To aZZ whom, it may concern:
Be it known that 1, JOHN MOMYLER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Aprons for Car-Dumping Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.
This invention is for use in connection with machines which lift a loaded car and turn it over, thereby dumping its contents onto an inclined chute or apron. Such machines are commonly used for dumping cars loaded with coal, and one function of the apron is to convey the coal dumped onto it to a dischargespout, through which said coal is carried into the holds of vessels.
The coal is liable to be broken during transit or while being dumped, and it is the object of this invention to screen out the slack and small pieces while the coal is sliding down the apron.
The invention may be summarized as the combination, with the inclined apron, of a cardumping machine, or substantially such an adjustable screen as is shown in the drawings, and hereinafter described and claimed.
In the drawings, Figure 1 is a plan view of an apron to which my invention is applied. The drawings, however, show the screens applied only to the three left-hand sections of said apron. Fig. 2 is a side elevation, the upper part of the apron being shown in section. Fig. 3 is a plan view of a portion of the apron, showing the right-hand screen-section. Fig. 4 is a plan view of one of the adjustable sections, and Fig. 5 is a sectional view taken in the plane of the line 5 5 of Fig. 3.
Referring to the parts by letters, A represents an inclined apron, which is generally of the form' commonly employed with car- At its wide upper end it is pivoted ona horizontal pivot bto a girder B in the usual way. The floor of this apron below the screens is indicated by a in Fig. 2, and this floor rests upon a plurality of longitudinal beams a, which, together with suitable transverse beams, constitute what may be called the frame of the apron. This floor, however, is absent from the upper part of the apron, and its place is supplied by the screening device. T his device includes a plurality of cylindrical bars C, which may be hollow. The u per ends of these bars are passed through iioles in an upwardly-extendlinks F, with the upper transverse beams a I of the apron and are thereby prevented from moving toward the lower front end of the apron and also from moving transversely. There are as many of these frames and their.
bars E as there are sections between longitudinal beams a.
Two shafts G extend transversely of the apron and beneath all of these frames and are mounted in suitable bearings. To these bars numerous cams g g are secured, and these cams engage with the bars H, which are secured to the frames D, but are adjustable thereon, said bars, however, being rigid parts of said frame when the described mechanism is ready for use. Referring specifically to the manner of connecting these bars" with said frames, it will appear from the drawings that each bar is pivoted to the frameand that its free end engages with a bolt h, which passes through it and a part of the frame and 'has an adjustable nut it just above and in contact with the bar H. On the right-hand end of each of the shafts g g are bevel-gears g 9 respectively, which engage with bevelgears j, secured to a shaft J, and this shaft is provided with a hand-wheel or some other convenient means for turning it. It is obvious that by turning this shaft J both of the shafts G will be turned, whereby their cams will raise the frames B more or less or permit them to drop more or less, and thereby vary the width of the spaces between the bars C and E, through which the screened material must pass. The barsHare made adjustable, because there will be many of the frames D, and it will require exceedingly nice Work to construct them in the shop so that when put onto the machine the bars E, which they carry, will all be precisely at the same distance from the bars G. Since the bars H are adjustable, however, this furnishes means ior adjusting the frames and their bars E after.
said frames are put into the machine, so that the distance between the bars C and E is uniform throughout the entire width of the IIC apron. A bridge-plate K is pivoted to the girder B and it extends over and rests upon the flange a and thus it prevents coal dumped from the car from falling down between the apron and the girder and compels all of said coal to flow on to the screen, which has been described. Below these screens is the floor A, onto which the material which passes the screen-bars will fall, and this screened material sliding down said floor will flow into the tube M of the screen conveyer, which is constructed substantially as shown in my prior application, and it is associated with cooperating parts, as shown in said application.
Having described my invention, I claim 1. In a car-dumping machine, the combination of an inclined apron which includes in its construction a plurality of parallel longitudinalbeams, floor-plates securedupon the lower-parts of said beams, and a plurality of parallel longitudinal bars secured between the upper parts 01 said longitudinal beams at substantially the level of said floor-plates, with a plurality of frames located severally between said longitudinal beams and below said. bars, a plurality of longitudinalbars secured to each of said frames, and means for supporting said frames and adjusting them toward and'from said upper bars.
2. In a car-dumping machine, the combi nation of an inclined apron which includes in it'sconstruction a plurality of parallel longitudinallbeams, floor-plates secured upon the lower-parts of said beams, and a plurality of parallel longitudinal bars secured between therupper parts of said longitudinal beams at substantially the level of said floor-plates, with a plurality of frames located severally between said longitudinal beams and below said-bars, a plurality of longitudinal bars secured to each of said frames, shafts extending transversely of the apron and mounted in bearings supported by said longitudinal beams, and means carried by said shafts for adjustably supporting said frames.
3. The combination with the verticallymovable apron-supporting girder of a cardumping machine, an apron hinged thereto and capable of being held at various inclinations, which apron has a floor over its lower part, and an upwardly-extended transverse flange near its upper end, a plurality of longitudinal bars whose rear upper ends pass through holes in said flange and Whose front lower ends are fixed upon the floor of the apron, a bridge-plate pivoted at its upper end to said girder and having its lower end supported on the apron and extended over the upper ends of said bars, and a plurality of longitudinal bars located below the spaces between the bars first named.
4. In a car-dumping machine, the combi nation of an inclined apron, whose floor at the upper part of said apron is composed of a plurality of parallel longitudinal bars, a plurality of frames located beneath said bars, and having each a plurality o1 longitudinal bars secured to it, shafts extending transversely of the apron, and a plurality of cams secured thereto engaging said frames, and links connecting the upper end of said frame with the apron.
5. In a car-dumping machine, the combination of an inclined apron, whose floor at the upper part of said apron is composed of a plurality of parallel longitudinal bars, a plurality of frames located beneath said bars, and having each a plurality of longitudinal bars secured to it, bars adjustably secured to said frames, shafts extending transversely of the apron, and cams secured to said shafts engaging with said adjustable bars, and means for simultaneously rotating the shafts' In testimony whereof I hereunto affix my signature in the presence of two witnesses.
JOHN MOMYLER.
