Specification of Letters Patent.
Patented Dec.31, 1912.
Application filed September 3, 1910. Serial No. 580,415.
To all whom it may concern:
Be it known that I, J OI-IN V. W. RnYNDnRs, a citizen of the United States, residing at Steelton, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in Screens; and I do hereby 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, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
My invention relates to screens, and more particularly to screens designed for handling coke, and it has for its object a simple mechanical arrangement by means of which the coke is delivered to a screen having a short travel, and is screened during the travel and dumped at the end of said travel, the screen making a little less than one revolution to effect the desired operation.
Referring to the drawings, in which like parts are similarly designatedFigure 1 is a side elevation of mechanism embodying my invention, and Fig. 2 is a section through one of the ends of the screen.
I have shown in the drawings a trestle A on which the coke quenching cars, as B, arc designed to run, said cars being brought into proper position on said trestle to discharge over a stationary inclined apron 2 which may be of screen bars or perforate plate. So much of the structure is now customarily used at coke plants, and I have adapted the mechanism embodying my invention thereto.
In the drawings I have shown an inclined track 3, which for economy in constructing it is supported partly by structural iron or other supports 4, and partly by the trestle A. It is, of course, obvious that any other suitable means may be employed for supporting the inclined track, which is preferably, but not necessarily, inclined downward from the receiving end at the trestle to the discharge end over a coke receptacle or car C. Beneath this track 3, and also extending beneath the apron, '(or screen bars) 2, is a hopper 5,'extending almost to the discharge end of the track 3. This hopper has a contracted discharge portion 6 terminating above a breeze receptacle, and preferably, as shown, terminating above an endless carrier or conveyor 7 that carries the breeze to the place where "it'. is to be dumped, or stored for further use. At one end of the track 3, or in any other suitable operative position, I place a motor, herein shown as an electric motor 8, whose rotor carries a pinion 9 that drives a gear wheel 10 on a counter-shaft 11. This counter shaft 11 is provided with a rope drum 12 around which passes an endless wire rope 13 that also passes over a guide pulley 1.4: at the discharge end of the track and one or more times around a rope wheel or drum 15 for operating a screen 16. This screen 16 is of the barrel type, with no interior partitions, and a slot or opening 17 in its periphery, preferably, but not necessarily, extending from one to the other of two imperforate or solid ends 18. On each of these solid ends is a stub shaft 19 on which is keyed a wheel 20 having flanges 21 at the rim, forming a groove. These wheels, one at each end, run on the rails 3 and the flanges 21 act as guides to prevent the wheels from slipping sidewise on the rails. On one or both of the stub shafts is the rope wheel 15 around which passes one or more times a rope 13. When the screen is longboth ends are provided with rope wheels 15, using two ropes 13, each of which passes over drums 12, both mounted on the same counter shaft 11. In other words, the structure at one end of the screen is substantially a duplicate of that at the other. A platform 22 serves to accommodate a controller 23 and the operator, who is within easy reach of the quenching car B so as to operate the discharge door thereof.
The device being in the position shown in dotted lines in Fig. 1, the operator on platform 22 discharges the quenching car over apron 2, through the slot 17 into the screen 16. The motor is then started, and the endless rope or ropes 13 cause the screen to roll on the track 3 in the direction of the arrow, until it reaches the end of the track, in which position the slot or opening 17 is in the discharging position, shown in full lines in Fig. 1. The coke falls into a freight car 0 or other receptacle, and the breeze sifted out during the travel and rotation of the screen, falls into hop er 5 and onto the endless moving carrier The operator then reverses the motor 8 and the screen is returned to its charging position. Suitable stops or buffers 24 are provided at the end of the track 3 to prevent the screen from running off the said track.
It is of course obvious that the longer the track 8, and the travel of the screen, the larIger in diameter Will be the Wheels 20.
1. The combination With a track; of 'a screen having a continuously open opening through Which the screen is charged and discharged, and means to simultaneously rot-ate the screen and cause it to travel on the track from its charging to its discharging position and vice versa.
2. The combination With 'a track; of a barrel screen having a continuously open opening in its side through Which the screen is charged and discharged, a Wheel on each end of the screen to travel on the track and driving mechanism for simultaneously rotating the screen and causing it to travel on the track.
3. The combination With a track; of a barrel screen having an opening in its side and adapted to travel on said track, a drum, means to drive it, a guide pulley near the end of the track, a Wheel on the screen, and flexible endless driving means adapted to rotate said drum less than one rotation and passing around the drum, over the guide pulley and one or more times around the Wheel, whereby said screen is simultaneously rotated and traversed.
4. The combination With a stationary inclined apron; of a track, a barrel screen having an opening in its side, adapted to travel on the track and means to simultaneously traverse and rotate the screen to bring the opening into operative position With relation to the stationary apron for charging and to move the barrel screen therefrom to discharge.
5. The combination With a track; of a screen having a continuously open opening through Which the screen is charged and discharged, Wheels on the screen adapted to travel on the track, and means to simultaneously traverse and rotate the screen.
6. The combination With a stationary inclined apron; of a track, a barrel screen having an opening in its side, Wheels secured to the screen and adapted to travel on said track, means to simultaneously traverse and rotate the screen to bring the opening into operative position With relation to the stationary apron for charging and to move the barrel screen for discharging, a hopper beneath the track and stationary apron to collect the breeze sifted. 1
7. The combination With a stationary track; of a barrel screen having imperforate or solid ends and a continuously open slot or opening extending from one to the other of said ends, a Wheel secured to each of said ends and means to traverse and simultaneously rotate the screen.
8. The combination With an inclined track; of a screen having an opening through Which it is charged and discharged, means to mount the screen to travel and rotate on the track, said screen making substantially one rotation from the upper to the loWer end of said track from charging to discharging position and vice versa.
9. The combination with an inclined track; of a screen having a charging and discharging slot open under all conditions of operation, and mechanism to rotate and traverse the screen on said track.
In testimony that I claim the foregoing as my invention, I have signed my name in presence of tWo subscribing Witnesses.
