DISCHARGE AND PICKUP APPARATUS FOR TRAVELING TOY RAILWAY CARS Filed Feb. 24, 1941 2 Sheets-Sheet 2 Patented Aug. 29, 1944 DISCHARGE AND PICKUP APPARATUS FOR TRAVELING TOY RAILWAY CARS Richard G. Smith, Amsterdam, N. Y. Application February 24, 1941, Serial No. 380,340

19 Claims.

This invention relates to toy mail or baggage cars that are self-loading and self-unloading while traveling along a toy track as part of a toy train.

Toy mail cars equipped with a projecting arm adapted to scoop ofi from a track-side supporting structure some loadable toy article, simulating for instance a full mail bag, have heretofore been known in the art. Also, mail ejecting as well as mail pick-up apparatus adapted to operate without stopping the train is commonly used in real railroad operation but only in forms of apparatus and mechanism which are far too complicated to be duplicated in miniature size for use in toy trains.

An object of this invention is to equip a toy mail car or baggage car with an extremely simple and reliably operating device capable of automatically discharging from such car while the car travels along its track an unloadable article representing say a mail bag, and instantly thereafter automatically picking off from some trackside stationary means of support a different or loadable toy article or mail bag and whisking the latter into the interior of the car in place of the mail bag which just previously has been ejected, all while the car continues its full speed of travel.

A further object is so to simplify a toy working mechanism for this purpose that it may make use of the same movable structure, carried by the toy car, both for discharging the first mail bag and for taking on the second or different mail bag as described.

A further object is to produce the above described functions of automatic mail bag discharge and pick-up preferably under the optional control of the operator of the electric toy railway system and preferably by means of an electrical controller which may be stationed remotely from the point in the track system at which the automatic exchange of toy mail bags is to take place.

A further object is to orient the toy mail bag. when taken into the toy mail car in such manner that this same mail bag subsequently may automatically be ejected at the same or at some other mail'exchange station when the toy train next passes such station.

A still further object is to produce automatic movement of a toy mail bag actuator relative to the car by which it is carried, and then to combine such relative movement coordinately with the travel of the car as a means of scooping off and transferring to the interior of the mail car that toy mail bag or other article which is presentedto the toy train by the track-side article support.

These and other objects of theinvention will be more clearly understood from the following description of a preferred embodiment of the invention in which description reference is made to the accompanying drawings, wherein:

Fig. 1 is an isometric view of a portion of a toy mail car carrying mail bag exchange apparatus incorporating the present improvements, together with sections of a toy railroad track and a track-side standpost.

Fig. 2 shows the take-on arm of the apparatus in Fig. l arrived at and acting on the post supported mail bag.

Fig. 3 is a plan view of the parts appearing in Fig. 1 with roof of the mail car broken away showing the toy mail bag in its compartment in the traveling car about to be automatically discharged therefrom at the track-side.

Fig. 4 is similar to Fig. 3 showing the mail bag of Fig. 3 ejected from the car and showing the exchange mechanism as it is positioned just before engaging with the post supported mail bag which is next to be taken into the mail car.

Fig. 5 is a fragmentary view taken in section on the planes 555 in Fig. 4 looking in the direction of the arrows.

Fig. 6 is a fragmentary view showing the hinge construction of Fig. 5 enlarged and in section on plane 66 in Fig. 4.

The chassis including floor'5 of toy car I0 rides on trucks, as 6, and supports a hollow car body having a roof 9 and fashioned to resemble a mail car or baggage car of a real railroad train. Car side 8 contains an aperture 4 likened to the doorway of a mail car just inside of which a segmental article storing or article repository compartment is walled partly about or bordered by structure including the fixed upright arcuately curved partition I I which assists in orienting the car carried toy article or insuring its retention in position to be discharged automatically from the car. Remaining sides of this compartment are walled off in Fig. 3 by the 'angularly related panel forming vanes or arms ofa swingable bell crank structure I3, comprising an oscillatory device of unitary nature one of whose arms [4, hereinafter sometimes referred to as the take-on arm, is given a hook-likeformation and is rigid with the swingable gate-like vane sweeps back and forth crosswise of the car over floor 5 between its positions in Figs. 3 and 4. Both arm l4 and vane l2 may be made from thin, light weight, sheet material. gvane I2 further is l2 which.

provided with spaced upper and lower backturned ears l5, l6, carrying a vertical crank pin H. The bell crank structure or double armed gate [3 swings freely on a vertical hinge pin I8 by means of hinge lugs 22, 22 turned over from the metal of arm I4 and this pin is held jointly in an upper flange l9 and in a flange l9 spaced therebelow on a mechanism frame 2| which has its base 29 fixed to the chassis or floor of the mail car. This establishes a vertical pivotal bearing axis about which the oscillatory device or bell crank structure is swingable as a unit. Frame 2| further includes two holding tabs 23 and 24 bent up from base plate to which tabs the curved partition II is spot welded or otherwise fixed. Mechanism frame 2| further has the upright side wall 25 which carries the above mentioned flanges I 9, l9. On this side wall is mounted by screws 26 an electromagnet which may take the form of a solenoid 2'! having the usual hollow core in which freely slides horizontally a magnet plunger 28. A connecting rod 29 whose looped end loosely and pivotally engages with crank pin I! may be fixed in plunger 29 "to slide longitudinally therewith. A spring 30 loosely coiled about plunger 28 is compressed between the end of the solenoid and a thrust washer 3i retained on the end of plunger 28 by peaning over the reduced terminal portion of the plunger. Spring 39 constantly urges plunger 28 toward the right into its normal position shown in Fig. 3 whenever solenoid 27 is electrically deenergized. The insulated winding of conductive wire of the solenoid terminates at one end in a lead 32 which connects electrically with a cats whisker 33, or flexible current collector shoe, projecting sidewise from the car at a low point and insulated from all metallic structure of the car by a mounting plate 34 of insulating material. The other end of the solenoid winding is grounded to the car chassis 5 and therefore is constantly in electrical connection through wheels 1 with the traction rail 35 which in usual manner may be supported upon sleepers 36.

In Figs. 3, 4 and 5, 31 represents the opposite traction rail or power rail of a two track electric track, while 38 represents the third rail or power rail, of a three-rail toy track system. It will be understood that traction rail 35 connects to the negative or return circuit binding post of a battery or toy transformer (not shown) so that a fourth rail or auxiliary rail 39 may be provided at the track side in insulated relation to rail 35 in position to be momentarily contacted by the cats whisker or current collector shoe 33 just as the toy mail car approaches stand post 49 which is stationed beside the track.

This stand post may be held upright by riveting its lower end to a channel iron 4| which is nested in and projects beyond one of the sleepers 36. A bracket 42 is carried in an elevated position on post in the form of an angle bar provided with the mounting hub 43 which is assembled rigidly with post 40 by being pressed tightly onto a section of the latter roughened by knurling. Bracket 42 carries a tongue 44 which will preferably be given an upward tilt and from which is suspended a toy mail bag 45 having loops 46 fixed in its ends for this purpose. Thus constructed the stand post and bracket may be referred to as a track-side article let-01f support or rest.

In operation a toy train will be impelled along the track incorporating a mail car such as In containing a mail bag as shown in Fig. 3. Shortly before reaching the stand post 49, cat's whisker 33 rides into contact with the top edge of fourth rail 39 and thereby energizes solenoid 2'! drawing plunger 28 and thrust rod 29 smartly to the left. This swings the bell crank or double armed gate l3 counterclockwise in Figs. 1 and 4. In this movement of the gate, ejector vane or article unloader l2 discharges mail bag 41 through the doorway 4 in the side of the mail car and onto the ground or table top alongside the fourth or auxiliary power rail 39 as indicated in Fig. 4. Immediately thereafter takeon or articleloader arm M of gate l3, riding with the mail car, advances into engagement with the toy mail bag 45 which is suspended from bracket 42 and sweeps the latter forward and abruptly inward toward the car whereby the mail bag is whisked into the interior of the mail car through doorway 4 and is penned in its position shown in Fig. 3 by the partition II and arms I2, [4 of gate l3. Arm I4 then forms a barrier across the doorway preventing the loaded mail bag from falling out of the car and the two crank arms I2, 13 then straddle the loaded article at the same time cooperating with partition H to more fully enclose the article containing compartment, This loading action results at least in part from the sudden deenergization of solenoid 21 when cats whisker 33 runs off from the end of the short length of auxiliary rail 39 thus causing deenergization of the solenoid and permitting .spring 30 instantaneously to snap the bell crank structure l3 clockwise from its position in Fig. 4 to its position in Fig. 3 just as hook [4 contacts with the mail bag 45 which is to be taken off from post 40. It will help to make clear that different mail bags have actually been exchanged if the imitative toy bag bodies 45 and 41 are colored to contrast or made of radically difierent shape or size so that the unloaded bag or article may readily be distinguished from the bag or article to be loaded. Otherwise the discharge and pick up actions may be so rapid as to defeat ability of the eye to follow the "actual bag exchanging movements when the train is traveling relatively fast.

Inward swing of gate l3 may be limited by the engagement of vane l2 with 23. Outward swing of saidgate may be limited by the engagement of take-on arm l4 with the vertical edge of doorway 4. Or suitable stopsmay otherwise be provided as desired.

For an example of a suitable electrical wiring diagram andof a suitable remote electric control,

system which may beemployed with the struc-. tures of these improvements, reference maybe had to my copending application Serial No. 337,625, filed May 28, 1940, wherein counterparts of the herein disclosed auxiliary rail 39 and cats whisker 33 will be observed. It will suffice here to mention that auxiliary rail 39 is designed to be manually switched into or out of circuit with the positive binding post of the before mentioned battery or toy transformer shown in thesaidcopending application to whose negative terminal .is connected the traction rail 35. Thus at some remote point it may be determined upon whatoccasions the contacting of current c0llector'33 with auxiliary rail 39 will or will not 'cause the described automatic mail bag 'exchangingperformance.

There is thus provided horizontally swinging article motivating instrumentalitie's in a system of apparatus which automatically determinesthe.

sequence and timing of unloading and loading operations in accordance with the distance of the car from the track-side rest 42.
