UNLOADING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 767,548, dated August 16, 1904. Application filed January 22, 1904. Serial Nol90,l46. (No model.)
To all whom it may concern.-
Be it known that I, RALPH H. DEMPOY, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Unloading Apparatus, of which improvements the following is a specification.
The invention described herein relates to certain improvements in mechanism for handling materials, as in unloading cars, &c'. As cars are generally constructed with two hoppers or discharge-openings, it is customary to construct the receiving-hopper, which is 10- 5 cated below the level of the railway-track, of
a length somewhat greater than the distance between the discharge-openings in the car. In order that the sides of this receiving-hopper may have the necessary inclination to permit the material flowing down through the discharge-opening of the hopper to a receiver, as a transfer-belt or conveyer, &c., which is arranged below the hopper, the pit or excavation below the track must be quite deep. 5 The present invention has for its object such a construction and combination of hopper, discharge and receiving mechanism as will avoid the deep pits now necessary and will consequently avoid the loss due to the extra vertical lift incident to the deep pits.
The invention is hereinafter more fully described and claimed.
In the accompanying drawings, forming a part of this specification, Figure 1 is a top plan view of my improved car discharging or unloading plant. Fig. 2 is a sectional elevation on a plane indicated by the line II II,
Fig. 1. Figs. 3 and 4 are transverse sections on planes indicated, respectively, by lines III 4 III and IV IV, Fig. 2.
In the practice of my invention I provide one, two, or more hoppers 1, which are arranged in a pit or excavation below a line of track 2 or adjacent to a line of track, as 3. In
the former case the material would drop directly into the hopper or hoppers, while in the latter case a chute 4 is provided for conducting the material from the car to the hopper. The sides of the hopper or hoppers are given an inclination somewhat greater than 5 the angle of rest of the material tobe unloaded, so that such material will flow down onto a discharge-platform 5. This platform extends beyond the discharge-opening 6 of the hopper, said opening being made in one of the sides of the hopper such a distance that the material flowing through such opening will be stopped by and rest upon the platform. In other words, a line, as as, drawn from the upper edge of the opening 6 and having an inclination corresponding to the angle of rest of the material will not pass beyond the end of the platform. By this construc tion any material flowing from the hopper onto the discharge-platform will be retained 5 thereon, requiring the use of a pusher to dislodge it. This dischargeplatform is provided with side or retaining plates 7 to prevent the material from dropping over the edges of the plate or platform 5. 7
The material is forced from the platform 5 by a pusher 8, which is reciprocatecl in any suitable manner, as by a crank-pin 9 on the power-driven shaft 10 and connected by the pitman 11 to the pusher. The means employed for discharging the material from the hopper is substantially similar to that described and claimed in application, Serial No. 131,925, filed by me November 19, 1902.
The discharge end of the platform 5 extends over a suitable receiver, which may be of any desired form or construction. In the construction shown, where the material is to be transferred directly, 'I employ a belt 12, passing around pulleys 13 and 14, one of which 5 is driven and supported intermediate of the pulleys by two series of rollers 15 and 16. As
.shown in Fig. 4, the rollers 16 are so arranged as to turn up the edges of the belt so as to form a continuous pocket for the reception of 9 the material. The inclination and length of this conveyer will be dependent upon the distance and elevation of the point to which the material is to be conveyed.
It will be understood by those skilled in the art that the discharge-platform 5 may extend horizontally from the lower end of the hopper or at an upward or downward inclination therefrom, provided the angle of upward inclination does not exceed the angle of rest of the material. When two hoppers are employed, the receiver, as the conveyer-belt, is arranged between them and the dischargeplatforms extend in opposite directions over the conveyer. As stated in the application referred to, the rate of discharge of the material is controlled by the reciprocating pusher and can therefore be adjusted in accordance with the rate of travel of the conveyer.
It is characteristic of my improvement that the position of the receiver is not dependent upon the position of the hopper, as the discharge-platform can be extended to any desired distance and in any desired direction from the hopper and within certain limits at any desired angle from the lower end of the hopper. The receiver is so arranged that the part or point at which material is deposited thereonto may be above the plane of a side, as a, of the hopper.
I claim herein as my invention v 1. In an apparatus for handlingmaterial the combination of a receiving-hopper discharging horizontally and having a stationary point of delivery, a conveyer moving in or approximately in a horizontal plane at an angle to the direction of discharge of material from the hopper and so arranged at one side of the discharge-opening of the hopper that the point at which the material is received by the conveyer is above the plane of the side of the ho pper, substantially as set forth.
2. In an apparatus for handling material the combination of a conveyer and two or more hoppers so arranged with reference to the conveyer that the point at which the material is received by the conveyer is above the plane of the sides of the hoppers, substantially as set forth.
3. In an apparatus for handling material the combination of a hopper discharging horizontally and having a stationary point of delivery, a conveyer moving in or approximately in a horizontal plane at an angle to the direction of discharge of material from the hopper and so arranged that the point at which the material is deposited on the conveyer is above the plane of the side of the hopper, and means for causing the movement of the material from the hopper onto the conveyer, substantially as set forth.
4:. In an apparatus for handling material the combination of two or more hoppers, a conveyer having the point at which the material is deposited thereon above the point of intersection of planes coinciding with the sides of the hoppers, and means for causing the movement of the material from the hoppers onto the conveyer, substantially as set forth.
5. In an apparatus for handling material the combination of two or more hoppers, means for causing a regulated discharge of material from said hoppers, and a receiver arranged above the intersection of planes coinciding with the sides of the hoppers, substantially as set forth.
In testimony whereof I have hereunto set my hand.
