4 Claims.
This invention relates to a gathering organization for loading machines, this application being a division taken from my co-pending application Serial No. 668,046, filed April 25, 1933.
The object of this invention is, to provide a gathering organization of improved efficiency especially in the respect that it will have a minimum of shattering effect upon the coal in its actuation of same from the floor of the mine onto the gathering elevator whereby it is conveyed away from the point at which the coal is mined; another object is to provide a gathering organization which will cause the coal to be retained upon the conveyor flight at the gathering end of the machine, instead of overflowing laterally therefrom back onto the mine floor, a fault which is common to many of the gathering organizations heretofore in use.
My improved construction is clearly illustrated in the accompanying drawing in which: Fig. 1 is a plan View of the lower end of a gathering and elevating conveyor of a loading machine, the general use of which is the gathering and elevating of coal from the mine floor and the transfer of same to a mine car or another conveyor.
Fig. 2 is a section of Fig. 1 upon the line II-II as if the section were taken on line II-II.
Fig. 3 is an outside, side elevation of the gathering arm, the disc which operates the same and the adjacent portion of the deck-plate of the frame.
The construction shown in said drawing is substantially as follows:
The portion of the gathering and elevating conveyor 1 which is usually termed the shoe, operates either in close proximity to or in contact with the floor of the mine, adjacent to the coal to be operated upon; the remainder of the elevating conveyor, which extends upwardly from the mine floor comprises a frame work consisting of an elevator channel 2 and the deck plates 3, 3; positioned at a point intermediate said shoe and the lower end of said deck plates, are two revoluble discs 4, 4, one at each side of said channel 2, said discs 4: are each driven by means of a bevel gear 5 and an intermeshing pinion 6, which pinion is rigidly mounted upon a revoluble foot-shaft 7, which shaft is, in turn, revolved by the conveyor chain or apron which travels within said channel 2.
Each of said discs is provided with a perpendicularly-extending crank pin 8 adapted for the actuation of a gathering arm 9, each of which arms is provided, in proximity to its lower this application July 27,
end with a crank-pin bearing 10 and its opposite upper end with a bearing 11 for the reception of a pin 12 which is carried by the free end of an oscillating delineator-lever '13 whereby the shape and extent of an assumed diagram, as 14, is delineated by the point of an implement 15 which is carried by said gathering arm; said diagram indicates the area swept by said implement 15 from which area material is gathered and actuated onto the conveyor flight; the pivotal end of said lever 13 is carried by a bracket 16 which is aflixed to one of the structural elements 17 of the conveyor frame, and, as shown in the drawing, said bracket 17 is located beneath the deck-plate 3 upon its respective side of the frame of the elevator.
Said gathering arm 9 is provided upon its inner side or face adjacent the channel 2 with a broad flange 19, the inner face of which extends substantially perpendicularly to the upper adjacent face of the adjacent deck-plate 3; the lower edge of said flange being arranged in close proximity to said deck face, whereby it is adapted to perform the two important functions of preventing coal or other material which may overflow from channel 2, from falling from the conveyor and also to actuate such overflowing coal back into the conveyor channel onto the conveyor belt or chain, as the case may be.
It will now be readily noted that, as a disc 4 revolves it imparts a circular line of travel to the gathering arm bearing 10 and to the adjacent portion of said arm and that this motion will cause the upper end of said arm to travel along the arc defined by the dotted line 18 and also to have a laterally vibrating movement, whereby any material which may overflow from the conveyor channel onto the deck 2 will be actuated back into said channel; this vibrating movement is uniform throughout its extent and furthermore it is such as to exert no shattering effect upon lumps of coal with which it comes into contact, and because of this, it is free from the degrading effect upon coal that is produced by other types of gathering arms.
I claim the following:
1. In a gathering organization for loading machines, a conveyor frame, a conveyor carried by and operative in said frame, a deck plate positioned laterally of said conveyor, a rotatable disc adjacent the receiving end of said conveyor, with its upper face flush with said plate, a crank pin carried by said disc, a gathering arm operably connected adjacent one of its ends to said pin with its lower face in close proximity to the adjacent face of said disc, and a delineator arm connected at one of its ends to the other end of said arm, the other end of said delineator arm extending beneath said plate and connected to a pivotal point thereunder.
2. In a gathering organization for loading machines, a conveyor frame, a conveyor flight carried by and operable in said frame, deck plates positioned laterally of said conveyor, rotatable discs positioned laterally of said conveyor adjacent the receiving end thereof, a crank pin carried by each of said discs, a gathering arm operably connected adjacent one of its ends to each of said discs and a delineator arm for each of said gathering arms, said delineator arms being positioned beneath said deck plates with one end of each thereof connected to its respective gathering arm and its other end connected to said frame.
3. In a gathering organization for loading machines, a conveyor frame, a conveyor flight carried by and operable in said frame a deck-plate positioned laterally of said conveyor, a rotatable disc adjacent the receiving end of said conveyor with its upper face flush With the upper face of said plate, a crank pin carried by said disc, a gathering arm operably connected adjacent one of its ends to said pin with its lower face positioned in close proximity to the adjacent faces and said plate, the innerface of said gathering arm being provided with a flange extending perpendicularly to said disc and deck faces and a delineator arm connected at one of its ends to the other end of said gathering arm, extending beneath said deck plate and oscillatively attached to said frame thereunder.
4. A gathering organization for loading machines comprising in combination, a conveyor frame having a conveyor therein and a laterallyextending deck plate at each side of, adjacent the lower end of said frame and conveyor, a gathering arm carried by each side of said frame operable over said deck plates respectively, one end of each ofsaid arms being arranged to actuate material onto the lower end of said conveyor, and the other end thereof to replace material onto said conveyor which has become displaced from said conveyor onto said plates, each of said arms being provided upon its inner face with a perpendicularly disposed flange of equal height throughout the linear extent of said arm, a de lineator arm for each of and attached at one of its ends to the upper end of its respective gathering arm, the other end of said delineator arm extending beneath its respective deck plate and attached to said frame therebeneath, and driving means imparting to said conveyor and to said arms their necessary mode of operation.
