DUMPING-OCAR.
SPECIFICATION forming part of Letters Patent No. 409,395, dated August 20, 1889.
Application filed December 17, 1888. Serial No. 293,786. (No model.) Patented in Canada January 16, 1889, No. 30,569.
To aZZ whom it may concern.-
Be it know 11 that I, JOSEPH DUFF, gentleman, of Lansing, in the county of York and Province of Ontario, Canada, have invented certain new and useful Improvements in Dumping-Cars; and I do hereby declare that the following is a full, clear, and exact description of the same.
This invention has been patented to me by Canadian Letters Patent No. 30,569, dated January 16, 1889.
This invention relates to d umping-cars such as are used in constructing and ballasting railroads, excavating and filling in, canal and dock building, for carrying ores, mining coal, and like purposes. 7
Du mping-cars constructed according to my invention are applicable for use either singly or in a train, and the main feature is the tilting of the car (thus discharging the contents) by means of a compressed-air arrangement connected with each car and with a suitable compressor located upon the engine, tender, or upon any special car or van included in the train.
A convenient arrangement of apparatus for carrying out my invention is shown in the accompanying drawings, forming part of this specification, and for full comprehension of the principles and details of construction reference must be had thereto, similar letters of reference indicating like parts.
In said drawings, Figure 1 is a plan (top) view of a dumping-car constructed according to my present invention. Fig. 2 is a plan looking at the under side of the main platform. Fig. 8 is a longitudinal section on line X X, Fig. 1. Fig. at is a transverse section on line Y Y, Fig. 1, the bucket being at rest. Fig. 5 is an end view of the car, the bucket being represented as tilt-ed or in position for discharging the load. Fig. (3 is a sectional end View showing a modification of the tilting arrangement. Fig. 7 is a detail of the air-cylinder and sliding valve.
To .void complication I have not shown the truck or wheels of the car, but simply indicate their general position by dotted lines, these being of any suitable construction and connected with the platform or car-frame in the usual or any approved manner.
A represents the main platform, bed, or frame of any suitable configuration, the apparatus which immediately accomplishes the discharge of the load being situated on the upper side of this platform, while the aircylinders, which are connected with the entire system, and their immediate adjuncts are preferably carried below the platform.
13 is the tilting-box or bucket, in this case made, preferably, in the form of a double scoop to increase its capacity, and also in order to allow the load to be discharged at either side of the track.
The apparatus illustrated in the drawings is in every case made double, (withthe exception of certain springs, which are transferable from one position to another,) this being for the purpose of allowing dumping to take place from either side of the car; but as the apparatus is fixed at starting, so that it will only work in one direction, I have simply shown the different parts in the one position, but will hereinafter explain their double or alternative operation.
The box 13 is journaled in suitable standards Z) Z), carried on the upper side of the platform, and to the projecting end of the axis of such box I mount asegmental gear C, and arrange the same to mesh into a sliding rack D, moving in proper guides a a upon the platform, and said sliding rack has two transverse slots (Z (Z, (only the former of which is now in operation for the reason above ex plained,) this slot being adapted to receive a pin 6 projecting from a sliding bar E parallel with the rack D, which travels close alongside a longitudinally slotted or grooved bar F, between which and a similar bar F, lying parallel therewith at or near the edge of the platform A, the operating-cylinder G is located. This cylinder is adapted foruse with compressed air, and has at its ends chambers g 'g, (the former of which is only now in operation,) said chambers being supplied through short branches marked g 9 respectively, which in turn communicate with a longitudinal pipe 9 from which flexible pipes g and 9 lead down to the air-cylinders underneath the platform.
G is a piston working in the cylinder G and adapted to be operated from either of the chambers g g. This piston by preference does not enter these chambers; but the piston-rod G2 passes out through the heads of both. and carries upon its ends cross-heads G G, which work in the grooved longitudinal bars F F, as shown particularly in Fig. 1.
K and L are the main air-pipes leading from the compressor (not shown) and connected between the cars of the train as usual--say in air-brakesor in any approved manner. The former pipe connects with an air-cylinder K, carried underneath the platform, having a sliding valve or piston K (shown in detail in Fig. 7,) the continuationpipe (also marked K) leading off to the next car from the port in the same manner as that described in another application for patent bearing even date herewith. The pipe g also connects with this cylinder K at a port 70, and from a port 7& connection is made by a short pipe 70 with a reservoir (or reserve cylinder) L, which in turn is supplied by the pipe L, extending through outthe train, as in my said former application, this reservoir being also in communication by a pipel with an extra cylinder M, (shown in Fig. 5 and dotted in Fig. 2,) which is for the purpose of operating the single car, the same being thrown into operation by means of a pivoted hand-lever N, in all respects similar in construction and operation to that described in my former application, and therefore needing no description here, further than to say that the pipe leads from this cylinder to the pipe g and to the chamber 9 of the operating-cylinder G.
2 2 and 3 3 are cocks in the pipe g and branches 9 respectively, the use of which will be hereinfter explained.
Then the box or bucket B is at rest in its horizontal position and the piston G is close up to the chamber 9, springs 5 5 are connected to the cross-head G and to the tops of the bars F F, and thus retain the parts in the position shown in Fig. 1@. e., just ready for this particular car to be dumped-it being understood that when the hand-lever N is thrown inward it opens the connections between the extra cylinder M and the pipe 9 as in Fig. 1, and the cooks 2 2 being opened previously air is admitted to the chamber 9 of the cylinder G, and thus forces back the piston G, the piston-rod drawing upon the sliding bar E, and causing it to travel longitudinally until the pin 6 is at the opposite end of the slot d in the sliding rack D, when by pressure against said opposite end of the slot it forces said rack along the guides or a, and by leverage between said rack and the segmental gear C causes the box B to tilt in the direction shown in Fig. 5, and thus discharge the load in that direction. hen the hand-lever N is locked in its outward position, the bucket is in its normal position and the air shut off.
P P are small rollers impinging upon the upper edge of the sliding bar E and held down upon same by being journaled in the upper ends of vertical bars P P the same passing down through apertures in the platform A and pivoted to cross-heads or cranks Q Q, which are in turn pivoted centrally to hangers Q Q depending from the lower side of the platform. To the opposite ends of said cross-heads or cranks are pivoted vertical locking-bars R R, which in turn pass up through the platform close behind the sliding rack D and segmental gear 0, which has a projection C on its side, against which the locking-bars R R will bear alternately according to the direction in which the box is to be tilted, thus holding it firmly in its normal position. Springs 4" 7" also extend from the platform into connection with the crossheads Q Q near their junction with the locking-bars, and thus give the requisite tension to the latter.
In dumping the car, as before mentioned, the movement of the sliding bar E underneath the rollers P P will serve to bring the same into the position shown in Fig. 5, when the roller P descends the incline e, (assisted by the drawing action of the spring 0",) and at the same time the roller P ascends the incline e at the opposite end of the bar E and rides upon its upper edge or into the position shown in said Fig. 5. These rollers and their connections serve to stiifen the action and support the operation of the cylinder G.
When it is desired to tilt the box 13 in the reverse direction, the springs 5 5 are released from the cross-head G and connected to the cross-head G the cocks 2 2 being closed and the extra cylinder M also shut off from. the air-pressure from the cylinder L by locking the hand-lever N in its outward position, the main air-pipe K and the cylinder K then supplying the pressure to the chamber g of the cylinder G, and thus acting upon the piston from that end. The cocks 3 3 are now open and the connection for the air made b the pipe g, the continuationpipe K leading to the next car being closed off by a proper cock if it is not desired to dump more than the one car-load at a time, or left open if the adjoining car is to be operated upon.
It is to be understood that ageneral system of cocks will be provided for the several airpipes, and the system of valves in the air-cylinders will be the same as those described in in y other application; or any other well-known or suitable arrangement may be adopted at the discretion of the builder, these being points not involving any special invention for the present case, and therefore it is not necessary that I should further illustrate or explain them.
In place of the toothed segment 0 and slid ing rack D, I may adopt a system of levers such as I have shown in the modification, Fig. 6, for tilting the box B. In this case I affix rigidly to the shaft of the box a cross head S, and to the ends thereof I pivot levers T T, which extend downward, (preferably through the platform A,) and are again pivoted to another cross-head U, which is firmly fixed upon a short shaft V, properly journaled in hangers V from the platform. To this shaft is firmly connected an upright lever XV, adapted to oscillate therewith, and in" the upper end of same I form two L-shaped grooves or slots 10 w, in either one of which the pin 6, carried by the sliding bar E,will be inserted according to the direction in which the dumping or tilting of the box 13 is to be made.
The operation of the sliding bar E, the rollers P P and their connections, and the cylinder G and its connections being precisely the same, and the segment and rack being, mechanically speaking, levers, this modification will require no further description.
I may further vary the details of construction and modify the arrangement of parts without departing from the principles of my invention.
hat I claim, and desire to secure by Letters Patent, is as follows:
1. In combination, the main frame, the bucket pivoted to tilt in either direction, a cylinder, a piston therein, pipe-connections from the ends of the cylinder to a suitable fluid-power supply, and operating-connections between the piston and the bucket, whereby it may be tilted in either direction by the piston, substantially as described.
2. In combination, the main frame, the bucket pivoted to tilt in either direction, a cylinder, a piston therein having its pistonrod extending through the cylinderhead, pipe-connections from a source of power leading to the two ends of the cylinder, a sliding bar in connection with the piston-rod, and operating-connections between said bar and the pivoted bucket, substantially as described.
3. In a dumping-car, the combination, with a main platform and a box or bucket carried thereby and capable of being tilted in either direction, a compressed-air cylinder carried by such platform and having cross-heads in connection with its piston-rod operating said sliding frame, and adapted to move the latter in either direction longitudinally, an air-cylinder having a sliding valve and supplied from an ordinary compressor and connected to both ends of said operating-cylinder, substantially as and for the purpose described.
4. In a dumping-car, the combination, with the platform and a bucket adapted to be tilted in either direction, of the segmental gear C, connected with said box or bucket, sliding rack D, having slots (Z d, sliding bar E, having pin 6 fitting into one of said slots, and compressed-air cylinder G, the piston-rod of which has cross-heads in connection with said sliding bar, substantially as and for the purpose specified.
5. In combination, the main platform, the bucket pivoted to tilt in either direction, locking-bars R R, for holding the bucket in position, a cylinder having pipe-connections from each end to a source of power, whereby the. piston therein may be moved in either direction, and operating-connections from the piston to the bucket, said connections acting upon the bars R R to withdraw one or the other to allow the bucket to turn, substantially as described.
0. The combination, with the segmental gear 0, having projection C and with the sliding bar E, of the rollers I P, vertical bars I P carrying said rollers, cross-heads or cranks Q Q, hung from the platform and connected with the lower ends of said bars, the locking-bars R R, adapted to look the segmental gear, and suitable tension-springs, all substantially as and for the purpose specified.
'7. The combination, with the sliding bar E and cylinder G, having chambers g and g, a single piston, and a piston-rod with crossheads G and G on its ends, of the air-pipe 9 connected to the chambers of said operating-cylinder and to the air-cylinders K and M, and air-pipes K and L, all arranged substantially as and for the purpose specified.
