate 21, the ends of these angles 22 being secured to said

transverse plates

20 and 21. At the rear end of the skeleton frame or trough a vertical plate 23 extends between the lateral walls 15 and 15a of the structure and is secured to these lateral walls by means of angles riveted thereto, or in any other suitable way.

A delivery chute 8 is provided for conveying material into the feeder structure. For preventing the material from flowing over the opposite wall while being charged from one side, a sheet metal plate 24 is connected with one of the lateral walls of the structure, as shown in Fig. 4. rllhe plate is secured to thc inner surface of one wall 15, the upper portion of this plate being slightly deflected towards the interior of the trough-like feeder, and this wall is connected at its end with a curved back plate 25 extending crosswise between the walls 15 and 15a and being bent on one end to merge into an inclined delivery apron 26, secured to the wall 15a of the 'trough-like structure. This apron projects outward from thsaid wall to a considerable extent and directs the material dropping from the conveyor or loading chute 8, Figs. 1 and 2, over the apron 26 into a shaker 32 which is inovably disposed within the trough-like structure. rlhe extension plate 24 of the chute is secured to the outer face of the lateral wall 15 of the trough structure by one or more brackets 28 said brackets being offset midway of their height to project inward above the upper edge of the wall 15. The plate 24 is then fastened in any suitable way to the offset portions of the brackets 28 so as to provide an interspace 29 between the lateral wall 15 and the plate 24 ofthe chute. YVhile thcbrackets 23 are mounted on the outside of the wall 15 for supporting the plate 24 of the chute in the interior of the trough structure, the wall 15a, as will be seen from Fig. 7 is reduced in height over a portion of its length, as indicated. at 30, and is provided with an angular reinforcement 31 to which the apron 2G is secured.

For the purpose of maintaining the shaker trough or screen 32 movably supported in the interior of the feeder structure, the lateral walls 15 and 150. of the latter are provided near the rear and front ends with brackets 33, having an intermediate portion spaced from the lateral wall 15. These portions serve for receiving pins 34 which are held against rotation. as shown in Fig. 9, the inner ends of these pins entering the flanges of the angle bars at the corners of the feeder structure. The pins 34 serve for supportingy struts or links 35. the heads of which are constructed as bearings for'receivingthe pintlcs 43 from which the shaker is supported.

The shaker, as illustrated in Fig. 5, is formed of lateral walls 37 and a bottom That wall 37 of the shaker which. is movable in the interspace 29, has an upper straight edge, while the opposite wall has a relativelyv long cut-out portion 39 confined at its ends by slanting edge portions to accommodate the slanting apron 26 of the delivery chute. The walls 37 of the shakerv are secured at their lower edges yto legs of angles 40, the forward portions of which are slightly deflected up ward relatively to the rear portions, and to these angle bars there is secured the bottom plate 38, the front portion of which, therefore, also slants upward relatively to the rear portion, so that the front edge of the shaker lies on a higher level than the rear edge of the same, and furthermore, this front part is slightly curved transversely, corresponding to the curvature of the front spanv ner plate 2l of the feeder structure. Owing to this deflection of the shaker bottom the acceleration which the material might gain while traveling over the same is effectively prevented.

For the purpose of movabl'y connecting the shaker 32 with the feeder structure, straps 4l and 42 extend from the shaker near the front and rear ends ofthe same, the front strap 42 preferably extending underneath the bottom plate 38 of the shaker. They project above the walls 37, the projection being deflected outward and downward to provide a` space in which the heads of` the struts or links may enter and adapted to receive the pintles 43 passing through the straps and also through the heads of the links 35.

i The shaker bottom 38 is provided with a large number of perforations :44 extending over a portion of its front area, whereby grit and other particles of a size not large enough to warrant the loading of the same, `maybe discharged while traversing said bottom so as to prevent its reaching the interior of the box car.

A bracket 45 is secured to the outer surface of the bottom of the shaker,vthis bracket formin a bearing for a transverse pin 46 to which a link 47 is pivotally connected. The opposite end of the link 47 is movably secured to the free end of a bell crank 48 which is pivoted to a bracket 49 mounted on the slanting wall 50 which connects the plates 16 secured to the feeder structure. While one arm of this bell crank lever is connected by means of the link 47 with the shaker pan 32, the other arm of this lever is pivotally attached to a. crank 5l which is movably secur-ed` to a wrist pin 52 eccentrically mounted on a uniformly rotated gear wheel 53 supported on a countershaft 54 which rests in bearings on the platform 17. The uniform ret-ary motion is imparted to the gear 53 from a motor 55 which is also carried on the platform and tie shaft of which mounts a pinion 14 in engagement with the gear 53.

Upon rotation of the gear 53. set up by the operation of the motor, the wrist pin 52 will revolve and the crank 51 extending from the same will alter continually its angular relationto the radius extending from the center of the gear to` the crank pin. A peculiar oscillating movement will thereby be imparted to' the `bell crank '48, the rate of movement j of thebell crankbe'ing greater when the crank pin travels through the approximately verticalfpertions of itsfpathv than upon travel thru the approximately horizontal portions of its path, or the uniform movement of the crank pin varies the rate of movement of the bell crank. The result of this peculiar movement in which the speed of the bell crank lever varies in each complete revolution of the crank pin is that the shaker pan 32 suspended from the links 35 which are pivotally mounted on the trough structure is imparted a jerking movement over a certain portion of its path and a relatively smooth or quiet reciprocating movement in other portions of its path.

The material deposited over the slanting apron 26 and in the shaker will, therefore, travel onth'e shaker pan in irregular reciprocating movements towards the outlet or front end of the pan from where it will be dropped into the drag conveyor 7 which may be inserted Vinto the 'interior of the box car to any desired position. j

in prior loaders of this type the coal taken from a mine conveyor to the loader could not be transferred withoutk considerable breakage; particularly gravity chutes had been used and had becomea most prolific source of breakage. Owingl to the novel oscillating back and forth movement of the shaker form-.

ing a principal part of the present device, the travel of the coal is intermittently retarded and advanced, and owing to this alternate retardatfion andrincrease in the speed of delivery, the enormous breakage with which the trade had to figure in devices of this kind is entirely eliminated.
