COAL-CLEANER.
To all whom it may concern Be it known that I, JAMES R. MONT- GOMERY, a citizen of the United States, residing at Frankfort, in the county of Mar- State of Kansas, have invented certain new and useful Improvements in Coal-Cleaners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in coal cleaning apparatus.
The object of the invention is to-provide a portable coal screening apparatus especially designed for the use of local coal dealers for screening out coal before sending it to a customer so as to deliver it in a clean condition free from dust.
Another object of the invention is to pro-- vide simple and efiicient apparatus of this character by means of which coal may be simultaneously screened and loaded from a bin into a vehicle.
Another object is to provide an apparatus of this character so constructed as to protect the operator and surrounding atmosphere from the dust produced by the screening operation.
With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and claimed.
In the accompanying drawings: Figure 1 is a longitudinal vertical section thereof; Fig. 2 is a transverse section, and Fig. 3 is an end elevation thereof.
In the embodiment illustrated, a suitably constructed truck 1 is shown on which is mounted a closed casing 2 preferably composed of heavy galvanized iron and of any suitable or desired size. When possible, the power for operating the screening apparatus is to be furnished by a motor 3 mounted on the truck and which may be electric or of any other desired construction provided that -it be as light as possible as the apparatus is designed to be moved from one coal bin to another as required.
Extending downwardly at an oblique angle from the upper end of the casing 2 is a conveyer 4 inclosed in a casing and similar to those used on corn shellers. This conveyer casing is preferably made in foldable sections 5 and 6 and the free end of the Specification of Letters Patent.
Application filed May 25, 1914. Serial No. 840,807.
by an endless belt 14 Patented May 25, was.
outer section 6 into a bin and is provided with a hopper 7 to receive the coal to be screened. The free end of this conveyer casing section 6 is preferably supported by adjustably mounted uprights 8 here shown slotted longitudinally at 9 and engaged with the walls of the conveyer chute or casing by means of set screws 10 whereby saidsupports may be adjusted to adapt the device to coal bins of different heights. When the section 6 is folded on the section 5 these uprights are turned up and form a support for engaging the fixed member 5 of the conveyer casing and form a support therefor. This conveyer 4c is shown mounted in the closed casing and comprises an endless belt, the stretches thereof being adjustable by means of a screw 11 to provide for the tightening or loosening thereof as may be desired, the conveyer being loosened when the sections of the casing thereof are to be folded.
A small opening 12 is provided at the loWer end of the conveyer casing section 6 for letting out any dust or small pieces of coal which might hang pass downward. This conveyer casing is preferably provided with a partition 13 on which the upper stretch of the conveyer is designed to travel. This conveyer is driven connected with the motor 3 and shown clearly in Fig. 1, and is adapted to conduct the coal thrown into the hopper 7 upward and. discharge it into the upper end of the casing 2 onto a suitably disposed screen 15 which is arranged at an inclination being inclined downwardly from the end on which the coal is discharged to a discharge pipe 16 arranged at the opposite side of the casing 2. This pipe or chute 16 is placed in position to adapt it to extend over the body of an ordinary coal Wagon or cart. The screen 15 is preferably constructed with a frame made removable to adapt it to be interchanged for a screen of different mesh when desired.
is designed to extend back to the chains as they Arranged over the spout 16 is an outare spaced apart as shown at and at one end thereof is arranged a fan 21. At the opposite end of these members in alinement with the fan 21 is an upwardly extending dust discharging pi e 22 provided at its free end with an ad]ustable hood 23 which may beregulated tov discharge the dust at any desired angle. y
A door 24 is formed in one wall of the casing 2 in the form of a scoop board and is designed to be let down for the removal the truck of any screenings which may fall to the bot- -'tom of the casing and which may jpe sold at the usual figure.
As shown, the fixed member 5 of the con- -veyer casing is supported by uprights 5 which project upwardly from one end. of 1 and are secured to opposite sides of the casing near its hinged end for affording a firm support for the convey er when in operation.
In the use of this improved apparatus, the
truck 1 is first moved in proximity to the binfrom which it is desired to transfer the coal to be screened and the hinged section 6 is then opened downwardly and positioned with its free end extending into the bin.
The operator then shovels coal into the hop per 7 which falls onto the conveyer 4 and is conducted upwardly and discharged onto the screen'15 of the casing 2 which isso inclined as to cause the coal to pass down-' I wardly thereover at a slow rate of speed drop 18 and 19 and the coal to pass out through I a plane whereby sufiicient to cause the dust contained therein to pass throughthe mesh of the screen and down onto'the dust guiding members the chute 16.
After the slack and dust falls onto the screening members 18 and 19 it is directed towa'rdrthe space 20 where the draft from the fan 21 strikes it and drives it across the casing 2 and out through the discharge pipe 22. This discharge pipe 22 is hingedly conwith the casing'2 and is adapted to nected be raised and lowered as required by a cable 25 and ratchet'26 which holds the cablein adjusted position after the pipe has bee disposed at the desired inclination.
. The fan 21 may be equipped with any desired number of blades and is made large enough to produce a draft suflicient only to remove the dust without blowing any of the gitudinally between the edges of these plates by the fan 21, will now sweep over the upper inner edge portions thereof, thereby blowing all of this dust out through the discharge 20,-
while the heavier particles of coal will roll downwardly 'upon the inclined plates andwill be discharged therefrom into the bottom of the casing. In so falling from these plates, the coal is again and more forcibly subjected to the will be thoroughly cleaned.- The strength to cause it to force all of the coal into the rear side of the casing away from the door 24, this being obviously an advantage.
I claim as my invention:
denly checked, thus e ectively 1arring all 'dust from this coal. The blast created loncurrent of air, whereby it of this blast of air, may be so regulated as i A coal cleaning machine comprising an upright casing, means at the top thereof for dropping coal. therein, and atransverse plate near the inner end of the casing inclining downwardly and from one side thereof,-said plate lying approximately in a horizontal to suddenly check the down- 'ward movement of coal dropped thereon,
thus jarring all dust from this coal, combined with means whereby a blast of air may be projected longitudinally of the inner edge of said plate and over the upper inner edge portion thereof. 7
In testimony whereof I have hereunto set Ly hand in presence of two subscribing witnesses. I p
