DUMP CAR FOR TOY RAILROADS Application July 8, 1939, Serial No. 283,354
8 Claims.
This invention relates to dump cars, and more particularly to a dump car for toy railroads.
The primary object of my invention is to generally improve toy dump cars. A more particular object is to provide an improved mounting for affording tipping of a dump body, said mounting being so devised that, on the one hand, the dump body tends to gravitationally remain in upright position, yet, on the other hand, is easily dumped, and when dumped discharges its contents well to the side of the car and the track bearing the same.
A further object is to provide such a dump car with means affording dumping under remote control, this arrangement being particularly applicable to toy railroads of the electrically operated type.
To the accomplishment of the foregoing general and other more particular objects, which will hereinafter appear, my invention consists in the dump car elements and their relation one to the other, as hereinafter are more particularly described in the specificationand sought to be defined in the claims. The specification is accompanied by a drawing in which:
Fig. l is a partially sectioned side elevation of a dump car embodying features of my invention; Fig. 2 is a partially sectioned end elevation of the same with the body in upright position, this section being taken in the plane of the line 2-2 of Fig. 1;
v Fig. 3 is an end elevation of the car with the body in tilted position;
Fig. 4 is a fragmentary section explanatory of a constructional detail of the car;
Fig. 5 is a plan view of a small portion of a track section and shows the provision of a fourth rail or ramp at the dumping station; and
Fig. 6 is a schematic wiring diagram explanatory of the invention. 7
Referring to the drawing, and more particularly to Figs. 1 through 4, the dump car comprises a generally flat topped car body or chassis I2, and a dump body l4 pivotally mounted thereon. The dump body is carried at one end by crossed arms I5 and I8, and at the other end by crossed arms and 22. The upper ends of the crossed arms are pivotally secured to the dump body l4, while the lower ends of the crossed arms are pivotally mounted on the chassis l2. the dump body is well above the center of gravity of the body, and the body therefore tends of itself to remain in the upright position shown in Figs. 1 and 2. However, if the body is tilted to one side it is guided to a position such as that The connection to indicated in Fig. 3, thus bringing the edge 24 of the car outside the chassis and the track rails. In other words, the body is moved sidewardly, as well as tilted, thus discharging its contents safely at the side of the car and track.
In order to provide a smooth working and stable support for the dump body and to assure parallel movement at both ends of the body, the arms l6 and 20 are preferably connected together for simultaneous movement, and similarly the arms l8 and 22 are preferably connected together for simultaneous movement. For this purpose the arms l6 and 20 are connected at their lower ends to a shaft 2t extending lengthwise of the chassis, and the arms l8 and 22 are'connected at their lower ends to a second shaft 28 extending lengthwise of the chassis.
For the sake of economy in manufacture, the arms may be made of stiff round wire, and may be formed integrally with the shafts 26 and 28. Specifically, a single piece of'wire is bent to form an inturned end 31! at the upper end of arm l6, then the arm It, then the longitudinally extending shaft 26, and is then bent upwardly to form the opposite arm 20, and is finally bent inwardly to form the inturned end 32. The inturned ends and 32 are received in mating holes in the end walls of the car body. Similarly, a single piece of wire is bent to form the arms [8 and 22, together with the longitudinally extending shaft 28 and the inturned ends at the upper extremities of the arms.
As a simple and convenient way of mounting the shafts 26 and 28 in position, and at the same time desirably concealing the same from view, these shafts are preferably located between two horizontal plates forming a part of the chassis l2. Specifically, the chassis is made up of a flat topped piece of sheet metal 34 (Fig. 4), the
side edges of which are bent downwardly to form the skirts or walls 36 (and the ends of which are bent downwardly to form the end walls 38, Figs. 1 and 3). When, as in the present case, the car is provided with only four wheels (instead of two trucks with four wheels each) the axles 40 for wheels # 22 may be received directly in the side walls 36, and these may be suitably shaped and embossed to simulate car bearings.
A second piece of sheet metal is upwardly dished to form a flat top wall 44 (Fig. 4), and a narrow peripheral edge 46 extending entirely therearound. The end parts of the peripheral edge 46 are notched upwardly slightly from the open bottom edge, as is indicated at 48, thereby forming bearings to receive the longitudinally extending shafts. The upper member 44 is secured to the lower member 34 by appropriate bent tongue and slot connections, as is indicated at 50 in Fig. 4. It will be understood that to assemble the parts it is merely necessary to place the shafts 26 and 28 on the Wall 34 and to cover the same by means of the cover plate 44, thereafter bending the tongues 50 in order to lock the plates of the chassis together. The body l4 may be applied to the crossed arms by simply springing the arms apart enough to permit the inturned upper ends thereof to be received in the holes in the ends of the dump body.
The end walls 38 of the chassis may be slotted, as is indicated at 52 in Fig. 3, thereby providing an opening through which a coupling bar 54 is received. The end of coupling bar 54 has a tongue which is bent downwardly at 56, this being adapted to be received in a mating slot cut in the top of another coupling bar, so that successive cars may be coupled together. The coupling bars are pivoted on the bottom wall of the chassis in accordance with conventional practice.
The dump body I4 is pressed up out of sheet metal, and in the present case is formed of a single piece of sheet metal. The peripheral edge at the open top of the body is preferably curled, as shown, to form a rounded protective edge which also functions to stiffen the dump body.
As so far described, the car may be used with either a mechanical or an electrical railroad, and the body may be tipped to either side, it being necessary to physically push the dump body to one side or the other in order to move it from upright position to dumping position. The specific car here shown is, however, provided with additional means for remote control dumping of the car. Referring to the drawing, it will be seen that the car is provided at its bottom with a solenoid 60 arranged with its axis extending transversely of the car body. An armature core 62 is reciprocable within solenoid 60. It is normally moved outwardly by a comparatively light coiled spring 64 surrounding the armature core. The
outer end of the core 62 is appropriately connected to a crank mounted on one of the connecting shafts; in this case, the shaft 28. This is most simply done by bending an intermediate part of shaft 28 downwardly to form a crank, as is indicated at 66. The crank 66 is received within a loop 68 secured to the end of core 62 The loop 68 is so arranged as to permit of relative vertical movement of crank 66 and the core, thus accommodating changes in elevation due to angularity of the crank. In other words, the member 68 functions to form a vertical slot at the end of the core, in which slot the crank 66 is received.
It Will be evident that in Fig. 2, the core 62 is in its outward position, and the dump body [4 is in upright position. However, upon energization of the solenoid 60 the core 62 is drawn into the solenoid, thus changing the parts from the position shown in Fig. 2 to that shown in Fig. 3. At this time the crank 66 has been swung in a counter-clockwise direction, thereby swinging the arms I8 and 22 from the position shown in Fig. 2 to that shown in Fig. 3, thereby dumping the car body.
When the body is tilted to the position shown in Fig. 3, the arm I8 is within the bend at the upper end of the arm I 6, and the latter therefore acts as a motion limit means to prevent further tilting of the body beyond the position shown.
In order to energize the solenoid 66 when desired, the car is provided with an insulatedly mounted contact shoe 10, this contact shoe being adapted to ride on a suitable length of fourth rail or ramp 12. Referring to Fig. 6, it will be seen that the track is made up of outer or service rails '14 and a third or power rail 16. These are connected to a transformer 18 at the binding posts 80. The potential across binding posts 86 may be varied, as by means of a speed control handle 62. The ramp 12 may be comparatively short in length, it being located at a suitable dumping station where it is desired to dump the contents of the cars. Ramp I2 is engaged by contact shoe l0, and this in turn is connected to solenoid 60. The opposite terminal of the solenoid is connected to ground, the circuit being completed through axle 40, wheels 42, service rails 14, and a wire 84 leading back to binding post 86. It is customary to provide a toy transformer, such as the transformer 18, with four terminals, two of which, in this case, the terminals 80, receive a variable potential for supply to the track, while the other two, in this case, the terminals 86, receive a constant potential for energizing accessories. Thus the ramp [2 may be energized even when the power supply to the track is cut off in order to bring the car to rest at the ramp.
The supply of current to ramp 12 is controlled by suitable switch, preferably a push-button 90 which is normally open-circuited. In this way the ramp 12 is normally dead, and the train may run around the track without dumping the dump car. However, by pressing the button 90 the ramp 12 is supplied with power, and the solenoid 60 is energized to dump the car. Preferably, the car is stopped during the dumping operation, but this is not essential, and the car may be dumped while under motion by simply pressing the button 90 and holding it pressed as the train passes the dumping station.
The ramp 12 may be constructed in a variety of ways. In the present case it is formed of sheet metal and is mounted on two or more pieces of insulation, such as that shown in 92 of Fig. 5. This piece of insulation is cut away at 94 to receive the conventional tie 96 of one of the track sections. In this way the ramp may be located wherever desired around the toy railroad track. The ramp 12 is provided with suitable means, in this case, a clip 98 which receives the end of conductor I00 leading to the push-button 90. The ramp [2 is preferably made somewhat higher than the rails 14 and 16, so that there will be no accidental engagement of the contact shoe 16 with the rails, as when crossing a switch or crossover, or the like.
The wall 34 of the chassis is preferably cut away at the center of the car in order to clear the crank 66. This is not necessary when the car is used for manual dumping, or for action by an external track-side dumping mechanism, such as is disclosed in my co-pending companion application, Serial Number 283,353, filed concurrently herewith. The solenoid 60 is received in a generally U-shaped frame I02 extending transversely of the car, the upper ends of the U-shaped frame being secured in position by appropriately bent tongue connections I04. It will be noted that in the present case these are secured through the top wall 44. This has the advantage of elevating the solenoid and thereby providing ample clearance between the bottom of the solenoid and the track. In such case the entire local area of wall 34 is cut away at the solenoid, thus clearing not only the crank 66, but also the solenoid mounting. The contact shoe it is secured to a piece of insulation H36 (Fig. 2) which in turn is mounted on one upright wall of the U-shaped mounting Hi2, as by means of bent tongue connections IE8. These tongues bear on the ends of the insulation member I96 and do not touch the contact shoe H3, this being, of course, insulatedly mounted and connected by a piece of wire to one end of the solenoid winding.
It is believed that the construction and method of assembly and operation of my improved dump car will be apparent from the foregoing detailed description. It will be understood that the crossed arm mounting for'the dump body may be used without arranging the car for remote control, in which case the solenoid mechanism and the track-side ramp may be eliminated. Also the crank 66 on shaft 28 may be eliminated, in which case the bottom wall 34 of the chassis may be left intact, the shafts 26 and 28 both being straight and both being concealed between continuous top wall M and bottom wall 3 as is shown in Fig. 4.
It will therefore be understood that while I have shown and described my invention in a preferred form, many changes and modifications may be made in the structure disclosed without departing from the spirit of the invention assought to be defined in the following claims,
