United States Patent O M 3 G33 933 Accessory coNrnoLLhn non "for RAILWAY Willis E. Rexford, Girard, Pa., assigner to Louis Marx de Company, Inc., New York, NY., a corporation of New York Filed June 25, 1953, Ser. No. 744,361 9 Claims. (Cl. 246-246) rlhis invention relates to toy railways, and more pan ticularly to a controller forming a part of the track system for controlling accessories.

Toy railways have a variety of accessories such as a crossing gate, a semaphore, a block signal, a two-light flashing signal, a track-side bell or whistle, mechanisms for loading or unloading logs, barrels, baggage, or other items, automatic control of track switches, and so on. These are usually controlled by the approach and departure of a moving train, or the position of a stopped train.

There is a trend toward miniature toy railways using the so-called HO gage. The track for such trains is usually of the two-rail type, with the rails insulated from one another, and commonily mounted on an insulation base simulating cross ties. The general object of the present invention is to provide an accessory controller which forms a part of a two-rail track system, and more specifically, an HO gage track system.

More specific objects of the invention are to provide an accessory controllerwhich is simple in construction, easy to manufacture, dependable in operation, which will not interfere with the nor-mal operation of HO gage trains, and which does not require the cars to have metal wheels.

Further objects of the invention are to provide an accessory controller which will provide continuous closing of an electrical circuit; a modified controller which will provide intermittent closing, as for the operation of a two-'light flashing signal or a bell; and to provide a controller the base and most of the parts of which may be used with either the continuous or intermittent controller.

To accomplish the foregoing general objects, and other more specific objects which will hereinafter appear, the invention resides in the controller and track elements and their relation one to another as are hereinafter more particularly described in the following specification. The specification is accompanied by drawings in which:

FIG. 18 is a schematic elevation of a train to show the effective spacing of the operating projections of the train.

Referring to the drawing, and more particularly to FIG. 13, the accessory controller replaces one length or section of track, and for this purpose comprises an insulation base generally designated 12, with metal rails 14 thereon. There are superposed contacts which are concealed by a relatively long ramp 16 overlying the base and the contacts between the rails le. The contacts are connected by conductors 13 and 2li to an accessory 22, and a power supply source is connected to leads L1 and L2. The arrangement and dimensioning of the ramp iti is such that a passing train bears down on the ramp and closes the contacts, thereby closing the supply circuit to the accessory 22. In this case, the contacts are closed continuously.

Referring now to FIG. 12, the controller there shown comprises a similar base 12 with metal rails 14 and a ramp, but the ramp 22 here shown is shorter than .the ramp le. Two pairs of superposed normally open spring contacts, not shown, are disposed beneath the ramp 22. There is a common connection 24, and separated connections 26 and 28 to the spaced pairs of contacts. These lead to a two-light hashing signal 30, while a common conductor 24, and another common conductor 32 lead to a suitable power supply connected at L1, L2. In this case the circuit is closed intermittently.

The arrangement shown in FlG. 13 may be considered, electrically, as a single-pole single-throw switch, while the arrangement shown in PIG. 12 may be considered, electrically, to be a singlepole double-throw switch.

Referring now to FIG. 16, the base 12 is preferably a one-piece molded insulation base, and it preferably simulates ties 34. One of the rails is indicated at i4, while the ramp is shown at 22. There are two oppositely directed pairs of superposed, normally open, spring contacts ydisposed longitudinally or" the base `l2, and secured near the center thereof. The upper and lower contacts of one pair are shown at 36 and 3S, the latter preferably having a contact point `fill. yThe other pair of contacts is shown at 42 44, the latter having a contact point at 46. The contacts 3e and 42 are preferably a single continuous piece of very thin spring metal secured at its center by means of an eyelet 48. The contacts 33 and 44 are preferably separate contacts secured by eyelets Sil and y52.

Connectors extend transversely from the contacts to the side of the base, and one of these is most clearly shown at 54 in FIG. l5. This connector is preferably made of spring metal and its outer end is bent upward at 5d, and outward at 58. The upwardly bent part at 5'6 is provided with a hole to receive the stripped end 60 of a flexible insulated wire 62. The sidewall 6d of the base is preferably apertured or notched, as is best shown at 66 in FIG. 1l. On reflection it will be evident that by pressing the tab 58 downward, the wire 66 may be slid through the then-aligned apertures 66 and 56, and that on release of tab 53 the wire will be held by the resilient upward restoring movement of the spring connector 54 (FIG. l5).

On reference to any of FIGS. 7, 8, 9, 1l, 12 and 13, it will be seen that there are three such connectors affording convenient connection of three wires. Moreover, from inspection of FlGS. 8, 9 and 17, it will be understood that the center connector leads to both upper contact-s, while the side connectors lead to the lower contac- ts 38 and 44.

Both the shorter ramp 22 and the longer ramp 16 are long relative to the contacts. The ramp is preferably made of insulation material, such as a thin sheet plastics material, or if made of thin sheet metal, it is preferably coated with insulation material. This precaution is not essential with all HO gage trains, but is desirable if the controller is to be usable with most such trains without concern over possible short circuiting of some of the electrically charged parts of the train.

The ends of ramp Z2 are slid beneath yokes 7d (FIG. 7). These yokes are preferably integral with the base, and preferably are raised portions of a simulated tie7 the raised portion being located between the rails. This is clearly shown at 70 in FIG. 1 and FIG. 7, as well as in FIG. 16. In FIG. 7 it will be seen that the ends of the ramp are necked to reduced width in order to be received in the yokes 70, and to locate the ramp against longitudinal movement while affording vertical movement. In other Words, the shoulders formed by the necking of the ends of the ramp prevent any substantial displacement yof the ramp out of its desired position.

The shorter ramp 22 shown in FIG. 16 has a length somewhat less than the spacing of most of the operating projections on the train. In most cases, the operating projection is the coupling mechanism between cars, and referring to FIG. 18, the cars 72, 74, and '76 are coupled at 80 and 82. The effective length of a car, or the spacing of the operating projections, is indicated by the dimensions 84, 86 and 88. It will be understood that the train may be much longer, with many more couplings. In one specific case the effective length of a car is six inches, and the short ramp is five and one quarter inches long.

When a first operating projection reaches the ramp 22 it depresses one end, and consequently closes the contacts 36, 38, while the contacts `42, '44 remain open, as shown in FIG. 17. When the projection reaches the other half of the ramp, the contacts 42, 44 close and the contacts 36, 38 open. This is so because in general only one operating projection bears on the ramp at any one time. Thus the intermittent or flashing action desired for some accessories, such as the two-light ash signal shown in FIG. 12, is obtained.

On the other hand, when the ramp is longer than the spacing 86, 88 shown in FIG. 18, a consequence is that two operating projections bear on the ramp much of the time, thus keeping the contacts closed. The desired result is further assured by connecting the two pairs of contacts together, which might be done by running the lead 2t) in FIG. 13 to both outer connectors, but which is more conveniently done here by a connection in the controller'itself. Referring to FIG. 15, there is a channel 90 to receive afshort length of conductor, and referring to FIG. 9, the channel 91B has a bare wire conductor 9,2 therein, the said conductor underlying the ends 94 of both outer connectors, thereby shunting the same. Thus with either end down the circuit is closed. In the specific casementionedabove the longer ramp is six and one half inches long.v The track section is seven and one half inches long.

A preferred form of molded base is shown in FIGS. 1 through 6 of the drawing. This base is so designed that it may be used for either type of accessory controller, that is the one with the short ramp or the one with the long ramp. The simulated ties are indicated at 34. They are connected by cross-connections 96 which preferably underlie the rails so'as to be concealed thereby. The particular rails here shown are inverted channels of sheet metal, and the base is provided with ridges 98 over which the sheet metal rails are placed. Y However, rails made of vsolid metal are even more common, and may equally well be employed here, the sole change then needed being to omit the ridges 98, and to add means to hold the rails on the base. If U-shaped staples are employed, which are common, the base is provided with appropriate holes at intervals to receive the said staples, the upper ends of which are bent toward one another around the parallel edges of the bottom flange of the solid metal rail. In general, the advantages of the present construction are independent of the specific nature of the rail used.

The base has a pair of ridges y (FIGS. 1 and 5) between which the upper contact spring (36, .42 in FIG.17) is secured by means of an eyelet passing through hole 102 (FIGS. l and 5). The lower contacts (38 and 44 in FIG. 17) are secured by eyelets passing through holes V104 and 106 (FIG. 1). The upwardy directed tabs of the transverse connectors pass through slots indicated at `108 (FIGS. 1 and 5), these being aligned with the holes 102, 194 and l106, so that the same eyelet maybe used for both the contact and the connector. The base has the yokes 70 and also another pair of yokes spaced further apart, as indicated at 116. These receive the ends of the longer ramp when the longer ramp is used.

FIG. 2 shows the apertures 66 in wall 64, previously referred to in connection with FIGS. 11 and 15 as receiving the wires. FIG. 3 shows the bottom of the base, including three transverse recesses 11-2 for the connectors,

, and openings 114 and recesses 116 for the bottom contacts. There is also a groove 90 for receiving the shunt connection wire between the two bottoni contacts.

FIG. 4 shows how the yokes liltl and 76 and the adjacent par- ts 1,18 of the base are sloped to more readily receive the ends of the ramp when assembling the ramp with the base. On reiiection it will be understood that the base may be molded between the halves of a simple two-part mold, there being no undercuts requiring retractible cores. It will also be understood thatthe base, as molded, includes appropriate guides, holes and slots which facilitate assembly with the metal parts.

FIGS. 7 and 8 show the assembly ofthe base with a short ramp 22, while FIGS. 9 and l0 show the assembly of the base with a long ramp 16. These drawings include the contacts, the connectors 54, and the railsr14, as well as the ramp 16 or 22. In FIG. 7 the middle portion of ramp' 22 has been broken away to expose the upper contacts 42, 36, and a part of contact 36 has been broken away to expose the lower contact`38.

In FIG. l1, one tab 58 has been depressed to receive a wire 60, while the other two tabs are still in raised position.

Disregarding the rails, the entire assembly requires only three small eyelets, and the contacts and connectors, held by the eyelets, cannot turn or pivot because they are received in recesses which hold them `against turning. The rails are secured in whatever way is applicable, to the track system in general. In the present case, the sheet metal rails are held by bending small tongues beneath the base, as shown at in FIGS. 8 and 9. When solid metal railsV are used, they may be fastened in any other conventional fashion,as by means of U-shaped staples referred to above.

It will be understood that the resilient sheet metal used for the contacts is exceedingly thin. The restoring force is just enough to raise the ramp. This is so in order not to exert a force tending to derail a train passing Over the ramp. The ramp itself is thin and light and is freely movable up and down in the yokes which locate the same. The relative displacement of the eyelet or deection point of the upper and lower springs is such .that a slight wiping action occurs on the contacts, tending to keep the contacts clean.

It is believed that the construction, method of assembly, and operation of the improved'accessory controller, as well as the advantages thereof, will be apparent from the foregoing detailed description. It will also be apparent that while the invention has been described in a preferred form, changes may be made in the structure shown withont departing from the scope of the invention, as sought to be defined in the following claims:
