DUST-DISTRIBUTING CAR.

Application led'December 29, 1924. Serial No. 758,750. .i

To all whom t www concern.:

Be it known that I, ROBERT. D. BEA'rrY, a citizen of the United States, residing at Birmingham, in the county o-f Jederson and State of Alabama, have invented a new and useful Dust-Distributing Car, of which the folllowing is a specification.

This invention aims to\ provide a novel /form of distributing car which may be used for rock dusting coal mines, the invention comprising novel means for feeding the dust from the car, and for distributing the dust in the mine. I

It is ywithin the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

`With the above and other objects in View which will appear as the description proceeds', the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings Figure4 1 shows in top plan, a device constructed in accordance with the invention; Figure 2 is a side elevation ;l Figure 3 is a longitudinal section on the line 3--3 of Figure l; Figure 4 is an end elevation; Figure 5l is a transverse section; Figure 6 is a section ltaken on the line 6-6 of Figure 1; Figure 7 is a section taken on the line 7-7 of Figure 1.

The car comprises a body 1 which may be made in variousways, without jeopardizing the utility of the invention. As shown, but not of necessity, the body comprises ends 2 and 3, sides 4 and downwardly and inwardly slanting vbottom members 5. End cross pieces 6 and intermediate cross pieces 7 are connected to the bottom members 5.

The frame 8 lof the car, like the body 1, maybe made in many wayswithin the scope of the invention. In order to present a concrete embodiment, the frame 8 is delineated as including side bars 9 and end ing similarly connected to the intermediate cross pieces 7 of the body 1. Axles 15` are supported ai; 16 onthe side bars 9 of the frame 8, and carry wheels 17 adapted to move along a track 18. v

At the longitudinal center of the body 1 and at the lowermost portion of the body is located a trough-like member 19 which extends longitudinally of the car, the member 19 having lateral flanges 2O which are connected to the body forming members 5. At one end, the trough-shaped member 19 is closed, as shown at 21, in Figure 3 by a portion ofthe lend 3 of the body 1, the opposite end of the member 19 communicating with a vertical, chute 22, as shown at 23, the chute being mounted on the end 2 of the body 1. As shown `at 63, the chute'22 communicates with a conduit 24 which extends through the lower portion of thechute, the conduit being disposed longitudinally vof the car. Above the conduit 24, the chute 22 carries a removable screen 25.

i The conduit 24 has an upwardly extended end 26' communicating with a suction and blower mechanism'27 mounted on a platform 28 carried by the side bars 9 of the car frame 8.- YThe shaft `29 of the suction and blower mechanism 27 is coupled, as shown at 30, to the shaft 431 of a motor 32 mounted on the platform 28. The motor 32 may be of any desired sort, but it is suggested that an electrical motor be used if considered desirable. The shaft 29 of the suction and `blower mechanism 27 carries a beveled pinion 33 meshing with a beveled gear 34 on av shaft 35 extended longitudinally of the car,

the shaft being j'ournaled in a bearing 36 on the platform 28. At its inner end, the shaft 35 is supplied with a beveled pinion 37 mesh# ingwith a beveled pinion 38 on a shaft 39 disposed transversely of the. car, the shaft 39 being journaled in a casing 40 supported by a hanger 41 on the end 3 of the car body 1.

Within the i casing 40, the shaft 39v is equipped with a worm 42, meshing wi a worm wheel 43 on'a shaft 44 extended longitudinally of the member 19 and journaled in the casing 40, in the part-21 of the end wall 3 of the car body, and inl the chute 105 angle member, extended between the ends' 2and 3 andsupported upon and connected an inverted angle member, is mountedy for" reciprocation onthe grate 46, ythe slide 47 .and the grate 46 bein equipped with openinv` s 48 which are a apted, to be` brought in o registration when the slide is' moved .endwise'u The slide 47 carries laterally extended rakes 49, which move in close prox.

imity to the bottom members 5. At one end, the slide 47 has an arm 50, mounted toreciprocate in the .end 2 of the car body 1, the arm 50 being connected-in any suitable way, as shown-at 51, to the lower end of an operating member 52, preferably a lever,

the lever being fulcrumed intermediate its ends, as shown at 53, on the end 2 of the 'car body 1. c

In practical operation, the finely divided material with which the mine is to be dusted, is placed in the car body,v 1. Through 'the medium of the lever 52, the slide 47 may be moved endwise, so as to bring the openings 48 to the slide and of the grate 46 more or less into registration, thereby to regulate the amuont of material which passes downwardly into the trough-shaped member 19, and to cut off the supply of material to the trough-like member 19, upon occasion. The material, passing through the openings 48 of the slide 47 and the grate 46, is engaged bythe screw converyor and is advanced to the right in Figure 3, the material passing into thevertieal .chute 22, the screen 25 exercising its obvious oiiice. From the chute 22, the material passes through the o enin 63 into the conduit 24,

-and when ab ast o air passes through the conduit, the-dust or material is driven out 1nto the mine and distributed through a suitable nozzle (not shown).

The blast of air throughthe conduit 24 is createfd, of course, by the suction and blower mechanism 27, the shaft 29 of the suction and blower mechanism being driven -rom the shaft 3l of the meter 32. The

driving train for the shaft 44 which carries the conveyor 45 includes the beveled pinion 33,' the beveled pinion 34, the shaft 35, the beveled ygear 37, the beveled. gear 38, the shaft 39, the worm 42, .and the Worm wheel 43. Y

Having thus described the invention,

what is claimed is ,1. In a device of the Rclass described, a

lwheel-mounted frame, a body carried by the frame,a blast conduit supported by the frame, means for producing ablast in the conduit, a conveyor in the body and discharging into the conduit, means for operating the` conveyor, and mechanism for regulating .the flow of material from the body to the conveyor, said mechanism being movably under the control of an operator and practically equal in length to the conveyor thereby to securean even supply of material to the conveyor, a perforated slide mounted to reciprocate on the grating and governing the low of material from-the body to the conveyor thereby to avoid a clogging of the conveyor, a longitudinal blast conduit into which the trough-shaped member discharges at one end, meansfor supplying a blast to the conduit, means under the control of an operator for moving theI slide, and means for operating the conveyor.

In testimony that I claim the foregoing as my own, ture.

ROBERT AD. BEATTY.
