Crosman, Bloomfield, N.J., assignors, by mesne assignments, to The Lionel Toy Corporation, Wilmington, Del., a corporation of Delaware Filed Feb. 14, 1962, Ser. No. 173,298 15 Claims. (Cl. 214-44) This invention relates to toy railway systems and to toy railway cars, particularly to lightweight toy cars, such as may be used in H0 gauge and similar sizes. The invention is to be described in the embodiment of an automatic milk car, but it is to be understood that the principle of the unloading mechanism as described in the appended claims, is suitable for the unloading of items other than milk cans. The operation of the unloading mechanism involves the use of actuator means, such as described in the co pending application, Serial No. 107,- 357, filed May 3, 1961, now Patent No. 3,125,668.

In the above-named patent it has been pointed out that the basic problem in providing a workable toy railway unloading car in the smaller gauges arises due to the lightweight of such cars. Therefore, the car according to the present invention is provided with means by the aid of which it is attached to a fixed unloading platform, preventing the derailment of the car during the operation of the unloading mechanism.

Accordingly, it is an object of the present invention to provide an unloading car in which the weight problem of light cars is overcome and it can be used for automatic unloading operations and the like. Another object of the invention is to provide a railway car which retains its realistic appearance although provided with stabilizer means to insure an underailing performance during the operation of the car.

It is another object of the present invention to provide an unloading car for the continuous unloading of a plurality of simulated freight objects onto an unloading platform.

Yet another object of the invention is to provide an unloading mechanism which is simple in construction and lends itself to ready assembly during the manufacturing operation.

Another object of the invention is to provide an automatic milk car for the unloading of a plurality of milk cans onto an unloading platform.

In accordance with the objects of the invention, the specific embodiment of the invention presently to be described, includes a car platform resting on a conventional toy railroad carriage. The car platform provides laterally extending projections or stabilizers, similar to the ones described in the above-named patent, which become positioned beneath the edge of the unloading platform when the car pulls up to the unloading platform. An actuating level: operates an unloading actuator depending from the bottom side of the car platform,-resulting in substantially three operating sequences. The first sequence involves the rotation of a revolver goods replenisher, which in this instance, supplies subsequent milk cans for the unloading operation. According to the second sequence, a milk can supplied during an earlier actuation is brought onto the unloading platform. The third sequence involves the opening of the car door for providing a path for the unloading mechanism. When the actuating arm or lever is withdrawn, the unloading actuator returns to its initial position, whereby a milk can, supplied in the previous operation and placed into a ready-position falls into place for subsequent unloading, while the unloading mechanism retracts, functioning in reverse and the doors close. The holding capacity of the revolver goods replenisher and the desire of the op 3,231,108 Patented Jan. 25, 1966 erator will determine the number of cans to 'be unloaded. E-ach unloading operation requires a separate actuation of the actuating lever. I

Other objects and advantages of the invention will be better understood from the following detailed descrip, tion of the specific embodiment of the invention, together with the drawings, wherein:

FIG. 1 is a top plan view partially broken away and partially in section of a milk car and an actuator-unloading platform combination of one embodiment;

FIG. 2 is a sectional-elevational view along line 22 of FIG. 1;

FIG. 3 is a section taken along line 3-3 of FIG. 2;

FIG. 4 is a section taken along line 4-4 of FIG. 2;

FIG. 5 shows an enlarged view of the center portion of FIG. 4 when the unloading actuator is depressed;

FIG. 6 is a section taken along line 6-6 of FIG. 2;

FIG. 7 shows the elements of FIG. 6 in an actuated position;

FIG. 8 shows part of the unloading platform during the operation of the car;

FIG. 9 is a sectional-elevation-al view of the hinge arrangement; and

FIG. 10 is a section taken along line 1010 of FIG. 9.

The unloading platform shown for the operation of the milk car is the same as in our above-mentioned patent, except for a magnet M as best shown in FIG. 1. This magnet is attached at a suitable unloading location to the underside of the unloading platform, for a purpose to be described later.

In FIG. 1, a milk car 1 is shown on tracks 2 beside an unloading platform and actuator combination 4. The tracks 2 with their ties 6 form part of the unloading platform-actuator combination 4. As also shown in FIG. 1, a reloading opening 8 for milk cans 10 (FIG. 2) is located at the roof of a car housing 12. The opening 8 is covered with a cover 14, which when closed is flush with the roof of the housing 12. The cover14 pivots around a pin 16 by means of an extending portion 18 of the cover 14, and a fiat spring 20 secured to the inside of body 12 by rivets 22 assures that the cover 14 remains either in its entirely open or entirely shut position. A revolver-goods-replenisher, or magazine 24 is located directly under the opening 8. The magazine 24 has holes 26 distributed along its periphery, and ratchet teeth 28 are formed in its side, the number of these teeth end of the connecting rod 44 is lodged in an oval cutout 46 of a connecting member 48.- A tensioning spring 50 is attached at its one end to the bent portion of the connecting rod 44 lodged in the cutout 46 and at its other end to a hook 52 formed on the connecting member 48. The spring 50 pulls connecting rod 44 and unloading actuator 34 to one extremity of the cutout 46, so that when the unloading actuator is not depressed back lash and noise that would' result from backlash of the uncomplicatedconstruction is avoided; and when the unloading-actuator 34 is depressed, the rod 44 travels to the other extremity of the cutout 46, thus giving some a retraction spring 56 exerting a pressure thereon, to keep the connecting member 48 in its clockwise retracted position. The lower end 58 of spring 56 presses against an upstanding lug. 60 formed from the car platform 38. A Wing 61 of a principal frame member 62 projects over the free end of pin '53, preventing connecting member 48 and spring 56 from falling off the pin.

As best shown in FIGS. 4 and 6, the connecting member 48 is bent at 64 and terminates in a nose portion 66. Also shown in FIG. 7, the nose portion 66 engages a hole 68 in a pressure member 70. The pressure memher is pivoted at 72 to a pivot lever 74. The pivot lever 74 has an upstanding shoulder 76 against which pressure member 70 can press when the mechanism is retracting due to the bias of the spring 56. The pivot lever 74 is pivotally supported on the car platform 38 by means of a pin 78, at its lower end being peened to the car platform. A limiting stop is provided for the pivot lever 74 by means of an upstanding flange 79, for limiting its retractive travel, to thus prevent the nose portion 66 to slide out of hole 68. A Wing 80 of the principal frame member 62 secures a pivoting sleeve portion 82 of pivot lever 74 on pin 78.

Integrally attached to the other end of the pivot lever 74 is a principal unloading member 84, having its free end formed to define a U-shaped recess 86. A platform 88 is provided at the side of member 84 with a man 90 being attached thereto for a realistic appearance.

A free end 92 of pressure member 719 is located below the end of the U-shaped recess 86 opposite platform 88. The free end 92 is shaped in the form of an upstanding vertical wall portion, and is adapted to diminish the width of the U shaped recess 86 in the principal unloading member 84.

A pawl member 94, adapted to engage ratchet teeth 28 on magazine 24 is pivotally attached to the pivot lever 74, at 72. The ratchet engaging portion of pawl member 94 is maintained by spring 96 (FIG. 2) against a ratchet 28 of the magazine 24. An upstanding flange 97, integral with pivot lever 74, supports one end of the spring 96. The principal frame member 62 has a flat top portion 95a (FIG. upon which the magazine 24 can rotate. An upstanding peg'98, integral with the flat top 96a serves as an axle for the magazine 24, which is attached to it by means of a securing spider 100. Notches 102 (FIGS. 2-and 3) are formed within the bottom edge of the magazine 24 having onewall of said notches slanted while the other wall is substantially vertical. A fixed detent protrusion 104 is formed integral with the flat top portion 96a, and shaped to fit the notches 102. When the magazine rotates, portions of it, intermediate the notches 102, ride over the fixed detent protrusion 104 and the revolver rotates in an indexing manner from notch to notch.

Flat top 96a forms the bottom of holes 26, so that the milk cans 10, which are loaded in holes 26, slide over the flat top 96a. A hole 106 (FIGS. 3 and 5), being of a slightly larger diameter at its upper end than the holes 26, is provided in a sleeve 108 forming part of the principal frame member 62 for removing a milk can at the time from the hole 26 overriding the hole 106 (FIG. 2). This hole 106 is in line with hole 26 and serves to channel the dropping milk cans to eventuall'y'come to rest within the U-shaped recess 86 of principal unloading member 84. The principal frame 62 is firmly attached to car platform 38 at various locations 110.

'In FIGS. 9 and 10 the hinge arrangement of the door is shown. The car body 12 consists of a molded plastic shell, in its details approximating the appearance of a real railroad car. A pair'of doors'is provided on both sides of body 12, but'thedoors areoperable only on one side. The inoperable doors (not shown) are molded in shell 12 only for appearance. The hinge construction of door 114 is an inverted'mirror-image of the hinge construction on door 112, therefore, in FIGS. 9 and 10 reference is made only to door 112. The left hand pivoting side of door 112 is formed with two protruding pins, an upper pin 116 and a lower pin 118. The pin 116 is formed to be longer than pin 118 so as to accommodate a door closing spring 120. The pins 116 and 118 are inserted in grooves 122 and 124 respectively, formed in the car body 12, and the doors are held in place by overhanging flange strips 126 and 128. These overhanging flange strips are anchored in the body 12 through holes 130. Spring is biased to keep the door 112 closed.

The door 112 is molded to include a simulated latch member having a protruding portion 132 (FIGS. 1, 3, 4 and 6-8). An inward protruding member 134 is also molded onto the door 112 (FIGS. 3, 6 and 7), to keep the can 10 located within the U-shaped recess 86 when the door 112 is closed.

Laterally extending stabilizers are provided integral with car platform 38. The stabilizers 140 are adapted to lodge under the'overhanging edge 142 (FIG. 3) of the unloading platform 4 so that when actuating lever 32 presses against unloading actuator 34 the stabilizers 149 Will lean against the overhanging edge '142 and keep the car 1 from tilting and maintaining it on the tracks 2.

Operation of the car When the train pulls alongside the unloading platform 4, the milk car 1 is stopped so that its doors 112 and 114 are approximately in line with the magnet M of the platform 4. At the same time, laterally extending stabilizers 140 are disposed under the overhanging edge 142 of the unloading platform 4.

The magazine 24 was previously loaded with cans 10 by opening, the lid 14 in the body 12. After the loading operation was completed, lid 14. was closed.

When'the unloading of one, or more cans onto the unloading platform 4 is desired, the solenoid 30 is energized resulting in a sudden upward move of actuating lever 32. This move will result in a series of sequences, taking place substantially simultaneously. As the unloading actuator 34 pivots around its hinge 36 (FIG. 2), the interior mechanism of milk car 1 will change from the position shown in FIG. 6 to the position shown in FIG. 7. The connecting rod 44 is pulled leftwards, pulling the connecting member 48 leftwards with it, causing its nose portion 66 to move forward. This movement of the connecting member 48 occurs against the bias of the retracting spring 56.

The nose portion 66, at its free end being located in hole 68, by its forward movement pushes the pressure member 70 forward. Since the pressure member pivots at 72, the diminishing of the width of the U-shaped recess 86 Will result. This narrowing of the recess 86 continues until the end 92 of pressure member 70 comes into contact withthe milk can 10 pressing it firmly within the recess 86. Continued pressure transmitted from the unloading actua-tor 34'causes the pivot lever 74 with all'its associated and integral portions to move forward. The rounded-off portions of pivot lever 74 forming the forklike shape that defines U-shaped recess 88, push against the inside of doors 1'12 and 114 and open them under continued forward movement.

Since the upward "movement of actuating arm 32 is quite sudden, care has to be taken that the above-mentioned sequences do not-cause the milk can 1010 be swung out onto or past the platform With too much force. Since the pressure member 70 applies continuous pressure against the can 10, in effect pressing it against the wall of U-shaped recess 86 adjacent to platform 88', the can 12 is held captive within recess86.

Simultaneously with the forward movement of pivot lever 74, the pawl 94 tends to grasp the recessed portion of the ratchet 28 and cause the magazine 24 to make one indexed rotation ina counterclockwise direction. During this rotation, the fixed detent protrusion 1'04 releases the corresponding notch 102 and during the rotation of the magazine the-fixed detentwillride over a smooth edge portion between adjoining notches 102. When the forward movement of pivot lever 74 and pawl 94 coupled thereto ends, a subsequent notch 102 will nest over fixed detent 104. As a result of this one indexed revolving motion, another hole 26 with another milk can will be positioned over hole 106 (FIGS. 2 and 5). Due to the eflect of gravity, the milk can 10 will drop through hole 106and guided by conical sleeve 108 and come to rest on a fiat portion of the extended pivot lever 74. This fiat portion is located under the hole 106 when the pivot lever is extended and upon retraction, the can 10 will drop into the recess 86. The conical design of hole 106 in sleeve 108 will assure that the can 10 from hole 26 will always be guided into the hole 106.

When the pivot lever 74, with the milk can 10 seated firmly in its U-shaped recess 86 by the pressure of pres-v sure member 70, reaches its extreme outward position as shown in FIG. 7, the can 10 reaches the attracting field of the magnet M which will pull the can out of the recess 86 over the magnet itself on the unloading platform 4 as soon as the pressure applied by the free end 92 of pressure member 70 is released.

As soon as the solenoid 30 is de-energized, the actuating arm 32 is lowered and the retractive sequence of the mechanism starts. The pressure applied against unloading actuator 34 is released and the bias of spring 56 pulls the connecting member 48 now in the opposite direction. The bias of spring 56 pulls the unloading actuator through connecting rod 44 into its initial, original position. The mechanism goes through the same sequence as outlined above, only in the opposite, retractive direction. The pawl member 94 is maintained by spring 96 constantly against the ratchet surface of revolver goods replenisher 24. During the return motion, the end of the pawl 94 rides over a ratchet tooth surface 28 and in the extreme return position becomes lodged in another of the ratchet tooth recesses. The elongated nose portion 66 of the returning connecting member 48 pulls against the rear wall of hole 68 of the pressure member 70 and causes it in the first moment of retraction to release its pressure, and the force of the magnet M pulls a can 10 out of the recess 86 and disposes it on the platform 4.

As the pivot lever 74 retracts, the spring loaded doors 112 and 114 begin to close along with its retraction. During the closing movement of the doors 112 and 114, the protruding portion 132 on door 112 pushes the last unloaded can aside, as shown in FIG. 8, to make room for subsequent cans to be unloaded.

The milk can dropped through sleeve 108 during the can unloading sequences rides over the flat portion of the retracting pivot lever 74 until the recess 86 is located under hole 108, at which time the can will drop into the recess 86. At this time the mechanism is ready for subsequent unloading sequences, until the supply of milk cans 10 in the magazine 24 is exhausted, at which time it can be reloaded again.

The cooperation of the magnet M and the protruding portion 132 of door 112 with the cans 10 being unloaded assures that the cans are stacked in an orderly manner, close to each other over the magnetized portion of unloading platform 4.
