- the car truck T is mounted on wheels W and carries a central longitudinal bar L, to which at H is hinged the car body B having fixed ends E and movable sides S.
- the construction may follow that disclosed in my prior patent, or that of ordinary coal or ore cars commonly employed and which dump to either side, and the details, proportions, and materials of parts are not essential to the present invention.
- C are illustrated catches carried by the body B, and one of them engages one of the keepers K carried on the truck as set forth in my prior patent.
- each side board is rigidly mounted at the outer end of a sector-shaped casting constructed as best seen in Fig. 6, and as the means for connecting the side boards S thereto are unimportant, I designate them broadly herein by the numeral 1.
- Such fastening device 1 is carried by an upright plate 2 which is cast over the outer edge of an are 3, and in a brace between the plate and are is disposed a pin or stud l to which one of the chains 5 may be hooked if desired.
- the are is supported by two arms 6 and 7 which converge toward and merge into a hub having an eye 8 disposed at the center of said arc, and this eye is pivotally mounted on a bolt 10 which is fixed through the car end Ea bushing 9 being by preference interposed between the bolt and the inner wall of the eye 8.
- the angle of the plate 2 (and therefore of the side board S) to the upper end of the are 3, and its disposition with reference to the pivot bolt 10 is such that as the side board starts upward from the posi ion shown in Figs. 1 and 3 it moves slightly away from the beveled end e of the end board E, and finally reaches the position shown at the right of Fig. 2.
- a bolt 11 having at its inner end an eye 12, its body along its outer side being provided with a stop 13 and the eye with another stop 141, the outer side of said body having a longitudinal rib 15, its outer end having a lug 16 with a downwardly facing shoulder 17, and the outer extremity of said body forming the tip 19 of the bolt, said tip being adapted to travel in a groove 20 in the radial inner face of the are 3 of the casting shown in Fig. 6.

- the shaft has flattened sides 56 engaged by a spring 57 to hold it yieldingly in various positions.
- Sheet 3 of the drawings also shows how the coiled expansive spring 44 located within the pocket 43 may be replaced by a coiled expansive spring 64: surrounding the main bolt 10 under its head 10 and located within a pocket 63 formed in the outer face of the cam; and if this construction be adopted it is clear that before the lever 40 can be thrown it will have to be bodily drawn outward on the main bolt so that its groove 47 will disengage the rib 15, whereas with the construction shown in Figs. 7 and 8 the lever 40 need be sprung outward at its handle end only and for a distance sufficient to disengage said groove from the rib. As above suggested, this detail also is unimportant, and either described form or any equivalent form may be employed.
- a locking bolt 11 having a shoulder 17 adapted to engage a shoulder 3 in the runway or groove 20 when said bolt is pro jected, such engagement preventing the elevation of this side of the car body B; therefore the car cannot be dumped to the opposite side, although it is yet possible to dump it on this side.

DUMPING-CAR.
Specification of Letters Patent.
Patented May 5, 1914:.
Application filed April 3, 1913. Serial No. 758,628.
To all whom it may concern:
Be it known that I, JOHN KARHU, a citizen of the United States, residing at Calumet, in the county of Houghton and State of Michigan, have invented certain new and useful Improvements in Dumping-Cars; and I do 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.
This invention relates to railway rolling stock, and more especially to laterally tilting dumping cars and the object of the same is to effect certain improvements over my former Patent Number 1,046,602, dated December 10, 1912.
WVith this object in view the invention consists in certain details more fully described hereinafter and brought out in the claims, and the same are illustrated in the accompanying drawings wherein- Figures 1 and 2 are .end elevations of a car embodying my improvements, the former showing the body as upright and the latter view showing it as dumped. Fig. 3 is an enlarged end elevation of one corner of the car, and one of the hinges; and Fig. 4 is a sectional view on the line H of Fig. 3. Fig. 5 is a plan view of this corner of the car, partly in section; and Fig. 6 a perspective detail of the hinge member thereof. Fig. 7 is a perspective detail of the bolt detached from said hinge member; and Fig. 8 is a perspective detail of the lever for throwing said bolt. Fig. 9 is a horizontal section through the pivot of the arm, the eye at the inner end of the locking bolt, and the eccentric cam at the inner end of the hand lever. Fig. 10 is an enlarged horizontal section of the same part in a slightly moditied form, and Fig. 11 is an elevation of such part with the head of the pivot bolt removed. Fig. 12 is a similar elevation with the lever lock standing in a different position. Fig. 13 is an elevation of the eye at the inner end of the arm. Fig. 14: is a perspective detail of the lock proper.
The car truck T is mounted on wheels W and carries a central longitudinal bar L, to which at H is hinged the car body B having fixed ends E and movable sides S. The construction may follow that disclosed in my prior patent, or that of ordinary coal or ore cars commonly employed and which dump to either side, and the details, proportions, and materials of parts are not essential to the present invention.
At C, C are illustrated catches carried by the body B, and one of them engages one of the keepers K carried on the truck as set forth in my prior patent.
No novelty is claimed for the part-s thus far described.
When the car body B stands horizontal, as seen in Fig. 1, the sides rest against the beveled extremities e of the ends E, and the parts may be held in this position by chains as illustrated in Fig. 1 if desired, and especially if the car is to be subjected to rather rough usage. But it is the purpose of the present invention to provide means for locking the sides and their supporting elements in this position so that the chains may be omitted. When the body is tilted to the position shown in Fig. 2 it is held there by means of one of the catches engaging a keeper as set forth in my prior patent, but as the material within the car soon runs out of its body when the latter is thus tilted, the
'catch serves the purpose only of holding it against accidental righting.
Coming now to the details of the present invention, each side board is rigidly mounted at the outer end of a sector-shaped casting constructed as best seen in Fig. 6, and as the means for connecting the side boards S thereto are unimportant, I designate them broadly herein by the numeral 1. Such fastening device 1 is carried by an upright plate 2 which is cast over the outer edge of an are 3, and in a brace between the plate and are is disposed a pin or stud l to which one of the chains 5 may be hooked if desired. The are is supported by two arms 6 and 7 which converge toward and merge into a hub having an eye 8 disposed at the center of said arc, and this eye is pivotally mounted on a bolt 10 which is fixed through the car end Ea bushing 9 being by preference interposed between the bolt and the inner wall of the eye 8. The angle of the plate 2 (and therefore of the side board S) to the upper end of the are 3, and its disposition with reference to the pivot bolt 10 is such that as the side board starts upward from the posi ion shown in Figs. 1 and 3 it moves slightly away from the beveled end e of the end board E, and finally reaches the position shown at the right of Fig. 2.
In Fig. 7 is shown a bolt 11 having at its inner end an eye 12, its body along its outer side being provided with a stop 13 and the eye with another stop 141, the outer side of said body having a longitudinal rib 15, its outer end having a lug 16 with a downwardly facing shoulder 17, and the outer extremity of said body forming the tip 19 of the bolt, said tip being adapted to travel in a groove 20 in the radial inner face of the are 3 of the casting shown in Fig. 6. Pivoted at 21 to the lug 16 is a rod 22 whose lower end is pivoted at 23 on the truck T; and the length of the two rods is such that when the body 13 is level the parts stand as seen in Fig. 1, but when the body is tilted one rod draws downward on one bolt while the other rod pushes upward on the other bolt as seen in Fig. 2. The length of the groove 20 is such that the left hand bolt in Fig. 2 may be drawn downward within its are 3 as shown, but in tilting the body to the right as shown in that view it is obvious that the right hand rod 22 will raise the right hand bolt 11 so that the right hand casting and side board S will be elevated and the car body dumped at that side. This follows from the fact that when the body stands horizontal the tips 19 of the two bolts rest in the respective grooves 20 a slight distance beneath the inturned upper ends 2' of the plates 2 whereby a lost motion is permitted and either plate-extension 2 may move downward a trifle before it strikes the tip 19 of its bolt. Vith the latter projected as seen in Fig. 5 (by means yet to be described) the shoulder 17 of the lug 1G stands above a shoulder 3 formed in one wall of the groove 29 as seen in Fig. (3; and with these shoulders in contact as seen in Fig. 3, the lost motion just described is not permitted because, although there is nothing to prevent the remote side of the body moving downward, the contacting shoulders prevent either side of the body from moving upward. It follows therefore that if one bolt be retracted by any means, so that its shoulder 1? disengages the shoulder 3 in the runway or guide 20, that side of the body may ascend as seen in Fig. 3 and the other side will of course descend to dump the car. If both bolts should be retracted the car may be dumped to either side. The push rods 22 swing the bolts 11 as the car dumps, one bolt moving downward freely in the move 20 and the other moving upward and. carrying the casting with it.
In Fig. 8 is shown a lever 40 having on the inner side of its inner end a cam 41 pierced eccentrically with an eye 42 through which passes the main bolt 10, and the cam 41 is of a size to fit loosely within the eye 12 of the locking bolt 11. One side of the wall of this eye 12 is illustrated in Fig. 7 as having a socket or pocket 13 in which is a coiled expansive spring 44: pressing the heel end 45 of the lever 40 normally outward so that its body 410 and its handle end &6 are thrown normally inward, and if the back or inner side of said body is grooved longitudinally as shown at 7, this groove is thrown into normal engagement with the rib 15 on the bolt 11. The stops 13 and 1'71: above described, and well shown in Fig. 7, limit the throw of the lever 40 from one position as seen in Fig. 5 over to the opposite position as seen in Figs. 2 and 3. In its movement, it swings around the axis of the main bolt 10, and the cam face 11 engaging the eye 12 of the locking bolt 11 causes the latter to be projected or retracted in a manner which vill be clear. lVhen projected the shoulder 17 engages the shoulder 3 in a manner above described, and the dumping of the car in at least one direction is pro hibited; when retracted these shoulders come out of engaged position and the car may be dumped as already explained. An assembly of the cam, the eye 12, and the main bolt 10 is well illustrated in Fig. 9. -With this construction, when it is desired to dump the car it is obviously necessary for the operator to move the lever 40 on that side which will be the high side of the car, ,or move two such levers if this locking device is duplicated at the opposite end of the car shown in Figs. 1 and 2. Next he must of course unlatch at least one of the chains 5, or both chains if they are employed at both ends of the car. Then the latter may be dumped as seen in Fig. 2, and in the act of dumping the tip 19 of the locking bolt at the right side of the car travels upward in the groove 20 and strikes the plate-extension 2 so that the right hand side S is raised as will be clear. Vhen the parts are restored to a horizontal position the tip 19 of the left hand locking bolt travels upward whereas the right hand side moves downward until it rests in place and then the tip 19 of this locking bolt moves downward: when both tips come into proper position the right hand shoulders 17 and 3 engage and at this time the left hand lever can be swung back to its position against the stop 13 so as to project the left hand bolt 11 with its shoulder in engagement with the left hand shoulder 3. Thus the car body is locked against dumping in either direction. It quite obvious that if this mechanism is duplicated at the opposite end of a car. the proper bolt 11 must be retracted at that end also, and after dumping the proper bolt should be reset.
An amplification of my invention is illustrated on Sheet 3 of the drawings, and this consists in means for locking the lever 40 when it has been thrown to position to project the bolt 11 which, as above described, locks the car against dumping. While it is improbable it is yet possible that vibration might throw one of the levers 10 from its position where the parts are looked, over onto the opposite stop 14 where the parts are unlocked, with the result that the car could and possibly would dump automatically and undesirably. Also it is obvious that the lever could be so thrown by a person who was maliciously inclined. Hence the provision of a lever-lock now to be described. The use of the spring 4st and the rib 15 engaging the groove 17 of the lever 40 holds the latter in active position only by friction. I might duplicate this arrangement in connection with the lever look below, although I have shown on Sheet 3 of the drawing another form of tension spring for holding the rib engaged with the groove. It is even possible that the spring, the rib, and the groove could be entirely omitted when the lever lock is employed. J ournaled through the cam or eccentric 41, parallel with the main bolt 10, is a rock shaft 50 which in the present instance is illustrated as having a triangular front end 51 adapted to be engaged by a peculiar shaped key, and projecting radially from the body of said shaft is a tumbler 52 adapted to be housed within a recess 53 in the cam when the shaft 50 is turned in one direction, or adapted to be thrown outward into engagement with a recess 54 in the inner wall of the eye 12 of the locking bolt if the shaft 50 be turned in the opposite directionhere the left. The shaft has flattened sides 56 engaged by a spring 57 to hold it yieldingly in various positions. Assuming now that this lever lock is set as last described, if a miscreant should endeavor to throw the lever 40 he grasps the handle end 46 and seeks to lift it, and immediately the outer end of the tumbler 52 strikes the flat upper end of the recess 54 and he finds that the lever cannot be moved. Having no key which will engage the front end 51 of the rock shaft 50,
he cannot unlock the device and therefore he cannot throw the lever. On the other hand, when it is desired to dump the car, a person in authority having the proper keycan turn the rock shaft and in so doing he throws the tumbler out of engagementwith the recess 54 and houses it within the recess 53 within the cam, after which he may throw the lever and the cam turns in the eye 12 and carries the tumbler with it. I give this explanation and illustration as typical only of one form of lever lock which may Well be employed in this connection, but do not wish to be limited thereto. Sheet 3 of the drawings also shows how the coiled expansive spring 44 located within the pocket 43 may be replaced by a coiled expansive spring 64: surrounding the main bolt 10 under its head 10 and located within a pocket 63 formed in the outer face of the cam; and if this construction be adopted it is clear that before the lever 40 can be thrown it will have to be bodily drawn outward on the main bolt so that its groove 47 will disengage the rib 15, whereas with the construction shown in Figs. 7 and 8 the lever 40 need be sprung outward at its handle end only and for a distance sufficient to disengage said groove from the rib. As above suggested, this detail also is unimportant, and either described form or any equivalent form may be employed. In fact, in the simpler and cheaper types of this device it might be possible to entirely omit the lever lock and either form of spring 4 1 or 64, as well as the groove and rib constituting the latching means for holding the lever frictionally in active position, and rely on the weight of said lever to remain upon the stop 13.
The important feature of the present improvement over my prior patent is the provision of a locking bolt 11 having a shoulder 17 adapted to engage a shoulder 3 in the runway or groove 20 when said bolt is pro jected, such engagement preventing the elevation of this side of the car body B; therefore the car cannot be dumped to the opposite side, although it is yet possible to dump it on this side. The fact that the distance between said shoulder 3 and the overhanging plate 2 is greater than the height of the bolt tip 19, gives a certain degree of lost rnotion which may be useful if the parts are made of rough castings and do not fit each other accurately. In the act of dumping the car this lost motion occurs while the side being dumped is descending slightly, and therefore the side board S does notstart upward relatively to this side immediately the latter begins to descend. The result is that some of the ore, coal, or other material with which the car is loaded falls against or starts toward this side board, and when the latter rises the load dumps with a rush and its travel toward that side of the car automatically assists in the act of dumping the latter completely.
