CAR HANDLING AND DUMPING DEVICE.

SPECIFICATION forming part of Letters Patent N0. 721,089, dated February 17, 1903.

Application filed December 16, 1902. Serial No- 135,427. (No model.)

To all whom it may concern: 7

Be it known thatI, ERSKINE RAMSAY, a citizen of the United States, andaresident of Birmingham, Jefierson county, State of Alabama, have invented certain new and useful Improvements in Car Handling and D u mping Devices, of which the following is a specification.

My invention relates to devices for handling cars containing coal and other minerals, &c., and dumping the same; and my objects are to provide a device of this character which will receive a loaded car or cars of coal, ore, and other substance from the point of supply, such as a mine-shaft or slope-mine, and transfer the same to a tippling or dumping structure and thence dump the said cars into a hopper or other receptacle for distribution to shaking screens, cars, or bins, and to so construct such a device that the operations may be automatic and under the control of a single operator from the time the loaded car is received from the mine, as from a cage in a shaft or aslope, the empty cars being automatically returned and transferred to said cage or slope for transportation to the mines for reloading; and my further object is to provide such a handling and dumping structure as will permit the performance of the operations designated in practically a continuous manner and will likewise admit of the switching of the empty cars or loaded cars either through or from the rotary tipple structure for transfer to the repair-shops or boilers of the plant; and my object is, finally, to construct a car handling and dumping structure of the character indicated which will insure the transportation of the loaded car or cars from the mines in the most expeditious and safe manner and will embody the simplest and most durable construction of parts for efiecting the purpose desired, and which, moreover, will be susceptible of application either to the slope -mine or to a shaft-mine or to any suitable source of supply from which the material is to be transported in cars, then dumped and returned for reloading.

In the drawings I have shown my car handling and dumping device in connection with a well-known type of transfer and discharge apparatus-such, for example, as the Robert Ramsay transfer-rams disclosed in Patent No. 404,656, granted to Robert Ramsay June 4, 1880; but it is to be understood that my invention is applicable to mines or other source of supply where such transfer apparatus is not employed or needed, as well as in connection with other transfer apparatus.

With these objects in view my invention consists in the combination of means for transporting a loaded carfrom the mines or other source of supply, means for transferring said car to a rotary or dumping tipple, means for causing the latter to invert the car and to discharge its contents into a suitable place, and means for returning the empty car so discharged to the point of supply; and it further consists in the combination, with such means, of mechanism for efiecting the automatic operation of the several functions specified; and it further consists in the novel construction of car handling and (lumping apparatus as hereinafter described with reference to the accompanying drawings and in the details thereof, as more particularly pointed out in the claims.

In the drawings, Figure 1 is a plan view of a structure embodying my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a transverse vertical section on the line 3 3, Fig. 1, looking in the direction of the arrow a. Fig. 4 is a similar view on the line 4 4, Fig. 1, looking in the direction of the arrow b. Fig. 5 is a sectional detail hereinafter referred to. Fig; 6 is a top plan View of a modification of the structure shown in Figs. 1 to 4. Fig. 7 is a top plan view of a further modification. Figs. 8 and 9 are transverse vertical sections thereof on the lines 8 8, Fig. 7, showing the rotary tipple in difierent positions; and Fig. 10 is a longitudinal section on the line 10 10, Fig. 9.

Referring to thedrawings, in which the same reference characters relate to the same or corresponding parts in all the, views, the letter X indicates throughout the structure a suitable supporting-framework consisting of beams, girders, &c.,' properly arranged for supporting the various tracks for the cars in running from the cage of the mine or other place to the tipple and for the transfer of the tipple from a transporting-track to a returntrack in dumping and for the transfer of loaded or empty cars to the repair-shops, boilers of the plant, &c.

Referring particularly to Figs. 1 to 5,which show the invention in connection with a shaftmine, N indicates an ordinary mine-shaft, in which a cage N is hoisted in position by the usual hoisting means for elevating a loaded car Y to the level of the transporting-tracks P P, the latter being in juxtaposition, and such cage in Fig. 2 being in position to bring the tracks thereon in alinement with the transporting-tracks P, over which the car passes toward the rotary tipple A. Located on opposite sides of the shaft or point of supply, in the present instance the shaft of a mine having the vertically-moving cages N are the transfer structure and the rotary-tipple dumping structure, the latter preferably consisting of rotary tipples similarly constructed to the rotary car-dumping structure, such as that disclosed and claimed in my patent dated June 3, 1902, No. 701,764; but any suitable rotary tipple may be used where the conditions warrant or require with means for moving it along a track or way as it rotates, as hereinafter described.

In order to expedite the handling of the material, I have preferably used two sets of transfer-trucks K and K in connection with two rotary tipples A and A, the latter being mounted on a way transversely intersecting the tracks. These transfer-trucks are mounted upon tracks 70, extending transversely with respect to the tracks 0, P, P, and-O, and inclined downwardly from the central axis of the structure, as shown in Fig. 3, so that the depressed ends of said track or way may aline with-the downgrade return-tracks O and 0. These transfer-trucks bear suitable rails for holding the cars and are fixed at such distance apart that when the truck K alines with the track 0 the truck K is in alinement with the track P and when moved from'the position shown to the extreme position in the other direction the truck K will aline with the track P and the truck K with the track 0. The truck K is designed to receive the empty car from the track 0 and transport it to a point opposite the track P, in which position it is utilized to push the loaded car Y from the cage onto the track P, leading to the rotary tipple A, down which track P, on account of the sloping grade toward the tipple, said car will run by gravity into the tipple, while the empty car, under the action of the ram L, pushes the loaded car, as stated, and takes its place on the cage ready for lowering or for return to the mines or other place, and, similarly, the transfer-truck K receives the empty car from the track 0 and transfers it to a point opposite the cage whose tracks aline with the track P, and is similarly used in connection with the ram L to push the loaded car onto the track P, down which the car travels by gravity into the rotary tipple A when the latter has been transferred to that point.

In order to effect the transfer of the trucks K and K from one set of tracks to the other for the purpose [above indicated, a motivepower cylinder J, fixedly mounted on the sup'-.

porting structure below the transfer-trucks, is provided with a piston-rod j, extending through opposite ends thereof, and to the ends of which are attached ropes 1 and 3. These ropes pass around the sheaves I,mounted at the outer edge of the supporting structure upon suitable fixed bearings, and are attached to the trucks K and K, (see Fig. 3,) so that a stroke of the piston-rod causes the trucks to move to the other set of tracks. On the ends of the piston-rodj are mounted suitable pulleys H. The rope 1 is also fastened to the end of the piston-rod j, from which it passes around the fixed pulley G, then around the pulley H, back around the pulley G, then to the opposite side of the structure around the deflecting-pulley F, and thence to the pulleys G and B and around and secured to the rotary tipple A, the rope 3 being similarly rove with respect to the tipple A, see Figs. 1 and 3. The movement of the piston-rod in one direction will cause the transfer-trucks to traverse its tracks from one point of the set of transportingtracks to the returntracks. At the same time that this movement occurs the rotary tipples A and A are caused to move in the opposite direction thereto, and in so moving they make one complete revolution in order to first reverse the car for discharge of its contents and then right the empty car into position for delivery from said tipple, and as a convenient and preferable mode of accomplishing this result and in arranging the same so as to occur not only simultaneously with, but in opposite direction to, the movement of the transfertrucks I wind the rope 1, after passing from the guide-pulley F, around the fixed pulley O, secured to the fixed structure near the rotary tipple, thence around the guide-pulley B, and thence around the grooved rings A on the rotary tipple A from one side of the structure, the other rope 3 leading around the grooved rings A on the ti pple A from the other side of the structure, by which means it will be observed that, assuming the tipples to be capable'of movement across the structure as they are rotated, movement of the piston-rod of the motor power device J in one direction will cause the transfer-trucksKand K to move in the opposite direction thereto and through the medium of rope-gearing 1 and various guide-pulleys to impart a motion of translation to the rotary tipples in the opposite direction. In order to provide for this translation of the rotary tipples and at the same time to preserve a fixed distance between the same equal to the distance between the centers of the tracks 0 and P and between the ICO centers of the tracks 0 and P, I mount the passing through the tipple.

teeth E and supporting-rings A on the tipple have corresponding holes A thus constituting a rack and pinion, the teeth meshing with the holes A on the said rings as the tipples are revolved. As a further means of causing the tipples to rotate a nd preserve their fixed distance apart I wind a rope 2 around a grooved ring A of the tipples, so that when either the rope 1 or the rope3 pulls the tipple said rope 2 will cause the tipple to rotate with the one in-advance.

It will be observed that with the piston in the cylinder J as shown and the ropes 1' and 3 rove in the manner described and shown the movement of the rotary tipples will be twice the length of a piston-stroke, and as they move this distance one pays off as the other winds up the rope with reference to a fixed point an amount equal to twice the distance of travel of the said tipples. Hence the tracks P and P must be laterally disposed at a distance twice the length of the piston-stroke, and it is absolutely necessary that the tracks and tipples upon which the cars are supported shall aline with the loading and discharging or return tracks when the tipples are transferred from one to the other, which result is insured by the rack-and-pinion engagement between the rotary tipple and its transferringtrack. In order to prevent the loaded car from passing through or partly through the tipple as it travels by gravity into the same over the tracks P and P, I provide automatically-actuated bumpers D and D on opposite sides of the tipples, such bumpers being normally in the position shown, so as to engage a fixed part of the car-as, for example, by means of a suitable spring 01, as shown in Fig. 2so that as the car travels down the track it will depress the bumper D, and the latter immediately after the car enters the tipple will automatically resume its position and prevent backward movement of the car, while the bumper D, oppositely disposed to the bumpers D, will prevent the car from When it is desired to permit the car to pass through the tipple, either loaded or empty, to the repairshops or boilers, such transportation will be efiected by means of the depressing-lever D which is arranged to depress the bumpers D in order to permit the car to travel over the same, the tracks 0 O and P and P being continued and provided with suitable switches shown in the proper direction for switching at the point desired. A similar arrangement for preventing the movementof the empty car beyond the transfer-truck is utilized on opposite sides of said truck, as shown in Fig. l, where similar reference characters relate to similar automatically operating bumpers above described. The bumpers-D, however, are preferably not provided on the tracks 0 and O, as it is desirable that the empty car shall pass out of the tipple immediately after the latter reaches the tracks 0 or O, and to prevent the empty car from passing beyond the track opposite the transfer-truck unless and until the said truck is in alinement with said tracks to receive the car automaticallyoperating dogs W are located in advance of the bumpers, and the said dogs W are carried by crank-arms w on a shaft wiwhich'is normally held in such position by the weight of the dogs as to throw the dogs across the track in line with the car,(see Fig. 3,) and thus stop the same as it descends the tracks toward the transfertruck, such tracks being on a slight downward grade in order to allow the car to run by gravity from the tipple toward the said trucks; .but when the transfer-trucks are brought into proper position a fixed part on the truck engages an arm w of the crankshaft, elevates the same, and swings the dogs away from the track out of possible engagement with the traveling car.

Between the two tracks P and P a suitable hopper Q is located, into which the rotary tipples are discharged as they traverse back and forth across the tracks, such hopper be ing shown as adapted to discharge into a screening device, that shown, for example, being adapted for screening coal, and assuming coal the material being handled such coal will be discharged intd the upper screen R, which separates the lump from the nut and slack, the former passing into the conveyer V, whereby it is carried to cars or to bins or other places, while the latter mixture falls through the meshes of the screen R onto the screen S, which separates the nut from the slack, the latter falling into the chute T, after which it is directed into cars on tracks beneath the same or to other points, the former passing down the chute over the end of the screen S onto a conveyer U and discharged likewise into cars or other places.

In order to provide for the tilting or inclination of the tipples A and A to correspond with the grade of the tracks with which they are in alinement for receiving loaded cars and discharging empty cars, the rail E is depressed from the center of the track P and across the track 0 and from the center of the track P to and across the track 0, thereby causing the tipples to incline toward the transfer structure, as shown in Fig. 2.

From the foregoing description the mode of operation'will be clearly understood, and, briefly stated, it will be noted that when the tipples are in the position shown in Fig. 1 an empty car is on the transfer-truck K and is pushed therefrom by the ram L, thereby moving the loaded car Y from the cage onto the track P into the tipple A, the empty car taking the place of said loaded car on the cage. The operator, who may be stationed between tracks P and P and between the cages and the transfer-trucks, now moves a lever connected to the stem g of the valve (1 of the cylinder J, Fig. 3, admitting motive fluid thereto and causing the piston to travel in the opposite direction to that shown, which pulls the rope 3,'thereby transmitting motion to the tipple A, causing the same to move to the opposite side of the structure and in its motion to revolve on the tracks E and E, discharging the contents of the car into the hopper Qas it passes over the same, the rope 1 being paid out to the same extent as the rope 3 is pulled in by the traveling pistonrod. At the same time the transfer-trucks K and K are moved in the opposite direction, so as to bring the truck K opposite the track P and the truck K opposite the track 0, and the empty tipple A is now brought into position opposite the track I, and as the tipple A moves from the center of track P to the center of the track 0 the depression causes the forward end to tilt in the direction shown in Fig. 2, thereby automatically starting the car from the tipple onto the track 0, down which it runs toward the transfer-truck, and at the same time the ram L may be operated to push the empty car from the truck K onto the cage, which has now arrived in position through the shaft N, thus forcing the loaded car thereon to the track P and into the tipple A, and movement in the opposite direction will effect the same sequence of operations.

To prevent the tipple from moving too far in either direction, the tracks E and E are preferably curved at the end to form bumpers e, as shown in Fig. 44-, and the cars while in the rotary tipple/s are preferably maintained in fixed relation thereto by means of brackets a, such as that disclosed and claimed in my prior patent, already referred to.

In the foregoing construction the parts are designed with reference to the use of one or more, preferably two, rotary tipples; but in some cases it may be desirable to employ one, in whichevent a suitable arrangement of switches for switching cars from one track to the other, such as that shown in Fig. 6, may be employed, wherein it will be noted that the tracks 0' and P and O and P, respectively, are connected by switches 0 and 0 and a single rotary tipple A is used instead of two, the ropes l and 3 passing around the grooves A and fastened to the ring A of the tipple A, and leading to the fixed guide-pulleys B, C, F, and G to the pulleys H on the piston-rod j, and then fastened to a fixed position, as shown. In this arrangement the travel of the rope would be two times the stroke of the piston, while the travel of the tipple would be the same as that of the piston. Such an arrangement may, in some cases, be preferable, as it is possible to dispense with the use of one of the tipples as well as the connecting-rope usually employed'between the two tipples. The operation of this structure is otherwise the same as that hereinbefore described, and the parts indicated are of the same form and construction and mode of operation, the same letters indicating such parts.

In some cases it maybe advisable to modify the construction for special adaptation to 721',ose

other mines, in which cases the particular form of tipple shown in connection with the previously described construction is not needed, and consequently the tracks leading to the rotary-tipple structure are modified, as shown in Figs. 7 to 10, by reference to which it will be seen that the tracks P and O are so located as to return the empty car at opposite ends of the extreme limit of movement of the rotary-tipple structure A. These tracks are provided with switches o and 19 leading to the transfer-truck, if the latter is used, or the slope, if not used. The movement of the tipple structure from one side to the other of this track in order to effect the discharge of the loaded car is accomplished in a similar manner by means of the cylinder J, from the piston-rod of which extends a rope attached to the tipple A, the latter of which is mounted upon a truck A, which travels upon tracks E and E, as before, a shield A extending from both ends of the truck to deflect the contents of the car as it is dumped into the hopper Q. In this construction it will be noticed that the transfer trucks K and K and the cages N N are located the same asin Fig. 1, theloaded tracks leading from the cages to thetipple and the empty tracks leading from the tipple to the transfertrucks. A loaded car is received from the cage over the track 0 and dumped in going to the track P where the empty car passes out of the dump to the transfer-truck. The same, but opposite, movementtakes place when the loaded car is received from the cage over the track P Where this form of dump or, indeed, the other is used at a slope-mine, the transfer-trucks are dispensed with, the loads being received from the loaded track, here shown as the cage-track, and returned on the empty track, here shown as the transfer-track. In this form the rotary tipple A is mounted on spur gear-wheels F, carried on a common axle with smaller gears F, the latter meshing with the tracks E while the former mesh with the ring G on the tipple. A complete revolution of the ti pple can therefore be effected in any desired travel of the tipple by properly proportioning the diameters of the spur-wheels F and F. The dump should have its track on which the mine-car runs on an upgrade, as shown in Fig. 10, and one of the tracks E should be depressed, as shown in said figure, so that the loaded car, having sufiicient momentum, will run into the tipple, and when the contents are discharged by the rotary movement of the tipple the said car, now empty, will automatically run out of the dump and down the grade to the transfer-truck or other place. With this construction it is obvious that if the travel of the tipple is the same as that of the transfer-trucks when such are used a. single direct connection from the piston-rod of the cylinder J is sufficient, thereby dispensing with the sheaves or pulleys G and H.
